[0021] Referring to FIGS. 1 to 3, a first embodiment of the present application provides a drug chamber structure 10 for use in a pulse respiration therapy device. The drug chamber structure 10 includes a connecting pipe body 11, a drug chamber 12, and a sensing assembly 13. The connecting pipe body 11 has an externally connected end 111 and a functional end 112 provided opposite to each other, and an inner cylinder 113 located between the externally connected end 111 and the functional end 112, which can facilitate docking with the air flow passage of the pulse respiration therapy device. The drug chamber 12 is provided at the functional end 112 and communicates with the inner cylinder 113 of the connecting pipe body 11, having higher flexibility and timeliness in terms of drug diffusion, mixing, and temperature adjustment. Since the drug chamber 12 directly communicates with the inner cylinder 113, the drug flows efficiently inside the pipe body together with the pulse air flow, reducing the retention and waste of the liquid medicine. The sensing assembly 13 is provided at the functional end 112 and communicates with the inner cylinder 113 of the connecting pipe body 11, capable of monitoring in real time during the drug delivery process and detecting indicators such as, for example, liquid medicine concentration, flow rate, or temperature. When the sensing assembly 13 detects a deviation from a preset value, it can be automatically or manually adjusted with respect to the device. Here, the drug chamber 12 has a drug chamber axis 14, the connecting pipe body 11 has a pipe body axis 15, and the drug chamber axis 14 and the pipe body axis 15 are provided at an included angle α, thereby reducing the precipitation and dead space of the liquid medicine while preventing the liquid medicine from scattering disorderly in the axial direction.

[0022] In some embodiments, the drug chamber axis 14 and the pipe body axis 15 are provided at an included angle α of 75° to 85°. Furthermore, it can effectively relieve the accumulation or scattering of the liquid medicine due to a single axial flow, and can deliver and atomize the liquid medicine smoothly together with the pulse air flow. On the other hand, due to the inclination angle, the sensing assembly 13 provides a more stable fluid environment for measuring the drug flow and concentration change, further improving the detection accuracy and response speed of indicators such as drug concentration or temperature, and considering the compactness of the structure and the ease of operation.

[0023] In some embodiments, the pharmacy chamber 12 further comprises a pharmacy body 120, an opening adjustment member 124, and a valve head 125, wherein the pharmacy body 120 is sequentially provided with a body section 121 and a diameter-reducing section 122 along the axial direction, the diameter-reducing section 122 is connected to the functional end 112, and the diameter-reducing section 122 is provided with a drug delivery hole 123, and the diameter-reducing section 122 is directly connected to the functional end 112, and the diameter-reducing section 122 is provided with a drug delivery hole 123, and during the process of the drug moving from a wide conduit to a narrow conduit, it is buffered by the flow velocity gradient. This reduces vortices and turbulence caused by abrupt changes in the cross-section, enables convergence and orientation of the drug flow path over a short distance, facilitates subsequent humidification or airflow mixing, is suitable for dispensing small amounts of drug under pulsed airflow, reduces drug waste and clogging risk, the opening adjustment member 124 is connected to the main body section 121, the valve head 125 is provided at the end of the opening adjustment member 124 closest to the drug dispensing hole 123, and the amount of drug dispensed is controlled by adjusting the gap between the valve head 125 and the drug dispensing hole 123 by adjusting the opening adjustment member 124. The opening adjustment member 124 is attached to the main body section 121 and forms a mating relationship with the valve head 125, which is located near the drug delivery hole 123. It is used to change the gap between the valve head 125 and the hole wall. When it is necessary to increase the drug dosage, the opening adjustment member 124 can be rotated or moved to increase the gap between the valve head 125 and the drug delivery hole 123, thereby increasing the drug flow rate per unit time. Conversely, by decreasing the gap, the drug drip rate or flow rate can be reduced, or the drug delivery passage can be closed. Considering the adjustable range and convenient operation, the clinical staff or system control unit can flexibly set the dosage to better suit the individual treatment needs of the patient.

[0024] In some embodiments, the axial cross-sectional shape of the inner wall of the reduced diameter section 122 is set to a steepest descent curve, which forms a smoother, faster, and more controllable transmission path during drug flow, reducing turbulence and drug stagnation caused by the rapid contraction of the opening, while allowing the drug delivery hole 123 and the valve head 125 to cooperate more precisely, enabling changes in dosage with small angular rotations of the adjustment spool.

[0025] In some embodiments, the valve head 125 is provided as a flexible valve head 125, and the axial cross section of the valve head 125 is set to a steepest descent curve. By employing a valve head 125 made of a flexible material, a tighter sealing contact can be formed under the combined action of compressed airflow and minute amounts of chemical, which helps maintain a precise minute gap between the reduced diameter section 122 and the chemical delivery hole 123, making it less likely for rigid valve heads 125 to become clogged or have excessive gaps. On the other hand, the steepest descent curve axial cross section helps the chemical to pass quickly and smoothly through the section near the valve head 125 at an optimized flow velocity when the flexible valve head 125 is impacted by the fluid, which not only avoids the accumulation or backflow of the chemical due to flow field turbulence but also makes the operation of the adjustment spool more sensitive to the control of the chemical delivery amount.

