Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a hyperthermia auxiliary device. Background Art

[0002] Tumor hyperthermia is a method of treating tumors by heating. This method has become the fifth major tumor treatment means after surgery, radiotherapy, chemotherapy, and immunotherapy, and is known as the "tumor green therapy". The basic principle of tumor hyperthermia is to use physical energy to heat the whole body or part of the human body, so that the temperature of the tumor tissue rises to the effective treatment temperature (usually 41 - 43°C or higher) and lasts for a certain period of time. Due to the difference in temperature tolerance between normal tissues and tumor cells, this treatment method can effectively kill tumor cells without damaging normal tissues.

[0003] In the prior art, an extracorporeal electric field hyperthermia machine is one of the commonly used devices for tumor hyperthermia. The extracorporeal electric field hyperthermia machine uses a high-frequency electromagnetic field (usually 13.56 MHz) to generate endogenous heat inside the human body, and kills or inhibits the growth of tumor cells through a thermobiological effect. It includes a hyperthermia machine main body that generates a high-frequency electromagnetic field and a treatment bed for the patient to lie on. A bearing plate is slidably connected to the top surface of the treatment bed along the horizontal direction. The bearing plate supports the patient's body and pushes the patient's body to move on the horizontal plane, so that the patient's body makes a relative movement with the hyperthermia machine main body to perform hyperthermia work on tumors at different positions of the patient's body.

[0004] However, the heights of the treatment bed and the bearing plate are fixed. When a patient with limited mobility needs to undergo hyperthermia, it is difficult for them to climb onto the treatment bed, and often requires the assistance of medical staff. This not only causes inconvenience to the patient but also increases the workload of medical staff. Summary of the Utility Model

[0042] Please refer to Figures 1-5 , the present utility model provides a technical solution: a thermotherapy assistance device, including a treatment bed 11 and a bearing plate 12. The bearing plate 12 is parallel to the top surface of the treatment bed 11 and is slidably connected along the length direction of the treatment bed 11. A first sliding plate 21 is slidably connected to the top surface of the bearing plate 12 along the length direction of the treatment bed 11;

[0043] One end of the first sliding plate 21 is hinged to a second sliding plate 22. The second sliding plate 22 can rotate around the hinge point as an axis, and the plane of the rotation trajectory of the second sliding plate 22 is parallel to the sliding trajectory of the first sliding plate 21, and the second sliding plate 22 can be pushed out of the bearing plate 12 when the first sliding plate 21 slides;

[0044] A footrest plate 23 is connected to the middle of the side of the second sliding plate 22 facing away from the bearing plate 12. The footrest plate 23 is perpendicular to the second sliding plate 22 and perpendicular to the plane of the rotation trajectory of the second sliding plate 22.

[0045] A treatment hole 131 extending in the horizontal direction is provided in the middle of the hyperthermia machine main body 13. The treatment bed 11 is placed on one side of the hyperthermia machine main body 13, and the head of the treatment bed 11 is aligned with one end opening of the treatment hole 131. The second slide plate 22 is located at the tail of the treatment bed 11. A second chute 113 extending in the length direction is provided on the top surface of the treatment bed 11. The bottom of the bearing plate 12 is inserted into the second chute 113 and is in sliding fit; a rack 36 extending in the length direction of the treatment bed 11 is fixedly connected to one side wall of the bearing plate 12. A gear 35 meshing with the rack 36 is provided on one side wall of the second chute 113. One end of the gear 35 penetrates through the side wall of the second chute 113 and extends out of the second chute 113 and is in rotational fit. The plane of the rotation trajectory of the gear 35 is parallel to the sliding trajectory of the first slide plate 21. A second rotating rod 34 is provided at the end of the gear 35 outside the second chute 113. One end of the second rotating rod 34 is fixedly connected to the gear 35, and the other end extends radially away from the gear 35. The bearing plate 12 is driven to rotate on the treatment bed 11 by manually rotating the second rotating rod 34.

[0046] The first slide plate 21 can slide on the bearing plate 12. One end of the second slide plate 22 is hinged to one end of the first slide plate 21 near the tail of the treatment bed 11. A footrest plate 23 is provided on the second slide plate 22. Through the step structure formed by the footrest plate 23 and the second slide plate 22, the plane of the footrest plate 23 facing the first slide plate 21 is the stepping surface of the step. The patient can step on the footrest plate 23 to shorten the height difference between the feet and the top surface of the treatment bed 11, so as to facilitate the patient to climb onto the treatment bed 11.

[0047] During use, when the patient needs to climb onto the treatment bed 11, step on the footrest plate 23, lean or sit on the first slide plate 21 with the buttocks, and push the first slide plate 21 to slide on the bearing plate 12 close to the hyperthermia machine main body 13. The first slide plate 21 exerts a horizontal pulling force on the second slide plate 22, so that the second slide plate 22 follows the first slide plate 21 to move close to the treatment machine main body 13, so that one end of the bearing plate 12 near the tail of the treatment bed 11 presses against the second slide plate 22, causing the second slide plate 22 to rotate on the first slide plate 21 and continue to move on the horizontal plane together with the first slide plate 21 until the second slide plate 22 moves to a horizontal state; under the lifting action of the footrest plate 23, the patient's legs are pushed up until the patient sits stably on the first slide plate 21 and the second slide plate 22, achieving the purpose of assisting the patient to board the treatment bed 11 and reducing the work intensity of medical staff.

