Abstract

The invention discloses a medical ampoule mouth gag, which consists of an ampoule neck clamp, a rotating cutter and a spring tip. The ampoule neck clamp is a cavity column body and is used to clamp an ampoule neck. The rotating cutter is located at the lower end of the ampoule neck clamp and is used to cut the ampoule neck. The spring tip is fixed at the upper end of the ampoule neck clamp for pushing out an ampoule neck end in the cavity of the ampoule neck clamp. In the use process, the ampoule neck is extruded into the cavity of the ampoule neck clamp, the rotating cutter is rotated, one hand grasps an ampoule body while the other hand grasps the handle of the ampoule mouth gag, and the ampoule opening operation can be finished stably. The whole operation is safe, reliable and high efficient and saves labor.

Description

Medical ampoule mouth gag

Technical field

The present invention relates to a kind of medical ampoule mouth gag, directly apply to the opening operation of medical ampoule.

Background technology

The injection that needs of medical treatment are a large amount of extracts injection and at first will open ampoule.At present, in the medical practice, the opening operation of ampoule is finished with a carborundum sheet.Its process is: one holds ampoule body, takes the carborundum sheet on the other hand, delineates a circle with the carborundum thin slice on Ampoule neck, and then, one holds ampoule body, grabs the Ampoule neck upper end on the other hand, firmly breaks into two with one's hands, perhaps one holds ampoule body, takes metal bar to knock Ampoule neck on the other hand.There is following shortcoming in this mode:

1, easily pollutes injection, cause infusion reaction.Hand takes the carborundum sheet to draw circle on Ampoule neck, because not have fixing circle core shaft and fixing disc, " water clock ", " heavily quarter " often appear in delineation, simultaneously, " circle " of delineation is the on-plane surface circle, cause fracture uneven like this, the pole of figure is irregular, when causing these defectives, very easily produce glass chip, glass chip disconnects along fitfull, slips into injection, causes injection to pollute and infusion reaction.When particularly knocking Ampoule neck with metal bar, above-mentioned phenomenon is even more serious.

2, operation is dangerous, because the fracture irregular hurts finger easily when breaking off with the fingers and thumb with hand.

3, cause the injection liquid splash to run off easily, influence medical effect.

4, labour intensity is big, and psychological pressure is big, because both ampoule volume is little, neck is very thin, and smooth surface is directly broken off with the fingers and thumb gruelling, particularly difficult especially to women nurse with hand.Simultaneously, worry finger injuries, produce fear again, strengthened psychological pressure.

5, incisory carborundum thin slice because little and thin inconvenience deposits, is easily lost or is forgotten.

Summary of the invention

Technical matters to be solved by this invention provides a kind of injection, safety of operation, reliable, laborsaving, medical ampoule mouth gag efficiently of not polluting.

For solving the problems of the technologies described above, medical ampoule mouth gag of the present invention is made up of Ampoule neck anchor clamps, rotary cutter, thimble.The Ampoule neck anchor clamps are the cavity cylinder, and its cavity negative camber is imitative Ampoule neck curved surface.Its cylinder is split-type structural, by forming at the bottom of sandwich, sandwich adapter plate, barrel, the top cylinder.Sandwich is fixed on the barrel by adapter plate, and middle at the bottom of the top cylinder have a hole corresponding to Ampoule neck anchor clamps cavity curved surface upper end open place.

At Ampoule neck anchor clamps upper end fixed installation thimble.Thimble by barrel, doffing at the bottom of, big or small thimble forms.With overlapping at the bottom of the top cylinder of ampoule anchor clamps, structure is identical, size is corresponding at the bottom of the doffing, and little thimble is for falling " T " font, and the Kong Yuda thimble in the middle of at the bottom of the cavity that little thimble passes the Ampoule neck anchor clamps and the top cylinder is connected.So big or small thimble linkage moves up and down.

Rotary cutter is arranged in the lower end of Ampoule neck anchor clamps.Rotary cutter is made up of base body, suspension body, swivel eye, cutter.Base body plays a supportive role.Be fixed on the drum outer wall of Ampoule neck anchor clamps, suspension body is fixed on the swivel eye upper end, and cutter are fixed on the swivel eye lower end, and the three forms groove shape.The swivel card hangs on the base body, can make circular movement and drive cutter to make circular movement around Ampoule neck anchor clamps outer wall around Ampoule neck, in the corresponding cutter adjusting control handle that is furnished with of cutter, the cutting point of a knife is on the downward extensions of Ampoule neck anchor clamps cavity curved surface.

After adopting such structure, Ampoule neck is clamp-oned the cavity of Ampoule neck anchor clamps, the Ampoule neck upper end is pushed to thimble, one holds ampoule body, one holds swivel eye, presses down cutter adjusting control handle with finger, adjusts point of a knife to Ampoule neck, with Ampoule neck anchor clamps cylinder is fixing circle core shaft, is fixing disc with base body.Rotation, and drive point of a knife and make regular circular movement around Ampoule neck, and engrave one and iris wipe trace.Then, one holds ampoule body, and one holds barrel one breaks off with the fingers and thumb gently, so just can stably disconnect a regular opening on Ampoule neck, and not produce glass chip, reaches and does not pollute injection.Remove ampoule body, the thimble that press...withes one's finger is down released the Ampoule neck termination of staying in the Ampoule neck anchor clamps cavity.Because whole opening process is to finish in anchor clamps, avoided injury to finger, eliminated psychological pressure, reach safety requirements.Because with barrel double as handle, and arm of force lengthening, so more laborsaving, operate more stable, reliable.Be integrated into a continuous handling owing to draw round and break disconnected two operations off with the fingers and thumb to cutting, therefore saved the time, simultaneously owing to draw circle with rotary cutter cutting, hand rotates half cycle at most, and must rotate a circle with hand delineation operator originally, both compare, and rotary cutter can be saved the time of half.The integrated use of advantage factor such as safe, laborsaving, as to save time has greatly improved work efficiency, reaches target efficiently.

Description of drawings

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments

Accompanying drawing is the cutaway view of medical ampoule mouth gag of the present invention.

The specific embodiment

Shown in the accompanying drawing, medical ampoule mouth gag is made up of Ampoule neck anchor clamps [comprising (2) (4) (5) (6) (7)], thimble [comprising (1) (2) (3) (4)], rotary cutter [comprising (8) (9) (10) (11) (12)].
