Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the indicator for indicating dropping empty of a medical infusion apparatus according to the embodiment of the present invention includes a sleeve 1, a mounting plate 2, a buzzer 3, a circuit board (not shown), a battery (not shown), and two strain gauges R1 and R2, where the sleeve 1 is used to be sleeved on a dropper of the medical infusion apparatus, the outer walls of two opposite sides of the sleeve 1 are respectively provided with a containing bin 11 and a battery bin 12, the mounting plate 2 is arranged in the containing bin 11, the circuit board is fixed on the mounting plate 2, the buzzer 3 is arranged outside the mounting plate 2 and electrically connected to the circuit board, the battery is arranged in the battery bin 12 and electrically connected to the circuit board, the two strain gauges R1 and R2 are attached to the inner walls of two opposite sides of the sleeve 1, and the circuit board is provided with two resistors R3 and R4, the two strain gauges R1 and R2, and the two resistors R3 and R4 to form a wheatstone bridge.
The housing compartment 11 and the battery compartment 12 may be formed in a square frame structure extending and protruding laterally on the outer wall of the sleeve 1, or may be formed by an opening on the outer wall of the sleeve 1, but not communicating with the inner wall of the sleeve 1.
