Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a bedside call device for hospital wards. Background Technology

[0002] To ensure patients receive better care during treatment and to enable medical staff to provide timely and accurate medical services, bedside call devices are now commonly installed in hospital wards for quick access to on-call medical personnel. Current bedside call devices typically consist of a call unit, an extension cable, and a control button. Patients press the control button to make a call. The control button is connected to the call unit via the extension cable. In practice, the control button is usually placed or hung at the head of the bed, and the fixed length of the extension cable cannot be adjusted to suit the patient's needs, frequently resulting in accidental activation. Therefore, a new call device is urgently needed to solve these problems. Utility Model Content

[0003] The present invention aims to provide a bedside call device for hospital wards to solve the problem that existing bedside call devices cannot be adjusted.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The basic technical solution provided by this utility model is as follows: a bedside call device for wards, including a call device body, a wire, a winding assembly, and a call button. The call device body and the call button are electrically connected by a wire. A winding assembly is provided on the wire, which includes a coil frame and a rotating shaft. The rotating shaft passes through the coil frame. After the center of the wire passes through the rotating shaft, its two ends are wound onto the two ends of the rotating shaft. A spring is provided in the cavity between the rotating shaft and the coil frame. A check block and a moving rod are respectively provided inside the coil frame. An anti-accidental contact component is provided at one end of the moving rod, and the other end of the moving rod is connected to a positioning spring. A push block is provided on the moving rod, and the push block contacts the inclined surface of the inclined block. The inclined block is located on the side of the check block. The bottom end of the check block is connected to a compression spring. The top end of the check block passes through the shaft of the coil frame and engages with a ratchet ring. The ratchet ring is located inside the rotating shaft.

[0006] Furthermore, the anti-accidental touch component includes a rotating rod and a torsion spring. The torsion spring is sleeved on the rotating rod, and both the rotating rod and the torsion spring pass through the moving rod. A pressing plate is provided at the end of the rotating rod, and a limit block is provided on the rotating rod. The limit block and the limit groove are misaligned and correspond to each other. The limit groove is opened on the reel frame.

[0007] Furthermore, buffer components are provided at the connection points between the call button and the call device body and the wire. The buffer components include a limiting frame and a collar. Sliding sleeves and buffer springs are fitted on the limiting posts on both sides of the limiting frame. The buffer springs are connected to the top surface of the sliding sleeves. A collar is provided between the two sets of sliding sleeves and is fitted on the wire.

[0008] Furthermore, a protective sleeve is provided on the outside of the buffer assembly.

[0009] The principle and beneficial effects of the basic technical solution are as follows: By rotating the shaft on the wire reel frame, the winding or unwinding of both ends of the wire is achieved, thereby realizing the extension and retraction of the wire. Under the action of the compression spring, the anti-reverse block engages with the ratchet ring on the shaft, so that the shaft can only rotate in one direction. Pulling the wire at the call button end causes the shaft to rotate, releasing the wire. Pushing the moving rod, the push block squeezes the inclined block, causing the anti-reverse block to move downward and separate from the ratchet ring, thereby releasing the one-way locking of the shaft. Under the action of the spring, the shaft rotates back, winding the wire, thus realizing the release and winding of the wire. This allows the length of the device to be adjusted according to the actual use needs of the patient. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0017] like Figures 1-5 The following describes a bedside call device for hospital wards, comprising a call device body 1, a wire 2, a winding assembly, and a call button 3. The call device body 1 and the call button 3 are electrically connected via the wire 2. The wire 2 is equipped with a winding assembly, which includes a coil frame 4 and a rotating shaft 6. The rotating shaft 6 passes through the coil frame 4. After the center of the wire 2 passes through the rotating shaft 6, its two ends are wound onto the two ends of the rotating shaft 6. A spring 5 is installed in the cavity between the rotating shaft 6 and the coil frame 4. One end of the spring 5 is locked inside the rotating shaft 6, and the other end is locked inside the shaft of the coil frame 4. The spring 5 enables the rotating shaft 6 to rotate automatically, quickly winding the wire 2 without the need for manual winding by medical personnel. Anti-reverse blocks 1 are installed inside the coil frame 4. 5. A movable rod 18 is connected to a positioning spring 17. One end of the movable rod 18 is equipped with an anti-accidental contact component, and the other end of the movable rod 18 is connected to the positioning spring 17. The positioning spring 17 presses and positions the movable rod 18 to prevent it from moving arbitrarily. A push block 21 is provided on the movable rod 18. The push block 21 contacts the inclined surface of the inclined block 22. The inclined block 22 is located on the side of the check block 15. The bottom end of the check block 15 is connected to the compression spring 16. The top end of the check block 15 passes through the shaft of the coil frame 4 and engages with the ratchet ring 7. The ratchet ring 7 is located inside the rotating shaft 6. The compression spring 16 keeps the check block 15 pressed against the ratchet ring 7, thereby achieving one-way locking. The push block 21 and the inclined block 22 cooperate to quickly change the state of the check block 15 for easy adjustment.

