Abstract
A disposable nasopharynx enclosure gasbag belonging to medical instruments for general anesthesia nasal endoscope operations includes a gasbag(1) adapted to human oral cavities, a guide duct(2) and a valve(3). Nasopharynx is enclosed by an inflated gasbag(1) oppressing soft palate from oral cavity to reduce fluid flowing into oral cavity and facilitating flushing and cleaning nasal cavity. The gasbag(1) is charged or discharged by a guide duct(2) far away from the operation field and provided with a simple structure and low cost.
Description
Technical field
This utility model relates to the medical apparatus and instruments of general anesthesia intranasal videoendoscopic surgery, relates in particular to disposable nasopharynx closed airbag.
Background technology
The operation of nose section is the maximum operation of quantity in present ear,nose ﹠ throat-head and neck surgical operation, because nasal cavity is identical by nasopharynx with the oral cavity, the crimson blood of surgery of nasal cavity and flushing sewage can flow into the oral cavity by nasopharynx, not only increase the difficulty in operation cleaning art chamber, mucus with the oral cavity during attraction also sucks nasal cavity, increase infection chance, the old blood that also has forms clot in the oral cavity, danger when increasing tube drawing, common way is to clog sliver before the art in the oral cavity at present, takes out because sliver is omitted easily after operation is finished; Sliver is sucked blood easily, and influence is to the judgement of operative hemorrhage, so be not ideal way.
The utility model content
The purpose of this utility model is to design the disposable apparatus that can seal nasopharynx part in a kind of operation, and this device should be safe, easy, disposable.
In order to realize above purpose, this utility model provides a kind of disposable nasopharynx closed airbag, is made up of air bag, conduit and valve, and wherein, the material of described air bag is a medical PVC flexible glue material, and air bag is the class sphere, and 130ml is arranged, 80ml, three kinds of specifications of 40ml.
From oral cavity compressing soft palate sealing nasopharynx part, flow into liquid, convenient flushing and the cleaning nasal cavity in oral cavity by above-mentioned air bag with minimizing.Simultaneously, air bag is inflated or venting away from art district conduit by one, simple structure, and cost is low.
Description of drawings
Below with reference to accompanying drawings this utility model is described, wherein:
Fig. 1 is the sketch map of disposable nasopharynx closed airbag;
Fig. 2 is the sketch map of the valve of the disposable nasopharynx closed airbag among Fig. 1.
The specific embodiment
As shown in Figure 1, disposable nasopharynx closed airbag is made up of air bag 1, conduit 2 and valve 3, and the material of air bag 1 is a medical PVC flexible glue material, nontoxic, plasticity is good, and softness is to the oral mucosa not damaged, air bag 1 is for being about 130ml, 80ml, the class spherical envelope of three kinds of specifications of 40ml can satisfy the patient's of all ages and classes section needs, the length of conduit 2 is 30cm, and diameter is 2mm.
As shown in Figure 2, an one-way valve 4 is arranged in the valve 3, valve 4 open gases enter air bag during inflation, and when not inflating, valve 4 is replied and closed, and air bag is air tight.
The following describes concrete working condition of the present utility model.
General anesthesia comes into force, after the tracheal intubation, the suitable big ballonet of unaerated is inserted the patient oral cavity, insert valve 3 with the 100ml syringe, the syringe front end presses off unidirectional elasticity valve 4, injecting an amount of air by conduit 2, is that air bag is full, the compressing soft palate, close nasopharynx part, after extracting syringe, elasticity valve 4 is replied and is closed, and air bag is air tight.The routine disinfection drape begins operation then.After operation was finished, with air in the syringe pump air bag, pressure diminished, and air bag is taken out in the air bag atrophy.
Claims (2)
