An infusion flow regulator includes: a main body having an inlet through which fluid is introduced and an outlet through which the fluid is discharged; and a rotary dial rotatably coupled to the main body, with a sealing member interposed therebetween, so as to regulate a flow rate of the fluid, in which the rotary dial includes a regulating flow path having a shape of a recessed groove in cross section with a first width and a first height, and the regulating flow path includes a first region in which the first width is constant and the first height is decreased, and a second region in which both the first width and the first height are decreased. By the aforementioned configuration, the infusion flow regulator for the fluid can accurately regulate the flow rate even in a region where the flow rate of the fluid is very small.

The present invention discloses a steerable guidewire and a method for manufacturing the same, and a steerable catheter and a method for manufacturing the same. According to an aspect of the present invention, a steerable guidewire, which is inserted into a catheter and guides the catheter to a desired blood vessel, may include: a steerable tip part that can be bent in at least two stages due to a stimulus from the outside and that is steered in a predetermined direction; and a non-steerable tip part that is not steerable. The steerable tip part may include: a first steerable tip part having a first length and bent in a first angle with respect to the non-steerable tip part; and a second steerable tip part having one end connected to the first steerable tip part, having a second length, and bent and steered into a second angle with respect to the non-steerable tip part. The first steerable tip part may be positioned farther from the non-steerable tip part than the second steerable tip part. The first length of the first steerable tip part may be smaller than a sum of lengths of steerable tip parts other than the first steerable tip part, and the first angle may be steered so as to be larger than the second angle.

The present invention relates to an infusion flow-rate regulating device capable of allowing easy attachment and detachment of a flow-rate regulator provided in an infusion solution set and of automatically adjusting a dial of the attached flow regulator such that a fluid is able to be administered at a target flow rate. To this end, the infusion flow-rate regulating device includes a main body, a dial mounting unit rotatably connected to the main body, a flow-rate regulator separation unit for preventing arbitrary separation of a flow-rate regulator mounted on the dial mounting unit, and a controller for controlling a flow rate of fluid.

The present invention relates to an infusion flow adjuster which is used in order to adjust the flow rate of an infusion solution to be administered when performing infusion therapy, and relates to an infusion flow adjuster in which an arc-shaped flow path for adjusting the distance through which the infusion solution passes and a circular flow path for inducing discharge of the infusion solution that has passed through the arc-shaped flow path are constituted in a single plane, and which is easy to produce as a product for accurately adjusting the flow rate, affords convenience of handling being provided with a handle in a suitable position, and also, in addition to allowing fine adjustment of the flow rate, limits the maximum flow rate to an appropriate value, so being convenient to use during actual infusion therapy.

The present invention relates to a direction-controllable drug injection catheter. According to the present invention, provided is the catheter extending along a central axis 'A' including a drug injection part in which a drug injection channel has been formed; a channel opening and closing means which opens and closes the drug injection channel; and a steering structure which is rotationally asymmetric with respect to the central axis 'A' and varies according to a pressure change of the drug injection channel for the purpose of steering.

A portable medical liquid infusion device receives an input of a medical liquid infusion rate (cc/hour), the quantity of medical liquid to be infused or the length of time for infusion, and outputs a recognition signal corresponding to the input, thereby allowing a drip interval to be easily adjusted, and which quantitatively calculates and outputs a medical liquid infusion rate on the basis of a count input which is received in accordance with a drip interval when measuring the medical liquid infusion rate. The medical liquid infusion device judges a count input having an irregular interval as an erroneous input, and renders another count input to be conducted again through automatic resetting, whereby the medical liquid infusion device can output a correct measurement result only, and also can output the length of time for infusing the remaining medical liquid when measuring the medical liquid infusion rate.
