Abstract
The utility model provides a medical oral pressure proof one-time guiding-tube of a tracheal cannula, which has the characteristics of an arc external appearance of a common guiding-tube and a hollow guiding-tube, and a blown sleeve cystis included at the front end of the guiding-tube is connected with an extricate aerating device arranged at the back end of the guiding-tube via a gas-filled guiding-tube arranged in the wall of the guiding-tube. The utility model is characterized in that annular pressure proof materials are inlayed in the pipe wall of the back end portion of the guiding-tube, thereby replacing bite rims action, avoiding generation of danger complication due to separation of the guiding-tube and the bite rims, simultaneously reducing contents of a mouth cavity, and the utility model has the advantages of easy fixation, beauty and the like, and dual functions equipped by one tube..
Description
Technical field
This utility model belongs to medical apparatus, particularly a kind ofly prevents that through the oral cavity tracheal intubation conduit from shriveling, and blocks the disposable pneumo cannula conduit of ventilation.
Background technology
The present tracheal intubation of using clinically, the rescue that is applied to the critical patient improves ventilation and corrects anoxia more, or do and safeguard the eupnea function of exchange in the anesthesia surgery process, with tracheal intubation conduit band cover capsule side one end through the oral cavity, swallow to larynx, be inserted in the main trachea by glottis, and conduit is retained in outside the oral cavity other end and is connected with artificial respirator and carries out mechanical ventilation, reaches the effective exchange of oxygen one carbon dioxide through lung, safeguards that people's physiological function is stable.But because the tracheal intubation conduit is after finishing the intubate operation, must or mould firmly with circular ebonite rod and wait article to glue with sticking cream to be held together as bite-block and conduit, be pasted on the buccal both sides, the purpose that conduit and bite-block together are fixed between the lower tooth is to prevent that front tooth is to the tooth interlock, it is flat to cause conduit to be snapped, the influence ventilation causes the respiratory tract complication.
Summary of the invention
This utility model purpose is that the anti-material of pressing is provided on the basis of original pipe intubate, and being embedded in tracheal intubation needs between the catheter wall of fixed position, places garden type ebonite rod in addition or article such as moulds firmly as bite-block to substitute.Become one because of manufacturing simultaneously with disposable pneumo cannula conduit; do not separate and avoided in the past patient because of to the tooth masticatory movement; misfit; break-in etc.; cause bite-block and tracheal intubation conduit separation case to take place; in a single day bite-block breaks away from tooth cavity and slides to outside buccal or the mouth; the tracheal intubation conduit loses protection; easily sting the flat dysfunction of ventilation that causes, respiratory system complication occurs, the lighter's anoxia; weight person causes the danger of death by suffocation; and movable independent bite-block is often not firm because of fixing in clinical use, and bite-block is really up to the mark to oral mucosa; periglottis; buccal mucosa, tissues such as tooth cause damage, cause and dampen; laceration; hemorrhage; complication such as loss of tooth.
This utility model technical solution problem, the technical scheme that is adopted is; The anti-disposable pneumo cannula conduit of pressing of a kind of medical per os, tracheal intubation conduit and the bundle relation of bite-block in the intubate operating process have been changed, and make that two kinds of utensils are integrated, neither influence the tracheal intubation catheter functions and can substitute the bite-block effect again, reduced this operation sequence simultaneously, avoid the complication that causes thus, thereby also reduce the oral cavity content, kept perfectly image appearance.
The beneficial effects of the utility model are, on the basis of tracheal intubation conduit, fixedly inlaying anti-pressure material between the front tooth between the duct wall in the 6-8 centimetre scope, prevent that front tooth is involutory flat to stinging of conduit, also reduced the program of putting into bite-block again during operation, because of incorporate advantage, the slippage after avoiding conduit and bite-block being fixing separates the generation of the dangerous complication that causes simultaneously.
Description of drawings
Accompanying drawing, this utility model structural representation
As shown in the figure
The anti-disposable pneumo cannula conduit of pressing of a kind of medical per os, it has arcual outward appearance of common oral trachea cannula conduit and hollow conduit characteristics, being divided into catheter proximal end 1. body ends 2. tail ends 3. according to structure is included in the thin and soft inflatable cuff of catheter proximal end 4. and is connected by traveling inflating catheter 5. in the extension catheter wall and the tail end of conduit aerating device 6. that dissociates, the anti-material of pressing is embedded in the middle of the tail end of conduit tube wall ringwise, its length range is the 4-10 centimetre, and the anti-material two ends 8. of pressing are streamlined change.The specific embodiment
The anti-disposable pneumo cannula conduit of pressing of a kind of as shown in the figure medical per os, during use, laryngoscope is inserted the oral cavity exposed larynx, with the anti-disposable pneumo cannula conduit of pressing of per os, through the oral cavity vestibule, oral cavity proper is to bottleneck throat, with catheter proximal end 1. be included in front end inflatable cuff 4. and insert 4-6 centimetre in the main trachea by glottis, catheter body end 2. is positioned at pharynx and oral cavity proper position, tail end of conduit 3. and the anti-pressure material 7. that is embedded between the tail end catheter wall just place between the front tooth, played the effect that bite-block prevents to shrivel tube chamber, then withdraw from laryngoscope, with sticking cream tail end of conduit is fixed on the outside buccal both sides, oral cavity, connect on the aerating device 6. with syringe then, through the inflating catheter 5 of aerating device 6. by being attached thereto, inflation expands it to stop up around trachea lacuna gas to the lung and can not reversely flow out from the oral cavity internal return in the conductive pipe front end inflatable cuff, then connect respirator connecting duct tail end tube chamber pedestrian worker ventilation.
Claims (6)
1. a medical per os prevents pressing disposable pneumo cannula conduit, it has the curved appearance and the hollow conduit characteristics of common conduit and is included in the front end inflatable cuff, this cover capsule is connected by the free aerating device of inflating catheter in the catheter wall and tail end of conduit, it is characterized in that; Inlay the anti-material of pressing of annular between the tube wall at tail end of conduit position, the hardness that has changed tail end of conduit has substituted the bite-block effect, reaches tracheal intubation conduit, the dual-purpose dual usefulness of bite-block one pipe.
