Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a positioning pillow for CT-guided lung puncture. Background Technology

[0002] CT-guided lung biopsy is a lung puncture technique performed with the precise assistance of CT scans. Its advantages lie in its accurate positioning: it clearly displays the anatomical structure of the lung lesion and surrounding tissues, accurately determining the puncture point, needle direction, and depth, thus improving the success rate and reducing damage to normal tissues. During the puncture, the position of the puncture needle can be observed in real time via CT scans, allowing for timely adjustments to ensure the needle accurately reaches the lesion site.

[0003] During the procedure, the patient assumes a suitable position on the CT examination table. A CT scan is performed on the lesion to determine the puncture level and point, which are then marked on the skin. The doctor holds the puncture needle and inserts it along the predetermined direction and angle. After reaching the predetermined depth, a CT scan is performed to confirm the needle's position. If the position is inaccurate, adjustments are made. Therefore, the patient needs to cooperate with the positioning to achieve the optimal needle insertion angle and position during the puncture. However, the patient lies on the CT table, which has no armrests or support points, making it difficult for the patient to maintain this position, leading to positional shifts that affect the doctor's operation. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a positioning pillow for CT-guided lung puncture.

[0005] The present invention provides the following technical solution: a positioning pillow for CT-guided lung puncture, comprising a headrest and a torso detachably connected to the headrest;

[0006] The headrest includes two side pieces and a soft material intermediate piece connecting the two side pieces. The highest point of each side piece is higher than the intermediate piece. The two side pieces and the intermediate piece are combined to form a notch for accommodating a patient's head. The headrest also includes two limiting components respectively disposed on the two side pieces. Each limiting component includes a rotating shaft rotatably connected to the side piece, a rotating plate fixedly connected to the rotating shaft, and a limiting block disposed on the rotating plate. When the limiting blocks of the two limiting components are located within the notch, the two limiting blocks respectively limit the two sides of the patient's head. When the two limiting blocks are rotated to stand upright, the highest point of the limiting block is higher than the highest point of the side piece.

[0007] Furthermore, the limiting component also includes a limiting unit, which includes a rotating block disposed on the rotating shaft, a groove disposed on the rotating block, a sliding sleeve disposed on the side member, and a pin slidably connected to the sliding sleeve. When the limiting block is in an upright state, the groove faces the pin, and the pin is inserted into the groove to limit the rotation of the rotating shaft.

[0008] Furthermore, the limiting block is arched and made of a soft material.

[0009] Furthermore, the headrest also includes a first pull ring on the side of each of the two side pieces away from the middle piece.

[0010] Furthermore, the headrest also includes a second pull ring disposed between the two side members on the side away from the torso.

[0011] Furthermore, the headrest is detachably connected to the torso via a second Velcro strap.

[0012] Furthermore, the torso includes two pads, namely a first pad and a second pad, which are detachably connected together.

[0013] Furthermore, both the first pad and the second pad are provided with a cover on their inner side, and a zipper is provided on the side wall near the cover, so that the cover can be taken out by opening the zipper.

[0014] Furthermore, the first pad and the second pad are detachably connected by a first Velcro strap.

[0015] The beneficial effects of this utility model are as follows: by rotating the limiting block away from the notch, the limiting block drives the rotating plate to rotate, and the rotating plate drives the rotating shaft to rotate on the side piece, so that the two limiting blocks are in an upright state. At this time, the patient's hands can hold the two limiting blocks, so that the patient has a grip and a support point, ensuring that the patient can maintain the current body position. When the patient does not need to use the limiting block, medical staff can also rotate the limiting block to the notch so that the limiting block provides limiting support on both sides of the patient's head, so as to ensure the patient's comfort.

Detailed Implementation

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[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 positioning pillow for CT-guided lung puncture, such as Figures 1-3As shown, the device includes a headrest 1 and a torso 2 detachably connected to the headrest 1. The headrest 1 includes two side pieces 11 and a soft material intermediate piece 12 connected between the two side pieces 11. The highest point of the side pieces 11 is higher than the intermediate piece 12. A notch 13 for accommodating a patient's head is formed between the two side pieces 11 and the intermediate piece 12. The headrest 1 also includes two limiting components 14 respectively disposed on the two side pieces 11. The limiting components 14 include components that are connected to the headrest 11. The side member 11 is rotatably connected to a rotating shaft 141, a rotating plate 142 is fixedly connected to the rotating shaft 141, and a limiting block 143 is provided on the rotating plate 142; when the limiting blocks 143 of the two limiting components 14 are located in the recess 13, the two limiting blocks 143 respectively limit the two sides of the patient's head; when the two limiting blocks 143 are rotated to stand up, the highest point of the limiting block 143 is higher than the highest point of the side member 11; the limiting block 143 is arched and made of soft material.

