Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a PICC arm circumference measuring ruler. Background Technology

[0002] PICC is an abbreviation for "Peripherally Inserted Central Catheter." It's a medical technique that involves inserting a catheter through a peripheral vein (such as the basilic vein) to a central venous vein, usually the superior vena cava. The main function of a PICC catheter is to provide intravenous access for long-term intravenous drug therapy, fluid infusions, blood product transfusions, and nutritional support. Its advantages include reducing the pain of repeated punctures, protecting blood vessels, reducing the incidence of phlebitis, and allowing it to remain in place for months or even a year. PICC catheters are suitable for various situations, including patients requiring long-term intravenous therapy, chemotherapy patients requiring the infusion of stimulating or hypertonic chemotherapy drugs, patients requiring parenteral nutrition support, and patients requiring long-term hospitalization and bed rest. Insertion and maintenance of PICC catheters require professional medical personnel and must be performed in a sterile environment.

[0003] Measuring arm circumference is crucial in the use and care of PICC (peripherally inserted central catheter) for several reasons: 1. To check for swelling at the puncture site: Comparing arm circumference before and after insertion allows observation of any swelling, which could be a sign of vascular damage or other complications during insertion. 2. To assess the effectiveness of PICC placement: Regularly measuring arm circumference and comparing it with previous data helps evaluate the placement's effectiveness. Significant differences in arm circumference may indicate infection or other complications, requiring immediate medical attention. 3. To monitor for thrombosis risk: During hospitalization or home care, measure arm circumference 10cm above the elbow crease daily and compare it to previous measurements. An increase of more than 2cm in upper arm circumference may indicate early thrombosis risk, necessitating an ultrasound examination.

[0004] Existing technology uses a measuring tape to measure the patient's arm circumference. However, due to the operating habits of medical staff and the force with which the measuring tape is wound, errors can occur in the measured arm circumference. These errors can lead to misjudgments by medical staff regarding the patient's catheter placement, which is not conducive to its widespread use. Summary of the Invention

[0005] In clinical practice, to ensure consistency in each measurement, a fixed location needs to be selected as the measurement point, typically 10 cm above the elbow crease on the arm where the PICC line is inserted. A soft measuring tape is generally used. During the measurement process, the operator first needs to measure the position 10 cm above the patient's elbow crease, then, using this position as the starting point, place the tape firmly against the skin and wrap it around the entire arm. This process is cumbersome and cannot guarantee accurate positioning each time. To facilitate clinical nursing procedures and achieve more accurate measurements, the purpose of this invention is to provide a PICC arm circumference measuring tape.

[0006] The PICC arm circumference measuring tape includes a measuring tape, which consists of a housing and a tape measure wound inside the housing. The tape measure is 1 cm wide and has printed graduation lines on the front, as well as auxiliary graduation lines for measuring the upper limb arm circumference. A retractable measuring scale is provided on one side of the measuring tape housing, and the end of the retractable scale is the elbow crease mark. The tape measure's outlet is below the retractable measuring scale to prevent the measuring tape from folding during use.

[0007] Furthermore, the retractable measuring ruler has a length of 5cm and a length of 10cm when extended.

[0008] Furthermore, the measuring tape contains a coiled spring. When the measuring tape is used, the spring is stretched, storing elastic potential energy. When the measuring tape is released, the spring releases the stored energy, causing the measuring tape to automatically retract, making it convenient to use.

[0009] Furthermore, the retractable measuring tape has a magnet at the exit of the tape measure, which magnetically attracts the iron piece at the end of the tape measure, facilitating stretching and fixing during use.

[0010] Furthermore, the elbow crease marking is made of soft silicone, which is placed against the elbow crease during use to facilitate quick measurement of the target arm circumference.

[0011] Instructions for use: When performing PICC insertion or catheter maintenance, it is necessary to measure the patient's upper arm circumference. The circumference is usually measured 10cm above the elbow crease, ensuring that the measurement is taken at the same location each time.

[0012] Have the patient bend their upper arm to locate the elbow crease. Using the elbow crease as the starting point, use the end of a ruler to measure 10cm above the elbow crease. At this location, use a measuring tape to measure the patient's arm circumference.

[0013] In summary, this invention offers the following advantages: by optimizing the structure of a traditional measuring tape, it facilitates storage while incorporating a retractable measuring scale to enable various measurement functions and meet diverse measurement needs. It can achieve upper arm circumference measurement specifically for PICC (Personalized Carrier Components). When used for PICC upper arm circumference measurement, the retractable measuring scale is fixed in position and can be easily retracted after measurement, making storage convenient.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0017] Example 1

[0018] The PICC arm circumference measuring tape includes a measuring tape, which includes a housing 1 and a measuring tape 2 wound inside the housing 1. The measuring tape 2 is 1cm wide and has a front scale line printed on the front, as well as auxiliary scale lines for measuring the arm circumference of the upper limb. A retractable measuring scale 3 is provided on one side of the measuring tape housing 1. The end of the retractable scale is the elbow crease mark 5. The outlet of the measuring tape 2 is below the retractable measuring scale 3 to prevent the measuring tape from folding during use.

[0019] Furthermore, the retractable measuring ruler 3 has a length of 5cm, and a length of 10cm when extended.

[0020] Furthermore, the measuring tape contains a coiled spring. When the measuring tape is used, the spring is stretched, storing elastic potential energy. When the measuring tape is released, the spring releases the stored energy, causing the measuring tape to automatically retract, making it convenient to use.

[0021] Furthermore, the extendable measuring tape 3 has a magnet 4 at the outlet of the measuring tape 2, which magnetically attracts the iron sheet at the end of the measuring tape 2, facilitating stretching and fixing during use.

[0022] Furthermore, the elbow crease mark 5 is made of soft silicone, which is placed against the elbow crease during use to facilitate quick measurement of the target arm circumference.

[0023] Instructions for use: When performing PICC insertion or catheter maintenance, it is necessary to measure the patient's upper arm circumference. The circumference is usually measured 10cm above the elbow crease, ensuring the measurement is taken at the same location each time. Have the patient bend their arm. Starting from the inner elbow crease, measure upwards along the upper arm, marking a point 10cm from the starting point. Then, use a measuring tape to measure the patient's upper arm circumference at the marked location.
