Description

Double syringe
Technical field
This utility model relates to a kind of double syringe, belongs to technical field of medical instruments.
Background technology
In clinical practice, health care workers's syringe used is generally single hose, the end of needle tubing is provided with syringe needle, the inside of needle tubing is provided with piston and push rod, syringe needle is provided with pinhead sleeve, first pinhead sleeve is taken off during use, syringe needle is inserted in the medicinal liquid bottle needing injection, twitch piston, medicinal liquid is sucked in needle tubing then drain bubble in needle tubing and injectable slowly, when patient injection is complete, nurse needs the quick-moving speed of another to take out cotton balls, by cotton balls gently by the pinprick position being pressed in syringe needle, then syringe needle is extracted fast, therefore two hands quick-fits are needed to complete this action, but the unskilled medical personnel of action sometimes will feel in a rush, and need again when the medicinal liquid that client need injection volume is comparatively large or two kinds different again to change needle tubing and syringe needle suction medicine, use operates, and some is inconvenient, particularly when clinical rescue, time is valuable, replacing syringe is again injected and sometimes can be delayed rescue time.
Summary of the invention
The purpose of this utility model terminates to can only inject a kind of drug use when solving the use of above-mentioned single syringes at every turn the shortcoming that another hands of rear needs separately gets the inconvenience of cotton balls pressing operation, provide a kind of structure simple, compact to design, syringe needle easy to use is provided with the double syringe of cotton balls.
This utility model adopts following technical scheme: a kind of double syringe, comprise syringe, the lower end of described syringe is provided with projection for connecting needle, be provided with central dividing plate in the inner chamber of described syringe and syringe be divided into the first evenly equal syringe and the second syringe, piston and push rod is respectively arranged with in described first syringe and the second syringe, the centre of described syringe and projection is provided with movable valve circle, be provided with and the first syringe in described movable valve circle, the catch that the caliber mouth of the second syringe is identical, upper end and the projection intersection arranged outside of described syringe needle have cotton balls circle.
Further, the outer wall of described syringe is provided with antiskid thread.
Further, described syringe needle is provided with at least one aperture.
Further, the top and bottom of described movable valve circle are provided with groove for connecting the projection of syringe and syringe lower end.
This utility model structure is simple, design ingenious, the setting of double cylinder can the different medicine of a shot two kinds without the need to changing syringe, simplify the operating procedure of medical personnel, safe and convenient to use, when clinical rescue patient carries out intravenous injection, for patient wins rescue time, also reduce micro-bubble when syringe needle is connected with venous line simultaneously and enter the risk of venous line, the antiskid thread that syringe is arranged can prevent hands in operating process sliding, injection terminate rear directly by the cotton balls of syringe needle upper end by pinprick place, convenient and swift.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of movable valve circle of the present utility model.
Reference numeral: the first push rod 1, second push rod 2, first syringe 3, second syringe 4, first piston 5, second piston 6, movable valve circle 7, catch 8, projection 9, syringe needle 10, cotton balls circle 11, upper recess 12, lower end groove 13, central dividing plate 14.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of double syringe, comprise syringe, the lower end of syringe is provided with projection 9 for connecting needle 10, be provided with central dividing plate 14 in the inner chamber of syringe and syringe be divided into the first evenly equal syringe 3 and the second syringe 4, first piston 5 and the first push rod 1 is provided with in first syringe 3, the second piston 6 and the second push rod 2 is provided with in second syringe 4, movable valve circle 7 is provided with between syringe and projection 9, the top and bottom of movable valve circle 7 are respectively arranged with upper recess 12 and lower end groove 13, the lower limb of syringe is fastened in the upper recess 12 of movable valve circle 7, the top edge of projection 9 is fastened in the lower end groove 13 of movable valve circle 7, be provided with in movable valve circle 7 and the first syringe 3, the catch 8 that the caliber mouth of the second syringe 4 is identical, the below of movable valve circle 7 directly communicates with the projection of syringe lower end, upper end and the projection 9 intersection arranged outside of syringe needle 10 have cotton balls circle 11, syringe needle 10 is provided with at least one aperture, the outer wall of syringe is provided with antiskid thread.
Using method: rotary moveable valve circle 7 during suction medicine, its catch 8 is made to block the second syringe 4 completely, medicinal liquid is made directly to enter in the first syringe 3 through syringe needle 10 and movable valve circle 7, after sucking the medicinal liquid in the first syringe 3, timely rotary moveable valve circle 7, with catch 8, first syringe 3 is blocked completely, prevent the medicinal liquid in the first syringe 3 from flowing out, now can inhale medicine smoothly in the second syringe 4, antiskid thread on syringe outer wall can prevent the hands when inhaling medicine from sliding, inject after the medicinal liquid in the second syringe 4 without the need to extracting syringe again, directly can carry out the drug injection in the first syringe by rotary moveable valve circle 7, syringe needle 10 is provided with at least one aperture, the pressure of patient injection site can be reduced, ease the pain sense, after injection terminates can directly by the cotton balls circle 11 of syringe needle 10 upper end setting by pinprick place, decrease operating procedure, when clinical rescue patient carries out intravenous injection, for patient wins rescue time, also reduce micro-bubble when syringe needle is connected with venous line simultaneously and enter the risk of venous line.
