Accurate liquid suction proportioning system

Abstract

The invention provides an accurate liquid suction proportioning system, and belongs to the field of medical devices. The system comprises a suction loading and unloading rail stretching across all stations. A slidable suction loading and unloading mechanical arm is arranged on the suction loading and unloading rail; an upper suction sliding block and a lower suction sliding block which are independently driven by a driving device are arranged on a suction mechanical arm base, an upper suction positioning block used for clamping the end of a suction device suction rod is arranged on the upper suction sliding block, and a lower suction positioning block used for clamping a suction device suction sleeve is arranged on the lower suction sliding block. And through the arranged suction loading and unloading system, automatic proportioning of liquid can be achieved, automatic loading and unloading of test tubes are achieved, and the efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a precise liquid suction proportioning system. Background technique [0002] For patients receiving artificial insemination or in vitro fertilization and embryo transfer, the spouse's semen needs to be optimized by washing to remove impurities such as seminal plasma, immotile sperm, and white blood cells, and to extract motility and high-quality sperm for fertilization. [0003] Defects of the prior art: At present, no matter which method is used to optimize semen washing, it is all manual operation, and manual operation has the following limitations: [0004] 1. Repeating the same operation requires heavy workload, long time and low efficiency. For example, a center washes and optimizes semen for about 30 people every day, and at least two people need to repeat the same operation process every day, and it will take at least one whole morning to complete. [0005] 2. The curren...

[0003] Defects of the prior art: At present, no matter which method is used to optimize semen washing, it is all manual operation, and manual operation has the following limitations:

[0005] 2. At present, manual operation, for the amount of washing semen, the various washing liquids added cannot be accurately quantified, resulting in inaccurate calculation of the concentration of semen after washing, and it is necessary to re-evaluate and then adjust the concentration of semen after washing for fertilization

[0006] 3. There is also a plan to add negative pressure adsorption equipment, but it is difficult to ensure the accuracy of the amount added in this plan

Especially when it comes to the need to extract a certain amount of liquid from one container, and then inject it into another container, and each extraction device can only be used once, so as not to pollute other liquids, the existing operations are manual operations

In the Chinese patent document CN110358673A, a cell separation system and method are described, and the suction operation is realized through the lifting device and the syringe, but this scheme is very inconvenient in the process of needing to replace the suction device

Moreover, setting the pipeline will affect the accuracy of the liquid suction volume, resulting in inaccurate liquid ratio, because the pipeline itself also has a certain capacity
