Description

Technical Field

[0001] This invention relates to the field of abdominal binder technology, specifically an adjustable inflatable hemostatic abdominal binder. Background Technology

[0002] An abdominal binder is a medical device that combines mechanical compression for hemostasis with postoperative abdominal fixation and support. It is mainly used in the recovery period after surgery, especially after cesarean section and major abdominal surgery. Using an abdominal binder can stabilize the wound and support the abdomen, significantly reduce pain during postoperative activity, improve patient comfort, and encourage early ambulation.

[0003] When using an abdominal binder directly, the tension required to tighten it cannot be directly judged. If the tension is too low, it will not achieve the hemostatic effect. If the tension is too high, it may lead to serious complications such as tissue ischemia and necrosis, nerve damage, increased risk of deep vein thrombosis, difficulty breathing, and increased pain. As a result, the operation of this device is too demanding and needs to be carried out under the guidance of a professional. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes an adjustable inflatable hemostatic abdominal binder, which reduces the difficulty of operation and makes it convenient for family members to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable inflatable hemostatic abdominal binder, comprising an abdominal binder body, wherein hook and loop fasteners are fixedly connected to the side walls of the abdominal binder body, an air bladder placement bag is fixedly connected to the side walls of the abdominal binder body, and an inflatable air bladder is provided inside the air bladder placement bag, a deflation valve is connected to one side wall of the inflatable air bladder, and a pressure detection tube is provided to one side of the inflatable air bladder, a first conduit is connected to one side wall of the pressure detection tube, and one end of the first conduit is connected to the inflatable air bladder, a second conduit is connected to one side wall of the pressure detection tube, and an inflation mechanism is connected to one end of the second conduit, a piston is slidably connected to the inner wall of the pressure detection tube, and a first spring is provided below the piston, a pressure regulating and sealing structure is provided inside the pressure detection tube, and a preset pressure reminder mechanism is connected to the upper end of the pressure detection tube.

[0006] Preferably, the pressure regulating sealing structure includes a sealing ring that is slidably connected to the inner wall of the pressure detection tube, and a vertical tube is slidably sleeved on the inner wall of the sealing ring. The side wall of the vertical tube is provided with a first air hole and a second air hole, and one end of the vertical tube is fixedly connected to the piston.

[0007] The sealing ring includes a first magnet ring, and the outer wall of the first magnet ring is wrapped with a soft sleeve. The outer wall of the pressure detection tube is slidably fitted with a second magnet ring, and the second magnet ring is magnetically coupled to the first magnet ring.

[0008] Preferably, the preset pressure reminder mechanism includes a threaded pipe connected to the pressure detection pipe, and the outer wall of the threaded pipe is threaded with a nut and an outer tube. The inner wall of the threaded pipe is fixedly connected with a conical sleeve, and a conical block is provided inside the conical sleeve. A second spring is provided at one end of the conical block, and one end of the second spring is fixed to the outer tube. A whistle is connected to one end of the outer tube.

[0009] Preferably, the inflation mechanism includes a balloon body, and the side wall of the balloon body has two clearance holes, each of which is equipped with a one-way valve.

[0010] Preferably, the outer wall of the pressure detection tube is marked with graduation lines.

[0011] Preferably, an elastic bandage is fixedly connected to the side wall of the abdominal binder body.

[0012] Preferably, the end of the vertical tube furthest from the piston abuts against the pressure detection tube.

[0013] Preferably, a bolt is threaded onto one side wall of the second magnet ring, one end of which passes through the second magnet ring and abuts against the pressure detection tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention, by setting a pressure regulating sealing structure, can directly seal the inflatable bladder when the pressure reaches the required level during inflation. This prevents gas from entering the inflatable bladder as the inflation mechanism continues to inflate, ensuring the accuracy of the inflatable bladder pressure and preventing the pressure inside the bladder from increasing to a level that could harm the patient, thereby improving the safety of the device.

[0016] 2. This invention, through the use of an outer tube and a whistle, ensures that after the sealing ring blocks the first air hole, gas can only enter the pressure detection tube above the sealing ring, increasing the pressure in the tube. Once the pressure reaches a certain level, it will push open the conical block, allowing gas to escape through the outer tube and whistle. At this point, the whistle will sound, reminding the operator that the pressure of the inflating airbag has reached the preset value. The force of the second spring can be adjusted so that the conical block will not be pushed open during normal inflation. To adjust, the nut can be loosened, and the outer tube rotated to move it, compressing the second spring and thus adjusting its force. Then, the nut can be tightened again. This method is simple and convenient.

