Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, specifically to an intelligent alarm device for medical care and its usage method. Background Technology

[0002] Currently, when patients or elderly people go to the toilet or take a walk in the hospital, some elderly people or patients with poor physical condition may experience sudden situations. Often, when such situations occur, the patients cannot be discovered quickly. By the time other people see the patient and notify the medical staff, the patient has missed the best treatment period due to the long discovery time. This may lead to the aggravation of the condition, and in severe cases, it may even endanger the patient's life, causing great inconvenience. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent alarm device for medical care and its usage method, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent alarm device for medical care, comprising a nursing bed body, monitoring components being provided on both the left and right sides of the nursing bed body, the monitoring components including a processor, a support frame, a protective frame, and a monitoring device, the support frame being mounted on the side of the nursing bed body, a protective plate being provided at the top front end of the support frame, one end of the protective frame being hinged to the rear end of the protective plate, a fixing frame being provided at the top rear end of the support frame, and a locking component being provided on the fixing frame for connecting to the other end of the protective frame, the monitoring device being slidably mounted on the top of the protective frame and driven to move by a power component, the monitoring device and the locking component being electrically connected to the processor, and when a wearing signal sent by the monitoring device is detected, the locking component is controlled to open;

[0005] The monitoring device includes a mounting base, a pager, and a watch strap. The mounting base is slidably mounted on a protective frame. A wearing opening is provided in the middle of the mounting base, and a fixing opening for the pager to be inserted and engaged is provided at the bottom of the wearing opening. Both ends of the pager are provided with locking slots, and both ends of the watch strap are provided with buckles corresponding to the locking slots. A wearing mechanism is provided in the upper part of the mounting base. The wearing mechanism is used to detachably connect with the buckles on both sides and drive the watch strap to move downward until the buckles are engaged in the locking slots. After the buckles are connected to the locking slots, a signal is sent to the processor.

[0006] Furthermore, push blocks are movably provided at both ends of the pager, and L-shaped locking blocks are provided at the top of the push blocks. The upper end of the locking blocks extends through into the locking slot. A return spring is connected between the push blocks and the inner wall of the pager. The buckle has a locking groove that matches the locking block. When the buckle is inserted into the locking slot, the locking block engages with the locking groove under the action of the return spring. First telescopic cylinders are provided at both ends of the fixed base. The piston rod of the first telescopic cylinder extends through to the side of the fixed opening and its end is connected to a pressure block. When the pager is placed in the fixed opening, the pressure block is aligned with the push block.

[0007] Furthermore, the wearing mechanism includes a second telescopic cylinder, a connecting frame, and two electromagnets. The second telescopic cylinder is assembled in the upper part of the fixed base, the connecting frame is installed on the piston rod of the second telescopic cylinder, and both ends of the connecting frame are provided with sliders. The sliders are slidably assembled on the wearing port side end, and the inner end faces of the two sliders are respectively provided with electromagnets. The outer end face of the buckle is embedded with a matching iron block.

[0008] Furthermore, the protective plate and the protective frame are connected by a torsion spring. When the torsion spring is in its initial state, the end face of the protective frame is precisely aligned with the corresponding reference surface of the fixed frame. The locking member is rotatably mounted on the end face of the fixed frame away from the nursing bed body. The locking member is provided with a limit rod. The fixed frame is provided with a first motor that is connected to the locking member and is electrically connected to the processor. The fixed frame is provided with a limit frame on the end face of the fixed frame near the nursing bed body. When the protective frame and the fixed frame are aligned, the limit frame abuts against the protective frame.

[0009] Furthermore, the power assembly includes a lead screw, a second motor, and a movable seat. The lead screw is rotatably mounted on the upper part of the protective frame and driven to rotate by the second motor. The movable seat is slidably mounted on the protective frame and threadedly connected to the lead screw. A base is provided on the top of the movable seat, and a circular opening is provided in the middle of the base. The fixed seat has a circular structure and is rotatably mounted in the opening. A gear ring is sleeved on the rear side of the outer surface of the fixed seat. A third motor is provided inside the base. A gear that meshes with the gear ring is provided on the output circumference of the third motor. An opening is provided on the upper part of the base, and the opening extends through to communicate with the opening.

