Description

Technical Field

[0001] This invention relates to the field of wound irrigation and leakage prevention, specifically to an adsorption-type wound irrigation blocker. Background Technology

[0002] Postoperative complications such as liquefaction, infection, and dehiscence are common after abdominal incision surgery. Irrigation before suturing can reduce these complications; however, wastewater often spills out of the incision during irrigation, causing contamination. Intraoperative measures are necessary to reduce or prevent this contamination. Commonly used methods include... Figure 1 As shown, the curved part of the "S"-shaped abdominal hook L is used to block the flushing, forming an "S" zone to store wastewater. The arrow indicates the flushing direction. Although this method can be used as a workaround, the effect is not good. After flushing, the waste liquid needs to be absorbed to prevent excessive spillage. The most common problem is that leakage is easy to occur at the skin contact points, causing pollution. For example, on both sides of the abdomen, the body is curved, and if it does not fit well, gaps will appear, which will easily lead to water leakage. Moreover, it is difficult to keep pressing down to make it fit the skin. Therefore, how to achieve leakage prevention of the barrier is an urgent problem for technicians in this field to solve. Summary of the Invention

[0003] The purpose of this invention is to provide an adsorption-type wound irrigation blocker to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adsorption-type wound irrigation baffle, comprising a C-shaped baffle for convenient water collection, the end of which can be bent inwards; of course, it can also be annular, but in practice, a C-shape is sufficient. The baffle is hollow inside, and the lower end of the baffle is open. An elastic latex membrane with an arc-shaped cross-section is provided at the opening to conform to the skin. The latex membrane can conform to the skin and is not prone to leakage. It also includes a dual-absorption mechanism disposed on the latex membrane to simultaneously absorb both the skin and internal liquid, and a liquid-absorbing mechanism installed inside the latex membrane to remove waste liquid. The dual-absorption mechanism mainly adsorbs the skin to fix the latex membrane and prevent it from lifting and leaking water. At the same time, it can also absorb and remove waste liquid. The liquid-absorbing mechanism further removes and discharges the waste liquid brought in by the dual-absorption mechanism. The toughness of the latex film can be adjusted according to its thickness. It should not be too soft because the inside is under negative pressure. The latex film needs to maintain a certain state, just enough to deform and fit the skin when suctioning. Moreover, the amount of deformation does not need to be too large, because the skin itself is soft and the fit is good.

[0005] Preferably, the dual-absorption mechanism includes multiple adsorption holes formed at the bottom of the latex film to adsorb the skin, and the adsorption holes extend inward and upward to form an elongated shape that facilitates the adsorption of waste liquid. For ease of description, the baffle opens to the right, and the suction hole is strip-shaped. The bottom of the hole adheres to the skin, securing the latex membrane. The extension to the right and upwards absorbs horizontally flowing waste liquid. This single hole serves two purposes: it can hold the skin in place and absorb waste liquid. Compared to two separate holes, when no liquid is flowing, it only adheres to the skin, allowing some air to enter, thus reducing pressure and preventing discomfort from excessive suction. When waste liquid is flowing, it absorbs it. When no waste liquid is flowing, the latex membrane around the suction hole deforms and presses down due to negative pressure, increasing the skin contact area for better absorption. Essentially, the suction hole converts the waste liquid absorption portion into a skin absorption portion. When there is a lot of waste liquid, some liquid will flow into the bottom contact portion of the suction hole, effectively converting some space into a liquid absorption portion, increasing the absorption effect. Furthermore, the waste liquid is absorbed more cleanly and thoroughly because the suction hole is in contact with the skin. Therefore, compared to a combination of skin adhesion and waste liquid absorption, this single-hole dual-purpose design not only achieves the function of two holes but is also superior to both, offering greater safety and comfort.

[0006] Preferably, the liquid suction mechanism includes a suction tube located within the latex membrane along its length and a suction hole formed on the suction tube, with a negative pressure tube extending out of the latex membrane connected to the middle of the suction tube. The suction hole can be located at the bottom; of course, the suction tube has a circular cross-section so that the suction hole is not blocked and extends out on both sides.

[0007] Preferably, it also includes a waste liquid backflow prevention mechanism disposed within the latex membrane. This prevents waste liquid from flowing back through the adsorption holes when the negative pressure stops.

[0008] Preferably, the anti-backflow mechanism includes an anti-backflow tube connected to the inner end of the adsorption hole and pointing upwards, with a through hole on its upper side. Since the through hole is located on the upper side and the liquid is at the bottom of the latex film, it will not spill.

