Indications for Use

Xinfeng Heating lamp, including CQ-27, CQ-36 and CQ-55A, is an infrared lamp that emits the infrared spectrum to provide topical heating for the purpose of elevating tissue temperature, to temporarily increase local blood circulation, and to temporarily relieve minor muscle and joint pain and stiffness. The lamps may also help to relieve minor pain associated with muscle spasms, minor sprains and strains, and minor muscular back pain.

Device Story

Xinfeng Heating Lamp (models CQ-27, CQ-36, CQ-55A) provides topical infrared heat therapy. Device consists of heating head, swing arm, control box, and pedestal. Operates by emitting infrared spectrum (5-25 microns for CQ-27/36/CQ-55A State I; 2-50 microns for CQ-55A State II) to heat tissue. User positions lamp head 8-12 inches from treatment area; timer controls duration up to 95 minutes. Intended for clinical or home use to relieve minor musculoskeletal pain and stiffness. Healthcare provider or patient monitors treatment distance to maintain skin temperature between 40-45°C (CQ-55A State II requires minimum 10-inch distance). Benefits include temporary pain relief and increased local circulation.

Clinical Evidence

No clinical data. Substantial equivalence is based on bench testing and comparison of technical specifications, materials, and intended use. Safety testing performed according to IEC 60601-1.

Technological Characteristics

Infrared lamp; 110V power; 50/60 Hz; power ≤280W. Components: heating head, swing arm, control box, pedestal. Emission spectrum: 5-25 microns (standard) or 2-50 microns (CQ-55A State II). Timer: up to 95 minutes. Safety: 2 fuses, 5 casters. Tested to IEC 60601-1. Heating plate replacement required after 1,000 hours.

Indications for Use

Indicated for patients requiring topical heating to elevate tissue temperature, increase local blood circulation, and temporarily relieve minor muscle/joint pain, stiffness, muscle spasms, minor sprains, strains, and minor muscular back pain.

Regulatory Classification

Identification

An infrared lamp is a device intended for medical purposes that emits energy at infrared frequencies (approximately 700 nanometers to 50,000 nanometers) to provide topical heating.

Special Controls

*Classification.* Class II (special controls). The device, when it is an infrared therapeutic heating lamp, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 890.9.

# Description of the Xinfeng Heating Lamps:

Xinfeng Heating Lamp, including 3 different models CQ-27, CQ-36 and CQ-55A, consists of heating head, swing arm, control box and pedestal with extension. It is used to provide topical heating to the body and is specially engineered using a plate. Model CQ-27 and CQ-36 have only one operating mode, while model CQ-55A has two operating modes. Emission spectrum ranges from 5 to 25 microns for models CQ-27, CQ-36 and state I of CQ-55A. Model CQ-55A also includes an additional operating state (State II) having an emission range of 2 to 50 microns. The emission heating plate shall be replaced after 1,000 hours of usage.

#### Indications for use

Xinfeng Heating Lamp, including 3 different models CQ-27, CQ-36 and CQ-55A, is an infrared lamp that emits the infrared spectrum to provide topical heating for the purpose of elevating tissue temperature, to temporarily increase local blood circulation, and to temporarily relieve minor muscle and joint pain and stiffness. The lamps may also help to relieve minor pain associated with muscle spasms, minor sprains and strains, and minor muscular back pain.

# Substantial Equivalence Information

Xinfeng CQ-27, CQ-36 and CQ-55A Heating Lamps are generally equivalent to CQ-27 Heat Lamp (K003538) manufactured by Lhasa Medical, Inc. on label and labeling, materials used, specifications and intended use. All the technical data are tested according to GB 9706.1-1995 which is identical to IEC 60601-1

The equivalence information is focused on intended use, materials and specifications. The Xinfeng Heating lamps use 110V voltage, 5 casters and 2 fuses. The use age is 1000 hours and the skin temperature is at 40~45°C in a treatment distance from heating unit to treatment surface 8" to12" for models CQ-27, CQ-36 and state I of CQ-55A, but for state II operating mode of CQ-55A it is 10" to12".
