[0002] Traditional medical dressings typically consist of an outer membrane made of medical tape or an adhesive film, and a core structure made of gauze, cotton balls, etc., in the center of the outer membrane. They are medical materials used to cover wounds and prevent wound infection.
[0003] Currently, traditional medical dressings often cannot fully meet the requirements for covering different wounds in clinical practice, especially for wounds with fistulas, such as those after the removal of drainage tubes for pleural or peritoneal effusion. After the removal of drainage tubes in the pleural or peritoneal cavity, especially in patients with long-term tube placement, a channel connecting the wound to the pleural or peritoneal cavity will form. If traditional medical dressings are used to cover the wound, fluid from the pleural or peritoneal cavity will usually seep out through the channel, soaking the dressing and causing it to lose its adhesiveness and fail to cover the wound. This not only easily leads to wound infection, but repeated pleural and peritoneal effusion also inconveniences patients' daily lives, requiring frequent dressing changes, which affects wound healing and increases wound care costs.
[0004] Therefore, how to provide a medical balloon pressure dressing that can seal the fistula at the wound site, prevent fluid from seeping out of the fistula, and reduce the risk of wound infection is a technical problem that urgently needs to be solved by those skilled in the art.

[0009] As a further technical solution of this utility model, the water injection valve is a one-way valve.
[0010] A further technical solution of this utility model is as follows: the water injection valve includes: a valve body, the valve body having a cylindrical structure, one end of the valve body being connected to the other end of the water injection conduit, the other end of the valve body being connected to an external water injection device, and the valve body having a water inlet channel; a blocking valve column, the blocking valve column being located inside the other end of the water injection conduit, the side of the blocking valve column near the valve body abutting against one end face of the valve body, the outer diameter of the blocking valve column being larger than the diameter of the water inlet channel and smaller than the inner diameter of the water injection conduit; and an elastic telescopic member, one end of the elastic telescopic member being fixed inside the valve body, and the other end of the elastic telescopic member being perpendicularly connected to the middle of one side of the blocking valve column.

This dressing combines wound-healing and localized pressure application, offering two functions in one. In clinical use, the pressure balloon and infusion catheter are fixed to the patient's wound via the adhesive surface of the dressing, positioning the pressure balloon at the fistula site. Physiological saline is then injected into the pressure balloon through the infusion catheter via an external infusion device and infusion valve, causing the balloon to inflate. The hemispherical surface of the pressure balloon expands downwards, increasing pressure at the wound site. This increased downward pressure seals the fistula, preventing leakage and protecting the dressing from loss of adhesion. This addresses the problem of traditional dressings failing to adhere to wounds with fistulas for extended periods, ensuring effective wound protection and reducing the risk of infection.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example 1
[0035] Please see Figure 1-4This embodiment provides a medical balloon pressure dressing, including a dressing body 1, a pressure balloon 2, a water injection conduit 3, and a water injection valve 4. The dressing body 1 has an adhesive surface and a waterproof surface, which are oppositely distributed. The adhesive surface is made of adhesive material, and the waterproof surface is made of waterproof material. The pressure balloon 2 is made of elastic material and is fixed to the center of the adhesive surface. The pressure balloon 2 has a hemispherical structure, with the hemispherical surface facing away from the adhesive surface. The top surface of the water injection conduit 3 is connected to the adhesive surface, and one end of the water injection conduit 3 is connected to the pressure balloon 2. One end of the water injection valve 4 is connected to the other end of the water injection conduit 3, and the other end of the water injection valve 4 is connected to an external water injection device. The external water injection device contains physiological saline.
[0036] Specifically, this utility model provides a medical balloon pressure dressing, comprising a dressing body 1, a pressure balloon 2, an injection conduit 3, and an injection valve 4. The adhesive surface and waterproof surface of the dressing body 1 are oppositely distributed. The dressing body 1 can be adhered to the wound surface using the adhesive surface made of adhesive material, and the waterproof surface made of waterproof material protects the wound surface. The pressure balloon 2, made of elastic material, is fixed in the middle of the adhesive surface. The pressure balloon 2 has a hemispherical structure, with the hemispherical surface facing away from the adhesive surface. The top surface of the injection conduit 3 is connected to the adhesive surface. One end of the injection conduit 3 is connected to the pressure balloon 2, and the other end is connected to one end of the injection valve 4. The other end of the injection valve 4 is connected to an external injection device. The pressure balloon 2 forms the core of the medical balloon pressure dressing, allowing the dressing to... This dressing serves two purposes: bandaging and applying local pressure. In clinical use, the pressure balloon 2 and the water infusion catheter 3 are fixed to the patient's wound via the adhesive surface of the dressing body 1, positioning the pressure balloon 2 at the fistula opening. Physiological saline is injected into the pressure balloon 2 through the water infusion catheter 3 via an external water infusion device using the water infusion valve 4. This inflates the pressure balloon 2, causing its hemispherical surface to expand downwards, thus increasing the pressure applied to the wound. This increased downward pressure seals the fistula opening, preventing fluid leakage and protecting the dressing from losing adhesion due to leakage. This addresses the problem of traditional dressings failing to adhere to the wound for extended periods when used on wounds with fistulas, ensuring effective wound protection and reducing the risk of infection.
