Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an adjustable fixation device for SPECT alpha nuclide imaging. Background Technology

[0002] SPECT (Single Photon Emission Tomography) alpha nucleoside imaging technology is an important tool for accurate disease diagnosis in the field of medical imaging, and is widely used in the detection and evaluation of diseases such as tumors and cardiovascular diseases. This technology has extremely high requirements for stability during the imaging process. Patient movement can easily lead to blurred images and increased artifacts, which in turn affects the doctor's accurate judgment of the location, size, and shape of lesions. Therefore, it is necessary to effectively restrain the patient's body through a fixation device during the examination.

[0003] In existing technologies, common adjustable fixation devices used for SPECT alpha radionuclide imaging require guiding the patient to lie flat on top of the examination table before using elastic restraint straps to wrap around the patient's body and fix them in place, thus restricting the patient's voluntary movement. However, the tightness of the restraint straps largely depends on the experience and judgment of medical staff. If the straps are too loose, the patient's position may shift, affecting image quality; if they are too tight, they may cause pressure injuries to the patient, especially for special patients such as those who are comatose or children who cannot express their discomfort, posing a higher risk. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an adjustable fixation device for SPECT alpha radionuclide imaging. This addresses the issue that the tightness of the restraints in common adjustable fixation devices for SPECT alpha radionuclide imaging, as mentioned in the background section, mainly relies on the experience and judgment of medical personnel. This can easily lead to patient positional shifts due to excessive looseness, affecting image quality, or cause pressure injuries to the patient due to excessive tightness, especially for special patients such as those who are comatose or children who cannot express their discomfort, posing a higher risk.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: An adjustable fixation device for SPECT alpha nuclide imaging includes:

[0006] Support platform;

[0007] The bed frame is slidably connected to the top of the support platform;

[0008] A movable seat is installed inside the bed. A first connecting seat is provided on one side of the movable seat, and a Velcro fastener is fixedly connected to one side of the first connecting seat. A second connecting seat is provided on the other side of the movable seat. A winding rod is rotatably connected to the second connecting seat through a damping pivot. A restraint strap is fixedly connected to the surface of the winding rod, and an adhesive plate is sleeved on the surface of the restraint strap. A trigger seat is slidably connected inside the second connecting seat. A return spring is fixedly connected between the trigger seat and the second connecting seat. A first alarm is fixedly connected to the inner wall of the second connecting seat, and a second alarm is fixedly connected to the inner wall of the second connecting seat. A third connecting seat is provided on one side of the bed.

[0009] Optionally, guide holes are provided on both sides of the bed, the movable seat is slidably connected to the guide holes, and an adjusting rod is rotatably connected to one side of the movable seat, and the adjusting rod is threadedly connected to the bed.

[0010] Optionally, fixing bolts are installed in the first, second, and third connecting seats, and the fixing bolts are threaded to the movable seat and to the bed.

[0011] Optionally, the inner wall of the second connecting seat is provided with a sliding groove, and the trigger seat and the sliding groove are slidably connected.

[0012] Optionally, the surface of the second connecting seat has a through hole on the outside of the restraint strap, and the edge of the through hole is rounded.

[0013] Optionally, a support plate is fixedly connected to the bottom of the bed, and the support plate is L-shaped.

[0014] Optionally, a first knob is fixedly connected to one end of the winding rod extending out of the second connecting seat, and a second knob is fixedly connected to one end of the adjusting rod extending out of the bed. Both the first knob and the second knob have anti-slip protrusions on their surfaces.

[0015] Optionally, a pillow frame is fixedly connected to the top of the bed frame, and the top of the pillow frame is arc-shaped.

[0016] The beneficial effects of this invention are as follows: Pulling the restraint strap allows it to wrap around the patient and be fixed to the bed surface via an adhesive plate and Velcro, thus restricting the patient's free movement. Rotating the retractor adjusts the tightness of the restraint strap, allowing the device to adapt to patients of different body types. During this process, the tension of the restraint strap can be monitored using a return spring, trigger seat, first alarm, and second alarm, preventing positional shifts due to excessive looseness and pressure injuries due to excessive tightness, thereby improving patient comfort during examination. Furthermore, the second connecting seat, made of non-metallic materials such as plastic, can physically enclose metal components such as the return spring, preventing these components from interfering with imaging.

[0017] The positions of the first and second connecting seats can be adjusted according to the patient's height using the adjusting rod, moving seat, and guide hole, thereby ensuring that the restraint strap can always wrap around the patient's optimal fixation point, further improving the device's applicability to a variety of patients.

