Description
Affiliated field
The present invention relates to portable medical device, especially micro-injection pump.
Background technology
Micro-injection pump is a kind ofly can be widely used in each section office of hospital accurately to the Medical Devices of venous patient injectable drug.Currently marketed micro-injection pump generally can only be supported the syringe of limited quantity producer, and perhaps its scaling method relies on measuring cup, balance, rule isometry weighing apparatus.Because disposable syringe producer is numerous, specification is various, leans on the limited manufacturer data of storage when dispatching from the factory in the machine, far can not be suitable for the nearly syringe of hundred kinds of specifications that all hospitals use.Rely on conventional scaling method complex steps again, the people is that the error that causes is bigger.
It is that detailed syringe size data are deposited among the EEPROM of control circuit that existing micro-injection pump uses the method for syringe, when each user uses micro-injection pump, need to select the syringe model of use, because the finite capacity of the inner EEPROM of syringe, the syringe specifications parameter of all brands all can not be deposited among the EEPROM, and the syringe of producer's same specification different batches also has scale error.
We are badly in need of having a kind of system and method that can measure the syringe specifications parameter in real time so, just can accurately measure the specifications parameter of any disposable syringe by shirtsleeve operation, overturn the conventional thought of deacclimatizing machine by syringe, look for another way, provide the implementation method of the specifications parameter of machine recognition syringe, make micro-injection pump can be suitable for the syringe of all brands.
Summary of the invention
Be suitable for the problem of all brand syringes in order to solve identification syringe specifications parameter, the present invention proposes a kind of simple system and method, can measure the specifications parameter of any disposable syringe exactly, thereby make micro-injection pump be suitable for all on the market syringes.
The present invention is achieved in that

The pull-up displacement of the pull bar 15 by stationary installation 18 detects syringe 4 nominal volume specifications, according to the displacement data of cylinder piston 3 and the nominal volume specification of syringe 4, obtain interior sectional area.
Specifically,
Micro-injection pump syringe size labeling system, comprise fore shell 1, back cover 2, cylinder piston 3, syringe 4, propulsion plant 5, control circuit 6, control panel 7, fore shell 1 is formed a cavity box body with back cover 2, control circuit 6 places the inside of cavity, syringe 4 is fixed on the fore shell by stationary installation 18, cylinder piston 3 and fixedly clamping of propulsion plant 5.
Control circuit comprises CPU8, signal acquisition circuit 9, motor-drive circuit 10, optoelectronic switch 11, eeprom12.
CPU8 sends gating pulse to motor-drive circuit 10, and writes down the gating pulse number; Motor-drive circuit 10 comes drive stepping motor 13 to rotate according to umber of pulse.Motor-drive circuit 10 whenever receives a pulse, rotates a fixed angle with regard to drive stepping motor 13, makes the push rod 14 fixing displacement of advancing.Because push rod 14 and fixedly clamping of cylinder piston 3 so when gating pulse of the every transmission of CPU, can draw the displacement that cylinder piston 3 advances according to calculating.Drive propulsion plant 5 by control circuit 6, the meter full scale that pushing syringe cylinder piston 3 needs to demarcate at injector syringe 4 one stroke of passing by, one optoelectronic switch 11 is arranged in the stroke, signal acquisition circuit 9 detects optoelectronic switch 11 in real time, when injector syringe piston 3 process optoelectronic switches, send a signal to CPU, to be the boundary, whole formation is divided into half way and following half way through optoelectronic switch 11; CPU is by calculating the displacement data of half way and following half way, and displacement data is recorded among the eeprom12.
Stationary installation 18 comprises pull bar 15 and groove 16, and two projectioies on the injector syringe are fixed in the groove 16, and to fix moving on the direction parallel with syringe, pull bar 15 has an open-ended annulus, is enclosed within on the syringe 3, with the fixedly swing of syringe.
The pull-up displacement of the pull bar 15 by stationary installation 18 detects syringe 4 nominal volume specifications, according to the displacement data of cylinder piston 3 and the nominal volume specification of syringe 4, obtain interior sectional area.
Stationary installation 18 also includes three optoelectronic switches 17, and three optoelectronic switch series arrangement are arranged on the stroke of pull bar, and first optoelectronic switch is 17a, and second optoelectronic switch is 17b, and the 3rd optoelectronic switch is 17c; The luminous arm of pull bar shading light electric switch 17 during by optoelectronic switch 17 and be subjected to the light arm triggers the variation of electric signal; Press 3 optoelectronic switches of external diameter scope packing of the syringe specification of each producer, can detect syringe nominal volume specification by optoelectronic switch like this.
The specific practice that detects the syringe specification is: the pull-up displacement with pull bar is a foundation, makes the external diameter scope of the syringe specification of syringe overall diameter to be marked and each producer do contrast, thereby judgement is contained in the syringe specification on the machine.
Be distributed with control knob, status indicator lamp and parameter on the control panel 7 and show charactron.Control knob is used for input control order and regulate various states, and status indicator lamp and parameter show that charactron shows various status informations and parameter information.
Walk once to form the displacement data that obtains half way and following half way on the cylinder piston by syringe, suppose that going up the half way displacement is a, the half way displacement is b up and down, and the displacement that obtains whole stroke is (a+b).By measuring the syringe needle specification is vml, obtains that sectional area is in the syringe: v/ (a+b) so just obtains two critical sizes of sectional area in scale length that micro-injection pump need mark with syringe and the syringe.
Because clinical practice need be in syringe before the medicine injection finishes, syringe needle is extracted in prompting in advance, and we have introduced the notion of remaining warning.The remaining warning promptly: the prompting nursing staff extracted syringe needle when the medicament residue in syringe was a certain amount of, this drug residue can be provided with by the user also can be by the residual quantity of a standard of procedure stipulation, and machine produces sound and light alarm when reaching the residual volume threshold values during actual injection.
Definite needs of residual quantity threshold values are known the volume dose of residue in the uncertain syringe, and our program is achieved in that so
If last half way displacement is a, following half way displacement is b, and the displacement that obtains whole stroke is (a+b).By measuring the syringe needle specification is vml, obtains the interior sectional area of syringe to be: v/ (a+b).If remaining x milliliter needs remaining the warning, our last half way displacement is a, and following half way displacement is: b.Can calculate this syringe x milliliter length and be ((a+b) x)/v, that injector syringe piston 3 triggers remaining the warning by after optoelectronic switch (11) [b-((a+b) x)/v] displacement.After injector syringe piston 3 passes through optoelectronic switch b distance, trigger and inject the warning that finishes.
The invention has the beneficial effects as follows: by using this labeling system and method, can measure the specifications parameter of any disposable syringe exactly, thereby make micro-injection pump be suitable for all on the market syringes.
