Abstract
The utility model discloses a conduit type puncture needle comprising a pipe, a pipe base, a needle body, a needle handle, wherein, the pipe is connected with a pipe base and provided with scale. The needle body is connected with the needle handle and is positioned in the pipe with a pipe extending from the front end of the needle body. The front part of the needle body is provided with a plurality of suck-in holes. The utility model is characterized in that due to the suck-in holes are arranged in the front end of the needle body, the speed of bloodsucking is speeded up, meanwhile, the suck-in holes are not easy to be blocked, and the scale on the pipe is favorable to know the depth of puncture.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of puncture needle of sampling usefulness when being used for blood routine and checking.
Background technology
During clinically to routine examinations such as cardiovascular inspection, hemodialysis, all will carry out artery and vein puncture sampling, existing artery and vein piercing method is the puncture needle with the band inner core, penetrate blood vessel after, proceed in the lumen of vessels, the needle point end is provided with delivery hole.Mainly there is following problem in this common puncture needle: the one, and puncture needle all is the tubule footpath, owing to caliber carefully is difficult for extracting out clot, because the end has only a little suction hole, the suction hole is easily blocked simultaneously; The 2nd, common puncture needle is owing to lack scale, and whether needle point thrusts blood vessel can't be judged that operator only estimate paracentesis depth by rule of thumb and stop pin.
Summary of the invention
The purpose of this utility model is exactly to inhale the problem that the hole is easily stopped up, is difficult for judging paracentesis depth at the puncture needle that existing puncture needle exists, and provides that a kind of puncture pin hole is difficult for stopping up, blood drawing piece speed is fast, and easily observes the puncture needle of paracentesis depth.
The purpose of this utility model is to realize like this, this puncture needle comprises parts such as conduit, catheter block, needle body, needle handle, described conduit is connecting catheter block, described conduit is provided with scale, described needle body is connecting needle handle, needle body is positioned at conduit, and its front end stretches out conduit, and the leading section of described needle body is provided with a plurality of suctions hole.
Because adopt said structure, the beneficial effects of the utility model are: be provided with a plurality of suctions hole at the needle body leading section, accelerated the speed of aspirate clots, inhale the hole simultaneously and be difficult for stopping up, on conduit, be provided with scale, be convenient to grasp paracentesis depth.
Description of drawings
Fig. 1 is a cutaway view of the present utility model
Among the figure: 1, conduit 2, needle body 3, needle handle 4, catheter block 5, suction hole 6, scale
The specific embodiment
As shown in Figure 1, this puncture needle comprises parts such as conduit 1, catheter block 4, needle body 2, needle handle 3, conduit 1 is cylindric, can make of stainless steel material, is structure as a whole with catheter block 4, for ease of observing paracentesis depth, be provided with scale 6 on conduit 4, needle body 2 is connecting needle handle 3, and needle body 2 is positioned at conduit 1, its front end stretches out conduit 1, and the leading section of needle body 2 is provided with a plurality of suctions hole 5.Owing to be provided with a plurality of suctions hole 5 at needle body 2 leading sections, accelerated the speed of aspirate clots, inhale the hole simultaneously and be difficult for stopping up, on conduit, be provided with scale 6, be convenient to grasp paracentesis depth.
