Description

Oral cavity air curtain isolator

Technical Field

The invention relates to a medical instrument, in particular to an oral air curtain isolator.

Background

Most of the consulting rooms have small area, more patients, large flow, insufficient ventilation and turbid air. Aerosol generated by a water gun and a dental drill of the medical instrument rotates at high speed pollutes air and objects in a consulting room, and blood, saliva, secretion and the like are adhered to the used instrument and medical garbage, so that the environment of the consulting room is easily polluted. These factors can cause pollution in the limited space of the oral outpatient department, and the air quality qualification rate of some oral hospitals for investigating the oral consulting room is only 61.4%. When a doctor does not know, in the process of oral diagnosis and treatment of a patient with respiratory diseases, pollutants splashed outwards from the oral cavity carry a large amount of pathogens and are dispersed in the air around the patient in the form of aerosol. Due to the close surgical procedure, the surgeon is exposed to contaminated air and risks of infection. Thus reducing the generation and splashing of droplets and particles, while enhancing personal protection is important to reduce the risk of viral transmission.

In view of the above problems, some researchers have proposed that the patient may rinse his mouth with a disinfectant solution (chlorhexidine in a certain concentration) to reduce the air pollution caused by the spray. But can not solve the problems of blood, particle splashing and the like generated in the operation process. Some protective measures for the process are added, such as an air purifier and the like, which have certain efficacy on purifying polluted air, but pollutants in the air environment between the oral cavity of a doctor and the doctor still cannot be absorbed in time. Personal protection of the doctor is enhanced, such as wearing disposable protective clothing, wearing disposable masks and the like, so that a part of pollutants can be prevented from entering the body through a respiratory tract. After contaminants such as small droplets carrying pathogens attached to surfaces such as protective clothing evaporate, the pathogens remain in the air and are potentially dangerous. If the protective garment is improperly handled, the doctor inadvertently touches the contaminated surface of the protective garment and the doctor is still at risk of being infected.

Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to the embodiments are included in the scope of the present invention.

The invention discloses an oral air curtain isolator, which is shown in figures 1-2 and comprises an opener 1, wherein an air channel 4 is drilled in the opener 1, an air flow pipeline is arranged in the air channel 4, one side of the air flow pipeline is arranged in a convex state to form a suction pipe placing opening, a suction pipe for strong suction equipment can be placed in the suction pipe placing opening, the suction pipe for strong suction equipment can be conveniently placed in the oral cavity, a pipeline interface is drilled on the outer wall of the opener 1, a hose 9 is connected in the pipeline interface, the hose 9 is communicated with the opener 1 through the pipeline interface, a jet slit 6 is drilled on the inner wall of the air flow channel 4, the jet slit 6 is communicated with the air flow channel 4 and can be connected to the device through the hose 9 and other means by utilizing external clean air, the air flow channel 4 and the jet slit 6 are arranged on the inner side of the device, and air can be emitted along the jet slit 6 in the, form the air curtain of circular shape closed oral cavity, block spouting the foam, the little drop that splashes, tiny granule etc. that the process produced diagnosing, for stronger operation process needs, can set up two jet gaps 6 in one side that air flow channel 4 is close to the oral cavity, jet gap 6 can have certain deflection angle, when the passageway is full of to gas, can form double-deck air curtain, is equipped with lip fender concave edge 5 and lip fender flange 8 along the circumferencial direction equipartition on the mouth gag 1.

Referring to fig. 1-2, be connected with main arc portion 7 on the mouth gag 1, main arc portion 7 includes right arc portion 2 and left arc portion 3, right arc portion 2 and left arc portion 3 all are the setting of semi-arc, right arc portion 2 is connected with left arc portion 3, right arc portion 2 and left arc portion 3 are the annular setting along the 1 circumferencial direction of mouth gag, right arc portion 2 and the setting of 3 surfaces of left arc portion are smooth curved surface, the patient wears this device when doing the operation, this device forms the clean air curtain between patient and doctor, the propagation route between the doctor-patient has been blocked, particulate matter and droplet etc. have been reduced and to the outside giving off of device.

Wherein, lip fender flange 8 is the setting of convex arc, lip fender concave edge 5 is the setting of concave arc, consider the travelling comfort of wearing, set up lip fender concave edge 5 and lip fender flange 8, can utilize upper lip and lower lip to fix the device to mouth department at the operation in-process, simultaneously can make the device closely real better with the people's face, contaminated air and the overwhelming majority of droplet can not get into the room air through the device, when operation in-process splash degree is too big, the wind speed of air curtain is adjusted to the accessible stops, compare with process and terminal safeguard means, this device is oral cavity from polluting the source and controlling promptly, cross infection's probability has been reduced, it is simple to have the model simultaneously, and is low in cost, easily advantage such as popularization.

When the device is used specifically, when the splashing degree of pollutants is small, an external clean air bottle is opened, the pressure is reduced, a flowmeter is used for regulating a small flow value, gas enters the gas flow channel 4 through the hose 9, a circular gas curtain is formed after the gas flow channel 4 is filled with the gas at a certain speed, the oral cavity is isolated from the external air environment, a surgical instrument passes through the gas curtain for operation, and polluted gas, small liquid drops and the like generated in the surgical process are blocked by the gas curtain; lip fender notch 5 and lip fender flange 8 that encircle lip a week seal the oral cavity in fixed mouth type, avoid droplet etc. to block direct discharge to the outside air through the air curtain, its operation flow is similar with the aforesaid when the pollutant degree of splashing is great, and its difference lies in transfer flow meter flow, and increase air curtain wind speed reinforcing air curtain blocks the effect and chooses for use double-deck air curtain device before the operation is carried out.
