Description

  The present invention relates to a water bed type massage machine.

In a conventional water bed type massage machine, a jetting liquid is jetted from a nozzle provided in a main body housing toward an upper membrane member to give a massage effect to a patient on the membrane member (for example, Patent Document 1). reference).
JP 2000-325420 A

  In this massage machine, since the distance between the membrane member and the nozzle is large, the pressure loss of the ejected liquid ejected from the nozzle is large, and because the thickness of the membrane member is large, the loss of energy transmission is large and is given to the patient. Reduced massage effect. Therefore, it is necessary to increase the performance of the liquid supply pump. Moreover, since the main body housing is large (high), a large space is required for the installation location. Furthermore, since the massage effect is given to the whole body of the patient while moving the nozzle, it is difficult to provide a massage effect by quickly responding only to the part requiring the body massage.

In addition, a union joint 32 having a liquid flow path and inserted into the branch pipe 18 is attached to the lower part of the cylindrical fixing tool 24.

  On the upper surface of the nozzle head 39, an ejection hole 23 for ejecting the liquid L upward from the horizontal plane at an inclination angle α (30 ° ≦ α ≦ 80 °) is provided at a position separated from the vertical axis 45 by a distance R. . A cylindrical water guide pipe 29 having an ejection hole 23 at one end 51 is bent in an S shape inside the nozzle head 39 so as to pass through the vertical axis 45 on the lower surface of the nozzle head 39. . The other end side 21 of the water conduit 29 protrudes downward from the lower surface of the nozzle head 39 with the vertical axis 45 as the axis, and can rotate around the vertical axis 45 in the hole 42 of the cylindrical bearing 40. It is inserted. The other end 21 is provided with a retaining washer 30 for preventing it from coming into sliding contact with the lower end surface 41 of the cylindrical bearing 40.

10, 11, and 12, the second ejection nozzle 8 b having a large rotational speed is composed of a short circular cylindrical portion 36 and an upward liquid flow 50 projecting from the outer peripheral surface of the small circular portion 36. , A cylindrical rotating shaft 44 that protrudes from the lower surface of the small disk portion 36 and has a flow path 49, and a bearing 37 that rotatably holds the rotating shaft 44 on the inner peripheral surface. A cylindrical fixing tool 46 having a horizontal flange portion 47 and a nut 25 disposed in a through hole of the mattress receiver 6, and a peripheral portion of the hole portion provided in the lower wall portion 14 of the mattress 7, The packing 9 is sandwiched between the nut 25 and the horizontal flange 47 of the fixing tool 46. Further, the bearing 37 is held in the cylindrical fixing device 46 by a retaining ring 52, and by removing the retaining ring 52, the small disk portion 36 and the bearing 37 can be replaced in accordance with the application and the model. . The blades 43 have a flat plate shape and project in an inclined manner so that the lower side is forward with respect to the rotation direction. H ₈ is the nozzle height from the lower wall portion 14 to the upper surface of the small disk portion 36. In addition, a union joint 32 having a liquid channel and inserted into the branch pipe 18 is attached to the lower part of the fixing tool.

  On the upper surface of the small disk portion 36, an ejection hole 23 for ejecting the liquid L upward from the horizontal plane at an inclination angle α (30 ° ≦ α ≦ 70 °) is provided at a position separated from the vertical axis 45 by a distance R. Yes. The rotating shaft 44 is formed with an eccentric channel hole 48 having a center that is eccentric with the vertical axis 45 and an eccentric distance e above the channel 49. Inside the small disk portion 36, A flow path 33 is formed between the eccentric flow path hole 48 and the ejection hole 23. Here, the blade 43 is attached to a point symmetrical with the ejection hole 23 with respect to the vertical axis 45 (as shown).

  As shown in FIGS. 1 to 3, the patient 4 lies on the mattress 7 of the water bed 5 as described above, and when the circulation pump 10 is operated, the liquid L passes through the plurality of branch pipes 18 and the ejection nozzles 8. The jet nozzle 8 jets the liquid L in the mattress 7 while rotating the upper part as shown by the arrow 35. This jet liquid flow gives a jet liquid pressure stimulus below the upper wall 13 in the mattress 7, and each part of the body of the patient 4 has a different massage (stimulation) effect (as shown in FIG. 6). Receive. The jet liquid flow of the first jet nozzle 8a corresponding to the shoulder and back of the patient 4 is jetted from the second jet nozzle 8b corresponding to the left and right sides of the other patient's neck, lower back, thigh and lower limbs. Compared to liquid flow, it provides a low-frequency massage effect associated with low-speed rotation. Without being limited to the above-described arrangement, the first ejection nozzles 8a that give a low-frequency massage effect may be arranged corresponding to the left and right sides of the patient's neck, lower back, thigh, and lower limbs.

