Description

Technical Field

[0001] The utility model belongs to the technical field of hemodialysis, and relates to a hemodialysis internal fistula arm fixing device, in particular to a hemodialysis internal fistula arm fixing device with charging and heating functions. Background Art

[0002] Hemodialysis is the process of removing certain pathogenic substances from the patient's blood through a dialyzer to purify the blood and achieve the purpose of curing the disease. During hemodialysis, the patient's arm needs to remain in a fixed position to ensure stable blood flow and prevent the puncture needle from shifting.

[0003] However, during hemodialysis, the traditional adhesive tape is currently used for fixation, and it is difficult for patients to keep their arms fixed in one position for a long time without moving. Moreover, after falling asleep, patients will unconsciously move their arms, which may cause the needle to fall off and shift, causing pain to the patients. At the same time, some patients have poor conditions for internal fistula blood vessels, and can only choose to have an vascular fistula on the inner and lower side of the arm for hemodialysis. In this way, the arm is placed flat on the bed after puncture, which is easy to cause blood vessels to be compressed, resulting in insufficient blood flow and affecting the effect of hemodialysis. In addition, some patients have hemiplegia on the side of the internal fistula arm, and cannot adjust the position of the arm autonomously, which will cause the arm to shift involuntarily. Moreover, in winter, the punctured arm is placed in the quilt, and bleeding at the puncture site is difficult to observe in time. It is placed outside the quilt, which causes the patient's arm to be cold and stiff, and the blood vessels to contract, resulting in insufficient blood flow, affecting normal hemodialysis treatment.

[0004] Therefore, in view of the defects existing in the above-mentioned prior art, it is necessary to develop a new type of hemodialysis fistula arm fixation device. Utility Model Content

[0027] Aiming at the problems existing in the prior art of hemodialysis, the utility model provides a hemodialysis fistula arm fixation device with charging and heating functions. Figure 1-3 As shown, the hemodialysis fistula arm fixing device with charging and heating function of the utility model comprises an outer box 1. Both ends of the outer box 1 are open so that the hemodialysis fistula arm can be placed therein.

[0028] In the present invention, preferably, the outer box 1 is made of hard polyvinyl chloride material, so that it has a certain supporting capacity and is easy to clean and wipe for disinfection.

[0029] More preferably, a non-slip material layer 2 is attached to the lower surface of the bottom plate of the outer box 1. Thus, when the outer box 1 is placed on the bed sheet, it is not easy to shift.

[0030] A battery receiving slot 8 is provided in the bottom plate of the outer box 1 and a rechargeable battery is provided in the battery receiving slot 8 .

[0031] Preferably, a battery cover 4 is provided at the end of the outer box 1. The battery cover 4 is used to cover the end opening of the battery receiving slot 8. This facilitates the replacement of the battery when the rechargeable battery ages in the later stage.

[0032] More preferably, a USB interface 6 is further provided on the outer side of the outer box 1. The rechargeable battery can be charged through the USB interface 6. Thus, it is convenient to charge the rechargeable battery.

[0033] Preferably, the side of the outer box 1 is further provided with a battery heat dissipation net 3. That is, the side of the battery receiving slot 8 is hollowed out. Thus, it is convenient to dissipate heat for the rechargeable battery and ensure safety.

[0034] An electric heating mechanism 9 is provided on the inner side of the outer box 1 and a gear button 5 is provided on the outer side of the outer box 1. The electric heating mechanism 9 is connected to the rechargeable battery through the gear button 5. Thus, the electric heating mechanism 9 can be powered by the rechargeable battery, so that the electric heating mechanism 9 generates heat. In this way, the problem that the puncture arm is placed outside the quilt in winter, which easily causes the patient's arm to be cold and stiff, and the blood vessels to contract, resulting in insufficient blood flow, affecting normal hemodialysis treatment is solved.

[0035] The gear button 5 can be set to 2 gears. Thus, the heating temperature of the electric heating mechanism 9 can be adjusted according to the different thermal sensitivity of each person, so as to avoid discomfort to the patient caused by too high or too low temperature.

[0036] The gear button 5 can be a current regulating button. By pressing the gear button 5, the current supplied to the electric heating mechanism 9 can be adjusted, thereby adjusting the heating temperature. The current regulating button is a prior art and can be purchased on the market.

[0037] like Figure 3 As shown, the electric heating mechanism 9 includes an electric heating mesh 92 and a foam 91 wrapping the electric heating mesh 92. The electric heating mesh 92 is connected to the rechargeable battery through the gear button 5, so as to generate heat under the power supply of the rechargeable battery.

[0038] Preferably, the outer side of the foam 91 which is not connected to the outer box 1 is provided with a soft polyvinyl chloride plastic layer 93. Thus, it is convenient to clean and wipe it for disinfection.

[0039] Two movable rest pads 10 are arranged inside the outer box 1. The two movable rest pads 10 are placed at the wrist and elbow of the hemodialysis fistula arm, respectively. Since the rest pads 10 are movable, they are suitable for people with different arm lengths. Moreover, since the two movable rest pads 10 are placed at the wrist and elbow of the hemodialysis fistula arm, respectively, the middle arm is free and does not directly contact the electric heating mechanism 9, so there is no need to worry about the skin being burned, which is very safe and can avoid the discomfort of joints being compressed for a long time.

[0040] Preferably, the rest pad 10 is a sponge pad, for example, a high-density sponge pad. It is not easy to deform under long-term pressure, and can also increase the comfort of the patient. In addition, there is a hollow part in the middle of the rest pad 10, which solves the problem that the blood vessels of patients with fistulas on the inner lower side of the arm are compressed after puncture, resulting in insufficient blood flow and affecting the effect of hemodialysis.

[0041] The outer side of the outer box 1 is also provided with a fixing mechanism 7. The fixing mechanism 7 is used to fix the hemodialysis internal fistula arm in the outer box 1.

[0042] Preferably, the fixing mechanism 7 comprises a plurality of binding straps symmetrically arranged on both sides of the outer box 1, and each of the binding straps is provided with Velcro. Thus, the fixing mechanism 7 is designed as an adjustable structure, which can be adjusted according to the patient's arm circumference and the puncture site, so that the fixing mechanism 7 can be firmly fixed on the patient's arm.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Those skilled in the art can modify or replace the technical solution of the utility model according to the idea of ​​the utility model without departing from the essence and scope of the technical solution of the utility model.
