    • The application refers to hypodermic needles (101) for the parenteral administration of liquids. The needles incorporate at their sharp-end an obstruction (102) of rapidly water-soluble material that dissolves within living tissues once the needle is injected. These needles ensure that the end user can only operate the syringe, or injection device, once the needle has been injected. The use of these hypodermic needles avoids the possibility of the user expelling any amount of liquid prior injection, ensuring the administration of the complete dose. These hypodermic needles are of special interest in preloaded injection devices and in the administration of small volumes of liquid were ejection of part of the dose by the user may result in the administration of only a fraction of the intended dose.
    • 该应用是指用于肠胃外给药液体的皮下注射针(101)。 这些针在其尖端处包含快速水溶性材料的阻塞物(102),一旦针头被注射就溶解在活组织内。 这些针确保一旦注射针头,最终用户只能操作注射器或注射装置。 使用这些皮下注射针避免了用户在注射前排出任何量的液体的可能性,从而确保了完整剂量的给药。 这些皮下注射针对预加载的注射装置是特别有用的,并且在施用小体积的液体时,使用者的部分剂量的喷射可能仅导致预期剂量的一部分。

    • The present invention is a pharmaceutical composition and method for controlling the release of a drug or vaccine to a patient where a slow, controlled release of drug or antigen occurs over a considerable period of time after injection. The drug or vaccine is contained in sugar glass microspheres and then placed in an anhydrous liquid, preferably perfluorocarbon, so that the vaccine is protected against dissolution while remaining surrounded by anhydrous liquid. This simple non-toxic system, deliverable by current syringe or present or future needle-free systems, is inexpensive and reliable and aids in parenteral drug delivery or mass immunization campaigns by reducing the need for repeated injections.
    • 本发明是用于控制药物或疫苗释放到患者的药物组合物和方法,其中在注射后相当长的一段时间内发生药物或抗原的缓慢的受控释放。 药物或疫苗包含在糖玻璃微球中,然后置于无水液体中,优选全氟化碳,以使疫苗得到保护以防止溶解,同时保持被无水液体包围。 这种简单的无毒系统,可由当前的注射器或现在或将来的无针系统交付,价格便宜且可靠,通过减少重复注射的需要,有助于肠胃外药物输送或大规模免疫运动。
