Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a pressure bandaging and fixation device for postoperative wound treatment of vulvar cancer. Background Technology

[0002] Vulvar cancer is a relatively rare malignant tumor of the female reproductive system, which mainly occurs in the skin and mucous membranes of the vulva. In order to protect the surgical wound, reduce local tension, prevent hematoma or seroma formation, and promote healing, pressure bandages are used to fix the vulvar wound. Commonly used fixation devices include medical bandages, custom-made pressure devices, and medical fixation straps.

[0003] For example, Chinese utility model patent CN217907885U discloses a pressure bandage fixation structure for postoperative wound treatment of vulvar cancer. This device uses a loose-fitting waistband with a locking edge and an elastic adjustment mechanism, allowing patients to adjust the fixation according to their waist circumference and tolerance. The thickened bottom of the fixation pants can provide pressure hemostasis. The Velcro design at the front of the perineum allows for the connection and fixation of the pressure hemostatic material according to the patient's individual body shape and postoperative condition, and can also be adjusted.

[0004] Existing pressure bandage fixation structures for postoperative vulvar cancer treatment achieve hemostasis by thickening the bottom of the fixation pants. However, in actual application, the thickness of the bottom of the fixation pants cannot be adjusted, resulting in a lack of flexibility in adjusting the pressure on the wound site. During postoperative recovery, excessive pressure may lead to ischemic necrosis of the skin, especially in diabetic patients or those with poor vascular conditions. Therefore, there are certain limitations in the scope of application in actual use. Summary of the Invention

[0014] Optionally, a partition is fixedly connected to the inner surface of the detection cover, and an overflow groove is embedded in the inner side of the absorbent cotton. One end of the overflow groove extends through the inner side of the detection cover, and the other end is connected to the inside of the drainage hole. The drainage groove is in several groups and its lower end is staggered with the partition. The detection cover is made of transparent material.

[0015] Optionally, the absorbent cotton is provided with a binding assembly on its outer side. The binding assembly includes an ear piece fixedly connected to the outer surface of the absorbent cotton. An adhesive tape is fixedly connected to the upper outer surface of the ear piece. The lower outer surface of the absorbent cotton is embedded with a movable groove and a folding groove. The number of movable grooves and folding grooves are several sets and they are distributed in a parallel array.

[0016] Optionally, the absorbent cotton has an embedded cavity on its inner side, and a slot is embedded on the inner surface of the cavity. A locking block is engaged with the inner side of the slot, and a roller is fixedly connected to the outer surface of the locking block. The roller extends through to the outside of the absorbent cotton and is rotatably connected to the absorbent cotton. An ear plate is fixedly connected to the side of the roller away from the locking block. A slot is formed through the outer surface of the roller. An elastic band is fixedly connected to the inner surface of the cavity, and the elastic band passes through the slot and extends through both ends of the roller.

[0017] Optionally, an infusion assembly is provided on the outside of the absorbent cotton. The infusion assembly includes a telescopic tube fixedly connected to the upper outer surface of the absorbent cotton. A telescopic groove is embedded in the outer surface of the telescopic tube. A clamp is fixedly connected to the inner surface of the telescopic tube. An expansion plate is fixedly connected to the lower surface of the clamp. The number of expansion plates and clamps are several sets and they are arranged in a ring array. A liquid guide tube is engaged with the outer surface of the clamp.

[0019] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0020] In the above solution, by setting up a pressure component and coating the upper side of the contact piece with an antibacterial coating, it can effectively exert an antibacterial effect on the area around the wound, thereby preventing the risk of inflammation and infection of the vulvar wound. By flexibly adjusting the volume of the expansion sleeve, the pressure applied to the vulvar wound can be effectively adjusted, ensuring the hemostatic care effect while also reducing discomfort during the use of the care device to a certain extent.

[0021] This solution, by setting up a drainage component, allows for the assessment of the amount of secretions stored inside the drainage hole by observing the secretions inside the detection cover. This enables the selection of the appropriate time to drain the secretions, thereby effectively improving the convenience of using the nursing device. The secretions flow through the notch on the surface of the drainage tube into the drainage tube, thus allowing the secretions to be drained to the outside of the dressing device in a timely manner, further reducing the risk of wound infection.

