Description

Technical Field

[0001] This utility model relates to the field of fall protection equipment technology, and in particular to a fall protection device for osteoporosis patients. Background Technology

[0002] Osteoporosis is an orthopedic disease characterized by bone pain and a high risk of fractures. It affects not only the elderly but also teenagers, though it is more common in the elderly. For patients with osteoporosis, walking is beneficial to promote blood circulation. However, patients with osteoporosis often have unsteady gaits, especially the elderly, making them prone to falls. Therefore, fall protection devices are needed to assist them with walking exercises.

[0003] Patent application CN202320023949.8 discloses an osteoporosis fall prevention device that can fix the patient's upper body and the device, facilitating upright walking. Simultaneously, the wearable vest used to fix the patient's upper body can rise and fall with the support rods through a lifting and locking structure, making it easier for the patient to bend over. Combined with a support plate for supporting the patient's buttocks, it allows the patient to sit down and rest at any time, improving patient comfort and largely meeting the needs for walking and resting. However, this fall prevention device does not fully consider the practicality issues arising from the different body shapes of patients. In other words, the fixed distance between the two support rods is too wide for smaller patients, making it difficult to support them and potentially causing them to slip off the vest; for larger patients, the distance is too small, restricting their movement space and making walking and sitting difficult. Therefore, the existing fall prevention device still has some shortcomings and needs further improvement. Utility Model Content

[0004] In view of the above, it is necessary to provide a fall protection device for osteoporosis patients that can adjust the activity space according to the patient's body shape, making it easier for patients of different body types to exercise and improving the range of adaptability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fall protection device for osteoporosis patients includes two base plates, each base plate having a caster wheel at its bottom and a support bottom rod and a support top rod at its top. The support top rod is movably sleeved on the upper part of the support bottom rod and has a locking mechanism to prevent it from sliding relative to the support bottom rod. The support top rods on the two base plates are connected by a wearable vest and a back support rod.

[0007] The wearable vest is detachably connected to each support rod; the back support rod surrounds the back of the wearable vest and includes a back support rod one and a back support rod two. One end of the back support rod one is connected to a support rod on a base plate, and one end of the back support rod two is connected to a support rod on another base plate. The other end of the back support rod two is slidably fitted with the other end of the back support rod one, and a locking mechanism is provided at the fitting point to prevent the two from sliding relative to each other.

[0008] A seat plate is rotatably mounted on the lower section of a support rod on a base plate. The seat plate is attached to the support rod by rotation relative to the support rod or is set perpendicular to the support rod. The end of the seat plate not connected to the support rod is detachably connected to a support rod on another base plate. The seat plate is a telescopic structure.

[0009] Preferably, the wearable vest has connecting channels on both opposite sides, and the connecting channels are arranged along the length of the wearable vest; an inverted L-shaped plate is provided on the side wall of the support rod facing the wearable vest, the end of the L-shaped horizontal edge of the plate that is not connected to the L-shaped vertical edge is connected to the support rod, the L-shaped vertical edge of the plate is spaced apart from the support rod, the wearable vest is connected to the support rod by passing through the connecting channel through the L-shaped vertical edge of the plate, and the wearable vest has a connector at the upper end of the connecting channel for detachably connecting the L-shaped horizontal edge of the plate.

[0010] Preferably, the connector is a soft strip structure, one end of which is connected to the wearable vest, and the other end is detachably connected to the connecting plate via a buckle assembly.

[0011] Preferably, the L-shaped vertical edge of the card plate can also be detachably connected to a wearable vest.

[0012] Preferably, both the first and second rear support rods have arc-shaped segments and straight segments, with the arc-shaped segments connected to the top support rod and the straight segments interlocking with each other.

[0013] Preferably, the locking mechanism includes locking holes and locking rods. In the straight segments of the first and second rear support rods, multiple locking holes are provided on the straight segment on the inner side of the sleeve. The locking holes are spaced apart along the length of the straight segment. A locking rod is provided at one end of the straight segment on the outer side of the sleeve. This end is not connected to the arc segment. The locking rod is movably inserted into the straight segment in which it is located, with one end located on the outer side of the straight segment and the other end located on the inner side of the straight segment. The locking hole is inserted when the locking holes on the straight segment on the inner side of the sleeve are aligned.

