Multifunctional tunnel skin expansion measuring scale

Abstract

The invention discloses a multifunctional tunnel skin expansion measuring scale, which comprises a flat ruler body used for expanding a bag containing an infusion port seat and detecting the size of the corresponding capsular bag and a tunnel needle used for pulling a PICC built-in catheter. The flat ruler body and the tunnel needle are connected into a whole; the length of the flat ruler body isslightly larger than 3.0 cm, the width of the flat ruler body is 1.0 cm, the thickness of the flat ruler body is 1.0 mm, the upper end of the flat ruler body is of a flat arc structure, and the outerend face of the flat ruler body is provided with measuring scale marks A with 2.0 mm as the unit length in the length direction. The outer wall of the tunnel needle is provided with measuring scale marks B with 1.0 cm as the unit length in the length direction of the tunnel needle. The beneficial effects are that the flat ruler body can be used for expanding a capsular bag containing an infusion port seat and detecting the size of the corresponding capsular bag; the tunnel needle can be used for pulling the PICC built-in catheter; the depth of the catheter inserted into the subcutaneous part of the arm of the patient can be controlled in real time by comparing the scales on the catheter, so that the insertion depth controllability is good, even if the catheter is inserted obliquely to enable the front end of the catheter to deviate from a PICC built-in catheter placement point, the catheter can be found and corrected in time; and therefore, the practicability of the measuring scale ishigh.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multifunctional tunnel skin expanding measuring ruler. Background technique [0002] In existing major hospitals, for patients with PICC catheterization, when performing PICC catheterization, it is first necessary to open an insertion point in the patient’s arm, insert the PICC catheter into the patient’s vein, and indwell the outer end of the corresponding PICC catheter At the corresponding insertion point, expand the skin of the patient's arm at a position about 10.0 cm adjacent to the corresponding insertion point to construct a pouch containing an infusion port, and after visually inspecting that the inner diameter of the corresponding pouch is suitable, insert it with a tunnel needle The constructed pouch is subcutaneously inserted along the patient's arm to a certain depth in the outer end of the PICC catheter at the corresponding insertion point, and then the t...

Problems solved by technology

[0004] Specifically, on the one hand, when using a knife to expand the skin of the patient's arm to construct the pouch for the infusion port, there is a problem of inaccurate visual inspection after expansion, and the small inner diameter of the initially constructed pouch makes the infusion port It cannot be completely placed in it, so it is necessary to repeatedly try to install the infusion port seat, and repeatedly use the knife to expand the corresponding pouch until the inner diameter is suitable. It is unstable, which makes it easy to loosen and shift, making the follow-up use effect not good. In this way, for the construction of the pouch, the operation is cumbersome, time-consuming and laborious. In the constructed pouch, there is no scale on the outer wall of the conventionally used tunnel needle, which makes it difficult to control the depth of its insertion into the patient's arm subcutaneously in real time. When deviating from the corresponding insertion point or crossing the corresponding insertion point, the tunnel needle needs to be reinserted. In this way, the operation will be time-consuming and laborious
