Abstract

The invention discloses a medical examination sampling device including a sampling negative pressure box; one side face of the sampling negative pressure box is provided with a pressure reduction pump, and the pressure reduction pump is connected with a pressure reduction interface of the sampling negative pressure box through a guide pipe; the top of the sampling negative pressure box is provided with a plurality of sampling pipe connectors, and a sampling funnel is arranged below each sampling pipe connector; the bottom of the sampling negative pressure box is provided with a plurality of sampling bottle connectors. According to the medicine examination sampling device, air in the sampling negative pressure box is pumped out through the pressure reduction pump; due to the negative pressure generated in the sampling negative pressure box, samples go into the sampling negative pressure box through the sampling pipe connectors; due to the gravity, the samples flow into the corresponding sampling funnels and go into sampling bottles through the sampling bottle connectors, so as to preventing the samples from being mixed with air during sampling; and moreover, the device can control the number of opening and closing electromagnetic valves in corresponding sampling pipe connectors and sampling bottle connectors through a controller according to the needs, so as to achieve sampling of multiple samples.

Description

A kind of medical test sampler
Technical field
The present invention relates to medical test apparatus technical field, be specially a kind of medical test sampler.
Background technology
At present, medical science sampling pipette, it is made up of glass pipette and the imbibition air bag being arranged on glass pipette upper end, and the sampling pipette of prior art exists following defect: because suction pipe is glass material, its suction nozzle end is easily damaged; In imbibition process, liquid easily aspirates in imbibition air bag, causes the virus in liquid or miscellaneous bacteria to remain, affects Detection results; Imbibition cannot be quantitative, need graduated cylinder with the use of, so there has been medical test sampler, but existing medical test sampler is easy mixing air when sampling, and can only carry out the sampling of single sample, for this reason, we propose a kind of medical test sampler.
Summary of the invention
The object of the present invention is to provide a kind of medical test sampler, to solve the problem proposed in above-mentioned background technology.
