Abstract
The utility model provides a puncture device of a blood taking tube. The utility model is composed of a sleeve barrel, a pipe stopper puncture needle and a hemostasis sheath, wherein one end of the pipe stopper puncture needle is provided with a pipe stopper which is inserted with a blood taking flexible tube, and the other end is provided with a puncture needle head; the sleeve barrel is a tubular body which accords with a vacuum blood taking test tube, wherein one end of the sleeve barrel is sealed; the pipe stopper puncture needle is arranged in the middle of the sealed end of the sleeve barrel, the pipe stopper at one end of the pipe stopper puncture needle is arranged outside the sleeve barrel, and the puncture needle head at the other end of the pipe stopper puncture needle is arranged in the sleeve barrel; the hemostasis sheath is sheathed on the puncture needle head. The utility model has the advantages of safety protection for operators, convenient puncture and pollution prevention, and can be used for clinical blood taking.
Description
Technical field
This utility model relates to a kind of auxiliary device of clinical blood sampling, particularly can protect a kind of blood taking tube perforator of blood sampling personal security better.
Background technology
At present, the blood taking needle on the market mainly contains four classes, and type sleeve needle, the sleeve formula blood taking needle that is flexible coupling is put on the formula that is flexible coupling blood taking needle, sleeve needle, limit.This four classes blood taking needle is each has something to recommend him in the use, and the formula that is flexible coupling blood taking needle has good blood back form, and no rigid of transmission can connect fluid infusion, but blood sampling speed is slow, easily stab operator or patient in the use; Sleeve needle blood sampling speed is fast, prolong the traditional habit of having used blood collection needle, but do not have the blood back form, has rigid of transmission; The limit put type sleeve needle blood sampling speed fast, good blood back form arranged, prolong the traditional habit of having used blood collection needle, but have rigid of transmission, manipulate no suitable impetus in the process, easily sting perforating veins during replace tubes; The sleeve formula blood taking needle that is flexible coupling has good blood back form, no rigid of transmission, can connect fluid infusion, but because pipe close puncture place has increased individual sleeve, easily causes venipuncture needle to be deviate from from vein, and sleeve is reused and easily caused polluting.
Summary of the invention
This utility model is the deficiency at existing several blood taking needles, and a kind of safe, convenient, the antipollution a kind of blood taking tube perforator of puncture that can protect operator is provided.
The purpose of this utility model is achieved in that a kind of blood taking tube perforator, is made up of sleeve, pipe close puncture needle and haemostatic sheath, and wherein: one of described pipe close puncture needle is the pipe close of pegging graft with the blood sampling flexible pipe, and the other end is a piercing needle; Sleeve is the tubular body that adapts with the vacuum blood collection test tube, an end seals; The pipe close puncture needle is arranged on telescopic blind end middle part, and the pipe close of one head is positioned at outside the sleeve, and the piercing needle of other end is positioned at sleeve; Haemostatic sheath is enclosed within on the piercing needle.
The length of the piercing needle described in the above-mentioned blood taking tube perforator can be hidden in the sleeve piercing needle less than telescopic length.
Good between pipe close described in the above-mentioned blood taking tube perforator and the sleeve to be threaded to, make things convenient for production and processing.
After this utility model adopted said structure, telescopic use had guide effect, can effectively avoid the pipe close puncture needle to stab operator or patient, guarantees safe in utilization; The blood sampling flexible pipe can separate with the pipe close puncture needle, connects fluid infusion easily, reduces medical worker's workload.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, blood taking tube perforator of the present utility model is made up of sleeve 1, pipe close puncture needle 2 and haemostatic sheath 3, and one of pipe close puncture needle 2 is the pipe close 21 of pegging graft with the blood sampling flexible pipe, and the other end is a piercing needle 22; Sleeve 1 is the tubular body that adapts with the vacuum blood collection test tube, an end seals; Pipe close puncture needle 2 is arranged on the blind end middle part of sleeve 1, and the pipe close 21 of one head is positioned at outside the sleeve 1, and the piercing needle 22 of other end is positioned at sleeve 1; Screw thread is fixedlyed connected between pipe close 21 and the sleeve 1, and the length of piercing needle 22 is less than the length of sleeve 1, and haemostatic sheath 3 is enclosed within on the piercing needle 22.
When this utility model specifically uses, the pipe close 21 of 2 one of the pipe close puncture needles blood sampling flexible pipe 5 with band venous blood collection syringe needle 4 is linked to each other, get final product in the test tube plug insertion vacuum test tube of piercing needle 22 in will sleeve 1 during blood sampling by vacuum test tube.
