Description

Technical Field

[0001] The invention belongs to the technical field of pneumothorax decompression, and in particular relates to a pediatric pneumothorax decompression device. Background Art

[0002] In order to quickly relieve lung compression caused by pneumothorax in children and restore normal lung function, puncture is a commonly used emergency treatment method. Pneumothorax is treated by inserting a needle or catheter into the chest cavity and extracting the accumulated air.

[0003] When performing puncture decompression, it may be necessary to empty the syringe multiple times. Since the puncture needle and the syringe are connected by a latex tube, if there is a lot of air accumulated in the pneumothorax, the doctor needs to use hemostatic forceps to clamp the latex tube and then disconnect the syringe and the latex tube, and then connect the syringe to the latex tube again after emptying the syringe, recheck the airtightness and then draw again. The whole process is cumbersome and time-consuming and cannot be performed by one person. At the same time, since children's lungs have poor elasticity, too fast decompression may cause gas to suddenly enter the blood circulation, causing air embolism or causing severe lung collapse. Therefore, when using a syringe to draw, it needs to be slower and gentler to avoid too fast decompression causing problems such as shortness of breath, hypoxia or excessive heart burden. However, the extraction speed of the existing syringe is manually controlled by medical staff, which has certain safety hazards when used and is inconvenient to use. Summary of the invention

[0008] Preferably, the through hole is located above the auxiliary tube, and the sealing ring is located between the through hole and the inner wall of the auxiliary tube.

[0009] Preferably, the outer wall of the transmission tube is provided with threads, the inner wall of the pulling tube is provided with positive and negative thread grooves matching with the outer wall of the transmission tube, and the pulling tube and the transmission tube are movably connected via threads.

[0010] Preferably, the puncture needle is provided with an annular disk, a retaining ring is symmetrically mounted on one side of the annular disk close to the syringe, and the annular disk and the syringe are movably connected via a transmission structure, and the transmission structure is used to control the distance between the annular disk and the syringe.

[0011] Preferably, the transmission structure includes an annular airbag, a connecting hose, a connecting tube, an insertion rod and a safety valve, the connecting tube is symmetrically installed on the outer wall of the syringe, a safety valve is fixedly installed in the middle of the connecting tube, the insertion rod is symmetrically installed on the side wall of the sliding rod close to the syringe, the insertion rod is inserted in the connecting tube, an annular airbag is arranged on the end surface of the syringe on the side away from the sliding rod, the two ends of the annular airbag are respectively adhered to the annular disk and the outer wall of the syringe, and connecting hoses are symmetrically arranged on both sides of the annular airbag, the connecting hose is adhered to the other end of the connecting tube, and the connecting tube is symmetrically provided with perforations on the outer wall close to the sliding rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention is provided with a sliding rod, a circular ring and a through hole. When in use, the sliding rod is pulled to drive the circular ring to slide inside the slide groove, and after closing the air vent and the exhaust hole, the pulling tube and the sealing ring are driven to move outward, so that the gas in the child's body passes through the puncture needle and the connecting tube under the action of pressure and enters the interior of the needle tube, thereby completing the gas extraction. When emptying the syringe, it is only necessary to push the sliding rod to drive the circular ring to slide in the opposite direction inside the slide groove, reopening the air vent and the exhaust hole. At this time, the air inside the needle tube is directly connected to the outside world through the through hole, the transmission tube, the air vent and the exhaust hole. Therefore, when the pulling tube is pushed inward, the gas inside the needle tube will not be injected back into the child's body.

