Description

一种胸壁负压支撑装置 技术领域
本发明涉及医疗结构技术领域，具体涉及一种胸壁负压支撑装置。
背景技术
“连枷胸”又名多根多处肋骨骨折，是一种胸部急性创伤的急危重症，其死亡率大约在25％左右，导致其致命的主要因素是纵膈摆动。
现在针对“连枷胸”的现场急救方法包括棉垫填塞、皮肤/肋骨外牵引以及气管插管，但是采用棉垫填塞的方式容易使病患造成压迫胸腔，进行皮肤/肋骨外牵引的过程中操作困难且容易使病患造成严重的疼痛感，同时采用气管插管的方式在现场进行急救时操作也比较困难。
发明内容
针对现有技术中所存在的不足，本发明的目的在于提供一种胸壁负压支撑装置，以解决现有技术中，对“连枷胸”进行现场急救的过程中操作复杂、容易对病患造成压迫胸腔或严重的疼痛感的问题。

说明书附图中的附图标记包括：塑性支撑本体1、导流槽2、负压抽吸器3、负压出气孔4、排气管5、贴壁敷料层101、第一海绵缓冲垫层102、可塑性金属网层103、第二海绵缓冲垫层104、可接触黏胶膜层105、条形导流主槽部201、导流支流槽部202、塑性固定套6、塑性顶块7、环形锁槽8、刚性紧固球9、环形气囊10、锁止杆11、锁止滚轮12、涨紧弹簧13、收线杆14、导向环15、牵引线16、密封活塞套17、牵引杆18、活塞块19、调节杆20、连通管21。
结合图1和图2，本发明实施例提出了一种胸壁负压支撑装置，包括用于密封贴合在胸壁外侧的塑性支撑本体1，所述塑性支撑本体1与胸壁外侧接触的一侧面中部开设有导流槽2，塑性支撑本体1远离胸壁外侧的一侧面上设置有负压抽吸器3，负压抽吸器3的进气口通过开设在塑性支撑本体1上的负压出气孔4来与导流槽2连通，负压抽吸器3的排气口连通有排气管5；其中，负压抽吸器3可以为带有电源的负压泵。
将本塑性支撑本体1形贴设在胸壁外侧，启动负压抽吸器3来将导流槽2内的空气或液体从负压出气孔4处抽入负压抽吸器3后从排气管5中排出，使塑性支撑本体1与胸壁外侧之间形成负压，从而使塑性支撑本体1紧密且密封的贴合在胸壁外侧上，进而使塑性支撑本体1在胸壁外侧形成一个外支架来模拟肋骨进行支撑，防止纵膈摆动且在现场进行救治操作过程中比较简单，且不会对病患造成压迫胸腔以及不会对病患造成二次损伤，大大减轻了病患的疼痛感。
如图3所示，根据本发明的另一实施例，所述一种胸壁负压支撑装置，还包括对塑性支撑本体1的结构优化，采用的塑性支撑本体1可以呈根据胸壁外形进行形变的平板状，塑性支撑本体1包括依次重叠固定连接的贴壁敷料层101、第一海绵缓冲垫层102、可塑性金属网层103、第二海绵缓冲垫层104以及可接触黏胶膜层105，贴壁敷料层101与胸壁外侧密封贴设。
其中贴壁敷料层101由可以接触皮肤的贴壁敷料构成，可塑性金属网层103为本塑性支撑本体1的支撑骨架，可塑性金属网层103可以由可塑性铝材加工而成的网状结构，能 够根据胸壁外形进行形变且具有一定支撑强度；第一海绵缓冲垫层102和第二海绵缓冲垫层104均通过海绵构成，具有一定的缓冲性能且形成粘接相连的单面胶；可接触黏胶膜层105由黏胶膜形成，可粘贴在皮肤上，使塑性支撑本体1能够粘贴在胸壁外侧。
如图2所示，根据本发明的另一实施例，所述一种胸壁负压支撑装置，还包括对导流槽2的结构优化，采用的导流槽2包括一端与负压出气孔4连通的条形导流主槽部201，条形导流主槽部201的每侧两端之间均通过多个导流支流槽部202连通，且条形导流主槽部201的每侧的多个导流支流槽部202在条形导流主槽部201外侧依次间隔布置。
