DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1-Figure 7 As shown:

[0041] An inflatable oxygen inhalation system for geriatric cardiology includes an oxygen mask 101, and a mounting plate 102 is arranged above the oxygen mask 101;

[0042] Elastic bands 103 are provided at both ends of the mounting plate 102, and one end of the two sets of elastic bands 103 are connected with hook-surface Velcro 104 and fleece-surface Velcro 105 respectively through metal buttons;

[0043] A housing cover 106 is fixed to the upper surface of the mounting plate 102, and a gas pipe 107 is fixedly connected to the surface of the housing cover 106, and an air bag 108 is fixedly installed at the other end of the gas pipe 107, and a hose 109 is fixedly connected to the other end of the air bag 108;

[0044] A transfer tube 110 is provided between the gas delivery pipe 107 and the hose 109, a control valve 111 is installed inside the transfer tube 110, and a control valve 2 112 is installed on the side of the hose 109 close to the air bag 108;

[0045] The mounting plate 102 has a socket for the oxygen mask 101 to be inserted therein, and the cannula of the oxygen mask 101 is inserted therein. A cover plate 113 is provided at the socket provided on the mounting plate 102, and a plurality of groups of circular air holes are provided on the surface of the cover plate 113, and a sealing ring 114 is fixed to the inner side wall of the cover plate 113;

[0046] A self-sealing mechanism 3 is installed inside the housing cover 106. After the oxygen mask 101 is removed, the oxygen delivery is automatically blocked by the self-sealing mechanism 3.

[0047] The self-sealing mechanism 3 includes a conical block 302 disposed in the cavity of the housing cover 106 and a telescopic rod 304 fixed between the conical block 302 and the housing cover 106;

[0048] A spring 4 303 is wound around the surface of the telescopic rod 2 304, and the two ends of the spring 4 303 are respectively fixedly connected to the housing cover 106 and the conical block 302. A fixed column 301 for sealing the gas in the chamber of the housing cover 106 is fixed below the conical block 302. An air inlet hole adapted to the conical block 302 is opened inside the fixed column 301. The conical block 302 is inserted into the air inlet hole opened by the fixed column 301, and is used to block the chamber of the housing cover 106 to achieve oxygen blocking.

[0049] A connecting rod 305 is fixed between the conical block 302 and the cover plate 113;

[0050] The two ends of the transfer tube 110 are respectively fixed and connected to the gas delivery pipe 107 and the hose 109. The mounting plate 102 is provided with a limit groove at the insertion hole for the cover plate 113 to slide. The cover plate 113 can be slidably connected in the limit groove provided in the mounting plate 102.

[0051] The outer surface of the cover plate 113 is fixed with a rubber sleeve, which increases the sealing of the connection between the mounting plate 102 and the cover plate 113 . A plurality of groups of circular air holes are centrally arranged and correspond to the cannula of the oxygen mask 101 .

[0052] In this embodiment: when using the inflatable oxygen inhalation system for geriatric cardiology, first connect one end of the hose 109 to the oxygen supply source, then adhere the hook-surface Velcro 104 and the fleece-surface Velcro 105, and form an annular sleeve through the hook-surface Velcro 104, the fleece-surface Velcro 105, the mounting plate 102 and the two sets of elastic bands 103, and then put it on the face of the patient;

[0053] By different bonding positions of the hook surface Velcro 104 and the fleece surface Velcro 105, the diameters of the formed annular sleeves are different, so that different people can wear the device, thereby improving the flexibility and practicality of the device and achieving the most comfortable wearing effect;

