Catheter | In medicine, a catheter is a thin tube made from medical grade materials serving a broad range of functions. Catheters are MedicalDevices that can be inserted in the body to treat diseases or perform a surgical procedure. Catheters are manufactured for specific applications, such as cardiovascular, urological, gastrointestinal, neurovascular and ophthalmic procedures. The process of inserting a catheter is Catheterization. Catheters can be inserted into a BodyCavity, duct, or vessel, Brain, Skin or adipose tissue. Functionally, they allow drainage, administration of Fluids or Gases, access by surgical instruments, and also perform a wide variety of other tasks depending on the type of catheter. Special types of catheters, also called probes, are used in preclinical or clinical research for sampling of lipophilic and hydrophilic compounds, protein-bound and unbound drugs, neurotransmitters, peptides and Proteins, Antibodies, nanoparticles and nanocarriers, Enzymes and vesicles.[from Wikipedia] | | | ChestSeal | A MedicalDevice designed to seal a wound in the Chest, preventing, or ameliorating, a Pneumothorax. | | | Needle | A needle is a MedicalDevice intended for Inserting or Removing a Fluid Inside a patient. | | | PulseOximeter | Pulse oximetry is a noninvasive method for monitoring a person's Blood Oxygen saturation. Peripheral oxygen saturation (SpO2) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of the more accurate (and invasive) reading of arterial oxygen saturation (SaO2) from arterial blood gas analysis. The most common approach is transmissive pulse oximetry. In this approach, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or an infant's foot. The device passes two wavelengths of light through the BodyPart to a photodetector. It measures the changing absorbance at each of the wavelengths, allowing it to determine the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, Bone, Muscle, FatTissue, and, in most cases, nail polish. [from Wikipedia] | | | SalineLock | A saline lock is a valve that is intended to be connected to an IVLine. It is pre-filled with a SalineSolution since that has a neutral effect (it is isotonic) on the Blood. |
