In a further embodiment, the implant member has the shape of a sickle, the curvature of which is oriented ventrally and the interior of which is oriented dorsally. The attachment part is located at one end of the sickle while the opposite end of the sickle has a beak-type, tapering shape (5). At least one filling hole is provided between the sickle walls.

Abstract: A mask for supplying gas under pressure to the nasal airway of an infant human includes a manifold for supplying air to an aperture in the mask. A shaped membrane structure formed from a thin walled membrane defines an enclosure for receiving at least the nares of an infant human nose and a generally trapezoidal aperture adapted to fit around the nasal area of the infant human. Part of the membrane around the aperture is sufficiently flexible to mold to the shape of the infant human's nasal area or is contoured to generally match the contours around that nasal area while the membrane structure itself has sufficient rigidity to support the weight of the backing plate without collapsing. The provision of a generally trapezoidal rather than the generally triangular apertures for fitting around the nares provides a substantially improved fit when the mask is used with infants.

Abstract: A corrosion resistant Zn—Mg alloy implant material of high strength and toughness and absorbable by the human body, the alloy implant material having: 96 wt % to 99.98% Zn and 0.002 wt % to 4% Mg. The alloy implant material is applied to absorbable medical implants, particularly vascular stents and orthopedic implants. The alloy implant material can be absorbed in the human body environment, avoiding pain to patients caused by secondary surgery, and has much better corrosion resistance than magnesium alloy, and being able to achieve the two indexes of high corrosion resistance and high strength and toughness.

Abstract: A kind of absorbable high strength & toughness corrosion-resistant zinc alloy implant material for human body, the elemental constituent and quality percent: Ce0.001%-2%, Mg0.001%-2%, Ca0.001%-2%, Cu0.01%-3%, others are Zn. Above-mentioned zinc alloy material is prepared as absorbable medical implant by using conventional method in this field, especially for intravascular stent, orthopedic implants (bone nail or plate etc.). Zinc alloy material created by this invention has high corrosion-resistant and high strength & toughness, the medical implant prepared by this can be absorbed by the body without side effects.

Abstract: A mask for supplying gas under pressure to an airway of a human including a flexible manifold shell, an air inlet connected to an air delivery pipe, and at least two side walls which are at least partially formed by portions of the manifold shell. A flexible face contacting element defines an orifice to accommodate the nose of the human. Straps connected to the mask allow forces exerted by the straps to deform the manifold shell at least along X and Y axes, creating a variety of different orifice shapes. The face contacting part includes a flexible membrane allowing X and Y axis movement of the mask and movement of the mask along a Z axis between the user's face and the manifold shell. The flexible membrane may deform while retaining a gas seal against the face of a wearer.