[0022] This solution incorporates a buffer component. When the patient accidentally pulls on the buffer tube during turning over or other unexpected activities, the downward movement of the buffer tube and the deformation of the buffer sleeve can cushion the pulling force. This reduces the force transmitted to the vulva and bladder, thereby decreasing urethral pain and damage caused by accidental pulling of the buffer tube and improving the safety and reliability of the fixation device.

[0036] 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.

[0037] like Figures 1 to 11 As shown, an embodiment of the present invention provides a pressure bandaging and fixation device for postoperative vulvar cancer surgery, including absorbent cotton 11, with an air guide groove 13 extending through the upper outer surface of the absorbent cotton 11, and a pressure component disposed on the upper side of the absorbent cotton 11. Figure 10 As shown, the pressurizing assembly includes an annular groove 40 embedded in the outer surface of the upper end of the absorbent cotton 11. An expansion sleeve 12 for pressurizing and fixing the vulva is fixedly connected to the outer surface of the upper end of the absorbent cotton 11. The annular groove 40 is located inside the expansion sleeve 12. The expansion sleeve 12 is made of elastic silicone material and is elliptical in shape. The outer surface of the upper end of the expansion sleeve 12 is inclined. A contact piece 43 is fixedly connected to the outer surface of the upper end of the absorbent cotton 11. The contact piece 43 is located inside the expansion sleeve 12 and is made of breathable material. The upper surface of the contact piece 43 is coated with an antibacterial coating. Figure 4 As shown, an adjusting tube 53 is embedded inside the absorbent cotton 11. The adjusting tube 53 is connected to the inside of the circulation groove 40, and a control valve for controlling gas flow is installed inside the adjusting tube 53. Figure 11 As shown, the sealing assembly includes a sealing block 47, a drainage hole 45 extending through the inner side of the absorbent cotton 11, a sealing block 47 fixedly connected to the inner surface of the drainage hole 45, and a sealing seat 51 slidably connected to the inner side of the drainage hole 45. Figure 9 As shown, a display component is provided inside the absorbent cotton 11. The display component includes a detection cover 37 fixedly connected to the outer surface of the lower end of the absorbent cotton 11. A partition 38 is fixedly connected to the inner surface of the detection cover 37. An overflow groove 39 is embedded inside the absorbent cotton 11.

[0038] By adopting the above technical solution, when using the pressure bandaging and fixation device, firstly, the absorbent cotton 11 is placed on the inner thigh, and the expansion sleeve 12 is aligned with the vulvar wound. Then, the absorbent cotton 11 is tied and fixed to ensure the stable position of the absorbent cotton 11 and the expansion sleeve 12. The elliptical distribution of the expansion sleeve 12 can apply pressure evenly to the vulva, thereby ensuring a tight fit between the expansion sleeve 12 and the vulvar skin, thus achieving a pressure-based hemostatic effect on the vulvar wound. The contact plate on the upper side of the absorbent cotton 11 contacts the inner side of the vulva. By coating the upper side of the contact plate 43 with an antibacterial coating, it can effectively provide antibacterial protection around the wound, preventing the risk of inflammatory infection of the vulvar wound.

[0039] In this embodiment, the bandaging and fixation device incorporates a pressurizing component to maintain the pressure between the expansion sleeve 12 and the vulva within an appropriate range during use. The user connects the syringe to the regulating tube 53 and injects air into it via a control valve. As the gas is gradually injected, it flows within the circulation groove 40. As the gas pressure increases, the volume of the expansion sleeve 12 also increases, thereby increasing the pressure between the expansion sleeve 12 and the vulva. This embodiment allows for flexible adjustment of the volume of the expansion sleeve 12, effectively adjusting the pressure applied to the vulvar wound. This ensures hemostasis and reduces discomfort during use. The drainage holes 45 on the surface of the absorbent cotton 11 are used to drain secretions. When the sealing seat 51 and sealing block 47 seal the drainage holes 45, as the secretions inside the drainage holes 45 gradually increase, they flow through different overflow grooves 39 into the detection cover 37. By observing the secretions inside the detection cover 37, the amount of secretions stored in the drainage holes 45 can be determined.

