Description

Technical Field

[0001] The invention belongs to the technical field of medical dressings, in particular to a medical sterile dressing. Background Art

[0002] A dressing, also known as a plaster product, is made of non-woven fabric. The required medicine is applied to the non-woven fabric and then attached to the patient's affected area. The medicine is absorbed by the skin to exert its efficacy and relieve the patient's pain. Medical sterile dressings are a protective product commonly used in wound care. They are widely used because of their ease of use and good wound care effects.

[0003] Among them, the patent with application number CN202310562061.6 discloses a medical sterile dressing, which relates to the field of medical dressing technology, including a substrate layer, a drug layer, an adhesive layer, a heating pack, an inflatable airbag, a silicone frame and a positioning line, wherein the drug layer is arranged inside the adhesive layer, and the drug layer and the adhesive layer are both arranged below the substrate layer. The above scheme is provided by setting a substrate layer, and a drug layer and an adhesive layer are arranged below the substrate layer. When the sterile dressing is used, the adhesive layer can attach the substrate layer to the user's skin surface, and the drug layer can release the drug to the user's skin. The substrate layer is composed of an outer layer and an inner layer, and an easily torn connecting belt is arranged between the outer layer and the inner layer. After the sterile dressing is used, the inner layer and the outer layer can be separated by tearing the connecting belt, and then the inner layer is torn off first, and then the outer layer is slowly torn off, so as to effectively avoid the sterile dressing from pulling the user's skin during the tearing process to cause secondary damage.

[0004] However, although the separate design reduces secondary damage to skin wounds, it is unable to effectively exert a high treatment efficiency when treating wounds at joints. At the same time, when tissue fluid is precipitated from the wound, directly contacting the wound with the patch will cause the drug solution to contact or be isolated from the tissue fluid first, affecting the wound's absorption of the drug solution, resulting in a decrease in the treatment efficiency of the wound with the medical patch, which is not conducive to wound recovery. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems. The present invention provides a medical sterile dressing, which has the advantage of regulating the secretion of sterile dressing liquid according to the bending conditions of human joints.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a medical sterile dressing, comprising a carrier sheet, the carrier sheet comprising a limiting shell, and a medicine storage cavity is provided through the limiting shell, a medicine dressing component is connected to one side of the medicine storage cavity, a connecting component is connected to the other side of the medicine storage cavity, a reinforcing rib is connected to the medicine storage cavity, and the reinforcing rib is connected to the medicine dressing component;

[0007] The dressing assembly includes a gasket, which is connected to the limiting shell, and has a plurality of drug penetration holes formed therethrough. A protective pad is connected to a side of the gasket close to the connecting assembly, and the protective pad is in a raised state;

[0008] The reinforcing ribs are interconnected cavities, and the cavities are filled with non-Newtonian fluid material.

[0009] Preferably, the connecting component comprises a sealing sheet connected to the limiting shell, a connecting groove is formed at one end of the sealing sheet away from the carrier sheet, a plurality of connecting belts are arranged in the connecting groove, and the connecting belts can be turned over in the connecting groove.

[0010] Preferably, the connection assembly further comprises a plurality of ventilation holes, the ventilation holes are located in the connection groove, and the connection belt can cover the ventilation holes.

[0011] Preferably, a limiting portion is connected to one end of the limiting shell, and the limiting portion and the medicine compress assembly are located on the same side of the limiting shell.

[0012] Preferably, the medicine storage cavity is filled with medicine liquid.

[0013] Preferably, the gasket is a cotton material of an anti-adhesive tape, and the drug infiltration hole is in a closed state under the compression of the gasket.

[0014] Preferably, a protective layer is connected to one end of the gasket close to the connecting assembly.

[0015] Preferably, an adhesive layer is provided on the end of the connecting belt that is not in contact with the vent hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The reinforcing ribs are connected to the gaskets, and the ductility of the gaskets is improved by the setting of the reinforcing ribs, so that the gaskets can fully contact with the wounds, ensuring that the liquid medicine can fully contact with the wounds through the gaskets. At the same time, the reinforcing ribs are used to limit the bending degree of the human joints, so that the elastic changes of the reinforcing ribs are achieved and then adjusted according to the bending rate of the human joints, so as to avoid secondary injuries to the wounds at the human joints, thereby using medical patches to further improve the efficiency of wound healing.

