Description

[Detailed description of the invention] The present invention relates to improvements in partial bathtubs for hydrotherapy.

In conventional partial bathtubs, a cushion material is attached to the flat surface of the upper edge of the bathtub to serve as a chair.The patient sits on this chair and pulls the clothing around the affected area of the lower limb up to the area around the thigh to submerge the affected area of the lower limb in warm water. It was treated by soaking it. Alternatively, a chair separate from the bathtub may be prepared around the partial bathtub, and the patient may sit on this chair and soak the affected leg in warm water for treatment, or stand up in the bathtub and soak the affected leg in warm water for treatment. That's what I was doing.

Therefore, in order to treat the knee joint with warm water in these conventional bathtubs, one has to sit on a chair and stretch the lower leg diagonally downwards to soak the knee joint, but the disadvantage is that the clothing around the thigh gets wet. Moreover, if you tried to take a bath while standing up, the hot water needed to be at least 45 centimeters deep, making the device large and consuming a lot of water and heat.

Therefore, the present invention enables patients to immerse their lower limbs, especially their knee joints, in warm water in a comfortable posture, and also reduces the height of the upper edge of the bathtub to make it more compact, and facilitates the movement of bathing, allowing a large number of patients to bathe at the same time. The purpose of this invention is to provide a partial bath treatment device that can be used.

That is, in the present invention, the main body 2 has a bathtub 3 and a machine installation part 4.
An arm 8 having a seat 9 attached to its tip is pivoted to the upper edge 6 of one side wall of the bathtub 3 so as to be horizontally rotatable and detachable. This is a partial bath treatment device in which an arm rest 5 is installed and a nozzle mechanism 31 is provided on one side wall 18 of the bathtub 3 on the side of the machine installation section 4.

The nozzle mechanism 31 also includes a jet pump 26 installed in the machine installation section 4 and sucking and compressing hot water in the bathtub 3 and discharging it, a nozzle 19 provided on one side wall 18 of the bathtub 3, and a nozzle 19 provided on one side wall 18 of the bathtub 3. A jet flow deflection guide 21 is suspended just in front of the nozzle 19 to change the direction of the jet of hot water jetted from the nozzle 19. It consists of a drive section 25 that rotates back and forth.

Embodiments of the present invention will be described in detail below based on the drawings.

The main body 2 with the casters 1 attached to its lower surface is composed of a rectangular parallelepiped bathtub 3 and a machine installation part 4, and an armrest 5 is placed on the top of the machine installation part 4 to constitute the apparatus. A fitting recess 7 is provided in the center of the upper edge 6 of one side wall of the bathtub 3, and an inverted L-shaped arm 8 is rotatably and detachably fitted into the fitting recess 7. A knob bolt 10 is screwed into the fitting recess 7 from the outside of the device, and the vertical side of the arm 8 is pressed and fixed with the knob bolt 10 so that the height can be adjusted. A seat portion 9 having a substantially triangular shape in plan view is attached to the exposed end of the arm 8 .

At appropriate positions on the bottom wall 11 of the bathtub 3, there are a water intake port 12 for taking in hot water in the bathtub 3, a drain port 13 for draining hot water from the bathtub 3, and an air port 15 for introducing compressed air.
and are opened. On the bottom wall 11 of the bathtub 3, a bubble plate 14 having a large number of small holes 16 for blowing out compressed air on the upper surface is placed, and an opening (not shown) provided in the lower surface of the bubble plate 14 communicates with an air port 15. Ru. A planar heater 17 for heating hot water in the bathtub 3 is attached to the back of the bottom wall 11.

A nozzle mechanism 31 consisting of a jet flow pump 26, a nozzle 19, a jet flow direction guide 21, and a drive section 25 is installed inside the machine installation section 4 and inside the bathtub 3 in the direction of the machine installation section 4. That is, a nozzle 1 made of a pipe is installed on one side wall 18 of the bathtub 3 in the 4 directions of the machine installation part.
An air pipe 20 that communicates with the interior of the nozzle 19 extends upwardly from the middle of the nozzle 19 above the hot water level in the bathtub 3. A jet flow direction guide 21 is provided immediately in front of the nozzle 19 to change the direction of the jet of hot water jetted from the nozzle 19. A jet flow direction guide 21 is fixed to the lower end of a vertical rotation shaft 22 suspended from above inside the machine installation part 4 into the bathtub 3, and as described above, the jet flow direction guide 21 is attached to the nozzle. It is located just before 19. The vertical rotation shaft 22 is rotated within a certain angle range by a drive unit 25 consisting of a geared motor 23 provided above in the machine installation section 4 and a crank mechanism 24 that converts the rotational movement of the geared motor 23 into a reciprocating rotational movement. Rotated back and forth.

