Description

加压气体注射装置及方法 技术领域
本发明涉及一种加压气体注射装置，尤其涉及一种无针注射加压气体至皮肤内的加压气体注射装置。
背景技术
由于使用针头注射药物容易使患者产生不适的刺痛感，因此一种“无针注射”技术乃因此而生，所谓“无针注射”就是在进行药物注射时不使用针头，而是将液体药物以极细的直径高速直线喷出，以其自身的动能使药物穿过皮肤而进入到生物(例如人体或动物)的体内。由于流体本身的特性，当液体药物进入生物内部组织后，可沿着组织纤维的间隙扩散分布，因此进入过程对组织损伤极小，同时药物可有效地分布扩散而有利于吸收。
然而，目前所注射的药物大多是以液体为主，若欲使用气体作为注射药物时往往会有有效进入皮肤分子不足的问题，进而影响到药物注入注射目标物的深度及效果，也就是说气体不易注入到人体皮肤下方的肌膜、肌肉或关节，故难以提升人体对于药物的吸收效果。此外，当以气体作为注射药物时，无针注射装置也需要对注射气体的体积或注射时间进行良好的控制，以兼顾高效率以及安全性的要求。

具体实施方式
现配合附图说明本发明的实施例。
首先请参照图1A，本发明一实施例的加压气体注射装置1包括一外壳S以及一驱动机构T(例如一可活动的板机)，其中在外壳S内设有一排气单元10、一储气单元20以及至少两个密封环O1、O2。前述排气单元10具有一排气口11以及一穿孔V，排气口11是用以将一加压气体排出加压气体注射装置1。储气单元20活动地设置于排气单元10内，包括一中空的本体22及一杆件23，其中杆件23以可调整位置的方式插设于本体22内， 且本体22与杆件23之间形成有一腔室C，用以储存加压气体，此外一气体通道21形成于本体22内，并与前述腔室C相连通。前述两个密封环O1、O2设置于排气单元10的内壁并抵接本体22，用以防止气体泄漏。
于本实施例中，被注入到腔室C内的加压气体的压力可大于或等于5兆帕。应了解的是，在本实施例中可通过杆件23和本体22内侧壁上相对应的螺纹结构(未图标)，使得杆件23能通过旋转的方式而在本体22内部前进或后退，进而改变前述腔室C的体积大小，以达到调整并提供不同定量容积的注射气体的目的；其中，在杆件23和本体22内侧壁之间设有密封环O23。
请继续参照图1A，前述驱动机构T枢接外壳S以及储气单元20，且其可受外力按压而相对于外壳S旋转，借以驱使储气单元20于前述排气单元10内移动。在未按压驱动机构T之前，储气单元20相对排气单元10位于一第一位置(图1A)，此时由于气体通道21的开口位于两个密封环O1、O2之间，并直接和穿孔V相连通，因此一加压气体可依序经由外壳S上的气体注入口G、与气体注入口G相连接的穿孔V以及气体通道21而进入储气单元20的腔室C内(如图1A中箭头方向所示)，进而使前述加压气体注射装置1处于一充气状态。
接着请一并参照图1B和1C，其为当储气单元20相对排气单元10由前述第一位置移动到第二位置时的剖面示意图。如图1B和图1C中箭头方向所示，当用户按压驱动机构T时，储气单元20可相对于排气单元10由前述第一位置移动到第二位置，此时由于气体通道21的开口移动至排气口11与两个密封环O1、O2之间，因此位于腔室C内的加压气体便可依序经由气体通道21以及排气口11而排出加压气体注射装置1(如图1B中箭头方向所示)，进而使前述加压气体注射装置1处于一排气状态。
接着，当用户释放前述驱动机构T时，设置于储气单元20与排气单元10的偏压组件30(例如压缩弹簧)即可提供一弹力使储气单元20相对于排气单元10由前述第二位置(图1B)回复到如图1A所示的第一位置。通过前述机构设计，可将压力大于或等于5兆帕的加压气体直接穿过皮肤而到达真皮层或皮下的更深处，进而能达到良好的治疗效果。
