Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for preventing slippage and compressing the wound to stop bleeding after cesarean section. Background Technology

[0002] The anti-slip wound compression hemostasis device after cesarean section is a special obstetric medical hemostasis instrument used after cesarean section. Its core function is to apply uniform pressure to the surgical incision in the abdomen and the uterine cavity of the parturient to achieve compression hemostasis and reduce bleeding.

[0003] Most existing hemostatic devices use elastic bands to directly compress the wound to stop bleeding, or add sterile sandbags between the elastic band and the incision to enhance the compression effect. However, the pressure of the elastic bands is uneven, and the sterile sandbags are relatively hard and difficult to fit completely against the surface of the incision, which can easily cause uneven local pressure distribution at the incision. In some areas, the pressure concentration increases the risk of tissue damage, thereby reducing the healing effect of the incision. To address these issues, this invention provides a post-cesarean section anti-slip wound compression hemostatic device to solve the above problems. Summary of the Invention

[0004] This invention provides a wound compression hemostasis device to prevent slippage after cesarean section, which solves the technical problem that existing hemostasis devices easily cause uneven local pressure distribution at the incision site, and the risk of tissue damage due to concentrated pressure in some areas, thereby reducing the wound recovery effect.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A cesarean section post-operative wound compression hemostasis device includes: an elastic band with a third airbag installed on the inner side of the elastic band; a compression mechanism located on the outer wall of the elastic band for inflating the third airbag to stop bleeding from the patient's wound, the compression mechanism including auxiliary components disposed on the outer wall of the elastic band; and an adjustment unit located at the end of the elastic band for adjusting the compression force of the third airbag.

[0007] Optionally, the compression mechanism includes a first airbag disposed on one side of the elastic band, a fourth airbag disposed inside the first airbag, a first auxiliary hose installed at each of the two air supply ends of the fourth airbag, and a first one-way valve and a third one-way valve respectively fixedly connected at one end of each of the two first auxiliary hoses through to the outside of the first airbag.

[0008] Optionally, the compression mechanism further includes a first threaded channel rotatably connected to the output end of the third one-way valve, and a second hose is installed at the input end of the third airbag. One end of the second hose extends through the outside of the elastic band and is fixedly connected to a first threaded connector that matches the first threaded channel.

[0009] Optionally, the auxiliary component includes two extrusion plates fixedly connected to the outer wall of the elastic band. Each of the two extrusion plates has a matching groove on its outer wall. The two matching grooves are respectively rotatably connected to a first connecting rod and a second connecting rod via an auxiliary shaft. One end of the first connecting rod is fixedly connected to a connecting shaft, and one end of the second connecting rod is rotatably connected to the outer wall of the connecting shaft.

[0010] Optionally, the auxiliary component further includes a piston chamber fixedly connected to the outer wall of the elastic band. An I-shaped piston rod is slidably connected to the inner side of the piston chamber. A rebound spring is installed between the I-shaped piston rod and the piston chamber. A columnar rod is fixedly connected to one end of the I-shaped piston rod. Two connecting ropes are fixedly connected to one end of the columnar rod through the outside of the piston chamber. One end of the two connecting ropes is fixedly connected to the bottom of the first connecting rod and the second connecting rod, respectively. A driving component for driving the I-shaped piston rod to move is provided on the inner side of the piston chamber.

[0011] Optionally, the driving component includes a second auxiliary hose installed at the output end of the first airbag. One end of the second auxiliary hose is provided with a second one-way valve. The input end and the output end of the second one-way valve are respectively rotatably connected to a second threaded channel and a third threaded channel. The end of the second auxiliary hose is fixedly connected to a second threaded connector that matches the second threaded channel.

[0012] Optionally, the drive component further includes a first hose installed at the gas delivery end of the piston chamber, one end of which is fixedly connected to a third threaded connector that matches the third threaded channel.

[0013] Optionally, the I-shaped piston rod consists of two piston plates and a cylindrical connecting rod, and the first hose is disposed between the two piston plates.

