List of instruments used in endocrinology

none


none

Endocrinology is a branch of internal medicine dealing with hormones, the chemical messengers released internally to regulate the body's physiologic functions. Endocrinologists diagnose and manage diseases of endocrine glands, including hypothalamus, pituitary, thyroid, parathyroid, pancreatic islets, adrenals, testes, and ovaries. Some of the most common conditions treated are diabetes mellitus, diseases of the thyroid gland, metabolic bone disorders, pituitary disorders, and disorders of the reproductive system and infertility; in children, typical conditions are growth deficiency, delay of puberty, and a variety of genetic disorders. In endocrinology, diagnosis is heavily relied on laboratory tests, as it is important to find out diseases before they actually become clinically evident; still, medical history and physical examination remain indispensable. As a branch of internal medicine, practice of endocrinology makes use of common medical instruments, used by all or most clinical specialties, like the stethoscope or the sphygmomanometer. The following list does not include these, but only instruments that have relatively specific uses central to endocrinology (but not necessarily limited to it). They are either utilized by the physician (generally the endocrinologist themselves, or potentially by a different specialist, like a radiologist) for diagnosis or treatment; or prescribed for patient use.

**General**
Ultrasound systemA console, or a portable system, which includes a monitor and a transducer, and utilizes ultrasound to image body tissues.last1=Soffermanfirst1=RAeditor1-last=Soffermaneditor1-first=RAeditor2-last=Ahujaeditor2-first=Atitle=Ultrasound of the Thyroid and Parathyroid Glandsdate=2012publisher=Springer New Yorkisbn=9781461409748pages=21–38chapter-url=https://link.springer.com/chapter/10.1007/978-1-4614-0974-8_3access-date=22 February 2024chapter=Practical Concepts of Ultrasounddoi=10.1007/978-1-4614-0974-8_3 }} or therapeutic ethanol injection to these organs. To evaluate testes (scrotal ultrasound) and ovaries (pelvic ultrasound).[[File:AlokaPhoto2006a.jpg150px]]
**Diabetes**
Continuous glucose monitorConsists of a sensor electrode (implanted or disposable) that measures glucose concentration in the interstitial fluid, and a receiver device where the measurements are sent through by a transmitter to be displayed.To automatically measure glucose at regular intervals (e.g. every 5–15 minutes). Measurements can be displayed to the patient continuously, or after scanning the device. An alarm may sound to notify of measured or predicted hyper- or hypoglycemia.[[File:BGM twopart.JPG150px]]
Glucose meterA portable electronic device that takes single-use strips, where a drop of blood is placed. Allows self-monitoring by the patient.To measure blood glucose[[File:Blood Glucose Testing.JPG150px]]
Insulin penA portable drug-delivery device, comprising an insulin container (prefilled for disposable pens, or refillable with cartridges); a dialing system to select the dose (in increments of 0.5 or 1 Unit); and a button which delivers the drug when pressed; disposable needles are attached prior to each use.To administrate insulin under the skin. Smart insulin pens have been developed that wirelessly connect to mobile apps, to log doses and variously facilitate therapy.[[File:Inzulínová pera.jpg150px]]
Insulin pumpA small, portable pump, which delivers insulin from a container, via a plastic tubule and a cannula, under the skin.To continuously infuse fast-acting insulin that covers the basal insulin needs of the body, and also bolus doses as needed for meals or high glucose values. Pumps can be augmented with continuous glucose monitors, to better control insulin administration.[[File:Insulin pump with infusion set.jpg150px]]
Lancing deviceA portable instrument that takes single-use needles or lancets. It contains a spring, which is cocked and released by buttons. Once loaded, the device is held against a fingertip, and upon release the spring drives the lancet to prick the skin rapidly, and thereby less painfully. It also includes a controlling system to alter the penetration depth.last1=Walkerfirst1=RAtitle=The Diabetes Handbookdate=2020publisher=Dorling Kindersley Limitedisbn=9780241504062page=32url=https://books.google.com/books?id=oXoBEAAAQBAJaccess-date=26 February 2024}}[[File:Testing Blood Sugar Levels.jpg150px]]
**Thyroid gland disorders**
Hertel exophthalmometerA system of mirrors or prisms that projects a lateral view of the eye against a ruler that measures the distance from the lateral canthus to the anterior surface of the corneaTo evaluate the prominence of the eye, which increases in hyperthyroidism[[File:Exophthalmometer.jpg150px]]
Luedde exophthalmometerA transparent ruler, held against the lateral rim of the orbitTo evaluate the prominence of the eye
**Disorders of male sex hormones**
Nocturnal penile tumescence and rigidity deviceA wearable device including loop transducers that are wrapped around the penis, which connects to a microcomputer.To evaluate nocturnal erections end male sexual potency
Prader orchidometerA string of testicle-shaped beads of increasing sizeTo measure, by comparison, the size of testicles[[File:Orchidometr.png150px]]
Seager orchidometerA calliperTo measure the long axis of the testicle
