A test tube holder used for medical examination

Abstract

A test tube holder used for medical examination is disclosed. The test tube holder includes two holding bars, a connecting bar shaft and two arc-shaped clamping plates. Two vertical supporting bars are provided with a rotation gear. The inner side of the rotation gear is connected to the external walls of the vertical supporting bars through a ratchet mechanism. The ratchet mechanism includes an outer ring sleeve the internal side wall of which is provided with a plurality of wedgy ratchet slots, and an inner ring sleeve the external side wall of which is provided with a plurality of ratchets.A side surface, close to a fixed plate, of a pushing plate is provided with a plurality of limiting guide bars penetrating the fixed plate and slidingly connected to the fixed plate. One end, of eachof the plurality of limiting guide bars, close to the rotation gear penetrates into one of a plurality limiting through slots in the end surface of the inner ring sleeve. Two sides of the rotation gear are provided with arc-shaped racks meshed with the rotation gear, and one end of each of the arc-shaped racks is fixedly connected to the middle of the corresponding holding bar. The test tube holder is simple in structure, convenient to use, labor-saving, firm to hold, capable of protecting a test tube from dropping and high in practicability.

Description

technical field [0001] The invention relates to a medical device, in particular to a test tube holder for medical inspection. Background technique [0002] In the process of medical treatment, a large number of medical reagents are often tested, so test tubes are required for device testing. In the process of testing, test tubes are held by test tube holders to avoid cleanliness and reagents from contaminating the human body. General test tubes Clamping is carried out by the inspector pressing the splint. In this way, during the inspection process, the inspector needs to press and clamp all the time, and people's attention may be distracted, so that the palm of the hand will be loose during the process of clamping the test tube, which will cause The clamping is not tight enough to cause the test tube to fall, and then it needs to be re-inspected, which is troublesome. Contents of the invention [0003] The object of the present invention is to provide a test tube holder f...
