Description

Technical Field

[0001] This utility model belongs to the field of medical assistive device technology, specifically relating to an upper limb fixation seat for dialysis patients. Background Technology

[0002] In the medical field, dialysis is a common treatment. For many patients with kidney disease and other conditions requiring dialysis, it is a crucial step in maintaining life and improving quality of life. During dialysis, patients need to maintain a stable upper limb position for extended periods to ensure smooth connection and operation of the dialysis tubing, guaranteeing the accuracy and effectiveness of dialysis. Currently, upper limb immobilization devices are commonly used clinically to assist in stabilizing the upper limbs of dialysis patients, helping them maintain stability for longer periods. However, because most immobilization devices have fixed, non-adjustable angles, they cannot be flexibly adjusted according to the actual angle of the patient's arm. Patients have different physical characteristics and habitual postures. Fixing the upper limbs at a fixed angle causes them to be in an unnatural position during long-term dialysis, which can easily lead to muscle fatigue, soreness, and even affect blood circulation, greatly reducing patient comfort and consequently affecting dialysis treatment compliance and effectiveness. Furthermore, when the upper limb is fixed, the fixation device is in direct contact with the patient's upper limb, and during long-term use, it is easy to accumulate dirt such as sweat and skin flakes, which can breed bacteria. Most existing devices are complex in design, and the parts that come into direct contact with the patient are not easy to disassemble, clean, or replace, failing to meet the strict hygiene requirements of medical equipment and increasing the risk of infection for patients. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide an upper limb fixation seat for dialysis patients, which solves the problems of not being able to flexibly adapt to the angle of the patient's arm and the inconvenience of disassembling and cleaning the parts that directly contact the patient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a dialysis patient upper limb fixation seat, comprising a base, a support pad, a clamping seat, an adjusting seat, a fixing strap, and a tray. The top of the base is provided with a first Velcro closure, which is adhesively connected to the bottom layer of the support pad for mounting and fixing the support pad to support the dialysis patient's upper limb. Mounting seats and fixing rings are arranged opposite each other on both sides of the base. The mounting seats are provided with limiting blocks and fixing plates, and have second locking holes. The limiting blocks are adapted to the through holes on the fixing strap. The fixing plate is provided with a second spring clip, which is connected to the second clip hole for fixing the position of the fixing plate and resisting the limiting block to prevent the fixing strap from detaching. One end of the adjusting seat is rotatably connected to the clamping seat, and a second fastening bolt is screwed on at the rotatable connection point for adjusting and fixing the angle of the clamping seat to flexibly adapt to the positioning angle of the patient's upper limb. The other end of the adjusting seat is provided with an adjusting rod, which is inserted into the base and fixed by a first fastening bolt passing through the base for adjusting and fixing the working distance of the clamping seat.

[0005] The beneficial effects of this utility model are as follows: When using this upper limb fixation seat, the support angle can be adjusted by rotating the adjustment seat and the clamping seat to flexibly adapt to the patient's upper limb placement angle. At the same time, the detachable pad and fixation strap make it easy for medical staff to clean and replace them, meet medical and health requirements, and reduce the patient's risk of infection.

[0006] To facilitate the fixation of the patient's upper limb:

[0007] As a further improvement to the above technical solution: a through hole is provided on one side of the fixing strap, and a second Velcro is provided on the other side. The second Velcro is bonded to the outer wall of the fixing strap and is used to fix the position of the fixing strap after it wraps around the limb.

[0008] The beneficial effects of this improvement are as follows: after using the fixation strap to wrap around the dialysis patient's upper limb, simply pass the movable end of the fixation strap through the fixation ring, then fold it back and tighten it, and let the second Velcro be attached to the outer adhesive surface of the fixation strap in a suitable position, so as to fix the position of the fixation strap and thus restrict the patient's upper limb movement.

[0009] To facilitate improved comfort during fixation:

[0010] As a further improvement to the above technical solution: the inner wall of the fixing belt is provided with a protective pad, and the protective pad is soft and elastic to improve the fixing comfort.

[0011] The beneficial effects of this improvement are as follows: by setting up a protective pad on the inner wall of the fixation strap, and the protective pad can be made of soft, elastic materials such as latex, silicone, or memory foam, when the fixation strap is used to wrap around and limit the patient's upper limb, the protective pad comes into contact with the patient's limb, which can effectively reduce the pressure sensation during restraint and fixation and improve the comfort of fixation.

[0012] To facilitate the installation and removal of the fastening straps:

[0013] As a further improvement to the above technical solution: the fixing plate is rotatably connected to the mounting base, and a second spring latch is provided at both ends of the fixing plate, and the second spring latch is engaged with the second latch hole opened at the corresponding position at both ends of the mounting base.

[0014] The beneficial effects of this improvement are as follows: After the fixing strap is installed inside the mounting base, the limiting block passes through the through hole, and then the fixing plate is rotated to the inside of the mounting base, so that the second spring clips on both sides of the fixing plate engage with the second clip holes on both sides of the mounting base. This fixes the fixing plate in position, thereby preventing the fixing strap from detaching from the mounting base. Similarly, when the second spring clips are moved inward and separated from the second clip holes, the fixing plate is unfolded, and the fixing strap can be disassembled for cleaning or replacement.

[0015] To facilitate the installation and use of the upper limb immobilization seat on the hospital bed:

[0016] As a further improvement to the above technical solution: a third fastening bolt is screwed onto the bottom end of the clamping seat, and the top end of the third fastening bolt is located at the inner end of the clamping seat and is provided with a clamping plate.

[0017] The beneficial effects of this improvement are as follows: after the clamping seat is attached to the side of the bed, simply rotating the third fastening bolt upwards will clamp and fix the bed in place with the cooperation of the clamping seat and the clamp plate, so as to realize the installation operation of the upper limb fixation seat on it.

[0018] To enhance the stability of clamping and fixing:

[0019] As a further improvement to the above technical solution: anti-slip pads are provided on the top of the clamping plate and the top wall of the inner end of the clamping seat.

[0020] The beneficial effects of this improvement are: by setting up anti-slip rubber pads, the coefficient of friction can be increased, thereby enhancing the stability of the clamping and fixing.

[0021] To facilitate pallet installation and removal:

[0022] As a further improvement to the above technical solution: the base has an installation groove and a first locking hole on one side, and the installation groove and the first locking hole are connected. The installation groove is connected to the installation plate on one side of the tray, and the first locking hole is connected to the first locking hole corresponding to both ends of the mounting base for mounting and fixing the tray.

[0023] The beneficial effects of this improvement are as follows: when the tray needs to be used, simply insert the mounting plate into the mounting slot and connect the first spring latch with the first latch hole to fix the tray in position so that the patient can place their personal belongings. Conversely, by pressing the first spring latch to separate it from the first latch hole and pulling the tray out, the tray can be disassembled.
