  However, the automatic defecation processing device described above has the following problems. In the automatic defecation treatment device, the diaper-like casing is directly mounted on the bedding bed, so that when washing water or urine stool leaks between the bedding bed and the diaper-like casing, the water leaks to the back of the bedding bed and the bedding bed There was a risk of getting wet. Moreover, it has been a very troublesome structure for the patient to attach the diaper-like casing to the crotch region. In addition, when the diaper-like casing is attached to the crotch part, the diaper-like casing cannot be fitted sufficiently. Furthermore, when a diaper-like casing is attached to the crotch portion in the supine state, the buttocks outside the diaper-like casing are not sufficiently stabilized, causing pain in the buttocks and crotch portions. Also, a diaper frame is provided separately, and the structure of the diaper-like casing is complicated.

  Therefore, the present inventor has developed a technique for eliminating various disadvantages of the conventional automatic defecation processing device by attaching a part of the diaper-shaped casing to the bedding and a part for processing defecation and urination by attaching it to the patient's crotch. It was. In particular, according to the technique of the present invention, as shown in FIG. 22, a support frame body 1031 in which a bottom mounting pad 1041 having a U-shaped cutout hole 1042 is inserted into a central mounting hole 1012 of a bed 1011 is inserted and the bottom mounting is performed. An L-shaped defecation treatment body 1051 is fitted into the U-shaped cutout hole 1042 of the pad 1041, and the patient wears the urination feces treatment body 1051 between the crotch and urinates in the urination feces treatment body. The urination feces are transported out of the urination stool processing body 1051 by a predetermined means. In addition, a diaper 1021 is interposed between the bed 1011 and the urination and stool processing body 1051 so as to cover the patient's crotch and prevent the scattering and leakage of filth and preventing the odor from being seen from the outside. Thus, the patient's shame is not caused.

  However, even in these automatic defecation processing devices, the crotch and the processing device are fixedly integrated so that the patient cannot move the waist to the left and right during urination, and the hips of the patient deviate from a predetermined position. If this happens, the processing unit will be overloaded and integration with the crotch will be hindered, filth will leak to the outside, the detection accuracy of various sensors will be reduced, and functional failure will occur and the cleaning function will give a predetermined result. Inconveniences such as inability to occur may occur.

  The present invention enables a support frame body fitted with a urine stool processing body attached to the crotch to swing left and right on the upper surface of the pedestal attached to the bedding bed, and follows the patient's buttocks even if it moves slightly. The urination and stool processing body also swings to create a sense of unity, prevents filth leakage as much as possible, does not hinder the sensor function, and further improves the fit when worn, An object of the present invention is to provide an automatic urination and stool processing apparatus that can be used without pain and that can simplify the overall structure.

Next, after covering the cover 59 with the folded covering portion 23 of the diaper 21, the tape at the end of the folded covering portion 23 is fixed to the waist portion 24 of the abdomen.

  (Ii) The pedestal 310 will be described.

  As shown in FIGS. 2 and 3, the pedestal 310 is formed in a rectangular shape having a constant thickness that can be fitted into the mounting hole 12 of the bedding bed 11 (see FIG. 1), and the upper surface thereof is a concave semicircular arc. A swing receiving surface 311 is formed. In addition, an adjustment stopper means 312 for restricting the swing range of the support frame 31 that is swingably placed on the swing receiving surface 311 is provided at the tip edge of the swing receiving surface 311.

  That is, the adjustment stopper means 312 has protrusions 313 and 313 projecting on the left and right sides of the semicircular arc surface of the tip edge portion of the swing receiving surface 311, and the constituent members of the support frame 31 described later are provided on the protrusions 313 and 313. By abutting, no further left-right swinging can be performed.

  Further, as shown in FIG. 4, the adjustment stopper means 312 as another embodiment has a front wall 315 of the pedestal 310 cut into a semicircular arc shape having the same shape as the swing receiving surface 311, and left and right portions of the front wall 315. The engaging pieces 320 and 320 are pivotally supported so as to be able to appear and retract. In the figure, reference numeral 317 denotes a pivot portion, and 328 denotes a guide groove.