接着请参照图2A，本发明另一实施例的加压气体注射装置1与前述图1A和图1B所示的加压气体注射装置1主要不同之处在于：本实施例中还包括一组并排且相互固定的储气单元(包括第一储气单元20A以及第二储气单元20B)，此外在排气单元10和两个储气单元20A、20B的外侧更设有一壳体H。如图2A所示，前述排气单元10具有一排气口 11，其中位于上侧的第一储气单元20A形成有一第一注入气体通道21I及一第一排出气体通道21O，位于下侧的第二储气单元20B则形成有一第二注入气体通道21I’及一第二排出气体通道21O’，两个密封环O1、O2设置于排气单元10的外侧表面，并抵接第一储气单元20A及第二储气单元20B的内侧壁，以防止气体从排气单元10和储气单元20A、20B之间的缝隙泄漏。
请继续参照图2A，前述加压气体注射装置1更设有两个第一注气密封环O3、O4、两个第二注气密封环O5、O6以及一偏压组件30，且壳体H具有一第一气体注入口H1及一第二气体注入口H2，用以将气体分别注入第一储气单元20A及第二储气单元20B的腔室C1、C2内(如图2A中箭头方向所示)。应了解的是，前述两个第一注气密封环O3、O4设置于壳体H的内壁，并对应第一气体注入口H1以防止气体泄漏，前述两个第二注气密封环O5、O6则是设置于壳体H的内壁，并对应第二气体注入口H2以防止气体泄漏；此外，前述偏压组件30(例如压缩弹簧)则是设置于排气单元10与前述两个储气单元20A、20B之间。
需特别说明的是，当偏压组件30于一初始状态时(如图2A所示)，第一储气单元20A及第二储气单元20B相对于排气单元10位于一第一位置，且第一注入气体通道21I及第二注入气体通道21I’会分别位于两个第一注气密封环O3、O4之间以及两个第二注气密封环O5、O6之间。由此，如图2A中箭头方向所示，一第一加压气体可依序经由第一气体注入口H1以及第一注入气体通道21I而进入到第一储气单元20A的腔室C1内，且一第二加压气体可依序经由第二气体注入口H2以及第二注入气体通道21I’而进入到第二储气单元20B的腔室C2内。
由于第一排出气体通道21O及第二排出气体通道21O’分别位于两个密封环O1、O2之间，故此时气体因受到阻挡而无法经由排气口11排出加压气体注射装置1，使得加压气体注射装置1可处于一充气状态，其中经由第一、第二气体注入口H1、H2进入到腔室C1、C2内的第一、第二加压气体不会相互混合。于本实施例中，第一加压气体及第二加压气体的压力可大于或等于5兆帕，且第一、第二加压气体的气压值可彼此相异。
接着请参照图2B，其为当第一储气单元20A及第二储气单元20B相对于排气单元10由前述第一位置移动到第二位置时的剖面示意图。如图2B所示，当欲排出加压气体以进行注射时，可通过板机或其他驱动机构施加一外力，借以将第一储气单元20A及第二储气单元20B相对于排气单元10由前述第一位置朝排气口11的方向移动到第二位置，并使偏 压组件30会受到进一步的压缩。在此状态下，第一排出气体通道21O及第二排出气体通道21O’会移动到两个密封环O1、O2与排气口11之间，使得位于第一储气单元20A内的第一加压气体可依序经由第一排出气体通道21O以及排气口11而排出加压气体注射装置；同理，也可使得位于第二储气单元20B内的第二加压气体能依序经由第二排出气体通道21O’以及排气口11而排出加压气体注射装置1，进而使加压气体注射装置1处于一排气状态。
通过前述机构设计，可将压力大于或等于5兆帕的加压气体直接穿过皮肤而到达真皮层或皮下的更深处，进而达到良好的治疗效果。另一方面，由于本实施例中的第一储气单元20A及第二储气单元20B可利用不同的腔室C1、C2以分别储存第一加压气体及第二加压气体，因此可混合不同的气体以作为注射药物。
