Description

Technical Field

[0001] The utility model relates to the technical field of nursing equipment, especially to the field of nursing beds, and specifically refers to a multifunctional nursing bed. Background Art

[0002] As an important medical nursing equipment, nursing beds are widely used in medical institutions and elderly care institutions.

[0003] In actual application scenarios, most users of nursing beds are patients or the elderly with limited mobility, and they often need the care of nursing staff in daily life. If the functions of the nursing bed are not perfect, it will directly reduce the comfort level of patients or the elderly during use, and at the same time increase the labor intensity of nursing staff and the nursing cost of patients or the elderly.

[0004] Most traditional nursing beds have relatively simple functions and can only simply adjust the angles of the bed boards at the head and back positions and the lower limb positions of the user. With the development of technology, some existing nursing beds currently have the function of body turning. However, these nursing beds still have some problems in actual use. For example, the nursing bed cannot turn the body when the user is in a semi-recumbent posture. For patients or the elderly with symptoms of dyspnea or suffering from diseases such as spine, waist, and back and unable to lie flat, the nursing staff still needs to manually turn the body; when the user is adjusted from a supine posture to a semi-recumbent posture, there will be mutual friction between the body and the head and back bed board, and at the same time the body will slide towards the end of the bed. These problems will not only lead to a decrease in the comfort of the user, but also increase the labor intensity of the nursing staff. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a multifunctional nursing bed that can reduce the labor intensity of nursing staff and the nursing cost of patients.

[0006] The utility model is realized through the following technical solutions. A multifunctional nursing bed is provided, including a bed body assembly and a central frame. The central frame is hinged to the bed body assembly. The central frame is provided with a turning plate mechanism, a side turning mechanism, a head and back turning mechanism, a lower limb turning mechanism, a head and back follow-up mechanism, a stop-falling mechanism, a side protection mechanism, and a bedpan moving mechanism. The turning plate mechanism includes a first turning plate hinged to the central frame.

[0007] The head and back turning mechanism includes a second telescopic device, and the second telescopic device is respectively hinged to the central frame and the first turning plate.

[0008] The head and back follow-up mechanism includes a follow-up plate. The first turning plate is connected with a third optical axis, and the follow-up plate is slidably connected to the third optical axis through a third linear bearing.

[0009] The head and back follow-up mechanism further includes a traction assembly and a first spring sleeved on the third optical axis. Two ends of the first spring are respectively connected to the third linear bearing and the first turning plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The angles of the head and back and the lower limbs of the patient can be adjusted through the head and back turning mechanism and the lower limb turning mechanism, so as to change the lying posture of the patient and improve the comfort of the patient.

[0012] 2. During the process of the patient adjusting from the supine posture to the semi-recumbent posture, the head and back follow-up mechanism can prevent relative displacement between the turning plate mechanism and the back of the patient, thus avoiding the turning plate mechanism from rubbing the back of the patient. At the same time, through the anti-falling mechanism, it can prevent the patient from slipping towards the end of the nursing bed, further improving the comfort of the patient and avoiding accidental injuries that may be caused to the patient when slipping towards the end of the bed.

[0013] 3. Through the side turning mechanism, the overall turning of the central frame and the turning plate mechanism, the head and back turning mechanism, the lower limb turning mechanism, the head and back follow-up mechanism, the anti-falling mechanism, the side protection mechanism, and the bedpan moving mechanism arranged on the central frame can be realized, thus realizing the turning function when the patient is in the semi-recumbent posture. For patients with symptoms of dyspnea or suffering from diseases such as spine, waist, and back and unable to lie flat, or the elderly, when the nursing staff performs body massage or nursing cleaning on them, there is no need to turn the body manually anymore. At the same time, when the patient turns over, there is no need for multiple nursing staff to cooperate to sort out medical devices such as wire harnesses, pipelines, and needles on the patient, greatly reducing the labor intensity of the nursing staff and the nursing cost of the patient.

[0014] 4. Through the side protection mechanism, it can prevent the patient from slipping towards the side of the head of the nursing bed when the patient is in the semi-recumbent posture and when turning the body in the semi-recumbent posture.

[0015] 5. Through the bedpan moving mechanism, the blockage of the excretion port of the nursing bed can be automatically removed when the patient excretes, and the bedpan can be moved to the excretion port of the nursing bed. When the patient finishes excreting, the bedpan can be moved to the side of the nursing bed, and at the same time, the excretion port of the nursing bed can be automatically blocked. Therefore, there is no need for the nursing staff to bend down and reach under the bed to pick up and place the bedpan and manually block or open the excretion port of the nursing bed, further reducing the labor intensity of the nursing staff.

