Piston is fixed on piston rod top, and the through-hole for unicom needle holder and syringe is additionally provided on back taper abradant surface two.
Preferably, it is provided with knurled pattern on the conical abradant surface one and/or back taper abradant surface two.
Preferably, the piston rod top is provided with cross card slot, is provided on the piston and cross card slot shape
The cross protrusion of shape complementation, the cross protrusion can be stuck in cross card slot.
Preferably, the tail end of the piston rod is fixedly installed "-" type or criss-cross handle.
Preferably, it is provided with anti-skid chequer on the syringe lateral wall.
Preferably, it is also equipped with nipple cap in the needle holder.
Preferably, dispensing hole is provided in the barrel sidewall.
Preferably, the central axis of the needle holder and the central axis of syringe are misaligned.
The utility model has the advantages that：（1）Make grinding and injection process simplification, improves operational efficiency；（2）It is closed to grind
Mill reduces drug waste；（3）Medicament grinder rubbing surface keeps drug granule uniformly tiny, is conducive to injection stomach tube；（4）One people one
Pipe reduces cross contamination；（5）Material is light, reduces nursing staff's workload；（6）Cost is not high, economical and practical.

Specific implementation mode
Embodiment one
As shown in Figure 1, the nasal feeding patient oral medicine grinding syringe includes syringe 1, the needle holder positioned at 1 top of syringe
6, the top surface of the piston rod 2 in syringe 1 and the piston 4 positioned at 2 top of piston rod, the piston is conical abradant surface
One 7, syringe inner wall top surface is back taper abradant surface 25, the cone abradant surface 1 and 25 shape of back taper abradant surface
Shape matches, and the cone abradant surface 1 and back taper abradant surface 25 are worked in coordination for grinding, and piston is fixed on piston
2 top of bar.
Preferably, it is provided with knurled pattern on conical abradant surface 1 and/or back taper abradant surface 25.It is conical opposite
In cylinder, the abradant surface with bigger improves grinding efficiency, in addition, medicinal powder is also easier to gather the cone tip part of circular cone.
The syringe of prestige height production at present, when piston rod 2 rotates, the piston friction face on 2 top of piston rod does not turn, therefore,
In order to enable piston with 2 turns of piston rod, need to be transformed such syringe, specifically, such as Fig. 2,2 top of piston rod
It is provided with cross card slot, is provided on the piston and the cross of cross card slot shape complementation protrusion, the cross
Protrusion can be stuck in cross card slot, to make piston be fixed on 2 top of piston rod, when rotary-piston bar 2 is ground, piston
Also it is rotated with piston rod 2, and piston can be rotated and reverse with piston rod 2.
It is additionally provided with the through-hole for unicom needle holder 6 and syringe 1 on back taper abradant surface 25, is convenient for syringe needle extract
Body dissolves drug, then by injecting liquid drug to nasogastric tube, does not have through-hole on conical abradant surface 1.Preferably, in needle holder
The central axis of mandrel line and syringe is misaligned, identical with aperture with the high syringe position of current prestige, can avoid drug in this way
Powder is gathered in cone bottom and results in blockage through-hole.
Preferably, for labour-saving rotary-piston bar 2, palm is uncomfortable when hand-held piston rod 2 being avoided to rotate, by piston shaft
Exposed parts lengthen 2cm, and the tail end of piston rod 2 is fixedly installed "-" type or criss-cross handle 9 or similar open bores device
Handle 9 is easy to hold and rotate.
Preferably, in order to increase the frictional force between hand and syringe 1, anti-skid chequer is provided on 1 lateral wall of syringe.
Preferably, the pintle and syringe needle for cancelling current nasal feeding cartridge syringe, to economize on resources instead nipple
Cap 8 is mounted in needle holder 6, in case drug powder overflows.
Dispensing hole 3 is provided on 1 side wall of the syringe at the tail portion of syringe 1, dispensing 3 position of hole should avoid scale
Line.When not having dispensing hole, piston rod is extracted, is offerd medicine from syringe tail portion.
The application method of the present embodiment is as follows：Nipple cap 8 is opened, piston rod 2 is pulled outwardly, dispensing hole 3 is made to be located at piston
Front, from dispensing hole 3 put into oral medicine；Piston rod 2 is pushed ahead, conical abradant surface 1 and back taper abradant surface 25 are made
It is close, nipple cap 8 is covered, rotary-piston bar 2, by oral medicine grind into powder, closed grinding reduces drug waste；It extracts
Pure water makes medicine powder be dissolved in water, and injects in nasogastric tube.The utility model makes grinding and injection process simplification, improves
Operational efficiency.Medicament grinder rubbing surface keeps drug granule uniformly tiny, is conducive to injection stomach tube；One people one manages, and reduces and intersects dirt
Dye；Material is light, reduces nursing staff's workload；Cost is not high, economical and practical.
