Referring to fig. 1-5, as an embodiment of the present utility model, there is provided an tracheal cannula assembly, comprising an outer tube sleeve 1 and an inner tube sleeve 2, wherein the outer tube sleeve 1 comprises an outer tube 11 and a positioning disk 12 arranged at one end of the outer tube 11, the inner tube sleeve 2 comprises an inner tube 21 and a socket joint 22 rotatably arranged at one end of the inner tube 21, the positioning disk 12 is provided with a plurality of protruding parts 13 corresponding to the periphery of the mouth of the outer tube 11, the peripheral edge of the socket joint 22 is provided with a plurality of notch parts 23, the protruding parts 13 are in one-to-one correspondence with the notch parts 23, so as to realize the assembly limit of the socket joint 22 and the positioning disk 12, thereby limiting the inner tube 21 inside the outer tube 11.

Above-mentioned technical scheme is through a plurality of bellying 13 and the cooperation of notch 23 one-to-one to realize that the cover connects 22 and positioning disk 12 stable assembly is spacing, thereby with inside outer tube 11 is stable spacing with inner tube 21, stability is higher, thereby prevent because of the patient takes place not hard up outside the outer tube external member 1 that drops because of patient's long cough or violent cough makes inner tube external member 2 take place, guarantee the medical treatment after the tracheotomy operation and nursing activity's normal clear, and then guarantee patient's normal breathing and life safety.

In this embodiment, the outer tube 11 has various sizes such as 10mm, 9mm and 6mm, and is suitable for patients of different groups such as male, female and children.

In this embodiment, the number of the protruding portions 13 and the number of the notch portions 23 are three, and the three protruding portions 13 are uniformly arranged on the periphery of the positioning disk 12 corresponding to the pipe orifice of the outer pipe 11, and the three notch portions 23 are uniformly arranged on the circumferential edge of the socket 22, so that the socket 22 is ensured to be stressed more uniformly in all directions on the positioning disk 12, and the probability that the inner pipe sleeve 2 loosens and falls out of the outer pipe sleeve 1 is reduced. Of course, any number of the protruding portions 13 and the notched portions 23 may be used, for example, four protruding portions 13 and four notched portions 23, respectively.

In this embodiment, the protruding portion 13 is in a thumbtack shape, and the notch portion 23 is an arc notch corresponding to the thumbtack-shaped protruding portion 13, so that the protruding portion 13 can stably block and limit the socket 22.

In this embodiment, the positioning plate 12 is an oval positioning plate, two ends of the long axis direction of the positioning plate are respectively provided with a positioning hole 14, and the positioning holes 14 are threaded to form positioning fit with the neck incision of the human body, so that the utility model can be stably fixed on the neck incision of the human body, and the operation is convenient and safe to carry out.

In this embodiment, outer tube external member 1 and interior tube external member 2 are the metal external member, guarantee that its stability of assembling each other is better, difficult emergence deformation avoids causing the shutoff to patient's tracheal inner wall, influences patient's breathing.

Of course, because the neck and the thickness degree of the trachea of the patients with different body types and different age groups are different, the lengths of the outer tube sleeve 1 and the inner tube sleeve 2 used by the patients are also different according to the thickness degree of the trachea, so the outer tube sleeve 1 and the inner tube sleeve 2 can be also arranged to be capable of synchronously performing telescopic adjustment along the axial direction of the outer tube sleeve 1 and the inner tube sleeve 2, and the higher degree of the application is ensured.

When the general vital sign of the patient is good after operation for a period of time, the open tracheal cannula mouth is considered to be blocked, the mouth and nose breathing function of the patient is recovered, the breathing condition of the patient to be evaluated is still, active and sleeping, and if the mouth and nose breathing is good, the blocked tracheal cannula is pulled out for about 48 hours. Regarding the blocking pipe, the existing mode is more, for example, the pipe orifice on the sleeve joint 22 is blocked by the plasticine, the cotton swab or the paper towel, but the mode is low in tightness, and external impurities and foreign matters are easy to enter the patient body through the pipe orifice, so that the intra-tracheal foreign matters are formed, the patient is difficult to breathe, even the suffocating risk exists, and the great potential safety hazard exists. Therefore, in this embodiment, tracheal cannula subassembly still includes a shutoff lid 4 for to cup joint 22 shutoff, when needs are observed the autonomous respiration condition of patient, with shutoff lid 4 shutoff setting on cup joint 22, this shutoff lid 4 leakproofness is stronger, also can prevent that outside impurity, foreign matter from entering into the patient, guarantee that the patient breathes normally, and then guarantee validity and the security of the stifled pipe after the operation, and shutoff lid 4 carries out reuse for accessible high temperature or soak disinfection, avoids appearing cross infection.

In this embodiment, the plugging cover 4 is a piston on a 20ml syringe, which is common in hospitals, easy to obtain and high in universality.

In this embodiment, the tracheal cannula assembly further comprises a guiding member 3, which includes an arc-shaped rod 32, and a guiding portion 33 and a holding portion 31 located at two ends of the arc-shaped rod 32, wherein the guiding member 3 is used for guiding the outer tube set 1 so as to smoothly insert the outer tube set 1 into a trachea of a patient.

In this embodiment, the arc of the arc rod 32 corresponds to the arc of the outer tube 11, so that the guide member 3 can smoothly extend into the outer tube 11.

In this embodiment, the guiding portion 33 is a conical guiding portion, the end of the conical guiding portion protrudes out of the pipe orifice below the outer pipe 11, the holding portion 31 is a cylindrical holding portion 31, and two ends of the cylindrical holding portion 31 are gradually narrowed toward the middle, so that the holding is more convenient.

The operation flow of this embodiment is as follows:

1. firstly, a guide piece 3 stretches into an outer tube sleeve 1, the tail end of a conical guide part protrudes out of a tube orifice below an outer tube 11, then the outer tube sleeve 1 is guided to be inserted into a trachea of a patient along a neck incision in an inclined manner by 45 degrees, the guide piece 3 is continuously adjusted and corrected in the inserting process, and then the guide piece 3 is taken out, and a positioning disc 12 is fixed at the neck incision;

2. then the inner tube 21 is extended into the outer tube 11, the convex parts 13 are matched with the notch parts 23 in a one-to-one correspondence manner, so that the sleeve joint 22 and the positioning disk 12 are assembled and limited, the inner tube sleeve 2 is stably and limitedly arranged in the outer tube sleeve 1, and a patient can breathe through the tracheal tube assembly;

3. when the respiratory function of the mouth and the nose of a patient needs to be observed, the piston plugging cover 4 is closed on the socket 22, then the patient is observed for at least 48 hours, and after the patient can breathe spontaneously through the mouth and the nose normally, the tracheal cannula component is pulled out.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
