Description

一种自动化止血按压器 技术领域
本发明涉及医疗辅助器械，尤其是涉及一种自动化止血按压器。
背景技术
在医疗实践中，静脉抽血是护理工作常规操作，静脉抽血拔针后因按压不当而引起穿刺点出血，癖斑等临床上时有发生，很多人认为静脉拔针是无须技术的操作，工作上疏忽，粗心，责任心不强，造成病人由于拔针不当而出现疼痛，出血癖斑等情况，也给病人心理上造成不愉快和对护理工作不满，容易造成纠纷，影响护理质量。按压时间不够及部位不正确会引起出血。一般拔针后要求局部按压3～5分钟，但护士拔针后大多数交病人或家属按压，没有说明按压时间，也没有再检查按压的部位是否正确，在按压过程中棉签也易偏移皮肤而出血。在静脉穿刺结束后，急需通过自动化方式，实现针眼按压的标准化、便捷化，减少医护工作者的工作压力，同时也避免患者出血等情况，从而遭遇二次医疗伤害。近年来，随着自动扎针机器人技术的逐渐成熟，大大提高了扎针过程的准确性，也缩短了扎针时间，但在扎针后的针眼止血按压方面，仍然需要手工进行完成，更多地依靠护士的经验和患者自身的配合程度，尤其是对于老年人或者行动不便的患者，按压止血往往存在各类困难。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种自动化止血按压器，实现静脉机器人穿刺后的自动止血按压。
本发明的目的可以通过以下技术方案来实现：
一种自动化止血按压器，包括支架模块、传动模块、手臂按压模块和手臂支撑模块，所述支架模块包括底座和环形轨道架，环形轨道架竖直设置在底座上，所述手臂按压模块和手臂支撑模块分别设置在环形轨道架顶部和底部，并且均可在环形轨道架内上下伸缩，所述传动模块包括两个对称设置在环形轨道 架两侧的传动单元，每个传动单元包括滑动块、第一连杆和第二连杆，所述滑动块设置在环形轨道架的轨道上，所述第一连杆的两端分别转动连接滑动块和手臂按压模块，所述第二连杆的两端分别连接滑动块和手臂支撑模块。
进一步地，所述手臂支撑模块包括复位弹簧和手臂支撑架，所述环形轨道架的底部设有安装槽，所述手臂支撑架的底端插入安装槽中，所述复位弹簧位于手臂支撑架下端的安装槽内，所述手臂支撑架转动连接两根第二连杆。
进一步地，所述手臂支撑模块还包括手臂托板，安装在手臂支撑架的最上端。
进一步地，所述手臂按压模块包括手臂按压架，该手臂按压架的最下端为按压部，所述环形轨道架的顶部设有通孔槽，所述手臂按压架的顶端穿过通孔槽，所述手臂按压架转动连两根接第一连杆。
进一步地，所述按压部上套有一次性使用的纱布套。
进一步地，所述手臂按压模块包括按压机构，安装在手臂按压模块的底部，该按压机构包括按压推杆、第一电机和超声波感应器，所述第一电机通过齿轮结构带动按压推杆上下移动，所述按压推杆的底端为吸盘，所述超声波感应器安装在按压推杆的一侧用于检测下方手臂是否在设定距离内。
进一步地，所述按压推杆和吸盘之间设有压力传感器。
进一步地，所述手臂按压模块还包括止血带替换单元，该止血带替换单元包括带轮和第二电机，所述第二电机连接带轮的转轴，所述止血带缠绕在带轮上，所述止血带替换单元上设有一个朝向按压推杆的出口槽，所述止血带的一端穿过出口槽，所述止血带由带保护膜的止血片连接而成。
进一步地，所述传动模块的滑动块位于环形轨道架的上半圆中。
进一步地，所述的底座采用中空三角形形状。
与现有技术相比，本发明具有以下有益效果：
1、本发明设计了由支架模块、传动模块、手臂按压模块和手臂支撑模块组成的自动化按压装置，其中的支架模块包括一个环形轨道架，传动模块是由连杆和滑动块组成；在使用过程中，患者只需要将手臂放置到手臂支撑模块上自然落下，手臂重力即可推动手臂支撑模块向下移动，连杆长度经过合理搭配，通过手臂重力推动手臂支撑模块逐渐下降的同时，上方的手臂按压模块在连杆 的拉动下产生比手臂支撑模块更大幅度的下降，实现对手臂的按压，即通过纯机械结构即可实现按压锁定，进行止血按压，而患者只需要放置手臂即可，操作快捷方便。
2、本发明的手臂按压模块还可以包括按压机构，设置额外的电机和按压推杆。当手臂按压模块下降后距离手臂仍然具有一端距离时，通过按压推杆实现二段式的推进按压；该结构可以使得按压推杆的行程较低，有利于结构的小型化和实现工作稳定性和灵敏度。同时，手臂按压模块还可以设置超声波感应器、压力传感器等，实现软件控制的自动化操作。
3、手臂按压模块还可以包括一个止血带替换单元，实现止血带的自动供给；本发明通过手臂按压模块的吸盘吸起止血带对针头处进行按压和贴合，减少了医护工作者的操作动作，避免了繁琐的消毒过程，保障医护人员及患者的卫生安全。

具体实施方式
下面结合附图和具体实施例对本发明进行详细说明。
下面结合附图和具体实施例对本发明进行详细说明。本实施例以本发明技术方案为前提进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于下述的实施例。
