[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] Please refer to Figures 1 to 3, the first embodiment of the present application provides a medicine chamber structure 10 for a pulse respiratory therapeutic device, the medicine chamber structure 10 includes a connecting tube body 11, a medicine chamber 12 and a sensor component 13; the connecting tube body 11 has an external end 111 and a functional end 112 arranged relatively, and an inner cylinder 113 located between the external end 111 and the functional end 112, which can be conveniently connected to the air flow path of the pulse respiratory therapeutic device; the medicine chamber 12 is arranged on the functional end 112 and is connected to the inner cylinder 113 of the connecting tube body 11, so that the drug diffusion, mixing and temperature regulation have higher flexibility and timeliness, and because the medicine chamber 12 is directly connected to the inner cylinder 113, the medicine The drug can be efficiently circulated inside the tube body accompanied by pulsed airflow, reducing drug retention and waste; the sensor component 13 is arranged on the functional end 112 and is connected to the inner cylinder 113 of the connecting tube body 11, thereby facilitating real-time monitoring during drug delivery, such as detecting indicators such as drug concentration, flow rate or temperature; when the sensor component 13 detects deviation from the preset value, the instrument can be linked to perform automatic or manual adjustment; wherein, the drug chamber 12 has a drug chamber axis 14, and the connecting tube body 11 has a tube body axis 15, and the drug chamber axis 14 is set at an angle α to the tube body axis 15, which can prevent the drug from splashing out disorderly in the axial direction and reduce drug deposition and dead angles.

[0036] In some embodiments, the drug chamber axis 14 and the tube body axis 15 are arranged at an angle α of 75°-85°. This effectively alleviates the accumulation or splashing of the drug solution caused by a single axial flow, allowing the drug solution to be more smoothly transported and atomized along the pulsed airflow. Furthermore, this inclination angle provides a more stable fluid environment for the sensor assembly 13 to measure drug flow and concentration changes, thereby further improving the detection accuracy and response speed of indicators such as drug concentration or temperature, while achieving a compact structure and user-friendly operation.

[0037] In some embodiments, the drug chamber 12 further includes: a drug chamber body 120, an opening adjustment member 124 and a valve head 125, wherein the drug chamber body 120 is sequentially provided with a main section 121 and a diameter reduction section 122 along the axial direction, wherein the diameter reduction section 122 is connected to the functional end 112, and the diameter reduction section 122 is provided with a drug delivery hole 123; the diameter reduction section 122 is directly connected to the functional end 112, and the diameter reduction section 122 is provided with a drug delivery hole 123, so that the drug solution is buffered by the flow velocity gradient during the transition from a wide to a narrow pipe, thereby reducing the flow velocity gradient caused by sudden changes. The eddy current or turbulence caused by the cross-section can be reduced, and the convergence and orientation of the drug flow path can be achieved within a shorter distance, which is convenient for subsequent humidification or airflow mixing, and is more suitable for small-dose drug delivery under pulsed airflow, reducing drug waste and blockage risks; the opening adjustment member 124 is connected to the main body section 121; the valve head 125 is arranged at the end of the opening adjustment member 124 close to the drug delivery hole 123, and the gap between the valve head 125 and the drug delivery hole 123 is adjusted by adjusting the opening adjustment member 124 to control the drug delivery amount. The opening adjustment member 124 is installed on the main body section 121 and forms a matching relationship with the valve head 125. The valve head 125 is located near the drug delivery hole 123 and is used to change the gap between the valve head 125 and the hole wall; when the amount of medication needs to be increased, the opening adjustment member 124 is rotated or moved to increase the gap between the valve head 125 and the drug delivery hole 123, thereby increasing the amount of drug liquid flowing through per unit time; on the contrary, reducing the gap can reduce the dripping rate or flow rate of the drug liquid, or even shut off the drug delivery passage; thereby taking into account both the adjustable range and the convenience of operation, allowing clinical personnel or system control units to flexibly set different doses to better meet the patient's personalized treatment needs.

[0038] In some embodiments, the axial cross-sectional shape of the inner wall of the reduced diameter section 122 is set to a most rapid descent curve, thereby forming a smoother, faster and more controllable transmission path when the liquid medicine flows, reducing turbulence or liquid medicine retention caused by sudden shrinkage; on the other hand, the coordination between the dosing hole 123 and the valve head 125 is also more precise, so that the dosage change can be adjusted by rotating the regulating valve core at a small angle.

[0039] In some embodiments, the valve head 125 is configured as a flexible valve head 125, and the axial cross-section of the valve head 125 is configured as a most rapid drop curve. By using a valve head 125 made of a flexible material, a more snug sealing contact can be formed under the combined action of the compressed air flow and the trace amount of liquid medicine, which helps to maintain a precise micro-gap between the reduced diameter section 122 and the drug delivery hole 123, and is less likely to cause problems such as jamming or excessive gaps that may occur with a hard valve head 125; on the other hand, the axial cross-section in the most rapid drop curve shape can help the liquid medicine to quickly and smoothly pass through the section near the valve head 125 at the most optimized downstream speed when the flexible valve head 125 is impacted by the fluid, thereby avoiding accumulation or backflow of the liquid medicine due to flow field turbulence and making the operation of adjusting the valve core more sensitive to the control of the drug delivery amount.

