In above-mentioned soft passage nasopharynx part suction catheter, described sucking head is the spheroid of inner hollow, its ellipsoid evenly has some attraction apertures.The smog that multiple attraction aperture is beneficial to flushing liquor, blood and operation technique produce fully attracts.
In above-mentioned soft passage nasopharynx part suction catheter, described flexible pipe afterbody expands and negative pressure adjustment hole is opened in expanding place.Be beneficial to medical worker's pressing, simple to operate, easy to use.
In above-mentioned soft passage nasopharynx part suction catheter, described negative pressure adjustment hole is provided with antifouling and forms communication port between antifouling and negative pressure adjustment hole.Avoid flushing liquor, blood etc. directly and the finger contact of medical worker.
In above-mentioned soft passage nasopharynx part suction catheter, the described little tail end of negative pressure adjustment hole head end is large.Be beneficial to medical worker's pressing, simple to operate, easy to use.
In above-mentioned soft passage nasopharynx part suction catheter, the path length ecto-entad of described attraction aperture successively decreases successively and forms the little infundibulate of outer imperial palace.Prevent from excessive object from attracteding to flexible pipe to result in blockage.
In above-mentioned soft passage nasopharynx part suction catheter, described sucking head is made up of the metal material being applicable to human body, described metal material comprise in rustless steel, cobalt-base alloys and titanium-base alloy any one.Sucking head is made up of metal material, be beneficial to it and utilize self gravitation to carry out anchor to put, and metal material is comparatively durable, long service life.
In above-mentioned soft passage nasopharynx part suction catheter, described flexible pipe is made up of polrvinyl chloride.Flexible pipe pliability is good, can arrive nasopharynx part by oral cavity, and then arrives sphenoid sinus, and does not disturb the operation of operating theater instruments in nasal passage.
Compared with prior art, the advantage of this soft passage nasopharynx part suction catheter is: the first, and the pliability of flexible pipe is good, can arrive nasopharynx part by oral cavity, and then arrives sphenoid sinus, and does not disturb the operation of operating theater instruments in nasal passage.The second, sucking head is made up of metal material, also can utilize sucking head self gravitation, its anchor is placed in need attract nasopharynx part or sphenoid sinus in, play lasting sucking action to keep the clear of visual area, thus solve the crowded problem of nasal passage, improve the motility of operation in nasal cavity instrumentation.3rd, during use, hose connection being connected with negative pressure generating device, regulating vacuum magnitude in flexible pipe by pinning negative pressure adjustment hole, simple to operate, easy to use.4th, the smog that multiple attraction aperture is beneficial to flushing liquor, blood and operation technique produce fully attracts.5th, antifouling avoid flushing liquor, blood directly with the finger contact of medical worker, global design is reasonable, and structure is simply, practical.
