Embodiment Construction

[0021] Such as figure 1 As shown, the test tube cap removal mechanism according to the present invention includes: claw 1, button 2, cover cavity 3, transition cavity 4, linear motor 5, motor screw 6, support sheet metal 7, upper gasket 8, claw Sealing plate 9, claw fixing plate 10, hook 11, transition plate 12, lower gasket 13, first compression spring 14, lead screw nut 15, second compression spring 16.

[0022] Wherein, the test tube capping mechanism has a supporting sheet metal 7, and the interior forms a rectangular accommodation space as a whole. A linear motor 5 is arranged at the bottom of the accommodating space, and the bottom end of the linear motor 5 is fixed on the lower bottom surface of the supporting sheet metal 7 with four fasteners for driving the motor lead screw 6 .

[0023] The upper end of the motor lead screw 6 has an upper gasket 8, and the lower gasket 13 is arranged at the bottom. Wherein the upper gasket 8 is a strip-shaped structure, and one end...

Abstract

The invention provides an uncapping mechanism of test tubes. The uncapping mechanism is used for removing caps of the test tubes and capping the test tubes and comprises a claw, buttons, a cover plate cavity, a transition cavity, a linear motor, a motor screw, a supporting metal plate, an upper gasket, a claw sealing plate, a claw fixing plate, a hook, a transition plate, a lower gasket, a first compression spring, a screw nut and a second compression spring. The uncapping mechanism of the test tubes is used for clamping the caps of the test tubes, and the caps of the test tubes can be clamped on the condition that external force exerted on the caps of the test tubes is reduced. In the process of removing the caps of the test tubes, the caps of the test tubes can simultaneously rise, rotate and cover the test tubes again. The uncapping mechanism is adaptable to the test tubes and the caps of the test tubes of different heights.

Description

technical field [0001] The invention relates to a test tube cap removing mechanism, which belongs to the field of medical instruments. Background technique [0002] At present, medical blood collection tubes are usually vacuum blood collection tubes, which realize the blood collection function through negative pressure. In the process of analyzing blood samples by clinical laboratory instruments, the following two methods are generally used: [0003] 1. Remove the test tube cap in advance, and use a disposable plastic needle for blood sample extraction; [0004] 2. Use hard needles such as steel needles to penetrate the test tube cap to realize the extraction of blood samples. [0005] In the second solution, the sampling needle needs to be used multiple times, and in order to avoid cross-contamination between samples, it is necessary to provide an additional cleaning mechanism for the sampling needle. Therefore, the first method is adopted, that is, the cap of the test t...
