Description

Technical Field

[0001] This invention belongs to the field of medical oxygen supply technology, and in particular relates to an oxygen inhalation device and control method with monitoring and regulation functions. Background Technology

[0002] Oxygen therapy is a commonly used clinical treatment method to correct hypoxia, increase arterial blood oxygen partial pressure and oxygen saturation, and promote metabolism. It is an important adjunct treatment for many diseases. Commonly used auxiliary tools during oxygen therapy include oxygen tubing.

[0003] However, existing oxygen tubing only serves as an oxygen delivery channel and requires a separate pulse oximeter. This leads to the following drawbacks: 1. Patients must wear both the oxygen tubing and the pulse oximeter simultaneously, which is prone to falling off during activity, especially for elderly and bedridden patients with poor compliance; 2. Oxygen data must be manually read, requiring manual adjustment of the oxygen concentrator or wall-mounted oxygen supply terminal, making it impossible to respond promptly to fluctuations in oxygen levels; 3. It is incompatible with conventional oxygen concentrators on the market and hospital wall-mounted central oxygen supply systems, lacking versatility. Therefore, existing oxygen tubing has limited functionality, poor adaptability, and low adjustment efficiency. Summary of the Invention

[0024] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail, but this is not intended to limit the invention.

[0025] like Figure 1 and 2 As shown, in one embodiment of the present invention, the oxygen inhalation device with monitoring and adjustment functions includes a blood oxygen concentration monitoring component 100, a control component 200, an oxygen concentration delivery adjustment component 300, a delivery tube 400, and a nasal delivery component 700. The delivery tube 400 has a wearing cavity 401 for hanging on the user's ear. The input end of the nasal delivery component 700 is connected to the output end of the delivery tube 400, and the nasal delivery component 700 is connected to the user's nose. One side of the oxygen concentration delivery adjustment component 300 is connected to the input end of the delivery tube 400, and the one side of the oxygen concentration delivery adjustment component 300 is used to deliver oxygen. The blood oxygen concentration monitoring component 100 and the control component 200 are disposed on the delivery tube 400. The blood oxygen concentration monitoring component 100 is used to monitor the blood oxygen data of the user's ear. The blood oxygen concentration monitoring component 100 and the oxygen concentration delivery adjustment component 300 are electrically connected to the control component 200.

[0026] The technical solution of this invention employs a blood oxygen concentration monitoring component to monitor the blood oxygen saturation at the corresponding position of the ear in real time and feed it back to the control component. Combined with the oxygen concentration delivery adjustment component to control the oxygen delivery, precise regulation of oxygen concentration is achieved, while meeting the needs of special clinical scenarios. This improves the functional versatility of the oxygen inhalation device and enhances its adaptability. In addition, the delivery tubing and its inner cavity enable ear-hook wearing, ensuring the stability of ear position monitoring. Furthermore, blood oxygen monitoring, automatic flow adjustment, and other functions are integrated into one device, eliminating the need for an additional pulse oximeter, simplifying the wearing process, and improving patient compliance.

[0027] Specifically, in some implementations, such as Figure 1 and 2 As shown, the blood oxygen concentration monitoring component 100 includes an infrared sensor 110; the infrared sensor 110 is connected to the outer surface of the delivery conduit 400, and the infrared sensing end of the infrared sensor 110 is used to attach to the surface of the earlobe skin to monitor the blood oxygen status of the earlobe skin surface. This structure utilizes the advantages of thin earlobe skin and abundant blood vessels, resulting in minimal interference with the sensor monitoring signal. In some embodiments, such as... Figure 2 As shown, a connecting block 121 is provided on one side of the infrared sensor 110; a mounting ring block 120 is provided on the side of the connecting block 121 away from the infrared sensor 110; the mounting ring block 120 is sleeved on the outer surface of the conveying pipeline 400 to enable the infrared sensor 110 to slide flexibly to the preset position of the conveying pipeline 400 and to ensure the stability of its assembly. Further, the infrared sensor 110 includes a red light emitting unit, an infrared light emitting unit, a photoelectric receiving unit, and a signal processing chip, etc.; further still, the infrared sensor 110 uses a miniature reflective photoelectric sensor (such as MAX30102), with sensor size: 3.9mm × 2.8mm × 1.5mm, sampling frequency: 1 time / second, and monitoring error: ≤ ±2%. When in use, the red and infrared light from the infrared sensor 110 penetrates the skin of the earlobe and is absorbed by the hemoglobin in the subcutaneous blood vessels. The photoelectric receiving unit captures the reflected light signal, and the signal processing chip calculates the blood oxygen saturation (SpO2) based on the difference in light absorption between oxygenated hemoglobin and deoxygenated hemoglobin. The data sampling frequency is 1 time / second, and the monitoring error is ≤±2%.

