Description

Technical Field

[0001] The utility model relates to the technical field of oxygen bags, in particular to an explosion-proof device based on medical oxygen bags. Background Art

[0002] Medical oxygen, the testing standard stipulates: oxygen purity ≥ 99.5%, pH, carbon monoxide, carbon dioxide, and other gaseous oxide contents are all qualified, and odorless. It is suitable for auxiliary treatment of respiratory diseases (such as asthma, bronchitis, cor pulmonale, etc.) and heart and cerebrovascular diseases (such as coronary heart disease, myocardial infarction, cerebral hemorrhage, cerebral infarction) caused by hypoxia to relieve its hypoxia symptoms; it can also be used for health care oxygen inhalation or rapid relief of fatigue after intense mental and physical labor.

[0003] At present, oxygen bags used in hospitals or medical institutions are usually composed of the following parts: rubber nylon initial belt rubber tube, air stop valve. The maximum pressure that oxygen bags can withstand is usually 10.6kPa. However, in hospital clinical work, especially when filling oxygen in the operating room, it is impossible to accurately judge the pressure of the gas filled into the oxygen bag. Once the pressure is too high, the oxygen bag will be damaged or even cause an explosion, creating invisible safety hazards. Utility Model Content

The inner side edge of the auxiliary guide tube 3 is fixedly provided with a pressure sensor 6. The pressure sensor 6 is fixedly arranged on the inner side edge of the auxiliary guide tube 3 away from one end of the side through hole 4, and the interior of the pressure sensor 6 is connected with the interior of the auxiliary guide tube 3. A one-way air intake guide rubber block 7 is fixedly arranged on the inner side edge of the main inflation pipe 2. The specifications and dimensions of the one-way air intake guide rubber block 7 are consistent with those of the one-way exhaust guide rubber block 5.

[0019] The working principle of the utility model is:

[0020] One end of the main inflation pipe 2 is plugged and set at the output end position of the inflation pump. After the inflation pump is turned on, the main inflation pipe 2 is used to inflate the interior of the main oxygen bag 1. Under the guidance of the one-way air inlet guide rubber block 7, the internal air of the main inflation pipe 2 can only flow in one direction toward the main oxygen bag 1. After the internal inflation of the main oxygen bag 1 reaches a specified pressure, the oxygen enters the auxiliary guide pipe 3 through the side through hole 4 and the one-way exhaust guide rubber block 5. Due to the direction restriction of the one-way exhaust guide rubber block 5, the oxygen can only form a one-way outflow movement toward the auxiliary guide pipe 3, so that the internal pressure sensor 6 is squeezed to form a specified pressure reminder effect, which effectively prevents the explosion hazard caused by excessive pressure during the oxygen bag inflation process.
