Abstract

The invention relates to a semisolid and liquid preparation dosing device. The semisolid and liquid preparation dosing device comprises an outer covering protection cover, a dosing opening, a cylinder, a push-pull rod and a lock catch easy to disassemble. The dosing opening is covered with the outer covering protection cover. The dosing opening is connected to the cylinder. Scales are arranged on the surface of the cylinder. One-way linear saws are arranged inside the cylinder and on the surface of the push-pull rod, the one-way linear saw inside the cylinder is just coincident with the one-way linear saw on the surface of the push-pull rod, and the one-way linear saw inside the cylinder and the one-way linear saw on the surface of the push-pull rod can be automatically locked by pushing and pulling the push-pull rod. The lock catch easy to disassemble is arranged at the portion where the push-pull rod is connected with the cylinder, and the cylinder and the push-pull rod can be fixed through the lock catch easy to disassemble. The semisolid and liquid preparation dosing device has the advantages that the semisolid and liquid preparation dosing device is suitable for semisolid ointment preparations, aquogel preparations, paste preparations, liquid preparations and the like, and inconvenience and waste of a traditional semisolid and liquid drug dosing and storing device can be avoided.

Description

technical field [0001] The invention relates to the technical field of administration of semi-solid and liquid preparations, in particular to a novel drug storage and administration device for semi-solid and liquid preparations. Background technique [0002] Clinically applied liquid preparations include solutions, aromatic waters, syrups, spirits, tinctures, glycerin, and paints, etc. When they are used, most of them are stored and administered separately, resulting in additional waste of medical resources . Clinically applied semi-solid preparations include ointments, gels, pastes and suppositories. When ointments, gels and pastes are used clinically, most of them are packaged in tubes, but the inconvenience of extrusion in tube packages will cause the waste, and it will bring certain troubles to doctors when administering drugs. [0003] Chinese patent document CN1244132A discloses a device for topical administration of solid or semi-solid preparations, said device comp...