[0010] Furthermore, a call button is provided at one end of the protective plate near the nursing bed body. The call button is electrically connected to the processor. Multiple sensors are provided on both the protective plate and the protective frame. When the call button is triggered for the first time, the second motor drives the moving seat to move to one side of the protective plate. When the call button and the caller are triggered in sequence, a first call signal is sent to the hospital management system. When the caller is triggered for a long time and the caller is not triggered within the preset time, a second call signal is sent. When the call button is triggered for a short time multiple times and the caller is not triggered within the preset time, a third call signal is sent.

[0011] Furthermore, the nursing bed body is equipped with several pressure sensors, the end of the call button that contacts the user's skin is provided with a flexible pad, and a disinfectant sprayer is provided on the support frame. When the fixed seat moves to the foremost side, the output end of the disinfectant sprayer is aligned with the wearing port; the call button integrates a three-axis accelerometer and a positioning chip.

[0012] Furthermore, base plates are detachably installed on both the left and right ends of the nursing bed body, and several cylinders are provided on each base plate. The support frame is installed on the piston rod of the cylinder on the corresponding side, and the cylinder is electrically connected to the processor.

[0013] The present invention also provides a method for using the above-mentioned intelligent alarm device for medical care, comprising the following steps:

[0014] S1. Routine protection: The protective panels on both sides of the nursing bed and the protective frame form a linked guardrail;

[0015] S2. Wearing off the bed: The patient inserts their wrist into the wearing port to trigger the wearing mechanism, and the watch strap automatically engages with the call button to complete the wearing process;

[0016] S3, Smart Unlock: After wearing, the processor is triggered to unlock the protective frame, allowing for safe exit from the bed;

[0017] S4. Emergency Call: Initiate emergency communication by directly connecting to the hospital management system via the call button while out of bed;

[0018] S5. Return to bed reset: Re-insert the strap into the wearing port to trigger the reverse operation, confirm the patient is back on the bed, and reset and lock the strap after it is removed.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention integrates mechanical structure, sensor network and intelligent algorithm to construct a closed-loop patient safety monitoring and alarm system. Through protective plates and protective frames, an active guardrail system is formed. When a patient is not wearing a call device, the locks are locked under the control of the processor to automatically restrict the patient from leaving the bed without wearing a call device, thus taking into account both safety and monitoring needs.

[0021] This invention achieves rapid and precise assembly of the caller and watchband through electromagnetic adsorption and mechanical linkage technology within the fixed base. Patients only need to put their hand into the wearing opening to automatically complete the wearing and removal, reducing the difficulty of operation for patients. Through the integration of multiple sensor data and active calling design within the caller, automatic monitoring is achieved during the patient's time away from the bed, and timely alarms can be triggered in case of sudden patient conditions, improving emergency response efficiency.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, an intelligent alarm device for medical care includes a nursing bed body. Monitoring components are provided on both the left and right sides of the nursing bed body. Each monitoring component includes a processor, a support frame, a protective frame, and a monitoring device. The support frame is mounted on the side of the nursing bed body. A protective plate is provided at the top front end of the support frame. One end of the protective frame is hinged to the rear end of the protective plate. A fixing frame is provided at the top rear end of the support frame. A locking device is provided on the fixing frame for connection to the other end of the protective frame. The monitoring device is slidably mounted on the top of the protective frame and is driven to move by a power component. Both the monitoring device and the locking device are electrically connected to the processor. When a wearing signal sent by the monitoring device is detected, the locking device is opened.

[0033] The monitoring device includes a mounting base, a pager, and a watch strap. The mounting base is slidably mounted on a protective frame. A wearing opening is provided in the middle of the mounting base, and a fixing opening for the pager to be inserted and engaged is provided at the bottom of the wearing opening. Both ends of the pager are provided with locking slots, and both ends of the watch strap are provided with buckles corresponding to the locking slots. A wearing mechanism is provided in the upper part of the mounting base. The wearing mechanism is used to detachably connect with the buckles on both sides and drive the watch strap to move downward until the buckles are engaged in the locking slots. After the buckles are connected to the locking slots, a signal is sent to the processor.

