1. Field of the Invention
The present invention relates to an electromagnetic powered sputum excretion system.
2. Background of the Invention
Chest physical therapy has a long history of clinical applications. It is very effective, and is among the standard of medical methods for improving airway mucus cleanup in various countries. The chest physical therapy comprises manual knocking on the back for sputum excretion, in vitro vibration machine for sputum excretion, but all of these suffer from many problems.
In recent years, vest type air pulse sputum excretion devices have also been developed and improved in foreign countries. The air pressure pulse machine repeatedly deflates and inflates two airbags which are fixed in front of the vest. Each application of pressure will force the air flow to quickly pass through the lobe, and promote the secretion of debris to fall from the lung wall and move to the oral cavity. Once the secretion of debris reaches the oral cavity, it can be discharged through the normal cough or vacuum suction. In this sputum excretion device, the operation is fully automated, and the standard parameter setting is adopted, which substantially overcomes drawbacks of the two methods mentioned in the previous paragraph. However, new problems are introduced as follow. Firstly, the fixed two-point anterior chest wall pulse can not beat the side and back of the thorax, and the effect of sputum excretion is poor for some patients. Secondly, once the treatment parameters have been set, the therapeutic procedure is performed in light of the standards completely, and is not interrupted even if it has induced the patient to cough, which may lead to risks like continuous coughing for a long time, consuming a lot of physical strength, and hyperventilation. In view of these problems, a new “intelligent all-chest high frequency vibration sputum excretion device” has been developed, which is described as follow.
As shown in
By adopting this intelligent all-chest high frequency vibration sputum excretion device, the sputum excretion method comprises the steps of:
a. fixing the pressure vest 8 to human chest 28 via linking tapes 14;
b. according to the user's conditions, regulating the frequency input end 22, the air pressure input end 23, and the timing input end 30 on the cover plate 7, and then turning on the electric-controlled switch 26;
c. making the electric motor 20 to transfer air to the pressure vest 8 according to a preset value;
d. importing air to inflate the pressure vest 8 for massaging the human chest 28, while detecting by the pressure sensor 2 the signal of pressure that the pressure vest 8 acts on the human chest 28;
e. comparing the detected pressure signal with the preset value, and then sending the signal to the air the pressure pulse regulator 17 and the pulse regulator 16 for regulating;
f. sending the regulated signal to the electric motor 20 and the air pressure compensator 21, so that the electric motor 20 transfers air to the pressure vest 8 according to the compensated signal;
e. stopping transferring the air if the coughing sensor 3 has detected a chest vibration frequency ≧3 times/10 seconds or the massaging last a time preset by the timing device, otherwise continuing to transfer the air.
During use, the pressure vest 8 is bound around the human chest 28, and the pressure vest 8 is arranged to closely bind the human chest via linking tapes 14. According to the user's conditions, the frequency input end 22, the air pressure input end 23, and the timing input end 30 are adjusted, and then the electric-controlled switch 26 is turned on. As a result, the electric motor 20 transfer air into the pressure vest 8 periodically via the hose 1 according to the set values. At the same time, the pressure sensor 2 and the coughing sensor 3 monitors the system in real time as follow.
1) When the pressure sensor 2 detects that the pressure of the pressure vest 8 does not match the preset pressure, the pressure sensor 2 sends a signal to the frequency voltage conversion circuit 15, so that the frequency voltage conversion circuit 15 transfers a signal to the pulse regulator 16. The pulse regulator 16 regulates the signal appropriately, and controls the electric motor 20 to transfer air to the pressure vest 8 connected with the hose 1. When the pressure sensor 2 detects the pressure signal matches the preset value, the pulse regulator 16 stops regulating, and the electric motor 20 transfer air to the hose 1 according to the current state.
2) When the pressure sensor 2 detects the peak air pressure in the longitudinal air chambers 25 does no match the preset value of the air pressure detection circuit 18, the air pressure detection circuit 18 transfer a signal to the air pressure pulse regulator 17. The regulated signal is sent to the air pressure compensator 21, and a certain amount of air is transferred to the electric motor 20 via the air pressure compensator 21, so that the air is supplemented to the hose 1.
3) When the coughing sensor 3 detects coughing information from the user, namely, when continuous coughing (≧3 times/10 seconds) occurs, the coughing sensor 3 sends a signal to the power amplifier 19. The amplified signal controls the electric-controlled switch 26 to perform power-off control, so that the electric motor 20 stops transferring air to the pressure vest 8.
When the pressure vest 8 receives the air input by the electric motor 20, the air firstly fills the metal spring coil 10, and partially flows into longitudinal air chambers 25 through the air hole 24. Due to the variation in the air flow transferred by the electric motor 20, the air in the longitudinal air chambers 25 will be discharged from the pressure vest 8 through the air hole 27 to different extent. By changing the air within the longitudinal air chambers 25, an effect of massaging the chest is realized.
The above scheme is a good solution to the conventional problems. However, it is complicated to control the air vibration device 9 comprising the frequency voltage conversion circuit 15, the pulse regulator 16, the air pressure pulse regulator 17, the air pressure detection circuit 18, the power amplifier 19, the electric motor 20, and the air pressure compensator 21. Besides, the air pressure compensator 21 is also realized by an electric motor, so that the whole system is slow in response and consumes significant electricity. During the process of sputum excretion, the patient or an accompanying person is required to act as a guardian. Thus, there is a need for developing a new air vibrating device.
In view of the problems mentioned above, the present invention proposes an electromagnetic powered sputum excretion system. The technical solution of the present invention is realized as follow.

As shown in
In the sputum excretion device, the magnetic force generated by the electromagnet acts on the clappers at both sides to compress the air, thus generating a vibrating airflow. The operating characteristic, i.e., an operation cycle, is as follow: (1) when the electromagnet is energized, a magnetic field is generated, which attracts the clappers to move to the electromagnet from the equilibrium position, thus compressing and extruding the gas in the chamber; and (2) when the electromagnet is de-energized, the magnetic field disappears, so that the clappers return to the equilibrium position due to the loss of the attracting force, thus releasing the space in the chamber and inhaling gas. With this operating characteristic, the air is vibrated, and the chest of a patient is vibrated by the action on the chest of the patient through the pressure vest, thereby the sputum excretion system assists the patient to excrete sputum.
As shown in