[0016] Preferably, the turning plate mechanism further includes a second turning plate which is hinged to the first turning plate. The side guard mechanism includes a fifth connecting member, a sixth connecting member and a side guard shaft. The fifth connecting member is hinged to the center frame and the sixth connecting member respectively. The side guard shaft is fixedly connected to the sixth connecting member and hinged to the first turning plate. The side guard shaft is connected with a third roller which is in rolling connection with the second turning plate.

[0017] The beneficial effects of adopting the above preferred technical solution are as follows: when the first turning plate rotates, the side guard shaft and the third roller can be driven to rotate through the fifth connecting member and the sixth connecting member. During the rotation of the third roller, since the second turning plate is hinged to the first turning plate, the second turning plate can be driven to rotate towards the patient's side, so that the second turning plate can protect the side of the patient and prevent the patient from slipping off from one side of the nursing bed.

[0018] Preferably, the turning plate mechanism further includes a third turning plate which is hinged to the center frame. The bed body assembly is provided with a first roller. Both the second turning plate and the third turning plate are in rolling connection with the first roller.

[0019] The beneficial effects of adopting the above preferred technical solution are as follows: when the turning plate mechanism rotates with the center frame, friction between the second turning plate, the third turning plate and the bed body assembly can be avoided through the first roller.

[0020] Preferably, the side turning mechanism includes a first telescopic device which is hinged to the center frame and the bed body assembly respectively.

[0021] Preferably, the turning plate mechanism further includes a fourth turning plate, a sixth turning plate and a first turning frame. Both the fourth turning plate and the sixth turning plate are hinged to the center frame and the first turning frame respectively. The lower limb turning mechanism includes a third telescopic device which is hinged to the center frame and the sixth turning plate respectively. The connection line between the hinge axis of the fourth turning plate and the hinge axis of the sixth turning plate forms a parallelogram.

[0022] The beneficial effects of adopting the above preferred technical solution are as follows: since the connection line between the hinge axis of the fourth turning plate and the hinge axis of the sixth turning plate forms a parallelogram, it can be ensured that when the third telescopic device drives the first turning frame to move through the sixth turning plate, the first turning frame will not rotate.

[0023] Preferably, a first spring is sleeved on the third optical axis. Two ends of the first spring are respectively connected to the third linear bearing and the first turning plate. The head and back follow-up mechanism further includes a traction assembly. The traction assembly includes a traction rope and a second spring hinged to the first turning plate. The second spring is connected with a first pulley. The first turning plate is connected with a second pulley and a third pulley. One end of the traction rope is connected to the center frame. The other end of the traction rope passes around the first pulley, the second pulley and the third pulley and is connected with the follow-up plate.

[0024] The beneficial effects of adopting the above preferred technical solution are as follows: Through the traction rope, during the process of the patient changing from a lying posture to a semi-recumbent posture, as the first turning plate rotates, the second spring generates a pulling force on the follow-up plate, thereby offsetting the gravity of the follow-up plate itself and the elastic force of the first spring. Thus, by applying a frictional force to the follow-up plate through the patient's back, the follow-up plate can easily move along the third optical axis to the front side of the first turning plate, avoiding the back of the patient being rubbed against the back muscles of the first turning plate due to relative displacement between the back and the first turning plate.

[0025] Preferably, the anti-falling mechanism includes a swing frame, an anti-falling plate and a fourth connecting member. The swing frame is hinged to the center frame. The swing frame is connected with a second roller. The anti-falling plate is hinged to the center frame and is in rolling connection with the second roller. The fourth connecting member is respectively hinged to the first turning plate and the swing frame.

[0026] The beneficial effects of adopting the above preferred technical solution are as follows: During the process of the patient changing from a lying posture to a semi-recumbent posture, as the first turning plate rotates, the first turning plate makes the swing frame rotate around the hinge axis between the swing frame and the center frame through the fourth connecting member, and then drives the anti-falling plate to rotate through the second roller, raising the patient's legs, thereby achieving the purpose of preventing the patient from slipping towards the end of the nursing bed.

[0027] Preferably, the bedpan moving mechanism includes a fourth telescopic device hinged to the center frame and a rotating shaft rotatably connected to the center frame. The fourth telescopic device is connected to the rotating shaft through a seventh connecting member. The rotating shaft is connected with a gasket bracket. The gasket bracket is provided with a gasket. The gasket bracket is hinged with an eighth connecting member. The center frame is hinged with a ninth connecting member. The eighth connecting member is hinged to the ninth connecting member. The ninth connecting member is hinged with a bedpan bracket.

