Detailed description of the invention
Describe the present invention in detail below in conjunction with accompanying drawing, object of the present invention and effect will become more obvious.
With reference to accompanying drawing 1, the injecting liquid drug apparatus that the present invention is based on linear electric motors and solenoid-driven comprises: 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 the inner side of housing 1, and permanent magnet 3 is placed 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 housing 1, and contact with electric magnet 2, medicine storing pot 5 is placed in linear motor coil cabin 7, and it is spacing by limiting lock 11, limiting plate 12 is fixed in housing 1, drain syringe needle 13 one end is through limiting plate 12, and the other end is connected with infusion set 14, and watchband 16 is fixed on housing 1 outer infusion set 14 place.
As shown in Figure 2, medicine storing pot 5 two end faces paste the first film 8 and the second thin film 9 respectively, have piston 6 in it.
As shown in Figure 3, infusion set 14 comprises: drain rubber 17, infusion needle 18, first metal clips 19, second metal clips 20, the 3rd metal clips 21 and infusion set housing 22.
Drain rubber 17 is fixed on infusion set housing 22 inner tip, and its both sides all have hole for tapping; Infusion needle 18 and the first metal clips 19 are fixed as one, and the afterbody of infusion needle 18 is close to drain rubber 17, and the other end is successively through the hole in the middle of the second shell fragment 20 and the 3rd shell fragment 21; First shell fragment 19, second shell fragment 20 is connected respectively with the two ends of the 3rd shell fragment 21; By diaphragm seal bottom infusion set housing 22.
Connect design according to said apparatus, device will have following functions:
After electric magnet 2 is energized, due to repulsion, permanent magnet 3 can skid off in electric magnet 2, and is combined with piston 6.Push slip lid 23 open, be drug storage cabin 10, medicine storing pot 5 is placed in drug storage cabin 10.Medicine storing pot 5 can be changed as required.
Be linear motor coil cabin 7 below drug storage cabin 10, be equipped with the primary coil of linear electric motors.Different according to the phase sequence of energising, permanent magnet 3 can forward and reversely move, thus drives piston 6 to realize transfusion.Limiting lock 11 is to be blocked by medicine storing pot 5, keeps fixing.When medicine storing pot 5 travels forward, limiting lock 11 can be pushed open.On the right side of medicine storing pot, 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 place, and medicinal liquid is exported by the propelling of piston 6.Drain syringe needle 13 can be renovated 24 and freely takes out replacing by opening, and drain syringe needle 13 and limiting plate 12 are fixed by draw-in groove.
Infusion set 14 is the main devices of infusing to human body.Infusion set 14 is made up of drain rubber 17, infusion needle 18, first metal clips 19, second metal clips 20, the 3rd metal clips 21, cavity 22.Drain rubber 17, except circulation medicinal liquid, also for realizing sealing to infusion needle 18, ensures the health in liquid medicine flow space.First metal clips 19, second metal clips 20 is used for air-out by solenoid control adhesive, first metal clips 19, second metal clips 20, the 3rd metal clips 21 are used for infusion needle 18 to thrust human muscle by solenoid control adhesive, realize transfusion.
Cavity 22 depositing for air-out.At the instrument room 15 that the opposite side of device case 1 is control assembly, be placed with bluetooth, controller, battery etc.Battery is changed by battery hatch door 25.Watchband 16 for wearable device on arm.
The job step of device is as follows:
1, medicine is changed.Open slip lid 23, medicine storing pot 5 is taken out from drug storage cabin 10, cleaning and sterilizing piston 6 and medicine storing pot 5, change isolation rubber or the thin film of medicine storing pot 5 both sides, medicine is put into medicine storing pot 5 good seal.
2, syringe needle is changed.Drain syringe needle 13 is taken off from limiting plate 12, changes.Infusion set 14 can take out, cleaning.After cleaning, reinstall.
3, put into medicine storing pot 5, shut slip lid 23, wait for.
4, when Bluetooth receptions is to the signal (such as pulse, heart beating etc.) of patient's crisis of sending, controller will be energized to electric magnet 2, and permanent magnet 3, due to repulsion, flicks by electric magnet 2.Permanent magnet 3 breaks through thin film 8 on the left of medicine storing pot, combines closely with piston 6, electric magnet 2 power-off.
5, now, controller T1 intervalometer starts timing, the primary coil being laid on the linear electric motors bottom injection device starts energising, permanent magnet 3 drives piston 6 and medicine storing pot 5 to promote forward, drain syringe needle 13 punctures thin film 9 on the right side of medicine storing pot 5, and medicinal liquid flows into syringe needle, and medicine storing pot 5 entirety stops at limiting plate 12 place, piston 6 setting in motion, the timing of T1 intervalometer terminates.
Suppose that the movement velocity of piston 6 is v, the distance of medicine storing pot 5 original position and limiting plate 12 is s, so from initial position to limiting plate 12 time t1=s/v, t1 is the timing parameter of intervalometer T1.
6, in controller, the timing of T1 intervalometer terminates, and T2 intervalometer starts timing, now starts electromagnetic valve, makes the first metal clips 19 and the second metal clips 20 adhesive.The medicinal liquid flowing into drain syringe needle 13 starts air-discharging in cavity 22.
According to processing technology, the volume V of required air-out can be obtained
1(comprising the volume of the upper surface of drain syringe needle 13, infusion needle 18, 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.The area of section S of medicine storing pot 5 can be known.Piston 6 advance distance L=V can be obtained thus
1/ S, time t2=L/v.T2 is the timing parameter of intervalometer T2.
7, in controller, the timing of T2 intervalometer terminates, and T3 intervalometer starts timing, and make electromagnetic valve first metal clips 19, second metal clips 20, the 3rd metal clips 21 adhesive, infusion needle 18 inserts muscle, starts transfusion.
The medicine liquid volume of known medicine storing pot 5 is V
0, emptying volume required be V
1.After piston 6 is advanced to a certain degree, in order to not touch drain syringe needle 13, need to stop linear electric motors, piston 6 also stop motion.This distance can be arranged as required need equally to leave surplus for l(), be then input to the medicine liquid volume V=V in human body
0-V
1-S*l.Then t3=V/S/v.Certain hour is needed because piston 6 stops, therefore t3=t3-T.(T can set according to practical situation).T3 is the timing parameter of intervalometer T3.
In controller, the timing of T3 intervalometer terminates, and shut electromagnetic valve, makes metal clips be separated, and infusion needle 18 is withdrawn from.Stop to linear electric motors energising, stopping infusion.
