Infusion alarm device

Abstract

The invention discloses an infusion alarm device. The infusion alarm device comprises a first light emitting module, a first light collecting module, a first comparison output module and a first alarmmodule, wherein the first light emitting module is arranged at the upper left / right portion of the outer portion of a Murphy's dropper and is used for generating directional illumination of a specific wavelength; the first light collecting module comprises at least two photosensitive resistors which are arranged at the side, opposite to the first light emitting module, of the dropper and different heights lower than the first light emitting module, and is used for sensing the illumination condition of the first light emitting module to generate a signal indirectly reflecting the liquid levelstate and outputting the signal to the first comparison output module; the first comparison output module is used for generating a reference voltage, comparing the reference voltage with a signal output by the first light collecting module and outputting an alarm control signal according to a comparison result; the first alarm module is used for giving an audible and visual alarm under the outputcontrol of the first comparison output module. The infusion alarm device has the advantage that by responding to the vertical floating change of the liquid level in the dropper during infusion, and using a buzzer or a flashing manner to prompt a guardian to perform processing, the infusion safety is improved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion alarm device for automatically monitoring the infusion process. Background technique [0002] The infusion set is a common medical device in hospitals. Its main function is to deliver the liquid in the infusion bottle or infusion bag to the patient's vein. When the infusion set is used, it is often necessary to observe the infusion situation at all times. When the infusion is completed, the medical staff Needle removal, dressing change, etc. [0003] At present, in the process of patients with needle infusion, each hospital often requires the patient’s family members to have a relative or nursing staff to monitor, closely monitor the progress of the infusion, and report the situation to the nurse in time. Because the infusion process takes a long time, some nursing staff Insufficient experience or lack of concentration often leads to nursing negligence: lighter on...

Problems solved by technology

[0003] At present, in the process of needle infusion for patients, each hospital often requires the patient's family members to have a relative or a nursing staff monitor, closely monitor the progress of the infusion, and report the situation to the nurse in time, because the infusion process takes a long time, and some nurses are Inexperience or lack of concentration often leads to nursing mistakes: mild ones, such as failure to find out that the needle was thrown out of the body in time, resulting in waste of medical solution, or venous blood reflux due to failure to shut down the medical solution after dripping; serious ones due to hanging time If it is too long, air enters the body, causing air embolism, or for some reason, the needle deviates from the vein, and the liquid injection enters the muscle and accumulates. If it is not detected and treated in time, it will cause local muscle swelling and increase the pain of the patient.