[0014] Preferably, the locking rod is threaded into the straight segment in which it is located or slidably inserted into the straight segment in which it is located. If it is slidably inserted, a return spring is sleeved on the locking rod. The return spring connects the locking rod and the straight segment in which the locking rod is located. In the natural state of the return spring, the other end of the locking rod is located inside the straight segment in which the locking rod is located.

[0015] Preferably, the seat includes a first seat plate and a second seat plate.

The U-shaped clip can be slidably engaged with or disengaged from the overlapping block by the U-shaped opening.

[0017] Preferably, the second support plate is also detachably connected to the support base rod connected to the first support plate or the support top rod on the same side by means of magnetic attraction.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The fall protection device of this utility model uses a wearable vest to limit the upper body of the patient. The wearable vest is detachable and can be replaced with vests of different sizes, so that the vest fits the patient's body shape better and the wearing effect is better. The sliding design of the back support rod connecting the two support rods allows the spacing of the support rods supporting the patient on both sides to be adjusted, which means that the patient's movement space is adjustable. In this way, with the wearable vest of the appropriate size, it can provide good support and protection for the patient without affecting the patient's movement, making it convenient for the patient to walk and sit down, greatly improving the fall protection effect, and making this device suitable for more patients of different body types, with a wider range of applications and better practicality.

[0020] 2. The seat of this utility model is convenient for patients to sit down and rest. Its telescopic design can adjust the length of the seat to adapt to the distance between the two supporting top plates, so as to meet the needs of patients of different body types. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0030] Please see Figure 1-6In a preferred embodiment of this utility model, a fall prevention device for osteoporosis patients includes two base plates 1. Each base plate 1 has a movable wheel 2 at its bottom and a supporting bottom rod 3 and a supporting top rod 4 at its top. The supporting top rod 4 is movably sleeved on the upper part of the supporting bottom rod 3, and a locking mechanism 8 is provided on the supporting top rod 4 to prevent the supporting top rod 4 from sliding relative to the supporting bottom rod 3. The locking mechanism 8 can be used to lock the supporting top rod 4 after the height is adjusted. The locking mechanism 8 has the functions of unlocking and locking. Its specific structure can adopt existing structures, such as the locking mechanism 8 used in the osteoporosis fall prevention device given in the patent document with application number CN202320023949.8 mentioned in the background art. Of course, other structures are also possible. As described in this embodiment, the locking mechanism 8 includes several locking holes 8.1 and locking rods 8.2. The locking holes 8.1 are spaced apart on the support base rod 3 and arranged sequentially along the height direction of the support base rod 3. The locking rod 8.2 is installed on the end of the support top rod 4 facing the base plate 1, and a locking spring (not shown) is sleeved on it. The locking spring is connected to the locking rod 8.2 and the support top rod 4 respectively. One end of the locking rod 8.2 is located outside the support top rod 4, and the other end movably passes through the support top rod 4. This other end abuts against the rod wall of the support base rod 3 in its natural state or is inserted into the locking hole 8.1 when it is directly opposite the locking spring, thereby achieving locking. To unlock, simply pull the locking rod 8.2 by pulling the end of the locking rod 8.2 located outside the support top rod 4 to disengage it from the locking hole 8.1. To facilitate pulling the locking rod 8.2, an operating handle is provided at the end of the locking rod 8.2 located outside the support top rod 4. In addition, an operating handle is also provided at this end of the locking rod 8.2. A limiting rod 8.3 is vertically positioned to lock the rod 8.2. A limiting groove 8.4 is formed on the outer wall of the supporting top rod 4. The limiting rod 8.3 is embedded in the limiting groove 8.4 when the locking rod 8.2 is inserted into the locking hole 8.1. The limiting rod 8.3 also disengages from the limiting groove 8.4 when the locking rod 8.2 disengages from the locking hole 8.1. Furthermore, the limiting rod 8.2 is offset from the limiting groove 8.4 by relative rotation on the supporting top rod 4. At this time, the limiting rod 8.3 abuts against the supporting top rod 4 under the action of the locking spring. The outer wall of the locking rod 8.2 restricts its insertion into the locking hole 8.1 when it is directly aligned with the locking hole 8.1. Only when the limiting rod 8.3 is directly aligned with the limiting groove 8.4 can the locking hole 8.1 be inserted. This structure facilitates height adjustment of the support rod 4 by limiting the position. Thus, during the entire height adjustment process, it is unnecessary to continuously pull the operating handles on both sides; simply rotating the locking rod 8.2 at the beginning and end of the adjustment is sufficient. For details on the unlocking and locking structures, see [link to unlocking and locking structure]. Figure 3 ,in, Figure 3The locking mechanism 8 at the left support rod 4 is in the locked state, and the locking mechanism 8 at the right support rod 4 is in the unlocked state.

