Specific embodiment

The purpose of this utility model, technical solution and its effect in order to facilitate understanding, now will be in conjunction with the embodiments practical to this It is novel to be elaborated further.

As shown in Figure 1, Figure 2 and Figure 3, a kind of novel asepsis suppository drug delivery device of the utility model, including sleeve 1 and One push rod 2 is in syringe-like；First push rod 2 protrudes into one end in sleeve 1 equipped with bowl-shape holding tank 3, is inside used for It is put into suppository 12；Further include the second push rod 4 and struts head end 5；Second push rod 4 is passed through out of hollow the first push rod 2, The one end for being pierced by accommodating chamber is equipped with claw-like head 6, for being inserted into suppository 12；The outer wall of second push rod 4 is equipped with and first The raised line 7 that slot on the inner wall of the inside of push rod 2 is used cooperatively；The head end 5 that struts is at warhead shape；It includes several branch Blade 8, when the first push rod 2 pushes suppository 12, several support chips 8 are unfolded.

A kind of novel asepsis suppository drug delivery device of the utility model, when in use, medical staff is first by second Push rod 4 pushes out of first push rod 2；Until the claw-like head 6 of the second push rod 4 stretches out the first push rod 2 until its holding tank 3 It is interior；Then the suppository 12 pushed will be needed to be put into the holding tank 3, and the claw-like head 6 is inserted into the suppository 12；Then again Head end 5 will be strutted to be connected through a screw thread with sleeve 1；At this point, will strut head end 5 is directed at anus position；Appropriateness insertion；Then start Push pushes the first push rod 2 to advance, at this point, the aperture 11 that suppository 12 is pierced by the sleeve 1, which enters, struts head end 5；At this point, the support Beginning end 5 can slowly strut under the action of suppository 12, and the film 9 for filling lubricating oil can be bursting at the collision, then outflow of lubrication oil；Just It is pushed in suppository 12；The second push rod 4 is pushed again, until it reaches scheduled position；Finally, slowly extracting the second push rod 4 out ?.