[0034] In this embodiment, push blocks are movably provided at both the left and right ends of the pager. An L-shaped locking block is provided at the top of the push block, and the upper end of the locking block extends through into the locking slot. A return spring is connected between the push block and the inner wall of the pager. A locking slot adapted to the locking block is provided on the buckle. When the buckle is inserted into the locking slot, the locking block engages with the locking slot under the action of the return spring. A first telescopic cylinder is provided at both the left and right ends of the fixed base. The piston rod of the first telescopic cylinder extends through to the side of the fixed opening and its end is connected to a pressure block. When the pager is placed in the fixed opening, the pressure block is aligned with the push block.

[0035] In this embodiment, the wearing mechanism includes a second telescopic cylinder, a connecting frame, and two electromagnets. The second telescopic cylinder is assembled in the upper part of the fixed base. The connecting frame is installed on the piston rod of the second telescopic cylinder, and both ends of the connecting frame are provided with sliders. The sliders are slidably assembled on the wearing opening side. The inner end faces of the two sliders are respectively provided with electromagnets, and the outer end face of the buckle is embedded with a matching iron block.

[0036] The wearing process of this device is as follows: The patient inserts his wrist into the wearing port of the fixed base. When the patient's wrist is detected (by means of infrared sensor, temperature sensor or vision sensor, etc.), the second telescopic cylinder drives the watch strap to move downward. After the buckle is inserted into the buckle of the caller, the first telescopic cylinder retracts. Under the action of the return spring, the push block embeds the buckle into the slot, completing the watch strap locking. Then the electromagnet is de-energized to eliminate the attraction. At the same time, a wearing signal is sent to the processor, and the patient can then pull his hand out of the wearing port.

[0037] The removal process of this device is as follows: After the patient inserts their wrist into the wearing port of the fixing seat, the patient's wrist is naturally placed on the wearing port, allowing the call device to slide into the fixing port. Then, the second telescopic cylinder drives the slider to descend and align with the buckle. The electromagnet is energized to attract the iron block on the buckle. The first telescopic cylinder extends and drives the pressure block to squeeze the push block, causing the buckle and the slot to separate. At the same time, the action of the pressure block pushing into the call device can fix the call device and prevent it from falling off when the fixing seat rotates. Finally, the second telescopic cylinder drives the strap to rise, and the patient can then remove their hand.

[0038] In this embodiment, the protective plate and the protective frame are connected by a torsion spring. When the torsion spring is in its initial state, the end face of the protective frame is precisely aligned with the corresponding reference surface of the fixed frame. The locking member is rotatably mounted on the end face of the fixed frame away from the nursing bed body. The locking member is provided with a limit rod. The fixed frame is provided with a first motor that is connected to the locking member and is electrically connected to the processor. The fixed frame is provided with a limit frame on the end face of the fixed frame near the nursing bed body. When the protective frame and the fixed frame are aligned, the limit frame abuts against the protective frame.

[0039] The protective frame maintains alignment accuracy through a torsion spring. After the patient pushes the protective frame away from the bed, it can rotate back to align with the fixed frame under the restoring force of the torsion spring, thus preventing the open protective frame from affecting the clinical area. The limit rod on the lock is controlled by the first motor to rotate and unlocks only after the processor confirms that the monitoring device is being worn. Since the lock is located on the outside, the patient on the bed cannot directly contact it, preventing the patient from leaving the bed without wearing the call device. However, family members outside the bed can directly turn the lock to unlock it, making it convenient for family members or doctors to enter and check on the patient in case of a sudden situation.

[0040] In this embodiment, the power assembly includes a lead screw, a second motor, and a movable seat. The lead screw is rotatably mounted on the upper part of the protective frame and driven to rotate by the second motor. The movable seat is slidably mounted on the protective frame and threadedly connected to the lead screw. A base is provided on the top of the movable seat, and a circular opening is provided in the middle of the base. The fixed seat has a circular structure and is rotatably mounted in the opening. A gear ring is sleeved on the rear side of the outer surface of the fixed seat. A third motor is provided inside the base. A gear that meshes with the gear ring is provided on the output circumference of the third motor. An opening is provided on the upper part of the base, and the opening extends through to communicate with the opening.

