Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and more specifically, to a direct-insertion treatment bed for neutron therapy. Background Technology

[0002] Neutron therapy, as a high-energy particle radiotherapy method, has shown significant advantages in the treatment of refractory tumors due to its unique bioavailability. Neutron beams possess high linear energy transfer characteristics, effectively killing hypoxic tumor cells that are insensitive to traditional photon radiotherapy. However, its therapeutic effect is highly dependent on the spatial coupling between the patient's position and the neutron beam path. The smaller the gap between the tumor location and the neutron source, the better the neutron therapy effect; as the distance between the tumor location and the neutron source increases, the neutron beam will be scattered or absorbed in the air, leading to poor treatment results.

[0003] In the prior art, for example, invention patent application CN117064683A discloses an MRI examination bed head support, including a fixed base. The top of the fixed base is provided with a slidable adjustment component and a hinged protective component. The adjustment component includes a first fixed base plate fixedly installed on the top of the fixed base, and the interior of the first fixed base plate is provided with an engaging structure. The protective component includes a support plate fixedly installed on one side of the outer wall of the fixed base, and the top of the support plate is provided with a hinged structure. The adjustment component also includes a movable plate provided on the top of the fixed base, and the top of the movable plate is provided with a rotatable adjustment structure. The adjustment component also includes a second fixed base plate fixedly installed on the top of the fixed base. However, this solution can only adapt to the head-neck distance of different patients by adjusting the depth of the adjustment device. When used for neutron therapy, it cannot adjust the distance between the patient's head and the neutron source. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot adjust the distance between the patient's head and the neutron source, and to provide a direct-insertion treatment bed for neutron therapy. The direct-insertion structure enables the translation of the headrest position, thereby adjusting the distance between the patient's head and the neutron source and improving the accuracy of neutron therapy.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A direct-insertion treatment bed for neutron therapy is provided, comprising a bed board assembly and a headrest assembly, wherein the headrest assembly is movably connected to the bed board assembly along the width direction of the bed board assembly.

[0007] This utility model's direct-insertion treatment bed uses a movable bed board assembly and a headrest assembly. The headrest assembly can be moved along the width of the bed board assembly to adjust the relative position of the bed board assembly and the headrest assembly, thereby adapting to the location of the tumor on the head of different patients, reducing the distance between the patient's head and the neutron source, and bringing the patient's head as close to the neutron source as possible, thus improving the efficiency and precision of neutron therapy.

[0008] Furthermore, the top of the bed board assembly is provided with multiple sets of parallel mounting slots. The headrest assembly is inserted into the mounting slots and detachably connected to the bed board assembly. During use of the treatment bed, the headrest assembly can be inserted into the mounting slots on the top of the bed board assembly. The multiple sets of parallel mounting slots provide multiple mounting positions for the headrest assembly, accommodating different tumor locations on the head of different patients. The direct insertion structure allows for translation of the headrest assembly's position, enabling tumors in different locations to be closer to the neutron source, thereby improving treatment effectiveness.

[0009] Furthermore, the headrest assembly includes a support portion and an insertion portion connected to each other, the insertion portion being detachably connected to the mounting groove. The headrest assembly supports the patient's head through the support portion, keeping the patient's head position unchanged during treatment, while the insertion portion, detachably connected to the mounting groove, is used to fix the relative position between the headrest assembly and the bed board assembly.

[0010] Furthermore, the mounting groove is provided with a threaded hole and a first fastener, the first fastener passing through the threaded hole and abutting against the insertion part. After the insertion part is inserted into the mounting groove, the first fastener is screwed into the threaded hole, causing the first fastener to abut against the insertion part, thereby stably fixing the insertion part in the mounting groove and preventing loosening during neutron therapy.

