Description
Technical field
This utility model relates to medical apparatus and instruments, relates to a kind of hemostix of using from venous blood collection more specifically.
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 inconvenient operation can puncture blood sampling person's finger accidentally and cause infection, has potential safety hazard.For this reason, relevant technologies expert has invented a kind of new blood sampling support set, and this support set of taking a blood sample 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 blood sampling support set is provided with the card medicated cap at the opening of vacuum test tube, be provided with fixed cover on the card medicated cap, card medicated cap and fixed cover are taked tight inserting mode, can limit fixed cover and rock, and being provided with puncture needle in the fixed cover, the side of puncture needle also is provided with a puncture needle handle; In the operation of taking a blood sample, when finding blood back is arranged, can push the puncture needle handle of puncture needle like this, 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 collection support set 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 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.For this reason, the application's designer once improved this, at the fixed cover front end the transparent soft material plug of puncture needle was set, when needs are changed vacuum test tube, earlier hand-held puncture needle handle pulls back, and piercing needle is returned in the soft material plug problem thereby the solution blood flow falls.Need Artificial Control but the needle handle that will puncture pulls back, draw not in placely, still produce blood flow and fall; Be pulled through, piercing needle returns in the inner via hole, promptly produces blood flow and falls in the inner via hole, therefore, needs carefully operation, causes operation inconvenience, and blood sampling time prolongs.In addition, the soft material plug after, piercing needle advance and retreat resistance is big.
Summary of the invention:
The purpose of this utility model provides a kind of piercing needle advance and retreat distance of can controlling to the needs position, and the piercing needle resistance of advancing and retreat in the soft material plug is little, the hemostix of handled easily.
The purpose of this utility model can realize by following technical measures:
This blood sampling support set 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, connect puncture needle before the puncture needle handle, blood taking needle is connected with the puncture needle handle by flexible pipe, one strip shape gob is arranged on the sidewall of fixed cover tail end, this strip shape gob is communicated with strip gab, and the fixed cover front end is connected with the soft material plug of cavity.
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 taper; Anterior and plug rear portion is formed by connecting the soft material plug that is connected in fixed cover front end inboard by plug, or the plug of soft material plug is anterior joins with the plug rear portion, and filling in has inside boss in forward bottom surface ring week, and this boss matches with the groove of fixed cover front end; 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.
The soft material plug can be an integral body, because soft material plug (hollow) is made trouble, preferably divide two parts to make, promptly fill in anterior and the plug rear portion, plug front portion and plug rear portion can be same diameter, also can be to constitute the boss shape, material can adopt identical, also can be different, plug is anterior can to adopt the mode of closing sealing, the also optional mode that is glued at of squeezing of installing with the plug rear portion.
When this utility model is installed, the anterior fixed cover that inserts of the needle handle that will puncture, the hand part of puncture needle handle is divided and to be pushed into the top along strip shape gob, and the syringe needle of the puncture needle of this moment inserts and be arranged in the cavity of soft material plug by soft material plug rear end, is diverted to strip gab along lateral port again.During use, cooperate, earlier fixed cover is inserted the card medicated cap with vacuum test tube, hand-held blood taking needle carries out puncture blood collecting, when finding blood back is arranged, can push the puncture needle handle of puncture needle, penetrate the rubber stopper on soft material plug cavity front portion and the vacuum test tube successively, normally take a blood sample.After finishing blood sampling when first vacuum test tube, when needing to change another vacuum test tube, hand-held puncture needle handle pulls back to the strip gab end, the syringe needle of this moment is by rubber stopper on the vacuum test tube and soft material plug cavity front portion, just in time be in the cavity, again fixed cover is extracted and inserted another vacuum test tube, and then the operation of repetition front is taken a blood sample.The advance and retreat of puncture needle distance is limited by the length of strip gab, when not producing blood flow and falling, owing to the soft material plug is provided with cavity, the resistance of puncture needle in the soft material plug is significantly reduced, and handled easily has shortened blood sampling time.
