Detailed Description

The foregoing and other technical matters, features and effects of the present invention will be described in detail with reference to the accompanying drawings 1 to 13.

Embodiment 1, this embodiment provides a fixing device of a drainage tube 2 for abdominal tumor surgery, as shown in fig. 1, comprising a fixing base 1 (made of medical rubber), a drainage tube 2, and a through hole 3 provided on the fixing base 1 and matching with the drainage tube 2, when in use, a medical staff firstly passes the drainage tube 2 through the through hole 3 on the fixed seat 1 and inserts one end of the through hole 3 into the drainage port and inserts the drainage port into the depth of four to five centimeters in the abdominal cavity of a patient through the drainage port (the medical staff needs to perform incision on the part to be drained of the medical staff in advance according to the condition of the patient, namely, the drainage port), and then the drainage port is sewed around the drainage tube 2 through a suture, in the suturing process, a suture is enabled to bypass the drainage tube 2 so as to achieve the effect of fixing the drainage tube 2, then the fixing seat 1 is buckled at the drainage opening of a patient, and the fixing seat 1 is stuck to the skin surface of the patient through a medical adhesive tape (so as to achieve the drainage effect);

the improvement of the scheme is that: as shown in the attached drawing 2, an L-shaped frame 4 is installed on a fixed seat 1, a spiral groove hole 6 is formed in the L-shaped frame 4, a containing cavity 5 is formed in the position, provided with the spiral groove hole 6, of the L-shaped frame 4, and a columnar air bag 7 is placed in the containing cavity 5 (as shown in the attached drawing 2), when the drainage tube 2 is used in the drainage tube fixing device, the medical care personnel sticks the fixed seat 1 to the skin surface of a patient, the drainage tube 2 penetrating out of a through hole 3 is wound on the L-shaped frame 4, the drainage tube 2 is wound along the extending direction of the spiral groove hole 6 arranged on the L-shaped frame 4 in the winding process (namely, the drainage tube 2 is clamped in the spiral groove hole 6), at the moment, the inner side of the drainage tube 2 is in contact with the columnar air bag 7 arranged in the containing cavity 5, one end, far away from the fixed seat 1, of the drainage tube 2 extends out of the spiral groove hole 6 and is connected with a drainage bag, and when the drainage tube 2 is accidentally touched by the patient or other personnel and is subjected to a large pulling force (generally, the drainage tube 2 is touched by the patient or other personnel (the patient or the drainage tube 2 under the unconscious condition In the process, the acting force is usually generated faster than soil and has instantaneity), one end of the drainage tube 2, which is far away from the fixing base 1, can move along the pulling direction of the pulling force, at this time, because the drainage tube 2 wound on the L-shaped frame 4 is partially positioned in the spiral groove hole 6, when the drainage tube 2 is subjected to the pulling force, the drainage tube 2 wound on the L-shaped frame 4 can move towards the central axis direction close to the accommodating cavity 5 under the limiting action of the spiral groove hole 6, that is, the drainage tube 2 wound on the L-shaped frame 4 contracts and moves towards the direction of the columnar air bag 7 extruded and arranged in the accommodating cavity 5 (thereby realizing the effect of tightening the drainage tube 2), at this time, the columnar air bag 7 is subjected to an instantaneous extrusion force and deforms, and further, part of the air in the columnar air bag 7 enters the annular tube 8 arranged in the fixing base 1 (as shown in figure 5), because the clamping mechanism is arranged in the fixed seat 1, when gas quickly enters the annular tube 8 in a short time, the clamping mechanism can be driven to act, and the drainage tube 2 positioned in the through hole 3 can be clamped and positioned, so that the drainage tube can be prevented from exiting from the drainage port due to the pulling force;

in the above-mentioned process, receive exogenic action and when being dragged suddenly when drainage tube 2, at first can extrude the column gasbag 7 that is located and holds the chamber 5 and make it produce deformation (can consume partial external force's pulling power at this in-process), it is tight, the location to realize pressing from both sides the drainage tube 2 that is located the through-hole 3 through driving clamping mechanism along with the deformation of column gasbag 7, so as to avoid drainage tube 2 because of receiving outside pulling power and lead to drainage tube 2 to produce the removal for the drainage mouth (lead to drainage tube 2 to drop), drainage tube 2 produces the removal for the drainage mouth and then very easily leads to the drainage mouth position to produce to tear and cause further injury to the patient.

