Summary of the invention
The utility model is in order to solve the above-mentioned technical problem, to provide one kind during washing pipe, can replace manual operation,
Patient pain caused by promoting the pulse frequency of salt water excessively high or excessive velocities because of medical staff is avoided, causes washing pipe to be not thorough slowly excessively
The mechanical pulsing formula medical fluid automatic feed device that phenomenon occurs.
The technical solution of the utility model is:
Mechanical pulsing formula medical fluid automatic feed device, including chamber cylinder, chamber cylinder front end are equipped with ozzle, insert push rod in chamber cylinder,
Piston is installed in push rod front end, is characterized in that and pedestal is set in chamber tube rear end, be equipped with pilot hole at pedestal axle center, push away
Rod rear end is drawn by the pilot hole of pedestal, pulse guide pad is circumferentially uniformly arranged in pedestal circumference inner wall, in push rod outer circumferential walls
It is circumferentially uniformly arranged axial pulse guide groove, 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 inflection point, prevents during washing pipe, because of bullet
Spring force, which gradually weakens, influences pulsatile effect.
Further preferably, pulse guide groove inner bottom surface is corrugated, further enhances pulsatile effect.
Further preferably, it is equipped with the first radial keyhole on the base, the second keyhole equipped with radial direction on push rod, first
It is installed with safety cock in keyhole and the second keyhole, when medical fluid being added into lumen, push rod is fixed.
Further preferably, be equipped with annular positioning groove in pedestal front end face, the chamber cylinder is inserted in locating slot, and pedestal with
It is installed with the positioning pin being arranged circumferentially between lumen, is dismounted convenient for lumen.
Further preferably, the slot being arranged circumferentially is equipped in pedestal circumference inner surface, the pulse guide pad is embedded in
In corresponding slot.
Further preferably, the pulse guide pad is spherical shape, is easily installed, pulse washing pipe effect is good.
The beneficial effects of the utility model are:
Due to being circumferentially uniformly arranged pulse guide pad in pedestal circumference inner wall, axis is circumferentially uniformly arranged in push rod outer circumferential walls
To corrugated pulse guide groove, each pulse guide pad in the corresponding pulse guide groove, and be located on push rod piston and
Spring is cased between pedestal.When washing pipe operates, push rod is pulled back first, and piston compressed spring is made to store power, it is filling using medical fluid
Medical fluid is filled into lumen through ozzle by machine, is then connected to lumen front end ozzle with perfusion tube, is pulled out safety cock, release spring bullet
Power, piston promote salt water in perfusion tube.Spring force discharge during, pulse guide pad in pulse guide groove from it is interior to
Outer movement, at each inflection point of corrugated pulse guide groove, pulse guide pad by the resistance at pulse guide groove inflection point because being advanced
Speed slows down, and the rate that changes the entire traveling process of pulse guide pad is advanced, and then makes piston with impulse form by salt water
It promotes in perfusion tube, completes pulse washing pipe, instead of traditional artificial operation, avoid because medical staff promotes the pulse frequency of salt water
Excessively high or excessive velocities cause patient pain, cause washing pipe to be not thorough phenomenon slowly excessively.
