Further, the cylindrantherae outer wall is arranged with annular flange close to piston cylinder portion.
Compared with prior art, the utility model structure is simple, easy to operate, and dose is controllable, using screw thread promote to
Medicine more safety and comfort.
Detailed description of the invention
Fig. 1 is the organigram of the utility model；
In figure: 1- nut cap, 2- cylindrantherae, 3- piston cylinder, 4- oval plate, 5- square hole, 6- cross-bar, 7- roundel, 8- are convex
Head, 9- square head.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of rectum or vaginal administration device, including nut cap 1, cylinder and piston rod, the cylinder is by inner cavity
The cylindrantherae 2 and 3 integrally connected of piston cylinder of intercommunication form, and 2 front end aperture of cylindrantherae and are detachably encapsulated by nut cap 1, filling in cylindrantherae 2
There is drug, piston rod is set in piston cylinder 3, and piston rod front end is at least partially disposed in cylindrantherae, piston cylinder open rearward end and inner wall
It is at least partly equipped with internal screw thread close to opening, piston rod rear end is equipped with external screw thread, is threadedly coupled with piston tube rear end internal screw thread,
Piston rod rear end end is equipped with multi-party hole, and the nut cap front end is multi-party head, and size matches with multi-party hole, the nut cap outer diameter
No more than piston cylinder internal diameter.
Further, the piston rod is separately connected roundel 7 by 6 both ends of cross-bar and cylindrical body forms, outside roundel 7
Diameter is equal with cylindrantherae internal diameter, and the external screw thread is arranged on cylindrical body periphery, and cylindrical body outer diameter is equal with 3 internal diameter of piston cylinder, knot
Structure is simple, promotes reliable.
Further, 2 outer wall of cylindrantherae is equipped with insertion depth graduation mark, and the insertion of delivery device is observed convenient for medical staff
Depth, so that dose correctly gets to the medication position of patient.
Further, the drug is gelling agent or ointment or cream or granule.
Further, the multi-party hole is square hole 5, and multi-party head is square head 9.
Further, the piston cylinder open rearward end is equipped with oval plate 4, is conducive to rectum or vaginal administration device is upright.
Further, the cylindrantherae outer wall is arranged with annular flange close to piston cylinder portion, for nut cap 1 to be clamped in cylindrantherae
2 outer walls, it is convenient for disassembly and assembly, the plush copper 8 for blocking cylindrantherae front opening is equipped in the nut cap 1, sealing effect is good, avoids dose