Example 2 in addition to example 1, as shown in fig. 2, an L-shaped tube 9 provided in an L-shaped frame 4 is communicated with a columnar air bag 7 (the L-shaped tube 9 is a hard tube and is fixedly attached to the inside of the L-shaped frame 4), and: as shown in fig. 2, two ends of the accommodating cavity 5 are respectively provided with a sealing structure, so that when the columnar airbag 7 is located in the accommodating cavity 5, two ends of the columnar airbag respectively abut against two ends of the accommodating cavity 5 (so that when the columnar airbag 7 receives the extrusion force from the drainage tube 2, the columnar airbag 7 cannot displace relative to the accommodating cavity 5, and further the columnar airbag 7 deforms and drives the clamping mechanism to act through gas flow);

as shown in figure 5, the clamping mechanism comprises a plurality of clamping cavities 10 arranged around the fixed seat 1 at intervals, and piston plates 11 are slidably mounted in the clamping cavities 10 (springs are connected between the piston plates 11 and the clamping cavities 10, and rubber sealing rings are arranged between the piston plates 11 and the inner walls of the clamping cavities 10 to ensure air tightness), one ends of the clamping cavities 10 far away from the through holes 3 are communicated with the columnar air bag 7 (the ends of the clamping cavities 10 facing the drainage tube 2 are communicated with the outside), initially, the arc-shaped clamping plates 13 are arranged at intervals with the drainage tube 2 penetrating through the through holes 3 (the springs connected between the piston plates 11 and the clamping cavities 10 are in a natural state), when the columnar air bag 7 is extruded and deformed, air in the columnar air bag 7 enters the clamping cavities 10, and as shown in figure 6, the air entering the clamping cavities 10 forces the piston plates 11 to move in the clamping cavities 10 towards the direction close to the drainage tube 2 (so that the piston plates 11 are connected to the piston plates 11, The springs between the clamping cavities 10 are compressed) to drive the elastic telescopic rods 12 to move synchronously (the piston plate 11 is fixedly connected with the elastic telescopic rods 12, and the elastic telescopic rods 12 extend out of the clamping cavities 10), the elastic telescopic plate comprises a fixed end and a telescopic end, the springs are connected between the telescopic end and the fixed end, the fixed end and the piston plate 11 are fixedly installed and are in sliding fit contact with the walls of the clamping cavities 10, and the telescopic end is fixedly provided with an arc-shaped clamping plate 13;

the piston plate 11 is driven to move towards the direction close to the drainage tube 2 along with the continuous entering of the gas, and then the arc-shaped clamping plate 13 is driven to move towards the drainage tube 2 positioned in the through hole 3 through the elastic telescopic rod 12, so that the effect of clamping the drainage tube 2 is realized, therefore, the piston plate 11 and the arc-shaped clamping plate 13 are connected through the elastic telescopic rod 12, and the situation that the gas entering the clamping cavity 10 is too much due to the overlarge deformation of the columnar gas bag 7 and then the piston plate 11 is driven to move for a long distance, so that the arc-shaped clamping plates 13 can not move continuously due to the fact that the arc-shaped clamping plates 13 are pressed against the drainage tube 2 due to the long distance of the movement of the arc-shaped clamping plates 13 towards the direction close to the drainage tube 2 (three arc-shaped clamping plates 13 are arranged in the scheme and the three arc-shaped clamping plates 13 move along the radial direction of the fixed base 1 and towards the direction of extruding the drainage tube 2 is avoided, when the three arc-shaped clamping plates 13 are abutted with each other, the three arc-shaped clamping plates cannot move continuously), the device is damaged, and the arc-shaped clamping plates 13 and the piston plate 11 are connected through the elastic telescopic rod 12, so that the condition can be better avoided (meanwhile, the drainage tube 2 cannot be irreversibly damaged due to excessive extrusion, and obvious extrusion and crease are generated to influence the subsequent drainage process);

when the external pulling force on the catheter 2 is removed, the piston plate 11 is moved towards the initial position by the spring connected thereto and effects an extrusion of the gas entering the clamping chamber 10 into the cylindrical balloon 7, so that the balloon returns to the initial state.

