Abstract

The utility model discloses a respirator for infectious respiratory disease patients, including an air inlet, an air outlet and a mask; wherein, the air inlet and the air outlet all connect to the mask to form a chamber; the inlet of the air inlet and the outlet of the air outlet are all provided with a one-way air current control element to ensure the air enters from the air inlet and goes out from the air outlet. The utility model diverts the air exhaled by patients with infectious respiratory disease into a detoxification device by means of the air inlet and outlet, rather than discharges into the ambient air, which effectively protects the personnel around patients, in particular the health of medical workers.

Description

Infectiousness respiratory system disease patient respiratory device

Technical field

This utility model relates to a kind of breathing equipment, particularly a kind of infectiousness respiratory system disease patient respiratory device.

Background technology

SARS (Severe Acute Respiratory Syndrome), Severe Acute Respiratory Syndrome, english abbreviation is SARS, is a kind of very dangerous infectious disease that comes into vogue in November, 2002, has intensive infectiousness at the very start.

In the process that respiratory system disease clinical diagnosis is in the past treated, because patient expired gas does not generally have infectiousness, can not cause virus on the medical staff infection, so breathing equipment is not generally drawn expiration, but order is exhaled and directly to be discharged into around patient's face and in the air in ward.But because the very big infectiousness of SARS virus, in therapeutic process to SARS patient, if patient's expiration directly is discharged in the air in ward, medical worker's infection probability will be increased greatly, especially in to the operation of therapeutic such as severe case's tracheal intubation and last respirator, dangerous just bigger.

If patient's SARS expiration can be drawn from breathing equipment, after some special disinfectant solution sterilization, be discharged into again in the air, just no longer have infectiousness, just can be good at containing the propagation of virus, the protection medical worker's is healthy.

The utility model content

Technical problem to be solved in the utility model provides a kind of human body respiration device; it not only has unidirectional air inlet; also has unidirectional gas outlet; can be with the patient expired gas of suffering from the infectiousness respiratory system disease by the gas outlet decontaminating apparatus that leads; and directly be not discharged in the air; effectively healthy personnel, the especially medical worker's around the protection patient is healthy.

This utility model breathing equipment mainly comprises air inlet, gas outlet and face shield.Air inlet and gas outlet all communicate with face shield, cavity of three's intermediate formation.

The bore of this utility model air inlet and gas outlet is standard size, is used for and the connection of medical airway.The inlet port end and the gas outlet port of export all have the one-way gas flow control assembly, make the air inlet can only air inlet, can not give vent to anger, and can only give vent to anger in the gas outlet, can not air inlet.When patient inhales, the clean gas that suction imports from air inlet, the gas outlet can't air inlet, when patient exhales, expiration is discharged by the gas outlet, imports decontaminating apparatus by conduit, can't pass through air inlet, so just make the not contaminated gas of resorb of patient, the people around more making is not infected by patient's expiration.This utility model disinfection trough is equally applicable to healthy personnel and suspected case, when healthy personnel use, allow the gas of process decontaminating apparatus feed air inlet, avoided direct suction may have the air of virus like this, when suspected case is used, air inlet all is connected decontaminating apparatus with the gas outlet, can prevent to be had the aerial infection of virus, can prevent that also the expiration that may have virus directly is discharged in the air.

The specific embodiment

Embodiment 1:

As shown in Figure 1, breathing equipment mainly is made up of air inlet 1, gas outlet 2 and face shield 3, and air inlet 1 and gas outlet 2 all communicate with face shield 3, cavity of three's intermediate formation.

The bore of air inlet 1 and gas outlet 2 is standard size, is used for and the connection of medical airway.Air inlet 1 arrival end and gas outlet 2 ports of export all have unidirectional flap valve 4, make the air inlet 1 can only air inlet, can not give vent to anger, and can only give vent to anger in gas outlet 2, can not air inlet.When patient inhales, the clean gas that suction imports from air inlet 1, gas outlet 2 can't air inlet, when patient exhales, exhale and discharge, import decontaminating apparatus, can't pass through air inlet 1 by conduit by gas outlet 2, so just make the not contaminated gas of resorb of patient, the people around more making is not infected by patient's expiration.

Embodiment 2:

As shown in Figure 2, be existing a kind of breathing equipment, gas outlet 2 is the annulus elastic tape, air inlet 1 unidirectional air inlet is exhaled and is utilized the air pressure of self to go out gas outlet 2, and this expiration is sporadic very strong, if do not controlled, people is on every side just very easily infected in the expiration that has virus.

As shown in Figure 3, be improvement to breathing equipment shown in Figure 2.Tightly be enclosed within on the gas outlet 2 with the rubber pocket 5 that has the airway interface, tied tight in the contact site, unnecessary rubber is tightened, and the patient expired gas that comes just can be by the specific decontaminating apparatus of airway importing that links with gas outlet 2, and can directly not be discharged in the surrounding air.

Embodiment 3:

As shown in Figure 4, be existing a kind of breathing equipment, gas outlet 2 is the opening on the round plastic shell, air inlet 1 unidirectional air inlet is exhaled and is utilized the air pressure of self to go out gas outlet 2, and this expiration is sporadic very strong, if do not controlled, people is on every side just very easily infected in the expiration that has virus.

As shown in Figure 5, be improvement to breathing equipment shown in Figure 4.Bind round on the round plastic shell with juvenile's face shield 6, because size is mated just, so the edge can not leak gas, according to practical situation, also can be on plastic housing with other dome hoop that has the airway interface, the patient expired like this gas that comes just can be by the specific decontaminating apparatus of airway importing that links with gas outlet 2, and can directly not be discharged in the surrounding air.

Embodiment 4:

As shown in Figure 6, it is existing a kind of breathing equipment, gas outlet 2 is several sulculuses that certain inclination is arranged on the cavity inner wall, because the gas pressure that air inlet 1 is come in is very big, gas outlet 2 has certain guidance quality again, exhales and can not go out from air inlet 1, only may be 2 discharge along the gas outlet, this expiration is sporadic very strong, if do not controlled, people is on every side just very easily infected in the expiration that has virus.

As shown in Figure 7, be improvement to breathing equipment shown in Figure 6.Tightly be enclosed within on the gas outlet 2 with the rubber pocket 5 that has the airway interface, tied tight in the contact site, unnecessary rubber is tightened, and the patient expired gas that comes just can be by the specific decontaminating apparatus of airway importing that links with gas outlet 2, and can directly not be discharged in the surrounding air.

Embodiment 5:

As shown in Figure 8, be further improvement to embodiment 2 breathing equipments.On air inlet 2, connect an air inlet capsule 7, when air inlet air pressure is not high, can make the patient have enough oxygen to supply with like this.When the patient exhaled, a certain amount of oxygen entered air inlet capsule 7 deposit, and when the patient was air-breathing, airway is supplied with oxygen part just can lay in part supply in 7 li in air inlet capsule when exhaling.
