The automatic import system of medicine with electricity irritation function
Technical field
The invention belongs to medical Instrument field, relate to a kind of automatic import system of medicine with electricity irritation function.
Background technology
For a long time, the mode of prevention and treatment disease has a variety of, such as oral drugs, intravenous injection, intramuscular injection etc.In case mode is selected, receptor depends on physics and chemical factor with receptor self to a great extent to the absorption of medicine and curative effect.Studies show that in recent years, the live body electroporation technology utilizes electric impulse signal to change membrane passage, thereby make things convenient for medicine to enter the raising receptor of very big degree in the cell tissue to the absorbance of medicine, this technology is used widely at medical domain, and occur a lot on the market medicine take this technology as the basis imports instrument thereupon.This quasi-instrument utilizes the stimulating electrical signal destination organization, thereby the absorption efficiencies of macromole in histiocyte such as raising dna vaccination have good clinical effectiveness, are used widely.
On the other hand, traditional injection system also faces the challenge.Progress along with science and technology, the drug injection instrument is towards the future development of automatization, precise treatment, occurred a lot of automatic injection instruments, automatic injection pump, precision syringe etc. on the market, the appearance of this quasi-instrument has improved the automatization of drug injection, has also improved the precision of little metered shot.
But in actual applications, drug injection and electricity irritation generally are proceed step by step, receptor is after specific destination organization place accepts drug injection (being generally traditional intramuscular injection), operator adopt medicine importing instrument that this destination organization is carried out stimulating electrical signal, accelerate histiocyte to the absorption of medicine.Because step by step, a minute instrument carries out, this kind mode cause injecting with electricity irritation in the middle of interval larger, affect the effect that medicine imports, this mode of while operates more loaded down with trivial details, automaticity is low.
Therefore, a kind of gather automatic injection and electricity irritation in the medicine import system of one by urgent needs.

Embodiment three:
Referring to accompanying drawing 1, originally have the medicine automatic injection import system of electricity irritation function mainly by micro-automated injection device 100, electrical stimulation device 200, control station 300, injection device 400, hand-held housing 500 forms.Automated injection device 100, electrical stimulation device 200, injection device 400 is encapsulated in the hand-held housing 500.Housing 500 is divided into placket 501, back seat 502 and end cap 503, and placket 501 is connected with 502 by helicitic texture 505, by rotating separating and being connected of realization placket 501 and back seat 502.Be fixed with motor 101 in the back seat 502 and be connected with screw mandrel 103 by bevel gear 102, realize automatic injection but be connected with slide block 104 pushing syringe piston rods 402 on the screw mandrel 103.Slide block 104 is provided with pressure transducer 106 with piston rod 406 contact positions, is provided with limit switch 105 on the back seat 101.Placket 501 front ends have Baltimore groove, and the top of Baltimore groove has through hole, and groove shapes matches with the syringe front end, are used for fixedly syringe.The rear end of placket 501 has circular hole, and syringe cylinder 401 can insert in the placket 501 by circular hole, and syringe needle 403 stretches out by through hole, and length is about 13mm.
501 of end cap 503 and plackets are provided with slideway and step 506, end cap 503 stressed can moving along slideway, and 506 places stop to step.End cap 503 is provided with spring 504, the power that available buffer is suffered with the front end of placket 501.Placket 501 is embedded with two electrode needle 201, described electrode needle is acupuncture needle, two pin spacings are 10mm, electrode needle one end exceeds barrel front end 13mm, consistent with syringe needle, the other end gos deep into back seat 502 and contact with the sheet metal 202 of conduction along placket, is provided with on the sheet metal 202 and embeds mouth, be enlarge active surface, but this end face overstriking of electrode needle.
The connection wire 203 of electrode needle, the control circuit of motor and power circuit link to each other with control station 300, are packaged with the controller of realizing automatic injection and electricity irritation in the control station 300, and the surface is provided with display screen 301 and keyboard 302.
Take off placket 501 from back seat 502, with the injection device 400 that medicine the is housed placket 501 of packing into, the placket choosing that injection device will be housed screws in back seat, and at this moment, electrode needle 201 contacts with conductive metal sheet 202, and spring 503 is in relaxed state.With outer end cap 503 contact receptors, press the on ﹠ off switch on the control station, select motor parameter, electrical stimulation pattern and electric impulse signal parameter and stimulation time.With drive end bearing bracket 503 contact receptors, and vertically firmly electrode needle and syringe needle are inserted receptor.Press automatic injection and trigger key, motor 101 rotates, drive slide block 104, when 104 touch piston rod 402, pressure transducer 106 beginning acknowledge(ment) signals, by the time drug injection finishes, piston rod 402 is subject to the resistance from the syringe cylinder front end, the pressure that pressure transducer 106 detects increases, and reaches thresholding, and signal feedback is to single-chip microcomputer, 101 stop motions of control step motor, trigger simultaneously electric-stimulation controller, the electric impulse signal of generation imports recipient cell into by electrode needle 201, carries out electricity irritation.Electricity irritation stops oppositely pin being extracted receptor afterwards, press simultaneously the motor reset key according to before the displacement walked, oppositely slide block is attributed to raw bits, use convenient next time.Take off placket 501, injection device 200 is taken off, the placket of sky is loaded onto, use convenient next time.When pressure transducer 106 lost efficacy, piston rod 106 went beyond the limit of the position under the driving of motor, touch limit switch 105, the motor stop motion, thus play the effect of overload protection.
Fig. 3 has showed the motor process that syringe needle inserts receptor and extracts end cap and spring in the placket of receptor.
The description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention.