Embodiment 3, on the basis of embodiment 2, as shown in fig. 6, in order to further reduce the damage to the drainage tube 2 during the clamping and positioning processes of the drainage tube 2, in this embodiment, an arc-shaped suction cup 14 is installed on one side of an arc-shaped clamping plate 13 facing the drainage tube 2, a negative pressure cavity 15 (the side of the negative pressure cavity 15 facing the drainage tube 2 is communicated with the outside) is arranged in the space of the fixing base 1 above the clamping cavity 10, a negative pressure plate 16 is installed in the negative pressure cavity 15 in a sliding manner (the contact part of the negative pressure plate 16 and the negative pressure cavity 15 in a sliding fit manner is provided with a sealing rubber ring), an L-shaped rod (not numbered in the figure) extending out of the negative pressure cavity 15 is fixedly installed on the negative pressure plate 16, one end of the L-shaped rod extending out of the negative pressure cavity 15 is connected with the fixed end of the elastic telescopic rod 12, and hard tubes (the hard tubes are respectively arranged on one side of the arc-shaped clamping plate 13 facing the negative pressure cavity 15 and one side of the negative pressure cavity 15 far away from the arc-shaped clamping plate 13 and the hard tubes are respectively connected with the corresponding negative pressure cavity 15, The arc-shaped suction cups 14 are communicated), the hard tubes at the two ends are connected through the pressure-resistant hose 21 (the arc-shaped clamping plate 13 moves relative to the negative pressure cavity 15, so that the two hard tubes are connected through the pressure-resistant hose 21);

when the columnar airbag 7 is squeezed and gas begins to enter the clamping cavity 10, the movement of the piston plate 11 will synchronously drive the negative pressure plate 16 to move in the negative pressure cavity 15 towards the direction close to the drainage tube 2 through the elastic telescopic rod 12, when the arc-shaped suction cup 14 mounted on the arc-shaped clamping plate 13 does not collide with the wall of the drainage tube 2, the movement of the negative pressure plate 16 in the negative pressure cavity 15 will discharge the gas at the right side of the negative pressure plate 16 outwards out of the negative pressure cavity 15 and suck the external gas into the negative pressure cavity 15 at the left side of the negative pressure plate 16 through the arc-shaped suction cup 14, the hard tube and the pressure-resistant hose 21 (as shown in figure 6), so that when the piston plate 11 moves to make the arc-shaped suction cup 14 mounted on the arc-shaped clamping plate 13 collide with the wall of the drainage tube 2, the arc-shaped suction cup 14 and the wall of the drainage tube 2 form a relatively closed space, and then the piston plate 11 will move continuously, then the elastic telescopic rod 12 is squeezed (i.e. the moving end of the elastic telescopic rod 12 is retracted into the fixed end thereof), meanwhile, the fixed end of the elastic telescopic rod 12 drives the negative pressure plate 16 to move continuously, and at the same time, along with the continuous movement of the negative pressure plate 16 in the negative pressure cavity 15, the gas in the closed space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 is pumped into the negative pressure cavity 15 on the left side of the negative pressure plate 16 (so that the air pressure in the arc-shaped suction cup 14 is reduced);

along with the above process, the air in the arc-shaped suction cup 14 is completely pumped into the negative pressure cavity 15, and at this time, the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 is in a vacuum state (the arc-shaped suction cup 14 is tightly adsorbed on the outer wall of the drainage tube 2 under the action of the external atmospheric pressure): because the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 is very small, once the arc-shaped suction cup 14 is contacted with the drainage tube 2 and is abutted together, the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 is pumped into a vacuum state in a short time, at the moment, the negative pressure plate 16 cannot move continuously in the negative pressure cavity 15 (no air exists in the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 and then does not enter the negative pressure cavity 15), at the moment, the positioning effect on the drainage tube 2 is realized by the adsorption force between the arc-shaped suction cup 14 and the wall of the drainage tube 2, and the positioning on the drainage tube 2 is not realized by the clamping force of the arc-shaped clamping plate 13 on the drainage tube, so that the drainage tube 2 is prevented from generating obvious creases and further generating irreversible damage;

