Abstract
The utility model provides a blood sampling apparatus which comprises a fixation sheath with an axial hole inside. The side wall of the fixation sheath is provided with a strip-shaped placket which enables the handle of the puncture needle to move forth and back. The fore end of the handle of the puncture needle connects the puncture needle and the blood sampling needle connects the handle of the puncture needle inside the strip-shaped placket through a soft tube. The fore end of the fixation sheath is provided with a soft cork which can be penetrated by the puncture needle. The forepart of the hole behind the cork is a cone-shaped hole. The side wall of the forepart of the fixation sheath is provided with a side placket into which the cork can be put or the fore end of the fixation sheath is provided with a front placket into which the cork can be put. The cork is cone-shaped and the tine of the cone, flat or mushroom-shaped, sticks out of the plane of the fore end of the fixation sheath. The soft cork is a transparent silicone rubber cork, a latex cork, a caoutchouc cork, a butyl-rubber cork, a polythene cork, a polystyrene cork or a macromolecule cork.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of hemostix from venous blood collection.
Background technology
At present, in the hospital when carrying out venous blood collection product commonly used be the supporting blood taking needle of vacuum test tube, wherein vacuum test tube, blood taking needle are respectively products independently, are generally provided by different manufacturers.During use, earlier blood taking needle is inserted patient's vein, and then take out vacuum test tube, the blood taking needle rear end is inserted in the vacuum tube carry out blood collecting.Its shortcoming is that for avoiding blood to reflux from blood taking needle, operator must be very skilled in this process, and the operating time that allows is very limited.For this reason, relevant technologies expert has invented a kind of new hemostix, and this hemostix comprises: a fixed cover, in it is axial through hole is arranged, and there is the strip gab of a ccontaining puncture needle handle to be communicated with on the sidewall with through hole; One puncture needle, it is arranged in the described fixed cover; One blood taking needle, it is connected with described puncture needle by a flexible pipe.This hemostix is provided with the card medicated cap at the opening of vacuum test tube, on the card medicated cap, be provided with fixed cover, card medicated cap and fixed cover are taked tight inserting mode, can limit fixed cover rocks, and be provided with puncture needle in the fixed cover, the side of puncture needle also is provided with a puncture needle handle: like this in the operation of taking a blood sample, when discovery has blood back, can push the puncture needle handle of puncture needle, puncture the rubber stopper of blood taking tube opening part, normally take a blood sample, operate very simple, convenient, and safe and reliable, even be not the ten minutes experienced operators, also can finish blood sampling.This vacuum blood collector is in the center of rubber stopper, and about two sides respectively is provided with a groove, and the greater than other parts that penetrated of rubber stopper is thin like this, can reduce the resistance when penetrating, and is more convenient when the operator is operated.Weak point is that blood is wandered on operating board by the syringe needle of puncture needle when needs are changed vacuum test tube.
Summary of the invention
The purpose of this utility model provides and does not a kind ofly produce that blood is wandered and the hemostix of handled easily.
The purpose of this utility model can realize by following technical measures:
This hemostix comprises: in fixed cover is axial through hole is arranged, the strip gab that one ccontaining puncture needle handle advance and retreat are arranged on the sidewall of fixed cover, puncture connects puncture needle before the needle handle, and blood taking needle is connected with puncture needle handle in the strip gab by flexible pipe, and the fixed cover front end is equipped with the transparent soft material plug of puncture needle.
The purpose of this utility model also can realize by following technical measures:
The leading portion of the through hole at soft material plug rear portion is a bellmouth; The side opening that plugs the people for soft material is arranged on the sidewall of fixed cover front end; The preceding top of fixed cover have for soft material plug into open front; Described soft material plug is tapered, and cone tip part is flat-top or mushroom top and outwards protrudes from preceding fixed cover sinciput transverse plane; Described soft material plug is selected from transparent sillicon rubber blocking, latex plug, natural rubber plug, butyl rubber plug, vinyl stopper, polyphenyl alkene plug or macromolecular material plug; On the sidewall of described fixed cover rear end boss is arranged and be positioned on the relative sidewall of strip gab; Described puncture needle side is provided with the puncture needle handle.
This utility model is used for clinical, is used with vacuum test tube, and the opening part of vacuum test tube is provided with the rubber stopper of a sealing usefulness, and the opening of vacuum test tube is provided with a card medicated cap, and with the rubber stopper parcel within it.During use, earlier fixed cover is inserted the card medicated cap, hands of operator is taken vacuum test tube, and another hand-held blood taking needle punctures and adopts ware, when finding blood back is arranged, can push the puncture needle handle of puncture needle, penetrates soft material plug and rubber stopper successively, normally takes a blood sample.After finishing blood sampling when first vacuum test tube, when needing to change another vacuum test tube, with hand-held puncture needle handle pin is taken out backward, pass through rubber stopper, when the front end of syringe needle is retracted in the transparent soft material plug, again fixed cover is extracted and is inserted another vacuum test tube, with hand-held puncture needle handle puncture needle is pushed away forward then, after the front end of puncture needle is by the rubber stopper on the vacuum test tube, promptly take a blood sample.The through hole (being the front end of through hole) that joins with soft material plug rear portion is a bellmouth, helps puncture needle and penetrates the soft material plug vertically.This utility model can not produce that blood is wandered and handled easily.
