Utility model content

Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of blood rheological instrument sampling needle and cleans device.

Technical solutions of the utility model are as follows: a kind of blood rheological instrument sampling needle cleans device, have and wash pin device, described pin device of washing is made up of medical plastic, conical bores and the drain pipe of lower vertical shape including top, the upper end of conical bores is uncovered, the inlet of cleanout fluid it is provided with on the sidewall of this conical bores, the lower end of conical bores connects with drain pipe, and the axial line of the axial line of conical bores and drain pipe is point-blank, inwall entire body at described drain pipe is provided with spiral helicine groove, and the separation of groove and depth ratio scope are 1-3.

Using above technical scheme, the pin device of washing being made up of medical plastic more has advantage on production cost, and can antirust corrosion-proof, more meet medical condition.Sampling needle moves along the axis of conical bores and drain pipe, when moving in conical bores and drain pipe, is cleaned by the cleanout fluid entered on sidewall.Either cleanout fluid passes through inlet, or is discharged by drain pipe, all by being arranged at acting on of the pump of the pipeline of inlet and the pipeline of drain pipe.Cleanout fluid is poured in conical cavity body by inlet, can rotational flow under inertia and action of gravity when that cleanout fluid flowing to.Entering into the cleanout fluid mid portion flow velocity in conical cavity body the fastest, conical bores edge, because resistance flow velocity is the slowest, can automatically form whirlpool, and circinate cleanout fluid fluid has bigger scouring force to sampling needle so that sampling needle is cleaned by cleaner.Meanwhile, on drain pipe pipeline, clean the cleanout fluid of sampling needle under the spiral groove positive action of suction pump and drain pipe inwall, liquid flow direction has been changed, formed revolving force, then drive the liquid in rotation of whole vertical portion to twist.In groove separation and ratio range that the degree of depth is 1-3 so that the effect of liquid in rotation twisting is more preferable.

This utility model make use of the setting of the spiral groove on conical bores and drain pipe so that cleanout fluid is that sampling needle is carried out by swirling, has corrosion-resistant, cleans great efforts, and cleaning speed is fast, and cleaning performance is good and prevents the beneficial effect polluted.

Further, the degree of depth of described groove is 1mm-2mm.As medical device, sampling needle is the most tiny a kind of implements, and the manufacturing washing pin device has also been to cooperate with sampling needle.Use the groove of the 1mm-2mm degree of depth, both met performance need, and also will not destroy the structural strength washing pin device.

Further, described groove is V-groove.Relatively rectangular channel and U-lag etc., V-groove has so that cleanout fluid less viscous beneficial effect in groove.

Beneficial effect: this utility model is novel, simple in construction, not only meet cleaning great efforts, cleaning speed is fast, good and the free of contamination effect of cleaning performance, also there is enforcement easily, economical and efficient a little, is coupled to cleanout fluid simultaneously again and enters into the situation of washer, and the moulding of change drain pipe upper groove and the degree of depth improve the effect of cleaning further.
