Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head support for CT examination in the imaging department. Background Art

[0002] CT examination is a relatively advanced modern medical scanning technology, mainly used to scan the human brain. When performing a head CT examination, in order to ensure image quality and prevent the patient's head from moving during the scan, a head rest is usually required to fix the head. The head rest is a device specially designed to fix the head, usually made of plastic or metal, with a certain rigidity and comfort.

[0003] Although the existing CT examination head support can fix the head well, when performing CT scanning, due to the high intensity of the X-ray beam, a certain amount of noise will be generated during the scanning process. This noise mainly comes from the vibration generated by the interaction between the X-ray beam and the air, bones and other substances with different densities when passing through human tissue. This noise may cause discomfort to patients to a certain extent, especially for those who are sensitive to noise. Therefore, an imaging CT examination head support is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 In this embodiment, a headrest for CT examination in the imaging department includes a base 1, a head support pad 2 is fixedly installed on the top of the base 1, a noise-proof limiting mechanism 3 is arranged between the inside and the top of the base 1, and an adjustment limiting mechanism 4 is arranged on the noise-proof limiting mechanism 3.

[0024] The noise-proof limiting mechanism 3 includes a bidirectional threaded rod 301, a limiting rod 302, a movable sleeve 303, a fixed plate 304, an adjustment plate 305 and a soundproof earmuff 306. The bidirectional threaded rod 301 is rotatably installed inside the base 1, and a limiting rod 302 located on the lower side of the bidirectional threaded rod 301 is fixedly installed between the left and right inner walls of the base 1. A movable sleeve 303 is movably installed between the limiting rod 302 and both ends of the outer surface of the bidirectional threaded rod 301, and a fixing plate 304 is fixedly installed on the top of the two movable sleeves 303. Adjustment plates 305 are movably installed on the outer surfaces of the two fixing plates 304, and soundproof earmuffs 306 are fixedly installed on the opposite sides of the two adjustment plates 305.

[0025] A bearing seat is fixedly installed on the left inner wall of the base 1, and the left end of the two-way threaded rod 301 is rotatably installed with the left inner wall of the base 1 through the bearing seat, and a hand crank is fixedly installed on the right end of the two-way threaded rod 301. Openings compatible with two movable sleeves 303 are opened at both ends of the top of the base 1. The tops of the two movable sleeves 303 pass through the openings and extend to the bottom of the fixed plate 304. The two-way threaded rod 301 is driven to rotate inside the base 1 by rotating the hand crank outside the base 1, so that the two movable sleeves 303 drive the fixed plate 304 and the adjustment plate 305 to move relative to each other through the opening, thereby adjusting the distance between the two soundproof earmuffs 306, so that the two soundproof earmuffs 306 wrap the patient's ears to reduce noise. It is suitable for patients with different head sizes. The soundproof earmuffs 306 can use X5A earmuffs and other earmuffs with sound insulation effect. After wrapping the patient's ears, the noise generated by the X-ray camera is isolated, the patient's comfort is improved, and the patient's head is prevented from moving, and the patient's head is fixed.

[0026] The adjustment and limiting mechanism 4 includes a positioning rod 401, a side baffle 402, a limiting piece 403, a spring 404 and a positioning hole 405. The positioning rod 401 is movably installed on the opposite side of the two adjustment plates 305, and a side baffle 402 is fixedly installed between one end of each two positioning rods 401. Two limiting pieces 403 are fixedly installed on the opposite side of the two adjustment plates 305. The outer surfaces of the four positioning rods 401 are sleeved with springs 404, and two groups of positioning holes 405 are provided on the opposite side of the two fixed plates 304.

[0027] The number of the two groups of positioning sockets 405 is eight each, and the eight positioning sockets 405 are distributed equidistantly at both ends of one side of the fixing plate 304 in a row of four. The eight positioning sockets 405 are all compatible with the positioning rod 401. By setting a plurality of positioning sockets 405, the height of the adjustment plate 305 can be adjusted in multiple gears, which makes it easy to adjust the height of the soundproof earmuffs 306. It is flexible to use and meets the needs of patients with different head sizes.

[0028] When implementing, follow these steps:

[0029] 1) First, the patient's head is placed on the head support pad 2, and then the height of the two soundproof earmuffs 306 is adjusted. When adjusting the height, the handle is first pulled outward, and the handle drives the side baffle 402 to move away from the adjustment plate 305, and the side baffle 402 drives the two positioning rods 401 to move in the same direction;

[0030] 2) Then, during the movement of the two positioning rods 401, the spring 404 is stretched between the side baffle 402 and the limiting plate 403, and the expansion of the spring 404 causes the two positioning rods 401 to withdraw from the interior of the positioning hole 405;

[0031] 3) Move the two adjustment plates 305 upward or downward to a suitable height, release the handle, and the spring 404 returns to its original state and drives the positioning rod 401 to be inserted into the corresponding positioning hole 405 to fix the position of the adjustment plate 305;

[0032] 4) Finally, the hand crank is turned to drive the bidirectional threaded rod 301 to rotate. Under the limit of the limit rod 302, the rotation of the bidirectional threaded rod 301 drives the two movable sleeves 303 to move relative to each other between the outer surfaces of the bidirectional threaded rod 301 and the limit rod 302. The two movable sleeves 303 drive the two fixed plates 304 to move relative to each other. The two fixed plates 304 drive the two adjustment plates 305 to move relative to each other, thereby driving the two sound insulation earmuffs 306 to move relative to each other to wrap the patient's ears.

[0033] In summary, the imaging department CT examination head support can not only isolate noise but also prevent the patient's head from moving during the examination by setting the noise-proof limiting mechanism 3. When the patient's head is placed on the head supporting pad 2, the distance between the two sound-proof earmuffs 306 is adjusted so that the two sound-proof earmuffs 306 move relatively to wrap the patient's ears, effectively isolate the noise generated during the CT scan, and reduce the patient's discomfort. In addition, the distance between the two sound-proof earmuffs 306 can be flexibly adjusted. When the two sound-proof earmuffs 306 wrap the ears, the purpose of limiting the head is achieved to prevent the patient's head from moving. It can isolate noise and fix the head.

[0034] Furthermore, by setting an adjustment limit mechanism 4, the height of the soundproof earmuffs 306 can be adjusted, so that the height and distance of the soundproof earmuffs 306 can be flexibly adjusted, so that the soundproof earmuffs 306 can be adjusted to a suitable width and height according to the size of the patient's head shape, suitable for different patients, and meeting different usage requirements.
