Description

粉末喷射方法及其装置 技术领域
本发明涉及一种粉末喷射方法，尤其涉及一种以气流带动粉末喷出，以应用于对创伤处实现止血，以及适用于该方法的装置。
背景技术
目前对于外伤或手术所致的创伤出血，不论采用何种止血技术，均离不开“压迫止血”的常规手段。常见的如：体外创伤使用的创可贴，以及各种手术中使用的止血海绵、止血微球、止血医用膜和无纺工艺制成的止血纱等。这些止血技术虽然有效提高了止血效率，但都必须先压迫一段时间后再将外力撤除，并观察创伤处是否仍有出血点。如仍有出血，则需继续使用止血剂，并再次压迫，直至达到止血。不仅操作繁复，依赖于人为判断，对于深层实质脏器和腔道深层创面的止血难以准确操作，造成止血困难，尤其是对这些部位或组织需长时间局部压迫而止血，不利于创伤的后期愈合。如：鼻窦或鼻腔，目前通常采用膨胀止血海绵，止血不易彻底，需压迫24小时后观察无出血再取出止血海绵。患者鼻部肿胀、呼吸道不畅，也造成手术及时止血困难，患者生存质量差，24小时观察并需第二次取出，增加医务工作者的工作量。
止血凝胶的出现，使得创伤止血得到了改善。但对于出血量较大的创口，止血凝胶难以在短时间内粘附于创口，难以实现及时止血的目的。
市场上，也有以喷雾方式将药剂喷于伤处的产品，这种喷雾方式的目的是均匀喷撒粉剂方式并不是一种止血方法。如：云南白药气雾剂，其主要用于扭伤，对于搓伤和刀伤等仍有必要采用粉剂止血(根据气雾剂使用说明书)。
发明内容
本发明的一个目的在于提供一种利用气压喷射粉末的装置，以便于将止血 剂直接作用于组织创面或创口，实现及时止血。
本发明的另一个目的在于提供一种气压喷射装置在创伤止血中的应用，以便于对各种组织或器官创伤进行可视下止血，去除了压迫止血的常规操作模式。
本发明的再一个目的在于提供一种粉末喷射方法，以气流带动粉末喷出，用于对创伤处实现止血。
本发明采用的技术方案如下：
一种粉末喷射方法，将装填有粉末的容置腔与压力气源连通，使气体进入容置腔，气体推动粉末经由与容置腔连通的喷射导管喷出。
另一种粉末喷射方法，将装填有粉末的容置腔与压力气源连通，使气体经导管进入容置腔，将置于容置腔内的粉末从腔底由下至上推动，经与容置腔连通的喷射导管喷出。
为有利于上述方法对创伤止血目的的实现，即将装填有止血剂的容置腔与压力气源连通后，气体推动止血剂经由与容置腔连通的喷射导管喷出，喷射导管出口处的压强为0.02Kpa～50Kpa，如：但不仅限于0.02Kpa～0.1Kpa、0.1Kpa～10Kpa或0.1Kpa～50Kpa。
在应用中，将喷射导管出口正对创伤处，使粉末(如：止血剂)作用于创伤表面的同时，受到压力恒定的和可持续的气压作用，实现对各类创伤表面实施可视下的止血。
创伤是受作用力所造成的组织或器官的破坏，包括创口和创面。
对于不同组织或器官的创伤，本发明提供的方法可以通过阀门或压力调节装置调节压力气源的压力，以根据不同组织及器官的组织结构不同，适应止血要求。如：鼻腔或鼻窦组织，喷射导管出口处的压强为0.02Kpa～0.3Kpa或0.3Kpa～2Kpa；再如：脑组织，喷射导管出口处的压强为0.02Kpa～0.3Kpa或0.3Kpa～0.8Kpa；又如：颅骨，喷射导管出口处的压强为0.3Kpa～0.8Kpa或0.8Kpa～10Kpa，又如：表皮组织、皮下组织，喷射导管出口处的压强为0.02Kpa～0.3Kpa或0.3Kpa～2Kpa，胸腔及胸腔内脏器、肝脏及腹腔内脏器、肾脏及泌尿系统脏器其压强为0.02Kpa～0.3Kpa或0.3Kpa～5Kpa，又如：动脉止血， 喷射导管出口处的压强为0.3Kpa～1Kpa或1Kpa～50Kpa；以及静脉止血时，喷射导管出口处的压强为0.02Kpa～0.8Kpa或0.8Kpa～20Kpa。
在应用中，喷射导管出口离创伤表面0.5～1.5cm或1.5cm～2cm。作为止血剂的粉末为止血粉或止血微球，如：发明专利ZL200610024198，可受气流压力为30Kpa～400Kpa的气流推动，并作用于各种不同组织及器官的创伤处(如：创口和创面的表面)。根据对各种不同组织或器官的创伤止血所能承受作用力的不同，调节并应用不同压力的气流压。

具体实施方式
以下结合附图详细描述本发明的技术方案。本发明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精神和范围，其均应涵盖在本发明的权利要求范围中。
图1和图2为本发明一种喷射式创伤止血装置一实施方式，该装置包括止血剂容器1、作用导管2、通气开关3、通气连接管4和外壳体5。止血剂容器1包括入口11，出口12、加料口13和本体14，入口与通气连接管4的一端连通，另一端111的端面朝向本体14的底面。作用导管2的一端为出射端，另一端与出口12连通。
