Description
Technical field
The present invention relates to technical field of medical equipment, particularly relate to a kind of source of the gas input processing integrated for the height of anesthetic machine and volume control device.
Background technology
In existing anesthetic machine, the detection control that source of the gas front end high input processing and rear end low pressure export by the module of following several dispersion by joint and hose connection rear realization: 1) air source inlet module, wherein each one of oxygen, laughing gas and air; 2) pipeline source of the gas pressure detecting module; 3) pressure regulator valve module, wherein each one of the air source inlet of corresponding oxygen, laughing gas and air; 4) electronic flowmeter module, each one piece of corresponding oxygen, laughing gas and air.Each module, by flexible pipe and fittings, forms a detecting and controlling system.
There is following defect in existing this kind of detecting and controlling system:
1, air source inlet module disperses independence separately, and being communicated with other module needs to assemble various terminal, and assembling, debugging and maintenance are inconvenient and time-consuming; Laughing gas and air two-way cannot share backend gas passage, and Material Cost is high.
2, pipeline source of the gas pressure detecting module is by the fittings of flexible pipe and air source inlet module, patch flexible pipe to waste time and energy, many hose connection wrong risk, and has risk of leakage under high pressure, two module dispersions are independent, make troubles to combined debugging, replacing and maintenance.
3, pressure regulator valve module is by the fittings of flexible pipe and air source inlet module, simultaneously by the fittings of flexible pipe and electronic flowmeter module, flexible pipe is more, there is wrong risk equally, there is risk of leakage under high pressure, make troubles to combined debugging, replacing and maintenance.
4, electronic flowmeter module three road gas is independent, is communicated with needs to assemble various terminal with other module, and assembling, debugging and maintenance are inconvenient and time-consuming; In addition, the output gas pressure of electronic flowmeter is without detection.Laughing gas and air two-way could not common gas passages, and Material Cost is high.
5, because the dispersion of each module is independent, ventilation joint test occupied ground is large, and Connection Step is loaded down with trivial details, also needs to break flexible pipe and refill and be fitted on complete machine after test passes.Every root flexible pipe and each joint are potential leakage points, and leakage point is many, if there is leakage, find leakage point quite difficult, and system stability and reliability do not ensure.
6, each module dispersion is independent, and mutually with hose connection, flexible pipe quantity is more, easily occurs wrong and leakage problem; During debugging maintenance, very chaotic after flexible pipe dismounting, the very complicated very easily wrong of recovery operation.
7, gas exports and is completed by hose connection, and ease for use is poor, and specialty requires high, and require higher to attendant, maintenance efficiency is too low, and maintenance cost is high.
