Description

Technical Field

[0001] This invention belongs to the field of puncture point compression technology, specifically referring to an inflatable multifunctional dialysis puncture point compression device. Background Technology

[0002] A puncture site compression device is a medical instrument used to control bleeding. After a puncture or sample collection is completed, the device can apply pressure to the puncture site to promote blood clotting and reduce bleeding.

[0003] The existing pneumatic multifunctional dialysis puncture point compression devices have the following problems: Existing pneumatic multifunctional dialysis puncture point compression devices do not have the function of step-by-step decompression of puncture sites that have been compressed for a long time. They cannot reduce pressure gradually and in stages, thereby reducing the success rate of hemostasis and failing to meet the current clinical needs for pneumatic multifunctional dialysis puncture point compression devices. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of existing technologies, this solution provides an inflatable multifunctional dialysis puncture point compression device that can perform stepwise decompression on puncture sites that have been compressed for a long time, and significantly improve the success rate of hemostasis by gradually reducing the pressure in stages.

[0005] The technical solution adopted in this solution is as follows: This solution proposes an inflatable multifunctional dialysis puncture point compression device, including a compression airbag, connecting buckles, Velcro straps, a pressure-measuring inflation mechanism, and a stepped decompression mechanism. The connecting buckles are symmetrically arranged on both sides of the compression airbag, the Velcro straps are arranged between the connecting buckles, the pressure-measuring inflation mechanism is located on the upper wall of the compression airbag, and the stepped decompression mechanism includes a guide component, a pressure-relieving component, and a positioning component. The guide component is symmetrically arranged on both sides of the compression airbag, the pressure-relieving component is located on the guide component, and the positioning component is located at the end of the guide component away from the compression airbag.

[0006] As a further preferred embodiment of the present invention, the pressure-measuring inflation mechanism includes an inflation / deflation valve, an inflation bladder, and a pressure gauge. The inflation / deflation valve is connected to the upper wall of the compression bladder, and the inflation bladder is located at the end of the inflation / deflation valve away from the compression bladder. The inflation bladder and the inflation / deflation valve are plugged into each other. The pressure gauge is located on one side of the compression bladder, and the pressure gauge's detection end is inserted through the inside of the compression bladder.

[0007] When using it, the hook and loop sides of the Velcro are torn apart and worn on the patient's arm at the puncture site. The inflatable bladder fits against the gauze at the puncture site. Medical staff squeeze the inflatable bladder, and the bladder is inflated through the inflation / deflation valve. The pressure gauge monitors the pressure value inside the inflatable bladder. After the bladder inflates, it causes the gauze to squeeze the patient's puncture site, achieving compression hemostasis.

[0008] Preferably, the guiding assembly includes a guide cylinder and a guide port. The guide cylinder is symmetrically arranged on both sides of the compression airbag, and the guide port is located on the side of the guide cylinder away from the compression airbag. The pressure relief assembly includes a pressure relief port, a pressure relief magnet, a sliding magnet, and a pressure relief spring. The pressure relief port is located between the guide cylinder and the compression airbag. Multiple sets of the pressure relief magnets are located on the side wall of the guide cylinder. The sliding magnet is slidably disposed on the inner wall of the guide cylinder. The pressure relief spring is located between the sliding magnet and the inner wall of the guide cylinder. The positioning assembly includes a positioning sleeve, a positioning rod, and a positioning plate. The positioning sleeve is located inside the guide port. The positioning rod is slidably disposed inside the positioning sleeve and is in contact with the sliding magnet. The positioning plate is located on the side of the positioning rod away from the guide cylinder.

