Problems solved by technology

Most of the devices use an air pump as a device to provide pressure. The air pump needs to be in working condition for a long time. The noise of the air pump is relatively large, which will seriously affect people's hearing for a long time. The vibration generated by the air pump also affects other laboratory equipment. Normal use of precision instruments

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0043] A pressure supply device such as Figure 1-4 As shown, it includes a cylinder 22 , a piston 21 , and a moving part 1 for changing the internal position of the piston 21 in the cylinder 22 . The pressure supply device is used to provide pressure for the loading air chamber of the cell loading device. The air cylinder 22 and the loading air chamber are connected through the air pressure monitoring component 3 .

[0044] Specifically, two cell loading quick-change joints 33 are connected in parallel to the loading air chamber.

[0045] One of the cell loading quick-change joints...

Abstract

A pressure supply device comprises an air cylinder, a piston, a moving part used for changing the position of the piston in the air cylinder and an air pressure monitoring part. The air pressure monitoring part is connected with the air cylinder and a loading air chamber; the first pressure sensor detects the pressure of the loading air chamber; the output end of the cylinder is connected with an input end of a three-way pipe through a first pipeline; a first output end of the three-way pipe is connected with an input end of a first electromagnetic valve; an output end of the first electromagnetic valve is connected with the loading air chamber; a second output end of the three-way pipe is connected with an input end of a second electromagnetic valve; an output end of the second electromagnetic valve is connected with external atmosphere; a second pressure intensity sensor is arranged on a first pipeline and used for detecting the pressure of the first pipeline. The pressure supply equipment can provide accurate pressure for the cell loading device and detect the pressure. The prior art using an air pump as an air source is changed, so that noise and vibration are greatly reduced; positive pressure or negative pressure can be provided; and the pressure compensation function is achieved.

Description

technical field [0001] The invention relates to the field of cell mechanics, in particular to a pressure supply device and a cell loading device using the device. Background technique [0002] At present, in vitro cell culture provides an ideal research method for studying the influence of various physical and biochemical factors on human tissues. The loading methods of cells in vitro mainly include: fluid shear stress loading method, pressure loading method, and strain loading method. Most of the devices use an air pump as a device to provide pressure. The air pump needs to be in working condition for a long time. The noise of the air pump is relatively large, which will seriously affect people's hearing for a long time. The vibration generated by the air pump also affects other laboratory equipment. Normal use of precision instruments. [0003] Therefore, based on these problems, there is an urgent need for a pressure supply device to solve the above problems. Contents...
