Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a radiation-proof facial shield. Background Technology

[0002] According to the radiation protection guidelines for interventional diagnosis and treatment medical personnel, medical personnel involved in radiological diagnosis and treatment are required to use various radiation protection products, including lead aprons and lead masks, depending on the type of operation. Radiation-proof lead glass is often used in radiation protection projects due to its high lead content (≥26%) and light transmittance (≥95%). Therefore, using radiation-proof lead glass to make radiation-proof masks can protect medical personnel while providing them with a good field of vision.

[0003] Lead aprons and lead masks need to be worn continuously during treatment, which places a continuous and additional physical strain on medical staff. Therefore, lead aprons are currently used in conjunction with exoskeletons. Specifically, the lead apron has an opening on the front. To use it, the opening is first opened to the sides, then the lead apron is connected to the exoskeleton and placed upright on the ground. The medical staff then inserts their torso into the lead apron through the gap between the openings in front of the exoskeleton. However, because the mask is located in front of the lead apron, the mask, which is integrated with the exoskeleton and level with the medical staff's head, can obstruct the medical staff's movement when they retract into the lead apron, and there is a risk of head injury when inserting the head between the mask and the lead apron.

[0004] Therefore, a protective device that can be connected to the shoulder component of an exoskeleton is designed, specifically a radiation-proof face shield. Utility Model Content

[0005] To overcome the problems mentioned in the background art, the present invention adopts the following technical solution:

[0006] A radiation-proof face shield includes: a glass lead screen having a first curved surface and a second curved surface, the first curved surface being concave inward and the second curved surface being convex outward, the distance between the first and second curved surfaces being the thickness of the glass lead screen; a first connecting structure fixedly connected to the glass lead screen, the two first connecting structures being mirror-symmetrical about the sagittal plane of the glass lead screen; and a second connecting structure including a connecting plate and a connecting rod, the connecting plate being rotatably connected to the first connecting structure, the connecting rod being provided with at least two grippers, a clamping channel being provided between the grippers, and when the connecting rod moves along the shoulder assembly of an exoskeleton and connects the clamping channel with the exoskeleton, the relative positional relationship between the second connecting structure and the exoskeleton can be locked. When the relative positional relationship between the second connecting structure and the exoskeleton is locked, the load exerted on the user by the glass lead screen is distributed by the exoskeleton, thereby reducing the user's physical exertion.

[0007] Furthermore, the grippers are provided with openings, and the two grippers are aligned axially with the connecting rod. The clamping channel extends axially along the connecting rod and allows the insertion of rod-shaped components of the exoskeleton. The connecting rod is elastic, and when the clamping channel is fitted with exoskeleton components of different shapes, the portion of the connecting rod between adjacent grippers undergoes elastic deformation. Because the connecting rod is elastic, when the second connecting structure is adapted to different types of exoskeletons, the shape of the connecting rod can be adjusted to allow the clamping channel to fit rod-shaped shoulder components of different exoskeletons.

[0008] Furthermore, the first connecting structure includes connecting bolts. A first side edge and a second side edge are located between the first curved surface and the second curved surface. The connecting bolts are inserted into the glass lead screen through the first side edge and the second side edge, respectively. The connecting bolts are fixedly connected to the glass lead screen, and there are at least two connecting bolts. The plurality of connecting bolts in the first connecting mechanism can share the stress at the connection point between the connecting bolts and the glass lead screen when the glass lead screen moves.

[0009] Furthermore, the first connection structure also includes an adapter, which is connected to a connecting bolt. The adapter is rotatably connected to the connecting plate on the same axis, and the glass lead screen rotates when the adapter rotates around the axis.

[0010] Furthermore, the connecting plate has a limiting end, which is disposed on the extension path of the clamping channel. When the shoulder assembly of the exoskeleton enters the clamping channel and abuts against the limiting end, the limiting end restricts the shoulder assembly of the exoskeleton from moving along the clamping channel toward the glass lead screen.

[0011] Furthermore, the connecting plate is provided with a threaded hole that communicates with the clamping channel. A limit pin is bolted into the threaded hole. When the limit pin enters the clamping channel along the axial direction of the threaded hole and presses the shoulder assembly of the exoskeleton, it locks the relative positional relationship between the second connecting structure and the exoskeleton.

[0012] Furthermore, a knob is provided at the end of the limiting pin that is away from the screw hole. When the exoskeleton is inserted into the clamping channel, rotating the knob will cause the limiting pin to move into the clamping channel to press the exoskeleton.

