Technical Field

The invention belongs to the technical field of auxiliary instruments for medical inspection departments; in particular to a working method of a tube opening instrument for a medical examination laboratory.

Background

The PCR polymerase chain reaction is a molecular biology technique for amplifying and amplifying specific DNA fragments, which can be regarded as special DNA replication in vitro, and the biggest characteristic of PCR is that trace amount of DNA can be greatly increased. At present, a biological or medical laboratory often utilizes PCR to verify genetic materials, particularly in biological and medical inspection related mechanisms, the PCR is very frequently applied, at present, domestic related mechanisms mostly manually open PCR tubes, aiming at some mechanisms with a large number of PCR, workers need to frequently open the PCR tubes, at present, PCR tubes are mostly 200 mu L small tubes, the PCR tubes need to be opened by operators carefully when being opened, and the frequent opening causes hand fatigue due to small opening protrusions and large force; some operators use table corners and the like to open, so that certain pollution is easily caused, and the problems that the liquid in the interior is shaken and splashed out and the like are easily caused.

According to above problem, the technical scheme that patent number is CN 108380258A has provided a medical science inspection laboratory with a tub apparatus of opening, the machinery that this patent proposed is to place PCR pipe in the device, fixes PCR pipe through twisting the screw, then presses and pulls the switch and open PCR pipe, the personnel that this technical scheme effectively solved frequently open the fatigue that leads to the hand, utilize the table angle etc. to open the pollution that leads to PCR pipe and the manual work is opened and is leaded to inside liquid easily to rock the scheduling problem that splashes.

However, according to the technical scheme of the patent, the screw is required to be repeatedly screwed when the PCR tube is assembled and disassembled, so that the assembling and disassembling time of technical personnel is greatly prolonged, the screw is frequently screwed by personnel to cause hand fatigue, and meanwhile, the screw cannot be judged by screwing when the personnel are fatigued, so that the PCR tube is easily crushed by the screw, and further, the medicament is scattered to cause waste and pollution, meanwhile, the technical scheme of the patent has no special design for opening the PCR tube and opening a plurality of PCR tubes, when a plurality of PCR tubes are required to be used, the technical scheme of the patent can only be completely opened, and cannot be independently opened in the plurality of PCR tubes, so when a plurality of PCR tubes are used and the plurality of PCR tubes are required to be used in sequence, all PCR tubes can be opened by adopting the technical scheme of 108380258A, and further, the PCR tubes which are not required to be used are polluted, therefore, an open tube apparatus which can individually open a plurality of PCR tubes to open the plurality of PCR tubes at one time, rapidly assemble and disassemble the PCR tubes, and does not need to manually fix the PCR tubes is urgently present.
