Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal devices, in particular to an antigen sample centrifugal device. Background Art

[0002] A centrifuge is also called a centrifuge. A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. In the preparation of antigens, it is often necessary to centrifuge the antigen raw materials, so a centrifuge is needed.

[0003] At present, the existing centrifuge devices on the market need to insert the test tube containing the antigen into the slot of the rotating component in the centrifuge during use. The gap between the slot and the test tube is small, and it is inconvenient to take out the test tube after the centrifugation is completed. In the related art, a spring is arranged in the shell where the slot is located. After the centrifugation operation is completed, the test tube is automatically ejected by the rebound force of the spring. Although the test tube can be easily taken out, the operation steps are relatively complicated. In addition, the position of the test tube is not fixed during the centrifugation operation, which has certain limitations and is inconvenient for staff to use. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] When in use, place the test tube containing the antigen raw material into the centrifuge, turn on the centrifuge, and centrifuge the test tube.

[0030] In the related art, when placing the test tube, the normal centrifugation of the test tube is not affected by the cooperation of the spring's rebound force and the limit rod. After completion, the test tube is pushed out by the spring's rebound force. Although it is convenient to take out the test tube, during use, it is necessary to press the pin rod first, and then rotate the limit rod before the test tube can be placed. After placement, it is still necessary to push the limit rod to align the pin rod with the hole, and fix the position of the pin rod by the spring's rebound force. The test tube cannot be fixed quickly and conveniently, and has certain limitations.

[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an antigen sample centrifuge device. When the test tube needs to be fixed, it is only necessary to push the push plate 24 horizontally to leak the center of the shell 13 and place the test tube into the shell 13. Then, the push plate 24 is reset through the rebound force of the spring 27 to limit the test tube. Otherwise, the test tube is ejected, which is more convenient and quick, and improves the convenience of the device.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:
