Description

Technical Field

[0001] The present invention belongs to the field of wound care, and particularly relates to a traditional Chinese medicine paste applicator for diabetic foot. Background Art

[0002] Diabetic foot is the most common complication of diabetic patients. Due to the abnormal nerves in the distal lower extremities and varying degrees of vascular lesions in diabetic patients, foot ulcers and infections are caused, deep tissue damage occurs, exogenous bacteria invade, resulting in low efficiency of white blood cell response. Inflammation and tissue damage are the result of repeated stress to a certain extent acting on a specific insensitive area. In addition, hyperglycemia and malnutrition can jointly cause tissue edema, tissue swelling, etc.

[0003] Due to the infection, ulcer, and tissue swelling of the wound of diabetic foot, the affected skin may present a convex ulcerated and damaged wound surface. And because it is an infectious wound, in order to prevent the bacteria at the damaged area from spreading to the surrounding of the wound, generally, disinfection or application of ointment is carried out from the outside to the inside. The method of applying ointment from the outside to the inside can play a buffering role in the wound surface at the damaged area when applying the ointment, which helps to reduce the irritation of the wound at the damaged area. And in the wound care of diabetic foot, keeping the wound surface moist within a certain period of time can promote the wet healing of diabetic foot. Traditional Chinese medicine pastes such as Sanhuang Paste are generally semi-solid pastes with strong viscosity and are not easy to spread. They are often used for external application on diabetic foot. And clinically, applying ointment with cotton swabs may cause cotton fluffs to remain on the wound, and the mechanical friction and other stimulations during application may lead to exacerbation of the wound surface.

[0004] Therefore, due to the difficulty in applying traditional Chinese medicine pastes such as Sanhuang Paste, it is ensured that bacteria at the ulcerated area spread to the surrounding of the wound during the process of applying traditional Chinese medicine paste for diabetic foot, resulting in cross-infection, exacerbating the wound surface irritation, and it is difficult to ensure the aseptic and the treatment effect of wet healing of diabetic foot. Therefore, a new technology is needed to improve this phenomenon. Summary of the Invention

[0005] In view of the above problems in the prior art, the present invention provides a traditional Chinese medicine paste applicator for diabetic foot, which makes the application of traditional Chinese medicine pastes such as Sanhuang Paste more convenient, and the application method is from the outside to the inside of the wound of the wound surface, avoiding cross-infection, causing less irritation to the wound of the wound surface, and being able to ensure the aseptic and the treatment effect of wet healing of diabetic foot.

[0006] The present invention is implemented through the following technical solutions: A traditional Chinese medicine paste applicator for diabetic foot, including an annular pad, the annular pad is arranged horizontally, the outer edge of the annular pad forms a sealed connection with the edge of the closed cover, and the inner edge of the annular pad forms a sealed connection with the edge of the pressing cover;

[0007] The compression cover is located inside the closed cover. The outer surface of the compression cover, the inner wall of the closed cover, and the upper surface of the annular pad enclose a sealed extrusion cavity. In the middle section of the side wall of the cover body of the closed cover, there is a section of extrusion bladder that bulges outward. The inner cavity of the extrusion bladder communicates with the sealed extrusion cavity.

[0008] The wall thickness x of the extrusion bladder and the wall thickness y of the closed cover satisfy y > x. The annular pad is used to adhere to the human epidermis. The inner cavity of the compression cover is used to accommodate the wound surface. The compression cover includes a compression part, a transition part, and a closing part that are sequentially connected from bottom to top. The compression part and the transition part are both annular bodies, and the closing part is a cover body. The compression part is made of elastic material. The lower end of the compression part fits with the annular pad.

[0009] The wall thickness of the axial section of the compression part shows an increasing trend from bottom to top. The wall thickness of the axial section of the transition part forms a narrowing trend from both ends to the middle. The average wall thickness a of the compression part, the average wall thickness b of the transition part, and the average wall thickness c of the closing part satisfy b < a < c.

[0010] The arc length m of the vertical section of the compression part and the arc length n of the vertical section of the transition part satisfy m > n.

[0011] Further, the closed cover and the compression cover are made of medical silicone rubber material, and the annular pad is made of synthetic silicone material.

[0012] Further, the closed cover and the compression cover are connected to the annular pad in a heat-sealed form.

[0013] Further, the sealed extrusion cavity is filled with gas.

