Technical Field

[0001] This utility model relates to the field of nursing support technology, specifically an adjustable nursing support. Background Technology

[0002] Nursing braces, depending on their type and purpose, mainly include external fixation braces for arm fractures, upper limb abduction braces, elbow joint braces, and vascular stents. Among them, external fixation braces for arm fractures, also known as braces, are fixation devices placed outside the body. They are mainly composed of metal strips, bandages, etc., and play a role in stabilizing and supporting the injured area, protecting and fixing the injured area, and promoting recovery.

[0003] Currently, the external fixation device for arm fractures mainly consists of two struts connected by a knob-type structure and an arm-holding strap mounted on the strut. The arm-holding strap is usually fixed to the side wall of the strut. However, due to differences in body shape, the length of the upper and lower arm of patients may vary. The fixed arm-holding strap cannot be adjusted to fit the length of the patient's arm.

[0004] Therefore, an adjustable nursing support is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that arm-holding straps are mostly fixed to the side wall of the support rod, while patients have different arm lengths due to differences in body shape, the fixed arm-holding straps cannot be adjusted to adapt to the patient's arm length, an adjustable nursing support is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The adjustable nursing support of this utility model includes two fixed supports arranged symmetrically. The intersecting ends of the two fixed supports are connected by a knob-type structure. A card slot is opened on the side wall of the fixed support away from the knob-type structure. An adjusting card is slidably installed between the inner walls of the card slot. A limit component is provided on the side wall of the adjusting card near the knob-type structure. A first arm strap is installed on both ends of the side wall of one adjusting card. A second arm strap is installed on the side wall of the other adjusting card near the end of the first arm strap. A wrist fixation component is provided on the other end of the side wall of the other adjusting card.

[0007] Preferably, the limiting component includes a limiting plate, and the side wall of the limiting plate is provided with through holes near both ends. A fixed guide rod is slidably installed between the inner walls of the through holes, and one end of the fixed guide rod is perpendicularly fixed to the side wall of the adjusting plate.

[0008] Preferably, the limiting plate is fixedly connected to a limiting protrusion near the side wall where the adjusting plate is located, and the limiting protrusion can engage with the circular groove on the side wall of the fixed bracket.

[0009] Preferably, the other end of the fixed guide rod is fixedly connected to a limiting plate, and a spring is slidably fitted on the outer wall of the fixed guide rod, the spring being located between the adjacent side walls of the limiting plate and the limiting clamping plate.

[0010] Preferably, the wrist fixation assembly includes an inclined wall base, the side wall of which is fixedly connected to the end of the adjustment plate away from the knob-type structure.

[0011] Preferably, the wall thickness of the inclined base gradually increases along the direction away from the knob-type structure.

[0012] Preferably, the inclined surface of the inclined wall base is provided with a slider rail, and a wrist strap slider is slidably installed between the inner walls of the slider rail.

[0013] Preferably, a limiting pin is fitted between the side wall through holes of the inclined base, and the limiting pin passes through the side wall through hole of the wrist strap slider.

[0014] The beneficial effects of this utility model are:

[0015] 1. In this utility model, the adjusting plate is installed through the plate groove opened on the side wall of the fixed bracket, and the first arm-holding strap, the second arm-holding strap and the wrist fixation component are respectively installed between the adjacent side walls of the two adjusting plates. This allows the device to adjust the arm-holding position of the first arm-holding strap, the second arm-holding strap and the wrist fixation component within a certain range according to the patient's arm length, thereby increasing the practicality of the device.

[0016] 2. In this utility model, the wrist fixation component is bound to the patient's wrist by a wrist-binding slider. The wrist-binding slider is slidably installed in the slider track. This allows the large gap between the wrist recess and the adjustment plate to be filled by sliding the wrist-binding slider after the forearm is bound to the second arm-holding strap near the joint, thus ensuring stable support of the arm by the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 4This utility model provides an adjustable nursing support, including two symmetrically arranged fixed supports 1. The intersecting ends of the two fixed supports 1 are connected by a knob-type structure 2. A locking groove 11 is formed on the side wall of the fixed support 1 away from the knob-type structure 2. An adjusting locking plate 3 is slidably installed between the inner walls of the locking groove 11. A limit component 4 is provided on the side wall of the adjusting plate 3 near the knob-type structure 2. A first arm-holding strap 31 is installed on both ends of the side wall of one adjusting plate 3, and a second arm-holding strap 32 is installed on the side wall of the other adjusting plate 3 near the end of the first arm-holding strap 31. A wrist fixation component 5 is provided on the other end of the side wall of the other adjusting plate 3. Under the action of the knob-type structure 2, the two fixed supports 1 are hinged to each other, and the relative angle between the two fixed supports 1 can be adjusted by adjusting the tightness of the knob-type structure 2 to adapt to changes in the bending degree between the patient's upper and lower arms. The fixed bracket 1 is installed with the adjusting plate 3 via the plate slide groove 11. The upper arm is bound between the adjacent side walls of the two adjusting plates 3 by two first arm-holding straps 31, and the forearm near the joint is bound by the second arm-holding strap 32. The wrist fixation component 5 can bind the forearm and wrist. The sliding of the adjusting plate 3 within the plate slide groove 11 allows the device to adjust the binding position between the first arm-holding strap 31, the second arm-holding strap 32, and the wrist fixation component 5 and the arm within a certain range according to the length of the patient's arm. The mutual sliding between the plate slide groove 11 and the adjusting plate 3 is limited by the limiting component 4.

