The pump 8 is installed on the trolley 10, sucks water stored in the storage tank 7 from the water intake port 22, pressurizes the water, applies the water to the nozzle 6 via a hose 23, and supplies the water to the nozzle 6.
From the water-proof flexible film 15.

An electric circuit for operating the pump 8 is provided with a slow start circuit 24 for starting the pump 8 slowly. The pump 8 starts slowly when the massage treatment is started (= when the switch 25 is turned on), and pumps up the water stored in the storage tank 7 from the nozzle 6 into the housing 11. When the housing 11 is filled with water, the pump 8 reaches a steady rotation, a steady jet of water is spouted, and a desired jet pressure is applied to the waterproof flexible membrane 15.

In addition, the waterproof flexible film 15 is guided so as to smoothly contact the sheet 4, and the waterproof flexible film 15 is protected from hitting a foreign substance while the housing 11 is moving.

When using the embodiment, first, a human body is put on a seat 4 stretched over the upper opening 3 of the frame 2 and the seat 4
Support the human body with. At the same time, the support roller 28 of the fluid ejection device 5 supports the human body from under the sheet 4. The support roller 28 guides the waterproof flexible film 15 so as to smoothly contact the sheet 4 and protects the waterproof flexible film 15 from hitting foreign substances while the housing 11 is moving.

When the operation of the fluid ejecting apparatus 5 is started, the pump 8 pumps up the water in the storage tank 7 and fills the storage tank 7 with water.
Immediately after starting, the pump 8 rotates slowly by the action of the slow start circuit 24, and reaches steady rotation when the housing is full of water.

Nozzle 6 provided in housing 11
Simultaneously ejects water toward the waterproof flexible film 15 and moves in the longitudinal direction of the frame 2 together with the fluid ejecting device 5 moved by the moving mechanism 16. The water spouted from the nozzle 6 gives a collision stimulus of the jet water to the human body through the waterproof flexible film 15 and the sheet 4 sequentially, and massages the stimulus.

When the fluid ejecting device 5 moves, a planar low friction member 36 provided between the sheet 4 and the waterproof flexible film 15 is provided.

Moves together with the housing 11, so that the storage tank 7 can be downsized and the amount of water can be reduced.

Further, since the amount of water used is small, the maintenance of the equipment is easy, and the water used is circulated to the storage tank 7 and the housing 11 and is sealed in both containers, so that the equipment is damaged by moisture and water droplets. Is rare. Furthermore, since the storage tank 7 is located below the moving mechanism 16 and is located on the side, the floor of the entire apparatus can be lowered, and getting on and off the seat 4 is easy. In addition, since the housing 11 is filled with water during use, the jetting sound generated by the nozzle 6 is small, and the collision sound generated by the jetting water hitting the waterproof flexible membrane 15 is also small. The massage can be done quietly and comfortably, which is convenient.

In the present invention, a planar low friction member 36 is provided between the sheet 4 and the waterproof flexible film 15. Specifically, the sheet 4 is provided with a sheet-side low friction member 26 on the back surface, and the flexible flexible film 15 is provided with a flexible film side low friction member 27 on the surface thereof. The flexible flexible film 15 can slide smoothly, no unnecessary vibration occurs at the time of sliding, and the durability of both members of the sheet 4 and the waterproof flexible film 15 is improved, which is convenient.

In the present invention, since the supporting roller 28 is provided near the housing 11, the weight can be supported by the roller 30 and the interval between the nozzle 6 and the human body can be always kept constant. The massage stimulus of such arbitrary intensity can be given, and at the same time, the roller 3
A massage stimulus of 0 can be applied, which is convenient.

In the present invention, a slow start circuit 24 for slowly starting the pump 8 is additionally provided in an electric circuit for operating the pump 8, so that the nozzle 6 slowly fills the housing 11 with water at the start of the massage. Since the jet is jetted at a predetermined pressure after the jetting, the impact sound of the jet water is suppressed and the effect of low noise is obtained. In addition, at the start of the massage, it is possible to avoid a scandal such as suddenly applying a strong jet pressure to the human body via the sheet 4 in a state where the water in the housing 11 is empty and astonishing the patient, and to provide a desired comfortable massage, It is convenient.

In the present invention, the gate valve 32 is additionally provided to the drain pipe 31. Therefore, when the pump 8 is stopped, the passage of the drain pipe 31 is partitioned so that the water in the housing 11 is not discharged. The operation can be performed in such a manner, so that the water in the housing 11 is not emptied during the consultation time when the device is used, and a low noise effect is obtained without performing the slow start operation of the pump 8. The gate valve 32 is connected to the pump 8
If it is wired so as to be closed at the same time when the pump is stopped, the passage of the drain pipe 31 is automatically partitioned at the same time when the pump 8 is stopped, so that the water in the housing 11 is not discharged, and the above-described low noise effect is obtained. Can be Also, by maintaining the water in the housing 11 full, fluctuations in jet pressure due to a decrease in water in the housing 11 can be avoided, and massage pressure applied to the human body can be stabilized, which is convenient.
