Technical Field

[0001] The utility model relates to the technical field of detection tubes, in particular to an automatic liquid injection device for a detection tube. Background Art

[0002] A test tube is generally a container used to test body fluids or excrement. A Puff-Puff tube is one of the test tools used to quickly check whether there is hidden blood in the stool. The detection method used by this type of test tube is similar to that of a pregnancy test stick. Test fluid often needs to be injected into the test tube for further testing.

[0003] The advantage of this type of test tube is that patients can use it at home, it is simple to operate, and only one tube is needed to clearly understand and recognize their physical condition. However, the tube body used for filling the test tube is also semi-automated or manually loaded and assembled, which has a low degree of automation and low production efficiency. In particular, some test tubes require a cap after filling to prevent spillage. Therefore, a device that can automatically fill the liquid and prevent spillage is needed. Utility Model Content

[0007] Furthermore, a second guide rail is provided on the outer shell, and a movable chuck for loading the plastic tube is slidably connected to the second guide rail.

[0008] Furthermore, the moving assembly includes a lead screw arranged in the moving column, the lead screw is threadedly connected to a moving sleeve provided on the moving frame, the bracket is provided with a first guide rail, and the moving column is slidably connected to the first guide rail.

[0009] Furthermore, a rack is provided in the movable frame, one end of the rack is fixedly connected to a clamping block, and a gear for engaging with the rack is provided in the movable frame.

[0010] Furthermore, a buckle is fixedly connected to the clamping block, a bottle stopper is installed in the buckle, a telescopic rod is provided above the buckle, and a push block for inserting into the buckle is fixedly connected to the free end of the telescopic rod.

[0011] Furthermore, a third guide rail is provided in the movable frame, and a liquid injection pipe is installed on the third guide rail.

[0012] Furthermore, a liquid infusion tube connected to the liquid injection tube is provided above the movable frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model can inject liquid into the detection tubes in sequence, and during the injection process, the detection tubes that have just been injected can be sealed to avoid spillage, and the sealing and injection components are controlled separately, and only one part of them needs to be manipulated for use when needed.

DETAILED DESCRIPTION

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3The present embodiment provides an automatic liquid filling device for a test tube, comprising an external shell 11, a bracket 12 being provided on the external shell 11, a movable column 13 being slidably connected along the length direction of the bracket 12, a movable frame 17 being slidably connected to the movable column 13, an injection tube 23 for injection and a push block 21 for sealing being provided on the movable frame 17, and a movable component 19 being provided on the movable frame 17 for driving the injection tube 23 and the push block 21 to move.