再请参照图3A，本发明另一实施例的加压气体注射装置1主要包括一排气单元10、一储气单元20、两个密封环O1、O2、一偏压组件30以及一刺针N。如图3A所示，排气单元10具有一排气口11以及一气体暂存槽12，此气体暂存槽12是可拆卸并置换，以改变其内部体积大小，以达到调整并提供不同定量容积的注射气体的目的，储气单元20活动地连接排气单元10，且包括一滑动件24以及一加压气瓶25。应了解的是，前述加压气瓶25是以可拆卸的方式连接滑动件24，且滑动件24内部形成有一气体通道21，两个密封环O1、O2则设置于排气单元10的内壁，并抵接储气单元20的外侧表面以防止气体泄漏，刺针N则是设置于滑动件24的一侧，用以刺穿加压气瓶25上的一金属或塑料材质所制成的封口件(未图示)，使加压气体可从加压气瓶25进入到气体通道21中。
请继续参照图3A，当储气单元20相对于排气单元10位于一第一位置时，由于气体通道21的开口位于两个密封环O1、O2之间，因此加压气瓶25内的一加压气体会经过气体通道21而进入到气体暂存槽12内，使得前述加压气体注射装置1处于一充气状态；于本实施例中，前述加压气体的压力可大于或等于5兆帕。
接着请参照图3B，其为图3A中的储气单元20相对于排气单元10由第一位置移动到第二位置时的剖面示意图。如图3B所示，当欲排出加压气体以进行注射时，可施加一外力予加压气瓶25，以推动储气单元20由前述第一位置相对于排气单元10移动到第二位置，此时由于气体通道21靠近气体暂存槽12的一开口位置已不在两个密封环O1、O2之间，而是位于两个密封环O1、O2与气体暂存槽12之间，因此气体暂存槽12内的加压气体便可从经由排气口11排出加压气体注射装置1(如图3B中箭头方向所示)，以使前述加 压气体注射装置1处于一排气状态。
通过前述机构设计，可将压力大于或等于5兆帕的加压气体直接穿过皮肤而到达真皮层或皮下的更深处，进而达到良好的治疗效果。另一方面，通过设置前述可拆卸的加压气瓶25，不仅可便于携带，且患者能于家中自行更换及注射加压气体，进而能提高治疗的便利性。
此外，如图3C所示，于另一实施例中也可不使用可拆卸的加压气瓶25，而是使前述滑动件24内部的气体通道21通过管路U1、U2而连接到一外部的大型气体源U，借以持续不间断地提供加压气体到加压气体注射装置1内，其中滑动件24和管路U1可组成一储气单元20。
再请参照图4A，本发明另一实施例的加压气体注射装置1包括一排气单元10、一主储气单元20以及一单向阀40。前述排气单元10具有一排气口11，主储气单元20则是通过单向阀40连接排气单元10，其中主储气单元20包括一第一储气组件26、一第一滑动组件27以及两个第一密封环O1、O2。前述第一储气组件26形成有一第一气体通道21以及一第一腔室C，其中第一腔室C可用以容纳一加压气体，第一滑动组件27则活动地套设于第一储气组件26的外侧；此外，两个第一密封环O1、O2设置于第一滑动组件27的内壁，并抵接第一储气组件26的外侧表面以防止气体泄漏。
请继续参照图4A，当第一滑动组件27相对于第一储气组件23位于一第一关闭位置时，由于第一气体通道21靠近排气单元10的一部分会位于两个第一密封环O1、O2与排气单元10之间，因此第一气体通道21并未导通，进而可防止第一腔室C内的加压气体经由第一气体通道21和单向阀40而进入到排气单元10，且能使前述加压气体注射装置1处于一充气状态；于本实施例中，前述加压气体的压力可大于或等于5兆帕。需特别说明的是，前述排气单元10另可与多个储气单元串接，以达到调整并提供不同定量容积的注射气体的目的，其详细结构则可参考以下实施例的说明。
