Description

Technical Field

[0001] The present invention relates to the technical field of medical care, and specifically, to a body position auxiliary holding device for stroke patients. Background Art

[0002] A stroke is a disease caused by the sudden rupture of blood vessels in the brain or the blockage of blood vessels leading to brain tissue damage. During the rehabilitation process of stroke patients, the correct body position placement is crucial. The healthy side lying position means that the patient lies with the healthy side down and the affected side up. This body position can avoid the direct bearing of large pressure on the affected side, is beneficial to the blood circulation of the affected limb, reduces the occurrence of swelling and pain, and creates good conditions for subsequent rehabilitation training.

[0003] Nowadays, when adjusting a patient to the healthy side lying position, medical staff first need to turn the patient to the side and then find a pillow to support the upper and lower limbs of the hemiplegic side of the patient. The lower limb is in a stepping state. Due to the presence of consciousness disorders in stroke patients, it is difficult for one person to complete this work, and the workload is high, bringing great inconvenience to the nursing work. Due to the limitations of the physical functions of stroke patients, the affected side often cannot move independently, which brings many challenges to the nursing work. During the traditional nursing process, medical staff may need to make multiple adjustments when turning over the patient. This not only consumes time and energy, but may also cause the patient's resistance and discomfort, and even affect the patient's rehabilitation process and psychological state to a certain extent.

[0004] In response to this, for stroke patients, some hospital beds are equipped with electric control auxiliary mechanisms to provide convenience and nursing support for patients. However, these devices usually require medical staff to operate in strict accordance with a specific order. If the operation order is incorrect, not only may the expected nursing effect not be achieved, but it may also cause damage to the patient. For example, when using the electric control auxiliary mechanism for body position transformation, an incorrect operation order may cause uneven force on the patient's body, resulting in discomfort or aggravating the condition. Therefore, for these electric control auxiliary mechanisms, medical staff need to receive strict training, be familiar with and master the correct operation process to ensure the safety of the patient and the effective use of the equipment.

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0040] Please refer to Figures 1-9 , in an embodiment of the present invention, a body position assisting and maintaining device for stroke patients includes a bed body 1 and a bottom cushion 2 disposed on the bed body 1, and further includes:

[0041] Lifting mechanisms, symmetrically provided in two groups on the bed body 1 and respectively connected to both sides of the bottom cushion 2. The lifting mechanisms can perform a traction action on the bottom cushion 2 to make the patient turn sideways. Each of the two groups of lifting mechanisms is also connected to a group of filling mechanisms, and the filling mechanisms are used to fill the gap between the bottom cushion 2 and the patient's back after the patient turns sideways;

[0042] Auxiliary supporting mechanisms, each provided in a group on both sides of the bed body 1;

[0043] Slider 22, two are provided at the bottom of the bed body 1. The two sliders 22 can move along the length direction of the bed body 1 and respectively trigger the auxiliary support mechanism, the lifting mechanism and the filling mechanism.

[0044] Furthermore, there are many choices for the body position of stroke patients. During the rehabilitation process of stroke patients, the correct body position placement is crucial. It can effectively prevent or reduce the occurrence of spasm and deformity, prevent the occurrence of complications and secondary damage, and has a positive promoting effect on the rehabilitation of patients. The body position realized by this application is the healthy side lying position. Specifically, the healthy side of the patient is below and the affected side is above. A pillow is placed under the head and a pillow is placed in front of the chest. The affected upper limb extends forward, the shoulder joint is flexed about 90°, and a pillow is placed under the shoulder. The healthy upper limb can be placed freely; the affected lower limb hip and knee joints are flexed and placed on the pillow, and the healthy lower limb hip joint is extended and the knee joint is slightly flexed. This body position can prevent and treat the spasm of the flexor muscles of the affected upper limb and the extensor muscles of the lower limb, and help improve the patient's self-care ability and promote the rehabilitation process;

[0045] Combined with the above structural description of this application, during use, the two sliders 22 are respectively located on the affected side and the healthy side of the patient. The slider 22 located on the affected side of the patient moves along the length direction of the bed body 1 at the bottom of the bed body 1. First, the slider 22 will trigger the auxiliary support mechanism located on the healthy side of the patient. The auxiliary support mechanism on this side performs a flipping action to provide a placement platform for the affected limb after the patient turns over. Specifically, the affected upper limb extends forward, and the hip and knee joints of the affected lower limb are flexed and placed on this platform;

[0046] Immediately afterwards, the lifting mechanism is triggered. The lifting mechanism located on the affected side of the patient is triggered. This lifting mechanism pulls the bottom pad 2. Then, the bottom pad 2 can play a role in lifting the affected side of the patient upward to assist the patient in turning over. Finally, the filling mechanism is triggered. The filling mechanism can inflate the side of the bottom pad 2 close to the affected side of the patient to fill the gap between the bottom pad 2 and the patient's back at this time, acting as an automatic replenishment pillow;