[0048] When hyperthermia is required, manually rotate the second rotating rod 34 in the positive direction. The second rotating rod 34 drives the bearing plate 12 to slide on the treatment bed 11 through the gear 35 and the rack 36, so that the bearing plate 12 drives the first sliding plate 21, the second sliding plate 22 and the patient to move on the treatment bed 11, and the bearing plate 12 drives the patient's body to move and insert into the treatment hole 131. The hyperthermia machine main body 13 generates a high-frequency electromagnetic field to perform hyperthermia work.

[0049] In this embodiment: a first chute 121 extending along the length direction is formed on the top surface of the bearing plate 12. A slide bar 122 is slidably fitted in the first chute 121, and one side of the slide bar 122 protrudes out of the first chute 121 and is fixedly connected to the first sliding plate 21.

[0050] A driving part for driving the first sliding plate 21 to slide on the bearing plate 12 is arranged between the first sliding plate 21 and the bearing plate 12.

[0051] The cross section of the first chute 121 is T-shaped. By arranging the slide bar 122 in the first chute 121 and fixedly connecting one side of the slide bar 122 to the first sliding plate 21, the free rotation of the first sliding plate 21 on the bearing plate 12 is restricted, so that the first sliding plate 21 slides on the bearing plate 12 in a single degree of freedom along the length direction of the treatment bed 11, so as to stably drive the second sliding plate 22 to rotate to assist the patient to climb onto the treatment bed 11.

[0052] In this embodiment: a cavity 1211 is formed in the side wall of the first chute 121 facing away from the second sliding plate 22. The driving part includes a worm gear 31 arranged in the cavity 1211 and a worm 32 meshing with the worm gear 31. The two ends of the worm gear 31 are respectively rotatably fitted with the top wall and the bottom wall of the cavity 1211, and the top end of the worm gear 31 penetrates through the top wall of the cavity 1211 and extends out of the cavity 1211.

[0053] One end of the worm 32 penetrates through the side wall of the cavity 1211 and extends into the first chute 121, and penetrates through the bottom of the first sliding plate 21 and is connected by thread fit. The worm 32 is rotatably fitted with the side wall of the cavity 1211.

[0054] During use, when the second sliding plate 22 needs to be adjusted to a horizontal state, rotate the worm gear 31 in the positive direction. The worm gear 31 drives the worm 32 to rotate in the positive direction. The worm 32 pushes the slide bar 122 and the first sliding plate 21 to move together on the bearing plate 12 towards the direction of the hyperthermia machine main body 13, so that the second sliding plate 22 is pushed and rotated by one end of the bearing plate 12 until the second sliding plate 22 moves onto the bearing plate 12 and is in a horizontal state. By arranging the worm gear 31 on the side of the bearing plate 12 facing away from the second sliding plate 22 and the top end of the worm gear 31 protruding out of the top wall of the cavity 1211, the top end of the worm gear 31 protrudes out of the top surface of the treatment bed 11, so as to facilitate manual control of the rotation of the worm gear 31.

[0055] In this embodiment: a first rotating rod 33 is provided at one end of the worm wheel 31 outside the cavity 1211. One end of the first rotating rod 33 is fixedly connected to the worm wheel 31, and the other end extends radially away from the worm 32 along the worm wheel 31. Moreover, the radius value of the worm wheel 31 is smaller than the length dimension value of the first rotating rod 33.

[0056] A lever structure is formed by the first rotating rod 33 and the worm wheel 31. The first rotating rod 33 is the power arm, the worm wheel 31 is the resistance arm, and the midpoint of the worm wheel 31 is the fulcrum. Also, the length of the first rotating rod 33 is the length of the power arm, and the radius of the worm wheel 31 is the length of the resistance arm. By setting the radius value of the worm wheel 31 to be smaller than the length dimension value of the first rotating rod 33, a labor-saving lever structure is formed. Therefore, only a relatively small force needs to be applied to the end of the first rotating rod 33 away from the worm wheel 31 to drive the rotation of the worm 32, that is, to drive the first slide plate 21 to slide within the first chute 121, and the operation is simple and labor-saving.

[0057] In this embodiment: the edge of one end of the bearing plate 12 facing the second slide plate 22 is rounded, and it abuts against the second slide plate 22 through the rounded surface.

[0058] By rounding the edge of one end of the bearing plate 12 facing the second slide plate 22, when the second slide plate 22 moves following the first slide plate 21, the second slide plate 22 slides while abutting against the rounded surface, making the rotation of the second slide plate 22 on the first slide plate 21 smoother and improving the comfort of the patient.

