For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] Please refer to Figures 1 to 3The first embodiment of the present application provides a medicine chamber structure 10 for a pulse breathing therapeutic device, wherein the medicine chamber structure 10 comprises a connecting tube body 11, a medicine chamber 12 and a sensor assembly 13; the connecting tube body 11 has an external end 111 and a functional end 112 arranged opposite to each other, and an inner cylinder 113 located between the external end 111 and the functional end 112, which can conveniently connect to the airflow path of the pulse breathing 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 drug 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 tube 113 of the connecting tube body 11, so as to facilitate 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 arranged 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 medicine chamber axis 14 and the tube body axis 15 are arranged at an angle α of 75°-85°. On the one hand, the accumulation or splashing of the drug solution caused by the single axial flow can be effectively alleviated, so that the drug solution can be transported and atomized more smoothly with the pulse airflow; on the other hand, the inclination angle also provides a more stable fluid environment for the sensor component 13 to measure the drug flow and concentration change, thereby further improving the detection accuracy and response speed of indicators such as drug concentration or temperature, and taking into account both compact structure and user-friendly operation.

[0037] In some embodiments, the medicine bin 12 further includes: a medicine bin body 120, an opening adjustment member 124 and a valve head 125, wherein the medicine bin body 120 is provided with a main section 121 and a reduced diameter section 122 in sequence along the axial direction, wherein the reduced diameter section 122 is connected to the functional end 112, and the reduced diameter section 122 is provided with a drug delivery hole 123; the reduced diameter section 122 is directly connected to the functional end 112, and the drug delivery hole 123 is provided on the reduced diameter section 122, so that the drug solution is buffered by the flow velocity gradient during the transition from a wide pipe to a narrow pipe, thereby reducing the sudden change caused by the sudden change. The eddy current or turbulence caused by the cross-section can be reduced, and the convergence and orientation of the drug liquid 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 solution flowing through per unit time. On the contrary, reducing the gap can reduce the dripping rate or flow rate of the drug solution, or even shut off the drug delivery passage. This takes into account both the adjustable range and the ease 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 controllable transmission path when the drug solution flows, reducing turbulence or drug solution 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 a small angle rotation of the regulating valve core.

[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 compliant sealing contact can be formed under the combined action of the compressed airflow and a trace amount of liquid medicine, which helps to maintain a precise micro-gap between the reduced diameter section 122 and the dosing 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 of the most rapid drop curve 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, which not only avoids the accumulation or backflow of the liquid medicine due to the turbulence of the flow field, but also makes the operation of adjusting the valve core more sensitive to the control of the dosing amount.

[0040] In some embodiments, the dosing hole 123 includes a transition hole section, a first speed drop section, a straight hole section, and a second speed drop section in the axial direction, so that the drug liquid is first smoothly guided in the transition hole section after entering the dosing hole 123, and then gradually transitions to the first speed drop section for rapid and stable flow; and when the drug liquid passes through the straight hole section, it realizes the accelerated output in the second speed drop section that is mirror-symmetrical with the first speed drop section, which is conducive to reducing the turbulence or accumulation caused by the sudden change of the 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, and the hole walls of the axial cross sections of the first speed drop section and the second speed drop section are both arranged as the most rapid drop curve; under the negative pressure of the compressed air flow, the drug liquid or atomized droplets pass through the hole wall in approximately the shortest time, avoiding the occurrence of a large range of eddy currents or dead angles during acceleration or deceleration. At the same time, the symmetrical layout can also maintain the consistency of flow characteristics during the fine-tuning process of the valve head 125 or the adjusting member, and improve the controllability and stability of the drug liquid distribution.

[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, and the other end of the butterfly screw is connected to the valve head 125. The butterfly screw is controlled to move axially along the threaded hole 1211 by rotating the butterfly screw on the main body section 121, so that the gap between the valve head 125 and the drug delivery hole 123 changes accordingly; the butterfly design at the end of the butterfly screw makes manual adjustment more convenient and intuitive, and is also easy to quickly fine-tune on the operation panel or at the patient's bedside, so that the drug delivery amount can be flexibly changed according to the drug delivery needs without the need for professional tools, taking into account both 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 disposed 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 regulation of the drug delivery amount; compared with the traditional manual rotation or fixed adjustment method, the servo motor drive can not only provide more delicate stepping 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 instrument in terms of 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 the user can quickly switch between sensor elements of different levels, precisions, or types according to actual needs or treatment procedures. Furthermore, by configuring pressure, temperature, and humidity sensors in the sensor component 13 at the same time, the airflow entering the medicine bin 12 and the mixed environment of the drug liquid can be detected in multiple dimensions. When a certain sensor indicator deviates from the preset range, the device can promptly give an alarm or link 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 breathing therapy device. It should be noted that the sensor component 13 can realize real-time monitoring of compressed gas and drugs by the sensor component 13 by making a hole on the functional end 112.