接着请参照图4B，其为当图4A中的第一滑动组件27相对于第一储气组件26由第一关闭位置移动到第一开启位置时的剖面示意图。如图4B所示，当欲排出加压气体以进行注射时，可将第一滑动组件27相对于第一储气组件26移动到一第一开启位置，并使第一气体通道21位于两个第一密封环O1、O2之间，此时第一腔室C内的加压气体便可由第一气体通道21和单向阀40而进入排气单元10，并从排气口11排出加压气体注射装置1，此时加压气体注射装置1即可处于一排气状态。通过前述机构设计，同样可将压力大于或 等于5兆帕的加压气体直接穿过皮肤而到达真皮层或皮下的更深处，进而达到良好的治疗效果。
接着请参照图4C，本发明另一实施例的加压气体注射装置1除了前述排气单元10、主储气单元20以及单向阀40外，还包括一辅助储气单元20’以及另一单向阀40，其中辅助储气单元20’可通过前述单向阀40连接主储气单元20。如图4C所示，前述辅助储气单元20’包括一第二储气组件26’、一第二滑动组件27’以及两个第二密封环O1’、O2’，其中第二储气组件26’形成有一第二气体通道21’以及一第二腔室C’，前述第二腔室C’可用以容纳加压气体。在本实施例中，第二滑动组件27’活动地套设于第二储气组件26’的外侧，两个第二密封环O1’、O2’则设置于第二滑动组件27’的内壁，并抵接第二储气组件26’的外侧表面以防止气体泄漏。
请继续参照图4C，当第二滑动组件27’相对于第二储气组件23’位于一第二关闭位置时，由于第二气体通道21’靠近主储气单元20的一部分会位于两个第二密封环O1’、O2’与主储气单元20之间，因此第二气体通道21’并未导通，故可阻止第二腔室C’内的加压气体经由第二气体通道21’和单向阀40而进入到主储气单元20。
接着请参照图4D，其为当图4C中的第二滑动组件27’由第二关闭位置相对于第二储气组件26’移动到第二开启位置时的剖面示意图。如图4D所示，当第二滑动组件27’相对第二储气组件26’移动到第二开启位置时，由于第二气体通道21’会位于两个第二密封环O1’、O2’之间，因此位于第二腔室C’内的加压气体便可经由第二气体通道21’以及单向阀40而进入到主储气单元20，以使前述加压气体注射装置1处于一充气状态；同理，当欲排出加压气体以进行注射时，可将第一滑动组件27相对于第一储气组件26移动到前述第一开启位置(如图4B所示)，以使第一腔室C内的加压气体由第一气体通道21和单向阀40而进入到排气单元10，进而能从排气口11排出加压气体注射装置1；于本实施例中，前述加压气体的压力可大于或等于5兆帕。
再请参照图4E，此实施例与图4D的实施例的主要差别在于：加压气体注射装置1还包括两个辅助储气单元20’，并通过单向阀40而彼此连接。如图4E所示，当两个辅助储气单元20’的第二滑动组件27’相对该第二储气组件26’皆位于第二开启位置时，加压气体注射装置1会处于一充气状态，且图4E中的加压气体注射装置1内所能储存的所有加压气体体积总合可较图4D中的加压气体注射装置1内所储存的加压气体体积更大。换言之，本实施例通过增加或调整辅助储气单元20’的数量，并切换第二滑动组件27’ 于关闭或开启位置之间，如此一来便可选择性地提供不同体积的加压气体以作为注射之用。
接着请参照图5A，本发明另一实施例的加压气体注射装置1包括一排气单元10、一储气单元20、一偏压组件30、一第一密封环O1、一第二密封环O2、两个第三密封环O3以及两个第四密封环O4。排气单元10具有一排气口11以及一凸出部13，储气单元20则包括一间隙调节构件28以及一中空的套管29。如图5A所示，前述套管29设置于排气单元10内并可相对于排气单元10滑动，其中凸出部13延伸进入套管29内，且套管29具有对应于排气口11的一穿孔V。
需特别说明的是，前述间隙调节构件28活动地设置于套管29中且形成有一气体通道21，偏压组件30则设置于排气单元10与套管29之间，其中第一密封环O1套设于凸出部13上并抵接套管29，第二密封环O2则设置于间隙调节构件28上并抵接套管29。此外，气体通道21的一出口E朝向套管29且位于第一密封环O1和第二密封环O2之间。两个第三密封环O3则设置于套管29上并抵接排气单元10，且位于偏压组件30以及穿孔V之间。另一方面，两个第四密封环O4设置于排气单元10上并抵接套管29的外侧表面，其中排气口11位于两个第三密封环O3与两个第四密封环O4之间。
