Description
Technical field
The utility model relates to a kind of wall oxygen inhalators, vacuum extractor detection device.
Background technique
Oxygen inhalation apparatus is for medical institutions' first-aid patients oxygen supply and for a kind of inhalant medical treatment meter of anoxic patient's oxygen
Measuring device tool, vacuum extractor are applied in the devices such as paunch flusher, sputum aspirator, stream of people's machine and operation suction, by generating negative pressure shape
State squeezes the substance outside sucking head to sucking head, to complete the effect " attracted ".Above two measurement instrument is all to rob
Use when rescuing, perform the operation and treating is the conventional instrument of medical institutions at different levels, and the frequency used is very high, and pressure, flow are accurate
Degree directly influences the safety of patient.Therefore, oxygen inhalation apparatus and vacuum extractor need its accuracy of periodic detection, to ensure
Medical safety.
Currently, wall oxygen inhalator detects its pressure and flow parameter, vacuum extractor difference by special detection device
Negative pressure parameter is detected by its special detection device.When detecting at the scene, since two sets of detection device volumes are larger, not side is carried
Just, when especially detecting in ward, usual wall oxygen inhalator and vacuum extractor are placed adjacent, and are limited by field condition
System, influences detection efficiency.
Summary of the invention
In view of this, in order to solve the problems, such as that oxygen inhalation apparatus and vacuum extractor can be detected in same detection device,
The utility model provides a kind of wall oxygen inhalator, vacuum extractor detection device, which can easily be at one
It realizes on instrument to two kinds of detections by test examination instrument, realizes a device detection positive pressure, negative pressure and flow parameter.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
Gas circuit is sequentially connected automatic blocking air inlet, digital pressure detection instrument, L-type three-way ball valve normal open end；
The end L-type three-way ball valve a, proving flowmeter, wall oxygen inhalator interface are sequentially connected；
The end L-type three-way ball valve b is connect with negative pressure generator；
The negative pressure generator is connect with equilibrated valve, vacuum extractor interface respectively；
The equilibrated valve is communicated with the atmosphere；
The L-type three-way ball valve is placed in L-type three-way ball valve normal open end and the end L-type three-way ball valve a communicating position, at this time wall type
Oxygen inhalation apparatus detects gas circuit perforation, wall oxygen inhalator can be accessed wall oxygen inhalator interface and detected；
The L-type three-way ball valve is placed in L-type three-way ball valve normal open end and the end L-type three-way ball valve b communicating position, at this time negative pressure
Aspirator detects gas circuit perforation, vacuum extractor can be accessed vacuum extractor interface, be depressurized, examined by negative pressure generator
It surveys；After detection, equilibrated valve is opened, balances pressure, restores normal use.
The utility model has the beneficial effects that can realize on an instrument to wall oxygen inhalator, vacuum suction
The positive and negative pressure and flow parameter of device detect, small in size, easy to carry, and it is convenient to operate, and improve detection efficiency.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is connection schematic diagram described in the utility model.
