Abstract
The utility model discloses a disposable collection needle capable of collecting multi-tube vein blood samples synchronously. The disposable collection needle is mainly formed by connection of the two ends of a blood drainage catheter with a vein infusion needle and pipe plug puncture needles respectively. A pipeline of the blood drainage catheter is additionally provided with more than one externally-connected pipe, and the pipe end of each externally-connected pipe is connected with one pipe plug puncture needle. An inner cavity of the blood drainage catheter is communicated with an inner cavity of needle pipes of the pipe plug puncture needles. The disposable collection needle is especially suitable for being used under the condition that the multi-tube vein blood samples of the same person need to be collected at the same time in the process of emergency care or health physical examination or hospitalization or outpatient service diagnosis and treatment when various check items need to be carried out at the same time, operation is simple and easy to realize, collection speed of the multi-tube blood samples is high, carrying contamination caused when one pipe plug puncture needle is used for collecting the multi-tube blood samples in the traditional operation process is reduced or even eliminated, therefore, accuracy of check results is guaranteed, work efficiency and blood collection quality are improved, practicability is high, and popularization and application prospects are broad.
Description
Technical field
This utility model relates to medical apparatus, the particularly disposable acquisition technique of venous samples can, but a kind of disposable needle collector of adopting of synchronous acquisition multitube venous samples can specifically.
Background technology
As everyone knows, to the collection chemical examination of human vein blood sample, be the important means of diagnosis disease.At present, the disposable needle collector of adopting of the venous samples can that medical profession is used, mainly connect the blood drainage conduit by venoclysis needle and the pipe close puncture needle forms.Wherein, venoclysis needle is provided with protective sleeve of syringe needle outward, and the pipe close puncture needle is provided with gum cover and protective jacket outward.Above-mentioned disposable detailed process of adopting the needle collector application is: by professional health care, personnel find venous patient accurately, and after plan blood drawing position carries out disinfection, intravenous infusion syringe is punctured into by the vein blood vessel of bleeder, by the syringe needle of pipe close puncture needle, directly puncture in corresponding " vacuum test tube " again.Like this by the venous blood of bleeder will the suction function in " vacuum test tube " under, by venous transfusion needle tubing, blood drainage conduit, pipe close puncture needle tubing, finally enter " vacuum test tube " to complete the collecting work of blood successively.As certain blood count person, in the time of need to gathering the multitube venous samples can in accordance with doctor's advice simultaneously, medical personnel gather during first " vacuum test tube " required blood volume, the pipe close puncture needle is extracted from this " vacuum test tube " gag, and puncture into second " vacuum test tube ", after collecting required blood volume, then the pipe close puncture needle is extracted from second " vacuum test tube " gag, and punctured into another " vacuum test tube ".The like, until gathered required a plurality of venous samples can pipe number, venoclysis needle could be exited from the vein blood vessel by bleeder.And due to different lab works require different, different vacuum test tubes (with pipe cover colouring discrimination it) material composition that must pre-install is also different, as be respectively the different compositions such as coagulant, same regimen acid salt (1:9 anticoagulated blood or 1:4 anticoagulated blood), heparin, edta salt, oxalates/sodium fluoride, or also can pre-install for hemoculture with the culture fluid that checks infected by microbes etc.The disposable blood taking needle now used only is connected with a pipe close puncture needle, when gathering the multitube blood sample, just inevitably the content of previous " vacuum test tube " can be carried and enters in the next one " vacuum test tube ", thereby cause occurring the assay of phase mutual interference.Therefore, the existing blood sampling speed of the blood taking needle device of prior art is slow, efficiency is low, easily produces weak points such as carrying pollutant, is problem demanding prompt solution in the industry.
Summary of the invention
But the utility model proposes a kind of disposable needle collector of adopting of synchronous acquisition multitube venous samples can, purpose is by existing disposable structure of adopting needle collector is improved, the collection requirement of fast and convenient to meet, pollution-free to assay, glitch-free synchronous multitube venous samples can.
Technical solution of the present utility model
This utility model mainly is comprised of venoclysis needle, blood drainage conduit, pipe close puncture needle; each is connected the two ends of blood drainage conduit with venoclysis needle, pipe close puncture needle; venoclysis needle is provided with protective sleeve of syringe needle outward, and the pipe close puncture needle is provided with gum cover and protective jacket outward successively.It is characterized in that, have additional more than one extension tube attached on the pipeline of described blood drainage conduit, the pipe end of each extension tube attached all is connected with the pipe close puncture needle, and the inner chamber of blood drainage conduit communicates with the inner chamber of pipe close puncture needle tubing by extension tube attached.
Further technical solution of the present utility model
Described extension tube attached is vertical configuration with the blood drainage conduit and is connected, and the pipe end of extension tube attached fixes and is connected with the pipe close puncture needle.
Outside blood drainage conduit between described extension tube attached and extension tube attached, be provided with packaged type choked flow folder.
The beneficial effects of the utility model
This utility model be particularly suitable for for same individuality emergency treatment, health examination, be in hospital or outpatient service diagnosis and treatment process in, need carry out multiple item inspection simultaneously, must gather the multitube venous samples can simultaneously situation use, and operation is simple, the speed that simultaneously gathers the multitube blood sample is fast, and reduce and even stopped in the traditional operation process, gather the pollution of carrying of multitube blood sample generation with one " pipe close puncture needle ", guaranteed the accuracy of assay, and blood sampling work efficiency and quality of blood drawn have been improved, practical, there is popularizing application prospect.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model (embodiment mono-);
The structural representation that accompanying drawing 2 is this utility model embodiment bis-;
The structural representation that accompanying drawing 3 is this utility model embodiment tri-;
The structural representation that accompanying drawing 4 is this utility model embodiment tetra-.
The specific embodiment
As shown in Figure 1,2,3, 4,
This utility model mainline transfusion needle 1, blood drainage conduit 2, pipe close puncture needle 3 form.Venoclysis needle is provided with protective sleeve of syringe needle 11 outward, and the pipe close puncture needle is provided with gum cover 31 and protective jacket 32 outward successively.
The embodiment mono-that Fig. 1 means, be on the pipeline of blood flow conduit 2, separately has additional three extension tube attached 4, and the pipe end of each extension tube attached all is connected with pipe close puncture needle 3.Outside blood drainage conduit between extension tube attached and extension tube attached, be equipped with packaged type choked flow folder 21.
