Embodiment 1

[0024] Such as Figure 1-3 As shown, a wheelchair cushion device for preventing sitting sores comprises a cushion frame 1 and an air pumping mechanism 2. Grid-shaped load-bearing tubes 11 are distributed vertically and horizontally in the cushion frame 1, and the load-bearing tubes 11 are fixedly connected to the inner side wall of the cushion frame 1. The side wall of the load-bearing pipe 11 is provided with air holes 111, and the air holes 111 are evenly distributed in the middle part of the cushion frame 1; Strip-shaped setting, the air extraction box 21 can be fixedly installed on the wheelchair seat bottom, and one end of the air extraction box 21 is open and set, and the sliding seal in the air extraction box 21 is connected with a piston plate 211.

[0025] A mounting bracket 212 is fixedly connected to the outer wall of the air extraction box 21, and a rotating shaft 213 is rotatably connected to the mounting bracket 212. The rotating shaft 213 can be driven by a moto...

Embodiment 2

[0028] Such as Figure 4-8 As shown, the difference between this embodiment and Embodiment 1 is: the lower end of the cushion frame 1 is fixedly connected with a base 5, the edge of the base 5 is flush with the cushion frame 1, and a cavity 51 is provided in the base 5, and the cavity 51 There are a plurality of massage parts 52 inside, and the upper end of the cavity 51 is provided with a plurality of sliding holes corresponding to the gaps between the grid-shaped load-bearing tubes 11. The massage parts 52 are massage sticks 521, and the massage sticks 521 are slidably and tightly connected to the sliding holes. Inside, the massage stick 521 is provided with an annular limit slot 522, and the massage stick 521 is slidably connected with the sliding hole through the annular limit slot 522, and the upper end of the massage stick 521 is a circular protrusion 523, which can improve the massage effect. The cavity 51 communicates with the pumping box 21 through the sealing tube 6....

Abstract

The invention belongs to the field of medical equipment, particularly relates to an anti-sitting-sore wheelchair cushion device. The anti-sitting-sore wheelchair cushion device comprises a cushion frame and an air pumping mechanism, wherein latticed load-bearing pipes are vertically and horizontally distributed in the cushion frame; air holes are formed in the side walls of each load-bearing pipe;the air pumping mechanism comprises an exhaust chamber and a driving piece arranged in the exhaust chamber; the load-bearing pipes communicate with the exhaust chamber through a one-way air inlet pipe; and a one-way exhaust pipe which communicates with outside is fixedly connected to the exhaust chamber. According to the anti-sitting-sore wheelchair cushion device disclosed by the invention, theair pumping mechanism is arranged, and air holes are formed in each load-bearing pipe, so that air at the cushion can be continuously pumped, air at the cushion is under a circulation state, the situation that the buttocks of a user are damp and hot can be effectively relieved, and the situation that the user sits on the wheelchair for a long term and is subjected to sitting sores is avoided; elastic corrugated pipes and a cavity are arranged, so that when the air pumping mechanism continuously operates, massaging rods can be driven to continuously move up and down to massage the buttocks of the user, the effects of stimulating the circulation of the blood and causing the muscles and joints to relax are achieved, and the effect of preventing the sitting sores is further achieved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a wheelchair cushion device for preventing sit sores. Background technique [0002] Canker sores, also known as pressure ulcers and decubitus ulcers, are caused by long-term pressure on local tissues, resulting in persistent ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. It is the most common disease in long-term bedridden or long-term paralyzed patients. [0003] The existing wheelchair cushion has a simple structure and a single function. During use, the air permeability between the user's buttocks and the seat cushion is not good, resulting in the accumulation of hot and humid air, which cannot be circulated in time, and the user's buttocks are under pressure for a long time. The blood cannot circulate, and the situation of sitting sores is very easy to occur. [0004] For this reason, we propose a kind of anti-sit sore wheelchai...
