綜合上述技術特徵，本創作之藥粉推進裝置及其藥瓶、藥瓶之瓶蓋的主要功效將可於下述實施例清楚呈現。 Based on the above technical features, the main effects of the medicinal powder propelling device and its medicine bottle and the bottle cap of the medicine bottle of this invention will be clearly presented in the following embodiments.

參閱第一圖及第二圖所示，本實施例之藥瓶1包括：一瓶體11及一瓶蓋12。該瓶體11有一瓶口111，且該瓶體11內裝填有一藥粉2。該瓶蓋12包含有一蓋體121、一給藥管122、一給氣管123及二防塵套件124：該蓋體121有一頂部1211及相對該頂部1211之一蓋部1212，該蓋體121蓋設於該瓶體11上而封閉該瓶口111；該給藥管122自該頂部1211伸入該蓋體121，該給藥管122有一進藥端1221穿透該頂部1211並連通該瓶口111，例如與該頂部1211的底面齊平；該給氣管123自該頂部1211伸入該蓋體121中，該給氣管123有一給氣端1231穿透該頂部1211並自該蓋部1212伸出並自該瓶口111伸入該瓶體11中，且該給氣端1231於該藥瓶1倒置時伸入該瓶體11中未裝填該藥粉2一未裝填空間112中；上述防塵套件124則分別套設在該給藥管122及該給氣管123位在該蓋體121之頂部1211之一端，藉以在該藥瓶1未使用時，避免該給藥管122及該給氣管123沾染灰塵髒污或病菌，也可避免該藥瓶1內的藥粉2受到汙染。 Referring to the first and second figures, the medicine bottle 1 of this embodiment includes: a bottle body 11 and a bottle cap 12. The bottle body 11 has a bottle mouth 111, and the bottle body 11 is filled with a medicine powder 2. The bottle cap 12 includes a cap body 121, a drug delivery tube 122, a trachea 123 and two dustproof kits 124: the cap body 121 has a top part 1211 and a cap part 1212 opposite to the top part 1211, and the cap body 121 covers On the bottle body 11 to close the bottle mouth 111; the drug delivery tube 122 extends from the top 1211 into the cover 121, the drug delivery tube 122 has a drug feeding end 1221 that penetrates the top 1211 and is connected to the bottle mouth 111 , For example, flush with the bottom surface of the top 1211; the air supply tube 123 extends from the top 1211 into the cover 121, and the air supply The tube 123 has an air supply end 1231 that penetrates the top part 1211 and extends from the cap 1212 and extends from the bottle mouth 111 into the bottle body 11, and the air supply end 1231 extends into the bottle body 11 when the medicine bottle 1 is inverted. The bottle body 11 is not filled with the powder 2 in an unfilled space 112; the dustproof kit 124 is respectively sleeved on the drug delivery tube 122 and the air supply tube 123 at one end of the top 1211 of the cover body 121, so that When the medicine bottle 1 is not in use, the drug delivery tube 122 and the trachea 123 are prevented from being contaminated with dust, dirt or germs, and the medicine powder 2 in the medicine bottle 1 can also be prevented from being contaminated.

參閱第三圖及第四圖所示，本實施例之藥粉推進裝置更包括有一給氣件3，該給氣件3連接該給氣管123，本實施例該給氣件3包括一打氣件31、一逆止閥32及一粉塵過濾器33，該粉塵過濾器33結合在該給氣管123上，該粉塵過濾器33中有一過濾片331，該逆止閥32結合在該粉塵過濾器33上，該打氣件31結合在該逆止閥32上，且該打氣件31於本實施例係使用針筒，該逆止閥32則包括一第一逆止部321及一第二逆止部322，該第一逆止部321連接該粉塵過濾器33，該第二逆止部322連通外界並位在該第一逆止部321與該打氣件31之間。 Referring to the third and fourth figures, the powder propelling device of this embodiment further includes an air feeding member 3 connected to the air feeding tube 123. In this embodiment, the air feeding member 3 includes an air pump 31 , A check valve 32 and a dust filter 33, the dust filter 33 is coupled to the air supply pipe 123, the dust filter 33 has a filter 331, the check valve 32 is coupled to the dust filter 33 , The pump 31 is combined with the check valve 32, and the pump 31 uses a syringe in this embodiment, the check valve 32 includes a first check portion 321 and a second check portion 322 The first check portion 321 is connected to the dust filter 33, and the second check portion 322 communicates with the outside and is located between the first check portion 321 and the air pump 31.