[0014] Optionally, the adjustment unit includes a second airbag disposed on the outer wall of the elastic band. Two sets of limiting straps are fixedly connected to the inner side of the second airbag. An annular strap is disposed on the inner side of each set of limiting straps, and the annular strap is sleeved on the outer wall of the elastic band.

[0015] Optionally, the adjustment unit further includes a third flexible tube slidably connected inside the elastic band, with both ends of the third flexible tube extending to the outside of the elastic band, and both ends of the third flexible tube being installed at the air supply ends of the second airbag and the third airbag.

[0016] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0017] In the above solution, by setting up components such as a third airbag, the third airbag flexibly contacts the wound surface without sharp edges or hard points, which can avoid friction and tearing of sutured wounds and broken skin, protect the integrity of the wound, and avoid skin ulceration and nerve damage caused by excessive local pressure (such as the risk of "local pressure sores" of traditional tourniquets). Moreover, the third airbag can expand and conform to the curvature of the human body by inflation, solving the problem of "poor fit and pressure dead angles" of rigid compression, thereby improving the recovery effect of the cesarean section incision.

[0018] By incorporating components such as the third airbag compression plate, the tension on the incision caused by patient activity (such as turning over or limb extension) is reduced, lowering the risk of wound dehiscence. This is especially suitable for hemostasis care in the early postoperative period (before the wound has healed). The force is transmitted flexibly through the third airbag (non-rigid compression), avoiding direct contact with the incision or surrounding skin, reducing skin redness and damage caused by mechanical friction and compression, improving the safety of care, and thus improving the recovery effect of the incision after cesarean section.

[0019] By setting an adjustment unit, the pressure of the third airbag is prevented from exceeding the optimal hemostatic range due to postural compression (too high pressure leads to tissue ischemia and pressure sores, too low pressure leads to hemostasis failure), maintaining the "effective hemostatic pressure threshold" of the incision. When the patient lies flat, gas recirculation quickly restores the initial compression pressure, preventing recurrent bleeding caused by a sudden drop in pressure. Ultimately, this achieves "dynamic positional static hemostasis" by keeping the hemostatic pressure within an "effective and safe" balance range under dynamic positions such as lying flat and side-lying, thus improving the recovery effect of cesarean section incisions.

[0031] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 9 As shown, this embodiment of the invention provides a cesarean section anti-slip wound compression hemostasis device, comprising: an elastic band 1, on the inner side of which a third airbag 15 is installed; a compression mechanism located on the outer wall of the elastic band 1, used to inflate the third airbag 15 to stop bleeding from the patient's wound, the compression mechanism including auxiliary components disposed on the outer wall of the elastic band 1; and an adjustment unit located at the end of the elastic band 1, used to adjust the compression force of the third airbag 15.

[0033] In this device, the elastic band 1 serves as the basic load-bearing and fixing structure. When worn, it fits snugly against the patient's waist, using its own elastic tension to secure the device and ensure that the inner third airbag 15 is precisely aligned with the cesarean section incision area, preventing displacement. During operation, the compression mechanism drives the third airbag 15 to inflate. The inflated third airbag 15 flexibly conforms to the wound surface, utilizing the uniform diffusion of gas to create a uniform pressure on the wound, achieving hemostasis. The auxiliary components on the outer wall work in sync to further restrict the displacement of the third airbag 15, ensuring the stability of the compression. The adjustment unit, located at the end of the elastic band 1, allows for flexible adjustment of the compression force of the third airbag 15 according to the patient's wound condition. By adding or releasing gas, it prevents excessively high or low local pressure, ensuring that the compression force is always appropriate for effective hemostasis.

