Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the pneumatic massager with a vibration head described in Non-Patent Document 1, the storage and carrying methods of the treatment instrument including applicators of various shapes and the treatment device body, and the storage technology for efficiently replacing the applicator during treatment have not been clarified.

[0005] This invention was made to solve these problems, and aims to facilitate the replacement of applicators by allowing the treatment instrument and the treatment device body to be stored and carried, and by attaching a tray containing frequently used applicators to the outside of the housing. [Means for solving the problem]

[0006] To achieve the above objective, the wagon of the present invention comprises a housing, a tray for holding multiple applicators for delivering shock waves to a patient, a storage means for storing the multiple trays inside the housing, and a mounting means for attaching the trays to the outer surface of the housing, characterized in that one tray can be selected from the multiple trays and the selected tray can be attached to the outer surface of the housing by the mounting means. With this, applicators to be used can be separated and placed in trays and stored inside the housing of the wagon. Furthermore, depending on the treatment content, only the trays containing applicators that are frequently used in treatment can be taken out of the housing and attached to the outer surface of the housing, while trays containing applicators that are not used often can be left stored inside the housing. For this reason, when changing applicators, it is not necessary to open the housing of the wagon and take out the applicators from inside the housing each time, making the applicator replacement work easier. In addition, since it is only necessary to select the applicator to be replaced from a limited number (for example, 3) of applicators in one tray, the selection of the applicator to be replaced is easier compared to selecting from a large number of applicators.

[0007] Furthermore, it is preferable that the mounting means is a holder that can be attached to the outer surface of the housing, and that the tray is attached to the outer surface of the housing via the holder. This allows the tray to be easily attached to the outer surface of the housing via the holder attached to the outer surface of the wagon housing. For example, by attaching a tray containing applicators that are frequently used in treatment to the outer surface of the housing via the holder, the process of changing applicators during treatment becomes easier. Also, when the holder is not in use, it can be easily removed from the outer surface of the housing and stored, for example, inside the housing.

[0008] Furthermore, it is preferable that the storage means is a sliding drawer provided in the housing, and that a plurality of trays can be stored in the drawer. With this arrangement, since a plurality of trays can be stored in the sliding drawer, a plurality of trays can be stored together inside the housing, and the trays can be easily removed from inside the housing.

[0009] Furthermore, it is preferable that the drawer can be removed from the housing. This makes it easier to clean the area around the drawer inside the housing, or to clean the drawer itself, by removing the drawer.

[0010] Furthermore, it is preferable that the tray is provided with a gripping portion that can be grasped with the fingers. This makes it easier to grasp the tray by gripping the tray's gripping portion with the fingers when inserting or removing the tray from the wagon's casing, thus facilitating the operation of inserting and removing the tray from the casing.

[0011] Furthermore, it is preferable that the shock wave device comprises a wagon, a handpiece to which the applicator is detachably attached, and a device body having a control unit and / or drive unit for the handpiece. This eliminates the need to open the wagon's casing and remove the applicator from inside the casing each time the applicator is replaced, thus providing a shock wave device that facilitates applicator replacement. [Effects of the Invention]

[0012] According to the present invention, by attaching a tray for storing applicators to the outside of the trolley's casing, frequently used applicators can be taken out of the casing depending on the treatment content, eliminating the need to remove the applicators from the casing each time they need to be changed, thus simplifying the applicator replacement process. Furthermore, since a limited number of applicators can be placed in one tray, the selection of applicators can also be easily performed. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0014] Hereinafter, the wagon of the shock wave device will be described with reference to the drawings.

[0015] (First Embodiment) Figure 1 is a front view of the shock wave device M. The shock wave device M is equipped with a device body 1, a wagon 2, and a handpiece 7 used for shock wave therapy. The device body 1 is equipped with a control unit and a drive unit for the handpiece 7, which can be used to set the shock wave intensity and treatment time. In addition to the handpiece 7, the device body 1 may also be equipped with other handpieces (not shown), and may be equipped with a control unit and a drive unit for those handpieces as well. Furthermore, the device body 1 may be equipped with either the control unit or the drive unit for the handpiece 7.

