Technical Field

The utility model relates to a medical accessory field specifically is an electrocardio lead line junction snap-fastener tensile device.

Background

The Electrocardiogram (ECG) is the most effective means for observing, diagnosing and analyzing the heart function state of a patient at present, and the electrocardiograph is used as a main tool for drawing the electrocardiogram, is simple and convenient to operate, has moderate price, and is one of the most popular medical electronic instruments in hospitals at all levels.

The production process flow of each patient end connector comprises the steps of carrying out tin immersion on the tail end of each sub-core wire A1, adding tin on a snap fastener B, welding the tail end of the tin-immersed sub-core wire A1 at the center or the lower position of the center of the snap fastener B (the position of △ adding tin), then forming an inner mold, installing an inner membrane shell as shown in a2/B2 in the figure 3, and further forming an outer membrane shell as shown in A3/B3 in the figure 3, so that the patient end connectors of the existing lead wires are produced by adopting a production mode that the sub-snap fasteners are welded on the sub-core wires, and the products produced by the production mode have the defects of insufficient tension, easy breaking and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an electrocardio lead line junction snap-fastener tensile device, it can effectively solve the product pulling force not enough, easily brokenly easily rolls over the scheduling problem, about promoting product snap-fastener electrode pulling force to 16kgf from about 8kgf, the pulling force has promoted about the twice, the snap-fastener electrode sways the number of times and has promoted about 20000 times from 5000 times, the effectual easy problem of rolling over of having solved easily absolutely.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides an electrocardio lead wire junction snap-fastener tensile device, includes anti pull ring, tensile ring one end is equipped with along radial convex wing dog, tensile ring other end middle part is equipped with along the convex joint dog of axial.

The anti-pulling ring is made of brass gold plating.

Contrast prior art, the beneficial effects of the utility model reside in that:

after the inside copper wire filament of heart yearn A1 one end and snap fastener B welded, set up anti pull ring through the crimping on the outer insulating skin at heart yearn A1, realize spacing joint between the wire inlet port of anti pull ring and interior membrane shell, can restrict including in the membrane shell after the pull ring is spacing and rotate, also can restrict and remove about to play better tensile, anti twisting effect. Therefore, the problems of insufficient product tension, easy breakage and easy breaking and the like can be effectively solved through the technology. Through experimental analysis, the pulling force of the snap button electrode of the product can be lifted to about 16kgf from about 8kgf, the pulling force is lifted by about two times, the swinging frequency of the snap button electrode is lifted to about 20000 times from about 5000 times, and the problem that the snap button electrode is easy to break and break is effectively solved.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

An electrocardio line junction snap-fastener tensile device that leads, major structure include anti pull ring 1, 1 one end of anti pull ring is equipped with along radial convex wing dog 2, 1 other end middle part of anti pull ring is equipped with along axial convex joint dog 3. The anti-pulling ring 1 is made of brass and gold plating. The wall thickness of this device is 0.5mm, and long 4.2mm, height 3.54 mm.

The using method comprises the following steps:

after the inner copper wire at one end of the sub-core wire a1 is welded to the snap fastener B, the tension ring 1 is crimped and disposed on the outer insulating sheath of the sub-core wire a1, as shown in fig. 2 and 4 of the drawings attached to the specification.

Spacing joint is realized through wing dog 2, joint dog 3 between anti pull ring 1 and the inlet wire port 5 of inner membrance shell 4, and anti pull ring 1 is spacing can restrict in inner membrance shell 4 after rotating, also can restrict and remove to play better tensile, anti wrong effect.

Therefore, the problems of insufficient product tension, easy breakage and easy breaking and the like can be effectively solved through the technology. Through experimental analysis, the pulling force of the snap button electrode of the product can be lifted to about 16kgf from about 8kgf, the pulling force is lifted by about two times, the swinging frequency of the snap button electrode is lifted to about 20000 times from about 5000 times, and the problem that the snap button electrode is easy to break and break is effectively solved.
