Description

Technical Field

[0001] The invention relates to nursing equipment, in particular to a nursing bed. Background Art

[0002] Patients who are bedridden for a long time face the problem of continuous pressure on local limbs. If the limbs are subjected to long-term pressure and tissue hypoxia occurs, bedsores will occur. Therefore, patients who are bedridden for a long time need to turn over and move their bodies frequently. Currently, the common anti-bedsore mattresses have the function of assisting patients to turn over, but they still cannot alleviate the problem of blood circulation problems caused by long-term pressure on patients. Patients still face a greater risk of tissue necrosis.

[0003] Therefore, there are multifunctional nursing beds on the market that can achieve multiple functions, including raising the back, turning over, bending the legs and other movements, and laying air cushions on the surface of the bed can also achieve the purpose of preventing bedsores. Although this nursing function is good, the anti-bedsore effect is obviously not good, the air cushion is easy to deviate and has a short lifespan. Summary of the invention

[0036] The technical solution of the present invention is further described below through the accompanying drawings and specific embodiments.

[0037] refer to Figure 1-Figure 13 A multifunctional anti-bedsore nursing bed comprises a bed board assembly 11, an anti-bedsore assembly 12, a nursing assembly 13, a resetting assembly 14 and a base 2.

[0038] The bed board assembly 11 includes a first support bar group 111, a second support bar group 112 and a support board 110; a plurality of support bars 1111 included in the first support bar group 111 and a plurality of support bars 1121 included in the second support bar group 112 are staggered along the length direction of the support board 110 on the side of the support board 110 facing the human body;

[0039] And the support plate 110 is divided into at least two areas which are hingedly connected.

[0040] The anti-bedsore component 12 is used to drive the first support bar group 111 and the second support bar group 112 to be lifted alternately; the care component 13 is used to lift at least one area of ​​the support plate 110 and the support bars 1111 and 1121 arranged in the area are also lifted accordingly to lift part of the user's body.

[0041] When the first support bar group 111 and the second support bar group 112 are alternately lifted, the reset component 14 accumulates elastic reset force, and the positioning block 141 in the reset component 14 moves along with the support bars 1111 and 1121 in a direction away from the positioning groove 142; when the support bars 1111 and 1121 are lowered, the reset component 14 releases the elastic reset force to drive the positioning block 141 to fall back into the positioning groove 142.

[0042] In the above-mentioned anti-bedsore nursing bed, when the support bars 1111 and 1121 need to be returned to their original positions, the support bars 11 and 21 can be accurately placed in their original positions under the action of the reset assembly 14. The reset assembly 14 can prevent the support bars 1111 and 1121 from overlapping each other, thereby causing harm to the rehabilitation personnel. Therefore, the nursing function and the anti-bedsore function are simultaneously provided on one nursing bed.

[0043] In this embodiment, the positioning groove 142 is arranged on the side of the support plate 110 facing the support bars 1111, 1121, and the positioning block 141 is arranged on the side of the support bar facing the support plate 110. The positioning groove 142 is formed by slotting the support plate 110, and it has a bottom, which can limit the lowest descending function of the support bars 1111, 1121, and also has a supporting function. The reset assembly 14 also includes a first connecting rod 143 and a second connecting rod 144 of the support plate 110 hinged at one end, and a torsion spring 145 that brings the first connecting rod 143 and the second connecting rod 144 closer to each other. The other end of the first connecting rod 144 is hinged to the support bars 1111, 1121, and the other end of the second connecting rod 144 is hinged to the support plate 110.

[0044] In this way, when the support bars 1111 and 1121 are lifted, the first connecting rod 143 and the second connecting rod 144 move away from each other, and the torsion spring 145 accumulates elastic restoring force. When the support bars 1111 and 1121 are reset, the torsion spring 145 releases the elastic restoring force to drive the first connecting rod 143 and the second connecting rod 144 to move closer to each other, and at the same time drive the positioning block 1141 to fall back into the positioning groove 1142.

[0045] The anti-bedsore component 12 can sample a variety of structures, such as the structures recorded in the applicant's four prior applications: 2020206356025, 202021089549X, 2020210904785, and 202021090829.2. Here, 202021090829.2 is taken as an example to introduce the anti-bedsore structure of this embodiment.

