Description

Technical Field

[0001] This utility model belongs to the field of head fixation technology, specifically referring to a foldable combination head fixation device suitable for medical magnetic resonance imaging examinations. Background Technology

[0002] Medical magnetic resonance imaging (MRI) is an advanced medical imaging technology that uses magnetic fields and radio frequency waves to acquire high-resolution images of internal human tissues, providing crucial information for clinical diagnosis and treatment. During MRI examinations, patient movement is one of the main factors contributing to image artifacts, which can interfere with the accuracy of diagnosis. Therefore, using head immobilization devices to significantly reduce patient head movement is an important means of improving MRI image clarity.

[0003] Traditional cranial fixation devices typically use pairs of soft blocks placed on either side of the patient's cheeks for immobilization. However, due to variations in cranial width among patients, medical institutions often need to prepare multiple sets of soft blocks of different thicknesses to accommodate these individual differences. This approach introduces numerous inconveniences in practice, such as the time spent searching for suitable soft blocks, the time cost of matching them with patients, and the increased distance traveled due to frequent retrieval of different soft blocks. These problems not only reduce examination efficiency but also increase management complexity and easily lead to the loss of soft blocks. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a foldable, modular head fixation device suitable for medical magnetic resonance imaging (MRI) examinations.

[0005] The technical solution adopted by this utility model is as follows: This utility model provides a foldable combination head fixation device suitable for medical magnetic resonance examination, including a soft block one, one side bottom corner of the soft block one is connected to one side bottom corner of the soft block two, the other side top corner of the soft block two is connected to one side top corner of the soft block three, and the other side bottom corner of the soft block three is connected to one side bottom corner of the soft block four.

[0006] Furthermore, soft block one, soft block two, soft block three and soft block four are all made of XPE material.

[0007] Furthermore, the soft block one has a length of 8cm, a width of 8cm, and a thickness of 2cm.

[0008] Furthermore, the second soft block has a length of 8cm, a width of 8cm, and a thickness of 1cm.

[0009] Furthermore, the length of the soft block three is 8cm, the width of the soft block three is 8cm, and the thickness of the soft block three is 2cm.

[0010] Furthermore, the soft block four has a length of 8cm, a width of 8cm, and a thickness of 1cm.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] (1) The soft blocks I, II, III and IV can be folded to form different layered structures with thicknesses between 1 and 6 cm to accommodate different cranial widths of examinees. This not only saves time in finding and replacing different soft blocks, but also reduces the distance the technician has to move during the operation, thereby improving the positioning experience and work efficiency, and thus improving the overall service quality.

[0013] (2) Soft blocks one, two, three and four are all made of XPE material, which has a light weight, excellent elasticity and softness, while providing excellent heat insulation and sound insulation, good waterproof performance, corrosion resistance and environmental protection and non-toxicity.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figures 1-6 As shown, this utility model proposes a foldable combination head fixation device suitable for medical magnetic resonance imaging examinations, including soft block 1, which has a length of 8cm, a width of 8cm, and a thickness of 2cm. One bottom corner of soft block 1 is connected to one bottom corner of soft block 2, which has a length of 8cm, a width of 8cm, and a thickness of 1cm. The other top corner of soft block 2 is connected to one top corner of soft block 3, which has a length of 8cm, a width of 8cm, and a thickness of 2cm. The other bottom corner of soft block 3 is connected to one bottom corner of soft block 4, which has a length of 8cm, a width of 8cm, and a thickness of 1cm. Soft blocks 1, 2, 3, and 4 are all made of XPE material.

[0025] In practical use, since soft blocks 1, 2, 3, and 4 are all made of XPE material, they are lightweight, have excellent elasticity and flexibility. Using the bottom and top corners of soft block 1 and 2 as folding points, fold soft blocks 1 and 2 in half. Using the top corners of soft block 2 and 3 as folding points, fold soft blocks 2 and 4 in half. Do not fold soft blocks 3 and 4. The bottom surfaces of soft blocks 3 and 4... Parallel, the thickness of soft block 1, soft block 2, and soft block 3 folded together is 5cm, and the thickness of soft block 4 is 1cm. Using the top corners of soft block 2 and soft block 3 as folding points, fold soft block 2 and soft block 3 in half. Using the bottom corners of soft block 3 and soft block 4 as folding points, fold soft block 3 and soft block 4 in half. Soft block 1 and soft block 2 are not folded. The bottom surface of soft block 1 is parallel to the bottom surface of soft block 2. Soft block 2, soft block 3, and soft block 4 are folded together. The thickness of the fourth fold is 4cm, and the thickness of soft block 1 is 2cm. Using the top corners of soft block 2 and soft block 3 as folding points, fold soft block 2 and soft block 3 in half. Soft block 1 and soft block 2 are not folded; the bottom surface of soft block 1 is parallel to the bottom surface of soft block 2. Soft block 3 and soft block 4 are not folded; the bottom surface of soft block 3 is parallel to the bottom surface of soft block 4. The thickness of the folded soft block 3 and soft block 3 is 3cm. Using the top corners of soft block 2 and soft block 3 as folding points, fold soft block 2 and soft block 3 in half. Using the top corner of 3 as the folding point, fold soft block 2 and soft block 3 in half. Using the bottom and top corners of soft block 3 and soft block 4 as folding points, fold soft block 3 and soft block 4 in half. Using the bottom and top corners of soft block 1 and soft block 2 as folding points, fold soft block 1 and soft block 2 in half. The thickness of the folded soft blocks 1, 2, 3, and 4 is 6cm. This is the overall workflow of this utility model. Repeat this step next time you use it.

[0026] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows:

[0027] The placement of soft blocks one, two, three, and four allows for folding into layered structures with varying thicknesses ranging from 1 to 6 centimeters to accommodate different patient cranial widths. This not only saves time in locating and replacing different soft blocks but also reduces the distance technicians need to move during the procedure, thereby improving the positioning experience and work efficiency, and ultimately enhancing the overall service quality. All four soft blocks are made of XPE material, which is lightweight, has excellent elasticity and flexibility, provides superior heat and sound insulation, is waterproof, corrosion-resistant, and environmentally friendly and non-toxic. During MRI examinations, the XPE material does not cause image interference.
