Test tube fixing and rotating device

Abstract

The invention discloses a test tube fixing and rotating device. The test tube fixing and rotating device comprises a test tube rotating, guiding and positioning mechanism, a test tube fixing mechanism, a support spring and a pressing sheet, wherein the test tube rotating, guiding and positioning mechanism is provided with a positioning cap, and is used for positioning an opening of each test tube,and the test tube positioning mechanism is used for fixing the test tubes. The test tube fixing and rotating device has the beneficial effects that the test tubes can be fixed at the same time, one test tube can be positioned as needed, repeated taking and placing of the test tubes is not needed, and a sampling process of liquid samples is simplified.

Description

technical field [0001] The invention relates to a device for fixing and rotating a liquid sample test tube, in particular to a fixing and rotating device for collecting a cerebrospinal fluid sample test tube, which belongs to the field of medical equipment. Background technique [0002] Taking liquid samples is a common practice in the course of clinical treatment. For example, tests of cerebrospinal fluid, blood, urine, etc. all require taking liquid samples from the human body. [0003] Among them, taking samples of cerebrospinal fluid is a routine diagnosis and treatment operation in neurology. During the process, a lumbar puncture needle needs to be inserted into the subarachnoid space of the spinal canal, and the cerebrospinal fluid is exported through the needle tube, and the cerebrospinal fluid is allowed to flow into the test tube for collection. . [0004] However, in the process of collecting cerebrospinal fluid samples, due to the need to detect different indicat...

Problems solved by technology

[0004] However, in the process of collecting cerebrospinal fluid samples, due to the need to detect different indicators, it is often necessary to collect cerebrospinal fluid samples in multiple test tubes. In this process, there are operations such as repeated handling of test tubes, which is not only time-consuming and cumbersome, but also takes a long time to expose cerebrospinal fluid. , likely to cause the risk of nosocomial infection

[0005] Therefore, in order to solve the problems of repeatedly taking and placing test tubes in the cerebrospinal fluid samples, the operation time is long, and the risk of iatrogenic exposure infection is likely to be caused, a device for fixing and rotating test tubes was invented, which can fix multiple test tubes at the same time. And position one of the test tubes according to the needs, no need to repeatedly take and place the test tubes, simplifying the sampling process of liquid samples such as cerebrospinal fluid
