Abstract
The utility model discloses a lead screw liner motor sampling device for a blood cell analysis product. The device comprises a linear motor, a linear guide rail, a moving assembly, a swab and a sampling needle tubing which are sequentially connected. According to the lead screw liner motor sampling device, in the process that a blood sample is collected by a blood cell analyzer, the reliability and accuracy of the device can be improved, thus accuracy of data obtained by the blood cell analyzer is further improved, the quality of the whole machine is also stabilized and improved, and meanwhile the structure is simple.
Description
Technical field
The utility model relates to medical instruments field, specifically a kind of sampling device.
Background technology
At present, the sampling device of known blood cell analysis instrument is all to adopt motor to add belt usually, and the parts such as sampling probe form.During sample introduction, operation circuit drives belt after the motor rotation after controlling voltage to motor rotation, uses sample introduction needle to move up and down.But belt movement is after a period of time, can produce belt and extend and loss, and be difficult to while giving the descending puncture rubber stopper of sample introduction needle by, and position is inaccurate, cause difficulty to the reliable sample introduction of sample introduction needle (blood sample collection), easily cause data to be forbidden and cause erroneous judgement, so that malpractice occurring.
The utility model content
The purpose of this utility model is the deficiency existed for prior art, provide a kind of sampling device can pass through easily the rubber stopper on glass tube, and can carry reliable, stable, exactly the linear electric motors of the screw mandrel for the blood cell analysis product sampling device into blood sample after the long period running.
For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is a kind of linear electric motors of the screw mandrel for blood cell analysis product sampling device, comprises the linear electric motors, line slideway, motion assembly, swab and the sampling needle tubing that join successively.
The other limit switch that is provided with of described line slideway.
In the utility model, adopt linear electric motors, line slideway, the parts such as motion assembly, sampling needle tubing, swab and limit switch form (removing belt).When the needs blood sample collection, operation circuit sends pulse electrical signal to linear electric motors, makes straight-line electric arbor (screw mandrel) left rotation and right rotation, directly drives the motion assembly and moves up and down, and drives the sampling needle tubing and does corresponding moving up and down.Simultaneously by adjusting the position of the sampling needle tubing on the motion assembly, can solve the hole concentric problem of itself and swab, thereby avoid swab to leak.The pulse electrical signal sent by operation circuit is controllable, thereby guarantees that the sample introduction needle tubing moves up and down the accurate, reliable of position.
Beneficial effect: the utility model can improve its reliability, accuracy in the process of the blood sample collection of blood cell analysis instrument, thereby further improve the blood cell analysis instrument, obtains data accuracy, and overall mass is is also stabilized and increased, simultaneously simple in structure.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented take technical solutions of the utility model under prerequisite, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
As shown in Figure 1, a kind of linear electric motors of the screw mandrel for blood cell analysis product sampling device, comprise the linear electric motors 1, line slideway 3, motion assembly 4, swab 5 and the sampling needle tubing 6 that join successively, at the other limit switch 2 that is provided with of line slideway 3.
Claims (2)
1. the linear electric motors of the screw mandrel for a blood cell analysis product sampling device, is characterized in that: comprise the linear electric motors (1), line slideway (3), motion assembly (4), swab (5) and the sampling needle tubing (6) that join successively.
2. a kind of linear electric motors of the screw mandrel for blood cell analysis product sampling device according to claim 1, is characterized in that: the other limit switch (2) that is provided with of described line slideway (3).