[0013] Furthermore, the limiting pin is perpendicular to the connecting rod.

[0014] Furthermore, the first curved surface faces the first connecting structure to provide space for the user's head, while the second curved surface faces away from the first connecting structure.

[0015] Furthermore, the curvature of the upper edge of the first curved surface is π, and the curvature of the lower edge of the first curved surface is also π; the curvature of the upper edge of the second curved surface is the same as that of the upper edge of the first curved surface, and the curvature of the lower edge of the second curved surface is the same as that of the lower edge of the first curved surface. Since the first side edge and the second side edge are flush, the face mask provides the user with a 180° protective field of vision.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model features a connecting plate with grippers and limiting pins, allowing it to connect to the exoskeleton after the user has donned the lead apron fitted with it. This eliminates the need for the user to cover their head, thus eliminating the risk of head injury from the glass lead screen during the wearing process. Furthermore, without compromising wearability, the exoskeleton helps reduce the additional physical exertion caused by the glass lead screen.

[0018] 2. By setting up adapters and connecting plates, the relative positional relationship between the glass lead screen and the second connecting structure can be adjusted, which is beneficial for adjusting the distance and angle between the glass lead screen and the user's face.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] A type of radiation-proof face shield, such as Figure 1-8As shown, it includes: a radiation-proof face shield, comprising: a glass lead screen 1, having a first curved surface 11 and a second curved surface 12, the first curved surface 11 being a concave surface and the second curved surface 12 being a convex surface, the distance between the first curved surface 11 and the second curved surface 12 being the thickness of the glass lead screen 1; a first connecting structure 2, which is fixedly connected to the glass lead screen 1, the two first connecting structures 2 being mirror-symmetrical about the sagittal plane of the glass lead screen 1; a second connecting structure 3, including a connecting plate 31 and a connecting rod 32, the connecting plate 31 being rotatably connected to the first connecting structure 2, the connecting rod 32 being provided with at least two grippers 33, a clamping channel 331 being provided through the grippers 33, when the connecting rod 32 moves along the shoulder assembly 4 of the exoskeleton and connects the clamping channel 331 with the exoskeleton, the relative positional relationship between the second connecting structure 3 and the exoskeleton can be locked. When the relative position of the second connecting structure 3 and the exoskeleton is locked, the load exerted on the user by the glass lead screen 1 is distributed by the exoskeleton, thereby reducing the user's physical exertion. One of the claws 33 on each connecting rod 32 is away from the first connecting structure 2, and the rod-shaped shoulder assembly of the exoskeleton is inserted into the clamping channel 331 from the claw 33. Two or more claws 33 ensure the relative position of each connecting rod 32 with the rod-shaped shoulder assembly on one side, while the connection between the second connecting structures 3 on both sides and the rod-shaped shoulder assembly respectively maintains the stability of the connection between the face mask and the exoskeleton. The opening 7 is located on the front side of the lead apron. After the face mask is connected to the exoskeleton, it is above the two openings 7 and level with the user's head. One end of the opening 7 is connected to the collar of the lead apron, and the other end of the opening 7 is connected to the lower opening of the lead apron. When the opening 7 is open to both sides, it provides a passage for medical personnel to enter the interior of the lead apron. The outer sides of the two openings 7 are usually provided with Velcro, so that the openings 7 have partial overlap when connected, which can prevent radiation from passing through the lead apron through the connection point of the openings 7.

