Abstract

The present invention is a system and a method for blood or urine sampling and sample-analysis, through a sampler that is a self blood-testing device or a urine-testing device. The system comprises a sampler, a transmission unit and an analysis unit. A patient may place a sampled blood drops on a sample strip and insert the strip into the sampler. The sampler may automatically prepare the sample and photograph it using a sample-preparation unit and a photography unit respectively. After the sample has been photographed, the resulting sample image may be transmitted to the analysis unit that may analyze the image through an image-processing algorithm. The analysis results may be automatically transmitted to the patient and to a medical authority, such as the patient'"'"'s physician, a nurse, a clinic and the like, for further analysis, decision-making and treatment.

an analysis unit that carries out automatic computerized analysis of the sampling outputting an analysis result,

wherein the results of said analysis unit are transmitted to the patient and to a medical authority for further medical analysis and decision making and

wherein said sample preparation unit comprises a smearing device and a staining device, respectively enabling smearing and staining of the sample preparing said sample to be photographed by said photography unit.

2. The system of claim 1, wherein the sample is a blood sample taken by the patient, and wherein said staining and smearing of said blood sample allows blood count related analysis.

3. The system of claim 1, wherein the housing unit includes an opening for inserting the sample strip, where the housing unit holds the sample strip while the sample is being prepared and photographed by the sampler.

4. The system of claim 1 farther enables sampling and sample analysis of the patient'"'"'s urine sample, by placing urine drops on the sample strip, wherein said staining and smearing of said sample allows cell count related analysis.

6. The system of claim 1, wherein the sampler automatically operates the smearing, the staining and the drying devices, once the sample strip is inserted into the housing unit.

7. The system of claim 1, wherein the smearing device comprises a smearing piece and a smearing base where the sample strip is placed on the said base and the smearing piece passes through the sample at least once and smears it.

8. The system of claim 1, wherein the preparation unit further comprises a drying device enabling drying of the sample, once said sample has been stained.

9. The system of claim 1, wherein the transmission device is a cellular phone that provides wireless network communication and the connector enables data transmission to at least one type of cellular phone.

10. The system of claim 1, wherein the transmission device is a computer that provides an internet network communication and the connector enables data transmission to a computer.

11. The system of claim 1, wherein the photography unit includes at least one camera and, wherein said camera further enables transmission of the photographed image of the sample.

12. The system of claim 10, wherein the camera is a solid-state detector that enables detection of sample images.

13. The system of claim 1, wherein the photography unit includes a camera and enables automatic transmission of the photographed image to the analysis unit.

14. The system of claim 1, wherein the analysis unit is a software application comprising at least one image processing algorithm.

15. The system of claim 13, wherein the said software application is seated at a remote computerized unit.

16. The system of claim 1, wherein the analysis unit is seated within the sampler device.

17. The system of claim 1, wherein the analysis is carried out through a processor enabling storing and analyzing the sample image.

18. The system of claim 16, wherein the processor is seated within the sampler device to allow automatic results outputting, presentation and transmission of the said results to the patient and to the medical authority.

19. The system of claim 1, wherein the transmission unit is integrated within the sampler.

21. The sampler of claim 19, wherein the sampler automatically operates the smearing, the staining and the drying devices, once the sample strip is inserted into the housing unit.

22. The sampler of claim 19 wherein the smearing device comprises a smearing piece and a smearing base where the sample strip is placed on the said base and the smearing piece passes through the sample at least once and smears it.

23. The sampler of claim 19 further includes a transmission unit that allows transmission of the photographed sample image to a remote analysis unit for image analysis.

24. The sampler of claim 22 further includes a receiver unit that enables receiving and representation of the analysis results.

25. The sampler of claim 23, wherein the receiver unit further includes a screen to allow representation of analysis results.

29. The method of claim 27, wherein preparing the sample is carried out through the steps of smearing the sample, drying the sample and staining the sample—

respectively, wherein the smearing, drying and staining of the sample is carried out in the preparation unit that is installed within the sampler.

30. The method of claim 27, wherein the analysis unit is a computerized unit that enables image processing of the sample image through at least one algorithm.

31. The method of claim 27, wherein the smearing device in the sampler comprises a smearing piece and a smearing base, where the sample strip is held by the said base and the said piece moves horizontally over the base to allow the smearing of the sample.

32. The method of claim 27, wherein the drying of the sample is made by a fan that is integrated within the sampler and the sample-preparation unit.

33. The system of claim 1, wherein the sample is taken by the patient and wherein said staining and smearing of said sample allows cell count related analysis.

5. (canceled)
