  The present invention relates to a urination support apparatus that supports urination, and more particularly, to a urination support apparatus that is provided inside a human body and presses a bladder.

As a background art, there is a urination device disclosed in International Publication WO99 / 01092. The urination device as the background art includes a flexible tube, a plunger, a cradle, an elastic member, an electromagnetic solenoid, and an actuator. The flexible tube has an inlet and an outlet. The plunger has a pressing portion at one end and a contact portion at the other end. The cradle supports the flexible tube below the plunger pressing portion. The elastic member presses and closes the pressing portion of the plunger against the flexible tube in a normal state to compress and close the flexible tube between the pressing portion and the cradle. The electromagnetic solenoid selectively attracts and repels the contact portion of the plunger. The actuator selectively connects the electromagnetic solenoid to the power source. In this configuration, the inlet of the flexible tube is connected to the bladder through the catheter, and the outlet of the flexible tube is connected to the urine collection bag through the conduit. When the urine pressure in the bladder reaches a predetermined value, the electromagnetic solenoid is biased by the actuator, the pressing portion of the plunger is retracted, and the compression blockage of the flexible tube is released. The urine pressure in the bladder communicating with the injection port of the flexible tube is set to a predetermined value, and when the urine pressure reaches the predetermined value, all the urine in the bladder is discharged from the discharge port of the tube to the external urine collection bag. After urination, the above operation is repeated again. As described above, according to the urination device of the background art, although the bladder is connected to the urine collection bag through the catheter, the urination and the urination can be repeated for urine storage and urination as usual. It is possible to urinate without abolishing the bladder function.
International Publication WO99 / 01092

  However, the urination device of the background art is configured as described above, can be used only with the catheter attached to the bladder, and various preparations are necessary before the urination operation, and the device is placed. There is a problem that urination using such a device can be performed only at a place, and the convenience is inferior.

  The present invention has been made to solve the above-mentioned problems, and performs urination in the same manner as a person with normal bladder function without eliminating the bladder function and without any preparation in any place. An object of the present invention is to provide a urination support device that supports the urination.

  The urination support device according to the present invention includes a long support portion fixed to any bone around the bladder, a first spring portion that expands and contracts due to temperature change on one side of the support portion, and the other side of the support portion And a second spring portion that expands and contracts due to a temperature change. The first spring portion and the second spring portion each have a first heat conduction plate, and the second heat conduction plate has a Peltier that can conduct heat to the spring portion. An expansion / contraction mechanism disposed with an element interposed is disposed on both sides of a pressing portion that presses the bladder via a link shaft pivoted on the support portion, and the link shaft is a first spring portion of each expansion / contraction mechanism. And it has a control part which joins with the 2nd spring part and controls the Peltier device. As described above, in the present invention, the support portion, the first spring portion, and the second spring portion are provided, and the first heat conduction plate and the second spring portion are respectively provided in the first spring portion and the second spring portion. An expansion and contraction mechanism in which a heat conduction plate is disposed with a Peltier element interposed so that heat conduction can be performed on the spring portion is disposed on both ends of the pressing portion that presses the bladder via link shafts pivoted on the support portion. The link shaft is joined to the first spring portion and the second spring portion of each expansion / contraction mechanism, and has a control unit that controls the Peltier element. Heat absorption occurs, and the heat is conducted to the first spring part (or the second spring part) of the expansion / contraction mechanism on both sides of the pressing part via a heat conduction plate, and expands or contracts. In response, the link shaft tilts around the pivot point of the support part, and the pressing part is pressed to press the bladder , Urine oppressed the bladder is discharged through the urethra, after only flow a current to the Peltier element can be performed smoothly urination act through a mechanical operation. On the other hand, while the current flows through the Peltier element, the link shaft is tilted and the state where the pressing part presses the bladder is maintained. Therefore, the current is stopped from flowing through the Peltier element, and the heat of the spring part reaches the normal value. The link shaft can be raised to release the pressure on the bladder from the pressing portion. Further, in order to release the bladder from the compressed state more quickly, the first spring and the second spring are respectively supplied to the second spring by flowing a current in the direction opposite to the current direction with respect to the Peltier element. As a result, the first spring acts and the link shaft can be raised quickly.

