Abstract

The utility model belongs to a medicine adding apparatus for a medicine delivery device to carry out dosage. The utility model is composed of a liquid duct and a long air duct which are arranged in parallel, wherein the liquid duct is formed by the mutual connection of an inner duct of a long needle tube 2, a liquid tube 12, a liquid leather hose 13, a short liquid tube 15 and a short needle tube 8, and the long air duct is formed by the mutual connection of a long air tube 11, an air leather hose 5 and a long air port 10. The medicine adding apparatus can realize automatic dosage by controlling the air-in and the air-out of each duct. The utility model has the advantages of cross infection prevention, convenient operation, little consumption of medicine, etc.

Description

Drug feeding device

This utility model belongs to a kind of dispensation apparatus, especially a kind of infusion bottle dispensation apparatus.

For a long time, the drug feeding device of Shi Yonging is made up of syringe needle, syringe clinically, the medical worker arrests syringe with hands during use, syringe needle is stretched in the liquid medicine bottle of breakdown, runs into the timing that adds of medicine powder, also need aerating in airtight infusion bottle, drawing liquid, add aerating in the airtight ampoule, drawing liquid, add in the airtight infusion bottle again, syringe needle, syringe usually are repeatedly used like this, the easy contact needle of medical worker's hands, easily bring unpurified gas into, directly or indirectly pollute medicinal liquid.Resistance is bigger during drawing liquid, and medicinal liquid has residual, causes the inconvenient operation of dosing process, and medicinal liquid is wasted, and has increased the chance that cross infection takes place.

The purpose of this utility model provides a kind ofly can avoid cross infection, the drug feeding device that drug waste is few and easy to operate.

For achieving the above object, technical solution adopted in the utility model is: it is made of side by side fluid-through tube road and long breather line two parts, the fluid-through tube road is interconnected and is formed by minute hand pipe interior conduit, fluid-through tube, logical liquid leather strap, short fluid-through tube, hour hand pipe interior conduit, and long breather line is interconnected and formed by long breather, ventilation leather hose, long blow vent.

Compare with traditional drug feeding device, this utility model adopts long breather line, short breather line, fluid-through tube road control medicine adding and dispensing, realizes control automatically.The medical worker can directly or indirectly not contact pipe interior, and aerating is bled by electronic control, more laborsaving.Medicinal liquid can not remain in the pipeline the inside, and is difficult for outflow.Therefore can avoid cross infection and easy to operate, drug waste is few.

Below in conjunction with drawings and Examples this utility model is described in further detail.

Accompanying drawing is the structural representation of this practical drug feeding device.

Drug feeding device shown in the drawings, by minute hand pipe 2, be enclosed within the minute hand pipe box 3 on the minute hand pipe 2, minute hand base 4, hour hand pipe 8, be enclosed within the hour hand pipe box 14 on the hour hand pipe 8, hour hand base 6, ventilation leather hose 5, logical liquid leather hose 13 is formed, minute hand pipe 2 and minute hand pipe box 3 are plugged on an end of minute hand base 4 together, hour hand pipe 8 and hour hand pipe box 14 are plugged on an end of hour hand base 6 together, the other end of minute hand base 4 and hour hand base 6 is by logical liquid leather hose 13, ventilation leather hose 5 links together, form long breather line, short breather line, fluid-through tube road three parts, minute hand pipe 2, hour hand pipe 8 ventilation leather hoses 5, in the logical liquid leather hose 13 penetrating pipeline is arranged, hour hand pipe box 14, there is interior conduit minute hand pipe box 16 inside, its sidewall has the hole, long breather 11 and logical liquid leather hose 12 are arranged in the minute hand base 4, short breather 13 is arranged in the hour hand base 6, short fluid-through tube 15, short blow vent 7, long blow vent 10.

The fluid-through tube road is interconnected and is formed by minute hand pipe 2 interior conduits, fluid-through tube 12, logical liquid leather strap 13, short fluid-through tube 15, hour hand pipe 8, and long breather line is interconnected and formed by long breather 11, ventilation leather hose 5, long blow vent 10.

A short breather line also is set on the fluid-through tube road, and short breather line is interconnected and is formed by hour hand pipe box 14 interior conduits, short breather 16, short blow vent 7.

Be with long sheath 1 on the minute hand pipe 2, be with short sheath 9 on the hour hand pipe 6.

Minute hand pipe 2 is the side opening pin with hour hand pipe 7, two ends, fluid-through tube road are point, can thrust in the plug of infusion bottle easily, breather line is positioned at a side in fluid-through tube road, can be divided into two, next door by two ends, fluid-through tube road leads to the logical intermediary next door of liquid leather strap respectively, in long blow vent 10 and the short blow vent 7 filter membrane 17 is arranged, and can filter the unpurified gas such as antibacterial that pass through.During use, the minute hand pipe 2 of Mediated strap thrusts in the plug of infusion bottle, and hour hand pipe 8 thrusts in the plug of powder ampoule, and the long blow vent 10 of breather line is placed on the breather of air pump.Like this, the breather of powder ampoule, fluid-through tube road, infusion bottle, breather line and air pump has been formed a runner pipe.

When the air inlet switch of opening air pump, gas enters air pump by breather line in the infusion bottle, and liquid medicine is inhaled in the infusion bottle in the powder ampoule, opens air pump and goes out air cock, and gas after filtering enters in the infusion bottle, the powder dissolving.
