Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to a radiotherapy positioning device capable of improving comfort. Background Art

[0002] Radiotherapy is one of the three major means of treating cancer. The premise for its successful implementation is to ensure that the patient's body position is accurately fixed, that is, radiotherapy positioning, so as to ensure the accuracy of treatment. At present, radiotherapy positioning mainly uses a flat bed with a body frame placed on it. Vacuum pads, integrated membranes, head, neck and shoulder masks and other personalized fixing devices are made on the body frame to fix the patient's position. During the production process, patients usually become nervous due to factors such as tight positioning time, insufficient communication, blindness to positioning processes and methods, and various special body position requirements (such as raising both hands and needing to take off most clothes). Nervous emotions will cause the body to be unable to completely relax. The completion of the phantom production in this state is different from the relaxed and familiar state of subsequent patients after multiple exposures to radiotherapy, which is easy to cause large body position deviations and affect the accuracy of radiotherapy. Therefore, how to make the patient completely relax the body is a key factor in the phantom production stage.

[0003] At present, the current method of letting patients relax their bodies is usually subjective explanation and guidance by staff. However, due to various factors such as tight positioning time, insufficient communication, and patients' own reasons, the relaxation effect of most patients is not very good. It is often the case that the physiological curvature of the patient's back and lumbar spine cannot fit well with the vacuum pad, which affects the positioning accuracy. At present, there is no external measure to improve the patient's positioning comfort and reduce the patient's body tension. Therefore, it is urgent to improve. Utility Model Content

[0004] In order to improve the problem that there are no good measures to improve the comfort of radiotherapy positioning during the current radiotherapy process to reduce the patient's body tension and reduce body position deviation, the present application provides a radiotherapy positioning device that can improve comfort.

[0005] The present application provides a radiotherapy positioning device that can improve comfort by adopting the following technical solutions:

[0006] A radiotherapy positioning device capable of improving comfort comprises a bed body and a bed board, wherein the bed board is provided with a long groove along its length direction and at least one transverse groove along its width direction, wherein the long groove is connected to the transverse groove and the two are arranged vertically;

[0007] The bed board has a plurality of bags filled with fluid medium arranged in a matrix in the long grooves and the transverse grooves, and a control system for individually controlling the vibration of each bag is provided on the bed body.

[0008] Furthermore, the long groove is located on the midline of the transverse groove in the length direction.

[0009] Furthermore, the number of the transverse grooves is one, two or three, and when the number of the transverse grooves is two or three, the distance between at least one pair of adjacent two transverse grooves is adapted to the average length from the shoulder to the waist of the human body.

[0010] Furthermore, in the initial state, the upper end surface of the bag is flush with the upper end surface of the bed board;

[0011] When the bag is controlled by the control system to vibrate, the upper end surface of the bag protrudes from the upper end surface of the bed board.

[0012] Furthermore, the control system comprises:

[0013] a catheter connected to a single balloon;

[0014] a valve, disposed on the conduit;

[0015] A pump body connected to the plurality of conduits;

[0016] A controller is electrically connected to the pump body and the valve.

[0017] Furthermore, a heating device is provided between the pump body and the catheter connecting portion.

[0018] Furthermore, the upper surface of the bed board is provided with a plurality of fixing holes for fixing the radiotherapy mold.

[0019] Furthermore, a base is provided under the bed, and a linear drive component for driving the bed to rise and fall is provided on the base, and the linear drive component is connected to a control component.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By controlling the inflation and deflation of multiple bags through the control system, the bag matrix can achieve a slight vibration massage effect on the patient's body, which can relax the patient's body and better adapt to the radiotherapy phantom production. When the patient undergoes multiple radiotherapy treatments, the body position deviation can be effectively controlled to ensure the accuracy of radiotherapy. Moreover, after the patient's limbs are relaxed, the control system can control the inflation volume of each bag individually, so that the bag matrix can fit well with the patient's back, especially the patient's waist and coccyx, which can greatly ensure the accuracy of radiotherapy positioning.

[0022] 2. By setting up multiple transverse grooves, the capsule matrix can cover the patient's shoulders, kidneys, pelvis, coccyx and other parts that need to be relaxed as much as possible, which helps to improve the comfort of the patient lying on the radiotherapy positioning device, and then allow the patient's body to relax more comprehensively, to ensure that the body position deviation can be effectively controlled during multiple radiotherapy sessions.

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2The embodiment of the present application discloses a radiotherapy positioning device capable of improving comfort, comprising a bed body 1 and a bed board 2. The bed board 2 is arranged in the shape of a long board, and is provided with a long groove 21 arranged along its length direction and at least one transverse groove 22 arranged along its width direction. The long groove 21 is connected to the transverse groove 22 and the two are arranged vertically; the long groove 21 is arranged in the center of the bed board 2, and its width is not less than 30 cm, and the width of the transverse groove 22 is not less than 10 cm.

