Abstract
The invention discloses a disposable continuous fixed quantity injector. The external rear end of an injector tube is connected with a handle; a piston rod for injecting medicine is arranged in the injector tube; a thrust plate spring, a thrust plate, a guide sleeve, a braking spring and a braking handle are arranged on the piston rod outside the injector needle in one step; a location-limiting plate is arranged outside the braking spring between the guide sleeve and the braking handle; the guide sleeve and the location-limiting plate are connected above the handle; the hollow handle is internally provided with a pull handle shaft; a pull handle is arranged on the pull handle shaft in the hollow handle; and the upper end of the pull handle leans against the lower end of the thrust plate. The disposable continuous fixed quantity injector saves labor and is convenient for the continuous fixed quantity injection operation discontinuously. When in use, the handle is grasped by one hand, and the pull handle is pulled and moves forward to push the piston rod for injection; when the pull handle touches a shifting lug, the injection is stopped and the fixed quantity injection is finished. If one more continuous fixed quantity injection is needed, the pull handle is directly pulled again and the one more continuous fixed quantity injection with interruption is finished without other operations.
Description
Technical field
The invention belongs to injector for medical purpose, particularly a kind of disposable continuous fixed quantity injector.
Background technology
The medical at present syringe that uses can not be according to the administration of clinical requirement accurate quantification, and need and squeezing with fingerhold of needle tube type syringe push away, and needs bigger exerting oneself.Calibrated shot need come the positioning retainer ring on the mobile putter to come quantitatively with hands, and one-time positioning can only calibrated shot once, carry out once quantitative injection if desired continuously again, just need the reuse hands to move the one-time positioning back-up ring, like this can not the successive continual calibrated shot that carries out again a time.In the radiography operation, during doctor's calibrated shot contrast agent, often not once that the image situation of radiography needs continuously calibrated shot one or many contrast agent again, up to reaching best radiography effect according to the observation.Use general syringe, very inconvenient, can not realize the calibrated shot of continuous several times.
Summary of the invention
Technical problem to be solved by this invention is: a kind of disposable continuous fixed quantity injector is provided.Can realize the calibrated shot of continuous several times, easy-to-use, and laborsaving.
Technical scheme of the present invention is:
A kind of disposable continuous fixed quantity injector, it is characterized in that: the outer rear end of needle tubing connects lever, the piston rod that pushes away medicine is housed in the needle tubing, and the last time of staying the outer piston rod of needle tubing is equipped with pushing plate spring, pushing plate, fairlead, tripping spring and brake handle; Outside the tripping spring between fairlead and brake handle limiting plate is arranged, fairlead and limiting plate are connected the lever top, pull handle in the lever of hollow, axle, pull handle and be contained in pulling on the Handle axis in the lever of hollow, pull the lower end that the handle upper end abuts against pushing plate.
In the lever of hollow selector shaft is arranged, connect the gear shift nose bar on the selector shaft, selector shaft has the gear shift knob outside the lever of hollow; The groove that matches with the gear shift nose bar is arranged pulling on the handle.
In the lever of hollow selector shaft is arranged, connect shifting cam on the selector shaft, selector shaft has the gear shift knob outside the lever of hollow; The groove that matches with shifting cam is arranged pulling on the handle.
The hole that is a bit larger tham the piston rod external diameter is arranged on the pushing plate, and piston rod is through that this is a bit larger tham in the hole of piston rod external diameter on the pushing plate.
The hole that is a bit larger tham the piston rod external diameter is arranged on the brake handle, and piston rod is through that this is a bit larger tham in the hole of piston rod external diameter on the brake handle.
Effect of the present invention is:
Use disposable continuous fixed quantity injector laborsaving, be convenient to operation, can be successive easily the operation of interruption calibrated shot, its injection pressure is greater than the pressure of the syringe of in the past finger push.As long as one holds lever, pull handle during use, pull handle and promote piston rod forward, inject, stop injection when handle is run into the gear shift nose bar, reach calibrated shot when pulling.When also needing continuously again calibrated shot, directly pull handle again and get final product, mustn't cooperate other operations can reach interruption calibrated shot again continuously.Owing to the effect of brake handle, piston rod can only move to the syringe needle direction, can not retreat, and sucks medicinal liquid if desired in needle tubing at ordinary times, as long as press brake handle, the pulling piston rod just can retreat piston rod, at this moment just medicinal liquid can be sucked in the needle tubing from syringe needle.Behind the loosen the brake handle, piston rod just can not retreat.

The specific embodiment
As scheme a kind of disposable continuous fixed quantity injector, the outer rear end of needle tubing 1 connects lever 10, the piston rod 2 that pushes away medicine is housed in the needle tubing, and the last time of staying the outer piston rod of needle tubing is equipped with pushing plate spring 5, pushing plate 3, fairlead 6, tripping spring 8 and brake handle 7; The hole that is a bit larger tham the piston rod external diameter is arranged on the pushing plate, and piston rod is through that this is a bit larger tham in the hole of piston rod external diameter on the pushing plate.The hole that is a bit larger tham the piston rod external diameter is arranged on the brake handle, and piston rod is through that this is a bit larger tham in the hole of piston rod external diameter on the brake handle.
Limiting plate 9 is arranged outside the tripping spring between fairlead and brake handle, fairlead and limiting plate are connected the lever top, pull handle 4 in the lever of hollow, pull interior the pulling on the Handle axis 16 of lever that handle is contained in hollow, pull the lower end that the handle upper end abuts against pushing plate.
Selector shaft 11 is arranged in the lever of hollow, connect gear shift nose bar 12 on the selector shaft, selector shaft has gear shift knob 15 outside the lever of hollow; Pull have on the handle match with the gear shift nose bar pull handle grooves 13.
Selector shaft 11 is perhaps arranged in the lever of hollow, connect shifting cam 14 on the selector shaft, selector shaft has gear shift knob 15 outside the lever of hollow; Pull have on the handle match with shifting cam pull handle grooves 13.
