[detailed description of the invention]
Below in conjunction with accompanying drawing, this utility model is described in further detail:
See Fig. 1 a and Fig. 1 b, a kind of perforator preventing coming off, comprises perforator body, and perforator body is provided with tip 11, the anti-drop device 12 preventing perforator from coming off and perforator catch 13; Perforator body interior is provided with medicinal liquid runner 18 and air duct 19, is provided with the imbibing hole and steam vent that are communicated with medicinal liquid runner 18 and air duct 19 respectively on most advanced and sophisticated 11; Air duct 19 is communicated with the exhaustor connector 15 being arranged on perforator body afterbody.
As shown in Figure 2, anti-drop device 12 is arranged in the intrinsic operating cavity of perforator, comprises spring leaf, button 14 and spring 16, and on spring leaf, homonymy is provided with the first convex body 20 and the second convex body 21; First convex body 20 is reverse V-shaped, M type, inverted U or circular arc type.Spring leaf suppressed by spring 16, and perforator outer wall 17, second convex body 21 that the first convex body 20 of spring leaf passes most advanced and sophisticated 11 passes perforator body afterbody and is connected with button 14.Spring leaf is two, is symmetricly set on perforator body both sides.Spring 16 is arranged on the junction between the first convex body 20 and the second convex body 21.The position that first convex body 20 passes tip 11 is arranged between perforator catch 13 and imbibing hole.First convex body 20 and most advanced and sophisticated 11 contact positions are provided with the silica gel piece of liquid-leakage preventing, prevent medicinal liquid from entering in the intrinsic operating cavity of perforator, cause unnecessary waste.
As shown in Figure 3, a kind of transfusion device preventing coming off, the perforator 1 comprised, and top hose 3, dropping funnel 5, bottom hose 6, liquid medicine filter 8 and the transfusion needle 9 to be connected successively with perforator 1, exhaustor connector 15 connects exhaustor 2, and top hose 3 arranges side pipe, side pipe is arranged latex cap 4; Bottom hose 6 is arranged flow control valve 7; During use, perforator 1 pierces through the bottle stopper of transfusion bag or infusion bottle, and bottle stopper is between anti-drop device 12 and perforator catch 13.
Operation principle of the present utility model is: when perforator 1 pierces through the bottle stopper of transfusion bag or infusion bottle, under the squeezing action of bottle stopper, the first convex body 20 times pressing springs of spring leaf, while spring energy-storage, spring leaf entirety retracts in the intrinsic operating cavity of perforator, perforator 1 just can pierce through bottle stopper, and most advanced and sophisticated 11 are inserted into transfusion bag or infusion bottle inside.Owing to releasing energy after the energy storage of spring, tip 11, first convex body 20 that the first convex body 20 ejects perforator 1 just can block bottle stopper, prevents perforator 1 nature or common External Force Acting from causing dropping.Play the object preventing from coming off.When extracting, pressing button 14, spring leaf and spring retraction, be easy to extract perforator.Medicinal liquid enters from medicinal liquid runner 18, flows into perforator 1, and air enters transfusion bag or infusion bottle inside from air duct 19 simultaneously, ensures enough pressure equilibrium.Other effects are identical with common transfusion device effect.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for this utility model person of an ordinary skill in the technical field; under the prerequisite of not isolating this utility model design; some simple deduction or replace can also be made, all should be considered as belonging to this utility model by submitted to claims determination scope of patent protection.
