DETAILED DESCRIPTION The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-6 As shown, the present invention provides an intelligent infusion monitoring system, comprising: a base 1 detachably mounted on a dropper, and a liquid level acquisition module 3, a processing module 2, and an alarm module 4 respectively integrated on the base 1 and electrically connected; wherein, The liquid medicine level acquisition module 3 includes: an infrared sensor for collecting the liquid medicine level signal in the dropper in real time; The processing module 2 is used to receive and process the liquid medicine signal collected by the liquid medicine level acquisition module 3 to obtain liquid medicine level data, and calculate the liquid medicine height in the dropper in real time based on the liquid medicine level data using a liquid medicine level calculation formula, and trigger the alarm module 4 to sound an alarm when the liquid medicine level in the dropper is lower than a threshold value; The alarm module 4 is configured to issue an alarm when the processing module 2 calculates that the liquid level in the dropper is lower than a threshold value.

[0022] In the above solution, the dropper can be a Mofe dropper or a dropper made of other hard materials. The model of the processing module 2 is: TM32L4R9ZI processor; the model of the infrared sensor is: VCNL4040; wherein, the alarm module 4 includes: a buzzer.

[0023] An infusion tube is usually composed of three parts: a puncture needle, a catheter needle, and an infusion tube with a dropper, which are packaged separately and then packaged in a packaging bag. When in use, the medical staff unpacks the packaging bag and takes the infusion tube out of the packaging bag, connects the puncture needle to the end of the infusion tube located above the dropper, punctures the rubber stopper on the infusion bottle and inserts it into the infusion bottle. Then, the medical staff squeezes the dropper by hand to store a certain amount of liquid medicine in the dropper. Then, the base 1 is inserted into the dropper from the end of the infusion tube away from the puncture needle. During the assembly process, the liquid medicine level acquisition module 3 on the base 1 is ensured to be above the liquid level of the liquid medicine so that the light beam emitted by the infrared sensor of the liquid medicine level acquisition module 3 can be irradiated on the liquid surface. When the liquid medicine in the infusion bottle is used up, the liquid level in the dropper begins to drop, and the liquid medicine level acquisition module 3 is used to collect the change in the liquid medicine level in the dropper, and send the collected liquid level height signal to the processing module 2. The processing module 2 processes the received liquid level height signal and obtains the liquid medicine height in the dropper through the liquid medicine level height calculation formula. When the height value of the liquid medicine calculated by the processing module 2 is lower than the threshold value, the alarm module 5 is triggered to sound an alarm to remind medical staff to replace the infusion bottle or remove the needle.

[0024] In a preferred embodiment of the present invention, the liquid level calculation formula of the liquid medicine is: ; Where, D is the inner diameter of the dropper; R is the curvature of the infrared beam; : refractive index of air; : refractive index of the solution; : The initial light intensity measured when there is no liquid; : Liquid absorption coefficient; C: Ambient light interference compensation item.

[0025] In a preferred embodiment of the present invention, the base 1 includes: a card seat 101 and an adjustment seat 102 made of a transparent material; wherein, A C-shaped adjustment seat 102 is provided above the card seat 101 so as to be liftable via an adjustment mechanism 5 ; a liquid level acquisition module 3 is fixedly provided on the inner wall of the adjustment seat 102 , and the processing module 2 and the alarm module 4 are respectively fixed on the outer wall of the adjustment seat 102 .

[0026] In the above solution, a battery that provides power to the entire system is fixed on the adjustment seat 102, and the battery is electrically connected to the system through wires. The battery can be a button battery or a lithium battery. Less than 90°.

[0027] In the above scheme, the system also includes: a filtering processing module, which is used to filter the light intensity data collected by the liquid level acquisition module 3 through a mean filtering algorithm to eliminate noise and interference, and send the processed light intensity data to the processing module 2.

[0028] During use, the medical staff unpacks the packaging bag and takes out the infusion tube from the packaging bag, connects the puncture needle to the end of the infusion tube located above the dropper, and punctures the rubber stopper on the infusion bottle to insert into the infusion bottle. Then, the medical staff squeezes the dropper by hand so that a certain amount of liquid medicine is stored in the dropper. Then, the holder 101 of the base 1 is passed through the end of the infusion tube away from the puncture needle and assembled on the dropper so that the dropper is seated in the holder 101 and the adjustment seat 102, and the diameters of the holder 101 and the adjustment seat 102 are greater than or equal to the diameter of the dropper. Then, the distance between the adjustment seat 102 and the holder 101 is adjusted by the adjustment mechanism 5 so that the liquid medicine level acquisition module 3 (that is, the infrared sensor) on the adjustment seat 102 is located above the liquid surface of the liquid medicine, so that the light beam emitted by the liquid medicine level acquisition module 3 (infrared sensor) can be irradiated on the liquid surface.

