Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and more specifically, relates to a portable xenon inhaler. Background Technology

[0002] Currently, xenon, as an inert gas, has important applications in the medical field. For example, it offers advantages in anesthesia such as rapid onset, quick recovery, and minimal impact on the respiratory and circulatory systems. It also shows promising potential in neuroprotection and the treatment of post-traumatic stress disorder. However, existing xenon inhalation devices have many shortcomings and cannot meet the needs of mobile clinical treatment.

[0003] Currently, Chinese patent CN108543187A discloses a push-type xenon-oxygen mixed gas inhalation system device, including a base, an oxygen main pipe and a xenon main pipe. A working box 1 is rotatably mounted on top of the base, and an oxygen cylinder and a xenon cylinder are mounted in the working box 1. A working box 2 is mounted above the working box 1, and a circuit box and a working box are fixed in the working box 2 respectively. The circuit box is equipped with a control system. The working box has a xenon inlet hole, an oxygen inlet hole and an output hole. The input end of the oxygen main pipe is connected to the oxygen cylinder, and the output end of the oxygen main pipe passes through the oxygen inlet hole and is connected to the output hole. The input end of the xenon main pipe is connected to the xenon cylinder, and the output end of the xenon main pipe passes through the xenon inlet hole and is connected to the output hole. The working box is equipped with an adjustment mechanism that can adjust the output ratio of oxygen and xenon.

[0004] While this type of device can perform xenon-oxygen mixing, it has several drawbacks: its overall structure is large, it relies on a fixed gas supply and a complex control system, and it can only be used in fixed locations such as operating rooms and intensive care units. It requires a large number of sensors, controllers, and solenoid valves, resulting in high power consumption. For mobile treatment scenarios such as patients requiring transport, field emergency care, or primary healthcare institutions, the push-type device cannot be flexibly adapted, which severely limits the application scope of xenon therapy.

[0005] Meanwhile, the device lacks an independent gas mixing chamber, resulting in an unstable oxygen-xenon mixing ratio that affects treatment effectiveness; the gas pressure control lacks an effective adjustment mechanism, and excessively high pressure in the oxygen chamber may cause equipment malfunctions or safety hazards; the connection between the mask and the device is complex and inconvenient to replace, which may delay treatment in emergency situations.

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Please see Figures 1 to 7 The present invention provides a technical solution: a portable xenon inhaler, comprising a work box 7, wherein the work box 7 is independently provided with an oxygen storage chamber 3 and a xenon-oxygen storage chamber 4, the xenon-oxygen storage chamber 4 being connected to a breathing bag 41; the oxygen storage chamber 3 is connected to the xenon-oxygen storage chamber 4 through a one-way inhalation port 42 for unidirectional oxygen supply to the xenon-oxygen storage chamber 4; the oxygen storage chamber 3 is provided with an overflow device 31, and the xenon-oxygen storage chamber 4 is provided with a one-way inhalation port 42 and a one-way exhalation port 43, which are connected to a breathing tube 5;

[0032] The oxygen storage chamber 3 is connected to an oxygen source via a pipeline, and the pipeline of the oxygen source is equipped with a flow meter 34; the xenon-oxygen storage chamber 4 is connected to a xenon source via a pipeline, and the pipeline of the xenon source is equipped with a metering valve 44 to control the emission amount.

[0033] Furthermore, such as Figure 1 , 3 As shown in Figure 4, the oxygen storage chamber 3 is also connected to the breathing bag 41. The breathing bag 41 is located above the oxygen storage chamber 3 and the xenon oxygen storage chamber 4. The top of the work box 7 is equipped with an adjustment frame 803, and the bottom of the adjustment frame 803 is also equipped with symmetrical elastic ropes 10. The elastic ropes 10 are connected to the top of the breathing bag 41 to hoist and position the breathing bag 41 and prevent the breathing bag 41 from swaying left and right.

[0034] The downward-opening breathing bag 41 does not generate inspiratory resistance when the patient inhales; when the patient exhales, the expiratory phase is positive pressure, which can easily overcome the slight resistance brought by the soft elastic bag or corrugated tube, and achieve the effect of blowing a balloon with excellent compliance. This resistance is conducive to the expansion of small alveoli and facilitates the user's breathing.

[0035] Furthermore, a work frame 8 is provided on one side of the work box 7. Symmetrical positioning blocks 801 are provided on the work frame 8 and the work box 7. Symmetrical guide posts 802 are provided on the positioning blocks 801. The guide posts 802 are fitted with the sliding groove in the adjusting frame 803 with clearance. When there is no load, the sleeve can remain stationary on the guide rod. After applying axial hand force, it can slide smoothly and slowly, and the height can be freely adjusted to improve the overall convenience. A handle 804 is provided in the center of the adjusting frame 803 for easy carrying and transportation. A display is also provided on one side of the adjusting frame 803. The display is electrically connected to the monitoring component and transmits all monitoring data to the display for statistical analysis.

