[0026] The following will be described in detail in combination with the accompanying drawings Figure 1 to the accompanying drawings Figure 5 and specific embodiments.

[0027] The present application discloses a medical dressing shaping die cutting device (hereinafter referred to as "device"), comprising a base 100 which can be placed on a plane, a pressing part 200 and a driving assembly 300, the upper surface of the base 100 is arrayed with a plurality of shaping holes 101, these shaping holes 101 can form a dressing placement area on the same plane, i.e. the upper surface of the base 100, for spreading and laying the dressing to be cut, such as gauze, adhesive plaster, medicine patch, etc. in the dressing placement area; the pressing part 200 is arranged above the dressing placement area, preferably, the pressing part 200 is a plate structure, and the side opposite to the dressing placement area is provided with a mounting hole 203 corresponding to each of the shaping holes 101, i.e. the mounting hole 203 and the shaping hole 101 are on the same vertical line, the device further comprises a punching needle 204, which is detachably arranged in the mounting hole 203, the operator can set the punching needle 204 in the mounting hole 203 based on the shape of the dressing to be cut, so that the points where a plurality of adjacent punching needles 204 are located can be connected to form a dressing shaping pattern; the driving assembly 300 is in transmission connection with the pressing part 200, and the driving assembly 300 is used to drive the pressing part 200 to move along the direction of gravity, so that the punching needle 204 penetrates the dressing placement area and enters the corresponding shaping hole 101.

[0028] Specifically, the distribution density of the above-mentioned shaping holes 101 and mounting holes 203 should at least ensure that after the adjacent punching needles 204 punch the dressing, the operator can easily take the desired pattern along the line where the holes are located. Based on this, different materials of dressings, such as gauze, adhesive bandages and other commonly used medical dressings, can be punched and cut for experiments. During the experiment, different densities of punching needles 204 and different sizes of punching needles 204 are used to punch different materials of dressings. Finally, the spacing of the punching needles 204 that can adapt to different dressings is determined according to the completeness of the edges of the obtained pattern, the difficulty of obtaining the pattern, and other effects. Then, the distribution density of the above-mentioned shaping holes 101 and mounting holes 203 is set within the range of the spacing to ensure that the above-mentioned device can punch and cut one or several dressings of commonly used materials.

[0029] The process of using the above-mentioned device includes the following steps: the operator sets the punching needles 204 of corresponding density in the corresponding mounting holes 203 based on the material of the dressing and the desired pattern, so that the pattern and punching position formed by the punching needles 204 correspond to the dressing placed above the dressing placement area and the shape of the desired pattern; After setting the needles, the dressing is laid out flat and kept in a fixed state on the dressing placement area, and then the pressing part 200 is pressed downward by the driving assembly 300, so that the punching needles 204 penetrate the dressing into the shaping holes 101, so that the punching needles 204 leave continuous pinholes on the surface of the dressing and form the desired pattern, thereby achieving the purpose of cutting the dressing or pre-treating the dressing according to the desired pattern.

[0030] The use of the above-mentioned medical dressing shaping die-cutting device has at least the following beneficial effects:

[0031] After the operator sets the punching needles 204 in the mounting holes 203 corresponding to the points corresponding to the desired pattern, the punching needles 204 penetrate the dressing and leave continuous pinholes on the dressing to form a pattern by pressing the pressing part 200 downward, so that the operator does not need to cut the dressing with scissors, improving the accuracy of cutting the dressing; when there are several dressings of the same shape, the operator only needs to move the dressing to adjust the position of the dressing on the dressing placement area, and then press the pressing part 200 downward intermittently to obtain several dressings of the same shape, improving the efficiency of cutting the dressing, and the operator can adjust the position of the punching needles 204 according to the desired pattern of the dressing to be cut, that is, various shaped patterns can be formed flexibly, thereby avoiding the cumbersome process of replacing the die of the existing die-cutting machine, and reducing the cost of using the equipment.

[0032] In addition, the present application also provides some more specific embodiments to perfect the above-mentioned medical dressing shaping die-cutting device.

