Abstract
The utility model discloses a device that prevents the syringe needle from falling off. The device comprises a hollow sleeve and a positioning inner sleeve connected with the hollow sleeve. The cavity of the hollow sleeve is provided with a conical clasp and the outer edge of the front of the positioning sleeve is provided with a convex step. The utility model has the advantages that the utility model is smart in design, easy to produce, convenient to operate and secure and needle insertion is quick and accurate, which makes the utility model a perfect assistant apparatus for injection of mentally manic patients.
Description
Technical field this utility model belongs to technical field of medical instruments, relates to a kind of injection needle anti-dropping device.
Background technology is present, and is clinical when injecting for the hot-tempered noisy psychotic of impulsion, because its incompatibility, the injection location is difficult to control, usually control the degree of depth of injecting inserting needle by the injection personnel with finger, complex operation and depth of needle are inaccurate, can only probably estimate; In addition, inserting the back syringe needle can cause instability with the swing of injection object, the situation that syringe needle fractures often occurs, and syringe needle easily comes off during the withdraw of the needle, causes drug waste, does not reach sanatory effect.In case the syringe needle of dialysis is stayed in the muscle, will hardly imaginable consequence take place.
The summary of the invention the purpose of this utility model provides and a kind ofly can position injection to the hot-tempered noisy psychotic that gets excited accurately and effectively, and syringe needle can not break away from needle tubing all the time, guarantees the injection needle anti-dropping device of injection safety, to overcome the deficiencies in the prior art.
This utility model injection needle anti-dropping device, it constitutes by overlapping in the sleeve of interior sky and the connected location, and the barrel bore front portion is provided with the taper bayonet socket, and the external margin of cover front end is provided with the step of evagination in the location.
The surperficial relevant position of cover indicates graduation mark respectively in said sleeve and the location; The forward and backward position of sleeve lining is fixed with O shape cushion rubber respectively; Cartridges sides is provided with observation window.
Grip for the ease of hands, said telescopic slotting arrival end is provided with annular end cap.
This utility model modern design, be easy to make, easy to operate, safety, inserting needle is quick, accurate, is a kind of comparatively ideal auxiliary implement to the hot-tempered noisy psychotic's injection of getting excited, can extensively promote the use of.
Description of drawings Fig. 1 is the decomposing schematic representation of this utility model structure;
Fig. 2 is the matching used state reference map of this utility model and syringe.
The specific embodiment is with reference to Fig. 1, Fig. 2, and this utility model injection needle anti-dropping device is made of cover 1 in the sleeve 2 of interior sky and the connected location; Sleeve 2 inner chamber front portions are provided with taper bayonet socket 6, and the external margin of cover 1 front end is provided with the step 7 of evagination in the location; The surperficial relevant position of cover 1 indicates graduation mark 9 respectively in sleeve 2 and the location; The forward and backward position of sleeve 2 inwalls is fixed with O shape cushion rubber 5 respectively; Sleeve 2 sides are provided with observation window 3; The slotting arrival end of sleeve 2 is provided with annular end cap 4.
During use, syringe is inserted in this utility model injection needle anti-dropping device, cover 1 in the rotation location is regulated the mutual alignment of itself and sleeve 2, by its graduation mark that indicates 9, the inserting needle depth of syringe needle is adjusted and positioning control.Adjusting finishes, i.e. injectable.When syringe needle punctured in the hot-tempered noisy psychotic's muscle of impulsion, the preceding transverse plane 8 of step 7 pressed patient's human body, because contact area strengthens, can guarantee the stability of injecting, and no matter how restless the patient is, syringe needle can not break away from needle tubing yet.
