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.
Accompanying drawing explanation
Fig. 1 is this utility model structure top view;
Fig. 2 is this utility model structural front view;
In figure: 1-bite, 2-intubate fixed part, 3-through hole, 4-hook, 5-fixing band.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model discloses a kind of fixator for tracheal cannule, comprise bite-block, described bite-block comprises bite 1 and intubate fixed part 2, described bite 1 is suitable with the tooth of oral cavity one side, bite 1 is curved, bite 1 front end contacts with front tooth, rear end contacts with backteeth, front end width is less than rear end width, intubate fixed part 2 is connected in bite 1 front end outside and protrudes laterally, described intubate fixed part 2 is provided with axially extending bore 3, intubate fixed part 2 offers the breach of axial perforation away from one end of bite 1, described breach is communicated with through hole 3, indentation, there is provided with the governor motion that regulates through hole 3 sizes, described governor motion is bolt and nut governor motion, facilitate tracheal intubation to put into and take out, easily regulate the position of tracheal intubation simultaneously, the both sides that intubate fixed part 2 protrudes bite 1 are connected with fixing band 5, fixing band 5 is the soft bag of elasticity, bite-block is elastomeric material, in order to the occlusal surfaces of teeth of fitting, while intubate fixed part 2 lordosis, can guarantee that bite 1 is in mouth, but intubate fixed part 2 is outside mouth, convenient adjusting, bite 1 and intubate fixed part 2 are integral type simultaneously, greatly simplify the structure.
