Description

Technical Field

[0001] This invention relates to the field of rehabilitation therapy technology, and in particular to a traction device for lumbar spine rehabilitation treatment. Background Technology

[0002] Lumbar spine diseases are diverse and often cause symptoms such as lower back pain and numbness in the lower limbs. Traction therapy is a method that uses external force to apply traction to a part of the body or joint, causing a certain degree of separation and appropriate stretching of the surrounding soft tissues, thereby achieving the therapeutic goal. It is widely used in lumbar spine rehabilitation treatment, and the supine lumbar spine rehabilitation traction device is the key equipment to achieve this treatment.

[0003] Existing lumbar traction devices for supine lumbar rehabilitation treatment often have straps at both ends of the traction bed to fix the lower edge of the costal arch in the upper body and the upper edge of the iliacus muscle in the lower body, respectively. To enhance the fixation effect, the straps are further tightened by referencing the design of vehicle seat strap buckles, and then lumbar traction rehabilitation treatment is achieved through mechanical traction.

[0004] However, elderly patients often suffer from osteoporosis due to aging, resulting in decreased bone density, strength, and toughness, and a significant reduction in their ability to withstand pressure. When the existing device's strap buckle is tightened, it causes concentrated pressure on the patient's body. Combined with mechanical traction, the pressure further increases, which can easily cause compression damage to the bones and soft tissues of elderly patients at the points of contact with the strap, thereby affecting the effectiveness of rehabilitation treatment. Summary of the Invention

[0005] This invention provides a supine lumbar spine rehabilitation traction device to solve the technical problem in the prior art where the strap buckle causes concentrated pressure on the patient's body when locked, and the pressure is further increased by mechanical traction, which can easily cause compression damage to the bones and soft tissues of elderly patients at the contact points with the strap, thereby affecting the rehabilitation effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A horizontal lumbar spine rehabilitation traction device includes a traction bed, a connecting frame at the top of the traction bed, a bed board of the traction bed sliding with the connecting frame, an airbag inside the connecting frame, a support frame at the top of the airbag, the airbag inflating to support the support frame bending along the axis, the support frame being movably engaged with the connecting frame, and straps on both sides of the connecting frame.

[0008] The connecting frame is equipped with a limiting component, which limits the lower body of the patient.

[0009] Optionally, the limiting component includes two limiting frames. The inner walls on both sides of the connecting frame are provided with a first guide block and a second guide block. The limiting frame slides within the first guide block and the second guide block. The first guide block is provided with a toggle frame on the side near the second guide block. The toggle frame abuts against the limiting frame.

[0010] Optionally, the limiting frame includes a first limiting part and a second limiting part, with a fitting part between the first limiting part and the second limiting part. The end of the first limiting part away from the fitting part is provided with a first sliding part, a connecting part and a second sliding part in sequence. The end of the second sliding part away from the connecting part is connected to the end of the second limiting part away from the fitting part. The connection between the connecting part and the second sliding part abuts against the actuating frame.

[0011] Optionally, the actuating frame includes a connecting part, one end of which is connected to one side of the first guide block, and the other end of which is provided with a bending part and a actuating part in sequence, the actuating part abutting against the connection between the connecting part and the second sliding part.

[0012] Optionally, both sides of the traction bed are provided with abutment frames, and one side of the abutment frame is provided with a limiting pin. The two limiting pins pass through the corresponding abutment frames and are threaded to the two sides of the traction bed respectively. The two abutment frames are respectively attached to the outer walls of the two sides of the connecting frame.

[0013] Optionally, the abutment frame includes a handheld part that abuts against one side of the traction bed. One side of the handheld part has an arc-shaped part with a gap between the bottom of the arc-shaped part and the top of the traction bed. The side of the arc-shaped part away from the handheld part is in contact with the outer wall of the connecting frame. One end of the handheld part away from the arc-shaped part has an abutment part. The connecting frame has openings on both sides, and the abutment part passes through the openings and abuts against the connection between the first sliding part and the connecting part.

[0014] Optionally, the support frame includes a support portion, with receiving portions on both sides of the support portion, and a guide portion on the outer wall of the receiving portion, the guide portion being slidably connected to the inner wall of the connecting frame.

