Abstract
The utility model provides a kind of blood specimen collecting needle, including a blood transfusion pipeline, one first blood taking needle and one second blood taking needle, the both ends of the blood transfusion pipeline are connected with first blood taking needle and the second blood taking needle respectively, and a hard needle guard is arranged on first blood taking needle；A spiral expanding needle guard is arranged on second blood taking needle.The utility model advantage: by the middle part of rubber sleeve ontology be arranged spiral expanding section, operating force of second blood taking needle in plug can be greatly reduced, can very convenient Nurses execute-in-place.
Description
Technical field
The utility model relates to field of medical device, and spy is than being related to a kind of blood specimen collecting needle.
Background technique
With the continuous development of society and progress, the medical level of people also in the continuous improvement, various diseases quilt in succession
The mankind defeat, and during various disease treatments, blood sampling chemical examination is the measure of a routine.Blood specimen collecting needle is a kind of blood sampling
Common medical instrument, existing blood specimen collecting needle all have the first blood taking needle and the second blood taking needle, wherein the first blood taking needle is used
Blood is acquired in insertion human vas, the second blood taking needle realizes blood collection for being inserted into vacuum blood collection tube.In order to prevent
First blood-taking needle is to people or is contaminated, and hard needle guard can be all provided on the first blood taking needle；Due to carrying out every time
When blood sampling, it may be desirable to acquire more bottles of blood samples, blood splashing is to outside when replacing vacuum blood collection tube in order to prevent, second
A rubber sleeve can be all arranged on blood taking needle, in this way when carrying out blood specimen collection, so that it may which the second blood taking needle is directly pierced through into rubber
Glue housing is simultaneously inserted into vacuum blood collection tube, and when extracting the second blood taking needle, rubber sleeve can restore original appearance and make
Two blood taking needles are in the inside of rubber sleeve, come out to can effectively avoid blood splashing.But when specifically blood was collected,
Since the second blood taking needle needs the upper cover at the continuous top for piercing through rubber sleeve and vacuum blood collection tube, and existing rubber sleeve
It is all using straight tubular construction, therefore, when carrying out plug to the second blood taking needle, plug dynamics is larger, is unfavorable for operating.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of blood specimen collecting needle, can by the blood specimen collecting needle
Reduce plug dynamics when blood sampling.
The utility model is realized in this way: a kind of blood specimen collecting needle, the blood specimen collecting needle include blood transfusion a pipeline, one
First blood taking needle and one second blood taking needle, it is described blood transfusion pipeline both ends respectively with first blood taking needle and the second blood taking needle
It is connected, a hard needle guard is arranged on first blood taking needle；A spiral expanding needle guard is arranged on second blood taking needle.
Further, the spiral expanding needle guard includes a rubber sleeve ontology, and the middle part of the rubber sleeve ontology is equipped with one
Spiral expanding section.
Utility model has the advantages that can greatly be dropped by the way that spiral expanding section is arranged at the middle part of rubber sleeve ontology
Operating force of low second blood taking needle in plug, can very convenient Nurses execute-in-place.
Detailed description of the invention
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of structural schematic diagram of blood specimen collecting needle of the utility model.
Description of symbols:
100- blood specimen collecting needle, 1- blood transfusion pipeline, the first blood taking needle of 2-, the second blood taking needle of 3-, 4- hard needle guard, 5- spiral
Flexible needle guard, 51- rubber sleeve ontology, 511- spiral expanding section.
Specific embodiment
It please refers to shown in Fig. 1, a kind of preferred embodiment of blood specimen collecting needle 100 of the utility model, the blood specimen collecting needle
100 include a blood transfusion pipeline 1, one first blood taking needle 2 and one second blood taking needle 3, the both ends of the blood transfusion pipeline 1 respectively with institute
It states the first blood taking needle 2 to be connected with the second blood taking needle 3, a hard needle guard 4 is arranged on first blood taking needle 2, it is hard by this
Matter needle guard 4 can avoid the first blood taking needle 2 and stab people or be contaminated；A spiral is arranged on second blood taking needle 3 to stretch
Shortening set 5 can be prevented by the spiral expanding needle guard 5 when extracting the second blood taking needle 3 replacement vacuum blood collection tube (not shown),
Blood splashing is to outside.In the specific implementation, first blood taking needle 2 is for being inserted into human vas, to realize to blood sample
Acquisition；The blood transfusion pipeline 1 is used for the conveying of blood sample；Second blood taking needle 3 is for being inserted into vacuum blood collection tube, to realize
Collection to blood sample.
The spiral expanding needle guard 5 includes a rubber sleeve ontology 51, and the middle part of the rubber sleeve ontology 51 is equipped with a spiral
Telescopic segment 511.The utility model can be greatly reduced the by the way that spiral expanding section 511 is arranged at the middle part of rubber sleeve ontology 51
Operating force of two blood taking needles 3 in plug, can very convenient Nurses execute-in-place.
Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
Cover in the scope of the claimed protection of the utility model.
