Autonomous PICC functional exerciser

Abstract

The invention discloses an autonomous PICC functional exerciser, and belongs to the technical field of medical auxiliary instruments. The autonomous PICC functional exerciser comprises an arm sleeve which is of a double-layer structure, wherein an air chamber is formed between the double-layer structure; an inflation device which is communicated with the air chamber; a deflation valve which is arranged on the arm sleeve and communicated with the air chamber; and a controller which is connected with the inflation device and the deflation valve and can control a pressure threshold value and inflating and deflating time. The autonomous PICC function exerciser can also be used by a patient lacking autonomous exercise ability, and medical workers can set exercise time and pressure according to individualized requirements, so that exercise is more scientific and effective. According to the exerciser, the mode of segmental gradual autonomous inflation and deflation is adopted, blood is sequentially pressed into the forearm from the hand, then pressed into the upper arm and finally converged into the superior vena cava through the pressure of air in the air chamber, and the effects of promoting blood backflow of the upper limbs, reducing thrombosis and preventing PICC complications are achieved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an autonomous PICC function exerciser. Background technique [0002] Peripherally inserted central catheter (PICC) is an important infusion route in clinical practice, and has become the preferred infusion route for patients who need long-term repeated intravenous infusion, especially for patients treated with chemotherapeutic drugs (chemotherapy). However, since the PICC catheter is a foreign body in the body, it is easy to cause complications after catheterization, among which thrombosis is one of the common complications of PICC catheters. [0003] At present, the prevention method for thrombosis after PICC catheterization is mainly hand function exercise, that is, holding a power ball exercise. However, the grip balls currently used clinically are mainly simple and elastic spheres. The disadvantages of the existing grip balls are the lack of uniform stand...

AI Technical Summary

Problems solved by technology

However, the grip balls currently used clinically are mainly simple and elastic spheres. The disadvantages of the existing grip balls are the lack of uniform standards, and the softness and hardness are different. Too soft can not achieve the exercise effect and is easy to break. Reduced compliance

Moreover, the existing grip ball can only exercise the hands simply, it cannot play a good exercise effect on the wrist joints, elbow joints, and shoulder joints, and cannot promote the effective return of blood, and the effect of preventing complications is low.

For some patients who do not have the ability to actively exercise, such as patients who have been bedridden for a long time and have PICC implanted, the current effect of holding a grip ball to prevent thrombosis after PICC catheterization is poor

At present, there is no exercise device for patients who cannot make fists independently after PICC catheterization