[0009] In use, initially, the pressure relief spring is compressed. When the pressure gauge detects that the air pressure inside the airbag is approaching the set threshold, inflation to the airbag stops. The airbag is then removed from one end of the inflation / deflation valve. Medical personnel push the positioning plate, which in turn pushes the sliding magnet via the positioning rod. The outer diameter of the positioning rod is smaller than the inner diameter of the guide port, creating a gap between the positioning rod and the inner wall of the guide port. The spring's elasticity allows the spring to slide along the inner wall of the guide cylinder towards the end closest to the airbag. Outside air enters the guide cylinder through this gap, and the existing gas in the guide cylinder is replenished into the airbag via the pressure relief port. The sliding magnet seals the pressure relief port. The sliding magnet and the pressure relief magnet are of opposite poles. The pressure relief magnet is fixed to the side wall of the guide cylinder and magnetically attracts the sliding magnet. The sliding magnet, propelled by the gas inside the compression balloon and pulled by the elastic return force of the pressure relief spring, slowly slides along the inner wall of the guide tube toward the end away from the compression balloon. The magnetic force of the pressure relief magnet gradually decreases along the axial direction from the compression balloon toward the positioning plate on the side wall of the guide tube. The magnetic force of the pressure relief magnet at the end of the guide tube closest to the compression balloon is the strongest, so that the patient's puncture site is subjected to the longest compression time under the condition of high pressure inside the compression balloon. As the compression time of the patient's puncture site increases, the gas inside the compression balloon gradually enters the guide tube through the pressure relief port. By reducing the pressure in stages and slowly, rebleeding is effectively prevented, and the success rate of hemostasis is significantly improved. This ensures that the needle hole stops bleeding and allows the blood vessels to gradually return to normal physiological blood flow. After the bleeding at the puncture site is stopped, the medical staff press the inflation / deflation valve to expel the gas inside the balloon, tear open the hook and loop sides of the Velcro, and remove the balloon from the patient's puncture site to complete the hemostasis procedure.

[0010] The beneficial effects achieved by adopting the above structure are as follows: Compared with existing technologies, this solution combines a pressure-measuring inflation mechanism and a stepped decompression mechanism. Through the inclusion of a guide component, a pressure-relieving component, and a positioning component, after inflating and compressing the patient's puncture site, the high-pressure gas slowly pushes a sliding magnet, allowing the gas inside the compression balloon to flow into the balloon through the pressure-relieving port. By gradually reducing the pressure in stages, rebleeding is effectively prevented, significantly improving the hemostasis success rate. Driven by the gas inside the compression balloon and the elastic return force of the pressure-relieving spring, the sliding magnet slowly slides along the inner wall of the guide cylinder towards the end away from the compression balloon. The magnetic force of the pressure-relieving magnet gradually decreases along the axial direction from the compression balloon to the positioning plate on the side wall of the guide cylinder, with the strongest magnetic force at the end of the guide cylinder closest to the compression balloon. This ensures that the patient's puncture site experiences the longest compression time under high pressure inside the compression balloon, preventing further bleeding from the puncture site and allowing the blood vessels to gradually return to normal physiological blood flow.

Therefore, they should not be construed as limitations on this solution.

[0016] like Figures 1-7 As shown, the present invention proposes an inflatable multifunctional dialysis puncture point compression device, comprising a compression airbag 1, a connecting buckle 2, a Velcro strap 3, a pressure-measuring inflation mechanism 4, and a stepped decompression mechanism 8. The connecting buckles 2 are symmetrically arranged on both sides of the compression airbag 1, the Velcro strap 3 is arranged between the connecting buckles 2, the pressure-measuring inflation mechanism 4 is arranged on the upper wall of the compression airbag 1, and the stepped decompression mechanism 8 includes a guide component 9, a pressure relief component 12, and a positioning component 17. The guide component 9 is symmetrically arranged on both sides of the compression airbag 1, the pressure relief component 12 is arranged on the guide component 9, and the positioning component 17 is arranged at the end of the guide component 9 away from the compression airbag 1.

