Description

Technical Field

[0001] This invention patent relates to a tracheal intubation with puncture and fixation functions, and particularly to a tracheal intubation. Background Art

[0002] For currently commercially available tracheal intubations for experimental animals, during the experiment, it is necessary to first make an inverted "T" - shaped incision, then insert a "Y" - shaped tracheal fork, and then fix it with cotton thread. The operation is cumbersome and easily leads to excessive bleeding flowing back into the lungs, causing asphyxia. Summary of the Invention

[0003] The purpose of the present invention is to design a tracheal intubation with puncture and fixation functions to overcome the deficiencies of the prior art.

[0004] This kind of tracheal intubation includes a main tube, a conical inner plug, a side tube, and a trachea fixation clip structure.

[0005] Among them, internal thread structures are provided at both ends of the main tube, an external thread structure is provided on the inner plug, and a push - pull rod is provided on the inner plug to control the coupling or separation of the threads at the upper and lower ends of the main tube. A sunken ventilation groove is provided on the outer surface of the inner plug, and a separable sealing cap is provided at the upper end of the main tube.

[0006] Among them, the side tube communicates with the main tube in a branched shape, and a fin - like protrusion is provided below the bifurcation of the main tube and the side tube.

[0007] Among them, the upper end of the trachea fixation clip is coupled and fixed to the fin - like protrusion of the main tube through a spring piece, in the shape of a clip. The lower end of the trachea fixation clip is arc - shaped and is separably coupled to the outer wall of the main tube.

[0008] Among them, the trachea fixation clip is an adjustable clip that clamps and fixes the tracheal wall outside the main tube.

[0009] Preferably: The tracheal intubation of the present invention is provided with a conical inner plug structure, which is beneficial for directly inserting into the trachea from the tracheal soft tissue; the tracheal intubation of the present invention is provided with a trachea fixation clip, which is beneficial for directly clamping and fixing the trachea to prevent the trachea clip from slipping off.

[0010] The beneficial effects of the present invention are: easy intubation operation, reducing the risk of asphyxia caused by excessive bleeding flowing back into the lungs through the incision, reducing the operation of fixing with cotton thread, and preventing the tracheal intubation from slipping off.

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] As shown in the figure, a tracheal intubation with puncture and fixation includes a main tube 1, a side tube 2, a conical inner plug 3 and a tracheal fixation clip 13. A separable airtight cap 8 for closing the upper end of the main tube is provided at the upper end of the main tube 1. An external thread 5 is provided on the conical inner plug 3. The conical inner plug 3 is controlled by a push rod 6 to be coupled or separated from the upper thread 7 or the lower thread 9 of the main tube. An inward groove ventilation hole 4 is provided on the surface of the conical inner plug 3. The side tube 2 is branched and communicated with the main tube 1. A hose is connected to the end of the side tube 2 to a flow transducer. A fin-shaped protrusion 12 is provided below the bifurcation of the main tube 1 and the side tube 2. The lower end of the tracheal fixation clip 13 is arc-shaped and can be coupled and clamped to the outside of the main tube. The upper end 11 of the tracheal fixation clip is coupled and fixed to the fin-shaped protrusion 12 through a spring piece 10. The tracheal fixation clip 13 is an adjustable opening and closing clip for clamping and fixing the tracheal wall to the outside of the main tube.

[0016] The usage method of the present invention is to control the push rod 6 so that the conical inner plug 3 is thread-coupled with the lower thread 9 of the main tube, exposing the conical tip of the conical inner plug 3. Insert it into the trachea through the soft tissue above the thyroid cartilage. Press open the tracheal fixation clip 13 and continue to insert it into the trachea in the direction of the lung until the tracheal insertion opening covers the area covered by the lower end of the tracheal fixation clip. Release the tracheal fixation clip 13 to clamp the tracheal wall.

[0017] The push rod 6 is retracted to be coupled with the upper thread 7 of the main tube 1, and the separable airtight cap 8 is sealed. Respiratory gas flows in and out through the side tube 2. The side tube 2 is connected to a flow transducer through a hose, facilitating the collection of the flow rate of the respiratory airflow.
