Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to an emergency breathing device. Background Art

[0002] In the field of medical emergency, respiratory emergency devices are crucial to saving patients' lives. Traditional respiratory emergency devices have certain limitations. Some of them only have a single electric or manual assisted breathing function and cannot be flexibly switched for use in different scenarios.

[0003] For example, when encountering a power failure or a special emergency situation that requires rapid manual intervention, a single-function device is difficult to meet the needs. At the same time, some devices are not convenient enough in terms of air pressure adjustment, and cannot accurately adapt to the individual differences of different patients, affecting the first aid effect. Moreover, the fixing method of some breathing masks is not ideal. Either the fixation is not firm, which is easy to loosen during the first aid process and affect the ventilation effect; or it is inconvenient to install and disassemble, which is not conducive to rapid operation and subsequent maintenance. In addition, in terms of respiratory cycle control, some devices cannot achieve efficient automatic ventilation, which affects the smoothness of patients' breathing and the efficiency of first aid.

[0004] Therefore, a first aid breathing device is now proposed. Summary of the invention

[0005] In order to overcome the above defects of the prior art, the present invention provides an emergency breathing device to solve the problems raised in the above background technology.

[0007] Preferably, a plurality of exhaust ports are provided at the bottom end of the pump housing, and the exhaust ports are arranged in a ring shape.

[0008] Preferably, the pump membrane comprises an air inlet groove, an air inlet, a baffle membrane and a pressing edge, the air inlet is arranged at the bottom end of the air inlet groove, the baffle membrane is arranged at the top end of the air inlet groove, and the pressing edge is arranged at the bottom edge of the baffle membrane.

[0009] Preferably, a sleeve hole is opened in the middle of the strap, and one side of the sleeve hole is two separation structures, one separation structure is opened with a button hole, and the other separation structure is installed with a button, the two separation structures are connected by the buttons, and the two ends of the strap are provided with adhesive fasteners.

[0010] Preferably, the connecting assembly includes a straight pipe, a first end, a second end and a third end. A first end is provided at one end of the straight pipe for plugging and cooperating with the connecting pipe, a second end is provided at the other end of the straight pipe for plugging and cooperating with the manual inflation assembly, and a first one-way air valve is installed in the second end. A third end is provided at the bottom middle end of the straight pipe for connecting and cooperating with the air supply pipe.

[0011] Preferably, the manual inflation assembly includes a self-restoring airbag, an inflation head and a second one-way valve, one end of the self-restoring airbag is provided with an inflation head that is plugged into the second end, and the other end of the self-restoring airbag is provided with a second one-way valve.

[0012] Preferably, the expansion tube includes an air outlet pipe, an air inlet pipe, a locking ring, a silicone tube and a one-way valve interface. The air outlet pipe is connected to multiple air inlet pipes, each of which is fixed with a silicone tube through a locking ring, and a one-way valve interface is installed at the end of each silicone tube for reducing the air volume in the pipeline.

[0013] Preferably, an annular airbag is provided at the bottom of the breathing mask.

[0014] Preferably, the pressure-limiting valve is installed on a connecting pipe connected to the rear end of the breathing mask, and the pressure-limiting valve is used to adjust the maximum air pressure input to the patient, and the maximum air pressure range is 40 mmHg.

[0015] Preferably, a plurality of inverted conical annular grooves are provided on the air outlet pipe.

[0016] Technical effects and advantages of the present invention: 1. The device can not only use the air pump to automatically deliver air to assist single-person breathing first aid, but also provide manual inflation assistance through the manual inflation component. It can play a role when the air pump does not work or needs additional assistance, thereby improving the flexibility and reliability of first aid.

[0017] 2. By installing a pressure-limiting valve on the connecting pipe, the air pressure can be easily adjusted to meet the needs of different patients, which helps to improve the first aid effect.

[0018] 3. It can be detachably installed on the breathing mask through a strap. The separation structure design of the hole in the middle of the strap is connected by a button on one side, which makes it convenient to fix the breathing mask on the patient's face. The Velcro at both ends of the strap is easy to operate. At the same time, the strap is detachable for easy replacement.

[0019] 4. Through the special structure of the pump membrane in the pump housing and the exhaust port design, air can be blown into the breathing mask for the patient to breathe when the connecting tube takes in air, and the exhaled gas can be automatically discharged when the patient breathes, realizing the automatic ventilation function.

