CN203107863U - Puncture syringe - Google Patents

Abstract

The utility model discloses a puncture syringe which comprises a syringe tube, wherein a piston is arranged inside the syringe tube and is connected with a piston push rod. The puncture syringe is mainly characterized in that finger rings are respectively arranged on two sides of the rear part of the syringe tube and the tail end of the piston push rod. In the use process of the puncture syringe by medical staff, thumbs, index fingers and middle fingers are inserted into ferrules for sucking. The application of the puncture syringe is especially suitable for positioning puncture guided by imaging; and meanwhile, single-hand operation can be realized, the complexity of operation is reduced and the working efficiency is increased.

Description

A kind of puncture injection device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of puncture injection device.

Background technology

In the modern medicine, injection is extremely important link in the medical matters operation process, so whether the reasonability used of injection technique or instrument used for injection has extremely important relation with the quality of final operation quality.Make a general survey of the syringe of present use, the terminal both sides of its syringe and the end of piston push rod all are to stand simply to adhere to a lamellar structure, though this kind structure can be finished injection operation, but lack stability, generally all be not suitable for one-handed performance, therefore the medical worker is when injecting to patient, all need two handss to operate simultaneously, this process not only operates and has certain inconvenience, greatly reduce medical worker's work efficiency, also strengthened simultaneously medical worker's work difficulty, so that the quality of finishing of work has also been had certain influence.

The utility model content

The purpose of this utility model provides easy to operate, puncture injection device that can one-handed performance again of a kind of while simple in structure.In order to realize above purpose, this utility model is by the following technical solutions: a kind of puncture injection device, comprise syringe, and syringe inside has piston, piston links to each other with piston push rod, it is characterized in that: the both sides at described syringe rear portion and the end of piston push rod are respectively arranged with finger ring.

The radius of described finger ring is 0.7cm.

This utility model does not structurally have too complicated variation, and in operating process, needle tubing can be fixed on three fingers by annular collar, thereby realize the activity of one-handed performance syringe, the accuracy of raising injection process that simultaneously can also be easy is such as the localised puncture that is applied under the iconography guiding.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1 is syringe, and 2 is first finger ring, and 3 is second finger ring, and 4 is piston push rod, and 5 is piston.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described further.

As shown in Figure 1, a kind of puncture injection device, first finger ring 2 are positioned at the terminal both sides of syringe 1 and link to each other with syringe 1 , Second finger ring 3 is positioned at piston push rod 4 ends and links to each other with piston push rod 4, piston 5 is positioned at the head end of piston push rod 4 in linking to each other, in the process of push-and-pull push rod, the piston operation person inserts forefinger and middle finger respectively in two finger rings, realizes the control to syringe 1 direction; Thumb is inserted in second finger ring 3, realization is to the control of piston 5, the outside stretching, extension of thumb namely realizes the similar operations such as absorption of medicine, and thumb compresses the similar operations such as injection that can realize medicine inwards, thereby finish injection process, whole process operation simply and only needs a hands just can realize control to injection operation.

Wherein the radius of finger ring is 0.7cm, can certainly be other radius, as 0.5cm, 0.8cm, 1cm, 1.1cm etc., can adopt different radiuses according to different needs, and this all is fine.

Claims (1)

1. a puncture injection device comprises syringe, and syringe inside has piston, and piston links to each other with piston push rod, it is characterized in that: the both sides at described syringe rear portion and the end of piston push rod are respectively arranged with finger ring; The radius of described finger ring is 0.7cm.
