Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breathing training, in particular to a human breathing training device. Background Art
[0002] Some projects in the hospital require radiological examinations or treatments, which require the patient to cooperate with breathing. For example, during chest DR photography, the doctor gives the patient a command to hold his breath (hold it, maintain a state of apnea, and keep the lungs full and still). When the patient holds his breath, the imaging shutter is pressed. At this time, the respiratory muscles stop moving and the lungs are relatively still, which can avoid imaging blur caused by lung movement, so that the largest chest X-ray field of view can be obtained. During spiral CT examinations, the CT machine will also issue similar commands to the patient so that the CT film can image a larger chest field of view.
[0003] However, special groups such as children, deaf-mute people, and Alzheimer's patients are unable to respond to the doctor's breathing instructions, and the images can only be taken randomly (blindly). This results in poor image quality and cannot be used for clinical diagnosis. In severe cases, the images need to be retaken, which brings a series of problems, such as repetitive work for doctors, multiple uses of equipment, and low equipment utilization, which causes patients to be exposed to radiation once more.
[0004] In response to the above problems, Chinese patent document CN116019421A discloses a breathing prompt system, method and device, which include a mask, a catheter, a sensor, a controller, a communication module and a prompt module. The mask covers the user's respiratory organs, and the sensor detects the physical quantity of the detection factor in the respiratory channel that changes with the respiratory state and generates a corresponding electrical signal. The communication module is used to transmit the electrical signal to the controller. After receiving the electrical signal, the controller reads the data fed back by the sensor, and runs the respiratory state detection control program and algorithm to determine the respiratory state and issue a prompt instruction. At the same time, the communication module is used to transmit the electrical signal of the prompt instruction to the prompt module. After receiving the electrical signal transmitted by the controller, the prompt module reads the prompt instruction and displays the user's current respiratory state according to the prompt instruction, so that the user's current respiratory state can be clearly observed, so that corresponding measures can be taken according to the user's respiratory state.
[0005] Since the above patent structure is complex and requires a series of algorithms to cooperate, the overall structure of the breathing prompt device is complex and the cost is high, which increases the cost of repair or replacement after damage. Utility Model Content

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.
[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0028] Reference Figures 1 to 5 As shown, a human breathing training instrument includes a mask body 1, an exhaust pipe 11 is provided at the front end of the mask body 1, and a shrapnel group 2 is provided inside the exhaust pipe 11; it also includes an inhalation sensor 3 and an exhalation sensor 4, the inhalation sensor 3 is arranged inside the exhaust pipe 11 and is located on the side of the shrapnel group 2 close to the mask body 1, and the exhalation sensor 4 is arranged inside the exhaust pipe 11 and is located on the side of the shrapnel group 2 away from the mask body 1; it also includes a signal generator, and the signal generator is electrically connected to the inhalation sensor 3 and the exhalation sensor 4.
[0029] The user buries the oral cavity and nasal cavity in the mask body 1, so that the airflow of the user's inhalation and exhalation can only be discharged through the exhaust pipe 11. When the user inhales, exhales or holds his breath, the spring group 2 will be driven to move in different states.
[0030] When the user inhales, air enters the exhaust pipe 11 from the outside of the exhaust pipe 11, thereby driving the spring group 2 to move. When the spring group 2 moves and is recognized by the inhalation sensor 3, the signal generator sends an inhalation signal, indicating that the user is in an inhalation state.
[0031] When the user exhales, air is discharged from the exhaust pipe 11 to the outside, thereby driving the spring group 2 to move. When the spring group 2 moves and is recognized by the exhalation sensor 4, the signal generator sends an exhaust signal, indicating that the user is in the exhalation state.
[0032] When the user does not inhale or exhale, it indicates that the user is in a breath-holding state, so the inhalation sensor 3 and the exhalation sensor 4 do not work, and the signal generator sends a breath-holding signal, indicating that the user is in a breath-holding state.
[0033] In order to ensure the detection sensitivity of the human breathing training device of the utility model, it is necessary to ensure that the spring piece can swing due to the airflow of the user's inhalation and exhalation, so the spring piece is preferably a plastic card. In another embodiment, the spring piece can be composed of an airtight film plus a connecting structure that is rotatably connected to the exhaust pipe 11, and the connecting structure must have a reset structure when inhaled and exhaled, and the reset structure can be composed of a spring with relatively small elastic force, and the connecting structure can be composed of a light-weight plastic or carbon bracket 5 structure.
[0034] The signal generator can remind the doctor and the user that the user is currently in the inhalation state, exhalation state or breath holding state through different light colors, sounds or a combination of sound and light.
[0035] When the spring piece is made of plastic card, the property of the plastic card itself to reset after deformation can be utilized, so that when not inhaling or exhaling, the spring piece remains in a vertical state, that is, the user is in a breath-holding state. The utility model provides two embodiments of the spring piece group 2 and the connection between the spring piece group 2 and the exhaust pipe 11.