note: because the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 is vacuumized and the negative pressure plate 16 cannot continuously move in the negative pressure cavity 15 (the piston plate 11 cannot continuously move in the clamping cavity 10) within a short time after the arc-shaped suction cup 14 is just abutted against the wall of the drainage tube 2, the drainage tube 2 receives a smaller clamping force from the arc-shaped clamping plates 13 along the radial direction of the fixing seat 1, and the positioning effect on the drainage tube 2 is realized mainly by the adsorption force between the arc-shaped suction cup 14 and the wall of the drainage tube 2 (the clamping force which the drainage tube 2 cannot receive is smaller, so that the drainage tube 2 cannot be damaged);

after the external pulling force on the drainage tube 2 is removed, the piston plate 11 moves to the initial position under the action of the spring connected with the piston plate, and simultaneously drives the negative pressure plate 16 to move to the initial position synchronously, along with the movement of the negative pressure plate 16, the gas pumped into the negative pressure cavity 15 is squeezed into the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 through the hard tube and the pressure-resistant hose 21, so that the pressure difference between the space formed by the arc-shaped suction cup 14 and the wall of the drainage tube 2 and the outside is gradually reduced, and finally, the arc-shaped suction cup 14 and the wall of the drainage tube 2 are separated.

Example 4, on the basis of example 3, as shown in fig. 4, a plurality of deformation regions 17 are circumferentially arranged along the outer wall of the contact portion of the drainage tube 2 and the body tissue of the patient at intervals (the wall of the drainage tube 2 in the deformation region 17 has a larger deformation characteristic relative to the wall of the drainage tube 2 between two adjacent deformation regions 17, that is, when being squeezed with the same force, the wall of the drainage tube 2 in the deformation region 17 is more easily deformed), that is, the drainage tube 2 is inserted into the abdominal cavity of the patient through the drainage port, and the plurality of deformation regions 17 are circumferentially arranged on the outer wall of the drainage tube 2 which is arranged outside the body and is close to one end of the drainage port at intervals;

as shown in fig. 13, a strip-shaped balloon 18 is installed at the position of the deformation zone 17, as shown in fig. 11, a channel 19 which penetrates through the strip-shaped balloon 18 up and down is arranged in the strip-shaped balloon 18, initially, when the drainage tube 2 is inserted into the body of the patient through the drainage port and normal drainage is performed, a plurality of strip-shaped balloons 18 arranged at the position of the deformation zone 17 are in a shriveled state and are in a squeezed flat state under the squeezing of a suture line of the drainage port and the drainage tube 2, as shown in a left side view in fig. 12 (at this time, the channel 19 arranged in the strip-shaped balloon 18 is also squeezed and is in a non-conducting state), at this time, the effect of plugging the drainage port is realized under the combined action of a suture line, the drainage tube 2 and the strip-shaped balloons 18 (at this time, two ends of the channel 19 arranged on the strip-shaped balloons 18, one end of which is arranged in the body of the patient, and the other end of which is arranged in the body of the patient), as shown in fig. 10, the upper end of the plurality of the strip-shaped balloons 18 is communicated with a transition cavity 20 arranged on the outer wall of the drainage tube 2, and the transition cavity 20 is communicated with the L-shaped balloon 18 through a low pressure valve The pipe 9 is communicated, as shown in figure 5, the annular pipe 8 is communicated with the L-shaped pipe 9 through a high-pressure valve;

when the columnar air bag 7 is subjected to instantaneous and large extrusion force (i.e. when a patient or other personnel accidentally touches the drainage tube 2 and applies a large and instantaneously generated pulling force on the drainage tube 2), the high-pressure valve is opened and communication between the annular tube 8 and the L-shaped tube 9 is realized (at this time, the low-pressure valve is in a non-conduction state and the L-shaped tube 9 is not communicated with the transition cavity 20), and when the columnar air bag 7 is subjected to slow extrusion force, the low-pressure valve is opened and communication between the transition cavity 20 and the L-shaped tube 9 is realized (at this time, the high-pressure valve is in a non-conduction state and the L-shaped tube 9 is not conducted with the annular tube 8);

