Description

Novel tracheal catheter capable of reducing slippage

Technical Field

The utility model relates to a endotracheal tube technical field especially relates to a novel endotracheal tube who reduces the slippage.

Background

In the clinical process of diagnosing and treating critically ill patients, the retention of each pipeline is a common treatment measure. However, the surface of the currently used tracheal catheter is smooth, and the conventional mode of fixing the tracheal catheter by using an adhesive tape or a bite block has the phenomenon that the fixed part is loosened due to the long time and secretion pollution, so that the fixed part of the tracheal catheter slips or shifts, and the use is not facilitated. To this end, we propose a new endotracheal tube that reduces slippage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a novel tracheal catheter for reducing slippage.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a reduce novel endotracheal tube of slippage, includes the air duct, the surface cover of air duct tail end is equipped with outer hoop, the internal surface of the air duct that outer hoop corresponds is settled there is interior hoop, the inside of the interior anchor ring of outer hoop embedding to the air duct surface, the inside of the outer anchor ring's of interior anchor ring embedding to the air duct internal surface, the screw thread channel has been seted up to the internal surface of the air duct that interior hoop the place ahead corresponds.

Preferably, an inflatable air bag is arranged outside the front end of the air duct, two ends of the inflatable air bag are tightly connected with the outer surface of the air duct, an inflatable tube is communicated with the inside of the inflatable air bag, and the tail end of the inflatable tube is connected with an inflating nozzle.

Preferably, the front part of the inflation tube is embedded in the outer surface of the air guide tube, and the rear part of the inflation tube extends to the outer side of the outer surface of the air guide tube.

Preferably, the inner hoop and the outer hoop are both rubber rib rings.

Preferably, the length of the thread groove is 1-1.2 CM.

The utility model provides a novel endotracheal tube who reduces slippage, beneficial effect lies in: this scheme is at the in-process that uses, when the bite-block is inserted and is established the tail end of air duct, interior hoop and outer hoop homoenergetic inflation deformation, interior hoop under the inflation deformation state can strengthen its and the bite-block contact site between frictional force, outer hoop under the inflation deformation state can strengthen the frictional force between outer hoop department air duct internal surface and the bite-block contact site, and the thread groove can strengthen the frictional force between thread groove department air duct internal surface and the bite-block contact site this moment, and then make the air duct can be firm with the bite-block contact, can effectively reduce the condition that takes place slippage or aversion between air duct and the bite-block promptly, and then can ensure whole endotracheal tube's safe in utilization, be favorable to using widely.

Drawings

Fig. 1 is a schematic structural view of the novel endotracheal tube for reducing slippage according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1, a novel tracheal catheter for reducing slippage comprises an airway tube 1, wherein an outer hoop 6 is sleeved on the outer surface of the tail end of the airway tube 1, an inner hoop 5 is arranged on the inner surface of the airway tube 1 corresponding to the outer hoop 6, and the inner hoop 5 and the outer hoop 6 are rubber rib rings.

The inner ring surface of the outer hoop 6 is embedded into the outer surface of the airway tube 1, the outer ring surface of the inner hoop 5 is embedded into the inner surface of the airway tube 1, the inner surface of the airway tube 1 corresponding to the front of the inner hoop 5 is provided with a thread groove 7, and the length of the thread groove 7 is 1-1.2 CM.

The outside of the front end of air duct 1 is equipped with inflatable balloon 2, the both ends of inflatable balloon 2 and the surface zonulae occludens of air duct 1, the inside intercommunication of inflatable balloon 2 has gas tube 3, the trailing end connection of gas tube 3 has charging connector 4, insert the in-process that uses to patient's lung at air duct 1, accessible charging connector 4 aerifys in to inflatable balloon 2 through gas tube 3, inflatable balloon 2 expands under the inflation state, the surface of expanded inflatable balloon 2 contacts with the surface of patient's lung pipe, can realize the fixed positioning of air duct 1 front end in patient's lung pipe this moment promptly.

The front part of the inflation tube 3 is embedded in the outer surface of the air duct 1, and the rear part of the inflation tube 3 extends to the outer side of the outer surface of the air duct 1.
