Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical dressings, in particular to a medical dressing for compressing a puncture wound surface. BACKGROUND

[0002] In clinical medical treatment, after invasive operations such as closed thoracic drainage, abdominal cavity drainage, and central venous catheter placement, the removal of the drainage tube is a routine step. After the tube is removed, the puncture channel (tunnel) left in the subcutaneous tissue and muscle layer often cannot be closed immediately, resulting in continuous exudation of blood, tissue fluid, bile, or pleural effusion from the deep part. This leakage not only soaks the dressing and the surrounding skin, increasing the patient's discomfort, but also is an important risk factor for local infection, skin maceration, and even delayed healing of the wound.

[0003] In the prior art, the medical wound dressing provided by the publication number CN216318386U has a drainage through hole to ensure that the wound effusion and pus can be smoothly drained, prevent wound infection, and accelerate wound healing. The size of the drainage through hole is set to prevent the hole from being too large to expose the wound and too small to drain the effusion. The dressing is set in multiple different shapes to cover the wound surface of different body parts without the need for further cutting, reducing the waste of the dressing and the workload of medical staff.

[0004] The prior art in the above patent has the following defects when in use: first, the flat dressing can only apply pressure to the skin surface, the pressure is dispersed, and it cannot effectively act on the subcutaneous puncture tunnel, so the exudate is easily exuded from the edge of the dressing, and the compression effect is limited; second, when a small amount of exudate breaks through the compression point, if the absorption layer of the traditional dressing cannot absorb and lock the body fluid in time, the exudate is likely to flow back, polluting the wound and macerating the surrounding healthy skin, affecting the recovery of the wound.

[0005] The present application proposes a medical dressing for compressing a puncture wound surface to comprehensively improve the efficiency, energy saving, and intelligence of pharmaceutical freeze-drying production. SUMMARY

[0016] Beneficial effects Compared with the prior art, the utility model provides a medical dressing for pressing puncture wound surface, which has the following beneficial effects: 1、The invention adopts a hemispherical compression assembly that can extend into the wound surface. This structure breaks through the limitations of traditional flat dressings and can directly and accurately transmit pressure to the puncture path of the subcutaneous tissue layer and muscle layer, effectively closing the main channel of body fluid exudation from a physical perspective, achieving "targeted compression".

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Please refer to Figures 1-7 The medical dressing for compressing a puncture wound surface provided in the embodiments of the present application comprises a base layer 1, a dressing layer 2 and a compression assembly 3. The base layer 1 is in a rectangular structure and is made of an elastic and breathable material. The front end surface of the base layer 1 is an adhesive structure. The compression assembly 3 is adhered to the middle part of the front end surface of the base layer 1. The dressing layer 2 is also adhered to the front end surface of the base layer 1. The dressing layer 2 is in a rectangular structure. A through hole for compressing the edges of the compression assembly 3 is formed in the middle part of the dressing layer 2. The compression assembly 3 is in a hemispherical structure. The front end of the compression assembly 3 protrudes from the surface of the dressing layer 2. The compression assembly 3 is used to compress the puncture wound surface.

[0030] In the above technical solution, after the drainage tube is removed, the exudation of body fluid mainly comes from the puncture path of the subcutaneous tissue layer and the muscle layer. When the puncture wound surface of the patient is compressed, the hemispherical compression assembly 3 is inserted into the wound surface to compress the wound surface, significantly reducing or preventing the exudation of body fluid from the deep part to the surface, keeping the dressing and the surrounding skin dry, and being beneficial to the recovery of the wound surface. At the same time, the number of dressing changes can be reduced, the nursing time can be saved, and the treatment cost of complications such as leakage and infection can be reduced.

[0031] Please refer to Figures 1-2 As the preferred technical solution of the present embodiment, the dressing layer 2 comprises, from the outside to the outside, a breathable layer, a pharmacological layer and a diaphragm layer.

[0032] In the above technical scheme, the air-permeable layer serves as the first barrier to effectively prevent liquid (such as domestic water, dirt), bacteria and microorganisms from the outside from entering and protecting the wound from being contaminated, and the pharmacological layer is composed of high-absorbent materials which can load specific drug components; when a small amount of exudate penetrates through the diaphragm layer to contact the layer, the drug is slowly and continuously released to act on the wound surface; the diaphragm layer material will not stick to the newly formed granulation tissue or blood scab, and can be easily removed without pain during the replacement of the dressing, thus causing no secondary damage and bleeding.

