[specific embodiment]
Characteristic of the present invention and advantage will combine accompanying drawing to be elaborated through embodiment.
The present invention towards the medical worker in using the defibrillation monitor work process, can produce a series of event datas relevant with patient (as the chamber quiver, electric shock, medication, recovery or the like); Because of defibrillation belongs to the emergency treatment incident; When incident broke out, the medical worker often carried out quick diagnosis and treatment through clinical experience and real-time monitoring data, waited to treat or critical medical events tempus intercalare later; Such as the defibrillation therapy tempus intercalare; The medical worker can be through the data of device storage, and the rapid analysis process data is reached for next step treatment or does the purpose of diagnosis for the incident that possibly 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 is as shown in Figure 1, comprises memory element and waveform display unit, and said 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
| Event type | Explanation |
| The treatment Action Events | Refer to that the medical worker is through operating equipment, the incident of generation.Such as electric shock, medication incident. |
| The physiology alert event | Refer to patient vital signs parameter alert event.Such as the too high incident of heart rate. |
Data acquisition needs respectively three types of data to be stored,
The first kind is storage incident name encoding and time of origin, and memory space is main system memory, and is as shown in Figure 2, and the pathology affair storage comprises the coding of event date, time of origin and pathology affair.Figure is as shown in Figure 3 for its Stored Procedure.
Second type is first physiological parameter (the 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.Figure is as shown in Figure 5 for its Stored Procedure; 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 type 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.Figure is as shown in Figure 7 for its Stored Procedure; 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 grade); 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 through system clock, sets up the data directory logical table, and data are carried out association.Data association figure is as shown in Figure 8.
The medical worker analyzes pathology affair through the incident review function at the defibrillation therapy tempus intercalare.
Main operational steps is following:
1, the medical worker carries out classified browse through " incident review " menu to incident, analyzes pathology and event procedure, sees that its handling process is shown in figure 10 shown in the review of Fig. 9 incident:
When the medical worker need carry out labor to a certain specific incident, the pathology affair selected cell was chosen the incident that needs are analyzed according to medical worker's selection, in Fig. 9 incident is looked back, added shown in frame incident-" the electric shock incident ".After the selected incident, indexing units is according to Time To Event, and index internal memory trend storage list and waveform storage list carry out data compilation; It is the measured value and the time of origin thereof of first physiological parameter in the very first time section at center that the first physiological parameter acquiring unit is used to obtain with this time of origin, and it is illustrated in the trend viewing area; It is the measured value and the time of origin thereof of second physiological parameter in second time period at center that the second physiological parameter acquiring unit is used to obtain with this time of origin, and it is illustrated in the waveform viewing area.Said very first time section can be 60 minutes, and said second time period can be 2 seconds.
The waveform analysis device of physiological parameter can further include selected unit, the first navigation key input block, the first navigation key input processing unit of time and follows converter unit.
Time, selected unit was used under the state of activation of trend viewing area, confirming seclected time through positioned cursor; The said second physiological parameter acquiring unit also is used for being this seclected time that the measured value and the time of origin thereof of second physiological parameter in the certain hour section at center is illustrated in the waveform viewing area.
The first navigation key input block is used under the state of activation of waveform viewing area, receives the input of the navigation key of waveform viewing area; The first navigation key input processing unit is used for the input that receives according to the first navigation key input block, controls time and the measured value of second physiological parameter corresponding with this time on the abscissa of the said second physiological parameter acquiring unit conversion waveform viewing area; Follow converter unit and be used to follow the conversion of the time on the abscissa of waveform viewing area, control time and the measured value of first physiological parameter corresponding on the abscissa on the said first physiological parameter acquiring unit conversion trend displayed map with this time.Can also comprise the second navigation key input block and the second navigation key input processing unit, the second navigation key input block is used under the state of activation of trend viewing area, receives the input of the navigation key of trend viewing area; The second navigation key input processing unit is used for the input that receives according to the second navigation key input block, controls time and the measured value of first physiological parameter corresponding with this time on the abscissa of the said first physiological parameter acquiring unit conversion waveform viewing area.
Memory element comprises high-speed internal memory RAM and Compact Flash.
