Background

The reagent kit of the saccharification glucometer with the function of automatically dripping the reagent comprises a liquid storage device, a piston, a needle seat, a liquid pipe, a sealing cover and a shell, the reagent is filled and assembled before leaving a factory, and the reagent kit has high requirements on the sealing property among all components due to the complex composition, so that the production process and the yield are challenged. During the actual production, storage and use, the following difficulties mainly exist:

1. the needle seat is connected with the liquid storage device by a luer interface, so that the long-term sealing performance cannot be ensured;

2. in order to prevent blockage caused by crystallization of residual reagent in a liquid tube, a polytetrafluoroethylene tube is adopted, but the polytetrafluoroethylene tube is very difficult to bond with a needle seat, so that reliable sealing cannot be ensured;

3. the internal situation of the kit is invisible after the assembly is finished, and if the leakage happens, a user cannot know the leakage, so that the test fails.

To this end, we propose an in vitro diagnostic device kit.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to FIGS. 1-2, an in vitro diagnostic device kit comprises

The kit support is formed by covering a bottom shell 1 and an upper shell 2, and the upper shell 2 is made of transparent material or is provided with a partially transparent observation window, so that the liquid reservoir 5 can be observed conveniently; the bottom shell 1 is provided with a plurality of containing shells 1.1, the side wall of the bottom shell 1 is provided with a plurality of through holes corresponding to the containing shells 1.1, a liquid storage device 5 conveniently passes through the through holes to move into the containing shells 1.1, the side wall of the containing shells 1.1 far away from the through holes is inserted with needle tubes 3, the needle tubes 3 are made of hard materials, and the needle tubes are replaced by the needle tubes made of hard materials instead of liquid tubes, so that the machinability is improved;
