Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a developing positioning tape. Background Art

[0002] In the percutaneous puncture positioning technology guided by CT, the developing positioning tape is a key tool that helps doctors accurately determine the location of the lesion. Traditional developing positioning tape is usually composed of non-woven fabric, anti-adhesive paper, pressure-sensitive adhesive and barium sulfate developing line. When using this tape, it needs to be attached to the body surface of the lesion. Through CT scanning, doctors can see the lesion in the image showing the dot-like high-density shadow of the fence locator, so as to accurately locate the puncture.

[0003] However, existing imaging positioning tapes have some technical problems. First, the imaging lines of the tapes are usually thicker, which is to ensure that doctors can clearly see the positioning marks. However, too thick imaging lines will block part of the patient's tissues, resulting in inaccurate measurements on CT images.

[0004] Based on this, in order to further improve the applicability of the existing positioning tape, we propose a developing positioning tape. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art that the developing line is usually thick, resulting in inaccurate measurement on the CT image, and proposes a developing positioning tape.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Design a developing positioning tape, comprising a developing layer, a base layer, an adhesive layer and an anti-adhesive layer;

[0008] The adhesive layer is coated below the base layer, and the anti-sticking layer is attached to the bottom of the adhesive layer;

[0009] Among them, the developing layer includes a plurality of longitudinal lines and a plurality of transverse lines formed on the base layer, and the plurality of longitudinal lines and the plurality of transverse lines together constitute a grid structure, and subdivision marks are also arranged on the longitudinal lines and the transverse lines; the subdivision marks include a plurality of blank portions formed on the longitudinal lines and the transverse lines, and the plurality of blank portions are arranged at predetermined intervals.

[0010] Furthermore, the blank portion extends from the sides of the longitudinal line and the transverse line toward the central axis thereof, and the blank portion is provided on at least one side of each of the longitudinal line and the transverse line.

[0011] Furthermore, the blank portion is one of a rectangular structure, a semicircular structure, a triangular structure or a trapezoidal structure.

[0012] Furthermore, the middle of the adhesive layer has a plurality of adhesive overflow holes.

[0013] Furthermore, the base layer is a non-woven fabric layer.

[0014] The utility model proposes a developing positioning tape, which has the beneficial effect that: the innovative design of the blank part in the utility model can reduce the width of the developing line to improve the measurement accuracy, and at the same time, it can also be used as a small scale in each small grid of the grid structure. Medical personnel can easily make a more accurate judgment on the size of the patient in a single grid by calculating the number of blank parts, which significantly improves the measurement accuracy in clinical applications and provides a more reliable guarantee for the diagnosis and treatment of patients.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 An embodiment of the utility model discloses a developing positioning tape, which is used to solve the problem that the developing line of the current developing tape is too wide, affecting the measurement accuracy. Specifically, the positioning tape includes a developing layer 1, a base layer 2, a glue layer 3 and an anti-sticking layer 4. As a preferred embodiment, the developing layer 1 in this embodiment is a barium sulfate developing line, and the glue layer 3 is a pressure-sensitive glue layer;

[0021] The adhesive layer 3 is coated below the base layer 2, and the anti-sticking layer 4 is attached to the bottom of the adhesive layer 3;

[0022] The developing layer 1 includes a plurality of longitudinal lines 11 and a plurality of transverse lines 12 formed on the base layer 2 . The plurality of longitudinal lines 11 and the plurality of transverse lines 12 together form a grid structure. Subdivision marks 13 are also provided on the longitudinal lines 11 and the transverse lines 12 .

[0023] In some embodiments, the subdivision mark 13 in the present invention includes a plurality of blank portions formed on the longitudinal line 11 and the transverse line 12 , and the plurality of blank portions are arranged at predetermined intervals.

[0024] In a specific embodiment, the design of the blank portion cleverly utilizes the existing line structure to create multiple functional blank areas. This design has dual advantages: on the one hand, it effectively reduces the line width of the longitudinal line 11 and the transverse line 12, making the overall tape more delicate and easy to observe and operate;

[0025] On the other hand, during the imaging positioning measurement process, the traditional grid structure tape can only roughly estimate the size of the patient's part by the number of small grids, and cannot accurately measure the detailed size within a single grid. The utility model introduces multiple blank parts, each of which can be used as a small scale, greatly improving the measurement accuracy. For example, the distance between each two blank parts is set to 0.2MM, so that during imaging positioning, medical staff can easily make a more accurate judgment on the size of the patient within a single grid by calculating the number of blank parts.

[0026] In summary, the utility model not only optimizes the visual effect of the developing positioning tape through the innovative design of the blank part, but also significantly improves its measurement accuracy in clinical applications, providing a more reliable guarantee for the diagnosis and treatment of patients.

[0027] Preferably, the blank portion in the present embodiment extends from the sides of the longitudinal line 11 and the transverse line 12 toward the central axis thereof, and the blank portion is provided on at least one side of each of the longitudinal line 11 and the transverse line 12, that is, the blank portion in the present embodiment extends to the sides of the longitudinal line 11 and the transverse line 12, thereby achieving the goal of reducing the line width while further improving the observation of the patient.

[0028] It should be noted that the blank portion in this embodiment is a rectangular structure, a semicircular structure, a triangular structure or a trapezoidal structure. Figure 2 As shown, the blank portion described in this embodiment is preferably set as a rectangular structure. Of course, technical personnel in the relevant field know that the above-mentioned structures can be combined or further changed and replaced. Equivalent structures are all within the protection scope of the present utility model and will not be described in detail here.

[0029] It should be noted that the base layer 2 in this embodiment is a non-woven fabric layer. In addition, the middle part of the adhesive layer 3 has a plurality of overflow holes 31. In this embodiment, a plurality of overflow holes 31 are reserved in the glue coating process. When the adhesive tape is actually used, when the adhesive layer 3 is attached to the human body, the overflow holes 31 can reserve a certain space to avoid overflow of the adhesive layer. Furthermore, the overflow holes 31 can also be used as exhaust holes. As mentioned above, since the base layer 2 adopts a non-woven fabric layer structure, the overflow holes 31 are connected to the base layer 2. With the help of the certain air permeability of the non-woven fabric, when the adhesive tape is attached, the air between the adhesive tape and the skin can be discharged outward through the overflow holes 31 and the non-woven fabric. This avoids bulging during the adhesion process, which affects the measurement accuracy, so as to achieve the purpose of better adhesion of the entire adhesive tape and stronger adhesion after adhesion.

[0030] In summary, the innovative design of the blank part adopted in the utility model can reduce the width of the development line to improve the measurement accuracy, and at the same time, it can also be used as a small scale in each small grid of the grid structure. Medical personnel can easily make a more accurate judgment on the size of the patient in a single grid by calculating the number of blank parts, which significantly improves the measurement accuracy in clinical applications and provides a more reliable guarantee for the diagnosis and treatment of patients.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
