Description
Technical field
This utility model relates to medical inspection acquisition technique field, particularly relates to a kind of Multifunction blood sampler.
Background technology
Blood testing is an inspection of medical inspection section routine, can provide foundation by blood testing for the diagnosis of disease.First the blood of patient will be gathered before carrying out blood testing, existing blood sampling device generally adopts disposable harvester to gather blood, harvester is directly exposed in air behind Kaifeng, and the antibacterial in air easily enters into harvester, affects the accuracy of blood testing result; Existing harvester is gathering the phenomenon that blood backflow may occur in blood process simultaneously, brings unnecessary pain to patient; After having existing harvester generally blood collection is complete again, directly by the blood transfer in harvester in test tube or special blood vessel, harvester work completes and is treated as waste disposal, this not only needs a large amount of harvesters, test tube and blood vessel, increase cost, blood is easily subject to the interference of external environment in transfer process simultaneously, affects the accuracy of blood testing result.
Utility model content
This utility model object is exactly to solve the problem, and proposes a kind of Multifunction blood sampler.The deficiency that the application exists in actual use for existing blood collection device, use Modern mechanical design theory and theory, on the basis of original blood collection device, increase check valve, air filter and improve push-pull bar, thus solving the deficiency of existing blood collector existence.
To achieve these goals, this utility model adopts following technical scheme:
A kind of Multifunction blood sampler, comprises push-pull bar, piston, needle tubing, air filter, check valve and blood taking needle; Described piston is installed in needle tubing; Described push-pull bar and piston removably connect; Described needle tubing connects air filtration valve, check valve and blood taking needle successively.
Described push-pull bar one end is provided with handle, and the other end is processed with groove.
Screw thread is processed with in described groove.
One end face of described piston is provided with boss, and described boss is processed with external screw thread, for installing push-pull bar.
Described needle tubing one end is designed with door, prevents piston from coming off in needle tubing.
Described needle tubing outer surface is processed with graduation mark, for observing the amount gathering blood.
Described needle tubing outer surface is also provided with spacing collar, for limiting the position of needle tubing.
Described air filter one end is connected with needle tubing, and the other end is connected with check valve; Air filter can prevent from, in antibacterial in outside air, cell entry needle tubing, ensureing the accuracy of blood testing.
Described check valve one end is connected with air filter, and the other end is connected with blood taking needle; Described check valve can prevent the blood backflow in needle tubing.
After described blood sampler completes blood sampling, the push-pull bar in blood sampler, blood taking needle and check valve are unloaded from needle tubing successively, remaining needle tubing, piston and air filter form blood holder.
Described blood holder is placed on test tube rack by the spacing collar on needle tubing.
The beneficial effects of the utility model are:
This utility model is a kind of Multifunction blood sampler, for the deficiency that existing blood sampler exists, by design air filter on needle tubing, solves the impact of outside air on blood testing accuracy; By installing check valve on air filter, effectively solving the problem of needle tubing inner blood backflow; By push-pull bar, check valve and blood taking needle are designed to removably connect, push-pull bar in blood sampler, check valve and blood taking needle parts are unloaded successively, remaining needle tubing, piston and air filter are transformed into blood holder, not only can be cost-saving, and effectively avoid blood in transfer process, be subject to the problem of outside air pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model blood sampler;
Fig. 2 is the structural representation of this utility model blood holder;
Wherein, 1. push-pull bar, 11. handles, 12. grooves, 2. needle tubing, 21. doors, 22. graduation marks, 3. piston, 31. boss, 4. spacing collar, 5. air filter, 6. check valve, 7. blood taking needle.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, this utility model is described further:
As shown in Figure 1, a kind of Multifunction blood sampler, comprises push-pull bar 1, piston 3, needle tubing 2, air filter 5, check valve 6 and blood taking needle 7; Piston 3 is installed in needle tubing 2; Push-pull bar 1 and piston 3 removably connect; Needle tubing 2 connects air filtration valve 5, check valve 6 and blood taking needle 7 successively.
Push-pull bar 1 one end is provided with handle 11, and the other end is processed with groove 12.
Screw thread is processed with in groove 12.
One end face of piston 3 is provided with boss 31, and boss 31 is processed with external screw thread, for installing push-pull bar 1.
Needle tubing 2 one end is designed with door 21, prevents piston 3 from coming off in needle tubing 21.
Needle tubing 2 outer surface is processed with graduation mark 22, for observing the amount gathering blood.