[0047] In the context of the continuous progress of today's medical technology, the innovative design involved in this application cleverly combines the side-turning assistance, support assistance and inflation functions into one, opening up a new way for the field of patient care. In the actual application process, through a carefully designed mechanism, selecting to drive the slider 22 located on the affected side of the patient to move along the length direction of the bed can sequentially trigger the auxiliary support mechanism, the lifting mechanism and the filling mechanism in an orderly manner. This process is not only clear and orderly, but more importantly, when performing healthy side lying position care for stroke patients, it does not completely rely on the manual operation of medical staff, thus greatly reducing the work intensity of medical staff and significantly improving the convenience and efficiency of medical care work.

[0048] This innovative nursing device not only integrates multiple auxiliary functions, but also reflects the dual care for patients and medical staff in actual operation. For patients, the automated operation process of the device can reduce the discomfort and resistance caused by frequent manual adjustments, making the body position conversion process smoother and more comfortable, helping patients maintain a positive rehabilitation mentality, and thus promoting the improvement of overall rehabilitation effects. For medical staff, the application of the device can save more time and energy, allowing them to focus more on the patient's rehabilitation training and psychological support, thereby improving the work efficiency and service quality of the entire nursing team.

[0049] In addition, this innovative design is forward-looking and market-competitive. As people's requirements for medical equipment become higher and higher, product design must not only meet the functional requirements, but also focus on user experience and ease of operation. The innovative care solution advocated by this application is a positive response to this market demand, and is expected to occupy a place in the future medical equipment market, bringing new breakthroughs and hope to the care of stroke patients.

[0050] In today's medical practice, stroke patients often lose the ability to move their affected limbs independently due to the serious damage to their body functions caused by the disease. This situation undoubtedly brings many difficulties and challenges to nursing work. In the past, under the traditional nursing model, when medical staff assist patients in turning over, they often need to repeatedly adjust the patient's body posture to ensure that the patient changes position comfortably and safely. However, this process not only consumes a lot of time and energy of medical staff, but also during the adjustment process, patients may resist due to discomfort or pain, and even feel irritable due to frequent interference, which reduces their cooperation with rehabilitation training and affects their overall rehabilitation process and mental health.

[0051] The innovative nursing program advocated by this application is carefully designed to address this series of problems. It cleverly introduces automated and orderly operating procedures. Through precise program control and the assistance of intelligent devices, the patient's position change can be completed quickly and smoothly at one time without multiple adjustments. This one-stop position switching method not only greatly saves the working time of medical staff, allowing them to devote more energy to other key nursing tasks, but also significantly improves the comfort and satisfaction of patients. The discomfort and interference felt by patients during the position change process are greatly reduced, so that they can face rehabilitation training with a more positive and relaxed attitude, enhance their confidence and participation in the rehabilitation process, and ultimately effectively promote the significant improvement of the overall rehabilitation effect of patients, promote their recovery of physical functions as soon as possible, and return to normal life.

[0052] Please refer again Figure 6 andFigure 7 The lifting mechanism includes a lifting plate 4 slidably disposed on the side of the bed body 1. Connecting straps 26 are provided on both sides of the bottom pad 2. One end of each connecting strap 26 away from the bottom pad 2 is connected to the top end of the lifting plate 4 by a buckle. It further includes:

[0053] An assembly plate 5, fixed to the bottom of the bed body 1 and having a hollow interior, in which an elastic sliding assembly that cooperates with the slider 22 and is connected to the lifting plate 4 is provided.

[0054] The elastic sliding assembly includes a guide shaft 6 fixed inside the assembly plate 5 and a sleeve 8 slidably sleeved on the guide shaft 6. A first spring 7 is further sleeved on the outer periphery of the guide shaft 6. Two ends of the first spring 7 are respectively connected to the inner wall of the assembly plate 5 and the sleeve 8. A first lug 801 extending outside the assembly plate 5 is fixed to the outer wall of the sleeve 8. A second lug 2201 is fixed to the side of the slider 22. A connecting rod 9 is provided between the sleeve 8 and the lifting plate 4. Two ends of the connecting rod 9 are respectively hinged to the sleeve 8 and the lifting plate 4.

