A module for adjusting the launch of a includes: a cam plate slidingly moving longitudinally having a first and second catching parts; a cap lever rotatably coupled to a rotating shaft formed in parallel with the cam plate movement direction, and having a first protrusion moving while being inserted in the first catching part and a cap arm for catching a protective cap; and a collet lever rotatably coupled to the rotating shaft having a second protrusion moving while being inserted in the second catching part and a body arm for catching a lancet body. When the cam plate moves backward to a first point, the collet lever moves backward with respect to the cap lever separating the protective cap from the lancet body. When the cam plate moves backward to a second point, the cap lever and the collet lever rotate so that the lancet body moves forward.

Medical needle assemblies incorporating a needle cover are provided. According to one aspect, the needle cover is integrally formed from a material that: (1) is sufficiently rigid to prevent bending of an underlying cannula, (2) is suitable for allowing a frangible portion thereof to be broken under pre-selected conditions, and/or (3) has a moisture vapor transmission rate sufficient for steam sterilization of a needle tip enclosed by the needle cover. According to another aspect, at least part of a cap portion and a hub portion of the needle cover are translucent. According to yet another aspect, the needle cover is provided with a wing having an enlarged rib suitable for gripping during separation of a cap portion from the remainder of the needle cover.

A blood sensor includes a base (12), a detection part (16) disposed on the base (12), a blood collection needle (13) disposed at a front end (12a) of the base (12), a negative pressure generation part (17) for applying negative pressure to a portion of the blood collection needle (13), and a supply path (15) for supplying blood collected by the blood collection needle (13) to a detection part (16).

A blood sampling device includes a lancet having a skin piercing member disposed at an end thereof. The lancet is slidable within and releasably engaged with an elongated lancet guide that remains stationary with use of the device. A shell is axially movable relative to the lancet guide between a rest position and an actuate position, with the lancet being spring loaded within the lancet guide by movement of the shell from the rest position to the actuate position.

摘要:
A plunger having an oblong body with a front end and a rear end and a lancet having a cutting edge projecting axially from said body at the front end is insertable in a cylinder having an oblong hollow body with a front end, a rear end and an axial hole. The plunger of such a length and the lancet is so arranged that it protrudes a predetermined distance out of the cylinder at the front end when the plunger is inserted thereby defining an operative cutting position. The plunger and cylinder have first engaging stop means arranged after partial insertion of the plunger, to temporarily prevent continued insertion at a predetermined initial position. The arresting function of the stop means is overcome by applying pressure on the plunger thereby pushing it the remaining distance into the cylinder from the initial position to the operative position. The lancet has a single cutting edge extending transversely to the axis of the lancet and a pair of identical inclined surfaces uniformly disposed about the cutting edge.

A plunger having an oblong body with a front end and a rear end and a lancet having a pointed end section projecting axially from said body at the front end is insertable in a cylinder having an oblong hollow body with a front end, a rear end and an axial hole. The plunger of such a length and the lancet is so arranged that the pointed end section of the lancet protrudes a predetermined distance out of the cylinder at the front end when the plunger is inserted thereby defining an operative puncturing position of the medical lancet. The plunger and cylinder have a first engaging stop arranged after partial insertion of the plunger, to temporarily prevent continued insertion at a predetermined initial position. The arresting function of the stop is overcome by applying pressure on the plunger thereby pushing it the remaining distance into the cylinder from the initial position to the operative position.

A lancet device includes a hollow housing defining a cavity and having a proximal end and a distal end and a slider slidable at least partially within the cavity along a longitudinal axis from an outward position to a pushed position. The slider extends outside of the cavity beyond the proximal end when it is in the outward position. A needle holder holding a needle is rotatable about and translatable along the longitudinal axis when moved from an initial position to an extended position. When the needle holder is in the initial position, the slider is in the outward position. When the needle holder is in the extended position, the lance extends beyond the proximal end. Sliding of the slider to the pushed position enables a first biasing member to urge the needle holder toward the extended position. A second biasing member can be present in the lancet device.
摘要:
Needle covers are provided for medical needle assemblies having a base and a cannula. The needle cover includes hub and cap portions. The hub portion is adapted to be secured to the base. The cap portion is adapted to substantially enclose at least a distal end of the cannula when the hub portion is secured to the base. The cap portion includes at least one generally outwardly extending wing having an outer edge and an enlarged rib extending along only a portion of the outer edge of the wing and only in a direction substantially parallel to a central axis defined by the cap portion. The cap portion is separable from the hub portion upon application of a torsional force, with the rib of the wing being thicker than the portion of the wing radially inward of the outer edge to assist gripping during application of such force.