[0017] 3. In this invention, when the inflatable airbag is inflated, the increased air pressure compresses the first spring, causing the piston to move. Therefore, the pressure inside the inflatable airbag is directly proportional to the position of the piston. As the piston moves, it can move the vertical tube, adjusting the position of the sealing ring. This allows the sealing ring to seal the first air hole once the pressure inside the inflatable airbag reaches a certain level, preventing further inflation. Thus, when using this device, the pressure setting and adjustment can be done simply by observing the scale and adjusting the position of the sealing ring according to the doctor's instructions. This eliminates the need for doctors to rely on experience to judge the pressure applied to the wound, reducing the difficulty of operation and allowing family members of the patient to operate it directly.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1 to 8 An adjustable inflatable hemostatic abdominal binder includes an abdominal binder body 1. The side walls of the abdominal binder body 1 are respectively fixedly connected to a hook and loop fastener 2 and a loop fastener 3. An airbag placement bag 4 is fixedly connected to the side wall of the abdominal binder body 1, and an inflatable airbag 5 is disposed inside the airbag placement bag 4. A deflation valve 6 is connected to one side wall of the inflatable airbag 5, and a pressure detection tube 7 is disposed on one side of the inflatable airbag 5. A first conduit 8 is connected to one side wall of the pressure detection tube 7, and one end of the first conduit 8 is connected to the inflatable airbag 5. A second conduit 9 is connected to one side wall of the pressure detection tube 7, and one end of the second conduit 9 is connected to an inflation mechanism. A piston 10 is slidably connected to the inner wall of the pressure detection tube 7, and a first spring 11 is disposed below the piston 10. A pressure regulating and sealing structure is disposed inside the pressure detection tube 7, and a preset pressure reminder mechanism is connected to the upper end of the pressure detection tube 7.

[0029] As can be seen from the above structure, by setting a pressure regulating sealing structure, when the inflation bladder 5 is inflated, it can be sealed directly when the pressure of the inflation bladder 5 reaches the required force. This prevents gas from entering the inflation bladder 5 when the inflation mechanism continues to inflate, ensuring the accuracy of the pressure of the inflation bladder 5. This, in turn, ensures that the pressure inside the inflation bladder 5 will not increase to the level that would harm the patient, thereby improving the safety of the device.

[0030] Furthermore, the pressure regulating sealing structure includes a sealing ring 12 that is slidably connected to the inner wall of the pressure detection tube 7, and a vertical tube 13 is slidably sleeved on the inner wall of the sealing ring 12. The side wall of the vertical tube 13 is provided with a first air hole 14 and a second air hole 15, and one end of the vertical tube 13 is fixedly connected to the piston 10.

[0031] The sealing ring 12 includes a first magnetic ring 121, the outer wall of which is covered with a soft sleeve 122. A second magnetic ring 16 is slidably sleeved on the outer wall of the pressure detection tube 7, and the second magnetic ring 16 is magnetically coupled to the first magnetic ring 121. In use, the inflatable airbag 5 is placed inside the airbag placement bag 4, and then the abdominal binder body 1 is wrapped around the patient's abdomen. It is secured using the hook and loop sides of the Velcro strap 2 and 3. Then, the second magnetic ring 16 is slid, causing it to move the sealing ring 12. Once the sealing ring 12 reaches the preset position, it is then inflated... The gas mechanism inflates the air, allowing gas to enter the pressure detection tube 7. The gas entering the pressure detection tube 7 inflates the inflatable airbag 5 through the first air hole 14, the vertical tube 13, the second air hole 15, and the first conduit 8. As the air pressure in the inflatable airbag 5 and the pressure detection tube 7 increases, the air pressure pushes the piston 10, causing the piston 10 to move. The moving piston 10 drives the vertical tube 13 to move downward. After the vertical tube 13 moves to a certain position, the sealing ring 12 blocks the first air hole 14, preventing further gas from entering the inflatable airbag 5 and ensuring the accuracy of the pressure inside the inflatable airbag 5.

[0032] Furthermore, the preset pressure reminder mechanism includes a threaded tube 18 connected to the pressure detection tube 7, and a nut 19 and an outer tube 20 are threadedly fitted onto the outer wall of the threaded tube 18. A conical sleeve 21 is fixedly connected to the inner wall of the threaded tube 18, and a conical block 22 is provided inside the conical sleeve 21. A second spring 23 is provided at one end of the conical block 22, and one end of the second spring 23 is fixed to the outer tube 20. A whistle 24 is connected to one end of the outer tube 20. By setting the outer tube 20 and the whistle 24 to work together, after the sealing ring 12 blocks the first air hole 14, the gas can only enter the pressure detection tube 7 above the sealing ring 12, so that the sealing ring 12... The pressure in the upper pressure detection tube 7 increases. After the air pressure increases to a certain level, it will push open the cone block 22, allowing the gas to be expelled through the outer tube 20 and the whistle 24. At this time, the whistle 24 can make a sound to remind the operator that the pressure of the inflating airbag 5 has reached the preset level. The force of the second spring 23 can be adjusted so that the cone block 22 will not be pushed open during normal inflation. When adjusting, the nut 19 can be loosened, and then the outer tube 20 can be rotated to move the outer tube 20. Moving the outer tube 20 compresses the second spring 23, thereby adjusting the force of the second spring 23. Then, the nut 19 can be tightened again. It is simple and convenient.

