Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Example (b):

referring to fig. 1-5, a trachea cannula with a fixing device comprises a soft gasket 1 which can be attached to the lip of a patient, wherein the soft gasket 1 is provided with a through hole through which an air supply tube cannula can penetrate along the thickness direction; a hard block 2 is fixed inside the soft gasket 1, and a through hole 3 communicated with the through hole is formed in the position, corresponding to the through hole, of the hard block 2; the soft pad 1 is provided with a tether 4.

The insertion step of the tracheal cannula comprises the following steps: inserting the inserting end of the trachea cannula along one end of the through hole of the soft gasket 1, and extending out of the through hole 3 of the hard block 2 and the other end of the through hole of the soft gasket 1; then, the insertion end of the tracheal cannula extending out of the soft pad 1 is inserted into the trachea from the mouth of the patient, at this time, the soft pad 1 is attached to the lip of the patient, the tether 4 is passed around the neck of the patient, and the soft pad 1 positioned outside the mouth of the patient is fixed by the tether 4.

In this embodiment, the soft pad 1 is attached to the lip of the patient, and the soft pad 1 is fixed by the tether 4 wound around the neck of the patient, so that the operation is convenient; the dental pad is not needed in the tracheal intubation fixing process, the problems that a patient feels fidgety when using the dental pad and is easy to push out the dental pad by a tongue are solved, the oral cavity is more favorably cleaned, and the probability of oral ulcer and VAP is reduced; simultaneously, hard piece 2 is by the cladding in soft gasket 1 is inside, can avoid the problem that the patient bitten trachea cannula, thereby can also avoid hard piece 2 directly to cause the problem that the sore is pressed to patient's lip production easily with the contact of patient's lip.

The soft gasket 1 in the embodiment can be made of flexible rubber or medical silica gel, so that the lip skin of a patient is not easily crushed, and mechanical pressure sores are reduced; the hard block 2 can be made of hard metal, alloy, plastic and the like, and is generally made of light materials, so that the problem that the hard block 2 is too heavy to adapt to a patient is solved, and the comfort level of the lips of the patient is improved.

The hard block and the soft gasket are provided with a sputum suction hole 14 for the penetration of a sputum suction pipe at a position close to the tracheal cannula, so that the sputum suction hole 14 can be conveniently inserted into the sputum suction pipe to timely drain the effusion such as sputum of the oral cavity and the throat of a patient.

The inner wall of the through hole 3 in the embodiment is provided with a spring piece 5, one end of the spring piece 5 is fixed on the inner wall of the through hole 3, and the other end is a free end; the inner wall of the perforation 3 corresponding to the free end of the spring leaf 5 is provided with a threaded hole along the radial direction of the perforation 3, a screw rod 6 matched with the threaded hole is arranged in the threaded hole, the end of the screw rod 6 close to the free end of the spring leaf 5 is abutted against the spring leaf 5, and the end of the screw rod 6 far away from the free end of the spring leaf 5 extends out of the soft gasket 1 and is coaxially fixed with a knob 7. After the position of the tracheal cannula is determined, the tracheal cannula is inserted into the trachea at the moment, the screw 6 is controlled to extend by rotating the knob 7 on the screw 6, the spring piece 5 is moved and is abutted to the outer wall of the tracheal cannula, the tube section of the tracheal cannula in contact with the spring piece 5 is fixed in the through hole 3, the tracheal cannula is stably fixed, and the problem that unplanned tube drawing is easily caused is solved. The spring piece 5 is an arc-shaped piece, the inner wall of the arc-shaped piece can be attached to the outer wall of the tracheal cannula, the problem that the tracheal cannula is closed by the spring piece 5 and the inner wall of the through hole 3 in the process that the spring piece 5 abuts against the outer wall of the tracheal cannula cannot occur, and the normal passage of the tracheal cannula is guaranteed; in this embodiment, the spring piece 5 is an arc piece arranged along the inner wall of the through hole 3 in the circumferential direction, so that the problem that the tracheal cannula is blocked by the spring piece 5 and is not easy to penetrate out when being inserted into the through hole 3 is avoided.

Soft gasket 1 is materials such as flexible silica gel or rubber, can make patient's lip better with 1 outer wall laminating of soft gasket, reduces the uncomfortable sense of patient's lip. Soft gasket 1 both sides are provided with the locating hole 8 that can supply tether 4 to pass along length direction, through tying two tether 4's end respectively on two locating holes 8 that correspond, then tie a knot with two tether 4's another end behind the patient's neck, realize soft gasket 1's quick fixed, convenient operation.

The section of the tracheal cannula, which is in contact with the inner wall of the through hole 3 of the hard block 2, is a hard thickened section, and scales 9 are arranged on the hard thickened section, so that the insertion depth of the tracheal cannula can be determined by observing the positions of the scales 9 corresponding to the ends of the soft gaskets 1 outside the oral cavity while the tracheal cannula is further prevented from being bitten, and the tracheal cannula can be accurately inserted into the corresponding positions by medical staff; in this embodiment, the outer wall of the hard thickened section is also provided with a soft layer, and the soft layer and the soft gasket 1 can be integrally formed; when preventing that the patient from clenching the trachea cannula, also increased the comfort level when stereoplasm thickening section and patient's lip contact, prevent that lip from being worn and torn or producing and press the sore.

The trachea cannula is a three-cavity catheter, the three-cavity catheter comprises a main pipe 10, a subglottal suction pipe 11 and an inflation and deflation catheter 12, an air bag 13 is arranged on the outer wall of the end close to the insertion end of the trachea cannula, and the air bag 13 is communicated with the inflation and deflation catheter 12 of the three-cavity catheter. Trachea cannula in this embodiment is three chamber pipes, and gasbag 13 and the inflation and deflation pipe 12 intercommunication of three chamber pipes inflate the gasbag 13 of trachea cannula front end through inflating and deflating pipe 12, firstly can prevent that the outside air from passing through the mouth portion and entering the trachea, secondly can further fix trachea cannula, guarantees that trachea cannula working process is stable, is difficult for producing the problem of taking off the pipe. Meanwhile, the inner wall of the main tube 10 of the tracheal cannula is smooth or is provided with a smooth coating, so that sputum is not easy to attach, and the problem of blockage of the tracheal cannula due to formation of sputum scabs is avoided.
