The wall thickness of the endotracheal tube body 10 is about 1mm (millimeter, the same below), and the wall thickness of the catheter balloon 20 is generally 0.1-0.2mm, which is a relatively common size at present, and if technology upgrade causes two wall thicknesses to change (for example, thinner), the patent is not affected under the condition that the photoetching machine can still open the mold.

For better effect, the lubricant is dried snail mucus. Snail slime: a gland is grown on the foot of the snail and called foot gland, and the foot gland can secrete a very viscous trace, namely snail mucus, also called snail mucus.

The manufacturing method comprises two methods as follows:

first one

S1, opening the mold: and respectively manufacturing a catheter mould and an air bag mould, namely manufacturing a plurality of bulges on the inner walls of the two moulds by a photoetching machine through the technical preparation of the photoetching machine, wherein the distribution condition and the shape of the bulges are matched with the distribution condition and the shape of the lubricant recesses 12.

S2, blow molding: the endotracheal tube body 10 and the tube balloon 20 are manufactured separately, namely:

heating and melting the raw materials for manufacturing the catheter air bag 20, placing the raw materials in an air bag die for blowing, wherein the film material after blowing is tightly attached to the inner wall of the die, forming a lubricant pit 12 at the position corresponding to the bulge, and cooling, shaping and demoulding to obtain the catheter air bag 20 with the lubricant pit 12;

heating and melting the raw materials for manufacturing the endotracheal tube body 10, placing the raw materials in a tube mould for blowing, wherein the film material after blowing is tightly attached to the inner wall of the mould, forming a lubricant recess 12 at the corresponding position of the protrusion, and cooling, shaping and demoulding to obtain the endotracheal tube body 10 with the lubricant recess 12.

S3, fixing: the tracheal catheter body 10 and the catheter air bag 20 are fixedly assembled to form a tracheal catheter product.

And S4, applying the snail mucus on the outer surface of the tracheal catheter product in the step S3, enabling the snail mucus to enter the lubricant pit 12, drying for 9 hours, enabling the snail mucus to be dried and attached to the lubricant pit 12, and removing air in the nano structure.

Second kind

S1, a platen: and (3) preparing a plurality of bulges on the surface of the quartz mould by utilizing a photoetching technology, wherein the distribution condition and the shape of the bulges are matched with the distribution condition and the shape of the lubricant recesses 12, so as to form the stamping plate.

S2, preparing a primary product: a lubricant-free depression 12 of the primary product of the endotracheal tube is made.

S3, imprinting: and (3) placing the primary product of the tracheal catheter in the step (S2) on the stamping plate in the step (S1), heating, inflating, stamping, exhausting and cooling, and removing air bubbles existing between the air bag of the ventilation catheter and the nano stamping template to form the product of the tracheal catheter.

And S4, applying the snail mucus on the outer surface of the tracheal catheter product, enabling the snail mucus to enter the lubricant pit 12, drying for 9 hours, enabling the snail mucus to be dried and attached to the lubricant pit 12, and removing air in the nano structure.

And in the step S2, before imprinting, the imprinting plate in the step S1 is washed for 2 times by using alcohol and deionized water to remove impurities.

The essence of the utility model lies in:

firstly, the lubricant pits are distributed in a lattice manner (also called nano lattice) in a nano scale, and the size of the lubricant pits 12 is relatively small (in the nano scale), so that the friction resistance generated when the structure slides relatively in a human body can be ignored. In other words, the addition of these lubricant recesses 12 to the exterior surface of this patent results in negligible damage to human friction as compared to the friction before addition.

Secondly, snail mucus is coated in the lubricant pit 12 and is dried and attached in the lubricant pit 12, so that the fixation of the snail mucus with the tracheal catheter body 10 and the catheter air bag 20 is completed, and convenience is brought to the packaging, transportation, storage and the like of products.

Finally, after the tracheal catheter enters a human body, under a wet environment of the human body, the lubricant in a dry state in the lubricant pit 12 absorbs body fluid of the human body to form normal snail mucus, the snail mucus restores the original lubricating effect, when the patent product slides in the human body, the patent product is in contact with the human body to generate elastic deformation, the normal snail mucus can be extruded out by the deformation, the normal snail mucus is positioned between the outer surface of the patent product and the human body and serves as a lubricant for sliding friction to form a moisturizing lubricating layer, the friction between the outer wall of the tracheal catheter and the human body is reduced, and the damage to cell tissues of a patient is reduced.

The working principle is as follows:

during its use, connect the joint 11 of endotracheal tube body 10 rear end on the breathing machine, it is internal (in fact be exactly in patient trachea/bronchus) with endotracheal tube body 10 deep-going patient, endotracheal tube body 10, the surface of pipe gasbag 20 receives internal moist environment because of contacting with the patient, the dry lubricant in the emollient sunken 12 resumes lubricating property, form distinctive moisturizing in the nanometer dot matrix, the lubricity, reduce endotracheal tube body 10, pipe gasbag 20 and the patient between the frictional resistance, after the resistance reduces, can reduce the injury to patient's health, reduce the misery that brings the patient, make the patient increase the comfort level.

Meanwhile, the lubricant recess 12 is small in size (nano-scale), so that the smoothness of the outer surfaces of the endotracheal tube body 10 and the catheter air bag 20 is not affected, and the frictional resistance between the endotracheal tube body 10 and the catheter air bag 20 and a patient is not increased.

The tracheal catheter body 10 and the catheter air bag 20 are continuously inserted into the patient, when the tracheal catheter body 10 is at a proper position in the patient (whether the position of the tracheal catheter body 10 is judged by medical personnel), the catheter air bag 20 is inflated through the air bag inflation port 22 and the inflation tube 21, and the catheter air bag 20 is gradually in an expansion state.

The catheter balloon 20, when in the inflated state, serves two functions: first, the pressure between the catheter balloon 20 and the patient's body increases, and at the same time, the contact area between the catheter balloon 20 and the patient's body also increases, so the maximum static friction between the catheter balloon 20 and the patient's body increases, which makes the catheter balloon 20 and the patient's body relatively stationary, i.e.: completing the work of fixing the tracheal catheter body 10 in the body of the patient; secondly, the catheter air bag 20 cuts off the connection between the trachea/bronchus of the patient and the outside, so that the trachea and the lung of the patient become a closed space, the temporary artificial respiration of the patient is facilitated, the temporary artificial respiration is performed through an external respirator, and the tracheal catheter body 10 only plays a role of an air passage.

See the prior art for further details.

While the preferred embodiments of the present invention have been described, it should be understood that various changes and modifications may be made therein by those skilled in the art without departing from the general concept of the invention, and it is intended that such changes and modifications be considered as within the scope of the invention.
