Description

Technical Field

[0001] The utility model relates to the technical field of protective pads, and particularly relates to a radionuclide therapy protective pad. Background Art

[0002] Radionuclide therapy is particularly suitable for the treatment of superficial skin diseases such as keloids and infantile capillary hemangiomas, and it has become a commonly used treatment method in the nuclear medicine department. During the process of radionuclide therapy, it is necessary to first stick a protective pad on the normal skin around the treatment site, and then stick the radionuclide applicator to the treatment site. The protective pad is generally made of a rubber sheet, and its function is to protect the normal skin around the treatment site and prevent radioactive nuclides from damaging the normal skin.

[0003] The commonly used protective pads in clinics are mainly rubber sheets with a hole adapted to the radionuclide applicator opened in the middle. For example, a utility model with a publication number of CN2614045Y discloses a positioning device for a radioactive nuclide skin applicator, which includes a positioning plate and a bottom film. The positioning plate is made of a black rubber plate, and the bottom film is made of an opaque white plastic film. The positioning plate and the bottom film are provided with guide grooves. In addition to positioning the radionuclide applicator through the guide grooves, the bottom film and the positioning plate can also play a role in radiation protection for the surrounding normal skin. Since these protective pads are relatively smooth, they are easy to slide when pasted on the skin, resulting in inconvenient use. For another example, a utility model with a publication number of CN217311607U discloses a special protective rubber pad for hemangioma radionuclide therapy. An anti-slip rubber pad is fixedly connected to the outer surface of the rubber pad. The rubber pad and the anti-slip rubber pad are both provided with openings, and the outer surface of the anti-slip rubber pad is provided with rubber particles to increase the friction with the skin. One side of the outer surface of the rubber pad is provided with two rectangular rubber grooves, and the inner walls of the two rectangular rubber grooves are provided with adhesive tapes. One end of the adhesive tape is pasted in the rectangular rubber groove, and the other end is pasted on the skin, thereby achieving a fixing effect. This type of protective rubber pad can prevent sliding by increasing friction and adhesive tapes.

[0004] However, the sizes of the guide grooves or openings in the above various protective pads are fixed, that is, one protective pad can only be suitable for one specification of radionuclide applicator. In fact, in clinics, it is often necessary to use various radionuclide applicators with different sizes and specifications. This requires corresponding protective pads with different sizes of guide grooves or openings to be equipped. If the number of protective pads is large, it will cause messy storage and inconvenient searching, bringing more inconvenience to the management and use of protective pads.

[0005] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a radionuclide therapy protection pad, so as to overcome the drawback that the existing protection pad can only be applicable to a radionuclide applicator of one specification, which brings a lot of inconvenience to the management and use of the protection pad.

[0025] The following will describe in detail the specific embodiments of the present utility model in conjunction with the drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

[0026] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0027] Figures 1 to 2 shows a schematic structural view of a radionuclide therapy protective pad according to a preferred embodiment of the present utility model. The radionuclide therapy protective pad includes a bottom pad 1 and a hole pad 2. Refer to Figure 2, the material of the bottom pad 1 is rubber. A bottom pad cavity 11 is recessed on the upper surface of the bottom pad 1. A positioning hole 12 is provided on the bottom wall of the bottom pad cavity 11. The positioning hole 12 penetrates through the bottom wall of the bottom pad cavity 11, so that the bottom pad 1 is vertically penetrated at the positioning hole 12. After the bottom pad 1 is attached to the patient's skin, it is necessary to align the positioning hole 12 with the part to be treated on the patient's skin, and the bottom pad 1 covers the surrounding normal skin for protection.

[0028] Reference Figure 1 , the material of the hole pad 2 is also rubber. A number of applicator holes 21 of different sizes are provided on the hole pad 2. The size of each applicator hole 21 corresponds to the size of an applicator of a certain specification, and the positioning hole 12 is not smaller than the largest applicator hole 21, that is, the positioning hole 12 can be the same size as the largest applicator hole 21 or larger than the largest applicator hole 21. The hole pad 2 is movably placed in the bottom pad cavity 11, and the hole pad 2 can be adjusted so that any one of the applicator holes 21 is aligned with the positioning hole 12. And when any one of the applicator holes 21 is aligned with the positioning hole 12, the other applicator holes 21 are blocked by the bottom wall of the bottom pad cavity 11 to prevent the skin from being exposed due to two applicator holes 21 being located above the positioning hole 12 at the same time. By selecting which applicator hole 21 is aligned with the positioning hole 12, the bottom pad 1 and the hole pad 2 can be used as the protective pads of the nuclide applicator of the corresponding specification. Preferably, the positioning hole 12 is larger than the largest applicator hole 21, and the size of the positioning hole 12 corresponds to the size of an applicator of a certain specification. In this way, without using the hole pad 2, the bottom pad 1 can be directly used as the protective pad of a nuclide applicator of a certain specification to increase the applicability.

