Abstract
The utility model relates to a vacuum tube hemospast, it comprises test tube and syringe needle, and the evacuation in the test tube, the mouth of pipe are sealed with the rubber buffer, and two ends of syringe needle are the needle point, and test tube and syringe needle are adorned on the pipe support together, and the test tube centre gripping can remove and make its rear end puncture the rubber buffer and insert in the test tube to the syringe needle direction in the elasticity of pipe support presss from both sides. The tube extractor utilizes the negative pressure in the test tube to extract blood, the blood extraction is quick and convenient, the test tube can be directly checked, and the needle head is disposable.
Description
This utility model relates to a kind of vacuum tube hemospast, belongs to medical apparatus and instruments.
At present, the collection of blood is many makes hemospast with ordinary syringe, and needle tubing is reused, and easily produces cross infection.Though once the property hemospast appears on the market, design unreasonablely mostly, the blood drawing resistance is big, uses inconveniently, thereby is difficult to further promote the use of.
The purpose of this utility model provides a kind of vacuum tube hemospast, and it is simple in structure, and is easy to use, and disposable use, avoids cross infection and specimen to pollute.
This utility model vacuum hemospasia device is made up of test tube and syringe needle, evacuation in vitro, the mouth of pipe is with rubber stopper seal, syringe needle two ends are needle point, test tube and syringe needle are with being loaded on the pipe support, test tube clamp is held in the elasticity folder of pipe support and can moves to the syringe needle direction, and syringe needle rear end needle point is punctured in the rubber stopper insertion tube.
During blood drawing, the syringe needle front end needle point of this hemospast is thrust vein blood vessel, push test tube to syringe needle then, make the needle point of syringe needle rear end puncture rubber stopper and insert in vitro, make blood automatic suction in vitro because of the effect of negative pressure in vitro this moment.Test tube can indicate scale, so that show the blood drawing amount, can make different size as required simultaneously, inboard wall of test tube can add as required with or without anticoagulant.
As mentioned above, this utility model hemospast adopts the vacuum principle that blood is extracted out fast, and is easy to use, cross infection is avoided in the disposable use of needle tubing, and the test tube behind the suction blood can directly be sent to chemical examination, need not to be equipped with in addition test tube, simplified operation, and can avoid blood sample contaminated.This hemospast structure is very simple, low cost of manufacture.
Below in conjunction with description of drawings embodiment of the present utility model.Accompanying drawing is the structural representation of utility model hemospast.As shown in the figure, syringe needle 1 and vacuum test tube 4 are housed on the plastic processing frame 2, the two is on same axis, and vacuum test tube also can move axially in the elasticity folder by elasticity folder 21 folders are special, and the mouth of pipe is with rubber stopper 3 sealings, and syringe needle two ends are needle point.During blood drawing, front end needle point 11 is thrust the human vein blood vessel, then test tube 4 is promoted to the syringe needle direction, make rear end needle point 12 that rubber stopper 3 is punctured and inserts in vitro, in promptly automatic rapidly extraction of blood and the injecting tube 4, preceding needle point is transferred to from vein blood vessel, i.e. blood drawing finishes, test tube can directly be sent to chemical examination and detect, and syringe needle and plastic processing frame are discarded.Glass is used in the test tube selection more, also can select other new materials for use.
Claims (2)
1, vacuum tube hemospast, form by syringe needle and test tube, it is characterized in that evacuation in vitro, the mouth of pipe is with rubber stopper seal, syringe needle two ends are needle point, test tube and syringe needle be with being loaded on the pipe support, and test tube clamp is held in the elasticity folder of pipe support and can moves and make the syringe needle rear end puncture rubber stopper to the syringe needle direction and insert in vitro.
2, vacuum tube hemospast according to claim 1 is characterized in that described vacuum test tube indicates scale, simultaneously can make different size as required, inboard wall of test tube can add as required with or without anticoagulant.
