Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a disposable negative pressure type liquid converter comprises a bottle body 1, the bottle body 1 is made of medical soft materials and has certain toughness, after the bottle body 1 is extruded, the bottle body 1 can restore deformation, when the bottle body 1 is extruded, gas in the bottle body 1 is discharged through a one-way valve 4 and a needle head 3, then the needle head 3 is inserted into external liquid, extrusion force on the bottle body 1 is removed, at the moment, when the bottle body 1 restores deformation, external liquid is pumped into the bottle body 1 through negative pressure in the bottle body 1, a cover body 2 is arranged at the top of the outer wall of the bottle body 1, the cover body 2 is matched with the bottle body 1, the needle head 3 is convenient to replace, the inner wall of the cover body 2 is in threaded connection with the top of the outer wall of the bottle body 1, the needle head 3 is arranged above the cover body 2, the cover body 2 penetrates through the cover body 2 below the outer wall of the needle head 3, the cover, setting of check valve 4, make the unable inside that gets into bottle 1 of external gas, and when syringe needle 3 inserts the inside of external container, the gas of 1 inside of bottle can discharge, deformation through bottle 1, produce the negative pressure, and then pass through the inside of 3 suction bottles 1 of syringe needle with external liquid, check valve 4 and lid 2 inside to the intercommunication, the outer wall processing of bottle 1 has scale 5, scale 5 person of facilitating the use observes the volume of 1 inside liquid of bottle, the outer wall processing of lid 2 has the wear line, the length of syringe needle 3 is 2-3 centimetres, lid 2 agrees with mutually with 1 laminating department of bottle.

When using this disposable negative pressure formula liquid converter, the extrusion bottle 1, 1 inside gas of bottle passes through check valve 4 and syringe needle 3 discharges, later insert the inside of external liquid with syringe needle 3, remove the extrusion force to bottle 1, at this moment when bottle 1 self resumes deformation, through the inside negative pressure of its inside with external liquid suction bottle 1 right inside, check valve 4's setting, make external gas can't get into the inside of bottle 1, and when syringe needle 3 inserts the inside of external container, the inside gas of bottle 1 can discharge, make things convenient for medical personnel to observe the inside liquid volume of bottle 1 through scale 5, when needs change syringe needle 3, can rotate lid 2, make lid 2 and bottle 1 separate, later more change new lid 2, can realize changing syringe needle 3, the operation of giving medical personnel brings the convenience.
