Description

Finger blood collection and storage device for blood morphology examination and PCR detection

Technical Field

The utility model relates to the technical field of medical equipment, specifically be used for blood morphology inspection and PCR detection indicate blood collection storage device.

Background

The blood cell morphology examination and the leukemia related gene detection are common methods for diagnosing blood system diseases, the sample source of the blood cell morphology examination is usually fingertip blood, and the sample source of the leukemia related gene detection is usually venous blood. Although these two items have been widely developed in the clinic, there still exists a certain inconvenience, mainly as follows:

(1) when a patient does two projects at the same time, venous blood and finger blood are generally required to be collected respectively, so that the treatment experience of the patient is influenced;

(2) when a patient is subjected to a blood cell morphology examination, fingertip blood is collected and immediately prepared. For non-hematologists, the quality of the samples to be inspected is often poor due to poor slide making level, and the accuracy of the results is affected. At present, two methods are commonly adopted for compensation, firstly, a patient is arranged to go to a designated hematology laboratory for blood sampling and film making, the method is mainly suitable for outpatients, and although the film making quality can be guaranteed, the method is not suitable for some inpatients or patients with unchanged action; second, venous blood was collected for examination and was prepared by a laboratory professional in the hematology department. Although the quality of the blood specimen can be guaranteed, the wound of the venous blood sampling is larger than the blood of the finger tip, meanwhile, a laboratory worker needs to open a blood sampling tube, a blood specimen is sucked by a liquid shifter and then smeared, the workload is increased, and aerosol pollution can be generated.
