Problems solved by technology
[0003] In order to overcome the insufficient air output caused by the pressure drop of the existing oxygen bag during use and the insufficient storage of an oxygen bag to meet the long-term use, the technical problem mainly solved by the present invention is to provide an automatic replacement device based on the pressure of the leaf spring. Oxygen bag device, the automatic replacement oxygen bag device based on leaf spring pressure can not only exert a certain pressure on the oxygen bag to meet the requirements of continuous gas supply of the oxygen bag, but also provide a connection structure to expand the number of oxygen bags, so that Users can use multiple oxygen bags in series at the same time, so as to meet the requirements of long-term use of oxygen bags

The invention discloses an automatic oxygen bag replacing device based on pressure applied by leaf springs. The two leaf springs are arranged outside oxygen bags and are connected to form an ellipse to wrap the oxygen bags. A conduit and a liquid guide tube are further connected to the outer portion of each oxygen bag. Hydraulic switches, one-way valves, a connecting box and a conduit connector are sequentially mounted on the conduits. A liquid storage bag is arranged in each oxygen bag. Liquid used for driving the hydraulic switches is contained in the liquid storage bags. The oxygen storage conduit connector is connected to the outer portion of the connecting box. The conduits of all the oxygen bags are connected to the connecting box and supply oxygen to the outside through the conduit connector on the connecting box. By means of the automatic oxygen bag replacing device, multiple oxygen bags can supply oxygen continuously in the using process; when the oxygen in one oxygen bag is used up, the next oxygen bag can be opened automatically, and the oxygen in the next oxygen bag can be supplied to the outside through the connecting box and the conduit connector on the connecting box.
Description
technical field [0001] The invention relates to a device for replacing an oxygen bag, in particular to an automatic replacement device for an oxygen bag based on pressure exerted by a leaf spring. Background technique [0002] The currently widely sold oxygen bags on the market are composed of a simple air storage bag made of single-sided nylon coated rubber material and a rubber hollow conduit. The oxygen bag is inflated and deflated through the rubber conduit. When in use, the oxygen bag needs to be attached The catheter is docked with the breathing tube. Oxygen bags are generally used for family health oxygen inhalation and medical units to go out to rescue patients due to the convenience of carrying. However, in actual use, there is often a problem that the pressure of the oxygen bag decreases during use, and the gas output decreases accordingly, and when the use time is long, due to the limited storage of an oxygen bag, there may also be a problem that the total amount...
