Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and in particular relates to a CT auxiliary device. Background Art

[0002] CT is a CT scan. It is a relatively advanced medical imaging technology in clinical practice. Its principle is to use X-ray beams, gamma rays, ultrasound and highly sensitive detectors to scan a certain part of the human body one section after another. After the scan, the computer will convert the scan information into image information output, and the radiologist will issue a diagnosis report. CT examination can be applied to any part of the body, including the head, neck, chest, abdomen, spine, limbs and other organs. The diagnosis and differential diagnosis of lesions, therefore, CT examination is of great significance.

[0003] When performing a CT scan on a patient's upper limbs, the patient is required to raise his upper limbs, but due to upper limb pain or other factors, it is difficult for the patient to reach the standard position required for scanning after raising his upper limbs. For example, after the patient raises his upper limbs, the upper limbs are too close to the head, and the scanned image is easily affected by the head scan, making it difficult for the doctor to see the specific situation of the lesion; or the upper limbs are constantly moving and shaking, or the patient cannot persist for enough time, causing the image to produce artifacts or unclear images. Therefore, in order to obtain clear upper limb CT scan images, it is necessary to use an upper limb fixing device to fix the patient's upper limbs, but the existing upper limb fixing device, such as a comfortable CT examination upper limb fixing device with patent number CN217659910U, includes a head fixing area, an arm support part, an elbow fixing part, and a wrist fixing part. The patient's upper limbs are contacted and fixed by the elbow fixing part and the wrist fixing part. The contact part of the patient's upper limb is relatively narrow, so the fixation effect is not good. In addition, the device cannot be adaptively adjusted for patients with different shoulder widths to make the distance between the upper limbs more consistent with the patient's own body structure, resulting in a lack of comfort for patients when using it. Utility Model Content

[0004] The utility model discloses a CT auxiliary device, which is intended to solve the technical problems in the prior art that the upper limb fixation device used in upper limb CT examination has a poor fixation effect on the upper limbs of patients and lacks comfort for the patients.

[0005] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present utility model are as follows:

[0006] A CT auxiliary device comprises a base, on which an upper limb fixing device is slidably arranged, the upper limb fixing device comprises a first fixing device and a second fixing device having the same structure and symmetrically arranged on the base, the first fixing device comprises a first limiting plate connected to the base, the first limiting plate is connected to the second limiting plate, the first limiting plate and the second limiting plate are located in the same plane, and both the first limiting plate and the second limiting plate are provided with limiting grooves for accommodating limbs, the inner side wall of the limiting groove is provided with an arm fixing mechanism, and the base is also provided with a head placement portion, and the head placement portion is arranged between the first fixing device and the second fixing device.

[0007] After adopting this technical solution, the head placement part can accommodate the patient's head so that the arm and the head do not touch each other, thereby increasing the imaging effect of the image. The limiting grooves in the first limiting plate and the second limiting plate can limit the entire arm of the patient, and then the arms of different patients can be adaptively fixed through the arm fixing device, so that the arm fixing device and the patient's arm are closely fitted, so that the patient's arm is firmly fixed by the limiting groove, increasing the fixing effect with the arm, reducing the artifacts caused by arm shaking or shaking, thereby further increasing the clarity of the image. And by fixing the patient's arm through the limiting groove, the fixing area between the limiting groove and the arm can be increased, and while increasing the fixing effect of the arm, cooperating with the arm fixing device can increase the comfort of the patient.

[0008] The first limiting plate is hinged to the second limiting plate, a connecting belt is arranged at one end of the second limiting plate away from the first limiting plate, and adhesive portions are arranged at two ends of the connecting belt close to the base.

[0009] After adopting this technical solution, the first limiting plate and the second limiting plate can rotate on the plane of the base, so that when the device fixes the patient's arm, it can adaptively adjust the bending arc between the forearm and the back arm according to the comfortable angle when the arm is raised, thereby increasing the comfort of the patient. The setting of the connecting belt adhesive part can enable the first limiting plate and the second limiting plate to be fixed on the base when fixing the patient's arm, thereby increasing the fixing effect of the patient's arm and the device.

[0010] Wherein, the adhesion part is a fleece-surface Velcro, and the base is provided with a hook-surface Velcro part cooperating with the fleece-surface Velcro, and the hook-surface Velcro part is arranged on a side of the base away from the first limiting plate.

[0011] After adopting this technical solution, the upper limb fixing device can be fixed on the base through the connection between the fleece-surface Velcro and the hook-surface Velcro.

