Description

Technical Field

[0001] The utility model relates to the technical field of traction supports, in particular to a device for stripping off the membrane during the culture process of primary spinal cord neurons. Background Art

[0002] The spinal cord is covered with three layers: the dura mater, the arachnoid mater, and the pia mater. Microscopically stripping the spinal cord membranes must be performed on ice and quickly to prevent liquefaction of the spinal cord. Conventional dissecting microscopes project light from below, but stripping requires both sufficient light and ice. Therefore, a device is needed to meet these two requirements.

[0003] Currently, there is no unified and perfect device for removing the spinal cord membrane. The use of ordinary ice packs will affect the light transmittance of the microscope, resulting in incomplete membrane removal and serious impact on cell purity. In addition, the device is inefficient and not conducive to its widespread use.

[0004] Therefore, the utility model provides a device for stripping the membrane during the culture process of primary spinal cord neurons. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art that the use of ordinary ice bags will affect the transmittance of the microscope, resulting in unclean membrane stripping and seriously affecting the purity of cells. A device for stripping the membrane during the culture of primary spinal cord neurons is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a device for stripping the membrane during the culture of primary spinal cord neurons, comprising a base, a microscope fixedly mounted on the top of the base, a water guide groove provided on the outside of the base, a through hole provided on the inner wall of the water guide groove, a placement groove provided on the top of the base, a round table fixedly mounted on the inner wall of the placement groove, a disc fixedly mounted on the inner wall of the placement groove, a culture dish provided on the top of the disc, ice cubes provided on the inner wall of the culture dish, and a sealing cover provided on the top of the culture dish.

[0007] Preferably, four threaded tubes are fixedly mounted on the bottom of the base, and the inner walls of the four threaded tubes are all threadedly connected with anti-slip pads.

[0008] Preferably, a circular groove matching the diameter of the frustum is opened in the middle of the disc, and the frustum is arranged on the inner wall of the circular groove.

[0009] Preferably, a notch is provided on the top of the microscope, and the through hole is communicated with the inner wall of the placement groove.

[0010] Preferably, a handle is fixedly installed on the top of the sealing cover, the culture dish and the sealing cover are both made of glass, and the ice cube is set below the microscope.

[0011] Preferably, the outer edge of the anti-slip pad is evenly provided with a plurality of protrusions, and the anti-slip pad is made of rubber.

[0012] In summary:

[0013] 1. In the present invention, a culture dish filled with water is placed in a refrigerator at -20 degrees Celsius until it is completely solidified to form ice cubes. The culture dish can then be placed on top of the disc. The culture dish containing the spinal cord tissue can then be placed on top of the ice cubes, thereby ensuring perfect light transmission, ensuring the efficiency of the membrane peeling, and ensuring that the tissue will not liquefy under low temperature conditions.

[0014] 2. In the utility model, the water that seeps out after the ice melts when the film is peeled off can be discharged to the outside through the through hole and the water guide groove. The user can use his fingers to press the disc to take it out to the outside through the notch, thereby facilitating the disc to be taken out to the outside for cleaning and maintenance. The distance between the anti-slip pad and the threaded tube can be adjusted by rotating the anti-slip pad, thereby facilitating fine adjustment of the height of the base, and the four anti-slip pads can be adjusted to not be at the same height, thereby ensuring stable placement on an uneven table.
