A medical apparatus and method for medical patients that suffer from Sleep Apnea. A breathing mask that fits comfortably over a nose area. Because a mask is shaped to a face, it is less bulky and cumbersome over the nose area. Inside a shell of a mask, towards a patients' face, is a silicone wax lining that is on the inner rim of a shell and parameters to enclose a nose as a seal. A silicone wax substance is novel to a device because of its ability to retain a form it has been molded into. A silicone wax lining around a nose allows a patient to form and mold a substance against a face and provide an air-tight seal. A single strap is used to fasten and secure a mask to a face. Tabs or buckle can be used to fasten a strap.

A system for measuring and converting to an observer intelligible form an internal physiological parameter of a medical patient. The invention allows transcutaneous telemetry of the measured information intracranial pressure via a system which includes a patient implanted sensor module and a processing and display module which is external of the patient and optically coupled to the sensor module via an external coupling module. A sensor within the implanted module transduces the measured information and a near infrared (NIR) emitter transmits this telemetry information when interrogated by the complementary external coupling module. Alternately, a set of tuned inductor-crystal circuits versus inductor-crystal comprised in part of a cylindrical crystal oscillator whose resonant frequency is sensed by a dipper circuit arrangement is provided. Power for the sensor module is derived inductively through rectification of a transcutaneously-applied high-frequency alternating electromagnetic field which is generated by a power source within the external coupling module, in concept much like a conventional electrical transformer. A computer within the processing and display module calculates the parameter value from the telemetry signal and represents this data either in numerical, graphical, or analog format.

A medical line securement device allows for inspection, repositioning, replacement and servicing of a medical line without removing an adhesive patch attached to the neonate's skin, thereby saving the thin and fragile skin of the neonate. The securement device provides a releasable attachment between the adhesive anchor patch, which is attached to the neonate, and a coupler of the securement device, which is attached to the medical line. The patch has a base, a fastening element, and an adhesive layer that attaches to the skin of a medical patient. The coupler attaches to the medical line. By this configuration, the patch and coupler cooperate to retain and releasably secure a medical line to the patient. The device is particularly adapted for use in connection with neonates and provides a small securement surface to fit onto the small body locations of a neonate. The securement device consequently can be used to couple different types of catheters or tubes at different locations on the neonates body.

In some embodiments of the invention, an access device can be provided. Advantageously, the access device can enhance the detection of the device's access into a desired body space. For example, the access device may have portions with enhanced visibility to a naked human eye, or an imaging device such as a medical imaging device. Where an imaging device is used, the imaging device can image the access device in a space that usually would not be visible to an operator, such as within a medical patient's body. Where the access device is directly viewed by a human eye, the access device can provide some form of feedback that allows an operator to more quickly discern if the access device has entered a desired space. For example, if the access device is to enter a blood-filled body space, the access device can allow blood to flow up and into the device, and the device can make the blood's presence more immediately apparent. One method of making the blood's (or another fluid) presence more immediately apparent is using a portion with contrasting optical properties.
