Description

A kind of syringe cylinder of energy one-handed performance

Technical field

This utility model belongs to syringe.

Background technology

At present all must use syringe in blood drawing or the medical act such as to have an injection, and nursing staff is except operating syringe, when carrying out above-mentioned action, also must first sterilize in advance with Cotton Gossypii on the skin of the patient, in conventional procedures, the left hand of nursing staff needs contact on patient skin, to sense blood flow; Execute pin blood drawing with the right hand simultaneously, but because existing injector designed is bimanualness, therefore the doctor anyway be skilled in technique is when single-hand operated syringe, still the only a little distance of stretchy, cannot once complete blood drawing action, therefore nursing staff must utilize left hand to help syringe, and right hand pull bar could complete smoothly.

Utility model content

All be bimanualness and the deficiency of inconvenience to overcome existing syringe, this utility model provide a kind of can the syringe cylinder of one-handed performance, the syringe cylinder of this energy one-handed performance can not only singlehanded complete operation, and safe and convenient.

This utility model solves the technical scheme that its technical problem adopts: a kind of can the syringe cylinder of one-handed performance, comprise, one syringe, one body of rod, its structure is: the inside of described syringe has the accommodation space of two ends and ft connection, the opening of described syringe one end extends forward and is apered to a junction, and described connecting portion is combined with syringe needle; Described body of rod one end is provided with closely sealed assembly, the end face of the described body of rod other end extends a flange, described flange side is provided with the push rod parallel with the described body of rod, the closely sealed assembly end of the described body of rod is plugged in the accommodation space of described syringe, and described push rod is positioned at the outside of described syringe, described push rod end is provided with a press section, and the last edge of described press section is parallel with the root edge of described closely sealed assembly, and the inner side of described press section is convexly equipped with a stop part.

The beneficial effects of the utility model are that one hand can operate, promote singlehanded extract or injection time syringe and the body of rod draw advance from, reduce the unstability that existing syringe produces when singlehanded and both hands blocked operation.

Detailed description of the invention

Detailed description of the invention of the present utility model is, as shown in the figure:

Embodiment 1, a kind of syringe cylinder of energy one-handed performance, please refer to shown in Fig. 1-3, comprise, one syringe 10, body of rod 20, its structure is: described syringe 10 inside has the accommodation space 11 of two ends and ft connection, the opening of this syringe 10 one end extends forward and is apered to a junction 12, and this connecting portion 12 provides in conjunction with a syringe needle 121; The described body of rod 20 one end is provided with closely sealed assembly 21, the other end end face of this body of rod 20 extends a flange 22, the side of this flange 22 is provided with a push rod 23 parallel with this body of rod 20, this body of rod 20 is plugged in the accommodation space 11 of this syringe 10 by one end of this closely sealed assembly 21, and this push rod 23 is positioned at the outside of this syringe 10; The end of above-mentioned push rod 23 is provided with a press section 24, a stop part 241 is convexly equipped with inside it, and the last edge of this press section 24 and the root edge of this closely sealed assembly 21 are isometric flush and parallel corresponding, make the amount of movement of the closely sealed assembly of press section 24 and this 21 equal, user by the position comparison scale of press section 24, can more intuitively judge the required capacity extracting blood or medicament; Above-mentioned stop part 241 also can be arranged on the end of push rod 23, is not limitedly arranged on press section 24, is arranged on push rod 23 end and also can has same effect.

Please refer to shown in Fig. 4, Fig. 5, the using state schematic diagram of this utility model syringe cylinder, to show the mode of various gripping this utility model syringe cylinder, user can with one-handed performance this utility model syringe cylinder, user hold this utility model syringe cylinder after, thumb is placed on press section 24, then with thumb promote push rod 23, make the body of rod 20 mobile in the accommodation space 11 of syringe 10, and then complete injection or extract action.

Be illustrated in figure 6 another using state schematic diagram of this utility model syringe cylinder, syringe except be used in patient with it except, must first extracting liquid medicine before injecting, therefore in the 6th figure, this utility model syringe cylinder then presents plumbness, its start principle and operational approach same as described above, user can easily with singlehanded and stable mode extracting liquid medicine, and its occupation mode is similar to the above, is changed into press section 24 pushing away towards syringe needle 121 direction towards extrapolation.
