Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dripping devices, in particular to a CD4 detection reagent dripping device. Background Art
[0002] CD4 is a very important immune cell in the human body. It can control viral replication early and prevent the progression of immune damage. In addition, when a patient is infected with HIV, the CD4 cell count will decrease, indicating that the human immune system has been severely damaged. When testing CD4, it is often necessary to use a dropper to draw and then test. Existing droppers usually use a balloon to press, creating negative pressure in the extraction tube to extract the CD4 test fluid. However, if the balloon is loosened, the CD4 test fluid is easily dripped by gravity, causing environmental pollution. To this end, we propose a CD4 test reagent dripping device. Utility Model Content

The top of the dripping tube is connected to the connecting cavity, the top of the connecting cavity is connected to the vertical tube, the other end of the vertical tube is connected to the balloon, the top of the balloon is installed, the one-way valve B is installed, the bottom of the dripping tube is threadedly connected to the dripping head, and the tube wall of the dripping head is installed with the one-way valve A.
[0005] By adopting the above technical solution, when the CD4 detection reagent is dripped, since a dripping mechanism is installed on the wall of the dripping tube, the dripping mechanism is composed of a vertical tube, a balloon, a one-way valve A, a dripping head, a connecting chamber and a one-way valve B. Since the top of the balloon is connected and connected with a one-way valve B, after the personnel opens the one-way valve B, the personnel presses the balloon to compress it. After the personnel closes the one-way valve B, the personnel opens the valve tube A, inserts the dripping head into the CD4 detection reagent, and releases the balloon to allow the reagent to enter the vertical tube. After the personnel closes the one-way valve A, dripping of the detection reagent is avoided. When dripping, the personnel opens the one-way valve A and presses the balloon to discharge the detection reagent from the vertical tube.
[0006] Specifically, a protection mechanism is further included, and the outer wall of the connecting cavity is connected to the protection mechanism.
[0007] By adopting the above technical solution, the drip tube can be protected by the protection mechanism.
[0008] Specifically, the protective mechanism is composed of a sleeve, a thread groove A and a thread groove B. The thread groove B is opened on the outer wall of the connecting cavity, and the thread groove A is opened on the inner wall of the sleeve. The thread groove A is threadedly connected to the thread groove B.
[0009] By adopting the above technical solution, when the drip tube is protected, since the outer wall of the connecting cavity is connected to a protective mechanism, the protective mechanism is composed of a sleeve, a thread groove A and a thread groove B. Since the thread groove B is provided on the outer wall of the connecting cavity and the thread groove A is provided on the inner wall of the sleeve, after the thread groove A is threadedly connected with the thread groove B, the drip tube is located in the sleeve, thereby realizing protection of the drip tube.
[0010] Specifically, a cross bar is installed on the wall of the vertical pipe.

Since the top of the balloon 202 is connected and connected with a one-way valve B206, after the personnel opens the one-way valve B206, the personnel presses the balloon 202 to compress it. After the personnel closes the one-way valve B206, the personnel opens the valve tube A, inserts the dripping head 204 into the CD4 detection reagent, and releases the balloon 202 to allow the reagent to enter the vertical tube 201. After the personnel closes the one-way valve A203, the detection reagent is prevented from dripping. When dripping, the personnel opens the one-way valve A203 and presses the balloon 202 to discharge the detection reagent from the vertical tube 201.
[0025] like Figure 1 As shown, a protection mechanism 4 is also included, and the outer wall of the connecting cavity 205 is connected to the protection mechanism 4.
[0026] When in use, the drip tube 1 can be protected by the protection mechanism 4 .
[0027] like Figure 1 and Figure 2 As shown, the protective mechanism 4 is composed of a sleeve 401, a thread groove A402 and a thread groove B403.