[0014] Further, a medical glue layer is provided at the lower end of the annular pad, and the annular pad is attached to the human epidermis through the medical glue layer.

[0015] Further, a traditional Chinese medicine paste layer is applied to the inner wall of the compression part.

[0016] Further, when the extrusion bladder is squeezed, the compression part is in a centripetal elastic deformation posture and adheres to the outside of the wound surface of the wound. The vertical height o at the lower end of the transition part and the average height e in the middle of the wound surface of the wound satisfy o > e.

[0017] Beneficial effects

[0018] In the present invention, through the setting that the wall thickness of the axial section of the compression part gradually increases from bottom to top and the wall thickness of the axial section of the transition part forms a gradually narrowing trend from both ends to the middle, morphological compensation is carried out for the torsional deformation of the compression part, and at the same time, the torsional stress of the compression part is released, so that the upper end closing part is not affected by torsion. In this way, the compression deformation of the compression part forms a separate concave state, and the compression sequence is from bottom to top, which is adapted to the extrusion of the swollen wound surface protruding from the normal skin caused by infected ulcers, etc. Therefore, when the inner wall of the compression part is coated with traditional Chinese medicine paste, due to the bottom-up compression sequence of the compression part, the traditional Chinese medicine paste is extruded from the outside of the wound surface of the wound towards the middle of the wound surface of the wound, forming a uniform layer of traditional Chinese medicine paste on the outside of the wound surface of the wound, and pushing the excess traditional Chinese medicine paste towards the middle of the wound surface of the wound, forming a layer of traditional Chinese medicine paste completely covering the wound surface of the wound. Since the traditional Chinese medicine paste covering the middle of the wound surface of the wound is formed by squeezing and piling up the excess ointment by the compression part, it can reduce the irritation of the wound surface, realize the application of the traditional Chinese medicine paste from the outside to the inside of the wound surface of the wound, the application is convenient and the wound surface of the wound can be maintained in the compression cover, ensuring the moisture of the wound surface of the wound, promoting the wet healing of the wound. At the same time, it can avoid the ointment being rubbed off and causing wound contamination, ensuring sterility during the medicine application process and avoiding cross-infection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The present invention will be further described in detail below with reference to the accompanying drawings of the specification and the embodiments.

[0028] A traditional Chinese medicine paste applicator for diabetic foot, as Figures 1-6 shown, includes an annular pad 5. The annular pad 5 is arranged horizontally. The outer edge of the annular pad 5 forms a sealed connection with the edge of the closed cover 2. The inner edge of the annular pad 5 forms a sealed connection with the edge of the compression cover 4. The compression cover 4 is located inside the closed cover 2. An airtight extrusion cavity 3a is formed by the outer surface of the compression cover 4, the inner wall of the closed cover 2, and the upper surface of the annular pad 5. The closed setting facilitates the formation of the airtight extrusion cavity 3a between the compression cover 4, the closed cover 2, and the annular pad 5.

[0029] In the middle section of the side wall of the cover body of the closed cover 2, a section of extrusion bladder 3b protruding outward is connected. The inner cavity of the extrusion bladder 3b communicates with the airtight extrusion cavity 3a. The above setting can enable the airtight extrusion cavity 3a to generate a uniform pressing force on the compression cover 4 when the extrusion bladder 3b is extruded; the wall thickness x of the extrusion bladder 3b and the wall thickness y of the closed cover 2 satisfy y > x. The above setting facilitates the formation of the extrusion bladder 3b.

[0030] The annular pad 5 is used to attach to the human epidermis. More specifically, it attaches to the normal skin 1 outside the wound surface of the diabetic foot. The inner cavity of the compression cover 4 is used to accommodate the wound 1a. The above setting can enable the whole device to be fixed on the human epidermis, maintain a sterile environment during the process of applying the traditional Chinese medicine paste, and keep the compression cover 4 covering the wound 1a outside after the paste is applied. By maintaining the closed form of the wound 1a, the moist state of the wound after applying the medicine can be ensured, promoting the wet healing of the wound. At the same time, it can prevent the paste from being rubbed off and causing wound contamination.

[0031] The compression cover 4 includes a compression part 4a, a transition part 4b, and a closing part 4c that are connected in sequence from bottom to top. The compression part 4a and the transition part 4b are both annular bodies. The closing part 4c is a cover body. The compression part 4a is made of an elastic material, and the elastic material enables the compression part 4a to be elastically deformed.

