Medicament delivery and simulation system with a removable disposable container for medicament and a rotatable actuation component

Abstract

In one embodiment of the invention, a container for storing a medicament prior to use is provided. The container includes a first housing for containing a medicament, a second housing, wherein the first housing is movable relative to the second housing, and an injection member associated with a lower portion of the first housing, wherein when the first housing moves relative to the second housing in a first direction to deliver the medicament, the injection member extends from the second housing traversing a first contaminant barrier disposed at a lower portion of the second housing. The first housing moves relative to the second housing in a second direction wherein the injection member is retracted into the second housing to prevent an unintentional contact with the injection member. In a further embodiment, an actuation mechanism for actuation of an injection includes a rotatable member.

What is claimed is: 
     
         1 . A container for storing a medicament prior to use, the container comprising:
 a first housing for containing a medicament;   a second housing, wherein the first housing is movable relative to the second housing; and   an injection member associated with a lower portion of the first housing;   wherein when the first housing moves relative to the second housing in a first direction to deliver the medicament, the injection member extends from the second housing traversing a first contaminant barrier disposed at a lower portion of the second housing, and when the first housing moves relative to the second housing in a second direction the injection member is retracted into the second housing to prevent an unintentional contact with the injection member.   
     
     
         2 . The container of  claim 1 , further comprising a stopper associated with the first housing, said stopper being movable relative to the first housing, whereby the medicament is delivered through the injection member upon movement of the first housing relative to the second housing in a first direction followed by movement of the stopper relative to the first housing in a first direction. 
     
     
         3 . The container of  claim 2 , wherein the injection member traverses the first contaminant barrier and the stopper is depressed so as to deliver the medicament through the injection member. 
     
     
         4 . The container of  claim 1 , wherein the first contaminant barrier is a membrane. 
     
     
         5 . The container of  claim 1 , wherein a spring is disposed between the first and second housings such that when the first housing moves relative to the second housing in a first direction, the spring is biased, and after the medicament is delivered from the injection member the spring is released and the injection member is retracted into the second housing. 
     
     
         6 . The container of  claim 1 , further comprising a second contaminant barrier between the second housing and the first housing to prevent contaminants from entering the second housing. 
     
     
         7 . The container of  claim 2 , wherein the stopper is associated with a shaft. 
     
     
         8 . The container of  claim 2 , wherein the stopper is associated with a third contaminant barrier. 
     
     
         9 . The container of  claim 8 , wherein the third contaminant barrier prevents contaminants from entering the first housing and/or the medicament. 
     
     
         10 . The container of  claim 1 , wherein the container does not comprise an actuation mechanism. 
     
     
         11 . A medicament delivery or injection simulation system, comprising:
 a container, the container comprising a first housing and a second housing, wherein the first housing is movable relative to the second housing;   an injection member or an injection simulation member associated with a lower portion of the first housing, wherein when the first housing moves relative to the second housing in a first direction, the injection member or injection simulation member extends from the second housing traversing a first contaminant barrier disposed at a lower portion of the second housing, and the first housing moves relative to the second housing in a second direction the injection member or injection simulation member is retracted into the second housing to prevent an unintentional contact with the injection member or injection simulation member; and   an actuation mechanism associated with the container, wherein said actuation mechanism drives the movement of the first housing.   
     
     
         12 . The medicament delivery or injection simulation system of  claim 11 , wherein the actuation mechanism comprises a motor. 
     
     
         13 . The medicament delivery or injection simulation system of  claim 11 , wherein the first contaminant barrier is a membrane. 
     
     
         14 . The medicament delivery or injection simulation system of  claim 11 , wherein the container comprises a medicament. 
     
     
         15 . The medicament delivery or injection simulation system of  claim 11 , further comprising a stopper associated with the first housing, said stopper being movable relative to the first housing, whereby the medicament is delivered through the injection member upon movement of the first housing relative to the second housing in a first direction followed by movement of the stopper relative to the first housing in a first direction. 
     
     
         16 . The medicament delivery or injection simulation system of  claim 15 , wherein the actuation mechanism comprises a motor that drives the movement of the stopper. 
     
     
         17 . The medicament delivery or injection simulation system of  claim 11 , further comprising a second contaminant barrier between an upper portion of the second housing and the lower portion of the first housing to prevent contaminants from entering the second housing. 
     
     
         18 . The medicament delivery or injection simulation system of  claim 15 , wherein a third contaminant barrier is disposed between the stopper and the first housing to prevent contaminants from entering the first housing and/or the medicament. 
     
     
         19 . The medicament delivery or injection simulation system of  claim 11 , further comprising a reusable housing, said reusable housing comprising a receptacle for receiving said container. 
     
     
         20 . The medicament delivery or injection simulation system of  claim 19 , wherein said actuation mechanism is in said reusable housing. 
     
     
         21 . The medicament delivery or injection simulation system of  claim 15 , further comprising a shaft connected to said stopper. 
     
     
         22 . A container for storing a medicament prior to use, the container comprising:
 a first housing for containing a medicament;   a second housing, wherein the first housing is movable relative to the second housing;   an injection member associated with a lower portion of the first housing; and   a plunger associated with the first housing, said plunger being movable relative to the first housing;   wherein when the first housing moves relative to the second housing in a first direction to deliver the medicament, the injection member extends from the second housing traversing a first contaminant barrier disposed at a lower portion of the second housing, and wherein when the plunger moves relative to the first housing in a first direction, medicament is delivered through the injection member, and when the first housing moves relative to the second housing in a second direction the injection member is retracted into the second housing to prevent an unintentional contact with the injection member.