[0040] like Figure 4 , Figure 10 and Figure 11 As shown, a drainage component is provided on the inner side of the absorbent cotton 11. The drainage component includes a guide groove 42 opened between the contact piece 43 and the absorbent cotton 11. A baffle 41 is fixedly connected to the inner surface of the guide groove 42. Both the guide groove 42 and the baffle 41 are elliptical. A through groove 44 is opened through the inner side of the contact piece 43. The two ends of the through groove 44 are connected to the inside of the guide groove 42.

[0041] By adopting the above technical solution, when the wound dressing and fixation device is in use, secretions may seep from the patient's wound and genitals. To reduce the risk of wound infection caused by these secretions, a drainage component is installed. The outer surface of the expansion sleeve 12 is inclined to guide the secretions, allowing them to move towards the baffle 41 in a timely manner. The secretions then flow from the gap between the baffle 41 and the absorbent cotton 11 into the drainage channel 42. The drainage channel 42 and the through channel 44 can store and collect the secretions. The baffle 41 can prevent the backflow of secretions to a certain extent. By timely draining the secretions, the risk of wound infection can be effectively reduced, thereby further improving the safety of the wound care device during use.

[0042] like Figure 4 , Figure 10 and Figure 11 As shown, the lower end of the drainage hole 45 extends to the lower side of the absorbent cotton 11. The guide groove 42, the through groove 44, and the drainage hole 45 are connected. The sealing blocks 47 are distributed in a ring shape and are made of elastic material. A traction belt 50 is fixedly connected between the sealing block 47 and the sealing seat 51. A guide ring 48 is fixedly connected to the inner surface of the sealing block 47. A cavity 52 is opened through the inner side of the sealing seat 51. There are two sets of traction belts 50, which are symmetrically distributed and are made of elastic material. A drainage tube 46 (e.g., ...) is slidably connected to the inner surface of the sealing ring 33. Figure 8 As shown), a notch 49 is provided through the upper side of the outer surface of the drainage tube 46. The notches 49 are in several groups and are distributed in a ring array. The upper end of the drainage tube 46 is in contact with the lower outer surface of the sealing seat 51.

[0043] By adopting the above technical solution, the drainage hole 45 is used to fix and support the sealing block 47, and the sealing seat 51 fits against the outside of the sealing block 47 to seal the inside of the drainage hole 45, thereby preventing leakage of secretions. When a certain amount of secretions are stored inside the drainage groove 42, the operator inserts the drainage tube 46 into the drainage hole 45. The upper end of the drainage tube 46 will contact the lower surface of the sealing seat 51, and the sealing seat 51 will move upward under the push of the drainage tube 46. At this time, the secretions inside the drainage hole 45 will flow downward from between the sealing seat 51 and the sealing block 47. The secretions flow into the inside of the drainage tube 46 through the notch 49 on the surface of the drainage tube 46, thereby timely draining the secretions to the outside of the bandaging device, thereby further reducing the risk of wound infection. After the secretions are discharged, the operator removes the drainage tube 46. At this time, the sealing seat 51 moves in the opposite direction under the elastic force of the traction strap 50, so that the sealing seat 51 and the outer surface of the sealing block 47 are in contact to seal the inside of the drainage hole 45. The cavity 52 inside the sealing seat 51 can reduce the weight of the device to a certain extent, thereby improving the comfort during the wearing process.

[0044] like Figure 4 and Figure 9 As shown, one end of the overflow channel 39 extends through the inside of the detection cover 37, and the other end connects to the inside of the drainage hole 45. Several sets of drainage channels are arranged, with their lower ends staggered with the partition 38. The detection cover 37 is made of transparent material. By adopting the above technical solution, the overflow channel 39 inside the absorbent cotton 11 is connected to both the detection cover 37 and the drainage hole 45. When secretions are present inside the drainage hole 45, they will enter the detection chamber through the overflow channel 39. The partition 38 divides the internal space of the detection chamber, allowing for the selection of an appropriate time to drain the secretions, thereby effectively improving the convenience of using the nursing device.

