Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of Multi-tube blood taking needle.
Background technology
In blood station or the work of blood internal medicine, often need sample of blood, drawn to carry out lab testing.Since blood sample when lab testing, require quantity different, often need to once gather the multitube blood sample.Existing blood taking needle all is single tube structure, behind the puncture vessel, can only constantly change vacuum test tube and take a blood sample, and blood sampling time is long, and that causes is painful large.And the blood taking needle occupation mode of present single tube structure is comparatively single, can't be applicable to more occasion.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of Multi-tube blood taking needle is provided, and saves blood sampling time, and is easy to use, practical, applied widely.
For solving above technical problem, the technical solution of the utility model is: a kind of Multi-tube blood taking needle, its difference is: it comprises blood taking tube, vein puncture needle head and pipe close piercing needle, described blood taking tube is the multitube structure, blood taking tube comprises a main pipe and at least two branched pipes, described main pipe afterbody is connected by joint with the branched pipe afterbody, every branched pipe head is provided with the pipe close piercing needle, every branched pipe middle part is provided with flow controller, and described main pipe head is provided with vein puncture needle head.
By above technical scheme, described pipe close piercing needle is connected separably with described branched pipe.
The contrast prior art, beneficial features of the present utility model is as follows:
1), this Multi-tube blood taking needle, can carry out continuously multitube blood sampling, save blood sampling time, easy to use;
2), this Multi-tube blood taking needle, the branched pipe in pipe close piercing needle and the blood taking tube is separable structure, the transfusion device of can directly transferring after complete of taking a blood sample reduces the misery of patient's secondary puncture;
3), this Multi-tube blood taking needle, in clinical position during Rescuing Critical Patients, the pipe close piercing needle can be separated with branched pipe in the blood taking tube, each branched pipe is connected many tube for transfusions simultaneously, thereby inputs different medicines for the patient sets up a plurality of venous channels;
4), this Multi-tube blood taking needle, can cooperate transfusion bag and blood taking tube when venous blood collection is practised, to use together, adopt the multitube structure can be for many people exercise of taking a blood sample simultaneously.
Description of drawings
Fig. 1 is this utility model embodiment overall structure schematic diagram;
Wherein: 1-vein puncture needle head, 2-pipe close piercing needle, 3-main pipe, 4-branched pipe, 5-joint, 6-flow controller.
The specific embodiment
By reference to the accompanying drawings this utility model is described in further detail below by the specific embodiment.
Please refer to Fig. 1, a kind of Multi-tube blood taking needle of this utility model, it comprises blood taking tube, vein puncture needle head 1 and pipe close piercing needle 2, described blood taking tube is the multitube structure, blood taking tube comprises a main pipe 3 and at least two branched pipes 4, and described main pipe 3 afterbodys are connected by joint 5 with branched pipe 4 afterbodys, and every branched pipe 4 heads are provided with pipe close piercing needle 2, every branched pipe 4 middle parts are provided with flow controller 6, and described main pipe 3 heads are provided with vein puncture needle head 1.
Concrete, described pipe close piercing needle 2 is connected separably with described branched pipe 4.
Use this utility model embodiment can carry out continuously the multitube blood sampling, save blood sampling time, easy to use; Pipe close piercing needle 2 wherein be separable structure with branched pipe 4 in the blood taking tube, the transfusion device of can directly transferring after complete of taking a blood sample, the misery of minimizing patient secondary puncture; And can be in clinical position during Rescuing Critical Patients, each branched pipe 4 in the blood taking tube and pipe close piercing needle 2 are separated rear many tube for transfusions that are connected simultaneously, thereby input different medicines for the patient sets up a plurality of venous channels; In addition, this utility model also can cooperate transfusion bag and blood taking tube to use when venous blood collection is practised together, and the multitube structure of blood taking tube can be for many people exercise of taking a blood sample simultaneously.This utility model is easy to use, and is practical, applied widely, has clinically preferably generalization.
Above content is the further description of this utility model being done in conjunction with concrete embodiment, can not assert that implementation of the present utility model is confined to these explanations.For the those of ordinary skill of the technical field under this utility model, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