  Moreover, the urination assistance apparatus according to the present invention is provided with two expansion / contraction mechanisms on both sides of the pressing portion as required. As described above, in the present invention, since the two expansion / contraction mechanisms are provided on both sides of the pressing portion, the pressing portion is pressed down via the link shaft using a total of four expansion / contraction mechanisms, and can be stably distributed. The pressing portion can be pressed, and the bladder can be appropriately compressed.

  In addition, the urination assisting apparatus according to the present invention, if necessary, sets one transformation start temperature of the first spring part or the second spring part to a human normal temperature or higher, and sets the other transformation end temperature to a human normal temperature. It is as follows. Thus, in the present invention, one of the first spring portion and the second spring portion has a transformation start temperature not less than human normal heat and the other transformation end temperature not greater than human normal heat. Due to the heat generation and heat absorption of the element, the inner spring is degenerated and the outer spring is extended, and the above-described operation becomes possible.

  Moreover, the urination assistance apparatus according to the present invention covers the first spring part and the second spring part with a bellows that expands and contracts as necessary. As described above, in the present invention, the first spring portion and the second spring portion are covered with the bellows that expands and contracts, so that the first spring portion and the second spring portion are extended by driving the apparatus. Even the internal organs will not be damaged.

  In addition, in the urination support apparatus according to the present invention, the portion of the pressing portion that contacts the bladder has a shape corresponding to the shape of the bladder, as necessary. As described above, in the present invention, the portion of the pressing portion that contacts the bladder has a shape corresponding to the shape of the bladder, so that the bladder is smoothly compressed without wasting the pressing force by the link shaft. be able to. Here, when the pressing part is not in such a shape, the bladder is deformed in many directions without being suppressed, so that not only can not be compressed efficiently, but also the extension of the spring is necessary and driven. The area is wide and the influence on other organs is also large and undesirable.

  Moreover, the urination assistance apparatus according to the present invention has a remote controller for sending a command to the control unit outside the human body as necessary. As described above, in the present invention, since the remote controller that sends a command to the control unit is provided outside the human body, the urination action can be smoothly realized according to the patient's request. Moreover, when a caregiver or a medical staff provides care, the urination can be performed according to the rules regardless of the case of the patient. In the case of using a catheter, there has been a problem that operation is difficult for a caregiver, regardless of medical personnel.

  Moreover, the urination support apparatus according to the present invention obtains drive power from radio waves as necessary. As described above, in the present invention, since driving power is obtained from radio waves, power can be supplied permanently from the outside, and the burden on the patient can be greatly reduced compared to the case where power is supplied by a battery. Can do. As a method for obtaining driving power from radio waves, there is generally a method in which a coil is provided, a high frequency is obtained from the coil, and rectification is obtained by rectification.

  Further, the urination assisting device according to the present invention includes a long base portion fixed to any bone around the bladder, and one end supported by the base portion, and a displacement whose shape changes due to a temperature change or a voltage change. The displacement part changes the shape by temperature change or voltage change and compresses the bladder, so that the base part fixed to the bone is a fixing point, and the displacement part changes shape by temperature change or voltage change. The urinary bladder can be repeatedly compressed with the same movement, and urination can be supported repeatedly stably. If the movement varies, the movement unexpected by the installer is performed, which may be harmful to other organs in the worst case.

  Further, the urination support device according to the present invention includes a long base portion fixed to any bone around the bladder, a telescopic mechanism portion that is located around the bladder and includes a movable object and a movable receiver, and the base. It is fixed to the bone because it includes a tilting portion that is supported at one end and rotatable to the bladder side around the one end, and a link member that connects the movable object and the tilting portion of the telescopic mechanism. By using the base part as a fixed point and pressing the telescopic mechanism part from outside the body with the user's hand, the movable object is housed in the movable receiver, and the link material connected to the movable object moves in the same way, and the tilting part also moves to the bladder. Tilt to the side, the bladder can be repeatedly pressed with the same movement, and urination can be supported repeatedly stably.

  Moreover, since the urination assistance apparatus according to the present invention is provided with a cushion material at the bladder contact portion of the displacement portion as needed, it can be compressed without damaging the bladder.

The flexible jacket itself is molded from one or more of the group consisting of silicon, polyurethane and biocompatible polymer.

