Integrated cam horizontal displacement clamping mechanism for throat swab sampling system

Abstract

The invention discloses an integrated cam horizontal displacement clamping mechanism for a throat swab sampling system. The integrated cam horizontal displacement clamping mechanism comprises a shell,a steering engine, an equidistant spiral disc, a linear guide rail, two clamping jaws and two rolling pieces; the shell comprises a first cover, a cylinder and a second cover; two arc-shaped throughgrooves which are centrosymmetric to each other are formed in the equidistant spiral disc; one ends of the two clamping jaws are arranged on the linear guide rail in a sliding and sleeving mode; and the two rolling pieces are correspondingly arranged in the two arc-shaped through grooves, and one ends of the two rolling pieces are fixed to one ends of the two clamping jaws in a one-to-one correspondence mode. When the steering engine drives the equidistant spiral disc to rotate forwards or reversely, the two rolling pieces move in the two arc-shaped through grooves in the same direction or opposite directions at the same speed, and thus the two clamping jaws move in the opposite directions along the linear guide rail at the same speed so as to clamp or release objects. According to the Integrated cam horizontal displacement clamping mechanism, a throat swab is clamped and loosened by the clamping jaws, the reliability of the automatic process of the throat swab sampling system is guaranteed, the structure is simple and compact, the occupied space is small, and the control mode is simple.

Description

technical field [0001] The invention relates to the technical field of throat swab sampling, in particular to an integrated cam horizontal displacement gripping mechanism for a throat swab sampling system. Background technique [0002] Pharyngeal swab test, as one of the important ways to detect the new crown epidemic, can play an important role in the prevention and control of the epidemic in various countries. However, during the sampling process, the test personnel need to wear protective clothing and double-layer gloves, and after completing a sampling Gloves must be changed once, which not only increases the risk of infection for testing personnel, but also greatly affects sampling efficiency. At the same time, with the spread of the new crown epidemic, there is an urgent shortage of medical personnel in many countries and places. Under such circumstances, manual inspection will also occupy a large amount of human resources, which is not conducive to the control of the ...

[0002] Pharyngeal swab test, as one of the important ways to detect the new crown epidemic, can play an important role in the prevention and control of the epidemic in various countries. However, during the sampling process, the test personnel need to wear protective clothing and double-layer gloves, and after completing a sampling Gloves must be changed once, which not only increases the risk of infection for testing personnel, but also greatly affects sampling efficiency

At the same time, with the spread of the new crown epidemic, there is an urgent shortage of medical personnel in many countries and places. In this case, manual inspection will also occupy a large amount of human resources, which is not conducive to the control of the epidemic.
