Description
Technical Field
The invention belongs to the technical field of medical treatment, and particularly relates to a suction device for displaying a negative pressure numerical value.
Background
The negative pressure suction device is one of important medical equipment necessary for various clinical departments, and is particularly common rescue equipment in operating rooms, emergency departments and intensive care units. It utilizes the vacuum working principle to produce negative pressure in the cavity body so as to guide out the sputum, other related blood and other liquids of the lung of the patient and achieve the purpose of drainage.
The existing negative pressure suction device mostly adopts a dial indicator display device, the negative pressure value can not be quickly and accurately adjusted, the accurate reading value can not be displayed, an adjusting knob is not easy to loosen and not accurate, the tightness of the device is not good, and the pressure value is not stable. Different negative pressure values with different suction requirements exist, the existing negative pressure suction device is difficult to accurately adjust and quickly reach the requirements so as to save time, so that a negative pressure suction device which is convenient to adjust and display and is started by one key is urgently needed.
Disclosure of Invention
In view of the above deficiencies of the prior art, the present invention is directed to a vacuum suction device with a negative pressure display to solve the problems of the prior art.
In order to solve the technical problems, the invention adopts the technical scheme that: a suction device for displaying a negative pressure numerical value comprises a pneumatic pressure pump, wherein the pneumatic pressure pump is connected with a sealed container through a branch pipe; detecting a negative pressure numerical value display and adjustment device of the sealed container, wherein the negative pressure numerical value display and adjustment device is connected with a pneumatic pressure pump through a control processor; and a cut-off switch mounted to the other branch pipe; the sealed container consists of a cylinder body, an O-shaped sealing ring and a cover. The negative pressure numerical value display and adjustment device is provided with an adjustment button and a pressure display screen. The cover of the sealed container is in threaded connection with the branch pipe, and the negative pressure numerical value display and adjustment device is in threaded connection with the cover of the sealed container.
The utility model has the advantages that: the utility model achieves the purpose of pressure regulation through the negative pressure numerical value display and regulation device and the control processor; the negative pressure value display and adjustment device can accurately measure and display the negative pressure value and adjust the pressure value through the adjusting button; the negative pressure value display and adjustment device can set the negative pressure value by one key and can memorize the pressure value so as to be convenient for the next key starting to reach the memorized pressure value. The pressure value measured by the negative pressure numerical value display and adjustment device is analyzed and processed by the control processor and fed back to the pneumatic pressure pump, and the pressure pumping and pressure relief of the pneumatic pressure pump are controlled to achieve the specified pressure value and stabilize the pressure. The cylinder body and the cover of the sealed container are sealed by an O-shaped sealing ring, so that the sealing performance of the sealed container is better. The device realizes the connection of the branch pipe, the negative pressure numerical value display and adjusting device and the sealed container by using a threaded connection mode, and the threaded connection has good sealing property and detachability, so that the negative pressure value is prevented from being unstable, and the reliability and operability of the connection are improved.
