[0001] The utility model relates to a monitoring device, in particular to a liquid medicine dosage monitoring device. Background Art

[0002] In daily life, patients need intravenous infusion through an infusion set due to medical treatment needs. Some liquid medicines have dosage requirements, but the amount of the whole bottle of liquid medicine exceeds the single-use dosage. For example, bottled liquid medicines such as mannitol and sodium bicarbonate are mostly in a group of 250ml, and in many cases the single-use dosage is half of 250ml, that is, 125ml. Of course, there are other cases where the single-use dosage is less than 250ml.

[0003] In order to avoid injecting more liquid medicine into the patient's body than the amount prescribed by the doctor, medical staff usually use a syringe to extract the excess liquid medicine, and then inject the remaining amount of liquid medicine into the patient. This method has certain disadvantages. Due to the particularity of the drug, when the excess liquid medicine encounters air or temperature difference when being extracted, the properties of the drug are affected or even crystallized again. It will also increase the workload of medical staff to a certain extent, and they need to prepare additional containers to hold the excess liquid medicine, which poses certain safety risks and inconveniences.

[0004] Usually, an infusion set is provided with a Murphy's dropper, and the Murphy's dropper of a conventional infusion set generally defaults to 15 drops for 1 ml.

[0005] Therefore, based on the existing technology, the utility model provides a monitoring device that can monitor the dosage of liquid medicine, which does not require medical staff to draw out excess liquid medicine, thereby improving work efficiency, and can also clamp the infusion tube when the dosage of liquid medicine reaches a set value.

[0008] A liquid medicine dosage monitoring device comprises a first clamping plate, a second clamping plate, an infrared transmitter, an infrared receiver, an input button, a central processing unit, a power module and an electric push rod; the first clamping plate and the second clamping plate are detachably assembled together, the mutually attached plate surfaces of the first clamping plate and the second clamping plate are both provided with a Murphy-type dropper groove and an infusion extension tube groove, and the upper and lower ends of the Murphy-type dropper groove are both connected to the infusion extension tube groove; the infrared transmitter is arranged on one side of the Murphy-type dropper groove of the second clamping plate, and is used to transmit infrared rays; the infrared receiver is arranged on the other side of the Murphy-type dropper groove of the second clamping plate, and is used to receive The infrared ray emitted by the infrared transmitter is electrically connected to the central processing unit; the input button, the central processing unit, the power module and the electric push rod are arranged on the other side of the second clamping plate relative to the Murphy-type dropper groove, the central processing unit is electrically connected to the input button, and the power module is used to provide a working voltage; the electric push rod is arranged at the upper end of the second clamping plate, and is electrically connected to the central processing unit; the plate surface of the second clamping plate is provided with a through hole for the telescopic end of the electric push rod to pass through, and the through hole is connected to the infusion extension tube groove at the upper end of the Murphy-type dropper groove, and after the electric push rod is extended, the end of its telescopic end can squeeze the infusion extension tube in the infusion extension tube groove.

[0009] The beneficial effects of the utility model are:

[0010] The utility model provides a device for monitoring the amount of liquid medicine. Before infusion, the Murphy's dropper of the infusion device and the infusion extension tubes at the upper and lower ends of the Murphy's dropper are placed in the Murphy's dropper tube groove and the infusion extension tube tube groove respectively. Then, the first clamp plate and the second clamp plate are assembled together, and the amount of liquid medicine is input to the central processing unit through the input key. The central processing unit converts the amount of liquid medicine into the total number of drops. During the infusion process, when no liquid is dripped, the infrared rays emitted by the infrared transmitter will be received by the infrared receiver. When liquid is dripped, the infrared receiver cannot receive the infrared rays or can only receive weak infrared rays. At this time, the infrared rays The receiver sends a feedback signal that it cannot receive infrared rays or receives weak infrared rays to the central processing unit. The central processing unit processes the signal according to its built-in program and accumulates the value of liquid dripping, and repeats this process to achieve the purpose of monitoring the liquid usage. When the total value of liquid dripping recorded by the central processing unit is equal to the input value, the central processing unit controls the electric push rod to work, and the telescopic end of the electric push rod extends and squeezes the infusion extension tube to achieve the purpose of clamping the infusion tube. The medicine will not continue to drip. The monitoring device does not require medical staff to extract excess medicine through a syringe, thereby improving the work efficiency of medical staff.

The side walls of the first splint 1 and the second splint 2 are both provided with anti-slip grooves 50, which facilitates the separation of the first splint 1 and the second splint 2.

[0021] The infrared transmitter 3 is arranged on one side of the Murphy's dropper groove 8 of the second clamping plate 2, and is used to transmit infrared rays. The infrared receiver 10 is arranged on the other side of the Murphy's dropper groove 8 of the second clamping plate 2, and is used to receive the infrared rays emitted by the infrared transmitter 3, and is electrically connected to the central processing unit 5. The infrared transmitter 3 of this embodiment adopts an IR333_H0 infrared transmitting tube, which is represented by D10 in the circuit. The infrared receiver 10 adopts a HS0038B chip, and the output end (DATE pin) of the infrared receiver 10 is electrically connected to the input end of the central processing unit 5, and it sends a feedback signal to the central processing unit 5 through the DATE pin, and the central processing unit 5 decodes the feedback signal according to the program set inside it. When no liquid drips between the infrared transmitter 3 and the infrared receiver 10 through the Murphy's dropper, the infrared receiver 10 can receive the infrared rays emitted by the infrared transmitter 3. When liquid drips between the infrared transmitter 3 and the infrared receiver 10 through the Murphy's dropper, the infrared rays emitted by the infrared transmitter 3 are refracted and reflected by the liquid, and the infrared receiver 10 cannot receive the infrared rays, or receives extremely weak infrared rays (which can be approximated as no infrared rays being received). The infrared receiver 10 sends a feedback signal to the central processor 5 indicating that it cannot receive infrared rays or receives weak infrared rays.

