Description

Technical Field

[0001] The present invention belongs to the field of medical related technology, and more specifically, particularly relates to an oral endotracheal intubation auxiliary device and a method thereof. Background Art

[0002] In medicine, oral endotracheal intubation is a common medical treatment method, which is mainly used to establish an artificial airway and keep the airway open. During oral endotracheal intubation, auxiliary devices are usually required during and after intubation to maintain the stability of the trachea.

[0003] An orotracheal intubation auxiliary device and method thereof also have the following defects: 1. When patients use auxiliary devices to fix their trachea, they need to be fixed for a long time until they recover. During this period, they need to take oral care to prevent oral infection. Oral cleaning is done manually on the market. During this process, the patient's mouth needs to be opened by hand. This method is cumbersome and will damage the oral mucosa, increasing the risk of infection. 2. In the prior art, the pipeline is installed in an auxiliary device and then passed into the patient's body. During the intubation, it is inevitable that the patient will bite the tube. Once the patient bites the tube, it will cause tracheal obstruction, which will endanger the patient's life.

[0037] A method for using an orotracheal intubation assisting device comprises the following steps: Step 1: fix the arc-shaped soft strip 1 to the upper part of the patient's lips through the fixing unit 10, wherein the pad 1 6 is closely attached to the upper part of the patient's lips, and the pad 2 905 is closely attached to the patient's cheek, and the fixing unit 10 is used to adjust the tightness of the device when it is fixed to the patient's face; First, adjust the fixing unit 10 to the maximum limit, put the device on the patient's face, then align the arc-shaped soft strip 1 with the patient's upper lip, and press the knob in the fixing unit 10. At this time, the knob will press against the rotating rod 1002 to disengage the triangular block 1004 from the engaging state with the triangular groove opened on the surface of the partition 1003. Turn the knob to allow the nylon belt 1008 to be wound around the rotating rod 1002, wherein the bearing 1005 allows the rotation of the rotating rod 1002 to be smoother. When the nylon belt 1008 is adjusted to a tightness suitable for the patient, release the button, and the spring 1007 will press against the bearing 1005, so that the triangular block 1004 is re-engaged in the triangular groove opened on the partition 1003.

[0038] Step 2: adjust the slider 1 3 to slide on the ear block 2, so as to install the slightly expanded unit 8 in the patient's cavity, insert the trachea through the auxiliary tube sleeve 801 in the slightly expanded unit 8, and then fix the trachea with the bandage 803; In step 1, when the adjustment is not complete, the slider 1 3 is slid in the ear block 2, the slightly expanded unit 8 is adjusted to the position of the patient's mouth, and the auxiliary tube sleeve 801 is inserted into the patient's oral cavity. The semi-open auxiliary tube sleeve 801 can be used to install tracheas of different thicknesses, wherein the bandage 803 and the anti-sliding block 804 can fix the trachea to prevent sliding; At the same time, the lower tooth pad sleeve 811 and the upper tooth pad sleeve 812 are respectively installed on the upper and lower teeth of the patient. When the patient's mouth needs to be cleaned, the air outlet end of the airbag 11 is first connected to the air nozzle 1 805, and gas is injected. The pneumatic plug rod 1 808 and the pneumatic plug rod 2 809 slide toward the two ends of the cylindrical shell 802 respectively, so that the lower tooth pad sleeve 811 and the upper tooth pad sleeve 812 lift the upper and lower teeth. At this time, the nurse can easily clean the patient's mouth. At the same time, the upper tooth pad sleeve 812 and the lower tooth pad sleeve 811 lift the teeth to prevent the patient from biting the auxiliary tube sleeve 801 and indirectly biting the pipe, causing the pipe to be blocked.

[0039] Step 3: The adjusting unit 9 is adjusted by the airbag 11, so that the slightly-opening unit 8 can be slightly adjusted left and right; In step two, the installation and fixation of the pipeline is completed. At this time, the air outlet end of the airbag 11 is installed in the air nozzle 2 904, and gas is injected or sucked out into the air cavity 903 inside the mounting block 1 902, so that the pneumatic slide rod 901 slides in the air cavity 903, so that the arc-shaped soft strip 1 moves left and right, and the position of the pipeline in the oral cavity can be indirectly adjusted, so that the patient is in a comfortable pipeline deflection state.