[0018] 2. By utilizing the coordination between the gasket, the drug infiltration hole and the drug storage cavity, it can be ensured that the gasket first absorbs and cleans the wound site to ensure that the wound site is dry, while also ensuring that the drug solution can fully contact the wound. After the gasket dries the wound site, the bending of the human joints is utilized to drive the gasket to bend, thereby causing the drug infiltration hole to open, allowing the drug solution in the drug storage cavity to be discharged, and then the gasket is used to apply the drug to the wound site. In this process, the treatment efficiency of the drug solution and the wound site can be improved.

[0019] 3. The connecting belt and the vent holes are provided to connect the medical patch to the human skin, thereby improving the closeness of the medical patch to the human body. At the same time, when the connecting belt closes the vent holes, a negative pressure state is easily formed in the drug storage cavity, and the drug solution will not leak, thereby improving the use of the medical patch.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 3 As shown, a medical sterile dressing includes a carrier sheet 1, which is a bearing part for carrying the dressing and contacting the human body. The carrier sheet 1 includes a limiting shell 101, wherein one end of the limiting shell 101 close to the dressing component 3 is coated with a gelatin layer, and the limiting shell 101 can be in contact with and adhere to the human skin through the adhesion of the gelatin layer to prevent the medical sterile dressing from falling off, and the gelatin layer on the limiting shell 101 is preferably a medical paper tape, which can meet the fit between the limiting shell 101 and the human body, and can also be used for limiting the skin. When the limiting shell 101 is removed, the colloid layer on the limiting shell 101 is reduced to pull the human skin, thereby preventing secondary damage to the wound, and a drug storage cavity 102 is provided through the limiting shell 101, wherein the drug storage cavity 102 can store the liquid medicine used for the medical sterile dressing, and then when the medical sterile dressing is used, the liquid medicine in the drug storage cavity 102 can be controlled to replenish the dressing component 3, thereby improving the use efficiency of the medical sterile dressing, and one side of the drug storage cavity 102 is connected to the dressing component 3, so that the dressing The component 3 is in contact with the wound, and the dressing component 3 is used to absorb the tissue fluid secreted by the wound, and at the same time, the dressing component 3 is used to treat the wound with anti-inflammatory medicine. The other side of the medicine storage cavity 102 is connected with a connecting component 5, and the space of the medicine storage cavity 102 is closed by the connecting component 5 and the dressing component 3. The connecting component 5 can increase the connection tightness between the limiting shell 101 and the wound. At the same time, when the application is located in an uneven area, the connecting component 5 can increase the connection tightness between the carrier sheet 1 and the body surface to avoid the limiting shell 101 from falling off when the human body continues to move. A reinforcing rib 6 is connected in the medicine storage cavity 102, wherein the reinforcing rib 6 can enhance the ductility of the dressing component 3 to ensure that the dressing component 3 is fully in contact with the wound, and when the dressing component 3 is bent and deformed, the reinforcing rib 6 can effectively buffer the squeezing force on the wound during its deformation, thereby improving the recovery efficiency of the wound, and the reinforcing rib 6 is connected to the dressing component 3, thereby improving the use efficiency of the dressing component 3.

