Tube opening instrument for medical examination laboratory

Abstract

The invention discloses a tube opening instrument for a medical examination laboratory. To-be-opened tube fixing frames are arranged for rapidly assembling and disassembling to-be-opened tubes, so that the burden of workers is reduced. The to-be-opened tube fixing frames are clamped with springs, so that a buffer capacity is achieved, and breaking caused by excessive clamping of the to-be-opened tubes is avoided. A tube opening seat base, a tube opening seat and a base are arranged, so that the height and position of tube opening heads are adjustable, the tube opening instrument can be used for uncapping the to-be-opened tubes with different sizes and lengths, and the use range and practicability of the tube opening instrument are improved. The tube opening instrument can be used for conducting uncapping operation on a single to-be-opened tube and can also conduct the uncapping operation on multiple to-be-opened tubes, and the interiors of the to-be-opened tubes are prevented against contamination. The tube opening heads are arranged, fatigue caused by frequently opening the to-be-opened tubes and contamination of PCR tubes caused by opening the tubes through desk corners and the like are avoided; and the to-be-opened tube fixing frames can be used for stably clamping the to-be-opened tubes, so that the situation that internal liquid shakes and splashed out due to manual opening is avoided.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment used in medical testing departments; in particular, it relates to a tube opening device used in medical testing laboratories. Background technique [0002] PCR polymerase chain reaction is a molecular biology technique used to amplify specific DNA fragments. It can be regarded as a special DNA replication outside the body. The biggest feature of PCR is that it can greatly increase a small amount of DNA. At present, biological or medical laboratories often use PCR to verify genetic material, especially in biological and medical inspection-related institutions, where PCR is used very frequently. At present, most relevant domestic institutions open PCR tubes manually. Personnel need to open the PCR tubes frequently. At present, most of the PCR tubes are small tubes of 200 μL. When opening, the operator needs to open them very carefully. Because the opening protrusion is small and the forc...

Problems solved by technology

[0004] However, in the technical solution of this patent number, the PCR tube is fixed by turning the screw. When the PCR tube is loaded and unloaded, the screw needs to be screwed repeatedly, which greatly increases the loading and unloading time of the technicians, resulting in frequent screwing of the personnel. Fatigue of the hand, and at the same time, when the personnel are tired, the screw cannot be judged, which can easily cause the PCR tube to be crushed by the screw, and then cause the medicine to spill, causing waste and pollution. And there is no special design for the opening of multiple PCR tubes. When multiple PCR tubes need to be used, the technical solution of this patent number can only be fully opened, and it cannot be opened separately in multiple PCR tubes. Therefore, when using multiple PCR tubes When multiple PCR tubes need to be used sequentially, the technical solution of 108380258A will open all the PCR tubes, which will cause other PCR tubes that are opened and not used to be polluted. Therefore, a single PCR tube that can be opened separately The emergence of tube opening devices that can open multiple PCR tubes at one time, quickly load and unload PCR tubes, and do not need to manually fix PCR tubes is imminent.