[0031] In this invention, the support rods 4 on the two base plates 1 are connected by a wearable vest 5 and a back support rod 6. The wearable vest 5 is easy for the patient to wear, thereby fixing the patient's upper body. The back support rod 6 is used to connect the two support rods 4, so that the two support rods 4 can better support the patient and facilitate the patient's walking exercise. The wearable vest 5 and each support rod 4 are detachably connected. The back support rod 6 surrounds the back of the wearable vest 5 and includes a first back support rod 6.1 and a second back support rod 6.2. One end of the first back support rod 6.1 is connected to the support rod 4 on one base plate 1, and one end of the second back support rod 6.2 is connected to the support rod 4 on the other base plate 1. The other end of the second back support rod 6.2 is slidably fitted with the other end of the first back support rod 6.1, and a locking mechanism is provided at the fitting point to prevent relative sliding between the two.

[0032] That is, the wearable vest 5 of this utility model is detachable and can be replaced for washing. It can also be replaced with vests 5 of different sizes to facilitate wearing by patients of different body types, avoiding the discomfort and unsatisfactory use caused by wearing it too tightly or too loosely. This reduces the risk of slipping and falling due to looseness and the inconvenience of wearing it too tightly. In this embodiment, the detachable method of the wearable vest 5 is as follows: connecting channels 5.1 are provided on both opposite sides of the wearable vest 5, and the connecting channels 5.1 are arranged along the length of the wearable vest 5; an inverted L-shaped clamping plate 4.1 is provided on the side wall of the support rod 4 facing the wearable vest 5. The end of the L-shaped horizontal side of the clamping plate 4.1 that is not connected to the L-shaped vertical side is connected to the support rod 4. The L-shaped vertical side of the clamping plate 4.1 is spaced apart from the support rod 4. The wearable vest 5 is passed through the L-shaped vertical side of the clamping plate 4.1. The wearable vest 5 is connected to the support rod 4 via a connecting channel 5.1. At the upper end of the connecting channel 5.1, a connector 5.2 is provided for the L-shaped horizontal side of the detachable connecting plate 4.1. When the connector 5.2 is connected to the plate 4.1, the wearable vest 5 is fixed to the support rod 4 and cannot be detached downwards. When the connector 5.2 is not connected to the plate 4.1, the wearable vest 5 is not fixedly connected to the plate 4.1. By moving downwards to completely detach the connecting channel 5.1 from the plate 4.1, the wearable vest 5 can be removed from the support rod 4. In this embodiment, preferably, the connector 5.2 is a soft strip structure, with one end connected to the wearable vest 5 and the other end detachably connected to the connecting plate 4.1 via a button assembly. The button assembly can be a concealed button, a visible button, a button, or other button structure to improve the patient's comfort while walking. To improve the connection stability between the wearable vest 5 and the support rod 4, preferably, the L-shaped vertical edge of the card plate 4.1 can also be detachably connected to the wearable vest 5, specifically through a button assembly, Velcro assembly, or other means.

