Abstract
The utility model belongs to medical instruments, particularly relates to a one-tube two-liquid syringe, which comprises a needle head, a piston tube body and piston rods with rubber pads; the piston tube body is divided into two semi-cylindrical inner chambers through a baffle plate in the piston tube body along the length direction, two inner chambers are respectively communicated with two liquid passages in the needle head side by side; and two piston rods are arranged side by side, and the semicircular rubber pads are respectively fixed at the tail ends of the two piston rods. A hole is formed at the front end of one of the two liquid passages in the needle head, and a side hole is formed on the side surface of the other liquid passage. A rubber needle cap capable of covering a hole on the needle point is arranged at the front end of the needle head. The one-tube two-liquid syringe has the benefits of simple structure and convenient use, and can inject two different liquid medicines simultaneously in one time of injection, thereby reducing the times of injection and the workload of medical staff, enhancing the work efficiency and alleviating the pain of patients.
Description
(1) technical field
This utility model relates to a kind of medical apparatus and instruments, a particularly a kind of pipe two liquid syringes.
(2) background technology
The intramuscular injection device of present clinical use, syringe has only the cavity of a powder charge, has only injection orifice of needle tip on the pin stalk of syringe needle part, when injecting two kinds of medicinal liquids, gradation is injected often, the people of especially long-term injection, and having an injection on health is difficult to find suitable position, sometimes have an injection and get to the position of having an injection in the past, very pain.
(3) summary of the invention
This utility model is in order to remedy the deficiencies in the prior art, and a kind of simple in structure, easy to use a, pipe two liquid syringes that can inject two kinds of medicinal liquids simultaneously are provided.
This utility model is achieved by the following technical solution:
A pipe two liquid syringes of the present utility model, the piston rod that comprises syringe needle, piston body and band rubber blanket, its special character is: described piston body inside has along its length a dividing plate that it is divided into two half-cylindrical inner chambers, two inner chambers are communicated with two fluid passages side by side in the syringe needle respectively, piston rod is side by side two, and the end of two piston rods is fixed semicircle rubber blanket respectively.
A pipe two liquid syringes of the present utility model in order to prevent the cross reaction of different pharmaceutical, are located at different places with the fluid position of syringe needle.Two fluid passages of described syringe needle wherein one be the front end perforate, another opens side opening for the side.
A pipe two liquid syringes of the present utility model for the ease of sucking medicinal liquid, are provided with the rubber pin medicated cap in the hole that can cover on the needle point at the syringe needle front end.
The beneficial effects of the utility model are, and are simple in structure, easy to use, prick one time pin, can inject two kinds of different medicinal liquids simultaneously, reduce the number of times of acupuncture treatment, thereby reduce medical personnel's workload, increase work efficiency, and reduce patient's misery.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1 piston body, 2 syringe needles, 3 piston rods, 5 pin medicated caps, 6 side openings, 7 holes, 8 rubber blankets.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
A pipe two liquid syringes of the present utility model, the piston rod 3 that comprises syringe needle 2, piston body 1 and band rubber blanket 8, its special character is: described piston body 1 inside has along its length a dividing plate that it is divided into two half-cylindrical inner chambers, two inner chambers are communicated with two fluid passages side by side in the syringe needle respectively, piston rod 3 is side by side two, and the end of two piston rods is fixed semicircle rubber blanket respectively.Two fluid passages of described syringe needle 2 wherein one be front end perforate 7, another opens side opening 6 for the side.Be provided with the rubber pin medicated cap 5 in the hole that can cover on the needle point at the needle tubing front end.
Can suck different medicinal liquids at 1 two half-cylindrical inner chambers side by side of piston body when using these pipe two liquid syringes, that inner chamber that wherein is communicated with the hole 7 on the needle point sucks medicinal liquid earlier, with pin medicated cap 5 its hole 7 is blocked, in case be infected with other medicinal liquid, the side opening 6 on the reuse pin stalk sucks another kind of medicinal liquid, during injection, pull out pin medicated cap 5, side opening 6 and hole 7 are exposed, and conventional injection just so just can have been injected two kinds of medicinal liquids simultaneously.