  The patient 4 adjusts the flow rate by increasing / decreasing the number of rotations of the circulation pump 10 with a controller (not shown) in order to change the intensity of the massage effect received. A doctor, nurse, or attendant (or patient 4) sends a control signal from a controller (not shown) to the switching valve 26, and electrically opens and closes by ON-OFF switching, thereby allowing each part of the body to open and close. Individual adjustments are made to the jet nozzle 8 that jets to the nozzle. Further, the circulation pump 10 circulates the liquid whose temperature is adjusted by the temperature controller 19 through the pipe 27, and the liquid in the mattress 7 is always kept at an appropriate temperature.

In the first ejection nozzle 8a shown in FIGS. 7 to 9, the liquid L having the ejection force F is ejected from the ejection hole 23 through the pipe 18 through the union joint 32, the fixing tool 24, and the water conduit 29. Then, the nozzle head 39 rotates as indicated by an arrow 35 by the component force F _{1 in} the radial direction of the liquid L. This rotational moment (the magnitude of the rotational force) is the product of the component force F ₁ and the distance R. Further, the component force F _{2 in} the vertical direction of the liquid L is a pushing force (massage pressure) that hits the upper wall portion 13 of the mattress 7 from below. By changing the inclination angle α of the ejection hole 23 and the distance R between the ejection hole 23 and the vertical axis 45, various magnitudes of the component force F ₁ and the component force F ₂ can be obtained.

In the second ejection nozzle 8b of FIGS. 10 to 12, the liquid L is ejected from the ejection hole 23 of the small disk portion 36 from the pipe 18 through the union joint 32, the fixing tool 46, and the flow path 49 of the rotating shaft 44. To do. And then. Due to the component force F _{10 in} the tangential direction (circumferential direction) of the jetting force F of the liquid L, the small disk portion 36 rotates as indicated by an arrow 35. This rotational moment (the magnitude of the rotational force) is the product of the component force F ₁₀ and the distance R. The upward liquid flow 50 generated from the blades 43 by the rotation amplifies the swell of the jet output stimulus that hits the upper wall portion 13 of the mattress 7 from below. By changing the eccentric distance e of the ejection hole 23 (inflow side), the inclination angle α, and the distance R between the ejection hole 23 and the vertical axis 45, various component forces F ₁₀ and F ₂₀ can be obtained. .

As described above, the patient 4 can receive a massage effect simply by lying on the mattress 7 of the water bed 5. Since the mattress 7 is an integral body that supports the patient 4 throughout the body, only one circulation pump 10 that circulates the liquid needs to be installed. Further, the liquid L is supplied from the one circulation pump 10 to all the ejection nozzles 8. Therefore, the hollow chamber 28 in which the circulation pump 10 and the piping are disposed can be made small, and the size (height) of the water bed 5 can be suppressed. In addition, since the net-like sheet 3 that does not expand and contract in the vertical direction is laid on the upper wall portion 13 of the mattress 7 that is located near the buttocks close to the center of gravity of the body of the patient 4, the mattress 7 is B) The upper body and the lower body are integrated, but they do not sink, the internal height H ₇ is kept substantially uniform, and the patient 4 can obtain a massage evenly and efficiently over the entire body. . In addition to the buttocks, the net-like sheet 3 may be laid on the upper wall 13 of the mattress 7 located on the head, back, heel, etc. of the patient 4 with load. ₇ is kept more uniform.

  There are two or more types of ejection nozzles 8 that give a massage effect to the patient 4, and the ejection fluid pressure and rotation speed are different from each other. Therefore, the patient 4 can receive a massage effect suitable for each part of the body. Also, doctors, nurses, and attendants (or the patient 4 themselves) can individually adjust the massage of each part of the affected area by switching each ejection nozzle 8 on and off, and are suitable for each part of the body. The massage effect can be easily and efficiently received. Since this on-off switching valve may be a commercially available ball valve or the like, it is safe in terms of performance, easy maintenance, and cost can be reduced. Furthermore, if the rotation (flow rate) of the circulation pump 10 is adjusted with a controller (not shown), the strength of the massage to be received can be changed.

