Abstract

A pulvis medicine doser belonging to medicine dosing equipment for confecting pulvis medicine during transfusion is provided, which comprises a long needle tube, a long needle tube stand, a notch board, a chamber tube, a chamber tube stand, a tube, a short needle tube stand and a short needle tube. Wherein, the long needle tube, a tapping pipeline and a tapping theca tube inside the long needle tube stand, the tapping pipeline and a tapping tube inside a theca tube stand, the theca tube inside the short needle tube stand and the short needle tube are connected in sequence to form a closed tapping pipeline; a drug dissolving pipeline and a drug dissolving theca tube inside the long needle tube stand, the drug dissolving pipeline and a drug dissolving tube inside the theca tube stand and the drug dissolving pipeline inside the short needle tube stand are connected in sequence to form a closed a drug dissolving pipeline. The liquid medicine inside the pipeline flow to fulfill the dosage through the theca tube's expansion and compression together with the action of a one-way valve. The medicine doser can be used for glass bottle, plastic bottle and transfusion bag without pollution; in addition, the liquid medicine inside the bottle will not overflow outward, thus prevents the waste and the pollution. The utility model is mainly applied in the clinic dosage field.

Description

The powder-type drug feeding device

Technical field

This utility model relates to a kind of medicinal equipment that adds, the dosing equipment of medicine powder preparation usefulness when being a kind of patient infusion specifically.

Background technology

The drug feeding device of medicine powder preparation usefulness is made up of fluid-through tube road, long breather line, short breather line clinically at present, during use, the aerating in infusion bottle of long breather line, the infusion bottle internal pressure increases, the infusion bottle inner liquid medicine flows into medicine bottle by the fluid-through tube road, and air is come out by short breather line in the medicine bottle, and long breather line is bled in infusion bottle, the infusion bottle internal pressure reduces, and the medicine bottle inner liquid medicine flows in the infusion bottle by the fluid-through tube road.Like this, when the medicine bottle inner liquid medicine is expired, easily overflow, cause waste, pollute, in addition, thisly add, drawing liquid relies on increase and the minimizing of infusion bottle pressure to carry out, can only be in use on the vial etc., for plastic bottle, transfusion bag etc., owing to can not form malleation or negative pressure, or formation speed is slow, and this drug feeding device can't use, and still can only substitute with the bigger syringe of problems such as pollution this moment.

Summary of the invention

The purpose of this utility model provides a kind of medicinal liquid and can not overflow, and can not waste, pollute, and can both use in flexible packages such as vial and plastic bottle, transfusion bag, and not have the drug feeding device of problems such as pollution.

Technical scheme

Main body of the present utility model is two enclosed fluid-through tube roads; Take out pencil road and molten pencil road, it is by the minute hand pipe, the minute hand base, frid, the capsule pipe, auditory tube base, flexible pipe, the hour hand base, the hour hand pipe is formed, the minute hand tube cavity, drawing liquid pipeline in the minute hand base, drawing liquid capsule tube cavity, drawing liquid pipeline in the auditory tube base, the drawing liquid flexible pipe, drawing liquid pipeline in the hour hand base, the hour hand tube cavity connects successively, constitute an enclosed pencil road of taking out, minute hand base inner dissolution channel, dissolution auditory tube, the auditory tube base inner dissolution channel, molten medicine flexible pipe, hour hand base inner dissolution channel connects successively, constitute another enclosed molten pencil road, the drawing liquid pipeline of minute hand base and auditory tube base, one one-way valve is arranged respectively in the molten pencil road separately, one-way valve only allows the liquid one-way flow in the pipeline, the two ends of frid are connected on minute hand base and the auditory tube base, the groove front portion of the size shape of frid and compression pump is supporting, frid is put into the groove of compression pump, can be with the groove sealing of compression pump, frid internal ring cover drawing liquid capsule pipe and dissolution auditory tube, drawing liquid capsule pipe and dissolution auditory tube good springiness, retractility is big, connect drawing liquid pipeline and molten pencil road in the auditory tube base, the groove rear portion of auditory tube base size shape and compression pump is supporting, drawing liquid capsule pipe and dissolution auditory tube internal pressure are greater than the capsule pipe when outer, drawing liquid capsule pipe and dissolution auditory tube magnify, internal memory is received more liquid, when drawing liquid capsule pipe and dissolution auditory tube internal pressure are lower than outside the capsule pipe, the capsule pipe is subjected to flattened, interior liquid emptying, effect through one-way valve, liquid one-way flow in the pipeline, liquid flows into the medicine bottle end from the infusion bottle end in the molten pencil road, take out in the pencil road liquid and flow into the infusion bottle end from the medicine bottle end, adding like this, drawing liquid, only rely on the stretch-draw and the compression of drawing liquid capsule pipe and dissolution auditory tube, do not rely on the infusion bottle internal pressure, thereby at vial, plastic bottle, can both use on the transfusion bag, and it take out the sealing of pencil road and molten pencil road, good airproof performance, there are not problems such as pollution, in addition, it need not lack breather line, medicinal liquid can be not excessive, can not waste, pollute.

Beneficial effect

Compare with the present drug feeding device of usefulness clinically, it is formed the enclosed pencil road, molten pencil road taken out with minute hand pipe, minute hand base, frid, capsule pipe, auditory tube base, hour hand base, hour hand pipe and replaces fluid-through tube road, long breather line that original dependence pressure of the inside of a bottle operates, lacks breather line, make it on vial, plastic bottle, transfusion bag, can both use, there are not problems such as pollution, and medicinal liquid can be not excessive, do not waste, pollutes.
