The liquid medicine remaining detection part is used to send the detected remaining medicine of the infusion bottle in the infusion state to the control system and the background monitoring system in real time. When the remaining medicine is in the critical area, the control system controls the needle advance and retreat control part to withdraw the needle , it should be noted that the critical area means that when the remaining amount of medicine is in the critical area, for safety considerations, the needle advance and retreat control part can withdraw the needle;

After the needle advance and retreat control part withdraws the needle, the control system controls the infusion bottle of the automatic bottle changing part to move to a position corresponding to the needle advance and retreat control part, and controls the needle advance and retreat control part to pierce the infusion bottle.

In this embodiment, the control system may be an ARM9 embedded control system.

From the above description, it can be seen that the automatic infusion set in this embodiment is composed of a liquid medicine residual detection component, a needle advance and retreat control component, an automatic bottle changing component, and a background monitoring system. Its mechanical structure and function realization scheme are as follows:

The liquid medicine residual detection part is used to detect the remaining medicine volume of the infusion bottle in the infusion state and feeds back to the ARM9 embedded control system in real time. The liquid medicine surplus detecting part can specifically be photoelectric sensor 6, and the quantity of photoelectric sensor 6 is two, and is all inlaid on the shell 12 of automatic infusion set; The bottle is located between two photoelectric sensors 6; there is a height difference between the photoelectric sensor 6 and the infusion bottle. The infusion bottle can be replaced when the remaining amount of medicine in the infusion bottle is in the critical area, and the photoelectric sensor 6 continuously transmits the acquired real-time data back to the ARM9 embedded control system. The real-time data obtained by the photoelectric sensor 6 can also be transmitted to the background monitoring system through the wireless data transmission module. The background monitoring system will display the data on the LCD screen after corresponding processing, and the medical staff can intuitively know the patient's infusion status from the LCD screen.

The automatic bottle changing part is provided with empty slots arranged at intervals, and a number of infusion bottles 1 can be placed in the empty slots, so that the infusion bottle 1 and the automatic bottle changing part move synchronously. When a certain infusion bottle 1 infusion is completed, the automatic bottle changing part drives The infusion bottle 1 moves until the next round of infusion work is completed. The specific structure of the automatic bottle changing part can be a rotating disk 2, the circumference of the rotating disk 2 is provided with empty grooves at intervals, the empty grooves can be arranged at equal intervals along the circumference of the rotating disk 2, and the empty grooves are used to place some upside-down bottles. In the infusion bottle 1, a polished rod 5 passes through the center of the rotating disk 2 and is fixed by a flange bearing 7. The polished rod 5 is connected with a stepping motor 3 through a transmission gear 4, and the stepping motor 3 is fixed on the shell 12. When the stepping motor 3 is in the working state, the stepping motor 3 rotates to drive the polished rod 5 to rotate, and the polished rod 5 drives the rotating disk 2 to rotate, and then the infusion bottle 1 is linked with the rotating disk 2 to realize automatic bottle changing of the infusion bottle 1. During the rotation of the infusion bottle 1 on the rotating disc 2, the infusion bottle 1 passes through two photoelectric sensors 6 in sequence, and the infusion bottle in the infusion state overlaps with the two photoelectric sensors 6, which facilitates the detection of the photoelectric sensors 6.

When the remaining amount of medicine is in the critical area, the ARM9 embedded control system controls the needle advance and retreat control part to withdraw the needle and pierce the next infusion bottle that moves to the set position. The critical area here means that the infusion bottle can be replaced when the remaining amount of medicine in the infusion bottle is in the critical area. The needle advance and retreat control components include a steering gear 10, a curved rod 9, a slider 8 and a needle head, the steering gear 10 is installed on the steering gear mount 11 and connected with the curved rod 9, the curved rod 9 is connected with the slider 8, and the needle is positioned on the slider 8 and according to the reciprocating motion of the slide block 8, the needle can be withdrawn or advanced selectively. It can be understood that several infusion bottles 1 are placed on the corresponding positions of the rotating disk 2, and the stepper motor 3 drives the polished rod 5 through the transmission gear 4 to rotate the rotating disk 2, so that the mouth of one of the infusion bottles 1 reaches the needle. Right above the advance and retreat control parts, at this moment, the steering gear 10 forwardly rotates by driving the curved rod 9 to make the slide block 8 embedded with the needle move upwards quickly, piercing the bottle mouth rubber stopper just above it, and infusion. When the photoelectric sensor 6 detects that the remaining medicine amount of the infusion bottle 1 in the infusion state is in the critical area, the steering gear 10 reversely rotates to make the slide block 8 move downward rapidly to realize needle withdrawal. Then the stepping motor 3 drives the polished rod 5 to rotate the rotating disk 2, so that the opening of the next infusion bottle reaches the needle head advance and retreat control part directly above, and repeats the above operation until all infusion bottles have been transfused.