(First embodiment of the present invention)
A urination support apparatus according to a first embodiment of the present invention will be described with reference to FIGS. 1 is a schematic diagram of a urination support apparatus according to the present embodiment, FIG. 2 is a state diagram in which the bladder of the urination support apparatus according to the present embodiment is not compressed, and FIG. 3 is a diagram of the bladder of the urination support apparatus according to the present embodiment. FIG. 4 and FIG. 5 are overall views of the urination support apparatus according to the present embodiment, and FIG. 6 is an exemplary diagram in which the urination support apparatus according to the present embodiment is installed.

  In each of the drawings, the urination assisting device according to the present embodiment includes a long support portion 1 fixed to any bone around the bladder, and a first spring portion that expands and contracts on one side of the support portion 1 due to temperature change. 12 and a second spring portion 13 that expands and contracts due to a temperature change on the other side of the support portion. The first heat conduction plate 14 and the second spring portion 13 are respectively provided on the first spring portion 12 and the second spring portion 13. A link shaft pivoted by the support portion 11 on both sides of the pressing portion 20 that presses the bladder is provided with the expansion / contraction mechanism 10 in which the heat conduction plate 15 is disposed on the spring portions 12 and 13 with the Peltier element 16 interposed therebetween. The link shaft 30 is connected to the first spring portion 12 and the second spring portion 13 of each expansion / contraction mechanism 10 and has a control portion (not shown) for controlling the Peltier element 16. It is a configuration. In this embodiment, four extension mechanisms 10 are used.

  In the present embodiment, the first spring portion 12 is an inner spring on the bladder side, and specifically, a shape memory alloy is used. If this shape memory alloy is used, even if it is plastically deformed by an external force, high elasticity can be recovered by heating, and the shape can be reproduced while being memorized. In particular, the Ti—Ni shape memory alloy is excellent in biocompatibility as a medical material. When the living body temperature is based on 36.5 [° C.], the spring constant is increased at this living body temperature, and the spring constant is lowered to be softened by cooling to 26 [° C.]. That is, 26 [° C.] is the transformation start temperature, and 36.5 [° C.] is the transformation end temperature. The numerical value here is only one specific example.

  In the present embodiment, the second spring portion 13 is an outer spring on the bladder side, and specifically, a shape memory alloy is used similarly to the first spring portion 12. Similarly, when the living body temperature is based on 36.5 [° C.], the spring constant is lowered at this living body temperature, and the spring constant is increased by heating to 46 [° C.]. To do. That is, a temperature of 36.5 [° C.] or higher is set as the transformation start temperature, and 46 [° C.] is set as the transformation end temperature. The numerical value here is only one specific example.

  The Peltier element 16 is a semiconductor element, and when a current is passed, the surface of the element absorbs heat, the other surface generates heat (heat radiation), and a temperature difference can be generated between both surfaces. By using the Peltier element 16, the first spring portion 12 and the second spring portion 13 can absorb heat and generate heat, respectively.

  The heat conductive plates 14 and 15 are an aluminum plate and copper, and any other medium capable of conducting heat can be applied. In this embodiment, the Peltier element is sandwiched between aluminum plates, and heat conduction is performed from the aluminum plate to the shape memory alloy via the copper plate. Here, when conducting heat from the copper plate to the first spring portion 12 and the second spring portion 13, the copper plate can be simply connected to the first spring portion 12 and the second spring portion 13. Since the first spring part 12 and the second spring part 13 are movable parts, the parts that can be contacted are limited and smooth heat conduction cannot be realized. Therefore, the first spring portion 12 and the second spring portion 13 are covered with a cylindrical one that can be enclosed, and the cylinder is filled with liquid, and the first spring portion 12 and the second spring portion 13 are formed from a copper plate. Heat conduction to the can be made more smoothly. According to this, as compared with the case where heat conduction is performed by the contact of the part, heat can be conducted without any bias since the heat is totally conducted, which is also desirable in the operation of the spring portion. Furthermore, it is desirable that the movable part is covered with a cylindrical object in consideration of the fact that the urination support apparatus is installed in the human body. Furthermore, even if it covers with the pipe | tube 51, let the upper part be the covering body 50 comprised with the bellows 52 which can be elastic. A specific example of the elastic bellows is a bellows tube made of silicon. As the liquid to be filled, water, physiological saline or the like can be considered.

  The said control part is comprised with a microcomputer or an electronic circuit, and performs control which sends an electric current with respect to the Peltier device 16 according to an external request | requirement. For example, the control unit is installed in a non-movable support unit. Similarly, a power supply unit (not shown) that supplies current to the control unit and the Peltier element 16 is also provided in a non-movable support unit.