[0032] The lower end of the pressing part 4a is attached to the annular pad 5, and the wall thickness of the axial section of the pressing part 4a shows an increasing trend from bottom to top. The above settings can enable the pressing part 4a to form a centripetal pressure on the outer side of the diabetic foot wound 1a first when elastic deformation occurs, and the order of pressure is from bottom to top. In the state where the traditional Chinese medicine paste is applied to the inner wall of the pressing part 4a, the traditional Chinese medicine paste is squeezed from the outside to the inside of the wound 1a due to the bottom-up pressing order of the pressing part 4a, forming a uniform traditional Chinese medicine layer, and pushing the excess traditional Chinese medicine paste towards the middle of the wound 1a, forming a traditional Chinese medicine paste layer 6 that completely covers the wound 1a. And because the traditional Chinese medicine paste covering the middle of the wound 1a is formed by squeezing the excess paste by the pressing part 4a, it avoids the secondary mechanical damage caused by the contact or friction between the most severe wound 1a in the middle and the pressing cover 4, which aggravates the severity of the wound 1a, and realizes the application from the outside to the inside of the wound 1a, avoiding cross-infection.

[0033] The wall thickness of the axial section of the transition part 4b forms a narrowing trend from both ends to the middle, which can be equivalent to the shape of the shaft body function, so as to compensate for the distortion deformation of the pressing part 4a, and at the same time release the distortion stress of the pressing part 4a, so that the upper closing part 4c is not affected by the distortion, so that the compressive deformation of the pressing part 4a forms a single concave state (as Figure 7 shown).

[0034] The average wall thickness a of the pressing part 4a, the average wall thickness b of the transition part 4b, and the average wall thickness c of the closing part 4c satisfy b < a < c. The above settings can realize the elastic deformation of the pressing part 4a when the extrusion bladder 3b is extruded

[0035] The vertical section arc length m of the pressing part 4a and the vertical section arc length n of the transition part 4b satisfy m > n, further realizing that the transition part 4b is equivalent to the shaft body function, compensating for the distortion deformation of the pressing part 4a, and at the same time releasing the distortion stress of the pressing part 4a, so that the upper closing part 4c is not affected by the distortion, so that the compressive deformation of the pressing part 4a forms a single concave state.

[0036] In this embodiment, when squeezing the extrusion bladder 3b, the sealed extrusion cavity 3a generates a uniform pressing force on the compression cover 4. The wall thickness of the axial section of the compression part 4a gradually increases from bottom to top, and the wall thickness of the axial section of the transition part 4b forms a narrowing trend from both ends to the middle. This setting compensates for the morphological distortion of the compression part 4a and releases the torsional stress of the compression part 4a at the same time, so that the upper end closing part 4c is not affected by torsion. In this way, the compression deformation of the compression part 4a forms a separate concave state, and the order of compression is from bottom to top, which is suitable for squeezing the swollen wound 1a protruding from the normal skin 1 caused by infected ulcers, etc. Therefore, when the inner wall of the compression part 4a is coated with traditional Chinese medicine paste, due to the bottom-up compression order of the compression part 4a, the traditional Chinese medicine paste is squeezed from the outside of the wound 1a to the middle of the wound 1a, forming a uniform traditional Chinese medicine paste layer 6 on the outside of the wound 1a, and pushing the excess traditional Chinese medicine paste towards the middle of the wound 1a, forming a traditional Chinese medicine paste layer 6 that completely covers the wound 1a. Since the traditional Chinese medicine paste covering the middle of the wound 1a is formed by squeezing and piling up the excess paste by the compression part 4a, it avoids the secondary mechanical damage caused by the contact and friction of the middle part of the wound 1a with serious infection or damage when contacting the compression cover 4, which aggravates the severity of the wound 1a. It realizes the application of the traditional Chinese medicine paste from the outside to the inside of the wound 1a, which is convenient for application, and can keep the wound 1a covered in the compression cover 4, ensure the moisture of the wound 1a, avoid promoting the wet healing of the wound, and at the same time, it can avoid the paste being rubbed off and causing wound contamination, ensure sterility during the medicine application process, and avoid cross-infection.