[0033] To complement the detachable design of the wearable vest 5 and meet the needs of patients with different body types, this invention also configures the back support rod 6 as two relatively sliding back support rods 6.1 and 6.2, thereby adjusting the distance between the two support rods 4, which in turn adjusts the patient's range of motion. Specifically, the relative sliding of the back support rods 6.1 and 6.2 allows adjustment of the overall length of the back support rod 6, thus changing the distance between the two support rods 4, which is then fixed by a locking mechanism. In this embodiment, both the back support rod 6.1 and 6.2 have arc-shaped and straight segments. The arc-shaped segments connect to the support rods 4, and the straight segments interlock. The length of the back support rod 6 is adjusted by the relative sliding of the straight segments, and the locking mechanism is located on the straight segments. Furthermore, the locking mechanism includes locking holes 6.4 and locking rods 6.3. In the straight segments of the first rear support rod 6.1 and the second rear support rod 6.2, multiple locking holes 6.4 are provided on the straight segment on the inner side of the sleeve. The locking holes 6.4 are spaced apart along the length of the straight segment. A locking rod 6.3 is provided at one end of the straight segment on the outer side of the sleeve; this end is not connected to the arc segment. The locking rod 6.3 is movably inserted into the straight segment it is located in, with one end on the outer side of the straight segment and the other end on the inner side. The locking holes 6.4 on the straight segment on the inner side of the sleeve are aligned, thereby preventing the first rear support rod 6.1 and the second rear support rod 6.2 from sliding relative to each other, thus locking them. Preferably, the locking rod 6.3 is threaded into the straight segment in which it is located or slidably inserted into the straight segment in which it is located. If it is slidably inserted, a return spring is sleeved on the locking rod 6.3. The return spring connects the locking rod 6.3 and the straight segment in which the locking rod 6.3 is located. In the natural state of the return spring, the other end of the locking rod 6.3 is located inside the straight segment in which the locking rod 6.3 is located.

[0034] In this invention, a seat 7 is rotatably mounted on the lower section of a support rod 3 on a base plate 1. The seat 7 is attached to or perpendicular to the support rod 3 by rotating relative to it. One end of the seat 7, not connected to the support rod 3, is detachably connected to a support rod 3 on another base plate 1. The seat 7 is a telescopic structure. That is, the seat 7 of this invention can be folded up and used by flipping, facilitating rest for patients during walking training without affecting their walking practice. Furthermore, the telescopic design of the seat 7, combined with the adjustable length of the back support rod 6, allows for adjustable spacing between the two support rods 4, thus meeting the needs of patients of different body types. In this embodiment, the seat 7 includes a first seat plate 7.1 and a second seat plate 7.2. One end of the first seat plate 7.1 is hinged to a support rod 3 on a base plate 1, and the other end is slidably fitted onto one end of the second seat plate 7.2. An anti-slip lock 7.3 is installed at the fitting to prevent relative sliding, thereby fixing the length of the seat 7. The specific structure of the anti-slip lock 7.3 can refer to the locking structure and fastening mechanism described above, or it can refer to the retractable fixing method of a folding umbrella shaft. The second seat plate 7.2 has an overlapping part 7.4 at the other end, and the supporting bottom rod 3 on the other base plate 1 is provided with a mounting block 7.5. The second seat plate 7.2 is detachably connected to the supporting bottom rod 3 of the other base plate 1 by overlapping the overlapping part 7.4 on the top surface of the mounting block 7.5. That is, the overlapping part 7.4 of the second seat plate 7.2 can be flipped upward to be above the first seat plate 7.1, and flipped downward to be placed on the mounting block 7.5, so that the patient can sit down. When the patient needs to put away the seat plate 7, he can simply flip the seat plate 7 upward. Preferably, to improve the stability of the seat 7 resting on the support block 7.5, a U-shaped latch 7.6 is slidably provided on the end of the overlapping part 7.4 away from the first seat plate 7.1. One U-shaped vertical edge of the U-shaped latch 7.6 is slidably connected to the overlapping part 7.4. The U-shaped latch 7.6 can be slid to engage or disengage from the support block 7.5. When the U-shaped opening engages with the support block 7.5, the seat 7 cannot be flipped upwards. Only by disengaging the U-shaped opening of the U-shaped latch 7.6 from the support block 7.5 can the seat 7 be flipped. Because the U-shaped latch 7.6 is slidably provided, the patient only needs to pull it horizontally to unlock and lock, making operation convenient. Furthermore, considering that the seat 7 may flip downwards when folded up, thus affecting the storage effect and the possibility of accidental opening, this embodiment also detachably connects the second seat plate 7.2 to the support base rod 3 connected to the first seat plate 7.1 or the support top rod 4 on the same side via magnetic attraction.For this type of magnetic attraction, magnetic attraction can be achieved by two dissimilar magnets attracting each other, or a magnetic attraction structure composed of a magnetic device and a metal sheet (not shown in the figure) as used in the patent document with application number 201920401370.4 can be used. In this case, the magnetic device is installed on the second support plate 7.2 and includes a non-magnetic body, two magnetic bodies, a soft magnet, and a strip magnet metal sheet laid on the side wall of the support top rod 4 and the support bottom rod 3.

[0035] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