[0036] Furthermore, the oxygen source uses a quick-connect oxygen tank 1, and the xenon source uses a quick-connect xenon tank 2. A quick-connect base 11 is installed on the work frame 8. The quick-connect base 11 is used to install the quick-connect oxygen tank 1 and the quick-connect xenon tank 2 respectively, and is pressed and fixed by the positioning spring 111 installed on the quick-connect base 11. The quick-connect base 11 of the quick-connect oxygen tank 1 is connected to the oxygen storage chamber 3 through a pipe. A flow meter 34 is installed on the pipe of the quick-connect oxygen tank 1 to control the oxygen flow rate. The quick-connect base 11 of the quick-connect xenon tank 2 is connected to the xenon oxygen storage chamber 4 through a pipe, and the single release of xenon gas is controlled to be 50ml by the metering gas supply valve 44.

[0037] Furthermore, the breathing circuit 5 includes an inspiratory circuit, an expiratory circuit, and an adapter. The adapter connects the inspiratory circuit and the expiratory circuit. The inspiratory circuit is connected to a one-way inspiratory circuit, and the expiratory circuit is connected to a one-way expiratory circuit. A carbon dioxide absorption canister 6 is provided between the one-way expiratory port 43 and the breathing circuit 5 to absorb exhaled carbon dioxide. The adapter is connected to a mask 52.

[0038] Through the above structure, the xenon-oxygen reservoir 4 is sealed and connected to the user's mouth and nose via the breathing tubing 5 and the end mask 52, providing the user with a closed xenon-oxygen inhalation loop. The flow meter 34 controls the quick-connect oxygen canister 1 to supply oxygen to the oxygen reservoir 3 at a suitable flow rate, optimally 1-2 L / min. Oxygen in the oxygen reservoir 3 is released unidirectionally into the xenon-oxygen reservoir 4, continuously supplying the xenon-oxygen reservoir 4 with a suitable amount of oxygen. The quick-connect xenon canister 2 supplies xenon gas of a suitable volume to the xenon-oxygen reservoir 4 through the metering valve 44. The combination of the two ensures that the xenon-oxygen concentration ratio is controlled at an optimal 1:1, which can meet the oxygen inhalation needs and achieve a better analgesic effect for cancer pain patients.

[0039] like Figure 7As shown, the overflow device 31 is cylindrical in shape, with water-blocking and air-permeable membranes 313 at the top and bottom. A sealing liquid is injected between the water-blocking and air-permeable membranes 313, with the upper surface of the sealing liquid lower than the upper water-blocking and air-permeable membrane 313. A scale value 311 is provided on the side of the overflow device 31 for observing changes in the test liquid. The pore size of the water-blocking and air-permeable membrane 313 is 0.1-5μm, allowing liquid water to pass through, but blocking gas molecules due to their long path of freedom; its permeability is >500g / m³. 2 / 24h, gas permeability <10cc / m 2 / day.

[0040] During use, the flow meter 34 is adjusted to control the flow rate of the quick-connect oxygen tank 1 to be slightly higher than the human body's breathing requirements. When the xenon oxygen gas pressure in the xenon oxygen storage chamber 4 rises higher than the oxygen pressure in the oxygen storage chamber 3, the oxygen cannot enter the oxygen storage chamber 3 in reverse due to the action of the one-way inhalation port 42 connecting the oxygen storage chamber 3 and the xenon oxygen storage chamber 4. The oxygen in the oxygen storage chamber 3 stops entering the xenon oxygen storage chamber 4, and the excess oxygen in the oxygen storage chamber 3 enters the pressure relief device 31. The detection liquid in the pressure relief device 31 changes with the scale value 311, which can be observed in real time.

[0041] The inner wall of the xenon-oxygen storage chamber 4 is also equipped with a fan 45 for mixing gases. Xenon gas has a large molecular weight and is denser than oxygen. The fan 45 operates inside the xenon-oxygen storage chamber 4 to ensure that xenon and oxygen are fully mixed, thus preventing xenon from depositing in the lower area of ​​the xenon-oxygen storage chamber 4 when the airflow speed is slow, which would be detrimental to treatment.