[0037] In this embodiment, the sealing cover 2 and the compression cover 4 are made of medical silicone rubber material, and the annular pad 5 is made of synthetic silicone material, which is convenient for the formation of the extrusion bladder 3b and the formation of an inner concave state of the compression layer.

[0038] In this embodiment, the sealing cover 2 and the compression cover 4 are connected to the annular pad 5 in a heat-sealed form, which is convenient for the formation of the sealed extrusion cavity 3a.

[0039] In this embodiment, a medical adhesive layer 5a is provided at the lower end of the annular pad 5, and the annular pad 5 is attached to the human epidermis through the medical adhesive layer 5a. A traditional Chinese medicine paste layer 6 is applied to the inner wall of the compression part 4a, which is convenient for the application of the traditional Chinese medicine paste from the outside to the inside of the wound 1a.

[0040] In this embodiment, when squeezing the extrusion bladder 3b, the compression part 4a is in a centripetal elastic deformation posture and adheres to the outside of the wound 1a. The vertical height o at the lower end of the transition part 4b and the average height e at the middle of the wound 1a of the wound 1a satisfy o > e. The above settings are convenient for the compression part 4a to adhere to the outside of the wound 1a to a greater extent, so as to ensure the integrity of the traditional Chinese medicine paste layer 6 covering the wound 1a.

[0041] The working principle of this embodiment is as follows:

[0042] S1: Debride and clean the wound 1a of diabetic foot. There is a plaster layer on the lower end of the inner wall of the compression part 4a of this device. Attach the annular pad 5 of this device to the normal skin 1 outside the wound 1a of diabetic foot through the medical glue layer 5a, so that the whole compression cover 4 covers the wound 1a of diabetic foot.

[0043] S2: Squeeze the extrusion bladder 3b. Since the closed extrusion cavity 3a and the extrusion bladder 3b are connected through, and filled with gas, the wall thickness of the axial section of the transition part 4b is set to gradually narrow from both ends to the middle, compensating for the morphological distortion of the compression part 4a, and at the same time releasing the torsional stress of the compression part 4a, so that the upper end closed part is not affected by torsion. In this way, the compressive deformation of the compression part 4a forms a single concave state. The wall thickness of the axial section of the compression part 4a gradually thickens from bottom to top, and the average wall thickness a of the compression part 4a, the average wall thickness b of the transition part 4b, and the average wall thickness c of the closing part 4c satisfy b < a < c. When the closed extrusion cavity 3a generates a uniform extrusion force on the compression cover 4, an inward concave compression form from bottom to top on the outside of the wound 1a of diabetic foot is formed in the compression part 4a, so that the traditional Chinese medicine plaster layer 6 smeared on the inner wall of the compression part 4a is extruded to the outside of the wound 1a of diabetic foot, and along with the upward deformation and extrusion trend of the compression part 4a, it is extruded from the outside of the wound 1a of diabetic foot to the center direction to form a uniform traditional Chinese medicine plaster layer 6 on the outside of the wound 1a of diabetic foot, and the excess traditional Chinese medicine plaster is piled up in the middle of the wound 1a of diabetic foot to form a complete traditional Chinese medicine plaster layer 6. The sealing during the operation process ensures aseptic operation, avoids infection or the secondary mechanical injury caused by the most serious wound 1a in the middle contacting the compression cover 4 to generate friction, contact, etc., which aggravates the severity of the wound 1a, realizes the application of the traditional Chinese medicine plaster from the outside to the inside of the wound 1a, and avoids cross-infection.

[0044] S3: Relax the extrusion bladder 3b to make the compression part 4a return to its original state. The medical glue layer 5a attaches to the normal skin 1 outside the wound 1a of diabetic foot to keep this device in a fixed state, and the compression cover 4 remains covering the wound 1a of diabetic foot, keeping the wound 1a moist, avoiding promoting the wet healing of the wound. At the same time, it can prevent the plaster from being rubbed off and causing wound contamination.

[0045] The present invention has been specifically described above in connection with the embodiments. Without departing from the core scope of the present invention, various improvements can still be made, and components therein can be replaced with equivalents. As long as there is no structural conflict, the features in the embodiments disclosed in the present invention can be combined with each other in any way. The present specification does not exhaustively describe these combination cases, which is only for the consideration of saving space and resources. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed in the text, but covers all technical solutions falling within the scope of the claims.
