Description

Technical fields:

[0001] This utility model relates to the field of medical radiation protective clothing technology, and in particular to a staggered sewing structure that can prevent radiation leakage and a medical radiation protective clothing. Background technology:

[0002] Medical radiation protective clothing, as a primary form of passive medical radiation protection, is essential for the protection of medical personnel and patients. Regardless of the current manufacturing process, the connection between the fabric and the protective material, as well as the reinforcement of the protective material, are always involved. Since the two panels of the protective clothing overlap at the chest using Velcro, and the clothing must be impervious to pinholes to block and absorb radiation, the Velcro is typically attached or sewn onto the inner and outer fabrics, avoiding the middle protective material (which would cause it to become loose between the protective material and the fabric). This allows the Velcro on the inner fabric of the left panel to adhere to the Velcro on the outer fabric of the right panel, maintaining the front coverage and blocking radiation. However, because the protective material is made of lead, rare earth elements, or a mixture of lead and rare earth elements, along with rubber, the weight of the protective clothing reaches 5-10 kg. Therefore, reinforcement is needed under the armpits to prevent the protective material from sagging and breaking after prolonged use. There are currently two reinforcement methods: Method one is the adhesive method, where the protective material and the fabric are pre-bonded together. The inelastic fabric pulls on the elastic protective material, preventing it from being stretched by its own weight. The advantage is that it is easy to process, requiring no sewing and eliminating needle holes. The disadvantage is that the Velcro connecting the left and right pieces can only be adhered to the fabric. As a result, during long-term use of the protective clothing, the Velcro either tears off the fabric or tears the fabric along with the Velcro off the protective material, rendering the entire protective clothing unusable. This method has been largely abandoned in clinical applications. Method two is a through-sewn structure, which includes a three-piece sewn structure and a one-piece sewn structure. The one-piece sewn structure involves first threading the seam from the inside out through the inner fabric layer, the protective material layer, and the outer fabric layer. Then, the seam is offset by a certain distance and threaded from the outside in through the outer fabric layer, the protective material layer, and the inner fabric layer, completing the one-piece reinforcement of the medical radiation protective clothing fabric and protective material. The three-piece sewn structure involves first overlapping the left and rear protective pieces. Then, the stitching proceeds from the inside out, passing through the inner fabric layer, protective material layer, and outer fabric layer of the left protective piece, followed by the inner fabric layer, protective material layer, and outer fabric layer of the rear protective piece. Next, the stitching is offset and then proceeds from the outside in, passing through the outer fabric layer, protective material layer, and inner fabric layer of the rear protective piece, followed by the outer fabric layer, protective material layer, and inner fabric layer of the left protective piece. The right and rear protective pieces are then sewn together in the same manner for reinforcement, completing the connection between the fabric and protective material of the three-piece medical radiation protective suit. Regardless of whether it's a single-piece or three-piece sewn structure, a fully through-sewn structure will inevitably have pinholes through which radiation can leak, reducing the overall protective effect. Therefore, a staggered sewn structure that prevents radiation leakage is urgently needed. Utility Model Content:

[0003] The purpose of this utility model is to provide a staggered sewing structure that can prevent radiation leakage, which addresses the shortcomings of existing technologies. It does not have completely penetrating needle holes, thus preventing radiation leakage and ensuring a more reliable overall protective effect. It is better suited for sewing and connecting medical radiation protective clothing.

[0004] This utility model also provides a medical radiation protective suit, which provides a more reliable overall protective effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a staggered sewing structure and medical radiation protective clothing that can prevent radiation leakage, comprising an inner fabric layer, an inner protective material layer, an outer protective material layer, an outer fabric layer, an inner seam, and an outer seam. The inner fabric layer, the inner protective material layer, the outer protective material layer, and the outer fabric layer are arranged sequentially from the inside to the outside. The inner fabric layer and the inner protective material layer are sewn together by the inner seam, and the outer fabric layer and the outer protective material layer are sewn together by the outer seam. The inner seam and the outer seam are staggered.

[0006] A further improvement to the above solution is that the inner seam includes a first inner segment, a second inner segment, and a third inner segment. The first inner segment passes through the inner fabric layer and the inner protective material layer from the inside out, forming a first inner needle hole. The third inner segment passes through the inner protective material layer and the inner fabric layer from the outside in, forming a second inner needle hole. The second inner segment is located outside the inner protective material layer and between the first and third inner segments. The outer seam includes a first outer segment, a second outer segment, and a third outer segment. The first outer segment passes through the outer fabric layer and the outer protective material layer from the outside in, forming a first outer needle hole. The third outer segment passes through the outer protective material layer and the outer fabric layer from the inside out, forming a second outer needle hole. The second outer segment is located inside the outer protective material layer and between the first and third outer segments. The first inner needle hole, the second inner needle hole, the first outer needle hole, and the second outer needle hole are all staggered.