[0030] like Figure 4-Figure 6As shown, in order to ensure that the dressing component 3 can effectively treat the wound, the dressing component 3 includes a gasket 301, wherein the gasket 301 can contact with human skin, and the gasket 301 can absorb the secretions of the human wound, and can also absorb the liquid medicine and transfer it to the wound for treatment, the gasket 301 is connected to the limiting shell 101, and the reinforcing rib 6 and the gasket 301 are connected to each other to ensure that the gasket 301 will not fold, and the gasket 301 is a cotton material of the anti-adhesive tape, and when the gasket 301 contacts the wound , the gasket 301 will not adhere to the wound, which will affect the healing of the wound. A number of drug infiltration holes 302 are formed on the gasket 301, and the drug liquid in the drug storage cavity 102 is transported through the drug infiltration holes 302, so as to replenish the drug liquid components on the gasket 301. At the same time, when the gasket 301 is used, in order to prevent the tissue fluid secreted from the wound from interfering with the drug liquid components, the drug infiltration holes 302 are in a closed state under the pressure of the gasket 301. When the wound is still secreting tissue fluid, the drug liquid does not seep out through the drug infiltration holes 302. The secreted tissue fluid is only absorbed by the gasket 301 to keep the wound dry. A protective layer is connected to one end of the gasket 301 close to the connecting component 5. The protective layer is used to block the drug solution to prevent the drug solution from penetrating before the gasket 301 absorbs all the tissue fluid. It should be noted that the protective layer will not block the drug seepage hole 302, but when the gasket 301 is not deformed, the walls of the drug seepage hole 302 are in contact with each other, which means that the protective layer can block the drug seepage hole 302 to prevent the drug solution from leaking, and A protective pad 303 is connected to one side of the gasket 301 close to the connecting component 5, so as to protect and reduce shock at the joints of the human body to prevent secondary injuries. The protective pad 303 is in a convex state, and when the user of the sterile dressing is using it, the joint bending will drive the protective pad 303 to bend, and at the same time drive the gasket 301 to extend, so that the originally closed drug penetration hole 302 is opened, and the drug liquid in the drug storage cavity 102 moves to the gasket 301 through the drug penetration hole 302, so as to replenish the drug liquid components on the gasket 301.

[0031] The material of the protective layer is preferably a medical waterproof breathable membrane, such as a non-woven PE breathable membrane.

[0032] like Figure 4As shown, the reinforcing ribs 6 are interconnected cavities, and the cavities are filled with non-Newtonian fluid materials, wherein the non-Newtonian fluid materials here include materials that do not cause harm to the human body and are easy to store, and no excessive restrictions are made here. Then, when the gasket 301 is slowly bent, the reinforcing ribs 6 will deform normally, thereby maintaining the tightness of the fit between the gasket 301 and the wound. When the gasket 301 bends rapidly under the influence of the human joints, the strength of the reinforcing ribs 6 is increased under the action of the non-Newtonian fluid material, and the bending angle of the reinforcing ribs 6 is reduced, thereby reducing the bending angle of the gasket 301. At the same time, under the support of the reinforcing ribs 6, the bending angle at the human joints can be appropriately reduced, thereby reducing the tension change of the human skin and reducing the tearing of the human skin wound, avoiding secondary damage to the wound and improving the healing rate of the wound.

[0033] like Figure 5 As shown, in order to avoid leakage of the medicine in the medicine storage cavity 102 and increase the tightness of the connection between the sterile dressing and the human body, further, the connecting component 5 includes a sealing sheet 501, and the sealing sheet 501 is connected to the limiting shell 101, so as to ensure that the medicine storage cavity 102 forms a relatively closed space, which is convenient for storing the medicine. A connecting groove 5011 is provided at the end of the sealing sheet 501 away from the carrier sheet 1, and a plurality of connecting belts 502 are arranged in the connecting groove 5011, and the connecting belt 502 can be turned over in the connecting groove 5011, and the connecting groove 5011 is used to provide a storage position for the connecting belt 502, and the connecting belt 502 is completely placed in the connecting groove 5011, so as to ensure the overall beauty of the medical dressing. At the same time, when the connecting belt 502 is located in the connecting groove 5011, the strength of the connecting component 5 can be increased, and when the medical dressing is bent under force, the deformation degree of the sterile dressing can be adaptively reduced under the action of the connecting belt 502.

[0034] It should be noted that one end of the connecting belt 502 is fixedly connected to the groove wall of the connecting groove 5011, and the other end of the connecting belt 502 is adhered to the bottom of the connecting groove 5011 to ensure the tightness of the connection between the connecting belt 502 and the connecting groove 5011.