[0016] Wagon 2 consists of a housing 3 and a base 5, with the main body of the device 1 being placed on the top surface 9 of the housing 3. Wagon 2 is movable by casters 6 provided on the base 5. In addition, the front side of the housing 3 is provided with a door 8 that opens outwards from the housing 3. The spatial axes of up, down, left, and right are defined as shown in Figure 1.

[0017] Figure 2 is a perspective view of the wagon 2, showing the door 8 in the open position. The door 8 is located on the front side of the housing 3 and, in this embodiment, is designed to open to the left and outward from the housing 3. The interior of the housing 3 is a storage space 15 for storing treatment instruments for shock wave therapy (for example, an applicator 14, a handpiece not shown, treatment gel, etc.). The top of the storage space 15 is equipped with a drawer mechanism 10 for moving the drawer 11a in the front-to-back direction.

[0018] Figure 3A is a plan view of drawer 11a. In plan view, drawer 11a is roughly rectangular in shape. The left and right side walls of the tray mounting surface 26 for placing trays 12a and 12b (see Figures 2 and 10) are provided with inner frames 27 that are bordered to match the outer shape of the applicator housing section 41 (see Figure 5A) of trays 12a and 12b, so that trays 12a and 12b do not move inside drawer 11a when drawer 11a or wagon 2 (see Figure 2) is moved.

[0019] Figure 3B is a side view of drawer 11a. A handle 28 for gripping when pulling out drawer 11a is provided on the front of drawer 11a so as to hang down from the front of drawer 11a, and legs 29 are provided on the rear of drawer 11a. In addition, four cylindrical stoppers 30 that protrude downward are provided on the back of tray mounting surface 26. By fitting the stoppers 30 into holes 35 (see Figure 4A) provided in drawer mechanism 10 (see Figure 2), drawer 11a and drawer mechanism 10 can be attached and detached, and when cleaning storage space 15 (see Figure 2), drawer 11a can be removed and placed on a table or other surface. At that time, drawer 11a is supported horizontally by the handle 28 and the bottom surface of legs 29.

[0020] Figure 4A is a plan view of the drawer mechanism 10 with drawer 11a extended, and Figure 4B is a plan view of the drawer mechanism 10 with drawer 11a retracted. In Figures 4A and 4B, drawer 11a is shown by a dashed line that represents only its shape. The drawer mechanism 10 consists of a first rail 31 fixed to the storage space 15 (see Figure 2), a third rail 33 that supports drawer 11a, and a second rail 32 located between the first rail 31 and the third rail 33.

[0021] The drawer mechanism 10 allows the drawer 11a to move in the front-to-back direction by moving the second rail 32 in the front-to-back direction relative to the first rail 31, and by moving the third rail 33 in the front-to-back direction relative to the second rail 32.

[0022] Furthermore, an L-shaped fitting 34 is attached to the inside of the third rail 33, and two holes 35 are provided on the left and two on the right side of the upper surface of the L-shaped fitting 34. By positioning the drawer 11a in a predetermined position on the third rail 33, the stopper 30 (see Figure 3B) fits into each hole 35. As a result, by grasping the handle 28 (see Figure 3B) of the drawer 11a and pulling or pushing it in the front-to-back direction of the housing 3 (see Figure 2), the drawer mechanism 10 makes it possible to move the drawer 11a in and out of the housing 3, and the drawer 11a becomes a storage means capable of storing multiple trays 12a and 12b inside the housing 3.

[0023] Figure 4C is a partially enlarged perspective view of the drawer mechanism 10 with the second and third rails 32 and 33 extended. To prevent excessive movement of the second rail 32 and third rail 33 when extending or retracting the drawer 11a, plate-shaped members 36 are provided at the front and rear ends of each rail. Specifically, a plate-shaped member 36a is provided at the front end of the first rail 31, a plate-shaped member 36b is provided at the front end of the second rail 32, and a plate-shaped member 36c is provided at the front end of the third rail 33. In addition, although not shown, plate-shaped members are also provided at the rear ends of the first rail 31, the second rail 32, and the third rail 33.

