Description

Whole dosage drug-supply device for cavity and canal

This utility model relates to a kind of tract full dose administrator, can be with fluid or semifluid etc. to rectum or several noresidues of other tracts ground full dose administration with it.

Rectally is one of main route of administration of Drug therapy, is characterized in that absorption is fast, bioavailability is high, is subjected to liver little by function influence first.Existing rectally dosage form mainly contains suppository and enema etc., and the former easily pollutes finger, and the latter need adopt medication inconveniences such as special utensil in hospital, not welcome by patient.

The purpose of this utility model aims to provide the rectum of a kind of simple in structure, fluid that cost is low, easy to use, semifluid etc. or the full dose administrator of other tracts.

This utility model is made tract full dose administrator (Fig. 1 is a general assembly drawing by designing following structure, Fig. 2 is the right view of Figure 1A A face, Fig. 3 is the vertical view of Fig. 2 BB face): anterior for conical cylinder type shell 1, pushing ram 2, be installed in front end in the pushing ram sealing ring 3, be positioned at the cylinder type outer casing back be contained in alignment pin cotter way alignment pin 4 and be placed on cylinder type shell top cap stopper 5 formations, can adopt glass, plastics or other macromolecule polymeric materials to make.Front portion, pushing ram 2 top is conical, have 0～10 groove on the middle front part surface and can embed the cylinder of 0～10 sealing ring 3, the middle part is different shapes such as cross, triangle, bifurcation type, cylindrical shape, cylindrical or rhombus, and has 1～20 and can insert the fixedly groove of pushing ram of alignment pin.Be positioned at the cylinder type outer casing back and be convenient to the cotter way that alignment pin slides and be dove-tail form, triangle, circle, semi-circular or other polygons, the alignment pin that can partly insert pushing ram central slot internal fixation pushing ram can be made into insert type or spring type.Pharmaceutical preparatioies such as the fluid of the rectum for preparing or other tracts being used by the top osculum, semifluid suck in the tract full dose administrator, cover cap stopper, make medicament become a unit with package combination.Take out alignment pin and cap stopper during use, insert anus or other tracts, promote pushing ram, make medicament enter body cavity.Also can then can save alignment pin and cap stopper, face time spent suction medicament and can use with this utility model separately as administrator usefulness.

This tract full dose administrator front end is the conical tract that inserts easily, and pushing ram and shell closely cooperate, and promote pushing ram and can carry out full dose administration, almost noresidue medicinal liquid.Administrator is equipped with alignment pin, makes to touch the unlikely generation slip of pushing ram when transporting or moving accidentally and release medicinal liquid.The administrator top covers with a cap stopper, faces with before taking out, and can guarantee hygienic requirements.This tract full dose administrator is generally made disposable product and is used.
