Description
Technical Field
The utility model relates to the field of medical instruments, in particular to a tracheal catheter with high ventilation volume.
Background
The tracheal catheter is an important rescue technique commonly used in emergency treatment work, and is one of the most widely applied, most effective and most rapid means in respiratory tract management.
The insertion head of the prior tracheal catheter mostly adopts a beveling mode, the air flow of the plug is small, and after the plug is inserted, the beveling sharp corner easily stimulates the respiratory tract, so that the discomfort of a patient is caused. In addition, sputum scab is easily generated between the oblique tip and the respiratory tract, which causes the obstruction of the respiratory tract, increases the resistance of the respiratory tract, and causes dyspnea and even asphyxia.
Therefore, a patient with an endotracheal tube needs an organ catheter that can improve ventilation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problems and provides a tracheal catheter with high ventilation volume. In order to achieve the purpose, the utility model adopts the following technical scheme:
a high-ventilation tracheal catheter comprises a catheter body, wherein the front end of the catheter body is an insertion end, the tail end of the catheter body is provided with a connector, the front part of the insertion end is an arc-shaped insertion head, two sides of the insertion head are provided with arc-shaped first openings, the insertion end is provided with second openings at positions, far away from the insertion head, of the first openings, the second openings are oval, and the second openings are circumferentially arrayed on the catheter body;
the tube body is provided with an inflatable bag near the insertion end, and an inflatable tube for inflating the inflatable bag is arranged near the connecting head.
As a refinement, the number of the second openings is 4.
As an improvement, a reinforcing rib is arranged at the position of the insertion head.
As an improvement, the inflation tube penetrates into the inflation bag from the tube wall of the tube body.
As an improvement, the surface of the pipe body is provided with scales.
The utility model has the advantages that:
the insertion end of the utility model is provided with a first opening at two sides, and the rear end of the first opening is provided with a second opening in a circumferential array. Can improve the ventilation capacity of the tracheal catheter and prevent mucus or sputum scab in the respiratory tract from blocking the tracheal catheter.
The utility model can keep the self shape and structure stable after being inserted into the air passage, prevent the reduction of the pore diameter of the opening caused by deformation and always keep good ventilation capacity.

Detailed Description
The present invention will be described in detail and specifically with reference to the following examples so as to facilitate the understanding of the present invention, but the following examples do not limit the scope of the present invention.
Example 1
The embodiment discloses a tracheal catheter with high ventilation volume, which comprises a catheter body 1. The front end of the tube body 1 is an insertion end 2, and the tail end is provided with a connector 3. The front part of the insertion end 2 is an arc-shaped insertion head 21, and arc-shaped first open holes 22 are formed in two sides of the insertion head 21. The insertion end 2 is provided with second openings 23 at positions, far away from the insertion head, of the first openings, the second openings 23 are oval, the number of the second openings 23 is 4, and the second openings are circumferentially arrayed on the tube body 1.
The tube body 1 is provided with an inflatable bag 4 at the position close to the insertion end 2, and the tube body 1 is provided with an inflatable tube 5 for inflating the inflatable bag 4 at the position close to the connector 3. The surface of the tube body 1 is provided with scales 6.
The inflation tube 5 penetrates into the inflation bag 4 from the tube wall of the tube body 1.
Example 2
The embodiment discloses a tracheal catheter with high ventilation volume.
The embodiment is provided with a reinforcing rib 24 at the position of the insertion head 21. The ribs 24 may hold the insertion head 21 in an expanded state to prevent twisting or deformation during insertion.
The embodiments of the present invention have been described in detail above, but they are merely exemplary, and the present invention is not equivalent to the above described embodiments. Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention. Accordingly, it is intended that all equivalent alterations and modifications be included within the scope of the utility model, without departing from the spirit and scope of the utility model.