[0020] 5. Manual breathing first aid can be achieved by pressing the self-recovering airbag in the manual inflation component. When the air pump is running automatic first aid, pressing the self-recovering airbag can increase the air pressure to avoid insufficient oxygen content caused by too low air pressure of the air pump, thereby further improving the first aid effect. At the same time, the design of each end is convenient for different connection combinations with the connecting components and the air supply pipe to adapt to different first aid scenarios.

[0021] 6. By inserting the outlet pipe into the connecting pipe and connecting the manual inflation assembly to an inlet pipe, the other inlet pipes can be connected to gas or atomized agents, not limited to anesthetic gas. When supplying oxygen, oxygen is generated by the air pump and enters the self-recovering airbag. Then, it enters the inlet pipe from the silicone tube and mixes with the atomized agent before entering the breathing mask for the patient to breathe, thereby improving the first aid effect and the convenience of drug administration. When the air pump is not working, oxygen can also be supplied by pressing the self-recovering airbag to ensure the stability and safety of first aid.

[0022] 7. By opening a plurality of inverted conical annular grooves on the air outlet pipe, the plug-in sealing can be improved when connected with the connecting pipe, and at the same time, the firmness of the installation can be improved. In the setting of the connecting pipe, the overall size of the connecting pipe is shorter, which can reduce the volume of air in the pipe and prevent excessive compression of the gas from causing a significant decrease in air pressure.

DETAILED DESCRIPTION

[0032] 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.

[0033] As attached Figure 1-Figure 8 An emergency breathing apparatus is shown, comprising: A breathing mask 1, wherein a pump housing 2 is mounted on the breathing mask 1, a pump membrane 10 is mounted in the pump housing 2, the pump housing 2 is connected to a connecting pipe 3, and a pressure limiting valve 4 is mounted on the connecting pipe 3; A strap 5, wherein the strap 5 is detachably mounted on the breathing mask 1, and the strap 5 is used to fix the breathing mask 1 on the face; A manual inflation component 7, the manual inflation component 7 is used for manual inflation to assist breathing first aid; An air pump 9, the air pump 9 is used for automatically delivering air, and the air pump 9 is connected to an air delivery pipe 8; The connecting component 6 is used to connect the manual inflation component 7 and the air supply pipe 8.

[0034] The bottom end of the pump housing 2 is provided with a plurality of exhaust ports, and the exhaust ports are arranged in a ring shape.

[0035] The pump membrane 10 includes an air inlet groove 1001, an air inlet port 1002, a barrier membrane 1003 and a pressure edge 1004. The air inlet port 1002 is arranged at the bottom of the air inlet groove 1001, the barrier membrane 1003 is arranged at the top of the air inlet groove 1001, and the bottom edge of the barrier membrane 1003 is arranged at a pressure edge 1004.

[0036] During specific implementation, when air is taken in by the connecting pipe 3, air enters the pump housing 2, causing the air pressure at the top of the baffle 1003 to increase, thereby compressing the air inlet groove 1001, and the pressure edge 1004 at the bottom of the baffle 1003 is crimped onto the bottom end of the pump housing 2, so that each exhaust port is closed, so that air is blown into the breathing mask 1 from the air inlet 1002 for the patient to breathe and perform respiratory emergency. When the patient is ventilating, the air pressure at the top of the baffle 1003 decreases, and the gas exhaled by the patient inside the breathing mask 1 pushes up the baffle 1003, causing the pressure edge 1004 to rise, thereby opening each exhaust port, allowing the gas exhaled by the patient to be discharged from the exhaust port, and performing automatic ventilation.

[0037] A hole 11 is provided in the middle of the strap 5, and one side of the hole 11 is two separation structures, one of which is provided with a button hole, and the other is provided with a button 12. The two separation structures are connected by the button 12, and both ends of the strap 5 are provided with adhesive fasteners.

[0038] In specific implementation, the two separation structures are separated so that one side of the hole 11 can be opened, and the top of the respiratory mask 1 is placed into the hole 11, and the button 12 is passed through the button hole to connect the two separation structures to close the hole 11, and the strap 5 can be fixed on the respiratory mask 1, and then the respiratory mask 1 is placed on the patient's mouth and nose, and the strap 5 is wrapped around the back of the patient's head and fixed with Velcro, so that the respiratory mask 1 can be fixed on the patient's face. The fixation is convenient and the operation is simple, and the strap 5 is detachable, which is convenient for individual replacement.

