Description

A wheelchair cushion device for preventing scabies

technical field

The invention belongs to the field of medical equipment, and in particular relates to a seat cushion device for a wheelchair for preventing acne.

Background technique

Canker sores, also known as pressure ulcers and bedsores, are the most common disease among long-term bedridden or chronically paralyzed patients due to long-term pressure on local tissues, resulting in persistent ischemia, hypoxia, and malnutrition.

The existing wheelchair seat cushion is simple in structure and single in function. During use, the air permeability between the user's buttocks and the seat cushion is poor, 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 it is very easy to cause acne.

To this end, we propose an anti-sore wheelchair cushion device to solve the above problems.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the problem of poor ventilation effect of the existing wheelchair cushions, and to provide a wheelchair cushion device with good ventilation effect and massage effect.

In order to achieve the above purpose, the present invention adopts the following technical solutions: an anti-sore wheelchair cushion device, comprising a cushion frame and an air extraction mechanism, wherein grid-shaped load-bearing tubes are distributed vertically and horizontally in the cushion frame, and the The side wall is provided with air holes; the air extraction mechanism includes an air extraction box and a driving member arranged in the air extraction box, the load-bearing pipe is communicated with the air extraction box through a one-way air intake pipe, and the air extraction box is fixed on the air extraction box. A one-way exhaust pipe communicating with the outside is connected.

In the above-mentioned anti-sick wheelchair seat cushion device, the lower end of the seat cushion frame is fixedly connected with a base, the base is provided with a cavity, the cavity is provided with a plurality of massage pieces, and the cavity passes through a sealing tube Connected to the extraction box.

Compared with the prior art, the advantages of the anti-sore wheelchair cushion device are:

1. The present invention can continuously extract the air at the seat cushion by setting the air extraction mechanism and the air holes arranged on the load-bearing pipe, so that the air at the seat cushion is kept in a circulating state, which can effectively reduce the dampness and heat of the user's buttocks. Thereby, it can prevent the user from sitting on the wheelchair for a long time and get sores.

2. In the present invention, by setting the elastic bellows and the cavity, when the air pumping mechanism continues to operate, it can drive the massage stick to move up and down continuously, squeeze and massage the user's buttocks, so as to relax the muscles and activate the collaterals, and further play the role of Prevention of acne.

Example 1

As shown in Figure 1-3, an anti-sick wheelchair seat cushion device includes a seat cushion frame 1 and an air extraction mechanism 2. There are grid-shaped load-bearing tubes 11 distributed vertically and horizontally in the seat cushion frame 1. The load-bearing tubes 11 and the seat cushion frame 1 The inner side walls are fixedly connected, the side walls of the load-bearing pipe 11 are provided with air holes 111, and the air holes 111 are evenly distributed in the middle of the seat cushion frame 1; The air extraction box 21 is arranged in a long strip shape, the air extraction box 21 can be fixedly installed on the lower part of the wheelchair seat cushion, and one end of the air extraction box 21 is open, and a piston plate 211 is slidably and sealedly connected in the air extraction box 21 .

A mounting bracket 212 is fixedly connected to the outer side 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 motor. There is a connecting rod 215, one end of the connecting rod 215 away from the turntable 214 is rotatably connected with the side wall of the piston plate 211, the side wall of the piston plate 211 away from the connecting rod 215 and the side wall of the air extraction box 21 together form a closed space 216, the bearing pipe 11 The one-way air intake pipe 3 is communicated with the air extraction box 21, the intake end of the one-way air intake pipe 3 is communicated with the load-bearing pipe 11, the exhaust end of the one-way air intake pipe 3 is communicated with the closed space 216, and the air extraction box 21 A one-way exhaust pipe 4 communicating with the outside is fixedly connected to the upper part.

When this embodiment is in use, the rotating shaft 213 drives the rotating disc 214 to rotate, the rotating disc 214 drives the connecting rod 215 to rotate, the connecting rod 215 deflects and drives the piston plate 211 to reciprocate in the air extraction box 21 , so that the volume of the closed space 216 changes continuously , when the volume of the closed space 216 becomes larger, under the action of air pressure, the external air enters the load-bearing pipe 11 from the air hole 111, and enters the air extraction box 21 from the one-way intake pipe 3. When the volume of the closed space 216 becomes smaller, Under the action of air pressure, the air in the closed space 216 is discharged from the one-way exhaust pipe 4 to the outside, and in this way, the air at the seat cushion can be continuously drawn away, and the air at the seat cushion can be kept in a circulating state, which can effectively slow down the The user's buttocks are hot and humid, thereby preventing the user from sitting on the wheelchair for a long time and suffering from sitting sores.

Example 2

As shown in FIGS. 4-8 , the difference between this embodiment and Embodiment 1 is that a base 5 is fixedly connected to the lower end of the cushion frame 1 , the edge of the base 5 is flush with the cushion frame 1 , and a cavity is provided in the base 5 51. A plurality of massage pieces 52 are arranged in the cavity 51. The upper end of the cavity 51 is provided with a plurality of sliding holes corresponding to the gaps of the grid-shaped load-bearing tubes 11. The massage pieces 52 are massage sticks 521, and the massage sticks 521 slide. It is sealed and connected in the sliding hole. The massage stick 521 is provided with an annular limit slot 522. The massage stick 521 is slidably and sealedly connected to the sliding hole through the annular limit slot 522, and the upper end of the massage stick 521 is a circular protrusion 523. It can improve the massage effect. The cavity 51 is communicated with the air extraction box 21 through the sealing pipe 6. Specifically, the air extraction box 21 is provided with an elastic bellows 217. The direction is free to expand and contract, one end of the elastic bellows 217 is fixedly connected with the side wall of the piston plate 211 away from the connecting rod 215, the other end of the elastic bellows 217 is fixedly connected with the inner side wall of the air extraction box 21, and the two ends of the sealing pipe 6 are The cavity 51 and the elastic bellows 217 communicate with each other.

In this embodiment, when the elastic bellows 217 is stretched, under the action of air pressure, the air in the cavity 51 will be inhaled, so that the massage stick 521 will move downward. The gas is filled into the cavity 51, so that the massage stick 521 is pushed out upward, and squeezes and massages the user's buttocks, which has the effect of relaxing the tendons and activating the collaterals, and further plays the role of preventing acne.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
