The present invention relates generally to a kind of delivery device and a kind of housing for this device for being used to selecting and distributing the medicament of multiple user's variable doses.Housing insert (150) that housing for delivery device includes shell body (10), is constrained in steering shell body (10) but can be directed to be axially moved relative to shell body (10), can be attached to by least one groove (21) and at least one projection (15) shell body (10) distal end cartridge-holder (20).Cartridge-holder (20) is included towards the inclined-plane (22) of nearside, and housing insert (150) includes the corresponding inclined-plane (152) towards distal side.Groove (21) includes first slope part (24) and the second ramp portion (26), the heeling condition of first slope part (24) is, so that cartridge-holder (20) when rotary attachment is moved relative to shell body (10) proximal motion, the heeling condition of second ramp portion (26) is so that cartridge-holder (20) is when rotary attachment is moved relative to shell body (10) distal motion.At least when in the second ramp portion (26) that raised (15) are located at groove (21), engage towards the inclined-plane (22) of nearside and towards the inclined-plane (152) in distal side and tilt and cause housing insert (150) in cartridge-holder (20) attachment motion relative to shell body (10) and cartridge-holder (20) proximal motion.Mevcut buluş genel olarak kullanıcıya göre değişen bir dizi ilaç maddesi dozunu seçmeye ve dağıtmaya yönelik bir ilaç dağıtım cihazı ve bu tür bir cihaza yönelik bir mahfaza ile ilgilidir. Bir ilaç dağıtım cihazına yönelik mahfaza bir dış mahfaza (10), dış mahfazaya (10) göre eksenel olarak hareket ettirilebilir olarak yönlendirilen ve dış mahfazaya (10) döner şekilde sıkıştırılan bir mahfaza ek parçası (150) ve en az bir çıkıntı (15) ile en az bir yiv (21) tarafından dış mahfazanın (10) distal ucuna bağlanabilen bir kartuş tutucu (20) içerir. Kartuş tutucu (20
