Description

Fall prevention bed

[0001] The present invention relates to a fall prevention bed, and more specifically, to a fall prevention bed that can prevent falls by judging the user's movements.

[0002] In modern society, the elderly population is increasing due to improvements in overall living standards and advancements in medicine. Consequently, various types of falls, including slips, accidents on stairs, falls in bathrooms, and falls from bed, are occurring frequently. Among these, bed falls often result in fractures and can be fatal for the elderly. For example, Republic of Korea Patent No. 10-2199630 (January 8, 2021) discloses a fall prevention bed that incorporates a detachment prevention member installed on the bed frame to prevent falls.

[0003] However, in the conventional cases described above, patients who are unable to communicate, such as those with hemiplegia, post-stroke sequelae, Parkinson's disease, dementia, or delirium, or patients with severe cognitive impairment, are unaware of the risk of falling and attempt to move beyond the side rail, leading to a fall accident. In other words, a fall from the height of the side rail to the floor can result in a femoral fracture, etc., and if not properly treated, there is a problem that the possibility of death within two years is approximately 70%, and the mortality rate within two years after surgery is approximately 30%. In addition, there was the problem of there being no device to protect the patient's body in the event of a fall.

[0004] The present invention has been devised to solve the problems of the prior art as described above, and its purpose is to provide a fall prevention bed that can prevent falls by judging the user's movements and protect the user's body in the event of a fall.

[0005] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems to be solved by the present invention that are not mentioned herein will be clearly understood by a person having ordinary skill in the technical field to which the present invention pertains from the description below.

[0006] In a fall prevention bed according to a preferred embodiment of the present invention, the bed includes a bed portion, side rail portions provided on each side of the bed portion along the longitudinal direction of the bed portion, and a detection module provided on the upper portion of the side rail portion to detect the movement of a user, wherein the detection module is characterized in that it is detachable from the side rail portion.

[0007] In addition, the detection module according to a preferred embodiment of the present invention is characterized by including a frame portion provided along the longitudinal direction of the side rail portion and having an empty space formed therein, and a detachable portion formed by extending from the frame portion and provided in a form that surrounds the outer circumference of the side rail portion, so that the frame portion can be detached from the side rail portion.

[0008] In addition, the frame part according to a preferred embodiment of the present invention includes a cushion provided inside the frame part, and contact terminals provided on the upper and lower parts of the inner surface of the frame part, respectively, and in normal times, the contact terminals are kept spaced apart by the cushions, and when the frame part is pressed by the movement of the user and the cushions are compressed, the contact terminals are brought into contact.

[0009] In addition, according to a preferred embodiment of the present invention, the present invention further comprises a control unit that predicts the movement of the user based on the measurement value of the detection module, and an alarm unit that generates a warning signal that can be recognized through the five senses according to a control signal of the control unit.

[0010] In addition, according to a preferred embodiment of the present invention, the control unit is characterized in that, when the measurement value of the detection module is continuously transmitted for a preset period of time, the alarm unit is controlled to generate a warning signal.

[0011] By means of solving the above problem, the fall prevention bed of the present invention is effective in providing a fall prevention bed that can prevent a fall by judging the movement of the user and protect the body of the user in the event of a fall.

[0012] In addition, the fall prevention bed of the present invention has an advantage in that the plurality of cushions and contact terminals are arranged alternately to support the entire frame evenly, thereby preventing the contact terminals from coming into contact without external pressure.

[0013] In addition, the fall prevention bed of the present invention has an advantage in that the control unit controls the alarm unit to generate an alarm signal when pressure is measured through the contact terminal first, and then controls the shock absorbing unit to unfold when the continuously measured pressure gradually increases, thereby protecting the user's body when falling.

[0014] In addition, the fall prevention bed of the present invention has an advantage in that, when the measured value of the detection module exceeds a preset increase per unit time, the patient is gradually lifting his / her body onto the side rail, and the weight measured through the detection module is increasing, so that there is a risk of the patient falling over the side rail, so that the shock absorbing part is unfolded to protect the user's body in case of a fall.

