Cap removal device of sampling swab

Abstract

The invention relates to the field of medical apparatuses, aiming at providing a cap removal device of a sampling swab. The device comprises a test tube clamping mechanism and a cap removal mechanism, wherein the cap removal mechanism comprises a cap removal claw and a balancing weight; both the cap removal claw and the balancing weight are arranged on a linear guide way pair; the balancing weight is arranged above the cap removal claw; the linear guide way pair is arranged on a supporting plate; both the linear guide way pair and the supporting plate are distributed in a vertical Z axle direction; a transverse extension part is arranged at the bottom of the cap removal claw, and a cap removal groove is formed in the extension part; a stopping part, which transversely protrude, is arranged on the balancing weight; and the cap removal claw is connected to the supporting plate by virtue of a driving mechanism and is capable of moving on the linear guide way pair. The cap removal device disclosed by the invention can automatically implement cap removal, capping and discarding operations, and can, in the coordination with other matched devices, conduct sample separation and uniform blending treatment on the sampling swab, so as to achieve re-capping and automatic discarding. The cap removal device, while relieving cross pollution in a process, can liberate workforce through automatic operations, so that a pre-treatment operation on a sample is standardized.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cap-removing device for a sampling swab. Background technique [0002] At present, when sampling vaginal secretions, many operators only use a special long cotton swab to directly dip it, then put it into a glass test tube, and transfer it without any cover until it is sent to the laboratory for testing. Uncertainties in the hospital environment and transport movements can easily lead to contamination of specimens. This leads to inaccurate results, which cannot truly reflect the patient's condition and cause misdiagnosis. During the test, the examiner will add reagents to the test tube and then stir it so that the secretion on the cotton swab head can fall off. However, in the whole process, due to the inaccuracy of the amount of reagent added and the difference of stirring level, the completion degree of secretion shedding and the level of dissolved concentration will be det...