[0042] like Figure 6 As shown, both the one-way inhalation port 42 and the one-way exhalation port 43 are tubular, with an isolation plate 421 inside the tube. The isolation plate 421 has air holes, and a sealing sheet 422 that can limit floating is covered above the air holes. The diameter of the sealing sheet 422 is larger than the diameter of the air holes to achieve full coverage. A mesh cover fixed to the isolation plate 421 is provided outside the sealing sheet 422, and the limiting floating is achieved through the mesh cover.

[0043] When the user inhales, the breathing bag 41 decreases in volume, and the xenon-oxygen mixture is supplied to the user via the one-way inhalation port 42 on the inhalation line and the mask 52 on the adapter. When exhaling, the user's exhaled gas flows through the mask 52 on the adapter into the exhalation line. The carbon dioxide in the exhaled gas is absorbed by the carbon dioxide absorption particles filled in the carbon dioxide absorption canister 6 when it passes through the carbon dioxide absorption canister 6, and is converted into a xenon-oxygen mixture that enters the xenon-oxygen reserve chamber 4 through the one-way exhalation port 43. The volume of the breathing bag 41 provides space for the patient's breathing. Before use, the gas in the bag should be kept sufficient to meet the patient's breathing needs, that is, the total volume of the breathing bag 41 should be greater than the user's tidal volume, with an optimal setting of 1.5-3L.

[0044] The one-way inhalation port 42 on the inhalation line, the one-way exhalation port 43 on the exhalation line, and the adapter are all connected to the self-sealing quick-connect fitting 51 via pipes. The self-sealing quick-connect fitting 51 on the inhalation and exhalation lines is installed on the side wall of the xenon oxygen reservoir 4. The self-sealing quick-connect fitting 51 of the adapter engages with the socket at one end of the mask 52. When a single treatment is completed, the patient exhales the air in their lungs as much as possible and pulls out the mask 52 to achieve self-sealing, thus forming a seal between the xenon oxygen reservoir 4, the breathing bag 41, and the breathing line 5, reducing xenon waste. The pipe on the one-way inhalation port 42 of the inhalation line is also equipped with an oxygen concentration sensor 46 to monitor the oxygen concentration in the xenon oxygen reservoir 4.

[0045] Furthermore, the work rack 8 is also equipped with a power supply for electrically connecting all plug-in components, providing the necessary power to all plug-in components.

[0046] The specific usage and function of this embodiment are as follows: Before use, supply oxygen to the xenon oxygen reserve chamber 4 at a slightly higher flow rate, 2L / min is optimal, so that the breathing bag 41 is kept in a nearly inflated state. During actual use, observe the state of the blind end breathing bag 41 and gradually reduce the oxygen flow rate. As long as the breathing bag 41 is still kept in a nearly inflated state during the user's exhalation phase, oxygen waste can be reduced. During treatment, the inhaled gas is a mixture of xenon and oxygen. By monitoring the oxygen concentration, the xenon concentration can be known, thereby maintaining an appropriate ratio of the two concentrations to ensure the treatment effect and avoid hypoxia events.

[0047] It is important to note that before the first treatment, oxygen should be fully released to expel air from the cavity and fill it with pure oxygen. During the initial stage of treatment, a suitable amount of xenon gas should be slowly injected into the xenon-oxygen reservoir 4 to adjust the xenon-oxygen gas ratio to 50%. This concentration is safe and effective. Once the oxygen concentration drops to 50%, no further xenon gas needs to be added during this treatment; only a continuous supply of a suitable amount of oxygen is required. For subsequent uses, first continuously and appropriately add oxygen to the xenon-oxygen reservoir 4. During the initial stage of treatment, the oxygen concentration should be slightly higher than 50%. Then, a suitable amount of xenon gas should be added to reduce the oxygen concentration to 50%. After this, no further xenon gas needs to be added during this treatment.

[0048] When the user inhales, the breathing bag 41 shrinks in volume, and the xenon-oxygen mixture is supplied to the user through the one-way inhalation port 42 on the inhalation tubing and the mask 52 on the adapter. When exhaling, the user's exhaled gas flows through the mask 52 on the adapter into the exhalation tubing. The carbon dioxide gas in the exhaled gas is absorbed by the carbon dioxide absorption particles filled in the carbon dioxide absorption canister 6 when it passes through the carbon dioxide absorption canister 6, and is converted into xenon-oxygen mixture. It then enters the xenon-oxygen reservoir 4 through the one-way exhalation port 43 for recycling. When the treatment is finished, the patient exhales the air from the lungs as much as possible and removes the mask 52, which self-seales, forming a seal between the xenon-oxygen reservoir 4, the breathing bag 41, and the breathing tubing 5, reducing xenon gas waste.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
