Abstract
The utility model discloses a vacuum blood sampler which comprises vacuum blood sampling pipe, a clamping cap, a fixed sheath, a puncture needle and a blood sampling needle, wherein the opening position of the vacuum blood sampling pipe is provided with a rubber stopper for seal; the clamping cap is arranged at the opening end of the vacuum blood sampling pipe, and the clamping cap encloses the rubber stopper; the inner part of the fixed sheath is hollow, and the fixed sheath is arranged on the clamping cap; the puncture needle is arranged in the fixed sheath; the blood sampling needle is connected with the puncture needle by a flexible pipe. When blood return is discovered, the puncture needle is pressed, the rubber stopper at the opening position of the blood sampling pipe is punctured, and thus, blood is sampled normally. The utility model has the advantages of simple and convenient operation and safe use. Even if a verdant operator can complete blood sampling.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of vacuum blood collector 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.
The innovation and creation content
The purpose of this utility model provides a kind of vacuum blood collector simple in structure, easy to operate, safe in utilization, with low cost.
For achieving the above object, this utility model is taked technical scheme: a kind of vacuum blood collector, and it includes: a vacuum test tube, its opening part are provided with the rubber stopper of a sealing usefulness; One card medicated cap, it is arranged on the opening of described vacuum test tube, and with described rubber stopper parcel within it; One fixed cover, its inner hollow is arranged on the described card medicated cap; 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.
In above-mentioned a kind of vacuum blood collector, described puncture needle side is provided with a puncture needle handle, and the sidewall of described fixed cover is provided with the elongated slot of ccontaining puncture needle handle.
In above-mentioned a kind of vacuum blood collector, described vacuum test tube is a glass tubing or plastic tube.
In above-mentioned a kind of vacuum blood collector, the center of described rubber stopper, about two sides is equipped with a groove.
This utility model is owing to take above design, it has the following advantages: 1, this utility model 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 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.2, in this utility model, in the center of rubber stopper, 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.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is for being provided with the cross-sectional schematic of puncture needle in the fixed cover in this utility model
The specific embodiment
As shown in Figure 1, a kind of vacuum blood collector, it includes: a vacuum test tube 1, its opening part are provided with the rubber stopper 2 of a sealing usefulness; One card medicated cap 3, it is arranged on the opening of vacuum test tube 1, and with rubber stopper 2 parcels within it; One fixed cover 4, its inner hollow is arranged on the card medicated cap 3, and fixed cover 4 is taked tight inserting mode with card medicated cap 3, can limit fixed cover 4 like this and rock; One puncture needle 5, it is arranged in the fixed cover 4; One blood taking needle 6, it is connected with puncture needle 5 by a flexible pipe 7.
As shown in Figure 1 and Figure 2, in the present embodiment, puncture needle 5 sides are provided with a puncture needle handle 51, and the sidewall of fixed cover 4 is provided with the elongated slot 41 of ccontaining puncture needle handle.Like this, when operation puncture needle 5 penetrates rubber stopper 2, only need to promote puncture needle handle 51 and in fixed cover 4, axially slide, penetrate rubber stopper 2 thereby drive puncture needle 5 along elongated slot 41.In addition, for convenience puncture needle 5 penetrates rubber stopper 2, and special about two sides respectively is provided with a groove 21 in the center of rubber stopper 2, and the greater than other parts that penetrated of rubber stopper 2 approaches like this, can reduce the resistance when penetrating.
In the foregoing description, vacuum test tube 1 is a glass tubing.
During use, earlier fixed cover 4 is inserted card medicated cap 3, the operator takes blood taking tube 1 on the other hand, and another hand-held blood taking needle 6 carries out puncture blood collecting, when finding blood back is arranged, can push the puncture needle handle 51 of puncture needle 5, punctures rubber stopper 2, normally takes a blood sample.