[0012] Wherein, the connecting belt is an elastic belt.

[0013] After adopting this technical solution, the elasticity of the connecting belt can adapt to the patient's arm or wrist size when the connecting belt is connected to the adhesion part, thereby increasing the patient's comfort and the arm fixation effect.

[0014] Among them, the base is an inclined structure, the base includes a fixed plate, the fixed plate is hinged with a rotating plate, the first limiting plate and the second limiting plate are slidably arranged on the rotating plate, the head placement part includes a U-shaped through groove arranged on the rotating plate, and the fixed plate is provided with a headrest that cooperates with the U-shaped through groove.

[0015] After adopting this technical solution, the base is an inclined structure that can be adaptively adjusted to the human body arc formed between the cervical spine and the torso when the patient lies down. It conforms to ergonomic design and can increase the comfort of the user. The angle between the rotating plate and the fixed plate can be changed by rotating the rotating plate and the fixed plate, so that the angle of the arm raising can be changed, which is convenient for the CT scanning device to scan. At the same time, the arm raising can also increase the comfort of some patients such as patients with frozen shoulder when performing upper limb scanning. The rotating plate is slidably connected to the upper limb fixing device, and the position of the upper limb fixing device on the device can be adaptively changed according to the patient's shoulder width, thereby increasing the comfort of the patient. The U-shaped through groove can accommodate the patient's head, reduce the contact between the patient's head and the arm, thereby reducing the possibility of ghosting and increasing the clarity of the image. The headrest can increase the comfort during the scan and make it easier for the patient to persist.

[0016] Among them, sliding grooves with the same structure are symmetrically arranged on both sides of the U-shaped through groove, and the sliding grooves are slidably connected with sliding parts. The first limiting plate is connected to the sliding part, and a pin key is arranged on the first limiting plate.

[0017] After adopting this technical solution, the relative position between the first limit plate and the U-shaped through groove can be changed by sliding the sliding member in the slide groove, so that the position between the through grooves can adapt to the patient's shoulder width, increasing the practicality of the device, and the pin key can fix the first limit plate that has been determined in position, and fix the position of the first limit plate on the base.

[0018] The rotating plate is hinged with a supporting plate, and the fixed plate is provided with a plurality of convex strips, and a slot is formed between each adjacent convex strip, and the supporting plate is clamped in the slot.

[0019] After adopting this technical solution, the position of the slot of the support plate can be changed through the slot formed between the convex strips, thereby changing the angle between the rotating plate and the fixed plate, changing the angle between the upper limb adjustment device and the CT scanning device bed board, and increasing the patient's comfort.

[0020] Among them, the arm fixing mechanism includes an inflatable and deflation airbag arranged in a limiting groove, the inflatable and deflation airbag is connected to an inflatable and deflation mechanism, the inflatable and deflation mechanism includes an air pipe, one end of the air pipe is provided with an interface, and the interface is detachably connected to an inflation device.

[0021] After adopting this technical solution, the limit slot cooperates with the inflatable and deflation airbag, and the inflatable and deflation airbag can be connected to an electric inflatable and deflation pump or a manual pressure pump through the interface to inflate or deflate the inflatable and deflation airbag. The inflatable and deflation airbag can be adaptively expanded or reduced according to the patient's arm size, so that the inflatable and deflation airbag fits the curve of the patient's arm and increases the fixation effect. It reduces the artifacts caused by arm shaking or trembling, thereby further increasing the clarity of the image.

[0022] Wherein, a shoulder pillow is detachably connected to one side of the base close to the first limiting plate.

[0023] After adopting this technical solution, the shoulder pillow can increase the comfort of patients with shoulder discomfort when using the device, allowing patients to better persist in the scanning process.

[0024] Wherein, the limiting through groove is an open ring groove, the cross section of the open ring groove is an arc shape, and the opening is smaller than the diameter of the open ring groove.

At the same time, the opening of the open ring groove is smaller than the diameter of the open ring groove, so the patient's arm that has been in contact with the inflated and deflated airbag can be fixed.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0027] (1) The first limiting plate, the second limiting plate and the inflatable and deflated airbag are used to increase the contact area between the patient's upper limb and the upper limb fixation device. At the same time, the inflatable and deflated airbag can adaptively limit the patient's upper limb, thereby increasing the fixation effect, reducing the shaking of the patient's arm, and improving the imaging effect.

[0028] (2) By using a slide groove and a slider, the distance between the upper limb fixation device and the U-shaped groove can be changed according to the patient's shoulder width, thereby increasing the practicality of the device during use.
