Embodiment
The embodiment to the pediatric examing table of the present invention is described in detail below with reference to accompanying drawings.
Generally, patient is safely can to rest or receive on one's sick bed treatment, is on the one hand because uninterrupted
Ground has medical personnel and carries out medical and nursing work, or has families of patients and look after for a long time, even in night, it is also possible to arrange special
The nursing staff of door retains one's original salary patient is nursed, shorten the unmanned nurse time of patient, another aspect also in that some
Patient still has certain ability to act, to oneself having carried out self specification, reduces the probability fallen from the bed.But, medical care
Personnel, families of patients or even the nursing staff retained one's original salary are artificial nurse after all, oneself also have the time had a meal, rested, it is impossible to right

Patient is to completely lose ability to act, for these patients, it is likely to once unintentionally stand up the hair for resulting in pendant bed event
It is raw.
In order to avoid patient falls the generation of bed event, in the prior art, hospital management side also takes much positive arrange
Apply, for example, transforming sick bed bed body, increase the height of guardrail, and set some geofences to set in sick bed bed body
Standby and emergence call equipment, to reduce the possibility that patient falls bed, the triggering device of pendant bed alarm is provided for patient, these transformations
Sick bed equipment afterwards reduces the generation that patient falls bed event to a certain extent.Meanwhile, hospital management side also takes
Measure, such as increase and the interaction and communication of families of patients, to reduce the time of the unmanned nurse of patient.
But, it is excessively simple that these existing hospital bed structural reforms make mechanism, because patient's pendant bed duration intervals are very of short duration, on
The detection and warning device accuracy of detection stated be not high, detection efficiency is low, the increase of guardrail height and nurses the increase of time only
The probability that patient falls bed can be reduced, without being avoided that the event of pendant bed occurs, most importantly, is lacked in the prior art to patient
Fall fast reaction measure and the fast reaction equipment of bed event, it is impossible to bed event is fallen to patient and carries out fast reaction, it is impossible in time
Patient body is quickly supported, leads to not the ill effect for avoiding patient from falling bed.
In order to overcome above-mentioned deficiency, the present invention has built a kind of pediatric examing table, can accurately and efficiently detect patient
Pendant bed event, can quickly be alarmed, additionally it is possible to patient is given first aid to using some emergency reaction equipment, so that effectively
Avoid patient by injury is hit, improve the intelligent level of sick bed.

In addition, the abbreviation of general packet radio service technology (General Packet Radio Service), he is GSM
A kind of available mobile data services of mobile phone user.GPRS can say be GSM continuity.GPRS is passed with the past continuous in channel
Defeated mode is different, is transmitted with package (Packet) formula, therefore the expense that user is born is with its data transmission list
Position is calculated, and non-usage its whole channel, in theory inexpensively.GPRS transmission rate can be promoted to 56 even 114Kbps.
GPRS is often described as " 2.5G ", that is to say, that this technology is located at the second generation (2G) and the third generation (3G) is mobile
Between mechanics of communication.By using untapped TDMA channels in GSM network, there is provided the data transfer of middling speed for he.GPRS breaks through
GSM nets can only provide the mode of thinking of circuit switching, only by increasing corresponding functional entity and to existing base station system
Carry out part transformation to realize packet switch, the input of this transformation is comparatively and little, but obtained user data rate
It is considerable.Moreover, because no longer needing intermediary's converter required for existing wireless application, connection and transmission all can
It is more convenient easy.In this way, user can both connect to the internet, the interactive communications such as video conference are participated in, and in same video signal net
The user of (VRN) on network, it might even be possible to without by dialling up on the telephone, and continue and network connection.
The communication mode of GPRS packet switches is in the communication mode of packet switch, and data are divided into the bag of certain length
(packet), each wrap before have a packets headers (address mark therein indicates that the packet is sent to where).Data transmit it
It is preceding and channel need not be allocated in advance, set up connection.But when each packet is reached, the information in datagram header
(such as destination address), finds an available channel resource and sends the datagram temporarily.In this transmission mode, number
According to the side's of sending and receiving cochannel between there is no the occupancy relation of fixation, channel resource can be regarded as being total to by all users
Enjoy and using.Because data service all shows a kind of paroxysmal business characteristic in most cases, to channel width
Changes in demand is larger, therefore is possible to better profit from channel resource using packet mode progress data transmission.Such as one is entered
The user that row WWW is browsed, the most of the time is in browse state, and the time for being really used for data transmission only accounts for very little ratio.
In this case according to the mode of fixed busy channel, it will cause the larger wasting of resources.