[0011] Furthermore, the insertion part is provided with an elastic upturned portion, and the mounting groove is provided with a snap-fit ​​hole, the elastic upturned portion abutting against the snap-fit ​​hole. When the insertion part is inserted into the mounting groove, the elastic upturned portion is first compressed until it reaches the snap-fit ​​hole. Under its own elasticity, the elastic upturned portion springs up, thereby abutting against the snap-fit ​​hole, achieving locking of the insertion part in the mounting groove and providing a stable limiting effect. When it is necessary to remove the insertion part from the mounting groove, simply press the elastic upturned portion while moving the insertion part outward to separate the headrest assembly from the bed board assembly.

[0012] Furthermore, the insertion part is provided with a guide chamfer. During use, the position between the headrest assembly and the bed board assembly needs to be repeatedly adjusted, and the insertion part needs to be inserted into the mounting slot multiple times. The guide chamfer on the insertion part facilitates quick alignment of the insertion part with the mounting slot, enabling rapid insertion and thus improving work efficiency.

[0013] Furthermore, it also includes a fixing strap, with fixing strap mounting portions on both sides of the bed board assembly, and both ends of the fixing strap connected to the fixing strap mounting portions respectively. The fixing strap is connected to the fixing strap mounting portions on both sides of the bed board assembly, thereby fixing the patient's body position and preventing them from slipping or tipping over from the operating table during treatment.

[0014] Furthermore, it also includes a support plate and a support pad, the support plate being perpendicular to the bed board assembly, and the support pad being detachably connected to the bed board assembly. During treatment, the patient sometimes needs to lie on their side on the treatment bed. At this time, the support pad and support plate work together to provide support for the patient. Since the support pad and bed board assembly are detachably connected, the position of the support pad can be adjusted to accommodate the patient's side position, regardless of which side they are lying on, thereby achieving stable support and improving comfort.

[0015] Furthermore, the support pad is shaped like a ramp, and the bed board assembly is provided with an installation strip. The installation strip has a locking block for engaging with the support pad. The locking block on the installation strip engages with the support pad, thereby fixing the support pad in position on the bed board assembly. The ramp-shaped support pad provides support for the patient lying on their side through its ramp. When the patient changes their lying position, the support pad can be directly removed from the installation strip, flipped over, and then reinstalled on the opposite side.

[0016] Furthermore, the support pad is equipped with a detachable handle, which is I-shaped. The support pad is relatively large, and the gripping and handling process remains unchanged. The I-shaped handle makes it easier for medical staff to pick it up and install it onto the treatment bed. After installation, the handle can be detached to avoid affecting the patient's side-lying position.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By bringing the patient's head closer to the neutron source, the distance between the patient's tumor center and the neutron source is reduced, thereby improving the effectiveness and precision of neutron therapy;

[0019] 2. It helps to fix the patient's position on the treatment bed, preventing the patient from slipping while tilting their body. Attached Figure Description

[0029] Example 1

[0030] This embodiment is a first embodiment of a direct-insertion treatment bed for neutron therapy, including a bed board assembly 100 and a headrest assembly 200, wherein the headrest assembly 200 is movably connected to the bed board assembly 100 along the width direction of the bed board assembly 100.

[0031] like Figure 1 , Figure 2As shown, the direct-insertion treatment bed in this embodiment allows the headrest assembly 200 to be moved along the width of the bed board assembly 100, adjusting the relative position of the bed board assembly 100 and the headrest assembly 200. This adapts to different tumor locations on the patient's head, reducing the distance between the patient's head and the neutron source, bringing the patient's head as close to the neutron source as possible, and improving the efficiency and precision of neutron therapy. In this embodiment, the headrest assembly 200 and the bed board assembly 100 can be slidably connected by a slide rail, or multiple locking slots can be provided in the width direction for locking, both of which allow for adjustment of the relative position and reduce the distance between the tumor location and the neutron source.

[0032] like Figure 2 As shown, the top of the bed board assembly 100 is provided with multiple sets of parallel mounting slots 110. The headrest assembly 200 is inserted into the mounting slots 110 and detachably connected to the bed board assembly 100. During use of the treatment bed, the headrest assembly 200 can be inserted into the mounting slots 110 on the top of the bed board assembly 100. The mounting slots 110 are provided in multiple sets and are parallel to each other, providing multiple installation positions for the headrest assembly 200, thereby adapting to the different tumor positions of different patients. The direct insertion structure enables the translation of the headrest assembly 200, allowing tumors in different positions to be closer to the neutron source, thereby improving the treatment effect.