[0018] The specific implementation process is as follows: When the patient is not using the device or has been discharged, the lead wire 2 is completely retracted onto the rotating shaft 6, and the length of the lead wire 2 is reduced to its shortest length. When the patient uses the device, they only need to hold and pull the call button 3 to pull out the lead wire 2, causing the rotating shaft 6 to rotate and thus release both ends of the lead wire 2 out of the wire reel 4. The lead wire 2 is quickly extended, and at the same time, the spring spring 5 is tightened. After extending the lead wire 2 to the length required by the patient, pulling the lead wire 2 is stopped, and it is released. Under the action of the compression spring 16, the anti-reverse block 15 is always engaged on the ratchet ring 7, which can prevent the rotating shaft 6 from rotating back, thus fixing the length of the lead wire 2. When it is necessary to shorten or retract the lead wire 2, simply press the anti-accidental touch component, which causes the moving rod 18 to move. The push block 21 presses the inclined block 22. Through the inclined surface cooperation between the two, a direction is provided to the anti-reverse block 15. The downward force is greater than the elastic force provided by the compression spring 16, causing the anti-reverse block 15 to move downward and separate from the ratchet ring 7, releasing the one-way lock on the rotating shaft 6. Under the action of the spring spring 5, the rotating shaft 6 automatically rotates, thereby automatically winding the wire 2 onto the rotating shaft 6. When adjusted or stored in place, the anti-accidental touch component is released. Under the action of the positioning spring 17, the moving rod 18 resets, so that the push block 21 no longer presses the inclined block 22, causing it to lose its force on the anti-reverse block 15. The anti-reverse block 15 resets, locking the rotating shaft 6 so that it can only rotate in one direction, facilitating subsequent use. This allows the device to quickly adjust the cable length, enabling it to be adjusted according to the usage needs of different patients. The call button is placed in a position that is easy to access and not easily accidentally touched, replacing the traditional call button with a fixed-length cable, reducing the possibility of accidental touch.

[0019] In this embodiment, the anti-accidental touch component includes a rotating rod 19 and a torsion spring 20. The torsion spring 20 is sleeved on the rotating rod 19, and both the rotating rod 19 and the torsion spring 20 pass through the moving rod 18. A pressing plate 8 is provided at the end of the rotating rod 19, and a limiting block 23 is provided on the rotating rod 19. The limiting block 23 is misaligned with the limiting groove 14, which is opened on the coil frame 4. Under the action of the torsion spring 20, the limiting block 23 is always misaligned with the limiting groove 14. The limiting block 23 is located on the side of the coil frame 4, so that the rotating rod 19 cannot push the moving rod 18 into the coil frame 4, thereby avoiding accidental touch that would cause the rotating shaft 6 to rotate, effectively improving the stability of the device. By rotating and pressing the pressing plate 8, the rotating rod 19 is driven to rotate. When the limiting block 23 is aligned with the limiting groove 14, the rotating rod 19 moves into the coil frame 4 and pushes the moving rod 18 to move, thereby unlocking the device.

[0020] In this embodiment, buffer components are provided at the connection points of the call button 3 and the wire 2, including a limiting frame 9 and a collar 13. Sliding sleeves 10 and buffer springs 11 are fitted on the limiting posts on both sides of the limiting frame 9. The buffer springs 11 are connected to the top surface of the sliding sleeves 10. A collar 13 is provided between the two sets of sliding sleeves 10 and is fitted on the wire 2. When the wire 2 is pulled, the wire 2 is pulled and the collar 13 moves, thereby moving the sliding sleeves 10 on the limiting frame 9 and squeezing the buffer springs 11. The buffer springs 11 provide elastic force to slow down the movement speed of the sliding sleeves 10, thereby reducing the impact of the pulling force on the wire 2 through the collar 13, and preventing the wire 2 from being excessively pulled and damaged.

[0021] In this embodiment, a protective sleeve 12 is provided outside the buffer component; the protective sleeve 12 is made of soft rubber, which covers the buffer component to protect it and also prevents the patient from being pinched by the buffer component, thus improving the safety of the device.

[0022] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
