Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a hydrocolloid catheter fixation patch. Background Technology

[0002] When people are injured, they use wound dressings for wound care. It is well known that wound healing involves a large amount of exudate. Maintaining a suitable moist environment while avoiding excessive exudate is crucial for wound healing. Too much or too little exudate, or the presence of harmful components in the exudate, can lead to various problems and ultimately delay wound healing. Clinical research and practice have shown that applying negative pressure near the wound site can accelerate the growth of new tissue, absorb exudate from the wound, promote beneficial biological responses at the wound site, and reduce the possibility of contaminants and microorganisms entering the wound.

[0003] Currently, in order to create a relatively sealed negative pressure environment near the wound, a plastic shell is usually used to surround the wound. A catheter connected to the negative pressure source passes through the plastic shell and extends into the vicinity of the wound. However, the plastic shell is relatively hard, which is not very comfortable for the human body, and may also compress the wound and affect wound healing. Utility Model Content

[0030] Please see Figure 1 and Figure 2 One embodiment of this utility model provides a hydrocolloid catheter fixation patch, comprising: a hydrocolloid dressing 10.

[0031] The hydrocolloid dressing 10 includes a surrounding portion 11 and a fixing portion 12. The surrounding portion 11 is arranged around the fixing portion 12. The thickness of the fixing portion 12 is greater than that of the surrounding portion 11. The top of the fixing portion 12 is provided with a fixing groove 121 for fixing the conduit 40. One side of the fixing groove 121 is provided with an opening 122 for the conduit 40 to pass through. The bottom of the fixing groove 121 is provided with a through hole 123 for the conduit 40 to pass through.

[0032] The hydrocolloid dressing 10 has the ability to absorb wound exudate. After absorbing the exudate, the hydrophilic particles in the hydrocolloid dressing 10 can form a gel-like semi-solid substance that adheres to the base of the wound, providing and maintaining a moist environment conducive to wound healing. It also has self-adhesive properties, allowing it to adhere to the skin near the wound to form a closed healing environment. This promotes the proliferation of microvessels and the formation of granulation tissue, thereby accelerating wound healing and preventing contaminants and microorganisms from entering the wound.

[0033] Before use, insert the catheter 40 into the fixing groove 121 through the opening 122, and then through the through hole 123. Because the hydrocolloid dressing 10 has its own adhesiveness and elasticity, the catheter 40 can be adhered to and squeezed in the fixing groove 121. When using, place the bottom of the perimeter 11 and the fixing part 12 close to the surface of the human skin. The bottom of the fixing part 12 is at the wound, while the perimeter 11 is adhered to the skin near the wound. A closed healing environment is formed between the perimeter 11, the fixing part 12 and the surface of the human skin. The catheter 40 enters the healing environment through the through hole 123. The catheter 40 is connected to a negative pressure source, which can provide negative pressure to the healing environment and allow the exudate from the wound to be drawn out of the healing environment through the catheter 40, which is beneficial to wound healing.

[0034] In some alternative embodiments, the edging portion 11 and the fixing portion 12 are integrally formed, which facilitates production and simplifies the structure.

[0035] In some optional embodiments, the fixing groove 121 includes a bending groove 124, which communicates with the opening 122 and the through hole 123. The bending groove 124 allows the conduit 40 to bend. Since the conduit 40 has a certain elasticity, the bending groove 124 causes the conduit 40 to bend and be pressed against the inner wall of the fixing groove 121 by its own elasticity. The hydrocolloid dressing 10 has elasticity and stickiness, so the fixing groove 121 is concave due to the pressure of the conduit 40, which can position the positioning recess of the conduit 40 and prevent the conduit 40 from falling out of the fixing groove 121. Moreover, the positioning recess and the conduit 40 will also adhere to each other, further preventing the conduit 40 from falling out of the positioning recess, making it difficult for the conduit 40 to fall out of the fixing groove 121, thus achieving stable fixation of the conduit 40.

[0036] Please see Figure 3In some optional embodiments, the fixing groove 121 further includes an inlet groove 125. An opening 122 is provided on one side of the inlet groove 125. A first connecting port 1251 and a second connecting port 1252 are provided on the side of the inlet groove 125 away from the opening 122. The two ends of the bending groove 124 are respectively connected to the first connecting port 1251 and the second connecting port 1252. A through hole 123 is located at the second connecting port 1252. The conduit 40 enters the inlet groove 125 from the opening 122, then enters the bending groove 124 from the first connecting port 1251, then extends along the bending groove 124 to the second connecting port 1252, and then enters the through hole 123. Since the conduit 40 bends around the bending groove 124, the conduit 40 can generate a large elastic deformation, which is beneficial to improve the elasticity of the conduit 40 and make the conduit 40 stably fixed in the fixing groove. The elastic force of the portion of the conduit 40 located within the bending groove 124 will cause the portion of the conduit 40 located outside the bending groove 124 to shift its position. Therefore, the elastic force of the portion of the conduit 40 located within the bending groove 124 will cause the portion of the conduit 40 located within the guide groove 125 to press against the inner wall of the guide groove 125. The guide groove 125 can fix and position the conduit 40, which is beneficial to ensure that the position layout of the conduit 40 located outside the fixing groove 121 is not affected by the elastic force of the portion of the conduit 40 located within the bending groove 124.

