FIELD OF THE INVENTION

The present invention relates to healthcare communication systems, specifically a wireless communication device designed to enhance emergency and non-emergency communication between patients and healthcare staff in hospital settings. More particularly, the invention provides a system that allows patients, particularly those located in hallway beds or other non-traditional locations, to easily communicate with healthcare personnel through a portable, wireless device with integrated visual and audio features. The system improves the response time for medical assistance, increases patient safety, and streamlines the workflow of healthcare staff.

BACKGROUND OF THE INVENTION

Hospitals, especially emergency departments (EDs), are fast-paced environments where patient safety, prompt medical attention, and efficient communication are vital. The growing number of patients in need of immediate care often leads to overcrowded hospital settings, especially in emergency rooms where many patients are placed in hallway beds. Although these areas are meant to be temporary, they present a unique challenge for patient care, as hallway patients have no direct or easy way to contact medical personnel in times of distress.

Traditional hospital calls light systems, which allow patients to call for help with the push of a button, are generally limited to rooms where permanent beds and infrastructure are in place. These systems are not designed to accommodate overflow situations in hallways, often leaving patients at risk for delayed care, increased fall incidents, and missed medical emergencies. When hallway patients need assistance, they must rely on verbal calls or hope that a staff member is within earshot or passing by. This system's inefficiency can result in prolonged response times, causing increased frustration for patients and added stress for hospital staff.

Challenges in Emergency Department Communication Systems

In the fast-paced environment of an emergency department, timely and accurate communication is paramount. This ensures that patients receive care when needed and that staff is properly alerted to assist. However, the traditional call light system, while effective in rooms, does not account for hallway patients, leading to significant gaps in communication. This challenge is compounded by the following issues:

Emergency departments are often overcrowded, and it is not uncommon for patients to be placed in hallway beds. When this occurs, these patients have no dedicated means to communicate with the nursing staff or clerks overseeing the emergency room. Existing call light systems are restricted to patient rooms, and the design of these systems does not include hallway accessibility. In situations where hallway patients cannot press a call button, staff maybe unaware of urgent needs.

Studies have shown that delayed medical response is one of the leading causes of medical complications in hospital emergency settings. Specifically, hallway patients who cannot easily signal for help may experience increased wait times for assistance, leading to critical delays in their treatment. Furthermore, these patients may be at risk of falling or worsening medical conditions if assistance is not provided promptly.

The emergency department's medical staff, including nurses and clerks, are often overwhelmed with patient care tasks. Without an efficient communication system in place, these staff members must constantly monitor hallway patients, which detracts from their ability to attend to other high-priority cases. As a result, hallway patients are not provided with the necessary attention, contributing to delayed care and increased stress for medical staff.

In critical situations, such as when a patient experiences a cardiac arrest or severe respiratory distress, any delay in accessing timely medical care can be fatal. Traditional systems fail to adequately address urgent emergencies that require an immediate response, such as Code Blue (for life-threatening situations) or Rapid Response calls, which are not clearly distinguishable from standard calls for assistance in the existing hospital systems. Emergency buttons for situations like Code Blue are seldom implemented in the context of hallway bed patients, thus missing an essential component for critical care.

The development of a wireless communication device for patients in hallway beds is not entirely novel, as some prior art attempts to solve related problems, but each of these systems falls short in addressing the unique needs of overflow patients in the emergency department.

U.S. Patent Application Publication No. 2024/0038035, discloses a wireless patient call system that allows patients to communicate with medical staff. The system uses a portable device that places calls when a button is pressed. While the system is wireless, it primarily focuses on patient rooms and relies on existing hospital infrastructure to support its operation. Furthermore, it does not include the feature of a persistent light that remains on until manually turned off Additionally, this system lacks the ability to prioritize urgent calls, such as Code Blue or Rapid Response, and does not address hallway patients specifically.

Patent Application Publication No. KR20110099152, discloses a wireless medical communication device that enables patients to contact hospital staff by pressing a button. However, this system suffers from limited scope-it is primarily designed for patient rooms and does not accommodate the specific needs of hallway patients. Additionally, this patent does not provide a visual indicator that persists after the call is initiated, and it lacks distinct emergency response features for situations such as Code Blue.

