Abstract
The utility model discloses a safety blood sampler. The safety blood sampler comprises a syringe tube, a piston and a piston rod, wherein the piston is arranged in the syringe tube, the piston and the syringe tube form a sealed cavity, the piston rod extends out of the syringe tube, and the cross section of the piston rod is in the shape of a cross. A round pressing part is arranged at one end, far away from the piston, of the piston rod. The pressing part and the piston rod are of an integrated structure. A through tube is arranged at the front end of the syringe tube, a puncture needle is arranged at one end, far away from the syringe tube, of the through tube, and scales are arranged on the outer wall of the syringe tube. The outer wall of the syringe tube comprises a see-through prevention layer, a liquid getting hole is formed in the position, close to the through tube, of the wall of the syringe tube, and a rubber layer seals the interior of the liquid getting hole. Through the see-through prevention layer, blood drawing personnel can avoid seeing blood in the syringe tube so that blood faint accidents can be avoided. Through the liquid getting hole, blood can be sampled conveniently and can be prevented from splashing around.
Description
Technical field
This utility model relates to a kind of safe hemostix.
Background technology
At present, the hemostix that medical institutions are used, normally disposable syringe, although use disposable syringe more convenient in the time of blood sampling, but because disposable syringe itself cannot can be placed in assay device as chemical examination with test tube, blood sample must be transferred to in vitro can chemically examining blood sample collection of chemical examination use; In addition, with disposable syringe to chemical examination when shifting blood sample in test tube, easily generation, because operator's carelessness blood spatters, also exists operator to stab because of carelessness the accident of oneself outward.
Meanwhile, part is had the symptom of dizzy blood by blood drawing personnel, and existing syringe is mostly transparent plastic and makes, and can cause dizzy mass formed by blood stasis shape by blood drawing personnel while being seen the blood in needle tubing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of safe hemostix, and this apparatus surface is coated with anti-perspective layer, can effectively avoid the generation of dizzy blood accident, by set liquid outlet, facilitates blood sampling simultaneously.
For addressing the above problem, this utility model adopts following technical scheme:
A kind of safe hemostix, comprise a needle tubing, and be arranged in needle tubing, and form the piston of a sealed cavity with described needle tubing, and connect this piston, and extend to the piston rod of needle tubing outside, the cross section of described piston rod is cross, described piston rod has a press section away from one end of piston, this press section is circular, and described press section and piston rod are integral type structure, described needle tubing front end has a siphunculus, this siphunculus has puncture needle away from one end of needle tubing, the outer wall of described needle tubing has scale, on the outer wall of described needle tubing, include anti-perspective layer, this anti-perspective layer has a groove relative with described scale, on the tube wall of described needle tubing, be provided with a liquid outlet near siphunculus place, in this liquid outlet, be sealed with rubber layer, in described anti-perspective layer, there is a hole relative with described rubber layer.
As preferred technical scheme, one end that described press section deviates from piston rod has the sphere that rubber is made.
As preferred technical scheme, described anti-perspective layer is that coloured plastics material is made.
As preferred technical scheme, described needle tubing has a force section away from one end of siphunculus, and this force section is oval, and described needle tubing and force section are integral type structure.
The beneficial effects of the utility model are: by set anti-perspective layer, can avoid being seen the blood in needle tubing by blood drawing personnel, avoid dizzy blood accident, by set liquid outlet, can facilitate the sampling of blood axil, avoid blood to flash, and the structure of this device is comparatively simple, be applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