[0026] In some embodiments, the drug delivery hole 123 sequentially includes a transition hole section, a first rapid descent section, a straight hole section, and a second rapid descent section along the axial direction, where the drug is first gently guided in the transition hole section after entering the drug delivery hole 123, then gradually transitions to the first rapid descent section for rapid and stable flow, and after the drug passes through the straight hole section, the second rapid descent section provides an acceleration output symmetrical to the first rapid descent section, helping to reduce turbulence or accumulation due to abrupt changes in cross-section. The transition hole section is used to connect the reduced diameter section 122 and the first rapid descent section, where the first and second rapid descent sections are provided symmetrically with respect to the straight hole section, and the hole walls in the axial cross-sections of the first and second rapid descent sections are all set to a steepest descent curve, so that under the negative pressure of the compressed airflow, the drug or atomized droplets pass through the hole walls in almost the minimum time, avoiding the appearance of large eddy or dead space zones during acceleration and deceleration. At the same time, the symmetrical layout can maintain consistency in flow characteristics during the fine-tuning process of the valve head 125 or adjustment member, thereby improving the controllability and stability of drug dispensing.

[0027] In some embodiments, the opening adjustment member 124 is configured as a wing nut, with a screw hole 1211 provided in the main body section 121, one end of the wing nut connected to the screw hole 1211 and protruding from the main body section 121, and the other end of the wing nut connected to the valve head 125. By rotating the wing nut in the main body section 121, the screw is controlled to move along the axial direction of the screw hole 1211, thereby changing the corresponding gap between the valve head 125 and the drug delivery hole 123. The butterfly design of the wing nut end makes manual adjustment more convenient and intuitive, allowing for quick fine adjustments to be easily made from the control panel or at the patient's bedside, without the use of specialized tools, and allowing for flexible changes in drug delivery volume according to drug delivery needs, improving usability and adjustment accuracy.

[0028] In some embodiments, the opening adjustment member 124 includes a servo motor and an adjustment screw, the servo motor being located at one end of the main body section 121 away from the reduced diameter section 122, one end of the adjustment screw being connected to the output shaft of the servo motor and the other end to the valve head 125. The servo motor is known to drive the adjustment screw to move precisely in the axial direction after receiving a command (from the control panel or automatic detection data), thereby adjusting the gap between the valve head 125 and the drug delivery hole 123, enabling automatic adjustment and control of the drug delivery amount. Compared to conventional manual rotation or fixed adjustment methods, servo motor drive can not only provide finer step accuracy but can also be dynamically corrected in combination with real-time detection results from the sensing assembly 13, significantly improving the accuracy and intelligence level of drug delivery in the pulsed respiratory therapy device.

[0029] In some embodiments, the sensing assembly 13 is detachably connected to the functional end 112 and includes a pressure sensor, a temperature sensor, and a humidity sensor. Designing the sensing assembly 13 to be detachable ensures that it can be easily removed, replaced, or calibrated during routine maintenance or troubleshooting, and also allows the user to quickly switch between different levels, accuracy, or types of sensing elements according to actual needs or treatment processes. Furthermore, by simultaneously placing pressure, temperature, and humidity sensors in the sensing assembly 13, the airflow and drug mixture environment entering the drug chamber 12 can be detected in multiple dimensions. If a sensing indicator falls outside a predetermined range, the device can issue an alarm in a timely manner, or, in cooperation with the adjustment opening adjustment member 124 and valve head 125, dynamic control of the drug delivery process can be achieved, effectively improving the safety and applicability of the pulsed respiratory therapy device. It should be noted that the sensing assembly 13 enables real-time monitoring of compressed airflow and drug by the sensor assembly 13 through the opening of the functional end 112.

[0030] In some specific embodiments, before pulse therapy, the drug is first injected into the drug chamber 12 of the drug chamber structure 10, then the connecting tube 11 of the drug chamber structure 10 is connected to the pulse therapy device, the opening adjustment member 124 is adjusted as needed to adjust the gap between the valve head 125 and the drug delivery hole 123, and the amount of drug delivered is controlled. The sensing assembly 13 monitors data such as the flow velocity, temperature, and amount of drug delivered of the compressed airflow, and the gap between the valve head 125 and the drug delivery hole 125 can be adjusted in real time. By providing the drug chamber 12 and the sensing assembly 13 at the functional end 112 of the connecting tube 11, and aligning the drug chamber axis 14 and the tube axis 15 at a narrow angle, the drug chamber structure 10 does not need to be located in the axial direction of the tubing of the pulse respiratory therapy device, and the drug can be delivered and atomized at a position closer to humidification and airflow generation. Simultaneously, by providing the sensing assembly 13, conditions are created for real-time detection and adjustment of the drug delivery process, overcoming the shortcomings of conventional terminal drug chambers, such as the inability to humidify, adjust drug concentration, or perform dynamic monitoring.

