Description

Technical Field

[0001] This utility model mainly relates to the field of medical device technology, specifically a fall protection device. Background Technology

[0002] In the field of medical device technology, fall prevention care for hospitalized patients (especially high-risk groups such as the elderly, those with limited mobility, and those with impaired consciousness) has always been a key focus and challenge in clinical nursing. These patients, due to limited mobility, balance disorders, or cognitive impairments, are prone to falls from bed or unauthorized walking during hospitalization (especially at night or when family members are briefly away). This can lead to injuries such as fractures and soft tissue damage, increase patient suffering, prolong hospital stays, and even cause serious medical safety incidents, placing a heavy burden on patients' families and medical institutions.

[0003] Currently, commonly used fall prevention measures in clinical practice include manual monitoring, bed rails, and restraints. However, manual monitoring is difficult to achieve 24-hour seamless coverage, leaving gaps in monitoring; while traditional bed rails provide some physical barrier, patients may climb over them or attempt to climb, still posing a risk of falling out of bed; conventional restraints suffer from poor comfort, inconvenient adjustment, and lack of early warning functions, making it difficult for medical staff to detect when patients forcibly break free or attempt to get out of bed, hindering proactive protection and timely intervention. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. It primarily offers a fall protection device to address the issues raised in the background section. Currently, commonly used fall prevention measures in clinical practice include manual monitoring, bed rails, and restraint straps. However, manual monitoring struggles to provide seamless 24-hour coverage, leaving gaps in monitoring. While traditional bed rails offer some physical protection, patients may attempt to climb over them, posing a risk of falls. Conventional restraint straps suffer from poor comfort, inconvenient adjustment, and a lack of warning functions, making it difficult for medical staff to detect when patients forcibly break free or attempt to get out of bed, hindering proactive protection and timely intervention.

The first connector assembly and the second connector assembly are attached together by magnetic attraction. A connecting strap is connected to one side of the first connector assembly, and the other end of the connecting strap is connected to the second connector assembly. A D-ring and a limiting ring are sequentially provided on the connecting strap. The first connector assembly is electrically connected to a controller via a cable.

[0006] The first connector assembly includes a first connector body. A first U-shaped block is connected to one side of the first connector body via a tension sensor. The tension sensor is used to sense the pulling force borne by the protective gear after it is locked. The first connector body is provided with a contact sensor and a first magnetic structure. The contact sensor is used to sense the locking state between the first connector assembly and the second connector assembly.

[0007] The second connector assembly includes a second magnetic structure adapted to the first magnetic structure, and the two cooperate with each other to achieve magnetic adsorption and locking.

[0008] More preferably, the second connector assembly includes a second connector body, a second U-shaped block is provided on one side of the second connector body, and a second magnetic structure is provided on the other side.

[0009] More preferably, an elliptical cylindrical guide boss is provided on one side of the second connector body, and a groove adapted to the elliptical cylindrical guide boss is provided at a corresponding position on the first connector body.

[0010] More preferably, the D-ring buckle and the limiting ring are symmetrically distributed about the vertical center line of the connecting strip, and the inner side of the limiting ring is provided with anti-slip texture.

[0011] More preferably, the controller is equipped with an alarm module and a wireless connection module.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This fall protection device achieves rapid docking of connector components through magnetic adsorption and structural guidance. It utilizes D-rings and limiting rings to flexibly adjust and fix the length of the device. Multiple safety warnings are provided through tension sensors, contact sensors, and loop monitoring. Local warnings and multi-terminal remote synchronous warnings are achieved through the controller's alarm module and wireless connection module. The overall structural design is convenient and efficient. Compared with traditional fall protection devices, it can effectively meet the safety protection needs of preventing patients from falling out of bed or getting out of bed without permission in scenarios such as hospital bed rails, improving the convenience, adaptability, and safety management efficiency of the device.