[0040] In some embodiments, the drug delivery hole 123 includes a transition hole section, a first speed drop section, a straight hole section, and a second speed drop section in sequence along the axial direction, so that after entering the drug delivery hole 123, the drug solution is first smoothly guided in the transition hole section, and then gradually transitions to the first speed drop section for rapid and stable flow; and when the drug solution passes through the straight hole section, it is accelerated and output in the second speed drop section in a mirror-symmetrical manner with the first speed drop section, which is conducive to reducing turbulence or accumulation caused by sudden changes in cross-section. The transition hole section is used to connect the reduced diameter section 122 and the first speed drop section. The first speed drop section and the second speed drop section are symmetrically arranged relative to the straight hole section. The hole walls of the axial cross-sections of the first speed drop section and the second speed drop section are both arranged in the shape of the most rapid drop curve; under the negative pressure of the compressed air flow, the drug solution or atomized droplets pass through the hole wall in approximately the shortest time, avoiding the occurrence of large-scale vortex areas or dead angles during acceleration or deceleration. At the same time, this symmetrical layout can also maintain the consistency of flow characteristics during the fine-tuning process of the valve head 125 or the adjustment member, thereby improving the controllability and stability of drug delivery.

[0041] In some embodiments, the opening adjustment member 124 is configured as a butterfly screw. The main body section 121 is provided with a threaded hole 1211. One end of the butterfly screw is connected to the threaded hole 1211 and extends from the main body section 121. The other end of the butterfly screw is connected to the valve head 125. By rotating the butterfly screw on the main body section 121, the screw is controlled to move axially along the threaded hole 1211, thereby causing a corresponding change in the gap between the valve head 125 and the drug delivery hole 123. The butterfly design at the end of the butterfly screw makes manual adjustment more convenient and intuitive, and also facilitates quick fine-tuning on the operation panel or at the patient's bedside. Therefore, the drug delivery amount can be flexibly changed according to drug delivery needs without the need for specialized tools, balancing user-friendliness and adjustment accuracy.

[0042] In some embodiments, the opening adjustment member 124 includes a servo motor and an adjustment screw: the servo motor is arranged at one end of the main body section 121 away from the reduced diameter section 122, one end of the adjustment screw is connected to the output shaft of the servo motor, and the other end is connected to the valve head 125. It can be seen that the servo motor can accurately drive the adjustment screw to move axially after obtaining instructions (such as from a control panel or automatic detection data), thereby adjusting the gap between the valve head 125 and the drug delivery hole 123, and realizing automatic control of the drug delivery volume; compared with traditional manual rotation or fixed adjustment methods, the servo motor drive can not only provide more delicate step accuracy, but also can be combined with the real-time detection results of the sensor component 13 for dynamic correction, greatly improving the accuracy and intelligence level of the pulse respiratory therapy device in drug delivery.

[0043] In some embodiments, the sensor component 13 is detachably connected to the functional end 112 and includes a pressure sensor, a temperature sensor, and a humidity sensor. By designing the sensor component 13 to be detachable, it is ensured that it can be easily removed and replaced or calibrated during daily maintenance or troubleshooting, and it also allows users to quickly switch between sensor elements of different levels, precisions, or types according to actual needs or treatment processes. Furthermore, by simultaneously configuring pressure, temperature, and humidity sensors in the sensor component 13, multi-dimensional detection of the airflow entering the medicine chamber 12 and the drug-liquid mixing environment can be performed. When a certain sensor indicator deviates from the preset range, the device can promptly issue an alarm or jointly adjust the opening adjustment member 124 and the valve head 125 to achieve dynamic control of the drug delivery process, thereby effectively improving the safety and applicability of the pulse respiratory therapy device. It should be noted that the sensor component 13 can realize real-time monitoring of compressed air and drugs by the sensor component 13 by making a hole in the functional end 112.

[0044] In some specific embodiments, before pulse therapy is performed, the drug is first injected into the drug reservoir 12 of the drug reservoir structure 10. The connecting tube body 11 of the drug reservoir structure 10 is then connected to the pulse therapy device. The opening adjustment member 124 is then adjusted as needed to adjust the gap between the valve head 125 and the drug delivery hole 123, thereby controlling the drug delivery amount. The sensor assembly 13 monitors the flow rate, temperature, and drug delivery amount of the compressed air flow, and adjusts the gap between the valve head 125 and the drug delivery hole 123 in real time. By arranging the drug reservoir 12 and the sensor assembly 13 at the functional end 112 of the connecting tube body 11, and arranging the drug reservoir axis 14 at an angle to the tube body axis 15, the drug reservoir structure 10 no longer needs to be installed axially of the pulse therapy device's pipeline, allowing the drug to be delivered and atomized closer to the humidification and airflow generation points. At the same time, the synchronous setting of the sensor component 13 provides conditions for real-time detection and adjustment of the drug delivery process, overcoming the shortcomings of the traditional terminal drug chamber that cannot humidify, adjust the drug concentration or perform dynamic monitoring.

