Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to an upper limb support device for CT examination. Background Technology

[0002] CT scans are a common imaging technique in modern clinical medicine. They use X-ray beams to perform tomographic scanning of the human body and, with the help of computer processing, generate detailed images of the body's internal structures. They offer rapid and clear imaging capabilities and are widely used in the diagnosis of various diseases. A CT scanner mainly consists of three core parts: the scanning unit, the computer system, and the image display and system storage. The scanning unit includes a gantry, which houses the X-ray tube and detectors, and a support frame to elevate the patient's torso. Patients typically lie supine on the support frame during the scan.

[0003] However, in actual operation, especially when scanning the area above the chest and below the head, in order to ensure the scanning effect, the patient usually needs to raise both hands above the head to fully expand the chest area. However, a CT scan often takes a long time to complete. For the aforementioned patients, firstly, the comfort is poor, and secondly, the patient does not have enough physical strength to maintain a relatively still state for a long time, resulting in deviations in the scanning effect. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an upper limb support device for CT examinations. The technical problem this invention aims to solve is: how to improve the scanning imaging effect while ensuring comfort.

[0005] The purpose of this utility model can be achieved through the following technical solution: an upper limb support device for CT examination, comprising a base plate, characterized in that two oppositely arranged connecting brackets are connected to the base plate, and each of the two connecting brackets can be detachably connected to a long strip-shaped hand rest on the opposite side, and each hand rest is arranged in a transverse direction.

[0006] The working principle of this upper limb support device for CT scans is as follows: Before the examination, the patient lies supine on the support frame and adjusts their posture so that their head is behind the upper limb support device. Before the medical staff starts the device, the patient raises both arms overhead according to the medical staff's instructions, so that the arms and the two armrests are supported by the armrests, thus avoiding the patient's arms being suspended in the air without support for a long time during the examination, ensuring greater comfort. Secondly, it can also prevent the patient's arms from shaking during the examination, ensuring the quality of the scan imaging.

[0007] In the aforementioned upper limb support device for CT examination, the base plate is rectangular, and each connecting bracket is cuboid and vertically arranged. Each connecting bracket has a connection port near its bottom, extending through both sides of the bracket. Each connecting bracket is slidably connected to the base plate via these ports. This design allows the two connecting brackets to slide along the length of the base plate, i.e., along the width of the support frame's bed board. This allows for adjustment of the spacing between the two connecting brackets on the base plate, ensuring that the positions of the two armrests meet the actual needs of patients with different body shapes.

[0008] In the aforementioned upper limb support device for CT examination, two racks are provided along the length direction at the middle of the side surface of the base plate. The two racks are spaced apart and opposite to each other along the width direction of the base plate. A damping gear set is provided on the inner wall of the top of the connection port, and the damping gear set meshes with the two racks. By utilizing the cooperation of the double racks and the damping gear set, the sliding direction of the two connecting brackets on the base plate is guided, avoiding the connecting brackets from shifting or getting stuck during sliding. Secondly, the damping effect of the damping gear set ensures that the connecting brackets remain in position after adjustment, improving their positioning stability. It is worth mentioning that the damping gear set used in this application can adopt existing technology.

[0009] In the aforementioned upper limb support device for CT examination, a receiving groove is formed along the length direction at the middle of the side surface of the base plate. Two racks are respectively fixed to the two side walls of the receiving groove. The damping gear set includes a first damping gear and a second damping gear embedded in and meshing with each other in the receiving groove. The first damping gear meshes with one of the racks, and the second damping gear meshes with the other rack. This arrangement ensures smooth operation of the damping gear set and the two racks, preventing excessive resistance from causing sluggish sliding of the connecting bracket.

[0010] In the aforementioned upper limb support device for CT examination, a snap-fit ​​groove is provided on the outer wall of the connecting bracket, and the hand rest is snapped into the snap-fit ​​groove. This ensures convenient assembly and disassembly of the hand rest and the connecting bracket.

[0011] In the above-mentioned upper limb support device for CT examination, the outer wall of the armrest has an outwardly protruding limiting post, and the outer wall of the connecting bracket has a plurality of limiting grooves communicating with the locking groove along the depth direction of the locking groove. The plurality of limiting grooves have different depths and are spaced around the locking groove. The limiting post is embedded and positioned in any one of the limiting grooves. If there is a slight deviation between the patient's arm position and the position of the armrest after the connecting bracket has been adjusted, and readjusting the positions of the two connecting brackets is time-consuming and laborious, medical staff can pull the armrest out of the locking slot and rotate it a certain distance. This will cause the limiting post on the armrest to rotate a certain distance as well. After that, when the medical staff reinserts the armrest into the locking slot, the limiting post on its outer wall can be inserted into another limiting groove opened on the outer wall of the connecting bracket. Since the opening depth of each limiting groove is different, it has a limiting effect on the insertion depth of the armrest and the locking groove. This allows for a slight adjustment of the length of the armrest protruding from the outer wall of the connecting bracket, ensuring convenient adjustment while making the position of the armrest meet the actual needs of the patient.

