Description

Technical Field

[0001] The utility model relates to the technical field of nursing, and more specifically, to a nursing sit-up frame that can reduce the occupied space area. Background Art

[0002] In order to improve the efficiency and quality of medical services, hospitals will divide departments according to the types of medical services, such as the rehabilitation department, the surgical department, and the internal medicine nursing department. During the treatment process of each department, in order to help patients carry out activity training to improve the rehabilitation rate, a sit-up frame is usually used. For example, in the internal medicine nursing department, in order to assist patients who are bedridden for a long time or have inconvenient mobility to carry out activities in bed to promote the recovery of their physical functions and maintain their daily living abilities, a sit-up frame is often used. However, the sit-up frames in the prior art are usually designed to be integrated with the hospital bed, which causes great inconvenience to the installation and disassembly of the sit-up frame, thus restricting the use range and flexibility of the sit-up frame.

[0003] To solve the above problems, Chinese Patent CN220309318U discloses a sit-up frame for nursing patients with chest tightness and shortness of breath, which includes a base, a groove, an adjustment plate, an adjustment mechanism, a clamping plate, and a telescopic control mechanism. Through the telescopic movement of the telescopic control mechanism, the clamping plate can clamp the nursing sit-up frame on the edge of the bed. Secondly, through the rotation of the output shaft of the motor, the external threaded rod rotates, and at the same time, with the cooperation of the movable rod, the folding of the adjustment plate is realized, so as to realize the function of assisting the patient to sit up. However, during the process of assisting the patient to sit up with the above sit-up frame, since the folding position is fixed, when assisting patients of different heights to sit up, the placement position of the entire sit-up frame needs to be manually adjusted. Otherwise, due to the mismatch between the folding position and the height of the patient, it is very easy to cause discomfort for the patient when sitting up, affecting the comfort of the patient when sitting up.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related art, the present utility model provides a nursing sit-up frame that can reduce the occupied space area to overcome the above technical problems existing in the prior related art.

[0006] Therefore, the specific technical solution adopted by the present utility model is as follows:

[0007] A nursing sit-up frame that can reduce the occupied space area includes a first limiting frame. A first threaded rod is arranged inside the first limiting frame. One end of the first threaded rod is provided with a first motor, and the other end of the first threaded rod is sleeved with a follower block that meshes with it. A fixing block is sleeved outside the end of the first motor. Angle adjustment mechanisms are arranged on one side of the fixing block and the follower block respectively. A telescopic mechanism is arranged between the two angle adjustment mechanisms, and a cushion assembly is arranged at the top of the telescopic mechanism.

[0008] Further, in order to provide more comfortable sitting-up adjustment for patients of different heights, under the combined rotation of the output shafts of Motor Three and Motor Two, the telescopic mechanism can move back and forth along the second limiting frame, thereby adjusting the folding position to meet the sitting-up needs of patients of different heights. Then, under the rotation of the output shaft of Motor Two, the second threaded rod rotates, and under the connection of the connecting rod, the connecting rod makes an arc motion to help the patient above the cushion assembly to sit up. The angle adjustment mechanism includes the second limiting frame arranged on one side of the first limiting frame. Inside the end of the second limiting frame close to the first limiting frame, there is a second threaded rod. A second follower block meshing with it is sleeved outside the second threaded rod. One end of the second threaded rod is provided with Motor Two. Inside the other end of the second limiting frame, there is a third threaded rod. A third follower block meshing with it is sleeved outside the third threaded rod. One end of the third threaded rod is provided with Motor Three. One end of the second follower block is connected to the middle of one side of the telescopic mechanism through a connecting rod. One end of the third follower block is connected to the bottom of one side of the telescopic mechanism through a connecting column.

