Abstract: The present invention relates to an airbag structure comprising an airbag with multiple straight walls defining a hermetic interior; a plurality of baffles received in the interior of the airbag and a plurality of valves for communicating the interior with an air supply. Thus, contact area between the airbags and the human body is widely good,and the shape of the airbag structure of the mattress results in good comfort for a bed patient.

Abstract: A heat sink structure for air mattress mainly has a control unit having an air pump which is a powered device for supply of compressed air, and a controlling valve which is a fluid connector for selecting some of components to connect; and an air mattress having many groups of airbags arranged designedly while each airbag is a cannular structure which is expanded with pumping up and shrunken with draining off, and a heat sink layer which is a hollow structure; wherein the heat sink layer which is breathed and is connected to the controlling valve through an exhaust conduit; and each of the airbag groups is connected to the controlling valve through one conduit respectively and the controlling valve operated by the control unit selects any one group of the airbags to be connected for fluid flow and alternates the first conduit and the second conduit to connect with the air pump.

Abstract: An air cell provided for a mattress has two independent air chambers that are manufactured by die-casting at a same time. One of the independent air chambers is an adjustable air chamber, in which air can be alternately inputted and outputted through a pneumatic member to have the effect of promoting blood circulation of a person. The other independent air chamber is a supporting air chamber, which can support the body of the person with permanent air therein whenever the adjustable air chamber loses its function.

Abstract: A quick connector connects a pump and a fluid container is disclosed. The quick connector includes an upper component, a lower component, at least a telescopic tube, a connector body, and a soft cover. The upper component includes a first groove and a first buckle on one side thereof. The lower component has a second grove and a second buckle at locations corresponding to the first buckle and the first groove of the upper component, so that the upper component can be fitted to the lower component with the buckles and grooves. The telescopic tube is fitted between the upper component and the lower component to fasten the two components, and is connected to the fluid container at one end. The connector body includes an inner tube corresponding to the telescopic tube, and at least a movable board. The inner tube is partially overlaid inside telescopic tube, and is connected to the pump at one end. The movable board is fitted to the connector body with a turning shaft, and is rotary.

Abstract: An air mattress with alternate lifting function consists of a plurality of air pouches and side pouches. The side pouches are longitudinally located under the transverse air pouches. The side pouches are inflatable alternately to enable two sides of the air mattress moving up and down alternately to give a patient's body lain on the air mattress sideways exercises. The air pouches may be inflated alternately and synchronously with the inflation of the side pouches to alter pressing areas on the patient's body to prevent the patient from suffering harmful effect resulting from impeded blood circulation due to prolonged pressure exerting on the patient's body.

Abstract: A brake mechanism for a walker, essentially comprised of a brake disk with toothed peripheral is provided on the side of the wheel, a brake base allows relative displacement, and toothed section on the inner side of the brake base, wherein, said brake base as pushed by an elastic member holds with its toothed section against the toothed peripheral of the brake disk to brake the wheel in normal status, a handle is used to manipulate a brake cable to pull the brake base so to release the brake; furthermore, a turning block in the shape of a turntable is provided to accommodate the same brake cable connecting both brake handle, the turning block is further connected to another two brake cables to synchronously activate the brake mechanisms for the RH and the LH wheels; by pulling either brake handle, the synchronous release or brake of both brake mechanism can be achieved while allowing a 2-step brake.

Abstract: A renovated brake structure for an auxiliary moving device comprises a grip, a cover, a brake wire and a handle. The cover is secured to the handle and the grip is pivoted to the cover. The grip is secured to one end of the brake wire with a stud, whereas the other end of the brake wire having a spring to urge the grip to resume to original position. The grip comprises a pair of linking rods with a rail and a connecting pin on each rod. Each linking rod is connected at one end to a stud which is to secure with on end of a brake wire. A pair of holes are formed at the front respective ends of the grip for insertion of the pins. An arc trough is formed at one end of the grip with an elastic stopper at one end and a locating hole at the other end. A stop pin extending from the cover is inserted through the arc trough of the grip to secure the grip to the cover.

Abstract: An alternately inflated/deflated air bed being made by an arrangement of many air bag sets, each of them provided therein with a first air bag which is further provided therein with a second air bag. The first air bag thus is divided into two air chambers. An air pipe is provided on the first air bag for air intake and discharge. The second air bag is constantly kept inflated. The air bag sets are arranged in series. When the air bag sets of the odd and of the even numbers are alternately inflated/deflated by simultaneous discharge or intake of the two air chambers, the first air bags are inflated/deflated twice as much, so that a patient lying on the air bed obtains adequate ventilation by alternately changing contact points of his body with the air bed. When there is a power loss or machine failure which causes the first air bags to discharge, the second air bags support the patient to still feel comfortable.

Abstract: An air chamber structure for a medical air compressor, the chamber being provided between the pump and an air bed. Two flow guiding stubs are provided at an air input end to scatter air and render it to revolve in a storage chamber with a smaller space, the air is led into a larger pressure stabilizing chamber through a flow guiding port during continuous pumping of air into the storage chamber, and hence the output of the air can be stable and at a constant flow rate. An air output pipe is located on one edge opposite to the storage chamber, and air is uniformly spread in the pressure stabilizing chamber, and is put out from the output pipe at a constant flow rate, thus avoiding the disadvantage of generating resonance and wind noise in the inflated bed.

Abstract: The present disclosure is related to a front frame lifter for use in a walking supporter. When encountering obstacles on a path, a user can let down a footboard through a controlling plate and then lift the front frame by means of leverage by stepping on the footboard. Thus, the user can pass through the obstacles easily. Moreover, the lifting device can be applied to other carts such as a shopping cart or a perambulator with the same effect.
