Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, specifically to an arm support device for hemodialysis patients. Background Technology

[0002] During hemodialysis, patients have two dialysis tubing connected to their arms via a puncture needle. To prevent blood flow obstruction caused by bending or twisting of the tubing, and to avoid the puncture needle detaching from the body and causing blood purification failure, patients must keep their arms stable throughout the process. Therefore, some devices exist to help stabilize the patient's arm. However, the patient's arm is still exposed during hemodialysis. In cold weather, especially in winter, the patient's arm is prone to feeling cold. Simply covering the patient's arm with a blanket for warmth makes it difficult for medical staff to observe, and the blanket can easily come into contact with the puncture needle and dialysis tubing, potentially causing accidental detachment. Therefore, further improvements are needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an arm support device for hemodialysis patients that has good overall applicability, allows medical staff to directly observe the patient's arm, effectively avoids direct contact of cold air with the patient's arm, can be irradiated for warmth, does not require a quilt for covering, and effectively avoids accidental traction and dislodgement of the puncture needle and dialysis tubing.

Detailed Implementation

[0023] The present invention will be further described below through specific embodiments.

[0024] like Figures 1 to 7 As shown, the present invention provides an arm support device for hemodialysis patients, comprising a base plate 1, a support plate 2, a transparent protective cover 3, a flexible shield 4, and a heat lamp 5. The support plate 2 is located on the upper end of the base plate 1. An arc-shaped support groove 21 is provided on the rear side of the upper end of the support plate 2, which supports the arm undergoing hemodialysis. A strap assembly 6 for securing the hand is provided on the front side of the upper end of the support plate 2. The transparent protective cover 3 has a downward-facing and rearward-opening protective cavity 31. The transparent protective cover 3 is detachable via a magnetic suction assembly 7. The transparent protective cover 3 is installed on the upper end of the base plate 1 and is used to cover the support plate 2. The bottom of the front end face of the transparent protective cover 3 is provided with two slots 32 through which the dialysis tubing can pass. The heat lamp 5 is installed on the top of the folding bracket 8. The bottom end of the folding bracket 8 is detachably installed on the base plate 1 and the heat lamp 5 is positioned above the transparent protective cover 3. The flexible shield 4 is fixedly connected to the rear end of the transparent protective cover 3 and is used to cover the gap between the transparent protective cover 3 and the arm. In addition, the transparent protective cover 3 can be made of transparent acrylic material.

[0025] With the support plate 2 in place, the patient's arm undergoing hemodialysis can be supported within the arc-shaped support groove 21 of the support plate 2, and simultaneously secured with the binding strap assembly 6, thereby helping to maintain the stability of the patient's arm during hemodialysis. The transparent protective cover 3 effectively covers the arm undergoing hemodialysis on the support plate 2, preventing cold air from directly contacting the patient's arm. Furthermore, because the transparent protective cover 3 is entirely transparent, it provides excellent visibility, allowing medical staff to directly observe whether there is any leakage or oozing at the puncture site of the patient's arm. Simultaneously, the flexible shield 4 covers the gap between the transparent protective cover 3 and the patient's arm, further enhancing safety. To prevent cold air from blowing in through the gap between the transparent protective cover 3 and the patient's arm, the use of the heat lamp 5 further warms the patient's arm inside the transparent protective cover 3, ensuring the patient's arm feels warm and does not get cold. This eliminates the need for a blanket for warmth, effectively preventing accidental detachment of the puncture needle and dialysis tubing. Furthermore, in warmer weather or during summer, the transparent protective cover 3 and the flexible shield 4 can be easily removed to prevent the patient's arm from becoming stuffy. It also facilitates the removal of the folding bracket 8 from the base plate 1 to access the heat lamp 5, resulting in better overall applicability.

[0026] The magnetic attraction component 7 includes multiple first magnets 71 and multiple second magnets 72. Multiple first magnets 71 are fixedly provided at the bottom of the transparent protective cover 3, and multiple second magnets 72 are fixedly provided at the top of the base plate 1. The multiple first magnets 71 and multiple second magnets 72 correspond one-to-one and are mutually attracted, thereby facilitating the quick assembly and disassembly of the transparent protective cover 3 and the base plate 1. In addition, strip-shaped locking blocks 33 are fixedly provided on both the left and right sides of the bottom of the transparent protective cover 3, and strip-shaped slots 11 are provided on both the left and right sides of the top of the base plate 1. The strip-shaped locking blocks 33 are adapted to the strip-shaped slots 11 and can be detachably locked into the strip-shaped slots 11, thereby providing a corresponding positioning function for the installation of the transparent protective cover 3 on the base plate 1, facilitating the quick and accurate installation of the transparent protective cover 3, and helping to further ensure the stability of the connection between the two.

