Purport of the present invention is to solve existing medical Avoirdupois monitoring bed and adds in bed, reduces the article such as medicated pillow, books, adjust comfort level or the Mobile sickbed of sick bed, the irregular change of gross weight is on the impact of patient's normal type monitoring on the monitoring bed that causes, a kind of medical Avoirdupois monitoring bed and bed patient's Avoirdupois monitoring method is provided, and realizes simultaneously the online remote monitoring to patient body weight.
For the present invention, the bed body of medical Avoirdupois monitoring bed itself can adopt the bed body of any pattern, for example the fixing bed body in bed angle, bed angle movably anterior, the rear adjustable of bed body, bed body lie by the bed body of position, this is chosen according to the actual needs.In order to realize that people, thing on the bed body are weighed, need to LOAD CELLS be set at the bed body, LOAD CELLS is arranged on the bed board of a body and transfers, therefore the reality of LOAD CELLS acquisition is the gross weight data of people, thing on the bed body, for those skilled in the art, how at the bed body LOAD CELLS being set, corresponding basic structure all should be known, and no longer tires out herein and states.
Referring to Fig. 1 (not comprising a body among the figure), gross weight data on the bed body that LOAD CELLS will monitor are inputted processing module of the present invention, therefore the gross weight data of LOAD CELLS collection are analogue signal, need to convert behind the digital quantity again input processing module to by AD converter.
The effect of processing module is the gross weight data that the Real-Time Monitoring LOAD CELLS gathers, under original state, processing module need to be positioned on the body to human body that the initial gross weight of thing gathers on the external crucible body, and this may comprise other beddings on bed board and the bed body and the gross weight of article; After human body is positioned on the body, according to the gross weight data of initial gross weight and Real-time Collection, can calculates the real-time weight data of human body on the body and monitor.When recording for the body weight data of initial gross weight and Real-Time Monitoring, can adopt the memory element in the processing module or store by EEPROM, simultaneously, processing module can also be finished functions such as the replacement of body weight data, repeated measure, those skilled in the art also knows this, does not tire out equally at this and states.
The irregular change of gross weight data is to the problem of patient's normal type monitoring on the bed body that mainly solves for the present invention, and the irregular change of gross weight data mainly comprises on the bed body:
1, owing to increasing, reducing increase, the minimizing that article on the bed body cause gross weight on the body, this moment processing module directly to the Monitoring Data of gross weight on the bed body, body weight change that can't the correct response patient;
2, the abnormal motion that the people wears the clothes, sitting is had a meal etc. on the bed body, monitoring bed front end adjusts to raise patient's shank or rear end adjustment so that patient can lie leans on, and the situations such as movement of monitoring bed, variation intermittently can occur to bed body pressure in human body on the bed body at this moment, so that the gross weight data that LOAD CELLS collects can occur to fluctuate frequently, and then having affected the monitoring of patient body weight, these data are not the variation of the real body weight of patient yet simultaneously.
Above-mentioned cognition be because, need to carry out at the monitoring bed patient of Avoirdupois monitoring, mainly be aged people, the patient of renal failure, the patient who suffers from diabetes and suffer from many Other diseases are arranged, much be to be in long-time bed mastery state among these people, they generally can not have larger motion at the bed body, are under normal circumstances to make gross weight data generation irregular change on the body.
Certainly; the irregular change of gross weight data may also have other some forms except two kinds of above-mentioned principal modes, such as patient's short time on the bed body normally from the bed situation; under spirit of the present invention, these versions all should be in the scope that the present invention asks for protection.
In order to solve the above problems, the present invention is provided with the maintenance module of weighing, and under the normal patient body weight monitoring state, it is operated in non-triggering state, the normal monitoring of medical Avoirdupois monitoring bed without any impact, is triggered it before the gross weight generation irregular change on the bed body.
After the maintenance module of weighing triggers, processing module can be suspended the real-time gross weight data that the monitoring LOAD CELLS gathers, even perhaps processing module continues the real-time gross weight data that the monitoring LOAD CELLS gathers, but keep the Monitoring Data after module triggers to ignore to weighing, only play record in order to the usefulness of in the future inquiry.
No matter which kind of mode of employing, after the maintenance module of weighing triggers, when the gross weight data are in the irregular change state on the bed body, namely the patient on the bed body or monitoring bed itself are under aforesaid several situation, at this moment, processing module locks the weight data of patient on the bed body, processing module will keep module to trigger the constantly weight data of human body weighing, keep the module releasing to trigger as weighing before, be the weight data of human body in the gross weight data irregular change state procedure, and carry out record with this weight data.In fact, when the gross weight data were in the irregular change state on the bed body, patient's body weight itself did not just change on the bed body, and the real in real time weight data of patient should remain unchanged originally, so aforesaid operations is not in-problem.
After the irregular change state of aforesaid gross weight data finishes, weigh and keep module to remove triggering, the monitoring of gross weight data on the bed body that processing module is recovered LOAD CELLS is gathered, namely recover the monitoring to the real-time weight data of human body, but after the different irregular change states that get the gross weight data finished, processing module need to be carried out different correcting process to data.
Because patient's weight data is to be positioned on the body on the external crucible body the initial gross weight data of thing by the real-time gross weight data of LOAD CELLS collection and human body to calculate on the bed body, so the actual needs correction is that human body is positioned on the body the initial gross weight data of thing on the external crucible body.For example, in aforesaid the 1st kind of situation, after the bed body increased or reduces article, it was to increase or reduced that human body is positioned on the body on the external crucible body the initial gross weight of thing actual, and need to revise this moment to initial gross weight.
Because before the irregular change state of gross weight data, processing module has recorded the weight data of patient on the external crucible body, therefore according to irregular change state finish time of gross weight data, namely weigh and keep module to remove the gross weight data of constantly LOAD CELLS collection of triggering, just can obtain current initial gross weight data, after renewal, the initial gross weight data of correction, just can recover the monitoring to the real-time weight data of patient on the bed body.And for aforesaid the 2nd kind of situation, because initial gross weight data do not change, therefore carry out zero correction and get final product.
In order to realize remote online the body weight of patient on the bed body is monitored, the present invention also comprises communication module, be delivered to remote monitoring equipment or far-end monitoring personnel place with the patient body weight information that processing module is monitored, communication module can be the interface module of wire transmission, for example the RS232 serial interface module; Also can be wireless transport module, for example bluetooth module and WIFI module.It will be appreciated by persons skilled in the art which type of communication module is set should process according to actual needs, also can adopt the combination in any mode of above-mentioned communication module, realize purpose of the present invention.
Simultaneously, because monitored patient generally is severe-Iy ill patients, for monitoring from the bed situation above-mentioned patient, the present invention goes back the disconnected module of occlusion body major punishment, the gross weight data that collect when LOAD CELLS are less than predetermined value and reach predetermined long time when lasting, predetermined value can arrange and be stored in according to the ABW of patient on the bed body in the memory module, and predetermined lasting duration then can be set to such duration 15-30 second, breaks to avoid that patient is produced erroneous judgement from bed information.In case Rule of judgment is reached, processing module is that the communication control module is transmitted patient from bed information to remote monitoring equipment or monitoring personnel, and monitoring bed place then can lead to buzzer and send simultaneously warning message.Far-end monitoring personnel can go to the monitoring bed to observe conditions, and are dangerous to avoid patient such as patient's accident to founder the lower generation of bed.And for short time of patient normally from the bed situation, then can be as mentioned before, adopt that triggering weighs keeps the mode of module, avoid unnecessary alarm behavior.