[0015] In addition, the fall prevention bed of the present invention prevents falls that are the most serious among falls, such as falls over side rails, thereby contributing to the physical and mental health of patients and their families as well as the health of the nation.

[0024] The terms used in this specification will be briefly explained, and the present invention will be described in detail.

[0025] The terms used in this invention have been selected from widely used, common terms, taking into account their functions. However, these terms may vary depending on the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. Therefore, the terms used in this invention should be defined based on their meaning and the overall content of the invention, rather than simply their names.

[0026] When a part of a specification is said to “include” a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0027] Below, with reference to the attached drawings, embodiments of the present invention are described in detail so that those skilled in the art can easily implement them. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

[0028] Specific details, including the problems to be solved, means of solving them, and the effects of the invention, are included in the embodiments and drawings described below. The advantages and features of the present invention, and methods for achieving them, will become clearer with reference to the embodiments described below in detail, along with the accompanying drawings.

[0029] Hereinafter, the present invention will be described in more detail with reference to the attached drawings.

[0030] Referring to FIGS. 1 and 2, a fall prevention bed according to a preferred embodiment of the present invention includes a bed portion (100), side rail portions (200) provided on both sides of the bed portion (100) along the longitudinal direction of the bed portion (100), a detection module (300) provided on the upper portion of the side rail portion (200) to detect the movement of a user, a control portion (400) to predict the movement of the user based on the measurement value of the detection module (300), an alarm portion (500) that generates a warning signal that can be recognized through the five senses according to a control signal of the control portion (400), and a shock absorbing portion (600) provided on one side of the bed portion (100) and unfolded according to a control signal of the control portion (400).

[0031] First, the bed (100) is provided. The bed (100) is a bed furniture provided for the user to lie down on. For example, the bed has a length of 200 cm and a width of 80 cm. In the case of a mobile bed with wheels attached to the bottom of the bed frame for transporting a typical patient, the length may be provided to be 190 cm.

[0032] Next, the side rail part (200) is provided. The side rail part (200) is formed by extending upward from both sides of the bed part (100) and serves to prevent the user from falling to the left and right. For example, the plurality of vertical pillar frames of the side rail part (200) may be 36 cm, the interval between pillar frames and adjacent pillar frames may be 25 cm, the left and right rail frames provided on the upper portion of the pillar frames may be formed to be 113 cm, and the side rail part (200) may be provided in a foldable manner.

[0033] Next, the detection module (300) is provided. The detection module (300) is provided on the upper portion of the side rail portion and serves to detect the movement of the user. At this time, the detection module (300) is detachably attached to the side rail portion (200). In addition, the detection module (300) may include a pressure sensor, a temperature sensor, or a light sensor for detecting the movement of the user.

[0034] More specifically, referring to FIGS. 3 and 4, the detection module (300) includes a frame portion (310) provided along the longitudinal direction of the side rail portion (200) and having an empty space formed therein, and a detachable portion (320) formed by extending from the frame portion (310) and provided in a form that surrounds the outer circumference of the side rail portion (200), thereby allowing the frame portion (310) to be detachably attached to the side rail portion (200).

[0035] For example, the frame part (310) may be formed of an elastic material and is formed in a plate shape with rounded corners in a shape corresponding to the upper surface of the side rail part (200). In addition, both ends of the frame part (310) are formed by being bent downward in a shape that surrounds at least a portion of the outer circumference of the side rail part (200), and the bent portion is formed to be rounded. In addition, the detachable part (320) is formed by extending from both ends of the frame part (310) and may be formed of a cloth or non-woven material. In addition, an adhesive, a hook-and-loop fastener, or a Velcro fastener may be provided at the end of the detachable part (320) so that both ends of the detachable part (320) can be coupled, and a fixing device such as a button or a pushpin may be included.