[0033] Furthermore, the inflation mechanism includes a balloon body 25, and two clearance holes are provided on the side wall of the balloon body 25. Each clearance hole is equipped with a one-way valve 26. By setting the balloon body 25 and the two one-way valves 26, when one of the balloon bodies 25 is squeezed, one one-way valve 26 closes and the other one-way valve 26 opens, so that the gas inside the balloon body 25 can be expelled. When the balloon body 25 is released, one one-way valve 26 opens and the other one-way valve 26 closes, so that the balloon body 25 can inhale and recover.

[0034] Furthermore, the outer wall of the pressure detection tube 7 is marked with scale lines 27; by setting scale lines 27, the position of the moving second magnet ring 16 can be determined by scale lines 27.

[0035] Furthermore, an elastic bandage 28 is fixedly connected to the side wall of the abdominal binder body 1; by setting the elastic bandage 28, the pressure detection tube 7 and the inflation mechanism can be fixed.

[0036] Furthermore, the end of the vertical tube 13 away from the piston 10 abuts against the pressure detection tube 7; by setting the end of the vertical tube 13 away from the piston 10 to abut against the pressure detection tube 7, the position of the piston 10 can be limited by the vertical tube 13, so that the piston 10 will not block the first conduit 8 when it is at the top.

[0037] Furthermore, a bolt 17 is threaded onto one side wall of the second magnet ring 16, with one end of the bolt 17 passing through the second magnet ring 16 and abutting against the pressure detection tube 7; the second magnet ring 16 can be fixed by setting the bolt 17.

[0038] In this invention, when in use, the inflatable airbag 5 is placed in the airbag placement bag 4, and then the abdominal binder body 1 is wrapped around the patient's abdomen. The hook side 2 and the loop side 3 of the Velcro are used to fix it. After fixing, the bolt 17 is turned off, and then the second magnet ring 16 is slid so that the second magnet ring 16 drives the sealing ring 12 to move. After the sealing ring 12 reaches the preset position, the bolt 17 is tightened again.

[0039] Subsequently, the balloon body 25 is repeatedly squeezed, causing the balloon body 25 to inflate into the pressure detection tube 7 through the second conduit 9. The gas entering the pressure detection tube 7 inflates the balloon 5 through the first air hole 14, the vertical tube 13, the second air hole 15, and the first conduit 8. As the air pressure in the balloon 5 and the pressure detection tube 7 increases, the air pressure pushes the piston 10, causing the piston 10 to move. The moving piston 10 drives the vertical tube 13 to move down. After the vertical tube 13 moves down to a certain position, the sealing ring 12 blocks the first air hole 14. At this time, the gas can only enter the pressure detection tube 7 above the sealing ring 12, causing the pressure in the pressure detection tube 7 above the sealing ring 12 to increase. After the air pressure increases to a certain level, the air pressure will push open the cone block 22, allowing the gas to be discharged through the outer tube 20 and the whistle 24. At this time, the whistle 24 can make a sound to remind the operator that the pressure of the balloon 5 has reached the preset value and inflation can be stopped.

[0040] Then insert the pressure detection tube 7 into the elastic bandage 28 to complete the fixation. It is convenient and simple to use. When the inflated airbag 5 reaches the required pressure and continues to squeeze the main body 25 of the airbag, it can directly remind the operator, which can further facilitate the use of the operator and reduce the requirements of the operator.

[0041] Furthermore, as the air pressure inside the inflatable airbag 5 increases during inflation, it compresses the first spring 11, causing the piston 10 to move. Therefore, the pressure inside the inflatable airbag 5 is directly proportional to the position of the piston 10. When the piston 10 moves, it can move the vertical tube 13, adjusting the position of the sealing ring 12. This allows the sealing ring 12 to seal the first air hole 14 once the pressure inside the inflatable airbag 5 reaches a certain level, preventing the device from inflating the inflatable airbag 5 any further. This allows the device to be set and adjusted according to the doctor's instructions, eliminating the need for doctors to rely on experience to judge the pressure applied to the wound, thus reducing the difficulty of operation and allowing family members of patients to operate it directly.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
