Problems solved by technology

[0006] However, in many cases, the difference in the gas storage status of the two airbags is not obvious. For the situation where the shape and size of the airbags are different, it is even more difficult to distinguish which airbag is more inflated. In this case, it will be difficult for the user to judge how to Adjust the two vent valves

Abstract

The invention provides a double-air-sac gas-filling device, and belongs to the field of medical product accessories. The double-air-sac gas-filling device comprises a rubber ball, wherein the rear end of the rubber ball is provided with a one-way air intake valve; the front end of the rubber ball is led out a gas transmission parent pipe; the rear end of the gas transmission parent pipe is divided into two branch pipes, each branch pipe is connected with a charging connector by virtue of a hose; and the gas transmission parent pipe is provided with one air vent valve. The double-air-sac gas-filling device disclosed by the invention can be used for automatically adjusting the gas filling speed of each air sac according to the gas storage state of the air sac, so that the gas storage capacity of each air sac is evenly increased, and a final double-air-sac structure achieves uniform and consistent ballooning degree.

Description

[0001] technical field [0002] The invention relates to the field of medical product accessories, in particular to a double air bag inflation device. [0003] Background technique [0004] Airbags are widely used in the medical field, and are mostly used in cushions, mattresses and other products. For a foldable medical cushion, there is usually more than one air cushion inside; for example, for a one-piece cushion that includes a bedding and a back cushion, each of the bedding and the back cushion contains an air cushion. Generally speaking, among foldable air cushion products, there are more double air cushion structures. [0005] For the inflation of the airbag, currently, a hand-held rubber ball device is mainly used. The rear end of the rubber ball is a one-way air intake valve, and the front end leads to an air delivery pipe. The end of the air delivery pipe is provided with an inflation nozzle for connecting the Gas mouth. On the air pipe of the more high-end rub...
