Abstract
An oxygen low-pressure alarm device of an anesthesia machine comprises an oxygen source. A gas conveying pipe of the oxygen source is connected with an oxygen storage tank through a one-way valve. The gas conveying pipe of the oxygen source is further connected with a two-position two-way pneumatic valve. The two-position two-way pneumatic valve is connected with a pneumatic alarm device through the gas conveying pipe. The pneumatic alarm device comprises a tubular shell body. A pinhole nozzle and a tuner are arranged in the tubular shell body. The pinhole nozzle is connected with the two-position two-way pneumatic valve through the gas conveying pipe.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of pneumatic warner, especially the oxygen low-pressure pneumatic alarm device in the anesthetic machine gas circuit.
Background technology
Anesthetic machine is mainly used in the suction-type surgery anesthesia clinically, its principle is to utilize the mist of oxygen or oxygen to make the anaesthetic volatilization by the anaesthetic vaporizer, produce oxygen and the mist of anaesthetic, will input to patient with the mist of anaesthetic, make patient be in narcotism.The used source of the gas of anesthetic machine mainly contains oxygen, air and nitrous oxide gas, and oxygen is the most important gas of keeping patients ' lives in these three kinds of gases, requires to keep certain pressure, so anesthetic machine requires to have the oxygen low pressure alarm.Normal employing is electronic alarm at present, but structure is complicated, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of oxygen low-pressure pneumatic alarm device, utilizes the oxygen in the anesthetic machine gas circuit to carry out pneumatic warning, and not only simple in structure, cost is low, and Melodious chimes of doom.
Structure of the present utility model is as follows:
A kind of anesthetic machine oxygen low-pressure alarming device, comprise source of oxygen, the appendix of source of oxygen is connected with air accumulator by check valve, it is characterized in that: the appendix of described source of oxygen also connects a bi-bit bi-pass pneumatic operated valve, and described bi-bit bi-pass pneumatic operated valve is connected with a pneumatic alarm by appendix again.
Described pneumatic alarm comprises a tubular shell, is provided with pinhole nozzle and variator in the tubular shell, and described pinhole nozzle is connected by appendix with described bi-bit bi-pass pneumatic operated valve.
Described tubular shell is provided with through hole.
This utility model directly utilizes the oxygen in the anesthetic machine gas circuit to carry out pneumatic warning, and when oxygen pressure was lower than setting value, the bi-bit bi-pass pneumatic operated valve was opened, oxygen enters alarm by the bi-bit bi-pass pneumatic operated valve, Melodious chimes of doom, and simple in structure, and cost is low.

The specific embodiment
As shown in Figure 1, this utility model comprises source of oxygen 1, and the appendix of source of oxygen is connected with air accumulator 3 by check valve 2; And the appendix of source of oxygen also connects a bi-bit bi-pass pneumatic operated valve 4, and described bi-bit bi-pass pneumatic operated valve 4 is connected with a pneumatic alarm 5 by appendix again.
As shown in Figure 2, described pneumatic alarm 5 comprises a tubular shell, and this tubular shell is comprised of upper shell 51 and lower house 52, is provided with pinhole nozzle 6 and variator 7 in the tubular shell.Described pinhole nozzle 6 is connected by appendix with bi-bit bi-pass pneumatic operated valve among Fig. 1.
Can be provided with through hole on the described tubular shell.
This utility model can be set the opening pressure of bi-bit bi-pass pneumatic operated valve.When the pressure of source of oxygen was lower than setting value, the bi-bit bi-pass pneumatic operated valve was opened, and the oxygen of source of oxygen enters alarm device by two position two-way valve.
As shown in Figure 3, after oxygen enters alarm, by pinhole nozzle 6 ejections, and produce negative pressure with air by (air flow as shown by the arrows in Figure 3) in the through hole suction casing on the tubular shell, the cavity in the tubular shell is equivalent to gas hybrid chamber 8, air amount is in gas hybrid chamber 8 and oxygen mix, mineralization pressure is low and air-flow that flow is high, thereby variator 7 is blowed, produce chimes of doom, and this chimes of doom is more melodious soft.
