Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent ventilators, and in particular relates to an intelligent ventilator air circuit system with air-oxygen mixing. Background Art

[0002] Based on the usage method and usage scenario of the smart ventilator, a variety of situations may be encountered during use, but not limited to the one mentioned below. In particular, when a home smart ventilator is used, it assists the wearer in breathing through an air pump and a tube, and is worn through an oral and nasal mask or tracheal insertion.

[0003] Existing smart ventilators may not operate normally during use due to damage to the air pump or a short circuit in the internal structure. If the person is sleeping at this time, wearing a mask will affect the wearer's breathing and there may be a risk of suffocation. Moreover, when wearing a ventilator for a long time, the dry air may cause nasal bleeding and other conditions.

[0004] Based on the above-mentioned situation, we found that it is difficult for existing intelligent ventilators to avoid the above problems at the same time. Therefore, we proposed a ventilator airway system with a backup auxiliary breathing structure and the ability to humidify the breathing process. Summary of the Invention

The left side of the collecting wide tube 3 is bolted with a humidity sensor 10. By setting the tube clamp 9, the rear section tube 4 can be easily connected to the body shell 1, making the structure more reasonable. The set humidity sensor 10 is used to monitor the humidity of the exhaled gas of the wearer so as to humidify when the humidity is too low.

[0042] like Figure 2As shown, a cooling fan 11 is bolted to the right side of the body shell 1, and an oxygen mixer structure 12 is bolted to the bottom inside the body shell 1. By setting the cooling fan 11, the structure inside the body shell 1 can be easily heated, and the oxygen mixer structure 12 is set to perform air mixing.

[0045] like Figure 4 As shown, both sides of the surface of the sleeve 501 are bolted with a fixing ring 17, and the outer side of the sleeve 501 is rotatably connected with an inner screw sleeve 18, the inner side of the rear inner screw sleeve 18 is threadedly connected to the rear section pipe 4, and the inner side of the front inner screw sleeve 18 is threadedly connected to the front section pipe 6.

By arranging the electric control valve 19 in coordination with the water storage tank 20, humidification water can be pre-stored inside the water storage tank 20. When the respiratory gas is too dry, the electric control valve 19 opens, allowing the internal humidification water to enter the internal part of the sleeve 501 and soak the humidification cotton 502 to humidify the respiratory gas.

[0047] like Figure 5As shown, the outer side of the top of the water storage tank 20 is threadedly connected to a top cover 21, and the bottom of the top cover 21 is bolted to a sealing gasket 22.

[0048] Brief description of the usage process: When in use, the user completes the wearing process by wearing the oral and nasal mask 7. During normal operation, the air pump 201 is started, and the two branches of the branch pipe 202 are used to replace the inhalation and exhalation pipelines respectively. The inhalation valve 203 and the flow valve 204 are used to cooperate with the inhalation operation and adjust the gas flow. The exhalation valve 205 and the pressure regulating valve 206 are used to cooperate with the exhalation action and adjust the gas pressure. When the air pump 201 or other structures have problems and cause blockage or cannot operate normally, because two sets of air path components 2 are provided, Therefore, the air pump 201 of another set of air path components 2 is started to replace the operation to avoid the risk of suffocation caused by structural damage. When the gas passes through the functional component 5, it will be humidified due to the moisture in the humidifying cotton 502 to prevent the gas from being too dry. The moisture in the user's exhaled gas will also partially penetrate into the humidifying cotton 502 to continue humidification. The exhaled gas is monitored by the humidity sensor 10 when it is recovered. If the humidity is low, it means that the humidifying cotton 502 has too little moisture. Therefore, the electric control valve 19 is opened, and the humidification water stored in the water storage tank 20 will soak the humidifying cotton 502 to increase the humidity.

[0049] Example 2:

[0050] refer to Figure 1-7 , including a body shell 1, an air path component 2 is bolted to the bottom of the inner wall of the body shell 1, and an air intake component 8 is provided on the rear side of the body shell 1. By providing the air intake component 8, the gas entering the inside of the device can be filtered to prevent larger impurities from entering the structure and causing blockage.

[0051] like Figure 7 As shown, the air intake assembly 8 includes an outer frame 801, the inner side of the outer frame 801 is bolted to a limit frame 802, the inner side of the limit frame 802 is clamped with a mesh frame 803, the inner side of the mesh frame 803 is bolted to a coarse screen 804, the top of the mesh frame 803 is bolted to a cross frame 805, the bottom of the cross frame 805 is in contact with the top of the outer frame 801, and by arranging the outer frame 801 and the limit frame 802 to cooperate, it is convenient to connect the mesh frame 803 through the cross frame 805, so as to install the inner side of the outer frame 801 and the coarse screen 804, which can facilitate filtering the air intake position and filter out larger impurities.

[0052] like Figure 6 and Figure 7As shown, the rear side of the body shell 1 is bolted with an inner frame 23, and the inner frame 23 is sleeved on the inner side of the outer frame 801. The inner side of the outer frame 801 is provided with a connecting screw 24, and the outer side of the connecting screw 24 is threadedly connected to the inner frame 23. By providing the inner frame 23, it is convenient to sleeve the outer frame 801 on the outer side of the inner frame 23 for installation, and the inner frame 23 and the outer frame 801 are fixed by passing the connecting screw 24 through the outer frame 801 and screwing it into the inner side of the inner frame 23.

[0053] Brief description of the usage process: When in use, the gas is initially filtered through the coarse screen 804 to filter out larger impurities and flocs to avoid blockage or choking by the user. When the coarse screen 804 needs to be cleaned, the outer frame 801 can be removed from the outer frame 801 through the cross frame 805 to remove the coarse screen 804 for replacement or cleaning. When the outer frame 801 needs to be installed or removed, the connecting screw 24 can be tightened or unscrewed to complete the installation or disassembly between the inner frame 23 and the outer frame 801.
