Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an integrated high-flow saturation oxygen inhalation device. Background Technology

[0002] An oxygen inhaler, also known as an oxygen delivery device, is a medical device used to precisely measure oxygen flow. Its primary function is to provide a stable flow of oxygen to emergency patients. It is also suitable for chronically hypoxic patients requiring long-term oxygen therapy. This device allows for adjustments to the oxygen delivery rate and concentration based on the patient's specific medical needs, achieving optimal therapeutic effects. Common oxygen delivery methods include buoy-type oxygen delivery, primary oxygen delivery (also known as nasal cannula oxygen delivery), and saturation oxygen delivery (such as high-flow oxygen delivery using an oxygen mask). The choice of method depends on the individual's specific condition, including their required oxygen pressure and flow rate, and whether oxygen therapy needs to be conducted in a closed environment.

[0003] Current oxygen concentrators have limitations in that they cannot be used independently. When users need to use such concentrators, they must be equipped with additional oxygen cylinders, connected to a hospital's central oxygen supply system, or rely on external oxygen supply devices such as home oxygen concentrators. This is particularly inconvenient for patients who need to use them while mobile or outdoors. For example, in emergency rescue scenes or home care environments, the lack of a built-in oxygen source in oxygen concentrators not only increases the complexity of preparation but may also delay the optimal time for treatment.

[0004] In addition, since these oxygen concentrators need to be used in conjunction with external oxygen supply equipment, this places higher demands on the user's operating skills, including correctly connecting the equipment, adjusting the appropriate oxygen flow rate, and ensuring the airtightness of the system. Any negligence may lead to insufficient oxygen supply or other safety hazards. Utility Model Content

[0005] To address the shortcomings of the above-mentioned oxygen inhalation devices, which require the use of an external oxygen source, are not only complicated to operate, but also inconvenient to use on a mobile basis, this utility model provides an integrated, high-flow, and easy-to-operate saturation oxygen inhalation device.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An integrated high-flow saturated oxygen inhalation device includes a housing with an air inlet. Inside, there is an oxygen generator and an oxygen inhalation mechanism. The oxygen inhalation mechanism includes a gas storage tank, the outlet of which is connected to a primary oxygen inhalation pipeline and a saturated oxygen inhalation pipeline. The primary oxygen inhalation pipeline is formed by sequentially connecting a primary flow control switch, a primary flow meter, and a primary oxygen inhalation port. The saturated oxygen inhalation pipeline is formed by sequentially connecting a saturated flow control switch, a saturated oxygen inhalation flow meter, and a saturated oxygen inhalation port. The primary flow control switch, primary flow meter, primary oxygen inhalation port, saturated flow control switch, saturated oxygen inhalation flow meter, and saturated oxygen inhalation port are embedded in the surface of the housing. The outlet of the oxygen generator is connected to the air inlet of the gas storage tank, and the oxygen generator is connected to a switch embedded in the housing.

[0007] The oxygen generator can be a commercially available conventional oxygen generator, such as an electronic oxygen generator, a molecular sieve oxygen generator, a chemical oxygen generator, or an oxygen-enriched membrane oxygen generator. This solution is based on the advantages of molecular sieve oxygen generators, which are safe, convenient, and ready to use immediately, and therefore prefers molecular sieve oxygen generators.

[0008] Furthermore, the switch is a mechanical timer switch. During use, the user can set the duration of oxygen supply according to actual needs, and start the device by rotating or toggling the timer switch to the desired time period. After the set time is reached, the switch will automatically cut off the power and stop the oxygen supply, which not only simplifies the operation process but also ensures the accuracy and safety of the oxygen therapy process.

[0009] Furthermore, the oxygen concentrator's outlet is equipped with a one-way valve, and the oxygen concentrator is also electrically connected to a display screen, which is embedded in the outer casing. The one-way valve prevents oxygen delivered from the oxygen concentrator to the storage tank from flowing back and causing contamination, while the display screen can display relevant parameters of the oxygen concentrator, such as current pressure, temperature, and total usage time.

[0010] Furthermore, the display screen is electrically connected to functional buttons, which are symmetrically arranged below the display screen. There may be one or more functional buttons, and each button can be configured according to actual needs, such as being set to activate the oxygen concentrator's timer function with a single button press, or adjusting the screen brightness, etc.

[0011] Furthermore, the gas storage tank is also connected to a safety valve. The safety valve will automatically open when the pressure in the gas storage tank exceeds the set safety range, releasing excessive pressure to protect the safety of the equipment and the user. It can ensure that the internal pressure of the device is maintained within a safe range under any circumstances, preventing device damage or safety accidents caused by excessive pressure.

