Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a breathing recovery device with an internal diversion structure. Background Art

[0002] In the medical field, a breathing recovery device is a crucial medical device. It is mainly used to assist or replace the patient's spontaneous breathing to maintain normal gas exchange, ensuring that the body's tissues and organs can obtain sufficient oxygen supply and discharge carbon dioxide. The breathing recovery device is widely used in various scenarios such as the intensive care unit, operating room of the hospital, and home medical care. It plays an irreplaceable role for patient groups with respiratory failure, dyspnea, etc.

[0003] There are various types of existing breathing recovery devices, but most of the existing breathing recovery devices have similarities in working principles. They mainly operate through pumps or mechanical structures to intermittently supply air to help the user breathe.

[0004] However, this traditional breathing recovery device exposes some problems that need to be solved urgently in practical applications. First of all, when an emergency occurs that the user suddenly cannot breathe spontaneously during the use process, the existing breathing recovery device cannot issue an alarm in time to notify the medical staff to come to the rescue. This undoubtedly increases the risk of danger to the patient and may lead to delaying the best treatment opportunity. Secondly, during the process of driving breathing through pumps or mechanical structures, on the one hand, it is easy to cause damage to the user's lungs due to factors such as excessive air supply volume, affecting the patient's recovery process; on the other hand, such devices usually require continuous power supply to operate normally. This not only limits its use in power-free occasions, reducing the flexibility and convenience of use, but also is not energy-saving and environmentally friendly to a certain extent, which is contrary to the pursuit of green medical devices in modern society.

[0005] In summary, although the existing breathing recovery devices meet the patient's breathing support needs to a certain extent, there are still many deficiencies, and further technological innovation and improvement are urgently needed to improve their safety, reliability, and applicability.

The mounting block 701 is symmetrically provided with an air inlet passage 702 and an air outlet passage 703 that penetrate through both side end faces thereof, and the air inlet passage 702 and the air outlet passage 703 are used to connect the auxiliary hose 6. On the same side in the air inlet passage 702 and the air outlet passage 703, a card slot 704 is respectively provided, and a floating plate rod 705 is provided in each card slot 704. And the upper end of each floating plate rod 705 penetrates through the outer wall of the mounting block 701 and is located in the corresponding cylinder body 706. The cylinder bodies 706 are installed on both sides of the mounting bracket 707, and the mounting bracket 707 is connected to the outer wall of the mounting block 701. An adjusting spring 708 is provided in each cylinder body 706. One end of each adjusting spring 708 is connected to the end of the corresponding floating plate rod 705, and the other end of each adjusting spring 708 is connected to the movable plate 709 located in the corresponding cylinder body 706. A rotatable adjusting screw 710 is connected to each movable plate 709, and the end of each adjusting screw 710 penetrates through and is threadedly connected to the mounting bracket 707. In the middle area of the mounting bracket 707, a piston cylinder 712 is symmetrically connected to each side. And one end of each piston cylinder 712 is internally connected with a piston rod 711, and the end of the piston rod 711 is connected to the corresponding floating plate rod 705. The other end of each piston cylinder 712 communicates with the corresponding branch pipe 517.

[0031] The floating plate rod 705 is of a structure with a lower plate and an upper rod. The plate-like areas of the floating plate rod 705 located on both sides in the air inlet passage 702 and the air outlet passage 703 are arranged as inclined surfaces, and the upper rod-like area of the floating plate rod 705 is in sliding connection with the cylinder body 706.

[0032] Working principle: As shown in Figure 1 , first, move the oxygen supply main body 1 to the working area through the moving base 2. After the air is processed by the oxygen supply main body 1 and the air treatment box 3, driving heating is carried out. Wear the breathing mask 8 on the user's face. As the user breathes, when the user's breathing becomes weak due to poor breathing, during the process that the gas passes through the auxiliary hose 6 and penetrates through the air inlet passage 702 and the air outlet passage 703, the air flow is small and cannot effectively lift the floating plate rod 705 into the card slot 704. The adjusting spring 708 pushes the floating plate rod 705 to move downward, driving the piston rod 711 to move downward from the piston cylinder 712, generating a suction force, and sucking half of the hydraulic oil in the collection box 518 into the piston cylinder 712 through the branch pipe 517. The movable plate in the collection box 518 does not contact the trigger switch, and a warning is issued;

[0033] During this process, when the hydraulic oil passes through the branch pipe 517 and the box body 515, it drives the fan blade disc 516 to rotate. The fan blade disc 516 drives the winding roller frame 514 to rotate. The winding roller frame 514 winds the connecting rope 513. The connecting rope 513 pulls the movable pulley 511. Cooperating with the fixed pulley 512, with a relatively small force, the second connecting plate 510 can be pulled to move, thereby driving the connecting rod 506 and the piston plate 505 to displace in the air inlet cavity 502 and the air outlet cavity 503, so as to assist the user in breathing and ventilation, without the need for additional pumps, motor equipment, etc. for driving, saving energy and reducing emissions;

[0034] When the user is unable to breathe independently during use, the floating plate rods 705 in both the air inlet cavity 502 and the air outlet cavity 503 move outward from the cylinder body 706 under the action of the adjusting spring 708, driving the two piston rods 711 to move outward from the piston cylinder 712 at the same time. Therefore, all the hydraulic oil in the collection box 518 is pumped out. The movable plate in the collection box 518 will contact the trigger switch, send a signal to the external PLC control, issue a warning, and call for medical staff for rescue. At the same time, a command is sent to start the drive motor 519. The output shaft 520 drives the cam gear disc 521 to rotate. The cam gear disc 521 periodically meshes with the tooth block 522, driving the connecting rod 506 to move downward. At the same time, the buffer spring 523 is compressed. After the cam gear disc 521 disengages from the tooth block 522 on the connecting rod 506, the buffer spring 523 will push the connecting rod 506 to reset. This process repeats to achieve the rescue of the patient. This is the working principle of the breathing recovery device with the built-in diversion structure.
