Abstract
Description
Technical Field
[0001] This application relates to the field of contrast pads, specifically to a medical contrast positioning pad. Background Technology
[0002] During interventional procedures under DSA (Digital Subtraction Angiography), some children, due to their young age and low level of cooperation, are prone to unconscious movement or body swaying during the angiography process, leading to blurred images, increased artifacts, and seriously affecting diagnostic accuracy. Current clinical methods for pediatric angiography have many limitations: some fixation devices use materials containing metal components or high-density materials, which can create contrast interference in the images, interfering with the examination results; at the same time, existing headrests and other support structures are mostly fixed in shape, unable to be flexibly adjusted according to the specific head height requirements of different angiography examinations, making it difficult to meet the needs of precise positioning. Utility Model Content

[0020] As per the instruction manual Figure 1-4 As shown: A medical imaging positioning pad includes: a pad body 100, a headrest 200, and a torso fixation strap 110; the torso fixation strap 110 is disposed in the upper middle part of the pad body 100, one end of the torso fixation strap 110 is pressed against the top surface of the pad body 100 by a first mounting structure 111, and the other end is pressed against the top surface of the pad body 100 by a second mounting structure 112; a head support air cushion 220 is installed at the bottom of the headrest 200, and the bottom of the support air cushion 220 is glued and fixed to the upper top surface of the pad body 100.
[0021] The working principle of a medical imaging positioning pad: Medical staff can restrict the child's movement using the trunk fixation strap 110, securing the child's torso to the pad 100. The pad 100 is divided into multiple support compartments, providing support for the child's torso and limbs, preventing bedsores. Simultaneously, the outer layer of the pad 100 is made of breathable silicone membrane, and each support compartment is filled with one or more materials selected from pure cotton, breathable polyurethane sponge, and medical-grade polyester fiber, without any metal components or high-density substances, thus avoiding artifacts in the images. When the fixation strap is tightened, the resulting friction effectively restricts changes in the child's position caused by involuntary movement or body swaying during the imaging process, ensuring the child maintains a stable posture throughout prolonged imaging examinations. Furthermore, depending on the requirements of the child's brain examination, if fine adjustments to the child's head height or angle are needed, medical staff can flexibly adjust the head support height and angle by appropriately inflating and deflating the support air cushion 220 to meet the specific requirements of different imaging examinations for the child's head position. The headrest 200 has an outer layer made of breathable silicone membrane and is filled with one or more of the following materials: pure cotton, breathable polyurethane sponge, and medical-grade polyester fiber. It contains no metal components or high-density substances, will not form artifacts in images, and has good breathability and biocompatibility.
[0022] In this embodiment, a medical angiography positioning pad securely fixes the child's torso with a trunk fixation strap to avoid imaging deviations caused by body position movement, preventing artifacts during surgery and ensuring the clarity and accuracy of DSA angiography images. Simultaneously, by appropriately inflating and deflating the support air cushion, the height and angle of head support can be flexibly adjusted to meet the specific requirements of different angiography examinations for the child's head position. The headrest is made of metal-free or high-density materials, preventing artifact formation in images and possessing good breathability and biocompatibility. This effectively improves the convenience of clinical operation and the practical value of the equipment.
[0023] Specifically, a torso compression airbag 115 is glued and fixed to the inner layer of the torso fixation strap 110. The torso compression airbag 115 is connected to an air compressor (not shown in the figure) through a torso airbag connecting tube. The torso compression airbag 115 is made of non-contrast-producing and breathable medical material, which does not interfere with the image quality of DSA imaging. Medical staff can adjust the tightness of the torso fixation strap 110 by inflating and deflating the torso compression airbag 115 to firmly fix the child's torso on the pad 100, ensuring that the child's torso is stable and does not shake during the imaging process, and preventing image blurring caused by changes in body position.
[0024] Specifically, neck restraint blocks 210 are fixedly installed at both ends of the head support air cushion 220 at the bottom of the headrest 200. The top edge of the neck restraint blocks 210 is sewn to the bottom edge of both ends of the headrest 200. The outer layer of the neck restraint blocks 210 is made of silicone breathable membrane, and the inside is filled with one or more materials selected from pure cotton, polyurethane breathable sponge, and medical-grade polyester fiber. During the inflation and deflation of the head support air cushion 220, the two neck restraint blocks 210 always support and fix the child's neck, avoiding neck displacement caused by air cushion deformation or unconscious movement of the child, ensuring the stable coordinated position of the neck and head, and further reducing artifact interference in angiography.
[0025] Specifically, the head support air cushion 220 has a vent 225 on its side for connecting to the air compressor vent pipe (not shown in the figure) to inflate the support air cushion 220 and raise the upper part of the headrest 200; when the support air cushion 220 deflates, the upper part of the headrest 200 lowers.
[0026] Specifically, the lower top surface of the pad 100 is provided with a first leg fixing hook and loop fastener 120 and a second leg fixing hook and loop fastener 125. The bottom surfaces of the first leg fixing hook and loop fastener 120 and the second leg fixing hook and loop fastener 125 are fixed to the top surface of the pad 100 by any of the following methods: adhesive, screw fixing, or bolt fixing.
[0027] Specifically, the lower top surface of the pad 100 is provided with a first lower leg fixing hook and loop fastener 130 and a second lower leg fixing hook and loop fastener 135. The bottom surfaces of the first lower leg fixing hook and loop fastener 130 and the second lower leg fixing hook and loop fastener 135 are fixed to the top surface of the pad 100 by any of the following methods: adhesive, screw fixing, or bolt fixing.
[0028] Specifically, the hook and loop fasteners allow for flexible adjustment of the tightness of the fasteners according to the thickness of the child's legs. This not only prevents the child from shifting their position due to limb movement by providing a flexible restraint that fits the legs, but also ensures the coordinated stability of the torso, head, and legs. At the same time, the hook and loop fasteners are made of non-radioactive materials, so they will not interfere with the imaging and will effectively guarantee the quality of the examination.
[0029] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