A jet pump 26 is installed in the lower part of the machine installation part 4 to suck in hot water in the bathtub 3, compress it, and discharge it toward the nozzle 19. A ring blower 27 that blows air toward the port 15 is installed.

the geared motor 23, the planar heater 17,
The machine is equipped with an armrest base 5, which has an operation panel 30 fixed to the front, which contains an electric circuit for controlling the energization of the jet pump 26 and the ring blower 27, and which is equipped with various illuminated push buttons 28 and a display 29. Part 4
It is mounted on the outside upper part.

The operation of the embodiment device having the above configuration will be described below.

The top center of the bathtub 3 filled with hot water or the bathtub 3
A seat 9 is positioned on the longitudinal edge of the seat 9, and the patient sits on the seat 9 in a posture similar to riding a bicycle, rests his elbows on the arm rest 5, leans his upper body forward, and sits on both lower legs or one leg. Hydrotherapy is performed by immersing the affected part of the lower limb in warm water. If the affected area is the knee joint, as shown in Figure 5, bend the thigh slightly forward, bend the area below the knee joint backwards, and soak the knee joint in warm water. In the above-mentioned bathing posture, if the upper body is placed in a vertical position without leaning forward, the rectus femoris muscle will be stretched, resulting in fatigue and pain, so the upper body is tilted forward in a natural and comfortable position.

Various illuminated push button switches 28 on the operation panel 30
By operating the jet pump 26 or the ring blower 27, jets and bubbles are administered to the affected part of the lower limb as appropriate, and the temperature of the hot water in the bathtub 3 is adjusted by energizing the planar heater 17. Further, by driving the geared motor 23, the jet flow direction guide 21 is continuously rotated back and forth in an oscillating manner within a predetermined angle range around the vertical axis, and the jet hot water from the nozzle 19 is transferred to the jet flow direction guide 21. The jet direction is continuously changed. When the drive of the geared motor 23 is stopped, the jet direction changing guide 21 is stopped at an appropriate position. By changing the direction of the jet flow in the bathtub 3, the direction of the whirlpool flow of hot water in the bathtub 3 is also alternated in forward and reverse directions.

Since the machine installation part 4 is provided with a jet flow direction guide 21 and a drive part 25 that continuously rotate back and forth, the jet hot water is jetted in multiple directions on average into the bathtub 3, and furthermore, the hot water in the bathtub 3 is directed in a vortex direction. The changes take place continuously. Therefore, with a simple and inexpensive nozzle configuration, it is possible to provide a pine surge effect by administering jet hot water and superflow hot water to multiple sites or multiple patients.

When performing hydrotherapy by immersing the affected area below the knee joint in warm water in the bathtub 3, the treatment position is to sit on the seat 9 and ride a bicycle as described above, or to do so in a separate position around the bathtub 3. A chair is prepared, and the patient sits on this chair and soaks the affected leg in warm water in a bathtub 3 for treatment.

The effects of the present invention due to the above structure and operation include providing a seat for patients who wish to treat affected areas of their lower limbs, particularly knee joints, to sit in a bicycle riding position, and a table with elbows for resting their elbows and leaning their upper body forward. Because you can bend your knees to take a bath, the depth of the warm water in the bathtub only needs to be shallow, and even though the height of the top edge of the bathtub is approximately 30cm, which is extremely low compared to conventional bathtubs, it is still possible to bathe the affected area sufficiently. It became possible. Therefore, since the device can be made smaller, running costs related to the amount of water and heat are reduced, and the manufacturing cost of the device is also reduced. Furthermore, it was possible to save pace. Furthermore, since the patient can take a bath with his or her elbows resting on the armrest and his or her upper body tilted forward, treatment can be carried out very comfortably and without the need to get the clothing worn on the lower body wet.

Furthermore, since the nozzle mechanism is provided on one side wall, it is possible to give the bathing patient a pine surge effect by administering hot water jets and hot water in excess.