[0033] like Figure 6 As shown, the headrest assembly 200 includes a support portion 210 and an insertion portion 220 connected to each other. The insertion portion 220 is detachably connected to the mounting groove 110. The headrest assembly 200 supports the patient's head through the support portion 210, keeping the patient's head position unchanged during treatment. The insertion portion 220 is detachably connected to the mounting groove 110 to fix the relative position between the headrest assembly 200 and the bed board assembly 100.

[0034] The mounting slot 110 has a threaded hole and a first fastener 111, which passes through the threaded hole and abuts against the insertion part 220. Figure 4 , Figure 5 As shown, after the insertion part 220 is inserted into the mounting groove 110, the first fastener 111 is screwed into the threaded hole, so that the first fastener 111 abuts against the insertion part 220, thereby stably fixing the insertion part 220 in the mounting groove 110 and preventing loosening during neutron therapy.

[0035] The insertion part 220 is provided with a flexible protruding part 221, and the mounting groove 110 is provided with a snap-fit ​​hole 112, the flexible protruding part 221 abutting against the snap-fit ​​hole 112. Figure 6As shown, the insertion part 220 is inserted into the mounting groove 110. The elastic protruding part 221 is first compressed until it reaches the snap-fit ​​hole 112. The elastic protruding part 221 bounces up under its own elasticity, thereby abutting against the snap-fit ​​hole 112, realizing the locking of the insertion part 220 in the mounting groove 110 and providing a stable limiting effect. When it is necessary to remove the insertion part 220 from the mounting groove 110, simply press the elastic protruding part 221 and move the insertion part 220 outward to separate the headrest assembly 200 from the bed board assembly 100.

[0036] The insertion part 220 is provided with a guide chamfer 222. During the use of the treatment bed with the direct insertion structure, it is necessary to repeatedly adjust the position between the headrest assembly 200 and the bed board assembly 100, and insert the insertion part 220 into the mounting slot 110 multiple times. The guide chamfer 222 on the insertion part 220 makes it easier for the user to quickly align the insertion part 220 with the mounting slot 110 and insert it quickly, thereby improving work efficiency.

[0037] The working principle of the direct-insertion treatment bed for neutron therapy in this embodiment is as follows: The multiple sets of parallel mounting slots 110 on the top of the bed board assembly 100 cooperate with the detachable headrest assembly 200 to achieve precise positioning and adjustment. After the insertion part 220 of the headrest assembly 200 is quickly aligned and inserted into the selected mounting slot 110 with the help of the guide chamfer 222, the elastic raised part 221 and the snap-fit ​​hole 112 elastically snap together to form a primary limit. At the same time, the first fastener 111 in the threaded hole is tightened to achieve secondary mechanical fixation. The double locking mechanism ensures the stability of the treatment process. The support part 210 adjusts the distance between the patient's head and the neutron source to the optimal treatment distance by relying on the multi-slot translation function, which keeps the head stable and achieves precise positioning. The direct-insertion structure significantly improves the efficiency and ease of operation of neutron therapy.

[0038] Example 2

[0039] This embodiment is a second embodiment of a direct-insertion treatment bed for neutron therapy. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 2 , Figure 3 As shown, both the support portion 210 and the bed board assembly 100 are equipped with diaphragm fixing buckles 230, and the diaphragm fixing buckles 230 are equipped with diaphragm mounting grooves 231. During neutron therapy, it is necessary to fix the patient's head position so that the neutron beam can accurately reach the tumor location. Therefore, thermoplastic positioning diaphragms are often used to cover the patient's head. Diaphragm fixing buckles 230 are provided on both the support portion 210 and the bed board assembly 100, and the diaphragm is installed in the diaphragm mounting grooves 231 to fix the position of the patient's head, neck, and shoulders, preventing displacement during treatment.

