Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to a sample collection and detection device and a sample collector and a sample detector thereof. The sample collector is provided with a liquid storage container and a sampling bar. A sealing baffle and an elastic rebound element are arranged at the outlet end of a liquid storage cavity. The sampling bar can abut against the inner wall of the liquid storage container in a sealed mode to form an injection structure. The sample collection and detection device stably pressurizes the liquid storage cavity in an injection type pressurizing mode, and a current stabilizing component is additionally arranged between the outlet of the liquid storage cavity and a detection mechanism. Atmospheric pressure and liquid tension in a reaction cavity in the sampling process are overcome by means of stable extrusion thrust and capillary absorption force of the current stabilizing component, it is guaranteed that sample solution output is stable, testing results are accurate, the operation process is simple, convenient and reliable, and the sample collection and detection device can be used conveniently by users.

Description

technical field [0001] The invention relates to the field of sample detection, in particular to a sample collection detector and the sample collector and sample detector. Background technique [0002] In the field of clinical or scientific research, it is often necessary to collect and test samples. Therefore, sample collection and testing instruments are widely used, such as the current household stool test instruments are more and more widely used. However, most household stool analyzers do not control the reaction solution well during use, and there is a problem that the sample solution is not loaded or the test paper is damaged by too much liquid (ie, sample flushing). The reason why the detection instrument does not load the sample is that the gravity of the sample solution itself cannot overcome the atmospheric negative pressure and liquid tension generated during the sample loading process in the reaction chamber when most household stool test instruments are sampled,...
