The flexible pouch which contains the liquid medicine (10) the enclosure in order to insert (11) the housing which it possesses is included, the discharge section, connected possibility, the self-sustaining type portable device in order to prescribe the liquid medicine is disclosed in the pipe in order to deliver the said liquid medicine to reshipiento. The compressed system is arranged in order to offer uniformity and control possible gas pressure to the housing, can obtain control possible pressure, for control possible delivery of the liquid medicine with that. The said compressed system includes below: Pressure source in order to send the positive pressure gas (3) In order to offer the positive pressure reservoir, it was arranged, the said source and the said enclosure (11) the pressure accumulation tank which is connected Way the gas can flow to only the direction of the said pressure accumulation tank from the said pressure source, pressure source and the unidirectional valve which is arranged between the pressure accumulation tanks And the said pressure accumulation tank and mechanical pressure adjuster which is arranged between the above-mentioned housing. With this, and well is controlled the discharge pressure and which it is possible in quite stability for the discharge flow to obtain.< Selective figure >Figure 3薬液を含有する可撓性パウチ(10)を入れるためのエンクロージャ(11)を有するハウジングを含み、その排出部が、該薬液をレシピエントに送達するための導管に接続可能な、薬液を投与するための自給型携帯装置が開示される。一定かつ制御可能なガス圧力をハウジングに供するために加圧システムが配置され、それによって制御可能な圧力が、薬液の制御可能な送達のために得られる。該加圧システムは、以下を含む:陽圧ガスを送るための圧力源(3);陽圧リザーバを供するように配置された、該源及び該エンクロージャ(11)に接続された圧力蓄積タンク;該圧力源から該圧力蓄積タンクの方向にのみガスが流れ得るように、圧力源及び圧力蓄積タンクの間に配置された一方向弁;及び該圧力蓄積タンク及び上記ハウジングの間に配置された機械的圧力調節器。これによって、極めて安定でかつよく制御された排出圧力及び排出流れが得ることができる。【選択図】図3
