Lancet

The invention relates to a lancet for performing an incision. The lancet has a blade for providing an incision and a trigger housed in a housing. The trigger has a first trigger arm, a second trigger arm and a flexible member connected to the second trigger arm. A resilient member may be disposed within the housing in a pre-cutting state in which it stores energy and arranged to exert a force for moving the second trigger arm and the blade from a first stowed position through a cutting position and to a second stowed position.

Method and apparatus for penetrating tissue

A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

An auto-retractable blood collection needle, including: a needle holder including a first tube, a second tube and a holder tail; a needle in stalled in the first tube; a built-in sliding sleeve which is elongated and through and has a C-shaped cross section; a needle shield which is hollow and elongated; and a spring sheathed on the first tube. The second tube is installed in the built-in sliding sleeve and is capable of sliding back and forth. The built-in sliding sleeve is installed in the needle shield and is capable of sliding back and forth. A locking mechanism is formed by the holder tail and the needle shield. When the holder tail is unlocked from the needle shield, a force of the spring pushes the second tube to slide backward, and then the built-in sliding sleeve is driven to slide rearward to lock with the needle shield.

Needle holder

A medical needle holder (10) having a generally hollow body (18) which extends in the direction of an axis (62) from a first end (20) to a second end (22). The first end is shaped for reception of a needle (50) therein and the second end is open to allow for insertion of a fluid receptacle (16). The first axis is substantially aligned in use with a needle positioned in the first end of the body. The needle holder comprises a grip portion (28) which extends outwardly from the body in a direction which is angularly offset from the first axis. The grip portion may be actuable between an in-use condition and a disposal condition in which the grip portion covers a needle in the needle holder. The body (18) may comprise control formations on its inner surface to allow for control over the insertion of a fluid receptacle (16) into the body.

POINT-OF-CARE DIAGNOSTIC DEVICE AND A METHOD FOR SECURE USER IDENTITY CONFIRMATION WHILE MAINTAING ANONIMITY
20220142534 · 2022-05-12 · ·

A device and method for performing a diagnostic test, including determining presence or absence of antibodies to a virus. The device displays the results on a display, and includes a retractable needle and an enclosure that houses the retractable needle, a vessel for collecting or storing a bodily liquid sample collected from the subject, an enclosure containing a diluent fluid that is mixed with the collected sample, and at least one area for mixing and performing analysis.

A pressure sensor checks for pressure being applied by the test subject's finger during the test, and stops the test or disables display if it does not sense pressure of the test subject's finger during testing. A processor performs identification testing by scanning a digital fingerprint of the test subject by a digital scanner prior to evaluation, stores the data and evaluates the test results to determine whether the results exceed or reach a threshold value. The testing and evaluation are performed only after a successful identification of the test subject. The device keeps the test information and identification information about the test subject anonymous, and does not communicate the identity of the test subject and the test results to an external device.

A BLOOD SAMPLING DEVICE
20220000402 · 2022-01-06 ·

Blood sampling device comprising a lancet body supporting a lancet tip, said lancet being moveably mounted within a housing, an urging member configured to urge said lancet forwardly in said housing in use from a primed position in which said lancet tip is located within a passage to a lancing position in which said lancet tip projects through an aperture in the forward end of the housing and a removable safety cap. The housing and said safety cap comprise cooperating abutment surfaces and cooperating stop surfaces, with the safety cap being rotatable in a first direction from a first blocked position in which said cooperating abutment surfaces are in abutment alignment to prevent removal of said safety cap from said housing to a second position in which said cooperating abutment surfaces are not in abutment alignment such that said safety cap can be removed from said housing; and wherein said stop surfaces cooperate to limit further rotation of said safety cap in said first direction when said safety cap is in said second position.

The two symmetrical flexible wings include two driving segments configured to abut against the two symmetrical flexible wings to flexibly retract inward by using the two tilted contact faces.

BLOOD COLLECTION SAFETY DEVICES AND METHODS OF USE AND MANUFACTURE

An automatically locking safety device, e.g., for use in a blood collection procedure, can include a housing, first and second needle covers that are at least partly received in the housing, and a needle that is at least partly received in at least one of the first and second needle covers. The needle can include a proximal tip configured for placement into a patient and a distal tip configured for placement into a blood collection vial. In some embodiments, the first and second needle covers are biased by a biasing member. In some cases, one or both of the first and second needle covers can be locked to prevent axial movement thereof after the blood collection procedure. In certain embodiments, a distal end of the device is configured to connect with a medical connector, such as a needleless IV access device.