  Therefore, by the protrusion operation of one engagement piece 320, the one engagement piece 320 and a constituent member of the support frame body 31 described later come into contact with each other, and the swing range is restricted. At this time, the support frame body 31 can swing without causing the other engagement piece 320 and the constituent members of the support frame body 31 to interfere with each other by the operation of burying the other engagement piece 320.

  The engaging pieces 320, 320 acting in this way are configured as follows.

  That is, as shown in FIGS. 5 and 6, an auxiliary wall 316 is erected on the inner side of the front wall 315 of the pedestal 310 while maintaining a predetermined interval, and between the front wall 315 and the auxiliary wall 316. The plate-like engagement pieces 320 and 320 are arranged so as to be able to appear and retract.

  The structure for moving the engaging pieces 320 and 320 in and out is as follows.

  That is, the engagement pieces 320 and 320 are pivotally supported on pins 322 and 322 (see FIG. 6) that are laid between the front wall 315 and the auxiliary wall 316, and the engagement pieces 320 and 320 are pivotally supported 317 and 317. , The engaging pieces 320 and 320 are moved in and out from the openings 343 and 343 between the front wall 315 and the auxiliary wall 316.

The front side surface of the engagement piece 320 is pressed against the back side of the front wall 315 by the bias of the spring 326. When the engagement piece 320 is buried by the pressure contact operation, the recess 327 formed in the engagement piece 320 engages with the triangular protrusion 340 formed on the back surface of the front wall 315 so that the engagement piece 320 is buried. Hold.

  That is, as shown in FIG. 5 and FIG. 10, the protrusion 340 and the recess 327 fulfill a stopper function that maintains the buried state of the engagement piece 320. In addition, a notch tongue 341 is formed on the front wall 315, and a disengagement projection 342 (see FIGS. 5 and 11) is formed on the notch tongue 341 so that the notch tongue When the piece 341 is pushed with a finger from the front side of the front wall 315, the disengagement projection 342 pushes the engagement piece 320 to the back side, and the engagement between the recess 327 of the engagement piece 320 and the projection 340 (see FIG. 10). Is released, and the engagement piece 320 can be returned from the buried state to the projected state.

  Moreover, the upper end edge of the engagement piece 320 is made into the same curved surface as a concave semicircular arc so that it may become familiar with the outer bottom face 38a of the support frame 31 mentioned later.

  That is, when the support frame 31 swings on the pedestal 310, the left and right portions of the outer bottom surface 38a of the support frame 31 come into contact with the top end surface of the engagement piece 320 as shown in FIG. As the support frame 31 is further swung, the engagement piece 320 is pushed down, and the engagement piece 320 is buried inside the front wall 315.

  The operation of burying the engagement piece 320 is performed by rotating around the pivot 317.

  When the support frame 31 swings to the original position and the contact between the outer bottom surface 38a and the engagement piece 320 is eliminated, the engagement piece 320 is moved to the spring 326 (see FIG. 6) as shown in FIG. The projecting action is caused by the urging force to project from the upper edge of the front wall 315.

  In addition, as shown in FIG. 12, through holes 318 and 318 are formed on the front wall 315 of the pedestal 310 on the left and right sides. The insertion holes 318 and 318 have wires, hard wires covered with tubes, or the like. The left and right free ends 331 and 331 of the substantially mountain-shaped fixing tool 330 formed in the above can be inserted.

  That is, as shown in FIG. 13, the fixing tool 330 is used to fix the urination / feces processing body 51, and the processing portion is formed on the inner bottom surface of the guide passage 34 by the main body portion 332 formed in a substantially mountain shape. A coupling 58 connected to the transverse member 52 of the main body 56 is fixed by pressure.

  At this time, the free ends 331 and 331 formed to protrude forward are inserted into the insertion holes 318 and 318 of the front wall 315 of the base 310.

  The free ends 331 and 331 of the fixture 330 are inserted from the insertion holes 318 and 318 so as to protrude to the back side of the front wall 315 of the base 310. The protruding free ends 331 and 331 are configured to contact the lower end surfaces of the engaging pieces 320 and 320, and restrict the range in which the engaging pieces 320 and 320 are immersed inside the base 310.

  (Iii) The support frame 31 will be described.

  As shown in FIGS. 2 to 4, the support frame 31 placed on the pedestal 310 includes a rectangular case 39 having a bottom plate 32 having an outer bottom surface 38a (see FIG. 2) formed in a convex semicircular arc. It is a box shape with an upper opening.

