Problems solved by technology

[0004] Hemodialysis is currently one of the main treatment measures for chronic renal failure. In general, outpatients with regular hemodialysis routinely need to undergo 5 hemodialysis treatments every 2 weeks, and each dialysis arteriovenous fistula is punctured with two needles. A total of 264 needles were punctured each time. If the method of directly puncturing the blood vessel is used to communicate with the blood vessel each time, it will not only increase the pain of the patient, but also frequently puncture the blood vessel to easily cause vascular disease, resulting in vascular calcification, arteriovenous Thrombosis and hemangioma formation

Embodiment 1

[0043] like Figure 1 to Figure 4 The X-shaped hemodialysis port shown includes a main body and a puncture cover detachably mounted on the main body. The main body includes a base 1 and four connecting parts 2 distributed in an X shape on the outer periphery of the base 1. The four connecting parts 2 are connected to the outer periphery of the base 1 respectively. The four ports of the severed artery and vein are anastomosed. The puncture cover divides the base 1 into two interconnected arterial chambers and venous chambers. The arterial chamber communicates with two of the connecting parts 2, and the venous chamber communicates with the other two connecting parts 2, thus forming an arteriovenous chamber. Fistula X-type hemodialysis port. By implanting the X-type hemodialysis port of this embodiment subcutaneously to replace the traditional arteriovenous fistula, during hemodialysis, two puncture needles only need to puncture the patient's epidermis and the puncture cover to ...

Embodiment 2

[0051] like Figure 5 and Image 6 As shown, the structure of this embodiment is similar to that of Embodiment 1, except that the two first through holes 3 - 1 are not connected to each other and the control structure 8 is different.

[0052] Specifically, the regulating structure 8 includes a partition 8-4 and a pressing mechanism arranged between the two central diaphragms 3, and the partition 8-4 is provided with a second through hole 8 having the same size as the first through hole 3-1. -4-1. The pressing mechanism includes a U-shaped frame 8-5 fixedly installed between the two central diaphragms 3, the partition 8-4 is movable up and down in the frame 8-5, and the bottom of the partition 8-4 is in contact with the frame 8-5. Springs 8-6 are provided between them. The partition plate 8-4 is provided with a heart-shaped groove 8-4-2, and the bottom of the frame 8-5 is rotated with a connecting rod 8-7, and the upper end of the connecting rod 8-7 is provided with a heart-...

Abstract

The invention discloses an X-shaped hemodialysis port which comprises a main body and a puncture cover detachably installed on the main body, the main body comprises a base and four connecting parts distributed on the periphery of the base in an X shape, the puncture cover is suitable for dividing the base into an arterial chamber and a venous chamber which are communicated with each other, the arterial chamber is communicated with two of the connecting parts, and the venous chamber is communicated with the other two connecting parts. The X-shaped hemodialysis port is implanted subcutaneously to replace traditional internal arteriovenous fistula, during hemodialysis, the two puncture needles only need to puncture the epidermis and the puncture cover of a patient, hemodialysis can be conducted, and pain and side injuries caused by repeated blood vessel puncture of the patient are relieved; and in addition, the body is detachably connected with the puncture cover, the puncture cover is convenient to replace, and the use cost of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an X-type hemodialysis port. Background technique [0002] Hemodialysis (HD), commonly known as kidney dialysis, is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the patient's body to the outside of the body through a dialyzer composed of countless hollow fibers. The principles of ultrafiltration, adsorption and convection exchange substances, remove metabolic wastes in the body, maintain electrolyte and acid-base balance; at the same time remove excess water in the body, and return the purified blood to the patient's body, thereby replacing the kidneys to metabolize toxins and maintain life. [0003] Generally, during dialysis operations, needles are inserted in the arteries and veins of the forearm respectively, and the blood is drawn out from the arteries, and then reinfused through the veins after ...
