Technical Field

[0001] This utility model relates to the technical field of medical equipment, and in particular to a handrail for a medical device. Background Technology

[0002] In modern healthcare systems, medical handrails serve as fundamental equipment to ensure patient safety and aid in rehabilitation, and are widely used in hospital wards, nursing homes, and community rehabilitation centers. They provide stable support for post-operative patients, elderly people with mobility issues, and other groups, and are important tools for reducing the risk of accidental falls and improving patients' autonomy.

[0003] However, existing medical handrail devices have the following shortcomings in practical use: With the development of rehabilitation medicine, the demand for precise and personalized rehabilitation training is constantly increasing. During standing balance training and upper and lower limb strength recovery training, different patients require significantly different handrail support angles due to differences in injury sites and rehabilitation progress. Fixed-angle handrails cannot be flexibly adjusted, resulting in some patients not receiving effective support during training, affecting the rehabilitation training effect, and potentially even causing secondary injuries due to incorrect force application postures. In view of this, the medical handrail device proposed in this application is presented. Utility Model Content

[0032] like Figures 1 to 5 As shown, in one embodiment, a medical device armrest 1 includes a housing 10 and an adjustment assembly. The housing 10 has a sliding cavity 11. The adjustment assembly includes an insert 20, a handle 21, a locking block 22, and a locking element 23. The handle 21 passes through the housing 10. The insert 20 is disposed on the handle 21 and slides coaxially within the sliding cavity 11. The locking block 22 is coaxially disposed on the inner bottom wall of the sliding cavity 11. The insert 20 has a plurality of teeth 201, and each tooth 201 is equidistantly distributed along the circumferential direction of the outer surface of the insert 20. The block 22 has several toothed grooves 220, and each toothed groove 220 is equidistantly distributed along the circumferential direction of the inner sidewall of the block 22. The support rod 21 drives the insertion block 20 to approach the block 22, so that each tooth 201 is inserted into each toothed groove 220 in a corresponding manner, so that the rotation angle of the support rod 21 relative to the housing 10 is adjustable. The locking member 23 is slidably disposed on the housing 10 perpendicular to the opening direction of the sliding cavity 11. The support rod 21 has an annular groove 2110, and the locking member 23 is inserted into the annular groove 2110 to restrict the support rod 21 from driving the insertion block 20 away from the block 22.

[0033] It should be noted that the housing 10 is used to mount on the equipment, for example, the housing 10 is screwed onto the equipment. The sliding cavity 11 has a cylindrical structure and extends from one end of the housing 10 to the other end. Furthermore, the housing 10 also has a through hole, which is coaxial with the sliding cavity 11 and communicates with one end face of both the sliding cavity 11 and the housing 10, allowing one end of the sliding cavity 11 to communicate with the external environment through the through hole. Furthermore, one end of the support rod 21 slides coaxially within the sliding cavity 11, while the other end of the support rod 21 extends through the through hole relative to the sliding cavity 11 to the external environment. The insert block 20 has a cylindrical structure and is coaxially disposed on the end of the support rod 21 located within the sliding cavity 11, allowing the support rod 21 to drive the insert block 20 to slide coaxially within the sliding cavity 11. The outer wall of the insert block 20 is provided with a number of teeth 201, each tooth 201 being equidistantly distributed along the circumferential direction with the axis of the insert block 20 as the center. Further, the locking block 22 is a cylindrical structure, coaxially disposed on the inner bottom wall of the sliding cavity 11 away from the through hole. The locking block 22 has a through hole, coaxially penetrating both ends of the locking block 22, and the diameter of the through hole is larger than the diameter of the insert block 20. Each tooth groove 220 is equidistantly distributed along the circumferential direction of the inner wall with the axis of the locking block 22 as the center. It should be noted that the number of teeth 201 is the same as the number of tooth grooves 220. Thus, when the handrail 21 drives the insert block 20 to slide along the axial direction of the sliding cavity 11 and approach the locking block 22, each tooth 201 on the insert block 20 is engaged with each groove 220 on the locking block 22. Specifically, when a tooth 201 on the insert block 20 rotates along the axial direction of the insert block 20 to engage with any groove 220 on the locking block 22, the angle at which the insert block 20 drives the handrail 21 to rotate about the axis of the locking block 22 is adjustable, thereby making the rotation angle of the handrail 21 relative to the housing 10 adjustable. Furthermore, the locking member 23 is slidably disposed on the housing 10 perpendicular to the opening direction of the sliding cavity 11, so that the locking member 23 can slide into or slide away from the sliding cavity 11 relative to the housing 10. An annular groove 2110 is provided on the outer wall of the handrail 21, and the annular groove 2110 is opened along the circumferential direction of the handrail 21. When the support bar 21 drives the insertion block 20 to engage with the locking block 22, the annular groove 2110 aligns with the sliding direction of the locking member 23. This allows the locking member 23 to slide into the annular groove 2110 relative to the housing 10. Since the sliding direction of the locking member 23 is perpendicular to the opening direction of the sliding cavity 11, after the locking member 23 slides into the annular groove 2110, the support bar 21 cannot drive the insertion block 20 to slide away from the locking block 22 along the opening direction of the sliding cavity 11. Consequently, each tooth 201 cannot disengage from each tooth groove 220, thus fixing the angle of rotation of the support bar 21 relative to the housing 10 and preventing the support bar 21 from sliding. In this way, during rehabilitation training, the patient can adjust the appropriate support angle according to the injured area to improve the effectiveness of the rehabilitation training.

