具体实施方式Detailed ways

下面，结合附图对本发明的吸痰管进行详细说明。Below, the sputum suction tube of the present invention will be described in detail with reference to the accompanying drawings.

本发明的吸痰管，其设计为分体式结构，包括管体20和中空的座体30，这样座体可以重复多次利用，管体20可以为一次性耗材。管体20至少在其第一端形成为透明的。管体20的第二端和座体30的第一端气密性地且可插拔地结合在一起。The sputum suction tube of the present invention is designed as a split structure, including atube body 20 and ahollow seat body 30, so that the seat body can be reused many times, and thetube body 20 can be a disposable consumable. Thetube body 20 is formed transparent at least at its first end. The second end of thetube body 20 and the first end of theseat body 30 are combined in an airtight and pluggable manner.

管体20内设置有光纤16，光纤16的第一端设置在管体20的吸痰孔21附近，以观察吸痰孔附近的情况。光纤16的第二端设置在管体20的第二端并形成光纤插头23；管体20的第一端内设置有LED光源15，LED光源15为吸痰管插入患者气道时提供光源；LED光源15的导线延伸至管体20的第二端并形成LED插头。Anoptical fiber 16 is arranged inside thetube body 20, and the first end of theoptical fiber 16 is arranged near thesputum suction hole 21 of thetube body 20, so as to observe the situation near the sputum suction hole. The second end of theoptical fiber 16 is arranged on the second end of thetube body 20 and forms anoptical fiber plug 23; the first end of thetube body 20 is provided with anLED light source 15, and theLED light source 15 provides a light source when the suction tube is inserted into the patient's airway; The wires of theLED light source 15 extend to the second end of thetube body 20 and form an LED plug.

座体30的第二端用于连接负压源，其与现有的吸痰管与负压源连接的一端的结构相同，形成连接接头和负压调节孔。The second end of theseat 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.

座体30的第一端形成光纤插头座33，以结合光纤插头23；座体30的第一端还形成LED插头座31，以结合LED插头；座体30内进一步形成有控制单元10、光纤收发单元16，座体上表面设置有显示单元17；光纤收发单元16与光纤插头座33连接，以接收光纤传输的光信号，并根据接收的光信号变换成电信号并发送给控制单元10，控制单元10根据接收的电信号在显示单元17上显示图像，由此使用者可以获知吸痰孔21附近的情况；控制单元10与LED插头座连31接，以控制LED光源的点亮。控制单元10通过单片机实现。The first end of theseat body 30 forms an opticalfiber plug seat 33 to combine with the fiberoptic plug 23; the first end of theseat body 30 also forms anLED plug seat 31 to combine with the LED plug; theseat body 30 is further formed with acontrol unit 10, an optical fiber Thetransceiver unit 16 is provided with adisplay unit 17 on the upper surface of the base; the opticalfiber transceiver unit 16 is connected to the opticalfiber 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 thecontrol unit 10, Thecontrol unit 10 displays images on thedisplay unit 17 according to the received electrical signal, so that the user can know the situation near thesputum suction hole 21; thecontrol unit 10 is connected with theLED socket 31 to control the lighting of the LED light source. Thecontrol unit 10 is realized by a single-chip microcomputer.

在第二实施例中，在管体20的第一端环绕管体设置有电感器13，至少电感器13的一部分位于吸痰孔21的下游，由此经由吸痰孔21吸入的痰液会穿过电感器13而改变电感器13的电感值。电感器13的两端延伸至管体的第二端并形成电感插头22。In the second embodiment, aninductor 13 is arranged around the first end of thetube body 20, and at least a part of theinductor 13 is located downstream of thesputum suction hole 21, so that the sputum sucked through thesputum suction hole 21 will The inductance value of theinductor 13 is changed across theinductor 13 . Both ends of theinductor 13 extend to the second end of the tube to form aninductor plug 22 .

座体30的第一端形成电感插头座32，以结合电感插头22。座体30中进一步形成有电感测量电路；电感插头座32连接于电感测量电路11，电感测量电路11连接于控制单元10，由此控制单元10可以获知是佛有痰液流经电感器，从侧面反映是否有痰液流过管体20。当吸痰孔中有痰液进入时，电感器的电感值增大。The first end of theseat body 30 forms aninductance plug socket 32 for coupling with theinductance plug 22 . An inductance measurement circuit is further formed in thebase body 30; theinductance plug socket 32 is connected to theinductance measurement circuit 11, and theinductance measurement circuit 11 is connected to thecontrol unit 10, so that thecontrol unit 10 can know that there is sputum flowing through the inductor, from The side reflects whether there is sputum flowing through thetube body 20 . When sputum enters the phlegm suction hole, the inductance value of the inductor increases.

在第三实施例中，座体30的中空部中形成有流量计14，流量计14与控制10单元连接，由此控制单元10可以获知管体20中的流量大小。当吸痰孔吸附在气道粘膜上时，流量计感测的流量值变小。In the third embodiment, aflow meter 14 is formed in the hollow portion of thebase body 30 , and theflow meter 14 is connected to thecontrol unit 10 , so that thecontrol unit 10 can know the flow rate in thepipe body 20 . When the suction hole is adsorbed on the airway mucosa, the flow value sensed by the flow meter becomes smaller.

再将第二实施例与第三实施例相结合的第四实施例中，当吸痰孔21吸入浓痰时，流量计14感测的流量值变小而电感器13的电感值增大。In the fourth embodiment that combines the second embodiment with the third embodiment, when thesuction hole 21 sucks thick sputum, the flow value sensed by theflow meter 14 decreases and the inductance value of theinductor 13 increases.

吸痰孔21可以是位于电感器的两圈导线之间。Thesputum suction hole 21 may be located between two coils of wires of the inductor.

光纤16的第一端朝向管体的外侧，以方便观察与吸痰孔21正对的外部情况。The first end of theoptical fiber 16 faces the outside of the tube body, so as to facilitate the observation of the external situation facing thesputum suction hole 21 .

在仅仅设有光纤的方式，可以通过光纤传导的图像来判断吸痰孔周围的情况，如果看到的是痰液，则表明是痰液被吸入；如果看到的是气道，可能对应两种情况，气道黏膜被吸附或者吸痰孔与气道壁有预定距离且气道壁上没有痰。为了区分这两种情况，可以通过流量计的流量来判断，如果流量很小，则可认为吸附到气道黏膜上。但是，还存在管体被浓痰堵塞的情况，此时从光纤的图像中有可能看不到痰液，而流量计也流量很小，但不能由此就判断是吸附到气道粘膜上，因为浓痰也会使得吸痰管堵塞，此时可通过电感器的电感值变化来判断是否是由于浓痰进入吸痰管而造成流量减小，排除虚警。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.
