Abstract

The invention relates to the technical field of intravenous infusion, and discloses an alarm device for preventing blood return during infusion. A first clamping support elastic sheet (1) and a secondclamping support elastic sheet (2) are arranged to form an included angle with narrow bottom and wide top, the bottom ends of the two are fixed on a positioning mechanism (3), and the top ends are respectively fixed on a first clamping conduction mechanism (4) and a second clamping conduction mechanism (5) symmetrically disposed. First magnets (401) of the same polarity are fixed at two ends of the first clamping conduction mechanism, and second magnets (501) of the polarity different from that of the first magnets are fixed at two ends of the second clamping conduction mechanism. An alarm device (6) is disposed on the first clamping conduction mechanism or the second clamping conduction mechanism, and the alarm is connected to internal circuits of the first clamping conduction mechanismand the second clamping conduction mechanism through wires. Compared with the prior art, the alarm device can automatically remind a doctor and a patient that the injection is about to be infused, avoid the phenomenon of blood return and improve the infusion safety.

Description

technical field

[0001] The invention relates to the technical field of intravenous infusion, in particular to an alarm device for preventing blood backflow during infusion. Background technique

[0002] Intravenous infusion refers to the continuous and stable injection of large doses of liquid into the human body through veins to supplement the body fluids, electrolytes or provide nutrients for the infusion, so as to make the patient recover quickly; in the medical work, infusion is very common , usually the injection is hung upside down on a water hanger with a certain height, and then injected into the human body through a hanging needle;

[0003] Because the speed of infusion is relatively slow, the volume of infusion is different, and the time of infusion cannot be controlled. Infusion patients are prone to sleep during the long infusion process, especially at night or even in the middle of the night. When the injection in the infusion bag is about to be infused, if the...
