Description
Technical field
The utility model is related to a kind of medical instrument more particularly to a kind of syringes for infusion pump.
Background technology
In clinical position, many drug therapies needs of patient are very accurate, so that needing to use infusion pump to be transfused medicine
Object.By in syringe clamping to infusion pump come implement be transfused drug.Existing syringe as shown in figure 9, including cylinder 10,
Piston rod 20, piston head 21, piston handle 22, nipple 30, protrusion 40.The catching parts of infusion pump are resisted against the prominent of syringe
The left side in the portion of rising, propulsive element are resisted against the right side of piston handle, thus apply thrust to piston to piston, by the medicine in cylinder
Object is released via nipple.In practical work, since each producer of the stroke of infusion pump is not quite similar, on a kind of infusion pump
It can realize complete infusion, when changing another infusion pump, the stroke for being advanced to infusion pump terminates completely out drug not yet, also
It is to say stroke alarm occurred and the drug in syringe tube also has residue at this time.If the drug renewed, by remaining medicine
Object is thrown away, and unnecessary waste will be caused to patient.
Utility model content
In view of the above problems, the utility model is directed to a kind of syringe for infusion pump, can adapt to difference
The stroke offering question of the infusion pump of species ensures that whole drugs are transfused.
It includes injection tube and piston rod to the syringe for infusion pump of the utility model, and the first end of injection tube is formed
There is nipple, protrusion is formed on the outside of the second end of injection tube；The first end of piston rod includes piston head, and piston head is slideably
It is inserted in injection tube；The second end of piston rod is provided with multiple first through hole；It is further provided in the second end of piston rod
End cap；End cap is formed as cylinder, the first end opening of end cap, and the second end of end cap is connected with the handle of plate；The of piston rod
Two ends are inserted in from the first end of end cap in end cap；The first end of end cap is formed with the second through hole；Further comprise on piston rod
The pin removably set；Pin is optionally inserted into one in the multiple first through hole and the second through hole, with
Piston rod and end cap are fixed together；The holding section of infusion pump is resisted against protrusion towards on the side of nipple one side；Infusion
The promotion part of pump is resisted against on the side of separate nipple one side of the handle of end cap.
Preferably, the multiple first through hole is set at equal intervals.
Preferably, the adjacent first through hole is perpendicular to one another.
The syringe for infusion pump of the utility model, by setting multiple through holes on the piston rod, adjustment end cap exists
Thus the binding site of piston rod changes the whole length after entire piston rod installation end cap；For different infusion pumps, for
End cap position is adjusted to property, thus matches infusion pump so that the drug in injection tube can be released from nipple completely.

Specific embodiment
In the following, the utility model is described in detail with reference to Figure of description 1-9.
The syringe for infusion pump of the utility model it include injection tube 10 and piston rod 20.
The first end of injection tube 10 is formed with nipple 30, and protrusion 40 is formed on the outside of the second end of injection tube 10.
The first end of piston rod 20 includes 21, piston, and piston head 21 is slidably inserted into injection tube 10.Piston rod
20 second end is provided with multiple first through hole 23.
End cap 24 is further provided in the second end of piston rod 20.End cap 24 is formed as cylinder, i.e., middle part includes hollow
Portion 25.First end opening of end cap 24, the second end of end cap 24 are connected with the handle 22 of plate.
The first end of the second end of piston rod 20 from end cap 24 is inserted in end cap 24, and furnace body is in insertion hollow bulb 25.
Further comprise the pin removably set on piston rod 20；Pin is optionally inserted into one in multiple first through hole 23
In a and the second through hole 26, piston rod 20 and end cap 24 are fixed together.
The holding section of infusion pump is resisted against protrusion 40 towards on the side of 30 one side of nipple；The promotion part of infusion pump against
On the side of 30 one side of separate nipple of the handle 22 of end cap 24.
Multiple first through hole 23 can be set at equal intervals.Adjacent first through hole 23 can be perpendicular to one another, with maximum
Ensure to degree the intensity of the first end of piston rod.
Drug is drawn into injection tube 10, then according to the situation of infusion pump, by being selected from multiple first through hole
One first through hole 23 is fixed together after being matched with the second through hole 24 with pin, thus adjusts end cap 24 compared with piston rod 20
Outwardly extending length, after ensureing that infusion of drug is complete, the stroke of infusion pump is also not to the end.Injection tube is held on infusion pump
Afterwards, the one side of protrusion 40 is resisted against the holding section of infusion pump, and the second side of handle 22 is resisted against on the promotion part of infusion pump, by
This, under the propulsion of infusion pump, drug is flowed out from the nipple 30 of syringe, and trouble is entered via the conduit being connected with nipple 30
In person's body.