[0054] Then, the mounting plate 102 is pulled, and then the mounting plate 102 pulls the elastic band 103 elastically, so that a certain distance is generated between the mounting plate 102 and the mouth, and then the oxygen mask 101 is placed on the patient's mouth, and the intubation part of the oxygen mask 101 is aligned with the insertion hole of the mounting plate 102, and then the mounting plate 102 is released. At this time, the elastic force of the elastic band 103 is restored to pull the mounting plate 102 downward, and the mounting plate 102 generates downward pressure on the oxygen mask 101, so that the oxygen mask 101 is inserted into the insertion hole opened on the mounting plate 102 and contacts the side wall of the cover plate 113, and a sealing ring 114 is provided between the cover plate 113 and the intubation tube of the oxygen mask 101, so as to increase the sealing performance of the connection between the cover plate 113 and the oxygen mask 101;

[0055] The cannula of the oxygen mask 101 pushes the cover plate 113 upwards, and at this time, the cover plate 113 pushes the conical block 302 upwards through the connecting rod 305, and the conical block 302 compresses the spring 4 303 and the telescopic rod 2 304, so that the conical block 302 is separated from the air inlet hole opened by the fixed column 301, thereby releasing the blockage of the chamber of the housing cover 106;

[0056] Then, the oxygen supply source is turned on, and the oxygen is transported to the transfer tube 110 through the hose 109, and then transported to the air pipe 107 through the transfer tube 110, and then transported to the chamber of the housing cover 106 through the air pipe 107, and then enters the oxygen mask 101 along the air inlet pipe of the fixed column 301 and the round air hole of the cover plate 113, and oxygen is supplied to the patient through the oxygen mask 101;

[0057] When the electric drive of the oxygen supply source is damaged, the control valve 111 is turned to block the transfer tube 110, and then the control valve 2 112 is opened to release the blockage of one end of the airbag 108. At this time, the oxygen in the hose 109 enters the airbag 108. By pressing the airbag 108, when the airbag 108 is compressed, the oxygen inside the airbag 108 is forced to be squeezed into the air pipe 107, and then transported to the shell cover 106, and then transported to the oxygen mask 101 to supply oxygen to the elderly. This design can flexibly choose manual or electric oxygen supply according to actual conditions and needs. Electric oxygen supply can be used when the power supply is sufficient and the equipment is available; when the power is insufficient or the equipment fails, it can be quickly switched to manual oxygen supply. In an emergency, manually pressing the airbag 108 can quickly provide oxygen to the patient and buy precious time for rescue;

[0058] When the oxygen mask 101 needs to be replaced, one hand pulls the mounting plate 102 to stretch the elastic band 103, and the other hand holds the oxygen mask 101 until the oxygen mask 101 is pulled out of the mounting plate 102. At this time, the oxygen mask 101 releases the squeeze on the cover plate 113, thereby releasing the squeeze on the conical block 302, the spring four 303 and the telescopic rod two 304. At this time, the spring four 303 rebounds and drives the conical block 302 to be inserted into the air inlet hole opened by the fixing column 301 to block the chamber of the shell cover 106. Therefore, after the oxygen mask 101 is pulled out, the automatic blocking function can prevent oxygen or gas from leaking into the environment after the oxygen mask 101 is pulled out, thereby saving resources and reducing waste, and there is no need to shut down the oxygen supply source, reducing the operation time, avoiding unnecessary time delays, and improving the use effect of the device;

[0059] The oxygen mask 101 is installed by directly plugging and unplugging it. The quick disassembly and assembly design simplifies the operation process, allowing medical staff or rescue personnel to easily install or replace the oxygen mask 101, thereby improving the use effect of this operation.

[0060] Going further;

[0061] In an optional embodiment, the lower surface of the mounting plate 102 is fixed with symmetrically arranged telescopic rods 116, the other end of the telescopic rods 116 is fixed with a bonding plate 117, a spring 115 is wound around the surface of the telescopic rods 116, the two ends of the spring 115 are respectively fixedly connected to the mounting plate 102 and the bonding plate 117, and a silicone pad is fixed to the bonding surface of the bonding plate 117 close to the adapter tube 110.