[0015] Optionally, guide grooves are provided on both sides of the connecting frame, the number of guide grooves is equal to the number of guide parts, and the position of each guide groove corresponds to the position of the guide part, and the guide part slides in the guide groove.

[0016] Optionally, there is a gap between the guide portion and the first limiting portion and the second limiting portion, and clearance notches are provided on both sides of the support portion.

[0017] Optionally, the bottom of the connecting frame is provided with a positioning seat, which engages with the bed board of the traction bed.

[0018] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0019] In the above-mentioned scheme, by setting up a limiting component, it can not only simultaneously conform to the patient's external oblique muscle, tensor fasciae latae muscle, and vastus lateralis muscle, effectively limiting the patient's lower body, but also effectively disperse the pressure concentrated on the band, avoiding the concentrated pressure caused by the band tightening that could harm the patient's body. Furthermore, it can adaptively increase the tightening force as the traction force increases, avoiding damage caused by excessive tightening. It fully considers the characteristics of elderly patients with weaker physical endurance, effectively protecting the patient's physical safety while ensuring the treatment effect, and is conducive to improving the effect of lumbar traction therapy.

[0020] By setting up a limiting frame, a shifting frame, and an abutment frame, the limiting frame can simultaneously conform to the patient's external oblique muscle, tensor fasciae latae muscle, and vastus lateralis muscle, effectively limiting the patient's lower body and effectively dispersing the pressure concentrated on the strap. The coordination of the shifting frame and the abutment frame allows the limiting frame to adaptively increase the tightening force on the patient's body as the traction force increases, avoiding damage caused by excessive tightening and thus improving the effect of lumbar traction therapy.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0033] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0034] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0035] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0036] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0037] like Figures 1 to 9 As shown, an embodiment of the present invention provides a supine lumbar spine rehabilitation traction device, including a traction bed 1. The structure and operating principle of the traction bed 1 are disclosed in the prior art and will not be described in detail here. The top of the traction bed 1 is provided with a connecting frame 2, and an airbag 3 is provided inside the connecting frame 2. The airbag 3 consists of two independently controlled small airbags. When the airbag 3 is inflated, it expands from the center to both sides, making the small airbags on both sides fan-shaped, which is used to assist the patient in getting up. The inflation and deflation of the airbag 3 and the control principle are also disclosed in the prior art and will not be described in detail here. The airbag 3 has a support frame 4 at its top, which is slidably connected to the connecting frame 2. The connecting frame 2 has straps 30 on both sides, preferably Velcro, which facilitates patient wearing and provides basic positioning. During use, the patient lies supine or prone as needed. Medical staff attach the straps 30 to the patient's body and, according to the doctor's orders, activate the traction bed 1 to perform traction treatment on the patient's lumbar spine. After treatment, a small airbag in the airbag 3 is activated according to the patient's lying position. The small airbag inflates into a fan shape, and the support frame 4, propelled by the small airbag, assists the patient in getting up from their side after treatment, effectively reducing the strain on the lower back and ensuring the traction effect. The airbag 3 gradually changes the patient's position by pushing the support frame 4, allowing for a more stable adjustment of blood circulation in different parts of the body. This effectively avoids uneven redistribution of blood due to rapid changes in position, reducing the likelihood of dizziness caused by the patient getting up after traction treatment and ensuring patient safety.

[0038] The limiting component is connected to the connecting frame 2. The limiting component is used to assist in limiting the lower body of the patient. When in use, the limiting component can simultaneously conform to the patient's external oblique muscle, tensor fasciae latae muscle, and vastus lateralis muscle, effectively limiting the lower body of the patient. It effectively disperses the pressure concentrated on the strap 30, avoiding the concentrated pressure caused by the strap 30 locking and causing injury to the patient's body. It can also adaptively increase the tightening force as the traction force increases, avoiding damage to the patient caused by excessive tightening. It fully considers the characteristics of elderly patients with weak physical endurance, effectively protecting the patient's body safety while ensuring the treatment effect, and is conducive to improving the effect of lumbar traction therapy.

