BED HAVING PATIENT WARMING APPARATUS
FIELD OF THE INVENTION
The present invention relates to a hospital bed and, more particularly, to a hospital bed having the capabilitiy to supply temperature-controlled air to a patient.
BACKGROUND OF THE INVENTION
There are certain circumstances in which it is desirable to supply temperature-controlled air to a hospital patient. For example, where a patient has had surgery, the after effects of the anesthesia may include chills. Therefore, in a recovery room, it is common to take certain steps to attempt to warm the patient, for example by placing a pre-warmed blanket over the patient. In other situations, it may be desirable to supply hot or cold air to a particular localized area such as the feet, ankles or knees of a patient.
A number of devices have previously been developed to supply temperature-controlled air to a patient. While these arrangements have generally been satisfactory for their intended purposes, they have not been satisfactory in all respects. Accordingly, one object of the invention is to provide a hospital bed designed to provide temperature-controlled air to a patient in an efficient and reliable manner.
