Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a radiation protection device for radiotherapy. Background Technology

[0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes alpha, beta, and gamma rays produced by radioactive isotopes, as well as X-rays, electron beams, proton beams, and other particle beams produced by various X-ray therapy machines or accelerators. Approximately 70% of cancer patients require radiation therapy during cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiation therapy in tumor treatment are becoming increasingly prominent, and it has become one of the main means of treating malignant tumors. The efficacy of radiation therapy depends on radiosensitivity. Different tissues and organs, as well as various tumor tissues, show different degrees of change in response after being irradiated. Radiosensitivity is related to the proliferation cycle and pathological grade of tumor cells. That is, cells with active proliferation are more sensitive than cells that do not proliferate. The higher the degree of cell differentiation, the lower the radiosensitivity, and vice versa.

[0003] Radiotherapy plays a wide and important role in the field of tumor treatment. However, existing radiotherapy equipment requires patients to lie on a mobile bed and then be covered with a protective suit over the area not being treated. However, the protective effect of the protective suit is still significantly different from that of a protective shield. The material and rigidity of the protective shield are better than those of the protective suit. Due to the different locations of the radiotherapy, the treatment position needs to be adjusted. The traditional protective shield is inconvenient to use and cannot be effectively adjusted and controlled.

[0004] When applying for this invention, the applicant, through a search, discovered a Chinese patent disclosing a "radiotherapy protective device" with application number "202410518386.9". This patent mainly addresses the issue that regardless of the direction or angle of the radiotherapy machine head, the rotating radiation shield can accurately follow it, ensuring that the radiotherapy port is always aligned with the radiation emission direction of the radiotherapy machine head. In this invention, the rotating radiation shield can follow the movement of the radiotherapy machine head in real time. Combined with the use of a radiation protection suit, this ensures that the non-treatment areas of the patient are always covered by the radiation shield, effectively avoiding the risk of the radiation range expanding due to collimator failure or other equipment malfunctions in external beam radiotherapy equipment. However, this method has limitations for radiotherapy locations larger than the diameter or not located at the specified position. Therefore, based on the applicant's invention, a radiotherapy protective device has been developed that solves the problem that while the material and hardness of the protective shield are better than protective suits, the traditional protective shield is inconvenient and cannot be effectively adjusted and controlled due to the different radiotherapy locations. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a radiation therapy protective device that solves the problems of traditional protective shields being inconvenient to use and unable to be effectively adjusted and controlled due to the different locations of radiation therapy, even though the material and hardness of the protective shield are better than those of protective clothing.

[0009] As a preferred technical solution of the present invention: the interior of the mobile bed is provided with an arc-shaped storage groove, and the arc-shaped storage groove and the strip-shaped opening are connected through each other.

[0010] As a preferred technical solution of the present invention: both sides of one end of the movable bed are threadedly connected with adjusting screws, one end of the adjusting screws abuts against the protective cover, the bottom end of the support frame is fixedly connected with a support base plate, one end of the support frame is fixedly connected with a drive motor, and the drive end threaded rod of the drive motor is fixedly connected.

[0011] As a preferred embodiment of the present invention: the limiting component includes a supporting spring and an arc-shaped triangular block, one end of the supporting spring is fixedly connected to an abutment plate, one side of the abutment plate is fixedly connected to a plurality of supporting rods, and the end of the supporting rod away from the abutment plate is fixedly connected to an arc-shaped triangular block.

[0012] As a preferred technical solution of the present invention: one end of the protective cover is fixedly connected to a limiting base plate, and the limiting base plate and the arc-shaped triangular block are in contact and cooperate.

[0013] As a preferred technical solution of the present invention: several square slots are provided on both sides of the inner side of the strip-shaped opening, a limiting plate is inserted into the inner side of the square slots, a control panel is fixedly connected to one side of the radiotherapy instrument, and anti-slip texture is provided on the upper surface of the telescopic protective plate.

[0014] Beneficial effects This invention provides a radiation protection device for radiotherapy. It has the following beneficial effects: This invention comprises a protective cover, an arc-shaped storage groove, a strip-shaped opening, and an arc-shaped triangular block. When the patient lies flat on the upper surface of the bed board, the protective cover is rotated to create the arc-shaped storage groove, which extends through the strip-shaped opening and mates with the strip-shaped opening on the other side. At this time, the diameter of the limiting base plate is larger than the strip-shaped opening, which can play a limiting role. The arc-shaped triangular block plays a supporting role, thus supporting the protective cover. The protective cover is positioned in a semi-circular arc on the upper surface of the patient, achieving a protective effect. This structure can fully protect the patient's overall safety during diagnosis and treatment.

