Abstract
An automatic switching device applied in air supply for patients belongs to the technical field of medical apparatus. The utility model is characterized in that one input of an air-oxygen mixing device is connected with the output of an oxygen bottle, the other input of the device is connected with the main end of a two-position three-way valve controlled by a pressure controller, the two switching ends of the device are respectively connected with the output of a central air supply and the output of an air compressor, the output of the air-oxygen mixing device is connected with the input of a breathing machine, and the output of the breathing machine is connected with the nose or the mouth of a patient. The pressure controller is communicated with the air compressor by a gating valve when the pressure of the central air supply is low. The utility model has the beneficial effects that when the central air supply can not normally supply air, namely when the pressure is below the pressure of normal air supply, the pressure controller can automatically switch and is communicated with the air compressor to guarantee the continuous running of the breathing machine, which eliminates the worry of patients and doctors, and the utility model provides technical assurance for widely utilizing the central air supply.
Description
Technical field
Belong to technical field of medical instruments.
Background technology
General medical breathing machine all has mini air compressor provides source of the gas for respirator, and along with the development and the renewal of the equipment of hospital, various big hospital has all been equipped central gas-supply (compressed air) system.The light duty compressor of central gas-supply system has many good qualities, and is convenient as saving the energy, compressor-free noise and maintaining.Consider respirator particularity in use, several months a few days 24 continuous throughout the twenty-four hour24, be necessary at central gas-supply as main source of the gas, when ensuring respiration the machine operate as normal, light duty compressor is source of the gas in support, at central air supply system normally under the situation of air feed, for respirator provides the work source of the gas.Present homemade small-sized air compressor does not all have automatic switching control equipment, in case central gas-supply break down, must manual switching to small-sized air compressor, for the generation of various accidents has stayed hidden danger.
Summary of the invention
In case this utility model provides central gas-supply to break down, also can connect the automatic switching control equipment of a kind of patient's of being used for air feed of another source of the gas air feed automatically.
The technical scheme that this utility model is taked is:
A kind of automatic switching control equipment that is used for patient's air feed, comprise respirator and oxygen cylinder, its scheme is: air and oxygen mix device, an one input and oxygen cylinder outfan join, total end of the two-position three way breather valve of another input and pressure controller control joins, and its other two change-over terminal are joined with central gas-supply outfan and air compressor outfan respectively; Air and oxygen mix device output termination respirator input, respirator output termination patient's nose or mouth.Described pressure controller is that sluice valve communicates with air compressor when central air feed forces down in definite value, and described definite value is for adjustable in the 1MP-0.1MP scope.
The beneficial effects of the utility model are:
When center air feed during at normal air feed, promptly be lower than normal air feed, pressure controller can automatically switch to air compressor and communicate, and guarantees the continual continuous operation of breathing function, remove patient and doctor's trouble and worry, provide technical guarantee for using central gas-supply on a large scale.
Description of drawings
Fig. 1 is this utility model gas circuit structure sketch map;
The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings
A kind of automatic switching control equipment that is used for patient's air feed, comprise respirator 7 and oxygen cylinder 5, its formation is: air and oxygen mix device 6, an one input and oxygen cylinder 5 outfans join, another input joins with total end 4-2 of the two-position three way breather valve 4 of controller 3 controls that are stressed, it is two change-over terminal 4-1 in addition, and 4-3 joins with central gas-supply 1 outfan and air compressor 2 outfans respectively; Air and oxygen mix device 6 output termination respirators 7 inputs, respirator output termination patient's nose or mouth 8.Described pressure controller 3 is sluice valve 4-2 when central air feed forces down in definite value, and 4-3 communicates; Described definite value is adjustable in the 1MP-0.1MP scope.
Claims (2)