[0059] In this embodiment: the bottom surface of the treatment bed 11 is fixedly connected to a support plate 111, and the outer contour edge of the support plate 111 protrudes beyond the outer contour edge of the treatment bed 11;

[0060] A limiting groove 112 is formed at the edge of one end of the top surface of the support plate 111. One end of the second slide plate 22 away from the first slide plate 21 is inserted into the limiting groove 112, and there is a gap between the outer wall of the second slide plate 22 and the side wall of the limiting groove 112.

[0061] During use, when the patient needs to get off the treatment bed 11 after the heat therapy is over, the first rotating rod 33 is rotated in the reverse direction. The first rotating rod 33 pushes the first sliding plate 21 away from the main body 13 of the heat therapy machine through the worm wheel 31 and the worm 32. That is, the second sliding plate 22 is pushed by the first sliding plate 21 to move on the bearing plate 12. When the second sliding plate 22 moves to the rounded corner surface, under the action of the gravity of the second sliding plate 22 and the pressure of the patient's leg, the second sliding plate 22 rotates and tilts on the first sliding plate 21. As the first sliding plate 21 continuously moves away from the main body 13 of the heat therapy machine, the tilt angle of the second sliding plate 22 gradually increases until one side of the second sliding plate 22 facing away from the first sliding plate 21 is inserted into the limiting groove 112 and abuts against the support plate 111. The limiting groove 112 hinders the second sliding plate 22 from freely rotating on the first sliding plate 21, so that the second sliding plate 22 maintains a stable tilted state, facilitating the patient to stand up and step off the footrest plate 23, and providing convenience for the patient to get off the treatment bed 11.

[0062] In this embodiment: There are two footrest plates 23, and the two footrest plates 23 are arranged in sequence along the sliding direction of the first sliding plate 21;

[0063] Both of the two footrest plates 23 are slidably matched with the second sliding plate 22 and can approach or move away from each other by sliding. And an adjusting component for adjusting the distance between the two footrest plates 23 is arranged on the second sliding plate 22.

[0064] In this embodiment: The outer dimension of one footrest plate 23 facing the first sliding plate 21 is smaller than that of the other footrest plate 23, and the outer contour edge of the footrest plate 23 facing away from the first sliding plate 21 protrudes from the outer contour edge of the other footrest plate 23.

[0065] A two - stage step structure is formed by the two footrest plates 23 and the second sliding plate 22. The two footrest plates 23 are respectively slidably connected to the second sliding plate 22, and the distance between the two footrest plates 23 is adjusted through the adjusting component, that is, the height difference of the steps is adjusted, further providing convenience for the patient to climb onto the treatment bed 11; by making the outer contour edge of the footrest plate 23 facing away from the first sliding plate 21 protrude from the outer contour edge of the other footrest plate 23, it is convenient for the patient to step on the two footrest plates 23 stably.

[0066] In this embodiment: Two grooves 231 are formed on the surface of one footrest plate 23 facing the first sliding plate 21 and away from the other footrest plate 23, and the outer contours of the two grooves 231 are both in the shape of an imitation foot sole.

[0067] A groove 231 is formed on a footrest plate 23 facing the first slide plate 21. The patient steps on the sole of the foot into the groove 231 to perform a preliminary positioning of the patient's body. At the same time, the groove 231 restricts the free sliding of the patient's foot on the corresponding footrest plate. During the movement of the first slide plate 21 driving the second slide plate 22, the relative position of the patient's foot and the second slide plate 22 remains unchanged, enabling the patient to move smoothly following the first slide plate 21 and the second slide plate 22.

[0068] In this embodiment: A guiding groove 221 extending towards the first slide plate 21 is formed on a side surface of the second slide plate 22 facing away from the bearing plate 12. The adjusting assembly includes a lead screw 42 parallel to the guiding groove 221, and two sliders 41 respectively fixedly connected to the two footrest plates 23.

[0069] Both ends of the lead screw 42 are respectively inserted into and rotatably fitted with the inner sides of the two side walls along the length direction of the guiding groove 221. And one end of the lead screw 42 facing the first slide plate 21 penetrates through the side wall of the guiding groove 221 and extends out of the guiding groove 221. Two sections of external threads are formed at both ends of the lead screw 42. The thread pitches of the two sections of external threads are the same, and the thread pitch of the section of external thread facing the first slide plate 21 is twice that of the other section of external thread.

[0070] Both of the two sliders 41 are embedded in the guiding groove 221 and are slidably fitted. And the two sliders 41 are respectively strung on both ends of the lead screw 42 and are connected by thread fit.

[0071] During the use process, when it is necessary to reduce the distance between the two footrests, the lead screw 42 is rotated forward. The lead screw 42 pushes the two sliders 41 and the corresponding two footrest plates 23 to slide in the guiding groove 221 along the direction away from the first slide plate 21. Since the thread pitch of the section of external thread of the lead screw 42 facing the first slide plate 21 is twice that of the other section of external thread, that is, the moving speed of the footrest facing the first slide plate 21 is twice that of the other footrest, enabling the two footrests to converge and gather during the process of sliding away from the first slide plate 21, reducing the distance between the two footrest plates 23, that is, reducing the height difference between the two steps, providing convenience for the patient to step and climb.

[0072] Among them, the specific model of the hyperthermia machine main body 13 is Hanfei Medical CRS2280E.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
