Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis, in particular to an arm limiting support frame for hemodialysis nursing. Background Art

[0002] Hemodialysis is a safe and widely used blood purification method that drains blood from the body to the outside, processes the blood through a dialyzer, and then drains the processed blood back into the patient's body. This method is one of the renal replacement therapies for patients with acute and chronic renal failure, and is also one of the safer and widely used blood purification methods.

[0003] However, although the patient's arm will be limited in this operation to ensure that hemodialysis can proceed normally, it does not take into account that when limiting the patient's arm, since each hemodialysis lasts for a long time, the ordinary limiting method requires the patient's arm to maintain one position for a long time, causing soreness and stiffness, which is not only not conducive to the patient's treatment, but also affects the hemodialysis treatment.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 and Figure 2 The utility model provides a technical solution: an arm limit support frame for hemodialysis nursing, comprising a mounting plate 1, a bracket 2 and a placement frame 3, wherein the bracket 2 is fixedly mounted on the surface of the mounting plate 1, the placement frame 3 is rotatably mounted on the top of the bracket 2, a buffer support cloth 4 is detachably mounted on the edge of the upper surface of the placement frame 3 close to the patient's arm, a partition 5 is fixedly mounted on the inner wall of the placement frame 3 close to the patient's hand, a grip ball 6 is arranged on the inner wall of the placement frame 3 above the partition 5, and a fixing piece is arranged on the inner wall of the placement frame 3 between the partition 5 and the buffer support cloth 4 for limiting the patient's wrist;

[0028] It also includes a controller 7, which is fixedly installed on one side of the placement rack 3. A massage roller 8 is provided on the inner wall of the placement rack 3 below the buffer support cloth 4. A movable part for moving the massage roller 8 is provided between the massage roller 8 and the inner wall of the placement rack 3. The movable part is connected to the controller 7 by signal. In this solution, the mounting plate 1 can be installed on the side of the bed and then used. This method only requires the original bed to be installed for use. Then, the patient's arm is placed on the buffer support cloth 4 on the surface of the placement rack 3 to unfold it, and then the patient's arm blood vessels are punctured to complete the preparation for hemodialysis. Then, the patient's wrist is placed on the fixing part to limit the range of movement of the wrist. The two are used in combination to reduce the risk of accidental collision or pulling of the catheter due to the movement of the arm during dialysis, thereby reducing the risk of accidental injury. Since the fixed position is at the patient's wrist, there are generally fewer blood vessels here, and fixing here is not easy to affect the stability of blood flow, and also reduces the impact on hemodialysis.

[0029] Furthermore, connecting ropes 9 are fixedly installed on both sides of the grip ball 6, and the ends of the two connecting ropes 9 away from the grip ball 6 are connected to the inner wall of the placement frame 3. The patient can grasp the grip ball 6, which provides a certain elasticity and feedback to the patient's hands, allowing the patient to feel relaxed when holding it tightly.

[0030] Furthermore, the fixing part includes a wrist fixing frame 10 rotatably mounted on the inner wall of the placement frame 3, the wrist fixing frame 10 is located at the patient's wrist, and a connecting piece for limiting the patient's wrist is provided on the wrist fixing frame 10. The patient can place his wrist on the wrist fixing frame 10, and then limit the range of motion of the wrist through the connecting piece. Here, the wrist fixing frame 10 is rotatably mounted in the placement frame 3, so that the patient's wrist range of motion is limited, but there is still a certain small floating space, so that the patient will not feel too constrained, thereby causing discomfort.

[0031] Furthermore, the connecting piece includes a fixing belt 11 fixedly mounted on one side of the wrist fixing frame 10, a plurality of fixing holes 12 are opened at one end of the fixing belt 11 away from the wrist fixing frame 10, a clamping block 13 is fixedly mounted at the clamping position of the fixing hole 12 on the surface of the wrist fixing frame 10, and the fixing belt 11 and the fixing hole 12 are used in combination, and can be adjusted according to the wrist thickness of different patients and clamped on the clamping block 13, so as to adapt to different patients.

[0032] Furthermore, the fixing belt 11 is made of a flexible material.

[0033] See also Figure 3The utility model provides a technical solution: further, the connecting piece includes a fixing ring 14 movably mounted on one side of the wrist fixing frame 10, and a clamping block 2 15 is fixedly mounted on the side of the fixing ring 14 away from the wrist fixing frame 10. A clamping groove is provided on the surface of the wrist fixing frame 10 corresponding to the movable part of the clamping block 2 15. A buffer pad is provided on the contact surface of the clamping block 2 15 with the patient's skin to give the patient a certain sense of comfort. Since the technology of providing a buffer pad on the contact surface with the skin is very common and belongs to the prior art, it is not described in the claims.

[0034] See also Figure 4 The utility model provides a technical solution: further, the moving part includes a guide rod 16 fixedly installed below the massage roller 8, the guide rod 16 is located on the inner wall of the placement rack 3, and a threaded rod 17 is rotatably installed on one side of the inner wall of the placement rack 3 close to the guide rod 16. A moving block 18 is provided on the guide rod 16 and the threaded rod 17, and a massage roller 8 is rotatably installed on the top of the moving block 18. By controlling the rotation of the threaded rod 17, the massage roller 8 on the surface of the moving block 18 can be driven to roll along the direction of the guide rod 16, so as to massage the arm on the buffer support cloth 4 and help relax the arm muscles. In addition, in this solution, a motor is provided at the end of the threaded rod 17, and the technology for driving the threaded rod 17 to rotate is very common and belongs to the prior art, so it is not described in the claims.

[0035] Furthermore, one end of the moving block 18 is slidably mounted on the guide rod 16 , and one end of the moving block 18 away from the guide rod 16 is threadedly mounted on the threaded rod 17 .

[0036] Furthermore, the surface of the massage roller 8 is provided with a plurality of irregular protrusions, and the provision of the irregular protrusions allows the massage roller 8 to better relax the patient's arm when rolling on the patient's arm.

[0037] Working principle: When the arm limiting support frame for hemodialysis care is used, the patient's arm can be placed on the buffer support cloth 4 on the surface of the placement frame 3 to unfold it, and then the patient's arm blood vessels are punctured to complete the preparation for hemodialysis, and then the patient's wrist is placed on the wrist fixing frame 10, and the range of motion of the wrist is limited by the fixing belt 11. In this process, since the buffer support cloth 4 is made of flexible material and has supporting force, it is convenient to provide support for the patient's arm. At the same time, the use of the wrist fixing frame 10 and the fixing belt 11 can reduce the risk of accidental collision or pulling of the catheter due to arm movement during dialysis, thereby reducing the risk of accidental injury. In addition, since this fixing method is on the patient's wrist, there are generally fewer blood vessels here, and fixing here is not easy to affect the stability of blood flow, thereby reducing the impact on hemodialysis.

[0038] Furthermore, during the dialysis process, considering that the overall dialysis time is relatively long and the patient needs to maintain an action for a long time, a massage roller 8 is added. By controlling the rotation of the threaded rod 17, the massage roller 8 on the surface of the movable block 18 can be driven to roll along the direction of the guide rod 16, so as to massage the arm on the cushioning cloth 4, help relax the arm muscles, and reduce the fatigue caused by long-term dialysis. In this process, the patient can grasp the grip ball 6 to provide a certain elasticity and feedback to the patient's hand, so that the patient can feel relaxed when holding it tightly, which further helps to relieve anxiety and tension.

[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