[0009] Preferably, the anti-backflow tube is made of the same material as the latex film, and the through hole is formed by an opening so that it can be closed together by elasticity to prevent backflow under normal conditions. The through hole is formed by making a slit or opening in the anti-backflow tube, so that it remains closed under normal conditions and will not leak. To improve stability, the bottom of the anti-backflow tube can be wider.

[0010] Preferably, the upper end of the anti-backflow tube is inclined in an arc shape towards the center of the baffle, with the end of the bend abutting against the inner wall of the side to achieve elastic compression of the through hole, and the through hole is opened on the back of the bend. The elastic force of the bend against the inner wall of the baffle makes the through hole close more tightly, so it is not easily opened during movement, preventing waste liquid from spilling out.

[0011] Preferably, the baffle is made of latex material that can be bent and deformed under force to fit the skin. The wall thickness can be increased to maintain its shape; for example, its hardness can be similar to a belt in a car engine, possessing both rigidity and deformability. The toughness can be determined based on the wall thickness and the specific material.

[0012] Preferably, the upper wall of the inner cavity of the baffle is provided with a support strip that can be bent and deformed under force to support the shape of the baffle. Materials such as aluminum alloy, aluminum, or gooseneck tubing that can maintain their shape after being bent under force can be used.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The latex film is tough and can adhere to the skin. The adsorption holes can adhere to the skin and fix it in place. There is no need to press the baffle with your hands. You only need to hold it. It can also adsorb waste liquid, ensuring the skin fit. It can also remove waste liquid in time to prevent accumulation and spillage.

[0015] 2. When there is less waste liquid, under the negative pressure inside the latex membrane, the adsorption pores deform downward, increasing the contact area with the skin and thus the adsorption area, which improves the adsorption effect. This ensures the tension of the latex membrane between the two adsorption pores and improves the adhesion to the skin. When the amount of waste liquid increases, some of it will flow to the lower side of the adsorption pores. Therefore, the area for adsorbing waste liquid will increase, thus improving the waste liquid absorption effect.

[0016] 3. The baffle is flexible and can conform to the skin. Combined with the latex film, it can adapt to the curves of the body. The support strip on the inner side ensures the stability of the shape after deformation, better conforms to the skin, and prevents leakage. At the same time, the latex film is flexible and comfortable. It conforms to the skin by self-adhesion, so there is no need to press down on the baffle, which saves more effort.

[0017] 4. The adsorption pores can adhere to the skin to achieve a fixed leak-proof effect, and can also adsorb waste liquid. There is no gap between the adsorption pores and the waste liquid on the skin, so the adsorption is more thorough. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 2 to 7 This invention provides a technical solution for an adsorption-type wound irrigation baffle: an adsorption-type wound irrigation baffle includes a C-shaped baffle 1 for easy water collection, the end of which can be bent inwards; of course, it can also be ring-shaped, but in practice, a C-shape is sufficient. The baffle 1 is hollow inside, and the lower end of the baffle 1 is open. An elastic latex membrane 2 with an arc-shaped cross-section is provided at the opening to conform to the skin. The latex membrane 2 can conform to the skin and is not easy to leak. It also includes a dual-suction mechanism on the latex membrane 2 that can simultaneously absorb the skin and the liquid inside, and a liquid suction mechanism installed inside the latex membrane 2 to remove waste liquid. The dual-suction mechanism mainly adsorbs the skin to fix the latex membrane 2 and prevent it from lifting and leaking water. At the same time, it can also absorb waste liquid and remove it. The liquid suction mechanism further removes and discharges the waste liquid brought by the dual-suction mechanism. The toughness of the latex film can be adjusted according to its thickness. It should not be too soft because the inside is under negative pressure. The latex film needs to maintain a certain state, just enough to deform and fit the skin when suctioning. Moreover, the amount of deformation does not need to be too large, because the skin itself is soft and the fit is good.

