Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular to a breathable positioning patch for CT scans. Background Technology
[0002] The breathable CT scan positioning tape, also known as the CT-guided puncture biopsy positioning tape, consists of a thin film of acrylic with a copper sheet sandwiched in it. The film has multiple holes on its surface. The method of use is as follows: First, cut a piece of positioning tape larger than the area to be scanned on the patient from a roll of tape. Then, cover the patient with the positioning tape and fix it with adhesive tape. Then, perform the scan. After the scan is completed, mark the points that need to be punctured and biopsied at the corresponding holes on the positioning tape for subsequent puncture biopsies.
[0003] However, each time the positioning sticker is applied, the adhesive tape needs to be prepared in advance, which means that one person needs to hold the positioning sticker down while the other person applies the tape. If the two people do not coordinate well, it will make it very troublesome to fix the positioning sticker. Therefore, a breathable positioning sticker for CT scans is needed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a breathable positioning sticker for CT scanning, so as to solve the technical problem that the fixing of positioning stickers in the prior art is very troublesome.
[0005] The above-mentioned objective of this application is achieved through the following technical solution: a breathable positioning patch for CT scanning, comprising two rolls and a puncture positioning patch with both ends fixed to the two rolls respectively. The puncture positioning patch is wound on the two rolls, and a rotating shaft rotatably connected to the rolls extends from the axis of each of the two rolls. Fixing structures for medical personnel to easily fix the puncture positioning patch are installed at both ends of the rotating shaft.
[0006] Furthermore, the fixing structure includes two extension rods respectively fixedly connected to both ends of the rotating shaft, a take-up box located between the two extension rods and fixedly connected to the extension rods, and a roll of adhesive tape placed in the take-up box. The take-up box has an opening on the side away from the roll for the adhesive tape roll to extend out, and the length of the opening is longer than the puncture positioning tape.
[0007] By adopting the above technical solution, the puncture positioning patch is extended by pulling two rolls, then pressed onto the patient's body, and then the tape roll extending from the opening is pulled, so that the tape on the tape roll sticks to the puncture positioning patch and the two ends of the tape stick to the patient's body. In this way, the puncture positioning patch can be fixed. A single person can fix the puncture positioning patch to the patient's body, making it more convenient for medical staff to fix the puncture positioning patch.
[0008] Furthermore, the winding box has extended flanges on both sides, and the extended flanges are equipped with cutting structures for cutting the adhesive tape roll and piercing the positioning tape.
[0009] Furthermore, the cutting structure includes a portal frame with its two ends fixedly connected to two extending flanges, and a cutting blade inserted into the portal frame on the side away from the extending flanges and passing through the portal frame.
[0010] While the above-mentioned technical solution makes it easier for medical staff to fix the puncture positioning tape, it also restricts their movement space between the two rolls when cutting the tape roll and the puncture positioning tape, making it inconvenient for them. The cutting structure solves this problem. After the tape roll fixes the puncture positioning tape, the cutting blade is pressed down to cut the tape roll and the puncture positioning tape, making it easier for medical staff to cut them.
[0011] Furthermore, limiting flanges are fixedly provided on both sides of the upper end of the cutting blade to prevent the cutting blade from cutting into the patient's skin.
[0012] While the cutting device makes it easier for medical staff to cut adhesive tape rolls and puncture positioning patches, the cutting blade may cut the patient's skin if the medical staff presses it too hard. The limiting flange solves this problem. When the medical staff presses the cutting blade too hard, the limiting flange will abut against the gantry frame to prevent the cutting blade from continuing to descend and cut, thus making it safer for medical staff to use the cutting blade.
[0013] Furthermore, a reset spring for resetting the cutting blade is provided between the limiting flange and the gantry frame. One end of the reset spring is fixedly connected to the bottom surface of the limiting flange, and the other end is fixedly connected to the gantry frame.
[0014] The above technical solution means that after the cutting blade is pressed down, medical staff need to lift it up before using it again, which is very inconvenient. The reset spring solves this technical problem. When the cutting blade is pressed down, it compresses. When the pressing force is removed, the reset spring pushes against the limiting flange to reset the cutting blade, making it more convenient for medical staff to use the cutting blade.
[0015] Furthermore, one side of the extension rod has an opening that connects to the inside of the winding box, and a plug is provided inside the opening to seal it.
[0016] By adopting the above technical solution, when it is necessary to replace the tape roll, simply pull out the stopper and insert the new tape roll into the take-up box, making tape roll replacement more convenient.
[0017] Furthermore, the stopper has a handle on the side away from the winding box.
[0018] By adopting the above technical solution, the handle is made easier for medical staff to pull the plug.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] By setting up a fixed structure, the puncture positioning tape can be extended by pulling two rolls, then pressed onto the patient's body, and then the tape roll extending from the opening can be pulled to stick the tape on the puncture positioning tape and make the two ends of the tape stick to the patient's body. This can fix the puncture positioning tape to the patient's body by a single person, making it more convenient for medical staff to fix the puncture positioning tape. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.