请继续参照图5A，当偏压组件30受一外力作用(例如可以手按压套管29底侧的推杆291)而处于一压缩状态时，套管29相对于排气单元10位于一第一位置，此时第一密封环O1会位于穿孔V以及出口E之间，且穿孔V会位于第一密封环O1与两个第三密封环O3之间，由此可阻止气体通道21与穿孔V导通，以避免气体通道21内的加压气体经由穿孔V泄出，并可使前述加压气体注射装置1处于一充气状态；于本实施例中，前述加压气体的压力可大于或等于5兆帕。
接着请参照图5B，其为图5A中的套管29由第一位置相对于排气单元10移动到第二位置时的剖面示意图。如图5B所示，当施加于套管29底侧推杆291的外力被释放后，偏压组件30(例如压缩弹簧)可通过其自身的弹力而回复到一展开状态，且该弹力可驱使套管29相对于排气单元10由前述第一位置移动到第二位置；需特别说明的是，此时穿孔V的位置是介于第一密封环O1和第二密封环O2之间，且穿孔V的位置也同时介于两个第三密封环O3和两个第四密封环O4之间，故由入口I注入气体通道21内的加压气体便可穿过间隙调节构件28以及出口E而到达穿孔V，接着更可依序经由穿孔V以及排气口11而排出加压气体注射装置1，以使前述加压气体注射装置1处于一排气状态。通过前述机 构设计，可将压力大于或等于5兆帕的加压气体直接穿过皮肤而到达真皮层或皮下的更深处，进而达到良好的治疗效果。
再请参照图5C，其为当图5A中的套管29相对于排气单元10进一步移动到第三位置时的剖面示意图。如图5C所示，当偏压组件30通过弹力而进一步驱使套管29相对于排气单元10由前述第二位置滑动到第三位置时，第三密封环O3/第四密封环O4的位置会介于穿孔V以及排气口11之间，故可防止穿孔V内的加压气体流向排气口11。由图5A、图5B以及图5C中可以看出，前述第二位置(图5B)是位于第一位置(图5A)与第三位置(图5C)之间，其中当套管29滑动到第三位置时，加压气体注射装置1即结束排气状态，而直到再度将推杆291推回并压缩偏压组件30时，才会使套管29相对于排气单元10回到如图5A所示的状态，以利于再次进行充气。于本实施例中，因为可通过偏压组件配合不同的密封环已进行多阶段的流路控制，所以可达到高压以及定量注射的效果，进而能提升使用上的弹性与便利性。
接着请参照图6A，其为当储气单元20的套管29相对排气单元10位于第一位置，且间隙调节构件28通过螺纹结构(未图标)旋转进入排气单元10内部，并与凸出部13之间具有最小间隙时的剖面示意图。如图6A所示，当偏压组件30处于压缩状态时，套管29会相对排气单元10位于第一位置时，此时第一密封环O1会位于穿孔V以及气体通道21的出口E之间，由此可阻止加压气体从气体通道21进入穿孔V。
再请参照图6B，其为图6A中的套管29相对排气单元10由前述第一位置移动到第二位置时的剖面示意图。如图6B所示，当偏压组件30处于展开状态并通过弹力驱使套管29相对排气单元10移动到第二位置时，由于穿孔V会位于第一密封环O1与第二密封环O2之间，且穿孔V也会位于两个第三密封环O3与两个第四密封环O4之间，因此加压气体便可从气体通道21的入口I注入间隙调节构件28，并依序经由穿孔V以及排气口11而排出加压气体注射装置1，以使前述加压气体注射装置1处于一排气状态。