[0022] The input button 4, the central processing unit 5, the power module 6 and the electric push rod 7 are arranged on the other side of the second clamping plate 2 relative to the Murphy-type dropper pipe groove 8. The central processing unit 5 is electrically connected to the input button 4, and the power module 6 is used to provide a working voltage. A shell 100 is arranged on the board surface of the second clamping plate 2 where the central processing unit 5 is arranged. The central processing unit 5 and the power module 6 are arranged in the shell 100. The central processing unit 5 of this embodiment adopts a single-chip microcomputer module with an STM32 series single-chip microcomputer as the core. In the circuit, some unused pins are omitted. The input button 4 is arranged on the surface of the shell 100, and there are multiple input buttons 4, wherein the input button 4 can realize the functions of inputting a value (liquid dosage) to the central processing unit 5, determining the input value, and clearing the value. The input button 4 is represented by "K1, K2, ... Kn" in the circuit.

[0023] The electric push rod 7 is arranged at the upper end of the second clamping plate 2, and is electrically connected to the central processing unit 5. The central processing unit 5 is used to control the extension and retraction of the electric push rod 7. A mounting plate 20 is arranged above the housing 100, and the electric push rod 7 is mounted on the mounting plate 20. The plate surface of the second clamping plate 2 is provided with a through hole 21 for the telescopic end of the electric push rod 7 to pass through. The through hole 21 is connected to the infusion extension tube groove 9 at the upper end of the Murphy-type dropper groove 8. After the electric push rod 7 is extended, the end of its telescopic end can squeeze the infusion extension tube in the infusion extension tube groove 9, thereby clamping the infusion extension tube. Since the electric push rod 7 is generally driven by a motor, the electric push rod 7 is represented by "M" in the circuit, and the RESKEY button in the circuit is used to control the electric push rod 7 to reset.

[0024] The housing 100 is also provided with a speaker 30 and a display screen 40, both of which are electrically connected to the central processor 5. The speaker 30 is used to sound an alarm, which is represented by "SPEAK" in the circuit, and the display screen 40 is used to display information, and its model is an LCD1602 display screen.

[0025] A clamp 12 for clamping the first clamp 1 on the infusion pole is provided on the surface of the first clamp 1, and the clamp 12 is provided on the surface of the first clamp 1 opposite to the Murphy-type dropper groove 8. The clamp 12 can improve the stability of the first clamp 1 and the second clamp 2, so that they are not easy to fall when in use. The clamp 12 of this embodiment includes a connecting rod, a fastening ring and a fastening bolt. The fastening ring is elastic, and one side of the fastening ring is provided with an opening, which is used to elastically clamp the infusion pole. The fastening bolt is provided at the opening, which is used to adjust the size of the opening and make the inner wall of the fastening ring tighten on the side wall of the infusion pole, so as to fix the fastening ring on the infusion pole. The connecting rod is provided on the other side of the fastening ring provided with the opening, and is connected between the surface of the first clamp 1 and the outer wall of the fastening ring.

[0026] The use principle of the utility model is: before infusion, the Murphy's dropper of the infusion device and the infusion extension tubes at the upper and lower ends of the Murphy's dropper are respectively placed in the Murphy's dropper tube groove 8 and the infusion extension tube tube groove 9, then the first clamping plate 1 and the second clamping plate 2 are assembled together, and then the clamp 12 is clamped on the infusion pole. The installation order can be appropriately changed according to the situation.

[0027] After installation, the default model of the Murphy dropper is 15 drops for 1 ml, so the amount of liquid medicine is input to the central processor 5 through the input button 4, and then the central processor 5 converts it into the number of drops. For example: if the input amount of liquid medicine is 100 ml, the central processor 5 converts the amount of liquid medicine to 1500 drops; if the input amount of liquid medicine is 200 ml, the central processor 5 converts the amount of liquid medicine to 3000 drops. During the infusion process, when no liquid is dripped, the infrared light emitted by the infrared transmitter 3 will be received by the infrared receiver 10. When liquid is dripped, the infrared receiver 10 cannot receive the infrared light or can only receive weak infrared light. At this time, the infrared receiver 10 cannot receive the infrared light or can only receive weak infrared light. The feedback signal is sent to the central processor 5. The central processor 5 processes the signal according to its built-in program and accumulates the value of liquid dripping. In the initial state, the value of the central processor 5 is 0, and the value is increased by one for each drop of liquid dripped, and this is repeated, thereby realizing the infusion of liquid. For the purpose of monitoring the amount of liquid, when the total value of liquid dripping recorded by the central processor 5 is equal to the input value, the central processor 5 controls the electric push rod 7 to work, and the telescopic end of the electric push rod 7 extends and squeezes the infusion extension tube to achieve the purpose of clamping the infusion tube. The medicine will not continue to drip, and the speaker 30 is controlled to sound an alarm to remind patients, family members and medical staff that the medicine is about to be delivered. Therefore, the monitoring device does not require medical staff to extract excess medicine through a syringe, thereby improving the work efficiency of medical staff. After use, press the RESKEY button to reset the electric push rod 7, and then remove the device.
