A foot-operated reagent injector

Abstract

The invention relates to a foot step type reagent infusion instrument. The instrument comprises a box, a water tank is arranged on the box, and a tap water outlet pipe and a reagent discharging pipe are arranged on one side of the water tank; a waste liquid storage tank is arranged under the water tank in the box; N reagent storage tanks are arranged in the box and connected with a multi-way pipe fitting through first transmission pipes respectively, and the multi-way pipe fitting is provided with N+1 joints and connected with the reagent discharging pipe through a second transmission pipe; a solenoid valve is connected to each first transmission pipe, a water pump and a flowmeter are arranged on the second transmission pipe, and the water pump is driven by a stepping motor; the box is further provided with a touch display screen and a PLC connected with the touch display screen, and the solenoid valves, the stepping motor and the flowmeter are connected with the PLC through signal lines respectively. The foot step type reagent infusion instrument has the advantages of being reasonable in structure, convenient to operate and use and good in safety.

Description

technical field [0001] The invention relates to a foot-operated reagent injector, which belongs to the technical field of reagent perfusion instruments. Background technique [0002] Biology or chemistry is an experimental discipline, which has the characteristics of large investment, slow return and strong uncertainty. It needs a lot of experiments and a lot of manpower and material resources to promote its development and progress. Fortunately, in recent years, with the increase of national investment and the entry of social capital, my country's biochemical industry has made remarkable progress. With the rapid development of the biochemical industry, higher requirements are put forward for the experimental instruments and equipment closely related to the biochemical industry. [0003] In the biological and chemical laboratories of schools and hospitals, a large number of experiments are carried out every day, and a large amount of chemical reagents need to be used. Among...

Problems solved by technology

However, most of the existing infusion sets are simple in structure and function. Although the technical problems of reagent perfusion have been solved to a certain extent, they have the disadvantages of inconvenient operation and poor safety, which cannot meet the requirements of the rapidly developing biochemical industry. industry requirements
