Surgical Lubricant
Surgical lubricants, or medical lubricants, are substances used by health care providers to provide lubrication and lessen discomfort to the patient during certain medical and surgical procedures such as vaginal or rectal examinations. Some example of surgical compatible lubricants are: * Surgilube is a surgical lubricant made of natural water-soluble gums that also contains the antiseptic chlorhexidine gluconate. * K-Y Jelly was initially used as a surgical lubricant before it gained popularity as a personal lubricant. * Lignocaine gel containing the local anaesthetic lignocaine is a prime example of a non-irritating substances used as surgical lubricant * Medicinal castor oil was the original vegetable-based surgical lubricant. * Indications for medical lubricants: Sjögren syndrome, specifically for treating vaginal dryness, dyspareunia (painful sexual intercourse) and vulvodynia Vulvodynia is a chronic pain condition that affects the vulvar area and occurs without an ...

Lubrication
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished. Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. By repelling water and other substances, it also reduces corrosion. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure. Lubrication mechanisms Fluid-lubricated systems As the load incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vagina
In mammals and other animals, the vagina (: vaginas or vaginae) is the elastic, muscular sex organ, reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The #Vaginal opening and hymen, vaginal introitus is normally partly covered by a thin layer of mucous membrane, mucosal tissue called the hymen. The vagina allows for Copulation (zoology), copulation and birth. It also channels Menstruation (mammal), menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, en ...

Rectal Examination
Digital rectal examination (DRE), also known as a prostate exam (), is an internal examination of the rectum performed by a healthcare provider. Prior to a 2018 report from the United States Preventive Services Task Force, a digital exam was a common component of annual medical examination for older men, as it was thought to be a reliable screening test for prostate cancer. Usage This examination may be used: * for the diagnosis of prostatic disorders, benign prostatic hyperplasia and the four types of prostatitis. Chronic prostatitis/chronic pelvic pain syndrome, chronic bacterial prostatitis, acute (sudden) bacterial prostatitis, and asymptomatic inflammatory prostatitis. The DRE has a 50% specificity for benign prostatic hyperplasia. Vigorous examination of the prostate in suspected acute prostatitis can lead to seeding of septic emboli and should never be done. Its utility as a screening method for prostate cancer however is not supported by the evidence; * for the eva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chlorhexidine Gluconate
Chlorhexidine is a disinfectant and antiseptic which is used for skin disinfection before surgery and to disinfect surgical instruments. It is also used for cleaning wounds, preventing dental plaque, treating yeast infections of the mouth, and to keep urinary catheters from blocking. It is used as a liquid or a powder. It is commonly used in salt form, either the gluconate or the acetate. Side effects may include skin irritation, tooth discoloration, and allergic reactions, although, apart from discoloration, the risk appears to be the same as that for povidone-iodine. Chlorhexidine rinse is also known to have a bitter metallic aftertaste. Rinsing with water is not recommended as it is known to increase the bitterness. It may cause eye problems if direct contact occurs. Use in pregnancy appears to be safe. Chlorhexidine may come mixed in alcohol, water, or surfactant solution. It is effective against a range of microorganisms, but does not inactivate spores. Chlorhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Lubricant
Personal lubricants (colloquially termed lube) are specialized lubricants used during sexual acts, such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus or other body parts, or applied to sex toys to reduce friction or to ease penetration. As of 2015, the personal lubricant market was estimated to be worth at least $400 million. Surgical or medical lubricants or gels, which are similar to personal lubricants but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter. The primary difference between personal lubricants and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent. Types By composition Water-based Water-based personal lubricants are water- soluble and are the most widely used personal lubricants. The earliest water-based lubricants were cellulose ether or gly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignocaine
Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type. It is also used to treat ventricular tachycardia and ventricular fibrillation. When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours. Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area. It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding. If injected intravenously, it may cause cerebral effects such as confusion, changes in vision, numbness, tingling, and vomiting. It can cause hypotension, low blood pressure and an irregular heart rate. There are concerns that injecting it into a joint can cause problems with the cartilage. It appears to be generally safe for use in pregnancy. A lower dose may be required in those with liver pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castor Oil
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant ''Ricinus communis''. The seeds are 40 to 60 percent oil. It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is and its density is 0.961 g/cm3. It includes a mixture of triglycerides in which about 90 percent of fatty acids are Ricinoleic acid, ricinoleates. Oleic acid and linoleic acid are the other significant components. Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes, nylon, and perfumes. Etymology The name probably comes from a confusion between the ''Ricinus'' plant that produces it and another plant, the ''Vitex agnus-castus''. An alternative etymology, though, suggests that it was used as a replace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vaginal Dryness
Vaginal lubrication is a naturally produced fluid that lubricates the vagina. Vaginal lubrication production increases significantly during sexual arousal in anticipation of sexual intercourse. Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial lubricants are used to augment it. Without sufficient lubrication, sexual intercourse can be painful. The vaginal lining has no glands, and therefore the vagina must rely on other methods of lubrication. Plasma from the vaginal walls due to vascular engorgement is considered to be the chief lubrication source, and the Bartholin's glands, located slightly below and to the left and right of the introitus (vaginal opening), also secrete mucus to augment vaginal wall secretions. Near ovulation, cervical mucus provides additional lubrication. Mechanism Composition Vaginal lubrication fluid is a plasma transudate which diffuses across the vaginal wall. Composition varies with the length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyspareunia
Dyspareunia ( ) is painful sexual intercourse due to somatic or psychological causes. The term ''dyspareunia'' covers both female dyspareunia and male dyspareunia, but many discussions that use the term without further specification concern the female type, which is more common than the male type. In females, the pain can primarily be on the external surface of the genitalia, or deeper in the pelvis upon deep pressure against the cervix. Medically, dyspareunia is a pelvic floor dysfunction and is frequently underdiagnosed. It can affect a small portion of the vulva or vagina or be felt all over the surface. Understanding the duration, location, and nature of the pain is important in identifying the causes of the pain. Numerous physical, psychological, and social or relationship causes can contribute to pain during sexual encounters. Commonly, multiple underlying causes contribute to the pain. The pain can be acquired or Congenital disorder, congenital. Symptoms of dyspareunia may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