实施例一
如图1～3所示，本实施例提供了一种自动化止血按压器，包括支架模块1、传动模块2、手臂按压模块3和手臂支撑模块4。
支架模块1包括一个底座12和一个环形轨道架11，环形轨道架11竖直设置在底座12上，环形轨道架11内部为空腔，形成轨道；底座12采用中空三角形形状，内部被分割为两部分，在减少材料成本的同时，优化了承重结构，同时也提高了装置的一体性，更加美观。
手臂按压模块3和手臂支撑模块4分别设置在环形轨道架11顶部和底部，并且均可在环形轨道架11内上下伸缩。具体地说，手臂支撑模块4包括手臂托板43、复位弹簧41和手臂支撑架42。环形轨道架11的底部设有安装槽111，手臂支撑架42的底端插入安装槽111中，复位弹簧41位于手臂支撑架42下端的安装槽111内。由此手臂支撑架42可以在安装槽111内上下伸缩，复位弹簧41对其起到支撑的作用。手臂托板43设置在手臂支撑架42的最上端，手臂托板43的顶面为弧形，用于放置患者手臂。手臂按压模块3包括手臂按压架31，该手臂按压架31的最下端为按压部。环形轨道架11的顶部设有两个半圆的通孔槽112，手臂按压架31的顶端穿过通孔槽112。手臂按压架31的中间设有限位部，对其上移距离进行限位。
传动模块2包括两个对称设置在环形轨道架11两侧的传动单元。每个传动单元包括滑动块21、第一连杆22和第二连杆23。滑动块21设置在环形轨道架11的轨道上，并且位于环形轨道架11的上半圆中。第一连杆22的两端分别转动连接滑动块21和手臂按压架31，同时第二连杆23的两端分别连接滑动块21和手臂支撑架42，本实施例中的转动连接采用铰接。各个连杆的长度经过合理搭配，通过手臂重力推动手臂支撑架42逐渐下降的同时，上方的手臂按压架31在连杆的拉动下产生比手臂支撑架42更大幅度的下降，实现对手臂的按压。使用时，按压部上套有一次性使用的纱布套，便于及时替换。
本实施例的工作过程和原理为：患者首先将手臂穿过环形轨道架11，位于 手臂按压模块3和手臂支撑模块4之间，手臂伸直与两者都不互相接触，通过静脉穿刺机器人完成穿刺抽血。然后患者将手臂略微后移并且自然落在手臂托板43上，使扎针处位于手臂按压模块3的下方。在手臂重力的作用下，手臂支撑架42向下移动，并且通过连杆和滑动块21带动手臂按压架31向下移动。如图4可知，滑动块21下移过程中，使得两根第一连杆22的距离变大，由此第一连杆22带动手臂按压架31继续下降，使手臂按压架31下移的距离要大于手臂支撑架42下移的距离，从而实现了对手臂的快速按压止血。用户只需要保持手臂的放置即可确保止血按压，无需再进行常规的另一只手进行按压，非常便于行动不便或者老年人使用。
实施例二
本实施例的基本结构和实施例一相同，其区别点在于：手臂按压模块3包括按压机构32，安装在手臂按压模块3的底部，如图5和图6所示。该按压机构32包括按压推杆321、第一电机322和超声波感应器。第一电机322通过齿轮结构带动按压推杆321上下移动，按压推杆321的底端为吸盘321a，采用现有的真空吸盘。超声波感应器安装在按压推杆321的边上用于检测下方手臂是否在设定距离内。
本实施例的工作过程和原理为：使用时先在吸盘321a下吸取一张止血贴。当手臂按压模块3下降后，超声传感器响应并且开始监测。当超声传感器检测到与人体手臂达到一定距离时，第一电机322开始工作，驱动按压推杆321向下实现二段式的推进按压，将止血贴贴合在扎针处。在按压推杆321和吸盘321a之间还设有压力传感器，当达到设定压力后即控制第一电机322反转，并且关闭吸盘321a，使得止血带5按压在扎针处保持止血按压。该结构和传动模块2相互配合，可以使得按压推杆321的行程较低，有利于结构的小型化和实现工作稳定性和灵敏度。
实施例三
本实施例是实施例二的改进型，手臂按压模块3还包括一个止血带替换单元33，如图7所示。该止血带替换单元33包括带轮332和第二电机331。第二电机331连接带轮332的转轴，止血带5缠绕在带轮332上，止血带替换单元33上设有一个朝向按压推杆321的出口槽333，使得止血带5的一端穿过出口 槽333。止血带5为带保护膜的止血片连接而成，相邻的止血片为虚电连接。在出口槽333的下边还可以设置刀口。当一次按压工作结束后，第二电机331可以驱动带轮332，使止血带5伸出出口槽333。按压推杆321的吸盘321a启动吸住止血带5，然后在下移过程中，止血带5被出口槽333切割形成止血片，即为一个止血贴，实现了止血贴的自动替换。
以上详细描述了本发明的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此，凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
