  However, since the conventional apparatus described in Document 1 or Document 2 performs suction of sputum, there is a risk associated with breathing. It is desirable to use it under the control of qualified medical personnel, and there has been concern about use by family members and caregivers. Also, handling was troublesome. For these reasons, although it should be done frequently, it was not easy to use. In addition, for example, there is a demand for simple use such as sitting in a chair or resting in a bed at a hospital, home, or the like.

  The device described in Document 3 promotes excretion by vibrating the subject's lungs and bronchi, and does not involve sputum suction. However, the act of energizing a patient with a low-frequency current is uneasy for easy use at home.

  In view of the above problems, an object of the present invention is to provide a rejection promoting device that can be used more safely and easily.

In order to achieve such an object, the present invention is a three-dimensional network structure having a spring structure composed of continuous filaments that are randomly entangled in a loop shape and partially heat-welded.

The bulk density of the continuous filament in a three-dimensional network structure is preferably ^{0.03~0.4g / cm 3, 0.06~0.15g / cm} 3 is more preferable. When the density of the continuous filaments in the three-dimensional network structure is expressed by the porosity, it is preferably 60 to 97%, more preferably 85 to 94%.

This bulk density may be uniform, but hard and soft may be separated. For example, the surface layer may be a hard part, and the region inside the surface layer may be a soft part. In this case, the bulk density of the surface layer (hard portion) is preferably from 0.1 to 0.6 g / cm ^3, more preferably 0.2-0.4 g / cm ^3. The porosity of the surface layer is preferably 40 to 90%, more preferably 60 to 80%. The bulk density of the inner layer (soft) is preferably ^{0.01~0.85g / cm 3, 0.04~0.2g / cm} 3 is more preferable. The porosity of the inner layer is preferably 15 to 99%, more preferably 80 to 96%.

  The vibrator is installed so that the vibration is transmitted to the subject over a wide range. Although it is desirable to install the vibrator from the bottom so that vibration propagates, this is not restrictive. Further, the vibrator to be provided may be embedded in a three-dimensional network structure so as not to be visible from the outside, or may be exposed to the outside. The exposure here includes both a state in which the vibrator protrudes to the outside and a state in which the vibrator does not protrude. The internal location of the external vibrator can also be set as appropriate. The number of the vibrators to be installed may be singular or plural. In the case where a plurality of vibrators are installed, the vibrators are arranged so as to cover a wide range.

  The present invention, unlike a conventional evacuation device, promotes evacuation by giving vibration directly to the subject. According to the exclusion promoting device of the present invention, it is possible to transmit the diffused vibration to the subject. Thereby, the sputum clogged in the bronchus is cut and comes out of the throat naturally, or the sputum naturally flows into the stomach through the esophagus, thereby having an effect of facilitating the expulsion easily. Since it is not accompanied by suction by a suction machine, it can be used safely. In addition, since it is an easy-to-handle device, it can be used easily even by the target person's family, caregiver, or even the person himself.

It is a perspective view (the 1) of the exclusion promotion apparatus 1. It is a perspective view (the 2) of the exclusion promotion apparatus 1. It is a perspective view of the vibrator of the exclusion facilitating device 1. It is a figure which shows the image which image | photographed the structure | tissue of the surface layer of the three-dimensional network structure of the exclusion promotion apparatus 1. FIG.

  Hereinafter, the exclusion facilitating device 1 of the embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the exclusion facilitating device 1 has a vibrator 3 provided in a three-dimensional network structure 2. This is a structure in which the vibration of the vibrator 3 is transmitted to the outside through the elastic three-dimensional network structure 2.

  The three-dimensional network structure 2 is a network structure including a plurality of continuous filaments formed in a random loop shape and in contact with each other and having a predetermined bulk density (see FIG. 4). ). The continuous filaments are entangled in a loop shape by extrusion and are partially heat-sealed to form a spring structure.

  The overall shape of the three-dimensional network structure 2 is a shape that expands to an area that can be applied to the corresponding back or chest so as to impart vibration to the lungs with a constant thickness dimension. The three-dimensional network structure 2 according to the present embodiment has a flat bottom surface, two convex portions and one concave portion are formed between the top surfaces, and the contact area with the human body becomes two convex portions. Is formed. The shape is not limited to this, and an appropriate shape may be used as long as the function can be exhibited.

  Examples of the dimensions of the three-dimensional network structure 2 include a length of 100 mm to 300 mm, a width of 100 mm to 300 mm, and a thickness of 30 mm to 150 mm, but are not limited thereto. The dimensions of the three-dimensional network structure 2 can be arbitrarily formed by fusing, mechanical cutting, hot pressing, or the like according to the use such as infants, elderly people, and adults.

  The three-dimensional network structure 2 has a laminated structure including an inner layer in which the bulk density of the network structure is set low and a surface layer (hard part) in which the bulk density is set higher than that of the inner layer. The surface of the surface layer constitutes a contact surface that contacts the human body. FIG. 4 shows the structure of the three-dimensional network structure 2. The vibrator 3 is arranged so that the lamination direction of the laminated structure is orthogonal to the direction from the vibrator toward the human body. Furthermore, the said surface layer is arrange | positioned at the front and back both surfaces of the said inner layer.

  The contact surface is not limited to the one that actually contacts the human body, and may be used by covering the contact surface with a cover such as a cloth, so that the contact surface directly contacts the human body. May be used. However, it is preferable to avoid the cover that absorbs the vibration of the three-dimensional network structure.