[0033] Referring to Figures 3-4 As shown in the preferred technical scheme of the embodiment, the compression assembly 3 comprises a ring-shaped spacer 31, an inner silica gel hemisphere 32, an outer silica gel hemisphere 33 and a connecting channel 34, the ring-shaped spacer 31 is adhered to the middle of the front end of the base layer 1, the inner silica gel hemisphere 32 and the outer silica gel hemisphere 33 are installed at the front end of the ring-shaped spacer 31, the diameter of the outer silica gel hemisphere 33 is greater than that of the inner silica gel hemisphere 32, the area between the inner silica gel hemisphere 32 and the outer silica gel hemisphere 33 is set as a sealed cavity, and the connecting channel 34 is uniformly installed between the inner silica gel hemisphere 32 and the outer silica gel hemisphere 33, the connecting channel 34 is a flexible hollow structure, and the outer side of the outer silica gel hemisphere 33 is connected with the inside of the inner silica gel hemisphere 32 through the connecting channel 34.

[0034] In the above technical scheme, when the puncture wound surface of the patient is compressed, the outer silica gel hemisphere 33 extends into the wound surface, the sealed cavity between the inner silica gel hemisphere 32 and the outer silica gel hemisphere 33 is an inflatable cavity, the pressure of the outer silica gel hemisphere 33 on the wound surface is changed by inflating the inside of the sealed cavity, thereby being able to adapt to different sizes of wound surfaces, ensuring that the wound surface can be fully compressed, and significantly reducing or preventing body fluid from seeping from the deep to the surface; meanwhile, the inner silica gel hemisphere 32 is arranged with an adsorbent material, which can adsorb the body fluid on the outside of the outer silica gel hemisphere 33 through the connecting channel 34, thereby being able to both compress the wound surface to reduce the overflow of body fluid and adsorb and collect the body fluid that has already seeped out.

[0035] It should be noted that the adsorbent material arranged in the middle of the inner silica gel hemisphere 32 is preferably a superabsorbent polymer, which can immediately combine with water molecules and quickly swell when the body fluid enters the inside of the inner silica gel hemisphere 32 through the connecting channel 34, thereby "locking" the liquid in the gel state and preventing the body fluid from flowing back into the inside of the inner silica gel hemisphere 32.

[0036] The diameter of the outer silica gel hemisphere 33 is 1 centimeter, and the inner silica gel hemisphere 32 and the outer silica gel hemisphere 33 have the advantages of good biocompatibility, softness, non-allergy, mildness to the skin, etc., and the hemispherical design has no sharp corners, which can avoid causing pressure sores or discomfort to the surrounding healthy skin.

[0037] Referring to Figures 3-4As shown in the preferred technical scheme of the embodiment, the outer silica gel hemisphere 33 is provided with uniform flow guide grooves 331 and medicine guide grooves 332 on the outer surface thereof, the flow guide grooves 331 and the medicine guide grooves 332 are arranged at intervals, the flow guide grooves 331 and the medicine guide grooves 332 meet at the same point along the outer surface of the outer silica gel hemisphere 33, and the flow guide grooves 331 are uniformly provided with adsorption micropores which are in communication with the inside of the connecting channel 34.

[0038] In the above technical scheme, when the outer silica gel hemisphere 33 is pressed against the wound surface, the exuded body fluid is guided by the flow guide grooves 331 and then collected, so that the adsorption material arranged in the middle of the inner silica gel hemisphere 32 can collect the body fluid, and the medicine guide grooves 332 can guide and deliver the medicine, so that the medicine can accurately act on the wound surface, which is beneficial to the healing of the wound and can prevent the wound from being infected.

[0039] Referring to Figures 3-4 As shown in the preferred technical scheme of the embodiment, the ring-shaped medicine pad 35 is arranged between the end of the outer silica gel hemisphere 33 and the ring-shaped partition pad 31, and the end of the medicine guide groove 332 extends to the ring-shaped medicine pad 35.

[0040] In the above technical scheme, the ring-shaped medicine pad 35 is impregnated with antibiotics or healing-promoting medicine, and the medicine is accurately delivered to the wound surface by the medicine guide groove 332, which further prevents infection and accelerates the healing of the wound. It should be noted that the through hole arranged in the middle of the dressing layer 2 can compress the ring-shaped medicine pad 35 at the edge of the compression assembly 3, so that the ring-shaped medicine pad 35 is prevented from directly contacting the skin of the patient, and the medicine impregnated in the ring-shaped medicine pad 35 can be continuously and slowly released through the medicine guide groove 332.

[0041] As the preferred technical scheme of the embodiment, the surface of the outer silica gel hemisphere 33 is a non-smooth surface, and the outer silica gel hemisphere 33 is uniformly provided with silica gel protrusions.

[0042] In the above technical scheme, when the outer silica gel hemisphere 33 is compressed against the wound surface, the silica gel protrusions on the outer side of the outer silica gel hemisphere 33 can prevent the wound surface from directly contacting the outer silica gel hemisphere 33, so that a flowable gap is arranged between the outer silica gel hemisphere 33 and the wound surface, which is beneficial to the discharge of body fluid and the penetration of medicine.

