Background technique
In today of medical technology rapid development, infusion pump and infusion controller using more and more extensive.It will with it
A small amount of liquid and drug is accurate, constant, constant speed, the feature being persistently pumped into human body, the routine become in operation and ICU treatment is set
It is standby.However infusion pump and infusion controller be other than the universal safety requirement that need to meet Medical Devices, while to meet its safety
The requirement of application specific standard.If the safety of product design cannot get necessary guarantee, that can bring huge to the use of user
Security risk, the serious registration for directly influencing product.Therefore the safety of product design is that can measurement product in city
The core technology and design objective being succeeded on field.
And the safe design framework of existing infusion pump commonly uses single-chip or uses the designed holder of dual chip
Structure.In the scheme system of single chip design, all controlling alarms are all completed by one chip, and existing dual chip
Design scheme is essentially all one as master chip, another is completed as auxiliary core piece, auxiliary core piece to master chip state
Other functions other than many safety are also carried while monitoring, the communication modes between followed by major-minor chip are relatively multiple
Miscellaneous, certain insecurity factor has also been introduced simultaneously in this, is finally exactly that auxiliary core piece cannot substantially accomplish completely self-contained alarm
Control.Although design of the existing dual chip design compared to single-chip has very big improvement in safety, but not simple enough
It is single reliable.
Summary of the invention
Object of the present invention is to: a kind of infusion pump and method with dual chip framework is provided, the risk of user is reduced, mentions
High patient uses the safety of infusion pump.
First technical solution of the invention is: a kind of infusion pump with dual chip framework comprising: master chip and master
The connected safety chip of chip, the logic unit being connected with the output of master chip and safety chip are connected with logic unit output
And be connected with master chip and safety chip system power supply, the motor power being connected with safety chip, the electricity that is connected with master chip
Machine driving, the first alarm unit being connected with master chip and the second alarm unit being connected with safety chip.
Based on the above technical solution, it further includes the following affiliated technical solutions:
First and second alarm unit is sound, light alarm, and the logic unit is logical AND gate.
First alarm unit is buzzer, and the second alarm unit is loudspeaker.
The master chip is input to by the Kick signal that a programmable input/output port generates a fixed frequency
Safety chip, and safety chip then by detection Kick signal whether the state extremely to judge master chip.
It include off-mode, startup self-detection state, normal activity states, alarm condition, etc. confirmation signal shape to be shut down
State and shutdown wait state.
Second technical solution of the invention is: a kind of method comprising following steps:
S1: master chip is input to peace by the Kick signal that a programmable input/output port generates a fixed frequency
Full chip；
S2: safety chip is by detecting Kick signal whether extremely come the state for judging master chip, if safety chip is examined
Master chip exception is measured, S3 is thened follow the steps, if safety chip detects that master chip is normal, executes normal workflow extremely
Terminate；
S3: safety chip is forced to stop the driving of motor by motor power control port, while passing through the first report of control
Alert unit starting alarm；
S4: safety chip provides alert activation signal to master chip by activation of alarm port, and master chip gets peace
Take the driving for stopping motor to terminating after the alarm signal that full chip is given to.
The invention has the advantages that:
The present invention reduces the complexity of product design, simultaneously effective solves one present on existing infusion pump safe design
A little disadvantages reduce the risk of user so that the safety of product obtains very big improvement, improve patient and use infusion
The safety of pump.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and embodiments:
Fig. 1 is structure chart of the invention；
Fig. 2 is the various state transition diagrams of chip in the present invention.
Fig. 3 is the pin function figure of master chip in the present invention.
Fig. 4 is the pin function figure of safety chip in the present invention.
Fig. 5 is the circuit diagram of motor power circuit in the present invention.
Specific embodiment
Embodiment: as shown in Figs. 1-5, the present invention provides a kind of specific implementations of infusion pump with dual chip framework
Example comprising: master chip, the safety chip being connected with master chip, the logic list being connected with the output of master chip and safety chip
Member exports with logic unit and is connected and the system power supply being connected with master chip and safety chip, the motor being connected with safety chip
Power supply, the motor driven being connected with master chip, the buzzer being connected with safety chip and the loudspeaker being connected with master chip.Electricity
Machine driving could only drive under the precondition for having power supply, and what safety chip controlled is the power supply of motor drive module.It is main
Chip, safety chip pin function figure see Fig. 3-4, and motor power circuit is as shown in Figure 5.
As shown in Figure 1, master chip and safety chip can be transferred through power button and carry out electrification reset in conjunction with shown in Fig. 3-4,
The output of the two is by logic unit or circuit come control system power supply.Only when master chip and safety chip power down simultaneously
It waits, system just meeting power down, this makes the power supply safety of system be fully protected.Master chip and safety chip by controlling respectively
Loudspeaker and buzzer processed are alarmed, and only when the two fails simultaneously, alarm system just fails, this enable the system to for
User provides obvious alarm.By several simply programmable input/output ports come real between master chip and safety chip
The interaction of existing information and the monitoring of state mainly include Kick signal, alert activation signal and shutdown confirmation signal.Master chip is logical
It crosses the Kick signal that a programmable input/output port (i.e. No. 87 pins) generates a fixed frequency and is input to safety chip
No. 9 pins.Safety chip by detection Kick signal whether the state extremely to judge master chip.If safety chip detects
To master chip exception, safety chip passes through motor power control port first to be forced to stop the driving of motor, while passing through control
Buzzer starting alarm, No. 88 for providing alert activation signal to master chip finally by activation of alarm port (No. 8 pins) are drawn
Foot.Master chip takes corresponding safety measure after it can get the alarm signal that safety chip is given to.
Master chip and safety chip main definitions off-mode, startup self-detection state, normal activity states, alarm shape
State, etc. confirmation signal state to be shut down and shutdown wait state.A state transition diagram between various states is as shown in Figure 2.
Compared with prior art, the duplicate protection that the present invention is controlled by power supply first, followed by passes through simple programmable
Input/output port carries out Kick signal and alarm signal carries out the monitor mode and design of simple information interaction, is finally exactly to pass through
The controlling alarm design method of master chip and safety chip independent control alarm generator, reduces the risk of user, improves
Patient uses the safety of infusion pump.
Although having made specific descriptions to the present invention referring to the above embodiments, for the ordinary skill people of this field
For member, it should be appreciated that can not depart within spirit and scope of the invention based on present disclosure progress
It modifies or improves also all within spirit and scope of the invention.
