Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1 to 3, the wheelchair provided by the present invention includes a seat 1, a backrest 2, an upper armrest 3 and an adjusting mechanism, wherein the backrest 2 is disposed on the seat 1, the adjusting mechanism is disposed in the backrest 2, the upper armrest 3 is disposed on the adjusting mechanism, the upper armrest 3 has a first position located on a side of the backrest 2 away from the seat 1 and used for pushing and pulling the wheelchair, and a second position used for supporting an armpit of a user and lifting the user, and the adjusting mechanism drives the upper armrest 3 to freely switch between the first position and the second position.

When the upper armrest 3 is switched to the first position, the accompanying person can move the wheelchair through the upper armrest 3 at the rear of the wheelchair, and when the patient is alone and needs to take off the clothes of the lower body to go to the toilet or change the clothes, the patient can switch the upper armrest 3 to the second position, the armpit of the patient is supported by the upper armrest 3, and the patient lifts the body off the chair 1 by the force of the upper body and the lifting force of the upper armrest 3, so that the patient can directly change or put on or take off the clothes, and the operation can be realized by only one person without the accompanying person. The operation that just can accomplish the change of clothes or wear to take off under accompanying person's help when the effectual patient that has overcome among the prior art uses the wheelchair, and use is simple and convenient.

Preferably, the rotation angle of the upper handrail 3 is 160 ° to 200 °, preferably 180 °, and the lifting height of the upper handrail 3 is 5cm to 10cm, preferably 8 cm.

The adjusting mechanism comprises a shell 8, a hydraulic cylinder 4, a piston 5 and a lead screw 6, wherein the piston 5 is movably arranged in the hydraulic cylinder 4, the lead screw 6 is arranged on the piston 5, a lead screw nut is arranged on the shell 8, the lead screw nut is in threaded fit with the lead screw 6, the upper handrail 3 is arranged on the piston 5, and the upper handrail 3 can move up and down and rotate along with the piston 5. When the hydraulic cylinder 4 is filled with high-pressure hydraulic oil, the hydraulic oil drives the piston 5 to move, and because the piston 5 is provided with the lead screw, the piston 5 is forced to rotate under the matching of the lead screw nut and the lead screw 6, namely the upper handrail 3 at the moment can be simultaneously lifted and rotated under the driving of the piston 5, wherein the matching thread space between the lead screw nut and the lead screw 6 can ensure that the upper handrail 3 just rotates to a corresponding angle (such as 180 degrees) when the piston 5 moves to a set height (such as 8 cm).

Preferably, the adjusting mechanism further comprises a connecting rod, one end of the connecting rod is arranged on the piston 5, the upper handrail 3 is arranged on the other end of the connecting rod, and the movement of the piston 5 is transmitted to the upper handrail 3 through the connecting rod.

Optionally, a pressure inlet and a pressure outlet are arranged on the hydraulic cylinder 4, a patient can control the opening and closing of the pressure inlet according to a remote controller on the hand, when the pressure inlet is opened, the piston 5 starts to move to drive the second position of the upper armrest 3 to move, when the pressure inlet is closed, the piston 5 descends under the self gravity, meanwhile, pressure oil in the hydraulic cylinder 4 is discharged through the pressure outlet, and the upper armrest 3 resets to the first position along with the descending of the piston 5 and the action of the screw 6.

The wheelchair still includes slewing mechanism, back 2 pass through slewing mechanism set up in on the seat 1, the wheelchair has the state of lying flat and position of sitting state, works as when the wheelchair is in the state of lying flat, back 2 with seat 1 has first contained angle, works as when the wheelchair is in the position of sitting state, back 2 with seat 1 has the second contained angle, first contained angle is greater than the second contained angle. Preferably, the angle of the first included angle is 180 °, and the patient can lie down.

Go up handrail 3 and include telescopic machanism, telescopic machanism's fixed end set up in adjustment mechanism is last, telescopic machanism's free end can be kept away from or be close to the fixed end, and the wheelchair is in when lying flat the state, free end and ground butt. The upper arm rest 3 is extended so that the end of the upper arm rest 3 can be supported on the ground, and at this time, a supporting force can be generated to the end of the backrest 2 far from the seat 1, thereby ensuring the reliability of the backrest 2.

The seat 1 is provided with a defecation hole 7, and a toilet accommodating space is formed below the defecation hole 7. When a patient needs to defecate, the patient can drive the wheelchair to reach the toilet, the toilet in the toilet enters the toilet accommodating space by adjusting the position of the wheelchair, then the clothes of the lower half of the body are taken off under the lifting action of the upper handrail 3 at the second position to defecate, and the clothes of the lower half of the body are discharged into the toilet at the lower part through the discharge hole 7, after the defecating is finished, the clothes of the lower half of the body can be independently worn, so that the defecating process can be finished when the patient alone. As shown in fig. 2, the toilet can enter the wheelchair from the front of the wheelchair and reach below the defecation hole 7.

The seat 1 is further provided with a baffle plate 9, and the baffle plate 9 can open or shield the defecation hole 7. The flat shaping of the seat 1 is ensured by the flap 9.

When the wheelchair is an electric wheelchair, the wheelchair further comprises a storage battery, and the storage battery is arranged on one side of the closestool. The storage battery and the closestool are prevented from generating structural interference.

The wheelchair further comprises a shank massage mechanism 10 and a pedal, wherein the pedal is arranged in front of the seat 1, and the shank massage mechanism 10 is arranged between the pedal and the seat 1. The shank massage mechanism 10 is used for massaging the shank of the patient, so that the rehabilitation speed of the patient is increased.

The calf massage mechanism 10 includes an air bag. The air bag is inflated and deflated to extrude and relax the shank part, so that the massage effect is achieved.

When the patient need transfer to other positions (like on the bed) from the wheelchair, generally need the attendant to remove the mode of adding or hugging the patient among the prior art, and in this application the wheelchair still includes tilting mechanism, tilting mechanism set up in the below of seat 1, just tilting mechanism can adjust the contained angle of seat 1 and horizontal plane. If the patient needs to be transferred to the bed, the wheelchair can be switched to a lying state and placed on one side of the bed in parallel, then the elbow support and the support frame at the corresponding positions are detached, and then the seat 1 is inclined by the aid of the overturning mechanism, so that the patient can roll to the bed along with the inclination of the seat 1.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
