Abstract
Description
Technical Field
[0001] This utility model relates to the field of respiratory function training technology, and in particular to a respiratory training device for respiratory function training. Background Technology
[0002] Breathing training is divided into two types: inhalation training and exhalation training. Inhalation is an active process that requires active contraction to expand the chest cavity and reduce the pressure inside the lungs. When the pressure inside the lungs is lower than atmospheric pressure, air is drawn into the lungs. The mechanism of exhalation is the same as that of inhalation, which is due to the pressure difference. However, exhalation occurs because the pressure inside the lungs is greater than atmospheric pressure. Exhalation breathing training significantly improves the efficiency of gas exchange in the body.
[0003] In the prior art, such as Chinese Patent Publication No. CN217548927U, a breathing trainer is disclosed, including a ventilation base. A connecting cavity is formed in the upper side of the ventilation base, and a conversion cavity is formed in the lower side of the ventilation base. The connecting cavity and the conversion cavity are connected to each other. A rubber sealing block is snapped into the lower end of the connecting cavity. Rotary adjustment switches are movably connected to the lower sides of the left and right ends of the ventilation base, respectively. A snap-fit ring is snapped into the upper end of the connecting cavity. The lower end of a connecting tube is fixedly connected to the upper end of the snap-fit ring, and an exhalation tube is movably installed on the upper end of the connecting tube. When the snap-fit ring is snapped into the connecting cavity, the connecting tube is installed on the upper end of the ventilation base. The rubber sealing block moves downward and disengages from the connecting cavity. Two sets of springs are compressed, and the airflow is then discharged from the conversion cavity and from the air outlet corresponding to the arc-shaped groove. This breathing trainer has a simple, compact, and small structure, is easy to carry, and is suitable for exercise during the rehabilitation period of chronic respiratory diseases. It is also easy to adjust.
[0004] Although one of the aforementioned patents has a simple, compact, and small structure that is easy to carry and suitable for rehabilitation exercises during chronic respiratory diseases, and is also easy to adjust, the aforementioned respirator only has the function of rehabilitation training and does not have the function of assessing lung function improvement. Moreover, for some hemiplegic patients, it is easy to leak air when blowing air through the mouthpiece, resulting in poor breathing training effect and poor practicality. Utility Model Content
[0005] The purpose of this invention is to solve the problems that existing respirators only have the function of rehabilitation training and do not have the function of assessing lung function improvement. Moreover, for some hemiplegic patients, air leakage is easy when blowing air through the mouthpiece, resulting in poor breathing training effect and poor practicality. Therefore, this invention proposes a breathing trainer for breathing function training.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a breathing trainer for respiratory function training, comprising a lung flute body, a connecting pipe fixed to the output end of the lung flute body, a connecting pipe provided at the end of the connecting pipe away from the lung flute body, a mask fixed at the end of the connecting pipe away from the connecting pipe, brackets fixed at both ends of the outer wall of the lung flute body, a pressure plate provided inside the bracket, a limit plate fixed at both ends of the pressure plate, a spring fixed between the limit plate and the bracket, and a flow sensor installed on the outer wall of the connecting pipe.
[0007] Furthermore, a threaded groove is provided on the outer wall of the end of the connecting tube away from the main body of the lung flute, and a threaded sleeve matching the threaded groove is fixed to the end of the connecting tube facing the connecting tube.
[0008] Furthermore, a connecting plate is fixed on the outer wall of the connecting pipe, a sealing sleeve is fixed on the end of the connecting plate facing the connecting pipe, an outer sleeve is fixed on the outer wall of the connecting pipe, and a sealing groove matching the sealing sleeve is opened on the end of the outer sleeve facing the connecting pipe.
[0009] Furthermore, each end of the mask is fixed with a mounting bracket, and each mounting bracket is fitted with Velcro. The outer walls of the two Velcro straps are jointly fixed with a strap.
[0010] Furthermore, both ends of the bracket are provided with limiting grooves that match the limiting plate, and the spring is located in the limiting groove.
[0011] Furthermore, friction-enhancing sleeves are fixed on both sides of the support on the outer wall of the lung flute body.
[0012] Furthermore, a soft pad is fixed to the end of the pressure plate facing the main body of the lung flute.
