Background technique

With the development and progress of society and the improvement of people's living standards, the demand for caregivers is increasing and the requirements are getting higher and higher. More and more migrant workers have entered the nursing industry. In hospitals, communities or families, many patients have received services provided by caregivers. Since the objects of caregiver services are the elderly, the weak, the sick and the disabled among the population - vulnerable groups, the seemingly simple care work of caregivers contains many human and technical factors.

In medical care, some patients have difficulty in moving due to poor physical condition, so their families usually let them sit in wheelchairs.

In the utility model, the two backrest support rods of the wheelchair backrest are rotatably connected to the wheelchair frame through connecting pieces, and the bottom ends of the backrest support rods are connected to the wheelchair frame through angle adjustment mechanisms, so that the angle between the backrest support rods and the wheelchair frame can be adjusted through the angle adjustment mechanisms to change the angle between the wheelchair backrest and the wheelchair frame, thereby adjusting the angle of the wheelchair backrest. This allows patients to choose a suitable angle to sit on the wheelchair, avoid sitting upright on the wheelchair for a long time, reduce the stress on the patient's buttocks and thighs, and avoid soreness and numbness. It is convenient to take a short rest on the wheelchair to meet the patient's use needs.

In this embodiment, the specific structure of the angle adjustment mechanism is: it includes an adjustment tube 7 installed on the wheelchair frame in the horizontal longitudinal direction (the direction of wheelchair travel), an adjustment rod 8 is slidably arranged in the adjustment tube, and the adjustment rod is hingedly connected to the seat back support rod at one end close to the seat back support rod; positioning holes 9 are respectively opened on the outer peripheral surfaces of the adjustment tube and the adjustment rod, wherein the adjustment tube has multiple positioning holes, and they are evenly spaced along the length direction of the adjustment tube; a positioning pin is provided in the positioning hole of the adjustment rod, and the positioning pin has a fixed end and a telescopic end. The fixed end of the positioning pin is installed in the positioning hole of the adjustment rod, and the telescopic end of the positioning pin is pressed to pass through the corresponding positioning hole on the adjustment tube to adjust the angle of the wheelchair backrest.

When in use, after the patient sits on the wheelchair, the patient's back rests on the backrest cushion, and the patient presses the telescopic end of the positioning pin by hand, and the adjusting rod moves axially in the adjusting tube, so that the telescopic end of the positioning pin passes through the corresponding positioning hole on the adjusting tube, thereby adjusting the wheelchair backrest angle; the chair backrest angle increases with the number of corresponding positioning holes on the adjusting tube through which the telescopic end of the positioning pin passes.

It should be further explained that, in addition to the above structure, the angle adjustment mechanism may also adopt other structures, for example: an adjustment tube is installed horizontally and longitudinally on the wheelchair bracket, an adjustment rod is slidably arranged in the adjustment tube, and one end of the adjustment rod is close to the seat back support rod and is hingedly connected to the seat back support rod; positioning holes are respectively opened on the outer circumference of the adjustment tube and the adjustment rod, wherein the adjustment tube has multiple positioning holes, and they are evenly spaced along the length direction of the adjustment tube. When the positioning holes on the adjustment tube and the adjustment rod are aligned, bolts are passed through the positioning holes and then locked with nuts.

After adjusting the wheelchair backrest angle, in order to reset the wheelchair backrest angle and facilitate medical staff or family members to push the wheelchair, in this embodiment, an internal thread is provided at the end of the adjustment tube 7 away from the wheelchair bracket, and a bolt is threadedly connected; a spring is provided in the adjustment tube, one end of the spring abuts against the bolt, and the other end of the spring abuts against the adjustment rod, so that the wheelchair backrest angle is reset by the spring rebound.

In this way, after the wheelchair backrest angle is adjusted, the spring is in a compressed state, pressing the telescopic end of the positioning pin, and the spring pushes the adjustment rod to slide in the adjustment tube in the opposite direction and pass through the corresponding positioning hole on the adjustment tube, thereby gradually resetting the wheelchair backrest angle.

