Transfusion alarm system adopting near-infrared photoelectric sensing device

Abstract

The invention discloses an infusion alarm system adopting a near-infrared photoelectric sensing device. The infusion alarm system comprises an upper infrared photoelectric sensor, a lower infrared photoelectric sensor, a fixing clamp, a single chip microcomputer and a display screen. The upper infrared sensor and the lower infrared sensor are respectively arranged on the fixing clamp; the upper infrared sensor and the lower infrared sensor are connected with the single-chip microcomputer through two ports respectively. The fixing clamp comprises a first clamping arm, a second clamping arm, a fixing base and a driving structure. The fixing seat is fixed on an infusion support, the first clamping arm and the second clamping arm are arranged in a crossed mode and are arranged on the fixing seat through a rotating shaft in a scissor-type rotating mode, and the driving structure is arranged on the rear side of the first clamping arm and the rear side of the second clamping arm. The infusion alarm device has the advantages that the infusion alarm device is accurate in alarm, possible error defects in infusion procedures can be effectively prevented, the reasonability of various links in the whole infusion procedures can be guaranteed, safe and comfortable infusion atmospheres can be created, and the infusion nursing quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of liquid level monitoring of infusion bottles, and in particular relates to an infusion alarm system using a near-infrared photoelectric sensing device. Background technique [0002] In the clinical infusion nursing work, the hospital intravenous infusion nursing mostly adopts the traditional manual monitoring method, that is, when the patient's infusion is finished or the infusion flow rate is not appropriate, the nurse is artificially notified to deal with it. This method requires the dual monitoring of medical staff and the patient's family. If the family monitoring is not in place during the patient's infusion process or the medical staff is busy and fails to deal with it in time, it is often prone to air embolism and other infusion accidents, and even endanger the patient's life in severe cases. Safety, resulting in related medical disputes or medical malpractice. The current design principles of vari...

Problems solved by technology

[0003] Aiming at the defects and problems existing in the existing equipment, the present invention provides an infusion alarm system using a near-infrared photoelectric sensing device, which effectively solves the problem that the existing equipment is easily affected by the shape, color, and material of the detected object during the infusion monitoring process. Influenced by external environment and other factors, the monitoring level is inaccurate, resulting in false alarms; the device cannot upload feedback immediately after receiving the signal, so that patients and medical staff cannot clearly and intuitively pay attention to the current infusion status, so that medical staff Unable to make reasonable predictions in advance and prepare medical supplies related to infusion nursing work, resulting in hidden dangers such as drip speed errors, liquid dripping empty, needle blood return, and needle blockage during the infusion process, causing patients to encounter these infusion risks. treatment, unnecessary bodily harm
