Pressing type body fluid aspirator

Abstract

A pressing type body fluid aspirator is mainly used for aspirating phlegm in the mouth of a patient when the critical patient is rescued and / or aspirating amniotic fluid in the mouth of an infant. The pressing type body fluid aspirator comprises a cylinder and an upper cover. The cylinder is a flat cylinder with the upper portion open, and the interior of the cylinder is divided into four independent small spaces which comprise a liquid storage cylinder, a primary purification cylinder, a secondary purification cylinder and a negative pressure generation cylinder from left to right. A sponge is placed at the bottom of the liquid storage cylinder. Flow dispersion plates are placed at the lower portion of the primary purification cylinder and the lower portion of the secondary purification cylinder, a layer of active carbon is placed on the flow dispersion plate in the primary purification cylinder, and disinfection liquid medicine is placed in the secondary purification cylinder. A piston rod is inserted into the negative pressure generation cylinder to be connected with a piston in a screwed mode, and a spring is installed below the piston. The pressing type body fluid aspirator has the advantages that operation is easier and faster and saves more labor, and through the two-stage filtration and disinfection of active carbon adsorption and the liquid medicine, most various microorganisms such as bacteria, viruses and allergens in peculiar smell gas of body fluid can be adsorbed, dissolved, killed and locked in the active carbon and the liquid medicine.

Description

technical field [0001] The invention relates to a medical suction device, in particular to a press-type body fluid suction device, which is mainly used for suctioning sputum in the patient's mouth or amniotic fluid in the baby's mouth. Background technique [0002] In hospitals, when medical personnel are rescuing critically ill patients, and when obstetricians and gynecologists deliver newborns, sometimes in order to rush for time, artificial sputum suction devices are usually used to suck sputum or amniotic fluid in the mouths of patients and babies. The advantage of the artificial sputum suction device is that it does not require a power source, is easy to carry, and is quick and convenient to use. The traditional artificial sputum suction device is composed of a sputum storage body, an upper cover, and two flexible tubes connected with the upper cover. The hose is inserted into the patient's mouth, and the end of the other hose is held in the mouth of the medical staff ...

AI Technical Summary

Problems solved by technology

Usually sputum or amniotic fluid has a peculiar smell, and these odorous gases contain sputum odor, bacteria, allergens, etc., and these gases with peculiar smells and germs are bound to be sucked into the mouth during the artificial inhalation process; If there is too much sputum or amniotic fluid in the sputum body, or if the sputum storage body is tilted, the sputum or amniotic fluid in the sputum storage body will be sucked into the mouth of the medical staff, causing vomiting and nausea of ​​the medical staff

This is unhygienic and will affect the normal work.

At present, there are still some sputum suction devices that use negative pressure balloons instead of people's mouths for suction, but the smelly smell is discharged into the room immediately, which not only pollutes the indoor air, but also affects the physical and mental health of medical staff.
