Description

soft-head trachea cannula

Technical Field

The utility model belongs to the technical field of medical equipment, in particular to soft-head trachea cannulas.

Background

In medical work, the tracheal intubation through oral cavity or nasal cavity is common, rapid and effective artificial airway establishment measures, but during intubation, the insertion end of the tracheal intubation is easy to damage surrounding tissues, and the surface of the tracheal mucosa is often damaged because the insertion end of the tracheal intubation rubs against the trachea of a human body.

In addition, because the supporting area of the air bag is relatively small, the unit pressure is high, steps are advanced to deepen the injury of the capillary vessel of the mucous membrane of the airway of the human body, the operation risk is increased, and serious complications and sequelae are caused, thereby directly influencing the popularization and application of the technology.

SUMMERY OF THE UTILITY MODEL

To the technical problem who exists among the prior art, the utility model provides an kinds of soft head trachea cannula, the damage of trachea mucosa surface that the insertion end of reducible trachea cannula caused when inserting.

In order to solve the technical problem, the utility model discloses a technical scheme is:

soft head trachea cannula, including pipe body and gasbag, the end of inserting of pipe body is equipped with soft plug, soft plug and pipe body coaxial axle center set up, gasbag and pipe body coaxial axle center set up, just the middle part surface of gasbag is the face of cylinder, the both ends of gasbag are connected with soft plug and pipe body respectively.

Preferably, the end of the soft plug for insertion into the nasal or oral cavity has a beveled cut.

Preferably, the soft plug is in concave-convex fit connection with the pipe body, and the inner diameter and the outer diameter of the soft plug are equal to those of the pipe body.

Preferably, the inner wall of the end of the soft plug for inserting into the nasal cavity or the oral cavity is provided with a groove for storing interstitial fluid.

Preferably, the bladder is connected to the outer wall of the tube body and the soft plug by means of bonding.

Compared with the prior art, the utility model discloses the beneficial effect who has is: the utility model discloses a soft plug and cylindrical surface's gasbag has avoided the damage to trachea mucous membrane surface when inserting the air flue, the security when having guaranteed the use.

Drawings

Fig. 1 is a schematic view of a partial cross-sectional structure of kinds of soft-head endotracheal tubes according to the present invention.

Detailed Description

So that those skilled in the art can better understand the technical solution of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the embodiment of the utility model discloses kinds of soft head trachea cannula, including pipe body 1 and gasbag 2, the end of inserting of pipe body 1 is equipped with soft plug 3, and soft plug 3 sets up with the axle center with pipe body 1, and gasbag 2 is through the mode that bonds and pipe body 1 and soft plug 3's outer wall connection, and gasbag 2's middle part surface is the face of cylinder, and gasbag 2's both ends are connected with soft plug 3 and pipe body 1 respectively, advance step like this and guaranteed the security when using, prevent that soft plug 3 from breaking away from and cause the life hazard to the patient.

In this embodiment, the end of the soft plug 3 for insertion into the nasal or oral cavity has a beveled cut.

In this embodiment, the soft plug 3 is connected to the tube body 1 in a concave-convex fit manner, and the soft plug 3 is equal to the tube body 1 in both inner diameter and outer diameter.

In the embodiment, the inner wall of the end of the soft plug 3 for being inserted into the nasal cavity or the oral cavity is provided with the groove 4 for storing the tissue fluid, so that the tissue fluid is temporarily stored and then cleaned after the intubation tube is pulled out, the workload is reduced, and the normal use function of the intubation tube is not influenced.

The utility model provides a soft first trachea cannula's theory of operation is, under aseptic condition, aerify earlier gasbag 2 confirm 2 gastightness of gasbag take out gas after, soft plug 3 inserts the air flue of patient's oral cavity or nasal cavity, after soft plug inserts targets in place, can fix the pipe body in the air flue after aerifing gasbag 2. When guaranteeing effective ventilation of patient in the operation, can alleviate the damage to the air flue when putting the pipe through soft plug 3, the excircle is when the gasbag 2 of face of cylinder is on supporting the air flue, is convenient for increase the support area when fixed in the air flue, can alleviate the extrusion of gasbag 2 to the air flue mucous membrane, avoids mucous membrane capillary's damage.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
