[0002] Arteriovenous fistula is one of the surgical operations, mainly used in hemodialysis treatment. Arteriovenous fistula is a minor operation of vascular anastomosis. The artery and adjacent vein in the forearm near the wrist are sutured so that arterial blood flows in the vein after the anastomosis, forming an arteriovenous fistula. The blood vessels of the arteriovenous fistula can provide sufficient blood for hemodialysis treatment, thus ensuring the adequacy of dialysis treatment.

[0003] Hemodialysis is a renal replacement therapy used to treat conditions such as chronic renal failure. It uses machines to simulate and replace some of the kidney's functions, remove excess waste and water from the body, and maintain the body's water and electrolyte balance.

[0004] At present, in the process of standardized operation of blood purification, the limbs on the arteriovenous fistula side must be managed visually. During the visual management process, it is convenient for nurses to observe the safety of the patient's puncture site and whether the needle is removed. Since the patient's hands and limbs are completely exposed to the outside for a long time, the blood in the patient's limbs cannot be well circulated, and patients with cold limbs can easily feel particularly uncomfortable. In order to improve the warmth and comfort of the patient's limbs during hemodialysis, and to achieve visual management to ensure safety, the present device provides a hemodialysis arteriovenous fistula side limb insulation fixing frame.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides a hemodialysis arteriovenous fistula lateral limb insulation fixing frame, comprising a support frame 1 for placing a patient's limb, a rotating structure 2 for adjusting the angle of the support frame 1, a support bottom for placing a support base 3 and the rotating structure 2, and a heating mechanism 4 for keeping the patient's limb warm, wherein the rotating structure 2 is located on the side end of the support base 3, the side end of the support frame 1 is fixedly connected to the rotating structure 2, the heating mechanism 4 is located inside the support frame 1, and the support base 3 is made of metal;

[0026] When the patient is undergoing treatment, the entire device needs to be supported by the bracket base 3. The bracket base 3 is made of metal, so that when the bracket base 3 is placed on the bed, it can be stably placed on the bed by its own weight, which is convenient for the patient to use. When the patient places the limbs in the support frame 1, there is no need to worry about the instability of the bracket base 3, thereby ensuring the patient's experience and comfort.

[0027] In a further preferred embodiment of the utility model, the bracket base 3 is made of plastic material, a storage groove 31 is provided on one side of the bracket base 3, a movable groove 32 is provided outside the storage groove 31, a sealing plate 33 is provided inside the movable groove 32 and is slidable left and right, and the storage groove 31 is blocked by the sealing plate 33;

[0028] When medical staff need to take the device when treating patients, because the bracket base 3 in the device is made of metal and is relatively heavy, it is not convenient for medical staff to take, use and transport it. Therefore, when the bracket base 3 is made of plastic, it is lighter and more convenient to take and transport. However, when the patient uses it, the bracket base 3 may be unstable because it is made of plastic. At this time, the medical staff only needs to open the sealing plate 33 of the bracket base 3 to expose the storage slot 31 to the outside, and then put the required heavy objects into the storage slot 31 to increase the weight of the bracket base 3, so that it is more stable after being placed on the bed, thereby facilitating the medical staff to take, use and transport it, and ensuring the safety of the patient.

[0029] In a further preferred embodiment of the utility model, the rotating structure 2 includes two fixing blocks 21, a nut 22 and a bolt 23, the two fixing blocks 21 are respectively located on the side ends of the bracket base 3 and are symmetrically arranged, the bolt 23 is located on the two fixing blocks 21 and is rotatably connected, and the nut 22 is located at the end of the bolt 23 and is threadedly connected;

[0030] When medical staff treat patients, since patients will suffer from limb numbness due to being on the support frame 1 for a long time, the angle of the support frame 1 needs to be adjusted to make the patient's limbs in a more comfortable state with adjustable angle. At this time, the patient only needs to loosen the nut 22 at the end of the bolt 23, and then turn the bolt 23 at the adjustment head end. The rotation of the bolt 23 will synchronously drive the support frame 1 to rotate, thereby realizing the angle adjustment of the support frame 1, so that when the patient places his limbs on the support frame 1 for a long time, he can adjust the desired limb placement angle independently and arbitrarily, thereby improving the patient's comfort.

[0031] In a further preferred embodiment of the utility model, the support frame 1 includes a fixing plate 11, a supporting plate 12 and a partition plate 13, the fixing plate 11 is located under the side end of the support frame 1 and is fixedly connected to the screw, the supporting plate 12 is located on the fixing plate 11 and is fixedly connected, the supporting plate 12 is arranged in an arc shape, the partition plates 13 have two and are respectively located on both sides of the supporting plate 12, and the partition plates 13 are provided with air holes 5;

[0032] When medical staff treat patients, due to the long treatment process, the patient's limbs will become numb and need to move. During the movement, the patient's limbs may be separated from the support frame 1, which may cause danger. By setting the partitions 13 on both sides of the support plate 12 on the device, when the patient places the limbs in the support frame 1, the partitions 13 on both sides of the support plate 12 play a barrier role, which can effectively prevent the risk of separation of the patient's limbs and the support frame 1, and ensure the separation of the patient's limbs. Through the setting of the ventilation holes 5 on the device, it is more convenient for medical staff to take it and it also plays a ventilation role for the patient's limbs during treatment in summer, thereby improving comfort.

[0033] In a further preferred embodiment of the utility model, the heating mechanism 4 includes a heating pad 41, a temperature control switch 42 and a plug 43, the heating pad 41 is connected to the temperature control switch 42 by wire, the temperature control switch 42 is connected to the plug 43 by wire, and the plug 43 is connected to a power source;

[0034] When patients are treated in cold weather, their limbs may become stiff and their blood circulation may be poor due to long-term exposure of the limbs. At this time, medical staff only need to place the heating pad 41 in the support frame 1, connect the plug 43 to the power supply, and then use the temperature control switch 42 to adjust the temperature to a suitable state, so that the heating pad 41 can be used to keep the patient's limbs warm and heat them, so that the patient's limbs are kept in a constant temperature state, thereby preventing limb stiffness and poor blood circulation and improving the patient's comfort.

[0035] In a further preferred embodiment of the present invention, an adhesive layer is provided at the lower end of the bracket base 3, and a protective film is provided on the adhesive layer.

[0036] When medical staff is treating a patient, both the bracket base 3 made of plastic and the bracket base 3 made of metal need to use gravity to achieve a certain stability. At this time, an adhesive layer is provided at the lower end of the bracket base 3, and a protective film is provided on the adhesive layer. Medical staff can peel off the protective film under the bracket base 3, and then stick the lower end of the bracket base 3 to the bed body to achieve a fixing effect.

[0037] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
