Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically refers to a specimen storage device used in basic medicine. Background Art

[0002] In basic medical research and clinical testing, long-term storage of biological specimens requires strict control of temperature, humidity and cleanliness to avoid sample deterioration or cross contamination. However, existing specimen storage devices have the following technical defects:

[0003] (1) The specimen relies on rigid buckles or elastic clamps, lacking a buffer protection mechanism. When the equipment moves or vibrates, it is easy for the test tube to collide with the storage chamber, posing a risk of damage.

[0004] (2) Multiple test tubes are stored in the same space. When taking a single specimen, the entire cavity needs to be opened and closed, which increases the risk of cold loss and external contaminants. In addition, there is a lack of physical isolation between the test tubes, which can easily lead to label confusion or sample cross-contamination. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art and provides a specimen storage device for basic medicine. The linear movement of the piston assembly triggers the movement of gas in the placement tube. The state locking is completed by the self-locking assembly to complete the inflation and deflation control of the air bag, thereby achieving the clamping of the specimen test tube. At the same time, the reciprocating flow of gas in the pipeline provides power for the transmission assembly, converts linear kinetic energy into rotational power, and realizes the control of the capping assembly. After the test tube specimen is placed, the top end of the placement tube is sealed.

[0006] The technical solution adopted by the utility model is as follows: This solution provides a specimen storage device for basic medicine, including a box body and a refrigerator.

A reset spring is fixedly provided on the side wall of the longitudinal rod of the L-shaped push plate. The reset spring The other end of the spring is fixedly connected to the box body, and a placement tube is fixedly provided on the upper wall of the cross bar of the L-shaped push plate to directly carry and fix the specimen tube. A piston assembly is slidably provided on the inner wall of the placement tube to fix and release the specimen tube. A self-locking assembly that is in active contact with the piston assembly is provided at the lower part of the inner wall of the placement tube to lock and unlock the specimen tube. An airbag is fixedly provided on the upper wall of the inner wall of the placement tube to provide clamping force.

[0008] Furthermore, the self-locking assembly includes a fixed rod, a locking cone plate and an unlocking cone plate. The bottom end of the fixed rod is fixedly provided on the bottom wall of the placement tube. A baffle is fixedly provided on the circumferential wall of the fixed rod to support the self-locking cone plate and the unlocking cone plate. The locking cone plate is fixedly provided on the top of the fixed rod to lock the test tube. The unlocking cone plate is slidably sleeved on the fixed rod.

After passing the locking cone plate, the self-locking cone rod is reset and forms a rigid engagement with the bottom wall of the locking cone plate to achieve locking. After passing the unlocking cone plate, it is unlocked again under the action of the inclined surface. At the same time, the piston cap moves downward, compressing the gas at the bottom of the placement tube, forcing the air flow to be injected into the air bag through the pipeline to expand it, thereby clamping the specimen test tube and using the elastic deformation of the air bag to absorb multi-directional vibration energy to avoid rigid collision between the specimen test tube and the inner wall of the placement tube.

[0013] (2) When the specimen tube is stored, the air flows into the airbag, driving the impeller to rotate, driving the coaxially fixed transmission gear to mesh with the rack, thereby driving the cover to rotate, so that the cover seals the placed tube;

[0014] (3) This device is equipped with a separate specimen storage chamber, and each blood specimen tube is sealed and placed independently to avoid mixing of specimens and exposure of the entire specimen storage chamber when taking out the specimens. BRIEF DESCRIPTION OF THE DRAWINGS
