Description

A multifunctional wheelchair

technical field

The invention relates to a wheelchair device, in particular to a multifunctional wheelchair.

Background technique

Wheelchair is a commonly used medical transportation tool. It is commonly used in medical treatment for patients with limited mobility. Existing wheelchairs have diversified functions, but sometimes some patients with limited mobility need to move infusion, so that only a special person can hold the infusion bottle, or use it for The support bar supports the medicine bottle tied to the wheelchair. Hand-holding the infusion bottle will increase the workload of the medical staff, and it will be very tiring to hold the medicine bottle for a long time. In addition, the support bar tied to the wheelchair will be very unstable and prone to danger. At the same time, the continuous movement of the medicine bottle will affect the effect of infusion, and at the same time, during the infusion process, the infusion tube will often get entangled into the wheel of the wheelchair and cause danger due to being too long.

Contents of the invention

The purpose of the present invention is to provide a multi-functional wheelchair to solve the problem that the infusion tube is easily entangled into the wheel and cause danger when the wheelchair cannot meet the needs of walking infusion and walking infusion during use.

The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is:

A multifunctional wheelchair, comprising a wheelchair body, on which a speed-limiting device is arranged, and the speed-limiting device includes a centrifugal pulley, a spring, a centrifugal pin, and a large pulley, a small pulley and a driving pulley linked by a belt, wherein the large pulley and the small pulley are installed on the bracket of the wheelchair body, the driving wheel and the rear wheel of the wheelchair body are arranged on the same rotation axis, the centrifugal wheel and the small pulley are arranged on the same rotation axis, and the centrifugal pin is arranged in the radially distributed through groove on the centrifugal wheel. And it is connected with the spring whose force points to the rotation axis of the centrifugal wheel. The rotation of the rear wheel of the wheelchair body is driven by the driving wheel, the large pulley and the small pulley in turn to drive the centrifugal wheel to rotate, so that the centrifugal pin contacts the ground under the action of centrifugal force and produces friction to the limit. Faster effect, the wheelchair body support is also provided with an infusion bottle support mechanism, the infusion bottle support mechanism includes a support bar, a cross bar and a fixing bag, the support bar is fixed on the bracket of the wheelchair body, and the cross bar is vertically fixed on the On the support bar, the fixed bag is fixed on the cross bar and a zipper is installed on the fixed bag so as to open the fixed bag and put the infusion medicine bottle into it. Protective device, the protective device includes a plurality of protective rings installed on the wheelchair body bracket, the protective ring includes two semi-circular rings with one end connected by a rotating shaft and a connecting plate at the other end, the two semi-circular rings cooperate to form a In the protective ring, the connecting plate is pierced with fixed pins to limit the free rotation between the semicircular rings in the protective ring.

The beneficial effects of the present invention are: the present invention can fix the infusion bottle on the wheelchair through the support mechanism of the infusion bottle, which facilitates the infusion during walking and reduces the work intensity of the medical staff, and at the same time fixes the medicine bottle through the fixing bag to avoid the shaking of the medicine bottle , and the zipper set at the same time is convenient and quick to operate and fixed firmly.

The present invention is also provided with a protective ring, which can protect the infusion tube from being wound into the wheel, thus not only protecting the patient but also avoiding personnel fatigue caused by observing the infusion tube at any time.

At the same time, a speed-limiting device is set, which can control the speed of the wheelchair and avoid the shaking of the infusion bottle caused by the excessive speed of the wheelchair, thereby ensuring that the liquid in the infusion bottle is in a static state, which can provide a better infusion environment.
