Description

Technical Field

[0001] This utility model relates to the field of Strontium-90, and more particularly to a Strontium-90 therapeutic surface fixation band. Background Technology

[0002] Strontium-90, with the nuclide symbol 90Sr and a half-life of 28.79 years, is a beta radiator. It is commonly used in medical treatment as a strontium patch, primarily utilizing the beta rays it emits to slow down the growth and division of keratinocytes, even causing them to degenerate, die, and eventually slough off, thus achieving a therapeutic effect. The strontium-90 patch applicator is the most important treatment device in strontium patch therapy. Due to its radioactivity, it is distributed to patients by hospitals, which will provide the appropriate strontium-90 patch applicator based on the size and shape of the lesion.

[0003] Strontium-90 applicators are generally square or round, with a cylindrical handle at the top. During treatment, the patient holds the handle and applies the Strontium-90 applicator to the lesion site, then removes it after a period of time. However, lesions vary in location and are widely distributed across the body. When the lesion site is in a difficult-to-reach location, or when the patient is unable to hold the applicator for an extended period due to physical limitations, the treatment is often difficult to complete. Therefore, there is an urgent need for a surface fixation band for Strontium-90 treatment to help patients complete the treatment procedure when they cannot hold the applicator for an extended period or when the lesion site is in a difficult-to-reach location. Utility Model Content

[0004] To address the problem in existing technologies where patients struggle to complete treatment when the lesion is located in a difficult-to-access area or when they are unable to perform handheld treatment for an extended period due to physical inconvenience, this invention provides a strontium-90 treatment surface fixation strap.

[0005] The strontium-90 therapeutic surface fixation bandage provided by this utility model adopts the following technical solution:

[0006] A strontium-90 therapeutic surface fixation band includes a strontium-90 applicator body and a base. The base has a through-hole at its top, and a transparent partition is provided at the bottom of the hole. A fixing seat is fitted onto the top of the strontium-90 applicator body, allowing the body to be detachably mounted within the hole via the fixing seat. The base has a tightening chamber inside, with a limiting plate at its top. One end of a shaft is rotatably connected to the bottom of the chamber, and the other end of the shaft passes through the limiting plate and is fixedly connected to a rotating block. One end of a tightening strap is fixedly connected to the circumferential sidewall of the shaft, and the other end of the strap passes through the sidewall of the tightening chamber and is fixedly connected to the outer sidewall of the base. A limiting pin is movably connected inside the rotating block, and the pin engages with the limiting plate to fix the position of the rotating block.

[0007] Furthermore, the fixing base includes an annular cap and snap-fit ​​posts. The top of the annular cap has a through hole, through which the annular cap can be fitted onto the top of the S90 applicator body. The opposite sides of the annular cap are integrally formed with symmetrical snap-fit ​​posts. The sides of the mounting hole have slots, and the snap-fit ​​posts and slots are detachably engaged.

[0008] Furthermore, the slot is L-shaped, and the inside of the snap-fit ​​post is provided with a receiving groove. One end of a fixing spring is fixedly connected to the inner side wall of the receiving groove, and the other end of the fixing spring is fixedly connected to a fixing pin. The fixing pin is C-shaped, and both ends of the fixing pin can pass through the side wall of the receiving groove and extend outside the receiving groove.

[0009] Furthermore, the surface of the limiting plate is provided with several prisms, the inside of the rotating block is provided with a limiting groove, one end of a limiting spring is fixedly connected to the inner side wall of the limiting groove, the other end of the limiting spring is fixedly connected to a limiting pin, the limiting pin is L-shaped, a sliding groove is provided at the top of the limiting groove, and the top of the limiting pin passes through the sliding groove and extends outside the sliding groove.

[0010] Furthermore, the cross-section of the prism is triangular, and several of the prisms are arranged in a circular array on the surface of the limiting disk. The end of the limiting pin that contacts the prism forms a driving inclined surface.

[0011] Furthermore, the partition is made of transparent glass or acrylic.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] This invention, through the design of a shaft, limiting plate, tightening band, and limiting pin, allows the base to fit tightly and securely against the patient's skin, effectively preventing the patch from falling off or shifting. Simultaneously, the tightening band can be flexibly adjusted according to the patient's lesion location and physical condition, enhancing flexibility. The installation and removal of the patch via a simple snap-fit ​​connection, achieved through a fixed base and slot, greatly simplifies the operation process and reduces the difficulty of use. The prism design on the limiting plate surface, combined with the limiting groove and limiting pin inside the rotating block, allows medical personnel to easily adjust the tightness of the tightening band, and the automatic locking function of the limiting pin ensures stability after adjustment.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be further described in detail below:

[0022] This utility model discloses a strontium-90 therapeutic surface fixation band, such as... Figure 1 , Figure 3As shown, this utility model discloses a Strontium 90 therapeutic surface fixation band, comprising a Strontium 90 patch body 1 and a base 2. The top of the base 2 has a through-hole 3, and the bottom of the mounting hole 3 has a transparent partition 4. A fixing seat 5 is fitted onto the top of the Strontium 90 patch body 1, and the Strontium 90 patch body 1 is detachably mounted within the mounting hole 3 via the fixing seat 5. The base 2 has a tightening chamber 6 inside, and a limiting plate 7 is provided at the top of the tightening chamber 6. One end of a shaft 61 is rotatably connected to the bottom of the tightening chamber 6, and the other end of the shaft 61 passes through... The limiting disc 7 is fixedly connected to a rotating block 8. One end of a tightening strap 62 is fixedly connected to the circumferential side wall of the shaft 61. The other end of the tightening strap 62 passes through the side wall of the tightening chamber 6 and is fixedly connected to the outer side wall of the base 2. A limiting pin 81 is movably connected inside the rotating block 8. The limiting pin 81 can cooperate with the limiting disc 7 to fix the position of the rotating block 8. In this embodiment, since the Sr. 90 patch body 1 is generally directly distributed by the hospital and is commonly square or round, the shape and size of the mounting hole 3 should match the shape and size of the Sr. 90 patch body 1. Preferably, the partition 4 is made of transparent glass or acrylic. This has the advantage of not blocking the β-rays of the patch from acting on the lesion site. By setting the shaft 61, limiting disc 7, tightening strap 62, and limiting pin 81, the base 2 can be tightly attached to and fixed to the patient's body surface, effectively preventing the patch from falling off or shifting. Meanwhile, the tightening band 62 can be flexibly adjusted according to the patient's lesion location and physical condition, enhancing its flexibility. It is worth noting that the width of the tightening band 62 is adjustable; widening the tightening band 62 can enhance its fixation effect.

