Description

Sealed expectoration collector

Technical Field

The utility model relates to an keep apart medical instrument technical field, concretely relates to sealed expectoration collector.

Background

For patients in infected areas, the patients need to be isolated from each other in the inquiry, treatment and hospitalization processes to prevent cross infection.

Among them, for respiratory infectious disease patients, sputum is often required to be taken for assay, however, sputum is generally adhered to the throat and is often taken manually by medical staff or by patient expectoration. When the medical staff manually takes the sputum: opening the mouth of the patient after the patient needs to take off the mask; the medical staff stretches the cotton swab or the sputum taking device into the throat of the patient to take sputum; however, the mouth is directly towards medical staff, and the short-distance contact easily causes cross infection, and phlegm taking is easy to cause discomfort, vomit and other symptoms, and a large amount of spittle is splashed, so that the infection risk is increased. When a patient expectorates, airflow rapidly flows out due to coughing, a large amount of saliva splashes, and viruses are splashed in a large area. Even with a mask, the rapid airflow causes the mask to expand rapidly and viruses to splash in large quantities.

Based on the above drawbacks, it is necessary to provide a solution to overcome the above drawbacks.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a sealed expectoration collector realizes that patient oneself gets phlegm with regard to expectoration to sputum is got in whole process isolation, reduces expectoration disease and spreads the risk.

The technical scheme is as follows:

the sealed expectoration collector is characterized by comprising an oronasal mask which is integrally hollow and hemispherical; the mouth-nose mask is provided with a nasal airflow port and a sputum spitting port; the nasal airflow port is connected with an airflow pipe, one end of the airflow pipe, which is far away from the oronasal mask, is an air outlet end, and the air outlet end of the airflow pipe is covered with an isolation membrane cloth; the spitting port is connected with a detachable sputum receiving pipe.

Through the design, the mouth-nose cover, the airflow pipe and the sputum receiving pipe are all made of plastic materials. When a patient needs to take sputum, the patient wears the oronasal mask to make the nasal airflow port aligned with the nostril, and presses the oronasal mask to make the face sealed with the oronasal mask to start expectoration; as the sputum enters the oral cavity, the patient collects the sputum after the sputum protrudes through the sputum discharging port, and the patient takes down the sputum connecting pipe to carry out laboratory examination for medical staff. Effectively prevent spittle from splashing at will and reduce the risk of cross infection of diseases.

According to a further technical scheme, in order to enhance the sealing performance between the face and the oronasal mask, a circle of rubber sealing ring is arranged at the edge of the oronasal mask.

According to a further technical scheme, the isolation film cloth is fixed on the air outlet end of the airflow pipe through a buckle.

By adopting the scheme, the whole collector can be repeatedly used, the isolation membrane cloth can be replaced and installed, and the oral-nasal mask is made of plastic materials and can be used for replacing the oral-nasal mask

According to a further technical scheme, in the transportation process, in order to prevent sputum from being poured out, an anti-pouring platform is protruded in the middle of the inner wall of the sputum receiving pipe, and the anti-pouring platform and the sputum receiving pipe are integrally formed.

According to a further technical scheme, the anti-falling platform is formed by surrounding a blocking surface, a sputum collecting surface and a covering surface; the covering surface covers the inner wall of the sputum-receiving pipe and is columnar as a whole; the blocking surface of the anti-falling platform is annular as a whole and is vertical to the inner wall of the sputum-receiving tube; the sputum collecting surface is horn-shaped; the sputum collecting surface extends from one bottom edge of the covering surface to the other bottom edge of the covering surface, and the distance from the sputum collecting surface to the covering surface is gradually increased; one bottom edge of the covering surface is connected with the outer edge of the blocking surface, the other bottom edge of the covering surface is connected with the sputum collecting surface collecting inlet edge, and the sputum collecting surface collecting outlet edge is connected with the inner edge of the blocking surface.

Adopt above-mentioned ingenious project organization, when collecting the sputum, the sputum can be along with the sputum collection face from connecing the phlegm pipe mouth of pipe slip tub bottom, prevents down the platform and can effectively prevent the sputum outflow, can also prevent that viscidity mucus from evenly adhering at the inside pipe wall completely, is unfavorable for getting the phlegm from connecing the phlegm pipe.

In a further technical scheme, the sputum receiving pipe is connected with the sputum discharging port through threads. The sealing effect is good, the disassembly is convenient, and the sealing can be realized through the pipe cover after the disassembly.

According to a further technical scheme, the airflow pipe is a vertical bent pipe. Adopt the design of buckling, increase the air current and hinder, can block a part of saliva and leave at the pipe wall, reduce the saliva volume of discharging from the air current pipe.

The utility model has the advantages that:

the design is ingenious, and the structure is simple. Reduce the amount of saliva discharged from the airflow tube and reduce the risk of cross infection of diseases.