[0027] like Figure 1 and Figure 3As shown, the limiting component 4 includes a limiting plate 41. Through holes 411 are provided on the sidewalls of the limiting plate 41 near both ends. A fixed guide rod 42 is slidably installed between the inner walls of the through holes 411. One end of the fixed guide rod 42 is perpendicularly fixed to the sidewall of the adjusting plate 3. A limiting protrusion 412 is fixed to the sidewall of the limiting plate 41 near the adjusting plate 3. The limiting protrusion 412 can engage with the circular groove on the sidewall of the fixed bracket 1. The other end of the fixed guide rod 42 is fixed to a limiting plate 421. A spring 43 is slidably fitted on the outer wall of the fixed guide rod 42. The spring 43 is located between the adjacent sidewalls of the limiting plate 421 and the limiting plate 41. The limiting plate 41 engages and slides with the fixed guide rod 42 fixed to the sidewall of the adjusting plate 3 through the through holes 411, thus enabling the adjusting plate 3 to install the limiting component 4. When the upper limit protrusion 412 of the limiting plate 41 engages with the side wall groove of the fixed bracket 1, the adjusting plate 3 in the plate slide groove 11 cannot be adjusted in relative position. At this time, the relative length of the fixed bracket 1 and the adjusting plate 3 is fixed. When the relative position of the adjusting plate 3 in the plate slide groove 11 needs to be adjusted, the limiting plate 41 needs to be pulled outward to overcome the elastic force of the spring 43 between the limiting plate 41 and the limiting plate 421. At this time, the limiting protrusion 412 disengages from the outer groove of the fixed bracket 1, and the adjusting plate 3 in the plate slide groove 11 can be adjusted in relative position. After the relative position of the adjusting plate 3 is adjusted, the external force on the limiting plate 41 is released, and the limiting protrusion 412 returns to engaging with the outer groove of the fixed bracket 1. The device limits the relative length between the fixed bracket 1 and the adjusting plate 3.

[0028] like Figure 1 and Figure 4 As shown, the wrist fixation assembly 5 includes an inclined base 51. The side wall of the inclined base 51 is fixedly connected to the end of the adjusting plate 3 away from the knob-type structure 2. The wall thickness of the inclined base 51 gradually increases along the direction away from the knob-type structure 2. A slider rail 511 is provided on the inclined surface of the inclined base 51. A wrist-binding slider 52 is slidably installed between the inner walls of the slider rail 511. A limit pin 53 is engaged between the through holes in the side wall of the inclined base 51. The limit pin 53 passes through the through hole in the side wall of the wrist-binding slider 52. The mutual fixation between the adjusting plate 3 and the wrist fixation assembly 5 is achieved through the mutual fixation between the side wall of the inclined base 51 and the adjusting plate 3. The inclined base 51 has a gradually increasing wall thickness along the direction away from the knob structure 2, which is adapted to the significant reduction in the dimension of the forearm and wrist. The inclined base 51 is used to install the wrist strap slider 52 through the opening of the slider rail 511. The wrist strap slider 52 can be tied to the patient's wrist strap through its outer strap. The wrist strap slider 52 can move under the limitation of the slider rail 511. After the second arm strap 32 is tied to the forearm, the relative position of the wrist strap slider 52 can be adjusted within a certain range according to the relative position of the wrist. The limiting pin 53 can lock and limit the relative position of the wrist strap slider 52 in the slider rail 511.

[0029] Working principle: Under the action of the knob-type structure 2, the two fixed supports 1 are hinged to each other, and the relative angle between the two fixed supports 1 can be adjusted by adjusting the tightness of the knob-type structure 2 to adapt to changes in the bending degree between the patient's upper and lower arms; the fixed supports 1 are installed with the adjusting plate 3 through the plate slide groove 11, and the upper arm is bound by two first arm-holding straps 31 between the adjacent side walls of the two adjusting plate 3, and the forearm is bound by the second arm-holding strap 32 near the joint; the wrist fixation component 5 can bind the forearm and wrist, and the adjusting plate 3 slides in the plate slide groove 11. The device can adjust the binding position of the first arm-holding strap 31, the second arm-holding strap 32, and the wrist fixation component 5 to the arm within a certain range according to the length of the patient's arm. The mutual sliding between the locking plate groove 11 and the adjusting locking plate 3 is limited by the limiting component 4. The limiting locking plate 41 engages with the fixed guide rod 42 fixed to the side wall of the adjusting locking plate 3 through the opening of the through hole 411, realizing the installation of the adjusting locking plate 3 on the limiting component 4. When the upper limiting protrusion 412 of the limiting locking plate 41 engages with the circular groove on the side wall of the fixed bracket 1, the adjusting locking plate 3 in the locking plate groove 11... The relative position cannot be adjusted. At this time, the relative length of the fixed bracket 1 and the adjusting plate 3 is fixed. When the relative position of the adjusting plate 3 within the plate slide groove 11 needs to be adjusted, the limiting plate 41 needs to be pulled outward to overcome the elastic force of the spring 43 between the limiting plate 41 and the limiting plate 421. At this time, the limiting protrusion 412 disengages from the outer groove of the fixed bracket 1, and the adjusting plate 3 within the plate slide groove 11 can then be adjusted in relative position. The mutual fixation between the adjusting plate 3 and the wrist fixing assembly 5 is achieved through the mutual fixation between the side wall of the inclined wall base 51 and the adjusting plate 3. The wall thickness of the inclined surface 51 gradually increases along the direction away from the knob-type structure 2, adapting to the significant reduction in dimension at the forearm and wrist. The inclined base 51 is used to install the wrist-binding slider 52 through the opening of the slider rail 511. The wrist-binding slider 52 can be bound to the patient's wrist strap through its outer strap. The feature of the wrist-binding slider 52 moving under the limitation of the slider rail 511 can be adjusted within a certain range according to the relative position of the wrist strap 52 after the second arm strap 32 is bound to the forearm. The limiting pin 53 can lock and limit the relative position of the wrist-binding slider 52 within the slider rail 511.
