A mask system for use between a patient and a device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

A headgear for use with a mask includes a first strap being configured to engage a back of a patient's head and extend on either side of the patient's parietal bone behind the patient's ears and assume, in use, a substantially circular or oval shape. At least a portion of the first strap is substantially inextensible. The headgear also includes at least one second strap configured to removably connect the first strap to the mask. The second strap may be more extensible than the first strap. At least a portion of the first strap is self-supporting such that the headgear maintains a three dimensional shape when not in use. The substantially inextensible portion of the first strap is constructed to resiliently return to a predetermined shape when not in use. The arcuate region includes a first portion that may be arranged to align substantially parallel with a top of the patient's head and a second portion being arranged to align substantially to a rear surface of the patient's head.

Disclosed is a travel pillow for providing the head and neck alignment of a human user resting against a seat back. The travel pillow has an interior shell of a semi-stiff unitary construction. There is a head support region defining a head supporting space for supporting the user's head, a neck support region defining a neck supporting space for supporting the user's neck posteriorly, an enlarged portion bridging together the head support region and the neck support region, the enlarged portion varying in radius from the head support region to the neck support region all elements functioning together as a single unit to maintain the columnar alignment of the user's head directly above the user's neck, and lobes extending upwardly on either side of the head support region to support the head at the intersection of the occipital bone, parietal bone and temporal bones on either side of the head to prevent lateral bending of the neck. The pillow is placed between the user and the seat back, wherein the pillow is held in place during use by the user's weight resting against the seat back. The head support region may be sized and shaped to match the approximate shape of the back of the user's head. The head support region may be transversely curved about the user's vertebral axis and is cut away at the user's occiput such that the user's head rests directly against the seat headrest.

A variable parietal / visceral pleural coupling may be utilized to create an air-tight seal in the pleural space between the parietal and visceral pleura. This coupling may be utilized to create a seal for other implantable devices.

The present invention is to provide a head relaxing pillow, which is made of an elastic material and includes a supporting main body having a top for supporting the neck of a user who lies face up and a bottom concavely provided with a recess, two contact portions each having one end connected to one of the two corresponding ends of the supporting main body and the other end corresponding in configuration to one of the user's parietal bones, and a pressing portion extending from one side of the supporting main body and located between the contact portions. The supporting main body is provided with two sunken portions which are adjacent to two corresponding ends thereof respectively. Thus, when the user's neck and head are resting on the supporting main body and the contact portions respectively, the two sunken portions are corresponding in position to the user's temporal bones respectively.

The invention discloses a helmet stabilizing device for emergency rescue and fire fighting. The structure comprises goggles, a protective ring, a linkage box, a stabilizing device, and a connecting plate. The goggles are vertically installed inside the stabilizing device through a connecting shaft, and the protective ring It has an integrated structure with the stabilizing device. There are two linkage boxes and they are horizontally installed on the left and right sides of the stabilizing device. The present invention pushes the engaging anti-pressure plate to move through the connecting tube to stabilize the structure of the top of the helmet and through the engaging anti-pressure The pressing plate moves and pulls the zipper belt to drag the ball, and squeezes the zigzag slide plate through the ball, so that the zigzagging slide plate pushes the positioning structural plate to position the occipital bone, and the cushion plate to position the parietal bone, stabilizing the positioning of the push plate to the temporal bone Position the occipital bone with the positioning structural plate, so that the main stress points of the skull fit the helmet, ensure the stability of the internal structure of the helmet, and protect the head from damage to the helmet and head injury due to the unstable structure of the helmet.

The invention relates to the field of medical auxiliary equipment, in particular to a brain nerve maintenance device and control method after brain surgery. The brain nerve maintenance device after brain surgery of the present invention comprises: a shell, the shell is hemispherical, and the occipital bone support plate, the parietal bone support plate, the frontal bone support plate, the sphenoid bone support plate and the temporal bone support plate are all arranged on the In the shell; the liquid bag is set in the shell and located in the gap, the liquid bag is connected with the liquid circulation pipeline, and the liquid circulation line is connected with a heat exchanger in series; the occipital bone support plate, the parietal bone support plate, the frontal bone support plate, and the sphenoid bone support plate And at least one of the temporal bone support plate is provided with a pressure sensor; and at least one of the occipital bone support plate, the parietal bone support plate, the frontal bone support plate, the sphenoid bone support plate and the temporal bone support plate is provided with a temperature sensor; the controller, and the temperature sensor , the pressure sensor and the flow valve communication connection of the heat exchanger. Through the above setting method, the liquid sac can exchange heat with the head to realize intracranial temperature regulation.

The invention discloses a brain nerve maintenance device after brain surgery, which comprises an inner protective pad, a middle air bag, an outer cooling shell and a bottom fixing ring. The inner protective pad includes a frontal bone pad, a parietal bone pad, an occipital bone pad, and a temporal bone pad. Pad and sphenoid bone pad, the frontal bone pad, parietal bone pad, occipital bone pad, temporal bone pad and sphenoid bone pad are fixedly connected by a locking fixture and form a three-layer protective structure with the middle airbag and the external cooling shell. The brain nerve maintenance device after brain surgery, by simulating the bone structure of the human brain, adopts a block structure design to make the contact between the product and the head closer, and it is easy to disassemble and assemble. Through the setting of the middle airbag, it can be used Massage and protect the skull through pressurization or decompression, and the inner protective pad is made of silicone, which can be in gentle contact with the head, thereby preventing pressure sores, protecting the brain tissue structure, and improving the safety protection ability of the product.
