Abstract
Description
Technical Field
[0001] This utility model relates to breathing training equipment, and in particular to a breathing trainer. Background Technology
[0002] Patients with pulmonary dysfunction often require respiratory training devices during rehabilitation. Most existing clinical training devices use a three-ball type. The problem with this type of device is that the three balls are located within a sealed chamber. When patients perform breathing exercises, they inevitably blow air containing moisture into the chamber. Over time, this chamber becomes a breeding ground for bacteria. When patients perform breathing exercises again, they are highly susceptible to inhaling these bacteria into their respiratory tract, which is very detrimental to the health of patients in the recovery period. Utility Model Content
[0003] The purpose of this invention is to provide a breathing trainer that, while having a breathing training function, is easy to clean, thus preventing the growth of bacteria from harming the patient's health.

[0006] tube body;
[0007] The blowing and suction mechanism is connected to the upper end of the tube, allowing the patient to blow or inhale air into the tube.
[0008] A spacer is coaxially disposed in the middle of the tube and fixedly connected to the tube by spokes. The spacer has a conical structure and its diameter gradually increases from top to bottom, so as to separate an outer channel with an inner diameter that gradually increases from top to bottom and an inner channel with an outer diameter that gradually increases from top to bottom in the tube.
[0009] An exhalation training mechanism includes a first rubber stopper and a first spring assembly. The first rubber stopper is slidably inserted into the inner channel, and the first spring assembly is connected to the upper end of the first rubber stopper to apply an upward pulling force to the first rubber stopper.

The upper end of the first guide rod passes through the spring A and is screwed with an adjusting nut A. The spring is in a compressed state under the action of the adjusting nut A. The lower end of the first guide rod is connected to the first rubber plug to apply an upward pulling force to the first rubber plug.
[0012] Preferably, the second spring assembly includes a second support rod mounted inside the tube, with a spring B disposed below the second support rod. A second guide rod extending axially along the tube is also slidably inserted into the second support rod.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] like Figures 1-5The breathing trainer shown includes a tube 1 that extends axially through the tube, with a blowing and inhaling mechanism 2 connected to one end. Specifically, the blowing and inhaling mechanism 2 consists of a sealing cap screwed to the upper end of the tube 1, a flexible tube connected to the sealing cap, and a mouthpiece connected to the flexible tube. When performing breathing training, the patient simply blows and exhales into the tube 1 by placing their mouth over the mouthpiece.
[0030] Meanwhile, a spacer 3 is also provided inside the tube body 1. The spacer 3 is fixedly connected to the inner wall of the tube body by at least one spoke 31. It should be noted that the spacer is a conical sleeve. Specifically, the diameter of the spacer gradually increases from top to bottom, thereby cooperating with the tube body to divide the space inside the tube body where the spacer is located into an outer channel with a gradually decreasing inner diameter from top to bottom and an inner channel with a gradually increasing outer diameter from top to bottom.
[0031] In addition, the tube body 1 is also equipped with an exhalation training mechanism 4 that can be opened during exhalation training and an inhalation training structure 5 that can be opened during inhalation training.
[0032] Specifically, in this embodiment, the exhalation training mechanism 4 includes a first rubber stopper 41 and a first spring assembly 42 connected to the first rubber stopper. The first rubber stopper is structurally adapted to the outer channel; that is, the first rubber stopper 41 is a frustoconical structure that can be sealed and slidably inserted into the inner channel. The first rubber stopper also has a gradually decreasing diameter from top to bottom, so that when the patient exhales into the tube through the breathing mechanism 2, the first rubber stopper 41 can be pushed downwards, creating a gap between the septum and the first rubber stopper that allows gas to pass through.
[0033] It should be noted that, to ensure the first rubber stopper 41 can self-reset during breathing training, the first spring assembly 42 in this solution specifically includes a first guide rod 423 connected to the upper end face of the first rubber stopper 41. It also includes a first support rod 421 mounted in the tube body 1. The upper end of the first guide rod slides through the first support rod and is fitted with a spring A422. It should be noted that the upper end of the first guide rod 423 is a threaded section, on which an adjusting nut A424 is screwed. The spring A is compressed under the action of the adjusting nut A, so that the spring A can apply an upward thrust to the first guide rod 423. Under the action of this upward thrust, the first rubber stopper will initially seal against the inner surface of the spacer.