[0017] As a further preferred embodiment of the present invention, the pressure-measuring inflation mechanism 4 includes an inflation / deflation valve 5, an inflation bladder 6, and a pressure gauge 7. The inflation / deflation valve 5 is connected to the upper wall of the compression bladder 1, and the inflation bladder 6 is located at the end of the inflation / deflation valve 5 away from the compression bladder 1. The inflation bladder 6 and the inflation / deflation valve 5 are plugged into each other. The pressure gauge 7 is located on one side of the compression bladder 1, and the detection end of the pressure gauge 7 is inserted through the inside of the compression bladder 1.

[0018] When in use, the female and male sides of the Velcro strap 3 are torn apart and worn on the patient's arm at the puncture site. The inflatable bladder 6 is attached to the gauze at the puncture site. Medical staff squeeze the inflatable bladder 6, and the inflatable bladder 6 inflates into the compression bladder 1 through the inflation / deflation valve 5. The pressure gauge 7 monitors the pressure value inside the inflatable bladder 6. After the compression bladder 1 inflates, it drives the gauze to squeeze the patient's puncture site, thereby compressing and stopping the bleeding at the puncture site.

[0019] Preferably, the guiding assembly 9 includes a guiding cylinder 10 and a guiding port 11. The guiding cylinder 10 is symmetrically arranged on both sides of the compression airbag 1, and the guiding port 11 is located on the side of the guiding cylinder 10 away from the compression airbag 1. The pressure relief assembly 12 includes a pressure relief port 13, a pressure relief magnet 14, a sliding magnet 15, and a pressure relief spring 16. The pressure relief port 13 is located between the guiding cylinder 10 and the compression airbag 1. Multiple sets of pressure relief magnets 14 are located on the side wall of the guiding cylinder 10. The sliding magnet 15 is slidably disposed on the inner wall of the guiding cylinder 10. The pressure relief spring 16 is located between the sliding magnet 15 and the inner wall of the guiding cylinder 10. The positioning assembly 17 includes a positioning sleeve 18, a positioning rod 19, and a positioning plate 20. The positioning sleeve 18 is located inside the guiding port 11. The positioning rod 19 is slidably disposed inside the positioning sleeve 18 and is in contact with the sliding magnet 15. The positioning plate 20 is located on the side of the positioning rod 19 away from the guiding cylinder 10.

[0020] In use, initially, the pressure relief spring 16 is compressed. When the pressure gauge 7 detects that the air pressure inside the compression airbag 1 is close to the set threshold, inflation of the compression airbag 1 stops, and the inflation airbag 6 is pulled out from one end of the inflation / deflation valve 5. Medical staff push the positioning plate 20, which pushes the sliding magnet 15 through the positioning rod 19. The outer diameter of the positioning rod 19 is smaller than the inner wall of the guide port 11, and there is a gap between the positioning rod 19 and the inner wall of the guide port 11. The sliding magnet 15 slides along the inner wall of the guide cylinder 10 towards the end close to the compression airbag 1 using the elastic deformation of the pressure relief spring 16. The gas inside the guide cylinder 10 enters the compression airbag 1 through the pressure relief port 13, and the sliding magnet 15 blocks the pressure relief port 13. The sliding magnet 15 and the pressure relief magnet 14 are set with opposite poles, and the pressure relief magnet 14 is fixed to the side wall of the guide cylinder 10 by magnetic force. The sliding magnet 15 is attracted and, under the push of the gas inside the compression airbag 1 and the elastic return pull of the pressure relief spring 16, slowly slides along the inner wall of the guide cylinder 10 toward the end away from the compression airbag 1. The magnetic force of the pressure relief magnet 14 gradually decreases along the axial direction from the compression airbag 1 to the positioning plate 20 on the side wall of the guide cylinder 10. The magnetic force of the pressure relief magnet 14 at the end of the guide cylinder 10 closest to the compression airbag 1 is the strongest, so that the patient's puncture site is subjected to the longest compression time under the condition of high pressure inside the compression airbag 1. As the compression time of the patient's puncture site increases, the gas inside the compression airbag 1 gradually enters the guide cylinder 10 through the pressure relief port 13. By reducing the pressure in stages and slowly, rebleeding is effectively prevented, and the success rate of hemostasis is significantly improved. This ensures that the needle hole stops bleeding and allows the blood vessels to gradually return to normal physiological blood flow. After the bleeding at the puncture site is stopped, the medical staff press the inflation / deflation valve 5 to release the gas inside the inflation bag 6 and compress the air bag 1. They then tear open the male and female sides of the Velcro strap 3 and remove the air bag 1 from the patient's puncture site, thus completing the hemostasis procedure.

