Abstract

The utility model discloses a gynecological drug propelling gun, which comprises a handle and a gun barrel. An automatic resetting driving lever is embedded into the handle, and rotates to enable a motor coaxially embedded into the rear end of the gun barrel to be communicated with an external or internal power supply. An output shaft of the motor is coaxially connected with an input shaft of a reduction gearbox. An output shaft of the reduction gearbox drives a screw rod. The screw rod is coaxially embedded into an ejector rod for propelling a piston in a drug tube in the gun barrel. An opening for mounting the drug tube is formed at the front end of the gun barrel. A bayonet for clamping a groove on the outer edge of the drug tube is formed on the front end part of the gun barrel. The gynecological drug propelling gun is simple in structure; and the drug tube is clamped at the front end of the gun barrel, the motor rotates after the driving lever is moved, and drives the ejector rod after being sped down, the ejector rod drives the piston in the drug tube, and the piston finishes the propelling of drug. The whole process is kept in a constant speed state and is high in speed, and the discomfort of a patient is avoided.

Description

Gynecologic medicine pushes rifle

Technical field

This utility model belongs to gynecological administration device field, and especially a kind of gynecologic medicine pushes rifle.

Background technology

Gynaecopathia is perplexing a large amount of female friends, and the not only normal life of influence also can threaten to follow-on breeding; The therapeutic effect of oral medicine is general; And the cause of disease of gynaecopathia is more, need take multiple medicine, can cause the burden of other organ of human body.At present, manufacturer is filled to medicine in the pencil, and pencil carries piston; And the doctor is when using; Adopt push rod to promote the piston in the pencil, make medicine entering women's genitals, to reach the purpose of direct administration; But this method can't be at the uniform velocity the propelling movement medicine, cause the discomfort of sufferer sometimes.

The utility model content

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of gynecologic medicine simple in structure, economy and durability to push rifle.

The technical scheme that this utility model is taked is:

A kind of gynecologic medicine pushes rifle; It is characterized in that: comprise handle and gun barrel; Setting-in one automatically reset driving lever on handle makes the motor of the coaxial setting-in of gun tube rear end be communicated with external or built-in power, the power shaft of the coaxial connection reduction box of motor output shaft after this driving lever rotation; The output shaft of this reduction box drives a leading screw; This leading screw is coaxial be inlaid in adorned in the gun barrel be used to push in the push rod of pencil inner carrier, be shaped on the opening that is used to install pencil at the front end of gun barrel, be shaped on the bayonet socket that is used to block the made groove of pencil outer rim at the leading section of gun barrel.

And the rear end hinge of said driving lever is contained in the handle, and the middle part of driving lever connects an extension spring, and made fore-set triggers institute's dress switch in the handle on the driving lever, and said motor is communicated with external or built-in power.

The advantage and the good effect of this utility model are:

This utility model is simple in structure, and the front end of gun barrel clamps pencil, move driving lever after, make motor rotation, motor promotes push rod through slowing down after, the piston that the top rod driving pencil is interior, the propelling movement of piston completion medicine.The whole process state that remains a constant speed, rapid speed not only, and can not cause the discomfort of sufferer.