本实施例中条形导流主槽部201的每侧的导流支流槽部202数量为两个，通过条形导流主槽部201和导流支流槽部202的分布方式是为了在负压抽吸器3启动来使导流槽2内形成负压时，贴壁敷料层101与胸壁外侧之间的负压分布区域比较合理，来使塑性支撑本体1能够紧密的贴设在胸壁外侧上来对胸壁外侧进行支撑。
其中，在条形导流主槽部201内沿其长度方向布置有内十字引流管(附图中未画出)，内十字引流管的一端与负压出气孔4连通，另一端与距离负压出气孔4较远的导流支流槽部202端部连通；内十字引流管的布置方式是为了使距离负压出气孔4较远的导流支流槽部202端部内的空气或压力能够快速通过内十字引流管导入负压出气孔4内，使导流槽2内在进行负压抽吸时更加的快捷。
如图4所示，根据本发明的另一实施例，所述一种胸壁负压支撑装置，为了方便将负压抽吸器3与塑性支撑本体1快速进行连接或拆分，在塑性支撑本体1远离胸壁外侧的一侧面上固定设置有一端为开口的塑性固定套6，负压抽吸器3的底部嵌入塑性固定套6内后通过连接在负压抽吸器3和塑性固定套6之间的可调紧固件进行固定；通过可调紧固件来快速的对负压抽吸器3与塑性固定套6进行固定连接或使其脱离连接，其调节方便、快捷。
其中，采用的可调紧固件包括在塑性固定套6内底部固定设置的塑性顶块7、在塑性固定套6内壁上沿其周向方向开设的环形锁槽8以及在负压抽吸器3外壁上呈环形布置的多个刚性紧固球9，负压抽吸器3外壁上还铰接有以负压抽吸器3为中心对称布置的两锁止结构，两锁止结构之间连接有位于负压抽吸器3外壁上部的调节牵引结构，调节牵引结构以转动方式来控制两锁止结构相向或相离运动。
将负压抽吸器3的底部嵌入塑性固定套6内后，负压抽吸器3的底部与塑性顶块7相抵，此时在调节牵引结构的转动下来使两锁止结构相离转动，两锁止结构的锁止端均转入环形锁槽8内，两锁止结构的锁止端均与环形锁槽8内壁相抵，同时多个刚性紧固球9均 与塑性固定套6开口处的内壁相抵，从而对负压抽吸器3与塑性固定套6之间进行多点定位固定，负压抽吸器3牢固的与塑性固定套6相连，便于负压抽吸器3能够稳定的进行使用；使调节牵引结构的反向转动来使两锁止结构相向转动，两锁止结构的锁止端均从环形锁槽8内移出，即可将负压抽吸器3的底部从塑性固定套6内抽出，方便、快捷。
如图4所示，根据本发明的另一实施例，所述一种胸壁负压支撑装置，为了进一步提高负压抽吸器3在连接时的稳定性，还包括在负压抽吸器3外壁上还固定套设有环形气囊10，环形气囊10上连通有控制其抽气或充气状态的抽吸调节机构，抽吸调节机构由调节牵引结构的转动方式来调节；且负压抽吸器3的底部嵌入塑性固定套6内后，环形气囊10夹设在负压抽吸器3和塑性固定套6内壁之间，在调节牵引结构的转动下来使两锁止结构相离转动过程中，对环形气囊10内进行充气，使环形气囊10涨紧在负压抽吸器3和塑性固定套6内壁之间，从而进一步提高了负压抽吸器3和塑性固定套6之间的连接稳定性，使负压抽吸器3在运行过程中更加稳定；在调节牵引结构的反向转动下来使两锁止结构相向转动过程中，对环形气囊10内进行抽气，环形气囊10被抽瘪，环形气囊10脱离对负压抽吸器3和塑性固定套6内壁之间的涨紧固定，以便于快速的将负压抽吸器3从塑性固定套6内取出。