[0031] In some embodiments of this application, such as Figure 1-8As shown, the grippers 33 have openings, and the two grippers 33 are aligned axially with the connecting rod 32. The clamping channel 331 extends axially along the connecting rod 32 and allows the insertion of rod-shaped components of the exoskeleton. The connecting rod 32 is elastic; when the clamping channel 331 is fitted with exoskeleton components of different shapes, the portion of the connecting rod 32 between adjacent grippers 33 undergoes elastic deformation. Because the connecting rod 32 is elastic, when the second connecting structure 3 is adapted to different types of exoskeletons, the shape of the connecting rod 32 can be adjusted so that the clamping channel 331 can fit the rod-shaped shoulder components of different exoskeletons. Because the connecting rod 32 is elastic, it tends to return to its initial state when the clamping channel 331 is fitted with the exoskeleton, thus applying frictional resistance to the fitted portion of the exoskeleton and improving the stability of the connection. The exoskeleton's rod-shaped shoulder assembly is elastic. This invention, which assists users in reducing the burden of wearing lead aprons and masks, also includes the following components: a leg support assembly 6 that contacts the ground and connects to the user's legs; and a back-lumbar connection assembly 5 located on the user's lower back and connected to the leg support assembly 6. In use, the shoulder assembly connects to the user's lead apron and tends to lift it away from the user's shoulders. Simultaneously, the shoulder assembly connects to the back-lumbar connection assembly 5, which supports both the shoulder assembly and the back-lumbar connection assembly 5 by connecting to the leg support assembly 6. Thus, while the shoulder assembly lifts the lead apron, the pressure of the lead apron on the shoulder assembly is transferred to the leg support assembly 6 via the back-lumbar connection assembly 5. The leg support assembly 6, in turn, contacts the ground, allowing the weight of the lead apron to be guided to the ground sequentially through the shoulder assembly 4, back-lumbar connection assembly 5, and leg support assembly 6 of the exoskeleton, forming a stable support system. Therefore, by connecting the face mask of this invention to the shoulder component 4 of the exoskeleton, the burden of the face mask's weight on the user's movements during diagnostic or treatment procedures is also shared by the exoskeleton in the aforementioned manner. Simultaneously, the detachable design of the face mask and shoulder component effectively solves the problem of the face mask obstructing the user's movement during wear.

[0032] In some embodiments of this application, such as Figure 1-8 As shown, the first connecting structure 2 includes a connecting bolt 21, and an adapter 22 connected to the connecting bolt 21. The adapter 22 includes a block structure and a plate structure, which are integrally connected. The block structure is fixedly connected to the connecting bolt 21, and the plate structure is provided with a shaft hole and rotatably connected to a connecting plate 31 provided with a rotating shaft. A first side edge 13 and a second side edge 14 are provided between the first curved surface 11 and the second curved surface 12. The connecting bolt 21 is inserted into the glass lead screen 1 through the first side edge 13 and the second side edge 14 respectively. The connecting bolt 21 is fixedly connected to the glass lead screen 1, and there are at least two connecting bolts. The plurality of connecting bolts 21 provided in the first connecting mechanism can share the stress at the connection between the connecting bolt 21 and the glass lead screen 1 when the glass lead screen 1 moves.

[0033] In some embodiments of this application, such as Figure 1-8 As shown, the first connecting structure 2 also includes an adapter 22, which is rotatably connected to the connecting plate 31 on the same axis. When the adapter 22 rotates around the axis, it drives the glass lead screen 1 to rotate.

[0034] In some embodiments of this application, such as Figure 1-8 As shown, the connecting plate 31 has a limiting end 311, which is disposed on the extension path of the clamping channel 331. When the shoulder assembly 4 of the exoskeleton enters the clamping channel 331 and abuts against the limiting end 311, the limiting end 311 restricts the shoulder assembly 4 of the exoskeleton from moving along the clamping channel 331 toward the glass lead screen 1.

[0035] In some embodiments of this application, such as Figure 1-8 As shown, the connecting plate 31 is provided with a screw hole 321, which is connected to the clamping channel 331. A limit pin 322 is bolted into the screw hole 321. When the limit pin 322 enters the clamping channel 331 along the screw hole 321 and presses the shoulder component 4 of the exoskeleton, it locks the relative positional relationship between the second connecting structure 3 and the exoskeleton.

[0036] In some embodiments of this application, such as Figure 1-8 As shown, a knob 323 is provided at the end of the limiting pin 322 that is away from the screw hole 321. When the exoskeleton is inserted into the clamping channel 331, rotating the knob 323 causes the limiting pin 322 to move into the clamping channel 331, thereby clamping the exoskeleton. The limiting pin 322 is perpendicular to the connecting rod 32, so as to apply positive pressure to the exoskeleton to the maximum extent and convert it into frictional resistance to prevent the exoskeleton from falling out of the clamping channel 331.

[0037] In some embodiments of this application, such as Figure 1-8 As shown, the first curved surface 11 faces the first connecting structure 2, providing space for the user's head, while the second curved surface 12 faces away from the first connecting structure 2.

[0038] In some embodiments of this application, such as Figure 1-8 As shown, the curvature of the upper edge of the first curved surface 11 is π, and the curvature of the lower edge of the first curved surface 11 is also π; the curvature of the upper edge of the second curved surface 12 is the same as that of the upper edge of the first curved surface 11, and the curvature of the lower edge of the second curved surface 12 is the same as that of the lower edge of the first curved surface 11. Since the first side edge 13 and the second side edge 14 are flush, the face mask provides the user with a 180° protective field of vision.
