Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, if there are descriptions involving "first", "second" and so on in ...

Abstract

The invention provides a liquid flow driving device for a POCT hematology analyzer and an impedance detection cell. The driving device comprises a pressure source; the impedance detection cell comprises a front cell and a rear cell which are communicated through a micropore, and a detection electrode used for cooperatively carrying out impedance detection; the pressure source is used for applying pressure to the front cell, so that liquid in the front cell flows to the rear cell through the micropore. By applying pressure to the front cell, liquid in the front cell flows to the rear cell through the micropore, so that an additional negative pressure generation device is not needed; and the pressure source can reuse a pipettor in the POCT hematology analyzer, so that the product assembly structure can be simplified, and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of blood sample analysis, in particular to a POCT blood cell analyzer and a liquid flow driving device for an impedance detection cell. Background technique [0002] Blood cell analyzer, also known as blood cell analyzer, blood cell analyzer, blood cell counter, etc., is one of the most widely used instruments in hospital clinical testing. [0003] Most of the components in the traditional blood cell analyzer belong to the cleaning system, because before the next blood sample test, it is necessary to ensure that the traces of the previous blood sample are cleaned. The entire cleaning system not only has a complex structure and many parts, but also requires a large amount of reagents and takes a long time during the cleaning process. [0004] Compared with the traditional blood cell analyzer, the POCT blood cell analyzer has greatly simplified the instrument components. The POCT blood cell analyzer can compl...