[0012] Furthermore, a micro-resistance regulating breathing valve is also provided between the gas storage tank and the saturated oxygen flow switch. The micro-resistance regulating breathing valve allows for more precise control of breathing resistance during oxygen delivery, making oxygen therapy more personalized and comfortable. It not only optimizes oxygen delivery efficiency but also makes patients feel more natural and comfortable during oxygen inhalation. By reducing the work of breathing, it reduces the physical exertion of patients, providing users with the best oxygen therapy experience whether at rest or during activity.

[0013] Furthermore, the outer casing is formed by combining a first chamber and a second chamber. The first chamber houses an oxygen intake mechanism, with a primary flow control switch, a primary flow meter, a saturation flow control switch, and a saturation oxygen intake flow meter embedded in its surface. The primary oxygen intake port and the saturation oxygen intake port are located on the surface of the second chamber, with air inlets connected to the primary flow meter and saturation oxygen intake flow meter respectively via pipes. The second chamber has an air inlet on its side and houses an oxygen generator, with the generator's display screen and switch embedded in the surface of the first chamber. Dividing the outer casing into two chambers, with the first chamber housing the oxygen intake mechanism and control panel, makes operation more centralized and intuitive. The improved oxygen intake port connects to the surface of the second chamber via an internal channel, eliminating the need for external piping. The oxygen generator's display screen and switch are located on the surface of the first chamber, forming a unified operating interface, improving ease of use and the overall neatness of the equipment.

[0014] Furthermore, the primary flow meter and the saturation oxygen flow meter are symmetrically arranged on the left and right sides of the front of the first chamber, with a switch in the middle and a display screen above the switch. A primary flow control switch is located below the primary flow meter, and a saturation oxygen flow control switch is located below the saturation oxygen flow meter. All control components are concentrated on the same panel, forming a unified operating platform. This not only improves the overall aesthetics and saves space but also simplifies the operation process, reduces the possibility of misoperation, and allows users to quickly distinguish between the two different oxygen inhalation modes and operate directly in the corresponding areas, improving convenience and efficiency.

[0015] Furthermore, the first and second compartments can adopt an up-and-down or left-and-right structure. The left-and-right structure is used for installation or use scenarios where height is insufficient. However, based on structural rationality and common usage scenarios, this solution preferably adopts an up-and-down structure. The first and second compartments adopt an up-and-down structure, and a through hole is provided at the connection point. The design of the first and second compartments adopting an up-and-down structure results in a small footprint, a compact and rational layout of internal components, and reduces the need for external piping, enhancing the overall aesthetics and portability of the equipment.

[0016] Furthermore, the second compartment is symmetrically equipped with carrying slots on both sides and casters at the bottom. The design of the carrying slots and casters greatly facilitates the movement and handling of the device. In use, users can easily lift the device for short-distance transport using the carrying slots, or use the casters at the bottom to slide the device freely on a flat surface for convenient long-distance movement, which is convenient for occasions that require frequent adjustments to the device's position or transfer between different scenarios.

[0017] To use, first turn on the switch on the device. The oxygen concentrator will start, and air will enter through the air inlet on the outer casing to begin producing oxygen. The oxygen will then be delivered to the storage tank through the connected pipes. The user can then select the oxygen inhalation mode according to their needs. When using the primary oxygen inhalation mode, first turn on the primary flow control switch, then adjust it to the desired flow rate and confirm the oxygen flow rate using the primary flow meter. Then connect the standard nasal cannula or mask to the primary oxygen inhalation port for oxygen inhalation. When using the saturation oxygen inhalation mode, first turn on the saturation flow control switch, then adjust it to the desired flow rate and confirm the oxygen flow rate using the saturation flow meter. Then connect the standard nasal cannula or mask to the saturation oxygen inhalation port for oxygen inhalation. When the predetermined oxygen therapy time is reached or the patient feels better, first turn off the corresponding primary flow control switch or saturation flow control switch to stop the oxygen supply. Then turn off the switch, disconnect the oxygen concentrator's power supply, and finally disconnect all connections and store the device properly.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This utility model integrates an oxygen generator and an oxygen inhalation mechanism into one unit, eliminating the need for external oxygen supply equipment, simplifying the device's operation, and improving the convenience and flexibility of oxygen supply. It is suitable for emergency rescue or home care. The oxygen generator can be started by turning on a switch, and oxygen is stored in the storage tank. It can also select a single-stage, full-load, or combined oxygen inhalation mode as needed. The operation is simple, and the oxygen flow rate can be adjusted through a flow control switch and a flow meter to achieve precise oxygen supply.

