Abstract
The utility model discloses a kind of respirator air inlet gas circuit circuit board, this gas circuit circuit board is provided with the gas circuit integrated unit be made up of the ventilation air flue of the interface and connection interface that are connected and installed gas-tpe fitting and valve member.In use, only source of the gas need be connected up with respirator connection tube and just can, without the need to connecting each valve member piece by piece again, simultaneously, because interface channel is laid in circuit board inside, avoid the Leakage Gas problem of pipe fitting junction, dramatically reduce the workload of producing installation personnel, decrease the rate of breakdown of the armarium caused because of factors such as pipeline connection error or leakages.
Description
Technical field
This utility model relates to medical equipment parts technique with the apparatus field, is a kind of respirator air inlet gas circuit circuit board specifically.
Background technology
Respirator is a kind of conventional armarium.The gas that respirator is supplied to patient respiration is empty oxygen gas mixture, the source of the gas used is pressure-air and high pressure oxygen, pressure-air and high pressure oxygen all need to control through metre filter, pressure transducer detection, pressure-limiting safety valve pressure limiting, pressure maintaining valve voltage stabilizing and three-way magnetic valve, again through the mixing of empty oxygen mixer, could carry out for respirator.These controls and process valve member one pieces are coupled together and needs labor intensive and time, increase the workload of producing installation personnel person, meanwhile, because junction point is too much, be easy at jointing place generation leakage problem.
Summary of the invention
The purpose of this utility model is for current Problems existing, provides a kind of respirator air inlet gas circuit circuit board.
The purpose of this utility model is achieved through the following technical solutions:
A kind of respirator air inlet gas circuit circuit board, this gas circuit circuit board is provided with the gas circuit integrated unit be made up of the ventilation air flue of the interface and connection interface that are connected and installed gas-tpe fitting and valve member, the formation of described gas circuit integrated unit is: described interface comprises air inlet pipe interface, escape pipe interface, one-way ventilating interface tube, pressure sensor interface, pressure limiting valve interface, pressure maintaining valve interface and three-way magnetic valve interface, air inlet pipe interface and described pressure sensor interface, the air inlet of pressure limiting valve interface and pressure maintaining valve interface is communicated with, the gas outlet of pressure maintaining valve interface is communicated with the air inlet of three-way magnetic valve interface, 2 gas outlets of three-way magnetic valve interface are communicated with escape pipe interface and one-way ventilating interface tube respectively.
Further in scheme, described gas circuit integrated unit has 2, shares an one-way ventilating interface tube.Source of the gas needed for respirator is pressure-air and high pressure oxygen two kinds of sources of the gas, although use single gas circuit integrated unit passable respectively, and, be laid in by two gas circuit integrated units and more improve integrated level together, using also can be more convenient.
Further, gas circuit circuit board can be fixed on respirator or relevant position near respirator, described gas circuit circuit board to be also provided with fixing installing hole is installed.
This utility model has following outstanding beneficial effect:
Respirator air inlet gas circuit circuit board of the present utility model provides a kind of circuit board that the valve member connected needed for respirator air inlet can be integrated and connected together, only need each valve member be installed on corresponding connector, in use, only source of the gas need be connected up with respirator connection tube and just can, without the need to connecting each valve member piece by piece again, simultaneously, because interface channel is laid in circuit board inside, avoid the Leakage Gas problem of pipe fitting junction, dramatically reduce the workload of producing installation personnel, decrease the rate of breakdown of the armarium caused because of factors such as pipeline connection error or leakages.