[0025] Example, refer to Figure 1 , Figure 2 A breathable positioning patch for CT scans comprises two rolls 1 and a puncture positioning patch 10 fixed at both ends to the two rolls 1. When not in use, the puncture positioning patch 10 can be neatly rolled up and stored on the two rolls 1, saving space and making it easy to carry. A rotating shaft 11 extends from the central axis of each of the two rolls 1, and these rotating shafts 11 are rotatably connected to the rolls 1, ensuring smooth rotation of the rolls 1.
[0026] At both ends of the rotating shaft 11, a fixing structure 2 is provided to help medical staff easily fix the puncture positioning tape 10. This fixing structure 2 consists of several key parts: First, there are two extension rods 20 that are firmly connected to both ends of the rotating shaft 11, which serve to support and extend the fixing structure 2; second, there is a retractable box 21 located between the two extension rods 20 and fixedly connected to them, which provides a neat and safe storage space for the items inside; finally, there is a roll of adhesive tape 22 placed inside the retractable box 21.
[0027] On the outside of the take-up cassette 21, on the side away from the roll 1, there is an opening specifically designed for the tape roll 22. The length of this opening is intentionally set to be slightly longer than the puncture positioning sticker 10, to ensure that the tape on the tape roll 22 can smoothly extend from the take-up cassette 21 and has sufficient length to cover and fix the puncture positioning sticker 10.
[0028] In practical use, medical staff can easily unfold the puncture positioning patch 10 by simply pulling the two rolls 1. They can then press the unfolded patch 10 flat onto the patient's body, ensuring a tight fit and accurate positioning. Next, the medical staff can gently pull the adhesive tape roll 22 extending from the opening to easily cover the puncture positioning patch 10 with adhesive tape, which, with its stickiness, firmly fixes the patch 10 to the patient's body. Simultaneously, both ends of the tape can be directly adhered to the patient's skin, further enhancing the stability of the fixation.
[0029] In this way, even if only one medical staff member is present, the fixation of the puncture positioning patch 10 can be completed easily and quickly, which greatly improves work efficiency and provides more convenience for medical staff.
[0030] While the fixing structure 2 makes it easier for medical staff to fix the puncture positioning patch 10, it also restricts their movement space between the two rolls 1 when cutting the tape roll 22 and the puncture positioning patch 10, making it inconvenient for them. To solve this technical problem, this embodiment provides extending flanges 23 on both sides of the winding box 21. Cutting structures 3 for cutting the tape roll 22 and the puncture positioning patch 10 are installed on the extending flanges 23. The cutting structure 3 includes a portal frame 30 with its two ends fixedly connected to two extending flanges 23, and a cutting blade 31 inserted into the side of the portal frame 30 away from the extending flanges 23 and passing through the portal frame 30. With the setting of the cutting structure 3, after the adhesive tape roll 22 fixes the puncture positioning patch 10, the cutting blade 31 is pressed down to cut the adhesive tape roll 22 and the puncture positioning patch 10, which makes it more convenient for medical staff to cut the adhesive tape roll 22 and the puncture positioning patch 10.
[0031] Although the cutting device makes it easier for medical staff to cut the tape roll 22 and the puncture positioning patch 10, the cutting blade 31 may cut the patient's skin if the medical staff presses it too hard. To solve this technical problem, this embodiment has limiting flanges 32 fixed on both sides of the upper end of the cutting blade 31 to prevent the cutting blade 31 from cutting the patient's skin. With the setting of the limiting flanges 32, when the medical staff presses the cutting blade 31 too hard, the limiting flanges 32 will abut against the gantry frame 30 to prevent the cutting blade 31 from continuing to descend and cut, thereby making it safer for medical staff to use the cutting blade 31.
[0032] In this embodiment, after the cutting blade 31 is pressed down, medical staff need to lift the cutting blade 31 before using it again, which is very inconvenient. To solve this technical problem, this embodiment provides a reset spring 33 between the limiting flange 32 and the gantry frame 30 to reset the cutting blade 31. One end of the reset spring 33 is fixedly connected to the bottom surface of the limiting flange 32, and the other end is fixedly connected to the gantry frame 30. By setting the reset spring 33, the reset spring 33 will be compressed when the cutting blade 31 is pressed down. When the pressing force is removed, the reset spring 33 will push against the limiting flange 32 to reset the cutting blade 31, making it more convenient for medical staff to use the cutting blade 31.
[0033] In this embodiment, an opening is provided on one side of the extension rod 20 to connect to the inside of the take-up box 21. A plug 4 is provided in the opening to block the opening, and a handle 40 is provided on the side of the plug 4 away from the take-up box 21. When it is necessary to replace the tape roll 22, the plug 4 can be pulled out and a new tape roll 22 can be inserted into the take-up box 21, making the replacement of the tape roll 22 more convenient.
[0034] Specific implementation process: Pull the two rolls 1 to extend the puncture positioning patch 10, then press the puncture positioning patch 10 onto the patient's body, then pull the tape roll 22 that extends from the opening, so that the tape on the tape roll 22 sticks to the puncture positioning patch 10 and the two ends of the tape stick to the patient's body, then press the cutting blade 31 so that the cutting blade 31 cuts the tape roll 22 and the puncture positioning patch 10, so that the puncture positioning patch 10 is fixed on the patient's body.
[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
