如图1所示可报警和自动切换吊瓶的医用点滴器立体示意图，包括主体吊瓶架1，吊瓶2，输液器3，感应元件4，阀门5，支撑管6，输液管7，报警灯22，开关21。As shown in Figure 1, a three-dimensional schematic diagram of a medical dropper that can alarm and automatically switch vials, including a main vial holder 1, vials 2, infusion set 3, sensing element 4, valve 5, support tube 6, infusion tube 7, alarm Light 22, switch 21.
主体吊瓶架1高1.8米，可悬挂吊瓶。支架1.3米高处固定在主体吊瓶架1上有空心的数根支撑管6，此处举例为3根。每根支撑管6远离主体吊瓶架1一端口固定有阀门5。吊瓶2悬挂于支架上，输液器3上端与吊瓶2口相连，下端与输液管7相连。输液器3下端出口带有感应元件4，可以检测输液器3内是否还有液体通过。多根输液管通过各自的阀门之后汇总成一根与针头相连。报警灯22在所有阀门都关闭时会点亮报警，21为启动开关。The main body bottle holder 1 is 1.8 meters high, which can hang a bottle. The bracket 1.3 meters high is fixed on the main body bottle hanger 1 with several hollow support pipes 6, exemplified here as 3. Each support pipe 6 is fixed with a valve 5 at one port away from the main body bottle rack 1 . The hanging bottle 2 is suspended on the support, the upper end of the infusion set 3 is connected with the mouth of the hanging bottle 2 , and the lower end is connected with the infusion tube 7 . The outlet at the lower end of the infusion set 3 is provided with an inductive element 4, which can detect whether there is still liquid passing through the infusion set 3. Multiple infusion tubes pass through their respective valves and are then combined into one and connected to the needle. Alarm lamp 22 can light alarm when all valves are closed, and 21 is a start switch.
如图2所示支架中部其中一个支撑管处的侧面剖视图，输液器3的下方出口处带有感应元件4，感应元件4通过导线10与控制器16相连。控制器16通过导线13与电机11相连，电机11上有可以转动的动杆12。输液器3下端连接输液管7，输液管7在阀门5、塞子9之间。阀门5整体为一端弧面、一端平面的半圆柱体，半圆柱体直径大于输液管7直径，半圆柱体的弧面中间带有凹槽8，供细绳18穿过并且可以让细绳18很容易滑动，塞子9固定于支撑管6的远端管口。细绳18不易断且无伸缩性，细绳18一端固定于塞子9的一侧，绕过阀门5的凹槽8并穿过塞子9的另一侧，通过支撑管6的中空管芯与位于支撑管6近端的电机11上动杆12相连。控制器16通过导线14与报警灯22相连，通过导线15与开关21相连。控制器16，电机12都固定在支架1内侧的固定板17上，电机11固定在每个支撑管6近端管口。启动前，阀门全部处于关闭状态。启动开关21后，主控制器通过导线13对电机11进行控制，电机11控制阀门打开，开始输液。当感应元件4检测到没有液体通过输液器口，即此吊瓶输液结束时，会通过导线10向控制器16发出信号。控制器16接收到信号之后再向电机11发送信号，电机控11制阀门关闭，即阀门5平面端与塞子9压合，使位于阀门5平面端与塞子9中间的输液管7压闭，然后向控制器16发送反馈信号，控制器16再向其他支撑管6近端口的电机发送信号使其控制另外的阀门，开始第二瓶输液。当所有吊瓶都输完，即所有阀门都关闭之后，控制器16通过导线14向报警灯22发送信号，点亮报警灯22。As shown in FIG. 2 , the side sectional view of one of the support tubes in the middle of the bracket, the lower outlet of the infusion set 3 has a sensing element 4 , and the sensing element 4 is connected to the controller 16 through a wire 10 . The controller 16 is connected to the motor 11 through the wire 13, and the moving rod 12 that can rotate is arranged on the motor 11. The lower end of the infusion set 3 is connected with the infusion tube 7, and the infusion tube 7 is between the valve 5 and the stopper 9. The valve 5 is a semi-cylindrical body with an arc surface at one end and a plane at the other end. The diameter of the semi-cylindrical body is larger than the diameter of the infusion tube 7. There is a groove 8 in the middle of the arc surface of the semi-cylindrical body for the string 18 to pass through and allow the string 18 to pass through. It is easy to slide, and the stopper 9 is fixed on the distal nozzle of the support tube 6 . The string 18 is not easy to break and has no flexibility. One end of the string 18 is fixed on one side of the plug 9, bypasses the groove 8 of the valve 5 and passes through the other side of the plug 9, and passes through the hollow tube core of the support pipe 6 and the The motor 11 located at the proximal end of the support tube 6 is connected to the upper moving rod 12 . The controller 16 is connected to the warning light 22 through the wire 14 and connected to the switch 21 through the wire 15 . The controller 16 and the motor 12 are all fixed on the fixed plate 17 inside the bracket 1 , and the motor 11 is fixed on the proximal nozzle of each support tube 6 . Before starting, the valves are all closed. After starting the switch 21, the main controller controls the motor 11 through the wire 13, and the motor 11 controls the opening of the valve to start infusion. When the sensing element 4 detects that there is no liquid passing through the mouth of the infusion set, that is, when the infusion via the suspension bottle is finished, it will send a signal to the controller 16 through the wire 10 . The controller 16 sends a signal to the motor 11 after receiving the signal, and the motor controls the valve to close, that is, the flat end of the valve 5 is pressed against the plug 9, so that the infusion tube 7 located between the flat end of the valve 5 and the plug 9 is pressed closed, and then Send a feedback signal to the controller 16, and the controller 16 sends a signal to other motors near the end of the support tube 6 to control another valve to start the second bottle of infusion. When all hanging bottles have been lost, that is, after all valves are closed, the controller 16 sends a signal to the warning lamp 22 through the wire 14, and lights the warning lamp 22.
