The optional embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0020] See also Figure 1 A double-connector infusion set comprises two input ends 1, an output end 3 and a Y-type infusion tube 2, wherein the input end 1 comprises a piercer 4, a flow display 5, a first flow sensor 6, an electromagnetic valve 7 and a transmission tube 8, the piercer 4 is connected to the transmission tube 8, the transmission tube 8 is connected to the input interface of the Y-type infusion tube 2, the output interface of the Y-type infusion tube 2 is connected to the output end 3, the flow display 5, the first flow sensor 6 and the electromagnetic valve 7 are all arranged on the transmission tube 8, and the first flow sensor 6 is connected to the flow display 5 signal, and a control element 9 is provided on the Y-type infusion tube 2, and the control element 9 is connected to the first flow sensor 6 and the electromagnetic valve 7 signal.

[0021] The utility model discloses a double-joint infusion set, wherein two input ends 1 are respectively connected to different infusion bottles, and the medicine flows into the transmission tube 8 from the infusion bottle. In this initial stage, the control element 9 drives the electromagnetic valve 7 to close so that the transmission tubes 8 of the two input ends 1 are clamped and cannot be infused. After manual selection by medical staff, the electromagnetic valve 7 corresponding to the input end 1 is opened, and the corresponding transmission tube 8 is conducted, and the medicine flows into the output end 3 from an input interface of the Y-shaped infusion tube 2 and is finally injected into the human body. In this process, the flow rate of the medicine in the transmission tube 8 is monitored by the first flow sensor 6 on the corresponding transmission tube 8 and displayed by the flow display 5. When the infusion bottle corresponding to one of the input ends 1 ends the infusion, the control element 9 automatically turns off the electromagnetic valve 7 on the old transmission tube 8 and starts the electromagnetic valve 7 on the new transmission tube 8. In summary, the utility model can realize automatic switching between two different medicines and has the function of prompting the infusion process. The caregiver does not need to pay attention to the infusion process all the time, which greatly reduces the burden on the caregiver and medical staff.

[0022] Specifically, the control element 9 includes a controller and a first start button 10 and a second start button 11. The first start button 10 and the second start button 11 are both connected to the controller signal. The controller is connected to the first flow sensor 6 and the solenoid valve 7 signal. Exemplarily, the first start button 10 and the second start button 11 correspond to two different solenoid valves 7 respectively. When the two input ends 1 are connected to different infusion bottles respectively, the medical staff manually presses the first start button 10 or the second start button 11, and the corresponding solenoid valve 7 is opened, and the transmission tube 8 where the corresponding solenoid valve 7 is located is turned on, and the drug solution flows through the corresponding transmission tube 8 into an input interface of the Y-shaped infusion tube 2 and flows into the output end 3 and is finally injected into the human body.

[0023] Specifically, the output interface of the Y-type infusion tube 2 is connected to the output end 3 through a drip bucket 12. The connection part between the drip bucket 12 and the output end 3 is provided with a second flow sensor 13. The second flow sensor 13 is connected to the controller signal. Exemplarily, the second flow sensor 13 is used to sense the medicine flowing out of the Y-type infusion tube 2. When the solenoid valve 7 is in the state of one being started and the other being closed, and the second flow sensor 13 cannot detect the presence of a flow signal at the drip bucket 12, it means that the medicine in one of the medicine bottles has been infused. At this time, the controller shuts down the originally started solenoid valve 7 and starts the originally closed solenoid valve 7, thereby realizing automatic switching of the drug infusion process.

[0024] Specifically, the output end 3 includes an infusion hose 14 and a needle 15, the drip bucket 12 is connected to one end of the infusion hose 14, and the other end of the infusion hose 14 is connected to the needle 15, and the infusion hose 14 and the needle 15 are used to inject the medicine into the human body.

[0025] Specifically, the controller is also connected to the alarm light and the alarm speaker respectively. When the first flow sensor 6 and the second flow sensor 13 cannot sense the flow signal, the controller will drive the alarm light and the alarm speaker to work, prompting medical staff to change the dressing or remove the needle.

[0026] Specifically, a liquid medicine filter 16 is provided on the infusion hose 14 .

[0027] The working principle is as follows: when in use, two piercers 4 are respectively inserted into the infusion bottles, and the liquid flows from the infusion bottles into the transmission tube 8. In this initial stage, the control element 9 drives the electromagnetic valve 7 to close so that the transmission tubes 8 at the two input ends 1 are clamped and cannot be infused. The medical staff manually presses the first start button 10 or the second start button 11, and the corresponding electromagnetic valve 7 is opened, and the transmission tube 8 where the corresponding electromagnetic valve 7 is located is connected. The medicine flows through the corresponding transmission tube 8 into an input interface of the Y-type infusion tube 2 and flows into the output end 3. In this process, the flow rate of the medicine in the transmission tube 8 will be monitored by the first flow sensor 6 on the corresponding transmission tube 8 and displayed by the flow display 5. At the same time, the medicine flowing out of the Y-type infusion tube 2 is sensed by the second flow sensor 13. When the second flow sensor 13 detects no flow signal at the drip bucket 12, it means that the medicine in one of the medicine bottles has been infused. At this time, the controller turns off the originally started electromagnetic valve 7 and starts the originally closed electromagnetic valve 7, thereby realizing automatic switching of the drug infusion process.
