Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an infusion alarm. Background Technology

[0002] Nurses cannot accurately determine whether the medication has been successfully infused during shift handover. Existing infusion alarms can only trigger when there is no air. If a patient needs to receive medication while pumping medication, and the puncture site is blocked, the fluid from the pump may flow back to another path. In this case, neither the infusion alarm nor the infusion pump will trigger an alarm, making it impossible to determine whether the medication is being infused correctly or to detect the backflow of medication in a timely manner.

[0003] During intravenous infusion therapy, 41.8% of patients worried that improper care would cause the infusion to run dry. According to data on adverse drug reactions or events released by the National Adverse Drug Reaction Monitoring Center in 2020, adverse reaction events caused by injection accounted for 56.7% of the total, with intravenous injection accounting for 91.1% of these.

[0004] Patients are particularly concerned about the possibility of backflow of blood or even air embolism when receiving intravenous infusions at night, as they worry about not being able to remove the IV line in time after the infusion is finished, which can prevent them from sleeping soundly.

[0037] See Figures 1-10 As shown, this utility model provides an infusion alarm, which includes a housing 1, a light panel 2, an image acquisition module 3, a microcontroller 4, a speaker 5, and a power supply module 6. The housing 1 can be made of plastic and includes an inner cylinder 11 and a top cover 12. The inner cylinder 11 has a chamber 111 extending through its upper and lower ends, the size of which allows a Mofe's dropper to be fully inserted. The outer wall of the inner cylinder 11 has an elongated light-transmitting hole 112 communicating with the chamber 111, with its upper and lower ends adjacent to the upper and lower ends of the inner cylinder 11, respectively. The top cover 12 is connected to the upper end of the inner cylinder 11, and at least a portion of the top cover 12 extends radially inward along the inner cylinder 11. The side of the housing 1 has an insertion channel 15 communicating with the chamber 111 and extending through its upper and lower ends. The lamp plate 2 is embedded in the inner wall of the inner cylinder 11, with its upper and lower ends flush with the upper and lower ends of the light-transmitting hole 112, so that the light emitted by the lamp plate 2 can evenly illuminate the Mofe's dropper inserted into the chamber 111. The image acquisition module 3 can be a camera module, with the light-transmitting hole 112 located between the image acquisition module 3 and the lamp plate 2. The microcontroller 4 can be a PIC16F877A, electrically connected to the image acquisition module 3. The image acquisition module 3 transmits the acquired image information to the microcontroller 4, which analyzes and processes the received information to identify the liquid level in the Mofe's dropper. The speaker 5 is electrically connected to the microcontroller 4, which controls the power supply to the speaker 5. The power module 6 provides power to the infusion alarm, supplying power to the lamp plate 2, image acquisition module 3, microcontroller 4, and speaker 5. The image acquisition module 3, microcontroller 4, speaker 5, and power module 6 are all fixedly connected to the housing 1.

[0038] When in use, after the medical staff inserts the needle into the patient's vein, the medical staff holds the infusion alarm directly above the Mofe's drip tube, and through the insertion channel 15, the infusion tube enters the chamber 111 from the side of the housing 1. Then, the infusion alarm is moved down along the infusion tube, so that the Mofe's drip tube is inserted into the chamber 111 from below. Finally, the bottom cover 14 is placed on the upper end of the Mofe's drip tube, so that the infusion alarm is kept in a fixed position on the infusion tube.

[0039] After the infusion alarm is powered on, the light panel 2 illuminates the Mofe's drip tube. The image acquisition module 3 collects the image information of the Mofe's drip tube through the light-transmitting hole 112 in real time and transmits the collected image information to the microcontroller 4. Due to surface tension, the liquid level in the Mofe's drip tube is high on both sides and low in the middle. The special shape of the liquid level in the Mofe's drip tube will cause light to be reflected, so that in the image collected by the image acquisition module 3, the brightness of the liquid level in the Mofe's drip tube is different from that above and below the liquid level. Based on this phenomenon, the microcontroller 4 can analyze the relative height of the liquid level in the Mofe's drip tube. When the height of the liquid level in the Mofe's drip tube is lower than 30% or higher than 80%, the microcontroller 4 issues a control command to make the speaker 5 sound an alarm, alerting medical staff that there is an abnormality in the infusion. Since the light panel 2 illuminates the Moffield dropper, medical staff can observe the liquid level inside the dropper through the insertion channel 15, making it very convenient to use.

[0040] In this invention, the speaker 5 can also be replaced by an indicator light (not shown in the figure). When the liquid level in the Mofeet dripping tube is lower than 30% or higher than 80%, the microcontroller 4 sends a control command to make the indicator light illuminate, alerting medical staff that an abnormality has occurred during the infusion. In some embodiments, the infusion alarm can also be equipped with both the speaker 5 and the indicator light.

