Firstly, an introduction is made on the hemostatic powder.

The hemostatic powder has effects of clearing heat, cooling blood, promoting blood circulation, removing blood stasis, stopping bleeding and promoting granulation. It is mainly used for treating gastric ulcer and duodenal ulcer complicated with hemorrhage (middle and small amount).

The function principle of the hemostatic powder is that the hemostatic powder has very high absorption effect on liquid, the adsorption of component moisture in blood leads to concentration of platelets, the aggregation speed and the aggregation capacity of the hemostatic powder are enhanced, the rapid water absorption effect can also reduce the liquid volume of a wound part, aggregation is facilitated, after the hemostatic powder absorbs water and expands, certain pressure is formed on surrounding blood vessels to promote hemostasis, and waterproof gel is formed after water absorption, so that the wound is plugged.

A basic description of the inventive process of this patent will now be described.

The inventor of the present patent finds that, for each existing large hospital, when using the hemostatic powder to perform hemostasis on the abdominal cavity or intestinal ulcer combined bleeding part of the patient through a laparoscope or a dodecaliposcope, the elastic drug feeding bottle with the hemostatic powder is usually connected with a hose (drug spraying tube), concretely, the utility model patent "hemostatic powder propeller" of the patent number "201921459447.X" of the prior application can be referred to, when the used hose (drug spraying tube) is inserted into the laparoscope or the dodecaliposcope, and when the tail end of the hose (drug spraying tube) reaches the abdominal cavity or intestinal ulcer combined bleeding part of the patient, the corresponding elastic drug feeding bottle is pressed, so that the hemostatic powder can be sprayed to the abdominal cavity or intestinal ulcer combined bleeding part of the patient through the tail end of the corresponding hose (drug spraying tube) in a pneumatic pushing manner to perform hemostasis.

Although widely used, the inventors of the present patent found that the above-described operation mode still has certain drawbacks and disadvantages.

Specifically, on one hand, at the moment of loosening the corresponding elastic drug feeding bottle, the elastic drug feeding bottle can automatically bulge, so that a small amount of hemostatic powder is sucked outwards to generate reflux due to negative pressure generated by the automatic bulge of the corresponding elastic drug feeding bottle, the use rate of the hemostatic powder is low, and a better hemostatic effect cannot be achieved.

In this regard, the present inventors have gradually conceived and designed the present application by combining clinical experience, through thinking about problems encountered in clinical work, browsing through a great deal of scientific research data and documents, and searching through the website of the national intellectual property office, to solve the relevant technical problems.

The hemostatic powder backflow prevention spray member 1000 according to an embodiment of the present utility model is described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, a hemostatic powder backflow prevention spray member 1000 according to an embodiment of the present utility model includes a resilient push-type balloon 10, a one-way check valve 20, a hemostatic powder introduction cylinder 30, an organ cover type hemostatic powder storage bottle 40, and a spray tube 50 adapted to be inserted into a endoscope;

Wherein, the lower part of the elastic balloon 10 is provided with a hollow connecting seat 101 downwards; the one-way check valve 20 is clamped in the hollow connecting seat 101 to control the gas in the elastic balloon 10 to flow out in one way through the hollow connecting seat 101; the side wall of the upper end of the hemostatic powder guide cylinder 30 is provided with a medicine guide opening 30a, and the top of the hemostatic powder guide cylinder is provided with an air inlet 30b; the mouth of the organ cover type hemostatic powder storage bottle 40 is detachably connected with the drug guiding port 30a; the hollow connecting seat 101 is connected with the air inlet 30b; the lower end of the hemostatic powder introduction cylinder 30 is integrally connected with the upper end of the spray tube 50; the lower end of the spraying tube 50 is crushed and cut to form a flat unidirectional nozzle 501 for driving the styptic powder 70 to be ejected in one direction, specifically, the lower end of the spraying tube 50 is crushed and two sides of the crushed portion are respectively cut into micro-incisions 5011 with a length of about 2.0mm along the length direction of the spraying tube 50, so as to form a flat unidirectional nozzle 501 for driving the styptic powder 70 to be ejected in one direction, specifically, as shown in fig. 4.

