Pipe opening instrument for medical examination laboratory

Abstract

The invention relates to the technical field of pipe opening instruments for medical examination laboratories, and discloses a pipe opening instrument for a medical examination laboratory. The pipe opening instrument comprises a storage box, containing grooves in a rectangular array are formed in the top of the storage box, pipe bodies are placed in the containing grooves, cover bodies are arranged at the tops of the pipe bodies, cover opening units are arranged on the side walls of the adjacent tops of the containing grooves, one end of each cover opening unit keeps arc motion, the cover opening units lock the cover bodies, horizontally-distributed bearing units are arranged in the containing grooves, the bearing units are provided with locking units used for driving the cover opening units to keep the horizontal state, transmission units are arranged in the containing grooves, the transmission units are assembled to be in the manner than when one cover opening unit and the cover body assembled with the cover opening unit tend to be in the horizontal state, the transmission units drive the adjacent cover opening unit and the cover body assembled with the cover opening unit to keep the arc motion till the cover body is perpendicular to a pipe opening of the corresponding pipe body, the cover bodies can be opened at a large angle, when the previous pipe body is closed, the last pipe body is opened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tube opening instruments for medical testing laboratories, in particular to a tube opening tool for medical testing laboratories. Background technique [0002] PCR tubes are commonly used consumables in the medical testing process, and their main function is to provide containers for the polymerase chain reaction. A common PCR tube is composed of a tube body and a cover body, the tube body and the cover body are connected together, and there are protrusions on the cover body. [0003] According to the patent No. 202010546817.4, a tube opening instrument for medical testing laboratory is disclosed. The tube fixing frame to be opened is embedded in the upper end surface of the tube to be opened. The fixed frame of the tube to be opened is evenly arranged on the upper end surface of the tube to be opened, so that the present invention can uncap the tubes to be opened with different sizes and lengths, greatl...

Problems solved by technology

[0004] The disadvantage of the prior art is that in the above-mentioned patent, when the cover is opened, the sealing cover is opened by the pry plate, but after the seesaw pries the sealing cover, the angle between the sealing cover and the horizontal mouth of the PCR tube If it is less than 90 degrees, the suction gun cannot be inserted into the PCR tube. If the operator removes the sealing cap by hand or other instruments, the liquid in the tube will be polluted. Opening will cause some PCR tubes to be unusable after opening, causing dust to fall into them, thus affecting the test results