[0028] The beneficial effects of adopting the above preferred technical solution are as follows: When the fourth telescopic device extends, through the seventh connecting member, it can drive the rotating shaft and the gasket bracket to rotate forward, so that the gasket bracket drives the gasket to withdraw from the excretion port of the nursing bed. At the same time, when the gasket bracket rotates, through the eighth connecting member, it can drive the ninth connecting member to rotate synchronously, and then drive the bedpan bracket to move from one side of the nursing bed to the excretion port of the nursing bed;

[0029] When the fourth telescopic device retracts, the seventh connecting member can drive the rotating shaft and the gasket bracket to rotate in the reverse direction, so that the gasket bracket drives the gasket to fill the discharge port of the nursing bed. At the same time, when the gasket bracket rotates, the eighth connecting member can drive the ninth connecting member to rotate synchronously, so that the electric bedpan bracket moves from the discharge port of the nursing bed to one side of the nursing bed.

[0065] The head and back follow-up mechanism 8 includes a follow-up plate 801. The first turning plate 401 is longitudinally provided with a plurality of mutually parallel third optical axes 802. In this embodiment, two third optical axes 802 are symmetrically arranged on the left and right sides of the front side and the rear side of the first turning plate 401. The bottom of the follow-up plate 801 is slidably connected to the third optical axes 802 through third linear bearings 803. A first spring 804 is sleeved on the third optical axes 802. The first spring 804 is a compression spring. One end of the first spring 804 is fixedly connected to the front end of the third linear bearing 803, and the other end of the first spring 804 is fixedly connected to the first turning plate 401;

[0066] The head and back follow-up mechanism 8 further includes a traction assembly 805. Two traction assemblies 805 are symmetrically arranged on the left and right sides of the first flip plate 401. The traction assembly 805 includes a second spring 8051 and a traction rope 8052. The second spring 8051 is a tension spring. In this embodiment, the traction rope 8052 is preferably made of steel wire rope. One end of the second spring 8051 is hinged to the bottom of the first flip plate 401 and the other end is rotatably connected to a first pulley 8053. A second pulley 8054 is rotatably connected to the rear side of the first flip plate 401, and a third pulley 8055 is rotatably connected to the front side of the first flip plate 401. The rotation axes of the first pulley 8053 and the second pulley 8054 are both horizontally and transversely arranged, and the rotation axis of the third pulley 8055 is vertically arranged. One end of the traction rope 8052 is connected to the front side of the center frame 3, and the other end of the traction rope 8052 sequentially passes around the first pulley 8053, the second pulley 8054, and the third pulley 8055 and is connected to the follower plate 801. When the first flip plate 401 is parallel to the top surface of the center frame 3, the first spring 804 is in the initial state of elastic deformation or an incompletely compressed state, the second spring 8051 is in a free state, and the third linear bearing 803 is located at the rear end of the third optical axis 802 under the influence of the elastic force of the first spring 804. At this time, the follower plate 801 is in the starting position. When the second telescopic device 601 drives the first flip plate 401 to start rotating, the follower plate 801 applies a pulling force to the second spring 8051 through the traction rope 8052 and causes the second spring 8051 to undergo elastic deformation. During the rotation of the first flip plate 401, the magnitude of the elastic force of the second spring 8051 is always equal to the sum of the elastic force of the first spring 804 and the gravity of the follower plate 801 itself. Therefore, the influence of the elastic force of the first spring 804 and the gravity of the follower plate 801 on the follower plate 801 can be offset by the second spring 8051. The follower plate 801 can move forward along the third optical axis 802 towards the first flip plate 401 with the rotation of the first flip plate 401 due to the frictional force applied by the patient's back;

[0067] There are two anti-falling mechanisms 9 symmetrically arranged on the left and right sides of the center frame 3. The anti-falling mechanism 9 includes a swing frame 901, an anti-falling plate 902, and a fourth connecting member 903. One end of the swing frame 901 is rotatably connected to a second roller 904. The other end of the swing frame 901 is respectively hinged to the rear side of the center frame 3 and one end of the fourth connecting member 903. The other end of the fourth connecting member 903 is hinged to the rear side of the first turning plate 401. The front end of the anti-falling plate 902 is hinged to the front side of the center frame 3. The bottom of the rear end of the anti-falling plate 902 is in rolling connection with the second roller 904. The height of the hinge axis where the fourth connecting member 903 is hinged to the first turning plate 401 is lower than the height of the hinge axis where the first turning plate 401 is hinged to the center frame 3.