[0023] like Figure 2 As shown, the fixing base 5 includes an annular cap 51 and snap-fit ​​posts 52. The top of the annular cap 51 has a through hole, through which the annular cap 51 can be fitted onto the top of the Sr.90 applicator body 1. Symmetrical snap-fit ​​posts 52 are integrally formed on opposite sides of the annular cap 51. Slots 53 are formed on both sides of the mounting hole 3, and the snap-fit ​​posts 52 and slots 53 are detachably engaged. In this embodiment, the shape of the annular cap 51 is as follows: Figure 2 As shown, the handle of the Sr.90 applicator body 1 can be inserted into the ring cap 51, and the ring cap 51 and the partition plate 4 fix the applicator in the mounting hole 3. The snap-fit ​​post 52 and the slot 53 can be matched in various ways. The snap-fit ​​post 52 and the slot 53 can also be detachably snapped together by interference fit, as long as the Sr.90 applicator body 1 can be fixed.

[0024] like Figure 5 , Figure 6As shown, the slot 53 is L-shaped, and the inside of the locking post 52 has a receiving groove 54. One end of a fixing spring 55 is fixedly connected to the inner side wall of the receiving groove 54, and the other end of the fixing spring 55 is fixedly connected to a fixing pin 56. The fixing pin 56 is C-shaped, and both ends of the fixing pin 56 can pass through the side wall of the receiving groove 54 and extend outside the receiving groove 54. In this embodiment, the shapes of the slot 53 and the fixing pin 56 are as follows: Figure 6 As shown, after the snap-fit ​​pin 52 and the slot 53 are engaged, one end of the fixing pin 56 will enter the interior of the L-shaped slot 53, and the other end of the fixing pin 56 will be on the upper side of the slot 53. Pressing the end of the fixing pin 56 on the upper side of the slot 53 will cause the fixing pin 56 to enter the receiving groove 54. At this time, the fixing seat 5 can be connected / contacted with the slot 53.

[0025] like Figure 2 , Figure 4 As shown, the surface of the limiting disc 7 is provided with several prisms 71. The inside of the rotating block 8 is provided with a limiting groove 82. One end of a limiting spring 83 is fixedly connected to the inner side wall of the limiting groove 82, and the other end of the limiting spring 83 is fixedly connected to a limiting pin 81. The limiting pin 81 is L-shaped, and a sliding groove 84 is provided at the top of the limiting groove 82. The top of the limiting pin 81 passes through the sliding groove 84 and extends outside the sliding groove 84. In this embodiment, the end of the limiting pin 81 can be engaged with the prisms 71 on the surface of the limiting disc 7. In use, the patient wraps the tightening band 62 around the body surface according to the lesion location, rotates the rotating block 8 to tighten the tightening band 62, and after tightening, the limiting pin 81 will be engaged with the prisms 71 on the surface of the limiting disc 7 to complete the fixation.

[0026] like Figure 4 As shown, the cross-section of the prism 71 is triangular, and several prisms 71 are arranged in a circular array on the surface of the limiting disk 7. The end of the limiting pin 81 that contacts the prism 71 forms a driving inclined surface 811. In this embodiment, the shapes of the prism 71 and the limiting pin 81 are as follows: Figure 4 As shown, the cross-section of the driving inclined surface 811 at the end of the limiting pin 81 is a triangle that matches the prism 71. When tightening the strap 62, rotating the rotating block 8 clockwise causes the limiting pin 81 to slide on the surface of the prism 71 and compress the limiting spring 83. When the limiting pin 81 reaches the next prism 71, it will pop out under the action of the limiting spring 83 and lock onto the next prism 71. Because the limiting pin 81 matches the prism 71, the rotating block 8 will be locked when rotating counterclockwise, thus achieving unidirectional adjustment when tightening the strap 62.

[0027] The implementation principle of this utility model embodiment is as follows:

[0028] First, insert the S 90 applicator body 1 into the ring cap 51, press the fixing pin 56 at the upper end of the slot 53 and insert the snap pin 52 into the slot 53 and then release it to fix the S 90 applicator body 1 in the mounting hole 3.

[0029] Then, align the Sr. 90 patch body 1 in the mounting hole 3 with the patient's lesion area, wrap the tight band 62 around the patient's body surface, and rotate the rotating block 8 clockwise to tighten the tight band 62. The limiting pin 81 will slide on the surface of the prism 71 and compress the limiting spring 83. When the limiting pin 81 reaches the next prism 71, it will pop out under the action of the limiting spring 83 and lock onto the next prism 71. Because the human body will squeeze the tight band 62, the tight band 62 will be tightened. Through the cooperation of the limiting pin 81 and the limiting plate 7, the tightened tight band 62 is fixed. Therefore, the base 2 can fit closely to the patient's body surface and be fixed.