[0045] like Figure 1 As shown, the absorbent cotton 11 has a binding assembly on its outer side. The binding assembly includes ear pieces 16 fixedly connected to the outer surface of the absorbent cotton 11. An adhesive tape 15 is fixedly connected to the upper outer surface of the ear pieces 16. The lower outer surface of the absorbent cotton 11 has embedded movable grooves 18 and folding grooves 14. The number of movable grooves 18 and folding grooves 14 are several sets and they are distributed in a parallel array. By adopting the above technical solution, when the absorbent cotton 11 is bound, the ear pieces 16 and the adhesive tape 15 can quickly fix the absorbent cotton 11. At this time, the left and right ends of the absorbent cotton 11 will wrap around the patient's waist, so that the position of the absorbent cotton 11 remains stable. The movable grooves 18 and folding grooves 14 on the surface of the absorbent cotton 11 can reduce the deformation resistance to a certain extent, so that the absorbent cotton 11 fits more closely to the patient's skin surface, thereby further improving the wearing effect.

[0046] like Figure 6As shown, an inner cavity 25 is embedded in the absorbent cotton 11. A slot 26 is embedded in the inner surface of the cavity 25, and a locking block 29 is engaged within the slot 26. A scroll 27 is fixedly connected to the outer surface of the locking block 29. The scroll 27 extends through to the outside of the absorbent cotton 11 and is rotatably connected to it. An ear plate 30 is fixedly connected to the side of the scroll 27 away from the locking block 29. A slot 31 is formed through the outer surface of the scroll 27. An elastic band 28 is fixedly connected to the inner surface of the cavity 25, passing through the slot 31 and extending to both ends of the scroll 27. By adopting the above technical solution, during the use of the wound fixation device, the elastic band 28 inside the cavity 25 can maintain a certain tension on the absorbent cotton 11, allowing for adjustment of the tightness of the absorbent cotton 11 according to the patient's body shape. When adjusting the tightness, the operator first pulls the roller 27 outward through the ear plate 30. The roller 27 causes the locking block 29 to disengage from the locking groove 26. Both the locking block 29 and the locking groove 26 are rectangular structures. Then, the operator rotates the roller 27 through the ear plate 30. The elastic band 28 passes through the slot 31 on the surface of the roller 27. As the roller 27 rotates, the elastic band 28 can be wound around the outside of the roller 27, thereby partially winding up the elastic band 28. This can improve the tightness of the absorbent cotton 11 to a certain extent, which helps to improve the adaptability and flexibility of the wound fixation device during use.

[0047] like Figure 7 As shown, an infusion assembly is provided on the outside of the absorbent cotton 11. The infusion assembly includes a telescopic tube 19 fixedly connected to the upper outer surface of the absorbent cotton 11. A telescopic groove 20 is embedded in the outer surface of the telescopic tube 19. A clamp 22 is fixedly connected to the inner surface of the telescopic tube 19. An expansion plate 23 is fixedly connected to the lower surface of the clamp 22. The number of expansion plates 23 and clamps 22 are several sets and arranged in a ring array. A drainage tube 21 is engaged with the outer surface of the clamp 22. A stop block 24 is fixedly connected to the lower side of the outer surface of the drainage tube 21. By adopting the above technical solution, patients after vulvar surgery often need to use a urinary catheter to drain urine in a timely manner to reduce the risk of wound contamination during urination. In order to further improve the installation stability of the urinary catheter, an infusion assembly is set up. The upper end of the infusion tube 21 is connected to the urinary catheter to drain urine from the bladder. The lower end of the infusion tube is engaged with the telescopic tube 19. The telescopic groove 20 on the surface of the telescopic tube 19 can adjust the length of the telescopic tube 19. The telescopic tube 19 applies a certain compression plate to the clamp 22 through the expansion plate 23. The ring-shaped clamp 22 can clamp and fix the infusion tube 21, thereby keeping the position of the infusion tube 21 stable. The stop block 24 on the lower side of the infusion tube 21, together with the clamp 22, can limit the position of the infusion tube 21, thereby further improving the stability of the infusion tube 21. By setting the urinary catheter in segments, the ease of wearing the wound fixation device can be reduced to a certain extent.

