Abstract

An improved depth adjustable cap of lancing device, including a lancet cover 3 with hole A 12 and an adjustable cover with hole B 13. The cover is set on the top of lancet cover 3. The two parts are joint up by screw structure and rotary position structure. Its character is: the adjustable cover is separated into a front cover 11 with hole B 13, a back ring 10 and two pieces of semi-circles. The semicircles from a set shape. The front cover 11 locates in one end of the shape and the back ring 10 located in the other end. There is a screw structure between one semi-circle and lancet cover 3. When rotating the adjustable cover, the rotary position structure makes the adjustable cover move intermittently. And “clicks” can be heard. The screw structure makes the hole B move along the axes to control the exposed lancet length. This program separates the original inner set into four simple parts. Then assemble them into a whole part and weld them with ultrasonic. Its characters: low down the manufacturing difficulty. Make it convenient to assemble. Product'"'"'s quality is improved. Fact shows its effect is very obvious.

Claims

1. An adjustable end cap for a lancing device formed of two semicircles 1, 2 and a cover 3 banded together by an adjustable depth gage back ring 10 inserted in a coaxial cover 3 having means for adjusting the depth of the movement of the lancet for multiple usage comprising:

means separating the adjustable cover from the main cover;

said back ring proportioned to coaxially engage the semicircles 1, 2;

the front cover being secured by the shape of the back ring;

a hole 13 in the end cover 11 for the semi-circle 1, 2;

said means for adjustment including a coacting internal back ring 10 engaging a cam groove 6 in communication with a spline formed of a key 16 and opposed the groove 17.

2. In the device according to claim 1,

the front cover 11 securing the top and bottom 1, 2 by grippingly receiving one end of the top and bottom 1, 2.

3. In the device according to claim 1,

a plurality of depth indicia on the back ring 10.

4. In the device according to claim 3,

a groove and rib constraining the disposable lancet to move longitudinally in its holder.

5. In the device according to claim 4,

one spline member located in the semi-circle and the other in the back ring.