[0035] like Figure 5As shown, in order to ensure that the sterile medical dressing will not cause secondary infection of the wound during use, it is necessary to ensure the air permeability at the wound location. The connecting component 5 also includes a plurality of vents 503, so that in the process of the medical dressing contacting the human body, the vents 503 can be used to ensure that the wound is always in an aerobic state to avoid further deterioration of the wound. The vents 503 are located in the connecting groove 5011, and the connecting belt 502 can cover the vents 503, and then the opening and closing of the vents 503 can be controlled by the setting of the connecting belt 502 to ensure that the wound can be healed at a faster rate. The joint 102 is then restored to normal state, that is, when the wound is in the stage of tissue fluid secretion, the medicine in the medicine storage cavity 102 has not penetrated onto the gasket 301. At this time, the connecting belt 502 is connected in the connecting groove 5011 to seal the position of the vent 503. When the medicine in the medicine storage cavity 102 begins to penetrate the gasket 301 through the medicine penetration hole 302, it means that the joint can bend, and then the connecting belt 502 is used to constrain and fix the skin at the edge of the application, and at the same time, the vent 503 is opened to keep the wound in an aerobic environment at all times to prevent the wound from deteriorating.

[0036] Furthermore, by providing the vent hole 503, the air pressure in the medicine storage cavity 102 can be made the same as the external air pressure, so that when the medicine liquid penetrates the gasket 301, the negative pressure in the medicine storage cavity 102 will not cause the medicine liquid to be unable to move, thereby ensuring the normal use of the sterile dressing.

[0037] One end of the limiting shell 101 is connected to a limiting portion 2, wherein in the present embodiment, the material of the limiting portion 2 is preferably soft rubber, so that when the limiting portion 2 contacts the human skin, it will not cause discomfort or wear to the human skin, and the limiting portion 2 and the dressing assembly 3 are located on the same side of the limiting shell 101, wherein in the present embodiment, the shape of the limiting portion 2 is the same as the shape of the bone and the skin, so that when the limiting shell 101 contacts the human skin, the limiting portion 2 can be highly fit with the human skin, so that the gasket 301 contacts the wound, and the gasket 301 will not exert a large squeezing force on the wound, thereby ensuring the dryness of the wound.

[0038] The medicine storage cavity 102 is filled with liquid medicine, wherein the liquid medicine components include but are not limited to liquid for anti-inflammatory, liquid medicine for promoting rapid wound healing, and other liquid medicines that are helpful for wound recovery.

[0039] like Figure 7 As shown, an adhesive layer is provided at one end of the connecting belt 502 that is not in contact with the vent hole 503 , and the surface of the adhesive layer is always covered with a sticker when it is not in contact with human skin to prevent the adhesive layer from adhering to other impurities and affecting the use of the connecting belt 502 .

[0040] During operation, the medical sterile dressing is taken out so that the gasket 301 is facing the patient's wound, and then the gasket 301 contacts the wound. At the same time, the limiting part 2 contacts and clamps with the human skin to ensure the contact degree between the gasket 301 and the patient's wound. At the same time, the pad 303 contacts the joint bend, thereby reducing the friction between the joint bend and the gasket 301. At this time, the gelatin layer on the limiting shell 101 contacts and bonds with the outer skin of the human body to achieve preliminary restriction on the position of the medical sterile dressing. At this time, since the human joints are not bent, the drug penetration hole 302 is always in a closed state, ensuring that the drug solution in the drug storage cavity 102 will not penetrate.

[0041] And when the human joint is not bent, the gasket 301 absorbs the tissue fluid released from the wound to ensure that the wound is always in a relatively dry state. When the human body needs to move, the connecting belt 502 is first moved out of the connecting groove 5011, and then the connecting belt 502 is controlled to adhere to the human skin at the joint to prevent the medical sterile dressing from deviating from the position. After the connecting belt 502 contacts the human skin, the vent 503 is in an open state to ensure that the drug seepage hole 302 can normally discharge the drug liquid in the drug storage cavity 102.

