Heel lifts or height insoles are a wedge-shaped shoe insert which fits in the heel portion of a shoe, with the purpose of adding elevation under one or both feet for therapeutic purposes. Heel lifts are commonly used as therapy for leg-length differences leading to knee, hip and back pain, to reduce stress on the Achilles' tendon during healing, and for various rehab uses. Heel lifts are distinct from heel pads. The intent of a heel lift is not to absorb shock or spread pressure on the heel, but to raise one foot in order to shift balance and gait. As such, heel lifts should be firm and not compressible, in order to add a constant amount of height without causing the heel to rub vertically in the shoe. Heel lifts can cause various side effects similar to wearing high-heeled shoes, and their use should be prescribed by health care professionals.

Heel pads are especially designed for the treatment of heel pain associated with a bony spur under the heel bone. It has a special cushioning gel in the middle, which takes the stress off the underside of the heel and help to relieve the symptoms of Plantar Fasciitis.

Heel Pain Reducer is a proprioceptive neuromuscular facilitation exercise device including a drive motor, gear mechanism , a control connected with the motor for operating the motor in either direction and a rotating member connected with the gear mechanism and adapted to be coupled to a body member of a user for moving the body member in the desired direction. The movable member moves in increments and is lockable at desired positions for holding the body member against a force tending to return it to normal position or a force in the opposite direction. One exercise device rotates the upper torso relative to the spine. Another of the exercise devices rotates the upper legs of a user relative to the hip joints and lower legs relative to the knees. A further device operates the arms forward and backward relative to the shoulder joint and includes parallel vertical shafts movable together and apart to adjust for different distances between the shoulder joints of a user.

Helical CT scan is a special type of CT scan technique that involves continuous movement of the patient through the scanner with the ability to scan faster and with higher definition of internal structures. Helical CT scanning can permit greater visualization of blood vessels and internal tissues, such as those within the chest cavity. This form of scanner may be particularly helpful in the rapid evaluation of severe trauma injuries, such as those sustained in automobile accidents. A helical CT scan is also referred to as spiral CT scans.

Helical Stone Extractors are used for stone manipulation and removal in the urinary tract.

Helicobacter pylori IgA ELISA kit is used for the measurement of human IgG class antibodies to helicobacter pylori in serum and EDTA or heparin plasma.

Hematology analyzer is a device used to measure WBC, RBC, Hgb, Hct, MVC, Plt, L%, and L#. Usually it is based on the principle that different blood cells have different densities. Therefore, when blood is spun in a microhematocrit tube, the cells separate into three distinct layers: the red blood cells (which have the greatest density), the buffy coat and the plasma. A molded cylindrical float inserted into a precision-bore capillary tube expands the buffy coat. The specific gravity of the float is approximately midway between that of the plasma and the red cells, causing the buffy coat to expand along the length of the float. Expanded layers of packed white cells and platelets resolve between the float and the inner wall of the tube.