[0027] The heat lamp 5 is flat and is a ceramic infrared lamp, which can irradiate and keep the patient's arm warm without producing light stimulation, which is conducive to the patient's rest. The infrared rays can also promote blood circulation. In addition, the ceramic infrared lamp can be a product of the existing technology.

[0028] The folding bracket 8 includes a mounting base 81, a first folding rod 82, and a second folding rod 83. The mounting base 81 is detachably mounted on the base plate 1 via a locking mechanism. The lower end of the first folding rod 82 is rotatably connected to the upper end of the mounting base 81 via a first damping pivot. The upper end of the first folding rod 82 is rotatably connected to the lower end of the second folding rod 83 via a second damping pivot. The upper end of the second folding rod 83 is rotatably connected to one end of the heat lamp 5 via a third damping pivot. Furthermore, the locking mechanism includes at least one locking screw 811. Strip-shaped bent plates 12 are fixedly provided on both the left and right edges of the base plate 1. The mounting base 81 has mounting grooves adapted to the strip-shaped bent plates 12. The mounting base 81 is detachably mounted on the strip-shaped bending plate 12 via the mounting groove. The locking screw 811 is threadedly connected to the upper end of the mounting base 81, and its end can abut against the strip-shaped bending plate 12. Correspondingly, the mounting base 81 is provided with a threaded hole that can be threadedly connected to the locking screw 811. This facilitates the installation of the folding bracket 8 on the left or right side of the base plate 1 to meet actual usage needs. It also facilitates the adjustment of the installation position of the folding bracket 8 along its length on the base plate 1. Furthermore, the foldable positioning of the folding bracket 8 allows it to be folded to a corresponding angle during use, thereby facilitating the adjustment of the installation position, height, and angle of the heat lamp 5 to adjust its illumination position, height, and angle.

[0029] The strap assembly 6 includes a palm strap 61, a connecting ring 62, and a first Velcro strap 63. The connecting ring 62 is fixedly disposed on the front right side of the support plate 2. One end of the palm strap 61 is fixedly disposed on the front left side of the support plate 2. The other end of the palm strap 61 can pass through the connecting ring 62 and be detachably connected to itself through the first Velcro strap 63. In this way, it is convenient to directly bind and restrain the palm, thereby indirectly restraining the arm and avoiding compression of the blood vessels in the patient's arm.

[0030] Two U-shaped clamps 22 are also fixedly provided on the upper front side of the support plate 2 to hold the dialysis tubing, thereby facilitating further positioning of the dialysis tubing.

[0031] Furthermore, the support plate 2 is slidably connected to the base plate 1 via sliding components 9. Two sliding components 9 are arranged spaced apart on the left and right sides. Each sliding component 9 includes a sliding rod 91 and a sliding sleeve 92. The two ends of the sliding rod 91 are respectively fixed to a fixing block 93, which is fixed to the upper end of the base plate 1. Two sliding sleeves 92 are respectively fixed to the front and rear sides of the lower end of the support plate 2. The sliding sleeves 92 are adapted to the sliding rod 91 and are sleeved on it, with a sliding fit between them. Each end of the sliding rod 91 is fitted with a return spring 94 located between the sliding sleeve 92 and the fixing block 93 on the corresponding side. The return spring 94 provides a corresponding elastic buffering effect for the forward and backward movement of the support plate 2. Accordingly, the return spring 94 is a compression spring. Therefore, during prolonged hemodialysis, the patient's arm, along with the support plate 2 as a whole, can make slight forward and backward movements to alleviate discomfort caused by maintaining the same arm position for a long time.

[0032] Furthermore, one side edge of the flexible cover 4 is fixedly connected to the outer periphery of the rear end of the transparent protective cover 3. Both ends of the flexible cover 4 extend outward and are provided with connecting sections 41 that are not connected to the transparent protective cover 3. The connecting sections 41 at both ends of the flexible cover 4 are detachably connected by a second Velcro. After connecting the connecting sections 41 at both ends of the flexible cover 4 by the second Velcro, the other side edge of the flexible cover 4 can be more stably bound to the arm, so that the flexible cover 4 can more stably cover the gap between the arm and the transparent protective cover 3. And because the flexible cover 4 has a corresponding flexible function, it will not cause fixed restraint for slight movements of the arm.

[0033] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
