Connector, transfer device, installation method and use method of the transfer device

Abstract

The invention relates to a connector, a transfer device and a mounting method and use method of the transfer device. The connector comprises a connecting sleeve and a connecting piece and a filter element; through holes are formed in the connecting sleeve and penetrate through the connecting sleeve in the axial direction; the through holes comprises the first through hole, the second through hole and the third through hole, wherein the first through hole, the second through hole and the third through hole are communicated in sequence from top to bottom; a connecting hole is formed in the connecting piece and penetrates through the connecting piece in the axial direction, and the connecting piece is arranged in the third through hole of the connecting sleeve; the filter element is arranged in the second through hole of the connecting sleeve. The transfer device comprises the connector, a micro tube and a blow and suction device. The connector is simple in structure, convenient to use, good in sealing effect and safe and can operate with the micro tube with various sizes, assembly and operation are convenient, existing tools, sample contamination risks which may occur in the use of the tools and the installation time of the tools are greatly reduced, and the operation process of an IVF laboratory is simplified.

Description

technical field [0001] The invention relates to the technical field of physical handling and transfer of samples, in particular to a connector device used for physical handling and transfer of samples such as biological and medical laboratory cells, in particular to a connector, a transfer device and the transfer device How to install and how to use. Background technique [0002] At present, the processing steps for oocytes and gametes in IVF (assisted reproductive technology) laboratories usually include the following: [0003] Collection of oocytes: after egg retrieval, the follicles contain several egg-corona-mound complexes of the patient, with some tissues, blood clots, etc., and the oocytes need to be identified and cleaned under the microscope as soon as possible. It is transferred to egg culture or fertilization culture. In this process, an egg-picking tool with a diameter of 120-180um is required to clean the oocytes and transfer them to the corresponding culture ...

AI Technical Summary

Problems solved by technology

The former is prepared by laboratory operators in advance. The possible problems of this method are: 1. It takes a long time for the operator to complete the preparation work, including drawing and connecting the rubber head that provides suction

2. There is a risk of contamination in the process of drawing preparation and installing the rubber head, which increases the chance of cross-contamination

However, there are the following problems in the transfer of the finished egg stripping needle: 1. The finished egg stripping needle needs to be loaded on the special stripping needle handle for the next operation, which takes a certain amount of loading time and is not easy to use.

2. The diameter of the finished egg stripping needle is relatively fixed. If the patient's eggs or embryos are too large or too small, they cannot be operated well.

In the prior art, the diameter of processing cells or embryos needs to be 80-180um. Regardless of using a Pasteur pipette or a capillary glass tube, it needs to be reprocessed to draw the lumen into a suitable inner diameter and then connect the corresponding rubber head for operation. The connection process Time-consuming and complicated (you need to manually connect the Pasteur pipette or capillary glass tube to the rubber tip or other connection tools)
