Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
As shown in figure 1, a thoracic drainage on-line monitoring system, including host computer and power module, still include: a chest connecting pipe 4, a breathing adjusting pipe, a liquid seepage flow guide pipe 5, an adjusting pipe support frame and a liquid seepage amount monitoring structure.
The chest connecting tube 4 is used for draining seepage in the thoracic cavity, and one end of the chest connecting tube 4 is inserted into the thoracic cavity. The respiration adjusting tube is communicated with the other end of the connecting tube of the thoracic cavity and is used for eliminating the influence on the liquid seepage column during respiration. The breathing regulation tube includes: a gas conduction pipe 2, a collapsing gasbag 1 and a gas flowmeter. One end of the gas conduction pipe 2 is communicated with the other end of the chest connecting pipe 4. The collapse air bag 1 is made of an inelastic flexible material and is provided with only one through hole and is communicated with the gas conduction pipe 2 through the through hole. The gas flowmeter is arranged in the gas conduction pipe 2, is in communication connection with the upper computer and is simultaneously electrically connected with the power supply module.
One end of the seepage flow guide pipe 5 is communicated with the other end of the chest connecting pipe 4 and is used for guiding seepage. The chest connecting pipe 4, the breathing adjusting pipe and the liquid seepage flow guide pipe 5 form a Y-shaped structure. The chest connecting pipe 4 and the breathing adjusting pipe are positioned on the same straight line, and the diameter of the breathing adjusting pipe is larger than that of the chest connecting pipe 4. The joint of the seepage flow guide pipe 5 and the chest connecting pipe 4 is in fillet connection.
The structure that comprises thorax connecting pipe 4, breathing control tube and sepage honeycomb duct 5 can realize gas-liquid separation for other exchange capacities between thorax and the breathing control tube can be measured. Wherein, the breathing adjusting tube and the chest connecting tube 4 are arranged on the same straight line, so that the air flow can conveniently enter the breathing adjusting tube. Wherein the diameter that is greater than thorax connecting pipe 4 that will breathe the diameter setting of control tube, make the junction of breathing control tube and sepage honeycomb duct 5 be less than thorax connecting pipe 4 and sepage honeycomb duct 5's junction, make when having liquid to come out, can not enter into the breathing control tube, if will link a junction setting on same straight line, then the liquid that can appear being driven by the air current is because speed is too fast, and cross sepage honeycomb duct 5 and enter into the breathing control tube, influence the monitoring ability of breathing control tube to mutual gas.
And the fillet setting of the junction of the weeping honeycomb duct 5 and the thorax connecting pipe 4 of this application can make liquid receive the influence of surface tension and gravity to change flow direction, simultaneously again because the junction of weeping honeycomb duct 5 and breathing control tube is less than the junction of thorax connecting pipe 4 and weeping honeycomb duct 5 for the liquid that does not change flow direction forms the parabola under the influence of gravity, then finally falls into in the weeping honeycomb duct 5. Meanwhile, as the space is enlarged, the speed of the liquid flowing out is correspondingly reduced, and the seepage liquid is ensured not to flow into the breathing regulation tube.
The principle of the breathing adjusting tube is that when the thoracic cavity is contracted, the extruded gas enters the collapse air bag 1, and because the collapse air bag 1 is made of an inelastic flexible material, when no filler is filled in the collapse air bag 1, the air bag can collapse, and when the filler is filled in the collapse air bag 1, the collapse air bag 1 can swell. So that the gas discharged when the thoracic cavity is contracted enters the collapsing bladder 1, the collapsing bladder 1 is supported to some extent, and is finally equalized with the atmospheric pressure. When the thoracic cavity is expanded, the air in the collapse air bag 1 can be sucked, and the air pressure of the seepage flow guide pipe 5 and the seepage quantity monitoring structure cannot be influenced.
Because the gas of combustion gas has certain initial velocity when the thorax contracts, so when gas enters into the gas conduction pipe 2 of breathing control tube, because the radius grow for gas flow rate reduces, has reduced the impact force to collapse gasbag 1, has avoided collapsing to be by the impact expansion back, when retracting automatically again, the fluctuation of production, thereby make appear gaseous torrent in the overall structure, influence gas flowmeter's measurement accuracy.
One end of the adjusting tube support frame is fixedly connected with the breathing adjusting tube, and the other end is fixedly connected with the seepage flow guide tube 5. The control tube support frame includes: the first connection is also, the second connection is also and the connection plate 7. The first connecting ring 3 is sleeved on the breathing adjusting pipe and is connected with the breathing adjusting pipe in a sliding way. The second connecting ring 6 is sleeved on the seepage flow guide pipe 5 and is in sliding connection with the seepage flow guide pipe 5. One end of the connecting plate 7 is hinged with the first connecting ring 3, and the other end is hinged with the second connecting ring 6. And a power supply module is arranged in the connecting plate 7.
The regulation support can be adjusted and fixed the distance between breathing control tube and the sepage flow honeycomb duct for breathe the control tube and can be in on same straight line with thorax connecting pipe 4, and also can adjust the contained angle between sepage flow honeycomb duct and the breathing control tube simultaneously, make better realization liquid-gas separation.
The seepage liquid amount monitoring structure is used for monitoring the seepage liquid amount, and one end of the seepage liquid amount monitoring structure is communicated with the other end of the seepage liquid guide pipe 5. The seepage liquid volume monitoring structure includes: the seepage liquid holds chamber 8, seepage liquid output and adjusts structure, infrared emitter and infrared receiver No. one. The seepage containing cavity 8 is a cavity with two ports and fixed volume and is used for containing seepage, and one end of the seepage containing cavity 8 is communicated with the other end of the seepage guide pipe 5. The seepage output adjusting structure is arranged at the other end of the seepage containing cavity 8 and used for controlling the seepage outflow speed in the seepage containing cavity 8 and is in communication connection with the upper computer. The first infrared emitter is arranged on the side wall of the seepage containing cavity 8 close to the seepage output adjusting structure and is electrically connected with the power supply module. The first infrared receiver is arranged on the side wall of the seepage containing cavity 8 close to the discharge amount adjusting structure, corresponds to the first infrared receiver and is in communication connection with an upper computer. The volume of the exudate accommodating chamber 8 is between 20 ml and 50 ml. While the two ports of the seepage accommodation chamber 8 are not on the same straight line.