[0028] The dual-absorption mechanism includes multiple adsorption holes 3 formed at the bottom of the latex membrane 2 to adhere to the skin. These holes 3 extend inwards and upwards to form elongated shapes for convenient adsorption of waste liquid. For ease of description, the baffle 1 can open to the right, and the adsorption holes 3 are elongated. The bottom of these holes adheres to the skin, securing the latex membrane 2 to the skin. The rightward and upward extensions can absorb horizontally flowing waste liquid. This dual-purpose design allows for both skin adhesion and waste liquid absorption. Compared to two separate holes, when no liquid is flowing, only the skin is adsorbed, with some air entering. This prevents excessive suction on the skin, reducing pressure and discomfort. When waste liquid is flowing, it can be absorbed; when no waste liquid is flowing, the adsorption holes 3... The surrounding latex membrane 2 deforms and presses down due to negative pressure, increasing the skin contact area and achieving better adsorption. It is equivalent to the adsorption hole 3 converting the part that adsorbs waste liquid into the part that adsorbs skin. When there is a lot of waste liquid, some liquid will rush into the bottom contact part of the adsorption hole 3, which is equivalent to converting part of the space into the liquid absorption part, increasing the liquid absorption effect. Moreover, the adsorption of waste liquid is cleaner and more thorough because the adsorption hole 3 is in contact with the skin. Therefore, compared to the combination of adsorbing skin and absorbing waste liquid with one hole, this one hole has two uses. It not only achieves the function of two holes, but is also superior to both, and is safer and more comfortable.

[0029] The liquid suction mechanism includes a suction tube 4 located within the latex membrane 2 along its length and a suction hole 5 formed on the suction tube 4. A negative pressure tube 6 extending out of the latex membrane 2 is connected to the middle of the suction tube 4. The suction hole 5 can be located at the bottom. Of course, the suction tube 4 has a circular cross-section, so the suction hole 5 will not be blocked and will extend to both sides.

[0030] It also includes a waste liquid backflow prevention mechanism installed inside the latex membrane 2. This prevents waste liquid from flowing back through the adsorption holes 3 when the negative pressure stops. The backflow prevention mechanism includes an anti-backflow tube 7 connected to the inner end of the adsorption holes 3 and pointing upwards, with a through hole 8 on the upper side of the anti-backflow tube 7. The through hole 8 is located on the upper side, and the liquid is located at the bottom of the latex membrane 2, so it will not spill out. The anti-backflow tube 7 is made of the same material as the latex membrane 2, and the through hole 8 is formed by a slit so that it can be closed together by elastic force to prevent backflow under normal conditions. The through hole 8 is formed by making a slit or opening in the anti-backflow tube 7, so that it is closed together under normal conditions and will not leak. To improve stability, the bottom of the anti-backflow tube 7 can be wider. The upper end of the anti-backflow tube 7 is inclined towards the center of the baffle 1 in an arc-shaped bend, and the end of the bend abuts against the inner wall of this side to achieve elastic compression of the through hole 8, and the through hole 8 is opened on the back of the bend. By utilizing the elastic force of the bent part against the inner wall of the baffle 1, the through hole 8 is closed more tightly, so that it is not easy to be opened during movement, thus preventing waste liquid from spilling out.

[0031] The baffle 1 is made of latex material that can be bent and deformed under stress to fit the skin. The wall thickness can be increased to maintain its shape; for example, its rigidity can be similar to a belt in a car engine, possessing both rigidity and deformability. Its toughness can be determined based on the wall thickness and the specific material. The upper wall of the inner cavity of the baffle 1 is equipped with support strips 9 that can be bent and deformed under stress to support the shape of the baffle 1. Materials such as aluminum alloy, aluminum, and gooseneck tubing that can maintain their shape after bending can be used.

[0032] Working Principle: The latex membrane 2 is flexible and can adhere to the skin. The adsorption holes 3 can adhere to the skin for fixation, eliminating the need to press down on the baffle 1; simply holding it is sufficient. It also adsorbs waste liquid, ensuring skin adhesion and promptly removing waste liquid to prevent accumulation and spillage. When the waste liquid is small, the adsorption holes 3 deform downwards under the negative pressure inside the latex membrane 2, increasing the contact area with the skin and thus the adsorption area, improving the adsorption effect. This ensures the tension of the latex membrane 2 between the two adsorption holes 3, enhancing the adhesion to the skin. When the waste liquid increases, some will flow to the lower side of the adsorption holes 3, thus increasing the area for adsorbing waste liquid and improving the waste liquid absorption effect. The baffle 1 is flexible and can conform to the skin, working in conjunction with the latex membrane 2 to accommodate the curves of the body. The inner support strip 9 ensures the stability of the deformed shape, better adhering to the skin and preventing leakage. Furthermore, the flexibility of the latex membrane 2 provides comfort, utilizing self-adsorption to adhere to the skin without the need to press down on the baffle 1, saving effort. The adsorption pore 3 can adhere to the skin to achieve fixation and prevent leakage, and can also adsorb waste liquid. There is no gap between the waste liquid and the skin, so the adsorption is more thorough.
