Description
Technical field
This utility model relates to a kind of sampled plasma device, belongs to technical field of medical instruments.
Background technology
Blood constituent comprises the components such as blood plasma, platelet, leukocyte, erythrocyte.Autologous platelet rich blood plasma is widely used clinically, and autologous plasma may be used for treatment of arthritis and promotes wound healing in a small amount.In medical industry, being separated blood constitutent, is very general and significant a kind of operation.But in the prior art, owing to there is the step of suction blood plasma after some plasma separating unit centrifugalize, add the risk that blood plasma pollutes.Some plasma separating unit is built-in with separation gel or separating medium, causes blood plasma to be likely mixed into foreign constituents, therefore, can produce potential safety problem, thus limit their Clinical practice.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of safety sampled plasma device high and easy to use.
For achieving the above object, this utility model takes following technical scheme: a kind of sampled plasma device, is characterized in that: it comprises a piston type needle tubing, a three-way valve and a blood taking needle; The fluid output port of described piston type needle tubing connects the first interface of described three-way valve, and the second interface of described three-way valve is connected with described blood taking needle, and the inside of described three-way valve is provided with the spool controlling its three interfaces and be connected.
The described first interface of described three-way valve is provided with female thread and matches with described piston type needle tubing, and described second interface of described three-way valve is provided with external screw thread and matches with described blood taking needle.
This utility model is owing to taking above technical scheme, it has the following advantages: 1, this utility model is owing to being provided with a piston type needle tubing, one three-way valve and a blood taking needle, one interface of the fluid output port connecting tee valve of piston type needle tubing, another interface of three-way valve is connected with blood taking needle, and this utility model structure is simple.2, this utility model can directly by the red blood cell component discharge piston type needle tubing after centrifugal by three-way valve, and change another blood taking needle of injection, thus can realize the autoinjector of blood plasma fast, this utility model is easy to use and safety is high.3, when this utility model uses, from collection blood, separated plasma to the injection of discharge red blood cell component laggard promoting the circulation of blood slurry, plasma fraction can be made not contact with external environment or material, avoid plasma fraction and pollute, thus can patient safety be ensured.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail.
As shown in Figure 1, the utility model proposes a kind of sampled plasma device, it comprises piston type needle tubing 1, three-way valve 2 and a blood taking needle 3.One interface 21 of the fluid output port connecting tee valve 2 of piston type needle tubing 1, another interface 22 of three-way valve 2 is connected with blood taking needle 3.The inside of three-way valve 2 is provided with the spool (not shown) controlling its three interfaces 21,22,23 and be connected.
In above-described embodiment, the interface 21 of three-way valve 2 is provided with female thread and matches with piston type needle tubing 1, and another interface 22 of three-way valve 2 is provided with external screw thread and matches with blood taking needle 3.
As shown in figs. 2 to 4, before use, in cylindrical shell 1, preset anticoagulant (not shown), prevents blood coagulation to this utility model, and the 3rd interface 23 of three-way valve 2 keeps closing simultaneously.During use, after extracting blood samples of patients 4, another interface 22 controlling three-way valve 2 is closed, and removes blood taking needle 3.Three-way valve 2, piston type needle tubing 1 that blood 4 is housed are put into centrifuge (not shown) jointly, controls centrifuge speed, realize the blood plasma 5 in piston type needle tubing 1 inner blood 4 and erythrocyte 6 layering.Then control erythrocyte 6 composition and discharge piston type needle tubing 1 along another interface 22 of three-way valve 2, the 3rd interface 23, enter be connected with three-way valve 2 for collecting in erythrocytic collecting bag (not shown).Then remove three-way valve 2 and erythrocytic collecting bag is housed, changing another blood taking needle 7 of injection.The blood plasma 5 left in piston type needle tubing 1 directly can carry out autoinjector.
The various embodiments described above are only for illustration of this utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
