Abstract
The utility models relates to closed-cycle automatic sterilization breathing machine, in particular designed for fighting against atypical pneumonia and solving the problems in the prior breathing machine(as the catheter for expiratory air is opened outward, the expiratory air from the patients discharges at random that brings infection of the medical staff and pollution of the ventilating environment of the wards). A filter is arranged on the expiratory loop; a discharge pipe for waste gas with the pressure limiting valve is arranged between the filter and the body of the breathing machine; a senor group for air density is arranged on the inspiratory loop and the expiratory loop; in addition, a manual respiratory hag and an atomizer in step with the inspiration are arranged on the inspiratory loop so as to realize closed cycle between the breathing machine and the patients. By isolating the expiratory air of the patients from the outside or discharging the air after sterilization, the surrounding people are prevented from being infected by the expiratory air from the patients. Meanwhile, the machine can operate by hand while the power is off and control the drug delivery by humidification and atomization. The utility model is not only applicable for fighting against, but also applicable for preventing and curing other infectious diseases.
Description
Technical field: this utility model relates to a kind of respirator.
Background technology: at present, employed respirator all is open in the fight against SARS, promptly because the expired gas conduit communicates with the external world, causes patient expired gas arbitrarily to discharge, and it is a large amount of viral that this just must cause in the air disperse, and causes personnel's infection on every side.In addition, when working, respirator has a power failure or when in treatment, needing the artificial respiration in any case, must be near the open manual artificial ventilator of the artificial a kind of expiration of replacing of patient's mouth, it is the low coverage operating process that handover operation and Artificial Control are breathed, and latter's time is longer, the toxic gas of these exhalation directly discharges in the inlet chamber and because the closely operation that equipment deficiency caused is the main cause that causes medical personnel to infect, the main cause that air directly ventilates and propagates to the outdoor crowd of being in the ward.
The utility model content:
Task of the present utility model is at the problems referred to above, a kind of circulating automatic sterilization respirator that closes is provided, this respirator can realize and patient between sealing and circulating, be isolated from the outside by expired gas patient, thus stop that expired gas owing to patient causes to personnel's infection on every side.By being concentrated to disinfect, breath cuts off the route of transmission effectively.
Technical solution of the present invention is: a kind ofly close circulating automatic sterilization respirator, suction loop and exhalation loop that it comprises respirator body, master controller and is attached thereto, it is characterized in that, be provided with cleaner in the exhalation loop, the exhaust emission tube that can be connected and have the pressure limiting valve with the extraneous gas decontamination duct is set between cleaner and body, in addition, be provided with gas concentration on loop and the exhalation loop and the flow transducer group is connected with the respirator master controller sucking.
The said cleaner in front is made up of carboloy dioxide canister and gas sterilizing filter; Its branch is set as the 2-4 group, and can switch by gang switch.
In addition, establish a manual breathing bag that has a manually-operated gate between loop and the breathing body sucking; And air-breathing synchronous humidification Adding chemicals atomizer can be set at the air bag rear portion, nebulizer is connected with the respirator master controller by holding wire synchronously.
Compared with prior art, the utlity model has following advantage:
(1) because the setting of cleaner, carboloy dioxide canister wherein and gas sterilizing filter have adopted technological means such as comprising chemical reaction heating disinfection, gas molecule filter and absorption, therefore patient's breath is purified, thereby pathogen and other harmful substances eliminating carbon dioxide wherein and live, and send purified gas back to bellows through expiratory valve and repeat to use next time.Have only oxygen, air and medicine to enter respiratory tract in the whole so in the ordinary course of things respiratory, and do not have breath to excrete, therefore, just cut off the breath source of infection that uses in the respirator process.When treatment need discharge breath the time, pressure limiting valve goalkeeper that can be by adjustable pressure it be discharged in the gas depoisoning discharge tube outdoor through being discharged into after disinfecting as required.
(2) because the setting of gas concentration sensor group, so just can at any time signals such as oxygen concentration, gas concentration lwevel, tidal volume and airway pressure be sent into the respirator master controller, so that make timely reaction, when airway pressure increases, master controller can give the alarm, and under unmanned guard's situation, can open the pressure limiting valve automatically, expired gas is passed out to waste gas from discharge pipe disinfect the position, guarantee that expired gas is not excessive.
(3) because of carboloy dioxide canister need be interrupted replacing, therefore carboloy dioxide canister and gas sterilizing filter are designed to more than two groups, and switch by gang switch, so just reduced the replacing number of times, also just reduced the excessive chance of expired gas naturally.In a word this utility model can stop prior art use the respirator patient expired gas caused to personnel's infection on every side.
(4) owing on the suction loop, be serially connected with manual breathing bag and air-breathing synchronous nebulizer, can finish by the related switch of opening the respirator master controller when needing atomizing, need not open air flue, can not carry out remote-controlled operation under the open airway, nebulizer is only in intake period atomizing work synchronously, the expiration phase stops, in whole respiratory, has only oxygen like this, air and medicine enter respiratory tract, the atomization gas breath that the expiration phase is not contained pathogen excretes, therefore, just stopped the expired gas of patient under these situations to personnel's infection on every side.
Description of drawings: Fig. 1 is the utility model structural representation.
The specific embodiment: as shown in the figure, its suction loop and exhalation loop of comprising respirator body, master controller and being attached thereto of this utility model, it is characterized in that, on exhalation loop 4, be provided with cleaner 5, the exhaust emission tube 6 that can be connected and have pressure limiting valve 7 with the gas depoisoning discharge tube of outside is set between cleaner 5 and body 1, in addition, be provided with gas concentration on loop 2 and the exhalation loop 4 and flow transducer group 8 is connected with respirator master controller 1a sucking.Simultaneously establish a manual breathing bag 2b who has a manually-operated gate 2a between the body 1 with breathing sucking loop 2, be provided with air-breathing synchronous nebulizer 2c in manual breathing bag 2b back, this nebulizer 2c is connected with respirator master controller 1a by holding wire.The said cleaner 5 in front is made up of carboloy dioxide canister 5a and gas sterilizing filter 5b, divides to be configured to 2 groups, can switch by gang switch 5c.
This utility model can be used for preventing and treating various spreading venereal diseasess, is particularly useful for the fight against SARS.