[0034] The bed board 2 has a plurality of bags 3 filled with a fluid medium arranged in a matrix in the long grooves 21 and the transverse grooves 22. A control system for individually controlling the vibration of each bag 3 is provided on the bed body 1. The fluid medium in the bag 3 can be air or water. In the present embodiment, the fluid medium is set to air.

[0035] Specifically, refer to Figure 1 and Figure 2 The long groove 21 is located on the midline of the length direction of the transverse groove 22, and the number of the transverse grooves 22 is one, two or three, and when the number of the transverse grooves 22 is two or three, the distance between at least one pair of adjacent transverse grooves 22 is adapted to the average length from the shoulder to the waist of the human body. When the patient lies on the bed board 2, the bag 3 matrix in the transverse groove 22 can act on the patient's shoulders, kidneys, pelvis, coccyx and other parts that need to be relaxed, while the long groove 21 acts on the patient's entire spine.

[0036] Thus, after the patient to be radiotherapy lies on the bed board 2 of the present application, he mainly lies in the area corresponding to the long groove 21 and the transverse groove 22, and his shoulder area corresponds to one group of transverse grooves 22. At this time, the matrix of bags 3 in the long groove 21 and the transverse groove 22 is in contact with the patient's back. By controlling the inflation and deflation of multiple bags 3 by the control system, a slight vibration massage effect of the bag 3 matrix on the patient's body can be achieved, which can improve the comfort of the patient lying on the radiotherapy positioning device, so that the patient's body can relax more naturally, and thus better adapt to the radiotherapy phantom production, and can effectively control the body position deviation during multiple radiotherapy, and ensure the accuracy of radiotherapy. Moreover, after the patient's limbs are relaxed, the control system can control the inflation amount of each bag 3 individually, so that the bag 3 matrix can fit well with the patient's back, especially the patient's waist and coccyx, which can greatly ensure the positioning accuracy.

[0037] Moreover, the upper end surface of the bladder 3 is flush with the upper end surface of the bed board 2 in the initial state; when the bladder 3 is controlled by the control system to vibrate, its upper end surface protrudes from the upper end surface of the bed board 2. That is, after the bladder 3 is completely deflated, it can maintain the same horizontal height as the bed board 2, and after being inflated, it is higher than the upper end surface of the bed board 2, which can ensure the flatness of the matrix of the bed board 2 and the bladder 3, thereby improving the repeatability of the positioning during treatment.

[0038] And, refer to Figure 1The control system includes a conduit 41 connected to a single bag 3, a valve 42 disposed on the conduit 41, a pump body 43 connected to multiple conduits 41, and a controller 44 electrically connected to the pump body 43 and the valve 42, wherein the pump body 43 is an air pump and the valve 42 is a solenoid valve. In this way, by controlling the opening and closing of different valves 42 with the help of the controller 44, the inflation and deflation process of different bags 3 can be realized, thereby realizing the vibration control and inflation positioning control of a single bag 3.

[0039] In addition, a heating device (not shown in the figure) is provided between the pump body 43 and the connecting part of the catheter 41, and a plurality of fixing holes (not shown in the figure) for fixing the radiotherapy mold are provided on the upper end surface of the bed plate 2; the heating device can heat the fluid medium flowing in the catheter 41, so that the bag 3 can also apply hot compress to the patient's limbs with the help of the warm fluid medium while massaging and relaxing the patient's body, which can further improve the relaxation effect of the present application on the patient. The fixing holes facilitate the fixing of the radiotherapy mold and are conducive to the radiotherapy operation.

[0040] And, refer to Figure 1 and Figure 3 A base 11 is also provided under the bed body 1, and a linear drive member 12 for driving the bed body 1 to rise and fall is provided on the base 11. The linear drive member 12 is connected to a control component. The linear drive member 12 can be a linear motor, or a screw slider structure driven by a motor, or a hand-cranked lifting structure. Its structure is conventional technology and will not be repeated here.

[0041] The implementation principle of a radiotherapy positioning device that can improve comfort in the embodiment of the present application is:

[0042] After the patient to be radiotherapy lies on the bed board 2 of the present application, he mainly lies in the area corresponding to the long groove 21 and the transverse groove 22, and his shoulder area corresponds to one group of transverse grooves 22. At this time, the matrix of bags 3 in the long groove 21 and the transverse groove 22 is in contact with the patient's back. By controlling the inflation and deflation of multiple bags 3 by the control system, the slight vibration massage effect of the bag 3 matrix on the patient can be achieved, which can improve the comfort of the patient lying on the radiotherapy positioning device, so that the patient's body can relax more naturally, and thus better adapt to the radiotherapy phantom production, and can effectively control the body position deviation during multiple radiotherapy, and ensure the accuracy of radiotherapy. Moreover, after the patient's limbs are relaxed, the control system can control the inflation amount of each bag 3 individually, so that the bag 3 matrix can fit well with the patient's back, especially the patient's waist and coccyx, which can greatly ensure the positioning accuracy.

[0043] 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 it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
