Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically a novel infusion alarm. Background Technology
[0002] As a routine clinical medical device, the typical structure of an intravenous infusion device consists of four main modules: a suspended reservoir, a puncture assembly, a catheter system, and a mechanical flow controller. The puncture assembly's input end is immersed in the reservoir, and its output end is connected to the catheter system. The infusion rate is adjusted by manually operating the mechanical flow controller. The current technical bottleneck in clinical practice is mainly reflected in the sequential infusion of multiple fluids: when the first bottle of medication is about to be finished, it is necessary to rely on the patient or caregiver's manual visual monitoring and to request a bottle change from the medical staff. This operation mode has three significant drawbacks: (1) it leads to a waste of time and resources for non-professional caregivers; (2) nursing staff have to deal with randomly distributed fluid change requests, resulting in an unpredictable surge in workload; (3) the lack of timeliness in the bottle change operation can easily cause anxiety in patients, creating a risk of secondary psychological trauma.
[0003] This invention relates to a novel infusion alarm that addresses the issues of not automatically alerting when the IV drip solution runs out and not automatically switching between different IV drip types. Utility Model Content

The first sliding groove is used for guiding and limiting the sliding clamp, and the sliding clamp is used for clamping the infusion tube to stop the infusion and prevent backflow of blood.
[0007] As a preferred technical solution of this utility model, a second sliding groove is formed on the second groove of the second component. The second sliding groove is the same as the first sliding groove. The second sliding groove is used to make way for the sliding clamp and prevent interference.
[0008] As a preferred technical solution of this utility model, the first component includes a control board, and the control module, infrared module and buzzer are soldered to the control board. The control module includes a microcontroller, a WiFi module and a Bluetooth module.
[0009] As a preferred technical solution of this utility model, the first magnetic contact inside component one has a first contact terminal, which is electrically connected to the control module. The second magnetic contact inside component two has a second contact terminal, which is electrically connected to the buck-boost voltage regulator chip.

[0010] As a preferred embodiment of this utility model, the second component has a charging port on its top, and the charging port is electrically connected to the buck-boost voltage regulator chip.
[0011] As a preferred technical solution of this utility model, anti-slip textures are provided on both sides of component one and component two, which can prevent hand slippage and increase friction when separating component one and component two.
[0012] As a preferred embodiment of this utility model, a buzzer hole is provided on the rear cover at the corresponding position of the buzzer to facilitate sound transmission.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model designs the overall structure into two components, and the first magnetic contact and the second magnetic contact attract each other and are energized, so that it can be quickly installed into the designated position of the infusion tube during use.

[0017] Example 1 like Figures 1 to 10 As shown, this utility model discloses a novel infusion alarm device. The technical solution includes an alarm 2 and a motor 11. The alarm 2 includes a first component 3 and a second component 4. Anti-slip textures 24 are provided on both sides of the first component 3 and the second component 4. A first groove 5 and a second groove 6 are present on the first component 3 and the second groove 6. A first sliding groove 301 is formed in the second groove 6 of the first component 3. A sliding clamp 10 is located within the first sliding groove 301. Bearing seats 8 are located on both sides of the first sliding groove 301 inside the first component 3. A bidirectional lead screw 9 is rotatably connected to the bearing seats 8. A second groove 401 is formed on the second groove 6 of component 2 4. The second groove 401 is the same as the first groove 301. An infrared transmitter 17 and an infrared receiver 7 are on the first groove 5. A liquid-stopping mechanism 25 is on the second groove 6. The liquid-stopping mechanism 25 includes a bidirectional lead screw 9. The bidirectional lead screw 9 is located inside component 1 3. A sliding clamp 10 is engaged on the bidirectional lead screw 9. A motor 11 is located at the other end of the bidirectional lead screw 9. The output shaft of the motor 11 is connected to the bidirectional lead screw 9. A control board 12 is located inside component 1 3. A control module 13 and an infrared receiver 7 are welded onto the control board 12. Module 14 and buzzer 15; control module 13 includes a microcontroller, WiFi module, and Bluetooth module; component 13 has a back cover 302; buzzer hole 19 is opened on the back cover 302 at the corresponding position of buzzer 15; touch screen 18 is on the back cover 302; component 24 contains battery 20 and buck-boost voltage regulator chip 21; component 13 has a first magnetic contact 16; the first magnetic contact 16 has a first contact terminal 1601; the first contact terminal 1601 is electrically connected to control module 13; control module 13 is connected to motor 1. 1. Buzzer 15, infrared module 14, and touch screen 18 are electrically connected. Component 2 4 has a second magnetic contact 22, and the second magnetic contact 22 has a second contact terminal 2201. The second contact terminal 2201 is electrically connected to the buck-boost voltage regulator chip 21. The buck-boost voltage regulator chip 21 is electrically connected to the battery 20. Component 1 3 and Component 2 4 are attracted to each other through the first magnetic contact 16 and the second magnetic contact 22 to form a whole. Component 2 4 has a charging port 23 on top, and the charging port 23 is electrically connected to the buck-boost voltage regulator chip 21.
[0018] The working principle of this invention is as follows: During infusion, components 3 and 4 of the alarm 2 are separated and attracted to each other at the drip bottle 102 via the first magnetic contact 16 and the second magnetic contact 22, causing components 3 and 4 to snap onto the drip bottle 102. At this time, the battery 20 powers the control module 13, which controls the operation of the alarm 2 via the touch screen 18. When the medicine drop is dripping normally in the drip bottle 102, the medicine drop will intermittently block the infrared transmitter 17 and the infrared receiver 7. At this time, the control module 13 determines that this state is normal. In this state, the liquid-stopping mechanism 25 will not operate. When there is no medicine in the IV bottle 1, no more medicine will drip from the drip bottle 102, and no medicine will pass between the infrared transmitter 17 and the infrared receiver 7. If no medicine drip is detected within five seconds (this time can be customized on the touch screen 18), the control module 13 will determine this state as an abnormal state. The control module 13 will control the motor 11 to rotate, and the output shaft of the motor 11 will drive the bidirectional lead screw 9 to rotate. The two sliding clamps 10 will move closer to each other, clamping the IV tube 101 flat, thus stopping the liquid flow. To achieve automatic fluid replacement, the infusion tubing 101 sections of multiple drip bottles 102 and below need to be connected via multi-port connectors 26, and an alarm 2 should be installed at each drip bottle 102. Figure 9 As shown, the setup program is performed on the touch screen 18. Multiple alarms 2 can be linked together through the microcontroller, WiFi module, and Bluetooth module on the control module 13. At this time, the liquid-stopping mechanism 25 of the alarm 2 on the first bottle of medicine is in the open state, while the other liquid-stopping mechanisms 25 are in the closed state. This enables the first bottle of medicine to automatically alarm and stop the liquid flow, and controls the liquid-stopping mechanism 25 of the alarm 2 on the second bottle to open, thereby realizing automatic liquid replacement.
