The specific embodiment
Describe this utility model in detail below in conjunction with accompanying drawing, it is more obvious that the purpose of this utility model and effect will become.
With reference to accompanying drawing 1, this utility model comprises based on the injecting liquid drug apparatus of linear electric motors and solenoid-driven: housing 1, electric magnet 2, permanent magnet 3, slip lid frame 4, medicine storing pot 5, linear motor coil cabin 7, limiting lock 11, limiting plate 12, drain syringe needle 13, infusion set 14 and watchband 16.
Electric magnet 2 is fixed on housing 1 an inner side, and permanent magnet 3 places in the cavity of electric magnet 2, and the opposite side of housing 1 inside is instrument room 15; Linear motor coil cabin 7 is fixed in the housing 1, and contact with electric magnet 2, medicine storing pot 5 places in the linear motor coil cabin 7, and spacing by limiting lock 11, limiting plate 12 is fixed in the housing 1, drain syringe needle 13 1 ends pass limiting plate 12, and the other end links to each other with infusion set 14, and watchband 16 is fixed on housing 1 outer infusion set 14 places.
As shown in Figure 2,5 two end faces of medicine storing pot are pasted respectively the first film 8 and the second thin film 9, have piston 6 in it.
As shown in Figure 3, infusion set 14 comprises: drain rubber 17, infusion needle 18, the first metal clips 19, the second metal clips 20, the 3rd metal clips 21 and infusion set housing 22.
Connect design according to said apparatus, device will have following functions:
After electric magnet 2 energising, because repulsion, permanent magnet 3 can skid off in electric magnet 2, and with piston 6 combinations.Pushing slip lid open, is drug storage cabin 10, and medicine storing pot 5 is placed in the drug storage cabin 10.Medicine storing pot 5 can be changed as required.
10 belows, drug storage cabin are linear motor coil cabins 7, are equipped with the primary coil of linear electric motors.Phase sequence according to energising is different, and permanent magnet 3 can forward and reversely move, and realizes transfusion thereby drive piston 6.Limiting lock 11 is for medicine storing pot 5 being blocked, keeping fixing.When medicine storing pot 5 travels forward, can push limiting lock 11 open.Medicine storing pot right side thin film 9 can be punctured by drain syringe needle 13 when medicine storing pot 5 travels forward, and medicine storing pot 5 can stop at limiting plate 12 places, and medicinal liquid is exported by the propelling of piston 6.Drain syringe needle 13 can freely take out replacing by opening to renovate, and drain syringe needle 13 and limiting plate 12 are fixed by draw-in groove.
Infusion set 14 is main devices that human body is infused.Infusion set 14 is comprised of drain rubber 17, infusion needle 18, the first metal clips 19, the second metal clips 20, the 3rd metal clips 21, cavity 22.Drain rubber 17 also is used for infusion needle 18 is realized sealing except the circulation medicinal liquid, guarantees the health of medicinal liquid free air space.The first metal clips 19, the second metal clips 20 are used for air-out by the solenoid control adhesive, the first metal clips 19, the second metal clips 20, the 3rd metal clips 21 are used for infusion needle 18 is thrust the human muscle by the solenoid control adhesive, realize transfusion.
The job step of device is as follows:
1, changes medicine.Open slip lid, medicine storing pot 5 is taken out from drug storage cabin 10, cleaning and sterilizing piston 6 and medicine storing pot 5, isolation rubber or the thin film of replacing medicine storing pot 5 both sides are put into medicine storing pot 5 good seals with medicine.
2, change syringe needle.Drain syringe needle 13 is taken off from limiting plate 12, change.Infusion set 14 can take out, and cleans.After the cleaning, reinstall.
3, put into medicine storing pot 5, shut slip lid, wait for.
4, receive the signal (such as pulse, heart beating etc.) of patient's crisis of sending when bluetooth, controller will be to electric magnet 2 energisings, and electric magnet 2 flicks permanent magnet 3 owing to repulsion.Permanent magnet 3 breaks through medicine storing pot left side thin film 8, combines closely electric magnet 2 outages with piston 6.
5, at this moment, controller T1 intervalometer begins timing, the primary coil that is laid on the linear electric motors of injection device bottom begins energising, permanent magnet 3 drives piston 6 and medicine storing pot 5 promotes forward, drain syringe needle 13 punctures medicine storing pot 5 right side thin film 9, and medicinal liquid flows into syringe needle, and medicine storing pot 5 integral body stop at limiting plate 12 places, piston 6 setting in motions, the timing of T1 intervalometer finishes.
The movement velocity of supposing piston 6 is v, and the distance of medicine storing pot 5 original position and limiting plate 12 is s, time t1=s/v of 12 from the initial position to the limiting plate so, and t1 is the timing parameter of intervalometer T1.
6, the timing of T1 intervalometer finishes in the controller, and the T2 intervalometer begins timing, and start electromagnetic valve this moment, makes the first metal clips 19 and 20 adhesives of the second metal clips.The medicinal liquid that flows into drain syringe needle 13 begins air-discharging in cavity 22.
According to processing technology, can obtain the volume V of required air-out
1(volume that comprises the upper surface of drain syringe needle 13, infusion needle 18, the second metal clips 20 and infusion set 14).Here leave surplus, namely the edge volume of the first metal clips 19 and drain rubber 17 is counted.Can know the area of section S of medicine storing pot 5.Can get thus piston 6 advance distance L=V
1/ S, time t2=L/v.T2 is the timing parameter of intervalometer T2.
7, the timing of T2 intervalometer finishes in the controller, and the T3 intervalometer begins timing, makes electromagnetic valve the first metal clips 19, the second metal clips 20,21 adhesives of the 3rd metal clips, and infusion needle 18 inserts muscle, begins transfusion.
The medicine liquid volume of medicine storing pot 5 is V as can be known
0, emptying volume required be V
1Because piston 6 in order not touch drain syringe needle 13, need to stop linear electric motors, also stop motion of piston 6 after being advanced to a certain degree.This distance can be set as required need to leave surplus equally for l(), then be input to the medicine liquid volume V=V in the human body
0-V
1-S*l.T3=V/S/v then.Because piston 6 stops and needs certain hour, so t3=t3-T.(T can set according to practical situation).T3 is the timing parameter of intervalometer T3.
The timing of T3 intervalometer finishes in the controller, shut electromagnetic valve, so that metal clips separates, infusion needle 18 is withdrawn from.Stop to linear electric motors energising, stopping infusion.