[0034] like Figures 2 to 4 As shown, in one embodiment, the handrail 21 includes a rod body 210 and a slider 211. The slider 211 slides in the sliding cavity 11, and both ends of the slider 211 are connected to the rod body 210 and the insert block 20, respectively. An annular groove 2110 is formed on the slider 211.

[0035] It should be noted that the slider 211 has a cylindrical structure and slides adaptably within the sliding cavity 11. The rod 210 is coaxially disposed on one end of the slider 211; for example, the rod 210 and the slider 211 are integrally formed. The other end of the rod 210 extends through a through hole to be located in the external environment. The insert 20 is coaxially disposed on the end of the slider 211 away from the rod 210. In this way, the patient can use the rod 210 located in the external environment to move the insert 20 relative to the sliding cavity 11 closer to or further away from the locking block 22, so that each tooth 201 is inserted into the corresponding tooth socket 220. Furthermore, the annular groove 2110 is formed circumferentially on the outer wall of the slider 211 with the axis of the slider 211 as the center.

[0036] like Figure 2 As shown, in one embodiment, the end of the rod 210 away from the slider 211 has an S-shaped structure.

[0037] It should be noted that when a person's hand is in a normal fist position, the axis of the fist is perpendicular to the forearm in a natural state. Therefore, the end of the lever 210 furthest from the slider 211 has an S-shaped structure, and the part of the lever 210 furthest from the slider 211 is perpendicular to the part of the lever 210 closest to the slider 211. This allows the patient to grip the lever 210 naturally in a fist position, enabling the handrail 21 to better support the patient.

[0038] like Figures 4 to 5 As shown, in one embodiment, the outer diameter of the slider 211 is adapted to the inner diameter of the slide cavity 11.

[0039] It should be noted that the outer diameter of the slider 211 is adapted to the inner diameter of the slide cavity 11, so that the slider 211 can slide along the axial direction against the inner wall of the slide cavity 11, thereby enabling the rod 210 and the insert block 20, which are coaxially mounted on the slider 211, to also slide coaxially relative to the slide cavity 11.

[0040] like Figure 2 As shown, in one embodiment, the adjustment assembly further includes a push spring 24, which is sleeved on the rod 210. The two ends of the push spring 24 abut against the inner bottom wall of the slide cavity 11 and the slider 211, respectively.

[0041] It should be noted that the push spring 24 is sleeved on the end of the rod 210 near the slider 211, and the push spring 24 is located inside the slide cavity 11. Furthermore, the maximum diameter of the push spring 24 is smaller than the inner diameter of the slide cavity 11, allowing the push spring 24 to be located within the slide cavity 11. The two ends of the push spring 24 abut against the end of the slider 211 near the rod 210 and the inner bottom wall of the slide cavity 11 away from the locking block 22, respectively, causing the push spring 24 to push the slider 211, thus moving the insert block 20 closer to the locking block 22. In this way, when the patient holds the rod 210, it moves the insert block 20 away from the locking block 22, simultaneously causing the rod 210 to move the slider 211 and compress the push spring 24. When the patient rotates the lever 210 to engage a tooth 201 with any slot 220 to adjust the angle, the patient does not need to hold the lever 210 to push the insert 20 and the locking block 22 into place. Instead, the push spring 24 pushes the slider 211, causing the insert 20 and the locking block 22 to engage. This reduces the patient's operating movements and improves ease of use.

