Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, including the gasbag base 1 of high right-low, gasbag base 1 upper end is equipped with the cambered surface of undercut, and the 1 rear end left and right sides of gasbag base is equipped with fixed band 2 respectively, and 1 lower extreme of gasbag base is equipped with a plurality of gasbag pads 3 of arranging along upper and lower direction, fixed connection between two adjacent gasbag pads 3, all is equipped with air duct 4 on the last lateral wall of every

gasbag pad

3, and 3 left ends of every gasbag pad and 1 left end of gasbag base all are equipped with gas tube 5.

In order to conveniently inflate and deflate the air bag base 1 and the air bag cushion 3, the structure of the inner part of the inflation tube 5 is the same as that of the valve core on the tire.

In order to adjust the height of the air bag base 1 conveniently, a one-way valve 6 with an upward opening is arranged in each air duct 4.

In order to fix the arm of the patient conveniently, the free end of the fixing band 2 is provided with a first magic tape 7, and the front end of the air bag base 1 is provided with a second magic tape 8 matched with the first magic tape 7.

In order to fix the airbag base 1 conveniently, two connecting belts 9 are respectively arranged on the front side and the rear side of the lower end of the airbag cushion 3 on the lowest side, a third magic tape 10 is arranged on the inner surface of the rear connecting belt 9, and a fourth magic tape 11 which can be matched with the third magic tape 10 is arranged on the outer surface of the front connecting belt 9.

In order to increase the friction force between the arm of the patient and the arc surface of the upper end of the air bag base 1 and play a role of anti-skidding, an anti-skidding cushion 12 is fixed on the arc surface of the upper end of the air bag base 1.

When the utility model is used, firstly, the connecting band 9 at the lower end of the air bag cushion 3 is used to fix the air bag base 1 at a proper position, so that the length direction of the air bag base 1 is the same as the arm direction of a patient, the free end of the connecting band 9 at the rear side is provided with a third magic tape 10, the free end of the connecting band 9 at the front side is provided with a fourth magic tape 11 which can be matched with the third magic tape 10, thereby facilitating the medical personnel to use the connecting band 9 to fix the air bag base 1;

then, the arm of the patient is placed in the downwards-sunken cambered surface at the upper end of the air bag base 1, the downwards-sunken cambered surface plays a role in wrapping and fixing the arm of the patient, meanwhile, the smooth cambered surface increases the comfort level of the patient during use, after the arm of the patient is placed at the upper end of the air bag base 1, the arm of the patient is fixed and stabilized through the fixing band 2, and as the free end of the fixing band 2 is provided with the first magic tape 7, the arm is conveniently connected with the second magic tape 8 at the front end of the air bag base 1, the arm of the patient can be conveniently fixed by medical personnel;
