Double-air-bag tracheal foreign body extractor

Abstract

The invention discloses a double-air-bag tracheal foreign body extractor which comprises a hollow hose, an extraction air bag, a supporting air bag and a conical elastic soft head, wherein the extraction air bag, the supporting air bag and the conical elastic soft head are connected with the hollow hose. The longitudinal section of the extraction air bag is in a double-U shape, and the extraction air bag is made of materials which are good in elasticity and strength. The longitudinal section of the supporting air bag is in a shape like a Chinese character 'ao', and the supporting air bag is made of materials which are good in strength and poor in elasticity. The two air bags are connected with an inner cavity through air holes formed in the wall of the hollow hose encircled by the two air bags. The front end of the hollow hose is connected with the conical solid elastic head. The glottis is exposed through a laryngoscope, the extractor is coated with lubricating oil, when the conical elastic soft head is put into trachea and gradually put deep into the position close to the tracheal bifurcation, a moderate amount of gas is injected into the hollow hose through an injector until the hollow hose can be pulled out exactly, then the hollow hose is pulled out slowly until the hollow hose is close to the glottis, then the moderate amount of gas is injected again, the diameter of the front end of the hollow hose becomes small until the hollow hose can pass the glottis easily, the air bags are pulled out, and foreign bodies can be taken out. The double-air-bag tracheal foreign body extractor has the advantages of being convenient and fast to use, free of a bronchoscope, free of secondary injury and capable of taking out a plurality of small foreign bodies at a time.

Description

technical field [0001] The invention relates to a medical operation instrument. More specifically, the present invention relates to a medical operation instrument for removing tracheal foreign bodies. Background technique [0002] Foreign bodies in the trachea and bronchi are common emergencies in many clinical departments. Once a foreign body enters the trachea, it can be life-threatening. At present, the treatment of this kind of disease is mostly taken out with forceps under bronchoscope, but for large and fragile smooth (such as jelly), irregular foreign bodies (such as rice pieces), foreign bodies, tubular foreign bodies, etc., forceps can be used to remove these It is difficult to clamp the foreign body, and it is difficult to pass through the glottic fissure during the removal process. In clinical practice, the operation often fails due to the lack of special surgical instruments for removing these foreign bodies, and bronchoscopy is not popular at the grass-roots le...

At present, the treatment of this kind of disease is mostly taken out with forceps under bronchoscope, but the large and fragile smooth (such as jelly), irregular foreign bodies (such as rice pieces), foreign bodies, tubular foreign bodies, etc., the forceps can be used to remove these It is difficult to clamp the foreign body, and it is difficult to pass through the glottic fissure during the removal process. In clinical practice, the operation often fails due to the lack of special surgical instruments for removing these foreign bodies, and bronchoscopy is not popular at the grassroots level. Repeated hospital transfers delayed the precious rescue time and died