[0009] Further, in order to compress the space occupation area of the nursing sitting-up frame, under the rotation of the output shaft of Motor One, the first threaded rod is driven to rotate, causing the engaged first follower block to move. Under the combined action of Link One, Link Two and Link Three, a set of storage racks are driven to approach another set of storage racks, so that the nursing sitting-up frame can be folded up when not in use, reducing the space occupation area and facilitating storage and handling. The telescopic mechanism includes the storage racks arranged at the top of the connecting rod. Inside the storage racks, Link One is symmetrically arranged at the center. The middle of Link One is connected to Link Two. One end of Link One is connected to Link Three. Two sets of Link Two and two sets of Link Three are symmetrically arranged inside the storage racks. A rhombus structure is always formed between the two sets of Link One and the two sets of Link Two.

[0010] Further, in order to provide comfortable support for patients, under the action of the cross-connection and communication of several airbags, the cushion assembly can be appropriately deformed according to the body shape of the patient to provide personalized support, thereby ensuring the comfort of the patient during use. In addition, when folding, by discharging the gas in several airbags, the nursing sitting-up frame can be easily folded. The cushion assembly includes the cushion covers arranged at the tops of the two sets of storage racks. Inside the cushion covers, there are several airbags; several airbags are cross-connected and communicated with each other.

[0011] The beneficial effects of the present utility model are:

[0012] 1. Through the cooperative setting of the first limiting frame, the first threaded rod, the first motor, the first follower block, the fixed block, the angle adjustment mechanism, the telescopic mechanism and the cushion assembly, the present utility model can not only perform personalized sitting-up adjustment according to the height of the patient to ensure the comfort of the patient during use, but also can be folded up when not in use, reducing the occupied space and being convenient for storage and handling.

[0013] 2. Through the angle adjustment mechanism, under the combined rotation of the output shafts of the third motor and the second motor, the telescopic mechanism can move back and forth along the second limiting frame, thereby adjusting the folding position to meet the sitting-up needs of patients of different heights. Then, under the rotation of the output shaft of the second motor, the second threaded rod can be rotated, and under the connection action of the connecting rod, the connecting rod can perform an arc motion to help the patient above the cushion assembly to sit up.

[0014] 3. Through the telescopic mechanism, under the rotation of the output shaft of the first motor, the first threaded rod can be driven to rotate, causing the engaged first follower block to move. And under the combined action of the first connecting rod, the second connecting rod and the third connecting rod, a set of storage racks can be driven to approach another set of storage racks, so that the nursing sitting-up frame can be folded up when not in use, reducing the occupied space area and being convenient for storage and handling.

[0025] To further illustrate each embodiment, the present utility model provides accompanying drawings, which are part of the disclosure of the present utility model. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present utility model, a nursing sitting-up frame that can reduce the occupied space area is provided.

[0027] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific embodiments. As Figure 1-7 shown, the nursing sitting-up frame that can reduce the occupied space area according to an embodiment of the present utility model includes a first limit frame 1. A first threaded rod 2 is arranged inside the first limit frame 1. One end of the first threaded rod 2 is provided with a first motor 3, and the other end of the first threaded rod 2 is sleeved with a first follower block 4 that meshes with it; a fixed block 5 is sleeved outside the end of the first motor 3; angle adjustment mechanisms 6 are arranged on one side of both the fixed block 5 and the first follower block 4. A telescopic mechanism 7 is arranged between the two angle adjustment mechanisms 6, and a cushion assembly 8 is arranged at the top of the telescopic mechanism 7.

[0028] With the above technical solution of the present utility model, through the cooperative setting of the first limiting frame 1, the first threaded rod 2, the first motor 3, the first follower block 4, the fixed block 5, the angle adjustment mechanism 6, the telescopic mechanism 7 and the cushion assembly 8, the present utility model can not only perform personalized sitting-up adjustment according to the height of the patient to ensure the comfort of the patient during use, but also can be folded up when not in use, reducing the occupied space and facilitating storage and handling.