[0040] It also includes a fixing strap 120, and the bed board assembly 100 has fixing strap mounting parts 130 on both sides. The two ends of the fixing strap 120 are respectively connected to the fixing strap mounting parts 130. The fixing strap 120 is connected to the fixing strap mounting parts 130 on both sides of the bed board assembly 100, thereby fixing the position of the patient's body and preventing him from slipping or tipping off the operating table during treatment.

[0041] The working principle of the direct-insertion treatment bed for neutron therapy in this embodiment is as follows: the membrane fixing buckles 230 on the surface of the support part 210 and the bed board assembly 100 achieve three-dimensional shaping and wrapping of the patient's head, neck and shoulders by embedding thermoplastic positioning membranes; at the same time, the fixing straps 120 on both sides of the bed board assembly 100 are connected to the elastic fixing straps 120 to form a trunk restraint protection to prevent slippage during treatment.

[0042] Example 3

[0043] This embodiment is a second embodiment of a direct-insertion treatment bed for neutron therapy. Similar to the first embodiment, it includes a support plate 140 and a support pad 150. The support plate 140 is perpendicular to the bed board assembly 100, and the support pad 150 is detachably connected to the bed board assembly 100. During treatment, the patient sometimes needs to lie on their side on the treatment bed. In this case, the support pad 150 and the support plate 140 work together to provide support. Since the support pad 150 is detachably connected to the bed board assembly 100, the position of the support pad 150 can be adjusted to accommodate the patient's lying position, regardless of which side they are facing, thus achieving stable support and improving comfort. In this embodiment, one support pad 150 can be placed on each side of the patient's body, and their sizes can differ. The two support pads 150, one large and one small, provide support to the patient's body simultaneously from both sides, improving the fixation effect.

[0044] In this embodiment, the support pad 150 is shaped like a ramp. The bed board assembly 100 is provided with an installation strip 170, and the installation strip 170 is provided with a snap-fit ​​block 171 for engaging with the support pad 150. The snap-fit ​​block 171 on the installation strip 170 engages with the support pad 150, thereby fixing the support pad 150 in the position of the bed board assembly 100. The ramp-shaped support pad 150 provides support for the patient lying on their side through its ramp. When the patient changes their lying position, the support pad 150 can be directly removed from the installation strip 170, flipped over, and then reinstalled on the opposite side.

[0045] like Figure 1 As shown, the support pad 150 is equipped with a detachable handle 151, which is I-shaped. The support pad 150 is relatively large in size, and the grasping and carrying process remains unchanged. The I-shaped handle 151 on the support pad 150 makes it easy for medical staff to pick it up and install it on the treatment bed. After installation, the handle 151 can be removed to avoid affecting the patient's side lying.

[0046] like Figure 3 , Figure 5 As shown, the bed board assembly 100 is provided with an adjustment part 160, which has multiple sets of adjustment holes 161 and second fasteners 162. The second fasteners 162 pass through the adjustment holes 161 and are connected to the support plate 140. The second fasteners 162 are mainly used to fix the position of the support plate 140 on the bed board assembly 100. By loosening the second fasteners 162, the bed board assembly 100 can be moved along the adjustment part 160. After moving to the appropriate position of the adjustment hole 161, the second fasteners 162 are installed into the adjustment hole 161 and connected to the support plate 140, thereby adapting to different patient body shapes and side-lying positions.

[0047] The working principle of the direct-insertion treatment bed for neutron therapy in this embodiment is as follows: the multi-hole position adjustment part 160 on the bed board assembly 100 cooperates with the second fastener 162 to realize the lateral sliding and locking of the support plate 140. Combined with the detachable "one large and one small" inclined platform-shaped support pads 150 on the left and right sides, an asymmetrical support surface is formed, which accurately matches the trunk curve of the patient when lying on his side. The support pad 150 has an I-shaped handle 151 built in it to realize quick disassembly and assembly. After installation, it can be removed to avoid interfering with the body position, thus meeting the optimization of patient stability under supine and lateral multi-mode treatment.

[0048] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
