Description

  The present invention relates to blowback, and more particularly, to blowback that can be used for purposes such as health promotion, treatment, and beauty.

  Blowback has long been known as a blowback toy. In this blowback, a linear body having elasticity like a wire is disposed along the longitudinal direction of the cylindrical expansion body (bag-shaped portion), and one end of the cylindrical main tube is attached to one end of the expansion body. Connected to the other end of the special tube body is provided with a mouth blowing body through which the user blows air. When air is blown from the mouth blowing portion, the stretchable body is stretched, and in a state where air is not blown, the stretchable body is wound in a spiral shape by the elastic force of the linear body.

  Conventionally, such blowback has been mainly used as a toy for children, but blowback that can be used for breathing training for health promotion, treatment, beauty, and the like is known (for example, (See Patent Document 1). This blow-back is provided with a mouthpiece made of an antibacterial flexible material so that it can be detachably attached to the blow-in part, so that it can maintain good hygiene even after repeated use over a long period of time. It can be used for breathing exercises for the purpose of treatment, beauty, etc.

  For example, in the medical field, such breathing training is used for the prevention of childhood asthma, lung cancer patients, patients undergoing surgery, patients whose respiratory function is reduced by anesthesia before and after surgery, and environmental pollution such as PM2.5. This is performed for patients with respiratory dysfunction such as chronic obstructive pulmonary disease (COPD) caused by the above. In the nursing field, it is performed for prevention of aspiration during meals by the elderly or disabled persons or for swallowing rehabilitation. In the beauty field, this is done to prevent the formation of a frying line by training the muscles of the cheeks. In the music field, it is used for training of breathing and vocalization by vocalists. In the sports field, it is performed in order to increase the power of breathing, such as sport blowing arrows.

By the way, since such blowback is required to stretch the stretchable body first, a predetermined blowing force (required expiratory force) is required, but the stretchable body has been stretched by sufficiently blowing air into the stretchable body. When the state is reached, the telescopic body, the special tube body, and the mouth blowing body are filled with air, so that the necessary expiratory force required to maintain this state is not necessary. In other words, when air was blown in at the beginning, it could be maintained with a weak force. However, blowback used for the purpose of health promotion and treatment is important to blow in air for a certain period of time with a predetermined expiratory force, and such a purpose cannot be achieved by conventional blowback. there were.
Also, conventionally, if the expansion and contraction of the stretchable body is stopped and air blowing is stopped, the air remains in the stretchable body and remains stretched, and if the stretchable body is pulled by hand to correct this, There was a possibility that the elastic body was damaged.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a blowback that can blow in air for a predetermined time with a predetermined expiratory force and is not easily damaged even if the blowing is stopped and does not extend. .

In order to solve the above-mentioned problems, the invention of claim 1 includes a cylindrical exclusive tube, a cylindrical deformable elastic body provided at one end of the exclusive tube, and the other end of the cylindrical exclusive tube. A mouth blower that is connected to the side and blows air by the user, and when the user blows the mouth blower and blows the air, the stretchable body expands. The air hole that escapes the air inside the stretchable body to the outside is provided at a portion that is not wound spirally at the end of the stretchable body on the side of the specialized tube. Features.

According to a second aspect of the present invention, in the blowback according to the first aspect, the size and number of the air holes are set such that a predetermined amount of air escapes to the outside according to the purpose of use. To do.

A third aspect of the invention is characterized in that, in the blowback according to any one of the first and second aspects, the air hole is also provided in a free end portion of the stretchable body.

According to the first aspect of the present invention, the stretchable body is provided with an air hole through which air in the stretchable body is released to the outside. Therefore, this blowback requires the predetermined expiratory force required to stretch the expansion body for the first time, but because the air inside the expansion body escapes from the air hole to the outside, the expansion body is stretched In order to maintain the above, a predetermined necessary expiratory force is required. Thereby, since it becomes possible to blow in air for a fixed time with a predetermined expiration force, it is possible to provide blowback suitable for purposes such as health promotion and treatment.
In addition, since the air holes provided in the stretchable body are formed in portions that are not spirally wound at the end of the stretchable body on the side of the specialized tube, the air holes are not wound even if the stretchable body is wound spirally. It is possible to provide a blowback that is not closed and is not easily stretched even if the blowing is stopped, and is not easily damaged.

  According to the invention of claim 2, the size and number of the air holes are set so that a predetermined amount of air escapes to the outside according to the purpose of use. Therefore, it is possible to provide blow-back suitable for the purpose of use, such as respiratory treatment, swallowing rehabilitation, breathing and vocal training.