[0007] A further improvement to the above scheme is that there are at least two inner seams and two outer seams.

[0008] A further improvement to the above scheme is that both the inner protective material layer and the outer protective material layer include at least two protective sheets, with the protective sheets of the inner protective material layer arranged sequentially from the inside out, and the protective sheets of the outer protective material layer arranged sequentially from the inside out.

[0009] A further improvement to the above scheme is that the lead equivalent of the protective sheet is at least 0.125 mmPb.

[0010] A further improvement to the above solution is that the inner protective material layer and the outer protective material layer respectively include a large protective sheet and a small protective patch, and the inner seam and the outer seam are respectively sewn at the overlapping position of the large protective sheet and the small protective patch.

[0011] A further improvement to the above solution is that the inner protective material layer and the outer protective material layer each include two large protective panels, and the inner seam and the outer seam are respectively sewn at the overlapping position of the two large protective panels.

[0012] A further improvement to the above solution is that the outer fabric layer is provided with a decorative strip, which is located at the outer seam.

[0013] A further improvement to the above solution is that the decorative strip is made of non-elastic webbing.

[0014] A medical radiation protective suit, comprising a staggered sewing structure for preventing radiation leakage as described in any of the above embodiments.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a staggered sewing structure that can prevent radiation leakage, including an inner fabric layer, an inner protective material layer, an outer protective material layer, an outer fabric layer, an inner seam, and an outer seam. The inner fabric layer, the inner protective material layer, the outer protective material layer, and the outer fabric layer are arranged sequentially from the inside to the outside. The inner fabric layer and the inner protective material layer are sewn together by the inner seam, and the outer fabric layer and the outer protective material layer are sewn together by the outer seam. The inner seam and the outer seam are staggered.

[0016] Compared to the existing through-hole sewing structure used in medical radiation protective clothing, this invention adopts a staggered sewing structure. The pinholes formed by the inner seam are covered by the outer protective material layer, and the pinholes formed by the outer seam are covered by the inner protective material layer. This ensures that radiation leaking from the pinholes formed by the inner seam is shielded by the outer protective material layer, and radiation leaking from the pinholes formed by the outer seam is shielded by the inner protective material layer, thus effectively preventing radiation leakage into the human body. This invention does not have completely through-hole pinholes, which can prevent radiation leakage and ensure a more reliable overall protective effect. It is better suited for sewing and connecting medical radiation protective clothing. Attached image description:

[0020] Explanation of reference numerals in the attached drawings: Inner fabric layer 1, Inner protective material layer 2, Outer protective material layer 3, Outer fabric layer 4, Inner seam 5, First inner seam segment 51, Second inner seam segment 52, Third inner seam segment 53, First inner needle hole 54, Second inner needle hole 55, Outer seam 6, First outer seam segment 61, Second outer seam segment 62, Third outer seam segment 63, First outer needle hole 64, Second outer needle hole 65, Large protective piece 7, Small protective patch 8, Large protective section 9, Decorative strip 10. Detailed implementation method:

[0021] Example 1, as Figure 1-3 As shown, the present invention discloses a staggered sewing structure for preventing radiation leakage, comprising an inner fabric layer 1, an inner protective material layer 2, an outer protective material layer 3, an outer fabric layer 4, an inner seam 5, and an outer seam 6. The inner fabric layer 1, inner protective material layer 2, outer protective material layer 3, and outer fabric layer 4 are arranged sequentially from the inside out. The inner fabric layer 1 and the inner protective material layer 2 are sewn together by the inner seam 5, and the outer fabric layer 4 and the outer protective material layer 3 are sewn together by the outer seam 6. The inner seam 5 and the outer seam 6 are staggered. Compared to the existing fully through-hole sewing structure used in medical radiation protective clothing, this invention... The new design employs a staggered sewing structure. The pinhole formed by the inner seam 5 is covered by the outer protective material layer 3, and the pinhole formed by the outer seam 6 is covered by the inner protective material layer 2. This ensures that radiation leaking from the pinhole formed by the inner seam 5 is shielded by the outer protective material layer 3, and radiation leaking from the pinhole formed by the outer seam 6 is shielded by the inner protective material layer 2, thus effectively preventing radiation leakage. This design does not have any completely penetrating pinholes, preventing radiation leakage and ensuring a more reliable overall protective effect. It is better suited for sewing and connecting medical radiation protective clothing.