[0036] In the first embodiment, referring to Figure 2 and Figure 3 As shown, the device further includes a bracket 5, which is fixed to the exhaust pipe 11. The bracket 5 is provided with a plurality of air holes 51. The spring group 2 includes a first spring 21 and a second spring 22. One end of the first spring 21 and the second spring 22 is fixed to the bracket 5 by gluing or other methods. When the user exhales, the airflow passes through the air holes 51 and drives the free end of the first spring 21 to move toward the exhalation sensor 4 and is recognized by it; when the user inhales, the airflow passes through the air holes 51 and drives the free end of the second spring 22 to move toward the inhalation sensor 3 and is recognized by it.
[0037] The first spring piece 21 and the second spring piece 22 are close to one end of the exhaust pipe 11, and a ventilating slit 23 is provided between the exhaust pipe 11 and the closure. The airflow can accelerate the flow speed through the ventilating slit 23, so that the first spring piece 21 and the second spring piece 22 can be driven to move more easily, thereby improving the detection sensitivity of the human breathing training device of the utility model. In addition, the first spring piece 21 and the second spring piece 22 only move in one direction, which can reduce the fatigue damage caused by the reciprocating motion of the first spring piece 21 and the second spring piece 22, and improve the service life.
[0038] In this embodiment, the cross section of the exhaust pipe 11 is a rectangular or circular structure, so as to facilitate the installation of the bracket 5 and the exhaust pipe 11 .
[0039] In the second embodiment, the difference between the second embodiment and the first embodiment is that the second embodiment does not need to use the bracket 5, which can save costs. Figure 4 and Figure 5 As shown, the spring piece group 2 includes a first spring piece 21 and a second spring piece 22, which are fixed to the exhaust pipe 11, and a ventilation slit 23 is provided between the first spring piece 21 and the second spring piece 22. When the user exhales, the airflow passes through the ventilation slit 23 and drives the free ends of the first spring piece 21 and the second spring piece 22 to move toward the exhalation sensor 4 and be recognized by it; when the user inhales, the airflow passes through the ventilation slit 23 and drives the free ends of the first spring piece 21 and the second spring piece 22 to move toward the inhalation sensor 3 and be recognized by it.
[0040] In order to achieve the connection between the first spring clip 21 and the second spring clip 22 and the exhaust pipe 11, both ends of the first spring clip 21 and the second spring clip 22 extend toward both sides to form a limiting portion 211, and a baffle is sandwiched between the limiting portion 211 and the exhaust pipe 11. In this embodiment, the exhaust pipe 11 adopts a rectangular cross-section structure, which facilitates the installation of the first spring clip 21 and the second spring clip 22.
[0041] The distance between the inhalation sensor 3 and the exhalation sensor 4 and the shrapnel group 2 is an important parameter affecting the detection sensitivity of the human breathing training device of the present invention. If the distance between the inhalation sensor 3 and the exhalation sensor 4 and the shrapnel group 2 is too small, the shrapnel group 2 itself will be slightly shaken and recognized by the inhalation sensor 3 and the exhalation sensor 4, and an error signal will be sent. If the distance between the inhalation sensor 3 and the exhalation sensor 4 and the shrapnel group 2 is too large, the user needs to use a lot of force to blow the shrapnel group 2, which is not conducive to use. Therefore, as a preferred embodiment, the distance between the inhalation sensor 3 and the exhalation sensor 4 and the shrapnel group 2 is 3mm-7mm.
[0042] The inhalation sensor 3 and the exhalation sensor 4 include but are not limited to a contact switch sensor, an airflow sensor, an infrared sensor, an oxygen concentration sensor, a carbon dioxide concentration sensor, etc. Preferably, the inhalation sensor 3 and the exhalation sensor 4 use an infrared sensor or an airflow sensor to ensure the sensitivity of identifying the spring sheet group 2, and can more accurately determine whether the user is in a breath-holding state.
[0043] A strap 12 is fixedly provided at the rear end of the mask body 1 , and the mask body 1 can be firmly fixed to the user's face through the strap 12 .
[0044] As an extended solution, the number of the spring piece group 2 is not limited to the first spring piece 21 and the second spring piece 22 , and the number of the spring pieces can be multiple.
[0045] As an extended solution, a signal indicator is provided inside the mask body 1. The signal indicator can be an electronic display screen, and the doctor controls the electronic display screen to display the user's inhalation action, exhalation action, or breath-holding action, and the user can observe the display content of the electronic display screen and perform corresponding actions according to the doctor's instructions.
[0046] When in use, the user buries both the oral cavity and the nasal cavity in the mask body 1, so that the airflow of the user's inhalation and exhalation can only be discharged through the exhaust pipe 11. When the user inhales, exhales or holds his breath, the spring group 2 will be driven to move in different states, and then the signal sent by the signal generator is used to determine whether the user is in the inhalation, exhalation or breath holding state. When using the human breathing training device of the utility model, each patient can avoid cross infection by replacing a sterile set cup of the appropriate size in the mask body 1 or wiping and disinfecting the mask body 1 with a sterile cotton before use.
[0047] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