[0019] 2. The mechanical timer switch, safety valve, and micro-resistance regulating breathing valve of this utility model work together to improve the convenience and safety of the device during use. Users can set and automatically control the oxygen supply time through the timer switch to ensure a precise and safe oxygen therapy process. The safety valve can automatically release when the pressure is too high to protect the equipment and the user. The micro-resistance regulating breathing valve optimizes the breathing resistance of oxygen delivery, making the treatment more personalized and comfortable, reducing the user's physical exertion, and providing the best oxygen therapy experience in various conditions.

[0020] 3. The control components of this utility model are concentrated on the surface of the first compartment, forming an intuitive operating interface, reducing the possibility of misoperation and improving ease of use; the design of the first and second compartments with an up-down or left-right structure has a compact and reasonable internal layout, reducing the need for external pipelines and enhancing aesthetics and portability; while the design of the carrying slot and universal wheels facilitates the movement and handling of the equipment, making it suitable for occasions where frequent position adjustments are required.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1: An integrated high-flow saturated oxygen inhalation device includes a housing 1 with an air inlet 11. Inside the housing 1 are an oxygen generator 2 and an oxygen inhalation mechanism 3. The oxygen inhalation mechanism 3 includes a gas storage tank 31, the outlet of which is connected to a primary oxygen inhalation pipeline and a saturated oxygen inhalation pipeline. The primary oxygen inhalation pipeline is formed by sequentially connecting a primary flow control switch 32, a primary flow meter 33, and a primary oxygen inhalation port 34. The saturated oxygen inhalation pipeline is formed by sequentially connecting a saturated flow control switch 35, a saturated oxygen inhalation flow meter 36, and a saturated oxygen inhalation port 37. The primary flow control switch 32, the primary flow meter 33, the primary oxygen inhalation port 34, the saturated flow control switch 35, the saturated oxygen inhalation flow meter 36, and the saturated oxygen inhalation port 37 are embedded in the surface of the housing 1. The outlet of the oxygen generator 2 is connected to the air inlet of the gas storage tank 31, and the oxygen generator 2 is connected to a switch 22, which is embedded in the housing 1.

[0027] The oxygen concentrator uses a molecular sieve type. To use it, first turn on switch 22 on the device. The oxygen concentrator 2 starts, and air enters from the air inlet 11 of the outer casing 1 to begin producing oxygen. The oxygen is then transported to the storage tank 31 through a pipeline. The user then selects the oxygen inhalation mode according to their needs. When using the primary oxygen inhalation mode, first turn on the primary flow control switch 32, then adjust the primary flow control switch 32 to the desired flow rate, and confirm the oxygen flow rate through the primary flow meter 33. Then, connect the standard nasal cannula or mask to the primary oxygen inhalation port 34 for oxygen inhalation. When using the saturation oxygen inhalation mode, first turn on the saturation flow control... After adjusting the saturation flow control switch 35 to the desired flow rate, and verifying the oxygen flow rate through the saturation oxygen flow meter 36, connect the nasal cannula or mask (usually worn) to the saturation oxygen port 37 for oxygen inhalation. When the predetermined oxygen therapy time is reached or the patient feels better, first turn off the corresponding primary flow control switch 32 or saturation flow control switch 35 to stop the oxygen supply. Then turn off switch 22 to disconnect the power to the oxygen generator 2. Finally, disconnect all connections and store the equipment properly. The air inlet 11 is also used for internal heat dissipation. The primary oxygen inhalation mode and the saturation oxygen inhalation mode can be used in combination according to actual usage needs.

[0028] Example 2: Unlike Example 1, the switch 22 is a mechanical timer switch. In use, the user can set the duration of oxygen supply according to actual needs, and start the device by rotating or toggling the timer switch 22 to the desired time period. After the set time is reached, the switch 22 will automatically cut off the power and stop the oxygen supply, which not only simplifies the operation process but also ensures the accuracy and safety of the oxygen therapy process.

[0029] The oxygen concentrator 2 is also equipped with a one-way valve at its outlet, and is electrically connected to a display screen 21, which is embedded in the outer casing 1. The one-way valve prevents oxygen from flowing back into the storage tank and causing contamination, while the display screen 21 displays relevant parameters of the oxygen concentrator 1, such as the current working pressure, operating temperature, and total usage time, for the user's convenience.

