DETAILED DESCRIPTION

[0029] The following will be combined with the attached embodiment of the present utility model Figure 1-11 , the technical solutions in the embodiments of the utility model are described in detail.

[0030] like Figure 1-2 As shown, a pressurized oxygen bag includes a protective cover 1 for fixing, a pressurizing component 2 for increasing the internal pressure of an airbag component 3, an airbag component 3 for squeezing an oxygen bag 5, an inflation component 4 for inflating the oxygen bag 5, an oxygen bag 5 for supplying oxygen, and a sensing component 6 for sensing the internal pressure of the oxygen bag 5. The pressurizing component 2 is located at the top of the protective cover 1 and is bonded to the surface of the protective cover 1. Therefore, when the protective cover 1 needs to be moved during actual use, the pressurizing component 2 will move with the protective cover 1 to avoid bending of the pipe of the pressurizing component 2 for inputting air into the airbag component 3, and the pressurizing component 2 is connected to the airbag component 3 inside the protective cover 1 through the pipe.

[0031] like Figure 1-2 As shown, when the airbag component 3 needs to apply pressure to the oxygen bag 5 from the outside, it is only necessary to start the pressurizing component 2, and the pressurizing component 2 will input air into the interior of the airbag component 3. When the airbag component 3 is deformed, it can apply pressure to the oxygen bag 5 so that the oxygen in the oxygen bag 5 can be discharged smoothly. The inflation component 4 is located on one side of the pressurizing component 2 and is also bonded to the surface of the protective cover 1, and the inflation component 4 is also connected to the oxygen bag 5 inside the protective cover 1 by a pipeline. Therefore, when it is necessary to supply oxygen to the patient, the medical staff can plug the oxygen supply tube into the inflation component 4, and the oxygen inside the oxygen bag 5 can be input into the interior of the oxygen supply tube through the inflation component 4. The sensing component 6 is located at the bottom of the inflation component 4 and is arranged inside the protective cover 1, and the sensing component 6 is connected to the inner wall of the protective cover 1.

[0032] like Figure 1-2 As shown, when the oxygen content inside the oxygen bag 5 is too low and oxygen needs to be supplied to the inside of the oxygen bag 5, the sensing component 6 will always monitor the pressure inside the oxygen bag 5 during the oxygen supply process to prevent the pressure inside the oxygen bag 5 from being too high and causing the oxygen bag 5 to rupture. The airbag component 3 is arranged inside the protective cover 1 along the length direction of the protective cover 1, and the airbag component 3 is also bonded to the inner wall of the protective cover 1. When the airbag component 3 is deformed, it can apply pressure to the oxygen bag 5 so that all the oxygen in the oxygen bag 5 can be discharged. At the same time, in the process of supplying oxygen to the inside of the oxygen bag 5, when the oxygen bag 5 is deformed, the airbag component 3 can limit and protect the oxygen bag 5 to prevent the oxygen bag 5 from continuing to expand outward after reaching the maximum inflation volume and causing explosion damage.

[0033] like Figure 1-2As shown, the airbag assembly 3 is bonded to the inner wall of the protective cover 1, so when the airbag assembly 3 needs to be replaced, it is only necessary to tear the airbag assembly 3 off the inner wall of the protective cover 1. The oxygen bag 5 is located inside the protective cover 1 and is arranged inside the airbag assembly 3 according to the length direction of the airbag assembly 3. The oxygen bag 5 is placed inside the airbag assembly 3 and is not connected to the airbag assembly 3. Therefore, when the oxygen bag 5 needs to be replaced, it is only necessary to take the oxygen bag 5 out of the airbag assembly 3. After the oxygen bag 5 is placed inside the airbag assembly 3, the opening of the protective cover 1 can be sealed by the zipper 11 at the opening of the protective cover 1. After the zipper 11 seals the opening of the protective cover 1, it can prevent the oxygen bag 5 from slipping out of the protective cover 1. When the pressurizing assembly 2 is working, the oxygen bag 5 will not fall off from the pressurizing assembly 2 due to the pressure applied by the pressurizing assembly 2.

[0034] like Figure 3 As shown, the sensing component 6 includes a pressure sensor 61 and a display screen 62. The pressure sensor 61 is arranged inside the protective cover 1 and below the inflatable component 4, and the pressure sensor 61 is pasted on the inner wall of the protective cover 1. The display screen 62 is arranged above the inflatable component 4 and fixed to the inflatable component 4 by screws, and the pressure sensor 61 is electrically connected to the display screen 62. When oxygen is filled into the oxygen bag 5, the oxygen bag 5 will be deformed and the internal pressure will gradually increase. The pressure sensor 61 will monitor the internal pressure of the oxygen bag 5 at all times to avoid the situation where the internal pressure of the oxygen bag 5 is too high and causes the oxygen bag 5 to rupture.

