Detailed ways

Below, the sputum suction tube of the present invention will be described in detail with reference to the accompanying drawings.

The sputum suction tube of the present invention is designed as a split structure, including a tube body 20 and a hollow seat body 30, so that the seat body can be reused many times, and the tube body 20 can be a disposable consumable. The tube body 20 is formed transparent at least at its first end. The second end of the tube body 20 and the first end of the seat body 30 are combined in an airtight and pluggable manner.

An optical fiber 16 is arranged inside the tube body 20, and the first end of the optical fiber 16 is arranged near the sputum suction hole 21 of the tube body 20, so as to observe the situation near the sputum suction hole. The second end of the optical fiber 16 is arranged on the second end of the tube body 20 and forms an optical fiber plug 23; the first end of the tube body 20 is provided with an LED light source 15, and the LED light source 15 provides a light source when the suction tube is inserted into the patient's airway; The wires of the LED light source 15 extend to the second end of the tube body 20 and form an LED plug.

The second end of the seat body 30 is used to connect to a negative pressure source, which has the same structure as the end of the existing sputum suction tube connected to the negative pressure source, forming a connection joint and a negative pressure adjustment hole.

The first end of the seat body 30 forms an optical fiber plug seat 33 to combine with the fiber optic plug 23; the first end of the seat body 30 also forms an LED plug seat 31 to combine with the LED plug; the seat body 30 is further formed with a control unit 10, an optical fiber The transceiver unit 16 is provided with a display unit 17 on the upper surface of the base; the optical fiber transceiver unit 16 is connected to the optical fiber plug socket 33 to receive the optical signal transmitted by the optical fiber, and converts the received optical signal into an electrical signal and sends it to the control unit 10, The control unit 10 displays images on the display unit 17 according to the received electrical signal, so that the user can know the situation near the sputum suction hole 21; the control unit 10 is connected with the LED socket 31 to control the lighting of the LED light source. The control unit 10 is realized by a single-chip microcomputer.

In the second embodiment, an inductor 13 is arranged around the first end of the tube body 20, and at least a part of the inductor 13 is located downstream of the sputum suction hole 21, so that the sputum sucked through the sputum suction hole 21 will The inductance value of the inductor 13 is changed across the inductor 13 . Both ends of the inductor 13 extend to the second end of the tube to form an inductor plug 22 .

The first end of the seat body 30 forms an inductance plug socket 32 for coupling with the inductance plug 22 . An inductance measurement circuit is further formed in the base body 30; the inductance plug socket 32 is connected to the inductance measurement circuit 11, and the inductance measurement circuit 11 is connected to the control unit 10, so that the control unit 10 can know that there is sputum flowing through the inductor, from The side reflects whether there is sputum flowing through the tube body 20 . When sputum enters the phlegm suction hole, the inductance value of the inductor increases.

In the third embodiment, a flow meter 14 is formed in the hollow portion of the base body 30 , and the flow meter 14 is connected to the control unit 10 , so that the control unit 10 can know the flow rate in the pipe body 20 . When the suction hole is adsorbed on the airway mucosa, the flow value sensed by the flow meter becomes smaller.

In the fourth embodiment that combines the second embodiment with the third embodiment, when the suction hole 21 sucks thick sputum, the flow value sensed by the flow meter 14 decreases and the inductance value of the inductor 13 increases.

The sputum suction hole 21 may be located between two coils of wires of the inductor.

The first end of the optical fiber 16 faces the outside of the tube body, so as to facilitate the observation of the external situation facing the sputum suction hole 21 .

In the way with only optical fiber, the situation around the suction hole can be judged through the image transmitted by the optical fiber. If you see sputum, it means that the sputum is inhaled; if you see the airway, it may correspond to two In this case, the airway mucosa is absorbed or there is a predetermined distance between the suction hole and the airway wall and there is no sputum on the airway wall. In order to distinguish these two situations, it can be judged by the flow rate of the flow meter. If the flow rate is small, it can be considered to be adsorbed on the airway mucosa. However, there are still cases where the tube body is blocked by thick sputum. At this time, the sputum may not be seen in the image of the optical fiber, and the flow rate of the flowmeter is also very small, but it cannot be judged that it is adsorbed on the airway mucosa. Because thick sputum will also block the suction tube, at this time, the change of inductance value of the inductor can be used to judge whether the flow rate is reduced due to thick sputum entering the suction tube, so as to eliminate false alarms.
