Description

Technical Field

[0001] This application belongs to the field of medical auxiliary devices, and specifically relates to a dressing cutting device. Background Art

[0002] Non-invasive assisted ventilation connects a nasal mask, a ventilator and a patient through positive pressure support, without the need to establish an invasive artificial airway, and has the advantages of being non-invasive, easy to accept, and having fewer complications. Most patients undergoing non-invasive ventilator-assisted ventilation have critical illnesses and are unable to breathe independently or are accompanied by respiratory failure. Their conditions are relatively serious, and the ventilation treatment time is relatively long. The mask presses on the nasal and facial skin for a long time, which is extremely likely to cause pressure sores, exacerbate the physical and mental discomfort of the patients, and affect the compliance with non-invasive ventilator treatment. Therefore, it is particularly important to prevent the occurrence of pressure sores in patients using non-invasive ventilator-assisted ventilation. Clinically, foam dressings are often used for decompression, and the effect is good. When in use, the cut dressing is gently attached to the patient's nasal and facial area as a whole, and unfolded from the inside out, so that the dressing is evenly attached to the area covered by the mask, avoiding wrinkles and air bubbles, closely attached to the skin pressed by the mask, assisting the patient to correctly wear the anesthesia mask, and connecting the ventilator. However, when cutting the foam dressing, since the cutting methods of each person are inconsistent during cutting, the sizes of the cut dressings are different, the edges are not neat and beautiful enough, and it takes multiple cuts to cut out a suitable hollowed-out part, which is time-consuming; moreover, the cut hollowed-out dressing cannot be consistent with the arc of the inner circle of the non-invasive mask, and cannot fit perfectly, there is a possibility of air leakage or mask displacement, thus affecting the treatment and decompression effects. Utility Model Content

[0003] The purpose of this application is to provide a dressing cutting device that can quickly cut out neat and beautiful foam dressings. To this end, the following technical solutions are adopted in this application:

[0004] A dressing cutting device includes a bottom plate and a pressing plate, and the edges of the two are rotatably connected; a raised retaining strip is provided on the top surface of the bottom plate at the edge, and the area surrounded by the retaining strip is used to place the dressing, and the pressing plate can be stacked on the retaining strip after rotation; a cutting blade is provided on the bottom surface of the pressing plate, and the cutting blade can be placed in the area surrounded by the retaining strip when the pressing plate is stacked on the retaining strip, so as to cut the dressing.

[0005] In at least one embodiment, the cutting blade includes a closed-loop blade, and the closed-loop blade surrounds a closed circle; preferably, the area surrounded by the closed-loop blade is in a water droplet shape. Further, the cutting blade further includes two groups of broken-ring blades, and the broken-ring blades include several arc-shaped blades arranged at intervals and surrounding a circle. The two groups of broken-ring blades are arranged inside the closed-loop blade and are sequentially contracted inward to form two circles with several breaks.

[0006] In at least one embodiment, a pivot assembly is provided at the position where the bottom plate and the pressing plate are rotatably connected. The pivot assembly includes a pivot seat, a rotating rod, and a pivot shaft. The pivot seat includes two bumps respectively fixedly connected to both ends of the edge of the bottom plate, and the bumps protrude above the top surface of the bottom plate. The rotating rod is fixedly connected to the edge of the pressing plate and protrudes downward from the bottom surface of the pressing plate. The lower part of the rotating rod is located between the two bumps and is provided with a through hole. The pivot shaft is fixedly connected between the two bumps and passes through the through hole of the rotating rod.

[0007] Compared with the prior art, the present application has at least the following beneficial effects: The dressing cutting device provided by the present application can quickly cut the dressing into a neat and beautiful specific shape on the bottom plate by setting two bottom plates and pressing plates that can be stacked on top of each other, setting a retaining strip for placing the dressing around on the bottom plate, and setting a cutting blade with a specific shape on the pressing plate, which saves time and effort and improves the work efficiency of nurses. When the cut dressing is used, it can make the mask, dressing, and skin fit together, ensure the stability of the non-invasive mask without displacement, increase the comfort of the patient, and improve the compliance of using the non-invasive ventilator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0016] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0017] like Figures 1 to 5 As shown, in at least one dressing cutting device of the present embodiment, it includes a base plate 100 and a pressing plate 200, and the edges of the two are rotatably connected; the top surface of the base plate 100 is provided with a raised enclosure strip 110 at the edge, and the area surrounded by the enclosure strip 110 is used to place the dressing, and the pressing plate 200 can be stacked on the enclosure strip 110 after rotation; the bottom surface of the pressing plate 200 is provided with a cutting blade 300, and the cutting blade 300 can be placed in the area surrounded by the enclosure strip 110 when the pressing plate 200 is stacked on the enclosure strip 110, so as to cut the dressing.