[0055] When adjusting the patient's body position, the slider 22 moves along the length direction of the bed body 1 at the bottom of the bed body 1. Before the second lug 2201 contacts the first lug 801, the auxiliary supporting mechanism on the healthy side of the patient is triggered to perform a flipping action. After the patient turns sideways, a placement platform is provided for the affected limb of the patient, eliminating the step of medical staff placing a pillow to support the affected limb of the patient;

[0056] After the second lug 2201 contacts the first lug 801, the slider 22 can push the sleeve 8 to slide away from the lifting plate 4 on the guide shaft 6 through the second lug 2201 and the first lug 801 (a strip-shaped through groove for the first lug 801 to extend and move is provided on the side of the assembly plate 5). The first spring 7 is compressed. Correspondingly, the sleeve 8 pulls the lifting plate 4 to rise through the connecting rod 9, and the lifting plate 4 generates an upward pulling force on the bottom pad 2 through the connecting strap 26, thereby effectively assisting the patient to turn sideways.

[0057] Please refer to again Figure 6 , two compartments are provided in the bottom pad 2. Elastic mesh openings 201 are provided on the compartments. Air bags are provided inside the compartments. The air bags can be connected to the filling mechanism through conduits.

[0058] Furthermore, during specific implementation, before the patient is transferred to the bed body 1, the medical staff needs to lay the bottom pad 2 on the bed body 1 in advance. The bottom pad 2 is laid between the two lifting plates 4. After the laying is completed, the connecting straps 26 on both sides of the bottom pad 2 are respectively connected to the two lifting plates 4 through buckles. The connection method of the buckles is convenient for the staff to replace;

[0059] Secondly, the airbag is provided with an inflation port. Before adjusting the patient's body position, the medical staff needs to connect the inflation port on the affected side of the patient to a catheter, and the other end of the catheter is connected to the filling mechanism on the same side. After the patient lies on the side, the filling mechanism can inflate the airbag on the affected side of the patient through the catheter. Thus, the inflation of the airbag can effectively fill the gap between the patient's affected side back and the bottom pad 2, making the maintenance of the patient's current body position more stable.

[0060] Please refer to again Figure 8 and Figure 9 , the filling mechanism includes a cylinder 13 fixed to the bottom of the bed body 1 and a piston disk 14 slidably sealed in the cylinder 13. The end of the cylinder 13 is provided with a connection port for connecting the catheter; wherein, the piston disk 14 is connected to two sets of ejection structures arranged in the cylinder 13. The piston disk 14 is fixedly connected with a cylindrical protrusion 19 through a connecting column 17 and an extension arm 18. The cylindrical protrusion 19 cooperates with a follower plate 11 fixedly connected to the sleeve 8 through a connecting arm 10.

[0061] The follower plate 11 is provided with a groove body adapted to the cylindrical protrusion 19. The cylindrical protrusion 19 extends into the groove body and is slidably connected to the follower plate 11. The groove body includes a first guide groove 1101, a second guide groove 1102, a third guide groove 1103, and a fourth guide groove 1104 connected in sequence;

[0062] Among them, the first guide groove 1101 and the second guide groove 1102 are collinear. The third guide groove 1103 is perpendicular to the second guide groove 1102 and the fourth guide groove 1104. The length of the fourth guide groove 1104 is less than the length of the second guide groove 1102, and a fifth guide groove 1105 is connected between the fourth guide groove 1104 and the first guide groove 1101 and the second guide groove 1102; A flap 12 is also hinged on the follower plate 11. The flap 12 is located at one end of the fifth guide groove 1105 away from the fourth guide groove 1104, and the rotating shaft of the flap 12 is connected with a torsion spring.

[0063] Specifically, during the process of compression of the first spring 7, the follower plate 11 moves together with the sleeve 8 through the connecting arm 10. Thus, the first guide groove 1101 and the second guide groove 1102 sequentially pass by the cylindrical protrusion 19 (the paddle 12 cannot deflect into the fifth guide groove 1105). After the connection between the second guide groove 1102 and the third guide groove 1103 corresponds to the cylindrical protrusion 19, the limiting state of the follower plate 11 on the cylindrical protrusion 19 is released. Immediately afterwards, the ejection mechanism is triggered to release the elastic potential energy, driving the piston disc 14 to slide within the cylinder 13, pumping the air within the cylinder 13 to the airbag through the conduit, promoting the inflation of the airbag, filling the gap between the affected side of the patient's back and the bottom pad 2, and making the maintenance of the patient's current body position more stable;

[0064] Generally, the healthy side lying position of a stroke patient needs to be changed back after 1 - 2 hours. Regularly changing the body position can prevent the occurrence of complications such as pressure sores, and is also beneficial to the patient's blood circulation and rehabilitation;

[0065] Specifically, the slider 22 gradually moves in the reverse direction to reset. Correspondingly, the first spring 7 will gradually extend to its original length. During this process, the fourth guide groove 1104, the fifth guide groove 1105, and the first guide groove 1101 sequentially pass by the cylindrical protrusion 19 (the paddle 12 flips towards the second guide groove 1102). Since the length of the fourth guide groove 1104 is less than that of the second guide groove 1102, the fifth guide groove 1105 is inclined. When passing by the cylindrical protrusion 19, it will cause the cylindrical protrusion 19 to perform a sliding fit with the follower plate 11. The cylindrical protrusion 19 drives the piston disc 14 to slide towards the outside of the cylinder 13 through the extension arm 18 and the connecting column 17. The airbag is deflated, and the cylindrical protrusion 19 corresponds to the end of the first guide groove 1101 away from the second guide groove 1102 again.

