Abstract

The invention discloses a negative-pressure device with a pressure display function. The negative-pressure device comprises a hollow cavity body provided with a negative-pressure inner cavity and a closed device positioned at an opening of the hollow cavity body, and is further provided with a negative-pressure display device used for displaying negative pressure in the hollow cavity body. The negative-pressure device with the pressure display function can display a negative pressure situation in the hollow cavity body in real time through the negative-pressure display device arranged in or on the hollow cavity body, so that medical personnel can conveniently observe whether the negative-pressure device is in an effective state or not and the nursing workload of the medical personnel can be reduced; the negative-pressure device is used in the field of negative-pressure devices.

Description

technical field [0001] The invention relates to a negative pressure device, in particular to a negative pressure device with pressure display. Background technique [0002] There are many clinical situations that require the use of negative pressure devices for sampling and treatment, but negative pressure devices generally cannot judge the pressure inside the device with the naked eye, whether it is in a state of depressurization or excessive pressure. [0003] Due to the special application of the negative pressure device, the negative pressure of the device has a direct impact on the sampling volume and safety. Therefore, the negative pressure device needs to have the function of monitoring the pressure in the device or when the device is in use. [0004] Common negative pressure devices include vacuum blood collection tubes, negative pressure drainage devices, electric suction devices, etc., a small part of them are equipment, and most of them are disposable products. ...
