Existing venous detaining needle is comprised of puncture needle, threeway indwelling casing tube, remaining needle and calparine cap.Remaining needle is mainly used in transfusion clinically at present, adopts venipuncture and fixing remaining needle, seals with calparine cap after transfusion is finished.Then be equipped with blood taking needle with vacuum test tube for venous blood collection and take a blood sample in blood vessel, blood sampling separates with transfusion to be carried out.Sometimes sterilization connects blood taking needle again and takes a blood sample to calparine cap after also remaining needle is fixing.Be divided into blood sampling, fix, sterilize, connect, take a blood sample, not only step is various, has increased medical personnel's workload, and easily pollution, and the connection blood taking needle has also increased the distance of vacuum test tube and venipuncture point, has reduced speed and the efficient of blood sampling; When removing blood taking needle, the blood of leaving in the blood collection connecting tube is not only the waste to blood, also can pollute.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of venous detaining needle of taking a blood sample is provided, and can be used in the again patient of blood sampling that should infuse, and features simple structure is easy to use, has saved the operating time.
According to the technical scheme that this utility model provides, the venous detaining needle that can take a blood sample mainly comprises threeway catheter block, indwelling needle catheter, puncture needle and Paracentesis needle holder, and threeway catheter block front end is provided with indwelling needle catheter, and the side is provided with the transfusion connectivity port.Be provided with metal voussoir and batching pig in the described threeway catheter block, puncture needle inserts in the indwelling needle catheter after passing metal voussoir and batching pig.Described puncture needle rear end connecting puncture needle seat, it is characterized in that: also comprise long duct, threeway union joint, blood sampling needle stand, calparine cap, needle tube sheath, flow-stopping clip and blood taking needle, the transfusion connectivity port is by long duct connecting tee union joint, one end of threeway union joint connects the blood sampling needle stand, connects blood taking needle on the blood sampling needle stand.The other end of described threeway union joint connects calparine cap.Described long duct is provided with flow-stopping clip.
Described blood taking needle outer wrapping one deck caulking gum.
Connecting needle tube boot on the described puncture needle.
Described threeway catheter block, long duct and threeway union joint internal chamber wall are provided with anticoagulant coatings.
Described Paracentesis needle holder is provided with the brake pad of projection.
Described threeway union joint outer surface is provided with the brake pad of projection.
Compared with the prior art this utility model has the following advantages:
This utility model is simple in structure, compact, reasonable; It is dual-purpose to infuse and take a blood sample, and has reduced equipment cost; Avoid blood residual, reduced the blood waste, also reduced pollution; Blood sampling speed is fast, and success rate is high; Easy and simple to handle, alleviated medical personnel's workload; Use safety, effectively avoid acupuncture injured.
