Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a pollution-proof raw plasma sample test tube cover opening machine. Background Art

[0002] In my country, the raw materials for the production of biological products companies come from raw plasma collected by plasma stations distributed throughout the country. In order to ensure the safety and accuracy of raw plasma samples used for infectious disease testing, the plasma station uses a closed specimen tube in the plasma bag used to collect plasma from donors. This design ensures that the plasma specimen tube will not be taken by mistake, thereby ensuring the accuracy and reliability of the specimen test results. There is a huge amount of plasma loaded in this closed test tube for statutory blood-borne infectious disease testing. Every day, hundreds of thousands of test tubes across the country need to be uncapped before the experiment. At present, this closed test tube is basically uncapped manually. Manual operation requires both hands to open the cap, one hand holding it tightly and the other hand prying it open, which is time-consuming and laborious. For manual operation, it is difficult to open the cap. After the cap is opened, the carrier strips are inserted one by one, and the repetitive actions are many and cumbersome. In this process, plasma will splash out, and there is a possibility of plasma contamination. In addition, due to the large number of test tubes, the manual workload increases accordingly. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides an anti-pollution raw plasma sample test tube capping machine, which is equipped with an isolation pusher and an isolation membrane, and can mechanically push and open the caps of closed test tubes, so that each test tube can be opened independently to avoid cross contamination between adjacent test tubes, and more test tubes can be opened at one time with a small thrust in a stable and safe manner, thereby improving the opening efficiency.

[0004] The technical solution adopted by the present invention is:

[0005] A contamination-proof raw plasma sample test tube capping machine comprises a base, on which a pushing mechanism, a test tube carrier and a carrier fixing seat for fixing the test tube carrier are provided, the pushing mechanism comprises a push rod, a push rod fixing seat for fixing the push rod and an isolation push knife, one end of the push rod is connected to the isolation push knife, the test tube carrier is provided with a plurality of slots matching the test tubes, and a diaphragm device for isolating the test tubes from the isolation push knife is provided between the isolation push knife and the test tube carrier.

[0006] Put the test tube that needs to be opened into the slot on the test tube carrier, insert the test tube carrier into the carrier fixing seat, push the push rod forward, and then drive the isolation push knife to move close to the test tube, so that the isolation push knife contacts the isolation membrane of the diaphragm device, and drives the isolation membrane to move forward close to the test tube. The isolation membrane contacts the test tube, isolates the isolation push knife from the test tube, and prevents the isolation push knife from being contaminated. The test tube carrier is fixed by the carrier fixing seat, and then the test tube is fixed. The closed test tube is mechanically pushed open by the parallel thrust of the isolation push knife, and the push rod drives the isolation push knife back to the initial position to complete an opening action.

[0007] The push knife and isolation membrane equipped with an isolation baffle can mechanically push and open the caps of closed test tubes, allowing each test tube to be opened independently to avoid cross contamination between adjacent test tubes, and to open more test tubes at a time with a small push force in a stable and safe manner, thereby improving the opening efficiency.

[0008] Furthermore, the isolation push knife is provided with a plurality of partition plates, and the partition plates cooperate with the card slots.

[0009] The isolation pusher is divided into multiple pusher cover opening areas through multiple partition plates, and the test tubes in each card slot are separated. Each test tube is opened separately to avoid cross contamination between adjacent test tubes.

[0010] Furthermore, the diaphragm device includes an isolation film, a first reel for placing the isolation film, a second reel for rolling up the isolation film and a reel fixing seat, one end of the first reel is connected to the top of the reel fixing seat, one end of the second reel is connected to the bottom of the reel fixing seat, and the starting end of the isolation film is connected to the second reel.

[0011] The closed test tube is mechanically pushed open by the parallel thrust of the isolation pusher. At this time, the isolation film may be contaminated. After the opening is completed, the push rod drives the isolation pusher back to the initial position. The first reel rolls out the clean isolation film, and the second reel rolls back the contaminated isolation film. The upper and lower film rolling method can save the use of isolation film and save costs.

[0012] Furthermore, the reel fixing seat is in a concave shape, the first reel and the second reel are arranged close to the open end of the reel fixing seat, a first auxiliary reel is arranged below the first reel, and a second auxiliary reel is arranged above the second reel, and the first auxiliary reel and the second auxiliary reel are respectively arranged away from the open end of the reel fixing seat.

[0013] By using the first auxiliary reel and the second auxiliary reel, the use area of ​​the isolation film each time can be further reduced, the use efficiency can be increased, and the use cost can be saved.

[0014] Furthermore, a baffle matching with the test tube carrier strip is provided on one side of the carrier strip fixing seat.

[0015] The baffle plate further fixes the test tube carrier bar to prevent the test tube carrier bar from shifting, thereby preventing the test tube from shifting and improving the efficiency of opening the lid.

[0016] The beneficial effects of the present invention are:

[0017] 1. Through the isolation pusher and isolation film, the closed test tubes can be mechanically pushed to open the cap, so that each test tube can be opened independently to avoid cross contamination between test tubes, and more test tubes can be opened at one time with a small push force, which is stable and safe, and improves the opening efficiency;

[0018] 2. It can effectively reduce manual workload and improve work efficiency;

[0019] 3. Through multiple partition plates, the isolation pusher is divided into multiple pusher cover opening areas, the test tubes in each card slot are separated, and each test tube is opened separately to avoid cross contamination between adjacent test tubes;

[0020] 4. By rolling the film up and down, the use of isolation film can be saved and the cost can be saved;

[0021] 5. Through the first auxiliary reel and the second auxiliary reel, the use area of ​​the isolation film can be further reduced each time, thereby increasing its use efficiency and saving use costs;

[0022] 6. The baffle is used to further fix the test tube carrier to prevent the test tube carrier from shifting, thereby preventing the test tube from shifting and improving the efficiency of opening the lid. BRIEF DESCRIPTION OF THE DRAWINGS
