Description

Technical Field

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

[0002] In the infusion nursing process in outpatient and inpatient wards, the infusion alarm needs to be hung on the crossbar of the infusion stand by a suspension structure to complete the continuous liquid level monitoring.

[0003] Most conventional infusion alarms on the market use a fixed, integrated hook for suspension. The extension length of the hook is difficult to adjust, and it can only accommodate the height of a single type of infusion stand crossbar. The height and size of infusion stands equipped in different wards and beds vary significantly. When using a fixed hook to suspend the alarm, the overall suspension position is difficult to change flexibly. If the hook is too short, the entire alarm will be raised, requiring medical staff to raise their arms to view the flashing indicator lights and operate the function buttons, which increases work fatigue due to long-term repetitive operation. If the hook is too long, the device will sag significantly, and the casing may easily touch the patient's limbs and bedding. It may also entangle and squeeze the infusion tubing, causing tubing blockage and poor drug delivery. Therefore, a new type of infusion alarm is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an infusion alarm. By setting an adjustment component, specifically pressing the adjustment rod compresses a spring, causing the support plate and spring clip teeth to move. A squeezing plate presses the spring clip teeth down, disengaging them from the outer toothed storage plate. When the inverted U-shaped suspension hook is pulled outwards, the rope drives the outer toothed storage plate to rotate. The extension length of the suspension hook can be adjusted arbitrarily to match infusion stands of different heights. This solves the problem that most conventional infusion alarms on the market use fixed, integrated hooks, making it difficult to adjust the hook extension length and only suitable for a single specification of infusion stand crossbar height. Different wards and beds have significantly different infusion stand heights. When using fixed hooks to suspend the alarm, the overall suspension position is difficult to change flexibly. If the hook is too short, the entire alarm will be raised, requiring medical staff to raise their arms to view the flashing indicator lights and operate the function buttons, increasing work fatigue due to long-term repetitive operation. If the hook is too long, the device will sag significantly, easily touching the patient's limbs and bedding, and may also entangle and squeeze the infusion tubing, causing tubing blockage and poor drug delivery.

A clamping tube groove 110 is opened on the corresponding side of housing 111 and housing 212.

[0024] A specific application of this embodiment is as follows: The user first performs the opening and closing operation of the housing. Housing 111 and Housing 212 are opened and closed by rotating hinge blocks 119 on both sides. When operating the cover assembly 22, the slider 222 is pushed downwards, causing it to slide vertically downwards along the inside of the sliding cavity 221. The slider 222 slides outside the guide rod 223, simultaneously compressing the spring 224 sleeved on the outside of the guide rod 223. During the downward movement of the slider 222, it drives the back connecting plate 225 and the locking block 226 to move downwards synchronously. The locking block 226 moves from the vertical groove 228... The longitudinal groove 227 is disengaged and retracts from the opening 229, releasing the locking constraint between housing 111 and housing 212. At this time, housing 111 and housing 212 can be rotated outward to open, and the infusion tube can be placed between the clamping tube grooves 110 on both sides. After releasing the slider 222, the compressed spring 224 rebounds upward, pushing the slider 222, connecting plate 225, and locking block 226 to move upward as a whole. The locking block 226 is re-embedded into the longitudinal groove 227 and vertical groove 228, completing the closing and locking of housing 111 and housing 212. After the housing is closed, adjust the suspension height using the adjustment component 21 of the suspension mechanism 2. Press the button on the right end of the adjustment rod 218. The adjustment rod 218 moves into the cavity 212, and the limiting ring 210 simultaneously stretches the spring 219. The adjustment rod 218 drives the support plate 2111 and the spring clip 2112 to move synchronously. The obliquely arranged spring clip 2112 is squeezed downward by the compression plate 2113 and flips, releasing the engagement limit between the spring clip 2112 and the outer ring teeth of the outer tooth storage plate 213. Pull the inverted U-shaped suspension hook 211 outward, and the rope 2 14. As the inverted U-shaped suspension hook 211 is pulled out, the outer toothed storage plate 213 rotates around the fixed rod 215. When the outer toothed storage plate 213 rotates, it winds the inner worm gear 216. The worm gear 216 is stored in the hole 217 and undergoes torsional deformation. After adjusting the inverted U-shaped suspension hook 211 to the appropriate suspension length, the adjusting rod 218 is released. The spring 219 rebounds to the right and pushes the adjusting rod 218 to reset. The spring clip 2112 rebounds and re-engages with the outer ring of the outer toothed storage plate 213, locking the current pulled-out length. This completes the adjustment of the alarm's suspension height. After the height adjustment is completed, hang the inverted U-shaped hook 211 on the crossbar of the infusion stand to complete the suspension of the whole machine. After the equipment is powered on, the scanning module 113 on the front of the housing 111 can complete the patient bed scanning and binding. The LED flashing indicator 114, together with the speaker module 115, realizes the infusion sound and light reminder. The photoelectric liquid level detection module 116 on the back of the housing 212 collects the liquid signal of the infusion tube in real time. The button module 117 is used for switching equipment functions. The charging interface 118 is connected to the power supply to complete the equipment's power supply. After the infusion monitoring operation is completed, press the adjusting rod 218 again to unlock the outer toothed storage plate 213. The spiral 216 twists and the elastic force drives the outer toothed storage plate 213 to rotate, and the rope 214 is retracted into the cavity 212. The inverted U-shaped suspension hook 211 retracts simultaneously. The sliding block 222 slides down again to unlock the locking block 226, open the first housing 111 and the second housing 112, take out the infusion tube in the clamping tube groove 110, and complete the entire process of a single monitoring. It should be noted that the control of the barcode scanning module 113, LED flash indicator 114, speaker module 115, photoelectric liquid level detection module 116, and button module 117 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