[0066] The ejection structure includes a fixed shaft 15 fixed within the cylinder 13 through a protrusion block 1301 and passing through the piston disc 14. The piston disc 14 is in sealed sliding connection with the fixed shaft 15. A second spring 16 with both ends respectively connected to the piston disc 14 and the protrusion block 1301 is also sleeved on the outer periphery of the fixed shaft 15.

[0067] Initially, the cylindrical protrusion 19 is located at one end of the first guide groove 1101 away from the second guide groove 1102, and the second spring 16 is in a compressed state. When the connection between the second guide groove 1102 and the third guide groove 1103 corresponds to the cylindrical protrusion 19, the second spring 16 can rebound, enabling the piston disc 14 to move towards the inside of the cylinder 13, and pumping the air in the cylinder 13 into the airbag through the conduit, providing guarantee for the stable maintenance of the patient's body position.

[0068] Please refer to again Figure 5 , the auxiliary supporting mechanism includes a receiving platform 3 rotatably installed at the bottom of the bed body 1. The receiving platform 3 is connected by a belt 24 to a transmission shaft 23 rotatably installed at the bottom of the bed body 1. A follower tube 25 fixedly connecting the slider 22 is slidably sleeved on the transmission shaft 23;

[0069] Wherein, a convex column is fixed on the follower tube 25, and a groove adapted to the convex column is provided on the transmission shaft 23. The convex column extends into the groove and is slidably connected to the transmission shaft 23. The groove includes a first chute 2301 and a second chute 2302 connected to each other. The first chute 2301 is spirally arranged, and the second chute 2302 is arranged along the axial direction of the transmission shaft 23.

[0070] A guide rail 20 is fixedly provided at the bottom of the bed body 1. The slider 22 is slidably fitted into the guide rail 20. A lead screw 21 is also rotatably installed at the bottom of the bed body 1. The lead screw 21 passes through the slider 22 and is threadedly connected to the slider 22.

[0071] It should be added that the lead screw 21 is also connected to a servo motor. During operation, the servo motor can drive the lead screw 21 to rotate forward or backward. Specifically, when the lead screw 21 rotates forward, under the guiding action of the guide rail 20, the slider 22 will slide along the guide rail 20 in sliding cooperation with the lead screw 21 (i.e., slide along the length direction of the bed body 1). Correspondingly, the follower tube 25 moves together with the slider 22. Before the second lug 2201 contacts the first lug 801, the convex column on the follower tube 25 is in sliding cooperation with the transmission shaft 23 through the first chute 2301, so that the transmission shaft 23 rotates. The transmission shaft 23 drives the receiving platform 3 on the healthy side of the patient to turn over through the belt 24, providing a placement platform for the affected limb after the patient turns over later;

[0072] Therefore, the servo motor and the lead screw 21, as the driving sources, can accurately and orderly trigger the auxiliary supporting mechanism, the lifting mechanism, and the filling mechanism in sequence. At the same time, the threaded fit between the slider 22 and the lead screw 21 has the characteristics of high-precision driving, good stability, and self-locking. The so-called high-precision driving means that this fit can ensure the precise execution of each action, enabling precise control of every subtle movement during the adjustment of the patient's body position; good stability ensures that during the body position adjustment, the patient's body will not feel discomfort or pose a safety hazard due to the shaking or instability of the device; self-locking provides an additional guarantee for the patient's safety. Even in the event of a sudden power outage or an accident, the patient's position can remain stable and will not slide or fall. The combined effect of these characteristics can effectively improve the comfort and sense of security of the patient during the body position adjustment process, thus greatly optimizing the patient's usage experience.

[0073] During the rehabilitation process of stroke patients, it is necessary to regularly maintain the healthy-side lying position, that is, the patient lies on the healthy side with the affected side on top. This body position can avoid the direct bearing of large pressure on the affected side and is beneficial to the blood circulation of the affected limb. The patient can control the action of the servo motor by pressing the button at the head of the bed body 1 to achieve automatic control. The servo motor establishes communication with a remote control unit (such as the operation terminal of medical staff). Medical staff can monitor and operate the action of the bed body 1 in real time through the remote control unit. The remote control unit has a graphical user interface (GUI) that displays the real-time status of the bed body 1 and the vital sign data of the patient. When the patient is inconvenient to operate or medical staff need to conduct an examination, medical staff can take over the control right through the remote control unit to achieve the combined online and offline diagnosis and treatment operations.

[0074] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