[0028] Specifically, in some implementations, such as Figure 1 and 2As shown, the oxygen concentration delivery and regulation component 300 includes a quantitative controller 310 and a regulating valve 320. The quantitative controller 310 is connected and disposed inside the delivery pipeline 400. The output end of the regulating valve 320 is connected and disposed to the input end of the delivery pipeline 400. The input end of the regulating valve 320 is used for connection to the oxygen source equipment. The quantitative controller 310 and the regulating valve 320 are electrically connected to the control component 200. This structure controls the oxygen flow through the quantitative controller 310 and the regulating valve 320 to reduce the workload of nurses' rounds and manual flow adjustment; thereby achieving the requirement of precise oxygen flow control and providing high flexibility in use. Among them, the quantitative controller 310 is a specialized device for precise quantitative adjustment and monitoring of parameters such as oxygen flow rate, oxygen inhalation duration, and oxygen supply mode. Its core function is to replace the manual, coarse adjustment of traditional simple oxygen flow meters. Through digital / mechanical precision control, it makes the oxygen therapy parameters (flow rate, FiO2) of the dual nasal cannulas more stable and traceable, adapting to the needs of standardized clinical oxygen therapy and precise home oxygen therapy. It is divided into two main categories: basic mechanical quantitative type and intelligent digital quantitative type, both compatible with central oxygen supply, oxygen cylinders / oxygen concentrators; the PM-7000 is preferred. The regulating valve 320 uses a miniature electromagnetic proportional regulating valve with an adjustment accuracy of ±1% and a working pressure range of 0.02-0.1 MPa. Furthermore, such as... Figure 2 As shown, the first side end of the regulating valve 320 is provided with an output pipe 321; the output pipe 321 is connected to the input end of the delivery pipe 400; the second side end of the regulating valve 320 is provided with a limiting ring 322, and the outer surface of one side end of the delivery pipe 400 is engaged with the inside of the limiting ring 322 to realize the single-branch flow action and form a ring-shaped ear structure, thereby improving the stability of wearing.

[0029] Specifically, in some implementations, such as Figure 1 and 2 As shown, the delivery pipeline 400 includes a main delivery section 402 and an output section 403 connected in sequence. The side of the main delivery section 402 away from the output section 403 is connected to the regulating valve 320 (the middle output pipe 321). The side of the output section 403 away from the main delivery section 402 is connected to the nasal inhalation delivery component 700. The outer surface of the output section 403 (the middle fixed protrusion 404) is connected to the regulating valve 320 (the middle limiting ring 322). The wearing cavity 401 is formed between the main delivery section 402, the output section 403, and the regulating valve 320. That is, the delivery pipeline 400 has an arc-shaped structure. In other words, the wearing cavity 401 is an area that fits the earlobe skin to avoid compressing blood vessels and ensures comfortable wear for a long time.

[0030] Specifically, in some embodiments, the control component 200 includes a mounting housing 210, a control button 220, a signal communication module 230, a warning light, a control chip, and a storage unit; the mounting housing 210 is sleeved on the outer surface of the delivery pipeline 400 (the main delivery section 402); the control chip and storage unit are disposed inside the mounting housing 210, and the control button 220, the signal communication module 230, and the warning light are respectively connected to the outer surface of the mounting housing 210; and the blood oxygen concentration monitoring component 100 (the mid-infrared sensor 110) and the oxygen concentration delivery regulating component 300 (the mid-quantitative controller 310 and the regulating valve 320) are respectively electrically connected to the signal communication module 230; the control button 220, the signal communication module 230, the warning light, and the storage unit are respectively electrically connected to the control chip; the signal communication module 230 is electrically connected to the microcontroller (MCU); the microcontroller (MCU) is an STM32L476 ultra-low power single-chip microcomputer; the control chip is an STM32L476. The signal communication module 230 includes at least two (low power) Bluetooth (5.0) modules; the mounting housing 210 also has a miniature rechargeable lithium battery (capacity: ≤100mAh; battery life: ≥72 hours; charging interface: USB-C) inside to provide power.

[0031] Specifically, in some implementations, such as Figure 1 and 3 As shown, the nasal suction delivery component 700 includes a connecting tube 710, a neck hook connector, and at least one nasal cannula 720; one end of the connecting tube 710 is connected to the delivery pipeline 400 (middle output section 403); one end of the nasal cannula 720 is connected to the interior of the connecting tube 710; the mounting end of the neck hook connector is connected to the outer surface of the connecting tube 710, and a suspension cavity is provided between the neck hook connector and the connecting tube 710; this achieves partial wearing stability of the nasal suction tube and can reduce the pulling stress on the ear, thereby improving wearing comfort.

