[0040] like Figure 2 As shown, an embodiment of the utility model provides an infusion stand, which includes a base 13, a support tube 14 vertically arranged on the base 13, a telescopic rod 9 inserted on the top of the support tube 14, and a hanging ear 15 installed on the top of the telescopic rod 9. Figure 1 Unlike the existing infusion stand shown in the figure, the infusion stand provided in the present application is also provided with an infusion status monitoring device 100 on the telescopic rod 9, and the infusion status monitoring device 100 is used to monitor the infusion flow rate and the remaining amount of liquid medicine in the infusion bag 300 in real time, which can make the infusion scene more intelligent.

[0041] Specifically, Figure 4 , Figure 5 and Figure 6 As shown, the infusion state monitoring device 100 includes a package and an infusion state monitoring system. The package includes a main body 7, a connecting portion 10 for mounting the main body 7 on the telescopic rod 9 of the infusion stand, and a fixing portion for vertically fixing the infusion drop bucket 200, and the connecting portion 10, the fixing portion and the main body 7 are integrally arranged. The connecting portion 10, the fixing portion and the main body 7 can be integrally formed by injection molding.

[0042] To facilitate installation and disassembly, the connecting portion 10 is a card slot, which is directly connected to the telescopic rod 9 through the card slot. In order to prevent the card slot from sliding randomly after being connected to the telescopic rod 9, a silicone layer is provided on the inner wall of the card slot, and the silicone layer increases the friction coefficient between the card slot and the outer wall of the telescopic rod 9, thereby increasing the resistance when the card slot and the telescopic rod 9 slide relative to each other, so that the main body 7 can be stably installed on the telescopic rod 9 through the card slot.

[0043] The fixing portion includes two buckles 12 disposed opposite to each other up and down on one side of the main body 7. After the pipes at both ends of the infusion drip bucket 200 are respectively clamped in the corresponding buckles 12, the infusion drip bucket 200 is fixed longitudinally.

[0044] In this embodiment, Figure 2 As shown, a battery 16 for powering the infusion status monitoring device is disposed on the base 13. The battery 16 can be a rechargeable lithium battery.

[0045] In this embodiment, Figure 7 As shown, the infusion status monitoring system includes a droplet sensing module, a control module, a reminder module and a wireless module, and the droplet sensing module, the reminder module and the wireless module are all electrically connected to the control module. Among them, the droplet sensing module is used to send a trigger signal to the control module every time a droplet falls in the infusion drop bucket 200; the control module is used to count the trigger signals, and calculate the infusion flow rate and the amount of medicine remaining in the infusion bag 300 according to the count number and frequency of the trigger signals. If the infusion flow rate is less than the preset first threshold or greater than the preset second threshold, or the remaining amount of medicine is less than the preset third threshold, the reminder module is controlled to send a reminder message. The wireless module is used to send the count number and frequency of the trigger signal to the server in real time. The monitoring working principle diagram of the infusion status monitoring device 100 is shown in the figure. Figure 3 shown.

[0046] The droplet sensing module is disposed between the two buckles 12. Figure 5 , Figure 6 and Figure 8 As shown, the droplet sensing module includes a relatively arranged photosensor 1 and an infrared light emitting diode 2 and a voltage comparator. The voltage comparator is used to output a trigger voltage signal to the control module according to the voltage change at both ends of the photosensor 1. The model of the voltage comparator is LM393M, and the model of the photosensor 1 is QSE112.

[0047] Specifically, the photosensor 1 and the infrared light emitting diode 2 are respectively arranged on both sides of the infusion drop bucket 200. When a drop of liquid drips from the top of the infusion drop bucket 200, when the drop of liquid drips between the photosensor 1 and the infrared light emitting diode 2, it will affect the light intensity received by the photosensor 1 from the infrared light emitting diode 2, the resistance of the photosensor 1 increases, and the voltage across the photosensor 1 increases, so that the input voltage of pin 3 of the voltage comparator is higher than the reference voltage of pin 2; when the drop of liquid falls through the photosensor 1 and the infrared light emitting diode 2, the light received by the photosensor 1 from the infrared light emitting diode 2 is enhanced, the resistance of the photosensor 1 decreases, and the voltage across the photosensor 1 decreases, so that the input voltage of pin 3 of the voltage comparator is lower than the reference voltage of pin 2.

