Simple sputum aspirator

Abstract

The invention relates to a simple sputum aspirator. A main body of the simple sputum aspirator comprises a negative pressure ball at the upper portion, a sputum storage device in the middle, a sputum aspiration tube at the lower portion and the like. The negative pressure ball is a device capable of generating aspiration negative pressure; the shape and the materials of the negative pressure ball are not limited; and a spring bringing convenience to resetting of the negative pressure ball can be arranged inside the negative pressure ball. The sputum storage device in the middle is a transparent container, scales are arranged on the wall, and therefore the nature and the collecting amount of collected sputum can be observed. A function cover is arranged at the upper end of the liquid storage device; and an air inlet one-way valve, an air outlet one-way valve, a backflow-prevention channel and the like are arranged on the function cover. The function cover is in tight connection with the negative pressure ball and the sputum storage device. Scales are arranged on the sputum aspiration tube at the lower portion, so that the insertion depth can be conveniently observed and judged. Aspiration heads at the front end are spherical aspiration heads, a plurality of long-strip-shaped aspiration holes or aspiration heads in other shapes. The back portion of the sputum aspiration tube is inserted into the sputum storage device, and a backflow-prevention one-way valve is arranged at the tail end of the sputum aspiration tube. The sputum aspiration tube can be sleeved with an umbrella-type protection cover, so that contamination of bucking objects to medical workers is avoided.

Description

Technical field [0001] The invention relates to a simple sputum suction device. Background technique [0002] After a newborn is born, amniotic fluid and sputum will adhere to the mouth and throat. In order to prevent asphyxia of the newborn, it is necessary to routinely attract the respiratory tract of the newborn in the delivery room or operating room. Existing sputum suction tools include a midwife mouth suction suction device, aspirator suction tube, ear suction ball, piston suction device, etc. The mouth suction sputum suction device requires medical staff to suck out the patient's sputum through the sputum suction tube with their mouths. This may cause the sputum to enter the mouth of the medical staff, posing health and safety risks. The sputum suction tube of the aspirator needs electric suction, and its negative pressure is not easy to control, and it is easy to cause neonatal respiratory mucosal damage. The ear-suction ball cannot be continuously sucked. It is directl...

AI Technical Summary

Problems solved by technology

Mouth-suction sputum suction device requires medical staff to use their mouths to suck out the patient's sputum through the suction tube, which may cause sputum to enter the mouth of medical staff, posing a health and safety hazard

The suction tube of the aspirator requires electric suction, the negative pressure is not easy to control, and it is easy to cause neonatal respiratory mucosal damage

The ear suction ball cannot be continuously sucked, and the sputum directly enters the negative pressure suction ball when it is directly used for sputum suction. After each suction operation, the sputum needs to be squeezed out first, and it is also extremely inconvenient to clean the negative pressure suction ball

Various types of piston suction devices have complex designs, some are too large to be carried easily, and are laborious to pull when not in use for a long time.