The human-computer interaction function is completed through the human-computer interaction APP. The ARM9 embedded control system is also connected wirelessly with the mobile terminal. The mobile terminal is installed with an APP that provides a human-computer interaction interface. The mobile terminal can be a mobile phone or a computer. The computer interface sends interactive instructions to the app, such as online chatting with patients and medical institutions, professional medical consultation, etc., and the app also has functions such as online payment and doctor appointment. It is understandable that after the patient's family members download and install the corresponding APP, even if the family members are not with the patient, they can remotely understand the patient's real-time infusion status through the APP and issue an alarm. In addition, the APP also has chatting, consulting and payment functions, and family members can conveniently communicate and pay online with patients and various service windows of the hospital. The operating systems currently supported by the APP include iOS, Android, WindowsPhone and BlackberryOS. At present, the mainstream operating systems of smart mobile terminals include iOS, Android, WindowsPhone and BlackberryOS. APP supports the above mainstream operating systems and has strong portability.

The background monitoring system, the background monitoring system is connected with the liquid medicine residual detection part through a wireless device, and the liquid medicine residual detection part also includes a reminder device, when the remaining medicine of the last infusion bottle is in a critical area, the reminder device is used to send a reminder signal to the background monitoring system.

The workflow of the automatic infusion device in the present embodiment is:

First, the nurse puts several sterilized infusion bottles 1 on the rotating disk 2 of the automatic infusion set, each infusion bottle is turned upside down with the opening facing down, and the infusion bottles in the state of infusion are located on the two sides fixed on the shell 12. Between the photoelectric sensors 6, the rest of the infusion bottles do not overlap with the photoelectric sensors 6, and the photoelectric sensors 6 detect in real time whether the remaining drug volume of the infusion bottles in the infusion state is in the critical area, and transmit the detection data back to the ARM9 embedded control system and pass wireless The device is passed to the background monitoring system, and the background monitoring system will display the data on the LCD screen after corresponding processing, and the medical staff can intuitively know the patient's infusion status from the LCD screen.

Secondly, when the photoelectric sensor 6 detects that the remaining amount of medicine in the infusion bottle in the infusion state is within the critical area, the automatic infusion device will start to automatically change the medicine. During automatic dressing change, the ARM9 embedded control system controls the needle retraction of the needle advance and retreat control part. Since the needle advance and retreat control parts include a steering gear 10, a curved rod 9, a slide block 8 and a needle, the steering gear 10 is connected with the curved rod 9, and the curved rod 9 is also connected with the slider 8, and the needle is positioned on the slider 8 and moves according to the slider 8. The reciprocating motion can selectively withdraw or insert the needle, so the ARM9 embedded control system controls the steering gear 10 to drive the curved rod 9 to move down, and the curved rod 9 drives the slider 8 to slide down along the guide rail of the slider 8, so as to realize the needle retraction .

Again, the ARM9 embedded control system controls the rotation of the rotating disk 2, which can selectively rotate clockwise or counterclockwise according to the infusion sequence. The rotating disk 2 is driven by the stepping motor 3 and the polished rod 5 during the rotation process , when the infusion bottle moves to the top of the needle, the ARM9 embedded control system controls the steering gear 10 to drive the curved rod 9 to move upward, and the curved rod 9 drives the slider 8 to slide up along the guide rail of the slider 8, so that the needle can be inserted accurately and quickly Insert the needle into the infusion bottle.

It should be noted that when the remaining liquid medicine in the last bottle of infusion bottle is within the critical area, the wireless device will send a reminder to the nurse, and the nurse will go to help the patient pull out the line and stop the bleeding, which can avoid the occurrence of blood return. When the nurse forgets to pull out the needle for the patient, the patient can press the alarm device to send an alarm to remind the nurse.