通气开关3是一个压力气源的压力和流量调节装置，以可调的方式控制压力气源，使喷射导管出口处的压强为0.02KPa～0.1KPa或0.1KPa～50KPa，且保持气压恒定和持续。本实施例中，包括压块31、弹簧32、压板33和按压件34，弹簧套设于按压件，压块31设于按压件一端，且与压板33之间留有间隙35。通气连接管的管体41设于间隙35内，且其一端与入口11连接。
使用时，将通气连接管与压力源(如：医院中央供氧系统输出端(400KPa)、医用氧气的气体钢瓶或压缩空气)连接，使具有压力的气体经通气连接管连接的入口处进入止血剂容器内腔，经由另一端的端面喷出后，推动止血剂向出口运动，并经与出口连通的作用导管而将止血剂送出，即可使止血剂直接作用于创伤表面，通过调节气压即可对创伤表面施加恒定的作用力。
图3为本发明一种创伤喷射式止血装置一实施方式，该装置包括止血剂容 器1、作用导管2、通气开关3、通气连接管4、外壳体5和定位件6。止血剂容器1包括入口端11，出口端12、加料口13和本体14，本体置于外壳体5的容置腔内，其入口端与通气连接管4的一端连通，另一端的端面朝向本体14的底面。
作用导管2包括管体21、端面22、第一弹簧23，第一弹簧23套设于管体21，端面22与出口端配合，使管体内腔211与出口端连通。第一卡扣24套设于端面处的管体端，第一弹簧一端与第一卡扣相抵触，其上第一卡钩241设于出口端上方。
通气开关3是一个压力气源的压力和流量调节装置。本实施例中，包括压块31、弹簧32、压板33和按压件34，弹簧套设于按压件，压块31设于按压件一端，且与压板33之间留有间隙35。通气连接管的管体41设于间隙35内，且其一端与入口端11连接。
定位件6包括压杆61、第二弹簧62和连接头63。连接头设有连接腔体631，分别与入口端和管体连通，第二弹簧套设于压杆。第二卡扣64套设于连接头，其上第二卡钩641设于入口端上方。
使用时，将止血剂容器由容置腔放入，并下压。使第一卡扣和第二卡扣受压并后退，并分别使第一弹簧和第二弹簧弹性形变。待止血剂容器完全置入容置腔，第一卡扣和第二卡扣分别受第一弹簧和第二弹簧作用回复，其上第一卡钩和第二卡钩分别位于出口端和入口端上方而使止血剂容器固定，止血剂可以从加料口加入。
如图4所示，其提供了另一种用于创伤止血装置的实施方式，其具有一个容器100，用于容纳止血剂，还具有阀门300，以用于控制外接压力源与容器100连通或断开。本实施例连通件200为三通件，分别与容器100、阀门300和作用导管400连接。作用导管400的出射端折弯形成弯折部410，以利于止血剂作用于创伤处。
如图5和图6所示，阀门300包括阀体310、阀杆320、第三导管330、弹性部件340和锁扣件350。阀杆320设于阀体310的容置腔312内，并相对于阀 体枢轴转动。锁扣件350通过阀体上的通孔311(参见图7)穿设于阀体310，而与阀杆320的一端相抵，以限制阀杆320相对于阀体310枢轴转动的范围。第三导管330一端与第一导管230连接，另一端与外接压力源(未示出)连接。弹性部件作用于阀杆，使得施加于阀杆320的作用力撤销后，第三导管330受阀杆的作用而被阻截(参见图7)。
结合图4，如图7所示，第一导管230设于连通件200，其一端置于导入口210内，并与置于阀门300内的第三导管330连通，另一端和导气腔120连通。第二导管240设于连通件200，其一端置于导出口220内，与作用导管400连通，另一端与容器的内腔110连通。
本实施例中，导气腔120是在容器的壳体130侧壁上开设的四周封闭的槽体，或为能与第一导管230和容器的内腔110相连通的管路。一种优先选择的实施方式，其通向容器内腔的导气腔的端口121，其端面朝向壳体130的底面，使其内的气体将置于容器腔体内的粉末从腔底由下至上推动。
为便于作用导管的弯折部的开口端面朝向创伤处，便于止血剂的准确施用，本实施例的止血装置，还包括套管500，套管的一端置于导出口220内，并与第二导管240连通，套管的外壁与导出口的内壁形成非锥度配合。作用导管300另一端设于套管500内，第一夹具710与导出口220配合(如：螺纹)，以将套管500一端固定于导出口内(参见图7)。密封件711置于导出口220的开口处，以保持连接处的密封性。
为便于对作用导管施加作用力进行转动，本实施例的止血装置还于套管外设置转向件600，与套管500过盈配合。在装置整体位置不变动的情况下，使其弯折部的开口端面朝向创伤处，便于止血剂的准确施用。
