Abstract
The utility model relates to a medical tympanic cavity injector, in particular to a medical tympanic cavity injection and absorption apparatus in an E.N.T. department. The medical tympanic cavity injector is formed in the way that one end of an injection needle tube is connected with a puncture needle, the other end of the injection needle tube is connected with a steering joint, a tube core is arranged in the injection needle tube, one end of a rubber skin tube is connected with the steering joint, and the other end of the rubber skin tube is connected with a rubber ball. When the medical tympanic cavity injection and absorption apparatus is in use, a person uses a single finger to hold the injection needle tube and uses the palm center to control the rubber ball, the tube core moves in the injection needle tube back and forth by extruding the rubber ball and with the help of the self tension of the rubber ball, so the goals of liquid medicine injection or effusion suction are achieved. The utility model has the advantages of simple structure, convenient operation, safety, reliability, single hand operation, clear visual field, easy fixation of puncture needle, low cost and high work efficiency, and is widely used in the E.N.T. department.
Description
Technical field:
This utility model relates to the medical tympanum injection aspirator of a kind of medical tympanum injection aspirator, particularly department of otorhinolaryngology tool equipment.
Background technology:
At present, the available technology adopting ordinary syringe is aspirated intratympanic hydrops and to the Injection in Tympanic Cavity medicinal liquid, bimanualness, block doctor's sight line, the inserting needle depth is difficult for grasping, and crosses dark damage tympanum inner structure, piercing needle is difficult to fixing, often cause inserting needle to cross dark or slippage, particularly the patient's operation to psychentonia is difficult more, can finish so this operation generally needs the doctor of certain clinical experience.
Summary of the invention:
The purpose of this utility model, provide a kind of medical tympanum injection aspirator, it is the shortcoming that overcomes above-mentioned existence, and a kind of one-handed performance of design, another hands tractive auricle is broadened one's vision, the medical tympanum injection aspirator that punctures in the fixing head position, it is to be connected with injection needle by piercing needle, device tube core in the injection needle, and steering knuckle is connected with the injection needle other end, rubber leather hose one end connects steering knuckle, and the rubber leather hose other end connects rubber bulb and constitutes.One hand refers to hold injection needle during operation, and the centre of the palm is held rubber bulb, and the extruding rubber bulb by the tension of rubber bulb, moves forward and backward tube core during suction during injection liquid in injection needle, thereby reaches the purpose of injection and suction.
The medical tympanum injection aspirator of this utility model takes following technical scheme to realize, it is to connect piercing needle by injection needle one end, the injection needle other end connects steering knuckle, device tube core in the injection needle, rubber leather hose one end connects steering knuckle, and the rubber leather hose other end connects rubber bulb and constitutes.One hand refers to hold injection needle during operation, centre of the palm control rubber bulb, and self tension force by extruding rubber bulb and rubber bulb moves forward and backward tube core, thereby reaches the purpose of liquid medicine injection or suction hydrops in injection needle.
The effect of the medical tympanum injection aspirator of this utility model is simple in structure, and is easy to operate, safe and reliable, and one-handed performance gets a clear view, and puncture needle is easily fixing, and cost is low, and high efficiency is widely used in otorhinolaryngologic medical apparatus and instruments.
Description of drawings:
The medical tympanum injection aspirator of this utility model will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the medical tympanum injection aspirator of this utility model.
1---piercing needle 2---injection needle 3---tube core 4---rubber bulb 5---steering knuckle 6---rubber leather hose
The specific embodiment:
With reference to accompanying drawing, the medical tympanum injection aspirator of this utility model, it is to connect piercing needle 1 by injection needle 2 one ends, injection needle 2 other ends connect steering knuckle 5, device tube core 3 in the injection needle 2, rubber leather hose 6 one ends connect steering knuckle 5, and rubber leather hose 6 other ends connect rubber bulb 4 and constitute.During operation, when drawing liquid, push rubber bulb 4 earlier, make it to be in the state that partly rises, again injection needle 2 is screwed into steering knuckle 5, thumb food middle finger is held injection needle 2, piercing needle 1 is thrust tympanum, and palm control rubber bulb 4 slowly loosens, and liquid is promptly slowly extracted out, when injection liquid or notes filtrated air, medicinal liquid or filtrated air are sucked in the injection needle 2, after piercing needle 1 thrusts tympanum, extruding rubber bulb 4, medicinal liquid or filtrated air promptly slowly inject, suction is grasped according to injection needle 2 high scales with injection rate, can take out tube core 3 flushings behind the end of operation, does routine disinfection.
The embodiment of the medical tympanum injection aspirator of this utility model, it is to connect piercing needle 1 by injection needle 2 one ends, the other end connects steering knuckle 5, device tube core 3 in the injection needle 2, rubber leather hose 6 one ends connect steering knuckle 5, and the other end connects rubber bulb 4 and constitutes.On the injection needle 2 scale is set, according to specific circumstances liquid medicine injection or suction hydrops.One-handed performance during use gets a clear view, and puncture needle is easily fixing, simple to operation, grasps easily, and cost is low, and high efficiency has solved the inconvenience that traditional bimanualness brings, and is widely used in otorhinolaryngologic therapeutic equipments.