[0029] In one embodiment, for the above-mentioned angle adjustment mechanism 6, the angle adjustment mechanism 6 includes a second limiting frame 601 arranged on one side of the first limiting frame 1. Inside the end of the second limiting frame 601 close to the first limiting frame 1, a second threaded rod 602 is arranged. A second follower block 603 meshing with it is sleeved on the outer side of the second threaded rod 602, and a second motor 604 is arranged at one end of the second threaded rod 602; inside the other end of the second limiting frame 601, a third threaded rod 605 is arranged. A third follower block 606 meshing with it is sleeved on the outer side of the third threaded rod 605, and a third motor 607 is arranged at one end of the third threaded rod 605; one end of the second follower block 603 is connected to the middle part of one side of the telescopic mechanism 7 through a connecting rod 608, and one end of the third follower block 606 is connected to the bottom of one side of the telescopic mechanism 7 through a connecting column 609; under the action of the common rotation of the output shafts of the third motor 607 and the second motor 604, the telescopic mechanism 7 can move back and forth along the second limiting frame 601, so as to adjust the folding position to meet the sitting-up needs of patients with different heights. Then, under the rotation action of the output shaft of the second motor 604, the second threaded rod 602 can rotate, and under the connection action of the connecting rod 608, the connecting rod 608 can make an arc motion to help the patient above the cushion assembly 8 to sit up.

[0030] In addition, it should be noted that in order to prevent the first limiting frame 1 from hindering the back-and-forth movement of the telescopic mechanism 7 and causing inconvenience to the adjustment of the folding position, a distance should be left between the first limiting frame 1 and the telescopic mechanism 7 so that there is no obstruction when adjusting the folding position.

[0031] Working principle of the angle adjustment mechanism 6: When the operator places the nursing sitting-up frame on the hospital bed and starts motor three 607 and motor two 604, under the combined rotation of the output shafts of motor three 607 and motor two 604, lead screw two 602 and lead screw three 605 rotate, causing follower block two 603 and follower block three 606 to move the same distance along the second limit frame 601. Under the connection of connecting rod 608 and connecting column 609, the telescopic mechanism 7 can move back and forth along the second limit frame 601, thereby adjusting the folding position to meet the sitting-up needs of patients of different heights. When the patient lies on the nursing frame, by starting motor two 604, lead screw two 602 rotates under the rotation of the output shaft of motor two 604. Under the connection of connecting rod 608, connecting rod 608 makes an arc motion, pushing the telescopic mechanism 7 to make an arc motion around connecting column 609, causing the cushion assembly 8 to fold up at a certain angle to help the patient above the cushion assembly 8 sit up. When the patient needs to lie down, by starting motor two 604, connecting rod 608 makes an arc motion under the reverse rotation of the output shaft of motor two 604, pulling the telescopic mechanism 7 to make an arc motion around connecting column 609 until connecting rod 608 moves to the horizontal position, making the cushion assembly 8 flat, thereby helping the patient lie flat.

[0032] In one embodiment, for the above-mentioned telescopic mechanism 7, the telescopic mechanism 7 includes a storage rack 701 provided at the top of the connecting rod 608. The inner center of the storage rack 701 is symmetrically provided with a first connecting rod 702. The middle of the first connecting rod 702 is connected to a second connecting rod 703, and one end of the first connecting rod 702 is connected to a third connecting rod 704; two groups of second connecting rods 703 and two groups of third connecting rods 704 are symmetrically arranged inside the storage rack 701; two groups of first connecting rods 702 and two groups of second connecting rods 703 always enclose a rhombus structure; under the rotation of the output shaft of motor one 3, lead screw one 2 rotates, causing the engaged follower block one 4 to move. Under the combined action of the first connecting rod 702, the second connecting rod 703 and the third connecting rod 704, one storage rack 701 is driven to approach the other storage rack 701, enabling the nursing sitting-up frame to be folded up when not in use, reducing the occupied space area and facilitating storage and handling.