[0032] Specifically, in some implementations, such as Figure 3 As shown, the neck strap connector includes a positioning locking component 731, a neck strap adjusting component 732, and a splicing mounting component 733; the positioning locking component 731 is circumferentially connected to the splicing mounting component 733 and the connecting guide tube 710; the splicing mounting component 733 is connected to the outer surface of the neck strap; the two ends of the neck strap adjusting component 732 are respectively connected to the two ends of the splicing mounting component 733; so as to achieve wearing stability and adapt to the heads of different users.

[0033] In some implementation methods, such as Figure 3As shown, the neck adjustment component 732 includes a fixing strap 7321, an adjustment strap 7322, and a connecting buckle 7323. One end of the fixing strap 7321 is disposed on one end of the splicing mounting component 733; the other end of the fixing strap 7321 is fixedly connected to one end of the connecting buckle 7323; one end of the adjustment strap 7322 is disposed on the other end of the splicing mounting component 733; the other end of the adjustment strap 7322 is detachably connected to the connecting buckle 7323 to increase or decrease the volume of the suspension cavity. Furthermore, the connecting buckle 7323 is selected as a H-shaped connecting buckle; the other end of the adjustment strap 7322 is wrapped around and snapped into the interior of the H-shaped connecting buckle to improve the convenience and speed of adjustment.

[0034] Specifically, in some implementations, such as Figure 3 and 5 As shown, the positioning and locking component 731 includes a first hook and loop layer 7312, a base layer 7311, and a second hook and loop layer 7313 that are sequentially stacked and connected as a single unit; the neck adjustment component 732 (central fixing strap 7321) is connected to the base layer 7311 (by sewing or adhesive, etc.); when the positioning and locking component 731 is in the wrapped assembly state, the first hook and loop layer 7312 is connected to the second hook and loop layer 7313 to further improve the assembly stability between the splicing installation component 733 and the connecting guide tube 710, and to improve the ease of disassembly.

[0035] Specifically, in some implementations, such as Figure 3 and 4 As shown, the splicing mounting component 733 has at least one positioning hole 7331, and the outer surface of the nasal cannula 720 is engaged with the interior of the positioning hole 7331. This structure achieves multiple locking operations through positioning and locking between the nasal cannula 720 and the positioning hole 7331, the winding locking of the positioning locking component 731, and the circumferential locking of the neck adjustment component 732, thereby improving wearing stability and reducing pulling stress on the ears. For example, Figure 2 As shown, there are two positioning holes 7331 and two nasal cannulas 720 to enable oxygen inhalation through both nostrils.

[0036] In some implementation methods, such as Figure 4As shown, the side end of the splicing mounting component 733 is provided with a limiting groove 7332; one side end of the neck adjustment component 732 (the middle fixing strap 7321 and / or the adjustment strap 7322) is provided with a connecting block 7324; the connecting block 7324 is connected to the inside of the limiting groove 7332. Further, the inside of the limiting groove 7332 is provided with at least one limiting protrusion 7333; one side surface of the connecting block 7324 is provided with at least one locking groove 7325; the limiting protrusion 7333 is engaged with the inside of the locking groove 7325. This structure, by having the left and right side walls of the connecting block 7324 abut against the inside of the limiting groove 7332, combined with the upper limiting protrusion 7333 being engaged with the locking groove 7325, improves the assembly stability of the structure and enhances the ease of disassembly.

[0037] Specifically, in some implementations, such as Figure 1 As shown, the oxygen inhalation device with monitoring and adjustment functions also includes a backup flow guide component 600; the backup flow guide component 600 is connected to the delivery line 400 (middle output section 403), and the backup flow guide component 600 is detachably connected to the delivery line 400 (middle output section 403) to realize a backup function for nasal inhalation operation. In some embodiments, such as... Figure 1 and 6 As shown, the spare flow guiding component 600 includes a connecting section 610, an abutment portion 620, and a surrounding portion 630; the connecting section 610 is connected to the delivery pipeline 400 (mid-output section 403); the abutment portion 620 is connected to the outer surface of the connecting section 610; the inner wall of the abutment portion 620 abuts against the outer surface of the delivery pipeline 400 (mid-output section 403); one end of the surrounding portion 630 is connected to the bottom of the abutment portion 620; the surrounding portion 630 surrounds and is connected to the outer surface of the delivery pipeline 400 (mid-output section 403); and the other end of the surrounding portion 630 is engaged with the abutment portion 620 by a fixing post 640. Nearly half of the connecting section 610's output end is fitted with a sealing plug to achieve a sealing effect when not in use.