[0037] In some optional embodiments, the curved groove 124 includes a first straight section 1241, a curved section 1242, and a second straight section 1243 connected in sequence. The end of the first straight section 1241 away from the curved section 1242 is connected to a first connecting port 1251, and the end of the second straight section 1243 away from the curved section 1242 is connected to a second connecting port 1252. The first straight section 1241 and the second straight section 1243 gradually move away from each other in the direction away from the inlet groove 125. When the conduit 40 enters the first straight section 1241 from the inlet groove 125, the conduit 40 gradually generates... The conduit 40 bends significantly around the curved section 1242. The first straight section 1241 provides a certain transition for the conduit 40, preventing the conduit from bending and becoming blocked. Subsequently, the conduit 40 enters the second straight section 1243 and is straightened by the second straight section 1243 before passing through the through hole 123. The second straight section 1243 can prevent the conduit 40 from bending excessively. Moreover, after the conduit 40 is straightened, the part of the conduit 40 that passes through the through hole 123 and enters the healing environment is more easily positioned in a suitable location and is less susceptible to large deviations due to elasticity.

[0038] In some optional embodiments, an arc-shaped concave portion can be provided on the inner wall of the inlet groove 125 and the inner wall of the bending groove 124. The arc-shaped concave portion matches the shape of the conduit 40, so that the arc-shaped concave portion can stably fit the conduit 40, increasing the contact area with the conduit 40, which is conducive to a more stable adhesion between the arc-shaped concave portion and the conduit 40. Moreover, the width of the top opening of the inlet groove 125 and the top opening of the bending groove 124 can be smaller than the diameter of the conduit 40, thereby further preventing the conduit 40 from detaching from the top opening of the inlet groove 125 and the top opening of the bending groove 124.

[0039] In some alternative embodiments, a first slit 111 is provided on the perimeter 11. The first slit 111 extends from the outer edge of the perimeter 11 to the opening 122, and then extends to the through hole 123 in the fixing groove 121. The first slit 111 penetrates the top and bottom of the perimeter 11 and the top and bottom of the fixing part 12. To facilitate the passage of the conduit 40 through the through hole 123, the first slit 111 can separate a portion of the perimeter 11 and the fixing part 12. The conduit 40 can directly enter the through hole 123 along the first slit 111, thus allowing the conduit 40 to pass through the through hole 123. Then, the conduit 40 is inserted into the fixing groove 121 along its direction, thereby enabling the conduit 40 to be quickly installed.

[0040] Please see Figure 4 In some optional embodiments, a third slit 112 is provided at the end of the first slit 111. The third slit 112 penetrates the top and bottom of the fixing part 12. The first slit 111 is connected to the through hole 123 through the third slit 112. The angle between the extension direction of the first slit 111 and the extension direction of the third slit 112 is an obtuse angle. The purpose of this design is to form a certain turning position, so that the conduit 40 needs to undergo a certain bending displacement to enter the first slit 111, thereby increasing the difficulty for the conduit 40 to enter the first slit 111 from the through hole 123 and preventing the conduit 40 from directly entering the first slit 111 from the through hole 123 and detaching.

[0041] Please see Figure 4 and Figure 5 In some optional embodiments, the hydrocolloid conduit fixing adhesive also includes release paper 20, with the edge portion 11 and the fixing portion 12 detachably attached to the top of the release paper 20. The release paper 20 can prevent the bottom of the edge portion 11 and the fixing portion 12 from being contaminated before use, effectively protecting the edge portion 11 and the fixing portion 12.

[0042] In some alternative embodiments, the hydrocolloid conduit fixing adhesive also includes release paper 20, with the edge portion 11 and the fixing portion 12 detachably attached to the top of the release paper 20. The release paper 20 is provided with a second slit portion 21, which divides the release paper 20 into a first release portion 22 and a second release portion 23. The position of the second slit portion 21 corresponds to the position of the first slit portion 111. The conduit 40 can simultaneously enter the first slit portion 111 and the second slit portion 21, and then move along the first slit portion 111 and the second slit portion 21 to the through hole 123, so that the conduit 40 passes through the through hole 123. At this time, the release paper 20 is still attached to the edge portion 11 and the fixing portion 12, which can prevent the bottom of the edge portion 11 and the fixing portion 12 from being contaminated when the conduit 40 is installed. Since the release paper 20 can be peeled off when the bottom of the edge portion 11 and the fixing portion 12 needs to be attached to the human skin, it avoids the bottom of the edge portion 11 and the fixing portion 12 being contaminated by peeling off the release paper 20 in advance.

[0043] Please see Figure 6 In some optional embodiments, the hydrocolloid catheter fixation patch further includes a non-woven adhesive tape 30. The non-woven adhesive tape 30 covers the top of the perimeter portion 11 and the fixing portion 12, used to constrain the catheter 40 onto the fixing portion 12 and the perimeter portion 11. The non-woven adhesive tape 30 covering the fixing portion 12 can close the top opening of the fixing groove 121, thereby further preventing the catheter 40 from detaching from the fixing groove 121. The non-woven adhesive tape 30 covering the perimeter portion 11 can adhere the catheter 40 to the perimeter portion 11, further fixing the catheter 40 and improving the positional stability of the catheter 40. The size of the non-woven adhesive tape 30 can be designed according to actual needs. The non-woven adhesive tape 30 can also extend beyond the perimeter portion 11 to adhere to the skin, further fixing the hydrocolloid dressing 10 to the skin surface, improving the sealing of the healing environment and the adhesion stability of the hydrocolloid dressing 10.

[0044] In some alternative embodiments, the depth of the fixing groove 121 is 3mm-5mm. In this embodiment, the depth of the fixing groove 121 is 4mm, and a sufficiently deep fixing groove 121 can stably install the conduit 40.

[0045] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
