Description

Trachea cannula without bite-block

Technical field

The utility model is related to medical apparatus, more particularly to trachea cannula.

Background technology

Oral trachea cannula is clinical operation, anesthesia, emergency resuscitation most common method, and the safety of trachea cannula is fixed It is the guarantee for maintaining patient's effective ventilation, fixed method is generally bite-block plus adhesive plaster.Clinically tooth is put into after being intubated successfully Pad, to fix trachea cannula, and prevent patient sting pipe cause intubation to shrivel, occlusion, influence ventilation.But because bite-block adds mouth Intracavitary foreign matter, causes vestibule of mouth diease gap to increase, and mucous membrane externally exposes in oral cavity, easily causes patient's oral mucosa damage, unfavorable In oral care, injury of teeth is easily caused.And the elderly is because of absence of tooth, when implementing trachea cannula to gerontal patient, bite-block without Method is effectively fixed, and on the one hand intubation is easily slid into oral cavity, or ejects oral cavity by tongue, causes trachea cannula to shift, and is reduced The validity of artificial ventilation.On the other hand because without tooth, bite-block fixes very inconvenient, generation bite-block drops to situation in the mouth.

Utility model content

In order to overcome defect of the prior art, the utility model provides a kind of trachea cannula without bite-block, including Spigot joint, the conduit being connected with spigot joint, cuff is provided with the head end of conduit, and cuff passes through gas tube and sleeve bag gas-filling Joint is connected, and clamping device is provided with the outer wall of airway end, and clamping device includes groove and projection, groove and projection Alternately connect.

In decision design, clamping device also includes rinforcement bar with conduit outer wall contact position.

Further, clamping device at least includes two grooves and three projections

Further, the width of groove is 0.5 centimetre.The shape of projection is selected from square, circular or ellipse.

Further, trachea cannula also includes frenulum, and frenulum sets pro-skin spongy layer with skin contact.

The trachea cannula has following excellent results：Can be applied to front tooth incompleteness can not place the elderly of bite-block.Cause Clamping device is fixedly connected in advance on the conduit of trachea cannula, after trachea cannula is finished, without being additionally put into bite-block simultaneously in oral cavity Bite-block is fixed, it is to avoid the incomplete patient of front tooth using bite-block when being fixed, and bite-block fixes situation about loosely falling into the mouth Occur.It can effectively take care of one's teeth, reduce the probability of oral mucosa lesion, and simplify the operating procedure of trachea cannula, save Nurse uses thing time, improves operating efficiency.

Embodiment

The design is further illustrated with reference to the accompanying drawings and examples.

Trachea cannula as shown in Figures 1 to 3, is fixed without bite-block when in use, and it includes spigot joint 1, connect with intubation The connected conduit 2 of head, is provided with cuff 3, cuff 3 is connected by gas tube 4 with sleeve bag gas-filling joint 5 near the head end of conduit It is logical.Clamping device 6 is provided with the outer wall of airway end, clamping device includes groove 7 and projection 8, groove and projection alternating Connection.Groove is the clenching part position of tooth or gum, and its width is 0.5 centimetre.Patient for adaptation different building shape uses.Projection Shape can be circular or the shape such as ellipse.In a preferred design, projection exists for ellipse to prevent conduit Rotated in oral cavity, and patient comforts when using.Tooth or gum are placed on groove, and the projection on groove both sides is born against The both sides of tooth or gum, can thus avoid intubation from gliding or be pushed out.Clamping device at least includes two grooves and three Projection.Flat in order to prevent airway to be snapped, clamping device 6 is with also including rinforcement bar 9 at the wall contacts of conduit 2.In manufacture tracheae During intubation, clamping device 6 is used and manufactured respectively with the integrally formed mode of conduit 2, or clamping device 6 and conduit 2, Clamping device is socketed and is fixed on conduit afterwards.In a specific design, head end opening of the clamping device 6 apart from intubation (i.e. conduit inclined-plane opening) place about 20cm.Clamping device can select silica gel material and make.

As shown in figure 3, the application of trachea cannula clinically.Hand-held described trachea cannula is stretched on the right side of oral cavity, is led Pipe inclined-plane opening 10 is directed at glottis, when inclined-plane opening has been enter into glottis, slightly to the left or right turn, and conduit is pushed into tracheae up to one Depthkeeping degree.Allow the groove of trachea cannula to be located at teeth portion, allow tooth or gum to be located in groove so that tooth or gum are engaged in recessed At groove 7.Now projection 8 is located at the both sides of tooth or gum, it is to avoid trachea cannula is moved forward and backward.When trachea cannula is placed on Behind correct position, frenulum is wrapped on extrabuccal groove, and one end bypasses after neck and preferably to fix trachea cannula Firmly, further trachea cannula is prevented to be shifted over.Fix to finish in backward cuff 3 when trachea cannula and inject appropriate air, make to lead Pipe 2 is closed with tracheal wall, and intubation is finished.Also include scale, timing observation trachea cannula and the quarter before front tooth on trachea cannula Degree, grasps the situation that trachea cannula is subjected to displacement.

In a preferred design, frenulum uses the bonding mode of VELCRO, can be conveniently adjusted the elastic of frenulum Degree, to change.Frenulum uses pro-skin sponge with skin contact, to reduce damage of the frenulum to skin.

Because trachea cannula carries clamping device, while trachea cannula, clamping device is put in patient's mouth, reduced The operating procedure for taking bite-block to fix, therefore save nurse and use thing time.The design of groove can both be used as teeth portion At occlusion, again can be as the colligation of frenulum at, this not only reduces the part of trachea cannula, make to operate more effective, together When also reduce material cost.The trachea cannula at least includes two grooves, and such design can meet different building shape Patient uses, wide application.Clamping device is made from silica gel material or in one layer of silica gel material of clamping device outer wrap.Work as tooth When encountering clamping device, silica gel has cushioning effect, it is to avoid tooth is damaged.Trachea cannula clamping device design of the present utility model is small Ingeniously, to patient with teeth in use, the damage of tooth can be reduced.To edentulous patients in use, clamping device is solid with conduit in advance Surely link together, it is to avoid clamping device drops to patient in the mouth.