According to the invention of claim 3, in the case where a plurality of air holes are provided in order to release a predetermined amount of air according to the purpose of use to the outside, it is set so that the air escapes after the stretchable body reaches the most extended state. The air inside the stretchable body, the special tube body, and the mouth blowing body can be released to the outside more smoothly. For this purpose, by providing the air hole in the free end of the telescopic member, because in a state where elastics are most extended abuts the air pores are opened, can escape air from the air hole. Thereby, it becomes possible to provide the blowback suitable for the intended purpose.

  The present invention will be described below based on the illustrated embodiments.

(Embodiment 1)
1 to 3 show a blowback 1 according to Embodiment 1, FIG. 1 is a left side view showing the blowback 1, and FIG. 2 is a plan view showing the blowback 1 of FIG. FIG. 3 is a plan view showing a state in which the stretchable body 2 of the blowback 1 of FIG. 1 is extended. The blow-back 1 is a blow-back usable particularly for the purpose of promoting health, treatment, beauty, and the like, and mainly includes a stretchable body 2, a specialized tube 3, and a mouth blow body 4. The blowback 1 is set with a blowing force (necessary exhalation force) required to stretch the stretchable body 2 according to the purpose of use such as health promotion and treatment, the user situation, and the like.

  The stretchable body 2 is a tubular, deformable bag-like portion that swells when air is blown in, and is stretched by having a substantially circular cross section, and is wound in a spiral shape when air is not blown in. It is configured. The stretchable body 2 mainly includes a spiral portion 21, a linear body 22, a free end portion 23, a connection end portion (exclusive tube side end portion) 24, and an air hole 25.

  The spiral portion 21 is a portion wound in a spiral shape or a coil shape by blowing air, and is made of a paper material having a predetermined thickness, strength, density (weight per unit area), durability, and other materials (characteristics). It is comprised as a raw material, The outer diameter is set so that it may become a little larger than the internal diameter of the end of the exclusive tube 3. The length of the spiral portion 21 is set in accordance with the purpose of health promotion, treatment, beauty, etc. (use purpose of the blow-back 1), the user's oral function condition, user condition such as physical condition, and the like. . That is, the length of the spiral portion 21 is set so that the amount of air required to extend the spiral portion 21 becomes an appropriate amount of air set in advance according to the purpose and the user's situation.

  The linear body 22 is composed of a wire rod that is elastic and straightly arranged along the longitudinal direction of the spiral portion 21, for example, a stainless steel wire, and is sandwiched between paper materials of the spiral portion 21. . In a state where no external force is applied to the spiral portion 21 (a state where air is not blown into the expansion / contraction body 2), the spiral portion 21 is wound in a spiral shape / coil shape by the elastic force of the linear body 22, as shown in FIG. When an external force is applied to the spiral portion 21 (air is blown into the expansion / contraction body 2), as shown in FIG. 3, when the external force is released, the spiral portion 21 returns to a spiral shape when the external force is released. A force acts by the linear body 22. In other words, the elastic force of the linear body 22 is set so that the expiratory force required to stretch the expansion / contraction body 2 becomes an appropriate value set in accordance with the purpose of use of the blowback 1 or the user's situation. The elastic force is set to a predetermined value so that the stretchable body 2 does not stretch unless the necessary expiratory force for blowing air from the body 4 is not more than an appropriate value (predetermined value).

  As shown in FIG. 3, the free end 23 is a tip when the stretchable body 2 is extended. The free end portion 23 is a location where the stretchable body 2 formed in a bag shape is closed. The connection end portion 24 is an end portion on the opposite side to the free end portion 23 of the stretchable body 2, and is a connection portion with the special tube 3. The air hole 25 is a hole for letting the air blown into the expansion body 2, the exclusive pipe body 3, and the mouth blowing body 4 to the outside, and as shown in FIG. 3, the connection end 24 of the expansion body 2. One side, for example, is provided so as to penetrate the telescopic body 2 at a position where the spiral portion 21 does not become flat even if it is wound in a spiral shape.

  The reason why the air holes 25 are provided will be described. In the conventional blow-back, when the air is blown first for a long time, the expansion / contraction body is filled with air, so that the necessary exhalation force thereafter is not necessary. However, it is important to blow back air for a certain period of time with a predetermined expiratory force, specifically for the purpose of promoting health and treatment. Specifically, it is twice as long as the time required for breathing. It is considered effective to expel air over time and blow air back in. Therefore, by letting the air blown into the stretchable body 2 escape from the air hole 25, it is possible to blow air for a predetermined time with a predetermined expiratory force. This air hole 25 is set so that a predetermined amount of air escapes to the outside in accordance with the purpose of use and the user situation, such as respiratory treatment, swallowing rehabilitation, training of breathing method and vocalization method.