[0034] In this device, the elastic band 1's flexible fixing design adapts to patients with different waist sizes, making it convenient to wear and securely fixed. It effectively prevents the device from slipping during patient movement, ensuring continuous and stable hemostasis and solving the problem of insecure fixation caused by traditional elastic band 1 relying solely on its own tension. The auxiliary components on the outer wall work in tandem to further limit the displacement of the third airbag 15, ensuring the stability of the pressure. After inflation, the third airbag 15 flexibly conforms to the curves of the human body, completely fitting the incision surface. This completely solves the shortcomings of traditional sterile sandbags, which are hard and difficult to fit the incision. Simultaneously, the gas pressure evenly distributes the pressure, avoiding localized pressure concentration and reducing the risk of tissue damage due to uneven pressure, thus protecting the integrity of the wound. The adjustment unit allows for flexible control of the pressure intensity, providing sufficient pressure for effective hemostasis while avoiding excessive pressure that could cause skin breakdown or nerve damage (such as local pressure sores), or insufficient pressure that could lead to hemostasis failure. This effectively improves the problem of uncontrollable pressure in traditional hemostasis methods, enhancing the safety and reliability of post-cesarean section hemostasis care and aiding in incision recovery.

[0035] This device uses a combination of three structures—elastic band 1 (fastened with Velcro), compression plate 8 (limiting the third airbag 15), and ring band 12 (positionally restraining the second airbag 14)—to prevent slippage and avoid displacement of the device during patient movement.

[0036] Furthermore, the compression mechanism includes a first airbag 9 disposed on one side of the elastic band 1, a fourth airbag 28 disposed inside the first airbag 9, and a first auxiliary hose 17 installed at each of the two air supply ends of the fourth airbag 28. One end of each of the two first auxiliary hoses 17 extends through to the outside of the first airbag 9 and is fixedly connected to a first one-way valve 10 and a third one-way valve 13, respectively. The compression mechanism also includes a first threaded channel 16 rotatably connected to the output end of the third one-way valve 13. A second hose 7 is installed at the input end of the third airbag 15, and one end of the second hose 7 extends through to the elastic band 1. An externally fixed connection is provided with a first threaded connector that matches the first threaded channel 16. The auxiliary components include two extrusion plates 8 fixedly connected to the outer wall of the elastic band 1. Each of the two extrusion plates 8 has a matching groove on its outer wall. The interior of the two matching grooves is rotatably connected to a first connecting rod 4 and a second connecting rod 5 via an auxiliary shaft 26. One end of the first connecting rod 4 is fixedly connected to a connecting shaft 6, and one end of the second connecting rod 5 is rotatably connected to the outer wall of the connecting shaft 6. The auxiliary components also include a piston chamber 2 fixedly connected to the outer wall of the elastic band 1. An I-shaped slidable connection is provided on the inner side of the piston chamber 2. A piston rod 21, an I-shaped piston rod 21, and a return spring 23 are installed between the piston rod 21 and the piston chamber 2. One end of the I-shaped piston rod 21 is fixedly connected to a cylindrical rod 24. One end of the cylindrical rod 24 extends through to the outside of the piston chamber 2 and is fixedly connected to two connecting ropes 25. One end of each connecting rope 25 is fixedly connected to the bottom of the first connecting rod 4 and the second connecting rod 5, respectively. The inner side of the piston chamber 2 is provided with a driving component for moving the I-shaped piston rod 21. The driving component includes a second auxiliary hose 18 installed at the output end of the first airbag 9. One end of the second auxiliary hose 18 is provided with a... The second check valve 11 has a second threaded channel 19 and a third threaded channel 20 rotatably connected to its input and output ends, respectively. The end of the second auxiliary hose 18 is fixedly connected to a second threaded connector that matches the second threaded channel 19. The drive component also includes a first hose 3 installed at the gas delivery end of the piston chamber 2. One end of the first hose 3 is fixedly connected to a third threaded connector that matches the third threaded channel 20. The I-shaped piston rod 21 consists of two piston plates and a cylindrical connecting rod, and the first hose 3 is disposed between the two piston plates.

[0037] Rubber pads are provided at the contact points of the first threaded channel 16 and the first threaded connector, the second threaded channel 19 and the second threaded connector, and the third threaded channel 20 and the third threaded connector.

