Profound hypothermia tube picking workstation for biological samples

Abstract

The invention discloses a profound hypothermia tube picking workstation for biological samples. The profound hypothermia tube picking workstation comprises a shell and a platform in the shell, whereina tube picking area is arranged above the platform, and a transfer barrel conveying area is arranged below the platform; the platform is provided with a liquid nitrogen tank corresponding hole and atransfer barrel butt joint hole; the transfer barrel conveying area is provided with a liquid nitrogen tank and a transfer barrel conveying mechanism; the shell is provided with a conveying opening corresponding to one end of the transfer barrel conveying mechanism; a tank opening of the liquid nitrogen tank is in butt joint with the liquid nitrogen tank corresponding hole, a positioning plate isfixed in the liquid nitrogen tank and provided with a tube picking receding groove; a sample box clamping manipulator, a test tube clamping manipulator and a tube jacking mechanism are arranged in thetube picking area; and the tube jacking mechanism comprises a test tube jacking rod which extends below the positioning plate in the liquid nitrogen tank and is used for jacking a test tube from thebottom end of a sample box, and the test tube jacking rod is connected with a jacking rod driving device. According to the profound hypothermia tube picking workstation, centralized tube picking of multiple storage devices is achieved, the device utilization rate is high, the tube picking efficiency is high, the layout in the workstation is reasonable, the structure is compact, and the overall size and occupied space of the workstation are small.

Description

technical field

[0001] The invention belongs to the technical field of biological sample storage, and in particular relates to a biological sample deep-low temperature pipe picking workstation. Background technique

[0002] In the field of biomedicine, sample cryopreservation equipment is used for cryogenic storage of biological samples such as blood samples, vaccines, bacteria and viruses, etc., so that the samples are kept in liquid nitrogen for long-term active storage. There are multiple sample boxes stored in the device, and multiple test tubes are arranged and stored in the sample box, and the samples that need to be stored are in the test tubes.

[0003] In the current cryopreservation equipment, most of the sample boxes are stored and taken out. When individual test tubes need to be taken out, the sample box containing the test tube can only be taken out from the equipment, and the required test tubes are taken out at room temperature. will destroy other unused samp...