[0043] Referring to Figures 3-4 As shown in the preferred technical scheme of the embodiment, the connecting channel 34 is uniformly provided with a rubber sleeve inside, and the rubber sleeve has a conical structure.

[0044] In the above technical scheme, when the body fluid enters the inside of the inner silica gel hemisphere 32 along the connecting channel 34, the body fluid can accurately pass through the rubber sleeve 341 with a conical structure, and the rubber sleeve can prevent the backflow of the body fluid.

[0045] Referring to Figures 5-7As shown, as the preferred technical solution of the embodiment, the rear side of the base layer 1 is provided with a circular hole, and a tearable plate 11 is mounted on the circular hole, and an adhesive layer 111 is arranged on the inner side of the tearable plate 11, and the tearable plate 11 is used to close the inside of the inner silica gel hemisphere 32.

[0046] In the above technical solution, the adhesive layer 111 is a magic tape, the tearable plate 11 is connected with the annular spacer 31 in a magic tape bonding manner, and a pull tape is further mounted on one side of the tearable plate 11, and the pull tape is pulled by medical staff to avoid disassembling the tearable plate 11, so that the adsorption material inside the inner silica gel hemisphere 32 can be replaced.

[0047] Referring to Figures 5-7 As shown, as the preferred technical solution of the embodiment, the rear side of the base layer 1 is further provided with an air inlet 12, and the air inlet 12 is connected with the inside of the sealed cavity.

[0048] In the above technical solution, the air injection pipe can be accurately inserted and matched with the air inlet 12, air is injected into the inside of the sealed cavity through the air inlet 12, and then the gas pressure in the inside of the sealed cavity can be changed, so that the pressure between the outer silica gel hemisphere 33 and the wound surface can be adjusted.

[0049] In combination with the above structure, the medical dressing for compressing a puncture wound surface provided by the application is implemented according to the following steps when working: S1: Dressing positioning and preliminary fixing The medical staff first performs routine disinfection on the puncture wound surface of the patient after the tube is pulled out, and then aligns the dressing layer 2 and the compression assembly 3 with the wound surface through the base layer 1, so that the outer silica gel hemisphere 33 protruding at the front end of the compression assembly 3 is accurately aligned with the puncture point, and the entire dressing is preliminarily fixed on the skin of the patient by using the adhesive structure on the front end surface of the base layer 1.

[0050] S2: Accurate compression and pressure adjustment After the dressing is fixed, the outer silica gel hemisphere 33 is stretched into and embedded in the inside of the wound surface under the elastic action of the base layer 1, so as to realize accurate three-dimensional compression on the puncture channel under the skin, and physically block the main path of body fluid exudation; if it is necessary to adapt to wound surfaces of different depths or bleeding risks, an air injection pipe can be connected to the air inlet 12 on the rear side of the base layer 1, and a proper amount of gas is filled into the sealed cavity between the inner silica gel hemisphere 32 and the outer silica gel hemisphere 33, so as to change the compression force of the outer silica gel hemisphere 33 on the wound surface by adjusting the pressure in the cavity, and realize the controllability of the compression force.

[0051] S3: Liquid exudation guiding and adsorption collecting At the same time of compression, if a small amount of body fluid seeps out, it will be collected through the flow guide groove 331 on the surface of the outer silica gel hemisphere 33, and then enter the connecting channel 34 through the adsorption micropores on the flow guide groove 331. In the connecting channel 34, the rubber sleeve with a conical structure allows the body fluid to flow in one direction, effectively preventing backflow, and the body fluid is finally transported to the inside of the inner silica gel hemisphere 32, where it is absorbed and locked by the superabsorbent polymer, forming a gel and achieving active management and collection of the exudate.

[0052] S4: Drug sustained release and anti-infection and healing promotion At the same time, the antibiotic or healing-promoting drug impregnated in the annular drug pad 35 begins to be released slowly, and the drug is precisely delivered to the wound surface through the drug guide groove 332 connected thereto. This process is synchronized with step S3, and while managing the exudate, the wound is continuously dosed, effectively preventing infection and accelerating wound healing.

[0053] S5: State monitoring and component replacement During the entire use process, medical personnel can judge the adsorption state by observing the properties of the inner silica gel hemisphere 32 area or according to the use time; when the adsorption material needs to be replaced, the tearable plate 11 on the back side of the base layer 1 can be opened by tearing the drawstring, and the adsorption material inside the inner silica gel hemisphere 32 can be replaced, which is simple and convenient to operate.

[0054] It is apparent to those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and range of equivalents of the essential elements of the claims are intended to be embraced therein.