如图8所示，其提供了另一种用于创伤止血装置的实施方式，其具有一个容器100，用于容纳止血剂，放置于托架800。本实施例连通件200为换向连接件，用于改变物质(如：气流和止血剂等)的运动方向，其分别与容器100和作用导管400连接。作用导管400的出射端折弯形成弯折部410，以利于止血剂作用于创伤处。
如图9和图10所示，容器100的壳体130置于托架800上。托架800包括第一导管820，其一端与阀门830连通，另一端设于架体810，与外接压力源连通。
阀门830与设于容器100的第一开口140连接。本实施例中，阀门830包括阀体831、阀杆832和复位件833。阀体831分别与第一开口140和第一导管820连接，阀杆832主体置于阀体831内，一端伸出阀体831外。以弹簧为复位件433置于阀体831内，其一端与阀杆832的一端相抵，阀杆该端与阀体锥度配合。伸出阀体外的阀杆832受外力作用(如图10所示，向左侧按压)，与阀杆相抵的复位件受力而发生位移(如图10所示，向左侧位移)，而使阀杆832与阀体831锥度配合处产生间隙(未示出)，使气流由第一导管820向第一开口140处流动，而进入容器内腔。容器中的物质(如：止血剂)受气流的带动而向第二开口150运动。
与上述情形相反的，当外力撤除后，复位件复位，推动与其相抵的阀杆移动，使得阀杆与阀体处的间隙被关闭，而使第一导管中的气体停止向容器内腔流动，容器中的物质(如：止血剂)也相应停止向第二开口的运动。
容器100还设有导气腔120，与第一开口140和容器内腔110连通。本实施例中，导气腔是在壳体侧壁上开设的四周封闭的槽体，或为能与第一开口和容器的内腔相连通的管路。一种优先选择的实施方式，其通向容器内腔的导气腔的端口121，其端面朝向壳体130的底面，使其内的气体将置于容器腔体内的粉末从腔底由下至上推动。
连通件将进入的物质的运动方向转换一个角度，而改变物质的运动方向后从导出口处排出。运动方向的改变应当理解为与导入口出的物质运动方向不同，即使与导入口处的运动方向相反(夹角180度)，物质的运动方向也实现了转换。
本实施例中，连通件200包括导入口210，与第二开口150连接。如图3所示，导入口210外形呈圆台状，同时第二开口150为喇叭口状，与导入口实现锥度配合。换向腔体230将由导入口210垂直运动的气流和止血剂的方向经换向，变换为更接近水平的运动方向，并由导出口220排出。为进一步使导入口 210与第二开口150牢固连接，在导入口210与第二开口150的连接处还设置第二夹具720，以螺纹的方式同时与导入口210与第二开口150连接。
作用导管400另一端设于套管内，第一夹具710与导出口220配合(如：螺纹)，以将套管420一端固定于导出口内。密封件711置于导出口的开口处，以保持连接处的密封性。
为便于在创伤止血中，使其弯折部的开口端面朝向创伤处，便于止血剂的准确施用。如图10所示，在套管500外还设有转向件600，并与套管500过盈配合。
将通气连接管与压力源(如：医院中央供氧系统输出端(400KPa)、医用氧气的气体钢瓶或压缩空气)连接，或者为充气容器(如：气囊，便于携带和应用)，其作为压力气源与连接于本实施例提供的各种装置，并受阀门的控制，使具有压力的气体经通气连接管连接的入口处进入止血剂容器内腔，经由另一端的端面喷出后，推动止血剂向出口运动，并经与出口连通的作用导管而将止血剂送出，即可使止血剂直接作用于创伤表面，通过调节气压即可对创伤表面施加恒定的作用力。
在医务工作中，还会涉及不同的止血部位或要求，需要对作用导管的端部形状进行调整。因此，为便于使用，还可包括角度成型模具(参见图11和图12)，包括至少1个弯折加工槽910,920,930，包括第一槽壁911、第二槽壁912和第三槽壁913，第三槽壁913和第二槽壁912形成夹角。第一槽壁911与第二槽壁912形成固定区914，以容纳并固定作用导管出射端的端部，第一槽壁911与第三槽壁913形成折弯区915，第三槽壁913确定作用导管出射端的弯折角度。
根据创伤组织(如：腔道)或手术(如：腔镜)的操作需要，通过弯折加工槽在0°～90°的范围内随时对作用导管的止血剂喷射端部的弯折角度自行进行加工和定型，如：但不仅限于15°、30°、40°、60°、75°和90°等。
将上述实施例提供的装置用于表皮组织、皮下组织、鼻窦、颅脑、胸腔及胸腔内脏器、肝脏及腹腔内脏器、肾脏及泌尿系统脏器等，即可实现快速、安全、有效的止血。例如：鼻腔喷射式止血实验数据：喷射头部距离出血点1.5-2cm， 用40KPa-80KPa气压、局部出血点处受0.3KPa-0.8KPa压力，均能在直视下看到创伤处得到有效地快速止血。
