Description

Nine, invention description: [Technical field of invention] This case is about the adjustment of the puncture depth of the adjustable puncture needle, which is used to adjust [previous technique], and nowadays (4) many medical examination procedures Only two phase 3 blood samples (about ~L) are needed, so that a small amount of sample t hangs from the skin on the selected site or 2 to obtain 'for example, on the finger' and then take the W drop of blood. For example, the common use of household testing instruments such as blood glucose self-monitoring can be generated by the need for a simple and safe blood sampling by a tester. A conventional puncture needle generally has a rigid body and a sterile puncture 70, such as a needle protruding from one end of the body; the needle is used to pierce the skin so that a blood sample can be obtained from the formed puncture wound . Blood is most often collected from the fingertips because it has the most adequate source; however, blood can also be collected from other parts, such as the earlobe or limbs. In order to reduce the anxiety of the user when puncture the skin and to ensure the reproducibility of the puncture result, various puncture devices equipped with springs have been developed. At the same time, in order to match the skin thickness of different patients or different blood collection sites, many puncture devices also provide a design that can adjust the penetration depth. °° is a schematic view of a prior art puncturing device that can adjust the penetration depth of 1354548. As shown in FIG. 1A, the puncture device 10, which generally has a puncture depth, generally has a grip portion 11, a rotatable outer cover 12, and a puncture member 13, wherein the grip portion 11 is used with the puncture device A main body 10 of the 10 is fixed. The puncture element 13 is located in the grip portion and the main body 1〇1, and the outer cover 12 is wrapped on the outer side of the end of the grip portion n, and has an opening 122. To penetrate the site to be punctured, the puncturing member has a holder 131 and a puncturing tip 132. When the puncture element is moved by a spring (not shown) to a puncture direction ρ, the bracket 131 is blocked by a stop surface 112 of the grip u, and the puncture tip is provided. 132, the protrusion M protrudes out of the grip portion U and the outer cover 12; at this time, the length of the puncture needle tip 132 extending from the outer cover 12 is 〇1, which is the puncture device 10 can be punctured The depth inside the skin. As shown in FIG. 1B, the grip portion u of the puncture device 10 and the outer cover 12 respectively have corresponding thread structures m and ΐ2, so that the outer cover 12 can be moved to the puncture direction p via a rotating motion. So that the distance between the stop face 112 of the grip portion n and the opening π 122 of the outer cover a is increased; since the relative position between the piercing member and the grip portion 11 remains unchanged, the outer The movement of the cover 12 into the puncture direction P will cause the length of the puncture needle tip m to extend beyond the outer cover 12 to be shortened so that the depth at which the puncture device can penetrate into the skin will also become shallow. However, such a design allows the puncture device 1 to be slid at a depth to be punctured, and a gap I (shown as ® 1B) is generated between the grip portion 11 and the outer cover 12, The gap j is easy to accumulate salaries and dirt, and the cover 12 is frequently removed and cleaned, which may easily cause damage or loss of parts. Further, when the outer cover 12 is to be returned to the position shown in Fig. 1A by the position shown in Fig. 1A, the user may also be caught in the gap j by the hand while being gripped. In summary, there is a need in the industry for an accessory that can adjust the puncture device's puncture φ 'wood degree, so that when the user adjusts the depth of the puncture, the outer cover of the puncture device does not move back and forth, not only reduces dirt accumulation in the puncture. The opportunity in the gap of the device provides an alternative to the design of the lancing device. For the sake of this, the applicant invented the "adjustable fittings for the puncture device" in view of the lack of the prior art, and Xiao improved the lack of the above means. _ [Summary of the Invention] The main purpose of the present invention is to provide an adjustable fitting for a puncture device for adjusting the puncture depth of the puncture device, and the adjustable fitting does not form a gap between the components when used, thereby reducing dirt accumulation.