  The tube 51 and the support portion 11 may be directly joined to the iliac bone, the pubic bone, the sciatica, etc., but for example, the tube 51 and the support portion 11 are fixed to the base 40 as shown in FIG. 40 may be configured to be joined to the iliac bone or the like. A hole 60 is formed in the base 40 so that the bladder can be accommodated from above. In addition, since the hole 60 is provided, a space for the prostate that is a close organ of the bladder and a space for the urethra that is a passage for urine are also secured. Further, the base 40 can be configured as one, and as shown in FIG. 5, a base 40 may be provided for each of the telescopic mechanisms 10, and in this case, the hole 60 is provided between the bases 40. Will be formed. 4 and FIG. 5, there is no cylinder at the joint portion between the cylinder 51 related to the first spring part and the cylinder 52 related to the second spring part. Is satisfied, and the first heat conductive plate 14, the second heat conductive plate 15, and the Peltier element 16 are arranged in the base. In particular, in FIG. 4, it is a donut shape, but is configured to be separated for each telescopic mechanism 10. In short, this is equivalent to the fact that the tube of the joint portion is formed on the base 40. In the base, the control unit and the power supply unit, which are described above as being arranged on the support unit 11, can also be arranged on the base 40.

  Next, the operation of the urination support apparatus according to the present embodiment will be described. The urination device must be installed on the human body beforehand so that the bladder 100 can be accommodated by laparotomy. FIG. 6 is an exemplary diagram in which the urination support apparatus is installed on the human body.

  A patient who has been operatively provided with such a urination support apparatus goes to the toilet with a remote control (not shown) of the urination support apparatus when he / she wishes to urinate. If it is a man, a patient who is standing in front of a urinal for standing urinals and cannot urinate with the genitals oriented in a predetermined direction first tries to produce urine by relying on his / her muscle strength. Then, after making a certain attempt, the start button on the remote control is pressed.

  When such a button is pressed, a drive command is transmitted from the remote control to the control unit. The control unit receives the drive command and causes a current to flow through the Peltier element 16. When a current flows, the Peltier element 16 absorbs heat from the first heat conduction plate 14 and radiates the heat to the second heat conduction plate 15. The temperature of the filling water in the cylinder 51 in which the first heat conduction plate 14 is provided is lowered and approaches the transformation start temperature direction. Then, the first spring portion 12 extends. On the other hand, the temperature of the filling water in the cylinder 51 in which the second heat conduction plate 15 is provided rises and approaches the transformation end temperature direction. Then, the second spring portion 12 is degenerated. By the extension of the first spring part 12 and the contraction of the second spring part 12, the link shaft 30 is tilted from the initial position, and the pressing part 20 is pressed down. The pressing unit 20 is pressed downward by the pressing and presses the bladder 100. Due to such pressing, the bladder 100 increases the internal pressure against urine, and urine is discharged from the urethra.

  A patient who has determined that urine has been discharged and no longer intends to urinate, presses the end button on the remote control. The remote controller transmits the end command to the control unit. The control unit to which the end command is transmitted stops the current flowing through the Peltier element 16, and then flows the current in the reverse direction. Then, the heat absorption and the heat dissipation are reversed, the second heat conduction plate 15 absorbs heat, and the heat is radiated to the first heat conduction plate 14. The temperature of the filling water in the cylinder 51 in which the second heat conduction plate 15 is provided is lowered and approaches the transformation start temperature direction. As a result, the second spring portion 13 extends. On the other hand, the temperature of the filling water in the cylinder 51 in which the first heat conducting plate 14 is provided rises and approaches the transformation end temperature direction. Then, the first spring portion 13 is degenerated. By the extension of the second spring portion 13 and the contraction of the first spring portion 12, the link shaft 30 returns from the inclined state. The pressing part 20 is released from the pressing and is pushed up by the bladder 100.

  The urination action is thus completed. Here, the end command is transmitted to the control unit using the remote controller, but if the command is not transmitted, that is, even if the patient forgets to press the end button, the control unit stops flowing current when a predetermined time has elapsed. According to this, after a predetermined time has elapsed, the temperature of the filling water becomes the body temperature, the second spring portion 13 is expanded, and the first spring portion 12 is degenerated, thereby The link shaft 30 returns from the tilted state. Then, the pressing unit 20 does not press the bladder 100. Thus, even if the patient forgets, it can be restored naturally. Further, when the remote controller is lost, even when the control unit breaks down, the return state is always maintained, so that the state where the bladder 100 is pressed does not continue, which is excellent in terms of safety.