  In addition, when the blowing of air into the blowback 1 is stopped, the stretchable body 2 is wound in a spiral shape. However, if the air remains in the stretchable body 2, the stretchable body 2 is not wound in a spiral shape. If the air hole 25 is on the free end 23 side of the stretchable body 2, the air hole 25 may be blocked and air may not escape. Therefore, the air hole 25 is provided on the connection end 24 side, and the spiral portion 21 is provided at a position where it does not become flat even when wound in a spiral shape, thereby stopping the blowing of air into the blowback 1. Since the air in the expansion / contraction body 2 sometimes escapes from the air holes 25, the expansion / contraction body 2 is wound in a spiral shape. Thereby, the blowback 1 is prevented from being damaged and can be used for a long time.

  The special tube 3 is a portion where the user grips the blowback 1, and is a cylindrical body that is connected to the connection end 24 of the stretchable body 2 and is formed in a substantially cylindrical shape with a thick paper material having a predetermined material. . The exclusive tube 3 includes one end (exclusive tube end) 31 which is an end of the telescopic body 2 side and the other end (exclusive tube other end) 32 which is an end on the mouth blower 4 side. The one end portion 31 is inserted into the connection end portion 24 of the stretchable body 2 and connected with a vinyl tape or the like. The inner diameter and length of the special tube 3 are set so that the user can easily have the air and the air blower 4 can easily blow air into the stretchable body 2.

  The mouth blowing body 4 is a portion where the user blows air in addition to the mouth, and is substantially cylindrical and connected to the other end portion 32 of the main tube 3. The mouth blowing body 4 is formed of, for example, a plastic resin. For example, a mouthpiece for maintaining a good sanitary condition even when used repeatedly for a long period of time is provided on the mouth blowing body 4 so that the user's comfort is good.

  In the blowback 1 having the configuration shown in FIGS. 1 to 3, when the user blows air from the mouth blower 4, the air flows into the stretchable body 2, the stretchable body 2 extends, and the air is not blown. As shown in FIG. 1, the elastic body 2 is spirally wound back by the elastic force of the linear body 22. At this time, if the necessary exhalation force for blowing air from the mouth blowing body 4 is not equal to or more than an appropriate value (predetermined value) set in accordance with the purpose of use such as health promotion or treatment or the user's situation, the stretchable body 2 is stretched. Without being continued, the stretchable body 2 is configured not to extend to the maximum extent unless a predetermined amount of air is blown in accordance with the purpose of use such as health promotion and treatment, and the user's situation. Furthermore, even if the expansion / contraction body 2 is in the extended state, air escapes from the air holes 25. Therefore, in order to maintain the extended state of the expansion / contraction body 2 to the maximum extent, the purpose and user of health promotion, treatment, etc. It is configured such that air can be blown for a certain period of time with a preset exhalation force according to the situation or the like. Therefore, by repeating the expansion and contraction (blowback) of the expansion / contraction body 2 using such a blowback 1, exercise and training with appropriate expiratory force suitable for the purpose and the user situation can be performed. .

  As described above, according to the blowback 1, the air hole 25 is provided on the connection end portion 24 side at a position where the spiral portion 21 does not become flat even when the spiral portion 21 is wound in a spiral shape. Therefore, when the user blows air from the mouth blower 4, the blowback 1 is in a state where the air flows into the stretchable body 2 and the stretchable body 2 is extended, and the air escapes from the air hole 25. In order to maintain the body 2 extended to the maximum extent, it is necessary to blow in air for a certain period of time with an expiratory force set in advance according to the purpose of use such as health promotion and treatment, and the user's situation. Thereby, since it becomes possible to blow in air for a predetermined time with a predetermined expiration force, it is possible to provide the blow-back 1 suitable for the purpose of health promotion or treatment. Further, the air hole 25 is set so that a predetermined amount of air escapes to the outside according to the purpose of use and the user situation, such as respiratory treatment, swallowing rehabilitation, training of breathing method and vocalization method. Therefore, it is possible to provide blowback suitable for the purpose of use.

  Further, according to the blowback 1, since the air holes 25 are provided, the air in the stretchable body 2 escapes from the air holes 25 when the blowing of air into the blowback 1 is stopped. The body 2 is wound in a spiral shape. Thereby, the blowback 1 is prevented from being damaged and can be used for a long time.
