Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic nursing, in particular to a portable orthopedic nursing crutch. Background Art

[0002] With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while trauma caused by traffic accidents has increased significantly. Crutches are an important medical rehabilitation aid.

[0003] Crutches in the prior art are commonly used auxiliary rehabilitation nursing equipment for people with leg fractures, but most crutches do not have a portable adjustment mechanism. When used by patients of different body sizes, they often cannot meet the needs of patients. When patients are tired of using them, they cannot provide support for the patients' legs, which is not conducive to patients' use. Utility Model Content

[0004] The utility model aims to provide a portable orthopedic nursing crutch which is more convenient to use.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A portable orthopedic nursing crutch comprises a load-bearing rod and an axillary support plate, wherein a mounting groove A is provided at the bottom of the load-bearing rod, a mounting groove B is provided at one side of the load-bearing rod, and a threaded hole is provided at the load-bearing rod near the mounting groove A; an extension rod is telescopically installed in the mounting groove A, threaded holes are provided on the extension rod at equal intervals, and the extension rod is fixed in the mounting groove A by means of a screw passing through the threaded hole mounting hole and extending into the threaded hole; a hand grip arm assembly is provided on the load-bearing rod, and the hand grip arm assembly is used to adjust the actual support length of the crutch; a support leg assembly is provided at the bottom of the load-bearing rod, and the support leg assembly is used to place the patient's calf; an anti-skid assembly is provided at the bottom of the extension rod, and the anti-skid assembly is used to improve the stability of the crutch; the axillary support plate is installed on the top of the load-bearing rod through a mounting block.

[0007] It can be seen that the user adjusts the total length of the load-bearing rod and the extension rod in advance to adapt to users with larger body sizes, and then places the armpit support plate at the armpit and supports the handgrip arm assembly with hands. When users with smaller body sizes need adjustment, the distance between the handgrip arm and the armpit support plate can be adjusted by adjusting the upper and lower positions of the handgrip arm assembly. The support leg assembly can provide support for the user's legs and relieve the shaking of the user's legs, so that the user's legs can rest without having to bend and curl up for a long time, thereby reducing the discomfort of the user's legs curled up for a long time. The anti-slip assembly can increase the contact area with the ground, play a further anti-slip role, improve the stability of the overall device, and provide greater safety.

[0008] Furthermore, the hand-grip arm assembly includes a rack, a sliding sleeve, a gripping rod, a guide rod, a pull rod, a tooth block and a tensioning spring; a rack is vertically installed in the installation groove B, the sliding sleeve is sleeved on the outer side of the load-bearing rod, and the gripping rod is fixedly connected to one side of the sliding sleeve; a guide rod is movably installed on the side of the sliding sleeve away from the gripping rod, a pull rod is installed on the outer end of the guide rod located at the sliding sleeve, and a tooth block is installed on the inner end of the guide rod located at the sliding sleeve, and the tooth block is meshed with the rack gear; the pull rod is installed between the tooth block and the inner wall of the sliding sleeve.

[0009] When users of different body shapes need to adjust the position of the hand-grip arm assembly, the user can hold and pull the pull rod outward with one hand to drive the tooth block to move outward, and hold and move the grip rod up and down with the other hand to adjust the height of the hand-grip arm assembly. When it is adjusted to a suitable position, the pull rod is released, and the guide rod and the tooth block are reset under the action of the tension spring. At this time, the gears of the tooth block and the screw rod form a clamping state to achieve a fixing effect, thereby completing the distance adjustment and fixation between the hand-grip arm assembly and the armpit support plate to meet the needs of users of different heights and body shapes, and having higher applicability.

[0010] Furthermore, the supporting leg assembly includes a mounting piece, a fixing rod, a connecting piece, a torsion spring and a supporting block; the mounting piece is installed on the load-bearing rod near the bottom, the fixing rod is installed on one side of the mounting piece, and the supporting block is movably installed on the fixing rod through the connecting piece; a torsion spring is connected between the connecting piece and the mounting piece, and the torsion spring is sleeved on the fixing rod.

[0011] When the user's legs need a rest, the legs can be placed on the support block and slightly shaken to drive the support block to shake, thereby achieving the effect of relaxing the legs. By using the support leg assembly, not only can the user's legs be supported when the user needs a rest, but the shaking can also have a relieving effect, thereby preventing the user's legs from being too tired due to long-term curling up and reducing the user's discomfort.

[0012] Furthermore, the anti-slip component includes a mounting base, a center column, a support rod and a bottom block; the mounting base is installed at the bottom of the extension rod, and the center column is installed at the center position of the lower surface of the mounting base; the support rods are installed in an array around the center column with the center column as the center, and the bottom block is installed on the contact surface between the support rods and the ground.

[0013] Compared to the original single extension pole bottom, the addition of a center column and support pole is more stable, avoiding the situation where unstable support affects use during use.

[0014] Furthermore, anti-skid bumps are installed on the bottom of the bottom block and the bottom of the center column.

[0015] The anti-slip protrusions can further increase the friction with the ground and prevent slipping.

[0016] Furthermore, elastic rubber pads are installed on the contact surfaces of the armpit support plate, the grip rod and the support block with the patient's limbs, and non-slip soft pads are provided on the elastic rubber pads.

[0017] The elastic rubber pads can provide softer support for the user's armpits, palms and legs, reducing the discomfort caused to the user's armpits, hands and legs by the hard armpit supports, grips and support blocks. The non-slip pads can provide friction to avoid slipping. BRIEF DESCRIPTION OF THE DRAWINGS
