Description

Technical Field

[0001] This utility model relates to the technical field of lung function testing equipment, and in particular to a lung function pulse oscillation testing structure that is easy to assemble and disassemble. Background Technology

[0002] Pulmonary function tests are one of the necessary examinations for respiratory diseases. Pulse oscillation is one of the non-invasive, non-force-dependent tests in pulmonary function tests that measures the mechanical properties of the respiratory system, such as airway resistance. Its testing principle is based on forced oscillation technology, which involves applying an external oscillation wave (pressure signal) to the respiratory system during natural, calm breathing and measuring the corresponding flow rate change produced by the respiratory system under the oscillation pressure signal. The ratio of oscillation pressure to flow rate is the respiratory system impedance.

[0003] Currently, when performing pulmonary function tests on patients, they first need to sit in a standard sitting posture, use a nose clip to clamp their nose, and place their mouth on the mouthpiece at the end of the airway on the testing device. Then, following the doctor's instructions, they need to inhale and exhale at different times and frequencies. During this process, patients need to accurately cooperate with the doctor's instructions to complete multiple pulmonary function tests in sequence. However, for the pulse oximetry test, only calm breathing is required. This test does not require forceful or shallow, rapid breathing, so it is suitable for a wide range of people, especially those who cannot complete traditional pulmonary function tests such as spirometry, such as the elderly, children, and critically ill patients. Furthermore, it provides a wealth of respiratory physiological indicators (viscous resistance, elastic resistance, and inertial resistance) to provide a deeper understanding of functional changes in respiratory diseases, showing promising application prospects.

[0004] Current pulmonary function tests are mainly conducted using large, specialized pulmonary function testing equipment. There is no independent pulse oscillation test structure. Although large, specialized pulmonary function testing equipment can test multiple functions simultaneously, its structure is more complex, and the disassembly and assembly steps during cleaning and disinfection are cumbersome, which is inconvenient for users who only need pulse oscillation testing.

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0022] Please see Figures 1-4 A conveniently detachable pulmonary function pulse oscillation test structure includes an airflow valve 10, a pressure and flow rate testing component 20, and a pulse oscillation unit 30. One end of the airflow valve 10 is a breathing end 101, and the other end is an adjustment end 102. A flat end face 11 is formed at the breathing end 101 away from the adjustment end 102, and an intersecting first adjustment surface 12 and second adjustment surface 13 are formed at the adjustment end 102 away from the breathing end 101. An airway 14 is formed within the airflow valve 10, extending from the flat end face 11 to the first adjustment surface 12 and the second adjustment surface 13. A breathing interface 111 is detachably installed on the flat end face 11 corresponding to the airway 14, and the pressure and flow rate testing component 20 is detachably installed on the breathing interface 111. A pulse input interface 121 is detachably installed on the first adjustment surface 12 corresponding to the airway 14, and the pulse oscillation unit 30 is detachably installed on the pulse input interface 121. A ventilation port 131 is opened on the second adjustment surface 13 corresponding to the airway 14.

[0023] Furthermore, in this embodiment, the pressure and flow rate testing component 20 includes a pressure and flow rate synchronization testing unit 21 detachably mounted on the breathing interface 111 and a breathing nozzle 22 detachably mounted on the pressure and flow rate synchronization testing unit 21. The breathing nozzle 22 is connected to the breathing interface 111 through the pressure and flow rate synchronization testing unit 21. When breathing with the mouth in the breathing nozzle 22, the respiratory system generates a corresponding flow rate change as the pulse oscillation is superimposed.

[0024] Furthermore, in this embodiment, the pulse oscillation unit 30 includes a support base 31 inserted into the pulse input interface 121, a protective shell 32 detachably installed on the support base 31, and a pulse pressure source 33 disposed in the protective shell 32. The support base 31 and the protective shell 32 form a channel 301 communicating with the pulse input interface 121, so that the pulse pressure source 33 can superimpose pulse oscillation into the airway 14 through the channel 301.

[0025] Furthermore, the protective shell 32 is equipped with a data transmission unit, which is electrically connected to the pressure and flow synchronization test unit 21. After the pressure and flow synchronization test unit 21 tests the flow and pressure signals after superimposed pressure pulse signals, the data transmission unit uploads the pressure and flow signals to the processing software, PC or APP through data communication. The processing software, PC or APP processes and analyzes the flow and pressure signals, and through spectrum analysis, obtains a continuous signal of 4-40HZ, and converts it into the corresponding human airway resistance lung function.

[0026] Furthermore, the protective shell 32 is equipped with a control unit for controlling the opening and closing of the circuit and the driving of the pulse pressure source 33.

[0027] Furthermore, the pulse oscillation unit 30 includes, but is not limited to, using a horn, a motor, or high-pressure gas as the pulse pressure source 33; in this embodiment, the pulse pressure source 33 is a horn. The pressure pulse signal generates a test signal through force. The test signal can generate a single sine wave, a composite sine wave, or a triangular / rectangular pulse wave. The test signal is superimposed on the human respiratory tidal waveform to generate a corresponding flow signal.

[0028] Furthermore, in this embodiment, a pressure regulating cover 40 that can be opened and closed relative to the air vent 131 is detachably installed on the second regulating surface 13 to regulate the air pressure in the airway 14.

[0029] Furthermore, in this embodiment, the pressure regulating cover 40 has a bottom cover 41 detachably mounted on the inner side of the airflow valve 10 and a top cover 42 hinged to the bottom cover 41 and capable of opening and closing relative to the bottom cover 41. The top cover 42 is provided with a filter membrane 43 corresponding to the air vent 131. When the top cover 42 is closed relative to the bottom cover 41, the filter membrane 43 seals the air vent 131, thereby increasing the required air pressure when the air passage 14 vents to the outside, thus meeting the needs of different users.

[0030] Furthermore, in this embodiment, the breathing end 101 is rectangular, and the adjustment end 102 is an isosceles triangle with the same width as the breathing end 101, which facilitates the overall assembly and disassembly of the pulmonary function pulse oscillation test structure.

[0031] Understandably, the method of using this utility model's conveniently disassembled and assembled pulmonary function pulse oscillation test structure is as follows: When the pulse pressure source 33 is turned on and pulse oscillations are superimposed into the airway 14, the pulse oscillation test item for pulmonary function testing can be realized; when the pulse pressure source 33 is not turned on, it can be converted into a traditional pulmonary function test. Thus, while not only supporting airway 14 resistance testing in tidal breathing mode, it innovatively adds pulse oscillation airway 14 resistance testing in forced ventilation / maximum ventilation mode, and the overall structure is simple and compact, facilitating disassembly and cleaning.

[0032] In summary, the pulmonary function pulse oscillation test structure of this utility model, which is easy to disassemble and assemble, can realize the pulse oscillation test of pulmonary function through the cooperation between the airflow valve 10, the pressure and flow test component 20 and the pulse oscillation unit 30. At the same time, the overall structure is simple and compact, easy to disassemble and clean, and more convenient to use.

[0033] Any combination of different embodiments of this utility model, provided it does not violate the inventive concept of this utility model, shall be considered as the disclosure of this utility model; any simple modifications to the technical solution and any combination of different embodiments within the scope of the inventive concept of this utility model, without violating the inventive concept of this utility model, shall be within the protection scope of this utility model.