as shown in the attached figure 4, an inflammation detection device is arranged in the fixing seat 1 and is connected with a driving mechanism arranged on the L-shaped frame 4, when the inflammation detection device detects that inflammation is generated at the drainage mouth part (the drainage mouth part cut by medical staff is easy to generate inflammation if improper protection or unclean sanitation is performed, once inflammation is generated, inflammation secretion such as pus is generated and is retained in subcutaneous tissue of a patient, if the drainage mouth part is not timely discharged out of the body, the drainage mouth can be infected, further pain is brought to the patient), the inflammation detection device controls the driving mechanism to act and slowly extrude the columnar air bag 7, at the moment, the columnar air bag 7 is extruded and deformed (the deformation process is slow), and a low-pressure valve is opened (the L-shaped pipe 9 is communicated with the transition cavity 20), and the columnar air bag 7 is continuously extruded, then, gas continuously enters the transition cavity 20 through the L-shaped tube 9 and finally enters the strip-shaped balloon 18, the strip-shaped balloon 18 starts to expand after being inflated with the gas (as shown in the right side view of fig. 12), the strip-shaped balloon 18 can only expand in the direction of squeezing the corresponding deformation region 17 due to the limitation of the suture line at the drainage port, as shown in fig. 13, and further the corresponding deformation region 17 is recessed to a certain extent into the drainage tube 2, as shown in fig. 11, so that when the strip-shaped balloon 18 is filled with more gas, the strip-shaped balloon 18 is expanded and the channel 19 arranged inside the strip-shaped balloon 18 is also in a conducting state, at this time, under the condition that the channel 19 arranged in the strip-shaped balloon 18 is conducted, subcutaneous tissue of the patient in the depth of the drainage port is communicated with the outside, and at this time, inflammation discharge substances (such as liquid and the like) generated by the inflammation tissue at the drainage port and in the subcutaneous tissue can be communicated along the expanded strip-shaped balloon 18 The inner channel 19 is discharged to the outside (the discharge of pus helps to eliminate inflammation at the drainage opening and relieve the pain of the patient), thereby accelerating the recovery of the inflammatory condition (the discharge of inflammatory overflow generated at the deep part of subcutaneous tissue can be realized without taking out the drainage tube 2 and further cutting the drainage opening);

note: when inflammation exists in the subcutaneous tissue of a human body and inflammation secretion is generated, the tissue hydraulic pressure of an inflammation part is increased, and at the moment, if the passage 19 in the strip-shaped balloon 18 is communicated, the inflammation secretion can be discharged outwards through the passage 19 under the action of the difference of internal and external pressure (or the pus is removed under the assistance of medical staff, for example, the medical staff can press the skin around the drainage port forcibly so that the pus in the deep part of the drainage port flows outwards along the passage 19 in the strip-shaped balloon 18 due to the extrusion).

Example 5 on the basis of example 4, as shown in fig. 13, the wall of the drainage tube 2 at the upper and lower ends of the deformation region 17 is provided with concave arc slopes 23 (the length of the arc slope 23 inserted into one end of the patient body can be set longer, so as to cover body tissues at different depths below the skin, and when pus is generated in the body tissues at different depths, the body tissues can be drained into the channel 19 through the arc slopes 23), and the arc slopes 23 are mainly arranged so that when the strip balloon 18 is inflated and expanded, the channel 19 at the lower end of the strip balloon 18 (i.e., the end inserted into the patient body) can communicate with inflammation overflow (pus) retained in the subcutaneous tissue of the patient, that is, the inflammation overflow retained in the subcutaneous tissue can enter the channel 19 under the flow guide of the arc slopes 23 and be drained to the outside through the channel 19 (in this example, the arrangement of the arc slopes 23) Equivalent to the effect of a transition);

an arcuate ramp 23 located near one end of the transition chamber 20 (i.e., at the end outside the body) allows pus located in the body to flow along the passage 19 provided in the strip balloon 18 and eventually flow outwardly from the passage 19 through the arcuate ramp 23 for cleaning by medical personnel.