[0046] Specifically in this embodiment, the anti-bedsore component 12 includes a connecting component and a driving component;

[0047] The connection assembly includes a first connection assembly 121 and a second connection assembly 122, and the driving assembly is used to drive the first connection assembly 121 and the second connection assembly 122 to rise alternately. The first connection assembly includes a plurality of synchronously linked first connection members 1212, and each support bar 1111 in the first support bar group 111 has a first connection member 1212 corresponding thereto, and the first connection member 1212 is used to abut the corresponding support bar 1111. Each support bar 1121 in the second support bar group 112 has a second connection member 1222 corresponding thereto, and the second connection member 1222 is used to abut the corresponding support bar 1121.

[0048] It should be noted that there is no connection between the first connecting member 1212, the second connecting member 1222 and the support bars 1111, 1121, but the first connecting member 1212, the second connecting member 1222 abuts against the support bars 1111, 1121 during the rising process, thereby driving the support bars 1111, 1121 to rise.

[0049] In the first support bar group 111, both ends of each support bar 1111 along the width direction of the nursing bed correspond to the first connecting piece 1212; in the second support bar group 112, both ends of each support bar 1121 along the width direction of the nursing bed correspond to the second connecting piece 1222. By including at least two connecting pieces 1212, 1222 at both ends to support one support bar 1111, 1121, the stability and reliability of the movement of the support bars 1111, 1121 are ensured.

[0050] The driving assembly includes a translation assembly and a reversing assembly. The translation assembly includes a first translation member 123 and a second translation member, and the reversing assembly includes a first reversing member and a second reversing member. The first translation member 123 is connected to the first connecting member 121 through the first reversing member; and the second translation member is connected to the second connecting member 122 through the second reversing member.

[0051] The first reversing assembly changes the reciprocating movement of the first translation member 123 along the length direction of the support plate 110 into the reciprocating movement of the first connecting assembly 121 along the thickness direction of the support plate 110 , thereby driving the first support bar group 111 to reciprocate along the thickness direction of the support plate 110 .

[0052] The second reversing assembly switches the reciprocating movement of the second translation member along the length direction of the support plate 110 into the reciprocating movement of the second connecting assembly 122 along the thickness direction of the support plate 110 , thereby driving the second support bar group 112 to reciprocate along the thickness direction of the support plate 110 .

[0053] The anti-bedsore nursing bed provided by the present invention converts the reciprocating translation of the translation assembly in the horizontal direction into the reciprocating lifting and lowering of the first connecting assembly 121 and the second connecting assembly 122 in the vertical direction through the reversing assembly, and drives the first reversing assembly and the second reversing assembly respectively through the first translation member 123 and the second translation member. The first support bar group 111 and the second support bar group 112 can be made to move asynchronously through the asynchronous movement of the first translation member 123 and the second translation member or through the different reversing structures of the first reversing assembly and the second reversing assembly, thereby causing the board surface of the bed board assembly 11 to rise and fall.

[0054] The ups and downs of the bed board assembly can help patients activate their bodies and reduce tissue hypoxia. In addition, the translation-vertical reversing assembly has a simple structure, is easy to implement, and has a relatively low cost.

[0055] In one embodiment of the present invention, the first reversing assembly includes a first slide groove 1231 disposed on the first translation member 123 and a first roller (not marked) disposed on the first connecting assembly 121; the first slide groove 1231 has two parts with different heights; when the first roller moves along the first slide groove 1231 between the two parts with different heights, it drives the first connecting assembly 121 to rise or fall;

[0056] The second reversing assembly includes a second slide groove arranged on the second translation member and a second roller (not marked) arranged on the second connecting assembly 122; the second slide groove has two parts with different heights; when the second roller moves along the second slide groove between the two parts with different heights, it drives the second connecting assembly 122 to rise or fall.

[0057] In order to realize asynchronous lifting and lowering of the first connecting component 121 and the second connecting component 122, the first sliding groove 1231 and the second sliding groove are arranged in opposite directions.

