Abstract

The invention discloses an external-use unguent quantitative extruding device and relates to the technical field of medical instruments. The technical effect of avoiding unguent waste is achieved. The device comprises a pipe cover, a push rod and an unguent storing chamber which is fixed to the pipe cover; an unguent quantitative outlet is formed in the left end of the unguent storing chamber; anunguent extruding inlet of the lower left portion of the unguent storing chamber is in butt joint with an outlet of a one-way valve of the upper portion of the pipe cover; a piston which can slide leftwards and rightwards, a quantitative adjusting block and a spring which is used for driving the quantitative adjusting block to move leftwards are disposed in the unguent storing chamber; a rod bodyof the push rod penetrates through a passing hole in the quantitative adjusting block; the left end of the push rod is fixedly connected with the piston; the right end of the push rod extends to theexterior of the unguent storing chamber; an adjusting clamping pin which can move up and down is disposed on the unguent storing chamber; a plurality of adjusting clamping grooves which are distributed at intervals in sequence from left to right are formed in the quantitative adjusting block; and the adjusting clamping ping is inserted into any one of the adjusting clamping grooves so that the quantitative adjusting block and the adjusting clamping pin can be mutually fixed. By means of the device provided by the invention, unguent can be quantitatively extruded according to the using demands.

Description

technical field [0001] The invention relates to medical device technology, in particular to the technology of a quantitative extruding device for external ointment. Background technique [0002] The ointment for external use is packed in a hose, and the ointment is directly extruded by squeezing the hose when in use. This direct extrusion method cannot control the amount of ointment extruded, and it is easy to squeeze out an excessive amount of ointment, resulting in waste of ointment . Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a quantitative extruding device for external ointment that can quantitatively extrude ointment and avoid waste of ointment. [0004] In order to solve the above technical problems, the present invention provides a quantitative extruding device for external ointment, which is characterized in that it includes a medicine storage...