Embodiment 6, on embodiment 4's basis, as shown in fig. 4, inflammation detection device is including installing in fixing base 1 and a plurality of intervals around the stock solution chamber 24 (stock solution chamber 24 is the saturated carbonic acid solution of having stored in, namely, the solution behind the carbon dioxide dissolved water) that through-hole 3 set up, as shown in fig. 8, a plurality of stock solution chamber 24 upper ends communicate jointly have with fixing base 1 with the annular trachea 25 of axle center setting (stock solution chamber 24 and annular trachea 25 intercommunication position are equipped with waterproof ventilated membrane for the carbonic acid solution in the stock solution chamber 24 can't flow into annular trachea 25, can only make carbonic acid solution be heated decomposition and the carbon dioxide gas flow direction that produces to annular trachea 25 in, annotate: when the carbonic acid solution is prepared (namely, a certain amount of carbon dioxide gas is controlled to be dissolved into water), the carbonic acid solution is prepared according to the temperature range of the body temperature of a human body, namely, the certain amount of carbon dioxide gas is dissolved into water in the temperature range of the normal body temperature of the human body and is prepared into a saturated carbonic acid solution in the temperature range (when the temperature of the drainage port exceeds the normal body temperature of the human body, the carbonic acid solution is heated and decomposed to generate the carbon dioxide gas);

the non-woven fabric auxiliary material (used for absorbing exudates flowing out from the drainage port part) is adhered to the bottom wall of the lower end of the liquid storage cavity 24, and when medical workers fix the fixing seat 1 on the skin surface of the drainage port part of a patient through the medical adhesive tape, the non-woven fabric auxiliary material arranged on the bottom wall of the liquid storage cavity 24 is also tightly abutted to the skin around the drainage port, so that the overflow objects seeped out from the drainage port part are absorbed;

as shown in fig. 2 and 4, the circular air tube 25 is communicated with an air chamber 26 arranged in the L-shaped frame 4 through a communicating tube 22, a detection plate 27 is slidably mounted in the air chamber 26 (a rubber sealing ring is arranged at a sliding fit position of the detection plate 27 and the air chamber 26 to ensure air tightness, a spring is connected between the detection plate 27 and the air chamber 26 and is not shown in the figure), the other end of the air chamber 26 is communicated with the outside, a push plate 28 (the outer diameter of the push plate 28 is the same as or slightly smaller than the inner diameter of the accommodating chamber 5) is coaxially fixed outside the air chamber 26 and is positioned in the accommodating chamber 5, one side of the push plate 28 departing from the detection plate 27 is abutted against the cylindrical air bag 7 arranged in the accommodating chamber 5 (when the cylindrical air bag 7 is fully filled with air, one side wall of the push plate 28 departing from the cylindrical air bag 7 is just abutted against one side wall of the air chamber 26 facing the cylindrical air bag 7, when the drainage tube 2 is suddenly subjected to external pulling force and the columnar air bag 7 is extruded to deform, only the gas in the columnar air bag 7 can be discharged through the L-shaped pipe 9, and the pushing plate 28 is not forced to move in the accommodating cavity 5);

if inflammation is generated at the drainage opening of a patient, the temperature of body tissues around the drainage opening is increased (local tissues around the drainage opening are subjected to inflammatory stimulation, so that blood vessels are expanded, blood is accelerated, local catabolism is enhanced, and more heat is generated to cause the skin around the drainage opening to generate heat), at the moment, the skin temperature around the drainage opening is higher than the normal body temperature of a human body, so that carbonic acid solution in a plurality of liquid storage cavities 24 is heated and starts to decompose (the carbon dioxide solubility is reduced when the temperature of saturated carbonic acid solution is increased, so that gas is released outwards), carbon dioxide gas decomposed in a plurality of liquid storage cavities 24 flows to an annular air pipe 25 and flows into an air chamber 26 through a communicating pipe 22, as shown in figure 2, the carbon dioxide gas 27 is forced to move in the air chamber 26 along with the entering of more and more carbon dioxide gas detection plates, further, the pushing plate 28 is driven to synchronously press the columnar air bag 7 in the accommodating cavity 5 (when the air chamber 26 is arranged, the inner diameter of the air chamber 26 is smaller than that of the accommodating cavity 5, so that when only a small amount of carbon dioxide enters the air chamber 26, the columnar air bag 7 can be pressed by the detecting plate 27 and the pushing plate 28, and more air is pressed into the transition cavity 20 through the L-shaped pipe 9 by the columnar air bag 7 due to pressing), the air pressed into the transition cavity 20 further inflates the strip-shaped balloons 18, and the strip-shaped balloons 18 start to expand from an initial dry-shriveled state (the deformation area 17 arranged on the drainage tube 2 is sunken inwards due to pressing, so that the channels 19 arranged in the strip-shaped balloons 18 are communicated);

note: because the speed that carbonic acid solution is heated and outwards decomposes carbon dioxide gas in the stock solution chamber 24 is slower, and then the process that the main seat gasbag was extruded is also a comparatively slow process to realize when the columnar gasbag 7 was extruded, make its inside gas flow into to the transition chamber 20 and then realize aerifing for strip balloon 18 through L venturi tube 9, low pressure valve.

