Abstract

The present invention discloses a respiration sterilizer which relates to a device for sterilizing gas exhaled from respiratory tract infectious patients. A mouth and nose cover (5) is arranged outside a box body (1); one end of a gas delivery pipe (6) is fixedly connected with the mouth and nose cover (5), and the other end is fixedly connected with a gas inlet end (16) of a blower (2); a gas outlet (17) of the blower (2) is connected with one end of a guide pipe (10), and the other end of the guide pipe (10) is arranged at the lower part of a liquid sterilizer (3) through the cover body (13) of the liquid sterilizer (3); the other end of a connecting pipe (9) is fixed on a gas inlet (18) of a filter (4). The present invention can sterilize the gas exhaled from respiratory tract infectious patients (comprising atypical pneumonia patients) so that the virus content in the sanitized gas is 0; the present invention is especially suitable for sterilization or prophylactic sterilization of the gas exhaled from patients, suspected patients or people who contact the patients and the suspected patients in close ranges; the present invention can decrease the virus infection probability to maximal degrees, optimize the living space of healthy people and greatly lower the expenses of environmental sterilization.

Description

Breathe disinfector

Technical field: the present invention relates to the device that a kind of gas that the respiratory infectious disease people is breathed out carries out disinfection.

Background technology: when respiratory infectious disease is popular, when particularly SARS virus is wreaked havoc, the submerged method of its blocking virus is except that exquisite Personal hygiene and to the environment disinfected, mainly be to prevent by wearing masks, yet the just invasion and attack of Passive Defence virus wear masks, can not initiatively reduce the existence of virus in the air, isolation to known patient, airborne virus can not be absolutely eliminated in sterilization to known patient bedroom or ward, wearing masks to patient influences the drainage of patient body's inner virus from respiratory tract, also be unfavorable for patient's rehabilitation, in the environment of patient's life, more much bigger than other place by the chance of viral infection.

Summary of the invention: the objective of the invention is to develop a kind of breathing disinfector, it can carry out disinfection the gas that the respiratory infectious disease people breathes out, make the gas inner virus content after the sterilization approach 0, be specially adapted to known patient and patient suspected or with the sterilization of people's breath of patient's close contact, can reduce the infection probability of virus to greatest extent, optimize healthy life space alive, can reduce the expense of environment disinfected greatly, have the advantages that volume is little, disinfection efficiency is high, the user breathing is smooth freely.The present invention comprises casing 1, pressure fan 2, at least one liquid steriliser 3, filter 4, oronasal mask 5, appendix 6, connecting leg 9, conduit 10, supply socket 15; Pressure fan 2, liquid steriliser 3 and filter 4 are fixed in the casing 1, oronasal mask 5 is arranged on the outside of casing 1, one end of appendix 6 is fixedlyed connected with oronasal mask 5, the other end of appendix 6 is fixedlyed connected with the inlet end 16 of pressure fan 2, an end of connecting duct 10 on the gas outlet 17 of pressure fan 2, the lid 13 of the other end of conduit 10 by liquid steriliser 3 is arranged on the bottom in the liquid steriliser 3, one end of connecting leg 9 is arranged on top in the liquid steriliser 3 by lid 13, the other end of connecting leg 9 is fixed on the air inlet 18 of filter 4, the sidewall 1-1 that the gas outlet 20 of filter 4 is fixed on casing 1 goes up and is exposed to casing 1 outside, the supply socket 15 of pressure fan 2 is fixed on the sidewall 1-1 of casing 1, active ash 11 is housed in the filter 4, disinfectant solution 19 is housed in the liquid steriliser 3.The present invention can carry out disinfection the gas that respiratory infectious disease people (comprising the severe acute respiratory syndrome patient) breathes out, make the gas inner virus content after the sterilization equal 0, be specially adapted to known patient, patient suspected or with the sterilization or the prophylactic disinfection of people's breath of these people's close contacts, can reduce the infection probability of virus to greatest extent, optimize healthy life space alive, greatly reduce the expense of environment disinfected, have that volume is little, disinfection efficiency is high, user breathes freely advantage smoothly.

Description of drawings: Fig. 1 is an overall structure sketch map of the present invention, and Fig. 2 is the structural representation of the specific embodiment two to the specific embodiment four, and Fig. 3 is the structural representation of the specific embodiment five.

The specific embodiment one: the (see figure 1) present embodiment is made up of casing 1, pressure fan 2, liquid steriliser 3, filter 4, oronasal mask 5, appendix 6, second liquid steriliser 7, second conduit 8, connecting leg 9, conduit 10, supply socket 15; Pressure fan 2 is fixed on the bottom righthand side in the casing 1, liquid steriliser 3 is fixed on the left side of pressure fan 2 in the casing 1, second liquid steriliser 7 is fixed on the lower-left end in the casing 1, filter 4 is fixed on the right side, middle part in the casing 1, oronasal mask 5 is arranged on the outside of casing 1, the external stability of oronasal mask 5 has air inlet filter bowl 5-1 and is connected with its inside, fixedly connected with oronasal mask 5 in the upper end of appendix 6, fixedly connected with the inlet end 16 of pressure fan 2 in the lower end of appendix 6, an end of connecting duct 10 on the gas outlet 17 of pressure fan 2, the lid 13 of the other end of conduit 10 by liquid steriliser 3 is arranged on the bottom in the liquid steriliser 3, one end of second conduit 8 is arranged on top in the liquid steriliser 3 by lid 13, the other end of second conduit 8 is arranged on bottom in second liquid steriliser 7 by the lid 12 on second liquid steriliser 7, one end of connecting leg 9 is arranged on top in second liquid steriliser 7 by lid 12, the other end of connecting leg 9 is fixed on the air inlet 18 of filter 4, the gas outlet 20 of filter 4 is fixed on the outside that the right side wall 1-1 of casing 1 went up and be exposed to casing 1, the supply socket 15 of pressure fan 2 is fixed on the bottom on the right side wall 1-1 of casing 1, activated carbon 11 is housed in the filter 4, in the liquid steriliser 3 and second liquid steriliser 7 disinfectant solution 19 is housed.Pressure fan 2 is universal motors.
