Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular to a device for turning over a critical care patient that can be operated by a single person. Background Art
[0002] After timely and effective treatment, critically ill patients need to be sent to the intensive care unit for care. Since critically ill patients need to stay in bed for a long time, their local skin is under pressure or rubbed against sheets and clothes, which can easily cause damage and further develop pressure sores. Generally, regular turning over can prevent this. However, due to the poor limb coordination ability of patients during critical illness, nursing staff are required to manually position the patient and assist the patient in turning over. The technical problems existing in the existing turning over operation are as follows: the patient's knee joint needs to be in a bent and curled state after turning over to protect the lateral stability after turning over. Therefore, the nursing staff needs to pre-position the knee joint to the required bending shape after turning over before turning over. At this time, the patient's body pressure is concentrated on the thigh position, and the nursing staff needs to apply a large thrust. Therefore, when a single nursing staff handles it, it is impossible to fix the patient's head. When turning over, it is not easy for the head to turn over synchronously with the waist and legs, and the flexibility when turning over is poor. In order to solve this technical problem, we propose a critical care patient turning device that can be operated by one person. Summary of the invention
[0003] The main purpose of the present invention is to provide a critical care patient turning device which can be operated by a single person.
[0004] To achieve the above object, the technical solution adopted by the present invention is:
[0005] A device for turning over critical care patients that can be operated by a single person comprises a turning bed frame, wherein a turning mechanical drive execution module and a foot middle section positioning module are installed at the upper end of the turning bed frame, one side of the turning mechanical drive execution module is fixedly connected to a tail end vertical limiting module via a mechanical arm driving unit, one side of the tail end vertical limiting module is hingedly installed with a front foot end fixed support via a turning path limiting module, a turning knee raising adjustment module for adjusting the turning inclination is installed between the turning path limiting module and the front foot end fixed support, and the tail end vertical limiting module is also installed with a turning completion detection module for detecting the turning completion of the foot middle section positioning module.
[0006] A further improvement of the present invention is that the turning path limiting module includes a rotation locking module and a contact point adjustment module, the contact point adjustment module is used to adjust the support contact surface according to the flexion and extension state of the patient's legs, and the rotation locking module is used for limiting the position after the contact point adjustment module adjusts the support contact surface.
[0007] A further improvement of the present invention is that the turning over and knee lifting adjustment module includes a knee buckle module and a restraint module, the restraint module is fixed to the outside of the tail end vertical limiting module, and one end of the restraint module is snap-connected to the knee buckle module through a snap shell.
[0008] A further improvement of the present invention is that the tail end vertical limiting module is composed of an external fixing ring, a knee support buffer layer and an air cushion buffer module, and the knee support buffer layer and the air cushion buffer module are both fixedly connected to the inner side of the external fixing ring to support the patient's knees after they are raised when turning over.
[0009] A further improvement of the present invention is that the turning completion detection module includes a post-turning contact sensing unit, a turning time recording unit, a data processor and a wireless signal uploading unit. After the middle section of the foot positioning module drives the patient's legs to contact the turning completion detection module during the auxiliary turning action, the contact signal is sensed by the post-turning contact sensing unit, and the time required to complete the turning action is counted by the turning time recording unit and entered into the data processor. Finally, the data processor determines whether the current turning action is completed.
[0010] A further improvement of the present invention is that the middle section of the foot positioning module includes a knee turning and lifting driving component and a below-knee fitting support component, the knee turning and lifting driving component is arranged between the turning path limiting module and the tail end vertical limiting module, and the knee turning and lifting driving component is fixedly connected to the below-knee fitting support component.
[0011] A further improvement of the present invention is a method for using a critical care patient turning device that can be operated by a single person, comprising:
[0012] Step S1, the patient's foot is placed at the position of the tail end vertical limiting module, and the connection between the calf and the knee joint is fixed by the foot middle section positioning module, and the knee buckle module is rotated and adjusted by the rotation locking module, so that the rotation angle of the tail end vertical limiting module is stable, so that the patient's legs will not be hindered laterally when turning over;
[0013] Step S2, after the patient wears the tail end vertical limiting module and maintains a fixed posture, the inclination of the knee joint after turning over is adjusted through the turning over and knee lifting adjustment module. After the turning over inclination is completed, the knee turning over and lifting driving component drives the knee fitting support component to rise, so that the patient's knee is lifted. Then the mechanical arm driving unit drives the tail end vertical limiting module along the top of the turning bed frame to complete the one-way turning process.