[0012] In the aforementioned upper limb support device for CT examination, sliders are fixedly connected to both ends of the lower side of the base plate, and the sliders protrude from the bottom wall of the connecting bracket. The sliders allow for sliding connection between the base plate and the slide rails on both sides of the support frame bed, enabling adjustment of the distance between the base plate and the patient's head. Furthermore, the protrusion of the sliders from the bottom of the connecting bracket prevents friction between the connecting bracket and the support frame bed, thus preventing the connecting bracket from becoming stuck.

[0013] Compared with existing technologies, this upper limb support device for CT scans has the following advantages:

[0014] By sliding two always-opposing connecting brackets on the base plate, and using the connecting brackets to support the hand rests, the connecting brackets are positioned on the base plate by using a damping gear set and rack to guide the sliding direction of the connecting brackets. This ensures that the hand rests on each connecting bracket remain in place, ensuring that the patient's arm has something to lean on during the examination, guaranteeing their comfort while improving the scanning imaging effect.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1-3 As shown, the upper limb support device for CT examination includes a base plate 1, two connecting brackets 11, and two hand rests 111. The base plate 1 is a rectangular plate, and the two connecting brackets 11 are cuboid in shape and vertically arranged. Each connecting bracket 11 has a connecting port 112 that runs through its two sides near the bottom. The two connecting brackets 11 are inserted into the base plate 1 from both ends through the connecting ports 112, so that the two connecting brackets 11 are always in opposite positions and can slide on the base plate 1 to adjust the distance between them.

[0024] Combination Figure 4 and Figure 5 A receiving groove 13 is provided along the length direction at the middle of the upper side of the base plate 1. A rack 12 is fixed on both sides of the receiving groove 13. A damping gear set 2 is installed on the inner wall of the top of the connection port 112 of each connecting bracket 11. The damping gear set 2 can adopt the existing technology. Specifically, it is composed of a first damping gear 21 and a second damping gear 22 that mesh with each other. The first damping gear 21 is embedded in the receiving groove 13 and meshes with one of the racks 12. The second damping gear 22 is embedded in the receiving groove 13 and meshes with the other rack 12.

[0025] Combination Figure 6Each connecting bracket 11 has a snap-fit ​​groove 113 on its outer side wall. One end of each of the two handrails 111 is inserted into the snap-fit ​​groove 113 of the two connecting brackets 11, thereby achieving the connection and positioning of the handrails 111 and the connecting brackets 11. In addition, an outwardly protruding limiting post 1111 is integrally formed on the outer side wall of each end of the handrail 111. Several limiting grooves 114 are formed on the outer side wall of the connecting bracket 11 along the depth direction of the snap-fit ​​groove 113, spaced apart around the snap-fit ​​groove 113. The limiting grooves 114 are all set through the inner wall of the locking grooves 113, and the depths of the several locking grooves are different. The advantage of this design is that after adjusting the position of the connecting bracket 11 for different patient body shapes, if there is still a small error that causes discomfort to the patient's arm when leaning on it, there is no need to adjust the position of the connecting bracket 11 again. The armrest 111 can be pulled out from the locking groove 113 (at this time, the limiting post 1111 also comes out from one of the limiting grooves 114), and then the medical staff can put the armrest 111 into place. After rotating a certain distance, one end is reinserted into the locking groove 113, and the limiting post 1111 is inserted into the corresponding limiting groove 114. Through the cooperation of the limiting post 1111 and the limiting groove 114, the protruding length of the armrest 111 is adjusted slightly to ensure it fits the patient's arm. Alternatively, a soft cover can be wrapped around the armrest 111. It is worth emphasizing that when using this upper limb support device for CT examination, the actual distance between the outer ends of the two armrests 111 may be greater than the width of the bed board, but will not exceed the inner diameter of the scanning channel on the scanning gantry. Therefore, there will be no obstruction or interference. In addition, at the lower side of the bottom plate 1, at both ends of the edge, there are also sliders 14 for sliding connection with the slide rail on the bed board, which are screwed and locked. This allows the bottom plate 1 to slide and adjust along the length of the bed board of the support frame, so that the upper limb support device for CT examination can adjust the distance between itself and the patient's head, eliminating the need for the patient to repeatedly get up and adjust their position, making it more convenient to use.
