Wartenberg Wheel
A Wartenberg wheel, also called a Wartenberg pinwheel or Wartenberg neurowheel, is a medical device for neurological use. The wheel was designed to test nerve reactions ( sensitivity) as it rolled systematically across the skin. A Wartenberg wheel is generally made of stainless steel with a handle of approximately in length. The wheel, which has evenly spaced radiating sharp pins, rotates as it is rolled across the flesh. A disposable plastic version is available. Because of hygienic concerns, these devices are rarely used for medical purposes. Robert Wartenberg, namesake of the Wartenberg wheel, is sometimes incorrectly credited as its inventor. According to Wartenberg himself, the device was in widespread use in Europe when he lived in Germany. While he did not invent it, he found it "an indispensable part of the outfit for everyday neurologic practice," and recommended its use to his colleagues in the US. The Wartenberg wheel is also used as a sensation sex toy, and is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sex Toy
A sex toy is an object or device that is primarily used to facilitate sexual pleasure, such as a dildo, artificial vagina or vibrator. Many popular sex toys are designed to resemble human genitals, and may be vibrating or non-vibrating. The term ''sex toy'' can also include BDSM apparatus and sex furniture such as sex swings; however, it is not applied to items such as birth control, pornography, or condoms. Alternative terms for ''sex toy'' include adult toy and the dated euphemism marital aid. ''Marital aid'' also has a broader meaning and is applied to drugs and herbs marketed to enhance or prolong sex. Sex toys are most commonly sold at sex shops or online, but they may also be sold in a pharmacy or chemist store, a pornographic store, a head shop, or a department store. Sex toys are available in almost all countries for males and females. Types Erotic electrostimulation Another form of sex toys for both men and women are those for erotic electrostimulation. ...

Medical Equipment
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase. Discovery of what would be considered a medical device by modern standards dates as far back as in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. Study of Archaeology, archeology and Roman medical literature also indicate that many types of medical devices were in widespread use during the time of ancient Rome. In the United States it was not until the Federal Food, Drug, and Cosmetic Act ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spur
A spur is a metal tool designed to be worn in pairs on the heels of riding boots for the purpose of directing a horse or other animal to move forward or laterally while riding. It is usually used to refine the riding aids (commands) and to back up the natural aids (the leg, seat, hands, and voice). The spur is used in many equestrian disciplines. Most equestrian organizations have rules covering spur design and use, as well as penalties for using spurs in any manner that constitutes animal abuse. Etymology This very old word derives from Anglo-Saxon ''spura, spora'', related to ''spornan, spurnan'', to kick, ''spurn''; cf. Medieval High German ''Sporn'', modern German ''Sporn'', Dutch ''spoor''. The generalized sense of "anything that urges on, stimulus" is recorded in English from'' circa'' 1390. Design The parts of a spur include: *The "yoke", "branch", or "heel band", which wraps around the heel of the boot. *The "shank" or "neck", which extends from the back of the yoke ...

Tracing Wheel
A tracing wheel, also known as a pattern wheel, pounce wheel, and dart wheel, is an instrument with multiple teeth on a wheel attached to a handle. The teeth can be either serrated or smooth. It is used to transfer markings from sewing patterns onto fabric with or without the use of tracing paper, and can be used to make slotted perforations. Such markings might include pleats, darts, buttonholes, notches or placement lines for appliques or pockets. The double tracing wheel has two parallel wheels that can be positioned a variable distance apart. This tool can be used to transfer parallel pattern lines onto fabric, such as both the cutting line and the sewing line, where the distance between them is the seam allowance. See also * Pattern notcher * Wartenberg wheel * Pizza cutter * Pouncing Pouncing (Italian ) is an art technique used for transferring an image from one surface to another using a fine powder called pounce. It is similar to tracing, and is useful for crea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Violet Wand
Erotic electrostimulation (abbreviated erotic e-stim and also known as electrosex) is a sexual practice involving the application of electrical stimulation to the nerves of the body, with particular emphasis on the genitals, using a power source (such as a TENS, EMS, violet wands, or made-for-play units) for purposes of sexual stimulation. Electrostimulation has been associated with BDSM activities, and erotic electrostimulation is an evolution of that practice. Safety Electrostimulation, in general, can cause tissue damage or even death if misused. The most common problems arising from electrostimulation tend to be burns from lack of sufficiently wide surface contact, i.e. bad contact, between the electrode and the skin's surface. Even at relatively low current and voltage, there is also risk of interference with normal heart function (potentially including cardiac arrest), and this risk is higher for those who use an artificial pacemaker or similar device or who have hea ...

Tickle Fetishism
Tickle fetishism, also known as knismolagnia, knismophilia, or titillagnia, is a paraphilia where an individual receives sexual pleasure from tickling, being tickled, or watching someone be tickled. Individuals may prefer to be the dominant party, known as a ler (from tick''ler''), or the submissive party, known as a lee (from tick''lee''), or they may enjoy both, known as a switch. Some people may prefer to be tickled in specific areas, typically in an erogenous zone or other particularly sensitive areas of the body.Love B., ''Encyclopedia of Unusual Sex Practices.'' New York: Barricade Books Inc.; 1992. pp. 280–281. In BDSM Restraint, bondage, and sexual humiliation may be aspects of an erotic tickling session, though they are not necessary. A BDSM tickling session can involve submissive partners being tied or restrained in a position that exposes bare parts of the body, particularly those that are sensitive to tickling, such as the feet or armpits. The body being expo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plastic
Plastics are a wide range of synthetic polymers, synthetic or Semisynthesis, semisynthetic materials composed primarily of Polymer, polymers. Their defining characteristic, Plasticity (physics), plasticity, allows them to be Injection moulding, molded, Extrusion, extruded, or Compression molding, pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends ...

Wheel
A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle Bearing (mechanical), bearing. The wheel is one of the key components of the wheel and axle which is one of the Simple machine, six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples can be found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for a wheel to rotate, a Moment (physics), moment must be applied to the wheel about its axis, either by gravity or by the application of another external force or torque.