[0018] The bottom plate 100 and the pressing plate 200 can be made of PVC, which has the advantages of tensile strength, bending strength, compression strength and impact resistance, can be used for a long time and is not easy to be damaged. The area inside the enclosure strip 110 is generally 10 cm×10 cm or slightly larger than this area, so that it can be used to place a 10 cm×10 cm foam dressing (such as Mepilex Swedish self-adhesive soft silicone ordinary foam dressing, model 294100).

[0019] In addition, a cushion layer 120 is laid on the top of the bottom plate 100, and the cushion layer 120 is located in the area surrounded by the enclosure strips 110. The cushion layer 120 can be made of rubber material and is used as a buffer layer to prevent the cutting blade 300 from being passivated after long-term use.

[0020] In addition, the pressing plate 200 is provided with a side-convex pressure-assisting sheet 210 at the edge of the non-rotating connection. The upper and lower surfaces of the pressure-assisting sheet 210 are provided with grooves 211. In this way, it is convenient to move the pressing plate 200 by hand through the pressure-assisting sheet 210.

[0021] like Figures 1 to 3As shown, the cutting blade 300 at least includes a closed-loop blade 310, which surrounds to form a closed circle; moreover, the area surrounded by the closed-loop blade 310 is in a teardrop shape. Compared with the conventional "diamond" - shaped dressing cutting method, since the hollow part at the lower edge of the "diamond" dressing is relatively narrow, it presses on the corners of the mouth, affecting the comfort of the patient. Moreover, the "diamond" - shaped hollow dressing cut cannot be consistent with the "teardrop - shaped" arc of the inner circle of the non - wound mask and cannot fit perfectly, which may cause air leakage or mask displacement, thus affecting the treatment and decompression effects. After using the closed - loop blade 310, a teardrop - shaped dressing can be cut, effectively solving this drawback.

[0022] Reference can also be made to Figure 4 , in another embodiment, the cutting blade 300 further includes two groups of broken - ring blades 320. The broken - ring blades 320 include several arc - shaped blades arranged at intervals and surrounding to form a circle. The two groups of broken - ring blades 320 are arranged inside the closed - loop blade 310 and sequentially contract inward to form two circles with several breaks. Preferably, the width of the broken - ring blade 320 is smaller than the width of the closed - loop blade 310 to prevent the cut marks formed on the dressing from completely penetrating and avoid air leakage. After using the cutting blade 300, a dressing shape 500 as shown in Figure 5 can be cut. In this way, two successively shrinking teardrop - shaped cut marks can be distributed in a large teardrop - shaped dressing. Thus, according to the different body types or ages of the patients, by cutting along the solid lines and dotted lines inside the figure, three different - sized dressings can be obtained while ensuring that the shape is basically neat. Generally, they can be respectively applicable to adults, children, and infants.

[0023] Continue to refer to Figures 1 to 3 , in an alternative embodiment, a specific example of a rotational connection is provided. Specifically, the bottom plate 100 and the pressing plate 200 are provided with a pivot assembly 400 at the edge of the rotational connection. The pivot assembly 400 includes a pivot seat 410, a rotating rod 420, and a pivot shaft 430; the pivot seat 410 includes two protrusions respectively fixedly connected to both ends of the edge of the bottom plate 100, and the protrusions protrude above the top surface of the bottom plate 100; the rotating rod 420 is fixedly connected to the edge of the pressing plate 200 and protrudes below the bottom surface of the pressing plate 200. The lower part of the rotating rod 420 is located between the two protrusions and is provided with a through - hole; the pivot shaft 430 is fixedly connected between the two protrusions and passes through the through - hole of the rotating rod 420. This structure can not only achieve the rotational connection between the bottom plate 100 and the pressing plate 200, but also, due to the design of the upward protrusion of the pivot seat 410 and the downward protrusion of the rotating rod 420, the enclosure strip 110 does not affect the smooth rotation, and ensures that the pressing plate 200 can be stacked flat and stably on the top of the enclosure strip 110, ensuring the smooth progress of cutting.

[0024] It should be understood that all of the above embodiments are exemplary rather than restrictive. Those skilled in the art, under the concept of this application, any modifications or deformations made to the specific embodiments described above should fall within the protection scope of this application.
