Abstract: The present invention discloses an air mattress system including an inflatable air mattress, an air pipeline and a CPR valve device. The CPR valve device is configured to have a top that is not lower than a support surface near the CPR valve device in a state of use when a patient lies on the inflatable air mattress. The above provides deflation of the air mattress with desirable and significant operating guidance, such that the CPR valve device can be quickly located and operated, and the time need for a precedent procedure of the deflation of the inflatable air mattress can be effectively reduced. Thus, a patient can more promptly receive first aid to increase the CPR success rate, and this is conducive to improving quality and effects of emergency medical treatment.

Abstract: The present invention discloses an air mattress system including a first protection cell group disposed on one side of a support cell group. The first protection cell group includes a first middle cell having a height not exceeding a support surface, so as to preserve smooth routing paths for medical treatment pipelines and prevent obstructed flow of fluids. A front and a rear of the first protection cell group are respectively provided with a first front cell and a first rear cell, both of which are provided with bottom air chambers. When a patient needs to be transferred, the bottom air chambers are controlled to be deflated so that tops of the first front cell and the first rear cell are substantially lowered to be near the support surface to provide the patient with an unobstructed transition during the transfer.

Abstract: A patient interface including a headgear and a frame assembly is provided. The headgear is for maintaining the patient interface on a head of a patient. The frame assembly is for connecting to the headgear, and includes a main frame, and two side extension arms respectively extending from two sides of the main frame. When no force is applied to the side extension arm, an upper edge of a cheek contact section of the extension arm is closer to a mask central axis of the patient interface than a lower edge, so that the upper edge of the cheek contact section is away from an apex of a cheekbone of the patient when the patient interface is worn. The patient interface of the present invention better complies to a face by using the two side extension arms that conform to a profile of positions of upper halves of cheekbones of the face, and provides effects of good support and stability as well as dispersed weight and pressure.

Abstract: The present invention provides a patient interface including a cushion assembly, a headgear assembly, an elbow assembly and transition ring structure and a headgear secure assembly. The cushion assembly, the elbow assembly and the headgear secure assembly are assembled together by the transition ring structure. The cushion assembly is sealed with a face of a patient when in use. The headgear secure assembly is for connecting the headgear so as to secure the patient interface at the face of the patient when in use. The cushion assembly is provided with a cylindrical wall for delivering an air flow, and the cylindrical wall projects in two opposite directions along an axis of an opening thereof, so as to provide an air flow of a breathing chamber with a flow diversion guiding effect. Thus, the patient interface can be worn and used with better comfort and convenience.

Abstract: An air cell and an air mattress are provided. The air cell includes two opposing cell walls. When the air cell is inflated, an upper surface is formed at a top edge of the cell walls. Moreover, the air cell has a joining line extending along the top edge, which can be formed by joining the cell walls. The joining line has two semi-arc joining surfaces through arrangement of a wall junction position. In addition, the air mattress includes a plurality of air cells, a fluid generator, and a control system. The fluid generator is communicated with the air cells. The control system is configured to control the fluid generator to determine whether the air cells are inflated or deflated during use of the air mattress.

Abstract: The present invention discloses an electromagnetic air pump including an air chamber operable to be compressed or expanded. The air chamber is defined by a platform surface and a rubber cap operable to be pressed downward. The rubber cap includes a support and a cover. During the operation of the electromagnetic air pump, the cover is configured to bear against the support with the platform surface when the cover is pressed downward. When the air chamber is compressed or expanded, each pair of geometrically symmetrical parts of the cover corresponds to a pair of displacement changes relative to the platform surface, wherein a difference between the pair of displacement changes is not greater than 5%. Thus, the rubber cap is provided with an effect of a substantially uniform stress.

Abstract: Provided are an air cell device and an air mattress system thereof. The air cell device includes an air cell which has therein an upper connection segment and a lower connection segment. The upper connection segment and the lower connection segment each have a curved portion whereby the air cell is partitioned to become a multilayered air cell so as to mitigate air cell bending or air cell inversion, thereby improving the lying human being's comfort.