In order to facilitate pressing the positioning pin and quickly adjust the wheelchair backrest angle, in this embodiment, a slide groove 10 is axially opened on the outer peripheral surface of the adjustment tube 7 to connect all the positioning holes of the adjustment tube, and a sleeve 11 is sleeved on the adjustment tube. The inner wall of the sleeve radially protrudes to form a convex strip that matches the slide groove.

The reset pin has a fixed end and a telescopic end. A reset spring is provided in the telescopic end of the reset pin. The fixed end of the reset pin is installed in the mounting hole, and the telescopic end of the reset pin abuts against the bottom of the slide groove.

In this way, when the sleeve moves axially on the adjusting tube, the telescopic end of the reset pin abuts against the telescopic end of the positioning pin, causing the telescopic end of the positioning pin to retract a part, and the adjusting rod is stressed to move axially in the adjusting tube, thereby quickly adjusting the wheelchair backrest angle.

Referring to FIG2 , when the wheelchair backrest angle is realized and the force on the patient's buttocks and thighs is reduced, the patient's thigh pain and numbness after sitting for a long time are further reduced. In this embodiment, a massage mechanism is also provided, specifically:

The above-mentioned seat cushion 2 includes a seat plate 21 and an elastic seat cushion 22 arranged on the upper surface of the seat plate. A mounting groove is opened on the lower surface of the seat plate, and a rotating shaft 23 and a motor 24 are rotatably installed in the mounting groove. The output shaft of the motor is connected with the rotating shaft key, and the input end of the motor is connected with the output end of the controller through a wire so as to control the start and stop of the motor through the controller. An arc-shaped protrusion 25 radially protrudes on the outer circumference of the rotating shaft. There are multiple arc-shaped protrusions and they are evenly spaced in the axial direction. Massage holes corresponding to the positions of the arc-shaped protrusions are opened on the upper surface of the seat plate, and a massage column 26 is slidably arranged in the massage hole. A massage spring is sleeved on the massage column, and the bottom end of the massage column abuts against the arc-shaped protrusion. The top end of the massage column extends out of the massage hole and is provided with a rubber top.

When in use, the motor is started by the controller, and the motor can be powered by a battery. The motor drives the rotating shaft and the arc-shaped protrusion on the rotating shaft to rotate axially. The arc-shaped protrusion has a lowest point and a highest point to promote the massage slide. The massage spring is compressed and the surface of the seat cushion bulges. When the massage column slides over the highest point of the arc-shaped protrusion, the massage spring rebounds and the massage column is reset. This process is repeated to massage the patient's thigh, thereby further reducing the problem of soreness and numbness in the patient's thigh after sitting for a long time.

Referring to Fig. 1, in order to facilitate the patient to get good support for the waist after adjusting the wheelchair backrest angle, in this embodiment, an airbag is provided on the backrest cushion, the airbag has an air inlet, a trachea connected to the airbag is installed at the air inlet of the airbag, and an air pump is connected to the air inlet of the trachea to inflate the airbag through the air pump.

In this way, by embedding an air bag corresponding to the patient's waist position in the back cushion, the patient's waist can be well supported when lying on the wheelchair to rest. The air bag is connected to the air pump through an air tube, and the inflation state of the air bag can be controlled as needed. It is easy to use and greatly improves the patient's rest comfort.

Referring to FIG1 , in order to facilitate good ventilation and heat dissipation of the patient's buttocks, in this embodiment, side guard plates 12 are vertically arranged on the left and right sides of the wheelchair frame, and a plurality of air holes 13 are evenly spaced on the surface of the side guard plates to facilitate ventilation and heat dissipation.

For the convenience of placing the patient's arms, armrests 14 are symmetrically arranged on the wheelchair support in the present embodiment, so that the arms can be placed. In this way, when the patient needs to rest, the arm can be placed on the armrests to relax the patient.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described by referring to the preferred embodiments of the utility model, those skilled in the art should understand that various changes can be made in form and details without departing from the spirit and scope of the utility model as defined in the appended claims.