[0042] like Figures 4 to 5 As shown, in one embodiment, the housing 10 is further provided with a side cavity 12, the opening direction of the side cavity 12 is perpendicular to the opening direction of the slide cavity 11, and the side cavity 12 is connected to the slide cavity 11, and the locking member 23 is adapted to slide in the side cavity 12.

[0043] It should be noted that one end of the side cavity 12 is connected to the sliding cavity 11, and the locking member 23 slides adaptedly within the side cavity 12. In this way, one end of the locking member 23 can slide perpendicularly into the sliding cavity 11 relative to the side cavity 12.

[0044] like Figures 2 to 4 As shown, in one embodiment, the locking member 23 includes a top block 230, a top post 231, and a locking spring 232. The top block 230 slides in the side cavity 12, the top post 231 is disposed on the top block 230, and the locking spring 232 is sleeved on the top post 231. The two ends of the locking spring 232 abut against the top block 230 and an inner bottom wall of the side cavity 12, respectively. The top block 230 is inserted into the annular groove 2110.

[0045] It should be noted that the top block 230 slides adaptably within the side cavity 12, one end of the top post 231 is located on the end of the top block 230 away from the sliding cavity 11, and the other end of the top post 231 extends through the inner bottom wall of the side cavity 12 away from the sliding cavity 11 and out to the external environment relative to the housing 10. The locking spring 232 is sleeved on the top post 231 and is located within the side cavity 12, so that both ends of the locking spring 232 abut against the top block 230 and the inner bottom wall of the side cavity 12 away from the sliding cavity 11, respectively, thereby causing the locking spring 232 to push the top block 230 to slide vertically into the sliding cavity 11 relative to the side cavity 12. Thus, under the continuous pushing force of the locking spring 232, the top block 230 extends vertically into the sliding cavity 11 relative to the side cavity 12 and engages with the annular groove 2110 on the slider 211. This prevents the slider 211 from sliding relative to the sliding cavity 11 to drive the insert block 20 to slide closer to or away from the locking block 22, thereby making the rotation angle of the handle 21 unadjustable.

[0046] like Figures 2 to 4 As shown, in one embodiment, the top block 230 has an arc-shaped surface 2301.

[0047] It should be noted that because the annular groove 2110 is opened along the circumference of the slider 211, the inner bottom wall of the annular groove 2110 has a cylindrical structure, and each radial direction has an arc-shaped structure. The top block 230 slides perpendicularly into the annular groove 2110 relative to the axis of the slider 211. This means that when the end face of the top block 230 away from the top post 231 contacts, the end face of the top block 230 near the annular groove 2110 cannot completely abut against the circumferential inner bottom wall of the annular groove 2110, resulting in a loose engagement between the top block 230 and the annular groove 2110. Therefore, the end face of the top block 230 near the annular groove 2110 has an arc-shaped portion 2301, with one end extending to the other to form a circle with a diameter matching the diameter of the inner bottom wall of the annular groove 2110. This allows the top block 230 to fit snugly into the annular groove 2110, thereby improving the stability of the engagement.

[0048] like Figure 2 As shown, in one embodiment, the medical device armrest 1 further includes an outer shell 30 and an inner shell 40, which are interlocked to enclose the rod body 210.

[0049] It should be noted that the outer shell 30 and the inner shell 40 are interlocked to cover the part of the rod 210 that extends into the external environment relative to the shell 10, making the part of the rod 210 in the external environment relatively thicker to increase the comfort of the patient's grip.

[0050] like Figures 1 to 2 As shown, in one embodiment, both the outer shell 30 and the inner shell 40 are S-shaped structures.

[0051] It should be noted that, because the portion of the rod 210 located in the external environment has an S-shaped structure, the outer shell 30 and inner shell 40 that interlock to enclose the rod 210 also have an S-shaped structure, so that the outer shell 30 and inner shell 40 can fit better against the rod 210. Furthermore, several screw holes are provided on the portion of the rod 210 located in the external environment, and the outer shell 30 and inner shell 40 are both screwed together and fixed by screws passing through the screw holes.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
