Example 2

This embodiment mainly introduces the utility model discloses a theory of operation and device work flow of each part.

This embodiment is based on embodiment 1, and the same points as embodiment 1 will not be described again.

Specifically, the operating principle of the infrared transceiver 3 is as follows: firstly, the infrared emitting diode and the infrared receiving triode are oppositely arranged on the same level, then the infusion tube is arranged in the groove 2 of the infusion tube and is fixed through the clamping groove 15 of the infusion tube, when the infusion tube contains liquid, the infrared emitting diode provides stable voltage and resistance to generate stable current, so that the infrared emitting diode emits stable infrared light, when the infrared light emitted by the infrared emitting diode passes through the infusion tube, the infusion tube and the liquid therein form a device similar to a convex lens because the liquid exists in the infusion tube at the moment, the infrared rays emitted by the infrared emitting diode are converged together, at the moment, more infrared rays are received by the end of the infrared receiving triode, the current is increased, and the side of the infrared receiving triode is connected with a resistor in series, the voltage drop across this resistor will increase at this time, since the supply voltage on the ir receiving side is stable and constant, resulting in a voltage drop on the other side of the resistor, so that a stable lower voltage will be generated on the ir receiving side as long as the ir emitting triode is stable.

If the liquid in the transfer line finishes flowing at this moment, lead to the state of liquid in the transfer line to change, thereby broken the device of convex lens before, the transfer line at this moment is owing to there is not the convergence effect of liquid, because the air's reason, let the transfer line at this moment and air constitute a device similar to concave lens, thereby disperse the infrared ray that infrared emission diode sent and come, lead to the infrared ray that infrared ray receiving triode received to reduce, thereby arouse the electric current to diminish, when the electric current of infrared receiving side is little, because the supply voltage that infrared receiving side voltage provided is stable unchangeable, so the voltage drop on the resistance can reduce this moment, thereby lead to the voltage rising of resistance opposite side. Therefore, in the process, the central control chip is used for detecting the voltage at the position at a fixed frequency, and the current state of the liquid in the infusion tube can be judged according to the difference value of the front voltage and the rear voltage.

A PNP type triode is added on one side of the infrared emitting diode, the PNP type triode is mainly used for controlling the on-off of the infrared emitting diode, after a start key is pressed down, the PNP type triode is in a saturated conduction state, the triode is conducted, the infrared emitting diode starts to work normally, when equipment is in a starting state and is not in a working state, the PNP type triode is in a cut-off state, the triode is in an open circuit, the infrared emitting diode is in a closing state, and power is not consumed at the moment.

Specifically, the buzzer alarm 4 is mainly used for sounding alarm when liquid is completely infused, and when the liquid is completely infused, the central control chip can send out a control signal to enable the buzzer alarm 4 to send out a short buzzer for prompting a patient that the liquid is completely infused.

Specifically, the LED warning light 5 mainly has the following five operating states, and the effects and meanings thereof are as follows:

1. the yellow lamp is long bright: when the first switch 6 is pressed down to start the machine, if the machine is successfully started, the system can send a short sound of 'dropping' by the buzzer alarm 4 to indicate that the machine is successfully started, at the moment, the yellow lamp is on for a long time to indicate that the system is initialized, the bed number can be set, and the system can enter a working state at any time.

2. Flashing a yellow light: when the second switch 7 is pressed to start, the system enters a working state, the central control module starts to detect the working voltage at the infrared transmitting and receiving module, and the yellow lamp flickers at a certain frequency to indicate that the system is in the working state at the moment.

3. The red light is long bright: the system can regularly detect battery voltage, and if the battery voltage is less than the value of setting for, central control module can send control signal, and the red light is long bright this moment, and the system can not get into normal operating condition this moment. When the charging is started, the red light is sent out and extinguished by the central control module.

4. Flashing a red light: when the liquid in the infusion tube is completely infused, the buzzing alarm 4 sounds to remind, the flashing yellow light of the normal work of the system is extinguished, the red light begins to flash, and the patient is reminded at the same time, and the infusion is finished.

5. The long-time illumination of the green light indicates that the system charging is completed, the system stops charging at the moment, and the state is maintained until the power supply is removed, and the green light is turned off.

Specifically, the liquid crystal display 11 realizes the display of the bed number through the control of the central control chip; when the third switch 8 is pressed to start the setting, the system controls the liquid crystal display 11 to flash and display, and the buzzer alarm 4 sounds for a short time to show that the setting mode is entered at the moment, so that the adjustment can be performed according to the actual bed position. Pressing the fourth switch 9 to increase the number of the bed, if the bed is pressed for a short time, adding 1 on the basis of the original bed and displaying, if the bed is pressed for a long time, increasing the bed value by the system at a certain frequency until the user releases the key; the same applies to the reduction of the bed number by pressing the fifth switch 10.