[0058] In one embodiment of the present invention, the translation directions of the first translation member 123 and the second translation member are parallel to each other. In this embodiment, the first slide 1231 and the second slide have the same shape but are arranged in opposite directions, including a first straight portion 12311 and a second straight portion 12312 extending along the translation direction of the first translation member 123; the first straight portion 12311 and the second straight portion 12312 have different heights, and the first straight portion 12311 and the second straight portion 12312 are connected by an inclined portion 12313. The slopes of the inclined portions 12313 of the first slide 1231 and the second slide are opposite.

[0059] When the roller of the first connecting component 121 is located at the first straight portion 12311 in the first slide slot 1231, the roller of the second connecting component 122 is located at the second straight portion 12312 in the second slide slot, and the second support bar group 112 is raised. Conversely, when the roller of the first connecting component 121 is located at the second straight portion 12312, the roller of the second connecting component 122 is located at the first straight portion 12311, and the first support bar group 111 is raised. In addition, the horizontal length of the first straight portion 12311 is equal to the sum of the horizontal lengths of the second straight portion 12312 and the inclined portion 12313, so that when the roller of the first connecting component 121 moves along the first straight portion 12311 to the connection point between the first straight portion 12311 and the inclined portion 12313, the roller of the second connecting component 122 also moves along the second straight portion 12312 and the inclined portion 12313 to the connection point between the inclined portion 12313 and the first straight portion 12311. At this time, the heights of the first support bar group 111 and the second support bar group 112 are the same, and the board surface of the entire bed board assembly 11 is in a horizontal state.

[0060] On the basis of the above structure, the positions where the first chute 1231 and the second chute have different heights can be divided into several gears, so that the bed surface can change between the heights of different gears, which is convenient for users to choose. In this embodiment, the first chute 1231 and the second chute are not set with gears, but setting the gears as needed is a simple replacement of this embodiment. If you want to achieve gear control, you only need to add a few inclined planes, and connect the inclined planes with straight parts.

[0061] In one embodiment of the present invention, the first slide groove 1231 and the second slide groove are respectively arranged on the first translation member 123 and the second translation member in a direction parallel to the length of the support plate 110. The first roller and the second roller are respectively arranged on the first connection component 121 and the first connection component 122 in a direction parallel to the length of the support plate.

[0062] In this embodiment, the first connecting component 121 includes a connecting bar 1211, and the second connecting component 122 includes a connecting bar 1221; the connecting bars 1211 and 1221 are arranged on the side of the support plate 110 facing away from the human body, all the first connecting members 1212 are fixed to the connecting bar 1211 so that all the first connecting members 1212 are synchronously linked, and all the second connecting members 1222 are fixed to the connecting bar 1221 so that all the second connecting members 1222 are synchronously linked; the support plate 110 is provided with a clearance hole along the thickness direction; the first connecting member 1212 and the second connecting member 1222 pass through the clearance hole and are located below the support bars 1111 and 1112.

[0063] In this way, when the first connecting member 1212 and the second connecting member 1222 are lifted, they will press against the supporting bars 1111 and 1112, thereby lifting the supporting bars 1111 and 1112 that press against them. There is a gap between the first connecting member 1212 and the second connecting member 1222 and the clearance hole, so that the first connecting member 1212 and the second connecting member 1222 will not rub against the clearance hole during the lifting process, resulting in an unsmooth lifting.

[0064] In order to ensure that the first translation member 123 and the second translation member can move accurately along a predetermined direction and thus prevent the roller from falling out of the slide groove 6, the anti-bedsore assembly also includes a support plate 110 having a guide rail 124, and the guide rail 124 is fixed to a fixed seat (not marked); the first translation member 123 is slidably connected to the guide rail 124.

[0065] In one embodiment of the present invention, the first translation member 123 and the second translation member are driven by the lead screw 125 respectively; the first translation member 123 and the second translation member are respectively provided with a lead screw nut matched with the lead screw 125; when the lead screw 125 rotates, the first translation member 123 and the second translation member translate along the length direction of the support plate 110;

[0066] In addition, in order to allow the two groups of first connecting components 121 and the two groups of second connecting components 122 to move synchronously, the anti-bedsore component 12 also includes a driving motor 126, each screw rod 125 is rotatably connected to a pulley 127, and all the pulleys 127 are connected to the output shaft of the driving motor 126 through a belt 128.