[0035] like Figure 3-4 As shown, the airbag assembly 3 includes an airbag 31, a fixing belt 32, a magic sticky fleece surface 33 and a magic sticky burr surface 34. The fixing belt 32 is arranged inside the protective cover 1 along the length direction of the protective cover 1, and the upper and lower ends of the fixing belt 32 are sewn with the magic sticky fleece surface 33 along the length direction of the fixing belt 32. The magic sticky burr surface 34 is sewn on the inner wall of the protective cover 1 at the position corresponding to the magic sticky fleece surface 33. The airbag 31 is arranged inside the fixing belt 32 and bonded to the inner wall of the fixing belt 32. Therefore, when it is necessary to fix the airbag 31, it only needs to bond the magic sticky fleece surface 33 to the magic sticky burr surface 34 to fix it. Because the airbag 31 is bonded to the inner wall of the fixing belt 32, after the magic sticky fleece surface 33 is bonded to the magic sticky burr surface 34, the airbag 31 can be fixed to the inside of the protective cover 1 through the fixing belt 32.

[0036] like Figure 3-4As shown, when the airbag 31 needs to be replaced, only the magic sticky soft fleece surface 33 and the magic sticky thorny fleece surface 34 need to be torn off to replace the fixing belt 32. The operation is practical and simple, and the magic sticky has strong viscosity. At the same time, the fixing belt 32 will not fall off the inner wall of the protective cover 1 easily. The air guide tube 22 of the pressurizing component 2 passes through the protective cover 1 and is connected to the airbag 31. The oxygen bag 5 is placed inside the airbag 31. Therefore, when the pressurizing component 2 is working, the air will be transmitted to the airbag 31 through the air guide tube 22. After the airbag 31 is deformed, pressure can be applied to the oxygen bag 5 from the outside. At the same time, when there is insufficient oxygen inside the oxygen bag 5 and oxygen needs to be supplied to the inside of the oxygen bag 5, causing the oxygen bag 5 to expand and deform, the fixing belt 32 will limit and protect the oxygen bag 5 during the expansion and deformation process to prevent the oxygen bag 5 from continuing to expand outward after reaching the maximum inflation volume and being exploded and damaged.

[0037] like Figure 5-7 As shown, the pressurizing assembly 2 includes an air pump 21, an air guide tube 22, a fixed cylinder 23, a sliding block 24, a bolt 25 and a nut 26. The air pump 21 is located at the top of the protective cover 1 and is bonded to the protective cover 1. One end of the air guide tube 22 is plugged into the air outlet of the air pump 21. The other end of the air guide tube 22 passes through the protective cover 1 and the air bag 31 and is arranged inside the fixed cylinder 23 and is connected to the sliding block 24. Therefore, when the air pump 21 is working, the compressed air flow can be input into the interior of the air bag 31 through the air guide tube 22, so that the air bag 31 can produce expansion deformation. The fixed cylinder 23 is laterally arranged inside the air bag 31. The fixing tube 23 is fixed to the inner wall of the airbag 31, through holes are provided at both ends of the fixing tube 23, a bolt 25 is vertically arranged inside each through hole, the top end of each group of bolts 25 passes through the airbag 31 and is vertically arranged outside the airbag 31, and a group of nuts 26 are arranged on each group of bolts 25, and the nuts 26 are threadedly connected to the bolts 25, and the sliding block 24 is horizontally slidably arranged inside the fixing tube 23 and bonded to the air guide tube 22, so that during use, the sliding block 24 can prevent the end of the air guide tube 22 from falling off from the inside of the fixing tube 23 due to the back and forth movement of the air guide tube 22.

[0038] like Figure 8-9As shown, the inflatable component 4 includes a first fixing block 41, a second fixing block 42, a cross 7, a conduit 43 and a fixing plate 44, the first fixing block 41 is located at the top of the protective cover 1 and is bonded to the protective cover 1, the first fixing block 41 is provided with a groove corresponding to the shape of the cross 7, the cross 7 is placed inside the groove, the second fixing block 42 is located above the first fixing block 41 and the inside of the second fixing block 42 is also provided with a groove corresponding to the shape of the cross 7, and the second fixing block 42 is connected to the first fixing block 41 by screws, and the bottom of the first fixing block 41 is bonded to the bottom of the first fixing block 41. It is connected to the protective cover 1, so after the four-way tube 7 is placed above the first fixing block 41 and the first fixing block 41 and the second fixing block 42 are connected by screws, the four-way tube 7 will not be displaced inside the first fixing block 41 and the second fixing block 42, one end of the catheter 43 is plugged into the fourth interface 74 of the four-way tube 7, and the other end of the catheter 43 passes through the protective cover 1 and is plugged into the oxygen bag 5, so that medical staff can directly supply oxygen to the inside of the oxygen bag 5 through the four-way tube 7, and the fixing plate 44 is located at one end of the catheter 43 close to the oxygen bag 5 and is vertically arranged inside the catheter 43.

