Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a water bag for preventing pressure sores. Background Art

[0002] Pressure ulcers, also known as pressure sores or bedsores, are caused by prolonged localized pressure on tissue, leading to persistent ischemia, hypoxia, and malnutrition, which can lead to tissue ulceration and necrosis. Since most patients lie flat on their beds after surgery, prolonged pressure on their buttocks can easily lead to pressure ulcers. This is a common problem in postoperative rehabilitation and nursing care. However, as the demand for patient care in medical departments continues to increase, the shortcomings in ulcer prevention during rehabilitation and nursing care are in urgent need of improvement.

[0003] In the existing technology, the common anti-pressure sore pads on the market generally adopt an inflatable air cushion structure. This air cushion structure is not only unable to be flexibly adjusted and moved, but also has poor air permeability. Long-term use will still cause poor blood circulation and hypoxia in the patient's buttocks, thereby leading to the formation of pressure sores and affecting the patient's recovery effect. For this reason, we have made improvements and proposed a water bag for preventing pressure sores. Utility Model Content

[0004] (1) Technical issues to be solved

[0005] In order to solve the above problems of the prior art, the utility model provides a water bag for preventing pressure sores, which solves the problem that the poor air permeability of traditional seat cushions can easily cause poor blood circulation and hypoxia in the patient's buttocks.

[0006] (2) Technical solution

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model are:

[0008] A water bag for preventing pressure sores comprises a water bag with a hollow interior, the middle portion of the water bag being concave inward in an arc shape, the middle portion of the water bag being provided with a support portion, the middle portion of the support portion being provided with a circular mounting groove, an elastic support component being installed inside the circular mounting groove, sponge pads being provided on both sides of the water bag surrounding the support portion, a ventilation groove being provided at the bottom of the water bag along the length direction, the sponge pads and the ventilation groove being connected to form a ventilation area.

[0009] The side wall of the water bag is connected with a water injection pipe, and one end of the water injection pipe is threadedly connected with a sealing plug.

[0010] The support portion is made of one of rubber and silicone, and the height of the support portion is smaller than the height of the edges at both ends of the water bag.

[0011] A plurality of first channels are provided inside the sponge pad, a second channel is provided at the bottom of the water bag, and the first channels are communicated with the second channels.

[0012] The elastic support component includes a support platform, a hemispherical groove is opened on the top of the support platform, a support ball is embedded in the hemispherical groove, and the support platform and the water bag are elastically matched through an elastic component.

[0013] The support ball is made of rubber, and is loosely fitted with the support platform. The elastic component is a spring, one end of the spring is fixedly connected to the support platform, and the other end of the spring is fixedly connected to the water bag.

[0014] (3) Beneficial effects

[0015] The beneficial effects of the utility model are as follows: through the arrangement of the water bag, the support part, the sponge pad, the elastic support component, the breathable groove and the breathable area, the water bag can be inflated to form a support structure after being filled with water, and a person can sit on the water bag. When providing support, the sponge pad can improve the comfort of contact, and at the same time, the sponge pad is connected with the breathable groove, and the air flow can enter the breathable area formed by the sponge pad through the breathable groove, thereby improving the comfort. At the same time, the elastic support component can support the buttocks. When the buttocks move and deviate, the support platform can bend, and the support ball rolls to achieve a massage effect, so that the buttocks are partially in contact with the support part and partially separated from the support part, which is convenient for air flow, thereby avoiding the buttocks from being airtight for a long time and causing pressure sores.

[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 5 As shown, the utility model is a water bag for preventing pressure sores, comprising a hollow water bag 1, the middle part of the water bag 1 is inwardly arc-shaped, the middle part of the water bag 1 has a support part 2, the middle part of the support part 2 is provided with a circular mounting groove 3, the inside of the circular mounting groove 3 is provided with an elastic support component 4, sponge pads 5 are provided around the support part 2 on both sides of the water bag 1, and a ventilation groove 6 is provided at the bottom of the water bag 1 along the length direction, and the sponge pads 5 and the ventilation groove 6 are connected to form a ventilation area. In actual implementation, when water is injected into the water bag 1, a support structure is formed, and a person can sit or stand on the water bag 1. The support part 2 plays the main supporting role, and the elastic support component 4 is embedded in the mounting groove 3, which can support the user in a gap, lift the user's buttocks, form a gap, and facilitate air circulation. At the same time, the sponge pad 5 can improve the comfort of the user, and the ventilation area formed between the ventilation groove 6 and the sponge pad 5 can further realize the circulation of air, thereby improving comfort while preventing the occurrence of pressure sores.