[0015] This invention comprises a telescopic protective plate, a locking through hole, a rubber cone, and an arc-shaped storage groove. The telescopic protective plate slides against the anti-slip texture on its surface at the required radiotherapy location, thereby disengaging the locking through hole and the rubber cone, completing the disassembly process. The locking through hole can then slide into the arc-shaped storage groove for arc-shaped storage. At this point, the center of the protective cover is open, facilitating radiotherapy operations at the designated radiotherapy location.

[0016] This invention comprises a protective cover, a limiting plate, and a square slot. When the radiotherapy location is large or at the junction of two protective covers, the protective cover can slide to insert the limiting plate into the square slot, thereby limiting the contact of the protective covers on both sides and exposing the radiotherapy location.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-7As shown, this embodiment of the invention provides a radiation therapy protective device, including a support frame 1. A slide rod 103 is fixedly connected to one side of the inside of the support frame 1, and a threaded rod 104 is rotatably connected to the other side of the inside of the support frame 1. A movable bed 2 is threadedly connected to one end of the threaded rod 104. The movable bed 2 and the slide rod 103 are slidably engaged. Both sides of the top of the movable bed 2 have strip-shaped openings 202. Several protective covers 3 are rotated inside the strip-shaped openings 202. When the patient lies flat on the upper surface of the bed board 201, the protective covers 3 are rotated to create an arc-shaped storage groove 204, which extends out through the strip-shaped openings 202, thus housing the protective covers 3. The radiation is directed at the patient's upper surface in a semi-circular arc to achieve a protective effect. One end of the support frame 1 is equipped with a radiotherapy device 4. The movable bed 2 passes through the interior of the radiotherapy device 4. The interior of the protective cover 3 has an arc-shaped opening groove 304. Both sides of the arc-shaped opening groove 304 and the interior of the protective cover 3 have sliding grooves 302. The sliding grooves 302 are fitted with telescopic protective plates 301. A limit component 5 is provided on the upper side of one side of the movable bed 2. A bed board 201 is fixedly connected to the upper surface of the movable bed 2. The patient lies flat on the upper surface of the bed board 201, and then the protective cover 3 is used according to the required position of the radiotherapy.

[0022] In a preferred embodiment: a female groove 305 is provided on one side of the protective cover 3, and a protrusion 306 is fixedly connected to the other side of the protective cover 3. The female groove 305 and the protrusion 306 are inserted and engaged. During the extrusion process, the female groove 305 on one side of the protective cover 3 and the protrusion 306 on the other side engage to complete the secure insertion.

[0023] In a preferred embodiment: a locking through hole 308 is provided at the middle of one end of the telescopic protective plate 301. The locking through hole 308 can slide into the interior of the arc-shaped storage groove 204 to complete the arc-shaped storage. At this time, the middle of the protective cover 3 is in an open state, which facilitates the radiation operation at the designated radiotherapy position. A rubber cone 307 is fixedly connected to the inner wall of the protective cover 3 and at the middle of one end of the arc-shaped opening groove 304. A rubber ring is fixedly connected to the end of the rubber cone 307. The rubber ring and the locking through hole 308 are inserted and matched.

[0024] In a preferred embodiment: the interior of the movable bed body 2 is provided with an arc-shaped storage groove 204. When the protective cover 3 is rotated, the arc-shaped storage groove 204 is rotated out and extends out through the strip opening 202, which cooperates with the strip opening 202 on the other side. When the protective cover 3 extends out of the strip opening 202, the opening between the arc-shaped storage groove 204 and the strip opening 202 is through.

[0025] In a preferred embodiment: both sides of one end of the movable bed 2 are threaded with adjusting screws 203. By rotating the adjusting screws 203, the multiple protective covers 3 are slidable to achieve compression and fit. One end of the adjusting screw 203 and the protective cover 3 are in contact and cooperate. The bottom end of the support frame 1 is fixedly connected to the support base plate 101. One end of the support frame 1 is fixedly connected to the drive motor 102. The drive motor 102 drives the rotation of the threaded rod 104 to move the movable bed 2 into the interior of the radiotherapy instrument 4 for diagnostic and treatment work. The drive end of the drive motor 102 is fixedly connected to the threaded rod 104.

