[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a disposable physiological saline with a simple pressurizing device as shown in Figures 1-4 the following, which includes a bag body 1, and also includes;

[0024] An airbag 2, the airbag 2 is sleeved in the middle of the bag body 1, and the airbag 2 is used to provide pressure to the bag body 1;

[0025] An adjusting assembly 3, the adjusting assembly 3 is arranged on one side of the airbag 2, the adjusting assembly 3 is used to adjust the air pressure inside the airbag 2, the adjusting assembly 3 includes a fixed tube 301 arranged on one side of the airbag 2, a connecting tube 302 is inserted and connected to one side of the fixed tube 301, a valve plate 303 is arranged on one side of the connecting tube 302, and a pushing member is arranged on one side of the valve plate 303;

[0026] A detection assembly 4, the detection assembly 4 is arranged on the top of the airbag 2, and the detection assembly 4 is used to measure the pressure inside the airbag 2.

[0027] It should be noted that the set hard material is a semi-plastic material with poor stretchability. The semi-plastic material is a composite of plastic and other materials (such as fibers, rubber, metals, etc.). Such a combination can optimize the performance and make the material have the lightness of plastic and the specific characteristics of other materials; the set bag body 1 is used to contain sterile physiological saline, and the amount filled can be 500 ml.

[0028] Specifically, a suspension strap 101 is arranged on the top of the bag body 1, and the suspension strap 101 is used to fix the position of the bag body 1.

[0029] It should be noted that both ends of the set suspension strap 101 are fixedly connected to the top end of the bag body 1. When it is necessary to fix the position of the bag body 1, the position of the bag body 1 is directly fixed through the suspension strap 101.

[0030] Specifically, the driving member includes a fixing bracket 304 fixedly connected to the inner wall of one side of the fixed pipe 301. A first spring 305 is arranged on the side of the fixing bracket 304 opposite to the valve plate 303. A guide rod 306 is fixedly connected to one side of the fixing bracket 304. The guide rod 306 is inserted through the middle of the first spring 305. A second sealing ring 308 is arranged at the connection between the connecting pipe 302 and the valve plate 303. A first sealing ring 307 is inserted through the middle of the valve plate 303. The guide rod 306 is inserted through the middle of the first sealing ring 307. A pressing block 309 for pressing the valve plate 303 is fixedly connected to one side of the valve plate 303. A receiving groove is formed on one side of the pressing block 309. The guide rod 306 is inserted through the inside of the receiving groove.

[0031] It should be noted that the first sealing ring 307 and the second sealing ring 308 are both made of rubber. They will deform after being squeezed, so as to fill the gaps at the joints of the objects, thus completing the sealing. The second sealing ring 308 is used to seal the connection between the connecting pipe 302 and the valve plate 303. Both sides of the arranged fixing bracket 304 are fixedly connected to the inner wall of the fixed pipe 301. The two ends of the arranged first spring 305 are respectively fixedly connected to the fixing bracket 304 and the valve plate 303. Thus, the position of the first spring 305 is restricted by the fixing bracket 304 and the valve plate 303, and the valve plate 303 is pushed towards the side of the connecting pipe 302 by the first spring 305. The arranged guide rod 306 is inserted through the middle of the valve plate 303. During use, the moving direction of the valve plate 303 is restricted by the guide rod 306 and its random swaying is restricted. The arranged connecting pipe 302 is used to connect the adjusting assembly 3 with a syringe or other device for inputting air. During use, other substances are received through the connecting pipe 302, and the valve plate 303 is pushed towards the side of the first spring 305 by the pushing of the gas, and the valve plate 303 is separated from one side of the connecting pipe 302, so that the gas enters the inside of the fixed pipe 301, and the gas is input into the inside of the airbag 2 through the fixed pipe 301, thereby increasing the air pressure inside the airbag 2. When the air supply stops, the first spring 305 pushes the valve plate 303 towards the side of the connecting pipe 302 by restoring its deformation, and blocks one side of the connecting pipe 302 through the valve plate 303, so that the gas cannot overflow through the connecting pipe 302, thus completing the increase of the air pressure inside the airbag 2. When it is necessary to reduce the air pressure inside the airbag 2, the valve plate 303 is driven to move towards the side of the first spring 305 through the pressing block 309, so that the valve plate 303 is separated from the connecting pipe 302, and the gas can flow out from the connecting pipe 302, thereby reducing the air pressure inside the airbag 2.

[0032] Specifically, the detection component 4 includes a fixed frame 401 inserted and connected to the top of the airbag 2. A piston 402 is inserted and connected inside the fixed frame 401. A scale 405 is provided on one side of the fixed frame 401. A limiting rod 403 is fixedly connected to the inner wall of the top end of the fixed frame 401. The limiting rod 403 is inserted and connected to the middle of the second spring 404 and the piston 402. A limiting block 406 is fixedly connected to the bottom end of the limiting rod 403.

[0033] It should be noted that the set fixed frame 401 is made of transparent plastic material and is used to observe the position of the piston 402 inside the fixed frame 401 during use. Sealing rings are provided at the joints of the set piston 402 with the fixed frame 401 and the limiting rod 403 to seal the joints of the piston 402 with the fixed frame 401 and the limiting rod 403. The position of the set limiting rod 403 is fixed to the inner wall of the top end of the fixed frame 401, and the piston 402 moves along the direction of the limiting rod 403 when moving. When the piston 402 moves downward and fits with the limiting block 406, the piston 402 will be restricted by the limiting block 406 and cannot continue to move downward. When the air pressure inside the airbag 2 changes and the air pressure increases, the pressure exerted by the gas on the piston 402 increases, pushing the piston 402 to move in the direction of the second spring 404. The moving distance of the piston 402 is observed through the scale 405, and the air pressure result inside the airbag 2 is obtained.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