[0031] Referring further to Figure 4, the second embodiment of this application provides a pulse therapy device comprising a therapy device body 20, a humidifying canister 30, a handle 40, and a drug chamber structure 10 provided in the first embodiment of this application, which enables efficient humidification and heating of compressed airflow, thereby improving therapeutic comfort and the practicality of the device.

[0032] The treatment device body 20 is provided with a canister mounting section 21 and a compressed air passage 22. By providing the canister mounting section 21 on the treatment device body 20, the humidifying canister 30 can be integrally attached to the treatment device body 20, the attachment of the humidifying canister 30 is made more stable, a reliable air passage communication path is provided for airflow transport from the compressed air source to the humidifying canister 30, and the airtightness and operational stability of the entire device can be ensured.

[0033] The humidifying canister 30 is detachably mounted on the canister mounting section 21 and is equipped 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, which not only facilitates cleaning and maintenance of the humidifying canister 30 but also facilitates replacement or upgrade of the humidifying device according to different treatment needs, effectively avoiding the problems of conventional external humidifying devices, such as their complex structure and high maintenance costs. At the same time, the air inlet pipe 31 of the humidifying canister 30 is connected to the compressed air passage 22, allowing compressed air to smoothly enter the humidifying canister 30 for humidifying and heating treatment, providing patients with moist, warm air in cold or dry environments.

[0034] One end of the handle 40 is connected to the air outlet pipe 32 of the humidifying canister 30, and the humidified airflow is transmitted to the handle 40 through the air outlet pipe 32, thereby enabling effective transmission of pulsed airflow from inside the device to the user's mouth. At the same time, the humidified airflow improves the patient's respiratory discomfort and enhances treatment comfort.

[0035] The aforementioned drug chamber structure 10 is provided in the air inlet pipe 31 and is provided in openable and closable communication with the air inlet pipe 31. Specifically, the connecting pipe 11 is provided in the air inlet pipe 31, the drug chamber 12 and the sensing assembly 13 are connected to the air inlet pipe 31 via the connecting pipe 11, a compressed airflow flows at high speed in the air inlet pipe 31, the drug in the drug chamber 12 is atomized by negative pressure and flows out from the drug delivery hole 123, enters the humidifying canister 30 together with the compressed airflow, a portion dissolves and mixes with the water in the humidifying canister 30, and when the heating base heats the water in the humidifying heating chamber, the water turns into vapor together with the mixed drug, and the airflow output from the air outlet pipe 32 contains not only moist water vapor at the appropriate temperature, but also drug components that exist in the form of minute evaporated droplets. Compared to conventional solutions, where the drug chamber 12 is located inside the handle 40, the drug liquid particles do not receive sufficient heating and humidification before entering the patient's mouth, potentially causing the patient to inhale colder, drier drug particles, reducing therapeutic comfort and drug absorption efficiency. By placing the drug chamber 12 in the air inlet pipe 31, the humidifying canister 30 evaporates and heats the drug along with water after atomization or dissolution. The humidified heated airflow output from the air outlet pipe 32 contains sufficient drug components, which enter the handle 40 and are finally delivered to the patient's mouth. As a result, the atomized drug is in an optimally warm and moist state, reducing irritation and discomfort to the user, promoting effective drug absorption by the patient, and meeting the dual needs of drug delivery and gaseous humidification and heating in various respiratory therapy scenarios.

[0036] In summary, this application provides a drug chamber structure and a pulsed respiratory therapy device, the drug chamber structure comprising a connecting tube having an outer end and a functional end facing each other, and an inner cylinder located between the outer end and the functional end, a drug chamber provided at the functional end and communicating with the inner cylinder of the connecting tube, and a sensing assembly provided at the functional end and communicating with the inner cylinder of the connecting tube, wherein the drug chamber has a drug chamber axis, the connecting tube has a tube axis, and the drug chamber axis and the tube axis are set at a narrow angle. By providing the drug chamber at the functional end of the connecting tube and positioning the sensing assembly therein, and by setting the drug chamber axis and the tube axis at a narrow angle, the drug can be delivered and atomized in the pulsed respiratory therapy device at a position closer to humidification and airflow generation. At the same time, by simultaneously providing the sensing assembly, conditions are provided for real-time detection and adjustment of the drug delivery process, overcoming the shortcomings of conventional terminal drug chambers that cannot humidify, adjust drug concentration, or dynamically monitor.
