Liquid food flows into valve 16 and closes when 17 opening, and the two alternate run conveys liquid food into nasogastric tube.
When 19 clamping slider 4 of syringe piston clamping device moves to most preceding, the line of rabbet joint and syringe of lower clamping device 7
The minimum distance of the distance of piston clamping device 19, that is, the line of rabbet joint and syringe piston clamping device 19 that descend clamping device 7 is denoted as
L1；When the piston of liquid food syringe 14 is fully advanced, alar part is at a distance from piston tail, i.e. syringe alar part and tail portion
Minimum distance is denoted as L2.This liquid food syringe Electric assist device may be only available for the liquid food syringe that L2 is less than or equal to L1,
Liquid food syringe for L2 greater than L1 can not be applicable in.
The piston of liquid food syringe 14 is slightly extracted, so that the distance of syringe alar part and piston tail is equal to lower folder
The line of rabbet joint of mechanism 7 and the distance of syringe piston clamping device 19 are held, so that the piston tail of liquid food syringe 14 is clipped in injection
On device piston clamping device 19.Manual lead screw 28 is adjusted, front limit mechanism 29 is adjusted at a distance from lower clamp system 7, to adapt to
The syringe of different length.Means of communication 15 has a conical surface interface, and the delivery outlet of liquid food syringe 14 is inserted into the conical surface and connects
After mouthful, entire liquid food syringe 14 is placed between lower clamp system 7 and upper clamping mechanism 8, the alar part of liquid food syringe 14 is inserted
In the line of rabbet joint of lower clamp system 7, upper clamping mechanism 8 is covered.Screwing bolts 1 and bolt 2 27 are so that liquid food syringe 14
It is fixed.Screwing bolts 4 41 are so that relatively fixed between means of communication 15 and liquid food syringe 14.
It connects with the mains, operation control button 32 allows machine to enter injection state, and sliding block 4 drives syringe piston to carry out at this time
It moves back and forth.When sliding block 4 pulls back piston, liquid food, which flows out valve 17, is closed, and liquid food flows into valve 16 and opens, i.e. rigid body
It is separated between one 21 and rigid body 2 22, gap is larger, and liquid food inflow pipe 9 is put between rigid body 1 and rigid body 2 22 at this time.
When sliding block pushes piston forward, liquid food flows into valve 16 and closes, and liquid food outflow valve 17 is opened, i.e. rigid body 3 23 and rigid body
It is separated between 4 24, gap is larger, and liquid food effuser 10 is put between rigid body 3 23 and rigid body 4 24 at this time.Then bullet is covered
Property pipeline limiting device 25 eaten to prevent fluid stopping and flow into the position of pipe 9 and liquid food effuser 10 accidental change occurs.Liquid food is flowed into
Pipe 9, which leads to, fills the container of warm water, sucking discharge warm water, with the air in emptying system, allows machine break-off later,
Stomach tube connector 11 is inserted into stomach tube 12, screwing bolts 3 38 complete installation so that the two is fixed above.
Liquid food is flowed into pipe 9 towards the container for filling liquid food, operation control button 32 allows machine to enter injection state.Control
System 18 closes liquid food and flows out valve 17, opens liquid food and flows into valve 16, and controls motor 1 and drive screw rod 2 that sliding block 4 is promoted to carry
Syringe piston clamping device 19 pulls back the piston of liquid food syringe 14 along guide rail 3, so that liquid food is inhaled into liquid food note
Emitter 14.Liquid food is closed at this time and flows into valve 16, is opened liquid food and is flowed out valve 17, sliding block 4 pushes forward liquid food syringe 14
Piston, so that liquid food is injected into stomach tube 12 by liquid food effuser 10.
Lead to the container for filling clear water when liquid food flows into pipe 9, and stomach tube connector 11 does not connect stomach tube 12, and leads to dirt
When water reception device such as pond, the process of aforementioned sucking, injection is repeated several times, clear water can be sucked and be then exhausted from, to can realize
Pipe 9, liquid food effuser 10, the cleaning function of means of communication 15 and liquid food syringe 14 are flowed into liquid food.
Pressure sensor 30 stops working when resistance is greater than setting threshold values for detecting propelling resistance, prevents resistance big
Cause the excessive pipe explosion of nasal feeding overpressure.Temperature sensor 31 is for detecting motor temperature, when temperature is higher than setting threshold values
When stop working.The equipment such as charger baby of USB power source output interface is had when USB is used to have a power failure for arrangements of electric connection 34 by other
Product or laptop etc. power to this equipment.
Embodiment 2:
The present embodiment rest part is the same as example 1, and difference is only that,
First, means of communication 15 is connected through a screw thread with liquid food syringe 14, the part part such as Fig. 7.
Second, liquid food flows into valve 16 and liquid food outflow valve 17 is driven by decelerating motor.Valve is flowed into about liquid food
The local detail of door 16 is shown in Fig. 8.Decelerating motor 48 drives cam 49 to rotate, and when cam 49 presses to rigid body 2 22, rigid body 2 22 encloses
To press to fixed rigid body 1, folder closes the liquid food between rigid body 1 and rigid body 2 22 and flows into pipe for 44 rotations around the shaft
9, liquid food flows into valve 16 and closes, and 2 22 lower section of rigid body stops when triggering travel switch 1.When cam 49 turns to another side,
Tension spring 45 will promote rigid body 2 22 far from rigid body 1, unfold so that liquid food flows into pipe 9, liquid food flows into valve 16 and opens.
Stop when 2 22 lower section triggering travel switch 2 47 of rigid body.
The working principle and liquid food inflow valve 16 of liquid food outflow valve 17 are identical, and only the either on or off time is different,
It repeats no more.
Embodiment 3:
As shown in figure 9, the present embodiment rest part is the same as example 1, difference is only that, means of communication 15 and liquid food
Syringe 14 holds together, and the syringe in embodiment before is universal syringe, and the syringe of the one is
Dedicated custom syringe, body length are not necessarily to it is known that therefore front limit mechanism 29 is fixed relative to the distance of lower clamp system 7
Manual lead screw 28 is set, without setting retention mechanism 2 20, simplifies whole structure.
Embodiment 4:
As shown in Figure 10, the present embodiment rest part is the same as example 1, and difference is only that, retention mechanism 1 and tight
Gu mechanism 2 20 is band.
Using liquid food syringe Electric assist device of the invention, have structure simple, easy to use laborsaving, vulnerable part is more
It changes conveniently, can continuously inject, and connect reliably with stomach tube, be not susceptible to the advantages of isolating and falling off.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, in specific embodiments and applications can be with many changes may be made, as long as these variations are without departing from structure of the invention
Think, all belongs to the scope of protection of the present invention.