The nozzle head 39 of the first ejection nozzle 8a is in a recumbent shape that receives a large amount of liquid resistance when rotated, and can be rotated at a low rotational speed, and low-frequency ejection fluid pressure stimulation is applied to the upper wall portion 13 of the mattress 7. Since it can be provided, a low-frequency massage effect can be provided if it is arranged corresponding to the points such as the shoulder and back. On the other hand, since the small disk portion 36 of the second ejection nozzle 8b receives less resistance from the liquid, it can be rotated (at a higher rotation speed) than the first ejection nozzle 8a, and the upper wall portion 13 of the mattress 7 can be rotated. Since high-frequency ejection fluid pressure stimulation can be applied, it can be disposed corresponding to a pleasant affected part (acupuncture part) when a high-frequency massage effect is applied. The first ejection nozzle 8a, both second ejection nozzle 8b, the distance R of the vertical axis 45 and ejection hole 23, the inclination angle alpha, by changing the nozzle height H _8, irritating pressure of various sizes It is possible. Specifically, as the distance R is set smaller or the inclination angle α is set smaller, the number of rotations of the nozzle becomes faster and a high-frequency spiral stimulation flow can be obtained. In the second ejection nozzle 8b, various strengths and frequencies of the ejection fluid pressure can be obtained by changing the size of the blades 43.

  As described above, both the first ejection nozzle 8a and the second ejection nozzle 8b have a simple structure, and can provide a low-frequency and high-frequency massage effect. Moreover, since the ejection nozzle 8 is provided corresponding to the neck, a massage effect can be given to the acupoints of the neck. Furthermore, it is possible to easily massage only the part to be massaged by the ON / OFF operation of the switching valve 26 for each of the ejection nozzles 8.

The internal height H ₇ of the mattress 7 is preferably set to 100mm to 150 mm, the H ₇ is greater than 150 mm, hits the upper wall portion 13 of the mattress 7 (from spray nozzle 8) the pressure of the jetting liquid pressure Since the loss increases, it is difficult to efficiently provide a massage effect, a high-performance circulation pump 10 is required, and the water bed 5 becomes large. Furthermore, if H ₇ is smaller than 100 mm, there is a possibility that the upper wall portion 13 of the mattress 7 may come into contact with the upper portion of each ejection nose 8.

Preferably, setting the thickness t ₇ of the upper wall portion 13 of the mattress 7 to 0.1mm to 1.2 mm. If t ₇ is larger than 1.2 mm, the energy transmission of the jet fluid pressure hitting the upper wall portion 13 is greatly impaired, and massage points cannot be efficiently applied to the acupuncture points of the patient 4 body. Further, if t ₇ is smaller than 0.1 mm, the durability of the mattress 7 is lowered, and there is a possibility that it will be broken immediately. Further, since the temperature of the liquid in the mattress 7 is adjusted by the temperature adjuster 19, the patient 4 can always receive a massage effect on the mattress 7 having an appropriate temperature.

The present invention has the following remarkable effects by the above-described configuration.
(According to claim 1) The patient can receive a massage effect simply by lying on the mattress 7 of the water bed. Since the mattress 7 is an integral body that supports the patient throughout the entire body, only one circulation pump 10 for circulating the liquid needs to be installed. Further, all the ejection nozzles 8 are provided from this one circulation pump 10. Since the liquid L can be directly supplied, the hollow chamber in which the circulation pump 10 and the piping are disposed can be reduced, and the volume of the water bed can be reduced.

  (According to claim 2) Since there are two or more types of ejection nozzles 8 having different ejection fluid pressures and rotational speeds, an optimal massage effect can be given to each affected part (acupuncture part) of the body.

  (According to claim 3) The nozzle head 39 of the first ejection nozzle 8a has a recumbent shape that receives a large amount of resistance of the liquid when rotated, and can be rotated at a low rotational speed. Since a low-frequency spiral ejection fluid pressure stimulus can be applied to the body, a low-frequency massage effect can be provided if it is disposed corresponding to the acupoints such as the shoulder and back. On the other hand, since the small disk portion 36 of the second ejection nozzle 8b receives less resistance from the liquid, it can rotate at a higher rotational speed than the first ejection nozzle 8a, and the upper wall 13 of the mattress 7 has a high frequency. Since spiral ejection pressure stimulation can be applied, a high-frequency massage effect can be provided corresponding to a pleasant affected part (acupuncture part). Further, both the first and second ejection nozzles 8a and 8b can obtain various strengths and frequencies of the ejection fluid pressure by combining the distance between the vertical axis 45 and the ejection hole 23, and the inclination angle. By arranging the ejection nozzles 8 in various ways, an optimal massage can be given to many patients. In the second ejection nozzle 8b, various strengths and frequencies of the ejection fluid pressure can be given by changing the size of the blades 43. As described above, both the first ejection nozzle 8a and the second ejection nozzle 8b have a simple structure, and can provide a low-frequency and high-frequency massage effect.

  (According to claim 4) Since the circulation pump 10 and all the ejection nozzles 8 are directly connected, and each of the ejection nozzles 8 is provided with a switching valve 26 for individually switching on and off, the affected part By selecting only the necessary parts, the massage effect can be efficiently given intensively.

  (According to claim 5) It is possible to give a massage massage of low frequency to the acupoints such as the shoulder and the back to give an optimal massage effect.
