Description

Technical Field

[0001] The present invention relates to a medical nursing bed mechanism, in particular to a supporting mechanism of a nursing bed suitable for patients to sit on. Background Art

[0002] With the development of society, medical nursing beds are becoming more and more advanced, and various forms of medical beds are emerging one after another, which greatly facilitates the postoperative recovery of patients. However, among the existing various types of postoperative rehabilitation nursing beds, there is a common problem that they are not suitable for patients to sit and rest. Generally, during the postoperative recovery stage, patients cannot always lie flat on the bed, and often need to sit on a bed supported at one end to rest or eat. However, in the nursing beds that can be supported at one end, all that is supported is half of the flat bed board near the head. Such a flat bed board is extremely uncomfortable for patients to sit on. Figure 1 As shown, if the bed board 6 is raised at a certain angle, the simulated patient 12 cannot sit on the bed board 6 because the buttocks are restricted by the bed board at the bed board rotation axis 9. It is inconvenient to eat or sit and rest when leaning against the bed board. In addition, the buttocks will slip on the horizontal bed board 10 and it will be difficult to sit. If you insist on sitting for a while, you will feel very tired and the mattress on the bed board will be pushed forward, making the items on the bed messy. If the bed board 6 is raised vertically, the simulated patient 12 can only sit upright at right angles to the horizontal bed board 10, and the bed board 6 loses its function of leaning against. That is, the existing nursing beds that can be raised at one end do not conform to the human-machine relationship and the relationship between man and environment in ergonomics, which has a great adverse effect on the patient's recovery and also brings unfavorable factors to the hospital ward management. Summary of the Invention

[0003] The purpose of the present invention is to overcome the common shortcomings of the nursing beds supported at one end in the background technology. According to the principles of ergonomics, a new bed supporting mechanism suitable for patients to sit on is provided. This supporting mechanism can be installed on all nursing beds. The bed board surface of the supporting bed is made into an ergonomic curved shape suitable for patients to sit on, so that patients can sit and rest, providing favorable support for the patient's early recovery.

[0004] The present invention is a bed support mechanism suitable for patients to sit Figure 2 As shown, it includes a power rod 1, an active rod 2, a bed side 19, a horizontal edge 3, a thrust rod 4, a second rotating shaft 7, a fixed rotating shaft 8, a bed board rotating shaft 9, a horizontal bed board 10, slats 11, an inclined bed board 13, a curved support rod 14, and a first rotating shaft 15.

[0005] The bed board of the bed support mechanism is divided into a horizontal bed board 10 and an inclined bed board 13. The horizontal bed board 10 is connected to the inclined bed board 13 through a bed board rotating shaft 9. The horizontal bed board 10 and the inclined bed board 13 are placed within the horizontal edge 3 of the bedside 19 on both sides of the bed. The inclined bed board 13 can rotate upward around the bed board rotating shaft 9.

[0006] The rear end of the power rod 1 is connected to the lower end of the active rod 2 through the first rotating shaft 15. The active rod 2 is fixedly connected to the thrust rod 4. The fixed rotating shaft 8 passes through the fixed connection point between the active rod 2 and the thrust rod 4, and the active rod 2 and the thrust rod 4 can rotate around the fixed rotating shaft 8.

[0007] The upper end of the thrust rod 4 is fixedly connected to the middle portion of the curved support rod 14 via the second rotating shaft 7, and the thrust rod 4 can rotate around the second rotating shaft 7;

[0008] The curved support rod 14 is a long metal rod with a rectangular cross section. Figure 4 As shown, the curved support rod 14 is formed into a curved shape suitable for a human body to sit on on the surface contacting the inclined bed board 13.

[0009] Furthermore, the fixed shaft 8 is fixedly mounted on the bed of the nursing bed.

[0010] The inclined bed plate 13 is made of a plate with relatively high strength. Figure 3 As shown, the inclined bed board 13 is formed by connecting the slats 11 to each other within the height range of the contact with the human waist. In the bed board area formed by the connection of the slats 11, the board surface of the inclined bed board 13 can bend along the height direction;

[0011] The inclined bed plate 13 forms three areas when the human body is sitting, the lower plane 16 below the waist, the waist contact surface is the curved surface 17, and the upper plane 18 above the waist contact surface.

[0012] Furthermore, the contact surface between the lower surface of the inclined bed board 13 and the curved support rod 14 is a smooth hard surface, and the curved support rod 14 can slide on the lower surface of the inclined bed board 13 .