[0048] like Figure 8 As shown, a support tube 32 is fixedly connected to the lower outer surface of the absorbent cotton 11. A buffer groove 35 is embedded in the inner side of the support tube 32. A guide tube 34 is slidably connected to the inner side of the buffer groove 35. A buffer tube 17 is fixedly connected to the lower end of the guide tube 34. A buffer sleeve 36 is fixedly connected to the upper outer surface of the upper end of the guide tube 34. The upper end of the buffer sleeve 36 is fixedly connected to the upper side of the inner surface of the buffer groove 35. A sealing ring 33 is fixedly connected to the inner surface of the support tube 32. The sealing ring 33 is in sliding contact with the outer side of the buffer tube 17.

[0049] By adopting the above technical solution, the support tube 32 on the lower side of the absorbent cotton 11 can protect the buffer tube 17. The lower end of the buffer tube 17 is connected to the urine storage bag, and the support tube 32 slides to support the guide tube 34 through the buffer groove 35. When the patient accidentally pulls the buffer tube 17 during turning over or accidental movement, the buffer tube 17 will drive the guide tube 34 to slide downward along the inside of the buffer groove 35 under the action of the pulling force. During the movement, the guide tube 34 will pull the buffer sleeve 36, thereby causing the buffer sleeve 36 to produce a certain degree of elastic deformation. The downward movement of the buffer tube 17 and the deformation of the buffer sleeve 36 can buffer the pulling force, thereby reducing the force transmitted to the vulva and bladder to a certain extent. This can reduce urethral pain and damage caused by accidental pulling of the buffer tube 17, and help improve the safety and reliability of the fixation device. The sealing ring 33 can seal between the buffer tube 17 and the support tube 32 to reduce the risk of urine leakage.

[0050] The working process of the postoperative wound pressure bandaging and fixation device for vulvar cancer provided by this invention is as follows:

[0051] When the bandaging and fixing device is in operation, the ear piece 16, in conjunction with the adhesive tape 15, enables the rapid fixing of the absorbent cotton 11, thereby stabilizing its position. As the roller 27 rotates, the elastic band 28 is wound around its outer side, allowing for partial winding of the elastic band 28 and thus adjusting the tightness of the absorbent cotton 11. The elliptical distribution of the expansion sleeve 12 applies pressure evenly to the vulva, ensuring a close fit between the expansion sleeve 12 and the vulvar skin, thus providing pressure and hemostasis at the vulvar wound. As the gas pressure gradually increases, the volume of the expansion sleeve 12 also increases, thereby increasing the compressive force between the expansion sleeve 12 and the vulva. By flexibly adjusting the volume of the expansion sleeve 12, its inclined outer surface helps to guide secretions.

[0052] The guide groove 42 and through groove 44 can store and collect the sealant. The secretions will enter the detection cover 37 through different overflow grooves 39. By observing the secretions inside the detection cover 37, the amount of secretions stored inside the drainage hole 45 can be judged. When a certain amount of secretions is stored inside the guide groove 42, the drainage tube 46 is inserted into the drainage hole 45. The sealing seat 51 will move upward under the push of the drainage tube 46. The secretions inside the drainage hole 45 will flow downward from between the sealing seat 51 and the sealing block 47. The secretions will flow into the drainage tube 46 through the notch 49 on the surface of the drainage tube 46, so that the secretions can be drained to the outside of the bandaging device in time. The telescopic tube 19 will apply a certain compression plate to the clamping plate 22 through the expansion plate 23. The annularly distributed clamping plate 22 can clamp and fix the liquid guide tube 21, so that the position of the liquid guide tube 21 remains stable. When the patient accidentally pulls on the buffer tube 17 during turning over or other unexpected activities, the buffer tube 17 will cause the guide tube 34 to slide downward along the inside of the buffer groove 35 under the action of the pulling force. During the movement, the guide tube 34 will pull the buffer sleeve 36. The downward movement of the buffer tube 17 and the deformation of the buffer sleeve 36 can buffer the pulling force.

[0053] 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.
