Description

1. 1. Technical Fields The present invention generally relates to devices and methods for maintaining a patient's body temperature during a surgical procedure, more specifically helping to maintain a patient's core body temperature within the normal temperature range, and further, a remote caregiver. Concerning surgical insulating caps incorporating graphic display panels to provide an information interface.

2. 2. Description of Related Techniques The majority of anesthetized patients experience some degree of hypothermia. The decrease in body temperature is variable, but is exacerbated by procedures that involve exposure to larger, longer-term surgery. Relative hypothermia can have serious and adverse effects on the patient, especially during the perioperative and postoperative periods. Hypothermia-related complications include myocardial ischemia, hypertension, tachycardia, and infections that lead to unexpected mortality and morbidity. Most of the patient's heat capacity is lost from the uncovered head, so the medical industry is addressing the problem by developing means to keep the patient at normal temperature.

The present invention provides a surgical insulating cap designed to mimic the patient's head and ears and maintain its position during surgery, with continuous and accurate standard vital body sign parameters such as body temperature. Other bios such as temperature heart rate rhythm, heart rate, respiratory activity, SpO2 that can be provided as well as sufficient to detect malignant hyperthermia or hypothermia, as well as other adverse perioperative and postoperative conditions. Teaching in combination with an interface for displaying the output of a biometric sensor, which can also include sensors for metric data.

It is an object of the present invention to provide a flexible, disposable surgical cap worn by a patient during a surgical procedure. It is an object of the present invention to reduce the risk that patients, especially older patients at higher risk, develop other conditions associated with hypertension, tachycardia, and surgical hypothermia. The purpose of the cap is to be composed of an insulating material that is both elastic and flexible in order to provide a means for the cap to trace the contour of the head.

The surgical cap is intended to be constructed to minimize exposure to fibrous materials and thus remove habitats for bacterial growth.

More specifically, the cap is a commercially available synthetic material (hereinafter referred to as "phase change material") having a ceramic fiber material and a fiber containing a plurality of microencapsulated paraffinic hydrocarbons, and 65% olefin and Includes synthetic microfibers with a composition close to 35% polyester. The cap extends over a larger portion of the patient's forehead, above the patient's ears, and behind the head, reaching the upper part of the lumbar spine. According to one aspect of the invention, the surveillance sensor may be in contact with the patient's head and integrated directly into the cap to facilitate acquisition and display of standard vital sign parameters. According to yet another aspect of the invention, the cap can communicate with various other surveillance sensors placed around the patient for acquisition of standard body sign parameters. In any aspect, any number of standard body sign parameters such as ECG, heart rate, respiration, oxygen saturation (SpO2), temperature, etc. can be obtained. In addition, advanced measurements can be additionally integrated simply by including the appropriate biometric sensors and analyzers.

The surgical cap is intended to include a caregiver interface in the form of a display screen positioned in front of the cap aligned to the patient's forehead. The present invention provides use in an environment beyond the operating room. Due to the location and behavior of such interface display screens, doctors, nurses, EMTs, etc. have chosen in a way that not only moves with the patient, but also eliminates the need for caregivers to distract attention from patient care activities. You can easily access the information output from the vital body sign sensor.

It is an object of the present invention to provide a surgical insulating cap that helps maintain a patient's core body temperature within the normal temperature range and also incorporates an information display for communicating with biometric sensor functions.
