Description

Technical Field

[0001] The utility model relates to the design and application field of an external measuring ruler, and more specifically to an external measuring ruler for PICC catheterization. Background Technique

[0002] Before PICC catheterization, nursing staff need to first determine the length of catheterization and measure the distance between the patient's upper arm and the superior vena cava, so as to cut the catheter to an appropriate length before or after catheterization to facilitate the fixation of the exposed end after catheterization. At the same time, the nursing staff also need to measure the patient's arm circumference length, so that in case of arm swelling caused by thrombosis or thrombophlebitis, comparison before and after catheterization and comparison between bilateral arms can be carried out. However, ordinary measuring rulers cannot accurately perform the above two length measurement operations simultaneously.

[0003] Chinese Patent: A pre-measuring ruler and measuring device for PICC catheterization, the authorization announcement number is: CN217659866U. This patent discloses the specific structure and usage method of the existing measuring ruler before PICC catheterization. From the content disclosed in the above patent document, it can be known that this measuring ruler can conveniently measure the length of the patient's catheterization upper arm and obtain relatively accurate measurement values, and the operation is relatively simple. However, this measuring ruler cannot complete the measurement of the arm circumference at the same time, and there are certain deficiencies in its use.

[0004] This technical solution is based on the structure of the existing PICC catheterization measuring ruler, and further improves and perfects the structure of the measuring ruler. It can not only simultaneously measure the catheterization length and the patient's arm circumference, but also has accurate measurement values and relatively simple and convenient operation, which is very beneficial to the operation and use of medical staff.

The front end of the longitudinal flexible ruler is fixedly connected to the middle of the lower end of the arm fixing band. The longitudinal flexible ruler is used for longitudinally measuring the length of the catheter. A first metal buckle is movably sleeved on the longitudinal flexible ruler, and the first metal buckle is magnetically connected and fixed in cooperation with the magnetic connection point. The front end of the transverse flexible ruler is fixed at the magnetic connection point. The transverse flexible ruler is used for transversely measuring the arm circumference length. A second metal buckle is movably sleeved on the transverse flexible ruler, and the second metal buckle is magnetically connected and fixed in cooperation with the magnetic connection point.

[0008] Furthermore, a storage bag is arranged on the arm fixing band, and the storage bag is used for storing and placing the longitudinal flexible ruler and the transverse flexible ruler.

[0009] Furthermore, the arm fixing band is of a rectangular structure, and the width of the arm fixing band is 10 cm.

[0010] Furthermore, the total length of the longitudinal flexible ruler is 60 - 80 cm.

[0014] Advantage 1: By providing the arm fixing band, the longitudinal flexible ruler and the transverse flexible ruler, the present invention can not only measure and use the catheter length in the longitudinal direction, but also effectively measure and use the arm circumference length in the transverse direction, improving the use function of the measuring ruler and making it more convenient for clinical operation by nursing staff.

[0015] Advantage 2: By providing the magnetic connection point on the arm fixing band and the first metal buckle on the longitudinal flexible ruler, the present invention can not only utilize the 10 cm width of the arm fixing band to accurately meet the requirement of measuring 10 cm upward from the cubital transverse crease, reducing measurement errors, but also ensure the vertical measurement direction of the longitudinal flexible ruler by using magnetic connection, further improving measurement accuracy.

[0022] The following further illustrates and describes the detailed embodiment of the present utility model with reference to the description of the drawings.

[0023] As Figures 1 to 4 shown, an external measuring ruler for PICC catheterization includes an arm fixing belt 1, a longitudinal flexible ruler 2, and a transverse flexible ruler 3. The arm fixing belt 1 is cooperatively wound and fixed on the arm. A storage bag 11 is provided on the arm fixing belt 1, and the storage bag 11 is used to store and place the longitudinal flexible ruler 2 and the transverse flexible ruler 3. The arm fixing belt 1 has a rectangular structure, the width of the arm fixing belt 1 is 10 cm, and magic tapes 12 are respectively provided at both ends of the arm fixing belt 1, and the arm fixing belt 1 is adhesively connected and fixed through the magic tapes 12.

[0024] As Figures 1 to 4 shown, a magnetic connection point 4 is provided in the middle of the upper end of the arm fixing belt 1. The front end of the longitudinal flexible ruler 2 is fixedly connected to the middle of the lower end of the arm fixing belt 1. The longitudinal flexible ruler 2 is used for longitudinally measuring the length of the catheter. The total length of the longitudinal flexible ruler 2 is 60 - 80 cm. A first metal buckle 21 is movably sleeved on the longitudinal flexible ruler 2. The first metal buckle 21 is magnetically connected and fixed in cooperation with the magnetic connection point 4. When measuring, the longitudinal flexible ruler 2 measures along the direction of the middle of the upper and lower ends of the arm fixing belt 1, so that the longitudinal flexible ruler 2 is perpendicular to the arm fixing belt 1 for measurement.

[0025] As Figures 1 to 4As shown, the front end of the transverse flexible ruler 3 is fixed at the magnetic connection point 4. The transverse flexible ruler 3 is used for horizontally measuring the arm circumference length. A second metal buckle 31 is movably sleeved on the transverse flexible ruler 3. The second metal buckle 31 is magnetically connected and fixed in cooperation with the magnetic connection point 4. The total length of the transverse flexible ruler 3 is 40 - 50 cm. When measuring, the transverse flexible ruler 3 is wound around the arm, and the measurement value is read at the magnetic connection point 4. The second metal buckle 31 is magnetically fixed to the magnetic connection point 4, making the data more accurate and stable when reading and recording, and improving the stability and accuracy of the measurement.

[0026] During use:

[0027] First, take out the longitudinal flexible ruler 2 and the transverse flexible ruler 3 from the storage bag 11 in the arm fixing band 1. Then, wear the arm fixing band 1 on the patient's arm and fix it by fitting and connecting with the magic tape 12 to complete the wearing and fixing of the arm fixing band 1. The lower edge of the arm fixing band 1 is located at the elbow joint of the arm. Since the width of the arm fixing band 1 is 10 cm, it can accurately facilitate the subsequent measurement of the arm circumference (the measurement position of the arm circumference is 10 cm above the elbow joint of the arm).

[0028] Then, wind the transverse flexible ruler 3 horizontally around the arm of the measurer, and magnetically connect and fix the second metal buckle 31 on the transverse flexible ruler 3 to the magnetic connection point 4 on the arm fixing band 1. At this time, read the data on the transverse flexible ruler 3 at the position of the magnetic connection point 4 to obtain the measured value of the arm circumference.

[0029] Then, pull up the longitudinal flexible ruler 2, and magnetically connect and fix the first metal buckle 21 to the magnetic connection point 4 on the arm fixing band 1 to keep the longitudinal flexible ruler 2 perpendicular to the arm fixing band 1. Then, continue to pull up the longitudinal flexible ruler 2 to measure the distance between the upper arm and the large vein to determine the length data of the catheterization.

[0030] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive improvement made to the present utility model using this concept should belong to the act of infringing the protection scope of the present utility model.