Embodiment 7, on the basis of embodiment 4, as shown in fig. 6, the high pressure valve includes a high step pipe 29 communicated between the annular pipe 8 and the clamping chamber 10, and the smaller diameter end of the high step pipe 29 is communicated with the annular pipe 8 (as shown in fig. 5), a high pressure ball 30 is axially slidably mounted at the larger diameter end of the high step pipe 29, a spring (a spring with a larger elastic coefficient is selected as the spring) is connected between the high pressure ball 30 and the high step pipe 29, and the high pressure ball 30 abuts against the smaller diameter end surface of the high step pipe 29 under the action of the spring, and the diameter of the high pressure ball 30 is between the larger diameter end portion and the smaller diameter end portion of the high step pipe 29;

when the drainage tube 2 is suddenly subjected to a large external pulling force, the columnar airbag 7 is quickly extruded, and the gas in the columnar airbag enters the annular tube 8 through the L-shaped tube 9, the gas entering the annular tube 8 impacts the surface of the high-pressure ball 30 due to a high flow speed, and the high-pressure ball 30 is forced to slide along one end with a larger diameter of the high-step tube 29, so that the high-pressure ball 30 moves towards one end with a smaller diameter far away from the high-step tube 29 (a spring connected between the high-pressure ball 30 and the high-step tube 29 is compressed), a rough conduction state of the high-step tube 29 is realized, and the gas flowing quickly enters the clamping cavity 10 through the high-step tube 29 at the moment and forces the piston plate 11 to act, so that the clamping and the positioning of the drainage tube 2 are realized;

when the external pulling force is removed, the columnar air bag 7 is not squeezed by the drainage tube 2 wound in the spiral groove hole 6, and the air entering the clamping cavity 10 flows in the opposite direction under the action of the piston plate 11 and the spring connected with the piston plate 11, namely, enters the high-step tube 29 again, as shown in fig. 7, the high-pressure ball 30 is internally provided with the step hole 39, the end with the larger diameter of the step hole 39 is axially and slidably provided with the one-way ball 38 connected with the spring (the spring connected with the one-way ball 38 and the diameter of the step hole 39 is a spring with a smaller elastic coefficient), initially, under the action of the spring, the one-way ball 38 is abutted against the end with the smaller diameter of the step hole 39, the diameter of the one-way ball 38 is between the part with the larger diameter of the step hole 39 and the part with the smaller diameter, when the air enters the high-step tube 29 from the annular tube 8, since the check ball 38 abuts against the smaller end of the stepped hole 39, the pressing work of the gas on the high-pressure ball 30 is not affected and the high-pressure ball 30 is forced to move, when the gas flows back from the clamping cavity 10, the gas easily overcomes the elastic force of the spring connected to the check ball 38 and the stepped hole 39 under the action of the piston plate 11 and the spring connected thereto, so that the gas flows back to the annular tube 8 through the stepped hole 39 and finally enters the columnar airbag 7 again, so that the columnar airbag 7 is restored and the piston plate 11 also moves to the initial position.

Embodiment 8, on the basis of embodiment 4, as shown in fig. 10, the low pressure valve includes a low step pipe 31 communicating between the L-shaped pipe 9 and the transition chamber 20, and the smaller diameter end of the low step pipe 31 communicates with the transition chamber 20, a low pressure ball 32 is axially slidably mounted on the larger diameter end of the low step pipe 31 (the diameter of the low pressure ball 32 is between the larger diameter portion and the smaller diameter portion of the low step pipe 31), and a spring is connected between the low pressure ball 32 and the low step pipe 31, and initially, in a natural state, the low pressure ball 32 is located in the larger diameter end of the low step pipe 31 and is not in contact with the smaller diameter end of the low step pipe 31;

