Description

Technical Field

[0001] This invention relates to the field of breathing training technology, and in particular to a breathing training device. Background Technology

[0002] Breathing refers to the process of gas exchange between the human body and the external environment. Breathing training, also known as breath regulation or respiratory feedback, requires us to actively train according to a certain breathing pattern. Breathing training can increase our lung capacity and enhance respiratory muscle strength. Due to its advantages of being non-invasive, painless, simple, and convenient, breathing training is widely used in the field of respiratory nursing.

[0003] Existing expiratory training devices do not effectively filter the patient's exhaled air during expiratory training, allowing bacteria to enter the device with the air. Consequently, prolonged use of these devices can easily lead to cross-infection among patients. Furthermore, existing expiratory training devices do not allow for easy adjustment and control of the expiratory training intensity, nor do they facilitate direct observation of the patient's training and rehabilitation progress.

Button; Sliding seat 604 is vertically slidably disposed inside the fixed frame 601 via a dovetail groove, and the sliding seat 604 and the bolt rod 603 are configured for rotational connection; Control block 605 is fixedly disposed on both sides of the bottom of the sliding seat 604, and the control block 605 is configured as a right trapezoid; Connecting strip 606 is fixedly disposed on the outer side of the hypotenuse of the control block 605, and the connecting strip 606 is configured as a trapezoid; Clamping plate 607 is horizontally slidably disposed inside the fixed frame 601 via a dovetail groove; Rubber pad 608 is fixedly disposed inside the clamping plate 607, and the outer side of the rubber pad 608 is tightly fitted to the outer side of the connecting hose 501; Connecting block 609 is fixedly disposed on the outer side of the top of the clamping plate 607, and the connecting block 609 is configured as a straight The device is trapezoidal in shape, with the hypotenuse of the connecting block 609 fitting against the hypotenuse of the control block 605. A connecting strip 606 is slidably installed inside the connecting block 609. Two sets of connecting blocks 609, clamping plates 607, and control blocks 605 are used, and these sets are symmetrically arranged. Its specific function is to sterilize and filter the air inhaled by the patient into the training device by using the filter box 402 and its internal sterilized activated carbon. Furthermore, the locking block 105, locking hole 405, vertical rod 103, and spring allow for easy and convenient disassembly of the filter box 402, facilitating the replacement of the sterilized activated carbon inside.Furthermore, by utilizing the control block 605 and the connecting block 609, the two sets of clamps 607 can move simultaneously in opposite directions, achieving the effect of fixing the connecting hose 501 to the two sets of clamps 607 via the rubber pad 608. This facilitates easy and convenient disassembly and replacement of the connecting hose 501 and the breathing mask 502.

[0051] The specific usage and function of this embodiment: In this invention, during use, the end of the sterile connecting hose 501 is slidably placed outside the end of the connecting cover 401; then, by rotating the knob, the bolt rod 603 is rotated, causing the bolt rod 603 to drive the sliding seat 604 to slide downwards. The sliding seat 604, through two sets of control blocks 605 and connecting strips 606, drives two sets of connecting blocks 609 to slide inwards simultaneously, so that the two sets of clamping plates 607 clamp and fix the connecting hose 501 to the outside of the end of the connecting cover 401 through the rubber pads 608; The patient can exhale into the training cylinder 1 through a sterile breathing mask 502 and connecting hose 501. The exhaled air enters the filter box 402 through the connecting hose 501, where the sterile activated carbon inside the filter box 402 sterilizes and filters the patient's exhaled air. The sterilized air enters the training cylinder 1, causing the air to lift the piston plate 108 and piston column 107. The piston column 107 lifts the weight cylinder 201 containing the weight plate 205, thereby achieving the purpose of training the patient's exhalation process.

[0052] Rotating the threaded rod 302 via the knob causes the limiting seat 304 to move up and down outside the vertical cylinder 301 via the drive seat 303. The distance between the limiting seat 304 and the connecting seat 209 is then determined by the scale plate 305, ensuring the distance reaches a predetermined value. Consequently, as the weight-adding cylinder 201 rises, the connecting seat 209 rises along with it. When the connecting seat 209 touches the limiting seat 304, it indicates the patient's rehabilitation progress has reached the expected level. If the connecting seat 209 does not touch the limiting seat 304, it indicates the patient's rehabilitation progress has not reached the expected level, requiring increased training intensity.

[0053] When the training intensity needs to be increased, the weight plate 205 is slid onto the outside of the square column 203, and then the auxiliary plate 208 presses down on the weight plate 205, causing the connecting column 207 to automatically slide into the connecting groove 204 through the end spherical structure, spring, and baffle 206; thus fixing the weight plate 205 to the outside of the square column 203; thereby increasing the total weight inside the weight cylinder 201, requiring greater force to lift the weight cylinder 201; thus increasing the training intensity. When the training intensity needs to be reduced, because the thickness of the auxiliary plate 208 is set to half the thickness of the weight plate 205, there will be a gap between the upper and lower sets of auxiliary plates 208, which can be used to lift the weight plate 205 upwards through the gap and the auxiliary plate 208; thus, the weight plate 205 can be removed; thus reducing the training intensity.

[0054] When the sterilized activated carbon inside the filter box 402 needs to be replaced, the two sets of vertical rods 103 are lifted upward by the connecting rod 104, causing the two sets of locking blocks 105 to slide out of the locking holes 405 simultaneously. This allows the filter box 402 to be pulled out and the sterilized activated carbon inside the filter box 402 to be replaced via the handle 404 and the cover plate 403. After the sterilized activated carbon is replaced, the filter box 402 is pushed into the fixed box 4, causing the cover plate 403 to press against the locking blocks 105. The locking blocks 105 are subjected to force and slide upward through the outer inclined structure. When the outer surface of the cover plate 403 is in contact with the outer surface of the connecting cover 401, the spring element drives the locking blocks 105 to slide into the locking holes 405 via the vertical rod 103, thus fixing the cover plate 403 to the filter box 402. This completes the replacement of the sterilized activated carbon.
