Problems solved by technology

However, the patient cannot identify whether a covered needle has been used until the cap is removed and the needle is viewed
Visual inspection of needles can be inconclusive and may lead patients to reuse unsterilized needles in some cases

[0052] According to a first embodiment, the invention relates to an improved lancet 10 for obtaining a blood sample. For example figure 2 As shown in , the lancet 10 of the present invention includes a body 20 including a handle portion 24 and a needle carrying portion 30 for holding one or more needles 40 . The handle portion 24 may be configured to enable the patient to hold and manipulate the lancet, preferably also configured to be retained by the piercing device 60 .

[0053] needle carrying part

[0054] As shown in FIG. 1 , prior art lancets 10 generally have a single needle 40 protruding from the distal surface 38 of the needle-carrying portion 30 . Figure 4A It is further shown that when the lancet of the present invention is used in an existing puncturing device 60, the distal surface 38 of the needle carrying portion 30 contacts the inner surface 66 of the lumen 65 of the puncturing device 60, thereby preventing the lancet body 20 from Advances outwardly and pre...

example 1

[0107] Patients requiring monitoring of blood glucose levels have used the lancets described herein to obtain blood samples. The lancet has a 1 mm long and 0.15 mm diameter needle mounted on a 2 mm long and 1.75 mm diameter holder. The patient also used a regular lancet with a 3 mm long, 0.3 mm thick needle. Lancing procedures with both lancets were performed using the "One-Touch" lancing device manufactured by Lifescan or the "Freestyle" lancing device manufactured by Abbott Laboratories. Blood is obtained from the skin of the patient's fingertip.

[0108] All patients reported less pain when using the lancet of the present invention than when using a conventional lancet. All patients punctured by the lancet of the present invention produced blood volumes sufficient for glucose testing.

example 2

[0110] Thirty diabetic patients participated in an open, randomized clinical study to test the lancet of the present invention. The needle of the lancet is 0.75mm long and 0.15mm in diameter. The standoff is 2.25mm long and the diameter of the top surface of the standoff is 1.75mm.

[0111] Patients were asked to rate the pain they experienced while using the lancet using a pain scale of 0-3, as described in Table 2 below.

Abstract

A lancing system comprising a lancet with a handle portion and a needle bearing portion, the needle bearing portion retaining a thin needle protected by a safety cap. The safety cap includes first and second chambers, where the first chamber acts as a sheath and the second chamber having a surface positioned to compromise the structure of the needle when the needle bearing portion of the lancet body is inserted into the second chamber.