[0029] Reference Figure 1 and Figure 2, further, in the present utility model, the bottom pad cavity 11 is a circular cavity, the hole pad 2 is a circular pad corresponding to the bottom pad cavity 11, and after the hole pad 2 is placed into the bottom pad cavity 11, the two are coaxially distributed. The positioning hole 12 is eccentrically arranged on the bottom wall of the bottom pad cavity 11; all the applicator holes 21 are located on a circumference with the same center on the axis of the hole pad 2, and the distance between the center line of the positioning hole 12 and the center line of the bottom pad cavity 11 is equal to the distance between the center line of the applicator hole 21 and the axis of the hole pad 2. In this way, the hole pad 2 can adjust the alignment of different applicator holes 21 with the positioning hole 12 of the bottom pad cavity 11 by rotation, and the adjustment is simple and convenient. Preferably, there are four applicator holes 21 provided on the hole pad 2, and the four applicator holes 21 are evenly distributed along the same circumference. In this way, one hole pad 2 can be applicable to four different radionuclide applicators. After adjusting the positions of the bottom pad 1 and the hole pad 2 on the patient's skin, multiple adhesives can be further used for fixation. One end of the adhesive is simultaneously pasted on the hole pad 2 and the bottom pad 1, and the other end is pasted on the patient's skin. Preferably, at least a pair of U-shaped handles 22 are provided at the edge of the hole pad 2, and the U-shaped handles 22 protrude upward. By holding the U-shaped handles 22 with hands, the hole pad 2 can be taken and placed, and the hole pad 2 can also be rotated. In addition, when the adhesive needs to be fixed, one end of the adhesive can also be wound and fixed on the U-shaped handle 22, making the adhesive more firm and reliable. Therefore, after adding the U-shaped handles 22, it is convenient to rotate the hole pad 2 and also convenient to wind and fix one end of the adhesive, thereby facilitating the fixation of the protective pad to the patient's skin. Further preferably, several pairs of adhesive slots 13 are provided on the side wall of the bottom pad cavity 11. When any one of the applicator holes 21 is aligned with the positioning hole 12, at least a pair of U-shaped handles 22 are aligned with a pair of adhesive slots 13. In this way, after one end of the adhesive is fixed on the U-shaped handle 22, this end can also be simultaneously pasted in the adhesive slot 13, which not only limits the adhesive by the adhesive slot 13, but also reduces the height of this end of the adhesive to reduce the length of the adhesive suspension and increase the acting area between the adhesive and the bottom pad 1.

[0030] When the present utility model is in use, first, according to the size of the part to be treated on the patient's skin, a radionuclide applicator with a suitable size specification is selected. Then, the bottom pad 1 is placed on the patient's skin and the positioning hole 12 is aligned with the part to be treated. Next, the corresponding-sized applicator holes 21 on the hole pad 2 are aligned with the positioning hole 12, and then multiple adhesives are used to fix the bottom pad 1 and the hole pad 2. The radionuclide applicator can pass through the applicator holes 21 and the positioning hole 12 to be pasted on the part to be treated on the skin for radionuclide treatment. During treatment, the upper end surface of the radionuclide applicator can be higher than the bottom surface of the hole pad 2 to cover the applicator holes 21. The hole pad 2 of the present utility model is provided with several applicator holes 21. By adjusting the hole pad 2, different applicator holes 21 can be aligned with the positioning hole 12 of the bottom pad cavity 11, so as to be applicable to radionuclide applicators of different size specifications. In this way, multiple radionuclide applicators can share one protective pad, greatly reducing the number of protective pads that need to be equipped in clinical practice, thus facilitating management and use.