[0036] Meanwhile, the frame part (310) includes a cushion (311) provided on the inside of the frame part (310) and contact terminals (312) provided on the upper and lower portions of the inner surface of the frame part (310), and in normal times, the contact terminals (312) are maintained in a spaced state by the cushion (311), and when the frame part (310) is pressed by the movement of the user and the cushion (311) is compressed, the contact terminals (312) come into contact. For example, when the frame part (310) is pressed by the movement of the user and the cushion (311) is compressed and the contact terminals (312) come into contact, the contact terminals (312) measure the pressure and transmit the measured value to the control part (400). Here, the cushion (311) may be, for example, a sponge or a spring, and may be provided in any form as long as it can support the frame portion (310) so as to block contact of the contact terminal (312) in normal times.

[0037] At this time, the cushions (311) may be provided in multiple numbers spaced apart at regular intervals along the longitudinal direction of the frame portion (310), and the contact terminals (312) may also be provided in multiple numbers spaced apart at regular intervals along the longitudinal direction of the frame portion (310), and the plurality of cushions (311) and the contact terminals (312) may be arranged alternately. Accordingly, the plurality of cushions (311) are provided so as to evenly support the entire frame portion (310), which has the advantage of preventing the contact terminals (312) from coming into contact in a state where there is no external pressure.

[0038] Next, the control unit (400) is provided. The control unit (400) receives and stores the measurement values ​​of the detection module (300), and predicts the user's movement based on the measurement values ​​of the detection module (300) to control the alarm unit (500) and the shock absorbing unit (600).

[0039] More specifically, the control unit (400) controls the alarm unit (500) to generate a warning signal when the measurement value of the detection module (300) is continuously transmitted for a period exceeding a preset time. For example, the control unit (400) measures the time that the frame unit (310) is pressurized and the contact terminal (312) is in contact, and receives and stores the pressure measurement value of the contact terminal (312). At this time, when the measurement value of the detection module (300) is continuously transmitted for a period exceeding a preset time, the user may be judged to have placed his or her body on the upper portion of the side rail unit (200) and the alarm unit (500) may be controlled to generate a warning signal.

[0040] Next, the alarm unit (500) is provided. The alarm unit (500) may be installed in the vicinity of the bed unit (100) in multiple units, or may be installed in a nurse's station or management office of a hospital, spaced apart from the bed unit (100), and serves to generate a warning signal that can be recognized by a nearby person through the five senses according to a control signal of the control unit (400), such as vibration, light irradiation, or sound generation. In addition, the alarm unit (500) can transmit a danger signal through wireless communication with a monitor in a central control room where professional nursing personnel are stationed, and includes a function to contact a person in charge or an institution that can provide direct assistance to the patient, such as a nurse, a caregiver, a guardian, or a support organization, by utilizing a smart device, the Internet of Things (IoT), etc.

[0041] Next, the shock absorbing unit (600) is provided. The shock absorbing unit (600) is expanded according to the control signal of the control unit (400) to support the user's body when the user falls. For example, referring to FIG. 5, the shock absorbing unit (600) may be provided on the lower portions of both sides of the bed unit (100) so as to be expanded in the outward direction of the bed unit (100). In addition, the shock absorbing unit (600) may be provided on the lower portions of both sides of the bed unit (100) so as to be expanded according to the control signal of the control unit (400) to correspond to the contact terminal (312) on the side rail unit (200). At this time, the shock absorbing unit (600) may be formed as an airbag, for example.

[0042] As a result, the pressure applied to the frame part (310) through the contact terminal (312) is continuously measured, and when the pressure applied to the frame part (310) exceeds a preset pressure, the control unit (400) controls the alarm part (500) to generate an alarm signal. In addition, when the pressure measurement value of the contact terminal (312) gradually increases, the control unit (400) controls the shock absorbing part (600) to unfold. In other words, the control unit (400) first controls the alarm part (500) to generate an alarm signal when the pressure is measured through the contact terminal (312), and then controls the shock absorbing part (600) to unfold when the continuously measured pressure gradually increases, thereby providing an advantage in protecting the user's body when falling.

