A dispense tip for low-volume dispensing is formed according to a process. The process comprises forming a hole through a length of a neck formed of a body of material; forming an inlet hole at a distal end of the hole, the inlet hole having a first inner diameter; forming an outlet hole at a distal end of the inlet hole, the outlet hole having a second inner diameter less than the first inner diameter, a first inner taper transitioning the inlet hole from the first inner diameter to the second inner diameter; forming an outer taper having a width that decreases along a longitudinal axis of the length of the hole in a direction of a distalmost end of the outlet hole; and reducing a width of an opening at the distalmost end of the outlet hole to a third inner diameter that is less than the second inner diameter.

Methods and devices for bending a needle are provided. A device embodiment can include a needle bending apparatus for imparting a bend in a needle when a needle is received therein. The needle bending apparatus may include a housing having an aperture for receiving a shaft of a needle; and at least one abutment member comprising a needle interfacing surface for supporting a portion of the needle and providing a surface upon which the needle may be bent.

Provided is a medical hollow needle with a novel structure that allows the efficient passage of blood or other liquids. A medical hollow needle has an inner lumen penetrating it in a direction of a needle axis. An inner circumferential surface of a needle tube constituting a circumferential wall of the inner lumen has a tapered surface with a diameter becoming smaller toward a needle tip formed by deep drawing. An arithmetic mean roughness Ra of the inner circumferential surface in the direction of the needle axis is set as Ra1.0 m.

A penetration test apparatus may include a penetration unit having a needle-shaped conductor formed in the shape of a sharp needle, a guide unit configured to push out the penetration unit such that the needle-shaped conductor bores a side of a battery cell, and a holder configured to receive the penetration unit. When the guide unit pushes the penetration unit, the needle-shaped conductor of the penetration unit can penetrate the side of the battery cell. A battery cell penetration test method using the penetration test apparatus is also disclosed.

In one aspect, the dual bevel needle can include a hollow tube having a proximal end, a distal end, a first lateral side, and a second lateral side opposite the first lateral side; a first needle point at the distal end of the hollow tube; a second point at the distal end of the hollow tube; a first bevel on each of the first lateral side and the second lateral side, the first bevel comprising a first bevel angle relative to a longitudinal axis of the tube; and a second bevel on each of the first lateral side and the second lateral side, the second bevel having a second bevel angle relative to the longitudinal axis of the tube, wherein the first and second bevels each form a portion of an ellipse, the ellipse having an inner cutting edge and terminating in the first and second needle points at the distal end of the tube, the second bevel angle being shallower than the first bevel angle, the second bevel being located adjacent the proximal end of the first bevel, and the inner cutting edge converging to a narrow heel.

The present disclosure relates to a method for manufacturing an insertion guide needle for a continuous blood glucose monitoring device. The present disclosure provides a method for manufacturing an insertion guide needle for a continuous blood glucose monitoring device, by which: an insertion guide needle can be manufactured through a cutting process and a bending process of a needle raw plate, so that a complicated manufacturing process is unnecessary, and can thus be easily manufactured through a simple process; an enlargement incision part for continuous enlargement and incision, etc. can be conveniently manufactured through such a simple processing process, so that a manufacturing cost thereof can be reduced and also the size accuracy of the insertion guide needle can be improved; and, particularly, in a process of inserting the insertion guide needle into skin, the insertion guide needle can be brought into point contact with the skin to cut the skin, and then can continuously cut the skin in an enlarged manner, so as to minimize pains which may occur in the process of inserting the insertion guide needle into the skin, thereby alleviating the sense of repulsion or tension at the time of using the continuous blood glucose monitoring device.
