Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and more particularly to medical screens, especially a roll-up bed surround screen. Background Technology

[0002] In hospital wards, using screens around beds is a common practice to protect patient privacy and reduce external interference and cross-infection. Currently, the most common type is the ordinary sheet screen, which is usually composed of a single large-area screen panel of rigid or flexible material and a supporting frame.

[0003] However, this traditional sheet-like screen has obvious drawbacks in practical applications:

[0004] 1. Inconvenient storage and movement: Due to its inherent sheet-like structure, it is large and rigid, requiring a significant amount of vertical or horizontal space for storage, which is extremely inconvenient in the already crowded ward environment. Furthermore, its large size makes it difficult to move and transport.

[0005] 2. Limited privacy: Single-panel screens can usually only be arranged in simple straight lines or L-shapes, making it difficult to tightly and closely surround the hospital bed to form a complete private space. Large gaps are likely to exist between the screen and the hospital bed, and between the screen and the floor, failing to achieve comprehensive privacy protection. Utility Model Content

[0024] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0025] like Figures 1 to 6 As shown, this embodiment provides a roll-up hospital bed surround screen, including a main rod 1 and several secondary rods 3, which are four secondary rods 3 in this embodiment.

[0026] The main pole 1 includes a first pole body 101 and a flexible screen 2. The first pole body 101 adopts a hollow circular tube structure. The bottom of the first pole body is connected to the base 102 via a telescopic rod 105. The telescopic rod 105 is preferably a sleeve structure, consisting of an inner tube and an outer tube sleeved together, and its height is adjusted and fixed by a locking screw 106 installed radially on the outer tube.

[0027] A base 102 is fixedly installed at the bottom of the telescopic rod 105. Preferably, at least three universal casters 7 with braking function are installed under the base 102 to facilitate movement and positioning. The top of the base 102 is reinforced to the side wall of the first rod body 101 by four reinforcing ribs 104 distributed circumferentially, making the connection more secure.

[0028] A winding device is installed inside the first rod 101. This winding device is a purely mechanical spring-loaded roller blind mechanism, its core function being to achieve automatic winding using the elastic potential energy of a spring. The device includes a bracket fixed inside the first rod 101, a roller mounted on the bracket via bearings, and a spiral spring (i.e., a spring-loaded coil) coiled inside the roller. The inner end of the spring-loaded coil is fixed to the roller, and the outer end is fixed to the bracket. The inner end of the screen 2 is fixedly connected to the roller. When the screen 2 is pulled outwards, the roller rotates, forcing the spring-loaded coil to tighten and store energy; when the screen 2 is released, the spring-loaded coil releases its energy, driving the roller to rotate in the opposite direction, thereby automatically and smoothly winding the screen 2 back onto the roller.

[0029] On the side wall of the first rod 101, a first through groove 111 is vertically opened along its axis. The first through groove 111 is slightly larger than the height of the screen 2 to ensure that the screen 2 can freely enter and exit the first through groove 111.

[0030] One end of the screen 2 passes through the first through slot 111, extends into the first rod body 101, and is fixedly connected to the roll of the winding device. The other end of the screen 2, the free end, has an end strip 4 fixedly installed along its length. This end strip 4 is a rigid long strip with two retaining rings 5. One side of each retaining ring 5 is rotatably connected to the end strip 4 via a flexible connecting band, allowing the retaining ring 5 to rotate relative to the end strip 4 in a vertical plane.

[0031] The auxiliary rod 3 includes a second rod body 301, which is a solid structure to provide sufficient counterweight and stability. A second through groove 302 is vertically formed on the side wall of the second rod body 301. The length of the second through groove 302 is greater than the height of the screen 2 to ensure that the screen 2 can pass through smoothly. Along the length of the second through groove 302, there are slots 303 corresponding to the number and position of the retaining rings 5 ​​on the end bar 4. These slots 303 are arranged laterally, that is, their length direction is perpendicular to the second through groove 302.

[0032] Each auxiliary rod 3 has a fastening device 6 at its bottom, which is specifically a C-clamp. This C-clamp mainly consists of a C-shaped frame and a fastening screw. The upper end of the C-shaped frame is fixedly connected to the bottom of the second rod 301, and its opening is used to clamp into the bed rail of the hospital bed 8 from the side. The fastening screw is screwed horizontally into a threaded hole on one side arm of the C-shaped frame. One end of the screw inside the C-clamp has an anti-slip pressure block, and the other end has a handwheel that is easy to rotate by hand. When the handwheel is rotated to tighten the screw, the anti-slip pressure block is pressed against the other side of the bed rail, and the screw generates a clamping force to firmly lock the auxiliary rod 3 onto the bed rail.

[0033] Around the central axis of the main rod 1, there are locking devices corresponding to the number of secondary rods 3. In this embodiment, four locking devices are provided and evenly distributed around the main rod 1. Each locking device includes at least two vertically distributed clamps 103. The inner contour of these clamps 103 matches the outer contour of the second rod body 301 of the secondary rod 3, so that the secondary rod 3 can be stably inserted and locked in the clamps 103 when stored, realizing a detachable connection with the main rod 1.

[0034] Specific operating instructions:

[0035] This embodiment is suitable for temporary privacy protection during short-term nursing procedures. The user first moves the main rod 1 to the side of the bed 8, then removes the four auxiliary rods 3 from the locking device of the main rod 1, and securely clamps them to the bed rails of the bed 8 using the C-shaped clips at their bottoms. Next, by loosening the locking screw 106, the first rod body 101 can be pulled up and down to adjust the height of the entire main rod 1 and the screen 2 pulled out from within it. After adjusting to the ideal alignment with the second through slot 302 on the auxiliary rod 3, tightening the locking screw 106 completes the fixation. This structure ensures that the screen 2 remains smoothly connected to the second through slot 302 on each auxiliary rod 3 when unfolded. The screen 2 is pulled out from the main rod 1, passing through the second through slot 302 on each auxiliary rod 3 in sequence. Finally, the retaining ring 5 on the end strip 4 is passed through the second through slot 302 of the last auxiliary rod 3, and then rotated 90 degrees to engage in the transverse retaining groove 303 for fixation, thus forming a complete surrounding private space. When storing, simply reverse the operation; the rewinding device will automatically rewind the screen 2 back into the main rod 1 via a spring.
