Problems solved by technology

The experimental device for sampling brain slices that is generally used now (as shown in the attached manual) figure 2 As shown), ordinary droppers are generally used. Due to the small diameter of the pipette, it is easy to cause the brain slices to be distorted and deformed. Some people directly use a small spoon, which will easily damage the brain slices during operation and cause the experiment to fail.

Abstract

The invention discloses a spring-type brain slice sampler and a sampling method thereof. The sampler comprises a glass suction head, a curved tube and a controllable piston component. The circular end of the curved tube is connected to the controllable piston component through a connecting head. , the other end of the curved tube is connected with the glass suction head; the controllable piston part includes a top, a connecting rod and a piston body, the upper end of the piston body is movably connected with the top of the piston through a connecting rod, and a spring is arranged in the piston body. One end of the spring is movably connected with the piston connecting rod through the movable panel, and the other end of the spring is fixed on the fixed panel at the lower end of the piston body. The sampling method is to put the suction head close to the brain slice and press the top of the piston lightly, and then slowly release it to suck the brain slice. The invention provides a brain slice sampler with compact structure, simple operation, stable and reliable structure for relevant professional scientific research experiments, improves the efficiency of brain slice transfer and minimizes damage to the brain slice for researchers in neuroelectrophysiology experiments, and improves the the survival rate of brain slices.

Description

technical field [0001] The invention relates to a brain slice electrophysiological experiment device, in particular to a spring type brain slice sampler and a sampling method thereof. Background technique [0002] At present, in colleges and universities and scientific research institutions, electrophysiological experiments in many related majors require experiments on memory, sleep, thinking activities, and brain functions. Experimental Study. The experimental device for sampling brain slices that is generally used now (as shown in the attached manual) figure 2 As shown), ordinary droppers are generally used. Due to the small diameter of the pipette, it is easy to cause distortion of the brain slices, and some people directly use a small spoon, which will easily damage the brain slices and cause the experiment to fail. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to solve the deficiencies in the prior art and provi...