[0039] like Figure 10-11 As shown, the cross-connection 7 includes a first interface 71, a second interface 72, a third interface 73, a fourth interface 74, an air pipe joint 75, a guide pipe 76, an electromagnetic stop valve 77, a pressure relief valve 78 and a quick connector 79. The first interface 71, the second interface 72 and the third interface 73 are vertically provided with grooves, and each group of grooves is vertically provided with an air pipe joint 75. One side of each group of air pipe joints 75 is plugged with a guide pipe 76, one end of the guide pipe 76 is plugged into the air pipe joint 75, and the other end of the guide pipe 76 is connected to the air pipe joint 75 through the four The fourth interface 74 through which the guide tube 7 passes is arranged inside the conduit 43, and the end of each guide tube 76 is plugged into the fixing plate 44, the electromagnetic stop valve 77 is threadedly connected to the first interface 71 and is located on the other side of the trachea connector 75, the pressure relief valve 78 is threadedly connected to the second interface 72 and is located on the other side of the trachea connector 75, and the quick connector 79 is threadedly connected to the third interface 73 and is located on the other side of the trachea connector 75. The quick connector 79 used can adopt the HI CUPLA series of MISUMI (China) Precision Machinery Trading Co., Ltd., which is an existing product and can be directly used.

[0040] like Figure 10-11As shown, when in use, after the patient's oxygen supply tube is plugged into the air outlet of the electromagnetic stop valve 77, the electromagnetic stop valve 77 can be opened according to the use requirements, so that the oxygen inside the oxygen bag 5 can be guided by the trachea connector 75 on one side of the electromagnetic stop valve 77 and the plugged guide tube 76, and then flow into the patient's oxygen supply tube through the inside of the electromagnetic stop valve 77. After the oxygen supply is completed and the oxygen inside the oxygen bag 5 is insufficient and oxygen supply is needed, the medical staff can plug the oxygen supply pipeline above the quick connector 79, and then the oxygen can be input into the oxygen bag 5 through the trachea connector 75 on one side of the quick connector 79 and the guide tube 76 on the trachea connector 75. At this time, the output flow rate controlled by the electromagnetic stop valve 77 remains unchanged.

[0041] like Figure 10-11 As shown, even if the oxygen supply causes the pressure inside the oxygen bag 5 to be too high, the patient will not feel uncomfortable, and if there is too much oxygen inside the oxygen bag 5 causing the pressure value inside the oxygen bag 5 to be too high, the flow rate of the electromagnetic shut-off valve 77 remains unchanged at this time, so the air flowing into the oxygen bag 5 through the quick connector 79 will enter the interior of the pressure relief valve 78 after being guided by the trachea connector 75 on one side of the pressure relief valve 78 and the guide tube 76 connected thereto. At this time, the pressure relief valve 78 will be opened by the oxygen inside the oxygen bag 5, and the excess oxygen inside the oxygen bag 5 will flow out from the pressure relief valve 78 until the pressure inside the oxygen bag 5 is lower than the critical value, at which time the pressure relief valve 78 will also be automatically closed, thereby reducing the pressure inside the oxygen bag 5 and avoiding the situation where the oxygen bag 5 bursts due to excessive pressure inside the oxygen bag 5.

[0042] The movement process of this embodiment is as follows: after the protective cover 1 is opened through the zipper 11 at the opening of the protective cover 1, the fixing belt 32 can be placed inside the protective cover 1, and after the fixing belt 32 is fixed by bonding the magic soft fleece surface 33 to the magic thorny fleece surface 34, the airway tube 22 can be plugged into the air outlet of the air pump 21, and then the oxygen bag 5 is placed inside the air bag 31 on the inner wall of the fixing belt 32, and then one end of the catheter 43 can be inserted into the oxygen tube through the through hole on the protective cover 1, and then the opening of the protective cover 1 can be sealed through the zipper 11, and then the electromagnetic stop valve 77 can be opened according to the needs of use, so that the oxygen inside the oxygen bag 5 can flow into the patient's oxygen supply tube through the electromagnetic stop valve 77.

[0043] When the pressure inside the oxygen bag 5 is too low and needs to be pressurized, the air pump 21 can be started, and the air compressed by the air pump 21 will flow into the interior of the airbag 31 through the air guide tube 22. At this time, the airbag 31 will deform and begin to squeeze the oxygen bag 5, so that the oxygen inside the oxygen bag 5 can flow into the interior of the electromagnetic stop valve 77 after being guided by the guide tube 76 and the trachea joint 75, and then flow into the patient's oxygen supply tube through the electromagnetic stop valve 77. When it is necessary to supply oxygen to the interior of the oxygen bag 5, first the air guide tube 22 is unplugged from the air pump 21 to allow all the air inside the airbag 31 to flow out, and then the oxygen supply tube can be plugged into the quick connector 79, and then the oxygen can be input into the interior of the oxygen bag 5 through the guide tube 76. During the oxygen supply process, the medical staff can check the pressure value inside the oxygen bag 5 through the display screen 62 on the second fixed block 42, and the oxygen supply to the interior of the oxygen bag 5 can be stopped after the required pressure value is reached.

[0044] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