[0038] The Velcro has a hook side and a loop side, and the inner and outer sides of the elastic band 1 are respectively provided with a hook side and a loop side;

[0039] There is a gap between the first airbag 9 and the fourth airbag 28;

[0040] When medical staff need to apply pressure to stop bleeding at the patient's incision, they first align the center of the third airbag 15 with the center of the incision. Then, they pull both ends of the elastic band 1 to the patient's back and fix it by attaching the rough and hook surfaces. At this time, the medical staff connect the first threaded channel 16 and the first threaded connector, the second threaded channel 19 and the second threaded connector, and the third threaded channel 20 and the third threaded connector in sequence and fix them with threads. Then, the medical staff press the first airbag 9 and simultaneously press the fourth airbag 28 inside the first airbag 9. After the first press is completed, the gas inside the first airbag 9 enters the second auxiliary hose 18 and is delivered into the inside of the first hose 3 through the second one-way valve 11. The gas pushes the I-shaped piston rod 21 to move towards the elastic band 1, thereby driving the first connecting rod 4 and the second connecting rod 5 to press down, causing the inner edges of the two compression plates 8 to lift up and form an inclination, thereby limiting the two sides of the third airbag 15 and laying the foundation for subsequent pressure hemostasis operations.

[0041] The compressed gas in the fourth airbag 28 enters the third one-way valve 13 and then flows through the second hose 7 into the third airbag 15. At this point, the fourth airbag 28 rebounds, simultaneously pushing the first airbag 9, which is pressed against the outer wall of the fourth airbag 28 (because the second one-way valve 11 is a one-way valve, the gas inside the first airbag 9 is squeezed out after it is pressed, completely adhering to the outer wall of the fourth airbag 28). External gas then enters the first one-way valve 10 and then the fourth airbag 28. Medical staff then repeat this process repeatedly. Press the first airbag 9 to inflate the third airbag 15 until the patient feels appropriate pressure on the incision. Then stop pressing and move the first airbag 9 away from the patient. Because the inner edge of the compression plate 8 is raised, it limits the two sides of the third airbag 15. After the third airbag 15 is inflated, the compression plate 8 limits the third airbag 15 so that it can compress the patient from the vertical direction to stop bleeding. The two compression plates 8 can also form a relative clamping force on the two sides of the third airbag 15 to compress from both sides of the incision.

[0042] The aforementioned third airbag 15 makes flexible contact with the wound surface, without sharp edges or hard points, which can avoid friction and tearing of sutured wounds and broken skin, protect the integrity of the wound, and avoid skin ulceration and nerve damage caused by excessive local pressure (such as the risk of "local pressure sores" of traditional tourniquets). In addition, the third airbag 15 can expand and conform to the curvature of the human body by inflation, solving the problem of "poor fit and pressure dead angle" of rigid compression, thereby improving the recovery effect of the incision after cesarean section.

[0043] The compression plates 8 on both sides of the third airbag 15 "gather" the two sides of the third airbag 15 to the edge of the incision, reducing the tension on the incision caused by patient activities (such as turning over and limb extension), reducing the risk of wound dehiscence, and are especially suitable for hemostasis care in the early postoperative period (when the wound has not healed). The relative force generated by the compression plates 8 is flexibly transmitted through the third airbag 15 (non-rigid compression), avoiding direct contact with the incision or surrounding skin, reducing skin redness and swelling caused by mechanical friction and compression, improving the safety of nursing care, and thus improving the recovery effect of the incision after cesarean section.

[0044] like Figures 2 to 9 As shown, the adjustment unit is located at the end of the elastic band 1 and is used to adjust the pressure of the third airbag 15. The adjustment unit includes a second airbag 14 disposed on the outer wall of the elastic band 1. Two sets of limiting bands 27 are fixedly connected to the inner side of the second airbag 14. An annular band 12 is disposed on the inner side of each of the two sets of limiting bands 27. The annular band 12 is sleeved on the outer wall of the elastic band 1. The adjustment unit also includes a third flexible tube 22 slidably connected inside the elastic band 1. The two ends of the third flexible tube 22 extend to the outside of the elastic band 1, and the two ends of the third flexible tube 22 are installed at the air supply ends of the second airbag 14 and the third airbag 15.