Based on the above, it is clear that the present application is mainly used as the blood powder backflow preventing spray member 1000 when being implemented.

Specifically, in the application of the present application, the mouth of the organ cover type hemostatic powder storage bottle 40 with the hemostatic powder 70 is connected to the drug guiding port 30a, and other components are assembled, then the organ cover type hemostatic powder storage bottle 40 is pressed, so that part of the hemostatic powder 70 in the organ cover type hemostatic powder storage bottle is pushed into the hemostatic powder guiding cylinder 30 through the drug guiding port 30a, the spraying tube 50 is inserted into a endoscope, such as a laparoscope and a duodenoscope, and when the end of the spraying tube reaches the abdominal cavity or intestinal ulcer combined bleeding position of a patient, the elastic balloon 10 is gripped, and the gas in the elastic balloon can enter the hemostatic powder guiding cylinder 30, so that the hemostatic powder 70 flowing into the hemostatic powder guiding cylinder can be pneumatically pushed into the spraying tube 50, and finally the flat unidirectional spray nozzle 501 formed at the tail end of the spraying tube 50 can be sprayed to the abdominal cavity or intestinal ulcer combined bleeding position of the patient, so as to achieve hemostasis of the abdominal cavity or intestinal ulcer combined bleeding position of the patient.

For the above operation, the present application has the following advantages:

The present application is provided with the one-way check valve 20 which is clamped inside the hollow connecting seat 101 to control the air in the elastic balloon 10 to flow out in one way through the hollow connecting seat 101, and the lower end of the spraying tube 50 is shrunken, and the two sides of the shrunken part are respectively sheared along the length direction of the spraying tube 50 to form the micro-incisions 5011 with the length of about 2.0mm, so as to form the flat one-way spray nozzle 501 for driving the styptic powder 70 to spray out in one way, therefore, it can be understood that the air stored in the spraying tube 50 will not flow back into the elastic balloon 10 in the opposite direction no matter whether the elastic balloon 10 bulges or not, and the air is intercepted by the flat one-way spray nozzle 501, so that the styptic powder 70 sprayed to the abdominal cavity or the intestinal ulcer combined bleeding part of the patient is not easy to be sucked out in the opposite direction due to suction of negative pressure, and the backflow preventing effect is good, and the use ratio is high.

Furthermore, through the optimization design, the whole structure formed by the application has strong practicability and good use effect.

Further, in the embodiment, referring to fig. 2 and 4, according to an embodiment of the present utility model, the outer wall of the spraying tube 50 is fixedly provided with a metal guide wire 50 adapted to be inserted into the endoscope along the length direction thereof.

Obviously, the metal guide wire 50 must have a certain hardness, so that when it is fixed on the outer wall of the spraying tube 50 along the length direction of the outer wall of the spraying tube 50, a good traction effect and guiding effect can be achieved, so that the spraying tube 50 can be more easily inserted into a laparoscope, a duodenoscope or other endoscopes.

Furthermore, by the above-mentioned optimized design, the spraying tube 50 of the present application can be inserted into a laparoscope, a duodenoscope or other endoscopes, so that the insertion is labor-saving, and the fatigue of medical staff can be greatly reduced.

Preferably, in this embodiment, a groove (not shown) is formed on the outer wall of the spraying tube 50 by recessing inward along the length direction thereof, and the metal wire 50 is fixed to the groove (not shown) by a hot-melt process.

In addition, as shown in fig. 1 and 2, according to an embodiment of the present utility model, the hemostatic powder introduction tube 30 includes a cartridge 301 having an open upper portion and a connector 302 detachably connected to the upper portion of the cartridge 301;

The side wall of the upper end of the medicine storage tube 301 is provided with the medicine guiding opening 30a, and the lower end of the medicine storage tube 301 is connected with the upper end of the spraying tube 50 to form a whole; the connector 302 is detachably inserted into the hollow connecting seat 101, and the upper end of the connector is abutted to the lower end of the one-way check valve 20.