[0030] The display screen 21 is also electrically connected to functional buttons, which are symmetrically arranged below the display screen 21 and above the switch 22. There are one or more functional buttons, and each functional button can be set according to actual needs, such as being set to turn on the oxygen concentrator's timer function with one click, or to adjust the screen brightness, etc. The display screen 21 can be electrically connected to the gas storage tank or other components according to actual display needs.

[0031] The gas storage tank 31 is also connected to a safety valve 311. The safety valve 311 will automatically open when the pressure in the gas storage tank 31 exceeds the set safety range to release the excessive pressure, thereby protecting the safety of the equipment and the user. It can ensure that the internal pressure of the device can be maintained within a safe range under any circumstances, preventing damage to the device or safety accidents caused by excessive pressure.

[0032] A micro-resistance regulating breathing valve 38 is also provided between the gas storage tank 31 and the saturated oxygen flow switch 35. The micro-resistance regulating breathing valve 38 allows for more precise control of breathing resistance during oxygen delivery, making oxygen therapy more personalized and comfortable. It not only optimizes oxygen delivery efficiency but also makes patients feel more natural and comfortable during oxygen inhalation. By reducing the work of breathing, it reduces the physical exertion of patients, providing users with the best oxygen therapy experience whether at rest or during activity.

[0033] Example 3: Unlike Example 1, the outer shell 1 is formed by combining a first chamber 12 and a second chamber 13; the first chamber 12 is provided with an oxygen intake mechanism 3, and a primary flow control switch 32, a primary flow meter 33, a saturated oxygen intake control switch 35 and a saturated oxygen intake flow meter 36 are respectively embedded on the surface of the first chamber 12, while the primary oxygen intake port 34 and the saturated oxygen intake port 37 are provided on the surface of the second chamber 13, and the air inlets are respectively connected to the primary flow meter 33 and the saturated oxygen intake flow meter 36 through pipes; the second chamber 13 is provided with an air inlet 11 on its side, and an oxygen generator 2 is provided inside, wherein the display screen 21 and the switch 22 of the oxygen generator 2 are respectively provided on the surface of the first chamber 12. The outer casing 1 is divided into two chambers. The first chamber 12 is equipped with the oxygen inhalation mechanism 3 and the control panel, making the operation more centralized and intuitive. The improved oxygen inhalation port is connected from the first chamber 12 to the surface of the second chamber 13 through an internal channel, eliminating the need for external pipeline layout. The display screen 21 and switch 22 of the oxygen generator 2 are located on the surface of the first chamber 12, forming a unified operating interface, which can improve the convenience of use and the overall neatness of the equipment.

[0034] The first compartment 12 and the second compartment 13 adopt an upper and lower structure, and a through hole is provided at the connection position. The design of the upper and lower structure of the first compartment 12 and the second compartment 13 results in a small footprint, a compact and reasonable layout of internal components, and a reduction in the need for external pipelines, thereby enhancing the overall aesthetics and portability of the equipment.

[0035] The second compartment 13 has symmetrically arranged carrying slots 14 on both sides and casters 15 at the bottom. The design of the carrying slots 14 and casters 15 greatly facilitates the movement and handling of the device. In use, users can easily lift the device for short-distance movement through the carrying slots 14, or use the casters 15 at the bottom to slide the device freely on a flat surface to achieve convenient long-distance movement, which is convenient for occasions that require frequent adjustment of the device position or transfer between different scenarios.

[0036] Example 4: Unlike Example 3, the primary flow meter 33 and the saturated oxygen flow meter 36 are symmetrically arranged on the left and right sides of the front of the first chamber 12, with a switch 22 in the middle and a display screen 21 above the switch 22. A primary flow control switch 32 is located below the primary flow meter 33, and a saturated oxygen flow control switch 35 is located below the saturated oxygen flow meter 36. All control components are concentrated on the same panel, forming a unified operating platform. This not only improves the overall aesthetics and saves space but also simplifies the operation process, reduces the possibility of misoperation, and allows users to quickly distinguish between the two different oxygen inhalation modes and operate directly in the corresponding areas, improving convenience and efficiency.

[0037] The first compartment 12 and the second compartment 13 adopt a left-right structure, and a through hole is provided at the connection position. The left-right structure design of the first compartment 12 and the second compartment 13 can adapt to the problem of insufficient installation height, and the through hole makes the internal layout of the equipment compact, reduces the need for external pipelines, and enhances aesthetics and portability.