[0045] Please refer to further Figure 4 The second embodiment of the present application provides a pulse therapy device, which includes a therapy device body 20, a humidification tank 30, a handle 40 and a medicine chamber structure 10 as provided in the first embodiment of the present application, so as to achieve efficient humidification and heating of the compressed air flow, and improve the treatment comfort and practicality of the equipment.

[0046] The therapeutic device body 20 is provided with a tank mounting portion 21 and a compressed air duct 22; by designing the tank mounting portion 21 on the therapeutic device body 20, the humidification tank 30 can be integrated and installed on the therapeutic device body 20, making the installation of the humidification tank 30 more stable and providing a reliable air duct connection path for the airflow from the compressed air source to the humidification tank 30, thereby ensuring the overall air tightness and operational stability of the equipment.

[0047] The humidifier tank 30 is detachably mounted on the tank mounting portion 21 and is provided with an air inlet pipe 31 and an air outlet pipe 32. The inlet of the air inlet pipe 31 is connected to the compressed air passage 22. This facilitates cleaning and maintenance of the humidifier tank 30 and facilitates replacement or upgrading of the humidifier device according to different treatment needs, effectively avoiding the complex structure and high maintenance costs of traditional external humidification devices. Furthermore, the air inlet pipe 31 of the humidifier tank 30 is connected to the compressed air passage 22, allowing the compressed air to smoothly enter the humidifier tank 30 for humidification and heating, thereby providing moist, warm air to the patient in cold or dry environments.

[0048] One end of the handle 40 is connected to the outlet pipe 32 of the humidification tank 30; by transmitting the humidified airflow to the handle 40 through the outlet pipe 32, on the one hand, the effective transmission of the pulsed airflow from the inside of the device to the user's mouth is achieved, and on the other hand, the discomfort of the patient's respiratory system is improved by humidifying the airflow, thereby enhancing the treatment comfort.

[0049] The medicine chamber structure 10 is arranged on the air inlet pipe 31 and is openably and closably connected to the air inlet pipe 31. Specifically, the connecting tube body 11 is arranged on the air inlet pipe 31, and the medicine chamber 12 and the sensor assembly 13 are connected to the air inlet pipe 31 via the connecting tube body 11. The compressed air flow in the air inlet pipe 31 flows at a high speed, so that the medicine in the medicine chamber 12 is atomized and flows out from the drug delivery hole 123 due to the negative pressure, and follows the compressed air flow into the humidification tank 30, and may be partially dissolved and mixed into the water in the humidification tank 30. When the heating base heats the water in the humidification and heating chamber, the water and the mixed medicine are vaporized together, so that the air flow output from the air outlet pipe 32 not only contains moist and temperature-appropriate water vapor, but also carries the drug components in the form of tiny evaporated droplets.

[0050] Furthermore, compared to traditional solutions, where the drug reservoir 12 is located inside the handle 40, the liquid drug particles do not undergo sufficient heating and humidification before entering the patient's mouth, resulting in the patient potentially inhaling cooler, drier drug particles, reducing treatment comfort and drug absorption efficiency. By placing the drug reservoir 12 on the air inlet pipe 31, the humidification tank 30 allows the drug to evaporate and heat up along with the water after being atomized or dissolved. The humidified and heated airflow output through the air outlet pipe 32 is fully loaded with drug components. When it enters the handle 40 and is ultimately delivered to the patient's mouth, the atomized drug is in a suitable temperature and moist state, reducing irritation and discomfort to the user and facilitating effective drug absorption by the patient, thus meeting the dual needs of drug delivery and gas humidification and heating in various respiratory therapy scenarios.

[0051] In summary, the present application provides a drug reservoir structure and a pulse respiratory therapy device, wherein the drug reservoir structure includes: a connecting tube body, the connecting tube body having an external end and a functional end that are relatively arranged, and an inner tube located between the external end and the functional end; a drug reservoir, the drug reservoir being arranged on the functional end and communicating with the inner tube of the connecting tube body; and a sensor assembly, the sensor assembly being arranged on the functional end and communicating with the inner tube of the connecting tube body; wherein the drug reservoir has a drug reservoir axis, the connecting tube body has a tube body axis, and the drug reservoir axis is arranged at an angle to the tube body axis. By arranging the drug reservoir and arranging the sensor assembly on the functional end of the connecting tube body, and arranging the drug reservoir axis at an angle to the tube body axis, in the pulse respiratory therapy device, the drug can be delivered and atomized at a location closer to the humidification and airflow generation point. At the same time, the synchronous arrangement of the sensor assembly provides conditions for real-time detection and adjustment of the drug delivery process, overcoming the shortcomings of traditional terminal drug reservoirs that cannot humidify, adjust drug concentration, or perform dynamic monitoring.

[0052] It should be understood that the application of this application is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