[0024] Specifically, the plate-shaped member 36a and the plate-shaped member at the rear end of the second rail 32 (not shown) catch on each other, preventing excessive extension of the second rail 32. The plate-shaped member 36b and the plate-shaped member at the rear end of the third rail 33 (not shown) catch on each other, preventing excessive extension of the third rail 33. Furthermore, the plate-shaped member at the rear end of the first rail 31 (not shown) and the plate-shaped member at the rear end of the second rail 32 (not shown) catch on each other, preventing excessive insertion of the second rail 32. The plate-shaped member 36b and the plate-shaped member 36c catch on each other, preventing excessive insertion of the third rail 33. This prevents each rail from coming off.

[0025] Figure 12 shows a perspective view of the handpiece 7, with dashed lines indicating the user's hand holding the handpiece 7. The user grasps the grip portion 39 of the handpiece 7 as shown in Figure 12, places the applicator 14, which is detachably attached to the tip of the main body portion 38, on the affected area, and presses the trigger switch 40. Then, a pre-set vibration stimulus is transmitted to the affected area from the device body 1 (see Figure 1).

[0026] Figure 5A is a top-down perspective view of tray 12a on drawer 11a in Figure 2, and Figure 5B is a bottom-up perspective view of the same tray 12a. In Figures 5A and 5B, the applicator 14 has been omitted from the drawings to illustrate the structure of tray 12a. In plan view, tray 12a has a shape resembling an ellipse with a part of the arc opposite the major axis straightened out. The applicator housing section 41 has three applicator holders 16 arranged horizontally for placing the applicator 14 (see Figure 2). In addition, gripping parts 17 are provided on the upper left and right sides of the applicator housing section 41, projecting in an arc outwards from the tray 12a, allowing the gripping parts 17 to be grasped with the fingers when inserting or removing tray 12a from the storage space 15 (see Figure 2).

[0027] The applicator holder 16 has a cylindrical projection 18 at its center, and the projection 18 has a gap 19 created by hollowing out its central part. Furthermore, as shown in Figures 5A and 5B, a circular recess 20 is formed by excavating around the projection 18. Note that all three applicator holders 16 provided on the tray 12a have the same shape.

[0028] Figure 6 is a partial cross-sectional view of the applicator 14 placed in the tray 12a. In Figure 6, the tray 12a is shown as a cross-sectional view along line AA in Figure 5A, and the portion of the applicator 14 fitted into the applicator holder 16 is also shown as a cross-sectional view. The applicator 14 is configured such that the case 22 surrounds the piston 21 that transmits shock waves to the affected area. In Figure 6, the side facing upwards is the surface of the piston 21 that contacts the affected area, and the side facing downwards is the rear end of the piston 21b and the rear end of the case 22b that fit with the main body 38 of the handpiece 7 (see Figure 12).

[0029] When inserting the applicator 14 into the tray 12a, as shown in Figure 6, the rear end 21b of the piston 21 is fitted into the gap 19 in the center of the applicator receiver 16, and the rear end 22b of the case 22 is fitted into the recess 20. This fixes the position of the applicator 14 and prevents the applicators from shifting position and colliding with each other even when the tray 12a is carried.

[0030] Furthermore, the applicator holder 16 is not designed to have a specific shape for each individual applicator. Therefore, even if the applicators 14a, 14b, and 14c shown in Figure 6 have different shapes, the applicator 14 can be placed into the applicator holder 16 using the method described above, without having to search for a dedicated applicator holder each time.

[0031] Since the applicator 14 is suitable for different treatments depending on its shape, as shown in Figure 2, it is necessary to select the tray 12a containing the applicator 14 suitable for the treatment from among the multiple trays 12a that store multiple applicators. Therefore, by attaching the tray 12a to the outer surface 4 of the housing via the holder 13a, it becomes unnecessary to open and close the door 8 each time and to take the tray 12a in and out of the housing 3, making it easier to change to the appropriate applicator 14 for the treatment. Although not shown, a mounting means such as a magnet is provided on the inside or outside of the long side of the holder 13a, thereby allowing the holder 13a to be attached to the outer surface 4 of the housing. In Figure 2, the holder 13a is attached to the right side of the housing 3, but the holder 13a may also be attached to the left side of the housing 3 or to the door 8.