[0013] Furthermore, when the curved support rod 14 contacts the lower surface of the inclined bed board 13 and lifts the inclined bed board 13 upward, the upper surface of the curved support rod 14 rotates forward and downward along the lower surface of the inclined bed board 13 until the bendable part of the inclined bed board 13 fits the curved shape of the curved support rod 14, so that the surface of the inclined bed board 13 forms a curved shape suitable for the human body to sit on. When the human body sits on the inclined bed board 13 with its back, the lower side of the waist fits with the lower plane 16 of the inclined bed board 13, and the waist leans backward on part of the curved surface 17 of the inclined bed board 13, and the surface of the upper plane 18 of the inclined bed board 13 is tilted forward.

[0014] When the curved support rod 14 moves backward along the lower surface of the inclined bed board 13, the inclined bed board 13 gradually flattens downward until the lower plane 16, curved surface 17 and upper plane 18 of the inclined bed board 13 fall into the horizontal edges 3 of the bedside 19 on both sides of the bed, and the inclined bed board 13 and the horizontal bed board 10 are in the same horizontal plane.

[0015] Compared with the prior art, the present invention has the following beneficial effects: it completely overcomes the problem that the patient cannot sit on the nursing bed supported at one end in the prior art; when the curved support rod 14 contacts the lower surface of the inclined bed board 13 and supports the inclined bed board 13 upward, the bendable portion of the inclined bed board 13 fits with the curved shape of the curved support rod 14, so that the surface of the inclined bed board 13 forms a curved surface shape suitable for the human body to sit on; when the human body sits on the inclined bed board 13 with its back, the lower side of the waist fits with the lower plane 16 of the inclined bed board 13, and the waist leans backward on the curved surface 17 of the inclined bed board 13 On part of the board surface, the upper plane 18 of the inclined bed board 13 is in a forward-leaning shape. When the patient sits on the curved surface of the inclined bed board 13, the curved surface shape of the inclined bed board 13 fully conforms to the human-machine relationship and the relationship between man and environment in ergonomics. It can not only meet the patient's needs of sitting to rest and sitting to eat, but also has a great positive impact on the patient's recovery. It can also avoid the patient slipping and getting unable to sit on the horizontal bed board 10, and pushing the mattress on the bed board forward, making the items on the bed become messy, and also creates good conditions for the standardized management of hospital wards. The device has a simple structure, is easy and quick to manufacture, has low cost, and is easy to operate. It can not only conveniently produce a new type of bed suitable for patients to sit on, but also can transform and upgrade the existing related nursing beds, with significant economic benefits.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] The present invention is a bed support mechanism suitable for patients to sit on, and its preferred embodiment is as follows: Figure 2 shown.

[0024] The present invention provides a bed support mechanism suitable for patients to sit on, comprising a power rod 1, an active rod 2, a bedside 19, a horizontal edge 3, a thrust rod 4, a second rotating shaft 7, a fixed rotating shaft 8, a bed board rotating shaft 9, a horizontal bed board 10, slats 11, an inclined bed board 13, a curved support rod 14, and a first rotating shaft 15.

[0025] The support mechanism of a hospital bed suitable for patients to sit on can be used as a part of a nursing and rehabilitation bed, and its power comes from a power rod 1. The rear end of the power rod 1 is connected to the lower end of the active rod 2 through a first rotating shaft 15. The active rod 2 is fixedly connected to the thrust rod 4. The fixed rotating shaft 8 passes through the fixed connection point between the active rod 2 and the thrust rod 4, and the active rod 2 and the thrust rod 4 can rotate around the fixed rotating shaft 8; the upper end of the thrust rod 4 is fixedly connected to the middle part of the curved support rod 14 through a second rotating shaft 7, and the thrust rod 4 can rotate around the second rotating shaft 7. In this way, when the power rod 1 moves forward (left end of the bed) or backward (right end of the bed) under the main power of the nursing bed, the active rod 2 and the thrust rod 4 form a lever with the fixed rotating shaft 8 as the fulcrum, so that the second rotating shaft 7 connected to the thrust rod 4 rotates counterclockwise around the fixed rotating shaft 8, and the inclined bed board 13 can be raised or lowered.

[0026] The bed supporting mechanism includes the bed board of the bed, and the bed board is divided into a horizontal bed board 10 and an inclined bed board 13. The horizontal bed board 10 is connected to the inclined bed board 13 through the bed board rotating shaft 9. Generally, the horizontal bed board 10 and the inclined bed board 13 are horizontally placed within the horizontal edge 3 of the bedside 19 on both sides of the bed. When the inclined bed board 13 needs to be supported, the inclined bed board 13 can be rotated upward around the bed board rotating shaft 9.

