Description

beds for critically ill patients

[0001] The present invention relates to a bed for critically ill patients, and more particularly, to a bed for critically ill patients that can assist in nursing critically ill patients who cannot move on their own or have difficulty moving.

[0002] Typically, hospitals and nursing homes have beds for critically ill patients, such as the elderly and patients who have difficulty moving around on their own, that can be used lying down or sitting down.

[0003] These beds for critically ill patients have a structure in which the backrest of the bed is angled vertically to raise the patient's upper body to a certain extent, depending on the purpose of use, such as sleeping, reading, or eating, or the backrest of the bed is angled horizontally to allow the patient's upper body to lie down.

[0004] However, in the case of severely ill patients with limited mobility, there was a concern that bedsores would develop or severe pain would occur as they would have to lie in bed for a long time, and guardians or caregivers would also frequently suffer from musculoskeletal disorders as they would have to perform repetitive physical labor such as changing sheets or changing the patient's position.

[0005] In addition, conventional beds for critically ill patients inevitably expose patients to the risk of their excrement being handled, which can cause psychological distress to patients. Furthermore, there is a risk that the patient's excrement may come into contact with the caregiver's body, making the excrement handling process unsanitary. Furthermore, various waste materials, such as bed sheets, diapers, and towels, are continuously generated, which can be costly and cause environmental pollution.

[0006] The purpose of the present invention is to provide a bed for seriously ill patients that can assist in nursing seriously ill patients who cannot move on their own or have difficulty moving.

[0007] A bed for a critically ill patient according to the present invention comprises a main body having an accommodation space formed therein, a plurality of oval-shaped rotating roller mat portions that can rotate at a set angle based on horizontal rotation centers on the left and right sides at the upper portion of the main body and are arranged horizontally in the front-back direction, a rotating driving portion that is mechanically connected to the axial direction of the rotating roller mat portions and rotates the rotating roller mat portions in a selected direction when driven, a washing portion that selectively sprays washing water and heated air to the upper and lower portions of the rotating roller mat portions when driven in a washing mode, and a control portion that receives driving power from the outside and controls the driving of the rotating driving portion and the washing portion, wherein the rotating roller mat portion is characterized in that it has an oval shape having a length on both axial sides and a length on both radial sides.

[0008] In addition, the above-mentioned rotating roller mat portion has radial sides having a length facing the same angle, and can rotate simultaneously when the above-mentioned rotating drive portion is driven.

[0009] In addition, the above-mentioned rotating roller mat portion has radial sides having a length facing forward and backward, and can rotate 180 degrees forward and backward at least once when driven.

[0010] In addition, the rotational driving unit may include a plurality of first gear members rotatably coupled to one or both axial sides of the first rotary mat, a plurality of second gear members rotatably coupled to one or both axial sides of the first horizontal mat, a plurality of third gear members rotatably coupled to one or both axial sides of the second rotary mat, a plurality of fourth gear members rotatably coupled to one or both axial sides of the second horizontal mat, a power transmission member mechanically coupled to the first gear member, the second gear member, the third gear member, and the fourth gear member to transmit rotational force, and a rotational motor that transmits rotational force to one axial side of one of the first gear member, the second gear member, the third gear member, and the fourth gear member.

[0011] In addition, the upper portion of the above-mentioned rotating roller mat portion may be provided so as to be openable on one side, and a cover portion may be further included so that a patient lying on the upper portion of the above-mentioned mat portion is positioned in the lower washing space, and the washing portion may selectively spray washing water and heated air inside the receiving space and the washing space.

[0012] In addition, the washing unit is arranged on one side of the receiving space, and is rotatable based on a horizontal rotation center in the left-right direction, and each of the transport rollers is spaced apart in the front-back direction, a ring-shaped transport belt that completely wraps around the radial direction of the transport roller and rotates together with the transport roller, a movable member that is coupled to the upper part of the transport belt and can reciprocate back and forth, an upper nozzle that is rotatably coupled to the upper part of the movable member at one lengthwise side, the spray section at the other side is positioned at the upper part of the rotating roller mat section, and a first discharge port is formed at the lower part of the spray section so as to be in communication with the first flow path therein, a lower nozzle that is coupled to the lower part of the movable member at one lengthwise side, the spray section at the other side is positioned at the lower part of the rotating roller mat section, and a second discharge port is formed at the upper part of the spray section so as to be in communication with the second flow path therein, a supply member that selectively supplies washing water and heated air to the first flow path and the second flow path, and a transport motor that transmits a rotational force to the rotational center of the transport roller. May include.