Thus, it can be understood that:

Since the connector 302 is detachably inserted into the hollow connecting seat 101, when the connector 302 is detached from each other, the one-way check valve 20 is conveniently clamped into the hollow connecting seat 101, so that the assembly is convenient when the application leaves a factory to be finished, and when the connector 302 is inserted into the hollow connecting seat 101, the upper end of the connector 302 is abutted to the lower end of the one-way check valve 20, thereby the one-way check valve 20 has good anti-falling effect.

And in the implementation, as shown in fig. 1 and fig. 2, according to one embodiment of the present utility model, the upper end of the connecting head 302 is screwed on the lower portion of the hollow connecting seat 101; the lower end of the connector 302 is in threaded connection with the upper opening of the cartridge 301.

Therefore, the connector 302, the hollow connecting seat 101 and the cartridge 301 have good connection firmness, so that the whole body formed by the application has good integrity and each component is not easy to loose when in actual use.

Preferably, in this embodiment, as also shown in fig. 1 and 2, according to an embodiment of the present utility model, the inner diameter of the medicine storage tube 301 is larger than the inner diameter of the spraying tube 50, and the lower end of the medicine storage tube is formed into a funnel-shaped structure 3011.

Therefore, the lower end of the cartridge 301 is designed as a funnel-shaped structure 3011 so as to smoothly transition to the upper end of the spraying tube 50, so that the hemostatic powder 70 flowing into the cartridge 301 can fall into the spraying tube 50 sufficiently through the funnel-shaped structure, and finally the flat unidirectional nozzle is sprayed out as completely as possible from the tail end of the spraying tube 50, so that the residual hemostatic powder 70 in the cartridge 301 is prevented as much as possible.

Furthermore, through the above-mentioned optimization design, the utilization rate of the hemostatic powder 70 can be effectively improved when the hemostatic powder is specifically used.

Further, in the embodiment, referring to fig. 2 and 3, according to an embodiment of the present utility model, the one-way check valve 20 includes a hollow cylindrical valve body 201, a valve element 202 and a pressing spring 203, wherein the upper and lower ends of the hollow cylindrical valve body are formed to be opened vertically;

wherein, a gas flowing cavity 2011 with an inner diameter larger than the inner diameter of the openings at the upper end and the lower end is arranged at the middle part in the hollow cylindrical valve main body 201 along the up-down direction; the outer diameter of the valve core 202 is smaller than the inner diameter of the gas flow-through cavity 2011, the periphery of the upper top surface of the valve core 202 tightly abuts against the top wall of the gas flow-through cavity 2011, and the lower bottom surface of the valve core 202 is connected with the upper end of the top pressure spring 203; the lower end of the top pressure spring 203 is fixed to the bottom wall of the gas overflow cavity 2011;

When the valve element 202 is pushed downward by a certain pushing force, the pressing spring 203 compresses, the valve element 202 moves downward along the gas flowing cavity 2011, and the openings at the upper and lower ends of the hollow cylindrical valve main body 201 are all communicated with the gas flowing cavity 2011.

Therefore, it can be understood that when the elastic balloon 10 is manually held, the gas in the elastic balloon 10 pushes the valve core 202 downward, when the valve core 202 is pushed downward by a certain pushing force, and when the corresponding pushing force is enough, the pressing spring 203 is compressed, so that the valve core 202 moves downward by a certain stroke along the gas flow-through cavity 2011, at this time, the openings at the upper and lower ends of the hollow cylindrical valve main body 201 are both communicated with the gas flow-through cavity 2011, so that the gas in the elastic balloon 10 can be pushed into the cartridge 301 through the opening at the lower end of the hollow cylindrical valve main body 201, so as to push the hemostatic powder 70 flowing into the cartridge 301 downward into the spray tube 50, and finally drive the hemostatic powder 70 to be sprayed out from the end of the spray tube 50.

On the contrary, after the above-mentioned related operations are performed, the elastic balloon 10 is released, at this time, the valve core 202 is hardly subjected to downward pneumatic thrust, so that it is immediately restored to the initial state, at this time, the top-pressure spring 203 is also restored to the initial state, so that the top surface periphery of the valve core 202 is tightly abutted against the top wall of the gas-passing cavity 2011, thus, under the separation action of the valve core 202, the openings at the upper and lower ends of the hollow cylindrical valve main body 201 are in a non-communication state, and thereafter, no matter whether the elastic balloon 10 is inflated, the gas stored in the spraying tube 50 is reversely returned into the elastic balloon 10, and the cut-off is performed by the flat unidirectional nozzle 501, so that the hemostatic powder 70 sprayed to the abdominal cavity or the intestinal ulcer combined bleeding part of the patient is not easily reversely sucked and outwards due to the suction of negative pressure, and the backflow prevention effect is good, so that the reliable use rate is high.