[0014] Compared with the prior art, the present invention fixes the connection between the calf and the knee joint through the middle section positioning module of the foot, and rotates and adjusts the knee buckle module through the rotating locking module, so that the rotation inclination angle of the tail end vertical limiting module is stable, so that the patient's legs will not be hindered laterally when turning over. After the patient wears the tail end vertical limiting module and maintains a fixed posture, the turning over and knee lifting adjustment module is used to adjust the inclination of the knee joint after turning over. After the turning over inclination is completed, the knee turning over and lifting driving member drives the knee-under-fitting support member to rise, so that the patient's knee is lifted. Then the mechanical arm driving unit drives the tail end vertical limiting module to complete the one-way turning process along the top of the turning bed frame. Compared with the traditional method, the present invention simulates the lateral turning of the patient's knee joint by promoting the patient's knee joint, so that the patient's knee joint is more easily placed laterally after turning over, which is beneficial to provide support for the patient's turning over action. There is no need for multiple operators to provide knee joint support when turning over, which makes the turning over action more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

In order to better illustrate the specific embodiments of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] Example 1
[0022] See also Figure 1-Figure 4 , including a turning bed frame 1, a turning mechanical drive execution module 2 and a foot middle section positioning module 6 are installed on the upper end of the turning bed frame 1, one side of the turning mechanical drive execution module 2 is fixedly connected with a tail end vertical limiting module 5 through a mechanical arm driving unit 21, one side of the tail end vertical limiting module 5 is hingedly installed with a front foot end fixed support through a turning path limiting module 3, a turning knee raising adjustment module 4 for adjusting the turning inclination is installed between the turning path limiting module 3 and the front foot end fixed support, and the tail end vertical limiting module 5 is also installed with a turning completion detection module 7 for detecting the turning completion of the foot middle section positioning module 6.
[0023] In this embodiment, in order to solve the problem mentioned in the background technology that the patient's body pressure is concentrated on the thigh position, the nursing staff needs to apply a large thrust. Therefore, when a single nursing staff handles the patient, it is impossible to fix the patient's head, and the head is not easy to turn synchronously with the waist and legs when turning over, and the flexibility when turning over is poor. The present invention is a critical care patient turning device that can be operated by one person. By setting a turning path limitation module 3, a turning knee lifting adjustment module 4, a tail end vertical limitation module 5, a foot middle section positioning module 6 and a turning completion detection module 7, the technical problem is solved.
[0024] The turning path limiting module 3 includes a rotation locking module and a contact point adjustment module. The contact point adjustment module is used to adjust the support contact surface according to the flexion and extension state of the patient's legs. The rotation locking module is used for the contact point adjustment module to adjust the limit position after the support contact surface is adjusted.
[0025] The turning over and knee lifting adjustment module 4 comprises a knee buckle module and a restraint module. The restraint module is fixed to the outside of the tail end vertical limiting module 5. One end of the restraint module is snap-fitted and connected to the knee buckle module through a snap-fit shell.
[0026] The tail end vertical limiting module 5 is composed of an external fixing ring, a knee support buffer layer and an air cushion buffer module. The knee support buffer layer and the air cushion buffer module are fixedly connected to the inner side of the external fixing ring to support the patient's knees after they are raised when turning over.
[0027] In this embodiment, the connection between the calf and the knee joint is fixed by the middle section positioning module 6 of the foot, and the knee buckle module is rotated and adjusted by the rotating locking module, so that the rotation inclination angle of the tail end vertical limiting module 5 is stable, so that the patient's legs will not be hindered laterally when turning over. After the patient wears the tail end vertical limiting module 5 and maintains a fixed posture, the turning over and knee lifting adjustment module 4 is used to adjust the inclination of the knee joint after turning over. After the turning over inclination is completed, the knee turning over and lifting driving member drives the knee-under-fitting support member to rise, so that the patient's knee is lifted. Then, the mechanical arm driving unit 21 drives the tail end vertical limiting module 5 along the top of the turning bed frame 1 to complete the unidirectional turning process. Compared with the traditional method, the present invention simulates the lateral turning of the patient's knee joint by promoting the patient's knee joint, so that the patient's knee joint is more easily placed laterally after turning over, which is beneficial to provide support for the patient's turning over action. There is no need for multiple operators to provide knee joint support when turning over, making the turning over action more labor-saving.