[0013] The present invention can reduce the physical and mental fatigue of the caregiver by allowing the patient to handle bowel movements, shower, and dry themselves without the help of a caregiver, can minimize body exposure, and can reduce the patient's shame. In addition, it can prevent bedsores in patients who lie down for a long period of time by allowing the patient to change their posture and skin pressure points without the help of a caregiver.

[0014] In addition, the present invention reduces the physical and mental burden on patients and their guardians or caregivers, thereby enabling a smoother and more continuous relationship with the patient, and reduces the financial burden and environmental pollution by not using various nursing supplies such as bedding and diapers that were essential for caring for seriously ill patients, resulting in the effect of reducing the time and cost required for care.

[0083] The first gear member (310), the second gear member (320), the third gear member (330), and the fourth gear member (340) may have a radial direction that forms a circumference, and a plurality of teeth may be formed along the radial direction. The power transmission member (350) may use a chain or belt that is connected in a state of wrapping around the radial direction of the first gear member (310), the second gear member (320), the third gear member (330), and the fourth gear member (340).

[0084] Here, the power transmission member (350) is a ring-shaped first power transmission member that is engaged while entirely wrapping around the radial direction of the first gear member (310) and simultaneously wrapped around the radial direction of the second gear member (320) located at the frontmost position and engaged, a ring-shaped second power transmission member that is engaged while entirely wrapping around the radial direction of the second gear member (320) and simultaneously wrapped around the radial direction of the third gear member (330) located at the frontmost position and engaged, a ring-shaped third power transmission member that is engaged while entirely wrapping around the radial direction of the third gear member (330) and simultaneously wrapped around the radial direction of the fourth gear member (340) located at the frontmost position and engaged, and a ring-shaped It may include a fourth power transmission member.

[0087] For example, when the drive shaft of the rotation motor (360) is rotated 180 degrees forward and backward, the first rotation mat (210), the first horizontal mat (230), the second rotation mat (240), and the second horizontal mat (260) can be rotated at the same angle toward the front and the rear, and can be rotated 180 degrees forward and backward simultaneously.

[0088] The washing unit (400) is for selectively spraying washing water (W) and heated air (A) to the upper and lower parts of the rotating roller mat unit (200) when driven in the washing and drying modes, and is provided on one side of the receiving space (110), and is rotatable based on a horizontal rotation center in the left and right directions, and includes a transport roller (410) that is spaced apart in the front and rear directions, a ring-shaped transport belt (420) that entirely wraps around the radial direction of the transport roller (410) and rotates together with the transport roller (410), a movable member (430) that is coupled to the upper part of the transport belt (420) and is capable of reciprocating forward and backward, an upper nozzle (440) that is rotatably coupled to the upper part of the movable member (430) on one side in the longitudinal direction, and in which the spray section on the other side is positioned on the upper part of the rotating roller mat unit (200), and in which a first discharge port (441) is formed on the lower part of the spray section so as to be in communication with the first flow path inside, and a longitudinal It may include a lower nozzle (450) in which one side is connected to the lower part of a moving member (430), the other side's injection section is located at the lower part of a rotating roller mat section (200), and a second discharge port (451) is formed at the upper part of the injection section so as to communicate with the second internal flow path, a supply member (460) that selectively supplies washing water (W) and heated air (A) to the first flow path and the second flow path, and a transfer motor (401) that transmits rotational force to the rotation center of the transfer roller (410).

[0089] The transfer roller (410) is mechanically connected to the drive shaft of the transfer motor (401) so that rotational force can be transmitted, and as the transfer roller (410) rotates in the forward / reverse direction, the moving member (430) can be reciprocated in the forward / reverse direction by a required distance.

[0099] As shown in Fig. 14, the supply member (460) has a storage space formed therein, and external air (A) and washing water (W) can be selectively supplied to the internal storage space through respective electric valves (463). Here, the storage space can be connected to an external first supply line to supply air (A), and can be connected to a second supply line to supply washing water (W).

