Fig. 2 is the infusion alarm circuit theory diagrams.
Among the figure: 1, lanyard; 2, display lamp; 3, initiating key is set; 4, hook; 5, keyboard; 6, on and off switch; 7, alarm; 8, transfusion measuring range actuator; 9, liquid container; 10, residual liquid; 11, display; 12, LOAD CELLS; 13, amplifier; 14, chip microprocessor; 15, analog scaling; 16, data storage.
The specific embodiment
As shown in Figure 1, this alarm comprises a weight detecting mechanism at least, and the hook 4 of weighing of weight detecting mechanism articulates with liquid container 9; The weight detecting mechanism panel is fixed with display 11, transfusion measuring range actuator 8 at least, and display 11, transfusion measuring range actuator 8 and alarm 7 are electrically connected with processing unit.
Open the on and off switch 6 on the weight detecting mechanism panel, display lamp 2 work on the panel, the power supply of description weight testing agency is normal.Transfusion measuring range actuator 8 is alloted to corresponding shelves, selected 100ml, 250ml, 500ml, 1000ml as transfusion measuring range, then transfusion measuring range actuator 8 is alloted on any one grade of 100ml, 250ml, 500ml, 1000ml.Liquid container 9 is hung on the hook 4, weight detecting mechanism can be suspended from eminence by lanyard 1, guaranteeing under the situation that liquid container 9 and weight detecting mechanism do not rock, press initiating key 3 is set, weight detecting mechanism compares the value of current sense weight value and data storage 16 storages, up near the value of data storage 16 storage the time, chip microprocessor place 14 is by alarm 7 output informations.Generally speaking, the setting value that transfusion measuring range actuator 8 is alloted is consistent with the liquid in the liquid container 9, just there is the residual liquid 10 of a permission in this, residual liquid 10 can be set in 20～25ml in this utility model when (comprising total amount of liquid in liquid container 9 and the disposable infusion set), alarm 7 sends chimes of doom, and the prompting transfusion is about to finish.
The former figure of infusion alarm circuit in this utility model can understand by Fig. 2.From circuit, claim to have points of resemblance, comprise LOAD CELLS 12, amplifier 13, chip microprocessor 14, data storage 16, display 11 and keyboard 5, but being finished of task is different with handheld electronic.
The output signal of LOAD CELLS 12 is electrically connected with the A/D input of chip microprocessor 14 through amplifier 13; The I/O mouth of chip microprocessor 14 is electrically connected with display 11, alarm 7 and transfusion measuring range actuator 8.
The bridge pressure sensor that LOAD CELLS 12 can adopt strain resistor to constitute, the analogue signal of its output is at first amplified through the preamplifier of low noise or measuring amplifier 13, is provided to the A/D change-over circuit then and carries out analog digital conversion and handled by chip microprocessor 14.Existing chip microprocessor 14 indoor designs have high-precision A/D change-over circuit, and therefore, the analog input mouth that the output signal of amplifier 13 is directly inputted to chip microprocessor 14 both can.
Certainly the same with traditional circuit sensor, amplifier, A/D converter and single-chip microcomputer (or special circuit), only be that A/D converter is integrated with single-chip microcomputer among Fig. 2.
The I/O mouth of chip microprocessor 14 or data port can directly be electrically connected with LCD display 11, keyboard 5, data storage 16, providing by I/O or data port needs data presented to be shown by LCD display 11, or imports various parameters by the keyboard 5 that I/O connects in data storage 16.LOAD CELLS 12 analog quantity input values as 100ml, 250ml, 500ml, 1000ml correspondence.Or the amount of residual liquid 10 is set in input.
Because chip microprocessor 14 has the A/D change-over circuit, a plurality of A/D are provided input port simultaneously, A/D input therein connects transfusion measuring range actuator 8 (adjustable resistors), regulating DC voltage by transfusion measuring range actuator 8 realizes the amount of liquid of liquid container 9 is input in the data storage 16 at any time, the signal that provides of 14 pairs of LOAD CELLSs 12 of chip microprocessor compares with the value that data storage 16 is set by transfusion measuring range actuator 8 at any time like this, as long as reach the value that residual liquid 10 is set.Alarm 7 sends chimes of doom, and the prompting transfusion is about to finish.
The single-chip microcomputer of band A/D change-over circuit is a lot of in this utility model, and as up-to-date F8051, mas430 or the like has teaching material to sell, and does not do too much description at this.Data storage 16 among Fig. 2 can adopt 24c02 24c016.
Use for convenience also to drive the size variation that one group of analog scaling 15 of being made up of LED shows transfusion measuring range actuator 8 set amounts, cooperate display 11 to show together by the I/O mouth of chip microprocessor 14.Analog scaling 15 is the columns that are connected in series with a plurality of LED, and each LED can be subjected to the control of I/O mouth.Analog scaling 15 it can give user a kind of impression easily.