[0062] In this embodiment: the restoring elastic force of the elastic band 103 causes the mounting plate 102 to be pulled downward, and the mounting plate 102 generates downward pressure on the oxygen mask 101. At this time, the telescopic rod 116 and the spring 115 are compressed. The rebound force of the spring 115 can drive the bonding plate 117 to fit tightly with the oxygen mask 101. At the same time, a silicone pad is fixed to the bonding surface of the bonding plate 117 close to the adapter tube 110, which can increase the friction between the bonding plate 117 and the oxygen mask 101 and improve the wearing stability of the oxygen mask 101.

[0063] Going further;

[0064] In an optional embodiment, a locking mechanism 2 for convenient disassembly and assembly of the elastic band 103 is installed on the mounting plate 102;

[0065] The locking mechanism 2 includes bayonet holes provided on both sides of the mounting plate 102, a connecting rod 201 provided at the bayonet holes, and a sliding sleeve 202 provided at one end of the connecting rod 201;

[0066] One end of the connecting rod 201 is hinged to the mounting plate 102 through a hinge shaft, a sliding groove adapted to the connecting rod 201 is provided on one side of the sliding sleeve 202, the sliding sleeve 202 and the connecting rod 201 are slidably connected through the sliding groove, a spring 203 is fixed between the sliding sleeve 202 and the connecting rod 201, a locking hole adapted to the sliding sleeve 202 is provided on one side of the mounting plate 102, the sliding sleeve 202 is inserted into the locking hole provided on the mounting plate 102, and is used for connecting and locking the connecting rod 201 and the mounting plate 102, and one end of the elastic band 103 close to the mounting plate 102 is designed in a ring structure, and the ring of the elastic band 103 is sleeved on the connecting rod 201;

[0067] There are multiple groups of top columns 204 sliding on the connecting rod 201, and a spring 205 is fixed between the top column 204 and the connecting rod 201. The surface of the connecting rod 201 is provided with a moving groove adapted to the top column 204, and the top column 204 and the connecting rod 201 are slidably connected through the moving groove.

[0068] In this embodiment: when the elastic band 103 is pulled for a long time and elastic fatigue occurs and needs to be replaced, the sliding sleeve 202 is slid and then slides on the connecting rod 201, and the spring 203 is compressed, so that the sliding sleeve 202 is disengaged from the lock hole provided in the mounting plate 102, thereby releasing the obstruction of the connecting rod 201, and then the connecting rod 201 is folded to a certain angle, and then the elastic band 103 can be removed from the connecting rod 201, and a new elastic band 103 is put on the connecting rod 201, and then the sliding sleeve 202 is inserted into the lock hole again to lock the connecting rod 201, so as to facilitate the rapid replacement of the elastic band 103, improve the replacement efficiency, and meet the actual use needs;

[0069] The top column 204 is subjected to the elastic force of the spring three 205, so that the top column 204 bulges outward, thereby squeezing the inside of the ring sleeve of the elastic band 103. The generated squeezing force can increase the friction force connecting the connecting rod 201 and the elastic band 103, and improve the installation stability of the elastic band 103.

[0070] The present invention also provides a control method for an inflatable oxygen inhalation system for geriatric cardiology, comprising the following steps:

[0071] S1, connecting the hose 109 to the oxygen supply source;

[0072] S2, then the hook surface Velcro 104 and the fleece surface Velcro 105 are bonded together, and the hook surface Velcro 104, the fleece surface Velcro 105, the mounting plate 102 and the two sets of elastic bands 103 form an annular sleeve, and the sleeve is put on the face of the elderly patient;

[0073] S3, pull the mounting plate 102, and then the mounting plate 102 pulls the elastic band 103 elastically, so that the mounting plate 102 has a certain distance relative to the mouth, and then the oxygen mask 101 is placed on the patient's mouth, and the mounting plate 102 is loosened, and the oxygen mask 101 is inserted into the jack provided on the mounting plate 102, and contacts with the sealing ring 114 on the cover plate 113, and is plugged and installed;
