[0003] The existing Chinese patent CN117433603B discloses a metering device and a metering method for metering the residual liquid in an analgesic pump, which relates to the field of volume metering of the residual liquid in an analgesic pump, including a storage tank and a controller, wherein a liquid level sensor is arranged in the storage tank; a laser emitter capable of emitting laser is arranged at the top or above of the storage tank, and a tilt sensor capable of sensing laser is arranged at the bottom of the storage tank, and the laser emitter is located above the tilt sensor; the laser emitter, the liquid level sensor and the tilt sensor are electrically connected or signal-connected to the controller; the storage tank is connected to a discharge device for discharging the liquid in the storage tank. The invention can accurately measure the residual liquid of the analgesic pump after the use of the drug, so that the closed-loop management of the liquid dosage of the analgesic pump can be effectively realized.

[0004] The above-mentioned metering device needs to use multiple liquid level meters to monitor the liquid levels in multiple storage tanks respectively when measuring the liquid level inside the analgesic pump, which is relatively expensive. At the same time, if a liquid level meter is damaged, it will affect the final result of the test. Summary of the invention

[0006] A metering device for measuring the residual liquid in an analgesic pump comprises: a medicine storage box mechanism, a tilt judgment mechanism arranged inside the medicine storage box mechanism, an electronic liquid level meter installed on the inner wall of the medicine storage box mechanism, and a display control panel arranged outside the medicine storage box mechanism; the tilt judgment mechanism and the display control panel are electrically connected, and the electronic liquid level meter and the display control panel are electrically connected.

[0013] A metering system includes the metering device for metering residual liquid in an analgesic pump as described above, and also includes a microprocessor control module, a wireless communication module and an automatic alarm module.

[0014] Preferably, the microprocessor control module is electrically connected to the tilt sensor, the microprocessor control module is electrically connected to the display control panel, the microprocessor control module is electrically connected to the electronic liquid level meter, and the microprocessor control module is used to receive the remaining liquid amount signal and calculate the remaining amount of medicine and predict the depletion time according to a preset algorithm.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown:

[0024] Embodiment 1: The present invention provides a metering device for metering residual liquid in an analgesic pump, comprising: a medicine storage box mechanism 1, a tilt judgment mechanism 2 arranged inside the medicine storage box mechanism 1, an electronic liquid level meter 3 installed on the inner wall of the medicine storage box mechanism 1, and a display control panel 4 arranged outside the medicine storage box mechanism 1; the tilt judgment mechanism 2 and the display control panel 4 are electrically connected, and the electronic liquid level meter 3 and the display control panel 4 are electrically connected;

[0025] Among them, when the liquid level inside the medicine storage box mechanism 1 is stable, multiple tilt judgment mechanisms 2 simultaneously feed back information to the display control panel 4. When receiving the signal of liquid level balance, the display control panel 4 starts to read the reading of the electronic liquid level meter 3 and displays the liquid level height; when the liquid level shakes, the tilt judgment mechanism 2 follows the shaking. At this time, multiple tilt judgment mechanisms 2 cannot maintain a balanced state, and the display control panel 4 will not read the reading of the electronic liquid level meter 3 to avoid affecting the user's judgment.

[0026] Specifically, the medicine storage box mechanism 1 comprises a medicine storage box body 11 , and a medicine liquid inlet and outlet pipe 12 is fixedly connected to the outer side of the medicine storage box body 11 .

[0027] Specifically, a partition plate 13 is further disposed inside the medicine storage box body 11 , and the partition plate 13 divides the inside of the medicine storage box body 11 into an alarm area 131 and a measurement area 132 .

[0028] Specifically, a plurality of circular grooves are formed on the partition plate 13 , and mounting rods 14 are disposed in the circular grooves; the mounting rods 14 correspond to the tilt determination mechanisms 2 one by one.

[0029] Specifically, a plurality of limiting strips 15 are disposed on the upper side of the partition plate 13 , and the plurality of limiting strips 15 divide the interior of the medicine storage box body 11 into a plurality of parts.

[0030] As can be seen from the above, the medicine inlet and outlet pipes 12 can facilitate the injection and extraction of medicine. When the medicine is located inside the medicine storage box body 11, when the medicine shakes, the movement range of the tilt judgment mechanism 2 can be limited by a plurality of limit bars 15.

