具体实施方式 detailed description

[0017] 下面将参照附图对本发明的儿科检查床的实施方案进行详细说明。 [0017] below with reference to the drawings embodiments of the present invention, the pediatric patient table will be described in detail.

[0018] 一般情况下,病人是能够在病床上安全地休息或接收治疗,一方面是因为不间断地会有医护人员进行医护工作,或者会有病人家属长期照顾,即使在夜间,也可能会安排专门的护理人员带薪对病人进行护理,缩短了病人的无人看护时间,另一方面也是因为一些病人还是有一定的行动能力,对自己进行了自我规范,减少从床上坠落的概率。 [0018] In general, the patient is able to safely rest in bed or receiving treatment, partly because the medical staff have uninterrupted health care workers, patients or their families have long-term care, even at night, may also be the nursing staff paid special arrangements for patient care, shorten the time for patients unattended, on the other hand also because some patients still have some ability to act, carried out its own self-regulation, reducing the probability of falling out of bed. 但是,医护人员、病人家属乃至带薪的护理人员毕竟是人工看护,自己还有吃饭、休息的时间,无法对病人进行不间断、24小时的看护,因此,病人还是存在一定的无人看护时间,同时,还有一些病人是完全丧失行动能力,对于这些病人,很可能是一次无意的翻身就导致坠床事件的发生。 However, health care workers, and even the patient's family paid caregivers, after all, artificial care, they still have to eat, time to rest, the patient can not be continuous, 24-hour care, therefore, the patient is still some time unattended Meanwhile, there are some patients are completely incapacitated, for these patients, probably unintentionally turning on a falling bed leading to the event.

[0019] 为了避免病人坠床事件的发生,现有技术中,医院管理方也采取了很多积极的措施,例如,对病床床体进行改造,增加护栏的高度,以及在病床床体上设置一些越界报警设备和紧急呼叫设备,以减少病人坠床的可能性,为病人提供坠床报警的触发装置,这些改造后的病床设备在一定程度上减少了病人坠床事件的发生。 [0019] In order to avoid the occurrence of bed patients fall events, art, hospital management side has also taken a number of positive measures, for example, on the bed bed body transformation, increase the height of the fence, as well as set some in bed bed Cross-border police equipment and emergency call equipment to reduce the likelihood of a patient falling out of bed, providing patients falling out of bed alarm triggering device, after the transformation of these devices beds to some extent reduce the patient falling out of bed events. 同时,医院管理方还采取了一些措施,例如增加与病人家属的互动和沟通,以减少病人无人看护的时间。 Meanwhile, the hospital management side has also taken some measures, such as increased interaction and communication with the patient's family, in order to reduce the time the patient unattended.

[0020] 但是,现有的这些病床床体改造机制过于简单,由于病人坠床持续间隔很短暂,上述的检测和报警设备检测精度不高、检测效率低下,护栏高度的增加和看护时间的增加只能减少病人坠床的概率,而不能避免坠床的事件发生,最主要的是,现有技术中缺乏对病人坠床事件的快速反应措施和快速反应设备,无法对病人坠床事件进行快速反应,无法及时对病人身体进行快速支撑,导致无法避免病人坠床的恶劣后果。 [0020] However, these conventional bed transformation mechanism beds too simple, since the patient falling bed continuous interval is very short, the above-described detection and alarm device detects a high precision, low detection efficiency, increasing the height of the fence and an increase in nursing time can only reduce the probability of patients falling out of bed, but can not avoid falling out of bed incidents, most notably, the lack of prior art rapid response measures for patients falling out of bed events and rapid response equipment, not the patient falling out of bed fast event reaction, inability to support the patient's body quickly, making it impossible to avoid the adverse consequences of the patient falling out of bed.

[0021] 为了克服上述不足,本发明搭建了一种儿科检查床,能够准确、高效地检测出病人的坠床事件,能够快速进行报警,还能够使用一些应急反应设备对病人进行救护,从而有效避免病人受到撞击伤害,提高了病床的智能化水平。 [0021] In order to overcome the above disadvantages, the present invention is to build a pediatric examination bed can be accurately and efficiently detected event falling bed of the patient, the alarm can be quickly, it can also be used on emergency response equipment rescue the patient thereby effectively avoid being hit hurt patients, improve the intelligence level of the bed.

[0022] 图1为根据本发明实施方案示出的儿科检查床的结构方框图,包括病床和报警平台,所述平台包括重量变化率检测设备、无线充电设备和MSP430单片机,重量变化率检测设备用于检测病床上的负载重量变化情况,MSP430单片机与重量变化率检测设备连接,用于基于重量变化率检测设备的输出确定相应的报警策略。 [0022] FIG. 1 is a block diagram showing the structure of the pediatric patient table according to an embodiment of the present invention, including an alarm beds and a platform comprising a weight change rate detecting device, a wireless charging device and MSP430 microcontroller, weight change detection equipment changes in weight load on the detector bed, MSP430 microcontroller and the weight change rate detecting device is connected, for determining the corresponding alarm output strategy weight change rate detecting device based.