[0100] And, the storage space of the supply member (460) may be connected to the first flow path of the upper nozzle (440) by the first connection line (471) and may be connected to the second flow path of the lower nozzle (450) by the second connection line (472). Here, the inside of the storage space may further include a heat exchange member (461) that is connected to the first supply line and wound in multiple pieces to rotate and move air (A) in the heated washing water, and the air (A) passing through the heat exchange member (461) may not only pressurize the storage space but also be heated by the heated washing water and moved to the first connection line (471) and the second connection line (472).

[0105] Here, a sliding member (510) that is coupled to the inside of the cover part (500) and can slide back and forth may be further included. In this case, a washing space may be formed at the bottom of the sliding member (510), and a curtain (520) may be coupled to the lower front side of the sliding member (510) to block washing water (W) from splashing out to the outside.

[0106] In addition, the outer surface of the sliding member (510) and the inner surface of the cover part (500) can be combined into a sliding structure with corresponding male and female sides. For example, when the sliding member (510) is moved rearward, the rear area of ​​the sliding member (510) can be inserted into the inside of the cover part (500) to raise the patient, and when the sliding member (510) is moved forward, the sliding member (510) can protrude forward to cover the upper body of the patient (10).

[0107] In addition, a concave mounting groove is formed on the upper surface of the cover portion (500) to accommodate a plate (150) or medical supplies for nursing. After the sliding member (510) is moved rearward, the first rotating mat (210) can be rotated upwards to be inclined, so that the patient (10) can eat using the plate (150) in a sitting position, and thus the upper surface of the cover portion (500) can also be used as a dining table.

[0110] In addition, the front panel (161) and the rear panel (162) may further include a microphone and a speaker (800), and the microphone and the speaker may be electrically connected to a nursing station, etc. In this case, the patient (10) or the caregiver may exchange various information (calls, etc.) with the nursing station using the microphone and speaker, or may further make calls or control using voice recognition, etc.

[0111] Meanwhile, a notification lamp (60) for externally displaying various notification signals may be installed on at least one of the front panel (161) and the rear panel (162) to display the patient and bed status in multiple colors, and a stand (50) may be installed on the upper part of one of the front panel (161) and the rear panel (162), and a manual cleaning gun (40) connected to the pressure supply member (480) described above and supplied with heated and pressurized cleaning water (W) and air (A) may be mounted on the stand (50). Here, the manual cleaning gun (40) has a structure in which the spraying of the cleaning water and air can be controlled by operating a lever through a manual selection switch (801), and can be used to wash a patient's head or clean a bed.

[0112] In addition, it may further include an air filter (180) installed inside the rear panel (162) to filter the air inside the washing space while allowing it to pass through, an intake port (171) that is connected from the front of the rear panel (162) to the inlet side of the air filter (180) and moves air to the inlet side of the air filter (180) when the air filter (180) is driven, and an exhaust port (172) that is connected from the front of the rear panel (162) to the outlet side of the air filter (180) and discharges air that has passed through the air filter (180) into the washing space.

[0113] In addition, a blower (not shown) for forcibly moving air may be installed in at least one of the intake port (171) and the exhaust port (172). That is, since the internal air (A) of the washing space is filtered by the air filter (180) and re-introduced into the washing space through the exhaust port (172), the air quality of the washing space can be maintained clean, and any remaining odor inside the washing space can be quickly eliminated.

[0114] Meanwhile, a thermal imaging camera (700) may be further incorporated into the front inner surface of the rear panel (162). The thermal imaging camera (700) can detect the patient's (10) posture, body temperature, ambient temperature, degree of defecation, type, number of defecations, and location in real time and transmit the information to the control unit (600). The control unit (600) stores and controls the measurement information transmitted from the thermal imaging camera (700) and transmits the information to a management server or the like as data necessary for patient management.

[0115] As a result, the present invention can reduce the physical and mental fatigue of the caregiver by allowing the patient (10) to handle bowel movements, shower, and dry, minimize body exposure, reduce the patient's shame, and prevent bedsores in patients who lie down for a long period of time by allowing the patient's posture and skin pressure points to change without the help of the caregiver.

[0116] In addition, the present invention reduces the physical and mental burden on patients and caregivers or caregivers, thereby enabling a smoother and more continuous relationship with patients, and reduces the financial burden and environmental pollution by not using various nursing supplies such as bedding and diapers that were essential for caring for critically ill patients, thereby ultimately reducing the time and cost required for care.