when inflammation is generated at the drainage opening part and the temperature of local tissues is higher than the normal temperature of a human body, the carbonic acid solution in the liquid storage cavity 24 gradually decomposes carbon dioxide gas and enters the air chamber 26, so that the columnar airbag 7 is slowly squeezed and deformed, at this time, part of the gas in the columnar airbag 7 is slowly flowed into the end with the larger diameter of the lower step pipe 31 through the L-shaped pipe 9 due to the squeezing (because the gas flow rate is slow at this time, the high-pressure ball 30 arranged in the high step pipe 29 cannot be pushed, at this time, the high step pipe 29 is in a non-conducting state), the gas entering the lower step pipe 31 enters the end with the smaller diameter of the lower step pipe 31 through the gap between the low-pressure ball 32 and the inner wall of the lower step pipe 31 (the low-pressure ball 32 does not move substantially in the end with the larger diameter of the lower step pipe 31), as shown in fig. 10, finally enters the transition cavity 20 to realize the effect of inflating the strip-shaped balloons 18;

when the pus at the drainage port is discharged completely and the medical staff sterilizes the pus, the skin temperature at the drainage port is reduced until the skin temperature is reduced to the normal temperature range of the human body, the solubility of the carbonic acid solution in the liquid storage cavity 24 is gradually increased in the process of temperature reduction, so that under the action of the detection plate 27 and the spring connected with the detection plate, the carbon dioxide gas entering the air chamber 26 flows back to the annular air tube 25 through the communication tube 22 and is finally absorbed by the carbonic acid solution in each liquid storage cavity 24, the detection plate 27 synchronously moves to the initial position (synchronously drives the pushing plate 28 to move) in the process, the columnar air bag 7 is not pushed by the pushing plate 28 any more, and the deformation area 17 arranged on the drainage tube 2 begins to extrude the strip-shaped balloon 18 (when the strip-shaped balloon 18 inflates, the deformation area 17 always provides a reaction force for the strip-shaped balloon 18), and the gas in the strip-shaped balloon 18 is forced to flow back into the columnar airbag 7 through the transition cavity 20, the low-step pipe 31 and the L-shaped pipe 9 (since the carbon dioxide gas is absorbed by the carbonic acid solution, the process is slow, and the gas backflow is also slow).

Embodiment 9, on the basis of embodiment 1, as shown in fig. 1, a plurality of air holes 33 are formed in the outer wall of the fixing base 1 at intervals, and the air holes 33 can exchange air in the fixing base 1 with the outside, so that the air is in a circulating state, the drainage port part is always in a dry and ventilating state, inflammation of the drainage port part can be avoided, medical staff can observe the condition of the drainage port part of a patient through the air holes 33, and the drainage condition of body fluid exudates and pus at the drainage port part can be mastered in real time;

if the pus discharge is when more, medical personnel can dismantle drainage tube 2 twine on L shape frame 4 and take off fixing base 1 from patient's skin surface (drainage tube 2 is motionless for drainage mouth position this moment for fixing base 1 removes for drainage tube 2), thereby will locate drainage tube 2 and leak at the outer arc slope 23 of patient's one end of body, be convenient for medical personnel clear up the pus that the water conservancy diversion came out (treat to accomplish the clearance after, twine drainage tube 2 in L shape frame 4 and be fixed in patient's skin surface with fixing base 1 once more).

Embodiment 10, on the basis of embodiment 1, as shown in fig. 1, a limit bolt 34 is engaged with one end of the L-shaped frame 4 away from the fixing base 1 along a radial direction thereof by a screw thread, and the limit bolt 34 is rotatably installed with a limit plate 35 installed to slide along the radial direction of the L-shaped frame 4, after the medical staff winds the drainage tube 2 on the L-shaped frame 4 along the direction of the spiral slot 6, the limit bolt 34 is screwed and the limit plate 35 is driven toward the radial end of the L-shaped frame 4, so as to clamp and limit the end of the drainage tube 2 away from the fixing base 1 (to avoid the drainage tube 2 wound in the spiral slot 6 from loosening, only a small contact force is required), as shown in fig. 3, diversion grooves 37 communicating with the spiral slot 6 are respectively arranged at the bending part of the L-shaped frame 4 and the position where the limit plate 35 is arranged, as shown in fig. 1, so that the drainage tube 2 is cut into the spiral slot 6 under the guiding action of the diversion grooves 37 and extends outward from the spiral slot 6 (actually extends out of the spiral slot 6) (actually The transitional effect).