[0039] like Figure 1 , Figure 4 and Figure 7 As shown, the limiting assembly includes two limiting frames 11, which are symmetrically arranged on both sides of the connecting frame 2. The inner walls of both sides of the connecting frame 2 are provided with a first guide block 5 and a second guide block 6. The limiting frame 11 is slidably connected in the first guide block 5 and the second guide block 6. The first guide block 5 is provided with a toggle frame 7 on the side near the second guide block 6. The protruding toggle frame 7 abuts against the limiting frame 11. The limiting frame 11 is shaped with protrusions at both ends and a concave middle. The two ends of the limiting frame 11 are slidably inserted into the first guide block 5 and the second guide block 6, respectively. The toggle frame 7 abuts against the middle position of the limiting frame 11. The middle part of the limiting frame 11 protrudes towards the toggle frame 7, that is, the side of the limiting frame 11 facing the axis of the connecting frame 2 is concave.

[0040] In use, the two limiting frames 11 correspond to and fit the external oblique muscles, tensor fasciae latae, and vastus lateralis muscles on both sides of the patient's body, respectively. Together with the wearing of the strap 30, they effectively limit the lower body of the patient and effectively disperse the pressure concentrated on the strap 30. When the traction force is increased according to the doctor's orders, the force applied by the patient's body during traction drives the actuating frame 7. Under the actuating action of the actuating frame 7, the limiting frame 11 slides within the first guide block 5 and the second guide block 6, thereby realizing that the limiting frame 11 adaptively increases the tightening force on the patient's body as the traction force increases. This avoids damage to the patient caused by excessive tightening, fully considers the characteristics of elderly patients with weaker physical endurance, and effectively protects the patient's body safety while ensuring the treatment effect, which is conducive to improving the effect of lumbar traction treatment.

[0041] like Figure 5 and Figure 6As shown, the limiting frame 11 includes a first limiting part 18 and a second limiting part 20. A fitting part 19 is provided between the first limiting part 18 and the second limiting part 20. The end of the first limiting part 18 away from the fitting part 19 is provided with a first sliding part 21, a connecting part 22 and a second sliding part 23 in sequence. The end of the second sliding part 23 away from the connecting part 22 is connected to the end of the second limiting part 20 away from the fitting part 19. The first limiting part 18 and the second limiting part 20 protrude towards the axis of the connecting frame 2, and the fitting part 19 is recessed towards the axis of the connecting frame 2.

[0042] The connection between the connecting part 22 and the second sliding part 23 abuts against the actuating frame 7. In use, the first limiting part 18, the fitting part 19, and the second limiting part 20 fit against the external oblique muscle, tensor fasciae latae muscle, and vastus lateralis muscle on both sides of the patient, respectively. Combined with the wearing of the strap 30, this effectively limits the lower body of the patient. When the traction force is increased according to the doctor's orders, the first sliding part 21 and the second sliding part 23 slide within the first guide block 5 and the second guide block 6, respectively, under the actuating action of the actuating frame 7. This allows the limiting frame 11 to adaptively increase the tightening force on the patient's body as the traction force increases, avoiding damage caused by excessive tightening. The degree of protrusion of the first sliding part 21 and the second sliding part 23 within the first guide block 5 and the second guide block 6 can be controlled as the first sliding part 21 and the second sliding part 23 slide, thereby controlling the tightening force.

[0043] like Figures 2 to 6 As shown, the actuating frame 7 includes a connecting part 8. One end of the connecting part 8 is connected to one side of the first guide block 5. The other end of the connecting part 8 is provided with a bending part 9 and an actuating part 10 in sequence. The actuating part 10 abuts against the connection of the connecting part 22 and the second sliding part 23. When the traction force is increased according to the doctor's order, the first sliding part 21 and the second sliding part 23 slide in the first guide block 5 and the second guide block 6 respectively. When traction is applied, the first sliding part 21 slides upward under the force. The actuating part 10 applies a downward sliding force to the second sliding part 23 under the connection of the bending part 9 and the connecting part 8, so that the sliding direction of the second sliding part 23 is opposite to that of the first sliding part 21. This causes the first limiting part 18 and the second limiting part 20 to tighten in the direction of the axis of the connecting frame 2. Thus, the limiting frame 11 increases the tightening force on the patient's body as the traction force increases, avoiding damage to the patient caused by excessive tightening. Specifically, the connecting part 22 can deform, and under the action of the abutting part 16 and the actuating part 10, the connecting part 22 deforms and pushes the second sliding part 23 downward to push the second limiting part 20 to tighten the human body.

