Abstract

The utility model relates to a medical instrument, in particular to a syringe capable of guiding guide wires therein, which is used for clinical venous retention, parenchymatous organs, body fluid lumen extract and the like. The syringe comprises a syringe body with a needle head; a roll booster provided with a piston is inserted into the syringe body; the center of the roll booster is provided with a through hole; the front end of the roll booster is connected with a section of transition tube communicated with the through hole of the center of the roll booster; and the opening of the front end of the transition tube is aligned to the injection port of the front end of the syringe body. The syringe capable of guiding the guide wires therein not only has convenient use but also has simple structure and low manufacture cost, so the hospitalization cost burden is relieved for patients.

Description

Can import the syringe of seal wire

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly with a kind of syringe that is used for the imported seal wire of needs such as clinical vein indwelling, substantial viscera and body fluid chamber drawing liquid.

Background technology

The syringe of present imported seal wire, be with a hollow metal tube in general its booster, and and syringe link, be with a valve in the hollow metal tube, one side sky is arranged before the valve, the syringe of imported seal wire like this is complex structure not only, and cost is very high, has increased patient's the cost burden of seeing a doctor greatly.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of syringe of simple in structure, imported seal wire that cost is low is provided.

The syringe that imports seal wire of the present utility model comprises the syringe that has syringe needle, in syringe, be inserted with a booster that piston is installed, described booster center has a through hole, be connected with one section transition conduit that communicates with the through hole at its center at the booster front end, the front opening of transition conduit is aimed at the injection port of syringe front end.

The syringe that imports seal wire of the present utility model is not only easy to use, and it is simple in structure, cheap for manufacturing cost, has alleviated patient's medical expense burden.

Fig. 4 is that the B of booster of the present utility model is to structural representation.

The specific embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the syringe that imports seal wire of the present utility model comprises the syringe 2 that has syringe needle 1, in syringe 2 interpolations booster 3 is arranged, piston 4 is installed on the booster, the booster center has a through hole 31, be connected with one section transition conduit 32 that communicates with the through hole at its center at the booster front end, the front opening of transition conduit is aimed at the injection port 21 of syringe 2 front ends.

Using method when this utility model is used for the internal jugular vein indwelling is:

Conventional to skin location, sterilization, anesthesia; Use syringe shown in Figure 1, draw booster 3 before the puncture slightly, make transition conduit 32 slightly from the injection port 21 of syringe, preventing that blood from refluxing directly enters booster, and the right hand is held syringe 2 and booster 3 and syringe needle 1 is thrust skin gone into internal jugular vein, sees that blood flows into syringes from injection port 21, left hand is held syringe 2, prop up the inlet of the through hole 31 of booster rear end with hand thumb, and aspirate, as non-resistance, the smooth and easy outflow of blood, promptly determine to enter internal jugular vein, unclamp hand thumb, push back booster, make transition conduit 32 on the booster be close to the injection port 21 of syringe, import seal wire from the through hole inlet of booster rear end, transfer to syringe, import and keep somewhere flexible pipe.

Claims

1. syringe that can import seal wire, comprise the syringe (2) that has syringe needle (1), in syringe, be inserted with the booster (3) that piston (4) have been installed, it is characterized in that: described booster center has a through hole (31), be connected with one section transition conduit that communicates with the through hole at its center (32) at the booster front end, the front opening of transition conduit is aimed at the injection port (21) of syringe front end.