[0048] When the input voltage is less than or equal to the reference value, the output voltage of pin 1 of the voltage comparator remains unchanged; when the input voltage is greater than the reference value, the output voltage of pin 1 of the voltage comparator changes, thereby completing a triggering of the control module.

[0049] The volume of each drop of liquid in the infusion drop bucket 200 can be measured in advance and set in the control module. The control module can calculate the infusion flow rate and the amount of liquid medicine remaining in the infusion bag 300 by counting the frequency of the trigger signal sent by the droplet sensing module and counting the trigger signals, wherein the amount of liquid medicine output is equal to the product of the droplet count and the volume of each droplet. If the infusion flow rate is too fast, too slow, or the dripping stops, the control module controls the reminder module to send a reminder message in time to give a timely alarm.

[0050] During infusion, the initial amount of liquid medicine in the infusion bag 300 is set in the control module, and then the amount of liquid medicine that has been output is subtracted to calculate the remaining amount of liquid medicine in the infusion bag 300. When the amount of liquid medicine remaining in the infusion bag 300 is less than the preset third threshold value, the control module controls the reminder module to promptly send a reminder message to prompt that the infusion is completed.

[0051] In this embodiment, the control module can adopt a single-chip microcomputer, the reminder module can adopt a speaker 3, and the wireless module can adopt a 4G module, a 5G module, a WiFi module or a cat.1 wireless communication module. The cat.1 wireless communication module has the advantages of high-speed transmission, low power consumption, low cost and high reliability.

[0052] After the wireless module sends the count number and frequency of the trigger signal to the server, it is stored in the database. The server records the infusion process data throughout the process, generates statistical reports according to management requirements, and sends them to the terminal held by the corresponding medical staff or the management terminal of the hospital. In addition, when the server determines that the infusion flow is too fast, too slow, or dripping stops based on the count number and frequency of the trigger signal, or when the remaining amount of liquid medicine in the patient's infusion bag 300 is less than the preset third threshold, the server will send a corresponding prompt message to the terminal held by the medical staff or the management terminal of the hospital, so as to promptly remind the medical staff to take medical measures to avoid infusion medical accidents.

[0053] In this embodiment, Figure 7 As shown, the infusion status monitoring system may further include a key module 4, which is electrically connected to the control module. The key module 4 has a plurality of keys with different functions, and the key module 4 is mounted on the main body 7 of the package. When the patient needs to contact the nurse, after pressing the corresponding key, the control module sends a prompt message to the terminal held by the nurse through the wireless module. When the nurse receives the prompt message through the terminal, the corresponding patient can be found as soon as possible.

[0054] Further, if Figure 7As shown, the infusion status monitoring system further includes an illumination module 5, which is electrically connected to the control module. The illumination module 5 is an LED lamp. When the corresponding switch button on the key module 4 is pressed at night, the control module controls the LED lamp to turn on and emit light through the switch tube, so that it is convenient for patients or medical staff to check the remaining amount of liquid medicine in the infusion bag 300, or to check the infusion status.

[0055] It is understandable that the lighting module 5 can also serve as a reminder. When the infusion flow rate is too fast, too slow, or dripping, or when the amount of liquid medicine remaining in the infusion bag 300 is less than the preset third threshold, the controller module can also control the lighting module 5 to light up or flash to remind the patient or medical staff.

[0056] In this embodiment, the control module and the wireless module are integrated on the main board and packaged in the main body 7 of the package. The button module 4, the lighting module 5 and the reminder module are all embedded on the side wall of the main body 7 of the package.

[0057] In summary, the infusion stand provided in the present application has an infusion status monitoring device, which calculates the infusion volume and the amount of liquid medicine remaining in the infusion bag 300 by counting the droplets in the infusion dropper 200, and calculates the infusion flow rate according to the droplet dripping frequency. When the infusion flow rate is greater than the preset first threshold, or the remaining liquid medicine amount is less than the preset second threshold, a reminder message is sent through the reminder module, thereby reminding medical staff and patients to pay attention and adjust the flow rate or remove the needle in time.

[0058] In addition, the infusion status monitoring device will send the drop count number and frequency to the server in real time through the wireless module, record the entire infusion process, and provide evidence-based data for the continuous quality improvement of nursing work, which greatly improves the convenience of infusion monitoring, can greatly reduce the probability of accidents during the infusion process, improve nursing work efficiency, reduce nurses' work pressure, reduce unnecessary repetitive work, and improve the safety of infusion nursing work.

In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of the present application.
