Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a backpack-type oxygen bag. Background Art

[0002] An oxygen bag, also known as a portable oxygen bag or emergency oxygen bag, is a portable device used in medical settings to provide additional oxygen support to patients.

[0003] The existing oxygen bag includes a bag body, an air inlet and an air outlet opened on the bag body, wherein the air inlet is sealedly connected to an oxygen supply tube for connecting to an external oxygen supply device, and the oxygen supply tube is provided with an adjustment switch for opening or closing and adjusting the input oxygen amount. The air outlet is sealedly connected to an oxygen outlet tube, and the end of the oxygen outlet tube is provided with a breathing valve. When in use, the oxygen supply tube is first connected to the external oxygen supply device, and then the adjustment switch is turned on to allow oxygen to be filled into the bag body. When the bag is full of oxygen, the adjustment switch is turned off, and the patient can inhale oxygen through the breathing valve.

[0004] Since there is no structure on the outer surface of the oxygen bag that is convenient for carrying, the oxygen bag must be held in the hand when using it, which is extremely inconvenient when the patient needs to move or perform other activities. In order to solve this technical problem, the Chinese utility model patent with publication number CN2041191858U discloses a dual-purpose portable oxygen absorption backpack, including: a bag body, an oxygen absorption bag, two shoulder straps, a handle and an elastic band; the oxygen absorption bag is detachably installed inside the bag body, the handle is installed at the upper end of the bag body, the two shoulder straps are respectively installed on both sides of the rear end of the bag body, and the elastic band is wrapped around the waist of the oxygen absorption bag. When in use, the oxygen absorption bag can be conveniently carried by placing it in the backpack.

[0005] However, in actual use, the above solution only uses the elastic band inside the backpack to fix the oxygen bag. When the oxygen bag is not filled with oxygen, the oxygen bag is in a flat or collapsed state, making it impossible for the elastic band to fix the oxygen bag. At this time, if the oxygen bag is filled with oxygen, the oxygen bag may shift or be compressed during the process of slow expansion, thereby affecting the oxygen filling effect. In addition, since the oxygen bag bulges when filled, it not only causes the volume of the backpack to expand, but also affects the user's activities and carrying comfort.

[0006] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0007] The utility model provides a backpack-type oxygen bag, which aims to solve the problems that the existing oxygen backpack cannot fix the oxygen bag and affects the user's activities and carrying comfort when the oxygen bag is filled.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A backpack-type oxygen bag comprises a backpack base, two sides of the backpack base are provided with folding frames for driving the backpack base to unfold or fold, an interior of the backpack base is provided with a storage space for accommodating the oxygen bag, a top of the backpack base is provided with a zipper for opening or closing the storage space, a bottom of the storage space is provided with a first ring surface, the bottom of the oxygen bag is provided with a first hook surface that is fastened with the first ring surface, an oxygen supply tube and an oxygen outlet tube are respectively sealed and connected to the top of the oxygen bag, and the oxygen supply tube and the oxygen outlet tube both pass through the backpack The top of the base body, and the end of the above-mentioned oxygen outlet pipe is provided with a breathing valve, and the above-mentioned oxygen supply pipe is provided with an adjusting switch; the back of the above-mentioned backpack base body is also provided with a first pad layer and a second pad layer connected to each other, and the above-mentioned first pad layer and the above-mentioned second pad layer together constitute an internal hollow sandwich structure, a foldable backboard assembly is provided in the sandwich structure, and the top of the first pad layer facing the second pad layer is provided with a second ring surface, and the side of the above-mentioned second pad layer facing the first pad layer is provided with a second hook surface that cooperates with the above-mentioned second ring surface; the side of the above-mentioned second pad layer facing away from the first pad layer is also provided with a shoulder strap.

[0010] Furthermore, the folding frame includes two cross-arranged base plates, and the two base plates are rotatably connected via a through-pin shaft.

[0011] Furthermore, the backboard assembly includes a plurality of backboards hingedly connected by hinges.

[0012] Furthermore, the backboard assembly includes a plurality of backboards hingedly connected by a flexible skeleton.

[0013] Furthermore, the backpack base is rectangular.

[0014] Furthermore, the backpack base is made of fireproof and heat-insulating material.

[0015] From the above description of the structure of the utility model, it can be seen that the utility model has the following advantages:

[0016] Firstly, the present invention provides folding frames on both sides of the backpack base that can drive the backpack base to expand or fold, which not only improves the convenience when carrying, but also increases the storage space of the backpack base to prevent the backpack base from bulging when the oxygen bag is filled. A first hook surface is provided at the bottom of the oxygen bag, and a first ring surface that cooperates with the first hook surface is provided at the bottom of the storage space of the backpack base, so as to achieve the effect of fixing the oxygen bag and prevent the oxygen bag from shifting when oxygen is filled. A foldable backboard assembly is provided in the sandwich structure on the back of the backpack base, which further reduces the impact of the oxygen bag on the carrying comfort when it is filled, improves the carrying experience of the oxygen backpack wearer, and occupies less space after storage, which is convenient for storage.

[0017] Secondly, the base material of the backpack of the present invention is a fireproof and heat-insulating material, which can avoid explosions caused by high temperatures when used at a fire scene, thereby improving safety in use. BRIEF DESCRIPTION OF THE DRAWINGS