[0015] (2) The present invention is provided with a connecting tube, an insertion rod and an annular air bag, etc. When performing puncture, medical staff need to pull the sliding rod repeatedly to extract air. When the sliding rod moves, it drives the insertion rod to slide repeatedly inside the connecting tube, so that the external air is injected into the annular air bag through the through hole via the safety valve and the connecting hose, so that the volume of the annular air bag gradually expands, and then gradually increases the distance between the annular disk and the syringe. Since the annular disk is in close contact with the skin, the puncture needle can only move outward, preventing the end of the puncture needle from contacting the organ after the gas is extracted, causing damage to the organ.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 3-Figure 5 As shown, the present invention provides the following technical solutions: a pediatric pneumothorax decompression device comprises a syringe 4, the interior of the syringe 4 is fixedly connected to a transmission tube 8 through a filtering structure, the transmission tube 8 is provided with through holes 10 at equal intervals on one side of the outer wall away from the opening of the syringe 4, and a pulling tube 7 is sleeved on the transmission tube 8, a sealing ring 6 is fixedly installed on the outer wall side of the pulling tube 7 close to the through hole 10, and a sliding groove 14 is provided on the inner wall side of the pulling tube 7 close to the transmission tube 8, a rubber ring 25 is fixedly installed on the inner wall side of the sliding groove 14 close to the transmission tube 8, and air holes 17 are also provided on the inner wall of the sliding groove 14 close to the rubber ring 25 at equal intervals, and the pulling tube 7 is sleeved on the outer wall side of the pulling tube 7 close to the through hole 10, and a sealing ring 6 is fixedly installed on the inner wall side of the pulling tube 7 close to the transmission tube 8, and a rubber ring 25 is fixedly installed on the inner wall side of the sliding groove 14 close to the transmission tube 8. A T-shaped sliding rod 9 is inserted into the end of the tube 7 away from the transmission tube 8, and a circular ring 16 is fixedly installed on the outer wall of the sliding rod 9. The circular ring 16 is slidably arranged inside the slide groove 14, and the side wall of the circular ring 16 contacts the side wall of the rubber ring 25. A T-shaped exhaust hole 24 is opened on the end surface of the sliding rod 9 close to the transmission tube 8, and the exhaust hole of the exhaust hole 24 is in contact with the rubber ring 25. The width of the circular ring 16 is greater than the diameter of the air vent 17, and a rubber ring 15 is fixedly installed on the top surface of the circular ring 16. The rubber ring 15 is in close contact with the air vent 17, and the distance between the air vent 17 and the bottom of the slide groove 14 is greater than the width of the circular ring 16.

[0024] According to the above technical solution, when in use, the medical staff pulls the sliding rod 9 outward to drive the ring 16 to slide inside the slide groove 14, and then after the air hole 17 and the exhaust hole 24 are closed by the rubber ring 15 and the rubber ring 25, the pulling tube 7 and the sealing ring 6 are continued to move outward to complete the gas extraction by using the pressure difference. When emptying the syringe, the medical staff only needs to push the sliding rod 9 inward to drive the ring 16 to slide in the opposite direction inside the slide groove 14. At this time, the rubber ring 15 and the rubber ring 25 are in contact with the air hole 17 and the exhaust hole 24. The air hole 17 and the exhaust hole 24 are disengaged, and then the air hole 17 and the exhaust hole 24 are reopened, so that the air inside the syringe 4 is directly connected to the outside through the through hole 10, the transmission tube 8, the exhaust hole 24 and the air hole 17. Therefore, when the pulling tube 7 is pushed inward, the sealing ring 6 will not reversely inject the gas inside the syringe 4 into the child's body. There is no need to disassemble the syringe 4 for emptying. The whole device is fixedly connected, and there is no need to pay special attention to the airtightness problem when using it. It is also convenient to carry, and the method of emptying the syringe is convenient and fast, and easy to use.

[0025] Furthermore, the filtering structure includes a puncture needle 1, a connecting tube 12, an auxiliary tube 5 and a connecting tube 11. The auxiliary tube 5 is fixedly installed on the bottom of the syringe 4 away from the opening, and clean water is arranged inside the auxiliary tube 5. The connecting tube 12 is fixedly installed on the end of the syringe 4 away from the opening, and the internal thread of the connecting tube 12 is connected to the puncture needle 1. An L-shaped connecting tube 11 is fixedly installed inside the syringe 4, one end of the connecting tube 11 is connected to the puncture needle 1, and the other end of the connecting tube 11 is embedded in the clean water inside the auxiliary tube 5. The transmission tube 8 is fixedly installed on the upper part of the connecting tube 11 away from the puncture needle 1. The through hole 10 is located above the auxiliary tube 5, and the sealing ring 6 is located between the through hole 10 and the inner wall of the auxiliary tube 5.

