Wound electronic medical record system

Methods and apparatus for storing and reviewing wound data are shown using a digital datasheet, or wound electronic medical record (WEMR). The WEMR is preferably presented via a single page containing all data that should be considered by a wound healing provider, as predetermined by protocol. This includes, but is not limited to, fields for: a digital photograph of the wound; a graph of the wound healing rate (length, width, depth and area over time); wound and other treatments including current systemic medications, along with a patient identifier and review / approval indicator. This may also include hematology and chemistry laboratory data; radiology and pathology images along with their associated reports; ambulation status and other history; and microbiology data including sensitivities. The WEMR is implemented via a wound database system, which includes templates and policies for rapid report generation and tools for protocol mapping. A particular WEMR page may be designed for electronic or paper review and approval by a treating physician, thus permitting comprehensive but efficient review of all relevant wound data, whether for a personal or remote consult, real-time or otherwise. When teaching or doing studies, patient identifier information can be masked while still enabling review of large but detailed data sets for a variety of wound and patient criteria.

Method and apparatus for performing platelet measurement

The present invention relates to a hematology instrument system that discriminates platelets from red blood cells, debris and other particles within a blood sample. The instrument system uses an optical trigger and collects data at optical sensor locations relative to a flow cell-illuminating laser beam's optical axis. An axial sensor measures axial light loss due to a particle in the flow cell's illumination aperture. In addition, the instrument system can include an RF unit generates electrical parameters, such as DC and RF parameters, within the flow cell. Blood specimens can be prepared with and without a sphering agent.

Consumable tube for use with a flow cytometry-based hematology system

The present invention is a flow cytometry-based hematology system useful in the analysis of biological samples, particularly whole blood or blood-derived samples. The system is capable of determining at least a complete blood count (CBC), a five-part white blood cell differential, and a reticulocyte count from a whole blood sample. The system preferably uses a laser diode that emits a thin beam to illuminate cells in a flow cell and a lensless optical detection system to measure one or more of axial light loss, low-angle forward scattered light, high-angle forward scattered light, right angle scattered light, and time-of-flight measurements produced by the cells. The lensless optical detection system contains no optical components, other than photoreactive elements, and does not include any moving parts. Finally, the system uses a unique system of consumable reagent tubes that act as reaction chambers, mixing chambers, and waste chambers for the blood sample analyses. The consumable tubes incorporate reference particles, which act as internal standards to ensure that the dilutions made during processing of the samples have been carried out correctly, and to ensure that the instrument is working properly. The present invention also relates to methods for using the system.

Method and staining reagent for staining hematology sample in an automated staining apparatus

InactiveUS6858432B2Reduce organic solvent concentrationImprove concentrationPreparing sample for investigationBiological testingMedicine.hematologyRomanowsky stain
Automated staining equipment that can mix reagents is used to spray a Romanowsky stain onto slide mounted specimens which are then briefly centrifuged. The centrifugation step removes excess stain leaving only a thin film. Depending on the time of the centrifugation step, most of the organic solvent and part of the water in the stain are evaporated by airflow through the equipment. This greatly accelerates the staining reaction and preserves water soluble structures such as the granules in basophilic leukocytes. For optimal performance, this staining procedure requires a thiazin-eosin stain with about 90% to about 40% organic solvent, such as methanol, and only about 10% to about 60% water. This is a unique staining reagent in Romanowsky staining.