  That is, the outer peripheral wall 33 is erected on the outer peripheral edge of the bottom plate 32 in a state where the outer peripheral wall 33 is at least lower than the thickness of a bottom pad 41 (see FIG. 1) described later. Further, a strip-shaped guide passage 34 is provided in the center of the bottom plate 32 along the longitudinal direction, and guide walls 35 are provided on both sides.

  The guide passage 34 protrudes from the lower end of the bottom plate 32 through the lower frame body front wall 33a, and the end of the protruding portion 36 is open, so that the support frame 31 is placed on the bedding bed 11 (see FIG. 1). When mounting on the pedestal 310 mounted in the mounting hole 12, the protruding portion 36 of the guide passage 34 is fitted into the pipe passage 13 communicating with the mounting hole 12.

  The support frame 31 configured as described above forms a substantially U-shaped U-shaped space 37 between the outer peripheral wall 33 and the strip-shaped guide passage 34, and the inner bottom surface of the U-shaped space 37 is A concave semicircular arc is formed. A substantially U-shaped buttocks pad 41 (see FIG. 1), which will be described later, is fitted into the U-shaped space 37.

  Thus, the support frame 31 having the outer bottom surface 38a (see FIG. 2) having a convex semicircular arc is placed on the pedestal 310 whose inner bottom surface is a concave semicircular arc so that it can swing left and right. Swing to the left and right according to the movement of the hips and hips to absorb the shift of the hips.

  Moreover, as shown in FIG. 4, the support frame 31 swings on the pedestal 310 in accordance with the displacement and movement of the patient's buttocks, but the pedestal 310 is restricted to a certain angle with respect to the swing range. A structure for cooperating with the adjustment stopper means 312 is provided.

  That is, a belt-shaped guide passage 34 is provided at the center of the support frame 31, and this guide passage 34 protrudes out of the frame of the support frame 31 through the frame front wall 33a as described above. The guide walls 35 on both sides also protrude from the frame front wall 33a.

  When the support frame 31 having such a structure is placed on the pedestal 310, the protrusions 313 and 313 disposed on the left and right of the front wall 315 of the pedestal 310 face the outer surface of the guide wall 35.

  Therefore, when the support frame 31 is swung in one direction, the tips of the protrusions 313 and 313 of the pedestal 310 are brought into contact with each other and cannot be swung further.

  In order to be able to swing within such a certain range, only a part of the front end portion of the bottom plate 32 formed into a convex semicircular arc, that is, a lateral side of the guide wall 35 protruding forward from the bottom plate 32 is projected. It is necessary to form the flat surface 32a by cutting out only the front end portion of the bottom plate 32 having a semicircular shape.

  That is, as shown in FIG. 7, when the support frame 31 is in a neutral position where it does not swing, the space 32b formed by the flat surface 32a is positioned so that the engagement piece 320 of the base 310 is positioned. The support frame 31 can be swung without interfering with the bottom plate 32 of the support frame 31.

  As described above, the swing range is limited to a range in which the protruding protrusions 313 and 313 contact the guide wall 35.

  However, as shown in FIGS. 9 and 10, when further swinging is required, the engaging pieces 320 and 320 are manually pushed down and fixed against the spring bias. In such a state, the outer bottom surface 34 a of the guide passage 34 slides on the upper end edge of the engagement piece 320.

  That is, when the engaging piece 320 that has come into contact with the guide wall 35 is manually pushed down and buried against the spring bias, the contact with the guide wall 35 is canceled, and as shown in FIG. As the outer bottom surface 34a gets over the upper end surface 320a of the engagement pieces 320, 320, the support frame 31 is further swung to increase the inclination angle. The manually buried state of the engagement piece 320 is fixed by the engagement between the protrusion 340 and the recess 327 described above. In order to release this, it is performed by pushing the protrusion 342 for releasing engagement of the notched tongue piece 341 described above with a finger.

  (Iv) The buttocks mounting pad 41 will be described.

  The bottom pad 41 (see FIG. 1) is also formed in a substantially U shape so that it can be fitted in a substantially U-shaped U-shaped space 37 formed in the support frame 31, and has a U-shape in the center. The guide wall 35 of the guide passage 34 of the support frame 31 can be fitted into the notch space 42.
