Classification of Medical Instruments: Medical instruments are essential tools used in diagnosing, treating, and monitoring patients. Proper classification is critical for healthcare professionals to understand their application, maintenance, and sterilization. 1. Diagnostic Instruments These instruments are used to identify diseases or medical conditions. A. Examples: - Stethoscope: Used to listen to internal sounds, such as heartbeats and lung sounds. - Otoscope: Examines the ear canal and tympanic membrane. Figure 1: otoscope - Sphygmomanometer: Measures blood pressure. - Thermometer: Measures body temperature. - Electrocardiograph (ECG): Records the electrical activity of the heart. B. Ophthalmic Instruments These instruments are used specifically for diagnosing eye conditions. Such as: - Ophthalmoscope: Used to examine the interior of the eye, especially the retina. - Slit lamp: Provides a magnified view of the eye to assess structures like the cornea, and lens. C. Imaging Instruments Imaging devices provide visual representations of the inside of the body Examples: a. X-ray machines: Produce images of bones and internal organs. b. Ultrasound machines: Use sound waves to create images of soft tissues c. CT (Computed Tomography) scanners: Provide detailed cross- sectional images of the body. d. MRI (Magnetic Resonance Imaging): Uses magnetic fields to produce detailed images of soft tissues, such as the brain. 2. Surgical Instruments These tools are used during surgery for cutting, dissecting, grasping, suturing, and other procedures. Such as: a. Cutting and Dissecting Instruments i. Scalpel: For making incisions. ii. Scissors: For cutting tissues. b. Grasping and Holding Instruments: i. Forceps: For holding tissues or objects. ii. Clamps: To control bleeding by clamping blood vessels. c. Retractors: Used to hold back tissue or organs. d. Suturing Instruments: Needle holders used for holding needles during suturing.

Nebulizers: Convert liquid medication into a mist for inhalation, often used for asthma. b. Dialysis machines: Used for renal failure treatment to filter and purify the blood. c. Pacemakers: Regulate the heart rate using electrical impulses. 4. Monitoring Instruments These instruments continuously or periodically measure a patient’s vital signs. Examples: a. Pulse oximeter: Measures oxygen saturation levels in the blood. b. Glucose monitors: Measure blood sugar levels, primarily used by diabetic patients. c. Fetal monitors: Monitor the heart rate of a fetus during. 5. Laboratory Instruments Used for analyzing samples (blood, urine, tissues) to detect diseases or other medical conditions. These instruments are generally found in clinical labs or hospitals. Examples: a. Centrifuge: Separates fluids, such as blood, into different components (e.g., plasma, red cells). b. Microscope: For viewing cells and tissues at a microscopic level.  6. General Purpose Instruments These are instruments used across different medical fields and can perform a variety of functions. Examples: a. Syringes and needles: For injecting medications or drawing blood. b. Catheters: Inserted into body cavities to drain fluids or administer drugs. c. Suction devices: Used to clear airways or remove fluids during surgery.
