Abstract
A blood gas analysis specimen mixer relates to the technical field of testing technology of hospitals and mainly resolves technical problems including that a fixing mechanism of an existing mixer can not be applied to a needle drum and the mixer is small in swing amplitude, difficult in changing the amplitude, speed and the like, thereby being difficult in satisfying requirements of mixing of gas blood analysis specimens. The blood gas analysis specimen mixer comprises a servo motor and a needle drum fixing frame fixed on an output shaft of the servo motor. At least one needle drum locating hole is arranged on the needle drum fixing frame. Compared with the prior art, the blood gas analysis specimen mixer has the advantages that the needle drum can not slide out of the needle drum locating hole during swing or rotation due to the fact that the needle drum fixing frame is adopted and the middle of the needle drum is fixed in the needle drum locating hole. The servo motor is adopted for driving. The needle drum can be swung or rotated according to requirements. The amplitude, speed, rotation speed and the like can be adjusted according to actual situations so as to meet the demand of mixing of the blood gas analysis specimens. Additionally, the blood gas analysis specimen mixer is simple in structure and less prone to faults.
Description
Technical field
The utility model relates to a kind of blood gas analysis sample vortex mixer.
Background technology
The laboratory of the control laboratory of hospital and medicine, chemical industry makes routine tests or when checking, usually sampling or the liquid sample that is mixed with is carried out necessary mixing and handles.At present, realize that the approach of liquid sample mixing mainly contains two kinds, a kind of is to wave mixing by hand, and another kind is to use the vortex mixer mixing.It is easy, quick, effective to wave mixing by hand, but mixing property is influenced by human factor directly.
Existing vortex mixer all is the vortex mixer that is used for test tube.Because the xsect of test tube is bigger, and test tube do not have lid sometimes, and the vortex mixer that therefore is used for test tube is just swung test tube usually gently, with invisible spectro liquid mixing.
Like the Chinese patent document, the patent No. is 99230390.7 disclosed liquid vortex mixers, and this device utilizes the rotation of eccentric roller and the swing by a small margin that produces mixes the bottling liquid sample.This technical pattern is simple, reliable, mixing property is good, can satisfy the mixing requirement of conventional liq sample.
But the amplitude of fluctuation of above-mentioned technology equals the eccentric throw of eccentric roller, and amplitude of fluctuation is little and non-adjustable, can not satisfy the requirement of high viscosity values liquid sample mixing, particularly can not satisfy the mixing requirement to blood preparation.Blood gas analysis sample (being blood) is contained in the syringe usually, because syringe is different with the test tube structure, the fixed mechanism that therefore is used for test tube is not suitable for the fixing of syringe.Secondly, the blood that the artery from the people that holds in the syringe extracts, its viscosity is higher; And the xsect of syringe is less, adopts the above-mentioned vortex mixer that is used for test tube, because its amplitude of fluctuation is less; And amplitude of fluctuation, speed etc. all are difficult to change, therefore are difficult to satisfy the mixing requirement of blood gas analysis sample.
Summary of the invention
The utility model technical matters to be solved provides a kind of blood gas analysis sample vortex mixer, and syringe can swung or rotate to this blood gas analysis sample vortex mixer as required.The technical scheme that adopts is following:
A kind of blood gas analysis sample vortex mixer is characterized in that: comprise servomotor, syringe fixed mount, said syringe fixed mount is fixed on the output shaft of servomotor, has at least one syringe pilot hole on the said syringe fixed mount.Earlier syringe is inserted in the syringe pilot hole, servomotor drives the rotation of syringe fixed mount through output shaft then; Perhaps servomotor drives the syringe fixed mount through output shaft and clockwise rotates an angle, then rotates counterclockwise an angle, goes round and begins again, and shakes the action of syringe as staff.Syringe inserts in the syringe pilot hole of syringe fixed mount, because the madial wall of syringe pilot hole can be close in the bigger place of external diameter, syringe middle part, friction force between the two can avoid syringe in swing or rotating process, to skid off from the syringe pilot hole.
For fear of the syringe landing, be equipped with rubber ring in said each syringe pilot hole.Because the friction force between test tube and the rubber ring is bigger, therefore make test tube rotate or swing in not rubber ring slip relatively.
The utility model beneficial effect against existing technologies is that owing to adopt fixedly syringe of syringe fixed mount, the syringe middle part is fixed in the syringe pilot hole, so syringe can not skid off from the syringe pilot hole in swing or rotating process; Adopt driven by servomotor, can swing or rotate syringe as required, the speed of the amplitude of swing, speed, rotation etc. can be regulated according to actual conditions, can satisfy the mixing requirement of blood gas analysis sample, and it is simple in structure, is not easy to break down.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the user mode reference diagram of preferred embodiment shown in Figure 1.
Embodiment
As shown in Figure 1, the blood gas analysis sample vortex mixer in this preferred embodiment comprises servomotor 1, syringe fixed mount 3, and said syringe fixed mount 3 is fixed on the output shaft 2 of servomotor 1, has 4 syringe pilot holes 301 on the said syringe fixed mount 3.
For fear of syringe 4 landings, also be provided with rubber ring 302 in the said syringe pilot hole 301.Because the friction force between test tube 4 and the rubber ring 302 is bigger, therefore make test tube 4 rotate or swing in not rubber ring 302 slips relatively.
As shown in Figure 2, introduce the course of work below:
At first, syringe 4 is inserted in the rubber ring 302 of syringe pilot hole 301, servomotor 1 drives 3 rotations of syringe fixed mount through output shaft 2 then; Perhaps servomotor 1 drives syringe fixed mount 3 through output shaft 2 and clockwise rotates an angle, then rotates counterclockwise an angle, goes round and begins again, and shakes the action of syringe 4 as staff.In the rubber ring 302 of the syringe pilot hole 301 of syringe 4 insertion syringe fixed mounts 3; Because the rubber ring 302 of syringe pilot hole 301 madial walls can be close in the bigger place of syringe 4 middle part external diameters, friction force between the two can avoid syringe 4 in swing or rotating process, to skid off from syringe pilot hole 301.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; Be all equivalents of being done according to the claim scope of the utility model, be the utility model claim scope and cover.
Claims (2)
1. blood gas analysis sample vortex mixer, it is characterized in that: comprise servomotor, syringe fixed mount, said syringe fixed mount is fixed on the output shaft of servomotor, has at least one syringe pilot hole on the said syringe fixed mount.
