Description

[0001]
[Industrial application fields]
The present invention relates to an improvement of a chest wall vibration stimulation (hereinafter referred to as CWV) device, and an object of the present invention is to provide a CWV device that can be used easily and can save labor. .
[0002]
[Prior art]
The CWV device uses mechanical vibration of a steep waveform (triangular wave, exponentially increasing wave, etc.) having a vibration frequency of about 50 to 100 Hz, and synchronizes with breathing, and inspiratory muscles (second to third) The intercostal muscle) is a respiratory conditioning device that controls the respiratory muscles by stimulating the expiratory muscles (seventh to ninth intercostal muscles) at the time of expiration, and is used for the purpose of eliminating the difficulty of breathing caused by asthma attacks.
[0003]
The respiratory motion is caused by moving the respiratory muscles according to the central command, but when the phase of the central command and the respiratory motion is shifted due to an asthma attack or the like, breathing difficulty occurs. When CWV stimulation is performed at this time, the muscle spindle of the respiratory muscles is excited and this signal is transmitted to the center, and the signal from the muscle spindle and the central respiratory command are synchronized at the center, thereby eliminating the difficulty in breathing.
[0004]
There are several prior inventions related to CWV. For example, Japanese Patent Laid-Open No. 60-168465 is intended to eliminate asphyxia by suppressing a asthma attack by attaching a vibrating body to a predetermined site with a band or the like and performing CWV stimulation. Japanese Examined Patent Publication No. 61-10145 generates vibration with a speaker and transmits it to the chest wall via an air duct to perform CWV stimulation.
[0005]
On the other hand, Japanese Utility Model Laid-Open No. 58-185224 embeds a vibrating body in a bed and applies the same mechanical vibration as described above. There is also an invention to which CWV is applied. For example, in Japanese Utility Model Publication No. 63-48279, a CWV vibrator is incorporated into a bed to promote sleep falling. There are also several related applications for these.
[0006]
Basically, CWV stimulation is synchronized with breathing and stimulates the inspiratory muscle during inspiration and the exhaled muscle during exhalation with a specific mechanical vibration. However, in respiratory conditioning, it is often necessary to assist only inspiration or only in expiration, and inspiratory phase CWV stimulation that provides stimulation only during inspiration and expiratory phase CWV stimulation that provides stimulation only during expiration is also performed. It is.
[0007]
[Problems to be solved by the invention]
Eliminating breathlessness is important in improving the quality of life (QOL) of patients, and the significance of the CWV device is great. However, in Japanese Patent Laid-Open No. 60-168465, the vibrating body must be fixed at a predetermined position by a band or the like, and in Japanese Patent Publication No. 61-10145, a dedicated ring-shaped vibrating body must be wound around the chest and fixed. There is a problem in terms of medical efficiency due to the troublesomeness of wearing.
[0008]
On the other hand, Japanese Utility Model Publication No. 58-185224 gives vibration with a vibrating body embedded in the bed and can be stimulated only by getting on the bed. However, since the patient's weight is applied, sufficient stimulation can be obtained. There is a problem that the body must be shifted and aligned to stimulate a predetermined position. As described above, the CWV stimulating device has the features that it can effectively eliminate breathlessness and has no side effects, but there is no simple device that can be used easily.
[0009]