[0021] In practical use, after the needle is removed during hemodialysis, the medical staff will tear apart the female and male sides of the Velcro strap 3 and put it on the patient's arm at the puncture site. The inflatable bladder 6 will fit against the gauze at the puncture site. The medical staff will squeeze the inflatable bladder 6, and the inflatable bladder 6 will inflate the compression bladder 1 through the inflation / deflation valve 5. The pressure gauge 7 will monitor the pressure value inside the inflatable bladder 6. After the compression bladder 1 inflates, it will cause the gauze to squeeze the patient's puncture site to compress and stop the bleeding. When the pressure gauge 7 detects that the air pressure inside the compression bladder 1 is close to the set threshold, it will stop inflating the compression bladder 1 and pull the inflatable bladder 6 off from one end of the inflation / deflation valve 5. Initially, the pressure relief spring 16 is compressed. Medical staff push the positioning plate 20, which in turn pushes the sliding magnet 15 via the positioning rod 19. The outer diameter of the positioning rod 19 is smaller than the inner wall of the guide port 11, creating a gap between the positioning rod 19 and the inner wall of the guide port 11. The sliding magnet 15, utilizing the elastic deformation of the pressure relief spring 16, slides along the inner wall of the guide cylinder 10 towards the end closest to the compression airbag 1. The gap between the positioning rod and the inner wall of the guide port is corrected so that outside air passes through this gap and enters the guide cylinder at the end of the sliding magnet furthest from the compression airbag. The gas is supplied to the inside of the pressure bladder through the pressure relief port. The sliding magnet 15 blocks the pressure relief port 13. The sliding magnet 15 and the pressure relief magnetic block 14 are set with opposite poles. The pressure relief magnetic block 14 is fixed to the side wall of the guide cylinder 10 and attracts the sliding magnet 15 by magnetic force. Under the push of the gas inside the pressure bladder 1 and the elastic return pull of the pressure relief spring 16, the sliding magnet 15 slowly slides along the inner wall of the guide cylinder 10 to the end away from the pressure bladder 1. The air inside the guide cylinder 10 at the end away from the pressure bladder 1 is discharged to the outside through the gap between the positioning rod 19 and the inner wall of the guide port 11. The magnetic force of the pressure-relieving magnetic block 14 gradually decreases along the axial direction from the pressure balloon 1 to the positioning plate 20 on the side wall of the guide cylinder 10. The magnetic force of the pressure-relieving magnetic block 14 at the end of the guide cylinder 10 closest to the pressure balloon 1 is the strongest, so that the patient's puncture site is subjected to the longest compression time under the condition of high pressure inside the pressure balloon 1. As the compression time of the patient's puncture site increases, the gas inside the pressure balloon 1 gradually enters the guide cylinder 10 through the pressure relief port 13. By reducing the pressure in stages and slowly, rebleeding is effectively prevented, and the success rate of hemostasis is significantly improved. This ensures that the needle hole stops bleeding and allows the blood vessels to gradually return to normal physiological blood flow. After hemostasis is achieved at the puncture site, medical staff press the inflation / deflation valve 5 to release the gas inside the inflation bag 6 and compress the air bag 1. They then tear open the male and female sides of the Velcro strap 3 and remove the air bag 1 from the patient's puncture site, thus completing the hemostasis procedure. The procedure can be repeated for the next use.

[0023] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
