Abstract
The utility model discloses a respirator with collecting and sterilizing purifying apparatuses for exhalation, and belongs to the improved technology of respirators. Compared with the existing respirators, the respirator is provided with a collecting and sterilizing purifying apparatus. The utility model is characterized in that an air outlet of the respirator is provided with a one-way open and close diaphragm or a breathing valve of a tongue piece and a communicating tube; the terminal end of the communicating tube is connected with a collecting and sterilizing purifying processor composed of a draught fan and an electric heater; the outlet of the draught fan is connected to an adsorption cleaning filter element connected with the electric heater in parallel through a cross valve; the filter element is composed of desiccant, activated carbon and chemical disinfectant; the collecting and sterilizing purifying processor is connected to a remote transmitting monitor. The utility model has the advantages that various pathogens and harmful chemicals in the breathing air from the respirator can be effectively killed; the harmful substances can be prevented from dissipating into wards; the concentration of the pathogens in the air can be decreased; the repeated or cross infection among the patients can be relieved; the infected danger of the medical staff can be largely reduced.
Description
Technical field
This utility model relates to a kind of having and exhales the respirator of discharging collection and confinement of gases and sterilizing and purifying device, belongs to the improvement technology of respirator
Background technology
Existing respirator mainly is made up of suction assisting device and exhaustor.By respirator, patient's breath still is emitted on indoor.If patient is a patients with infectious diseases, discharge gas without exhaling of any sterilizing and purifying and can make unit volume pathogen density increase in the ward, this pollutes and increases patient's repetition or cross infection to ward, the medical worker is infected, particularly run into the stronger disease of infectiousness, its consequence is more serious.Surgery anesthesia also contains anesthetis with the discharge gas of respirator, direct emptying entail dangers to medical personnel, and cause environmental pollution.
Summary of the invention
The object of the present invention is to provide exhale the respirator of discharging collection and confinement of gases and sterilizing and purifying processing a kind of having.This respirator not only can help patient respiration, and can effectively kill multiple pathogen, and prevent the loss of pathogen to ward space, reduce the concentration of pathogen in the air, alleviate patient's repetition or cross infection, and can reduce the infected danger of medical personnel greatly.
This utility model is realized by following technical proposals, the respirator that configuration is collected on the basis of existing respirator, the sterilizing and purifying device is formed.It is characterized in that: have the unidirectional switching diaphragm of up and down perforate or the breather valve of tongue piece being provided with one with the respirator air vent, end in communicating pipe connects a collection and a sterilizing and purifying processor of being made up of blower fan and electric heater, the outlet of air-introduced machine connects an adsorption cleaning filter element in parallel with electric heater by a three-way valve, and this filter element is made up of desiccant, active carbon and chemosterilant.This is collected the virus killing purifying processor and connects a far-transfer monitor.
Above-mentioned watch-dog control circuit comprises safety protective circuit, voltage control circuit, heater breaking alarming circuit, temperature control display circuit and blower fan breaking alarming circuit composition.
Advantage of the present utility model is:
1. can both guarantee in all cases the normal pressure of discharging gas of exhaling that is rich in pathogen is effectively collected, and send into the high-temperature sterilization purifying processor that places isolation room outer, after high temperature virus killing purification or physical and chemical adsorption, enter atmosphere by quantitative blower fan.
2. can be used for the anesthesia deflated absorption cleaning of respirator.
3. because of the sterilizing and purifying processor can place outdoor application, avoided the temperature rise in the ward.Special-purpose distribution communicating valve also can be collected the malicious air of catching an illness of higher concentration around the patient in the lump and be displaced into outdoor sterilization, thereby cuts off pathophoresis approach in the ward.
4. can realize teletransmission monitoring and warning.

The specific embodiment
Based on existing various have wound or noninvasive ventilator, be provided with one at its breath air vent and have the breather valve of unidirectional switching diaphragm (or tongue piece) up and down, when bleeding distribution and accident during in order to the aerofluxus of maintenance respirator and atmospheric automatic switching on.End in communicating pipe connects a collection and a sterilizing and purifying processor of being made up of blower fan (air-introduced machine) and electric heater, is used to contain the processing of pathogenic raw-gas.The composite purification filter element is mainly used in the absorption cleaning that contains chemical substance in the anesthesia respirator aerofluxus.The duty of this collection virus killing purifying processor has a far-transfer monitor to be controlled.
Work process is: fan starting, be communicated with pipe end formation negative pressure, because fan delivery is much larger than the respirator expiratory gas volume, breather valve bottom air inlet diaphragm (or claiming the air distribution diaphragm) is opened, wind is mended in distribution in communicating pipe, leaking of the contamination gas of breathing out when preventing normal pressure, the unidirectional diaphragm in top that be communicated with atmosphere this moment is in closed condition because of the air inducing adhesive.When the air-introduced machine accident was cut off the power supply, bottom air inlet diaphragm was closed automatically, and the upper membrane sector-meeting exhales exhaust stream to open automatically with exhalation, made the straight-through atmosphere of breath to reduce the exhalation exhaust resistance, prevented the patient exhales difficulty, and watch-dog is reported to the police automatically simultaneously.
Claims (2)
1. one kind has the respirator of exhaling discharge collection and confinement of gases and sterilizing and purifying device, this respirator disposes collection on the basis of existing respirator, the sterilizing and purifying device, it is characterized in that: have the unidirectional switching diaphragm of up and down perforate or the breather valve of tongue piece being provided with one with the respirator air vent, end in communicating pipe connects a collection and a sterilizing and purifying processor of being made up of blower fan and electric heater, this is collected the virus killing purifying processor and connects a far-transfer monitor, the outlet of air-introduced machine connects an adsorption cleaning filter element in parallel with electric heater by a three-way valve, and this filter element is by desiccant, active carbon and chemosterilant are formed.
2. exhale the respirator of discharging collection and confinement of gases and sterilizing and purifying device described having by claim 1, it is characterized in that: the far-transfer monitor control circuit comprises by safety protective circuit, voltage control circuit, heater breaking alarming circuit, temperature control display circuit and blower fan breaking alarming circuit and forming.
