Collecting bacteria enrichment driving device with access selection function

Abstract

The invention provides a collecting bacteria enrichment driving device with an access selection function. The collecting bacteria enrichment driving device comprises a driving device body, a pump head, a clamping block and an access control device. The driving device body is fixed to a rack. The pump head is provided with a roller which is driven by the driving device body. The clamping block is provided with a body, and the body is provided with a notch corresponding to the roller in shape in the direction facing the pump head. The clamping block is driven by a driving piece connected with the rack so that the clamping block can move towards the pump head. A stopping part extends from the position, at the inlet of the hose, of the clamping block in the tangential direction of the roller. The access control device is arranged at the inlet of the hose, corresponds to the stopping part and is driven by a driving mechanism so that the hose can enter the pump head. The access control device controls the hose to be on or off when clamped and abutted by the roller and the clamping block to deliver a sample in the hose.

Description

technical field [0001] The invention relates to a bacteria collection and enrichment drive device, in particular to a bacteria collection and enrichment drive device with channel selection. Background technique [0002] At present, most of the bacteria collection driving devices in microbial detection and enrichment are peristaltic pumps, which can transport the drug or culture in the hose to other devices by crushing the hose through the pump head, but the number of hoses in the peristaltic pump Corresponding to the number of filters to be tested, there are often more than two, generally three. However, the existing peristaltic pumps can only transport the drug or culture to be tested in the hose and cannot select the channel for it. Take the existing triple pipeline in microbial detection and enrichment as an example, because it requires three filters, two of which are loaded with the same sample, and the other is loaded with other samples, the pipeline often needs to be c...

Problems solved by technology

[0002] At present, most of the bacteria collection driving devices in microbial detection and enrichment are peristaltic pumps, which can transport the drug or culture in the hose to other devices by crushing the hose through the pump head, but the number of hoses in the peristaltic pump Corresponding to the number of filters to be tested, there are often more than two, generally three, but the existing peristaltic pumps can only transport the drug or culture to be tested in the hose and cannot select the channel

Take the existing triple pipeline in microbial detection and enrichment as an example, because it requires three filters, two of which are loaded with the same sample, and the other is loaded with other samples, the pipeline often needs to be connected with one circuit and two circuits or two channels with two circuits. The one-way transportation method is convenient for the follow-up of microbial detection and enrichment. At this time, the peristaltic pump cannot meet the drive and at the same time switch the pipeline, which leads to the need to repeatedly clamp the tube and replace the hose, which affects the microbial detection and enrichment. Realization of automation reduces work efficiency