參閱第五圖所示，使用於內腔室給藥時，在該給藥管122上結合一內腔室插管內管4。將該內腔室插管內管4伸入人體內腔室中，並對準待給藥處，之後由該打氣件31將氣體經由該給氣管123的給氣端1231打入該藥瓶1之瓶體11的未裝填空間112，使該未裝填空間112的壓力上升，此時該瓶體11內的藥粉2會受到高壓的擠壓而自該進藥端1221經由該給藥管122而進入該內腔室插管內管4，再由該內腔室插管內管4對該待給藥處進行給藥；而該進藥端1221與該頂部1211的底面齊平可以確保該瓶體11內的藥粉2皆能夠被使用而不會殘留。 Referring to the fifth figure, when used for intra-cavity drug delivery, the drug delivery tube 122 is combined with an inner-cavity cannula inner tube 4. Extend the inner chamber cannula inner tube 4 into the human body cavity and aim at the place to be administered, and then the air pump 31 injects gas into the medicine bottle 1 through the air supply end 1231 of the trachea 123 The unfilled space 112 of the bottle body 11 increases the pressure of the unfilled space 112. At this time, the powder 2 in the bottle body 11 will be squeezed by high pressure, and the medicine powder 2 in the bottle body 11 will be squeezed from the medicine feeding end 1221 through the dosing tube 122 Into the inner chamber cannula the inner tube 4, and then the inner chamber cannula inner tube 4 is used to administer the drug to the place to be administered; and the injection end 1221 is flush with the bottom surface of the top part 1211 to ensure that the bottle The powder 2 in the body 11 can be used without leaving behind.

要進一步說明的是，由於不壓縮該藥瓶1，而使用外部的該給氣件3輸入氣體至該藥瓶1的未裝填空間112，使該藥瓶1內的藥粉2可受壓力而輸出，因此不會有如前案之藥粉卡在藥瓶，並影響藥瓶壓縮的問題；另該打氣件31使用針筒而能夠如唧筒般打氣，因此透過該粉塵過濾器33及該逆止閥32，可以避免該藥粉2因為負壓而進入該打氣件31中。 It should be further explained that since the medicine bottle 1 is not compressed, and the external gas supply member 3 is used to input gas into the unfilled space 112 of the medicine bottle 1, so that the medicine powder 2 in the medicine bottle 1 can be output under pressure. Therefore, there will be no problem that the medicine powder stuck in the medicine bottle as in the previous case and affects the compression of the medicine bottle; in addition, the inflator 31 uses a syringe to pump air like a pump, so it passes through the dust filter 33 and the check valve 32 Therefore, it is possible to prevent the medicinal powder 2 from entering the inflator 31 due to negative pressure.

綜合上述實施例之說明，當可充分瞭解本創作之操作、使用及本創作產生之功效，惟以上所述實施例僅係為本創作之較佳實施例，當不能以此限定本創作實施之範圍，即依本創作申請專利範圍及創作說明內容所作簡單的等效變化與修飾，皆屬本創作涵蓋之範圍內。 Based on the description of the above-mentioned embodiments, when we can fully understand the operation, use and effects of this creation, the above-mentioned embodiments are only the preferred embodiments of this creation, and the implementation of this creation cannot be limited by this. The scope, that is, the simple equivalent changes and modifications made according to the scope of the patent application for this creation and the content of the creation description, are all within the scope of this creation.
