Gag (medical Device)
300px, Jennings gag In the context of surgery or dental surgery, a gag is a device used to hold the patient's mouth open when working in the oral cavity, or to force the mouth open when it cannot open naturally because of forward dislocation of the jaw joint's intraarticular cartilage pad. Applications for medical gags include oral surgery and airway management. Gag designs, like other medical instrument designs, are often named after their inventors. Common examples of medical gags include the Jennings, Whitehead, and Hallam gags. Types *Whitehead gag: invented in 1877 by Walter Whitehead (1840-1913), a surgeon in Manchester, England, consists of two hinged metal frames that wrap around the front of the patient's head and which have sections bent to fit between the front teeth. When spread apart, the frames separate the jaws, holding the mouth open. The desired degree of separation is set and maintained by a ratchet mechanism on each side of the frame. *Jennings gag: they are ver ...

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...

Mouth Prop
A mouth prop (also bite block) is a wedge-shaped implement used in dentistry for dentists working with children and other patients who have difficulty keeping their mouths open wide and steady during a procedure, or during procedures where the patient is sedated. It has a rubber-like texture and is typically made from thermoplastic vulcanizate (TPV) material. They come in several different sizes, from pediatric to adult, and are typically ridged as to use the back teeth to hold them in place.

Medical Device
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 c. 7000 BC in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. Study of 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 wasn't until the Federal Food, Drug, and Cosmetic Act (F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gag (BDSM)
A gag is a device used in bondage (sexual), sexual bondage and BDSM sexual roleplay, roleplay. Gags are usually associated with roleplays involving bondage, but that is not necessarily the case. The person who wears the gag is regarded as the bottom (BDSM), submissive partner, while the other is regarded as the top (BDSM), dominant one. People may wear gags for a variety of reasons. Some people derive erotic pleasure from a gag, either in a dominance and submission, submissive or dominant role. When combined with other physical restraints, the wearing of a gag can increase the wearer's sense of helplessness and anxiety level within a BDSM scene by rendering them unable to speak during sexual activity, which some people enjoy. For some people, gags have connotations of punishment and control, and thus can be used as a form of humiliation (BDSM), humiliation. To some, wearing a gag without restraints is still an act of humiliation, as is an open mouth gag. Some sexual fetishism, f ...

Bondage (BDSM)
Bondage in the BDSM subculture, is the practice of consensually tying, binding, or restraining a partner for erotic, aesthetic, or somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope, cuffs, bondage tape, or self-adhering bandage. Bondage itself does not necessarily imply sadomasochism. Bondage may be used as an end in itself, as in the case of rope bondage and breast bondage. It may also be used as a part of sex or in conjunction with other BDSM activities. The letter "B" in the acronym "BDSM" comes from the word "bondage". Sexuality and erotica are an important aspect in bondage, but are often not the end in itself. Aesthetics also plays an important role in bondage. A common reason for the active partner to tie up their partner is so both may gain pleasure from the restrained partner's submission and the feeling of the temporary transfer of control and power. For sadomasochistic people, bondage is often u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Fetishism
Sexual fetishism or erotic fetishism is a sexual fixation on a nonliving object or nongenital body part. The object of interest is called the fetish; the person who has ''a fetish'' for that object is a fetishist. A sexual fetish may be regarded as a non-pathological aid to sexual excitement, or as a mental disorder if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. Sexual arousal from a particular body part can be further classified as partialism. While medical definitions restrict the term ''sexual fetishism'' to objects or body parts, ''fetish'' can, in common discourse, also refer to sexual interest in specific activities. Definitions In common parlance, the word ''fetish'' is used to refer to any sexually arousing stimuli, not all of which meet the medical criteria for fetishism. This broader usage of ''fetish'' covers parts or features of the body (including obesity and body modifications), object ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the opposite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Walter Whitehead
Walter Whitehead, , (12 October 1840 – 19 August 1913) was a surgeon at various hospitals in Manchester, England, and held the chair of Clinical Surgery at the Victoria University of Manchester. He was president of the British Medical Association in 1902. He once claimed that knowledge of anatomy was an impediment to being a good surgeon but was himself a bold, innovative practitioner of international repute. His procedure for excision of the tongue using scissors and his formulation of a related ointment became a standard treatment, as did a procedure he developed for the treatment of haemorrhoids. Whitehead was born to a family with a long-standing interest in textile manufacture in Bury, Lancashire. His interest in medicine was piqued when he attended lectures intended to improve his knowledge of the chemical processes of bleaching cloth. He enrolled at the Manchester Royal School of Medicine without telling his parents and thus embarked on his medical career. He ...

Airway Management
Airway management includes a set of maneuvers and medical procedures performed to prevent and relieve airway obstruction. This ensures an open pathway for gas exchange between a patient's lungs and the atmosphere. This is accomplished by either clearing a previously obstructed airway; or by preventing airway obstruction in cases such as anaphylaxis, the obtunded patient, or medical sedation. Airway obstruction can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents ( aspiration). Airway management is commonly divided into two categories: basic and advanced. Basic techniques are generally non-invasive and do not require specialized medical equipment or advanced training. These include head and neck maneuvers to optimize ventilation, abdominal thrusts, and back blows. Advanced techniques require specialized medical training and equipment, and are further categorized anatomically into supraglottic device ...
