Description

A wheelchair toilet

technical field

The device relates to the field of medical care equipment, in particular to a toilet suitable for wheelchairs.

Background technique

In daily life, for people who suffer from lower limb paraplegia and mobility impairment due to illness or injury, wheelchairs are generally used as the main means of mobility for patients, and patients spend a large part of their time in wheelchairs. There are many styles of common wheelchairs, and the structures are not the same, but they are basically composed of cushions, chair frames and universal wheels. Although such a wheelchair can meet the needs of the patient's daily activities, it will be very inconvenient when the patient defecates. Although there are some wheelchairs with a toilet seat on the market, these wheelchairs are slotted in front of the seat cushion. When using it, the patient needs to move his legs away first, support his body with his hands, and the nursing staff will pull out the defecation door on the cushion, and then help the patient take off his pants before defecating, and the user cannot complete the operation independently . The defecation door is the rectangular cutting strip left after slotting in the middle of the seat cushion.

Contents of the invention

In order to overcome the deficiency that the patient cannot independently complete defecation and defecation in the prior art, the utility model provides a novel wheelchair toilet. The toilet seat cushion of the wheelchair has a defecation door, which can be opened or closed following the movement of the back of the chair. , so that patients can independently complete the operation through simple actions such as lying down and sitting up.

The technical solution adopted by the utility model to solve the technical problems is: through the connecting rod slider mechanism formed by the wheelchair backrest 1 and the defecation door 5, etc., the function of self-help toilet entry is realized. The structure includes: a wheelchair backrest 1, a long connecting rod 2, a short connecting rod 3, a slider 4, a defecation door 5, a toilet container 6, a seat cushion 7, a spring latch 10, and a positioning pin 11. The wheelchair backrest 1 can rotate backward around the hinge connected with the vehicle frame, and one end of the long connecting rod 2 is hinged with the backrest 1, and the other end is hinged with the slider 4; the slider 4 is one under each side of the wheelchair cushion 7, and is mounted on the seat cushion. 7. The linear guide rails on the left and right sides below form a moving pair. One end of the short connecting rod 3 is also hinged with the slide block 4, and the other end is hinged with the defecation door 5 by the spring latch 10; the defecation door 5 is installed on the U-shaped cushion 7 (a rectangular opening of 20cm * 40cm is opened in the middle of the cushion 7 Groove and be U-shaped, form cooperation with the defecation door) on the guide rails on both sides inside. The closet pan 6 is placed below the seat cushion 7 and can be drawn out freely. When the backrest 1 is tilted backward, the long connecting rod 2 is driven, and the sliding block 4 is pulled to translate backward, and the sliding block 4 drives the defecation door 5 to move backward through the short connecting rod 3 .

The guide rail of the defecation door 5 has a certain angle with the plane of the seat cushion 7, so that the defecation door 5 slides obliquely along the guide rail, so that the defecation door 5 can be separated from the buttocks when moving backward and downward, reducing friction, and the defecation door 5 can be opened easily. The function of the spring latch 10 is to realize the connection and disengagement of the defecation door 5 and the short connecting rod 3. When the short connecting rod 3 was separated from the defecation door 5, after the backrest 1 fell down, the defecation door 5 would not be driven to open. The wheelchair can be used as a bed.

Both sides of the wheelchair backrest 1 are connected with the vehicle frame through two sleeves 9 below the wheelchair armrests. Extension springs 8 are housed in the sleeves 9. With the help of the springs 8, the normal vertical position of the wheelchair backrest 1 can be easily restored. In addition, the sleeve 9 is provided with positioning holes at a certain interval, through which the positioning pins 11 can be used to position the backrest 1 at several certain angle positions.

In the utility model, when the user is lying down, the backrest 1 is turned backwards, and the sliding block 4 is driven to open the defecation door 5. At the same time, the user can easily take off the trousers when lying down; With the assistance, the backrest 1 can be easily pulled up, and the defecation door 5 also returns to the original position thereupon.

The beneficial effects of the utility model are: due to the adoption of the connecting rod slider mechanism, the natural movement of the disabled person to lie down and take off his trousers is used to automatically open the defecation door, which can conveniently allow the disabled person to clean the defecation door smoothly without being looked after. The problem of urinating and defecating on the wheelchair is solved, and the shortcoming that the prior art cannot enable the disabled to solve the problem of urinating and defecating by themselves, that is, the disabled can only defecate and defecate on the wheelchair with the help of the nursing staff.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Detailed ways

The lower end of the wheelchair backrest 1 is hinged with the vehicle frame and can rotate backwards. The cross-section of the connecting rod is a circle with a diameter of 0.5 cm, one left and one symmetrical, the length of the long connecting rod 2 is: 55 cm, one end of it is 47 cm from the lower end of the backrest 1 through a bolt hinge, and the other end is hinged with the slider 4; 4. Each one under the left and right sides of the wheelchair cushion 7 (45cm*45cm), respectively forms a mobile pair with the linear guide rails fixed on the left and right sides below the cushion. The length of the short connecting rod 3 is: 45cm, and one end of it is also hinged with the slide block 4, and the other end is hinged with the lower side behind the defecation door 5, and the hinged mode at this place is as follows: 2 models are respectively fixed on the left and right sides of the rear, lower side of the defecation door 5 Be the spring latch 10 of 406, make short connecting rod 3 and defecation door 5 form hinge connection by spring latch 10, eject latch 10 and can make short connecting rod 3 and defecation door 5 disengage; On the guide rail on the side (a 20cm×40cm rectangular opening groove is opened in the middle of the seat cushion 7 to form a U shape, which is matched with the defecation door), the guide rail adopts a 36mm wide three-section steel ball slide rail, and one side uses 3 bolts and the seat cushion 7 is fixed, and the other side is fixed with 3 bolts and defecation door 5. The guide rail and the seat cushion 7 have a certain angle of about 15 degrees, so that the defecation door 5 slides obliquely along the guide rail, so that the defecation door 5 can quickly break away from the buttocks when moving backwards and downwards, reducing friction, and the defecation door 5 can be easily opened . A closet pan 6 is placed under the seat cushion 7 facing the defecation door 5, which can be drawn out freely.

Both sides of the wheelchair backrest 1 are connected with the vehicle frame through two sleeves 9 below the wheelchair armrests. Extension springs 8 are housed in the sleeves 9. With the help of the springs 8, the normal vertical position of the wheelchair backrest 1 can be easily restored. In addition, the sleeve 9 is provided with positioning holes at a certain interval, through which the positioning pins 11 can be used to position the backrest 1 at several certain angle positions.

When in use, as long as you lie down, when the backrest 1 tilts backward, it will drive the long connecting rod 2 to pull the slider 4 to move backward, and the slider 4 will drive the defecation door 4 to move backward through the short connecting rod 3. In the down state, you can easily take off your pants, because you can't take them off while sitting. When the spring latch 10 of the defecation door disengages from the short connecting rod 3, the backrest 1 can be made to lie down and the defecation door 5 is not opened, and now the wheelchair can be used as a bed again.
