Abstract
The utility model relates to a spiral pushing aid and spiral advancing injector. A spiral pushing aid which comprises a sleeve barrel, a connecting cylinder, a screw rod and a hand wheel is used to cooperate with the existing spiral advancing injector to reach the goal of time-saving and labor-saving of injection and easy controlling of injection speed. A spiral advancing injector which comprises a needle cylinder and a piston is added to a pushing aid cylinder which is occlusive with the screw threads on the outside of the needle cylinder to reach the goal of time-saving and labor-saving of injection and easy controlling of injection speed.
Description
This utility model relates to spiral booster and screw propulsion syringe.
Conventional injector all adopts axial advance.When using the larger capacity syringe, operation is effort very.According to survey, need about 100 newton's thrust when carrying out intravenous injection with the syringe more than 50 milliliters, this is a very tiring job to the medical worker.Do not do a good job and also can affect the treatment.
The purpose of this utility model is that novel injector will be provided, and it can overcome the deficiency of existing syringe, and is laborsaving when reaching injection, can arbitrarily control the purpose of injection speed.
The purpose of this utility model is to realize like this.Utilize spiral principle to reach laborsaving, change former axial propelling into screw propulsion.Based on this total inventive concept, following two kinds of utility models are proposed.Be further described below in conjunction with accompanying drawing.
Fig. 1 is the longitudinal profile sketch map of a kind of existing axial advance syringe and spiral propeller.
Sleeve (3) and connecting cylinder (4) are two parts, are one but can they be revolved by screw thread.In connecting cylinder (4) bottom a screw rod (5) is arranged.The interior stricture of vagina interlock of the same connecting cylinder of the outer stricture of vagina of screw rod (5) (4), screw rod (5) end is fixed a handwheel (6), and rotation hand wheel (6) can drive screw rod (5) and move forward and backward.Earlier sleeve (3) is enclosed within on the injector syringe (1) in use, again connecting cylinder (4) is screwed on the sleeve (3).By handwheel (6) with screw rod (5) thus screw in promoting piston (2) injects.All available rustless steel of whole spiral propeller or duroplasts are made.The length of screw rod (5) is shifting piston (2) onto syringe (1), and the top is a principle.
Fig. 2 is a kind of screw propulsion syringe longitudinal profile meaning diagrammatic sketch.Wherein (1) is syringe, and (2) are piston, and (3) are the boosting tube.The screw thread that mutual interlock is arranged at the terminal outer wall of syringe (1) and boosting tube (3) inwall.Rotation boosting tube (3) just can promote piston (2).Syringe (1), piston (2) useable glass are made.Boosting tube (3) available metal, or non-toxic duroplasts makes, and its female thread length is principle with the top that piston (2) can be shifted onto syringe (1).
Not only above-mentioned two kinds of the worth utility model that is based on inventive concept that proposes.
This utility model has solved with existing axial advance syringe and has injected the difficulty of particularly carrying out the intravenous injection effort, and is easy to control the injection speed when injecting.An embodiment as screw propulsion syringe shown in the accompanying drawing 1.Syringe (1) adopts 50 * 60 double threads with the screw thread of boosting tube (3) phase interlock, if piston (2) axial thrust needs 100 newton, then only needs to apply about 5 newton's torsion on boosting tube (3).
Claims (3)
1, spiral booster and screw propulsion syringe comprise syringe, and piston is characterized in that the spiral booster by sleeve, connecting cylinder, and screw rod, handwheel is formed.Can revolve by screw shell and connecting cylinder and to be one, handwheel is fixed in the screw rod end, and screw rod and connecting cylinder are with threaded engagement.
2, spiral booster and screw propulsion syringe comprise syringe, and piston is characterized in that the screw propulsion syringe has a boosting tube and the syringe end outside with threaded engagement.
3, according to claim 1, it is characterized in that: whole spiral booster all can be made by rustless steel or duroplasts.