[0039] The connecting component 6 includes a straight pipe 601, a first end 602, a second end 603 and a third end 604. One end of the straight pipe 601 is provided with a first end 602 which is plugged into and matched with the connecting pipe 3, and the other end of the straight pipe 601 is provided with a second end 603 which is plugged into and matched with the manual inflation component 7, and a first one-way air valve is installed in the second end 603. The bottom middle end of the straight pipe 601 is provided with a third end 604 which is connected and matched with the air supply pipe 8.

[0040] During specific implementation, the second end 603 is connected to the manual inflation component 7. When the air pump 9 is not working, the manual inflation component 7 can be pressed to provide respiratory emergency treatment to the patient. The third end 604 is connected to the air supply pipe 8. When the air pump 9 is working, respiratory emergency treatment can be directly and automatically provided to the patient, thereby improving the convenience of respiratory emergency treatment.

[0041] The manual inflation assembly 7 includes a self-restoring airbag 701, an inflation head 702, a second one-way valve 703 and a fourth terminal 704. One end of the self-restoring airbag 701 is provided with an inflation head 702 that is plugged into the second terminal 603, and the other end of the self-restoring airbag 701 is provided with a second one-way valve 703.

[0042] During specific implementation, by pressing the self-recovering airbag 701, external air can be sucked in from the second one-way valve 703, and the air can be transported to the breathing mask 1 from the used connecting component 6 or expansion tube 7 to achieve manual breathing first aid. At the same time, the inflation head 702 can be directly connected to the connecting tube 3. By pressing the self-recovering airbag 701, the air pressure can be increased, and the air can be directly transported to avoid the non-working state of the air pump 9. The connecting component 6 and the expansion tube 7 increase the pipeline path, thereby avoiding the waste of manually blown air, increasing the air pressure, and making the air delivery efficiency higher, thereby further improving the breathing first aid effect.

[0043] The expansion tube 13 includes an air outlet pipe 1301, an air inlet pipe 1302, a locking ring 1303, a silicone tube 1304 and a one-way valve interface 1305. The air outlet pipe 1301 is connected to multiple air inlet pipes 1302. Each of the air inlet pipes 1302 is fixed with a silicone tube 1304 through a locking ring 1303. A one-way valve interface 1305 is installed at the end of each silicone tube 1304 for reducing the air volume in the pipeline.

[0044] In a specific implementation, the outlet pipe 1301 is inserted into the connecting pipe 3, and the manual inflation assembly is connected to an inlet pipe 1302. The other inlet pipes 1302 can be connected to gas or atomized agents, not limited to anesthetic gas. When supplying oxygen, oxygen is generated by the air pump 9 and enters the self-recovering airbag 701. Then, it enters the inlet pipe 1302 from the silicone tube 1304 and mixes with the atomized agent before entering the breathing mask 1 for the patient to breathe. This can improve the first aid effect and the convenience of drug administration. When the air pump 9 is not working, oxygen can also be supplied by pressing the self-recovering airbag 701 to ensure the stability and safety of the first aid.

[0045] An annular air bag is arranged at the bottom of the breathing mask 1.

[0046] During specific implementation, by arranging an annular airbag at the bottom of the breathing mask 1, the breathing mask 1 can be better fitted to the patient's face. The annular airbag can produce deformation and can ensure that it is suitable for use by different patients.

[0047] The pressure limiting valve 4 is installed on the connecting pipe 3 connected to the rear end of the breathing mask 1. The pressure limiting valve 4 is used to adjust the maximum air pressure input to the patient. The maximum air pressure range is 40 mmHg. A plurality of inverted conical annular grooves are opened on the air outlet pipe 1301.

[0048] In specific implementation, by opening a plurality of inverted conical annular grooves on the air outlet pipe 1301, the plug-in sealing performance can be improved when connected with the connecting pipe 3, and at the same time, the firmness of the installation can be improved. In the setting of the connecting pipe 3, the overall size of the connecting pipe 3 is shorter, which can reduce the volume of air in the pipe and prevent excessive compression of the gas from causing a significant decrease in air pressure.
