Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical devices, and in particular to a headrest for CT contrast-enhanced examination. Background Technology
[0002] Currently, CT scans with contrast are required for accurate diagnosis. In this case, the patient's upper limb needs to be raised, a vein is punctured in the elbow crease, contrast agent is injected, and the patient is asked to keep the upper limb still for about 10 minutes or longer.
[0003] However, many patients cannot remain still due to their illness, which causes ghosting in the scan. Furthermore, accidents can easily occur during the examination if the limbs move. In addition, the indwelling needle is usually inserted into the median cubital vein in the right elbow. Medical staff connect the contrast agent infusion tubing to the indwelling needle in the patient's body to administer the contrast agent. However, the contrast agent infusion tubing is not fixed in one place and is prone to slippage. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a headrest for CT contrast examination.
[0005] This utility model provides the following technical solution: a headrest for CT contrast examination, comprising a headrest body, two second grooves and two third grooves extending from front to back through the upper part of the headrest body, and a first groove formed in the middle of the upper part of the headrest body. The two second grooves are respectively distributed on both sides of the upper part of the headrest body, and the two third grooves are also respectively distributed on both sides of the upper part of the headrest body. The first groove is used to accommodate the patient's head, the second grooves are used to accommodate the patient's hands, and the third grooves are used to accommodate infusion tubes. The headrest also includes a fixing component for restricting the movement of the patient's hands. At least two fixing components are provided and are respectively located at the two third grooves. The fixing component includes a Velcro female and a Velcro male connected to the headrest body. The Velcro female and the Velcro male are respectively located on both sides of the second groove. When the patient's hands are placed in the second groove, the patient's hands are fixed by connecting the Velcro female and the Velcro male.
[0006] Furthermore, both the first groove and the second groove are arc-shaped.
[0007] Furthermore, the third groove is arc-shaped or square.
[0008] Furthermore, the headrest also includes a blocking member disposed in the third groove, the blocking member being used to block the infusion tube that is stuck in the third groove; the blocking member includes a connecting plate connected to the pillow body, and a plurality of elastic blocking blocks disposed on the connecting plate.
[0009] Furthermore, the blocking block includes an elastic portion fixedly connected to the connecting plate, and an arc-shaped portion provided on the elastic portion.
[0010] Furthermore, the headrest also includes an anti-slip component, which includes two friction strips respectively disposed on the side wall of the third groove. The side of the friction strip near the opening of the third groove is arc-shaped, and the infusion tube is located between the two friction strips.
[0011] Furthermore, the anti-slip component also includes an expansion unit, which includes two expansion bladders respectively disposed on the two friction strips, an air tank with an inner cavity disposed on the pillow body, a guide pipe communicating with the inner cavity of the air tank, and a diversion pipe communicating with the two expansion bladders and the guide pipe. The expansion unit also includes a compression plate slidably connected in the inner cavity of the air tank, and a driving member for driving the compression plate to move.
[0012] Furthermore, the driving component includes a screw rotatably connected to the gas storage tank, a knob fixedly connected to the screw, and the screw being threadedly connected to the extrusion plate.
[0013] The beneficial effects of this utility model are as follows: the second groove limits the patient's hand on both sides, and then medical staff fix the patient's hand by attaching the female Velcro to the male Velcro. The cooperation between the second groove and the female and male Velcro allows the patient's hand to be placed in the second groove for a long time, which is convenient for medical staff to perform CT contrast examinations on the patient. When it is necessary to inject contrast agent into the patient's body, medical staff can connect the contrast agent infusion tube to the indwelling needle on the patient's body and place the infusion tube into the third groove. The third groove can organize and restrict the infusion tube, preventing the infusion tube from hanging outside due to lack of organization, causing contact between external objects and the infusion tube, which can easily cause the infusion tube to slip off and affect the treatment and examination.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] A headrest for CT contrast-enhanced examinations, such as Figure 1 and Figure 2As shown, the headrest includes a pillow body 1, two second grooves 3 and two third grooves 4 extending from front to back through the upper part of the pillow body 1, and a first groove 2 formed in the middle of the upper part of the pillow body 1. The two second grooves 3 are respectively distributed on both sides of the upper part of the pillow body 1, and the two third grooves 4 are also respectively distributed on both sides of the upper part of the pillow body 1. The first groove 2 is used to accommodate the patient's head, the second grooves 3 are used to accommodate the patient's hands, and the third grooves 4 are used to accommodate infusion tubes. The headrest also includes a fixing component 5 for restricting the movement of the patient's hands. At least two fixing components 5 are provided and are respectively located at the two third grooves 4. The fixing component 5 includes a Velcro female 51 and a Velcro male 52 connected to the pillow body 1. The Velcro female 51 and the Velcro male 52 are respectively located on both sides of the second groove 3. When the patient's hands are placed in the second groove 3, the patient's hands are fixed by connecting the Velcro female 51 and the Velcro male 52.