[0045] Before the hook and loop sides of the elastic band 1 are attached and fixed, medical staff can adjust the position of the second airbag 14 according to the position of the patient's waist against the bed. If the second airbag 14 is misaligned, it can be pulled directly to slide along the outer wall of the elastic band 1 through the two annular straps 12 until the center of the second airbag 14 coincides with the center of the patient's waist. After the third airbag 15 is fully inflated and attached to the incision, the patient can adjust their position when they want to lie on their side. At this time, the second airbag 14 is released from restraint. Because the abdominal muscles bulge when the patient lies on their side, the abdominal muscles will compress the third airbag 15, resulting in increased pressure on the incision. At this time, the gas in the third airbag 15 flows into the second airbag 14 through the third flexible tube 22, realizing the adaptive reduction of the internal air pressure of the third airbag 15. After the patient returns to a supine position, the compression between the lower back and the bed pushes the gas in the second airbag 14 back to the third airbag 15, restoring its initial pressure. This prevents the pressure in the third airbag 15 from exceeding the optimal hemostasis range due to positional compression (too high pressure can easily lead to tissue ischemia and pressure sores, while too low pressure will result in hemostasis failure). The "effective hemostasis pressure threshold" at the incision site is always maintained. When the patient returns to a supine position, the gas flows back to the third airbag 15, quickly restoring the initial pressure. This prevents the pressure in the third airbag 15 from dropping sharply due to the loss of abdominal muscle compression after lying down, thus preventing recurrent bleeding. As a result, whether the patient is lying supine or on their side, the hemostasis pressure is always in a balance between "effective hemostasis and tissue safety," achieving "static hemostasis effect under dynamic position" and improving the recovery effect of the cesarean section incision.

[0046] When the patient no longer needs the device, medical staff can directly tear off the rough surface and then disassemble the third one-way valve 13 and the second one-way valve 11. After the second one-way valve 11 is disassembled, external air enters the piston chamber 2, so that the negative pressure inside the piston chamber 2 is no longer generated. Under the action of the rebound spring 23, the I-shaped piston rod 21 is driven to return to its original position, and the first airbag 9 rebounds and inflates by drawing in air. Then the medical staff disinfects the device for the next use.

[0047] The working process provided by the technical solution of this invention is as follows;

[0048] Rubber pads are provided at the contact points of the first threaded channel 16 and the first threaded connector, the second threaded channel 19 and the second threaded connector, and the third threaded channel 20 and the third threaded connector.

[0049] The Velcro has a hook side and a loop side, and the inner and outer sides of the elastic band 1 are respectively provided with a hook side and a loop side;

[0050] There is a gap between the first airbag 9 and the fourth airbag 28;

[0051] When medical staff need to apply pressure to stop bleeding at the patient's incision, they first align the center of the third airbag 15 with the center of the incision. Then, they pull both ends of the elastic band 1 to the patient's back and fix it by attaching the rough and hook surfaces. At this time, the medical staff connect the first threaded channel 16 and the first threaded connector, the second threaded channel 19 and the second threaded connector, and the third threaded channel 20 and the third threaded connector in sequence and fix them with threads. Then, the medical staff press the first airbag 9 and simultaneously press the fourth airbag 28 inside the first airbag 9. After the first press is completed, the gas inside the first airbag 9 enters the second auxiliary hose 18 and is delivered into the inside of the first hose 3 through the second one-way valve 11. The gas pushes the I-shaped piston rod 21 to move towards the elastic band 1, thereby driving the first connecting rod 4 and the second connecting rod 5 to press down, causing the inner edges of the two compression plates 8 to lift up and form an inclination, thereby limiting the two sides of the third airbag 15 and laying the foundation for subsequent pressure hemostasis operations.