[0025] It is understandable that the operator can place the entire positioning cushion on the CT examination table, and the patient can lie on the positioning cushion with their head positioned at the occipital region 1 and their torso at the torso region 2. Specifically, the operator lies flat on the positioning cushion, with the patient's head positioned at the notch 13. Two limiting blocks 143 limit the patient's head on both sides, making the patient's head more comfortably positioned at the notch 13. The intermediate part 12 and the limiting blocks 143 are made of soft sponge, which is elastic and increases patient comfort. When medical staff perform punctures on the patient, the patient's arms are usually raised to achieve the correct positioning. At this time, the medical staff can rotate the limiting blocks 143 away from the notch 13. The limiting blocks 143 drive the rotating plate 142 to rotate, and the rotating plate 142 drives the rotating shaft. 141 rotates on the side piece 11, thereby putting the two limiting blocks 143 in an upright state. At this time, the patient's hands can grasp the two limiting blocks 143, thus providing the patient with a grip and support point to ensure that the patient can maintain the current body position. When the patient does not need to use the limiting blocks 143, medical staff can also rotate the limiting blocks 143 to the notch 13, so that the limiting blocks 143 provide limiting support on both sides of the patient's head to ensure the patient's comfort. Furthermore, the headrest 1 and the torso 2 are detachably connected, allowing medical staff to separate the headrest 1 and the torso 2 for independent use. Specifically, the headrest 1 and the torso 2 are detachably connected by the second Velcro 3. Both the headrest 1 and the torso 2 are made of non-magnetic materials to avoid interference with the CT equipment.

[0026] like Figure 3As shown, the limiting component 14 further includes a limiting unit, which includes a rotating block 144 disposed on the rotating shaft 141, a groove 147 disposed on the rotating block 144, a sliding sleeve 145 disposed on the side member 11, and a pin 146 slidably connected to the sliding sleeve 145. When the limiting block 143 is in an upright state, the groove 147 is directly opposite the pin 146, and the pin 146 is inserted into the groove 147 to limit the rotation of the rotating shaft 141.

[0027] It is understandable that when medical staff erect the limiting block 143, the groove 147 and the pin 146 are aligned. The medical staff can slide the pin 146 to insert it into the groove 147. Due to the restriction of the pin 146, the rotating block 144 cannot rotate, thus preventing the rotating shaft 141 from rotating. Consequently, the limiting block 143 will be fixed in the erected state, preventing the limiting block 143 from shaking when the patient's hand grasps it, thus avoiding unstable gripping. When it is necessary to rotate the limiting block 143 into the recess 13, the operator can remove the pin 146 from the groove 147 and then rotate the limiting block 143 into the recess 13.

[0028] like Figure 2 As shown, the headrest portion 1 further includes: a first pull ring 15 is provided on the side of each of the two side pieces 11 away from the middle piece 12.

[0029] It is understandable that when a patient's body shape makes it difficult to grasp the limiting block 143, the patient can grasp the first pull ring 15, thus providing an adaptation scenario.

[0030] like Figure 2 As shown, the headrest portion 1 further includes a second pull ring 16 disposed between the two side pieces 11 on the side away from the torso 2.

[0031] Understandably, when the patient needs to raise both hands higher, the patient can hold the second pull ring 16 to provide support.

[0032] like Figure 4 As shown, the torso 2 includes two pads, namely a first pad 21 and a second pad 22, which are detachably connected together.

[0033] The first pad 21 and the second pad 22 are detachably connected by the first Velcro 23. When the patient needs to lie on their side, the medical staff can separate the first pad 21 and stack the two pads together. When the patient lies on their side on the CT examination bed, the height of the two pads increases because they are stacked together, and the patient's legs can be placed on the top pad, thus ensuring the patient's comfort. When the patient needs to lie flat, the two pads can simply be connected together by the first Velcro 23.

[0034] like Figure 4 As shown, both the first pad 21 and the second pad 22 are provided with covers on their inner sides, and a zipper 24 is provided on the side wall near the cover. The cover can be removed by pulling open the zipper 24.

[0035] It is understandable that when a patient's private parts are exposed or feel cold, medical staff can open the zipper 24, take out the cover from the first pad 21 and the second pad 22, and then cover the patient with the cover.

[0036] In summary, by rotating the limiting block 143 away from the notch 13, the limiting block 143 drives the rotating plate 142 to rotate, and the rotating plate 142 drives the rotating shaft 141 to rotate on the side piece 11, thereby putting the two limiting blocks 143 in an upright state. At this time, the patient's hands can grasp the two limiting blocks 143, thus giving the patient a grip and support point, ensuring that the patient can maintain the current body position. When the patient does not need to use the limiting block 143, medical staff can also rotate the limiting block 143 to the notch 13, so that the limiting block 143 provides limiting support on both sides of the patient's head to ensure the patient's comfort.