[0034] Furthermore, the inhalation training mechanism 5 in this solution specifically includes a second rubber plug 51 that is fitted and slidably inserted into the outer channel. A second spring assembly 52 is connected to the second rubber plug 51, capable of applying a downward pulling force to the second rubber plug. It should be noted that the second rubber plug 51 in this solution is specifically an annular structure adapted to the outer channel. Its basic requirement is that it can adapt to the shape requirement of the outer channel's inner diameter gradually increasing from top to bottom, so that it can slide into the outer channel in a sealed manner in the initial state.
[0035] Furthermore, it should be noted that, to ensure the second rubber stopper 51 can automatically reset during inhalation training, the second spring assembly 52 in this solution includes a second guide rod 523. This second guide rod is located in the lower region of the tube body and extends along the axial direction of the tube body. It should be noted that, to avoid affecting the descent of the first rubber stopper, the second guide rod 523 has a Y-shaped structure, and its upper end is fixedly connected to the lower surface of the second rubber stopper. Simultaneously, a second support rod 521 is also fixedly mounted in the lower region of the tube body 1, and the lower end of the second guide rod slides through this second support rod. Figure 3 As shown, a spring B522 is also installed below the second support rod, and this spring B is sleeved on the second guide rod. Subsequently, an adjusting nut B524 screwed to the lower end of the second guide rod compresses the spring B522. At this time, the spring B applies a downward thrust to the second guide rod, so that the second rubber plug 51 has a downward tendency to move, thereby ensuring that during inhalation training, the second rubber plug can automatically return to abutting against the spacer and maintain the separation of the tube body.
[0036] Furthermore, it should be noted that, based on the above-described implementation, this solution also includes the function of adjusting the intensity of the expiratory training mechanism and the inspiratory training mechanism. Specifically, only the compression degree of spring A and spring B needs to be adjusted. To facilitate the rotation of the adjusting nut A on the first guide rod and the adjusting nut B on the second guide rod, a lever 425 is provided on the lateral position of adjusting nut A and adjusting nut B respectively. Specifically, this lever extends radially. When intensity adjustment is required, the patient or medical staff only needs to move this lever to rotate adjusting nuts A / B.
[0037] Furthermore, to make the intensity of each breathing exercise more tangible, i.e., to accurately reflect the progress of the breathing exercise through numerical values, a spring scale 11 is also installed on the inner wall of the tube 1 in this design. The value of this spring scale corresponds to the elastic force value of spring A / B after compression. After rotating the adjusting nut A / B, the value indicated on the spring scale by the lever is the corresponding elastic force value of the compressed spring. Thus, medical staff / patients can intuitively and clearly understand the intensity of the breathing exercise through this scale value.
[0038] Finally, in order to clearly understand whether the first and second rubber plugs have reached an effective lifting height during each breathing exercise, the tube 1 in this design is made of transparent material, while the first rubber plug 41 and the second rubber plug 51 are made of two different colored rubber materials.
[0039] Working principle: When breathing training is needed, medical staff / patients adjust the adjusting nuts A / B to the appropriate position according to their own breathing capacity, and then connect the breathing mechanism to the upper end of the tube. Breathing training can then be achieved by blowing / inhaling air into the tube. Specifically:
[0040] During the exhalation training, the blown-in air increases the pressure in the tube space, which in turn acts on the first rubber stopper. The first rubber stopper then overcomes the tension from the first spring assembly and moves downward. During the movement, a gap is created between the first rubber stopper and the spacer, and the blown-in air is blown out through the gap to enable the exhalation training to continue.
[0041] During inspiratory training, the patient exhales air from the upper part of the tube, causing a decrease in air pressure. This atmospheric pressure then pushes the second rubber stopper upwards. At this point, a gap appears between the second rubber stopper and the septum, allowing external air to enter and enabling the inspiratory training to continue.
[0042] It should be noted that, in the above-mentioned expiratory and inspiratory training, the patient may be instructed to breathe to raise the first or second rubber stopper for 2 to 5 seconds, depending on the requirements.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
