Portable drip alarm

Abstract

The invention discloses a portable drip alarm, which comprises an alarm component which is hung between a supporting bracket and an infusion bag; the portable drip alarm comprises a shell, a drum body and an alarm circuit, wherein the drum body is hung in the shell; a tension spring, a rod body and a columnar magnet, which are connected, are sequentially arranged on the drum body from top to bottom; a hook part, which is used for hanging the infusion bag, is arranged at the bottom of the columnar magnet; the alarm circuit is arranged in the shell and the alarm circuit comprises a reed switch, a light emitting diode and a buzzer which are connected in parallel; the reed switch is arranged at one side of the drum body and is arranged at the upper side of the columnar magnet; and the tension spring is such arranged that the reed switch is closed and the alarm circuit is connected when the columnar magnet shrinks backwards to be shortest by virtue of the tension spring. The portable drip alarm provided by the invention can remind a patient, family members and a duty room when medicine liquid runs out, so as to intercept air circulation between the infusion bag and a human body and to avoid harm to the patient caused by blood backflow; and the portable drip alarm is simple in structure and convenient to use, and the portable drip alarm has industrial production and popularization values.

Description

technical field [0001] The invention relates to a medical device. More specifically, the present invention relates to a portable drip alarm. Background technique [0002] Infusion is a commonly used treatment method in medical treatment. When the patient is in the hospital for infusion, it takes a long time and needs someone to take care of it, especially when the patient has no relatives to guard or infusion at night, the patient and the nurse are tired. Once the observation is not timely, the liquid medicine Accidents are likely to occur after dripping, and the patient's blood will flow back to the human body from the needle through the meridians, endangering the health or life safety of the infusion recipient. The electronic micro-infusion set can accurately adjust the infusion speed, but the cost is relatively high. Therefore, need a kind of portable drip alarm badly at present, can remind patient, relative and duty room when medicinal liquid drips, and interrupt infus...
