![]() ![]() Symptoms and objective findings, including measurements which establish the severity of the condition. ![]() The determination by the physician of the medical necessity of a pneumatic compression device must include: Pneumatic compression devices are covered only when prescribed by a physician and when they are used with appropriate physician oversight, i.e., physician evaluation of the patient's condition to determine medical necessity of the device, assuring suitable instruction in the operation of the machine, a treatment plan defining the pressure to be used and the frequency and duration of use, and ongoing monitoring of use and response to treatment. The trial of conservative therapy must include a compression bandage system or compression garment, appropriate dressings for the wound, exercise, and elevation of the limb. Pneumatic compression devices are covered in the home setting for the treatment of CVI of the lower extremities only if the patient has one or more venous stasis ulcer(s) which have failed to heal after a 6 month trial of conservative therapy directed by the treating physician. Signs of CVI include hyperpigmentation, stasis dermatitis, chronic edema, and venous ulcers. The garment may be prefabricated or custom-fabricated but must provide adequate graduated compression.Ĭhronic Venous Insufficiency With Venous Stasis UlcersĬhronic venous insufficiency (CVI) of the lower extremities is a condition caused by abnormalities of the venous wall and valves, leading to obstruction or reflux of blood flow in the veins. The trial of conservative therapy must include use of an appropriate compression bandage system or compression garment, exercise, and elevation of the limb. Pneumatic compression devices are covered in the home setting for the treatment of lymphedema if the patient has undergone a four-week trial of conservative therapy and the treating physician determines that there has been no significant improvement or if significant symptoms remain after the trial. ![]() Secondary lymphedema, which is much more common, results from the destruction of or damage to formerly functioning lymphatic channels, such as surgical removal of lymph nodes or post radiation fibrosis, among other causes. Primary lymphedema is a relatively uncommon, chronic condition which may be due to such causes as Milroy's Disease or congenital anomalies. Lymphedema is divided into two broad classes according to etiology. The accumulation of lymph fluid results from impairment to the normal clearing function of the lymphatic system and/or from an excessive production of lymph. Lymphedema is the swelling of subcutaneous tissues due to the accumulation of excessive lymph fluid. By eliminating the risk of human error that can occur during the manual handling of samples, the device ensures that results are consistent, reducing the need for repeat experiments.Pneumatic devices are covered for the treatment of lymphedema or for the treatment of chronic venous insufficiency with venous stasis ulcers. The automation of the sequential injection method enables precise control over reaction conditions, ensuring that experiments are reproducible and reliable. The device’s rapid processing times and ability to inject multiple samples in a sequence make it an ideal tool for high-throughput applications. This instrument enables high throughput analysis by automating sample injection, reducing the time and effort required for manual sample handling. With that upgrade, get rid of a dozen pneumatic lines and holders, simplifying your experiment and making space on your lab table. The device’s modular design also enables researchers to customize the device to suit their specific experimental needs, without sacrificing space. The distribution valve features a compact and space-saving design, making it ideal for laboratories with limited bench space. You won’t need a reservoir holder anymore. On the same device, plug 50ml, 15m, and 1,5ml reservoirs at the same time. Our device is designed to be user-friendly, with an intuitive reservoir quick connection and a simple interface that makes it easy to set up and operate. ![]()
