Detailed Description

The utility model will be described in detail below with reference to the following figures: as shown in fig. 1-5, the tracheal intubation device with an adjustable end according to the present invention comprises a tracheal intubation body, wherein a hollow tube 2 with a mesh structure is disposed in front of the tracheal intubation 1, a metal pull ring 3 is fixed to an end of the hollow tube 2 with the mesh structure away from the tracheal intubation 1, an operation portion 4 is disposed behind the hollow tube, a metal inner core 5 penetrating through the tracheal intubation 1 and the hollow tube 2 is disposed inside the tracheal intubation 1, a shallow groove 6 is disposed at a front end of the metal inner core 5, a fastening device 7 for fixing the metal inner core to the tracheal intubation is fixed behind the metal inner core 5, when the metal inner core 5 is pushed forward and contacts the metal pull ring 3, the metal pull ring 3 is embedded in the shallow groove 6 at the front end of the metal inner core 5 and drives the hollow tube 2 with the mesh structure to be pulled forward to achieve a tightening effect, and when the metal pull ring 3 is released, the hollow pipeline 2 of the silk screen structure can keep the original hollow state, so that the hollow pipeline has the characteristic of adjustable thickness, the operation part 4 consists of a handheld handle 8 at the outer side and 2 fixed edges 9 which are concave in the middle of the two sides of the handle 8, the fixed edges 9 are provided with a plurality of symmetrical circular bulges 10, the rear part of the metal inner core 5 is provided with a fixed block 11, a fixed groove 12 which is used by the matched fixed edge is arranged in the fixed block 11, a circular fixed groove 13 which is symmetrical to the circular bulges 10 is arranged in the groove 12, the joint of the trachea cannula 1 and the hollow pipeline 2 of the silk screen structure is provided with 1CM overlapping, the joint of the operation part 5 and the trachea cannula 1 is also provided with 1CM overlapping to ensure that the trachea cannula 1 is not easy to fall off in use, the hollow pipeline 2 of the silk screen structure is arranged at the quarter of the front of the trachea cannula 1, this design has good flexibility and support, the hollow pipe 2 of the wire mesh structure being made of an alloy material.

The specific operation method comprises the following steps:

when the metal inner core is inserted into the hollow pipeline of the memory metal alloy woven wire mesh structure at the front end of the device, the metal pull ring at the front end of the hollow pipeline of the memory metal alloy wire mesh structure is required to be embedded into the shallow groove at the front end of the metal inner core, the metal pull ring can be tightened when the metal inner core is pushed forwards, the hollow pipeline of the alloy mesh wire mesh structure becomes thin correspondingly, and the insertion pipe can pass through the narrow part smoothly. The buckle device of the tail metal inner core: the tracheal intubation device is used for fixing the metal inner core on the tracheal intubation device, so that the metal pull ring at the front end of the hollow pipeline of the memory metal alloy wire mesh structure is the tightest, and the front end of the tracheal intubation device is in the thinnest state; once this trachea cannula device passes through the narrow part of trachea smoothly, accomplishes the trachea cannula and puts into smoothly, unblock afterbody metal inner core buckle fixing device, take out the metal inner core, the hollow pipeline structure that the memory alloy silk of trachea cannula device front end was woven can resume original internal diameter this moment, keeps the air flue to ventilate smoothly.