[0032] Figure 7 is a perspective view of the holder 13a in the first embodiment. When the tray 12a (see Figure 6) is placed in the tray receiver 23 of the holder 13a, a gap is created between the upper surface of the holder 13a and the lower surface of the gripping portion 17 (see Figure 6) of the tray 12a for inserting fingers. Therefore, the gripping portion 17 can be grasped with fingers, making it easy to remove the tray 12a from the holder 13a.

[0033] (Second example) Figure 8 is a diagram showing the usage state of holder 13b in the second embodiment. In the second embodiment, the shape of holder 13b differs from that of holder 13a in the first embodiment (see Figure 7), but the other configurations are the same as in the first embodiment. Holder 13b is a mounting means composed of a pair of rails. One of the rails is shaped like the Japanese katakana character "コ", and the other is shaped like the Japanese katakana character "コ" reversed horizontally. This pair of rails are attached to the outer surface 4 of the housing (see Figure 2) one at a time by means of magnets or the like with their openings facing each other, and the mounting position on the outer surface 4 of the housing can be freely changed as appropriate. Alternatively, holder 13b may be fixed in a predetermined position as part of the outer surface 4 of the housing (see Figure 2).

[0034] The spacing L of the openings in the holder 13b is approximately the length of the longer side of the tray 12a, excluding the gripping portion 17. By inserting the gripping portion 17 of the tray 12a into the openings of the holder 13b, the tray 12a can be detachably attached to the outer surface 4 of the housing (see Figure 2).

[0035] (Third example) Figure 9 is a partial view of the housing 3 equipped with a tray hanger 24 in the third embodiment. In the third embodiment, a tray hanger 24 is provided instead of the holders 13a and 13b (see Figures 7 and 8) in the first and second embodiments, and the shape of the tray 12b (see Figure 10) that is mounted on the outer surface 4 of the housing is different. The other configurations are the same as in the first and second embodiments.

[0036] The tray hanger 24 has sides that extend horizontally in the front-to-back direction of the housing 3, and both ends of the hanger are bent toward the outer surface 4 of the housing, with the ends fixed to the outer surface 4 of the housing.

[0037] Figure 10 is a perspective view of tray 12b in the third embodiment. Tray 12b differs from tray 12a (see Figure 8) only in that it has a pair of hooking pieces 25 on one of its long sides for hooking onto tray hanger 24 (see Figure 9). In the third embodiment, tray 12b can be detachably attached to the outer surface 4 of the housing by hooking these hooking pieces 25 onto the side of tray hanger 24 that extends horizontally in the front-rear direction.

[0038] Furthermore, although the tray hanger 24 is shown on the right side of the housing 3 in Figure 9, it may also be shown on the left side, or on both the left and right sides.

[0039] (Drawer torture) Figure 11 is a plan view of the drawer mechanism 10 with drawer 11b extended. The method of storing tray 12a (see Figure 5A) in drawer 11b differs from that of drawer 11a (see Figure 3A) described in the first embodiment, but the other configurations are the same. Drawer 11b shown in Figure 11 is provided with a tray receiving hole 37 for fitting tray 12a, and instead of placing tray 12a on top as in drawer 11a (see Figure 3A), it is stored by fitting the applicator housing section 41 (see Figure 5A) into the tray receiving hole 37. The tray receiving hole 37 may also be shaped to hold tray 12b (see Figure 10) and fit shallowly without interfering with the hook piece 25 (see Figure 10). Alternatively, the tray receiving hole 37 may be configured so that tray 12b including the hook piece 25 can be stored in the tray receiving hole 37. [Industrial applicability]

[0040] The present invention allows for the detachable attachment of a tray for holding an applicator detachable from a handpiece used for shock wave therapy to the outer surface of the housing, and therefore, the first to third embodiments and modified versions of the drawer can be used in combination.