[0022] The inner seam 5 includes a first inner seam segment 51, a second inner seam segment 52, and a third inner seam segment 53. The first inner seam segment 51 passes through the inner fabric layer 1 and the inner protective material layer 2 from the inside out, forming a first inner needle hole 54. The third inner seam segment 53 passes through the inner protective material layer 2 and the inner fabric layer 1 from the outside in, forming a second inner needle hole 55. The second inner seam segment 52 is located outside the inner protective material layer 2 and between the first inner seam segment 51 and the third inner seam segment 53. The outer seam 6 includes a first outer seam segment 61 and a second outer seam segment 63. 2. The third outer line segment 63, the first outer line segment 61 passes through the outer fabric layer 4 and the outer protective material layer 3 from the outside to the inside and forms the first outer pinhole 64, the third outer line segment 63 passes through the outer protective material layer 3 and the outer fabric layer 4 from the inside to the outside and forms the second outer pinhole 65, the second outer line segment 62 is located inside the outer protective material layer 3 and between the first outer line segment 61 and the third outer line segment 63; the first inner pinhole 54, the second inner pinhole 55, the first outer pinhole 64 and the second outer pinhole 65 are all staggered.

[0023] There are at least two inner seams 5 and two outer seams 6. Since the inner protective material layer 2 and the outer protective material layer 3 are relatively heavy, with a protective weight of 5-10 kg, by setting multiple inner seams 5 and outer seams 6, the weight can be distributed among the inner seams 5 and outer seams 6, avoiding stress concentration, thereby better ensuring the overall service life.

[0024] Both the inner protective material layer 2 and the outer protective material layer 3 include at least two protective sheets. The protective sheets of the inner protective material layer 2 are arranged sequentially from the inside to the outside, and the protective sheets of the outer protective material layer 3 are arranged sequentially from the inside to the outside. The lead equivalent of the protective sheets is at least 0.125 mmPb, which can better ensure effective blocking and protection against radiation.

[0025] Because individuals vary in height and size, the sizes of the products they wear vary considerably. The protective materials are generally produced in widths of 1.2 meters and 1.25 meters. The choice between a one-piece or three-piece medical radiation protective suit depends on the specific circumstances.

[0026] When the medical radiation protective suit is a single piece, compared to the inner protective material layer 2 and outer protective material layer 3 of this utility model, which each consist of two large protective pieces 7, not only does it require more material overall, but it is also heavier overall; for example Figure 2 As shown, the inner protective material layer 2 and the outer protective material layer 3 of this utility model respectively include a large protective sheet 7 and a small protective patch 8. The inner seam 5 and the outer seam 6 are respectively sewn at the overlapping position of the large protective sheet 7 and the small protective patch 8. The size of the small protective patch 8 is only enough to cover the pinhole formed by the inner seam 5 and the outer seam 6, which can reduce the overall weight while preventing radiation leakage and ensuring the protective effect.

[0027] When it is a three-piece medical radiation protective suit, such as Figure 3 As shown, the inner protective material layer 2 and the outer protective material layer 3 of this utility model each include two large protective panels 9. The inner seam 5 and the outer seam 6 are respectively sewn at the overlapping position of the two large protective panels 9, which can realize the splicing of multiple protective materials while preventing radiation leakage and ensuring the protective effect. In addition, compared with the existing three-piece medical radiation protective clothing with eight layers at the overlapping seam, the three-piece medical radiation protective clothing of this utility model has only six layers at the overlapping seam, which reduces the thickness of the sewn area and increases the comfort and softness of the protective clothing.

[0028] The outer fabric layer 4 is provided with a decorative strip 10, which is located at the outer seam 6. By setting the decorative strip 10 at the outer seam 6, the outer seam 6 can be made less conspicuous, thus playing a decorative role and making the overall appearance more beautiful.

[0029] Since both the fabric and protective materials have a certain degree of elasticity, the decorative strip 10 of this utility model is made of non-elastic webbing, which strengthens the vertical rigidity of the protective clothing, reduces and eliminates the tearing of the protective materials at the armpits and shoulders due to gravity, and extends the service life of the protective clothing.

[0030] Example 2: A medical radiation protective suit, including the staggered sewing structure described in Example 1 that can prevent radiation leakage, thus ensuring a more effective overall protection.

[0031] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
