Abstract
The utility model relates to an injector with controllable injection depth, which consists of a needle head, an injection tube, an injection piston, an adjusting outer sleeve, threads and a scale mark, wherein the structure of the needle head, the injection tube and the injection piston is basically identical to that of an ordinary injector, and is characterized in that the periphery of the injection tube is provided with threads, and the middle of the injection tube is provided with the scale mark; and the adjusting outer sleeve is of a cylinder with the diameter being slightly more than that of the injection tube, and the front end of the adjusting outer sleeve is provided with a circular hole, and the needle head extends out of the circular hole, and the inner side on the rear end of the adjusting outer sleeve is provided with a thread which is consistent with that on the periphery of the injection tube, and the adjusting outer sleeve is fixed outside the injection tube through screw threads, so that by aligning the line on the rear end of the adjusting outer sleeve to the scale mark of the injection tube, the depth of the needle pin which extends out of the circular hole on the front end of the adjusting outer sleeve can be read. The injector has simple structure, convenient application, safety, reliable and low cost, and can be widely popularized for use.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of syringe of controlled injection depth.
Background technology
Intramuscular injection is the modal operating technology of nursery work, because muscle is better to the medicine irritation toleration, fleshiness, trunk, nerve trunk are less, and abundant capillary network and lymph pipe network are arranged, and very fast to drug absorption, have characteristics safe, convenient, instant effect, easily being accepted by patient, is ideal route of administration.In clinical various medicine injections, use at most with the buttocks intramuscular injection.Although intramuscular injection is in the history in existing more than 100 year of clinical practice, its complication occurs repeatedly, and has caused medical personnel's attention.How just can avoid the generation of the various complication of gluteal muscle, reach effective therapeutic effect, the medical expert has done the demonstration of science to injection depth, injection site.Except correct selection injection site, more to accurately grasp injection depth.
Summary of the invention
This utility model overcomes the deficiency that above-mentioned technology exists, and a kind of novel control syringe that can accurately control injection depth is provided.This utility model can be according to injectable drug different or injection subject's body difference accurately control injection depth, effectively prevent and reduce the generation of complication such as subcutaneous scleroma.
The technical solution of the utility model is: a kind of syringe of controlled injection depth, comprise by syringe needle, injection tube, injection ram, adjustment overcoat, screw thread, graduation mark and forming, the structure composition and the ordinary syringe of syringe needle of the present utility model, injection tube, injection ram are basic identical, its difference is that the periphery of injection tube is provided with screw thread, and the centre is provided with a graduation mark; Regulating overcoat is that a diameter omits large cylinder than injection tube, its front end has circular hole, syringe needle leans out from circular hole, the inboard of regulating the overcoat rear end is provided with the screw thread consistent with the injection tube outer periphery threads, regulating overcoat is fixed on outside the injection tube by screw thread, by regulating the scale of the corresponding injection tube graduation mark of overcoat back end of line institute, can read the length that syringe needle is leant out from adjusting overcoat front end circular hole.
When using this utility model, to regulate overcoat is screwed on the injection tube, according to the injectable drug property of medicine and the definite degree of depth that will inject of patient body practical situation, regulate overcoat by threaded adjustment, the length that syringe needle is leant out just meets the degree of depth that the patient will inject, the degree of depth that the medical worker just can fine assurance injection like this, thus avoided traditional injecting method liquid medicine injection major part to be positioned at the consequence that local bad result that fat deposit brings and drug effect reduce.
This utility model is simple in structure, esy to use, safe and reliable, cheap, can extensively promote the use of.
Description of drawings
Accompanying drawing is this utility model structural representation.
Wherein: 1, syringe needle 2, injection tube 3, injection ram 4, adjustment overcoat 5, screw thread 6, graduation mark
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, as shown in the figure, a kind of syringe of controlled injection depth, comprise by syringe needle 1, injection tube 2, injection ram 3, adjustment overcoat 4, screw thread 5, graduation mark 6 and forming, the structure composition and the ordinary syringe of syringe needle 1 of the present utility model, injection tube 2, injection ram 3 are basic identical, its difference is that the periphery of injection tube 2 is provided with screw thread 5, and the centre is provided with a graduation mark 6; Regulating overcoat 4 is diameter cylinders more bigger than injection tube, its front end has circular hole, syringe needle 1 leans out from circular hole, the inboard of regulating overcoat 4 rear ends is provided with the screw thread consistent with injection tube outer periphery threads 5, regulating overcoat 4 is fixed on outside the injection tube 2 by screw thread, by regulating the scale of the corresponding injection tube 2 high scale lines 6 of overcoat 4 back end of line institute, can read the length that syringe needle 1 is leant out from adjusting overcoat 4 front end circular holes.During use, will regulate overcoat 4 and be screwed on the injection tube 2, and adjust and regulate overcoat 4, the length that syringe needle 1 is leant out just meets the degree of depth that the patient will inject.
