Description

一种穿戴式防辐射支架 技术领域
本发明属于医疗防护装置技术领域，具体涉及一种穿戴式防辐射支架。
背景技术
核医学显像，根据显像要求(比如肾动态显像、肺灌注显像、双下肢深静脉显像、运动心肌显像、肺通气显像或者患者病情、行动不便、老年体弱、病情严重)需要工作人员床旁打针；核医学仪器操作人员，对不同患者进行检查时，需要床旁协助摆位、操作仪器；核医学护理人员进行病房床单、被褥等整理、床旁护理患者时；核医学医师进行服用131碘或者注射显像药物后患者的查体时；注射药物、患者摆位、病房整理、床旁查体均为近距离操作，需要工作人员穿戴铅衣、铅围脖、防护眼镜、一次性口罩和帽子，并且操作距离长、操作次数多。铅衣重量平均为5kg左右，并且一般穿脱需要其他人给予辅助。如果一直把铅衣穿在身上，会增加工作人员的负荷，大汗淋漓；如果在每次操作前穿戴防护设备，操作后脱去，那么一个上午，每个工作人员需要穿脱二十余次防护设备，这样会占用一部分时间，影响工作效率，并且总需要有其他人协助穿戴。
为了保证铅衣的使用寿命，在穿戴完毕后，如何正确保存放置也是很关键的一个环节。目前铅衣的保存主要为，脱下后进行悬挂保存。悬挂架可以固定在墙上，也可以专门放置一个悬挂衣架。但由于铅衣比较重，尤其是几件铅衣同时悬挂，会给墙壁增加承重负荷。并且，几件铅衣同时悬挂，重叠在一起，不容易保持铅衣的干燥。
工作人员穿戴防护设备进行注射药物、患者摆位、病房整理、床旁查体等 近距离操作时，通过佩戴铅围脖对颈部器官进行保护，但铅围脖的宽度仅够保护甲状腺，缺乏对于腮腺、颌下腺的保护；通过佩戴铅眼镜对眼睛进行辐射防护，但铅眼镜比较重，操作时间长时，鼻梁部和耳朵部位会有压迫感，并且低头操作时，铅眼镜容易下移，需要工作人员不时的上扶，有时候，还需要请其他人帮助上扶；近距离操作时，所佩戴的一次性医用口罩和帽子起不到辐射防护的作用，缺少头部头发、其他器官、面部及腮腺部位的防护。
发明内容
针对上述技术问题，本发明提供了一种穿戴式防辐射支架，该防辐射支架可承受防辐射服的重量，减轻医务人员的负担，无需他人协助就可完成穿戴，提高工作效率，同时也方便保存。
为了解决上述技术问题，本发明采用的技术方案是：
一种穿戴式防辐射支架，包括上支架、下支架和锁紧机构，所述上支架与下支架铰接，所述下支架底端固定有行走机构，所述锁紧机构包括棘轮和棘爪，所述棘轮固定在上支架上，且棘轮的旋转中心位于上支架与下支架的铰接中心处，所述棘爪通过弹簧与棘轮接触联接，所述棘爪铰接有滑块，并通过该滑块与下支架滑动联接，所述滑块联接有弹性件，所述锁紧机构还联接有踏板机构，所述踏板机构可拉动滑块或棘爪移动，并使弹性件产生势能，所述上支架和下支架上安装有防辐射服。
所述滑块上设有孔，并通过该孔套设在下支架上，所述弹性件一端与滑块连接，另一端与下支架联接。
所述下支架上设有凹槽，所述滑块安装在凹槽内，并与凹槽滑动联接，所述弹性件设置在凹槽内。
所述踏板机构包括上踏板和下踏板，所述上踏板和下踏板铰接，并形成夹角，所述上踏板通过绳索与滑块或棘爪联接，所述下踏板与下支架固定。
所述上支架和下支架为可调节伸缩杆结构。
所述防辐射服为防辐射铅衣。
所述行走机构为万向轮。
所述上支架上设有头罩支架，所述头罩支架上安装有铅玻璃防护罩。
所述上支架和下支架根据人体采用仿形设计。
所述锁紧机构外设有保护罩。
与现有技术相比，本发明具有的有益效果是：