[0013] Furthermore, the mask has an opening that matches the connecting tube.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] In this invention, the mouthpiece at one end of the traditional connecting sleeve is transformed into a mask-type mouthpiece by the addition of a face mask. This mask-type mouthpiece prevents air leakage when the patient blows, improving the training effect. Furthermore, the straps allow the mask to be securely attached to the user's face, preventing accidental drops and enhancing stability. Additionally, the device uses a flow sensor to accurately measure the airflow speed and flow rate during exhalation. By continuously monitoring the expiratory flow rate data, the device can observe whether the expiratory flow rate has increased after a period of lung flute training. Attached Figure Description

Detailed Implementation
[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1, as Figure 1 - Figure 4 As shown, this utility model provides a breathing trainer for respiratory function training, including a lung flute body 1, a connecting pipe 2 fixed to the output end of the lung flute body 1, a connecting pipe 5 provided at the end of the connecting pipe 2 away from the lung flute body 1, a mask 10 fixed at the end of the connecting pipe 5 away from the connecting pipe 2, brackets 15 fixed at both ends of the outer wall of the lung flute body 1, a pressure plate 17 provided inside the bracket 15, a limit plate 19 fixed at both ends of the pressure plate 17, a spring 20 fixed between the limit plate 19 and the bracket 15, and a flow sensor 14 installed on the outer wall of the connecting pipe 2.
[0024] The effect achieved by the entire embodiment 1 is that, in use, the connecting tube 2 is simply connected to the connecting tube 5 as needed. At this time, the user wears a mask 10 fixed at one end of the connecting tube 5 to perform exhalation exercises. Through the setting of the flow sensor 14, the airflow speed and flow rate during the user's exhalation can be accurately measured. By continuously monitoring the exhalation flow data, after a period of lung flute training, it can be observed whether the exhalation flow has increased. The user's hand holds the lung flute body 1, and the user's four fingers are placed between the support 15 and the lung flute body 1. The pressure plate 17 is pressed down under the push of the spring 20, thereby limiting the user's hand to a certain extent and preventing the lung flute body 1 from accidentally falling due to the user's loose grip, thus making it more stable.
[0025] Example 2, as Figure 1 - Figure 4 As shown, a screw groove 3 is provided on the outer wall of the end of the connecting pipe 2 away from the lung flute body 1. A screw sleeve 6 matching the screw groove 3 is fixed to the end of the connecting pipe 5 facing the connecting pipe 2. A connecting plate 7 is fixed on the outer wall of the connecting pipe 5. A sealing sleeve 8 is fixed to the end of the connecting plate 7 facing the connecting pipe 2. An outer sleeve 4 is fixed on the outer wall of the connecting pipe 2. A sealing groove 9 matching the sealing sleeve 8 is provided on the end of the outer sleeve 4 facing the connecting pipe 5. Mounting brackets 11 are fixed to both ends of the mask 10. Velcro 12 is sleeved in both mounting brackets 11. A strap 13 is fixed to the outer wall of both Velcro 12. Limiting grooves 21 matching the limiting plate 19 are provided at both ends of the bracket 15. A spring 20 is provided in the limiting groove 21. Friction-enhancing sleeves 16 are fixed on both sides of the bracket 15 on the outer wall of the lung flute body 1. A soft pad 18 is fixed to the end of the pressure plate 17 facing the lung flute body 1. An opening matching the connecting pipe 5 is provided inside the mask 10.
[0026] The overall effect of embodiment 2 is that, through the setting of the screw groove 3 and the screw sleeve 6, the connecting pipe 2 and the connecting pipe 5 can be threadedly connected. When the connecting pipe 2 and the connecting pipe 5 are threadedly connected, the sealing sleeve 8 will rotate into the sealing groove 9 opened at one end of the outer sleeve 4, thereby sealing the gap between the connecting pipe 2 and the connecting pipe 5, which is more practical. Through the setting of the soft pad 18, the user's hands can be cushioned and protected. Through the setting of the friction-enhancing sleeve 16, the friction force of the user holding the lung flute body 1 is enhanced. Through the setting of the Velcro 12 and the mounting bracket 11, the strap 13 can be rotated to be installed on the mask 10 according to actual needs.
[0027] Working principle: The threaded groove 3 and threaded sleeve 6 enable the connecting pipe 2 and connecting pipe 5 to be threadedly connected. When the connecting pipe 2 and connecting pipe 5 are threadedly connected, the sealing sleeve 8 rotates into the sealing groove 9 at one end of the outer sleeve 4, thereby sealing the gap between the connecting pipe 2 and connecting pipe 5, enhancing practicality. The soft pad 18 provides cushioning and protection for the user's hands. The friction-enhancing sleeve 16 increases the friction when the user holds the flute body 1. The Velcro 12 and mounting bracket 11 allow the strap 13 to be rotated to be mounted on the mask 10 as needed. In use, simply... Connect the connecting tube 2 to the connecting tube 5 as needed. At this time, the user wears the mask 10 fixed at one end of the connecting tube 5 and performs exhalation exercises. Through the setting of the flow sensor 14, the airflow speed and flow rate during the user's exhalation can be accurately measured. By continuously monitoring the exhalation flow data, after a period of lung flute training, it can be observed whether the exhalation flow has increased. The user's hand holds the lung flute body 1, and the user's four fingers are placed between the support 15 and the lung flute body 1. The pressure plate 17 is pressed down under the push of the spring 20, thereby limiting the user's hand and preventing the lung flute body 1 from accidentally falling due to the user's loose grip.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
