Device for detecting and extracting effusion pressure of old people

Abstract

The invention discloses an old-age effusion pressure detection and extraction device, which comprises two groups of arc-shaped frames, three groups of connecting rods are fixedly connected between the two groups of arc-shaped frames, the three groups of connecting rods are uniformly distributed around the arc-shaped frames, the tops of the two groups of arc-shaped frames are fixedly connected with connecting cylinders, and a mounting assembly is matched between the two groups of connecting cylinders. Two sliding assemblies are connected to the mounting assembly in a sliding mode, and an extraction assembly used for extracting hydrops and a detection mechanism used for detecting pressure are arranged on the two sliding assemblies correspondingly. The detection mechanism is arranged to detect the pressure change in the knee joint effusion cavity of the old people, so that medical staff can conveniently judge the effusion amount, the situation that joint fluid is excessively extracted, and consequently joint lubrication of the old people is insufficient is avoided, and practicability is high; the sliding assembly and the mounting assembly are arranged to fix the position of the needle head in a matched mode, the situation that the sharp part of the needle head hurts the body of old people due to misoperation of medical staff is prevented, and safety is high.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an elderly effusion pressure detection and extraction device. Background technique [0002] For middle-aged and elderly people, due to age, there will be more bone loss in the body, and degenerative changes will occur in the joints, which will easily produce joint effusion, causing joint pain and discomfort. Joint fluid is used to nourish articular cartilage, lubricate joints, and reduce friction during joint activities. Joint fluid is secreted by the synovium. During joint activities, joint fluid is continuously circulated and renewed. Joint effusion. [0003] If the joint effusion is not treated in time, it can lead to joint congestion, swelling, and pain in the affected area, and the affected joints will have limited function and difficulty in squatting. Currently, the treatment of joint effusion in the elderly is usually direct use The needle is inserted into the effusion ...

Problems solved by technology

[0003] If the joint effusion is not treated in time, it can lead to joint congestion, swelling, and pain in the affected area, and the affected joints will have limited function and difficulty in squatting. Currently, the treatment of joint effusion in the elderly is usually direct use The needle is inserted into the effusion cavity to suck out the effusion. Although this treatment method can solve the problem of joint effusion, due to the existence of human skin, medical staff cannot judge the amount of fluid in the effusion cavity, and the human body needs a small amount of joint fluid. It is used to reduce friction during joint activities. Excessive extraction of joint fluid will easily increase joint wear and tear, which is not conducive to the health of the elderly. When extracting joint fluid, only a simple medical needle is used. Because the end of the needle body is sharp, improper operation is easy to cause damage to the elderly. bodily harm
