Description

Fixator for tracheal cannule

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of fixator for tracheal cannule.

Background technology

The fixing means of tracheal intubation is mainly two kinds of modes at present, and the first is to be bonded on the face with adhesive plaster, i.e. immobilization with adhesive tape method; The second is to adopt holder to fix.

First kind of way has following defect: 1, easily damage patient's skin, especially elderly patients or have the patient of facial injury, facial edema; 2, fixed effect is limited, is applied in when high heat waits patient with it and easily because of sweat, allows adhesive plaster lose being stained with property; While 3, carrying out mouth care, need two people to coordinate just and can carry out (people holds up pipe, one man operation), waste of manpower; 4, oral cavity is sealed by adhesive plaster, inconvenient clean-up port luminal sectetion thing; 5, repeatedly paste and can cause after endotracheal tube the stickup part glue of endotracheal tube residual, above some oral secretions are easily trapped in, form bacteria culture media, cause patient to have the danger of infection.

Existing holder has laterally spiral and longitudinal spiral formula, and these two kinds of modes all exist following defect: 1, bite-block is very hard, easily damages patient's front tooth; When 2, carrying out mouth care, all need to take off at every turn, and need operated by two people just can carry out (people does mouth care, and it is anti-slip that a people helps tracheal intubation), waste of manpower; 3, take oral cavity portion area excessive, inconvenient clean-up port luminal sectetion thing; 4, fixing band is adhesive type, fixing insecure, its fixedly source of strength be the friction (binding face is simultaneously covered with barb, and one side is fine hair face) of two faces, long-time use easily loses its function.

Summary of the invention

This utility model aims to provide a kind of fixator for tracheal cannule, and it is simple in structure, and fixed form is reliable and stable, takies oral cavity area little, is convenient to clean-up port luminal sectetion thing, and the while is easy damaged patient tooth not.

The technical solution of the utility model is a kind of fixator for tracheal cannule, comprise bite-block, described bite-block comprises bite and intubate fixed part, the tooth of described bite and oral cavity one side is suitable, intubate fixed part is connected in bite, and is positioned at bite one end and protrudes laterally, and described intubate fixed part is provided with axially extending bore, the both sides that intubate fixed part protrudes bite are connected with fixing band, and bite-block is elastomeric material.

Preferably, described intubate fixed part offers the breach of axial perforation away from one end of bite, and described breach is connected with through hole, and indentation, there is provided with the governor motion that regulates hole size, and described governor motion is preferably bolt and nut governor motion.

Preferably, between described fixing band and intubate fixed part, by hook, be connected.

Preferably, described fixing band is the soft band of elasticity.

Preferably, the thickness of described bite is 5mm-20mm, and width is 8mm-40mm.

Preferably, the thickness of bite is 9mm-14mm, and width is 8mm-25mm.

Preferably, described through-hole diameter is 3mm-8.2mm.

Preferably, described bite-block bite is curved, and its front end contacts with front tooth, and rear end contacts with backteeth, and front end width is less than rear end width.

Preferably, the material of described bite-block is medical macromolecular materials or medical composite material.

Preferably, the material of described bite-block is medical silica-gel, medical resin, medical grade rubber or medical plastic.

This utility model is simple in structure, easy to use, is exposed to extrabuccal part few, attractive in appearance; Only take half of oral cavity, only need a people can carry out the operations such as mouth care, effectively save clinical manpower; Because only take half of oral cavity space, can carry out very easily the cleaning of oral secretion simultaneously; About fixture can intermodulation, avoids occurring that a side repetitious stimulation causes unpredictable damage; Bite-block is made for slightly elastic material, and stress point transfers to backteeth by labial teeth, and stress surface is a plurality of by single transfer, is keeping aspect tooth open configuration, can effectively preventing the damage of tooth; Fixing means is the soft band pothook type of elasticity, and fixed form is reliable and stable, is applicable to applying clinically.