上支架和下支架铰接，并且在上支架和下支架上安装有防辐射服，医务人员无需他人协助，可直接将防辐射服穿在身上。当医务人员弯腰时，可用脚踩动踏板机构，使棘爪与棘轮分离；上支架转动后，带动棘轮旋转，通过棘轮和棘爪的分离，实现上支架和下支架的角度变化。弯腰后，可将脚抬起，棘爪卡住棘轮，限制棘轮的转动，从而固定上支架和下支架间的角度。保证医务人员弯腰时，防辐射服的重量始终由上支架和下支架承受。通过防护头罩保护人体头部和面部。使用后，可将支架放置到固定位置，无需将防辐射服悬挂，便于保存，并且结构简单，操作方便。
附图说明
图1是本发明结构示意图；
图2是本发明锁紧机构结构示意图；
图3是本发明滑块结构示意图；
图4是本发明铅玻璃防护罩结构示意图；
其中：1为上支架，2为下支架，3为棘轮，4为棘爪，5为滑块，7为凹槽，8为上踏板，9为下踏板，10为万向轮，11为保护罩，12为绳索，13为头罩支架，14为铅玻璃防护罩。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至4所示的一种穿戴式防辐射支架，包括上支架1、下支架2和锁紧机构，上支架1与下支架2铰接，下支架2底端固定有行走机构。上支架1和下支架2上安装有防辐射服。使用时，医务人员直接将胳膊伸到防辐射服对应的袖口中，人体进入上支架1、下支架2和防辐射服组成的包围结构中，无需他人协助，就可完成防辐射服的穿戴。
当医务人员弯腰进行操作时，医务人员的上半身会带动上支架1旋转，上支架1上固定有棘轮3，棘轮3也随之发生转动；棘爪4通过弹簧与棘轮3接触连接，弹簧使棘爪4与棘轮3保持接触联接，未踩动踏板结构时，上支架1和下支架2的角度是固定的。当医务人员弯腰时，可用脚踩动踏板机构，将棘爪4与棘轮3分离，使弹性件产生势能。通过棘轮3和棘爪4的分离，棘爪4的活动不受限制，从而实现上支架1和下支架2的角度变化。
弯腰后，可将脚抬起，由于滑块5与下支架2滑动联接，弹性件的势能被释放，弹性件通过滑块5带动棘爪4移动，棘爪4再次卡住棘轮3，限制棘轮3的转动，从而固定上支架1和下支架2间的角度。因此，可保证医务人员弯腰 时，防辐射服的重量始终由上支架1和下支架2承受。上支架1和下支架2采用伸缩杆结构，根据医务人员的身材，对上支架1和下支架2做调整，以适应不同医务人员的使用需求。通过行走机构，可实现该支架的整体移动，行走机构可采用万向轮10、滚轮、或者类似结构。
滑块5与下支架2的滑动联接，可通过多种结构实现。滑块5上设有孔，通过该孔将滑块5套设在下支架2上，滑块5沿下支架2移动。当然，还可以在下支架2上设置凹槽7，将滑块5安装在凹槽7内，滑块5沿凹槽7移动，同样也可实现滑块5与下支架2的滑动联接。
踏板机构由上踏板8和下踏板9铰接组成，上踏板8和下踏板9铰接后，形成夹角。踏板机构通过下踏板9与下支架2联接。上踏板8通过绳索12与滑块5或棘爪4联接。绳索12也可以更换为杆件，杆件的一端与上踏板8铰接，杆件的另一端与滑块5或棘爪4铰接。
踏板机构也可只采用上踏板8，上踏板8与下支架2铰接；铰接后，上踏板8与水平面形成夹角。该防辐射支架可承受防辐射服的重量，减轻医务人员的负担，无需他人协助就可完成穿戴，提高工作效率，同时也方便保存。
上面仅对本发明的较佳实施例作了详细说明，但是本发明并不限于上述实施例，在本领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化，各种变化均应包含在本发明的保护范围之内。