[0041] In this utility model, the housing 1 also includes a casing 13 and a bottom cover 14. The casing 13 is located outside the inner cylinder 11. The image acquisition module 3, the microcontroller 4, the speaker 5, and the power module 6 are located between the casing 13 and the inner cylinder 11. The edge of the top cover 12 is connected to the upper end of the casing 13. The bottom cover 14 is flush with the lower end of the inner cylinder 11. The edge of the bottom cover 14 is detachably connected to the lower end of the casing 13. The bottom cover 14 is provided with an inlet 141 that communicates with the chamber 111. The diameter of the inlet 141 is not less than the diameter of the chamber 111. The lower end of the insertion channel 15 is connected to the inlet 141.

[0042] like Figure 1 and Figure 8As shown, the casing 13 is a hollow quadrangular prism. The length and width of the casing 13 are both greater than the outer diameter of the inner cylinder 11, creating a space between the casing 13 and the inner cylinder 11 for installing the image acquisition module 3, microcontroller 4, speaker 5, and power module 6. The casing 13, top cover 12, and bottom cover 14 enclose the image acquisition module 3, microcontroller 4, speaker 5, and power module 6 within a sealed space. This not only makes the appearance of the infusion alarm more concise and aesthetically pleasing but also provides excellent protection for these components. More importantly, the lamp panel 2 in the infusion alarm can provide self-supplementary lighting. Its unique structural design effectively avoids interference from ambient light, thus improving monitoring accuracy.

[0043] See Figure 4 As shown, the enclosure 13 is provided with multiple sound outlets 131, and the speaker 5 is installed near the sound outlets 131. This facilitates the sound emitted by the speaker 5 to propagate outward, thereby enhancing the warning effect.

[0044] See Figure 10 As shown, the bottom cover 14 has a battery compartment 142 and a cover 143 covering the battery compartment 142. The power module 6 consists of multiple batteries located in the battery compartment 142. The batteries in the battery compartment 142 can be replaced by opening the cover. In some embodiments, the power module 6 can also be a rechargeable battery, and a charging interface is provided on the housing 1. This can avoid frequent battery replacements and help reduce usage costs.

[0045] In this invention, the chamber 111 is cylindrical, and its diameter is slightly larger than the outer diameter of the dropper. The width of the insertion channel 15 is smaller than the diameter of the chamber 111. Of course, in order to ensure that the infusion tube can enter the chamber 111 of the inner tube through the insertion channel 15, the width of the insertion channel 15 needs to be greater than the diameter of the infusion tube.

[0046] In this invention, the top cover 12 is provided with a U-shaped groove 121. The U-shaped groove 121 includes a first straight side 1211, an arc side 1212, and a second straight side 1213 connected in sequence. The first straight side 1211 and the second straight side 1213 are parallel. The arc side 1212 is a semicircle with its center coinciding with the axis of the chamber 111. The distance between the first straight side 1211 and the second straight side 1213 is equal to the width of the insertion channel 15. As shown in the figure, the open end of the U-shaped groove 121 is the upper end of the insertion channel 15. When there are two passages at the upper end of the Mofe's dropper, the structural design of the U-shaped groove 121 allows both passages to pass through simultaneously.

[0047] See Figure 10As shown, the lamp panel 2 includes a base plate 21, a lamp cover 23, and lamp beads 22. Multiple lamp beads 22 are fixed on the base plate 21 and encapsulated between the base plate 21 and the lamp cover 23. The lamp cover 23 can be made of white plastic. The lamp cover 23 can make the light emitted by the lamp panel 2 more uniform, which is beneficial for accurately detecting the liquid level in the Mofeet dropper.

[0048] To facilitate the installation of the lamp panel 2, a long, narrow mounting groove 113 is provided on the inner wall of the inner cylinder 11, into which the lamp panel 2 is inserted. For ease of use, a switch button 7 electrically connected to the power module 6 can also be provided on the housing 1, which controls the opening and closing of the infusion alarm.

[0049] During normal intravenous infusion, the fluid level in the Mofeet drip chamber is approximately 50% full. When the fluid level falls below 30% of the chamber's capacity, the infusion alarm will sound, alerting medical staff to an abnormality and ensuring that the infusion tubing is removed promptly after completion to prevent backflow or air embolism. Similarly, when the fluid level exceeds 80% of the chamber's capacity, the alarm will also sound, alerting medical staff to an abnormality and allowing them to promptly detect fluid backflow from the pump into another pathway and take appropriate action.

[0050] In summary, the infusion alarm provided by this utility model can monitor the entire infusion process. When abnormalities occur, it can issue an alarm to alert medical staff and patients, helping them to promptly detect these abnormalities and prevent adverse events such as backflow of blood, air embolism, and fluid reflux from the pump to another route. This provides great convenience to both medical staff and patients, allowing them to focus on other tasks and ensuring patients can sleep soundly at night. This infusion alarm is convenient to use, simple in structure, and low in manufacturing cost. It also helps reduce medical disputes between doctors and patients, and has a very broad application prospect.
