Description

An automatic transfusion chair for patients with sprained feet

technical field

The invention relates to the technical field of medical infusion equipment, in particular to an automatic infusion chair for patients with sprained feet.

Background technique

The infusion chair is a seat used for patient infusion, and the infusion chair is also called drip chair, which is mainly used in medical units to infuse patients.

In daily life and work, there are often diseases that cause damage to the feet such as sprained feet. After sprained feet are especially prone to swelling and pain, sometimes in order to speed up the recovery time of ankle swelling and pain, anti-inflammatory drugs will be used for infusion However, during the infusion process, patients with sprained feet generally need to lift their legs so that the feet are higher than their legs in order to keep their feet from congested blood.

However, when a sprained foot occurs on one foot, during the infusion process of the patient, since the other foot is intact, there is no need to use the hospital bed, which takes up a lot of space and is troublesome to use, so only one foot is needed to move the leg. Raised infusion chair.

In the prior art, none of the infusion chairs has the function of lifting legs, and the application number is "201711030842.1", a leg support frame for nursing beds, including a base, a fixed splint, a fixed pin, a support column, a locking knob, and a beam , leg slots, massage pads and telescopic straps, wherein the side of the base is provided with a fixed splint, the fixed splint includes an upper splint and a lower splint, the fixed pin is connected with the upper splint through threads, and a retractable splint is arranged above the base. The support column, the outer surface of the support column is provided with a locking knob, the top of the support column is fixed with a beam, the beam and the support column are perpendicular to each other, and the upper surface of the outer end of the beam is provided with a downward arc-shaped leg slot , a massage cushion is fixedly arranged on the inner surface of the leg slot, a telescopic strap is arranged above the leg slot, and a lock is provided at the other end of the telescopic strap, which still has the following obvious defects: although the The leg support is raised, but it is used on the side of the bed and cannot cooperate with the chair. In addition, it needs to use external force to adjust the leg lifting mechanism during use, which is very troublesome.

Contents of the invention

The purpose of the present invention is to provide an automatic infusion chair for patients with sprained feet, so as to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:
