Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a sputum expectorant capable of increasing the inhalation and exhalation flow rate. Background Art

[0002] In clinical medical treatment, timely and effective expectoration is crucial for patients who have difficulty coughing up sputum due to various reasons. Difficulty in expectoration is common in many diseases, such as patients with chronic obstructive pulmonary disease, whose respiratory tract secretions increase and become viscous due to long-term inflammatory stimulation, making them difficult to cough up. In stroke patients, due to damaged neurological function, the neural signal transmission that controls the respiratory and cough muscles is abnormal, resulting in weak coughs and inability to effectively expectorate. In addition, elderly and frail patients, as they age, their respiratory muscles weaken and the movement function of respiratory cilia declines, and they also face the problem of difficulty in expectoration. If sputum is not discharged in time, it will cause a series of serious consequences. First, the accumulation of sputum in the respiratory tract will block the airway and affect gas exchange, causing symptoms such as difficulty breathing and hypoxia in patients, which can even be life-threatening in severe cases. Second, sputum is a good culture medium for bacteria. Long-term retention can easily breed bacteria, cause lung infections, aggravate the patient's condition, prolong hospitalization, and increase medical costs. At present, expectoration machines are often used in clinical practice to solve the problem of patients' difficulty in expectoration.

[0003] For example, application number: CN202211651949.9 involves a new type of expectorant machine, which relates to the technical field of medical devices for assisting expectoration, including a main body, a collection device is provided on one side of the main body, a sterilization structure is fixedly installed above the main body, a handle is provided above the sterilization structure, a high-temperature system is fixedly installed on one side of the main body, a cleaning device is provided on one side of the high-temperature system, a hub is provided at the bottom of the main body, a fan is provided on one side of the sterilization mechanism, and a solenoid valve is provided on one side of the fan. This invention collects and processes the expectorant when the expectorant is used, which is convenient for patients to use and improves the practicality of the machine. When in use, the patient flows the expectorated sputum into the collection chamber through the entrance, and at least one interlayer cavity for storing preservation liquid is provided on the wall of the collection chamber. There are a fan and a solenoid valve inside the main body, and the fan and the solenoid valve cooperate to alternately output positive and negative pressure to expel sputum in the patient's airway.

[0004] However, there are still some deficiencies in the design of current cough machines: First, the suction airflow speed in the expectorant uses a preset fixed value. During a single suction process, the airflow speed cannot be accurately adjusted according to the real-time experience of different patients, making it difficult to quickly and effectively induce patients to cough up sputum, resulting in prolonged coughing time and increased patient discomfort. Secondly, although the sputum discharged by the patient can flow into the collection tube through the mask, some sputum still remains inside the mask. If it is not cleared in time, it will not only breed bacteria, but also cause physical discomfort to the patient, affecting the user experience. Summary of the Invention

[0005] In response to the above problems, one purpose of the present invention is to remedy these shortcomings, and more specifically to provide a cough machine that increases the inhalation and exhalation flow rate, enabling patients to adjust the speed of the inhalation and exhalation flow according to their own feelings, thereby improving the efficiency and comfort of expectoration, and can isolate the discharged sputum in time without contaminating the inner wall of the mask.

When the patient feels that the sputum cannot be discharged due to insufficient suction force or too slow airflow, the movable plate is pulled to one side to disengage the block from the limiting groove and lose the limiting effect on the piston rod. The patient can pull the piston rod by himself according to his own feeling. While moving the piston rod, the air pressure inside the mask can be adjusted, thereby solving the problem that the sputum cannot be sucked out due to insufficient suction. In addition, by quickly moving the piston rod, the speed of the airflow inside the mask can be effectively increased, which can be more conducive to stimulating the discharge of sputum.
