Abstract

A kind of disposable decoction tuner of double-deck double aseptic packagings, spiral connection prevents leakage, sealing ring pastes air-filtering membrane barrier dust, particulate matter and is immersed in conduit, double-deck double sterile manner of packings, make product more safe and reliable, the design of side-by-side needle tubing, decoction and air are mutually isolated during work, conduit will not be gone to because of air and causes reciprocal extraction, reduces labor intensity.

Description

Double-deck double sterile disposable decoction tuners

1. art

Product of the present invention is mainly used in clinical configuration decoction, dosing, molten medicine and extracts decoction.

2. background technology

The outer packing mode of the conventional molten syringe of in the market is excessively simple, individual layer aseptic plastic packaging cracky；Note There is the risk of leakage with needle stand junction in emitter；And the air filter opening of needle stand is even more the phenomenon that there is foreign matter intervention.

3. the content of the invention

From the security consideration of patient, double-deck double aseptic packaging modes improve safety；Change the filtering knot of air filter opening Structure, can more effectively obstruct dust, particulate matter etc.；Consider that syringe is connected with needle stand by spiral can be more from environmental Good reduction decoction outflow.

1. using double-deck double aseptic packaging structures, collision causes breakage when reducing improper artificial tearing when in use or placement And the air pollution produced；

2. syringe is screwed with needle stand using screw pair, and the process Chinese medicine liquid water clock that further avoids making up a prescription is polluted；

3. needle stand air filter opening, which is on conventional filter type, increases air-filtering membrane, plays dust-and-foreign-object-proof intervention Effect, it is to avoid fine dust mouthful is inhaled into medicinal liquid bottle by conventional filtration, hence into syringe；

4. exhaust needle is designed side by side with aspirating needle, independent mutually, preferably can utilize air contraction principle will when in use In decoction inhalation syringe.

4. brief description of the drawings

As shown in figure 1, the disposable decoction formulated product outside drawing of double-deck double aseptic packagings：The schematic appearance of this product.

As shown in Fig. 2 the double-deck disposable medicine dissolving device composition figure of double aseptic packagings：This product is by 1- push rods；2- pistons；3- is led Pipe；4- needle stands；5- air-filtering membranes；6- sealing rings；7- exhaust needles；8- aspirating needles；9- sheaths；10- inner packings；11- outer packings Composition.

As shown in figure 3, syringe and needle portion：Syringe and syringe needle cooperation schematic diagram, syringe lead to needle portion Cross screw pair to screw, i.e., 3- conduits are connected with 4- needle stands.

As shown in figure 4, sealing structure (sealing ring and air-filtering membrane) at air filter opening：Needle stand air filter opening is utilized The structure of sealing ring and air-filtering membrane, i.e. 6- sealing rings are pasted together with 5- air-filtering membranes, are then fitted into filtering mouth Place.

As shown in figure 5, needle stand is designed using side by side configuration：Needle stand front end is respectively mounted 2 syringe needle (7- exhaust needles；8- inhales Liquid pin), design side by side, exhaust needle is communicated with air filter opening, and aspirating needle is connected with the conduit of syringe.

5. operation principle

Ectonexine aseptic package bag is first torn when this product is used respectively, sheath is then pulled out, push rod is shifted onto conduit bottom Air in portion, discharge conduit, this decoction tuner is then inserted in medicinal liquid bottle (notice that exhaust needle will also enter medicinal liquid bottle In), now push rod starts to draw decoction toward pulling back.Now the air at air filter opening will be inhaled into exhaust needle, that is, enter Enter into medicinal liquid bottle, by push rod of pulling back always, substantial amounts of air is inhaled into bottle, due to air compression, decoction will be by It is expressed in aspirating needle, hence into conduit, until decoction is extracted totally by complete.

During decoction is drawn, the air above air filter opening is inhaled into exhaust needle, herein using sealing The design with air-filtering membrane is enclosed, particulate matter, dust can be effectively obstructed.

Because aspirating needle and exhaust needle are respectively communicated with 2 different positions：Aspirating needle connecting tube, exhaust needle connection air Mouth is filtered, the situation that just can preferably avoid decoction to be mixed with air during work, this design can effectively obstruct air Into conduit, it is to avoid reciprocal to extract, the labor intensity of decoction is allocated in greatly reduction.

Claims (5)

1. the disposable decoction tuner device of double-deck double aseptic packagings, is encapsulated with 2 aseptic package bags of different sizes, comprising other Any double-deck or multilayer aseptic packaging structure, such as：Plastic casing+aseptic package bag etc..

2. the connected mode of injector canal and needle portion：Spirally screw.

3. the decoction tuner specification all applied in the market, is not limited solely to 10ml, 20ml, 30ml, 50ml specification Tuner.

4. the structure that the sealing ring used at air filter opening is connected with filter membrane.

5. exhaust needle is designed side by side with aspirating needle, independent mutually.(syringe needle of various shape can be applied, such as angle pin, side-hole needle Deng).