[0067] In this way, through the transmission of the driving motor 126 and the belt 128, all the screw rods 125 can be rotated synchronously, and the synchronous rotation of the screw rods 125 will drive all the translation parts to move synchronously.

[0068] In this embodiment, a reversing mechanism connected to the first connecting assembly 121 and a reversing mechanism connected to the second connecting assembly 122 are provided at each end of the support plate 110 in the length direction. By supporting the first connecting assembly 121 and the second connecting assembly 122 at both ends, the movement of the connecting assembly is more stable.

[0069] In this embodiment, the support plate 13 includes at least a neck and back region 113, a waist and hip region 114, a thigh region 115 and a calf region 116 which are hinged in sequence along the length direction of the nursing bed. The nursing assembly includes a back-lifting mechanism 131 and a leg-bending mechanism 132, and a fixed frame 130 carrying the back-lifting mechanism 131 and the leg-bending mechanism 132. The back-lifting mechanism 131 is located below the neck and back region 113, and includes a first driving member 1311, a first connecting rod 1312, a first rotating shaft 1313, and a back-lifting support rod 1314; the first driving member 1311 is installed on the fixed frame 130, the first driving member 1311 is connected to the first rotating shaft 1313 through the first connecting rod 1312, the first rotating shaft 1313 is rotatably installed on the fixed frame 130, one end of the back-lifting support rod 1314 is fixedly connected to the first rotating shaft 1313, and the other end is a free end. The first driving member 1311 drives the first rotating shaft 1313 to rotate through the first connecting rod 1312, thereby driving the back-lifting support rod 1314 to rotate upward. During the rotation process, the free end of the back-lifting support rod 1314 abuts against the neck and back area 113, thereby driving the neck and back area 113 to rotate around the hinge position to achieve the back-lifting function. The leg-bending mechanism 132 is located below the thigh area 115, and includes a second driving member 1321, a second connecting rod 1322, a second rotating shaft 1323, and a leg-bending support rod 1324; the second driving member 1321 is installed on the fixing frame 130, and the second driving member 1321 is connected to the second rotating shaft 1323 through the second connecting rod 1322, and the second rotating shaft 1323 is rotatably installed on the fixing frame 130, and one end of the leg-bending support rod 1324 is fixedly connected to the second rotating shaft 1323, and the other end is a free end. The second driving member 1321 drives the second rotating shaft 1323 to rotate through the second connecting rod 1322, thereby driving the leg bending support rod 1324 to rotate upward. During the rotation process, the free end of the leg bending support rod 1324 abuts against the thigh area 115, thereby driving the thigh area 115 to rotate around the hinge position to achieve the leg bending function.

[0070] The neck and back area 113, waist and hip area 114, thigh area 115 and calf area 116 are divided into three mutually hinged left, middle and right sections along the width direction of the nursing bed, and the three sections are hinged by hinge pins along the length direction of the nursing bed; when turning over, the three sections of the back area 113 are lifted synchronously; when bending the legs, the three sections of the thigh area 115 and the calf area 116 are lifted synchronously.

[0071] The left section of the neck and back area 113, the left section of the waist and hip area 114, the left section of the thigh area 115 and the left section of the calf area 116 are hinged together by a hinge pin along the width direction of the nursing bed to form a left area 117; the middle section of the neck and back area 113, the middle section of the waist and hip area 114, the middle section of the thigh area 115 and the middle section of the calf area 116 are hinged together by a hinge pin along the width direction of the nursing bed to form a middle area 118; the right section of the neck and back area 113, the right section of the waist and hip area 114, the right section of the thigh area 115 and the right section of the calf area 116 are hinged together by a hinge pin along the width direction of the nursing bed to form a right area 119. Due to the presence of the hinge pin, when turning over, the left area 117, the middle area 118 and the right area 119 can be flipped synchronously.