[0026] Please refer to Figure 1 and Figure 3 Since the puncture needle 1 is fixedly installed by threaded connection with the connecting tube 12, the puncture needle 1 can be replaced by rotating and disassembling to meet the usage needs of children of different ages. The puncture needle 1 is connected to the connecting tube 11. When the medical staff pulls the sliding rod 9 outward to extract gas, the gas in the body passes through the connecting tube 11 through the clean water under the action of pressure and enters the interior of the syringe 4. When the sliding rod 9 is pushed inward, due to the existence of the water seal, the outside gas cannot directly enter the child's body, ensuring that the wound remains sterile.

[0027] Furthermore, the outer wall of the transmission tube 8 is provided with threads, and the inner wall of the pulling tube 7 is provided with positive and negative thread grooves matching the outer wall of the transmission tube 8, and the pulling tube 7 and the transmission tube 8 are movably connected through threads.

[0028] Please refer to Figure 1 and Figure 3 When the pulling tube 7 moves outward, since the inner wall of the pulling tube 7 is a forward and reverse thread, due to the threaded connection, the pulling tube 7 switches back and forth between forward rotation and reverse rotation, thereby greatly slowing down the speed of the pulling tube 7 moving outward, ensuring that the pulling tube 7 will not move outward significantly in an instant, ensuring safe use, and since the ring 16 and the rubber ring 15 are both annular structures, while ensuring that the air vent 17 and the exhaust hole 24 are in a closed state, it will not affect the normal rotation of the pulling tube 7. The user only needs to pull the sliding rod 9 to achieve a relatively uniform pulling effect, ensuring that the syringe is drawn more slowly and gently, avoiding problems such as shortness of breath, hypoxia or excessive heart burden caused by excessive decompression.

[0029] Furthermore, an annular disc 2 is pierced on the puncture needle 1, and a snap ring 3 is symmetrically installed on one side of the annular disc 2 close to the syringe 4, and the annular disc 2 and the syringe 4 are movably connected through a transmission structure, and the transmission structure is used to control the distance between the annular disc 2 and the syringe 4. The transmission structure includes an annular airbag 22, a connecting hose 21, a connecting tube 19, an insertion rod 18 and a safety valve 20. The connecting tube 19 is symmetrically installed on the outer wall of the syringe 4, and the safety valve 20 is fixedly installed in the middle of the connecting tube 19. The sliding rod 9 is symmetrically installed on the side wall close to the syringe 4. Insert rod 18, insert rod 18 is inserted into the inside of connecting tube 19, an annular air bag 22 is arranged on the end face of the syringe 4 away from the sliding rod 9, the two ends of the annular air bag 22 are respectively adhered to the outer wall of the annular disc 2 and the syringe 4, and connecting hoses 21 are symmetrically arranged on both sides of the annular air bag 22, and the connecting hoses 21 are adhered to the other end of the connecting tube 19. The outer wall of the connecting tube 19 close to the sliding rod 9 is symmetrically provided with through holes 13, and a sealing plug 23 is fixedly installed at the end of the insert rod 18, and the outer wall of the sealing plug 23 is in close contact with the inner wall of the connecting tube 19.

[0030] Please refer to Figure 1-Figure 4 Before use, by pushing and pulling the sliding rod 9 multiple times, the external gas passes through the perforation 13, passes through the safety valve 20 and the connecting tube 19, and is injected into the annular airbag 22 through the connecting hose 21, so that the annular airbag 22 expands, increases the distance between the annular disc 2 and the syringe 4, shortens the exposed length of the end of the puncture needle 1, and thus controls the puncture depth. When in use, the thumb and index finger can be embedded into the inside of the clamp 3, and then manually fixed to ensure that the annular disc 2, the puncture needle 1 and the syringe 4 will not be offset. The other hand only needs to pull and push the sliding rod 9 to complete the puncture decompression effect, which can be completed by one person and is convenient to use.

[0031] In addition, when the medical staff extracts gas many times and repeatedly pushes and pulls the sliding rod 9, the external gas will also perforate 13 as the push proceeds and pass through the safety valve 20 and the connecting tube 19 to re-enter the interior of the annular airbag 22, further increasing the distance between the annular disc 2 and the syringe 4. Since the annular disc 2 is close to the skin, the puncture needle 1 can only move outward, preventing the end of the puncture needle 1 from contacting the organ when the gas is extracted, causing damage to the organ. After completing the operation, the gas can be released by adjusting the safety valve 20 to reset the annular disc 2.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