  The three-dimensional network structure 2 uses a thermoplastic resin as a raw material or a main raw material. For example, as a thermoplastic resin, a polyolefin resin such as polyethylene (PE) or polypropylene (PP), a polyester such as polyethylene terephthalate, a polyamide such as nylon 66, a vinyl chloride resin such as polyvinyl chloride, or a styrene resin such as polystyrene. Is mentioned. Moreover, the copolymer and elastomer copolymerized based on the said resin, what blended the said resin, etc. are mentioned. For example, a vinyl acetate resin and a polyethylene resin mixed with rubber are suitable. Moreover, flakes such as PET bottles or chips may be used. A PET bottle can be pulverized as it is and melted to form a flake. A virgin resin or the like can be applied to a thermoplastic resin other than the recycled one.

  Further, the thermoplastic resin may be a mixture of vinyl acetate resin (hereinafter referred to as VAC), ethylene vinyl acetate copolymer (hereinafter referred to as EVA), styrene butadiene styrene (hereinafter referred to as SBS), or the like. For example, a material obtained by mixing a polyolefin resin with a vinyl acetate resin, an ethylene vinyl acetate copolymer, or styrene butadiene styrene may be used as a raw material. It is good also considering the mixture (for example, thermoplastic elastomer) of polyolefin resin, such as PE and PP, and VAC, EVA, or SBS as a raw material.

  The grooves 2a are formed by cutting the three-dimensional network structure 2 with a cutter. The groove 2a does not necessarily have to be perpendicular to the three-dimensional network structure 2, and the angle may be changed according to the application and the number of grooves 2a is arbitrary.

  The vibrator 3 is also called a vibrator and vibrates, and a method of generating vibration by attaching and rotating a weight with a biased center of gravity on a motor shaft is generally used. Here, as shown in FIGS. 1 to 3, the vibrator 3 is fixed with a cylindrical case 3a, a pair of motors 3b fixed to both ends of the cylindrical case 3a, and a rotating shaft 3c of the motor 3b with an eccentric center. A half-moon shaped eccentric plate 3d and a wiring 3e connected to the motor 3b are provided. The vibrator 3 is fitted into the notched groove 2 a of the three-dimensional network structure 2. The cylindrical case 3a is transparent. Vibration generated by the eccentric rotation of the eccentric plate 3d is propagated to the three-dimensional network structure 2 via the cylindrical case 3a.

  Next, a method for manufacturing the rejection accelerating device 1 will be described. First, a method for manufacturing the three-dimensional network structure 2 will be described. In a loop molding apparatus, a polyolefin resin such as PE or PP introduced from a hopper is melted and kneaded at a predetermined temperature, and predetermined from a large number of nozzles having a predetermined diameter provided in a molding die (mold) of an extrusion molding machine. A continuous filament of molten thermoplastic resin is extruded at an extrusion speed of. The moving speed of the roll or belt of the take-up machine is set slower than the extrusion speed, the upper part of the take-up machine protrudes from the water surface, and the other part of the take-up machine is submerged. The continuous filament is taken up by this take-up machine.

  In this way, the continuous filaments are randomly formed in a loop shape, and the loops are partially entangled and welded. When this continuous filament is solidified in water and taken out by a winding roll, it becomes a filament aggregate.

  A three-dimensional network structure 2 is obtained by cutting the taken-out filament aggregate into a suitable length by a cutting device.

  In the loop forming apparatus, before the continuous filament touches the water surface of the water tank, the third layer that increases the density of the surface layer by narrowing the thickness of the portion that becomes the outer peripheral side surface of the filament assembly to increase the bulk density. The original network structure 2 can be obtained. Further, before the continuous filaments touch the endless belt or the take-up roll of the conveyor, the surface thereof can be cooled and solidified so that the belt bite does not stick to the product. In order to make the fusion between the loops uniform, it is desirable to form the loops smoothly.

  When a continuous filament having a loop formed in water is taken up by a take-up machine, the three-dimensional network characteristics may be changed by changing the speed of the take-up machine.

  Next, a notch is formed in the three-dimensional network structure 2 to form a groove 2a, and the vibrator 3 is fixed in the groove 2a, whereby the evacuation promoting device 1 is completed.

  Since the ability to cut the heel is influenced by the frequency, amplitude, vibration strength, density of the three-dimensional network structure, and the like of the vibration generated by the vibrator 3, a proper range of physical properties is set.

  The usage method of the exclusion promoting apparatus 1 is demonstrated. First, two convex portions are brought into contact with the subject's back, and then the power is turned on to vibrate the vibrator 3. This can promote excretion simply by hitting the back. It can also be used against the chest side.

  The exclusion promoting apparatus 1 of the embodiment of the present invention is not on the development extension of the conventional exclusion promoting apparatus, but has a different form and configuration. Therefore, the elimination facilitating apparatus according to the present invention can create an unprecedented new feeling (feeling that the lungs are shaken). Specifically, there is an effect that vibration generated by the vibrator 3 is effectively diffused over the entire surface of the human chest or back through the three-dimensional network structure 2. Therefore, the vibration caused by the vibrator effectively cuts the sputum clogged in the bronchus and drains it naturally from the throat, or the sputum cut by vibration flows from the bronchus through the esophagus to the stomach, so the symptoms are alleviated Is done. The squeezing promotion device 1 is safe to use because it does not involve soaking of soot, and is easy to handle because of its structure. This eliminates the need to use a sputum suction device or reduces the number of uses. Even if a suction device is used in combination for the convenience of the subject, it is effective because it will improve the cutting ability.

  The present invention is not limited to the above-described embodiments, and improvements, changes, additions, and the like can be added without departing from the technical idea of the present invention. Such modifications and equivalents are also included in the technical scope of the present invention.

  The exclusion promoting apparatus of the present invention can be widely used at home, hospitals and the like.
