Abstract
The utility model relates to a corrugated hollow fiber tube which comprises a hollow fiber tube body (1) that is provided with a through hole (11) along the tube body direction, wherein the hollow fiber tube body (1) is of a wave shape which twists left and right along a straight line direction. The flow rate of dialyzed blood in a tube hole can be reduced by utilizing the corrugated hollow fiber tube, the dialyzed blood applies large pressure on the wall of the tube, the contact area between the blood and the tube wall is large, so that the dialysis effect and the dialysis speed can be improved. The corrugated hollow fiber tube can improve the dialysis treatment effect, thus reducing the dialysis times of a patient indirectly and saving the dialysis cost.
Description
Technical field
The utility model relates to medical equipment, is specifically related to a kind of hollow fiber conduit.
Background technology
Hollow fiber conduit in existing haemodialysis control unit dialyzer is hollow straight tube, blood directly flows through its hollow tube hole, very fast by the dialysis velocity of blood flow, the pressure that tube wall is produced is less, also less with the contact area of tube wall, blood in pipe can not be outer with pipe liquid carry out dialysis exchange fully, have influence on effect and the speed of dialysis.
Summary of the invention
The purpose of this utility model is to provide the corrugated hollow fiber conduit that a kind of pressure that can reduce by dialysis blood the flow velocity in pore, by the blood of dialysing, tube wall be produced is large, large with the contact area of blood, can improve dialysis-effect and speed.
Technical solution of the present utility model is: it comprises prolongs the hollow fiber conduit body that the body direction is provided with through hole, and the hollow fiber conduit body is the corrugated of left and right Hui Qu along rectilinear direction.
Technique effect of the present utility model is: use it can reduce by the flow velocity of dialysis blood in pore, pressure tube wall produced by the blood of dialysing is large, large with the contact area of blood, can improve dialysis-effect and speed.It can improve the effect of dialysis treatment, thereby indirectly reduces patient's number of times of dialysing, and saves the dialysis expense.
The accompanying drawing explanation
Fig. 1 is that structural representation cuts open in the utility model embodiment office.
The specific embodiment
As shown in Figure 1, it comprises prolongs the hollow fiber conduit body 1 that the body direction is provided with through hole 11, and hollow fiber conduit body 1 is the corrugated of left and right Hui Qu along rectilinear direction.
The two ends of hollow fiber conduit body 1 are provided with the straight tube head 12 consistent with hollow fiber conduit body 1 main direction.The width of hollow fiber conduit body body 1 left and right Hui Qu is its diameter 1.5 to 3 times.
Claims (3)
1. corrugated hollow fiber conduit, it comprises prolongs the hollow fiber conduit body (1) that the body direction is provided with through hole (11), and it is characterized in that: hollow fiber conduit body (1) is the corrugated of left and right Hui Qu along rectilinear direction.
2. corrugated hollow fiber conduit as claimed in claim 1, is characterized in that the two ends of described hollow fiber conduit body (1) are provided with the straight tube head (12) consistent with hollow fiber conduit body (1) main direction.
3. corrugated hollow fiber conduit as claimed in claim 1, the width that it is characterized in that described hollow fiber conduit body body (1) left and right Hui Qu is its diameter 1.5 to 3 times.