[0027] In order to raise or lower the inclined bed board 13, the upper end of the thrust rod 4 is fixedly connected to the middle part of the curved support rod 14 through the second rotating shaft 7, and the curved support rod 14 is in contact with the inclined bed board 13. The curved support rod 14 is a long metal rod with a rectangular cross-section. The surface of the curved support rod 14 in contact with the inclined bed board 13 is made into a curved shape suitable for human body sitting.

[0028] In this embodiment, the inclined bed plate 13 is made of a relatively high strength plate, such as Figure 3 As shown, deformation or vibration is not allowed when it is propped up. The inclined bed board 13 is made of slats 11 connected to each other within the height range of contact with the human waist. Within the bed board interval formed by the connection of the slats 11, the board surface of the inclined bed board 13 can bend along the height direction. In this way, the inclined bed board 13 forms three areas when the human body is leaning against it, the lower plane 16 below the waist, the waist contact surface is the curved surface 17, and the upper plane 18 above the waist contact surface.

[0029] In order to be able to smoothly raise or lower the inclined bed board 13, the contact surface between the lower surface of the inclined bed board 13 and the curved support rod 14 needs to have a certain contact pressure. Therefore, the contact surface between the inclined bed board 13 and the curved support rod 14 is required to be a smooth and hard surface. If necessary, the contact surface between the inclined bed board 13 and the curved support rod 14 can also be made into a track, and a medium is used to lubricate the surface where the curved support rod 14 and the inclined bed board 13 contact each other to ensure that the curved support rod 14 slides on the surface where the curved support rod 14 and the inclined bed board 13 contact each other.

[0030] When the curved support rod 14 contacts the lower surface of the inclined bed board 13 and supports the inclined bed board 13 upward, the upper surface of the curved support rod 14 moves forward and downward along the lower surface of the inclined bed board 13 until the bendable part of the inclined bed board 13 fits with the curved shape of the curved support rod 14, so that the surface of the inclined bed board 13 forms a curved shape suitable for the human body to sit on. When the human body sits on the inclined bed board 13 with its back, the lower side of the waist fits with the lower plane 16 of the inclined bed board 13, and the waist leans backward on part of the curved surface 17 of the inclined bed board 13. The surface of the upper plane 18 of the inclined bed board 13 is tilted forward.

[0031] When the curved support rod 14 moves backward along the lower surface of the inclined bed board 13, the inclined bed board 13 gradually flattens downward until the lower plane 16, curved surface 17 and upper plane 18 of the inclined bed board 13 fall into the horizontal edges 3 of the bedside 19 on both sides of the bed, and the inclined bed board 13 and the horizontal bed board 10 are in the same horizontal plane.

[0032] Compared with the prior art, a bed support mechanism suitable for patients to sit on completely overcomes the problem that patients cannot sit on the nursing beds supported at one end in the prior art. When the inclined bed board 13 is supported upward, the bendable portion of the inclined bed board 13 fits in with the curved shape of the curved support rod 14, so that the surface of the inclined bed board 13 forms a curved surface shape suitable for the human body to sit on. When the patient needs to sit to rest or eat, the patient sits on the inclined bed board 13 with his back. At this time, the lower side of the patient's waist fits in with the lower plane 16 of the inclined bed board 13, and the waist leans backward on the part of the curved surface 17 of the inclined bed board 13. The upper plane 18 of the inclined bed board 13 is in a forward-leaning shape. When the patient sits on the curved surface of the inclined bed board 13, the curved surface shape of the inclined bed board 13 fully conforms to the human-machine relationship and the relationship between man and environment in ergonomics. It can not only meet the patient's needs for sitting to rest and sitting to eat, but also has a great positive impact on the patient's rehabilitation, bringing good news to the majority of rehabilitation patients. It can also avoid the patient slipping and getting stuck on the horizontal bed board 10, and pushing the mattress on the bed board forward, making the items on the bed become messy, and also creates good conditions for the standardized management of hospital wards. The device has a simple structure, is easy and quick to manufacture, has low cost, and is easy to operate. It can not only conveniently produce a new type of bed suitable for patients to sit on, but also can transform and upgrade existing related nursing beds, with significant economic benefits.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the scope of protection of the present invention.