[0026] In a preferred embodiment: the limiting component 5 includes a support spring 501 and an arc-shaped triangular block 502. One end of the support spring 501 is fixedly connected to an abutment plate 504. When the protective cover 3 pushes the arc-shaped storage groove 204 in force, the force exerted by the worker will be greater than the elastic support force of the support spring 501 on the arc-shaped triangular block 502. Several support rods 503 are fixedly connected to one side of the abutment plate 504. The end of the support rod 503 away from the abutment plate 504 is fixedly connected to the arc-shaped triangular block 502. The limiting base plate 309 presses against the arc-shaped triangular block 502, causing the arc-shaped triangular block 502 to retract. The limiting base plate 309 and the protective cover 3 are flipped back into the arc-shaped storage groove 204 to complete the storage function. The limiting base plate 309 continues to rise and expand in contact with the arc-shaped triangular block 502, and is positioned above the arc-shaped triangular block 502. The arc-shaped triangular block 502 provides support, thus achieving the support function of the protective cover 3.

[0027] In a preferred embodiment: a limiting base plate 309 is fixedly connected to one end of the protective cover 3. The limiting base plate 309 is provided at one end of the protective cover 3. At this time, the diameter of the limiting base plate 309 is larger than that of the strip opening 202, which can play a limiting role and prevent the protective cover 3 from detaching from the overall structure of the strip opening 202. The limiting base plate 309 and the arc-shaped triangular block 502 abut against each other.

[0028] In a preferred embodiment: several square slots 205 are provided on both sides of the inner side of the strip opening 202. A limiting plate 206 is inserted into the inside of the square slots 205. When the radiotherapy position is large or at the junction of two protective covers 3, the limiting plate 206 can be inserted into the square slot 205 by sliding the protective cover 3, thereby abutting and limiting the protective covers 3 on both sides, so that the radiotherapy position is exposed. A control panel 401 is fixedly connected to one side of the radiotherapy instrument 4. The upper surface of the telescopic protective plate 301 is provided with anti-slip texture 303. The anti-slip texture 303 on the surface of the telescopic protective plate 301 abuts and slides, thereby disengaging the locking through hole 308 and the rubber cone 307, completing the disassembly.

[0029] Working principle: During use, the patient lies flat on the upper surface of the bed board 201. The protective cover 3 is then selected based on the location of the radiotherapy. After the patient lies flat on the upper surface of the bed board 201, the protective cover 3 is rotated to create an arc-shaped storage groove 204, which extends through a strip opening 202 and mates with another strip opening 202. When the protective cover 3 extends beyond one side of the strip opening 202, a limiting base plate 309 is provided at one end of the protective cover 3. The diameter of the limiting base plate 309 is larger than that of the strip opening 202, thus limiting the protective cover 3 and preventing it from detaching from the strip opening 202. 02. Overall Structure: Subsequently, the limiting base plate 309 continues to rise and expands in contact with the arc-shaped triangular block 502, positioned above the arc-shaped triangular block 502. The arc-shaped triangular block 502 provides support, thus supporting the protective cover 3. The protective cover 3 is positioned in a semi-circular arc and illuminates the patient's upper surface, achieving a protective effect. Then, by rotating the adjusting screw 203, the multiple protective covers 3 slide, achieving compression and adhesion. During compression, the female groove 305 on one side of the protective cover 3 and the protrusion 306 on the other side engage, completing a secure insertion. The adjusting screw 203 uses threaded contact to achieve firmness. Subsequently, the anti-slip texture 303 on the surface of the telescopic protective plate 301 is slid against the radiotherapy location as needed, thereby disengaging the locking through hole 308 and the rubber cone 307, completing the disassembly. The locking through hole 308 can then slide into the arc-shaped storage groove 204 for arc-shaped storage. At this time, the middle of the protective cover 3 is open, facilitating radiotherapy operations at the designated radiotherapy location. When the radiotherapy location is large or at the junction of two protective covers 3, the protective cover 3 can be slid to insert the limiting plate 206 into the square slot 205, thereby limiting the contact of the protective covers 3 on both sides. The radiotherapy site only needs to be exposed; the drive motor 102 drives the rotation of the threaded rod 104, moving the moving bed 2 into the radiotherapy instrument 4 for diagnosis and treatment. After the operation is completed, the protective cover 3 can be forcefully pushed into the arc-shaped storage groove 204. At this time, the force of the operator will be greater than the elastic support force of the support spring 501 on the arc-shaped triangular block 502. At this time, the limiting base plate 309 squeezes the arc-shaped triangular block 502, the arc-shaped triangular block 502 is retracted, and the limiting base plate 309 and the protective cover 3 are flipped back into the arc-shaped storage groove 204 to complete the storage function.