[0072] The nursing component 13 also includes a rollover mechanism 133, which is located below the waist and hip area 114 and is used to lift the left middle area 117, 118 or the right middle area 118, 119. The nursing bed is divided into three areas along the direction of the nursing bed. The user lies in the middle area 118 to turn over, which avoids the risk of the user's back being pinched. At the same time, it is safer and avoids rolling down due to turning over. The back lifting mechanism 131, the leg bending mechanism 132, and the rollover mechanism 133 are respectively arranged at different positions, which is conducive to avoiding interference between multiple mechanisms.

[0073] like Fig.12 As shown, the rollover mechanism 133 includes two third driving members 1331 arranged crosswise. The two third driving members 1331 are installed on a fixed seat (not marked), and the movable ends of the two third driving members 1331 are respectively hinged to the bottom surface of the middle area 118, and are located at both ends of the middle area 118 along the width direction of the nursing bed. Driven by the third driving member 1331 on the left or right side, the left or right side of the middle area 118 is lifted, and the left area 117 or the right area 119 is lifted with the middle area 118. In this embodiment, the fixed frame 130 is fixedly connected to the support plate 110 where the middle area 118 is located, so the movable ends of the two third driving members 1331 are respectively hinged to the bottom surface of the fixed frame 130, directly driving the fixed frame 130 to lift.

[0074] In a preferred embodiment, the hinge points of the left area 117 and the middle area 118, the hinge points of the right area 119 and the middle area 118, and the hinge points of the thigh area 115 and the calf area 116 are all provided with limiting devices, such as limit blocks, etc., which will not be further described here. When the left middle areas 117 and 118 are lifted, the left area 117 is horizontal; when the right middle areas 118 and 119 are lifted, the right area 119 is horizontal; when the legs are bent, the thigh area 115 is inclined and the calf area 116 is horizontal.

[0075] The first driving member 1311 , the second driving member 1321 , and the third driving member 1331 are preferably electric cylinders.

[0076] The nursing component 13 also includes two sets of support frames 1300, which correspond to the left side of the left area 117 and the right side of the right area 119, respectively, and are used to support the bed board component 11. At the same time, when turning over to the left or right, the support frames 1300 limit and support the right area 119 or the left area 117 to prevent the user from turning over, which is safer. The support frames 1300 are equipped with rollers to reduce the friction between them and the right area 119 or the left area 117.

[0077] Finally, the base 2 is connected to the anti-bedsore component 12 through two lifting columns 21; the base 2 is provided with a height-adjustable support foot 22 and a sliding wheel 24 on the side facing the bottom surface; a storage space is also provided in the base 2, and a baffle 23 for opening or closing the storage space is provided on the side wall of the base 2.

[0078] Because the bed board assembly 11 and the nursing assembly 13 are connected to the top of the anti-bedsore assembly 12, the overall height of the nursing bed can be adjusted by the lifting column 21. The sliding wheel 24 facilitates the displacement of the nursing bed; the horizontality of the nursing bed can be adjusted by the height-adjustable support legs 22. At the same time, when the nursing bed is displaced, the support legs 22 are retracted to avoid affecting the displacement of the nursing bed. After the nursing bed is fixed in position, the support legs 22 touch the ground to play a fixed support role. The storage space can facilitate users to store commonly used daily necessities or medicines.

[0079] It should be noted that the support plate 110 in this embodiment mainly comprises a frame assembled from several profiles, and a flat plate is installed on the side of the frame facing away from the use. The support plate 110 can be formed by hingedly connecting several frames with flat plates installed as needed, for example, the left section of the neck and back area 113, the left section of the waist and hip area 114, the left section of the thigh area 115, the left section of the calf area 116, the middle section of the neck and back area 113, the middle section of the waist and hip area 114, the middle section of the thigh area 115, the middle section of the calf area 116, the right section of the neck and back area 113, the right section of the waist and hip area 114, the right section of the thigh area 115, and the right section of the calf area 116 are each a frame with a flat plate installed, and two adjacent frames are hinged. The third driving member 1331 can be arranged at the anti-bedsore component 12 or below it, and the movable rod of the third driving member 1331 extends upward from the gap of the anti-bedsore component 12 and is hinged with the middle area 118 or the fixing frame 130.

[0080] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