[0025] The first groove 2 and the second groove 3 are arc-shaped, and the third groove 4 is either arc-shaped or square. When using this headrest, the patient's head can be placed in the first groove 2. When a CT scan is needed, the patient can raise their hand towards their head and place it in the second groove 3. The second groove 3 can limit the movement of the patient's hand on both sides. Then, medical staff can fix the patient's hand by attaching the female Velcro 51 to the male Velcro 52. The cooperation between the second groove 3 and the female Velcro 51 and male Velcro 52 allows the patient's hand to be placed in a stable position for an extended period. The contrast agent is inserted into the second groove 3 to facilitate CT enhancement examination of the patient by medical staff. When contrast agent needs to be injected into the patient's body, medical staff can connect the contrast agent infusion tube to the indwelling needle on the patient's body and place the infusion tube into the third groove 4. The third groove 4 can organize and restrict the infusion tube to prevent it from hanging outside due to lack of organization, causing contact between external objects and the infusion tube, which may easily cause the infusion tube to slip and affect the treatment and examination. Conversely, after the patient's examination is completed, it is only necessary to separate the female Velcro 51 and the male Velcro 52.
[0026] like Figure 3 As shown, the headrest also includes a blocking member 6 disposed in the third groove 4, the blocking member 6 being used to block the infusion tube that is stuck in the third groove 4; the blocking member 6 includes a connecting plate 61 connected to the pillow body 1, and a plurality of elastic blocking blocks 62 disposed on the connecting plate 61; the blocking block 62 includes an elastic part 621 fixedly connected to the connecting plate 61, and an arc-shaped part 622 disposed on the elastic part 621.
[0027] It is understandable that when the infusion tube needs to be inserted into the third groove 4, the medical staff first pushes the infusion tube into the third groove 4 through the gap between the arc-shaped part 622 and one side wall of the third groove 4. When the infusion tube is pushed in, it squeezes the arc-shaped part 622, and the elastic part 621 deforms. When the infusion tube is fully inserted into the third groove 4, the elastic part 621 returns to its original position, and the elastic part 621 will drive the arc-shaped part 622 to return to its original position, thereby blocking the upper part of the infusion tube. Thus, through the blocking block 62 and the third groove 4, the four sides of the infusion tube are restricted, preventing the infusion tube from sliding out of the second groove 3. When it is necessary to remove the infusion tube, the medical staff only needs to pull the infusion tube to pull it out through the gap between the arc-shaped part 622 and one side wall of the third groove 4.
[0028] like Figure 4 As shown, the headrest also includes an anti-slip component 7, which includes two friction strips 71 respectively disposed on the side wall of the third groove 4. The side of the friction strip 71 near the opening of the third groove 4 is arc-shaped 72, and the infusion tube is located between the two friction strips 71.
[0029] It is understandable that after medical staff insert the infusion tube into the third groove 4, the infusion tube can be placed between the two friction strips 71, and the two friction strips 71 can be made to fit against the outer wall of the infusion tube, so that friction is generated between the friction strips 71 and the outer wall of the infusion tube, thereby restricting the infusion tube from moving back and forth in the third groove 4.
[0030] like Figure 5 and Figure 6 As shown, the anti-slip component 7 further includes an expansion unit 73, which includes two expansion bladders 731 respectively disposed on the two friction strips 71, an air tank 734 with an inner cavity disposed on the pillow body 1, a guide pipe 733 communicating with the inner cavity of the air tank 734, and a diversion pipe 732 communicating with the two expansion bladders 731 and the guide pipe 733. The expansion unit 73 also includes a compression plate 737 slidably connected in the inner cavity of the air tank 734, and a driving member for driving the compression plate 737 to move. The driving member includes a screw 736 rotatably connected to the air tank 734, a knob 735 fixedly connected to the screw 736, and the screw 736 being threadedly connected to the compression plate 737.
[0031] Furthermore, when the infusion tube is inserted between the two friction strips 71, it is also positioned between the two expansion bladders 731. The operator can rotate the knob 735, which in turn rotates the screw 736. The rotation of the screw 736 moves the compression plate 737, which pushes the air in the air tank 734 into the expansion bladder 731 through the guide tube 733 and the diverter tube 732. This causes the expansion bladder 731 to inflate and enclose the outer wall of the infusion tube, thereby further preventing the infusion tube from moving within the third groove 4. Conversely, the infusion tube needs to be moved out of the third groove 4. When removing the IV tubing, medical staff simply need to rotate knob 735 in the opposite direction. Knob 735 will drive screw 736 to rotate, and screw 736 will push compression plate 737 to move in the opposite direction to knob 735, thereby drawing the gas in the expansion bladder 731 into the gas storage tank 734. The expansion bladder 731 will no longer expand, and medical staff can then remove the IV tubing from the second groove 3. In other embodiments, the driving component can be a sliding rod, which is fixedly connected to compression plate 737, similar to the structure of a syringe. By pushing the sliding rod to move, the expansion bladder 731 can be inflated and deflated.
[0032] In summary, the second groove 3 restricts the patient's hand on both sides. Then, medical staff attach the Velcro 51 to the Velcro 52 to fix the patient's hand. The cooperation between the second groove 3 and the Velcro 51 and Velcro 52 allows the patient's hand to be placed in the second groove 3 for an extended period, facilitating CT contrast examinations. When contrast agent needs to be injected into the patient, medical staff can connect the contrast agent infusion tube to the indwelling needle on the patient and place the infusion tube into the third groove 4. The third groove 4 can organize and restrict the infusion tube, preventing it from hanging outside and causing contact with external objects, which could lead to slippage and affect treatment and examination.
