Puncher for countercurrent immunoelectrophoresis agar plate

Abstract

The invention discloses a puncher for a countercurrent immunoelectrophoresis agar plate. The puncher comprises a punching tube, a fixing plate, a fixing plate frame, a handle and a negative-pressure barrel, wherein the punching tube is communicated with the negative-pressure barrel through a hose; the inner side of the opposite side of the fixing plate frame is provided with a slide path; the two ends of the fixing plate can be arranged in the slide path in a sliding mode; at least one end of the fixing plate is provided with a stirring block; the stirring block is positioned at the outer side of the fixing plate frame; a slide slot for allowing the stirring block to slide is formed in the fixing plate frame; a displacement sensor is arranged in the slide path; and a displacement display screen is arranged on the fixing plate frame or the handle. The puncher can be used for punching a plurality of holes in the agar agarose gel plate once and can automatically suck out agar in the holes, so that the whole operation can be completed by only one hand, and therefore, the puncher is efficient and convenient.

Description

technical field [0001] The invention relates to a test device, in particular to a convective immunoelectrophoresis agar plate puncher. Background technique [0002] In the operation of the convective immunoelectrophoresis test, it is necessary to place the solidified agarose gel plate on the punching template drawing and punch holes with a glass tube, and then use a pin to pick out the agarose in the hole. The current punching process has the following problems: [0003] 1. Due to the large number of holes to be punched, dozens of holes need to be punched at a time, and it takes time and effort to punch holes one by one with a glass tube, and even if there is a template drawing, there are still many holes that will be missed, which will affect the test judgment result. [0004] 2. After the drilling is completed, it is necessary to use a pin to pick out the agarose in the hole one by one, the workload is relatively large, and it is easy to damage the agarose on the agarose ...

[0003] 1. Due to the large number of holes to be punched, dozens of holes need to be punched at a time. It is time-consuming and laborious to punch holes one by one with glass tubes, and even if there are template drawings, there are still many holes that will be missed, which will affect the test results.

[0004] 2. After the drilling is completed, it is necessary to pick out the agarose in the hole one by one with a pin, and the workload is relatively large, and it is easy to damage the agarose on the agarose gel plate when picking out the agarose
