[0002] At present, most patients with skin diseases have skin lesions of varying degrees. For example, toxic epidermal necrolysis (TEN) is a drug-induced life-threatening peeling skin lesion. Its typical skin lesions are diffuse bright red or purple-red patches, blisters, bullae, and positive Nikolsky sign. After being squeezed by external force, the bullae rupture to form a dark red erosive surface, which appears as a second-degree burn-like wound. In addition, patients with pemphigus, pemphigoid, bullous disease, burns, etc. will also suffer from skin lesions of varying degrees when they are ill.

[0003] In the process of clinical nursing, for skin care of patients with skin injuries, in order to avoid further damage to the skin tissue, non-adhesive dressings (such as bandages) are used to avoid damaging the originally intact epidermis. Dressings are used to protect exposed skin areas. To prevent the wound surface from drying out, drugs are repeatedly sprayed on the dressings. To prevent infection, the dressings need to be changed regularly.

[0004] However, the traditional dressing change method requires spraying the prepared medicine on the dressing applied to the affected area. The spray volume is usually small, and there is a disadvantage of rapid evaporation after the dressing change. Frequent dressing changes may cause patients to suffer from unbearable pain and increase the risk of infection, causing patients to feel anxious and nervous and resist treatment.

[0025] like Figure 1-Figure 4 , Figure 7 The figures are schematic diagrams of different structures of the tearable dressing changing device of the present invention, and it can be seen from the figures that the tearable dressing changing device of the present invention comprises: a drum shell 1 with through holes formed on two opposite side walls; a drum shaft 2 with two ends respectively fitted with the through holes on the two opposite side walls of the drum shell; a dressing roll 3 formed by a dressing and mounted on the drum shaft; a containing cylinder 8 for containing a medicinal liquid to be infiltrated into the dressing, which is arranged above the drum shell and corresponds to the position of the drum shaft; a medicinal liquid releasing structure 9 arranged near the opening of the containing cylinder for causing the medicinal liquid contained therein to flow downward onto the dressing; and a blade 7 arranged on the drum shell for cutting off the dressing on which the medicinal liquid is sprinkled.

[0026] Specifically, the drum shell adopts a rectangular parallelepiped shell with a hollowed-out middle portion, and through holes are respectively opened on two opposite side walls corresponding to the hollowed-out positions. The two through holes are through holes, and the two ends of the drum shaft are respectively placed at the through holes (such as Figure 1 As shown in the figure, the roller shaft and the through hole are in clearance fit. When the roller shell is subjected to a downward pressing force and dragged to move on the object, the roller shaft can be subjected to a downward pressing force and dragged by the roller shell to move on the object. Since the dressing roll formed by the dressing is sheathed outside the roller shaft, the dressing on it can be released during the rolling process of the roller shaft. The dressing can be gauze or bandage, etc.

[0027] In order to facilitate the disassembly and assembly of the dressing roll, the drum shell of the utility model can also be manufactured in a split manner and then buckled together, that is, processed into Figure 3 , Figure 4 The two half shells are buckled together to form a complete drum shell. Of course, corresponding convex and concave engaging parts can be processed on the half shells as needed. The separate manufacturing and then buckling together to form a complete shell can be achieved by the existing technical method, which will not be described in detail here.