[0037] In some possible implementations, the surface may further include: an easy-tear adhesive label 5, which is adhered to the waterproof surface, and the size of the easy-tear adhesive label 5 is the same as that of the waterproof surface. The easy-tear adhesive label 5 may be made of a plastic film.
[0038] Those skilled in the art will understand that the easy-tear adhesive 5 is bonded to the waterproof surface, and the size of the easy-tear adhesive 5 is the same as the size of the waterproof surface, so that the easy-tear adhesive 5 is placed on the upper surface of the dressing body 1 as an outer protective layer, and plays a role in protecting the dressing body 1 located in the inner layer before the dressing body 1 is used.
[0039] In some possible implementations, it further includes: a release paper 6, which is bonded to the adhesive surface, the size of the release paper 6 being the same as the size of the adhesive surface, and the pressurized balloon 2 and the water injection conduit 3 being located between the release paper 6 and the adhesive surface.
[0040] Those skilled in the art will understand that the release paper 6 is bonded to the adhesive surface, and the size of the release paper 6 is the same as that of the adhesive surface. The release paper 6 can be used as an inner protective layer on the lower surface of the dressing body 1 to protect the dressing body 1. It also protects the pressure balloon 2 and the water injection conduit 3 located between the release paper 6 and the adhesive surface. Furthermore, the water injection valve 4 is located outside the space between the release paper 6 and the adhesive surface, facilitating connection of the water injection valve 4 to external water injection equipment.
[0041] In some possible implementations, the water injection valve 4 is a one-way valve.
[0042] This is because the water injection valve 4 is a one-way valve. When the external water injection device injects saline into the water injection tube 3 through the water injection valve 4, causing the pressure balloon 2 to inflate, the one-way valve can block the backflow of saline in the pressure balloon 2, thereby maintaining the inflation state of the pressure balloon 2 and continuously sealing the fistula at the wound.
[0043] In some possible embodiments, the water injection valve 4 includes: a valve body 41, which is cylindrical in shape, with one end connected to the other end of the water injection conduit 3, and the other end connected to an external water injection device; a water inlet channel inside the valve body 41; a blocking valve column 42, located inside the other end of the water injection conduit 3, with one side of the blocking valve column 42 near the valve body 41 abutting against one end face of the valve body 41; the outer diameter of the blocking valve column 42 being larger than the diameter of the water inlet channel and smaller than the inner diameter of the water injection conduit 3; and the blocking valve column 42 being used to close or open the water inlet channel; and an elastic telescopic member 43, one end of which is fixed inside the valve body 41, and the other end of which is perpendicularly connected to the middle of one side of the blocking valve column 41.
[0044] This is because one end of the cylindrical valve body 1 is connected to the other end of the water injection conduit 3, and the other end is connected to an external water injection device, so as to connect the water inlet channel inside the valve body 41 with the water injection conduit 3 and the external water injection device; the sealing valve column 42 located inside the other end of the water injection conduit 3 abuts against the end face of the valve body 41 on one side near the valve body 41. The outer diameter of the sealing valve column 42 is larger than the diameter of the water inlet channel and smaller than the inner diameter of the water injection conduit 3, so that the water inlet channel is closed by the sealing valve column 42 abutting against the end face of the valve body 41; one end of the elastic telescopic member 43 is fixed inside the valve body 41, and the other end is vertically connected to the middle of the side of the sealing valve column 41. When water is injected into the valve body 1, the water flows from the outside of the other end of the valve body 1. The water inlet pipe 3 flows to one end of the valve body 1. Under water pressure, the sealing valve column 42 moves from the other end of the valve body 1 toward one end of the valve body 1, causing the elastic telescopic member 43 to extend. At this time, the sealing valve column 42 no longer abuts against one end face of the valve body 41, thus opening the water inlet channel. The water flows through the water inlet channel and the water inlet pipe 3 into the pressure balloon 2. When the water injection stops, the elastic telescopic member 43 contracts and returns to its original position under the action of elasticity. At the same time, it moves the sealing valve column 42 from one end of the valve body 1 toward the other end of the valve body 1 to reset, thus abutting against one end face of the valve body 41 to close the water inlet channel, thereby blocking the backflow of saline in the pressure balloon 2, thereby maintaining the inflated state of the pressure balloon 2 to continuously seal the fistula at the wound.