[0011]
【Example】
FIG. 1 shows an embodiment of the invention according to claim 1, which is an embodiment of a chair-type contact-type CWV device. In the figure, reference numeral 1 is an inspiratory muscle stimulation vibrator for stimulating the inspiratory muscle, 2 is an exhalation muscle stimulation vibrator for stimulating the exhalation muscle, 3 is a control unit, 4 is a respiration sensor, 5 is a face pad, 6 is a chest pad, 7 is an armrest, and 8 is a seat.
[0012]
The inspiratory muscle stimulating vibrator 1 and the exhaled muscle stimulating vibrator 2 have a steep waveform (triangular wave or exponential) with a frequency of about 50 to 100 Hz for performing CWV stimulation as described above. Generates mechanical vibrations such as functionally increasing waves. This is arranged in the contact portion with a distance between the breath muscles and the breath muscles of a person with a standard physique. The interval between the inspiratory muscle stimulation vibrator 1 and the exhalation muscle stimulation vibrator 2 can be adjusted according to the physique .
The control unit 3 discriminates expiration and inspiration from the signal of the respiration sensor 4 and vibrates the inspiratory muscle stimulation vibrator 1 during inspiration and the exhalation muscle stimulation vibrator 2 during expiration.
As the stimulation vibration, a specific vibration having a sharp rising waveform (such as a triangular wave or an exponentially increasing wave) having a frequency of about 50 to 100 Hz is used. However, mechanical vibration stimulation conditions (vibration waveform, vibration frequency, amplitude, treatment time, etc.) can be changed from the operation unit (not shown) of the apparatus.
[0013]
The respiration sensor 4 detects respiration. In this example, a hood for collecting respiratory airflow is provided at the opening of the face pad 5 provided on the chair, and a respiratory flow meter is connected for use. Since the respiration sensor 4 only needs to detect respiration, any sensor may be used and the installation method is not limited.
[0014]
The face pad 5 leans against the face during treatment, and an opening is provided in a portion where the nose and mouth come. If you put your face on it, you can breathe easily and support the weight of your head, so you can relax. As described above, in the present embodiment, the hood for collecting respiratory air is provided at the opening and the respiratory sensor 4 is provided. Therefore, it is possible to measure respiration simply by leaning on the device and breathing. The chest pad 6 supports the chest when leaning against the device. The arm rest 7 supports the arm during the treatment. Seat 8 is the seat on which the patient sits during the treatment and is tilted slightly forward so that the patient can relax and lean towards the device.
[0015]
The arrangement of the face pad 5, the inspiratory muscle stimulating vibrator 1 and the expiratory muscle stimulating vibrator 2 is set in accordance with the interval between the inspiratory muscle and the expiratory muscle of a standard physique. When sitting on a chair and placing a face on the opening of the face pad 5, the inspiratory muscle stimulating vibrator 1 is inhaled and the exhaled muscle stimulating vibrator 2 is in the exhaled muscle. The shape and dimensions are designed to touch. As described above, since the respiratory muscles are widened, they may stimulate a somewhat wide range, so that most people simply vibrate and touch their face to the opening of the face pad 5 to vibrate. The body can be brought into substantially contact with a predetermined stimulation site. When the position of the vibrating body does not match the predetermined stimulation site, the position of the vibrating body is adjusted and used.

If the height of the seat or the contact position of the vibrating body is shifted, adjust it. However, if the person has a standard physique, the vibrating body comes into contact with a predetermined respiratory muscle without making these adjustments, so that stimulation can be started as it is.
[0017]
When the stimulation conditions are set and the treatment is started, the inspiratory muscle stimulating vibrator 1 is vibrated during inspiration and the exhaled muscle stimulating vibrator 2 is vibrated during inspiration to synchronize with breathing. Stimulate under the following stimulation conditions. Usually, the treatment conditions do not need to be changed so much and may be fixed.
[0018]
Thus, when the invention according to claim 1 is used, most people can perform CWV stimulation only by sitting on the seat and leaning on the apparatus.
In this embodiment, the abutment portion can be brought into contact with the stimulation site only by sitting and leaning on the device, and vibration stimulation can be performed in synchronization with breathing. Such a shape may be used, and it is not always necessary to use it.
[0019]

After sitting on the seat 8 and adjusting the height of the contact part and positioning the vibrating body, input stimulation conditions, lean against the device, face on the face pad 5, and chest wall on the vibrating part. When treatment is started by applying this, respiration is detected by the respiration sensor 4, and the vibrating body 1 is vibrated only during inspiration to perform predetermined mechanical vibration stimulation.
[0021]
Any example of this, face pad 5, the chest pad 6, the arm rests 7 may be of any shape, because it is not always necessary, may not be used. Although not shown, the vibrator 1 for stimulating the inspiratory muscles can be omitted from FIG. 1, and an expiratory gas phase CWV device for CWV stimulation of the exhaled muscles only during expiration can be realized.
[0022]
FIG. 3 is an example of a stand-like contact-type respiratory conditioning device according to the invention of claim 1, in which a person who receives vibration stimulation is treated in a standing position and leaning on the device. . 1 and 2 are an inspiratory muscle stimulation vibrator and an exhalation muscle stimulation vibrator, 3 is a control unit, 4 is a respiration sensor, 5 is a face pad, 6 is a chest pad, 7 is an armrest, and 9 is a stand. is there. The shape, dimensions, and usage of each part are the same as in the embodiment of FIG.