Specifically, the communication interface is communicated with the central control chip to obtain the running state and the operation command of the system, when the patient presses the second switch 7, the system starts to work, and at the moment, the system sends the currently set bed number and the starting state to the nurse station; since hospitals have different sizes, a wireless signal amplification chip is used to amplify power so that the signal can be transmitted to a remote place in order to be suitable for a larger hospital environment. After the wireless signal is transmitted, the control system enters a detection state of the infrared transmitting and receiving device, the communication interface enters a dormant state at the moment, if the control system detects that the liquid in the infusion tube is completely transported, the end state and the bed number information of the current bed number are sent to a nurse station under the control system, and then the communication interface enters the dormant state again. Therefore, no electromagnetic wave is sent in the whole infusion process, and no electromagnetic pollution exists. If the hospital is in a network-free state or the position of the patient does not have a mobile phone signal, the system can work normally.

Specifically, the motor driving chip has low-voltage power supply large-current output, overcurrent protection and overtemperature protection, and can rotate forward and backward. When the high level signal is input to the corresponding end, the chip controls the motor 12 to rotate forwards or reversely, so that the transmission part of the motor 12 can move forwards or backwards, the blocking and loosening of the infusion tube are realized, and the flowing of liquid in the infusion tube is controlled. When the liquid change in the infusion tube causes the voltage change of the infrared transmitting and receiving device, the central control chip transmits the control signal to the motor driving chip after the analysis of the central control chip, thereby achieving the purpose of controlling the rotation of the motor 12. When the motor 12 rotates forwards or backwards, the infusion tube can be blocked and opened through the transmission part of the motor 12.

Specifically, since the device is a portable device, the battery is a lithium polymer battery having advantages of high safety factor, no explosion, etc., and the nominal voltage of the lithium polymer battery is 3.7V. When the electric quantity of the battery is exhausted, the lithium battery needs to be charged, and at the moment, the LED warning lamp 5 displays that a red light is on; when the voltage of the lithium battery end reaches 4.2V, the battery is considered to be fully charged, and the LED warning lamp 5 is turned on in a green light mode, so that the lithium battery is fully charged. Although the nominal voltage of the lithium battery is 3.7V, the discharge of the lithium battery is stopped until the voltage of the lithium battery is discharged to the cutoff voltage of 3.0V since the voltage of the lithium battery is discharged from 4.2V.

For the on-off management, if the system is not provided with the on-off function, the system is theoretically always in the running state as long as the battery is connected, although the system can be in the low power consumption state through the central control chip, certain power can be consumed, and the system can run away after running for a long time. Therefore, in both aspects, a function of switching on and off is required. The first switch 6 is a power on/off button, which indicates power on/off when the first switch 6 is pressed, but actively turns off when the device is not used for a certain time.

Specifically, the central control chip is an STC8H series single-chip microcomputer, the single-chip microcomputer is a domestic chip and is an ultra-high-speed single-chip microcomputer newly developed by STC, a crystal oscillator, AD conversion and the like are arranged on the single-chip microcomputer, a large number of peripheral circuits can be saved, the area of a PCB is saved, and a large amount of space is reserved for other components.

The use process of this embodiment as shown in fig. 4 is:

s1, connecting the device with an infusion tube and starting up the device;

s2, setting a bed number;

s3, starting the device, and starting the device to run;

and S4, finishing infusion, and alarming and transmitting information by the device.

Specifically, the process of S1 is: the infusion tube is placed in the infusion tube groove 2 and fixed through the infusion tube clamping groove 15, the infusion tube is started after the first switch 6 is pressed, the key pressing time is longer than 1s, when the buzzer alarm 4 gives a short sound of 'dropping', the start is indicated to be successful, and at the moment, the LED warning lamp 5 is turned on in a yellow color, and the system initialization is finished;

specifically, the process of S2 is: pressing the third switch 8, the liquid crystal display screen 11 flickers for display, simultaneously the buzzer alarm 4 sounds for a short time, at the moment, the setting mode is entered, and the fourth switch 9 and the fifth switch 10 are pressed to adjust the bed number displayed on the liquid crystal display screen 11 for setting the bed number;

specifically, the process of S3 is: pressing second switch 7, starting drive, the device gets into the monitoring mode, and the system begins work, and the system can send the nurse station through wireless transmitting module with the current bed number that sets up and starting state, and LED warning light 5 presents yellow scintillation state this moment, and infrared transmitting receiving module begins the developments of control liquid, and liquid is defeated to accomplish.

Specifically, the process of S4 is: after the liquid is infused, the central control module controls the motor 12 to rotate forwards, controls the buzzer alarm 4 to give out alarm sound, displays that the infusion is completed on the liquid crystal display 11, and sends a signal to the nurse station through the wireless transmitting module, and the LED warning lamp 5 is in a yellow flashing state.