[0016] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Please refer to the appendix carefully. Figure 1-3 A fall protection device includes a first connector assembly 1 and a second connector assembly 2. The first connector assembly 1 and the second connector assembly 2 (with μ-metal alloy shields embedded in the first connector assembly 1 and the second connector assembly 2 to avoid magnetic interference with medical equipment) are magnetically attached. A connecting strap 3 is connected to one side of the first connector assembly 1, and the other end of the connecting strap 3 is connected to the second connector assembly 2. A D-ring buckle 4 and a limiting ring 5 are sequentially provided on the connecting strap 3. The first connector assembly 1 is electrically connected to a controller 6 through a cable.

[0019] In this embodiment, as Figure 2 As shown, the first connector assembly 1 includes a first connector body 101. One side of the first connector body 101 is connected to the first U-shaped block 102 through a tension sensor. The first connector body 101 is respectively provided with a contact sensor 103 (a low-current closed-loop circuit, with built-in electrode plates in the first connector assembly and corresponding contacts in the second connector assembly; the circuit is turned on after adsorption, and an impedance detection alarm is triggered when disconnected) and a first magnetic structure 104. The connecting strap 3 is threaded between the first U-shaped block 102 and the second U-shaped block 202. When the first connector assembly 1 and the second connector assembly 2 are engaged, if the connecting strap 3 is tightened to a preset degree (such as when a patient pulls on the connecting strap 3 while climbing), the alarm module of the controller 6 will be triggered to issue a warning even if the connectors are not separated, thus achieving a timely warning function. The contact sensor 103 built into the first connector body 101 will trigger an alarm when it detects that the connector is subjected to an abnormal separation force and is forcibly separated. When the two connectors are in contact with each other and locked, a closed loop is formed. If the loop is broken (i.e., the connecting strap 3 is untied), the alarm module will be triggered.

[0020] In this embodiment, as Figure 3 As shown, the second connector assembly 2 includes a second connector body 201. A second U-shaped block 202 is provided on one side of the second connector body 201, and a second magnetic structure 203 matching the first magnetic structure 104 is provided on the other side. The magnetic structure design adopts a strong magnet (the first magnetic structure 104 adopts N35 neodymium iron boron permanent magnet with a single-point adsorption force > 8N; the second magnetic structure 203 is a magnetically conductive soft iron) or an electromagnet. By utilizing the magnetic adsorption characteristics, the first connector assembly 1 and the second connector assembly 2 can automatically complete the initial positioning and adsorption when they are close to each other, reducing the manual alignment operation of medical staff, shortening the docking time, and improving the convenience of using protective gear.

[0021] In this embodiment, as Figure 2 and Figure 3 As shown, an elliptical cylindrical guide boss is provided on one side of the second connector body 201, and a groove adapted to the elliptical cylindrical guide boss is provided on the first connector body 101 at the corresponding position. The structure of the elliptical cylindrical guide boss and the matching groove provides clear guidance for the docking of the two connector components, avoiding misalignment or deviation during the docking process and ensuring the accuracy of the docking position. This reduces the operational difficulty for medical staff, enabling them to quickly complete the docking of the connector components, saving operation time. Furthermore, it forms a preliminary positioning after docking, enhancing the stability of the connector component fit and providing a basic guarantee for subsequent locking structures such as magnetic adsorption.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the D-ring buckle 4 and the limiting ring 5 are symmetrically distributed about the vertical center line of the connecting strip 3, and the inner side of the limiting ring 5 is provided with anti-slip texture; the threading path of the connecting strip 3 is as follows: one end first passes through the limiting ring 5, then passes through the D-ring buckle 4 and the first U-shaped block 102 in sequence, then turns back and passes through the D-ring buckle 4 and the limiting ring 5 again; the other end of the connecting strip 3 first passes through the limiting ring 5, then passes through the D-ring buckle 4 and the second U-shaped block 202 in sequence, and similarly turns back and passes through the D-ring buckle 4 and the limiting ring 5. The length of the protective gear can be easily adjusted using the D-ring 4. Furthermore, since both the first connector assembly 1 and the second connector assembly 2 are equipped with D-ring 4 and a limiting ring 5 on one side, medical personnel can flexibly adjust the size of the protective gear according to actual usage needs, improving operational adaptability. Simultaneously, the limiting ring 5 can slide along the connecting strap 3 to the end position, fixing the folded-back end of the connecting strap 3 to the main body, effectively preventing that end from being scattered.

