Description
Technical field
This utility model relates to medical instruments field, especially a kind of automatic vent syringe.
Background technology
The appearance of syringe is the once epoch-making revolution of medical instruments field, in order to a small amount of drug injection in body, thus reach and recover the object of normal vital signs.Syringe is generally made up of the foraminate syringe of front end band and the piston push rod that matches, by promoting push rod thus being pushed in body by medicinal liquid.In injection process, when medicinal liquid is pumped to syringe from medicine bottle, more or less can with portion of air, these air are present in syringe with the form of bubble, if once by these gas injections in trachea, air will be caused to fasten the consequence of plug, air will enter blood circulation, until to pulmonary, hinders pulmonary artery major avenues of approach, cause serious shock, therefore by injecting liquid drug to human body time before, often by syringe be inverted, beat gently, then extrude some medicinal liquids, thus the air in syringe is discharged.But this method not only wastes a certain amount of medicinal liquid, and can only discharge section air, can not be drained, easily malpractice be occurred.
Utility model content
Technical problem to be solved in the utility model is: the defect that can not drain air in medicinal liquid in order to overcome existing syringe, provides a kind of automatic vent syringe.
This utility model solves the technical scheme that its technical problem adopts: the push rod comprising syringe, be set in the needle tubing of syringe end and be arranged in syringe, described push rod end is provided with plug, described plug coordinates with syringe movable sealing, plug and syringe end shape adapt, described plug offers some through holes, auxiliary push-rod is slidably connected in this through hole each, described auxiliary push-rod end winding support is connected with the venting plug that medicinal liquid can be allowed to pass through, described venting plug is placed in the sealed cavity that syringe end and plug form, and venting plug coordinates with syringe movable sealing; During use, pump medicinal liquid in syringe, then promote auxiliary push-rod, auxiliary push-rod drives venting plug to advance, until syringe end, thus is discharged by air.
Further, in order to allow medicinal liquid by venting plug, described venting plug offers some steam vents, the size of steam vent is less than bubble size, stops bubble by steam vent, thus by bubble destruction, squeezes out air.
In order to more thoroughly discharge the air in syringe, described venting plug and syringe end shape adapt.
Further, the through hole that described plug is offered has 4, and described auxiliary push-rod has 4, and the other end of each auxiliary push-rod is fixed to one another, and can realize retreating simultaneously.
The beneficial effects of the utility model are: the automatic vent syringe that this utility model provides, improves the structure of conventional syringe, by setting up venting plug in plug front end, by promoting venting plug, the air in syringe is discharged, structure is simple, and easy to operate, the scope of application is extensive.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the new automatic vent syringe of this practicality;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 be in Fig. 1 B-B to sectional view.
In figure: 1, syringe, 2, needle tubing, 3, push rod, 4, plug, 5, auxiliary push-rod, 6, venting plug, 6-1, steam vent, 7, sealed cavity.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in detail now.This figure is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with this utility model.
With reference to shown in Fig. 1, automatic vent syringe of the present utility model, comprise syringe 1, the needle tubing 2 being set in syringe 1 end and the push rod 3 be arranged in syringe 1, described push rod 3 end is provided with plug 4, described plug 4 coordinates with syringe 1 movable sealing, plug 4 and syringe 1 end shape adapt, described plug 4 offers some through holes, auxiliary push-rod 5 is slidably connected in this through hole each, described auxiliary push-rod 5 end winding support is connected with the venting plug 6 that medicinal liquid can be allowed to pass through, described venting plug 6 is placed in the sealed cavity 7 that syringe 1 end and plug 4 form, venting plug 6 coordinates with syringe 1 movable sealing, during use, pumped by medicinal liquid in syringe 1, then promote auxiliary push-rod 5, auxiliary push-rod 5 drives venting plug 6 to advance, until syringe 1 end, thus is discharged by air.
Further, with reference to shown in Fig. 2, in order to allow medicinal liquid by venting plug 6, described venting plug 6 offers some steam vent 6-1, air is present in syringe 1 with the form of bubble, and the size of steam vent 6-1 is less than the size of bubble.
With reference to shown in Fig. 1, in order to more thoroughly discharge the air in syringe 1, described venting plug 6 adapts with syringe 1 end shape.
Concrete, shown in Fig. 1 Fig. 3, the through hole that described plug 4 is offered has 4, and described auxiliary push-rod 5 has 4, and the other end of each auxiliary push-rod 5 is fixed to one another, and can realize retreating simultaneously.
The use procedure of this utility model automatic vent syringe is described: insert in medicinal liquid bottle by needle tubing 2 referring to Fig. 1, synchronously pull out push rod 3 and auxiliary push-rod 5, medicinal liquid is sucked in syringe 1, inwardly promote auxiliary push-rod 5 to syringe 1 front end afterwards, medicinal liquid passes through from the venting plug 6 of auxiliary push-rod 5 front end, thus is discharged by the air in syringe 1 when not extruding medicinal liquid.
The automatic vent syringe that this utility model provides, improves the structure of conventional syringe, and by setting up venting plug 6 in plug 4 front end, discharged by the air in syringe by promoting venting plug 6, structure is simple, and easy to operate, the scope of application is extensive.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff not departing from scope of the present utility model, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
