Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and more specifically, particularly relates to a light-proof bag liquid level sensing device. Background Art
[0002] During clinical infusion, the infusion drugs used include those that are easily photochemically decomposed or oxidized under light. These drug injections need to be prepared before use and dripped in the dark. For example, sodium nitroprusside is a fast-acting antihypertensive drug that will accelerate decomposition under light; for pyridine drugs, light has the greatest impact on their stability in infusion, so they also need to be operated in the dark; vitamins are sensitive to light, so when added to glucose injection and dripped, it is also necessary to avoid light; phenolic drugs are easily oxidized and deteriorated, so they should be used in the dark during clinical use.
[0003] Based on the above, the inventors discovered the following problem: since some drugs need to be kept away from light during the infusion process, medical staff will wrap a black bag around the infusion bag. This will cause the medical staff to be unable to observe the amount of drugs inside the infusion bag, and thus the infusion bag cannot be replaced in time after the infusion is completed.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a light-proof bag liquid level sensing device is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0007] Furthermore, a micro switch module, a battery pack module, a detection area copper sheet module, a buzzer module and an LED light module are respectively provided on one side of the PLC control chip.
[0008] Furthermore, a groove is formed at the top of the shell body, an LED lamp is embedded in the groove, and the LED lamp forms a signal connection with the LED lamp module.

[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model uses an arc groove in combination with a copper sheet and a copper sheet module in a detection area. The copper sheet can detect the flow of liquid level in a clamping position. When there is a lack of water in the infusion tube, the capacitance between the copper sheets changes, thereby triggering a signal to a PLC control chip. The PLC control chip processes the signal and performs an alarm operation through a buzzer module and a speaker. The LED lamp is used in combination with the LED lamp module to perform lighting operations at night and illuminate the bottom of the infusion bag, making it convenient for medical staff to replace the infusion bag. The design of a mounting hole in combination with a hand rope can prevent the device body from being lost. BRIEF DESCRIPTION OF THE DRAWINGS
