Abstract
The utility model relates to a disposable infusion apparatus with a physic liquor filter. A vein needle (1), physic liquor filters (10, 11, 12) of a Murphy's dropper type, and a bottle needle (6) are orderly connected through an infusion conduit (5); a regulator (3) is sheathed between the physic liquor filters of a Murphy's dropper type and the vein needle. The physic liquor filters of a Murphy's dropper type of the utility model can combine a Murphy's dropper and the physic liquor filters into integration, combine double functions into integration, and have the advantages of simple structure and low cost. The physic liquor filters of a Murphy's dropper type of the utility model are arranged at 80-100 cm away from the vein needle, and can effectively overcome the defects of the physic liquor filters of the existing disposable infusion device that the physic liquor filters of the existing disposable infusion device are arranged next to the vein injection needle (about 30 cm), the phenomenon of blood returning occurs during injection, a physic liquor filtering membrane is easy to block, the filtering effect is not good, and air bubbles are easy to store in the physic liquor filter and are not easy to eliminate.
Description
This utility model relates to intravenous injection medium is introduced intravital apparatus, particularly about a kind of disposable transfusion device with liquid medicine filter.
At present, the disposable transfusion device (Fig. 1) of the band liquid medicine filter that intravenous injection is adopted, its intravenous needle (1), liquid medicine filter (2), Murphy type burette (4), bottle pin (6) uses transfusion catheter (5) to connect successively, actuator (3) is enclosed within on the transfusion catheter (5) between Murphy type burette and the liquid medicine filter, pneumatic needle (7) is connected with the air inlet pipe (8) that air inlet pipe drainage screen (9) are housed, this disposable transfusion device total length is not less than 1250cm, the transfusion catheter internal diameter is not less than 25mm, its liquid medicine filter (2) is formed by two coniform shells and liquid medicine filtering membrane pressing, be located between actuator (3) and the intravenous needle (1), from about intravenous needle 30cm, locate.Liquid medicine filter by this transfusion device of what is too near from intravenous needle, when the blood back phenomenon appears in intravenous injection, reduce viscosity increased because of flowing out external blood with temperature, in the time of in liquid medicine filter flows back to body, easily liquid medicine filtering membrane is stopped up, cause filter effect not good enough, bubble easily accumulates in the drawback in the liquid medicine filter when also having aerofluxus simultaneously.
Even the purpose of this utility model overcomes above-mentioned the deficiencies in the prior art part and provides a kind of blood back phenomenon medicinal liquid that occurs during in intravenous injection to cross the medicinal liquid of device and cross film and also can not stop up at what, bubble is difficult for accumulating in the disposable transfusion device in the liquid medicine filter during aerofluxus.The purpose of this utility model realizes by following measure:
This utility model (Fig. 2) is a kind of disposable transfusion device with liquid medicine filter (Fig. 3), its intravenous needle (1), liquid medicine filter, Murphy type burette, bottle pin (6) use transfusion catheter (5) to connect successively, pneumatic needle (7) is connected with air inlet pipe (8), and air inlet pipe drainage screen (9) is housed in the air inlet pipe (8); It is characterized in that: 1, Murphy type burette and liquid medicine filter are combined into Murphy type burette formula liquid medicine filter (10,11,12), 2, actuator (3) is enclosed between Murphy type burette formula liquid medicine filter and the intravenous needle.
Murphy type burette formula liquid medicine filter of the present utility model by Murphy type burette body (10), Murphy type burette at the bottom of (12) and form every liquid medicine filtering membrane (11) in both junctions.
This utility model is located at liquid medicine filter the bottom of existing Murphy type burette, from intravenous needle 80～100cm place, when intravenous injection, can not stop up liquid medicine filtering membrane even the blood back phenomenon occurs yet, the liquid medicine filter that has overcome the prior art disposable transfusion device effectively is near from intravenous needle, during blood back liquid medicine filtering membrane easily stop up and during aerofluxus bubble easily accumulate in the defective that is difficult for eliminating in the liquid medicine filter, this utility model is combined into Murphy type burette formula liquid medicine filter with Murphy type burette and liquid medicine filter, integrate dual-use function, simple in structure, cost is low, and compared with prior art, cost can reduce by 5%.
The drawing of this utility model accompanying drawing is described as follows:
Fig. 1 is the disposable transfusion device of prior art band liquid medicine filter.
1-intravenous needle, 2-liquid medicine filter, 3-actuator, 4-Murphy type burette, 5-transfusion catheter, 6-bottle pin, 7-pneumatic needle, 8-air inlet pipe, 9-air inlet pipe drainage screen among the figure.
Fig. 2 is a kind of disposable transfusion device with liquid medicine filter of this utility model.
Among the figure at the bottom of 10-Murphy type burette body, 11-liquid medicine filtering membrane, the 12-Murphy type burette.
Fig. 3 is this utility model Murphy type burette formula liquid medicine filter.
Among the figure at the bottom of 10-Murphy type burette body, 11-liquid medicine filtering membrane, the 12-Murphy type burette.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 2, Fig. 3 are a kind of disposable transfusion devices with liquid medicine filter of this utility model, produce by prior art disposable transfusion device conventional production process flow process, when this utility model Murphy type burette formula liquid medicine filter is manufactured, earlier liquid medicine filtering membrane (11) is pressed into (12) at the bottom of the Murphy type burette, inserts Murphy type burette body (10) bonding again.
The utility model compared with prior art has the following advantages:
1, Murphy type burette formula liquid medicine filter, from intravenous needle 80～100cm, even the blood back phenomenon occurs during intravenous injection, liquid medicine filtering membrane does not stop up yet, good filtration effect.
2, Murphy type burette and liquid medicine filter are combined into one, simple in structure, manufacture cost and can reduce about 5%.
3, during exhaust in the transfusion device bubble be difficult for accumulating in the liquid medicine filter, easily get rid of.
