The application of ice after surgery or injury to reduce swelling and pain is a well established treatment with well know indications and contraindications.
The device consists of a tank containing ice and water, a water pump to circulate cold water, a console containing a means to control and indicate temperature and a pad through which the cold water circulates. The purnp, contained in a waterproof case, is submerged in the ice water bath and connected to the console via insulated tubing through which the chilled water flows to and from the pad. The console is located along this tubing about halfway between the pad and the water bath for easy access by the patient. Leakage current for the device shall not exceed 100uA.
This document describes an ice therapy device. The provided text is a summary of safety and effectiveness, but it does not contain any information about acceptance criteria or a study proving the device meets those criteria, as typically understood in the context of AI/ML devices or diagnostic tools.
The document discusses:
- The general concept of cold therapy after surgery/injury.
- The device's components (tank, pump, console, pad).
- A safety specification: "Leakage current for the device shall not exceed 100uA." This is a single electrical safety standard, not a set of performance acceptance criteria.
- References to existing literature on the benefits of cold therapy, implying its well-established nature, rather than a specific study conducted for this device's performance.
- A comparison to other similar devices on the market, noting they are "more convenient and safer means to apply ice."
Therefore, I cannot fulfill the request as the essential information is missing from the provided text. To answer your questions, I would need a description of:
- Specific performance metrics (e.g., cooling rate, temperature accuracy, duration of cooling, comfort metrics, etc.)
- Target values or ranges for these metrics (acceptance criteria).
- Details of a study that measured these metrics for the device.
Without this information, I cannot complete the table or answer the specific questions about sample sizes, ground truth, expert involvement, or AI-related aspects, as these pertain to a different type of device evaluation than what is presented here.
§ 890.5720 Water circulating hot or cold pack.
(a)
