Description

Hospital bed brake position indicating device

An indicator device, especially an indicator light device used on a hospital bed.

Traditional hospital beds often include mechanisms to adjust the wheels. These mechanisms typically use manual controls, such as levers or knobs, to allow the user to switch between different wheel states, such as free, oriented, and locked. However, these traditional mechanisms do not provide a clear, visual indication of wheel status. As a result, medical personnel may need to physically check the wheel's position to determine its current status, which can be time-consuming and potentially lead to errors.

Finally, traditional hospital beds typically do not include indicator lights 140 for wheel status. As a result, medical personnel may not be able to easily determine the current condition of the wheel in low light conditions. This lack of visibility can lead to errors and potentially compromise patient safety.

To sum up, solving the above problems is worthy of consideration by those with ordinary knowledge in this field.

In view of the above problems, this invention provides a hospital bed brake position indicating device, which is installed on the hospital bed and can indicate the hospital bed wheel position through light signals, allowing medical staff to quickly confirm the status of the hospital bed.

Please refer to Figure 1A and Figure 1B. 1A and 1B are schematic diagrams of a hospital bed braking position indicating device. The hospital bed brake position indicating device 100 is installed on the hospital bed. The hospital bed brake position indicating device 100 includes a gear lever 110, a gear switch 120, a controller 130 and an indicator light 140.

The gear control lever 110 is installed on the hospital bed, specifically located under the end of the hospital bed, and is designed to be adjusted manually or by foot, allowing the user to change the state of the hospital bed wheels. The position of the gear lever 110 corresponds to the state of the wheels.

The gear lever 110 is designed to be pulled up and down. Through the mechanical structure, the gear lever 110 can control the state of the wheels. The wheel states include free state, directional state and locked state. In the free state, the wheels can rotate freely, which helps to rotate the hospital bed. In the oriented state, the direction of the wheels is fixed but can still rotate, making it suitable for moving hospital beds. In the locked state, the wheels cannot rotate or rotate, which is suitable for situations where the position of the hospital bed needs to be fixed, such as when placing the hospital bed in a ward or checkpoint.

The indicator light 140 has different flashing patterns corresponding to these two states. For example, the free state might be represented by a flashing light, and the locked state might be represented by a green light. In this way, the gear lever 110 not only physically controls the status of the wheel, but also communicates this status to the controller 130, which then notifies the indicator light 140 to display the corresponding light mode.

The gear switch 120 is mounted on the gear lever 110 and is designed to detect the position of the lever and provide position information. The position information corresponds to the position of the wheel. The gear switch 120 may be any switch type suitable for detecting the position of a control lever, such as a reed switch, a rotary switch, or a linear switch.

Please refer to FIGS. 3A and 3B , which illustrate a gear switch 120 according to an embodiment. 3A and 3B are side views and partial components of the gear lever 110 . In this embodiment, the gear switch 120 includes a plurality of sensing switches 122 and sensing elements 121 . The sensing switch 122 is, for example, a linear switch, the sensing element 121 is, for example, a touch element, and the sensing element 121 is provided on the gear lever 110 . In this embodiment, the sensing switch 122 is disposed around the moving path of the gear lever 110 , and the sensing switch 122 is a fixed component disposed on the hospital bed 10 . When the gear lever 110 is pulled, the sensing element 121 will also move accordingly and interact with the sensing switch 122. The sensing switch 122 is triggered by the sensing element 121, and the triggered sensing switch 122 will The stall information will be sent out.

For example, in Figures 3A and 3B, when the gear lever 110 is pulled down to the locked state position, the sensing element 121 will be pushed to the position of the sensing switch 122 (as shown in Figure 3B). Let the sensing switch 122 corresponding to the orientation state be triggered, and let the gear switch 120 send out the corresponding gear information. The controller 130 can receive the gear information and send corresponding light control signals to control the indicator light 140 so that the indicator light 140 flashes in a flashing pattern corresponding to the locked state.

Please refer to FIG. 2 , which shows an architecture diagram of the controller 130 . The controller 130 is electrically connected to the gear switch 120 and the indicator light 140 . The controller 130 is installed on the hospital bed, and the controller 130 may be a programmable logic controller 130 (PLC). The controller 130 receives gear information from the sensing switch 122 . The controller 130 controls the operation of the indicator light 140 based on the gear information, that is, it sends a corresponding light control signal to the indicator light 140 so that the indicator light 140 emits a corresponding light signal.

In addition, the controller 130 not only receives position information from the sensing switch 122 and controls the indicator light 140, but also serves as the main controller 130 of the bed itself. It can control other functions of the hospital bed, such as the lifting and lowering of the bed or the lifting of the upper and lower bed boards.

The indicator light 140 is installed on the hospital bed. Specifically, the indicator light 140 is located at the end of the hospital bed, which is the direction of the patient's feet when lying down. This position can be convenient for medical staff to observe. The indicator light 140 is adapted to receive a light control signal from the controller 130 and change its flashing mode according to the light control signal. The flashing pattern of the indicator light 140 corresponds to the status of the wheel. The indicator light 140 can be any light-emitting element suitable for receiving a light control signal and changing its flashing pattern, such as an LED light.

In practical applications, when the medical staff adjusts the gear lever 110 to control the wheel status, the gear switch 120 can provide gear information according to the gear lever 110, and the controller 130 provides the indicator light 140 with the position information. The indicator light 140 further changes its flashing pattern according to the light control signal to provide a visual indication of the position of the hospital bed wheels. Medical staff can identify the visual indication of the light signal. Identifying the status of the wheels, for example, can quickly identify hospital beds that are not correctly fixed in the ward to avoid possible dangers and add better functionality and safety to the hospital bed.

The scope of patent protection shall depend on the appended patent application scope and its equivalent fields. Any changes or modifications made by those with ordinary knowledge in the art without departing from the spirit or scope of this patent shall be equivalent changes or designs completed within the spirit disclosed in this invention, and shall be included in the following patent application scope. within.
