Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a clinical pulmonary function rehabilitation device. Background Technology
[0002] Chronic obstructive pulmonary disease (COPD), commonly known as COPD, is a chronic inflammatory lung disease characterized by airflow limitation, which typically worsens over time and is associated with damage to the airways and alveoli. Patients primarily experience chronic cough, sputum production, shortness of breath, and difficulty breathing, symptoms that may gradually intensify over time. To aid COPD patients in pulmonary rehabilitation, specially designed breathing exercises are available. These devices utilize a series of scientifically designed breathing exercises to strengthen respiratory muscles and improve respiratory efficiency, aiming to alleviate breathing difficulties and improve quality of life. These devices guide patients through various breathing exercises such as pursed-lip breathing, diaphragmatic breathing, and deep breathing. These exercises help increase lung capacity, promote oxygen absorption and carbon dioxide expulsion, thereby improving blood oxygen saturation. Simultaneously, COPD breathing exercises also help patients cough and expectorate effectively, reducing airway obstruction and preventing lung infections.
[0003] Box breathing is a rhythmic breathing exercise that helps improve lung function and promote relaxation by controlling the rhythm of breathing. It involves slowly inhaling deeply through the nose while silently counting to four, then holding the breath and silently counting to four again. Next, slowly exhale through the mouth while silently counting to four, and finally hold the breath again while silently counting to four, completing one cycle. This process can be repeated multiple times as needed, requiring a certain level of self-discipline from the patient. To assist patients in performing this breathing exercise to improve lung function, a pulmonary rehabilitation device is needed to assist with this training. This device can assist patients in performing the "inhale-hold-exhale-hold" cycle and allows for adjustments to the inhalation, holding, and exhalation times to ensure optimal training results. It also needs an emergency mechanism to prevent discomfort during the breathing exercise; and the device should be easy to use and wear without the patient's hands. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model designs a clinical pulmonary function rehabilitation exercise device. The device is based on the box-type breathing exercise method. Two rotors are controlled by a servo motor. With the cooperation of the connecting shell, different channels are connected. The servo motor rotates 90° each time, and four rotations constitute one breathing cycle, thereby realizing the box-type training process of "inhalation-breath-exhalation-breath ...
[0005] The device is easy to wear and operate. It is fixed to the patient's face via two ear loops, eliminating the need for the patient to hold it.

Considering that everyone's physical condition is different and unexpected situations may occur during breath-holding or inhalation training, the device is specially equipped with an emergency button. Pressing this button mechanically opens the device's inhalation and exhalation channels simultaneously, avoiding any possible discomfort to the patient.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0032] Example 1
[0033] This utility model discloses a clinical pulmonary function rehabilitation exercise device. The core of the device lies in its inhalation adjustment component, which is used in conjunction with a nasal sleeve, a mouthpiece, and ear hooks. The nasal sleeve is located at the upper end of the inhalation adjustment component and is fixedly connected to it, ensuring stability and sealing during inhalation. The ear hooks are fixed to both ends of the nasal sleeve, allowing the device to be securely fixed to the user's face without the need for handheld use, thus enabling the user to focus more on the breathing training itself. The mouthpiece is located at the lower end of the inhalation adjustment component and is fixedly connected to it. It not only provides a convenient exhalation channel for the user but also encourages the user to perform diaphragmatic breathing exercises by inhaling through the nose and exhaling through the mouth.
[0034] The inhalation and exhalation assembly includes a connecting shell, a first rotor, a second rotor, a connecting block, a first end plate, a second end plate, an emergency stop button, a first spring, a second spring, a synchronous shaft sleeve, and a motor. The connecting shell has a cylindrical slot inside and slots on the outside that communicate with the internal slots, including a first inhalation port and a first exhalation port, as well as a second inhalation port and a second exhalation port positioned opposite each other. This allows the device to open and close different airways through the rotation of the rotors, controlled by the motor, simulating a box-type breathing training process of "inhalation-breath-holding-exhalation-breath-holding."
[0035] Both the first and second rotors contain L-shaped pipes connected by a connecting block, creating a 90° angle between the L-shaped pipes. This design ensures that the inhalation and exhalation pipes can be opened and closed separately during rotor rotation. Springs provide necessary support for the rotors, ensuring their stability during rotation. The fixed motor provides power to the entire device, and precise rotor control is achieved by controlling the motor's rotation.
[0036] The emergency button is designed with human-centered considerations in mind. It is fixed on the synchronous shaft of the first rotor, so that in an emergency, the user can quickly press the button to open the air intake and exhaust pipes of the device immediately and simultaneously, thereby ensuring the user's comfort and safety. After releasing the emergency button, the device can be restored under the elastic force of the first and second springs.
[0037] Example 2
[0038] In this embodiment, the motor can be a servo motor or a stepper motor. Through program settings, it can be ensured that the motor rotates 90° each time and that the L-shaped pipes of the first rotor and the second rotor are aligned with the inhalation port and the exhalation port.
[0039] The first rotor and the second rotor rotate under the drive of the motor shaft, and the motor rotates 90° each time, resulting in four states.
[0040] When the device moves to Figure 7 In this state, one end of the second rotor L-shaped tube is connected to the first inhalation tube, and the other end of the second rotor L-shaped tube is connected to the second inhalation tube. At this time, the exhalation tube is closed, and the user can inhale through the nasal cannula.
[0041] When the device moves to Figure 8 In this state, both the inhalation and exhalation channels are closed, and the user can neither inhale nor exhale.
[0042] When the device moves to Figure 9 In this state, one end of the first rotor L-shaped tube is connected to the first exhalation tube, and the other end of the first rotor L-shaped tube is connected to the second exhalation tube. At this time, the inhalation tube is closed, and the user can exhale through the mouthpiece.
[0043] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described.
