Description
Technical field
The invention belongs to Medical Devices manufacturing field, is related to a kind of anesthesia machine system structure, and in particular to a kind of Anesthesia machine
Gas pressure alarm device.
Background technology
Anesthesia machine is clinically mainly used in suction-type anesthesia.Source of the gas used in Anesthesia machine mainly has oxygen, air and oxidation
Sub- nitrogen, oxygen is the most important gas for maintaining patient vitals in these three gases, therefore source of oxygen must remain enough
Air pressure, so Anesthesia machine requirement will have oxygen low-pressure alarming device.Current type of alarm has two kinds, i.e. electronic warning and pneumatic
Alarm.Electronic warning is typically to send alarm with loudspeaker, and sound is more melodious, but needs individually to set in anesthesia machine system
The circuit and part of correlation are put, the complexity of system is added, also improves cost.Pneumatic alarm requires that time of fire alarming is no less than
7 seconds；Current pneumatic alarm technology majority is to utilize gas used in anesthesiaing system, and gases at high pressure are stored by air accumulator,
During source of oxygen hypotony, the gases at high pressure in air accumulator directly blow a whistle, simple in construction, cost by a pin hole
It is low, but the sound tone frequency sent is very high, it is very ear-piercing, influence the work of medical personnel.
The content of the invention
It is an object of the invention to provide a kind of Anesthesia machine gas pressure alarm device, and current startup warning device is entered
Row improves, and when oxygen pressure is less than setting value, can send alarm melodious for a long time.
Technical scheme is as follows：
A kind of Anesthesia machine gas pressure alarm device, including source of oxygen, air accumulator, two position two-way valve, the source of oxygen are led to
Cross pipeline and draw two-way gas, be directly connected to the control valve port of two position two-way valve all the way, gas storage is connected by a check valve all the way
The air inlet of tank, the air inlet of the gas outlet connection two position two-way valve of air accumulator, it is characterised in that：The two position two-way valve goes out
Gas port connects an alarm, and the alarm includes the cylindrical shell that an inside is provided with cavity, the housing by upper shell and
Lower house clamping forms；One end of housing sets a pinhole nozzle, and the other end sets a cylindric pitch pipe, the pin in housing
It is a tubaeform gas mixing chamber between hole nozzle and pitch pipe, the wide mouth part of tubaeform gas mixing chamber is towards the tuning
Pipe, the thin mouth end of tubaeform gas mixing chamber connect described two towards the pinhole nozzle, the air inlet of the pinhole nozzle
The gas outlet of two-port valve.
The alarm of the present invention utilize venturi principle, and the gas of air accumulator by pin hole into being sprayed after warning device first
Mouth, due to venturi principle so that negative pressure is produced around jet expansion, so as to suck the air in air, these air and height
The low-pressure air current for forming big flow after gas mixing is pressed to send the relatively low also more melodious alarm of tone frequency by pitch pipe
Sound, and the gases at high pressure stored with the air accumulator of volume very little can make alarm send long-time alarm.
Brief description of the drawings
Fig. 1 is the structure principle chart of the present invention；
Fig. 2 is the alarm arrangement decomposing schematic representation of the present invention；
Fig. 3 is the alarm principle of sound figure of the present invention.
Embodiment
Such as Fig. 1, the present invention includes source of oxygen 1, air accumulator 2, two position two-way valve 3, and the source of oxygen 1 draws two by pipeline
Road gas, the control valve port of two position two-way valve 3 is directly connected to all the way, connect the air inlet of air accumulator 2 by a check valve 4 all the way
Mouthful, the air inlet of the gas outlet connection two position two-way valve 3 of air accumulator 2；The gas outlet of the two position two-way valve 3 connects an alarm
5。
As shown in Fig. 2 the alarm 5 includes the cylindrical shell that an inside is provided with cavity, the housing is by upper shell
51 and the clamping of lower house 52 form；One end of housing sets a pinhole nozzle 53, and the other end sets a cylindric tuning in housing
Pipe 54, it is a tubaeform gas mixing chamber 55 between the pinhole nozzle 53 and pitch pipe 54, tubaeform gas mixing chamber 55
Wide mouth part sprays towards the pitch pipe 54, the thin mouth end of tubaeform gas mixing chamber towards the pinhole nozzle 53, the pin hole
The air inlet of mouth 53 connects the gas outlet of the two position two-way valve.
When source of oxygen pressure is normal, the gas pressure that source of oxygen leads to two position two-way valve control valve port can make two two
Port valve is closed, and the air inlet of two position two-way valve can not connect with gas outlet；Source of oxygen enters gas storage by check valve
Tank, store high pressure oxygen.When source of oxygen is less than setup pressure value, two position two-way valve is in open mode, the height in air accumulator
Pressure oxygen enters alarm by bi-bit bi-pass valve air gate.
As shown in figure 3, after high pressure oxygen in air accumulator enters alarm, first by pinhole nozzle 53, subsequently into
Tubaeform gas mixing chamber 55, due to venturi principle so that negative pressure is produced around jet expansion, so as to suck the sky in air
The low-pressure air current of big flow is formed after gas, these air and high pressure oxygen mixing, low-pressure air current sends frequency by pitch pipe 54
Relatively low alarm.