The device is used for measuring the seepage quantity, and the seepage speed is dynamically balanced and can be influenced by chest contraction and relaxation, so that the seepage cannot be measured successfully. Therefore, here, the influence of the operation and relaxation of the thoracic cavity on the measurement of the exudate amount is eliminated by the respiration adjustment tube. And then the liquid outlet speed from the seepage containing cavity 8 is adjusted through the seepage output adjusting structure, for example, the liquid outlet speed of the seepage output adjusting structure is adjusted to 50ml/h, then the current seepage flow speed can be judged by observing the height of accumulated liquid in the seepage containing cavity 8, and if no accumulated liquid exists in the seepage containing cavity 8, the current seepage flow speed is less than 50 ml/h. Since the outflow of the seepage from the thorax is discontinuous and irregular, a certain volume of the seepage containment chamber 8 is required for fault tolerance. Therefore, it is preferable that the volume of the exudate accommodation chamber 8 is 50ml and the flow rate of the exudate amount adjustment structure is adjusted to 50 ml/h. Therefore, the medical staff can also judge whether the seepage quantity of the current time is the seepage quantity or not by observing whether the seepage containing cavity 8 is filled with seepage or not and whether the internal bleeding problem occurs or not.
Simultaneously in order to avoid, two ports that the chamber 8 was held to the sepage are relative, and this sepage volume is less again, and the sepage can directly fall into the sepage holds the export of chamber 8 for the luminousness of the unable accurate measurement sepage of infrared receiver, thereby influence final judged result, so hold two ports dislocation set of chamber 8 with the sepage in this application, make it not on same straight line.
In addition, the system of the present application also has its own decision mechanism as to whether internal bleeding is occurring. In particular to a working method of a thoracic drainage on-line monitoring system, which is suitable for the thoracic drainage on-line monitoring system and comprises the following steps: s1: and (5) initializing. S2: and acquiring the real-time ventilation of the gas flowmeter, and sorting the change data of the ventilation. S3: and acquiring the corresponding light transmittance collected by the first infrared receiver. S4: the results of S2 and S3 are combined to determine the chest condition of the patient.
As shown in fig. 2, S2 includes the steps of: a1: and establishing a coordinate system with time as an abscissa and ventilation as an ordinate. A2: and respectively drawing oscillograms on two sides of the abscissa according to the airflow direction of the acquired data. A3: the air flow entering the breathing adjusting tube is drawn above the abscissa as the air inflow. A4: and counting the air inflow through the gas flowmeter every time the thoracic cavity contracts to obtain an air inflow V, comparing the V with the conventional air inflow D1, and if the V is larger than D1, jumping to A12, and if the V is smaller than D1, jumping to A5. A5: the corresponding time is recorded and it is determined whether there is a start time T0 before that time, if there is, a jump a7, if not, a jump a 6. A6: this time is recorded as the start time T0 and jumps to a 4. A7: comparing V with the alarm value D2, if V is larger than D2, jump A4, if V is smaller than D2, jump A8. A8: the time corresponding to V is recorded and the difference between the recorded time and the starting time T0 is calculated to obtain the time T1 for the feeding amount to be from the value less than the normal value to the value less than the warning value. A9: jump A10 if T1 is less than the first time threshold T2, jump A11 if T1 is greater than T2. A10: it is judged that the insertion end of the chest connection tube 4 is clogged. A11: it is determined that the lungs are gradually restored to function and there is no blockage of the chest tube 4, a notification is given to remind the medical staff to reset the values of D1 and D2. A12: the record of the start time T0 before this time is deleted and a jump is made to a 4.
S4 includes the steps of: b1: jump B2 if it is determined that the insertion end of the chest tube 4 is blocked, jump B3 if it is not determined that the insertion end of the chest tube 4 is blocked. B2: if the patient is indicated to have internal bleeding, an alarm is given to inform medical staff to carry out emergency treatment. B3: the luminous flux that an infrared receiver gathered is obtained to calculate the luminousness of current sepage holding chamber 8, and with take place the luminousness when internal hemorrhage and make the contrast, if the luminousness of gathering is greater than the luminousness when internal hemorrhage, then explain that the patient does not take place internal hemorrhage, if the luminousness of gathering is less than the luminousness when internal hemorrhage, then explain that the patient has taken place internal hemorrhage, jump to B2.
In the above method, T2, D1 and D2 are set by medical staff according to the condition of the patient and the actual condition.
The invention monitors whether the chest connecting tube 4 is blocked by monitoring the gas exchange amount between the chest and the breathing adjusting tube, and can also monitor the recovery degree of the patient, when the blockage occurs, the patient can know the blockage at the first time and send an alarm to inform medical care personnel. Simultaneously this application is through the luminousness calculation to the sepage, whether there is a large amount of fibrinogen in monitoring the sepage, monitors whether the internal bleeding takes place, and timely discovery internal bleeding to inform medical personnel.
Of course, the whole body can be cheap due to the special design of the structural part of the system, so that the system cannot be used without the condition of natural sagging of a support, and therefore, when the system is used, the connecting plate 7 and the seepage containing cavity 8 of the adjusting pipe support frame need to be fixed on a bedside or a support or a cabinet for use.