[0045] In some possible implementations, the elastic telescopic member 43 includes: a fixed rod 431, both ends of which are fixed to the inner wall of the valve body 41, and the fixed rod 431 is arranged in a direction perpendicular to the central axis of the valve body 41; a sleeve 432, one end of which is perpendicularly connected to the middle of the fixed rod 431; a push rod 433, one end of which is perpendicularly connected to the middle of one side of the blocking valve column 42, and the other end of which is movably disposed inside the other end of the sleeve 432; and a spring 434, located inside the sleeve 432, one end of which is fixedly connected to the middle of the fixed rod 431, and the other end of which is fixedly connected to the other end of the push rod 433.
[0046] This is because the two ends of the fixing rod 431, which is arranged along a direction perpendicular to the central axis of the valve body 41, are fixed to the inner wall of the valve body 41. One end of the sleeve 432 is perpendicularly connected to the middle of the fixing rod 431, so as to fix one end of the sleeve 432 inside the valve body 41 and make the sleeve 432 arranged along the central axis of the valve body 41. One end of the push rod 433 is perpendicularly connected to the middle of one side of the sealing valve column 42, and the other end is movably arranged inside the other end of the sleeve 432. One end of the spring 434 located inside the sleeve 432 is fixedly connected to the middle of the fixing rod 431, and the other end is fixedly connected to the push rod 433. The other end of the rod 433 is fixedly connected. When the sealing valve column 42 moves from the other end of the valve body 1 toward one end of the valve body 1 under the action of water pressure, it can drive the push rod 433 to move from the other end of the valve body 1 toward one end of the valve body 1. This causes the spring 434 at the other end of the push rod 433 to be stretched. When the water injection stops, the spring 434 contracts and returns to its original state under the action of elasticity, so as to drive the push rod 433 to move and reset from one end of the valve body 1 toward the other end of the valve body 1. This, in turn, drives the sealing valve column 42 to move and reset to abut against one end face of the valve body 41 to close the water inlet channel.
[0047] In some possible implementations, the pressure balloon 2 is made of medical rubber material, and the waterproof surface is made of waterproof PU film.
[0048] Those skilled in the art will understand that the pressure balloon 2 is made of medical rubber material, which gives the pressure balloon 2 a certain degree of elasticity and allows it to be inflated with water; the waterproof surface is made of waterproof PU film, which gives the waterproof surface a certain degree of waterproofness and can protect the wound.
[0049] In some possible implementations, a first tear-opening 7 is provided in the middle of the easy-tear sticker 5 along the width direction of the easy-tear sticker 5, which makes it easy to tear the easy-tear sticker 5 and facilitates operation.
[0050] In some possible implementations, the end of the release paper 6 is provided with a second easy-tear opening 8, through which the release paper 6 can be easily torn apart, making the operation convenient.
[0051] In some possible implementations, the water injection conduit 3 has a flat structure.
[0052] Those skilled in the art will understand that the water injection catheter 3 has a flat structure. When the water injection catheter 3 is attached to the wound surface through the dressing body 1, the flat structure makes it easy for the upper and lower surfaces of the water injection catheter 3 to fit with the dressing body 1 and the wound surface respectively, thereby enhancing the connection stability.
[0053] In clinical use, the medical balloon pressure dressing of this invention is first used by tearing open the innermost release paper 6 along the second easy-tear opening 8 to expose the adhesive surface of the dressing body 1. The uninflated pressure balloon 2, located at the dressing core on the adhesive surface, is then aligned with the fistula at the wound site. Simultaneously, the dressing body 1 is placed over the wound, and the adhesive surface of the dressing body 1 is used to fix the dressing to the wound. At this point, the fistula should be directly below the dressing core (pressure balloon 2). Next, the easy-tear patch 5 is torn open along the first easy-tear opening 7 and removed from the waterproof surface. The dressing body 1 is then pressed and smoothed to ensure a more complete fit to the wound. Finally, saline solution is injected into the pressure balloon 2 using the water injection valve 4, causing the pressure balloon 2 to inflate. The inflated pressure balloon 2 compresses the fistula at the wound site, thereby blocking the leakage of body fluid from the fistula.
[0054] Furthermore, the medical balloon pressure dressing of this invention is made of common materials, is easy to process, and features a simple and ingenious design of the pressure balloon, making it highly feasible and possessing broad potential for clinical application. Besides being particularly suitable for extubation wounds after pleural or peritoneal effusion catheterization, it also has potential value for other easily exudative wounds. For example, for patients with poor coagulation function, after venous blood collection or intravenous infusion, the injection site is prone to continuous bleeding, requiring prolonged pressure with cotton swabs for hemostasis. For these patients, the medical balloon pressure dressing can replace manual cotton swab pressure for hemostasis, increasing patient convenience while being safer and more reliable.