[0033] Working principle of the telescopic mechanism 7: When the follower block 1 drives a set of storage racks 701 connected thereto to move away from another set of storage racks 701, it simultaneously drives the first link 702 and the third link 704 close to the follower block 1 to perform circular motion. Under the connection action of the second link 703, the first link 702, the second link 703 and the third link 704 cooperate with each other to stretch between the two sets of storage racks 701. When the nursing sit-up frame is not needed, the follower block 1 will drive a set of storage racks 701 connected thereto to move closer to another set of storage racks 701, driving a set of storage racks 701 closer to another set of storage racks 701, so that the first link 702, the second link 703 and the third link 704 cooperate with each other to contract between the two sets of storage racks 701, enabling the nursing sit-up frame to be folded up when not in use, reducing the occupied space area and facilitating storage and handling.

[0034] In one embodiment, for the above-mentioned cushion assembly 8, the cushion assembly 8 includes a cushion cover 801 provided at the top of the two sets of storage racks 701, and a number of air bags 802 are provided inside the cushion cover 801; the number of air bags 802 communicate with each other in a cross manner. Further, in order to provide comfortable support for the patient, under the action of the cross-communication of the number of air bags 802, the cushion assembly 8 can be appropriately deformed according to the body shape of the patient to provide personalized support, thereby ensuring the comfort of the patient during use. In addition, when folding, by discharging the gas in the number of air bags 802, the nursing sit-up frame can be easily folded.

[0035] In addition, it should be noted that in order to prevent the cushion assembly 8 from affecting the contraction of the telescopic mechanism 7, the cushion cover 801 is made of a flexible material, and the number of air bags 802 are provided with inflation holes through which the number of air bags 802 can be inflated and deflated. In addition, the inflation holes are not shown in the figure.

[0036] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0037] In practical applications, when an operator places the nursing sitting-up frame on the hospital bed and starts Motor 1-3, the rotation of the output shaft of Motor 1-3 drives the rotation of the first threaded rod 2, causing the engaged follower block 1-4 to move, driving the stretching of the telescopic mechanism 7, and expanding the nursing sitting-up frame to a width suitable for the patient. Then, the folding position suitable for the patient's height is adjusted through the angle adjustment mechanism 6. After that, the operator inflates the cushion assembly 8. After inflation, the patient lies on the nursing sitting-up frame. When the patient needs to sit up, the angle adjustment mechanism 6 is used to assist the patient to sit up. When the patient does not need to sit up, the angle adjustment mechanism 6 is used to make the patient lie flat. When the patient no longer needs to use it, the operator deflates the cushion assembly 8, and then starts Motor 1-3. Under the reverse rotation of the output shaft of Motor 1-3, the engaged follower block 1-4 moves in the reverse direction, causing the telescopic mechanism 7 to contract, which facilitates the operator to carry out storage.

[0038] In summary, by virtue of the above technical solutions of the present utility model, through the cooperative setting of the first limiting frame 1, the first threaded rod 2, Motor 1-3, the first follower block 4, the fixed block 5, the angle adjustment mechanism 6, the telescopic mechanism 7 and the cushion assembly 8, not only can personalized sitting-up adjustment be carried out according to the patient's height to ensure the comfort of the patient during use, but also it can be folded up when not in use to reduce the occupied space and facilitate storage and handling; through the angle adjustment mechanism 6, under the combined rotation of the output shafts of Motor 3-607 and Motor 2-604, the telescopic mechanism 7 can move back and forth along the second limiting frame 601, thereby adjusting the folding position to meet the sitting-up needs of patients of different heights. Then, under the rotation of the output shaft of Motor 2-604, the second threaded rod 602 rotates, and under the connection action of the connecting rod 608, the connecting rod 608 makes an arc motion to help the patient above the cushion assembly 8 to sit up; through the telescopic mechanism 7, under the rotation of the output shaft of Motor 1-3, the first threaded rod 2 rotates, causing the engaged follower block 1-4 to move, and under the cooperative action of the first connecting rod 702, the second connecting rod 703 and the third connecting rod 704, a set of storage racks 701 are driven to approach another set of storage racks 701, enabling the nursing sitting-up frame to be folded up when not in use, reducing the occupied space area and facilitating storage and handling.
