Description
Technical field
The present invention relates to medicine equipment, more particularly to mechanical pulsing formula decoction automatic feed device.
Background technology
During medical treatment is had an intravenous drip, transfusion terminates or the medication interval time is longer, it is necessary to using decoction to transfusion twice
Pipe carries out washing pipe.Existing tube-washing method is will to be connected installed in medical fluid injector front end ozzle with woven hose, between medical personnel
Have a rest and promote medical fluid injector push rod, the decoction in medical fluid injector is pushed into woven hose with impulse form, makes decoction in woven hose
It is interior to form small whirlpool, the residual medicine in infusion pipeline is rinsed well.This tube-washing method fully relies on medical personnel's operation
Gimmick, because of individual difference, medical personnel promote the pulse frequency of salt solution too high or excessive velocities cause patient pain's phenomenon to occur.
The content of the invention
In order to solve the above-mentioned technical problem the present invention is, there is provided one kind can replace manual operation, avoid during washing pipe
Because medical personnel promote salt solution pulse frequency is too high or excessive velocities caused by patient pain, cause the not thorough phenomenon of washing pipe slowly excessively
The mechanical pulsing formula decoction automatic feed device of generation.
The present invention technical solution be：
Mechanical pulsing formula decoction automatic feed device, including chamber cylinder, chamber cylinder front end are provided with ozzle, push rod are inserted in chamber cylinder,
Piston is installed in push rod front end, it is characterized in that：Pedestal is set in chamber tube rear end, pilot hole is provided with pedestal axle center, pushes away
Rod rear end is drawn by the pilot hole of pedestal, pulse guide pad is circumferentially uniformly arranged in pedestal circumferential inner wall, in push rod outer circumferential walls
Axial pulse guide groove is circumferentially uniformly arranged, the pulse guide groove is corrugated, and each pulse guide pad is embedded in corresponding pulse
In guide groove, and spring is cased between piston and pedestal on push rod.
Further preferably, radian incrementally increases from the front to the back at pulse guide groove flex point, prevents during washing pipe, because of bullet
Spring force gradually weakens influence pulsatile effect.
Further preferably, pulse guide groove inner bottom surface is corrugated, further enhances pulsatile effect.
Further preferably, the first keyhole of radial direction is provided with pedestal, the second keyhole provided with radial direction on push rod, first
Safety cock is installed with keyhole and the second keyhole, when decoction is added into lumen, push rod is fixed.
Further preferably, be provided with annular positioning groove in pedestal front end face, the chamber cylinder is inserted in locating slot, and pedestal with
The alignment pin being arranged circumferentially is installed between lumen, is easy to lumen to dismount.
Further preferably, the slotted eye being arranged circumferentially is provided with pedestal circumferential inner surface, the pulse guide pad is embedded in
In corresponding slotted eye.
Further preferably, the pulse guide pad is spherical to be easily installed, pulse washing pipe effect is good.
The beneficial effects of the invention are as follows：
Due to being circumferentially uniformly arranged pulse guide pad in pedestal circumferential inner wall, axle is circumferentially uniformly arranged in push rod outer circumferential walls
To corrugated pulse guide groove, each pulse guide pad is embedded in corresponding pulse guide groove, and on push rod positioned at piston and
Spring is cased between pedestal.When washing pipe operates, push rod is pulled back first, piston compression spring is stored power, it is filling using decoction
Decoction is filled into lumen by machine through ozzle, and then lumen front end ozzle is connected with woven hose, pulls out safety cock, release spring bullet
Power, piston promote salt solution in woven hose.Spring force discharge during, pulse guide pad in pulse guide groove from it is interior to
Outer motion, at each flex point of corrugated pulse guide groove, pulse guide pad by the resistance at pulse guide groove flex point because being advanced
Speed slows down, and the speed that changes the whole traveling process of pulse guide pad is advanced, and then makes piston with impulse form by salt solution
Promote in woven hose, complete pulse washing pipe, operated instead of Traditional Man, avoid because medical personnel promote the pulse frequency of salt solution
Too high or excessive velocities cause patient pain, cause the not thorough phenomenon of washing pipe to occur slowly excessively.
