[0017] The upper and lower surfaces of the front cover 2 are both provided with a rotating ring 28, the outer surface of the rotating ring 28 is rotatably connected to the splint 3, the rear surface of the splint 3 is provided with a clamping block 6, the rear surface of the clamping block 6 is in close contact with the infusion tube 5, and a second hollow area 27 is provided in the middle of the splint 3. A first mechanical button 10 is provided near the right side of the front end of the front cover 2, and a speaker 11 is provided near the right side of the front end of the front cover 2. The speaker 11 emits sound alarms such as buzzing to remind the patient or accompanying personnel to pay attention.

[0018] The left inner wall of the groove 4 is provided with a slide groove 7, which is communicated with the interior of the front cover 2. The inner wall of the slide groove 7 is slidably connected with the extrusion block 8. The right end of the extrusion block 8 is in close contact with the infusion tube 5. A clamping space is formed by the groove 4 of the front cover 2 and the clamping block 6 of the clamping plate 3. There is no need to force the infusion tube 5 into the equipment cavity. The installation can be completed by simply clamping the device on the outside of the infusion tube 5 like clamping an object. The front end of the rear cover 1 is fixedly connected with the plug-in block 12. The front end of the plug-in block 12 is plugged into the front cover 2 through the slot 13. A photoelectric sensor 19 is horizontally provided at the lower end of the extrusion block 8. The right end of the photoelectric sensor 19 is facing the outside of the infusion tube 5. The sensor outputs a normal signal. When the infusion is nearing the end and an empty tube appears in the tube, the light propagation characteristics suddenly change. The sensor determines that the infusion is about to end by recognizing this feature and transmits the signal to the internal circuit board 9.

[0019] The calling robot 30 is provided with a mounting plate 20 at the front end of the calling robot 30, a calling device 26 is connected to the rear inner wall of the mounting plate 20, a strap 24 is rotatably connected to the left side of the mounting plate 20, and a limiting hole 25 is provided on the outer surface of the strap 24.

[0020] A snap ring 23 is provided at the right end of the mounting plate 20, and the outer surface of the snap ring 23 is engaged with the limiting hole 25. There are multiple limiting holes 25 and they are evenly distributed on the outside of the strap 24. A first hollow area 22 is provided in the middle of the mounting plate 20, and a second mechanical button 21 is provided at the front end of the calling device 26.

[0021] Working principle: The device realizes the full process automation of infusion status monitoring, automatic alarm, physical locking and remote calling through the coordinated operation of the infusion alarm 29 and the call robot 30. The infusion alarm 29 serves as the core execution end of monitoring, alarming and locking. First of all, in terms of convenient installation and fixation, it adopts an innovative structure imitating oxygen clamp. The groove 4 of the front cover 2 and the clamping block 6 of the clamping plate 3 form a clamping space. There is no need to force the infusion tube 5 into the device cavity. The installation can be completed by simply clamping the device on the outside of the infusion tube 5 like clamping an object. Turn the ring 28 The angle of the splint 3 can be flexibly adjusted to ensure that the clamping block 6 is in close contact with the infusion tube 5, which not only ensures the stability of the fixation, but also avoids excessive squeezing of the infusion tube 5 and affects the normal infusion. In the empty tube detection, its built-in photoelectric sensor 19 is facing the outside of the infusion tube 5 for real-time monitoring. When there is liquid in the infusion tube 5, the refraction and transmission characteristics of the liquid to light are stable, and the sensor outputs a normal signal. When the infusion is nearing the end and an empty tube appears in the tube, the light propagation characteristics suddenly change. The sensor determines that the infusion is about to end by identifying this feature and transmits the signal to the internal circuit board 9.

[0022] In the dual protection mechanism of alarm and locking, the sound alarm means that after the circuit board 9 receives the empty pipe signal, the speaker 11 is immediately triggered to emit a buzzer or other sound alarm to alert the patient or accompanying personnel. The optional locking function is that if the user turns on the locking mode in advance, the circuit board 9 will synchronously start the drive motor 14, and the motor will drive the rotating shaft 16 to rotate, and push the driven shaft 18 to slide along the slide groove 7 through the transverse rod 17, so that the extrusion block 8 moves toward the infusion tube 5, and finally cooperates with the inner wall of the groove 4 to clamp the infusion tube 5, physically blocking the flow of liquid, preventing blood backflow or air from entering the blood vessels, and avoiding medical risks. The user can customize whether to enable this function through the function toggle switch to meet risk management needs.