[0041] The fixed base can rotate under the drive of a third motor, so that when wearing it, the call device can be automatically rotated to the most suitable wearing angle by detecting the patient's wrist position, reducing the patient's discomfort. In addition, if the patient needs to use the call device directly in bed, the fixed port can be rotated to connect with the opening, at which time the patient can insert their fingers from the opening to operate the call device directly.

[0042] In this embodiment, a call button is provided at one end of the protective plate near the nursing bed body. The call button is electrically connected to the processor. Multiple sensors are provided on both the protective plate and the protective frame. When the call button is triggered for the first time, the second motor drives the moving seat to move to one side of the protective plate. When the call button and the caller are triggered sequentially, a first call signal is sent to the hospital management system. When the caller is triggered for a long time and is not triggered within the preset time, a second call signal is sent. When the call button is triggered for a short time multiple times and is not triggered within the preset time, a third call signal is sent.

[0043] When a patient needs to call while in bed, they should first press the call button located on the side of the bed. When the call button is triggered for the first time, the second motor drives the lead screw to move the monitoring device toward the bedside for easy operation by the patient. If the patient is conscious at this time, they can trigger a second call by inserting their hand into the opening and then into the fixed opening until it contacts the button on the surface of the call device.

[0044] First call signal: When the patient briefly presses the call button to manually trigger the caller, it indicates that the patient is still awake. The system determines that the patient has a routine nursing need (such as changing dressings), notifies the nursing station, but does not escalate the priority.

[0045] Second call signal: If the call button is pressed and held and there is no response within the preset time, the system determines that it is a device malfunction or patient misoperation and notifies the nurse station to check.

[0046] Third call signal: If the call button is pressed frequently (e.g., in case of emergency breathing difficulties) but the caller is not triggered, it means that the patient is no longer conscious and the alarm will automatically escalate to an emergency alarm, which will be linked to the ward broadcast and the on-duty doctor's terminal.

[0047] In this embodiment, the nursing bed body is equipped with several pressure sensors, the end of the call button that contacts the user's skin is provided with a flexible pad, and a disinfectant sprayer is provided on the support frame. When the fixed seat is moved to the foremost side, the output end of the disinfectant sprayer is aligned with the wearing port. The call button integrates a three-axis accelerometer and a positioning chip.

[0048] The call button has a built-in three-axis accelerometer to monitor the patient's movements in real time. If an abnormal fall, violent movement (such as struggling) or prolonged inactivity (such as unconsciousness) is detected, an alarm is triggered and the positioning chip synchronously uploads the patient's location information to the hospital management system.

[0049] When the call button is removed and the patient lies back on the nursing bed, the second motor drives the lead screw to move the monitoring device toward the head of the bed. When it moves to the frontmost position, the disinfectant sprayer sprays medical-grade disinfectant onto the wearing opening, thereby disinfecting the call button and the strap to prevent the growth of bacteria.

[0050] In this embodiment, base plates are detachably installed on both the left and right ends of the nursing bed body. Several cylinders are provided on each base plate. The support frame is installed on the piston rod of the cylinder on the corresponding side. The cylinder is electrically connected to the processor.

[0051] The entire monitoring unit can be raised and lowered by a cylinder. When the nursing bed is not in use or when transferring patients, the entire monitoring unit can be lowered to the same height as the bed surface, which facilitates operation.

[0052] This embodiment also provides a method for using the above-mentioned intelligent medical care alarm device, including the following steps:

[0053] S1. Routine protection: The protective panels on both sides of the nursing bed and the protective frame form a linked guardrail;

[0054] S2. Wearing off the bed: The patient inserts their wrist into the wearing port to trigger the wearing mechanism, and the watch strap automatically engages with the call button to complete the wearing process;

[0055] S3, Smart Unlock: After wearing, the processor is triggered to unlock the protective frame, allowing for safe exit from the bed;

[0056] S4. Emergency Call: Initiate emergency communication by directly connecting to the hospital management system via the call button while out of bed;

[0057] S5. Return to bed reset: Re-insert the strap into the wearing port to trigger the reverse operation, confirm the patient is back on the bed, and reset and lock the strap after it is removed.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