[0029] When all the liquid medicine in the infusion bottle enters the dropper, as the infusion continues, the liquid medicine level in the dropper begins to drop. The liquid medicine collection module 3 can monitor the drop height of the liquid medicine in real time. When it is detected that the liquid medicine level in the dropper is lower than the threshold value, the processing module 2 triggers the alarm module 4 to sound an alarm to remind medical staff to replace the infusion bottle or remove the needle.

[0030] The intelligent infusion monitoring system provided by the present invention is not only capable of real-time online intelligent monitoring, but also has a small overall system size and reliable operation, thereby reducing usage and maintenance costs.

[0031] In a preferred embodiment of the present invention, the adjustment mechanism 5 includes: a lifting gear plate 501, a moving rod 502 and a locking head 503; wherein, The bottom end of the adjustment seat 102 is provided with a plurality of lifting gear plates 501 at equal intervals and vertically fixed along its circumferential direction, and the upper end of the card seat 101 is provided with a plurality of guide slots corresponding to and used in conjunction with all the lifting gear plates 501 at equal intervals along its circumferential direction, and the bottom end of each lifting gear plate 501 partially extends into each corresponding guide slot, and the card seat 101 is provided with a plurality of moving rods 502 corresponding to all the guide slots horizontally and movably at equal intervals along its circumferential direction, and one end of each moving rod 502 horizontally extends into the corresponding guide slot and is fixed with a lock head 503 that can be stuck in the lock slot formed between any two adjacent racks on the corresponding lifting gear plate 501.

[0032] In the above solution, when squeezing the dropper to partially allow the liquid in the infusion bottle to enter the dropper, the amount of liquid in the infusion bottle that initially enters the dropper may vary due to different squeezing forces applied by each medical staff member or other factors, thereby causing the liquid level in the dropper to vary. Therefore, it is necessary to adjust the liquid level acquisition module 3 and the liquid level in the dropper. The specific adjustment method is as follows: When in use, after the clamping base 101 and the adjusting base 102 are assembled on the dropper, all the moving rods 502 are moved horizontally to separate the locking heads 503 at their ends from the lifting gear plate 501, so that the lifting gear plate 501 is released from the locking relationship, so that the adjusting base 102 can be lifted upward to drive the liquid liquid level acquisition module 3 to rise to the appropriate position, and then all the moving rods 502 are moved again to drive all the locking heads 503 toward their corresponding lifting gear plates 501 until the locking heads 503 are stuck in the locking grooves formed between any two adjacent racks on the corresponding lifting gear plates 501, so as to lock the lifting plate 501 and prevent the adjusting base 102 from moving in the vertical direction after adjustment, so that the liquid liquid level acquisition module 3 is located above the liquid, so as to ensure that the light beam emitted by the liquid liquid level acquisition module 3 is irradiated on the liquid surface.

[0033] In a preferred embodiment of the present invention, a tensioning spring 8 is sleeved on each movable rod 502 located in the guide slot, and both ends of each tensioning spring 8 are fixed to the lock head 503 and the guide slot respectively.

[0034] In the above solution, the tension spring 8 is used to force the lock head 503 on the moving rod 502 to tightly abut against the lock groove formed between any two racks on the corresponding lifting gear plate 501 .

[0035] When the adjusting seat 102 needs to be adjusted, it is only necessary to pull the moving rod 502 to drive the lock head 503 at its end away from the corresponding lifting gear plate 501 until the lock head 503 is disengaged from the lifting gear plate 501. At this time, the tensioning spring 8 on each moving rod 502 is in a compressed state, thereby releasing the locking relationship of the lifting gear plate 501, thereby facilitating the movement of the adjusting seat 102. When the adjusting seat 102 is adjusted to a suitable position, the moving rod 502 is loosened so that under the action of the tensioning spring 8, each moving rod 502 drives the lock head 503 on its end toward the corresponding lifting gear plate 501 and tightly abuts against the locking groove formed between any two racks on the corresponding lifting gear plate 501, so as to lock the adjusted adjusting seat 102.

[0036] In a preferred embodiment of the present invention, a handle 6 is fixedly provided on the end of each lock head 503 located outside the base 101, and a support rod 7 is rotatably provided at the bottom end of each handle 6 through a damping shaft.

[0037] When the adjusting seat 102 needs to be adjusted, each of the moving rods 502 is pulled to drive the lock head 503 at its end away from the corresponding lifting gear plate 501 until the lock head 503 is disengaged from the lifting gear plate 501, and the support rod 7 on each handle 6 is rotated to make the free end of the support rod 7 rest against the clamping seat 101. When all the lock heads 503 are separated from all the lifting gear plates 501, the adjusting seat 102 can be pulled. When adjusted to the appropriate position, the support rod 7 is rotated in the opposite direction. Under the action of the tensioning spring 8, each of the moving rods 502 drives the lock head 503 on its end toward the corresponding lifting gear plate 501 and tightly rests against the lock groove formed between any two racks on the corresponding lifting gear plate 501, so as to lock the adjusted adjusting seat 102.

