Example Embodiment

[0020] The invention discloses a method for measuring the length of a PICC intubation tube, comprising the following steps:

[0021] (1) The patient's upper limb is abducted 90 degrees, and the length of the upper limb marked to the right sternoclavicular joint is measured as A;

[0022] (2) After the puncture is successful, measure the length of the upper limb marked to the puncture point as C;

[0023] The length of PICC cannulation is obtained=A+B-C, where B is the deviation distance, and the upper limb is marked as the obvious characteristic position of the upper limb.

[0024] Here, if the PICC puncture point is above the upper limb mark, the value of C is positive; correspondingly, if the PICC puncture point is below the upper limb mark, the value of C is negative. The upper side is the side closer to the side, and the lower side is the side closer to the finger.

[0025] Among them, the deviation distance B has been studied with various data such as the patient's heig...

Abstract

The invention relates to a PICC catheter length measuring method, and belongs to the clinical technical field of PICC. The method comprises the following steps that (1) a patient lies low lays the upper limbs out in parallel to form 90-degree angle with the side body, and the length A from the upper limb marking to the right sternoclavicular joint is measured; (2) after puncture, the length C between the upper limb marking and the PICC puncture point is measured to obtain the PICC catheter length = A+B-C, wherein B is the deviation distance. The method is simple and easy to operate. After puncture, the position of the PICC puncture point is determined, then the length between the upper limb marking to the length of the puncture point is measured, and the positioning is accurate. The upperlimb marking is the obvious feature position of the upper limb of the patient body, the positioning is accurate regardless of single or multiple measurement, no marking setting is required, and marking blur does not occur. Measured values are more accurate, and the measured values are more precise by means of calculation of the deviation distance B, so that the catheter tip position is more accurate.

Description

technical field [0001] The invention relates to a method for measuring the length of a PICC catheter, belonging to the field of PICC clinical technology. Background technique [0002] The existing methods for measuring the length of the PICC catheter are as follows: [0003] 1. Under the guidance of B-ultrasound, select the puncture point and mark it. [0004] 2. Abduct the upper limbs 90 degrees, measure the length from the marked point to the right sternoclavicular joint, and from the right sternoclavicular joint to the third intercostal space. [0005] 3. Disinfect the skin with the label as the center. [0006] This method seems simple, but the error is large. After the skin is disinfected, the markings will be unclear, and even if they are clearly visible, there will be inconsistencies when repositioning. Contents of the invention [0007] In order to solve the above technical problems, the present invention provides a method for measuring the length of a PICC cat...
