Description

Technical Field

[0001] The utility model relates to the technical field of perfusion tube fixing devices, in particular to a patch clamp perfusion tube fixing device. Background Art

[0002] Perfusion is to insert a thin tube into a cell and inject liquid to replace the cytoplasm with artificial liquid. A perfusion tube fixing device is required during the perfusion process.

[0003] Among them, a Chinese patent for a patch clamp perfusion tube fixing device, with the application number <2023216>49283.3>, includes a bottom plate. A bracket is fixedly installed on the top of the bottom plate. The number of brackets is two, and they are symmetrically distributed front and back. A box body is movably sleeved on the outside of the two brackets. A worm is rotatably connected to the rear side of the inner cavity of the box body. A rotating rod is rotatably connected to the middle of the bottom of the inner cavity of the box body. A convex block is fixedly sleeved on the outside of the rotating rod. A worm gear is fixedly installed on the top of the rotating rod. The worm gear meshes with the worm. Limit rods are fixedly installed on the front side and the rear side of the bottom of the inner cavity of the box body. A clamping rod is movably sleeved on the outside of the limit rod. The utility model can quickly clamp the drainage tube, is convenient and fast to operate, improves the use efficiency of the device, can also adjust the use height of the device, effectively avoids the situation of bending and knotting under the drainage tube, has a simple structure and is convenient to operate, and improves the practicability of the device.

[0004] The above patent has improved the perfusion tube fixing device, which can clamp the perfusion tube and adjust the use height of the device. However, there are still deficiencies. The circumferential adjustment ability of the fixing device is poor. When in use, when the direction and position of the perfusion tube are different, the overall fixing device needs to be moved so that the clamping block faces the perfusion tube to clamp the perfusion tube. It is necessary to continuously adjust the position of the patch clamp perfusion tube fixing device to adapt to the direction and position of the perfusion tube. Otherwise, the situation of bending and knotting will still occur under the perfusion tube. And adjusting the position of the patch clamp perfusion tube fixing device is quite cumbersome to operate. Therefore, we propose a patch clamp perfusion tube fixing device. Summary of the Utility Model