  As described above, according to the urination support device according to the present embodiment, the support portion 11, the first spring portion 12, and the second spring portion 13 are provided, and the first spring portion 12 and the second spring portion 13 are provided. A pressing part 20 that presses the bladder is provided with a telescopic mechanism 10 in which the first heat conducting plate 14 and the second heat conducting plate 15 are arranged in the spring parts 12 and 13 with the Peltier element 16 interposed therebetween, respectively. The link shafts 30 are disposed at both ends of the Peltier element via the link shafts 30 pivoted on the support portion 11, and the link shafts 30 are joined to the first spring portions 12 and the second spring portions 13 of the respective expansion and contraction mechanisms. 16 has a control unit for controlling the current, the heat is generated on the one hand by flowing an electric current through the Peltier element 16, and the heat is absorbed on the other side. The heat is applied to the first spring of the expansion / contraction mechanism 10 on both sides of the pressing unit 20. The heat conduction plate 14 (or the second spring portion 13) or the portion 12 (or the second spring portion 13) 5) is conducted and extended or retracted through the interposition of the spring portion, the link shaft 30 tilts around the pivot point of the support portion 11 according to the expansion and contraction of the spring portion, the pressing portion 20 is pressed down to press the bladder 100, and compression The urine in the bladder 100 thus discharged is discharged through the urethra, and by simply passing an electric current through the Peltier element 16, the urination can be performed smoothly through a mechanical operation.

  In the urination support apparatus according to the present embodiment, an adjustment knob is provided on the remote controller, and the amount of current flowing through the Peltier element 16 can be adjusted according to the adjustment knob adjustment, thereby pressing the bladder 100 more quickly. And how much the bladder 100 is pressed can be adjusted.

(Other embodiments of the present invention)
Although the urination support apparatus according to the second embodiment has the configuration shown in FIG. 7, the configuration shown in FIG. 10, which is an enlarged view of the main part corresponding to FIG. 7B, can be used. A long base part 110 fixed to some bones, an end part 311 supported at one end by the base part 110 and maintaining a predetermined long shape, one end fixed to the start part 311, and the like The link member 313 is composed of a piezoelectric element at the end, and the other end of the link member 313 is positioned at the base portion 110 of the activation unit 311 in a normal state, and moves in a downward direction along the base portion 110 when voltage is applied. The volume of the link member 313 is changed by applying a voltage to the piezoelectric element portion of the link member 313, and the other end of the link member 313 along the base portion 110 is displaced by a predetermined amount (∇ in the drawing). Move and one end of link material 313 The fixed activation unit 311 is activated (see FIG. 10B. Note that FIG. 10A shows a state before activation), and the other end of the activation unit repeatedly presses the bladder 100 with the same operation. And can stably support urination repeatedly. Here, the piezoelectric element portion of the link member 313 may be formed of a shape memory alloy and similarly displaced by a predetermined amount. Further, the connecting portion of the base portion 110 with the link material 313 may be a piezoelectric element or a shape memory alloy, and the link material 313 may be displaced by the volume change of the base portion 110.

  Similarly, in the configuration of the base part 110, the starting part 311, and the link member 313, the connection end of the base part 110 of the link member 313 serves as a joint, and this joint part causes the base part 110 to function as a reel. The connecting end of the base portion 110 of the starting portion 311 can be a fixed end, and the fixed end and the joint are bent at the center and connected by an expanding material having two extending hands 314a and 314b. A shape memory alloy is arranged in the center of the extension of the opening material 314, and the expansion material 314 is narrowed with the shape memory alloy being short in a normal state (see FIG. 11 (a)). In a state where the memory alloy is long, the activation member 311 is activated with the expansion material 314 as a wide angle (see FIG. 11B), and similarly, the bladder can be compressed to support urination. In this case, a piezoelectric element can be used in place of the shape memory alloy, and volume expansion can be caused by applying or not applying a voltage to the piezoelectric element to function in the same manner as the shape memory alloy.

  Further, the configuration of FIG. 11 is an example and can be operated by a general actuator. As another example, the configuration of FIG. 12 can be operated similarly.
