Technical Field

The invention relates to the technical field of medical instruments, in particular to a raw plasma sample specimen test tube cover opener.

Background

The prepared main bag of raw material plasma and the connected sample tube are adhered with the same bar code of a plasma donor, and the sample tube is thermally sealed before quick freezing, so the sample-remaining test tube is provided with a section of hose, the conventional test tube uncapping machine cannot be used for automatically uncapping the test tube, the test tube can be uncapped only manually at present, both hands are needed to operate the uncapping, one hand is held tightly by the other hand to open the test tube, time and labor are wasted, the uncapping difficulty is large for the manual work, one carrying strip needs to be inserted after the uncapping is completed, and the repeated actions are multiple and complicated; in addition, the plasma in the test tube is inevitably splashed out in the process, so that the risk of biological pollution is caused; moreover, for a large-scale biological product enterprise, the number of the samples to be detected which need to be processed every day is 10000, and for the manual uncapping processing of the sample test tubes to be detected before the experiment, the number is huge, so that the workload of workers is extremely large, and the working intensity is extremely high.

If can adopt the automatic uncapping of uncapping machine before carrying out the experiment to this kind of special sample test tube of waiting, will significantly reduce experimenter quantity and alleviate manual work volume and intensity of labour to reduce plasma biological contamination and cross contamination's possibility by a wide margin.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides the raw plasma sample reserving test tube uncapping machine which has the advantages that a plurality of test tubes can be easily and automatically uncapped at one time, safety and no pollution are realized, the investment of experimenters is greatly reduced, the manual workload and the labor intensity are reduced, and the like.

In order to solve the technical problems, the technical scheme of the invention is as follows: a raw plasma sample test tube cap opener comprises an electric push rod, a fixed seat and a test tube carrier strip arranged on the fixed seat, wherein the electric push rod is arranged on one side of the fixed seat and the test tube carrier strip, the electric push rod comprises a driver, a box body and push rods, the driver and the push rods are arranged on two sides of the box body, one ends of the two push rods, which are close to the test tube carrier strip, are connected through a push plate, film rolling fixed seats and film rolling motors arranged inside the film rolling fixed seats are further arranged on two sides of the box body, and a film outlet mechanism and a film return mechanism are respectively arranged on the two film rolling fixed seats; the test tube carrier strip comprises a fixed seat and a plurality of side plates, wherein the fixed seat comprises a bottom plate and two side plates arranged on two sides of the bottom plate, guide grooves are formed in the inner side walls of the two side plates, first grooves matched with the guide grooves are formed in two sides of the test tube carrier strip, second grooves with the concave directions back to the fixed seat are formed in the bottom of the test tube carrier strip, through holes communicated with the bottom of the test tube carrier strip are formed in the bottom plate, gears and driving motors are installed at the through holes, and racks meshed with the gears are arranged at the bottom of the test tube carrier strip; the test tube carrier strip is provided with a placing groove for placing a test tube, a first stop block and a second stop block are respectively arranged on two sides of the test tube carrier strip, a supporting seat is arranged between the first stop block and the film rolling fixing seat, a film rolling supporting rod is arranged on the supporting seat, and the film rolling supporting rod, the film discharging mechanism and the film returning mechanism are connected through a rolled film; and a power supply and a PLC are also arranged on two sides of the box body.

During the use, place a roll membrane on rolling up the membrane fixing base, and it is taut through rolling up the membrane bracing piece, insert the test tube carrier strip on the fixing base, the standing groove of test tube carrier strip is put into to the test tube, switch on, the test tube carrier strip reachs the assigned position, electric putter promotes forward, make electric putter contact roll membrane, roll up the test tube in the membrane contact test tube carrier strip, test tube one side contact first dog in the test tube carrier strip, opposite side contact second dog, make test tube lid and test tube separation under the effect of thrust, accomplish uncapping, the gear is geared with the rack of test tube carrier strip lower part, drive motor drive gear rotates after accomplishing uncapping, make the test tube carrier strip move forward, simultaneously roll up membrane motor drive and return membrane mechanism and go out membrane mechanism and accomplish and receive the membrane and go out the membrane, continue uncapping next time.

The cover can be opened stably and safely by adopting a high-quality electric push rod; the test tube strip carrier is directly used for loading, a rotating frame is not needed, and time and labor are saved; the driving motor drives the test tube carrying strip to automatically advance or retreat and automatically start and stop, a plurality of test tubes can be uncovered at one time, and the efficiency is extremely high; install disposable contact articles for use between electric putter and test tube carrier strip additional and roll up the membrane, and for automation equipment, can avoid push rod and test tube contact and when uncapping the cross contamination that probably causes in the plasma splashes.

Preferably, the first stopper has a gamma shape, the second stopper has a gamma shape, and the first stopper and the second stopper are disposed at both sides of the test tube carrier strip in a high-low manner.

The first stop dog is a gamma shape, the second stop dog is a gamma shape, the first stop dog and the second stop dog form a clamping structure, the first stop dog and the second stop dog are arranged at two sides of the test tube carrier strip in a high-low mode, the test tube in the test tube carrier strip is fixed at a specified position, and the electric push rod can open the cover more stably.

Preferably, the placing groove is cylindrical, and an opening is formed in one side of the placing groove close to the second stopper along the length direction of the placing groove.

The standing groove is cylindrical and is convenient for place the test tube, at one side opening of standing groove, is convenient for wash and remove dust.

Preferably, the tops of the film outlet mechanism and the film return mechanism are respectively hinged with a lock catch.

When placing a roll membrane, break off the hasp upwards, place and detain the hasp downwards after rolling up the membrane, easily install a roll membrane, and prevent at the in-process of uncapping, thereby roll up the influence of membrane landing and uncap.

Preferably, a dustbin is arranged on one side, away from the test tube carrying strip, of the second stop block.

The dustbin is used for receiving the test tube lid that the in-process of uncapping dropped, avoids the test tube lid to drop at will, and the residual thick liquid that the test tube was covered splashes, causes the polluted environment.