[0038] In a preferred embodiment of the present invention, a fixing seat 9 is horizontally fixed on the card seat 101, and the end portion of the fixing seat 9 away from the card seat 101 is recessed inward to form a C-shaped fixing slot, and a gasket 10 is fixed in the fixing slot.

[0039] In the above solution, after the base 1 is assembled to the dropper, it is fixed to the infusion pole used to support the infusion bottle through the fixing slot of the fixing base 9. The fixing slot is fixed with a gasket 10 adapted thereto to improve the stability and reliability of the fixing base 9 on the infusion pole.

[0040] The gasket 10 can be made of rubber or metal.

[0041] This embodiment also provides an intelligent infusion monitoring method, comprising the following steps: Step S1, assembling the base 1 on the dropper, and adjusting the height of the adjustment base 102 by the adjustment mechanism 5, thereby adjusting the height of the liquid level acquisition module 3, so that it is located above the liquid level of the liquid in the dropper; Step S2, collecting the liquid level signal of the liquid medicine in the dropper in real time through the liquid medicine level collection module 3, and pre-processing the collected liquid medicine level signal; Step S3, the processing module 2 calculates the liquid level of the current liquid in the dropper in real time according to the liquid level calculation formula of the liquid; Step S4: When the processing module 2 calculates that the liquid level of the medicine in the dropper is lower than the threshold, the processing module 2 triggers the 4 to sound an alarm to remind medical staff to change the medicine or remove the needle.

[0042] In a preferred embodiment of the present invention, the method for collecting the liquid level signal of the liquid medicine in the dropper in real time by the liquid medicine level acquisition module 3 and preprocessing the collected liquid medicine level signal comprises the following steps: Step S201: Establish a light intensity-liquid level relationship model. The infrared sensor emitter emits a light beam at an inclined angle toward the liquid surface in the dropper. The infrared sensor receiver receives the light beam signal generated by the emitter. The receiver sends the received reflected light intensity signal to the processing module 2. Based on the light intensity-liquid level relationship model, the relationship between the reflected light intensity I and the liquid level height h in the dropper is obtained as follows: ; in, : The initial light intensity measured when there is no liquid; : Liquid absorption coefficient; C: Ambient light interference compensation item; Step S202: Based on the relationship between the reflected light intensity I and the liquid level h in the dropper, the liquid level in the dropper can be reversely analyzed to obtain: ; Step S203: Periodically turn off the infrared sensor emitter to measure the ambient light intensity, and dynamically update the ambient light interference compensation item to obtain: Among them, the ambient light intensity is: ;Ambient light interference compensation item: C; Step S204: Using the three-dimensional liquid level compensation algorithm, the liquid level calculation formula can be obtained as follows: ; Where D is the inner diameter of the dropper (the standard inner diameter of the dropper is 6mm); R is the curvature radius of the infrared beam (subject to actual measurement); : refractive index of air (the refractive index of air is 1.0); : Refractive index of the drug solution (the refractive index of glucose is 1.34).

[0043] In the above scheme, the infrared sensor mainly consists of two parts: a transmitter and a receiver. The transmitter emits an infrared beam of a specific wavelength that illuminates the liquid surface in the infusion tube. Part of the light is reflected by the liquid surface and received by the receiver, which converts the received light signal into an electrical signal. Therefore, changes in the height of the liquid in the dropper cause changes in the intensity of the emitted light detected by the infrared sensor. A curve chart showing the relationship between the change in the reflected light intensity detected by the infrared sensor and the liquid height in the dropper is used. Specifically, by injecting liquid to a known height h into the dropper, for example, in increments of 5 mm, the reflected light intensity I detected by the infrared sensor is recorded. A curve chart showing the relationship between the change in reflected light intensity and the liquid height in the dropper is plotted to establish a light intensity-liquid level relationship model. Based on the light intensity values ​​collected by the infrared sensor, the current liquid height is calculated using interpolation or curve fitting. The relationship between the reflected light intensity I in step S201 and the liquid level h in the dropper is obtained as follows: ; in, : The initial light intensity measured when there is no liquid; : Liquid absorption coefficient; C: Ambient light interference compensation item.

[0044] And through reverse analysis, the liquid level height of the medicine in the dropper is: .

[0045] In order to reduce the error of the measured liquid level, the ambient light compensation method is used to periodically turn off the infrared transmitter and measure the ambient light intensity. , dynamically update C, and the environment intensity can be automatically updated every 30 seconds , thus obtaining: , using the three-dimensional liquid level compensation algorithm to obtain the liquid level calculation formula: .

[0046] In summary, the intelligent infusion monitoring system and method provided by the present invention overcome the problem in the prior art that manual monitoring of the infusion situation is required, and untimely monitoring may also cause certain safety hazards to patients.
