[specific embodiment]
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
The present invention can produce a series of event datas relevant with patient towards the medical worker and (quiver as the chamber in using the defibrillation monitor work process, electric shock, medication, recover or the like), because of defibrillation belongs to the emergency treatment incident, when incident breaks out, the medical worker often carries out quick diagnosis and treatment by clinical experience and real-time monitoring data, to be treated or critical medical events tempus intercalare later, such as the defibrillation therapy tempus intercalare, the medical worker can be by the data of device storage, the rapid analysis process data is reached for next step treatment or does the purpose of diagnosis for the incident that may happen suddenly.
Patient is implemented the defibrillator of rescue or the inside of defibrillation monitor is provided with high-speed internal memory RAM and high capacity nonvolatile memory Compact Flash, can store lot of data.
The pathology affair analytical equipment comprises memory element and waveform display unit as shown in Figure 1, and described waveform display unit comprises pathology affair selected cell, indexing units, the first physiological parameter acquiring unit and the second physiological parameter acquiring unit.
Defibrillation monitor is in monitoring or therapeutic process to patient, and the medical events data and the Wave data that are produced all store in the memorizer of defibrillation monitor automatically.
Defibrillation medical events data owner will comprise pathology treatment incident (such as defibrillation discharge, the medication incident) and patient care alert event (such as patient arrhythmia-chamber incident of quivering).As shown in table 1 below.
Table 1
Data acquisition needs respectively three class data to be stored,
The first kind is storage incident name encoding and time of origin, and memory space is a main system memory, and as shown in Figure 2, the pathology affair storage comprises the coding of event date, time of origin and pathology affair.Its Stored Procedure figure as shown in Figure 3.
Second class is first physiological parameter (for example vital sign data of patient's on-line monitor, for example heart rate) and the time of origin that storage can be represented patient's physiological parameter trend, and memory space is a main system memory.As shown in Figure 4, memory contents comprises the measured value and the corresponding time of origin of first physiological parameter.Its Stored Procedure figure as shown in Figure 5, the measured value and the time of origin of continuous acquisition first physiological parameter in patient's emergency aid and treatment or monitoring process, be stored among the RAM, when new pathology affair takes place, set up pathology affair harmony in the exterior Trends Sheet logical address mapping table.
The 3rd class is storage and relevant second physiological parameter and the time of origin thereof of formation first physiological parameter, second physiological parameter can be continuous ECG ecg wave form or other physiological wave graphic data of monitor patients, memory space is non-volatile type memorizer (Compact Flash), as shown in Figure 6, memory contents comprises the measured value and the corresponding time of origin of second physiological parameter.Its Stored Procedure figure as shown in Figure 7, the measured value and the time of origin of continuous acquisition second physiological parameter in patient's emergency aid and treatment or monitoring process, be stored in the CF card, when new pathology affair takes place, set up pathology affair harmony in the exterior waveform table logical address mapping table.
Because of equipment adopts high-speed content and jumbo non-volatile CF card, above time of origin can be gathered and storage by level second.
When patient event took place, equipment main system processing unit (CPU) deposited event code, Time To Event (second level) in the Installed System Memory unit; The simultaneity factor cycle (second level) carries out internal memory to patient's physiological trend data and stores continuously, and memory contents is data and time (second level); System cycle deposits patient's Wave data and time in non-volatile type memorizer CF-Memory in addition, the line time labelling of going forward side by side.Wherein storing process is a major key by system clock, sets up the data directory logical table, and data are carried out association.Data association figure as shown in Figure 8.
The medical worker analyzes pathology affair by the incident review function at the defibrillation therapy tempus intercalare.
Main operational steps is as follows:
