Description

Technical Field

[0001] This utility model belongs to the field of radiation protection technology, specifically relating to a lead apron auxiliary weight reduction device. Background Technology

[0002] Lead aprons are a special type of clothing that can shield against radiation, minimizing harm to the user. Therefore, lead aprons are an indispensable and optimal radiation protection tool. However, lead aprons are quite heavy, and wearing them for extended periods can seriously affect the health of those who wear them for long periods. Furthermore, currently used personal protective equipment in clinical settings is primarily heavy-duty lead-containing suits. Medical staff spend most of their day standing and bearing this weight while repeatedly performing interventional procedures, which over time leads to occupational neck and back pain.

[0003] To address the aforementioned technical problems, existing technologies disclose methods for reducing the load on lead aprons by using exoskeleton support devices to alleviate the burden on medical personnel (such as the related patent technology disclosed in publication number CN118752468A). These exoskeleton support devices transfer the load of the lead apron to the ground via foot pedals supported on the ground. This structure only provides load reduction when the wearer is standing still. When the wearer walks or moves, there is a leg lifting action, which lifts one foot and the foot pedal on the sole of that foot, causing the foot pedal to detach from the ground. This prevents the corresponding load of the lead apron from being transferred to the ground. Since the exoskeleton also has a certain weight, when this leg is lifted, the wearer needs to provide more force to bear part of the weight of the exoskeleton support device, thus increasing the burden on the wearer when walking or moving.

[0032] The following is combined Figures 1-6 This utility model will be described in detail.

[0033] A lead apron-assisted weight reduction device, in some embodiments, such as Figures 1-6 As shown, it includes:

[0034] A back support assembly for supporting the back and shoulders of the lead apron;

[0035] A lumbar support assembly, which is connected to the bottom of the back support assembly and used to support the waist of the lead apron;

[0036] Two sets of leg support components, each set of the leg support components is rotatably connected to the waist support components, and the bottom of the leg support components is supported on the ground by foot fixing components;

[0037] The foot fixing assembly includes a support side plate 1 rotatably connected to the leg support assembly, a support base plate 2 connected to the inner side of the support side plate 1, a wearing fixing sleeve 3 provided on the support base plate 2, and a walking assistance assembly provided on the outer side of the support side plate 1.

[0038] In practical use, medical staff wear this invention on their body and then put on a lead apron over it. The back support component lifts the back and shoulders of the lead apron, so that the load of the entire lead apron is transferred to the ground from the shoulders through the back support component, waist support component, leg support component, and foot fixing component. The walking assistance mechanism shares part of the load of the lead apron, and when medical staff walk, this invention always maintains contact with the ground through the walking assistance mechanism, so that the load shared by the walking mechanism can still be transferred to the ground. Therefore, the wearer does not need to provide more force to bear part of the weight of the exoskeleton support device, thereby reducing the burden on the wearer when walking.

[0039] In some embodiments, such as Figures 1-6 As shown, the walking assistance component includes a mounting sleeve 4 connected to the support side plate 1. The opening of the mounting sleeve 4 is vertically downward and a support column 5 is slidably connected inside the mounting sleeve 4. A roller 6 is rotatably connected to the bottom of the support column 5. A first compression spring is provided between the top end of the mounting sleeve 4 and the top end of the support column 5.

[0040] When medical personnel are standing, the first compression spring is in a compressed state, and its rebound force will bear part of the weight of the lead apron, reducing the burden on the support side plate 1. When medical personnel walk, one foot is raised to a certain height. At this time, the support column 5 slides downward relative to the mounting sleeve 4 under the action of the first compression spring, so that the roller 6 at the bottom of the support column 5 always keeps in contact with the ground. When the foot is raised and steps forward, the roller 6 rolls on the ground, reducing movement friction. It is worth mentioning that the sliding distance of the support column 5 in the mounting sleeve 4 is set in the height range of 15cm to 30cm to meet the height of the foot raised when walking and to prevent the roller 6 from detaching from the ground when the medical personnel raise their feet.

[0041] In some embodiments, such as Figure 6 As shown, the walking assistance component also includes a mounting plate 7 fixedly connected to the inner side of the support base plate 2, and the mounting sleeve 4 is also installed on the outer side of the mounting plate 7.

[0044] In practical use, the mounting sleeve 4 is rotatably connected to the support side plate 1 or the mounting plate 7, which can prevent the mounting sleeve 4 from being not perpendicular to the ground due to the movement of the ankle when the wearer walks, thereby affecting the stability of the support column 5.

[0045] In some embodiments, such as Figures 1-6 As shown, there are two rollers 6 at the bottom of the support column 5, which are arranged sequentially along the length of the support base plate 2.

[0046] In practical use, the contact area between the walking assistance mechanism and the ground is increased, thereby increasing the stability of the device when medical personnel walk.

[0047] In some embodiments, such as Figures 1-6 As shown, the back support assembly includes a support plate 9 rotatably connected to each other. A first fixing strap 10 is provided on the front side of the support plate 9. A sliding plate 11 is slidably connected to the top of the support plate 9. The top of the sliding plate 11 extends out from the top of the support plate 9 and bends towards the front of the support plate 9. A shoulder support plate 12 is rotatably connected to the outside of the sliding plate 11. A second torsion spring is provided between the sliding plate 11 and the shoulder support plate 12.

[0048] In practical use, the shoulder support plate 12 supports the shoulders of the lead apron, the support back plate 9 supports the back of the lead apron, and the shoulder support plate 12 is rotatably connected to the sliding plate 11 to accommodate the movement of the medical staff's shoulder joint.

The top of the arc-shaped support plate 15 is fixedly connected to the support back plate 9 via an elastic mounting plate 16. A second fixing strap 17 is provided on the front side of the arc-shaped support plate 15.

[0052] In practical use, the arc-shaped support plate 15 supports the waist and hip area of ​​the lead apron, and the second fixing strap 17 is used to fix the device when worn.

[0053] In some embodiments, such as Figures 1-6 As shown, the leg support assembly includes a first support sleeve 18 rotatably connected to the end of the arc-shaped support plate 15. The first support sleeve 18 has an opening facing downwards and a first support rod 19 is slidably connected inside the first support sleeve 18. A second support sleeve 20 is rotatably connected to the bottom end of the first support rod 19. A second support rod 21 is slidably connected to the bottom end of the second support sleeve 20, which has an opening facing downwards. The bottom end of the second support rod 21 is rotatably connected to the support side plate 1. The rear side of the first support sleeve 18 is rotatably connected to the top of the assist sleeve 23 via a triangular support plate 22. An assist support rod 24 is slidably connected inside the assist sleeve 23. The bottom end of the assist support rod 24 is rotatably connected to the rear side of the second support sleeve 20. A second compression spring is provided between the top end of the assist sleeve 23 and the top end of the assist support rod 24.

[0054] In practical use, the first support sleeve 18 and the first support rod 19 support the thigh part of the lead apron, the second support sleeve 20 and the second support rod 21 support the lower leg part of the lead apron; the assist sleeve 23 and the assist support rod 24 assist the wearer in walking.

[0055] In some other embodiments, such as Figures 1-6 As shown, the inner side of the first support sleeve 18 is provided with a third fixing strap 25, which is used to fix it to the wearer's thigh and improve the stability of the device.

[0056] The specific working principle of this utility model:

[0057] Medical personnel wear this invention on their body and then put on a lead apron over it. The back support component lifts the back and shoulders of the lead apron, so that the load of the entire lead apron is transferred to the ground from the shoulders through the back support component, waist support component, leg support component, and foot fixing component. The walking assistance mechanism shares part of the load of the lead apron, and when medical personnel walk, this invention maintains contact with the ground through the walking assistance mechanism, so that the load shared by the walking mechanism can still be transferred to the ground. Therefore, the wearer does not need to provide more force to bear part of the weight of the exoskeleton support device, thereby reducing the burden on the wearer when walking.

[0058] When medical staff are standing, the first compression spring is in a compressed state, and the rebound force it generates will bear part of the weight of the lead apron, reducing the burden on the support side plate 1. When medical staff walk, one foot is raised to a certain height. At this time, the support column 5 slides downward relative to the mounting sleeve 4 under the action of the first compression spring, so that the roller 6 at the bottom of the support column 5 always keeps in contact with the ground. When the foot is raised and steps forward, the roller 6 rolls on the ground, reducing movement friction.

[0059] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