[0023] The calling robot 30 serves as the linkage end for automatically triggering the hospital calling system. In terms of flexible fixation and adaptability, it is fixed on the bedside call handle by a flexible strap 24. The limiting hole 25 of the strap 24 cooperates with the clamp 23 to flexibly adjust the tightness and adapt to different models of call handles. The installation is convenient and stable. In terms of wireless linkage and mechanical pressing, when the alarm 29 detects an empty pipe and triggers the alarm, its internal data transmission module will send a wireless signal to the calling robot 30. After receiving the signal, the calling robot 30 completes the physical pressing of the bedside call handle to simulate manual operation and realize automatic calling to the nurse station without the need for manual triggering by accompanying personnel.

[0024] Silent mode is a humanized design for contactless calling, and users can select this mode. At this time, the alarm 29 does not sound an alarm, but only sends a signal to the calling robot 30 through the data transmission module, and the robot completes the pressing of the calling button without feeling. This design reduces the alarm noise at night, avoids disturbing the rest of patients and accompanying personnel, and improves the comfort of use. The collaborative mode can flexibly adapt to different scenarios. Independent operation means that the alarm 29 can be used alone to only realize empty pipe detection and sound alarm, and the calling robot 30 is temporarily not working. Collaborative operation means that after the linkage mode is turned on, when the alarm 29 detects an empty pipe, it will synchronously trigger the sound alarm, optional locking and automatic calling of the calling robot 30, forming a closed loop of monitoring, alarm, protection and calling. In terms of manual control, the first mechanical button 10 of the alarm 29 can be used to pause the alarm and reset the device. The second mechanical button 21 of the calling device 26 supports patients to manually trigger calls to ensure flexible operation in emergency situations.

[0025] Example 2 1. The photoelectric sensor determines the infusion status by detecting the changes in the refraction and transmission of light in the liquid in the infusion tube 5. ) to indicate the change:

[0026] in: is the incident light intensity (reference value when there is no liquid flow).

[0027] is the absorption coefficient of the liquid (depending on the type of liquid).

[0028] is the path length of the liquid (i.e. the height or length of the liquid in the infusion tube 5).

[0029] When the amount of liquid in the infusion tube 5 is close to the tail end, the path length of the liquid will decrease, causing the light intensity Based on this change, the system determines whether there is an empty traffic control state.

[0030] When the light intensity Below threshold When the infusion is completed (empty tube state):

[0031] 2. When the photoelectric sensor 19 detects an empty tube, the alarm 29 sounds an alarm and transmits the signal to the alarm system. The circuit board 9 determines the infusion status and triggers the alarm:

[0032] in: Indicates that the alarm is triggered. is the alarm threshold of light intensity.

[0033] If the silent mode is enabled, the alarm 29 will not make a sound but will send a signal to the calling robot 30 via wireless communication.

[0034] 3. When the alarm 29 detects an empty tube and the user activates the locking function, the circuit board 9 controls the drive motor 14 to start, driving the rotating shaft 16, the transverse rod 17 and the squeeze block 8 to lock the infusion tube 5.

[0035] The locking action can be achieved by squeezing force ( ), the formula is as follows:

[0036] in: is the spring constant of the locking mechanism.

[0037] is the displacement of the extrusion block 8.

[0038] When the locking operation is completed, the liquid flow is blocked. is set to zero:

[0039] 4. After the alarm 29 detects the end of the infusion and issues an alarm signal, it sends a signal to the calling robot 30 through the wireless signal module. The pressing operation of the calling robot 30 can be expressed as the pressing force ( ):

[0040] in: is the spring constant of the robot's pressing force (depending on the hardness of the robot's pressing device), The displacement of the robot pressing the pager.

[0041] After the robot pressed the pager, the nurse received an automatic call signal.
