[0001] This utility model belongs to the field of medical auxiliary equipment technology, and specifically relates to a radiation protection isolation curtain suitable for portable X-ray machines. Background Technology

[0002] During military operations, whether in war or peacetime, injuries are inevitable. Radiologists use portable X-ray machines to image fractures or dislocations, guiding doctors in auxiliary examinations, reductions, or traction fixation. These machines are also used for post-operative follow-ups to assess treatment effectiveness. However, because there are currently no dedicated X-ray shields, other personnel must help by surrounding the portable X-ray machine with lead sheeting to protect other personnel from radiation. This operation requires multiple people, is time-consuming and labor-intensive, and inconvenient to carry, making it particularly unsuitable for wartime or peacetime military operations. Utility Model Content

[0003] To address the above problems, this invention provides a radiation-proof isolation curtain suitable for portable X-ray machines.

Detailed Implementation

[0017] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 As shown in the figure, this utility model provides a radiation-proof isolation curtain suitable for portable X-ray machines, including a lead protective curtain 1 that can be opened and closed. The top of the lead protective curtain 1 can slide and engage with a slide rail 2 located outside the body 00 of the X-ray machine. The tops of the two movable ends of the lead protective curtain 1 are connected to an opening and closing mechanism 100, which is connected to the slide rail 2 and is used to drive the two movable ends of the lead protective curtain 1 to move towards or away from each other to open and close the lead protective curtain 1. The bottom of the slide rail 2 is provided with an umbrella-shaped support frame, and the lead protective curtain 1 can cover the outside of the support frame. In specific applications, the machine body is mounted on a tripod, and the slide rail 2 is connected to the lower part of the machine body 00 through a detachable fixing ring 3. The two movable ends of the lead protective curtain are driven to move towards or away from each other through the opening and closing mechanism to open and close the lead protective curtain. This facilitates the use of the lead protective curtain to cover the patient for X-ray examination, while preventing X-ray exposure and protecting other personnel from ionizing radiation.

[0019] As a preferred structure, such as Figure 3 , Figure 4 As shown, the support frame includes several connecting rods 4 and a circular or elliptical support ring 5 at its lower end. The connecting rods 4 are spaced apart between the slide rail 2 and the support ring 5. The upper end of the connecting rod 4 is connected to the slide rail 2, and the lower end of the connecting rod 4 is connected to the inner side of the support ring 5.

[0020] Further optimize the above structure, such as Figure 9 As shown, a ring of ball bearings 6 is embedded in the outer edge of the support ring 5 to abut against the lead curtain 1, reducing the resistance encountered by the lead curtain during opening and closing. The slide rail 2 and the support frame are both made of fiberglass reinforced plastic, and the ball bearings 6 are made of zirconia ceramic to avoid interference with X-rays. Meanwhile, the connecting rod 4 can be designed as a straight rod or a curved rod with an inward bend, such as... Figure 4 , 7 As shown.

[0021] In specific embodiments of the utility model, such as Figure 5 , Figure 6 As shown, the opening and closing mechanism 100 includes a housing 101 and an internal drive gear 7, driven gear 8, and two measuring tapes 9. The drive gear 7 meshes externally with the driven gear 8 and is connected to a drive element. The axles of the two driven gears 8 are respectively fixedly connected to the rollers 10 of the two measuring tapes 9. One end of each measuring tape 9 is fixed to the roller 10, and the other end passes through the side wall of the housing and is connected to the movable end of the lead protective curtain 1. The measuring tape 9 is an elastic steel sheet and slides with the slide rail 2. In specific manufacturing, a box 102 capable of accommodating the measuring tapes 9 is installed inside the housing 101. The drive gear drives the driven gears on both sides to rotate, realizing the synchronous extension and retraction of the two measuring tapes. During the extension and retraction process, the measuring tapes can move along the length direction of the slide rail, thereby realizing the opening and closing of the lead protective curtain.

[0022] In the specific design, the driving element is a stepper motor (not shown in the figure), and the switch of the motor is located outside the slide rail 2. The stepper motor drives the drive gear to rotate, and the stepper motor can also be remotely controlled.

[0023] In another specific embodiment, such as Figure 5 As shown, the driving element is a crank handle 11, which is eccentrically mounted on a turntable 103 that is coaxially fixed with the drive gear 7. The crank handle can extend above the slide rail for easy operation.

[0024] In specific embodiments of the utility model, such as Figure 7As shown, the slide rail 2 has a C-shaped cross-section, the measuring tape 9 is disposed inside the slide rail 2, and the opening of the slide rail 2 faces outward. The top of the lead protective curtain 1 is slidably engaged with the measuring tape 9 via hanging rings 12. In specific manufacturing, the lead protective curtain 1 is rectangular, and several hanging rings 12 are spaced apart along its length on the top horizontal edge of the lead protective curtain 1. The hanging rings 12 are fitted onto the measuring tape 9. The two movable ends of the lead protective curtain 1 are movably connected. Furthermore, the two movable ends of the lead protective curtain 1 can be connected from top to bottom via Velcro 16.

[0025] The lead protective curtain should be at least 150cm long, 80-100cm away from the limbs, and 150-180cm away from the chest. The specific dimensions of the lead protective curtain can be determined according to specific circumstances. In application, the middle of the lead protective curtain is fixed to the corresponding slide rail on the housing. Driving the drive gear in both directions allows the two movable ends of the lead protective curtain to open and close freely. After closing, it is secured with Velcro to prevent X-ray exposure. When not in use, the Velcro can be opened to retract the lead protective curtain for easy patient evacuation.

[0026] In specific embodiments of the utility model, such as Figure 1 , Figure 8 As shown, the outer side of the machine body 00 is provided with a transparent protective cover 13. The slide rail 2 is located on the lower inner side of the protective cover 13 and in the lower middle part of the machine body 00. The upper end of the protective cover 13 is connected to the machine body 00 via a connector. The connector includes a strap 14 and a connecting strap 15. The middle portions of two opposite edges of the protective cover 13 are respectively connected to the top of the machine body 00 via the strap 14, and the middle portions of the other two edges of the protective cover 13 are respectively connected via the connecting strap 15. The protective cover facilitates the protection of the machine body, and the lower end of the protective cover can cover the slide rail and extend below the slide rail, further preventing X-ray exposure during the inspection process.

[0027] In summary, this invention has the advantages of simple structure, convenient operation, and good protective effect. By installing a slide rail at the bottom of the X-ray machine, the upper middle part of the lead curtain and its opening and closing mechanism are connected to the slide rail. The upper end of the lead curtain is slidably connected to the slide rail via a hanging ring. Rotating the drive gear drives the two movable ends of the lead curtain to move towards or away from each other, thus opening and closing the curtain. Simultaneously, with the help of the umbrella-shaped support frame, the lower part of the lead curtain can be opened after unfolding, facilitating the X-ray examination of the patient. Furthermore, the lead curtain prevents X-ray exposure, protecting other personnel from ionizing radiation. Using this invention, only one person is needed to complete the X-ray examination, resulting in high work efficiency, especially suitable for X-ray examinations in the field or in small spaces.