[0023]接着,继续对本发明的儿科检查床的具体结构进行进一步的说明。 [0023] Next, a specific configuration of pediatric continue examining table of the present invention will be further described.

[0047] 另外,通用分组无线服务技术(General Packet Radio Service)的简称,他是GSM 移动电话用户可用的一种移动数据业务。 [0047] Further, general packet radio service (General Packet Radio Service) is referred to, he is available to users of GSM mobile phones is a mobile data service. GPRS可说是GSM的延续。 GPRS can be said to be a continuation of GSM. GPRS和以往连续在频道传输的方式不同,是以封包(Packet)式来传输,因此使用者所负担的费用是以其传输资料单位计算,并非使用其整个频道,理论上较为便宜。 GPRS and past continuous channel transmission in different ways, based on the packet (Packet) type to transfer, so the cost is borne by the user for its data transmission per unit, rather than using the entire channel, theoretically cheaper. GPRS的传输速率可提升至56甚至114Kbps。 GPRS transfer rate can be increased to 56 or even 114Kbps.

[0048] GPRS经常被描述成“2.5G”,也就是说这项技术位于第二代(2G)和第三代(3G)移动通讯技术之间。 [0048] GPRS is often described as "2.5G", that is to say the technology positioned between the second-generation (2G) and third generation (3G) mobile communication technology. 他通过利用GSM网络中未使用的TDMA信道,提供中速的数据传递。 He by using TDMA channels in the GSM network is not used, there is provided in the data transfer speed. GPRS突破了GSM网只能提供电路交换的思维方式,只通过增加相应的功能实体和对现有的基站系统进行部分改造来实现分组交换,这种改造的投入相对来说并不大,但得到的用户数据速率却相当可观。 Breaking the GPRS network can only provide a way of thinking GSM circuit-switched, packet switching is achieved only by increasing the functional entity and the corresponding existing base station system part of the transformation, the transformation into such relatively not large, but to obtain the user data rate is quite impressive. 而且,因为不再需要现行无线应用所需要的中介转换器,所以连接及传输都会更方便容易。 Further, because the need existing wireless applications require mediation converter, the connection will be more convenient and easier to transport. 如此,使用者既可联机上网,参加视讯会议等互动传播,而且在同一个视讯网络上(VRN)的使用者,甚至可以无需通过拨号上网,而持续与网络连接。 Thus, the user can access the online, interactive communication such as video conferencing, and video users on the same network (VRN), and even without the need for dial-up Internet access, and continuous connection to the network.

[0049] GPRS分组交换的通信方式在分组交换的通信方式中,数据被分成一定长度的包(分组),每个包的前面有一个分组头(其中的地址标志指明该分组发往何处)。 [0049] GPRS packet-switched communication in the packet-switched communication system, the data is divided into packets of a certain length (packet), the front of each packet has a packet header (which indicates that the address mark where to send the packet) . 数据传送之前并不需要预先分配信道,建立连接。 Before a data transmission channel assigned in advance is not required to establish a connection. 而是在每一个数据包到达时,根据数据报头中的信息(如目的地址),临时寻找一个可用的信道资源将该数据报发送出去。 But when each packet arrives, the information (e.g., destination address) in the data header, the temporary channel to find an available resource sent the datagram. 在这种传送方式中,数据的发送和接收方同信道之间没有固定的占用关系,信道资源可以看作是由所有的用户共享使用。 In this type of transmission, there is no fixed relationship between transmission and reception occupy the same side of the channel data, channel resources can be considered as shared by all users. 由于数据业务在绝大多数情况下都表现出一种突发性的业务特点,对信道带宽的需求变化较大,因此采用分组方式进行数据传送将能够更好地利用信道资源。 Since the data traffic in most cases show a sudden operational characteristics, the demand for large changes in the channel bandwidth, so a packet data transfer mode will be able to better utilize channel resources. 例如一个进行WWW浏览的用户,大部分时间处于浏览状态,而真正用于数据传送的时间只占很小比例。 For example, a user of the WWW browser, the browser in the state most of the time, and the time actually used for data transfer only a small proportion. 这种情况下若采用固定占用信道的方式,将会造成较大的资源浪费。 In this case, if a fixed channel is occupied by the way, will result in a greater waste of resources.

[0050] 采用本发明的儿科检查床,针对现有技术无法为从病床上坠落的病人进行紧急救护的技术问题,通过加入高精度的多个检测设备进行检测结果综合分析,以有效判断病人是否发生坠落,还加入必要的报警设备进行报警,同时还加入了专门的应急反应设备以在病人坠落时进行紧急救护,从而体现了医院的人文救护精神,提高了病床的医护效果。 [0050] The present invention pediatric examination bed, the prior art for the technical problems can not be emergency care for the patient falling from the bed, by the addition of high-accuracy detection result of the plurality of detecting devices comprehensive analysis, in order to effectively determine whether a patient of fall, also add the necessary alarm equipment alarm, and also joined the special emergency response equipment for emergency care when the patient falls, which reflects the humanistic spirit of the hospital ambulance, the effect of improving the health care beds.
