[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example: Please refer to Figure 1-4 To address the issue of different tracheal tube sizes between adults and children, multiple tracheostomy tubes of various diameters need to be prepared in the emergency room. This increases the difficulty for medical staff in managing the inventory of tracheostomy tubes. In emergencies, medical staff also need to select the appropriate size tracheostomy tube from a large number of available sizes. Furthermore, after the tube is inserted into the trachea, the ventilation port of the tracheostomy tube needs to be connected to a separate air supply device to inflate the cuff, which affects the efficiency of rescue efforts.

[0026] A disposable emergency tracheotomy device includes a middle tracheal tube 1, and a tail tracheal tube 2 is provided at the lower end of the middle tracheal tube 1.

[0027] Specifically, the tail endotracheal tube 2 has a conical structure, and the upper diameter of the tail endotracheal tube 2 is larger than the lower diameter of the tail endotracheal tube 2.

[0028] It should be noted that in actual production, the middle endotracheal tube 1 and the tail endotracheal tube 2 are slightly curved as a whole to meet the physiological structure of the human body. For details, please refer to the extended tracheostomy tube produced by Henan Bocheng Medical Instrument Co., Ltd. Since it is existing technology, it is not shown in the figure. The purpose of the tapered structure of the tail endotracheal tube 2 is to meet the needs of different patients with different tracheal sizes.

[0029] Specifically, a front airbag 3 is fixedly fitted on the upper part of the outer wall of the tail endotracheal tube 2, and a rear airbag 4 is fixedly fitted on the outer wall of the tail endotracheal tube 2 and below the front airbag 3. The outer diameter of the rear airbag 4 is smaller than that of the front airbag 3.

[0030] Specifically, a front tube 5 is inserted into the middle endotracheal tube 1. The front tube 5 is fixedly attached to the inner wall of the middle endotracheal tube 1 and the tail endotracheal tube 2, and the lower end of the front tube 5 is inserted into the tail endotracheal tube 2 and communicates with the front airbag 3.

[0031] Specifically, a rear tube 6 is inserted into the middle endotracheal tube 1. The rear tube 6 is fixedly attached to the inner wall of the middle endotracheal tube 1 and the tail endotracheal tube 2. The lower end of the rear tube 6 is inserted into the tail endotracheal tube 2 and is connected to the rear airbag 4. An air cylinder 7 is installed at the upper end of both the front tube 5 and the rear tube 6. An air supply structure is provided on the air cylinder 7.

[0032] It should be noted that, through the operation of the air supply structure of the front end pipe 5, air can enter the front end airbag 3 through the air cylinder 7 and the front end pipe 5, causing the front end airbag 3 to inflate. Through the operation of the air supply structure of the rear end pipe 6, air can enter the rear end airbag 4 through the air cylinder 7 and the rear end pipe 6, causing the rear end airbag 4 to inflate. When the front end airbag 3 and the rear end airbag 4 are fully inflated, the outer diameter of the rear end airbag 4 is smaller than that of the front end airbag 3.

[0033] When a tracheotomy is required for a child, the rear end balloon 4 of the endotracheal tube 2 is inserted into the patient's trachea. The air supply structure of the rear end tube 6 causes the rear end balloon 4 to inflate, so that the rear end balloon 4 fits against the inner wall of the patient's trachea and supports the device.

[0034] When a tracheotomy is required for an adult, the medical staff first cuts the part between the front balloon 3 and the rear balloon 4, that is, cuts the device short, leaving only the part where the front balloon 3 exists. The front balloon 3 part of the tail endotracheal tube 2 is inserted into the patient's trachea. The air supply structure of the front tube 5 works to make the front balloon 3 inflate, so that the front balloon 3 fits against the inner wall of the patient's trachea and supports the device.

[0035] There is no need to prepare multiple tracheostomy tubes of different diameters in the emergency room, which reduces the difficulty for medical staff in managing the inventory of tracheostomy tubes. In emergency situations, medical staff only need to cut the device to match the device to different patients, thus improving the efficiency of rescue.

[0036] Among them, the front airbag 3, the front tube 5 and the air cylinder 7 can be made in the same color, while the rear airbag 4, the rear tube 6 and the air cylinder 7 can all be made in a different color, so that medical staff can distinguish the air cylinder 7 corresponding to the front airbag 3 and the rear airbag 4 as well as the air supply structure.

[0037] Specifically, the air supply structure includes a piston head 701, which is movably attached to the inner wall of the air cylinder 7. A push rod 702 is installed on the piston head 701, which is movably inserted into the air cylinder 7. An air pressure balance port 703 is provided on the air cylinder 7.

[0038] It should be noted that, in the initial state, the piston head 701 is located at one end of the air cylinder 7, and there is a certain amount of air in the air cylinder 7 and the trachea. At this time, the front airbag 3 and the rear airbag 4 are not inflated. When the air supply structure corresponding to the front airbag 3 or the rear airbag 4 is working, medical personnel can push the push rod 702 on the corresponding air cylinder 7 to move the piston head 701 within the push rod 702, pushing the air in the air cylinder 7 into the corresponding front airbag 3 or the rear airbag 4 for inflation. When it is necessary to withdraw the air from the front airbag 3 or the rear airbag 4, the push rod 702 can be pulled in the opposite direction. The air pressure balance port 703 is used to balance the pressure difference caused by the movement of the piston head 701 within the air cylinder 7, ensuring the smooth movement of the piston head 701. Through the setting of the air supply structure, medical personnel do not need to prepare air supply equipment separately, thus improving rescue efficiency.

[0039] Specifically, a fixing structure is installed on the outer wall of the middle endotracheal tube 1; the fixing structure includes a connecting piece 8, which is fixedly fitted onto the outer wall of the middle endotracheal tube 1. Four connecting straps 9 are provided on the upper wall of the connecting piece 8, which are symmetrically arranged in pairs, and each of the four connecting straps 9 has a passage opening 10.

[0040] It should be noted that during use, the connecting piece 8 and the four connecting straps 9 are attached to the patient's neck. The through-holes 10 on the connecting straps 9 are used to connect the straps, so that the device is fixed to the patient's neck. By setting four connecting straps 9, when medical staff clean the skin below the patient's connecting straps 9, they can symmetrically lift one pair of connecting straps 9 on both sides, while the other pair remains fixed to the patient's neck. Then the two are alternated to ensure the stability of the device while disinfecting the skin.

[0041] Specifically, a retractable hose 11 is provided at the upper end of the middle endotracheal tube 1, and a connector 12 is provided at one end of the retractable hose 11.

[0042] It should be noted that connector 12 is used to connect to the ventilator, and the retractable hose 11 can be bent to increase the flexibility of the device;

[0043] Specifically, the tail end endotracheal tube 2, the retractable flexible tube 11, and the middle end endotracheal tube 1 are integrated into one structure;

[0044] Specifically, a filter screen 704 is fixedly installed on the inner wall of the air cylinder 7 at a location corresponding to the air pressure balance port 703, for filtering out dust, particles and other impurities in the air entering the air cylinder 7 from the outside through the air pressure balance port 703.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