如图4所示，根据本发明的另一实施例，所述一种胸壁负压支撑装置，还包括对每个锁止结构的结构优化，采用的每个锁止结构均包括一端与负压抽吸器3外壁铰接的锁止杆11，锁止杆11的另一端转动相连的锁止滚轮12，锁止杆11的中部与负压抽吸器3外壁之间连接有涨紧弹簧13，且锁止杆11倾斜向上布置，调节牵引结构与锁止杆11的中部相连。
其中，涨紧弹簧13的设计来进一步增加锁止滚轮12与环形锁槽8内壁之间的相抵力，锁止杆11的倾斜布置方式是为了方便在将负压抽吸器3嵌入塑性固定套6内的过程中，锁止杆11均向负压抽吸器3方向进行转动来避免锁止杆11对负压抽吸器3向塑性固定套6内的移动造成阻碍，当负压抽吸器3底部与塑性顶块7相抵后，锁止杆11均向远离负压抽吸器3的方向转动来使锁止滚轮12与环形锁槽8内壁相抵，对负压抽吸器3进行锁止固定；锁止滚轮12在使对负压抽吸器3脱离锁止固定状态的过程中，锁止滚轮12与环形锁槽8内壁滑动相抵，来使锁止滚轮12与环形锁槽8之间能够快速脱离连接。
采用的调节牵引结构包括转动设置在负压抽吸器3外壁上部的收线杆14以及在负压抽吸器3外壁下部上固定设置的两导向环15，每个导向环15内均滑动穿设有牵引线16，两牵引线16的一端均固定缠绕在收线杆14上，另一端与两锁止结构中的锁止杆11的中部一一对应相连。
转动收线杆14来对两牵引线16进行收线工作时，使两锁止杆11均向靠近负压抽吸器3的方向进行转动，两锁止杆11相向转动，来使锁止滚轮12从环形锁槽8内移出，便可将负压抽吸器3从塑性固定套6内抽出，使塑性固定套6与负压抽吸器3脱离连接；将负压抽吸器3的底部嵌入塑性固定套6内后，负压抽吸器3底部与塑性顶块7相抵，反向转动收线杆14，收线杆14对两牵引线16进行放线工作，来使两锁止杆11均向远离负压抽吸器3的方向进行转动，两锁止杆11相离转动，来使锁止滚轮12转入环形锁槽8内与环形锁槽8内壁相抵。
如图4所示，根据本发明的另一实施例，所述一种胸壁负压支撑装置，还包括对抽吸调节机构的结构优化，采用的抽吸调节机构包括固定设置在负压抽吸器3外壁上部的密封活塞套17以及在收线杆14端部的偏心位置转动连接的牵引杆18，密封活塞套17内滑动设置有活塞块19，活塞块19的一侧固定连接有从密封活塞套17自由穿出的调节杆20，调节杆20置于密封活塞套17外的一端与牵引杆18远离收线杆14的一端转动且滑动相连，密封活塞套17远离调节杆20的一侧通过连通管21与环形气囊10连通。
转动收线杆14来对两牵引线16进行收线工作时，牵引杆18通过调节杆20来使活塞块19在密封活塞套17内滑动，使连通管21内形成抽吸力，从而将环形气囊10内的气体抽入密封活塞套17内，使环形气囊10被抽瘪，环形气囊10脱离对环形气囊10脱离对负压抽吸器3和塑性固定套6内壁之间的涨紧固定；反向转动收线杆14来对两牵引线16进行放线工作时，牵引杆18通过调节杆20来使活塞块19在密封活塞套17内反向滑动，活塞块19将密封活塞套17内的气体压入连通管21内后导入环形气囊10内，对环形气囊10进行充气，环形气囊10涨紧固定在负压抽吸器3和塑性固定套6内壁之间。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