[0044] like Figures 1 to 6As shown, the traction bed 1 has abutment frames 13 on both sides, and each abutment frame 13 has a limiting pin 14 on one side. The two limiting pins 14 pass through the abutment frames 13 and are threadedly connected to both sides of the traction bed 1. The side walls of the two abutment frames 13 are respectively attached to the outer walls of both sides of the connecting frame 2. The abutment frames 13 are used to limit the position of the connecting frame 2 on the traction bed 1, thereby further ensuring the safety and stability of the patient's lumbar traction treatment. In use, the connecting frame 2 is placed on top of the traction bed 1, one side of the abutment frame 13 is attached to the side wall of the connecting frame 2, and then the limiting pins 14 are tightened.

[0045] like Figures 4 to 6 As shown, the abutment frame 13 includes a handle 15, which abuts against one side of the traction bed 1. One side of the handle 15 has an arc-shaped portion 17, with a gap between the bottom of the arc-shaped portion 17 and the top of the traction bed 1. The side of the arc-shaped portion 17 away from the handle 15 is fitted against the outer wall of the connecting frame 2. One end of the handle 15 away from the arc-shaped portion 17 has an abutment portion 16. Both sides of the connecting frame 2 have openings 12, through which the abutment portion 16 passes and abuts against the connection between the first sliding portion 21 and the connecting portion 22. When the connecting frame 2 is placed on top of the traction bed 1, medical personnel can hold the handle 15 to press the arc-shaped portion 17 of the abutment frame 13 against the side wall of the connecting frame 2 and tighten the limiting pin 14. It is understood that the limiting pin 14 is threadedly connected to the bed frame of the traction bed 1. The connecting frame 2 is placed on the bed board at the top of the traction bed 1. The bed board is driven by a linear drive mechanism and can slide on top of the bed frame to change the traction force. This is existing technology and will not be described in detail here. Simultaneously, the abutment part 16 passes through the opening 12 and abuts against the connection between the first sliding part 21 and the connecting part 22. When medical staff increase the traction force according to the doctor's orders, the position of the abutment frame 13 is relatively fixed. The connecting frame 2 and its upper support frame 4 drive the patient's lower body to move synchronously with the movement of the bed board. It can be understood that the patient's upper body is limited by the handrail and the patient's armpits in the existing technology, which will not be elaborated on here. The abutment part 16 slides in the opening 12. As the traction force increases, the abutment force of the abutment part 16 against the connection between the first sliding part 21 and the connecting part 22 becomes greater, thereby tightening the first limiting part 18 and the second limiting part 20 inward. Thus, the limiting frame 11 increases the binding force on the patient's body as the traction force increases, avoiding damage to the patient caused by excessive tightening.

[0046] like Figure 8 and Figure 9As shown, the support frame 4 includes a support portion 24, a bendable portion at the axis of the support portion 24, receiving portions 25 on both sides of the support portion 24, and a guide portion 26 on the outer wall of the receiving portion 25. The guide portion 26 is slidably connected to the connecting frame 2. The support portion 24 is used to support the patient's body, and the receiving portion 25 is used to connect the support portion 24 and the guide portion 26. After the patient's lumbar traction treatment is completed, according to the patient's lying position, the airbag 3 is activated, causing one small airbag to inflate into a fan shape, pushing the support portion 24 to bend to one side, assisting the patient to get up from the side after treatment. This can effectively reduce the force on the lower back when the patient gets up, thereby ensuring the traction effect. The airbag 3 pushes the support frame 4 to gradually change the patient's body position, allowing the blood circulation in various parts of the body to be adjusted more smoothly. This effectively avoids uneven redistribution of blood due to rapid changes in body position, reduces the probability of dizziness caused by the patient getting up on their own after traction treatment, and ensures the patient's safety.

[0047] like Figure 2 and Figure 7 As shown, guide grooves 27 are provided on both sides of the connecting frame 2. The number of guide grooves 27 is equal to the number of guide parts 26, and the positions of the guide grooves 27 and guide parts 26 correspond one-to-one. In this embodiment, there are two guide parts 26 on one side of the support part 24, for a total of four guide parts 26. The guide parts 26 are slidably inserted into the guide grooves 27, providing guidance for the movement of the support frame 4. During the process of the airbag 3 pushing the support part 24 to bend to one side from the axis to assist the patient in turning over, the guide grooves 27 can restrict the movement trajectory of the guide parts 26, ensuring that the guide parts 26 can move along the direction of the guide grooves 27 without deviation or shaking. This makes the support frame 4 move smoothly and reliably when changing the patient's position, avoiding additional injury or discomfort to the patient due to unstable movement.