接着请参照图6C，其为图6A中的套管29继续通过偏压组件30弹开而相对排气单元10移动到第四位置时的剖面示意图。如图6C所示，因为间隙调节构件28与凸出部13之间已调整至最小间隙，所以第一密封环O1与第二密封环O2之间的距离也变短了，故在偏压组件30进一步驱使套管29相对于排气单元10由第二位置滑动到第四位置的过程中，穿孔V仅会短暂地位于第二密封环O2以及第四密封环O4之间，如此可缩短穿孔V与气体通道21相互导通的时间，以防止气体通道21内的加压气体过量地经由穿孔V而流出排 气口11，意即此时加压气体注射装置1是处于一结束排气状态。如前所述，本实施例可通过调整间隙调节构件28与凸出部13之间的间隙而选择性地设定加压气体排出的时间，如此一来便能针对气体的注射时间与排出量进行良好的控制。
再请参照图6D，其为图6A的套管29相对排气单元10移动到如图5C所示的第三位置时的剖面示意图。由图6D中可以看出，当偏压组件30进一步驱使套管29相对于排气单元10由前述第二位置滑动到第三位置时，第四密封环O4会位于穿孔V以及排气口11之间，由此可防止穿孔V内的加压气体流向排气口11，此时前述加压气体注射装置1仍然处于一结束排气状态，需直到再度压缩偏压组件30并使套管29相对于排气单元10回到前述第一位置后才能再次进行充气。
接着请参照图7的实施例，其与图1C的实施例不同之处在于：外壳S并未设有气体注入口G，其中加压气体可以通过将小型气瓶(例如图7C中所示的子弹形气瓶41)安装于外壳S内，以便于随身携带使用。
图8A-8F为不同实施例的喷嘴P的示意图，其中图8C-8D为剖面示意图。如图8A-8F所示的各种不同形式的喷嘴P皆可应用于前述任何一种加压气体注射装置1，其中喷嘴P的一侧可通过单向阀连接前述排气单元10的排气口11，其另一侧则用以接触患者的皮肤，进而能将加压气体从排气口11注射到患者体内。如图8A所示，本实施例的喷嘴P具有多个可伸缩的气管，以喷嘴P能充分地贴附于患部的皮肤表面以达到有效的接触。再如第8B-8C图所示，喷嘴P内侧可形成有漏斗状结构，用以平均且大面积地将加压气体注射至患部，其中在漏斗状结构内可形成有单一气管(图8B)或多个气管(图8C)。另外，如图8D所示，喷嘴P亦可具有圆筒状结构，以精准地将加压气体注射至患部。最后，如图8E-8F所示，喷嘴P更可包含长条状的可挠性膜或是圆形的贴片，用以覆盖住患部，进而能避免加压气体外泄。应了解的是，当气体通过如图8A-8F所示之前述喷嘴P时，可在与皮肤接触处产生震动。
在本发明上述各实施例的加压气体注射装置1中，储气单元20可相对排气单元10移动，并能使加压气体穿过皮肤而到达皮下组织，进而能达到良好的治疗效果。另一方面，亦可适度增减辅助储气单元20’的数量并控制其于关闭或开启位置，借以选择性地提供不同体积的加压气体，从而能针对注射气体的进行定量的体积控制。再者，透握调整间隙调节构件28与凸出部13之间的间隙，可选择性地设定加压气体于一特定期间内排出，进而能针对气体的注射时间与排出量进行良好的控制。另一方面，本发明也可以采取一次性 使用的子弹形气瓶作为默认的注射容量，并通过更换不同容积的子弹形气瓶以调整欲注射的气体容积，进而能大幅提升使用上的弹性与便利性。
综上所述，本发明提供一种可调式定量注射高压气体的装置及方法，此气体可来自一或多个气体来源，且可包含5兆帕以上的氢、氧、氮、二氧化碳、臭氧、笑气(nitrous oxide)中至少一种。前述气体可直接接通机构里的气瓶，或是外接气源，并经过各气体对应的阀门，气体可充气到预设或可调节容积的储气室。或者，此阀门为可调控开阀时间的阀门而不需储气室。气体喷出后经过依注射深度及范围而选择的喷头，其中喷头与机构本体间设有一单向阀以避免回流与污染。操作人员可以适当力量压在需作用的人体部位，喷气注射后，由机构内的弹性装置，复位到原始状态，可用于下次注射。
虽然本发明已以具体的较佳实施例公开如上，然其并非用以限定本发明，任何熟习此项技术者，在不脱离本发明的精神和范围内，仍可作些许的更动与润饰，因此本发明的保护范围当视随附的权利要求所界定者为准。
