In above-mentioned threeway liquid medicine filter, each support portion sheet triangular in shape, and each support portion is perpendicular It is directly built up on the guide surface.
In above-mentioned threeway liquid medicine filter, the shell includes the upper casing and lower casing being mutually inserted, the medical fluid mistake Filter membrane is crimped between upper casing and lower casing in the edge of disc-shaped and liquid medicine filtering membrane.
In above-mentioned threeway liquid medicine filter, the injection member is in tubbiness, and the inside of closing one end has protrusion Closure part, the closure part are caught in the outer end of the chemical feed pipe and are interference fitted with the chemical feed pipe.
As another situation, in above-mentioned threeway liquid medicine filter, in the form of sheets, the injection member is set the injection member It is placed on the inside of chemical feed pipe outer end and passes through heat seal or be weldingly fixed on chemical feed pipe outer end.
In above-mentioned threeway liquid medicine filter, have on the outside of the liquid feeding end for the circular cone be bonded with infusion pipeline Face, the outlet end outside have cone joint.
In above-mentioned threeway liquid medicine filter, the lateral wall of the liquid feeding end has the annular shoulder block and the shoulder block of protrusion Position be higher than junction between the chemical feed pipe and liquid feeding end.
In above-mentioned threeway liquid medicine filter, between the injection member and the chemical feed pipe by heat seal, welding or The mode of bonding is mutually fixed.
In above-mentioned threeway liquid medicine filter, the chemical feed pipe is obliquely installed, and the outer end position of the chemical feed pipe is higher than Inner end positions, and the outer end of chemical feed pipe than inner end further from the axis of the liquid feeding end.
Compared with prior art, chemical feed pipe is arranged in liquid feeding end side in this threeway liquid medicine filter, because of threeway medical filtration Device is closer apart from transfusion needle in infusion apparatus, and transfusion needle can be directly over after dosing and is sent into human body, is no longer needed to by other portions Part, faster, drug delivery is high-efficient for drug delivery speed.
