The present invention relates to an intelligent exhaled sputum-suction and inhaled oxygen-supply device.
Please refer to
The outer tube 111 is inserted into the tracheostomy tube of the patient to supply oxygen to the patient through the oxygen-supply tube 112, and then the suction tube 113 is inserted into the tracheostomy tube through the outer tube 111 for sputum suction.
However, during sputum suction, the operator has to observe the blood oxygen concentration of the patient. When the blood oxygen concentration of the patient is decreased, the suction tube 113 has to be removed from the tracheostomy tube of the patient immediately so that the oxygen-supply tube 112 can supply oxygen to the patient. Therefore, the operator has to cautiously observe the blood oxygen concentration and move the suction tube 113 at the same time, which is inconvenient to operate and requires an experienced operator.
The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
The main object of the present invention is to provide an intelligent exhaled sputum-suction and inhaled oxygen-supply device to overcome the above-mentioned disadvantages.
To achieve the above and other objects, the present invention provides an intelligent exhaled sputum-suction and inhaled oxygen-supply device, configured to be applied to a respiratory tract of a patient, including: a sputum-suction and oxygen-supply tube unit, a gas-regulating unit and a control unit.
The sputum-suction and oxygen-supply tube unit includes a major oxygen-supply tube and a major sputum-suction tube configured to be disposed through the respiratory tract. The gas-regulating unit includes an oxygen-supply module, a sputum-suction module, a minor oxygen-supply tube communicating the oxygen-supply module with the major oxygen-supply tube, a minor sputum-suction tube communicating the sputum-suction module with the major sputum-suction tube, and a respiration sensor configured to sense a breathing state of the patient. The control unit is electrically connected with the sputum-suction module and the respiration sensor, and the control unit controls the sputum-suction module to draw gas from the minor sputum-suction tube when the respiration sensor senses that the patient is in an exhalation state.
The advantage of the present invention is that: with the configurations of the major oxygen-supply tube, the major sputum-suction tube, the oxygen-supply module, the sputum-suction module and the respiration sensor, the intelligent exhaled sputum-suction and inhaled oxygen-supply device can intelligently supply oxygen and suck sputum according to the breathing state of the patient, so that the patient can inhale oxygen when breathing in and be sucked sputum when breathing out, which simplifies the operating processes.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

The whole sputum suction process of the present invention is carried out by an intelligent procedure, which largely reduces the operating processes and the technical requirements of the operator.
In other embodiments, the intelligent exhaled sputum-suction and inhaled oxygen-supply device may be configured without the driving unit 5, the front adapter unit 6 and the rear adapter unit 7, the major oxygen-supply tube 21 are separated from the major sputum-suction tube 22, and the major oxygen-supply tube 21 and the major sputum-suction tube 22 are respectively connected with the minor oxygen-supply tube 34 and the minor sputum-suction tube 35. In operation, the major oxygen-supply tube 21 and the major sputum-suction tube 22 may be disposed within the patient' mouth or nostrils, and the oxygen-supply module 31 supplies oxygen continuously. The control unit 8 intelligently determines the breathing state of the patient, and the position of the major sputum-suction tube 22 is adjustable manually. Since the operator does not need to observe the blood oxygen concentration of the patient, the effect of reducing the technical requirements of the operator is also achieved.