[0043] Meanwhile, referring to FIG. 6, the contact terminals (312) may be provided in multiple numbers, and may be arranged more densely toward both ends of the frame portion (310). For example, when the user crosses the side rail portion (200), the user's arms and legs are first placed on the upper portion of the side rail portion (200), so that the density of the contact terminals (312) at both ends of the frame portion (310) corresponding to the user's arms and legs is increased, thereby enabling faster and more accurate movement detection.

[0044] In addition, the control unit (400) can control the shock absorbing unit (600) to unfold and at the same time generate an alarm signal from the alarm unit (500) when the sum of the measured values ​​of each of the plurality of contact terminals (312) exceeds a preset value. That is, when a high pressure exceeding a preset pressure value is temporarily detected from the plurality of contact terminals (312) near both ends of the frame unit (310) corresponding to the user's arms and legs, it is determined that a fall is imminent and the shock absorbing unit (600) unfolds, thereby protecting the user's body when the user falls.

[0045] Hereinafter, the operation and control method of the fall prevention bed of the present invention will be described in detail with reference to the attached drawings.

[0046] Referring to FIG. 7, the detection module (300) detects the user's movement. At this time, the detection module (300) detecting the user's movement means that pressure is measured through the contact terminal (312) and transmitted to the control unit (400). Thereafter, the control unit (400) determines whether the user's movement is detected based on whether pressure is measured from the contact terminal (312). Here, if the control unit (400) determines that the user's movement is not detected, the detection module (300) continuously detects the user's movement. In addition, if the control unit (400) determines that the user's movement is detected, the time for which the measurement value of the detection module (300) is transmitted is continuously measured. That is, the time for which pressure is detected from the detection module (300) is measured. Thereafter, the control unit (400) determines whether the measured time exceeds a preset time. At this time, if the control unit (400) determines that the measured time does not exceed the preset time, it controls the detection module (300) to continuously detect the user's movement again. In addition, if the control unit (400) determines that the measured time exceeds the preset time, it controls the alarm unit (500) to generate the warning signal. That is, even if the state in which a patient lying on the bed unit (100) simply places his / her body on the side rail unit (200) is detected through the detection module (300), if the transmission of the measured value from the detection module (300) does not exceed the preset time from the time of detection, the warning signal is not generated. In addition, if the measurement value of the detection module (300) is continuously transmitted exceeding the preset time, the control unit (400) controls the alarm unit (500) to generate a warning signal.

[0047] And, after the control unit (400) determines that the measured time exceeds the preset time and the alarm unit (500) generates the warning signal, the control unit (400) determines whether the measured value of the detection module (300) exceeds the preset increase per unit time. At this time, if the control unit (400) determines that the measured value of the detection module (300) does not exceed the preset increase per unit time, the control unit (400) causes the detection module (300) to detect the user's movement again. In addition, if the control unit (400) determines that the measured value of the detection module (300) exceeds the preset increase per unit time, the control unit (400) causes the shock absorbing unit (600) to unfold. That is, if a patient lying on the bed (100) places his / her body on the side rail (200), and the body is continuously placed on the side rail (200) and the pressure measurement value of the detection module (300) gradually increases, it is determined that the body is placed on the side rail (200). In other words, if the measurement value of the detection module (300) exceeds a preset increase per unit time, it means that the patient is gradually placing his / her body on the side rail (200), and the weight measured through the detection module (300) is increasing. Therefore, the shock absorbing unit (600) is unfolded because there is a risk of the patient falling over the side rail (200).

[0048] As a result, the fall prevention bed of the present invention has the advantage of being able to prevent falls by judging the user's movements and protecting the user's body in the event of a fall.

[0049] In this way, it will be understood by those skilled in the art that the technical configuration of the present invention described above can be implemented in other specific forms without changing the technical idea or essential features of the present invention.

[0050] Therefore, the embodiments described above should be understood as being exemplary and not restrictive in all respects, and the scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