[0052] The compressed gas in the fourth airbag 28 enters the third one-way valve 13 and then flows through the second hose 7 into the third airbag 15. At this point, the fourth airbag 28 rebounds, simultaneously pushing the first airbag 9, which is pressed against the outer wall of the fourth airbag 28 (because the second one-way valve 11 is a one-way valve, the gas inside the first airbag 9 is squeezed out after it is pressed, completely adhering to the outer wall of the fourth airbag 28). External gas then enters the first one-way valve 10 and then the fourth airbag 28. Medical staff then repeat this process repeatedly. Press the first airbag 9 to inflate the third airbag 15 until the patient feels appropriate pressure on the incision. Then stop pressing and move the first airbag 9 away from the patient. Because the inner edge of the compression plate 8 is raised, it limits the two sides of the third airbag 15. After the third airbag 15 is inflated, the compression plate 8 limits the third airbag 15 so that it can compress the patient from the vertical direction to stop bleeding. The two compression plates 8 can also form a relative clamping force on the two sides of the third airbag 15 to compress from both sides of the incision.

[0053] The aforementioned third airbag 15 makes flexible contact with the wound surface, without sharp edges or hard points, which can avoid friction and tearing of sutured wounds and broken skin, protect the integrity of the wound, and avoid skin ulceration and nerve damage caused by excessive local pressure (such as the risk of "local pressure sores" of traditional tourniquets). In addition, the third airbag 15 can expand and conform to the curvature of the human body by inflation, solving the problem of "poor fit and pressure dead angle" of rigid compression, thereby improving the recovery effect of the incision after cesarean section.

[0054] The compression plates 8 on both sides of the third airbag 15 "gather" the two sides of the third airbag 15 to the edge of the incision, reducing the tension on the incision caused by the patient's activities (such as turning over and stretching limbs), reducing the risk of the suture wound dehiscence, and are especially suitable for hemostasis care in the early postoperative period (when the wound has not healed). The relative force generated by the compression plates 8 is transmitted flexibly through the third airbag 15 (non-rigid compression), avoiding direct contact with the incision or surrounding skin, reducing skin redness and swelling caused by mechanical friction and compression, improving the safety of nursing care, and thus improving the recovery effect of the incision after cesarean section.

[0055] Before the hook and loop sides of the elastic band 1 are attached and fixed, medical staff can adjust the position of the second airbag 14 according to the position of the patient's waist against the bed. If the second airbag 14 is misaligned, it can be pulled directly to slide along the outer wall of the elastic band 1 through the two annular straps 12 until the center of the second airbag 14 coincides with the center of the patient's waist. After the third airbag 15 is fully inflated and attached to the incision, the patient can adjust their position when they want to lie on their side. At this time, the second airbag 14 is released from restraint. Because the abdominal muscles bulge when the patient lies on their side, the abdominal muscles will compress the third airbag 15, resulting in increased pressure on the incision. At this time, the gas in the third airbag 15 flows into the second airbag 14 through the third flexible tube 22, realizing the adaptive reduction of the internal air pressure of the third airbag 15. After the patient returns to a supine position, the compression between the lower back and the bed pushes the gas in the second airbag 14 back to the third airbag 15, restoring its initial pressure. This prevents the pressure in the third airbag 15 from exceeding the optimal hemostasis range due to positional compression (too high pressure can easily lead to tissue ischemia and pressure sores, while too low pressure will result in hemostasis failure). The "effective hemostasis pressure threshold" at the incision site is always maintained. When the patient returns to a supine position, the gas flows back to the third airbag 15, quickly restoring the initial pressure. This prevents the pressure in the third airbag 15 from dropping sharply due to the loss of abdominal muscle compression after lying down, thus preventing recurrent bleeding. As a result, whether the patient is lying supine or on their side, the hemostasis pressure is always in a balance between "effective hemostasis and tissue safety," achieving "static hemostasis effect under dynamic position" and improving the recovery effect of the cesarean section incision.

[0056] When the patient no longer needs the device, medical staff can directly tear off the rough surface and then disassemble the third one-way valve 13 and the second one-way valve 11. After the second one-way valve 11 is disassembled, external air enters the piston chamber 2, so that the negative pressure inside the piston chamber 2 is no longer generated. Under the action of the rebound spring 23, the I-shaped piston rod 21 is driven to return to its original position, and the first airbag 9 rebounds and inflates by drawing in air. Then the medical staff disinfects the device for the next use.

[0057] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
