摘要:
A bodily fluid sampling device (40) is operable to lance with a precise depth and express fluid from both fingertip and alternate sites. In one form, the device is operable to adjust the penetration depth of the lancet into the skin. The bodily fluid sampling device (40) includes a lancet (50) adapted to form an incision in skin (S). A skin contacting member (46) has an orifice (84) through which the lancet (50) extends when lancing the skin. The orifice (84) has a first opening size that is sized to flatten the skin around the lancet (50) during lancing. The orifice (84) has a second opening size that is larger than the first opening size after the incision is formed to express fluid from the incision.

The invention concerns a disposable device for analyzing body fluid especially for blood sugar tests comprising a container which can be inserted into a measuring apparatus, a sampling member provided in the container to pierce skin of a body part and sample body fluid, and a test member for receiving body fluid obtained by the skin-piercing. According to the invention it is proposed that the test member is fixed in a retaining chamber of the container, and the sampling member is configured in the same retaining chamber such that it is separated at a distance from the test member in an initial state and is in contact with the test member to transfer body fluid in a transfer state after the skin-piercing.

An integrated lancing test strip includes a test strip and a lancet packet coupled to the test strip. The lancet packet includes a sterility sheet enclosing a lancet to maintain the sterility of the lancet and prevent cross-contamination between the test strip and the lancet. The sterility sheet allows the lancet to be sterilized separately from the test strip. In one form, a firing mechanism has a blade that punctures and slits the sterility sheet during the firing cycle to reduce the chance of cross contamination between the lancet and the test strip prior to use. This allows an operator to load and subsequently remove an unused integrated lancing test strip without compromising the sterility of the lancet. The lancet includes an engagement opening in which the blade of the firing mechanism engages the lancet. The engagement opening is configured to reduce the chance of the blade becoming dull.

Apparatus and methods for medicament delivery. The apparatus may include, and the methods may involve, a delivery device for delivering a target amount of the medicament from a distal end of the device. The device may include a rod for moving a plunger that discharges the medicament from the distal end. The device may avoid or reduce deformation of the plunger during the discharge. The plunger motion may be stopped by detent that interacts with the rod. The apparatus and the methods may provide an operator indication of progress of stages of operation. The device may feature triggers corresponding to stages of medicament displacement from the device, such as pre-delivery stages, including priming.

A method of controlling lancing speed of a lancet structure of a portable handheld medical diagnostic device (10) includes providing an elongated lancet structure (24; 406; 432; 450; 506; 606) having a skin piercing end (90; 408; 434; 462; 508; 608) and a blood transport portion (92; 464; 510; 610) adjacent the skin piercing end (90; 408; 434; 462; 508; 608). The skin piercing end (90; 408; 434; 462; 508; 608) when displaced makes an incision at a skin site to produce an amount of bodily fluid from the skin site and in which the blood transport portion (92; 464; 510; 610) transports the amount of bodily fluid away from the skin site for use by a measurement system (32) in making a physiological measurement. A spring-driven motor assembly (144) is operatively connected to the lancet structure (24; 406; 432; 450; 506; 606). The spring-driven motor assembly (144) displaces the lancet structure (24; 406; 432; 450; 506; 606) toward the skin site to make the incision for producing the amount of bodily fluid and retracts the lancet structure (24; 406; 432; 450; 506; 606) to carry the amount of bodily fluid away from the skin site. A speed control mechanism (36) is engaged with the spring-driven motor assembly (144) as the spring-driven motor assembly(144) retracts the lancet structure (24; 406; 432; 450; 506; 606) thereby decelerating the lancet structure (24; 406; 432; 450; 506; 606) as the lancet structure (24; 406; 432; 450; 506; 606) is retracted away from the skin site.
摘要:
A method of assembling a lancet housing assembly comprising multiple lancets for use in a portable handheld medical diagnostic device for sampling bodily fluids from a skin site of a patient is disclosed. The method includes forming a plurality of lancet structures in a lancet sheet. The lancet sheet has a removable ledge for releasing the lancet structures. The removable ledge of the lancet sheet is flexed for releasing the lancet structures from the removable ledge.
