Problems solved by technology

[0002] In clinical testing instruments, it is necessary to use negative pressure as a power source to attract specimens, reagents, and drive mechanical parts to perform corresponding actions. At present, the negative pressure systems of instruments on the market use compressors to provide negative pressure through negative pressure storage tanks. During the working process, if the liquid is sucked, it will accumulate in the negative pressure storage tank and be discharged regularly. In actual operation, it is often the case that the liquid is not discharged in time and the liquid is sucked into the compressor and the pressure regulating device, causing great losses. Pressure storage tanks take up a lot of space and are cumbersome to operate

Embodiment approach

[0016] Depend on figure 1 Shown, a kind of embodiment of the present invention is:

[0017] A negative pressure automatic protection device, including a negative pressure intake pressure adjustment device and a compressor, a negative pressure output device is provided between the negative pressure intake pressure adjustment device and the compressor, and a negative pressure output device is also provided on the negative pressure output device An isolation bottle 1 is installed, and the bottle cap of the isolation bottle 1 has a negative pressure inlet 2 and a negative pressure outlet 3. The negative pressure inlet 2 is in the middle of the isolation bottle 1 and connected to a bell mouth 4 at the lower end, and a hollow plastic is arranged inside the isolation bottle 1. The gap between the floating ball 5, the bell mouth 4 and the inner wall of the isolation bottle 1 is smaller than the diameter of the floating ball 5. Under normal conditions, the floating ball 5 is located un...

Abstract

The invention provides a negative pressure automatic protection device, which comprises a negative pressure intake pressure regulating device and a compressor, wherein a negative pressure output device is arranged between the negative pressure intake pressure regulating device and the compressor; an isolation battle is arranged on the negative pressure output device; and an automatic drainage device is arranged in the isolation bottle. The negative pressure automatic protection device can effectively prevent liquid from being absorbed into the compressor, a pneumatic adjusting device and the like, so that great loss is avoided; and the space of an instrument is saved for a blood sample clot filtering device for noise reduction treatment of the compressor.

Description

technical field [0001] The invention relates to a negative pressure automatic protection device. Background technique [0002] In clinical testing instruments, it is necessary to use negative pressure as a power source to attract specimens, reagents, and drive mechanical parts to perform corresponding actions. At present, the negative pressure systems of instruments on the market use compressors to provide negative pressure through negative pressure storage tanks. During the working process, if the liquid is sucked, it will accumulate in the negative pressure storage tank and be discharged regularly. In actual operation, it is often the case that the liquid is not discharged in time and the liquid is sucked into the compressor and the pressure regulating device, causing great losses. Pressure storage tanks take up a lot of space and are cumbersome to operate. Contents of the invention [0003] In view of the above reasons, the purpose of the present invention is to overco...