如图3所示阀门闭合时支撑管处俯视剖面图，此时为阀门闭合状态，输液管无法正常流通液体。细绳18一端固定点20固定在塞子9上，沿着凹槽8绕过阀门5，通过塞子9上的小孔19，再通过支撑管6，与电机11的动杆12相连。当电机11接收到控制器16发出的要求打开阀门的信号时，动杆12将逆时针转动，此时固定点20到动杆12之间的细绳18将会变长，此时阀门5和塞子9将会慢慢分开。As shown in Figure 3, when the valve is closed, the cross section of the support tube is viewed from above. At this time, the valve is in the closed state, and the infusion tube cannot circulate liquid normally. One end fixed point 20 of string 18 is fixed on the plug 9, walks around valve 5 along groove 8, passes through the aperture 19 on the plug 9, passes through support tube 6 again, links to each other with the moving rod 12 of motor 11. When the motor 11 received the signal from the controller 16 to open the valve, the moving rod 12 would rotate counterclockwise, and now the string 18 between the fixed point 20 and the moving rod 12 would become longer. The plug 9 will slowly come apart.
如图4所示阀门打开时支撑管处俯视剖面图，此时为阀门打开状态，输液管7内可以正常流通液体。当感应元件4检测到液体输完并发出信号之后，控制器16会对电机11发出闭合阀门的信号，电机11接收到信号之后会控制动杆12进行顺时针转动，此时细绳18慢慢卷入电机，阀门5和塞子9慢慢靠近直至紧贴，此时呈现图3的状态，输液管7无法继续流通液体。As shown in FIG. 4 , when the valve is opened, the top view of the support pipe is a sectional view. At this time, the valve is in an open state, and the liquid can flow normally in the infusion tube 7 . When the sensing element 4 detects that the liquid has been delivered and sends a signal, the controller 16 will send a signal to the motor 11 to close the valve. After receiving the signal, the motor 11 will control the brake lever 12 to rotate clockwise. At this time, the string 18 slowly Involved in the motor, the valve 5 and the stopper 9 slowly approach until they are close to each other. At this time, the state shown in Figure 3 is shown, and the infusion tube 7 cannot continue to circulate liquid.
如图5所示控制元件连接图，开关闭合的信号送入控制器，控制器开始工作，每个吊瓶2下装一个感应元件，对应的每根支撑管6近端口装一个电机，每组感应元件送入控制器，控制器检测感应元件信号后，输出控制信号到对应电机，开始控制各组吊瓶顺序点滴工作，当全部感应元件都为无液状态，控制器发信号到报警灯，报警灯亮。As shown in the connection diagram of the control elements in Figure 5, the closed signal of the switch is sent to the controller, and the controller starts to work. An induction element is installed under each hanging bottle 2, and a motor is installed at the near port of each supporting tube 6 correspondingly. The sensing element is sent to the controller. After the controller detects the signal of the sensing element, it outputs the control signal to the corresponding motor, and starts to control the sequential drip work of each group of hanging bottles. When all the sensing elements are in an anhydrous state, the controller sends a signal to the alarm light. The warning light comes on.
此处只举例一个阀门的操作形式，实际中可设计成多个阀门。当启动之后开始输液至所有阀门都为闭合状态时，即输液全部完成，主控制器会对报警灯发送信号，报警灯将会点亮。Here, only one valve operation form is exemplified, and multiple valves can be designed in practice. When starting the infusion until all valves are closed, that is, the infusion is all completed, the main controller will send a signal to the alarm light, and the alarm light will light up.
另外，本发明并不局限于上述3个输液装置，实际操作中可设计成可悬挂多个吊瓶支架。In addition, the present invention is not limited to the above three infusion devices, and it can be designed to hang multiple hanging bottle holders in actual operation.
