Description

TECHNICAL FIELD

[0001] The present application relates to the field of pressure ulcer prevention pad cutters, in particular to a pressure ulcer prevention pad cutter for high pressure oxygen breathing tubes. BACKGROUND

[0002] Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves the inhalation of high concentrations of oxygen in an environment above one atmosphere of pressure to treat various hypoxic diseases and related conditions.

[0003] In hyperbaric oxygen therapy, the breathing tube is a key component that connects the patient to the oxygen supply system of the hyperbaric oxygen chamber. However, the existing high pressure oxygen breathing tube is prone to causing pressure on the patient's skin during long-term use, leading to discomfort and even skin damage and the development of pressure ulcers, especially for newborns and infants whose skin is particularly delicate.

[0004] To solve this problem, medical staff often use hydrocolloid dressings and other dressings to reduce pressure, but these dressings often need to be cut into specific shapes to fit the contact area between the breathing tube and the patient's skin. However, manually cutting the dressings is inefficient, and the edges of the cut surface are not easy to smooth, which can irritate the patient's skin. When there are a large number of patients, it takes a lot of time. CONTENT OF THE INVENTION

[0039] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as they do not conflict with each other.

[0040] The utility model provides aFigures 1 to 5 The cutter for high-pressure oxygen breathing tube pressure sore prevention pad aims to solve the low cutting efficiency of the existing high-pressure oxygen breathing tube pressure sore prevention pad.

[0041] The cutter for high-pressure oxygen breathing tube pressure sore prevention pad mainly comprises a base 100, a pressing seat 200 and a cutter 300. The pressing seat 200 has a cutting surface facing the base 100, the cutter 300 is arranged on the cutting surface, and the pressing seat 200 is arranged separately from the base 100. The base 100 is used for positioning the dressing, the pressing seat 200 is driven to move towards the base 100, and the cutter 300 is used for cutting the dressing on the base 100.

[0042] Specifically, the dressing is arranged on the surface of the base 100 facing the pressing seat 200, and the dressing is arranged parallel to the cutting surface. When the pressing seat 200 is driven to move towards the base 100, the cutter 300 first contacts the dressing. When the pressing seat 200 continues to be driven to move towards the base 100, the cutter 300 can cut the dressing into a specific shape, replacing the manual trimming work of the dressing.

[0043] The cutter 300 comprises a first cutter 310 and a second cutter 320. The first cutter 310 is arranged on the cutting surface, and the second cutter 320 is arranged on the cutting surface in a sliding direction facing or away from the first cutter 310. The second cutter 320 is arranged on the cutting surface in the sliding direction. The first cutter 310 and the second cutter 320 form a cutting area.

[0044] It should be noted that the pressure sore prevention pad is, for example, Figure 5 as shown in the specification, wherein the middle part of the pressure sore prevention pad is attached to the middle part of the patient's face, and the two ends of the pressure sore prevention pad are attached to the cheek parts of the patient. Therefore, in order to better protect the skin of the patient, the length a of the pressure sore prevention pad is preferably the width of the patient's middle part.

[0045] Specifically, the first cutting knife 310 and the second cutting knife 320 are a cutting area, when the dressing is cut by the first cutting knife 310 and the second cutting knife 320, the pressure ulcer pad is located in the cutting area, by driving the second cutting knife 320 to slide along the sliding direction, the distance between the first cutting knife 310 and the second cutting knife 320 can be controlled, and the length a of the pressure ulcer pad can be controlled by controlling the distance between the first cutting knife 310 and the second cutting knife 320. Therefore, in the actual use process, the distance between the first cutting knife 310 and the second cutting knife 320 can be adjusted according to the width of the patient's urethra for different patients, so that the pressure ulcer pad can be adapted to different patients. At the same time, in order to better take out the pressure ulcer pad in the cutting area from the original dressing, the length of the first cutting knife 310 and the second cutting knife 320 can be lengthened, and the length of the first cutting knife 310 and the second cutting knife 320 is greater than the length of the dressing, so that the whole dressing can be cut off when the first cutting knife 310 and the second cutting knife 320 are used to cut the dressing, so that the pressure ulcer pad is completely separated from the original dressing.

[0046] To solve this problem, medical staff usually uses hydrocolloid dressing to reduce pressure, but these dressings often need to be cut into a specific shape to adapt to the contact area between the breathing tube and the patient's skin. Artificial cutting of the dressing is low in efficiency, and the edge surface is not easy to smooth, which can easily irritate the patient's skin, and when the number of patients is large, a lot of time is needed.
