Description

Air cushion

Technical Field

The invention relates to a medical instrument, in particular to an air cushion.

Background

The inflatable air cushion is used for solving the problems of limb swelling and pressure sore generation of local tissues after limb trauma or operation treatment, the limb swelling is a comprehensive result of combined action of multiple factors, the pressure sore is generated by long-term compression of a certain local tissue after lying in bed, and the raised limb can achieve the purposes of eliminating or reducing swelling and reducing the occurrence rate of the pressure sore. In the prior art, the air pillow is convex after being inflated, and the limbs are easy to slide off; when the limb is used, the limb is inconvenient to place and cannot be in full contact with the air pillow, so that a small section of the limb is in contact with the air pillow, and the far end of the limb is tilted. In order to solve the problems, the air cushion with a novel structure is provided, and the air cushion can be perfectly attached to the inner side of the knee joint, so that a patient feels comfortable to use, and the air cushion is convenient to disinfect and carry.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the following technical scheme: an air cushion is made of elastic material, preferably rubber material. The air cushion is the column type structure, including a horizontally bottom and bellied top, and the cross section at top is the arc, and the top up end is provided with the inner groovy. The air cushion is internally provided with an accommodating space, the air cushion is provided with an input pipe and an output pipe, the input pipe and the output pipe are respectively communicated with the accommodating space, and the input pipe is higher than the output pipe in the vertical direction.

Further, the inner groovy sets up the intermediate position at the top, and the inner groovy extends to the rear end handing-over department of top, bottom by the front end handing-over department of top, bottom. The inner groove is arc-shaped and concave from the left side and the right side to the bottom of the groove, and the depth of the inner groove is increased along with the rising of the position of the inner groove.

Further, the top portions are symmetrically arranged along the central axis.

Furthermore, the input pipe and the output pipe are respectively arranged on the left end surface and the right end surface of the top.

The utility model provides an inside accommodation space that is provided with of air cushion can fill gas or liquid to accommodation space through the input tube, and the air cushion is adjusted the air cushion height through adding the filler. The inner groove arranged on the air cushion can be perfectly attached to the inner side of the knee joint, and the human engineering design is met. As a further improvement of the utility model, the inner groove can be provided with wave stripes which can be horizontal or vertical, thereby preventing the knee joint from sliding when being placed on the inner groove.

Use the utility model provides a during the air cushion, be full of gas or liquid earlier with the air cushion, then let patient's knee joint place on the inner groovy, on the highest position of recess including the swing joint department of knee joint places, on the lower position of recess including all the other parts of knee joint drop naturally, keep fixed posture, can fill or emit gas or liquid to the air cushion according to patient's limbs body sensation at last, adjust comfortable height. The skin tissues at the joints of the limbs are fragile and easy to damage, and the air cushion filled with gas or liquid can buffer the pressure and reduce the damage. The arrangement of the inner groove can prevent the knee joint from sliding off the air cushion; the structure of inner groovy can let the knee joint fully contact with the air cushion, increases area of contact, reduces pressure and can reduce the physical factor that the pressure sore takes place, and the inner groovy can avoid unsettled discomfort of bringing moreover.

The utility model provides an air cushion simple structure does benefit to and carries, and accessible output tube emits the inside filler of air cushion when not using.