[0031] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the tilt determination mechanism 2 further includes a floating circular plate 21, and a tilt sensor 22 is provided on the upper side of the floating circular plate 21;

[0032] The tilt sensor 22 is responsible for monitoring the tilt state of the medicine storage box.

[0033] Specifically, one end of a light string 23 is fixedly connected to the lower side of the floating circular plate 21 , and the other end of the light string 23 is fixedly connected to a limiting ring 24 , which is sleeved on the outer side of the mounting rod 14 .

[0034] As can be seen from the above, the mounting rod 14 can play a positioning role on the limit ring 24, and the floating circular plate 21 can make the tilt sensor 22 follow the shaking of the liquid, while ensuring that the tilt sensor 22 is located on the upper side of the liquid level, and the floating circular plate 21 can be towed by the lightweight thin rope 23.

[0035] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that it also includes a metering system, including the metering device for metering the residual liquid in the analgesic pump as mentioned above, and also includes a microprocessor control module, a wireless communication module and an automatic alarm module.

[0036] Specifically, the microprocessor control module is electrically connected to the tilt sensor 22, the microprocessor control module is electrically connected to the display control panel 4, the microprocessor control module is electrically connected to the electronic liquid level meter 3, and the microprocessor control module is used to receive the remaining liquid amount signal and calculate the remaining amount of medicine and predict the exhaustion time according to a preset algorithm.

[0037] Specifically, the wireless communication module is electrically connected to the microprocessor control module, and the wireless communication module is used to transmit the remaining liquid information and warning signal to the monitoring terminal of the medical staff; the automatic alarm module is electrically connected to the microprocessor control module, and the automatic alarm module is used to remind that the liquid medicine is about to run out.

[0038] As can be seen from the above, when the liquid level is in the warning area 131, the tilt sensor is placed on the partition plate 13 in a balanced manner, and the reading measured by the electronic liquid level meter 3 is 0. At this time, the wireless communication module will transmit the remaining liquid information and the warning signal to the monitoring terminal of the medical staff, so as to replenish the analgesic pump liquid in time or stop using the analgesic pump. When the liquid level is in the measuring area 132, the tilt sensor floats on the upper side of the liquid through the floating circular plate 21. When the tilt sensor feeds back the balance signal to the microprocessor control module, the display control panel 4 will control the electronic liquid level meter 3 to detect the liquid level, and the detection result will be displayed on the display control panel 4. At this time, the user can conveniently know the remaining liquid depth;

[0039] The microprocessor control module is responsible for receiving signals from the tilt sensor, electronic level gauge and display control panel. It not only processes these signals, but also calculates the remaining amount of medicine and predicts the exhaustion time according to the preset algorithm, so that the system can provide real-time and accurate information about the remaining liquid status of the analgesic pump, providing decision support for medical staff;

[0040] The tilt sensor is responsible for monitoring the tilt state of the medicine storage box. When the medicine storage box is in a stable state, the sensor sends a signal to the microprocessor control module to allow it to measure the liquid level. Once shaking or tilting is detected, the sensor will adjust its state and prevent inaccurate liquid level readings from being recorded, thereby ensuring the accuracy of the measurement results;

[0041] The electronic liquid level gauge accurately senses the liquid level in the medicine storage box and converts it into an electrical signal to transmit to the microprocessor control module; the display control panel not only displays the current liquid level and remaining medicine information, but also may display the predicted time when the medicine will run out, so that medical staff can intuitively understand the status of the analgesic pump and make corresponding treatment accordingly;

[0042] When the remaining amount of medicine is lower than the preset safety threshold, the automatic alarm module will trigger an alarm signal. These signals can be transmitted to medical staff through sound, light flash or wireless communication to remind them that the medicine is about to run out and they need to replenish or replace the analgesic pump in time;

[0043] Through wireless communication, the system can transmit real-time residual fluid information and warning signals to medical staff, allowing them to remotely monitor the status of the analgesia pump and take intervention measures when necessary. This remote monitoring capability improves the efficiency and safety of medical care.
