Abstract
An endotracheal intubation fixing device comprises a baffle and a groove-shaped channel. The baffle is made of hard materials, the groove-shaped channel is made of elastic materials, a protruding tooth biting portion is arranged in the middle of the baffle, the shape of the tooth biting portion is matched with that of the upper end of the groove-shaped channel, the upper end of the groove-shaped channel is wrapped and fixedly connected with the tooth biting portion, and the composite tooth biting portion has a hard inner portion and a soft outer portion. The tooth biting portion of the endotracheal intubation fixing device has the hard inner portion and the soft outer portion, polycarbonate (PC) materials on the inner portion of the tooth biting portion have enough hardness to prevent the channel from being closed due to the fact that the channel is bitten, and thermoplastic elastomer (TPE) materials on the outer portion of the tooth biting portion have enough softness to protect teeth of patients.
Description
Technical field
The present invention relates to the technical field of medical equipment, particularly relate to a kind of tracheal cannula fixer.
Background technology
Endotracheal intubation is one of important measures of successfully rescuing the critical patient, and traditional tracheal intubation fixing means is to continue to use bite-block and tracheal intubation are directly pasted patient both sides buccal after with immobilization with adhesive tape more always, because fixing means is simple and crude, so many drawbacks are arranged; Adopt immobilization with adhesive tape, patient is done not feel like oneself, chafe causes inflammation or epidermis festers; The long easy adhesion of adhesive plaster indwelling time is agglomerating, be difficult for changing, and very easily pollution causes secondary infection to take place, and causes extra misery to the patient.
Special-purpose tracheal cannula fixer has appearred in recent years, be placed in the population specially, namely can be used to insert trachea, also can be used to insert sputum aspirator tube, for fear of patient trachea is stung closure, existing tracheal cannula fixer all is to adopt hard material to make, though avoided stinging the problem of closing like this, but easily patients teeth is damaged, have much room for improvement.
Summary of the invention
The objective of the invention is provides a kind of tracheal cannula fixer in order to address the above problem.
Technical scheme of the present invention is: a kind of tracheal cannula fixer, comprise baffle plate, grooved passage, described baffle plate is hard material, the grooved passage is elastomeric material, the baffle plate middle part is provided with the tooth of projection and stings portion, tooth is stung the shape of portion and the upper end form fit that grooved passes through, and the upper end of grooved passage parcel also is fixedly connected on tooth and stings in the portion, and the tooth after compound is stung portion in soft firmly outward.
The upper end of described grooved passage is wrapped in tooth by hot melt encapsulate technology and stings in the portion.
The outer surface that described tooth is stung portion is provided with several annular ditch.
The Lower Half of described grooved passage is arc.
The upper surface of described catch is provided with steady pin, perforation, fixed leg.
Described baffle plate is the PC material, is Merlon; The grooved passage is TPE material, i.e. thermoplastic elastomer (TPE).
Beneficial effect of the present invention
The tooth portion of stinging of tracheal cannula fixer is interior hard outer soft, and inner PC material has enough hardness and avoids passage to be snapped closure, and outside TPE material has enough pliabilitys again and protects patients teeth.

The specific embodiment
Embodiment: referring to Fig. 1, a kind of tracheal cannula fixer among the figure, comprise baffle plate, grooved passage, described baffle plate is hard material, the grooved passage is elastomeric material, and the baffle plate middle part is provided with the tooth of projection and stings portion, and tooth is stung the shape of portion and the upper end form fit that grooved passes through, the upper end of grooved passage parcel also is fixedly connected on tooth and stings in the portion, and the tooth after compound is stung portion in soft firmly outward.The upper end of described grooved passage is wrapped in tooth by hot melt encapsulate technology and stings in the portion.Hot melt encapsulate technology can make the upper end of grooved passage and tooth sting the firm combination of portion, and the outer surface that described tooth is stung portion is provided with several annular ditch, can improve the adhesion that grooved passage upper end and tooth are stung portion.The Lower Half of described grooved passage is arc.The upper surface of described catch is provided with steady pin, perforation, fixed leg.Described baffle plate is the PC material, and the grooved passage is the TPE material.
During use the grooved passage of this tracheal cannula fixer is inserted patient's bottleneck throat, catch is positioned at outside the lip, and the tooth portion of stinging is positioned between the lower tooth, is fixed on by bandage on people's the neck, just can use, and can insert trachea, also can insert sputum aspirator tube.
