Description

Disposable auripuncture drainage device

Technical field

The utility model belongs to the field of medical instrument technology, is specifically designed a kind of ear treatments use for hals,Nasen und Ohrenheilkunde Disposable auripuncture drainage device.

Background technique

Secretory otitis media is using hydrotympanum and conduction deafness as the middle ear apyetous inflammatory disease of main feature. Middle ear effusion can be serosity omission timber or diffusate, also can be mucus, when being due to Eustachian tube poor aeration, ambient atmos are not Can enter middle ear, original gas is gradually by mucosa absorption in middle ear, intracavitary formation negative pressure, cause middle ear mucosa blood vessel dilatation, Extravasated blood, Vascular Permeability enhance, and omission timber occur in tympanum.Therefore middle ear effusion is removed, middle ear ventilation drainage is improved and is controlled Treat the principle of reatment that the cause of disease is this disease.Puncture into tympanic cavity drawing liquid be remove middle ear effusion be improve middle ear ventilation drainage treatment method it One, clinically it is widely applied.When traditional operation, doctor is under patient's local anaesthesia, with tympanocentesis needle from drum under sterile working Film front lower place is pierced into tympanum, extracts hydrops.Syringe is connect in the tail portion of syringe needle when extracting hydrops, with syringe extraction tympanum product Liquid.It is likely to occur in extraction process because syringe needle rotates during connection syringe, pressure when position changes and syringe extracts Power is uneven, extraction hydrops occurs and is not thorough, and syringe needle rotation increases the pain of patient, works poor, and influences treatment etc..

Summary of the invention

The purpose of this utility model is deficiency in view of the above technology, provides disposable auripuncture drainage device, is realized The purpose of this utility model is adopted the technical scheme that: a kind of disposable auripuncture drainage device, includes auripuncture Needle, needle guard and single-blade needle handle, tympanocentesis needle connect drainage tube, it is characterised in that: drainage tube connects negative pressure by connecting needle and draws Flow tube, the tympanocentesis needle, drainage tube, connecting needle and negative-pressure drainage tube are connected together, and cover on the drainage tube Fill tube sealing clamp.The negative-pressure drainage tube is equipped with scale.The utility model increases tube sealing at auripuncture drainage tube Folder, drainage tube tail portion increases negative-pressure drainage tube.

The utility model is easy to operate；Shorten the Er Nei time in operating process in patient and reduces patient's pain, Yi Peihe；Knot Structure is simple, at low cost；Infection probability is reduced, is suitable for promoting.

Specific embodiment

Referring to attached drawing, a kind of disposable auripuncture drainage device includes tympanocentesis needle 1, needle guard 2 and single-blade needle handle 3, tympanocentesis needle 1 connects drainage tube 4, it is characterised in that: drainage tube 4 connects negative-pressure drainage tube 7 by connecting needle 6, described Tympanocentesis needle 1, drainage tube 4, connecting needle 6 and negative-pressure drainage tube 7 are connected together, and are set with tube sealing on the drainage tube 4 Folder 5.The negative-pressure drainage tube 7 is equipped with scale 8.The utility model increases tube sealing clamp 5 at auripuncture drainage tube, Drainage tube tail portion increases negative-pressure drainage tube 7.

When operation, medical practitioner sterile's external auditory canal and eardrum, totokaine dough sheet anaesthetize eardrum, after pulling out needle guard 2, tympanocentesis needle 1 is pierced into eardrum and fixed needle handle 3 in eardrum front lower place, and 4 tail portion of drainage tube is connected to negative-pressure drainage tube 7 with connecting needle 6, is beaten Break a seal pipe clamp 5, and hydrops is drawn in tympanum.The number of the 8 observable hydrops of scale on negative-pressure drainage tube 7 passed through.

Present apparatus structure is simple, easy to use, drainage thoroughly, patient's pain less, be conducive to doctor operate and reduce concurrently The disposable Tympanostomy device that disease occurs.The common therapeutic equipment of auripuncture drawing liquid is Tympanostomy device, the method behaviour Make simple and easy, economical, doctor is easily mastered, and patient is easily accepted by, and children that are adult and working good can be in hals,Nasen und Ohrenheilkunde door Operation is examined to implement.