[0028] A container is arranged above the corresponding hollow portion of the drum shell, and is a conical cylinder with a rectangular cross section (see Figure 2), the container is narrowed from top to bottom to the connection with the drum shell. A liquid medicine release structure 9 is arranged at the opening of the container, and the liquid medicine release structure may include a fixing plate 9b with a through hole fixedly installed in the container (such as Figure 6 ) and a movable plate 9a with through holes (as shown) movably arranged in the container and movable relative to the fixed plate with through holes Figure 5 As shown). During design, the size of the fixed plate with through holes is slightly larger than the size of the movable plate with through holes. The fixed plate can be arranged above or below the movable plate and the two can fit together. The positions of the several through holes 91 on the movable plate and the several through holes on the fixed plate are staggered. Connecting shafts 92 for respectively movably connecting with the side walls of the containing tube are arranged at both ends of the movable plate. The connecting shaft on at least one side extends out of the containing tube. The movable plate is moved relative to the fixed plate by manually pulling the connecting shaft, so that the positions of the through holes on the movable plate and the fixed plate correspond to each other, so that the liquid medicine in the containing tube flows downward through the through holes corresponding to the positions. Alternatively, the positions of the through holes on the movable plate and the fixed plate are staggered and fit together tightly, so that the liquid medicine in the containing tube cannot flow downward through the through holes. After the liquid medicine flows downward, it can flow onto the dressing roll, thereby moistening the dressing. During application, the time interval for pulling the movable plate can be determined according to the required moistening thickness of the dressing on the dressing roll.

[0029] Furthermore, a sealing ring may be provided on the liquid medicine release structure, such as outside the connecting shaft of the movable plate, to prevent leakage of the liquid medicine when the liquid medicine is not required to flow downward. Of course, the liquid medicine release structure may also adopt a structure of the prior art that can rotate relative to the containing cylinder to open the outlet to release the liquid medicine or close the outlet to prevent the liquid medicine from flowing out, which will not be described in detail here.

[0030] In order to facilitate pressing the drum shell, a drum handle 4 is fixedly connected to one end of the drum shell. The handle is in the shape of a long strip, and the cross section can be square or circular. The length is reasonably determined during design for easy gripping. A countersunk hole parallel to the drum axis is opened near the edge of the other end of the drum shell. The length of the countersunk hole is slightly larger than the length of the dressing roll mounted on the drum axis. A blade that can slide along the countersunk hole is placed at the countersunk hole. The dressing that is released by the drum axis and sprinkled with liquid medicine as needed is cut off by the blade so that the dressing can be applied to the patient's skin lesions. Furthermore, a groove can be provided at one end of the countersunk hole of the drum shell to accommodate the blade.

[0031] During manufacturing, two sides of the countersunk hole extending in the length direction are respectively provided with a slide groove 5, a pair of ear plates 6 which can move relative to the slide groove are correspondingly arranged in the pair of slide grooves, and the blade 7 is a paper cutting blade, and the handle end of the blade is rotatably connected with the pair of ear plates through a pin shaft so that the blade can rotate at least 270 degrees around the pin shaft relative to the drum shell. In this way, when it is not necessary to cut the dressing, the blade can be placed in the groove at one end of the countersunk hole for easy storage, and when it is necessary to cut the dressing, the blade is rotated 270 degrees to Figure 1The dotted line shows position 7', where the blade extends downward to align with the dressing for cutting, and then by pushing a pair of ear plates to move in the slide, the blade can pass through the dressing to cut off the dressing to be used from the entire dressing roll.

[0032] Further, such as Figure 7 As shown, the utility model can also be provided with an outlet 11 for the dressing to pass out at the other end of the drum shell near the countersunk hole, so that the end of the dressing will extend from the outlet so as to be cut by a blade arranged near the outlet.

[0033] Furthermore, the utility model can also provide an outer cover (not shown in the figure) on the outer cover of the tearable dressing changing device, and the outer cover can be removed when in use.

[0034] The utility model of the easy-tear skin dressing changing device is convenient for nurses to change dressings while reducing the pain of patients. The relevant medicines to be sprinkled on the bandage are stored in the container above the dressing, and the dressing can be moistened as needed, which is convenient for clinical use. The roller brush structure design is easy to operate, saving a lot of time for applying gauze, and the dressing can be cut to the required length, which is convenient for use.

[0035] Although the utility model is described in detail above, the utility model is not limited thereto, and technicians in this technical field can make modifications based on the principles of the utility model. Therefore, all kinds of modifications made according to the principles of the utility model should be understood to fall within the protection scope of the utility model.
