Embodiment Construction
[0010] A human-computer interaction intelligent compression package for heparin injection, comprising an airbag 1, a pressure sensor 2 is arranged on the airbag, the pressure sensor is connected to an analog-to-digital conversion circuit 3, and the analog-to-digital conversion circuit is connected to a single-chip microcomputer 4, and the single-chip microcomputer receives the result obtained through the conversion of the analog-to-digital conversion circuit. The pressure sensor signal of the air bag is used to obtain the pressure of the air bag gas, and the air bag gas pressure is kept constant by inflating the air bag; The single-chip microcomputer control signal controls the opening and stopping of the air pump to realize the inflation of the air bag; the electric control air valve 7 controlled by the single-chip microcomputer is set on the pipeline between the air pump and the air bag, and the air bag is inflated and deflated through the reversing of the air valve; the singl...

The invention discloses a human-computer interaction intelligent pressing bag for heparin injection. A pressure sensor is arranged on an air bag, the pressure sensor is connected with an analog-digital conversion circuit, the analog-digital conversion circuit is connected with a single-chip microcomputer, the single-chip microcomputer is connected with an air pump supplying air to the air bag through a power driving circuit and is in circuit connection with the power driving circuit, the air pump is controlled to be started and stopped through weak single-chip microcomputer control signals, and air inflation of the air bag is achieved. An electronic control air valve controlled by the single-chip microcomputer is arranged on the pipeline between the air pump and the air bag, and the inflation and the deflation of the air bag are achieved by reversing the air valve. The single-chip microcomputer is connected with a human-computer interface, air bag pressure, remaining pressing time and alarming information are displayed on the human-computer interface, and starting and stopping buttons are arranged on the human-computer interface. The human-computer interaction intelligent pressing bag for the heparin injection is reasonable in structure, accurate in operation and good in effect.
Description
