Example 2:
as a second embodiment of the present invention, in order to control the infusion speed and facilitate the use of medical staff, the inside of the device box 1 is improved by the staff of the present invention, as shown in fig. 4 and 5, as a preferred embodiment, a circuit module 10 is installed on the left side inside the device box 1, a sensor 12 is installed on the right side of the circuit module 10, an arc buckle 9 is installed on the rear side of the device box 1, a display screen 5 is installed on the front side of the box cover 2 near the top end, and a reset button 6 and a start button 7 installed above the reset button 6 are installed on the left side of the display screen 5.
In this embodiment, the arc-shaped buckle 9 is made of a flexible plastic material, so as to facilitate subsequent fixing of the infusion tube 3, the power supply of the circuit module 10 is turned on by pressing the start button 7 to enable the circuit module to work, when the idle working mode is terminated by pressing the reset button 6, the CPU usually continues to execute a program from a next instruction for activating the instruction of the idle mode, and to complete an internal reset operation, a hardware reset pulse needs to keep two machine cycles (24 clock cycles) valid.
Furthermore, a transfusion tube 3 is arranged on one side of the arc-shaped buckle 9, a Murphy's dropper 4 is arranged on the transfusion tube 3, and the Murphy's dropper 4 is communicated with the transfusion tube 3.
Specifically, the arc-shaped buckle 9 is matched with the infusion tube 3 in a clamping mode, the infusion tube 3 can be clamped into the arc-shaped buckle 9, and the infusion dripping speed detection device is fixed on one side of the infusion tube 3 and is convenient to use.
Besides, the battery containing box 11 is bonded at the bottom end inside the device box 1 through glue, and the fixing plate 13 is bonded at the top end inside the device box 1 through glue, so that the stability of the infusion dripping speed detection device is ensured.
It should be noted that, as shown in fig. 6 and 7, a detection front-end circuit is provided in the circuit module 10, and the sensor 12 is mainly composed of an infrared emission tube and an infrared receiving tube. The infrared transmitting tube is driven by a constant power supply to transmit constant infrared rays. Infrared ray is reflected by an external object and then received by a receiving tube, and because of the problem of infrared ray power, a signal generated by a receiving circuit is very tiny and is a mV-level voltage, the signal needs to be amplified by an amplifying circuit to obtain an identifiable signal.
As shown in fig. 8, the amplifier is a homodromous ac amplifier composed of an integrated operational amplifier LM 324. The magnification factor is as follows: av ═ 1+ R4/R5. In this case, Av 1+500/22 23. After 23 times of amplification processing, the signals collected by the infrared photoelectric sensor can be easily processed.
Further, the amplified signal, whose high level and low level are not standard, cannot be directly identified and processed by the single chip, so that it is necessary to convert the non-standard pulse signal into the standard pulse signal by using a voltage comparator, which can compare the input voltage with the standard voltage, and the comparator outputs a voltage of 0 (low voltage) lower than the standard voltage. The comparator outputs high voltage (4-5V) higher than the standard voltage, so that signal conversion is completed, as shown in fig. 9, the integrated voltage comparator LM339 is used for voltage comparison, R7 is a potentiometer, the standard voltage is adjusted, R8 is a pull-up resistor, when no droplet is dropped, the receiving tube receives a signal and outputs low level, when a droplet is dropped, the dropped droplet has strong diffuse reflection, absorption and certain dispersion effects on infrared light, so that the received light intensity is changed greatly, the receiving tube cannot receive a strong signal, a long pulse is generated, but the signal is small, so that after being amplified by an operational amplifier LM342, a positive pulse signal can be output to the single chip microcomputer through the voltage comparator LM339, and accordingly, the number of droplets, namely the speed of the droplet, can be measured correctly through a fracture.
As shown in fig. 10 and fig. 11, the display screen 5 adopts a 1602 type LCD display module, and the 1602 type LCD display module has the characteristics of small volume, low power consumption, rich display content, and the like.
The 1602 type LCD can display 2 lines of 16 characters, has three control ports of 8-bit data buses D0-D7 and RS, R/W and EN, has an operating voltage of 5V, and has character contrast adjustment and backlight functions.
1602 employs a standard 16-pin interface, in which:
item 1: VSS is ground power.
And a 2 nd pin: VDD is connected with a 5V positive power supply.
And a 3 rd leg: v0 is the contrast adjusting end of the LCD, when it is connected to the positive power, the contrast is weakest, when it is connected to the ground, the contrast is highest, when the contrast is too high, it will generate ghost, when it is used, the contrast can be adjusted by a 10K potentiometer.
And 4, a 4 th pin: RS is register selection, selects a data register at high level and selects an instruction register at low level.
And a 5 th pin: RW is a read/write signal line, and performs a read operation at a high level and a write operation at a low level. The command or the display address can be written when the RS and RW are low level in common, the busy signal can be read when the RS is low level RW and the data can be written when the RS is high level RW.
And a 6 th pin: the E terminal is an enabling terminal, and when the E terminal jumps from a high level to a low level, the liquid crystal module executes a command.
7 th to 14 th pins: D0-D7 are 8-bit bidirectional data lines.
15 th to 16 th pins: and (4) empty feet.
It is worth to say that the display screen 5 and the circuit module 10 involved in this embodiment adopt the LCD display module with model 1602 produced by electronics limited company under Shenzhen Rui Tongtian, and its matching power supply and control switch can also be provided by the manufacturer, besides, the utility model discloses in involve that circuit and electronic components and module are prior art, technical staff in the field can realize completely, need not proud, the utility model discloses the content of protection also does not relate to the improvement to inner structure and method.