[0033] Further, the upper surface of the base 100 is provided with guide posts 102 at the dressing placement area. Specifically, a plurality of guide posts 102 are symmetrically arranged on both sides of the dressing placement area, and the guide posts 102 all extend upward in the vertical direction. The pressing part 200 is slidably sleeved with the guide posts 102 through the through holes penetrating the upper and lower surfaces thereof, so as to guide the pressing part 200 to be driven by the driving assembly 300 to move downward in the direction of gravity, thereby enabling the punching needles 204 corresponding to the positions of the shaped holes 101 to accurately cut the dressing according to the required pattern profile.

[0034] On the basis of the structure of the above embodiment, the guide posts 102 are sleeved with return springs 103 between the base 100 and the pressing part 200. When the pressing part 200 is pressed downward by the manually driven driving assembly 300, the return springs 103 are used to automatically restore the pressing part 200 to the initial position, i.e., to keep the punching needles 204 suspended above the dressing placement area, so that the pressing part 200 can be continuously pressed to cut the dressing in batches.

[0035] In one embodiment, in order to facilitate the operator to quickly replace the positions of the punching needles 204 to obtain dressings of different shapes, the pressing part 200 includes a first fixed plate 201 and a second fixed plate 202. The mounting holes 203 are distributed on the bottom surface of the second fixed plate 202, and the second fixed plate 202 is detachably arranged on the bottom surface of the first fixed plate 201 by screws. The operator can prepare a plurality of identical second fixed plates 202 for backup, and arrange the punching needles 204 in the mounting holes 203 at different positions of the second fixed plate 202, so that the punching needles 204 form different punching patterns on the bottom surface of the second fixed plate 202. When it is necessary to obtain dressings of different patterns or shapes, the operator only needs to loosen the screws, remove the second fixed plate 202, and replace it with another backup second fixed plate 202, so as to replace the punching die and improve the efficiency of replacing the dressing pattern.

[0036] Further, in order to prevent the second fixed plate 202 from being replaced and the punching needles 204 from being inclined or shaken, the mounting holes 203 are arranged in the shape of stepped counterbores, and the upper ends of the punching needles 204 are also matched with the inner wall shape of the mounting holes 203. When the second fixed plate 202 is fixed to the bottom surface of the first fixed plate 201 by screws, each punching needle 204 is tightly matched with the counterbore under the abutting and pressing action of the bottom surface of the first fixed plate 201, so that the punching needles 204 remain in a stable state, in which the punching needles 204 are all perpendicular to the dressing placement area and the needle tips are downward, thereby ensuring the accuracy of cutting the dressing according to the shaped pattern profile.

[0037] Further, to avoid the situation that the pattern is not formed completely or the operator is not convenient to take out the dressing along the needle eye due to the too small needle eye left on the dressing by the punching needle 204, the tip of the punching needle 204 is provided with a cutting hole 2041, specifically, the cutting hole 2041 is a hole with an inner diameter between the maximum diameter and the minimum diameter of the punching needle 204, which can expand the diameter of the needle eye. The cutting hole 2041 pierces the dressing and cuts off part of the dressing within the range of the cutting hole 2041 during the pressing process, so that the dressing can be easily taken out according to the contour of the pattern after being punched.

[0038] In a specific embodiment, the base 100 is further provided with a dressing positioning assembly 400 on both sides of the dressing placement area, which is used to fix the dressing above the dressing placement area to prevent the dressing from moving or wrinkling during the punching and cutting process, thereby affecting the cutting accuracy.

[0039] Specifically, in a preferred embodiment, the dressing positioning assembly 400 includes protrusions 401 symmetrically arranged on both sides of the dressing placement area, which are elongated along the extension direction of the width of the dressing placement area, and the upper surface of the protrusion 401 is provided with a clamping groove 4011 along the length extension direction, and one end of the protrusion 401 is rotatably provided with a clamping strip 402 through a rotating shaft arranged on both sides of the base 100, and the clamping strip 402 and the clamping groove 4011 form a detent cooperation. When the dressing is laid flat on the dressing placement area, the clamping strip 402 is turned down and the two side edges of the dressing outside the dressing placement area are pressed into the clamping groove 4011 through the clamping strip 402, thereby achieving the effect of fixing the dressing and avoiding displacement of the dressing during cutting, thereby improving the cutting accuracy.