In a study on hospital call systems, CARECOM developed to keep nurses happy and patients safe, it was emphasized that hallway patients remain underserved by current technologies. The study revealed that patients in hallway beds must rely on verbal calls for assistance, which are often not heard or responded to in a timely manner. Furthermore, the research indicated that existing systems do not offer visual alerts or a way for medical staff to know when hallway patients need help, which is especially important in high-traffic areas like emergency departments.

An article on Nurse Call System: Transform Patient Care with Iota Solutions suggested that colored lights (such as red or blue) could improve hospital communication by providing a visual cue for urgent situations. However, the study acknowledged that many current systems do not implement this technology effectively in hallway or temporary bed assignments. Moreover, manual reset of visual alerts is often overlooked, leading to confusion when multiple alerts are triggered simultaneously.

The present invention proposes a wireless communication device that provides a simple and effective means for hallway patients to request assistance. The device features a two-way communication system that allows patients to talk to hospital clerks or nurses in real time via a built-in speaker and microphone. Upon pressing a button, the device triggers a visual indicator that stays illuminated until manually turned off by the medical staff. The system also includes specialized emergency buttons for Code Blue and Rapid Response, which alert staff to the urgency of the situation through flashing lights and distinct calls.

The device is portable, making it easy for hospital staff to attach it to hospital beds, gurneys, or IV poles using a holding clip. It uses a hot-swappable battery for continuous operation, and its communication portal integrates with hospital systems to provide real-time tracking of all calls for help. This solution addresses the gaps left by traditional call light systems and is designed specifically to improve patient safety, reduce response times, and enhance hospital efficiency.

SUMMARY OF THE INVENTION

The present invention relates to a wireless communication system specifically designed for use in hospital environments where patients might be in temporary beds, hallway beds, or emergency room (ER) situations. This system aims to address the communication challenges between patients and medical staff, particularly when patients do not have easy access to traditional call systems found in designated patient rooms.

The invention provides an integrated communication tool that is not only wireless and portable but also simple to operate, ensuring immediate and efficient communication with medical staff during emergencies or routine requests. By incorporating, but not limited to a communication module with a button-activated call system, two-way speakerphone communication, a visual indicator light, and specialized emergency buttons, the invention ensures that patients in overflow or hallway beds can easily request assistance, with clear alerts sent to the appropriate medical staff for timely response.

This invention is particularly valuable in emergency settings where quick access to medical personnel can mean the difference between life and death. Additionally, it enhances hospital workflow, increases operational efficiency, and improves overall patient experience.

The heart of the system is the communication module, which enables the device to place calls and transmit signals wirelessly. This module is designed to connect to the hospital's central communication infrastructure (e.g., nurse call systems, electronic health records). When activated, the communication module transmits a signal to alert medical personnel, ensuring the patient's request is logged and the staff is aware of the situation.

The communication module can use Wi-Fi, Bluetooth, or RF communication protocols, making it flexible in terms of hospital network architecture. Its integration with hospital databases means it can trigger alerts, update patient status, and inform staff about ongoing requests, all in real-time.

The primary method by which the patient initiates communication is via the call button. This button can be placed directly on the patient's bed or attached to a flexible cord that the patient can hold or clip onto their clothing. Once pressed, the button sends a wireless signal to the communication module, indicating that the patient requires assistance.

The design of the call button is intuitive, ensuring ease of use for patients with varying levels of mobility or cognitive ability. The button is large enough to be pressed easily by patients in a variety of positions, including those who may be bedridden, elderly, or physically challenged. The device can also accommodate multiple buttons-including the standard call button, along with specialized buttons for emergency situations like Code Blue and Rapid Response.

The device is equipped with a speakerphone system to enable two-way communication between the patient and medical staff. This feature is essential for situations where the patient cannot physically interact with the device but needs to explain their condition. The speakerphone allows for a real-time conversation between the patient and hospital staff, allowing the latter to assess the urgency of the situation, offer instructions, or prioritize medical intervention.

The microphone and speaker system are designed to be high-quality, ensuring clear communication even in noisy hospital environments. The microphone is sensitive enough to pickup the patient's voice clearly, while the speaker is loud enough to be heard over ambient hospital noise. This feature improves the patient's ability to communicate vital information, such as pain levels, symptoms, or medical history, directly to the attending medical staff.