[0023] In this embodiment, as Figure 1 As shown, the controller 6 is equipped with an alarm module and a wireless connection module; the alarm module includes an alarm light and a buzzer, and the wireless connection module integrates a Bluetooth / WiFi module. The controller 6 is also equipped with a control module and a power module. Through the wireless connection module, the real-time status information of the protective gear can be transmitted to the caregiver's mobile phone, the nurse station computer, or the ward nurse bell system, realizing multi-terminal synchronous early warning; the control module, as the core processing unit, can receive various sensor signals and trigger the alarm module to act—the alarm light can provide visual warning through flashing light, the buzzer can enhance the warning effect through sound prompts, and the power module provides stable power support for the operation of the entire protective gear, ensuring that all modules work together and improving the remote monitoring capability and emergency response efficiency of the protective gear.

[0024] The specific operating procedure of this utility is as follows: First, during the protective gear assembly stage, one end of the connecting strap 3 is passed through the limiting ring 5, the D-ring buckle 4, and the first U-shaped block 102 in sequence and then folded back, and the D-ring buckle 4 and the limiting ring 5 are passed through again; the other end is connected to the second U-shaped block 202 in the same way.

[0025] In a scenario where both side rails of the hospital bed are raised, when using the protective gear, the protective gear can be passed between the two side rails. Then, the elliptical cylindrical guide boss of the second connector body 201 aligns with the matching groove of the first connector body 101. With the adsorption force of the first magnetic structure 104 and the second magnetic structure 203, the first connector assembly 1 and the second connector assembly 2 can quickly complete the alignment and initial locking.

[0026] Next, the medical staff adjusted the effective length of the connecting belt 3 by adjusting the buckle 4, and slid the limiting ring 5 to the end of the connecting belt 3, using the inner anti-slip texture to fix the fold-back end and prevent it from falling apart.

[0027] During use, the control module of controller 6 acts as the core hub, receiving signals from various sensors in real time and coordinating the work of each module: when the connecting belt 3 is stretched to a preset degree due to external force (such as when a patient climbs and pulls on the guardrail or protective gear and tries to get off the bed), the tension sensor on one side of the first connector body 101 triggers a signal (when the preset threshold of the tension sensor is reached), and the control module drives the alarm module to issue a warning; if the first connector assembly 1 and the second connector assembly 2 are forcibly separated by an abnormal separation force (such as when a patient forcibly breaks free from the protective gear), the contact sensor 103 on the first connector body 101 sends a signal to trigger an alarm; the alarm module simultaneously provides visual and auditory warnings through flashing alarm lights and emitting a buzzer. Meanwhile, the controller 6's wireless connection module (Bluetooth / WiFi) transmits the real-time status of the protective gear (such as abnormal tension, joint separation, circuit disconnection, etc.) to the caregiver's mobile phone, the nurse station computer, and the ward nurse bell system (local storage for local caching of abnormal events (with timestamps)), enabling multi-terminal synchronous early warning. The power module provides stable power to the controller and various sensors, ensuring the continuous and efficient operation of the entire system. Ultimately, through the synergy of structural guidance, magnetic adsorption, sensor monitoring, intelligent early warning, and remote transmission, the protective gear achieves safety protection and convenient management functions in scenarios such as bed rails, forming a protective barrier to meet the needs of patients' family members to temporarily leave (such as to go to the toilet) or prevent patients from falling out of bed or getting out of bed on their own at night.
