Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an anti-accidental touch structure for ward call devices. Background Technology

[0002] Ward call systems are an indispensable piece of equipment in modern hospital wards. They are primarily used by patients to promptly issue a call signal when they need assistance from medical staff, and are typically installed beside the bed for easy access. Call systems come in various forms, including traditional button-operated models and intelligent models with displays and voice functions. When a patient presses the call button, the signal is quickly transmitted to the nurses' station or other designated locations, allowing medical staff to be aware of the patient's call immediately. This not only improves the efficiency of medical staff and ensures patients receive timely assistance, but also enhances patients' sense of security and comfort during their hospital stay.

[0003] Currently, the call buttons in wards lack accidental touch protection. Patients or caregivers may accidentally trigger invalid calls due to unintentional touches (such as turning over, clothing rubbing, or children playing) or equipment vibration. Such accidental touches force medical staff to interrupt their work to go to the ward to confirm, resulting in wasted manpower and response delays. Especially at night or when there is a shortage of medical staff, it may affect the efficiency of handling genuine emergency needs.

[0004] To address this issue, we provide a structure to prevent accidental activation of ward call devices. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-accidental touch structure for ward call systems. By setting the anti-accidental touch component, the problem of existing ward call systems lacking accidental touch protection measures, and the easy impact on the normal work of medical staff when the device is accidentally triggered to sound an alarm, is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model is an anti-accidental touch structure for a ward call button, including a call button, a button housing on one side of the call button, a call button installed on the front side of the button housing, and an anti-accidental touch component on one side of the button housing. The anti-accidental touch component includes a mounting bracket sleeved on the surface of the button housing, a rotating shaft movably connected inside the mounting bracket, and a protective cover installed on the surface of the rotating shaft.

[0008] The present invention is further configured such that the anti-accidental touch component also includes a spring mounted on the surface of the rotating shaft, and the other end of the spring is fixedly connected to the inner wall of the mounting bracket.

[0009] The present invention is further configured such that a connecting plate is fixedly connected to the top of the mounting bracket, a clamping plate is provided on one side of the connecting plate, and a fixing screw is provided on one side of the clamping plate.

[0010] The present invention is further configured such that one end of the fixing screw passes through the clamping plate and is threadedly connected to the connecting plate, and the other end of the fixing screw is fixedly connected to a knob.

[0011] The present invention is further configured such that a wire is installed on one side of the pager button, the other end of the wire is fixedly connected to the pager, and a speaker is installed on the front side of the button housing.

[0012] The present invention is further configured such that a limiting rod is slidably connected inside the connecting plate, and the other end of the limiting rod passes through the connecting plate and is fixedly connected to the clamping plate.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model achieves physical isolation and automatic reset functions through the linkage design of a rotating protective cover and a spring. After the protective cover covers the call button, it can completely block accidental operation (such as turning over, clothing friction, or children touching it), avoiding invalid call triggers. The spring provides elastic energy storage to ensure that the protective cover automatically resets and locks securely after rotation, reducing manual operation steps. This structure is especially suitable for nighttime or scenarios with insufficient medical staff, significantly reducing the number of invalid responses caused by accidental touches, allowing medical staff to focus more on real emergency needs and improving overall nursing efficiency.

[0015] 2. This utility model's mounting bracket, through the cooperation of the clamping plate and the fixing screw, can be flexibly fixed to the surface of the button housing, adapting to call button of different sizes, with strong compatibility. The protective cover is made of transparent PVC material, allowing patients to intuitively check the button status and eliminating psychological barriers. The sliding cooperation between the limiting rod and the connecting plate ensures stable movement of the clamping plate and prevents loosening. When the patient needs to call, they only need to rotate the knob to unlock the protective cover and flip it upwards to operate the button. The process is simple and does not affect normal use. This design ensures the anti-accidental touch function while taking into account the convenience of operation and the user experience of the patient.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-6 This utility model relates to an anti-accidental activation structure for a ward call button, comprising a call button 1, a button housing 2 on one side of the call button 1, and a call button 3 mounted on the front of the button housing 2; the call button 1 and the call button 3 are connected by a wire 12. When a patient presses the call button 3, the metal contacts inside the button close, forming a complete conductive circuit, allowing current to flow through the wire 12. The wire 12, acting as a conductor, transmits this electrical signal from the call button 3 to the call button 1 in the form of voltage or current changes. The call button 1 has a built-in signal processing circuit that processes the received electrical signal. The signal is decoded and analyzed, and then the sound and light alarm device is triggered to issue an alarm to medical staff. This is a mature existing technology application. An anti-accidental touch component is provided on one side of the button shell 2. The anti-accidental touch component includes a mounting bracket 4 sleeved on the surface of the button shell 2, a rotating shaft 5 movably connected inside the mounting bracket 4, and a protective cover 6 installed on the surface of the rotating shaft 5. One side of the protective cover 6 is attached to the button shell 2. The protective cover 6 can block the call button 3 and play a protective role. The protective cover 6 is made of transparent PVC material, and the patient can see the call button 3 through the protective cover 6.

[0028] Example 2

[0029] Please see Figures 1-6 Based on Embodiment 1, the anti-accidental touch component also includes a spring 7 mounted on the surface of the rotating shaft 5. The spring 7 has the function of rotating energy storage. When the protective cover 6 is rotated, the protective cover 6 can drive the rotating shaft 5 to rotate and twist the spring 7. The other end of the spring 7 is fixedly connected to the inner wall of the mounting bracket 4. A connecting plate 8 is fixedly connected to the top of the mounting bracket 4. A clamping plate 9 is provided on one side of the connecting plate 8. A fixing screw 10 is provided on one side of the clamping plate 9. One end of the fixing screw 10 passes through the clamping plate 9 and is threadedly connected to the connecting plate 8. A knob 11 is fixedly connected to the other end of the fixing screw 10. The connecting plate 8 is connected by threads. When the mounting bracket 4 moves to the surface of the button shell 2, the threads can be used to move the clamping plate 9 to clamp the button shell 2, thereby fixing the protective cover 6. This facilitates the adaptation of different pager buttons 3. A wire 12 is installed on one side of the pager button 3, and the other end of the wire 12 is fixedly connected to the pager 1. A speaker 13 is installed on the front side of the button shell 2. A limit rod 14 is slidably connected inside the connecting plate 8. The limit rod 14 is slidably connected to the inner wall of the connecting plate 8, which can limit the movement of the clamping plate 9. The other end of the limit rod 14 passes through the connecting plate 8 and is fixedly connected to the clamping plate 9.

[0030] The working principle of this utility model is as follows: medical staff can manually move the mounting bracket 4 and put it on from the bottom of the button shell 2. The mounting bracket 4, together with the rotating shaft 5, drives the protective cover 6 to move. When the protective cover 6 blocks the call button 3, the knob 11 can be manually rotated. The knob 11, together with the clamp 9 of the fixing screw 10, moves and contacts the button shell 2 to achieve the function of fixing the protective cover 6.

[0031] The button cover 2 is moved to the patient's bedside for easy access. If the patient accidentally touches the button cover 2, the call button 3 is covered by the protective cover 6 to prevent accidental activation. When the patient needs to call medical staff, the patient can manually rotate the protective cover 6 upwards to remove the cover from the call button 3 and press the call button 3 to call medical staff. This will not affect the normal use of the call button 3 and will also improve the prevention of accidental activation.

[0032] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