An innovative feature of the invention is the indicator light. When a call is initiated, a visual alert is activated. The light remains on until it is manually turned off by a member of the medical team, indicating that the request for assistance has been received and is being processed. This persistent visual indicator makes it easier for hospital staff to see if any patient requires attention, even if they are not in the immediate vicinity.

This indicator light provides an extra level of security, especially in high-traffic hospital environments where traditional call systems might go unnoticed or where staff cannot always hear auditory signals. The light can be placed on a variety of devices and is designed to remain visible from a distance, ensuring that staff are alerted to a patient's request no matter where they are in the hospital.

The device is equipped with dedicated emergency buttons designed for urgent situations like Code Blue (cardiac or respiratory arrest) or Rapid Response (for patients exhibiting deteriorating conditions). These buttons are easy to access and clearly marked, allowing patients to quickly signal life-threatening situations.

Pressing one of these emergency buttons sends an immediate alert to hospital staff with a higher priority than the regular call button, ensuring that critical situations are escalated appropriately. These emergency signals trigger special visual and audio alerts in the central hospital system, ensuring that medical teams are mobilized without delay.

The device operates on a rechargeable battery housed in a battery compartment. The power source is designed for long-term use, providing sufficient charge for extended periods without frequent recharging. This is particularly important in emergency room environments, where the device must function continuously, even during long shifts or busy hospital hours.

Additionally, the device is equipped with a low-battery warning system to alert medical staff when the battery is running low. This ensures that the device is always operational and ready for use when needed.

The device is designed to be portable, allowing it to be used in a variety of hospital settings. It can be mounted on a hospital bed, clipped onto a gurney, or placed on medical equipment such as IV poles or monitoring systems. This versatility ensures that patients can use the device in overflow beds, temporary beds, or emergency treatment areas where traditional call systems may not be available.

The mounting options make the device easy to use without requiring additional setup, reducing the burden on hospital staff and ensuring seamless integration into existing healthcare infrastructure. The design is intended to ensure that patients in any hospital location can use the device without confusion or difficulty.

One of the most powerful features of this invention is the centralized communication portal. This portal is integrated with the hospital's existing communication systems, allowing staff to manage all incoming calls, prioritize them based on urgency, and track responses in real time.

The portal enables the hospital to maintain an accurate record of patient calls and responses, helping to optimize resource allocation and improve patient care coordination. Staff can access the portal from any device, including smartphones, tablets, or hospital workstations, making it easy to respond to requests no matter where they are located.

The invention is designed to seamlessly integrate with a hospital's existing electronic health records (EHR) and nurse call systems. This means that when a call is made, it not only triggers an alert in the central system but also logs the request in the patient's medical record. This integration ensures that staff have access to relevant patient information in real time, allowing them to make informed decisions quickly.

Additionally, the integration with nurse call systems allows hospital staff to prioritize calls based on the patient's condition, ensuring that those requiring urgent medical intervention receive timely attention. The device is thus a vital tool in enhancing the efficiency and effectiveness of hospital operations, improving both patient care and the hospital's ability to manage high patient volumes.

Several other features can be incorporated into the device, depending on hospital needs. For example, the device can include a display screen to show important information such as the patient's name, the status of the call, or a brief description of the medical condition. This allows staff to quickly assess the situation before responding.

The system can also be upgraded with additional sensors, but not limited to, such as motion detectors or vital sign monitors, that provide real-time data to medical staff. For example, if a patient in distress presses the emergency button, the system could automatically send alerts that include the patient's heart rate, blood pressure, or oxygen saturation, enabling medical staff to take swift action.

Advantages of the Invention

The wireless communication tool significantly improves patient safety by providing a reliable and efficient means for patients to request help. The persistent indicator light ensures that medical staff are always aware of the patient's request, even when they are not within earshot. This leads to faster responses and fewer missed calls.

The light will remain on until it is manually deactivated by a staff member, ensuring that the request for help is visible to those in the vicinity, even if they are not directly near the device.

Simultaneously, the communication portal will display the patient's location, and medical staff will receive the alert. If necessary, the system can also alert specific medical personnel based on the severity of the request (e.g., code blue for emergencies or rapid response for urgent but non-critical issues).