Further, in practice, according to one embodiment of the present utility model, the hollow cylindrical valve body 201 is screwed to the upper portion of the hollow connection base 101, and the lower end thereof abuts against the upper end of the connection head 302.

Therefore, when the valve core 202 is fixed to the upper portion in the hollow connecting seat 101, the fixation firmness is good and the valve core is not easy to loose.

It should be added that, in implementation, according to an embodiment of the present utility model, the length of the spraying tube 50 and the length of the wire 50 fixed to the outer wall thereof are not less than 80.0cm.

Thus, the length of the product is enough for children, middle-aged people and old people in specific use.

It should be further added that, in practice, the internal volume of the elastic balloon 10 is preferably equal to or slightly greater than the sum of the volumes of the hollow connecting seat 101, the one-way check valve 20, the styptic powder introducing cylinder 30 and the spraying tube 50.

It should be further added that, in the specific implementation, the mouth of the organ cover type hemostatic powder storage bottle 40 is screwed into the drug guiding port 30a, and the duckbill valve 80 for driving the drug to flow unidirectionally from the organ cover type hemostatic powder storage bottle 40 to the hemostatic powder guiding cylinder 30 is further provided in the drug guiding port 30 a.

In this way, even if the hemostatic powder 70 is caused to flow into the hemostatic powder introduction cylinder 30 in the inside thereof by pressing the organ cover type hemostatic powder storage bottle 40, the flow of the hemostatic powder into the hemostatic powder introduction cylinder 30 is stopped by the duckbill valve 80 when it is reset to the initial state, and even if the hemostatic powder flowing into the hemostatic powder introduction cylinder 30 is not easily sucked back into the organ cover type hemostatic powder storage bottle 40, the use of the present application is made more reliable.

Other embodiments, etc., are not illustrated herein.

In summary, in the implementation of the hemostatic powder backflow preventing spray member 1000 provided by the present application, the one-way check valve 20 is provided and is clamped inside the hollow connecting seat 101 to control the air in the elastic balloon 10 to flow out in one direction through the hollow connecting seat 101, the lower end of the spray tube 50 is shrunken, and the two sides of the shrunken portion are respectively cut into 2.0mm long micro-incisions 5011 along the length direction of the spray tube 50 to form a flat one-way spray head 501 for driving the hemostatic powder 70 to be sprayed out in one direction, so it can be understood that the air stored in the spray tube 50 will not flow back into the elastic balloon 10 in the opposite direction, and the air is stopped by the flat one-way spray head 501, so that the hemostatic powder 70 sprayed to the patient or the intestinal ulcer combined bleeding portion is not easily sucked out in the opposite direction due to the negative pressure, and the backflow preventing effect is good, and the usage rate is high.

In addition, in the specific implementation, since the outer wall of the spraying tube 50 is fixedly provided with the metal guide wire 50 suitable for being inserted into the endoscope along the length direction thereof, obviously, the metal guide wire 50 must have a certain hardness, and when the metal guide wire is fixedly arranged on the outer wall of the spraying tube 50 along the length direction of the outer wall of the spraying tube 50, the metal guide wire can have a good traction effect and a guiding effect, so that the spraying tube 50 can be easily inserted into the endoscope such as the laparoscope or the duodenoscope, and the labor is saved during the insertion of the spraying tube 50 into the endoscope such as the laparoscope or the duodenoscope, and the fatigue of medical staff can be greatly relieved through the optimized design.

Furthermore, the hemostatic powder backflow prevention spray member 1000 provided by the application is extremely strong in practicality and excellent in use effect, so that the hemostatic powder backflow prevention spray member has very good market popularization value, is very popular, and can be effectively popularized.
