Embodiment 1

[0040]This embodiment provides a device for adding liquid, including a card pushing assembly 1 and a liquid adding assembly 2; the card pushing assembly 1 includes a positioning base plate 101 and a pushing mechanism, and the positioning base plate 101 is used to distribute and place several gold plates along the axial direction. Standard card 3, one gold standard card 3 can be placed at one time for detection, or multiple gold standard cards 3 can be placed at one time for detection operation, the pushing mechanism will automatically push the gold standard card 3 to move axially along the positioning substrate 101; 2 includes a liquid-feeding needle 201 arranged above the positioning substrate 101, one end of the liquid-feeding needle 201 is connected to the liquid inlet pipe 4, and the other end is used to add liquid to the gold standard card 3 moved to the right below, and the free end of the liquid inlet pipe 4 It is directly connected to the liquid storage tank; the pinch ...

Embodiment 2

[0042] Further improvement on the basis of Example 1, the liquid adding device also includes a cleaning assembly 5; the liquid adding assembly 2 also includes a mounting bracket 202, a moving mechanism is provided on the mounting bracket 202, and a liquid adding needle is detachably installed on the moving mechanism 201; when liquid needs to be added, the moving mechanism drives the liquid adding needle 201 to move directly above the gold standard card 3 for adding liquid; when cleaning is required, the moving mechanism drives the liquid adding needle 201 to move to the cleaning component 5 for cleaning operation.

Embodiment 3

[0044] Further improvement on the basis of Embodiment 2, the moving mechanism includes a guide rail 203, a guide rail slider 204, a screw nut assembly 205 and a motor 206; One side plate is arranged parallel to the positioning substrate 101, the other side plate is perpendicular to the positioning substrate 101, the guide rail 203 is arranged on the vertical side plate of the mounting bracket 202, and the axial direction of the guide rail 203 is perpendicular to the axial direction of the positioning substrate 101 ; The guide rail slider 204 is detachably provided with a liquid filling needle 201; the motor 206 drives the screw nut assembly 205 to rotate, and the screw nut assembly 204 converts the rotational motion into the linear movement of the guide rail slider 204, and the guide rail slider 204 drives the charging The liquid needle 201 moves along the guide rail 203 ; the cleaning assembly 5 is arranged at one axial end of the guide rail 203 . Two identical position senso...

Abstract

The invention discloses a liquid adding device. The liquid adding device comprises a card pushing assembly and a liquid adding assembly; the card pushing assembly comprises a positioning base plate and a pushing mechanism, and a plurality of gold sample cards are distributed on the positioning base plate in an axial direction; the pushing mechanism automatically pushes the gold sample cards to axially move along the positioning base plate; the liquid adding assembly comprises a liquid adding needle arranged above the positioning base plate; and one end of the liquid adding needle is connectedwith a liquid inlet pipe, and the other end is used for adding liquid to the gold sample card which is moved to the space just below the liquid adding needle. The invention provides the automatic liquid adding device which can realize rapid and accurate liquid adding as well as can realize isolation of an operator and a sample.

Description

technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a device for adding liquid. Background technique [0002] In the field of in vitro diagnostics, some existing routine feces tests are still performed manually. In the process of manual feces detection, manual sampling is often relied on, and liquid addition is performed for specific test items. The speed is slow and the operation is complicated; and Feces have special properties such as exposure and unpleasant smell, which greatly limit the clinical development and application of this project. Contents of the invention [0003] The technical problem to be solved by the present invention is: in the routine detection process of feces by manual operation, there are disadvantages of complex operation and discomfort to the operator's senses. The present invention provides a device for adding liquid to solve the above problems , in the process of automatic liquid addi...