[0038] The present invention also proposes an oxygen inhalation control method, which operates based on an oxygen inhalation device with monitoring and adjustment functions. The specific structure of the oxygen inhalation device with monitoring and adjustment functions is as described in the above embodiments. Since the present oxygen inhalation control method adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0039] The oxygen control method includes the following steps: S1. The user wears the oxygen inhalation device under the condition of preset basic oxygen flow rate; wherein, the preset basic oxygen flow rate can be 3L / min, etc.; further, the oxygen inhalation device is inserted into the hospital wall-mounted oxygen supply terminal or home oxygen generator, and the nurse presets the basic oxygen flow rate (such as 3L / min) through the terminal knob; the user wears the oxygen inhalation device, the nasal cannula 720 is inserted into the nasal cavity, and the infrared sensor 110 on the inner side of the ear hook is in close contact with the skin of the earlobe. S2. Use the blood oxygen concentration monitoring component 110 to acquire real-time earlobe blood oxygen data and transmit it to the control component 200; S3. Determine the adjustment operation and alarm logic operation based on the earlobe blood oxygen data; S4. Based on the adjustment and alarm logic operations, generate summary data and transmit it to the data storage center. Throughout the process, the Bluetooth module synchronizes blood oxygen data, oxygen flow data, mode status, and alarm records to associated devices (such as the nurse station host and the hospital information system HIS) in real time according to the adjustment and alarm logic operations, facilitating data traceability and review.

[0040] Specifically, in some embodiments, the step of determining and acquiring the adjustment operation and the alarm logic operation in S3 includes: When the blood oxygen concentration of the earlobe blood oxygen data is 90%-95%, continuous monitoring feedback is generated, and active coordinated oxygen supply operation is generated between the infrared sensor 110, the control component 200 and the oxygen concentration delivery adjustment component. When the blood oxygen concentration of the earlobe is between 85% and 90%, a level one warning feedback is generated. Active coordinated oxygen supply is then performed within a first preset time. If the blood oxygen concentration of the earlobe does not recover to 90%-95%, the warning feedback is upgraded to a potentially dangerous level. In other words, when the blood oxygen concentration of the earlobe is between 85% and 90%, the oxygen inhalation device is still in automatic mode. The device needs to increase the oxygen flow rate by 1-2 L / min based on the preset baseline oxygen flow rate without triggering an alarm, continuously monitoring blood oxygen changes. If the blood oxygen level rises to ≥95% after adjustment, the new flow rate is maintained. If there is no improvement within 5 minutes, the warning feedback is upgraded to a potentially dangerous level. When the blood oxygen concentration of the earlobe is less than 85% for a second preset time, a secondary warning feedback is generated; and active coordinated oxygen supply operation is performed within a third preset time. If the blood oxygen concentration of the earlobe does not recover to 90%-95%, the warning feedback is upgraded to require intervention. That is to say, when the blood oxygen concentration is less than 85% for 30 seconds, the oxygen inhalation device is still in automatic mode, but the oxygen inhalation device first performs maximum automatic adjustment (a single increase does not exceed 2L / min, and does not exceed the clinical safety limit of 6L / min), and simultaneously triggers a signal alarm (the red indicator light on the ear hook module flashes + Bluetooth push alarm information to the nurse station host / responsible nurse's mobile phone, displaying "Patient's blood oxygen is too low, automatic flow adjustment has been performed, please confirm"); if the blood oxygen still does not recover after adjustment, or if the nurse needs to intervene after receiving the alarm, it can be directly switched to manual mode, and the flow can be precisely adjusted through the knob on the wall terminal. At this time, the active coordinated oxygen supply operation function is suspended, and the alarm continues until the blood oxygen recovers to a safe range; When the blood oxygen concentration of the earlobe is less than 85% and exceeds a second preset time, and the infrared sensor 110 and / or control component 200 and / or oxygen concentration delivery adjustment component malfunction, an emergency fault alarm is directly triggered. Simultaneously, the system automatically switches to manual mode, locking the adjustment valve to prevent incorrect adjustment. The alarm message reads "Equipment malfunction, please adjust manually and repair," ensuring patient oxygen therapy safety. Furthermore, upon receiving the alarm, the nurse can switch to manual mode based on clinical judgment and precisely adjust the oxygen flow rate using the wall-mounted terminal knob. Once blood oxygen levels return to normal, the system can switch back to automatic mode, restoring the device's autonomous adjustment function.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
