Embodiment 2

[0043] Such as image 3 As shown, the heat-preserving and fixing device for dialysis tubing used in nephrology arm internal fistula in this embodiment has the same structure as that in Embodiment 1, the difference is that it also includes a pressure detection mechanism 5, and the pressure detection mechanism 5 includes two oppositely arranged splints 51 , the clamping plate 51 is provided with a pressure sensor, and a clamping gap 52 for clamping the dialysis tube 3 is formed between the two clamping plates 51 , and the clamping plate 51 is detachably connected with the protective assembly.

[0044] The heat-preserving and fixing device for dialysis tubing used in nephrology arm internal fistula of this embodiment monitors the pressure in the dialysis tubing 3 by setting a pressure detection mechanism 5, through which the pressure detection mechanism 5 can monitor the blood flow pressure in real time, so that when the patient is in the dialysis process When dangerous situation...

Embodiment 3

[0048] Such as Figure 4 As shown, the heat preservation and fixing device for dialysis tubing used in internal fistula of the nephrology department of this embodiment has the same structure as that of Embodiment 2, the difference is that a heating mechanism 6 is also provided in the protective assembly, and the heating mechanism 6 is connected to a controller , the controller controls the heating mechanism 6 to heat the dialysis tube 3 in the tube winding mechanism 4 .

[0049] The heat-preserving and fixing device for dialysis tubing used in internal fistula of the nephrology arm in this embodiment heats the dialysis tubing 3 in the coiling mechanism 4 by setting the heating mechanism 6 to increase the temperature of the blood flowing back into the human body and further reduce the discomfort of the patient due to temperature changes. When the situation arises, the pain caused by the dialysis process is reduced, and the danger caused by the temperature change to the physiolo...

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a heat-preservation and fixing device for dialysis tubes for arm internal fistula in the nephrology department, the fixing device comprises a protection assembly which is fit with the shape of an arm and comprises a first protection part and a second protection part, the arm is sleeved with the first protection part, the first protection part is detachably wrapped with the second protection part, tube winding mechanisms which are used for accommodating dialysis tubes are arranged between the first protection part and the second protection part, the area, exposed in the air, of the arm is reduced by the protection assembly, the length of the dialysis tubes suspended between the patient and a dialysis machine is reduced, the possibility of distortion and folding of the dialysis tubes is reduced, the length of the dialysis tubes exposed in the air is reduced, loss of the temperature of the blood in the dialysis tubes is reduced, the patient dialysis pain is reduced, and the dialysis process can be conducted smoothly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a heat preservation and fixing device for dialysis tubes used in nephrology arm internal fistula. Background technique [0002] Hemodialysis is the process of draining blood from the body to the outside, removing metabolic waste and excess water in the blood through a dialyzer, and then returning the purified blood to the body. It is one of the renal replacement therapy methods for patients with acute and chronic renal failure. 1. At present, arteriovenous fistula is usually performed in the arm through surgery for hemodialysis. The artery near the wrist and the adjacent vein are sutured to form an autologous arteriovenous fistula or an artificial blood vessel is placed in the arm to connect adjacent veins. arteriovenous fistula is formed, and during hemodialysis, an arterial needle and a venous needle connected to the dialyzer through a dialysis tube are used to puncture the int...