[0044] In some specific embodiments, before pulse therapy is performed, the drug is first injected into the drug chamber 12 of the drug chamber structure 10, and then the connecting tube body 11 of the drug chamber structure 10 is connected to the pulse therapy device, and then the opening adjustment member 124 is adjusted as needed to adjust the gap between the valve head 125 and the drug delivery hole 123, thereby controlling the drug delivery amount, and the flow rate, temperature, drug delivery amount and other data of the compressed air flow are monitored by the sensor component 13, and the gap between the valve head 125 and the drug delivery hole 125 is adjusted in real time. By arranging the drug chamber 12 and the sensor component 13 on the functional end 112 of the connecting tube body 11, and arranging the drug chamber axis 14 and the tube body axis 15 at an angle, in the pulse respiratory therapy device, the drug chamber structure 10 no longer needs to be installed on the axial direction of the pipeline of the pulse respiratory therapy device, so that the drug can be transported and atomized at a position closer to the humidification and airflow generation. 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, so that the installation of the humidification tank 30 is more stable, and a reliable air duct connection path is provided for the airflow from the compressed air source to the humidification tank 30, thereby ensuring the overall air tightness and operation stability of the equipment.

[0047] The humidification tank 30 is detachably mounted on the tank body mounting portion 21. The humidification tank 30 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 the cleaning and maintenance of the humidification tank 30 and facilitates the replacement or upgrading of the humidification device according to different treatment needs, effectively avoiding the problems of complex structure and high maintenance cost of traditional external humidification devices. At the same time, the air inlet pipe 31 of the humidification tank 30 is connected to the compressed air passage 22, so that the compressed air flow can smoothly enter the humidification tank 30 for humidification and heating treatment, thereby providing moist and temperature-appropriate air flow for patients 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, 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 the humidified airflow, thereby enhancing the treatment comfort.

[0049] The medicine chamber structure 10 is arranged on the air inlet pipe 31, and can be connected to the air inlet pipe 31 in an openable and closable manner; 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 through the connecting tube body 11; the compressed airflow 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 airflow 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 airflow 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 with the traditional solution, the medicine chamber 12 is located inside the handle 40, and the liquid drug particles are not fully heated and humidified before entering the patient's mouth, which may cause the patient to inhale colder and drier drug particles, reducing the treatment comfort and drug absorption efficiency. By setting the medicine chamber 12 on the air inlet pipe 31, the humidification tank 30 allows the drug to evaporate and heat up together with water after being atomized or dissolved. The humidified and heated airflow output through the air outlet pipe 32 already fully carries the drug components. When it enters the handle 40 and is finally delivered to the patient's mouth, the atomized drug is in a suitable temperature and moist state, which reduces the stimulation and discomfort to the user, is more conducive to the patient's effective absorption of the drug, and meets the dual needs of drug delivery and gas humidification and heating in various respiratory treatment scenarios.

[0051] In summary, the present application provides a medicine bin structure and a pulse breathing therapeutic apparatus, wherein the medicine bin structure comprises: a connecting tube body, the connecting tube body having an external end and a functional end arranged relatively, and an inner tube located between the external end and the functional end; a medicine bin, the medicine bin is arranged on the functional end and communicated with the inner tube of the connecting tube body; a sensor assembly, the sensor assembly is arranged on the functional end and communicated with the inner tube of the connecting tube body; wherein the medicine bin has a medicine bin axis, the connecting tube body has a tube body axis, and the medicine bin axis is arranged at an angle with the tube body axis. By arranging a medicine bin on the functional end of the connecting tube body and arranging the sensor assembly, and arranging the medicine bin axis at an angle with the tube body axis, in the pulse breathing therapeutic apparatus, the drug can be transported and atomized at a position closer to the humidification and airflow generation location. 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 the traditional terminal medicine bin that cannot humidify, adjust the drug concentration or perform dynamic monitoring.

[0052] It should be understood that the application of the present application is not limited to the above examples.

All these improvements and changes should fall within the scope of protection of the claims attached to this application.