[0048] like Figure 4 , Figure 5 and Figure 8 As shown, there is a gap between the guide portion 26 and the first limiting portion 18 and the second limiting portion 20. The support portion 24 has clearance notches 28 on both sides. During the process of the airbag 3 pushing the support frame 4 to assist the patient in turning over from a side-lying position, the support frame 4 needs to move relative to the connecting frame 2 to a certain extent. The gap between the guide portion 26 and the first limiting portion 18 and the second limiting portion 20 allows the guide portion 26 to slide smoothly within the guide groove 27, ensuring the flexibility and stability of the support frame 4's movement and making the patient's position adjustment process more comfortable and natural. The clearance notches 28 provide space for the support portion 24 to bend and avoid the limiting frame 11, allowing the support frame 4 to smoothly assist the patient in turning over from a side-lying position under the action of the airbag 3.

[0049] like Figure 9As shown, the bottom of the connecting frame 2 is provided with a positioning seat 29, which is engaged with the traction bed 1. It can be understood that the bed board of the traction bed 1 is provided with a slot that engages with the positioning seat 29, so that a stable connection is formed between the connecting frame 2 and the traction bed 1, ensuring the safety and reliability of the patient during traction treatment and body position adjustment.

[0050] The connecting part includes a flat plate and two arc-shaped parts. Arc-shaped openings 12 are respectively connected to both sides of the flat plate and are formed on the arc-shaped parts. Guide grooves 27 are formed on the arc-shaped parts, and guide parts 26 are slidably connected to the inner wall of the arc-shaped parts through the guide grooves 27. The guide parts 26 are arc-shaped and conform to the contour of the arc-shaped parts.

[0051] The working process of the supine lumbar spine rehabilitation traction device provided by this invention is as follows:

[0052] In the above scheme, when in use, medical staff place the connecting frame 2 on the traction bed 1, so that the positioning seat 29 engages with the slot. Then, the medical staff holds the handle 15 of the abutment frame 13 and presses the arc-shaped part 17 of the abutment frame 13 against the side wall of the connecting frame 2. The abutment part 16 passes through the through-hole 12 and abuts against the connection between the first sliding part 21 and the connecting part 22, and tightens the limiting pin 14 to achieve effective positioning of the connecting frame 2. The patient lies on the support frame 4 at the top of the connecting frame 2. The first limiting part 18, the fitting part 19, and the second limiting part 20 on the limiting frame 11 fit against the external oblique muscles, tensor fasciae latae, and vastus lateralis muscles on both sides of the patient, respectively. With the wearing of the strap 30, the lower body of the patient is effectively limited. When the medical staff increases the traction force according to the doctor's orders, the position of the upper body of the patient and the abutment frame 13 is relatively fixed. The connecting frame 2 and the support frame 4 on it drive the lower body of the patient to move synchronously with the movement of the bed board. The abutment part 16 slides in the opening 12. As the traction force increases, the abutment part 16 abuts against the connection between the first sliding part 21 and the connecting part 22, thereby tightening the first limiting part 18 and the second limiting part 20 inward. This allows the limiting frame 11 to increase the binding force on the patient's body as the traction force increases, avoiding damage to the patient caused by excessive tightening. After traction therapy is completed, the traction bed 1 is reset, and medical staff open the straps 30. Depending on the patient's position, the small airbags on one side of the airbag 3 inflate, causing the support frame 4 to bend under the pressure of the small airbags. This assists the patient in getting up from their side after treatment, effectively reducing the strain on the lower back and ensuring the traction effect. The airbag 3 pushes the support frame 4 to gradually change the patient's position, allowing for a more stable adjustment of blood circulation in different parts of the body. This effectively avoids uneven redistribution of blood due to rapid changes in position, reducing the likelihood of dizziness when the patient gets up after traction therapy and ensuring patient safety.

[0053] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