[0042] After ensuring that the connecting belt 502 constrains the position of the application, the human body joints are slightly bent, thereby prompting the gasket 301 to bend, ensuring that the drug infiltration hole 302 is opened, so that the drug liquid in the drug storage cavity 102 seeps out through the drug infiltration hole 302, prompting the gasket 301 to be immersed in the drug liquid to achieve wound treatment. At the same time, after the drug infiltration hole 302 is opened for a while, the human body joints return to the vertical state, and the drug infiltration hole 302 is re-closed, so that the drug liquid can fully contact the wound position, and in the process of drug infiltration through the drug infiltration hole 302, the drug liquid in the drug storage cavity 102 will not be completely precipitated, ensuring the subsequent drug liquid to replenish the gasket 301.

[0043] Then, the human body joints bend and move, causing the drug seepage hole 302 to open and close reciprocally, thereby intermittently replenishing the drug solution in the gasket 301, thereby ensuring that the drug solution in the gasket 301 can fully contact the wound and will not leak. This ensures that the gasket 301 can always be in a moist state, and when the drug seepage hole 302 replenishes the drug solution on the gasket 301, it can quickly penetrate according to the drug solution content on the gasket 301, ensuring that the wound can always be in contact with the drug solution on the gasket 301.

[0044] In the process of bending human joints, small bending can promote the wound to recover at a faster speed, and in this process, it can effectively reduce the situation that the wound is torn due to the lack of elasticity at the scab position after the scab is formed. However, when the dressing is applied to the wound, if the human joint is bent greatly at this time, the wound is easily torn, and then the reinforcing ribs 6 are used to support the strength of the gasket 301, that is, when the gasket 301 is in contact with the wound, the strength of the reinforcing ribs 6 can meet the flatness of the gasket 301, ensuring that the gasket 301 and the wound can be fully attached, thereby improving the efficiency of the medical sterile dressing on the wound, and when the human joint is bent, The non-Newtonian fluid in the reinforcing rib 6 can ensure that the bending rate of the human joint is slow during bending, avoiding secondary tearing of the wound, and the mutual cooperation between the reinforcing rib 6 and the gasket 301 can ensure that the bending amplitude of the human joint is always within a safe range. At the same time, the penetration rate of the liquid medicine in the drug storage cavity 102 can be regulated to ensure that the liquid medicine applied on the patch can fully act on the wound location. When the human joint bends rapidly, the non-Newtonian fluid in the reinforcing rib 6 is subjected to a faster squeezing force, which reduces the elasticity of the reinforcing rib 6, thereby limiting the bending amplitude of the gasket 301, thereby reducing the bending amplitude of the human joint and ensuring that the wound will not suffer secondary damage.

[0045] At the same time, when the patch is used, the connecting belt 502 is first separated from the human skin, and then the limiting shell 101 is removed from the human wound to reduce the situation where the skin is pulled when the patch is removed, causing secondary damage to the wound.

[0046] The reinforcing ribs 6 are connected to the gasket 301, and the ductility of the gasket 301 is improved by the setting of the reinforcing ribs 6, so that the gasket 301 can fully contact the wound, ensuring that the medicine can fully contact the wound through the gasket 301, and at the same time, the reinforcing ribs 6 are used to limit the bending degree of the human joints, so that the elasticity of the reinforcing ribs 6 can be changed and then adjusted according to the bending rate of the human joints to avoid secondary damage to the wounds at the human joints, thereby further improving the efficiency of wound healing by using medical patches.

[0047] On the other hand, the present invention also includes a method for using a medical sterile dressing, comprising the following steps:

[0048] S1. Make the gasket 301 face the wound, and control the gasket 301 to contact the wound on the human body, so as to ensure that the gasket 301 can completely cover the wound and improve the effectiveness of the medical dressing;

[0049] S2, making the limiting shell 101 adhere to the skin around the wound to maintain the position of the carrier sheet 1 stable;

[0050] S3, using the gasket 301 to absorb the tissue fluid precipitated from the wound position, ensuring that there is no tissue fluid at the wound position to block the contact between the liquid medicine and the wound, and ensuring that the wound position is dry;

[0051] S4, removing the connecting belt 502 from the connecting groove 5011, so that the connecting belt 502 is turned over and adhered to the human skin, so as to prevent the medical patch from falling off during the bending of the human joint;

[0052] S5. Control the bending of human joints so that the gasket 301 bends to open the drug penetration hole 302, thereby prompting the gasket 301 to treat the wound location.
