Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an air outlet nozzle for supporting a hydrogen-oxygen ventilator. Background Art

[0002] A hydrogen-oxygen ventilator, also known as a hydrogen-oxygen machine, is a device that can produce and output a high-concentration hydrogen-oxygen mixed gas meeting the human inhalation standard. It uses advanced technology to mix oxygen and hydrogen. When people breathe, the mixed gas enters the lungs, and through the gas exchange process, it provides the oxygen required by the cells in the body. The air outlet nozzle used in conjunction with it, as a connecting component between the ventilator and the patient, directly affects the gas delivery effect and the patient's use experience.

[0003] When connecting the existing air outlet nozzle to a hydrogen-oxygen ventilator, screws, nuts or other fasteners are often required for fixation. This not only increases the complexity of the connection steps but also prolongs the connection time, reducing work efficiency. Especially in emergency situations, this cumbersome connection method may delay precious treatment time. Due to the lack of a quick connection and disassembly function for the air outlet nozzle, when equipment maintenance or replacement is needed, tools are often required for disassembly, which not only increases the complexity of the operation but also may cause unnecessary damage to the air outlet nozzle, increasing the maintenance cost.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-5 , the technical solution provided in this embodiment is as follows:

[0027] An air outlet nozzle for supporting a hydrogen-oxygen ventilator includes an air outlet nozzle main body 1, a quick-release mechanism 2 and a sealing mechanism 5. The air outlet nozzle main body 1 is connected to the hydrogen-oxygen ventilator through the quick-release mechanism 2. The quick-release mechanism 2 includes a card slot 201, a connecting pipe 202, a mounting hole 203, a quick-release pin 204, a quick connector 205 and a return spring 206. The card slot 201 is opened on the outer side of the air outlet nozzle main body 1. The connecting pipe 202 is arranged on the outer side of the air outlet nozzle main body 1. The mounting hole 203 is opened at the top of the connecting pipe 202. The quick-release pin 204 is movably installed in the inner cavity of the mounting hole 203. The quick connector 205 and the return spring 206 are both sleeved on the outer side of the connecting pipe 202.

[0028] Please refer to Figures 1-5, there is a cavity 3 between the quick connector 205 and the connecting pipe 202. The number of cavities 3 is two, and the cavity 3 at the bottom is slightly larger than that at the top. The return spring 206 is movably installed in the cavity 3 at the bottom. The number of the card slots 201, the mounting holes 203 and the quick-release pins 204 is the same, all being several. The shape of the quick-release pin 204 is spherical. A connection hole 4 is opened at the bottom of the connecting pipe 202. The diameter of the connection hole 4 is slightly larger than the inner diameter of the connecting pipe 202, and the inner wall of the connection hole 4 is provided with threads.

[0029] Specifically, the gas outlet nozzle body 1 serves as the main channel for gas output, ensuring that the hydrogen-oxygen mixed gas can be stably and efficiently delivered to the patient. The card slot 201 is used to accommodate the quick-release pin 204, and the mounting hole 203 is used to install the quick-release pin 204 to achieve the function of quick disassembly. Through the spherical design of the quick-release pin 204, it is convenient to quickly insert and pull out, realizing the quick connection and disassembly of the gas outlet nozzle. Through the setting of the quick connector 205, the return spring 206 can be compressed. Through the setting of the return spring 206, it can ensure that the quick-release pin 204 can automatically return to its original position, improving the use efficiency. Through the setting of the quick-release mechanism 2, the connection between the gas outlet nozzle and the hydrogen-oxygen ventilator is made faster and more convenient, improving the use efficiency, and at the same time facilitating maintenance and replacement. Through the setting of the cavity 3, a accommodation space is provided for the quick-release pin 204 and the return spring 206 to ensure their normal operation. The connection hole 4 serves as the main channel for the connection between the gas outlet nozzle body 1 and the hydrogen-oxygen ventilator to ensure the smooth flow of gas.

[0030] Embodiment 2:

[0031] Please refer to Figure 3 and Figure 5 , a sealing mechanism 5 is arranged on the connecting pipe 202. The sealing mechanism 5 includes a first mounting groove 501, a first sealing ring 502, a second mounting groove 503, a second sealing ring 504, a third mounting groove 505 and a third sealing ring 506. The first mounting groove 501 is opened on the inner wall of the connection hole 4, and the first sealing ring 502 is arranged inside the first mounting groove 501. The second mounting groove 503 is opened on the inner wall of the connecting pipe 202, and the second sealing ring 504 is arranged inside the second mounting groove 503. The third mounting groove 505 is opened on the outer side of the connecting pipe 202. The number of the third mounting grooves 505 is two, and they are respectively located on the upper and lower sides of the mounting hole 203. The third sealing ring 506 is arranged inside the third mounting groove 505.

[0032] Specifically, through the settings of the first installation groove 501 and the first sealing ring 502, the sealing performance at the connection between the quick-release mechanism 2 and the hydrogen-oxygen ventilator can be ensured, preventing gas leakage. Through the settings of the second installation groove 503 and the second sealing ring 504, the sealing effect at the connection between the air outlet nozzle body 1 and the quick-release mechanism 2 can be enhanced, ensuring that gas does not leak from this location. Through the settings of the third installation groove 505 and the third sealing ring 506, the sealing performance between the quick connector 205 and the connecting pipe 202 can be guaranteed, preventing gas leakage at the connection.

[0033] Working principle: First, the air outlet nozzle body 1, as the core part of gas transmission, is designed to ensure that the hydrogen-oxygen mixed gas can flow stably and efficiently to the patient. On the outer side of the air outlet nozzle body 1, a quick-release mechanism 2 is provided, which makes the connection between the air outlet nozzle and the hydrogen-oxygen ventilator fast and convenient. When it is necessary to connect to the hydrogen-oxygen ventilator, push the quick connector 205, so that the return spring 206 is compressed. At this time, the quick-release pin 204 can be disengaged from the card slot 201, allowing the air outlet nozzle to be connected to the hydrogen-oxygen ventilator. When the connection is in place, the quick connector 205 is no longer compressed, and the return spring 206 releases its elastic potential energy, pushing the quick-release pin 204 back into the card slot 201, thus locking the connection between the air outlet nozzle and the hydrogen-oxygen ventilator. Through the sealing mechanism 5, the sealing performance of the gas during transmission is ensured. The sealing rings are installed at different positions to ensure the sealing performance at the connection between the air outlet nozzle and the hydrogen-oxygen ventilator, at the connection between the air outlet nozzle body 1 and the quick-release mechanism 2, and at the connection between the quick connector 205 and the connecting pipe 202, preventing gas leakage at these key positions.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