Once the call is received at the communication portal, the medical staff can respond to the patient via the speaker and microphone on the device. This allows for two-way communication, where the healthcare provider can inquire about the patient's needs, provide instructions, or assess the situation.

The volume and clarity of communication are adjustable through the audio interface. Noise-canceling features ensure that the conversation remains clear even in noisy hospital environments.

If the situation is critical, the medical staff can press the code blue button or the rapid response button. This will activate a flashing blue or red light on the device and send an emergency signal to the communication portal, alerting the appropriate team.

The code blue button is specifically designed for emergency situations that require immediate intervention, such as cardiac arrest or other life-threatening conditions. The rapid response button is used for situations that are urgent but do not require the immediate, full-scale response associated with a code blue.

The device includes a battery compartment that must be checked regularly to ensure that the device is powered adequately. The rechargeable battery is designed to last through an entire shift, but staff must be vigilant about checking the battery life to ensure that it remains operational.

When the battery is low, the system will send a notification to the communication portal, alerting the staff to recharge or replace the battery as necessary. By following these steps, the wireless communication system ensures a smooth and efficient process for requesting and providing assistance in a hospital setting. The system is designed to be adaptable, easy to use, and reliable, making it a crucial tool for improving patient care and hospital workflows.

FIG. 13 illustrates two-way communication of the invention. Upon activation of the call button, an LED light is illuminated, signaling that the patient is requesting assistance.

The persistent visual indicator makes the communication system more reliable, especially in environments where patients may be out of direct line of sight of staff

FIG. 14 illustrates a separate flowchart demonstrating how the code blue button (114) and rapid response button (116) function. When a staff member presses the code blue button (114), the device automatically places a high-priority alert to hospital emergency teams. Similarly, pressing the rapid response button (116) sends an urgent but lower-priority alert. This embodiment emphasizes how the device enhances emergency response workflows in hospitals.

From FIG. 12-14, the wireless communication system works by creating a two-way communication channel between the patient and the medical staff. Below is a step-by-step breakdown of how the system operates:

Device Activation Upon patient placement in a hallway bed (136), a nurse or medical staff member assigns the device to the patient's bed. The patient call button (106) is mounted either on the device or on a flexible cord (110) that can be easily placed in the patient's reach. The nurse powers on the device by pressing the power button (112), and the system prompts the nurse to assign the device a name corresponding to the patient's bed number. For example, the nurse could name the device “Hallway 5” for a patient in bed 5. Once the name is confirmed, the device is ready for use.

Patient Call When the patient requires assistance, they simply press the patient call button (106) or the flexible cord button (110). This action sends an alert to the hospital communication system (1302). The alert triggers several actions:

The indicator light (102) turns on, signaling the need for assistance (1304).

A call is placed to the clerk or central desk (via radio (148) or Wi-Fi communication) to notify them of the patient's request (1306).

The patient's name and assigned bed number are announced to the clerk, such as “Call from Hallway 5.”

Communication with Medical Staff Once the call is received, the clerk can communicate with the patient using the built-in speaker (108) and microphone (144) on the device. This allows for clear and immediate communication, without the patient needing to shout or rely on staff hearing their verbal requests. The clerk can then relay the message to the appropriate medical personnel, such as a nurse or technician (1308-1314).

Urgent Requests for emergency situations, the patient or staff can press the Code Blue (114) or Rapid Response (116) buttons (1402). Upon activation:

The light on the device will flash the respective color (blue for Code Blue, red for Rapid Response) (1404).

A call will be made to the clerk desk, and the emergency message will be announced, such as “Code Blue Hallway 5” or “Rapid Response Hallway 5.” (1406-1408)

The staff is immediately made aware of the urgent situation and can proceed with an appropriate response (1410).

After the call has been placed, the indicator light remains on until manually turned off by a staff member. This feature ensures that the request is not overlooked, even if the clerk or nurse is occupied with other tasks. The manual override process is simple, requiring the staff to press the light on/off button located on the device.

The device is powered by a swappable battery located in the battery compartment (120). The swappable battery ensures that the device can be quickly recharged and ready for use. A charging base allows the device to be docked and charged when not in use, ensuring no downtime for critical communication.