[0028] The turning-over completion detection module 7 includes a post-turning contact sensing unit, a turning-over time recording unit, a data processor and a wireless signal uploading unit. After the foot middle section positioning module 6 drives the patient's legs to contact the turning-over completion detection module 7 during the auxiliary turning action, the contact signal is sensed by the post-turning contact sensing unit, and the turning-over time recording unit calculates the time required to complete the turning action and enters it into the data processor. Finally, the data processor determines whether the current turning action is completed.
[0029] The turning-over completion detection module 7 includes a post-turning contact sensing unit, a turning-over time recording unit, a data processor and a wireless signal uploading unit. After the foot middle section positioning module 6 drives the patient's legs to contact the turning-over completion detection module 7 during the auxiliary turning action, the contact signal is sensed by the post-turning contact sensing unit, and the turning-over time recording unit counts the time required to complete the turning action and enters it into the data processor. Finally, the data processor determines whether the current turning action is completed.
[0030] The working principle of the present invention is: the patient's feet are placed at the position of the tail end vertical limiting module 5, and the connection between the calf and the knee joint is fixed by the middle section positioning module 6 of the foot, and the knee buckle module is rotated and adjusted by the rotating locking module, so that the rotation angle of the tail end vertical limiting module 5 is stable, so that the patient's legs will not be laterally hindered when turning over. After the patient wears the tail end vertical limiting module 5 and maintains a fixed posture, the inclination of the knee joint after turning over is adjusted by the turning over and knee lifting adjustment module 4. After the turning over inclination is completed, the knee turning over and lifting driving member drives the knee-under-knee fitting support member to rise, so that the patient's knee is lifted, and then the mechanical arm driving unit 21 drives the tail end vertical limiting module 5 along the top of the turning bed frame 1 to complete the one-way turning process.
[0031] Example 2
[0032] See also Figure 1-Figure 4 In this embodiment, a turning-over bed frame 1 is provided with a turning-over mechanical driving execution module 2 and a foot middle section positioning module 6 at the upper end, and a tail end vertical limiting module 5 is fixedly connected to the turning-over mechanical driving execution module 2 on one side thereof, and a front foot end fixed support is hingedly installed on one side of the tail end vertical limiting module 5 through a turning-over path limiting module 3, and a turning-over knee raising adjustment module 4 for adjusting the turning inclination is installed between the turning-over path limiting module 3 and the front foot end fixed support, and a turning-over completion detection module 7 for detecting the turning completion of the foot middle section positioning module 6 is also installed on the tail end vertical limiting module 5.
[0033] The turning-over completion detection module 7 includes a post-turning contact sensing unit, a turning-over time recording unit, a data processor and a wireless signal uploading unit. After the foot middle section positioning module 6 drives the patient's legs to contact the turning-over completion detection module 7 during the auxiliary turning action, the contact signal is sensed by the post-turning contact sensing unit, and the turning-over time recording unit counts the time required to complete the turning action and enters it into the data processor. Finally, the data processor determines whether the current turning action is completed.
[0034] In this embodiment, the same points as those in Embodiment 1 are not repeated here, but the difference from Embodiment 1 is that the connection between the calf and the knee joint is fixed by the foot middle section positioning module 6, and the knee buckle module is rotationally adjusted by the rotation locking module, so that the rotation angle of the tail end vertical limiting module 5 is stable, so that the patient's legs will not be hindered laterally when turning over. After the patient wears the tail end vertical limiting module 5 and maintains a fixed posture, the inclination of the knee joint after turning over is adjusted by the turning over and knee lifting adjustment module 4. After the turning over inclination is completed, the knee turning over and lifting driving member drives the knee fitting support member to rise, so that the patient's knee is lifted, and then the robot arm drives the patient to turn over and lift the knee. The driving unit 21 drives the tail end vertical limiting module 5 to complete the one-way turning process along the top of the turning bed frame 1. After completing the above operations, the contact signal of the patient's knee joint after turning over is sensed by the setting of the contact sensing unit after turning over, and it is determined whether the current knee completeness meets the placement requirements after turning over. After the contact signal of the contact sensing unit is triggered, the turning time recording unit is used to calculate the time required to complete the turning action and enter it into the data processor. Finally, the data processor determines whether the current turning action is completed. If not, a signal requiring manual intervention is sent to the medical terminal, so that the nursing staff can quickly reach the nursing area where the turning bed frame 1 is located for manual assistance.
