Problems solved by technology

However, if the iontophoresis method is not properly controlled, it is easy to have negative effects on the blood, for example, it will reduce the levels of potassium ions and sodium ions in the blood, that is, it may cause dielectric diseases. Therefore, it is necessary to control the loading between the two The potential difference across the electrodes and controls the magnitude of the current
[0006] However, it is very difficult to set up a pair of electrodes in the hemodialysis tube, and the construction of the electric field is relatively difficult, and the electric field strength of the constructed electric field in the hemodialysis tube is inconsistent. In order to obtain a higher dialysis rate, it is necessary to load a relative Larger current, the consequence is that the electrolyte balance of the blood is disrupted

Embodiment Construction

[0031] Refer to the manual attached figure 2 , is corresponding to figure 1 Schematic diagram of the axial mid-section structure of , while figure 1 It is a schematic diagram of the main view structure of a hemodialysis element. As a whole, its main structure is a plate structure. This kind of structure can refer to a fixed tube plate heat exchanger. The so-called plate is a plate with a certain thickness as a whole. figure 2 This structure can be clearly reflected.

[0032] Generally speaking, for a board structure, conceptually it has two board surfaces, ignoring its own thickness, although the part surrounding the board surface has a side structure, but is usually called an edge.

[0033] As for the panel structure, although there is only one more word "style", since its thickness cannot be ignored, the two panels corresponding to the panel surface can be called main panels, and the remaining four sides can be called side panels.

[0034] For the plate structure, the ...

Abstract

The invention discloses a hematodialysis element. The hematodialysis element comprises a dialysis room, a dialysate inlet, a dialysate outlet, a blood lumen and a blood lumen tube, wherein the dialysis room is of a square plate type structure and is provided with a dialysis cavity defined by two plate surfaces and four side surfaces; the dialysate inlet and the dialysate outlet are correspondingly formed in the two opposite side surfaces of the dialysis room and form a dialysate lumen together with the dialysis cavity; the blood lumen is distributed on the dialysis cavity along the direction of one side of a square plate type structure, and a semipermeable membrane for dialysis is arranged on the wall of the blood lumen; the blood lumen tube is provided with a blood inlet and a blood outlet which are formed in the two opposite side surfaces of the dialysis room and are used for communicating the corresponding tube and the blood lumen. According to the hematodialysis element, the dialysis efficiency is high, and the negative effect of the hematodialysis element on blood is small.

Description

technical field [0001] The present invention relates to a hemodialysis element. Background technique [0002] Clinically, the so-called hemodialysis (Hemodialysis) refers to the removal of some wastes in the blood (mainly urea, creatine and some toxic compounds produced by the human body) through a semi-permeable membrane. Among them, dialysis refers to the movement of solutes from a high-concentration solution to a low-concentration direction through a semi-permeable membrane. Therefore, dialysis requires a special hemodialysate (referred to as dialysate). The basic principle of hemodialysis and the dialysate and semi-permeable membrane used are known in the art and will not be repeated here. [0003] Due to the long treatment time of hemodialysis, it usually takes three or four hours, which brings great pain to the patient. Therefore, in the hemodialysis machine, the dialysis speed of the original hemodialysis device is improved to reduce the treatment time. [0004] Con...
