Summary of the invention
In order to overcome the deficiency that the prior art versatility is poor, noise is big, the invention provides a kind of split type insulin pump, its CPU adopts dsp chip, has not only increased memory function, and makes insulin pump have that voice enter for and warning function; The design of usb circuit is used, can be by the versatility of insulin pump; Ultrasonic motor has replaced membrane pump, can reduce the use noise.
The technical solution adopted for the present invention to solve the technical problems: a kind of split type insulin pump, partly form by the controller part and the pump housing, its controller partly comprises CPU, display, keyboard, wireless communication module and interface circuit, display, keyboard, wireless communication module and interface circuit are electrically connected with CPU, its pump housing partly comprises CPU, wireless communication module, interface circuit, control circuit, power source, liquid storage box, the catheter case remaining needle, wireless communication module, interface circuit and control circuit are electrically connected with pump housing portion C PU, control circuit control power source passes through conduit with the liquid in the liquid storage box, remaining needle is sent into human body, be characterized in that described controller partial C PU is a dsp chip, the interface circuit that is connected in dsp chip is a USB interface, is connected with host computer by USB interface; The described pump housing partly has the USB interface that is connected in CPU, and its power source is a ultrasonic motor.
Described controller part also comprises the voice reporting read through model.
The invention has the beneficial effects as follows: because CPU adopted dsp chip, not only increased memory function, and made insulin pump have that voice enter for and warning function; The design of usb circuit is used, and has improved the versatility of insulin pump; Ultrasonic motor has replaced membrane pump, has reduced the use noise.
Below in conjunction with drawings and Examples the present invention is elaborated.
Description of drawings
Fig. 1 is the circuit block diagram of the split type insulin pump of the present invention.
Fig. 2 is the circuit block diagram of the split type insulin pump of prior art.
The specific embodiment
With reference to Fig. 1.The split type insulin pump of the present invention is divided into controller and two parts of the pump housing.Controller partly comprises CPU, display, keyboard, wireless communication module, interface circuit, voice reporting read apparatus and alarm.The pump housing partly comprises CPU, wireless communication module, interface circuit, control circuit, motor, liquid storage box, catheter case remaining needle.Controller partly adopts dsp chip TMS320F2812 as CPU.Utilize DSP integrated level height, processing speed is fast, stable performance, characteristics such as extensibility is strong, newly-increased following three functions: in (1) injection of insulin moment, information such as injected dose are sent into the DSP control chip by keyboard, and control information will show by the LCD liquid crystal display, when LCD shows, the voice reporting read through model will be exported voice signal synchronously; (2) when the battery electric quantity deficiency takes place, during situations such as liquid storage box surplus deficiency, DSP will enter for device to alarm and voice and send control instruction, and alarm sends alarm signal, and simultaneously, voice enter for the device voice that also will give a warning; (3) dsp chip also can pass through interface circuit USB, communicates with host computer, and with the injection of insulin moment of storage, information such as injected dose are imported host computer into, so that the data analysis in later stage.The wireless communication module that is connected with CPU adopts the nRF2401 module, carry out the information wireless transmission between the pump housing and the controller, the pump housing is worn on one's body the patient, and isolating with it controller can be provided with at any time at regular time and quantity, display screen and keyboard all design on controller, use more convenient.Under environment such as high-intensity magnetic field, unusual for avoiding wireless communication module take place to use, can be connected by USB interface between the pump housing and the controller, to guarantee accuracy insulin pump control.
As power source, input voltage is the 20V DC voltage to pump housing part by ultrasonic motor.Ultrasonic motor has following advantage: the moment of torsion weight ratio is big; Do not need reduction gear box; Response is fast, and control performance is good; The characteristic that cuts off self-lock is good; Noise is little; Can under conditions such as low temperature, vacuum, work; Shape variation, electric efficiency do not reduce with size and following degradation.The use of ultrasonic motor has reduced the noise of insulin pump, and is littler to each organ injury of internal organs of patient, also is easy to control, and safety is higher.
For the more weak gerontal patient of vision, operate very big difficulty by liquid crystal display.And instruct by voice broadcast, instruct the patient operate can, hommization serves for the patient more.
Described insulin pump can write down the injection time and the injected dose of each work, imports data into host computer by USB interface equally.
Described insulin pump is provided with alarm device, and is low at battery electric quantity, and under the insufficient situation of liquid storage box surplus, voice generators will send alarm voice, sends warning message on the LCD display simultaneously.
In pump housing module, adopt single-chip microcomputer as CPU, receive the information that controller sends by wireless communication module or USB interface, drive ultrasonic motor, and it is controlled in real time, ultrasonic motor drives piston with the insulin in the liquid storage box, passes through conduit, remaining needle is injected in patient's body.
The workflow that split type voice enter for the ultrasonic motor insulin pump is as follows: after the start, DSP, LCD display, single-chip microcomputer, wireless communication module etc. at first carry out initialization, produce inquiry message on the LCDs and " whether need voice guidance ", as selecting be, then begin voice and enter for workflow, after the keyboard scan program receives press key message, by DSP message is responded, and operating result is shown on the LCD screen, export corresponding voice reporting read message simultaneously, proceed keyboard scan subsequently; Then directly do not begin the keyboard scan program as selecting, no longer opening voice enters for function.When the keyboard scan program received shutdown command, each module quit work, the insulin pump shutdown.
In order to guarantee the safety in utilization of split type insulin pump, control signal is encoded the misoperation when avoiding not having the control signal input, being failure to actuate when control signal is arranged.The controller of insulin pump and the pump housing must be accomplished to concern one to one, carried out after dialogue confirms at controller and the pump housing, the controller of an insulin pump cannot be controlled the work of other pump housings, with the situation of avoiding a plurality of insulin pumps to interfere with each other in operation.In order to strengthen the safety that insulin pump uses, also be provided with alarm, insulin surplus deficiency in liquid storage box under the insufficient situation of battery electric quantity, warning message can occur on liquid crystal display screen, alarm sends alarm signal simultaneously, prompting user make-up solution is perhaps changed battery, will enter holding state in the pump housing simultaneously, ultrasonic motor quits work, to guarantee patient's safety.
