Description

Tracheal catheter convenient to guide

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a tracheal catheter convenient to guide.

Background

Endotracheal tubes are medical devices that are inserted into the trachea and/or bronchi of a patient to create a temporary artificial respiratory pathway for the patient, particularly for patients who are unable to breathe spontaneously. In the tracheotomy process, an opening of about 1cm is firstly cut on the front wall of a trachea, then a sleeve is inserted downwards in a way of turning at 90 degrees after the vertical opening of the sleeve enters, the traditional tracheal catheter comprises an inner core and an outer tube, the part of the inner core penetrating through the outer tube is directly connected with a guide head, in the turning and downwards inserting process, because the section of the inner core head is hard, the rear wall of the trachea is easily damaged, and for a surgeon who just begins to perform tracheotomy, the probability of rear wall damage is increased without guidance action and the skill is not skilled

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a tracheal catheter convenient to guide.

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

the utility model provides a convenient endotracheal tube who guides, is including overlapping the inner core and the outer tube of establishing each other, and the part that the outer tube was stretched out to the inner core is equipped with the guide section, and the guide section includes extension section and first guide head, and first guide head is located one side setting that the inner core was kept away from to the extension section.

The extension section is straight tubular structure, and the external diameter of extension section is the same with the diameter of first guide head left end.

The extension section and the inner core are integrally formed.

The first guide head is connected with the inner core, the extension section is of a flat plate structure after being unfolded, two ends of the extension section are bonded with glue after the periphery of the extension section is unfolded, and the extension section is tightly matched with the inner core.

The one end that the outer tube was stretched out to the inner core is equipped with the second guide head the same with first guide head size, and the one end that the extension section is close to the inner core is equipped with the recess that is used for holding the second guide head, and the second guide head holds in the recess and with extension section tight fit.

The extension section is provided with an injection hole, the injection hole extends to the groove, and a certain gap is reserved between the second guide head and the groove and used for injecting glue.

The utility model has the beneficial effects that: at the direct extension section that increases of inner core and guide head, this structure compares in only guide head when the guide, and the guide section is changeed crooked for the inner core is better to the effect when the outer tube guide, convenient operation, and be difficult for causing the damage to the trachea back wall.

Detailed Description

The utility model is further described with reference to the accompanying drawings and the detailed description below:

as shown in fig. 1, a convenient guiding endotracheal tube, including inner core 1 and the outer tube 3 of establishing each other cover, the part that inner core 1 stretches out outer tube 3 is equipped with guide section 2, guide section 2 includes extension section 21 and first guide head 22, first guide head 22 is located one side setting that extension section 21 kept away from inner core 1, the used material of guide section 2 is medical soft silica gel, the texture is shorter, easily bend, make things convenient for inner core 1 to be external tube 3, and convenient for operation, and be difficult for causing the damage to trachea rear wall, extension section 21 is straight tube-shaped structure, the external diameter of extension section 21 is the same with the diameter of first guide head 22 left end, convenient at last take out inner core 1 from outer tube 3.

As shown in fig. 2, in a first embodiment of the core, the extension segment 21 is integrally formed with the core 1, so that the core 1 and the extension segment 21 have greater strength and are not easy to be separated.

As shown in figures 3-4, the second embodiment of the inner core is that the first guide head 22 is connected with the inner core 1, the extension section 21 is of a flat plate structure after being unfolded, the extension section 21 is wound on the periphery of one side, close to the first guide head 22, of the inner core 1 and then is bonded with two ends of the inner core through glue, the extension section 21 is tightly matched with the inner core 1, the extension section 21 under the structure can be detached, the extension sections 21 with different sizes and lengths can be replaced, and the hand feeling when different doctors are opposite to the tubes is met.

Fig. 5 to 6 show a third embodiment of the inner core, wherein a second guide head 25 having the same size as the first guide head 22 is disposed at one end of the inner core 1 extending out of the outer tube 3, a groove 24 for accommodating the second guide head is disposed at one end of the extension section 21 close to the inner core 1, the second guide head 25 is accommodated in the groove 2, an injection hole 23 is disposed on the extension section 21, the injection hole 23 extends to the groove 24, a gap is formed between the second guide head 25 and the groove 24, and a syringe penetrates through the injection hole 23 and injects glue into the gap between the second guide head 25 and the groove 24 for fixing the second guide head 25 and the extension section 21.