[0018] The first, second, and third connecting seats can be removed from the bed frame by rotating the fixing bolts, making it easy to maintain and replace the restraint straps. The fixing bolts are made of non-metallic materials such as plastic. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] Please see Figures 1 to 5 This utility model provides a technical solution: an adjustable fixation device for SPECT alpha nuclide imaging, comprising: a support platform 1; a bed 2 slidably connected to the top of the support platform 1, a movable seat 3 disposed inside the bed 2, a first connecting seat 301 disposed on one side of the movable seat 3, a Velcro 302 fixedly connected to one side of the first connecting seat 301, a second connecting seat 303 disposed on the other side of the movable seat 3, a winding rod 304 rotatably connected inside the second connecting seat 303 via a damping shaft, a restraint strap 305 fixedly connected to the surface of the winding rod 304, an adhesive plate 306 sleeved on the surface of the restraint strap 305, a trigger seat 307 slidably connected inside the second connecting seat 303, a return spring 308 fixedly connected between the trigger seat 307 and the second connecting seat 303, a first alarm 309 fixedly connected to the inner wall of the second connecting seat 303, a second alarm 310 fixedly connected to the inner wall of the second connecting seat 303, and a third connecting seat 311 disposed on one side of the bed 2.

[0032] The patient lies flat on the top of the bed 2. The restraint strap 305 is pulled to wrap around the patient and secured to the bed 2 surface via the adhesive plate 306 and Velcro 302, thus restricting the patient's free movement. The tightness of the restraint strap 305 can be adjusted by rotating the retractor 304, allowing the device to adapt to patients of different body types. During this process, if the restraint strap 305 is too loose, the return spring 308 will cause the trigger seat 307 to contact the first alarm 309, which will sound an alarm indicating that the restraint strap 305 is too loose. If the restraint strap 305 is too tight, the trigger seat 307, due to the pressure from the restraint strap 305, will contact the second alarm 310, which will sound an alarm to remind the patient that the restraint strap 305 is too tight. This monitoring of the restraint strap 305's tightness prevents positional shifts due to looseness and pressure injuries due to excessive tightness, improving patient comfort during examinations. Among them, the second connecting seat 303, which is made of non-metallic materials such as plastic, can physically enclose metal components such as the reset spring 308, thus preventing these components from affecting the imaging.

[0033] Furthermore, the inner wall of the second connecting seat 303 is provided with a sliding groove 3031, and the trigger seat 307 is slidably connected to the sliding groove 3031.

[0035] Furthermore, the surface of the second connecting seat 303 is provided with a through hole 3032 on the outside of the restraint strap 305, and the edge of the through hole 3032 is rounded.

[0036] The edges of the through hole 3032 are rounded to prevent it from causing wear on the binding strap 305.

[0037] Optionally, a pillow frame 4 is fixedly connected to the top of the bed frame 2, and the top of the pillow frame 4 is arc-shaped.

[0038] The pillow frame 4 provides support for the patient's head, which can both fix the head and improve the patient's comfort when lying flat.

[0040] Rotating the adjusting rod 312 will cause the movable seat 3 to slide along the guide hole 201, thereby adjusting the position of the first connecting seat 301 and the second connecting seat 303 according to the patient's height, thus ensuring that the restraint strap 305 can always surround the patient's optimal fixation point, further improving the applicability of the device to diverse patients.

[0041] Please refer to 1 to Figure 3 The present invention provides a technical solution: characterized in that a fixing bolt 313 is provided in the first connecting seat 301, the second connecting seat 303 and the third connecting seat 311, and the fixing bolt 313 is threadedly connected to the movable seat 3 and to the bed body 2, wherein the fixing bolt 313 is made of non-metallic material such as plastic.

[0042] By rotating the fixing bolt 313, the first connecting seat 301, the second connecting seat 303 and the third connecting seat 311 can be removed from the bed 2, which facilitates the maintenance and replacement of the restraint belt 305.

[0043] Furthermore, a support plate 202 is fixedly connected to the bottom of the bed body 2, and the support plate 202 is L-shaped.

[0044] The support plate 202 can provide additional support to one end of the bed body 2, thereby preventing the bed body 2 from deforming.

[0045] Optionally, a first knob 3041 is fixedly connected to one end of the winding rod 304 extending out of the second connecting seat 303, and a second knob 3121 is fixedly connected to one end of the adjusting rod 312 extending out of the bed body 2. Both the first knob 3041 and the second knob 3121 are provided with anti-slip protrusions.

[0046] The first knob 3041 facilitates the rotation of the winding rod 304, and the second knob 3121 facilitates the rotation of the adjusting rod 312. Both the first knob 3041 and the second knob 3121 are provided with anti-slip protrusions to prevent the hand from slipping when holding them.
