Abstract
The utility model discloses a disposable eustachian tube inflator which comprises a rhinobyon head, a soft catheter, a snake-shaped connector and an elastic connector; the air inlet of the rhinobyon head is connected with one end of the soft catheter, and the other end thereof is connected with an air outlet of the snake-shaped connector; the air inlet of the snake-shaped connector is connected with the elastic connector; and the other end of the elastic connector is connected with an airbag. The disposable eustachian tube inflator effectively prevents the cross infection of patients, more facilitates the operation of the medical personnel, has simple structure, has low cost, and is applicable to general hospitals and other places.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically is a kind of pharyngotympanic tube catheterization device that once uses.
Background technology
The pharyngotympanic tube catheterization device is the medical assistance apparatus of diseases such as a kind of novel treatment otopathy, influenza, and clinical practice now is comparatively general.What at present most of clinically medical workers adopted is the pharyngotympanic tube catheterization apparatus of homemade metal nose chock plug formula, because cost of manufacture is higher and this device durability height, so the medical worker can reuse the pharyngotympanic tube catheterization device.There are following two deficiencies in this device; The one, owing to make the easy cross infection of patient, the 2nd, because the short therefore medical worker of pharyngotympanic tube self length operates very inconvenient.
The utility model content
The purpose of this utility model is to solve above-mentioned existence deficiency, and a kind of easy to operate, disposable use pharyngotympanic tube catheterization device that can effectively prevent patient's cross infection is provided.
The technical solution of the utility model is: disposable use pharyngotympanic tube catheterization device, form by nasal obstruction head, flexible catheter, Serpentis type joint and elastomeric joint, it is characterized in that: a described nasal obstruction inlet end is connected with flexible catheter one end, the other end of flexible catheter is connected with the gas outlet of snakelike joint, the air inlet of snakelike joint is connected with elastomeric joint, and the other end of elastomeric joint is connected with air bag.
By disposable use pharyngotympanic tube catheterization device provided by the utility model, the center of wherein said nasal obstruction head and elastomeric joint all is provided with through hole; Described nasal obstruction head is strawberry shape.
This utility model is that the first end plug of the nasal obstruction of this device is gone into patient's nostril, and clearance seal around the nostril blows pharyngotympanic tube open with the gas pressure in the air bag, then to reach the purpose of diseases such as auxiliary treatment otopathy, influenza.The disposable use of this utility model, with after disappear and ruin, avoided patient's cross infection.Comfort when it adopts the nasal obstruction head increase of ergonomic designs to fill in, softish conduit has made things convenient for medical worker's operation, and elastomeric joint makes itself and being connected of source of the gas become more convenient, and is reliable, and it is simple in structure, and use in places such as suitable vast hospital with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below with reference to accompanying drawing the technical solution of the utility model is described further.
Fig. 1 is the structural representation of disposable use pharyngotympanic tube catheterization device, this utility model is made up of the nasal obstruction of strawberry shape 1, flexible catheter 2, Serpentis type joint 3 and elastomeric joint 4, described nasal obstruction 1 center is provided with through hole, the inlet end of nasal obstruction 1 is connected with flexible catheter 2 one ends, the other end of flexible catheter 2 is connected with the gas outlet of snakelike joint 3, the air inlet of snakelike joint 3 is connected with elastomeric joint 4, and the other end of elastomeric joint 4 is connected with air bag, and wherein elastomeric joint 4 centers are provided with through hole.
The whole parts of this utility model adopt non-toxic high molecular material production, and the principle design of nasal obstruction 1 an employing ergonomics feels comfortable when making it fill in the patient nostril as far as possible; Flexible catheter 2 adopts softish pvc pipe; Elastomeric joint 4 adopts the high resiliency latex, is convenient to the quick grafting of source of the gas and plays good sealing function.To have a stuffy nose during use and 1 fill in the patient nostril, make clearance seal around the nostril, a suitable air bag (generally adopting blowing up a balloon of sphygomanometer adapted) is inflated nasal cavity on elastomeric joint 4 terminations then, when reaching certain air pressure, just the pharyngotympanic tube of cutting out can blow open, make nasal cavity and the conducting of ear chamber, to reach the purpose of treatment disease.
