SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a tracheal catheter with simple structure and reasonable design for solving the problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides an endotracheal tube, includes the pipe main part, the pipe main part includes cover bag section and glottal section, cover bag section is located the interior end head portion of pipe main part, the cross section footpath length of glottal section is less than the cross section footpath length of cover bag section, pipe main part integrated into one piece, the surface of cover bag section is connected with cover bag spare, cover bag spare is connected with the cover bag pipe, the other end of cover bag pipe is connected with the end of aerifing.
As a further preferred aspect of the present invention, the outer surface of the catheter main body is extended and protruded with a reinforcing member toward opposite sides thereof.
As a further optimization scheme of the utility model, the reinforcement is made of medical plastic.
As a further preferred embodiment of the present invention, the cuff tube is fixedly attached to the inner diameter surface of the catheter main body.
As a further optimization scheme of the utility model, when the external diameter of the cuff section is 10.2mm and the internal diameter is 7.5mm, the external diameter of the glottic section is 8.8mm and the internal diameter is 6.5 mm; when the cuff section has an outer diameter of 9.6mm and an inner diameter of 7.0mm, the glottic section has an outer diameter of 8.3mm and an inner diameter of 6.0 mm.
The beneficial effects of the utility model reside in that: the utility model is provided with the cuff section with larger diameter and the glottic section with smaller diameter, the thicker cuff section can avoid the problems of the escape of the conduit, too high cuff pressure, insufficient sealing and the like caused by the too thin tracheal catheter, the ventilation safety of the tracheal catheter is improved, and the thinner glottic section can provide good visual field of the glottic area, which is beneficial to the effective operation; the oral cavity is small in occupied space, reduces the risk of injury and infection of oral cavity tongue mucosa, does not need additional consumables, and has good economy and safety; whole device simple structure, convenient operation uses in a flexible way, and the glottic area operation of being convenient for uses, and the effectual good field of vision in glottic area that has improved reduces the danger that the pipe footpath undersize brought, reduces the injury oral cavity tongue mucosa and harms the infection risk, convenient to popularize and use.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic structural view of the reinforcing member of fig. 1 according to the present invention;
fig. 3 is a schematic view of the position structure of the cuff tube of the present invention.
In the figure: 1. a cuff section; 2. a glottic section; 3. a reinforcement; 4. a cuff member; 5. sleeving a bag tube; 6. An inflation end; 7. and the outer end of the guide pipe.
Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
Example 1
As shown in fig. 1-3, an endotracheal tube comprises a tube body, the tube body comprises a cuff section 1 and a glottic section 2, the cuff section 1 is located at the inner end part of the tube body, the section diameter length of the glottic section 2 is smaller than that of the cuff section 1, the tube body is integrally formed, a cuff member 4 is connected to the outer surface of the cuff section 1, a cuff tube 5 is connected to the cuff member 4, and an inflation end 6 is connected to the other end of the cuff tube 5.
In this embodiment, the radial lengths of the cuff section 1 and the glottic section 2 are further defined, when the cuff section 1 has an outer diameter of 10.2mm and an inner diameter of 7.5mm, the glottic section 2 has an outer diameter of 8.8mm and an inner diameter of 6.5 mm; when the cuff section 1 has an outer diameter of 9.6mm and an inner diameter of 7.0mm, the glottic section 2 has an outer diameter of 8.3mm and an inner diameter of 6.0 mm. The tracheal tube diameter prepared by the data used for the glottis area operation is beneficial to the use of the glottis area operation, can provide a good visual field of the glottis area, can avoid the problems of the escape of the tracheal tube, the overhigh pressure of the cuff, the insufficient sealing and the like caused by the too thin tracheal tube, and improves the ventilation safety of the tracheal tube.
