Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a PICC medium-length catheter arm circumference measuring ruler. Background Art

[0002] The arm circumference of PICC medium-length catheters needs to be measured before catheterization, and it also needs to be measured every time it is replaced or when changing shifts. The arm circumference measuring ruler of PICC medium-length catheters is a medical tool used to accurately measure the circumference of the patient's upper arm. It is crucial for selecting the appropriate catheter length and fixed position. However, the existing arm circumference measuring ruler still has defects and deficiencies in some aspects that need to be improved:

[0003] For example, a PICC arm circumference measuring ruler with publication number CN214511156U includes an arm length ruler, the arm length ruler is divided into a rear fixed area and a front measuring area, the fixed area is an arc structure, the measuring area has a slide arranged along its length direction, the length of the slide is 10 cm, the end of the slide has a limit groove, the limit groove is arranged along the length direction of the slide, at least one elastic limit ball is arranged on the limit groove, a slider is slidably arranged on the slide groove, a limit block is fixed on the side wall of the slider, the limit block has a countersunk hole used in conjunction with the elastic limit ball, a detachable storage box is arranged on the upper surface of the slider, and an arm circumference soft ruler is wound in the storage box. The utility model can measure the arm length and arm circumference at the same time, avoid errors in the measurement process, and improve the measurement speed.

[0004] The existing arm circumference measuring ruler generally needs to select a position 10cm above the patient's elbow for measurement during the measurement of the arm circumference of a PICC medium-length catheter. However, in the process of measuring the arm circumference, there are certain discrepancies in the data measured by different measurers, resulting in certain inaccuracies in the measurement results.

[0005] Therefore, we proposed a PICC mid-length catheter arm circumference measurement ruler to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a PICC medium-length catheter arm circumference measuring ruler to solve the problem that different measurers' measured data have certain discrepancies, thus causing certain inaccuracies in the measurement results.

[0007] To achieve the above object, the utility model provides the following technical solution: a PICC medium-long catheter arm circumference measuring ruler, the upper side of the fixed soft belt is fixedly connected to a connecting ruler, and the upper side of the connecting ruler is fixedly connected to a measuring ruler body;

[0008] Velcro, which is fixedly connected to the fixed soft belt, and the fixed soft belt is also fixedly connected to the Velcro mother tape;

[0009] The docking hole is provided on the measuring ruler body, and a movable groove is also provided on the measuring ruler body.

[0010] Furthermore, the measuring ruler body is arranged in an inclined state, and the length of the measuring ruler body extends to 60CM to the right.

[0011] Furthermore, the right side width of the measuring ruler body is smaller than the minimum width of the docking hole, and the right side of the measuring ruler body can penetrate into the docking hole.

[0012] Furthermore, a limiting hose is fixedly connected inside the movable groove, and a sliding sleeve is nested and connected outside the limiting hose.

[0013] Furthermore, a buffer spring is fixedly connected between the sliding sleeve and the movable groove, and an observation rod is fixedly connected to the outer side of the sliding sleeve, and the observation rod is nested and connected to the outer side of the measuring ruler body.

[0014] Furthermore, the sliding sleeve forms an elastic structure through the buffer spring and the movable groove, and the observation rod forms a sliding structure through the sliding sleeve and the measuring ruler body.

[0015] Furthermore, the length of the connecting ruler is 10CM.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Medical staff can wrap the fixed soft belt around the patient's elbow. With the help of the Velcro and Velcro tape, the belt can be adjusted according to the patient's elbow circumference, so that the device can be worn more firmly on the patient's elbow.

[0018] 2. The length of the connecting ruler is 10CM. At this time, the measuring ruler can be placed 10CM above the patient's elbow without manual measurement by medical staff, which reduces the workload of manual measurement by medical staff and further reduces the errors caused by manual measurement;

[0019] 3. When the patient's arm circumference needs to be measured, the measuring ruler body needs to be manually placed around the patient's arm, and the outer side of the measuring ruler body needs to be passed through the inside of the docking hole. At this time, the measuring ruler body is tightened, and the patient's arm circumference can be recorded through the scale set on the measuring ruler body;

[0020] 4. When the arm circumference measurement is completed, the medical staff can manually move the observation rod, and the observation rod can move along the outside of the measuring ruler body. The medical staff can move the observation rod to the measured scale, and the patient's arm circumference value can be observed more conveniently and accurately through the observation rod;

[0021] 5. When the observation rod is moving, it will synchronously drive the sliding sleeve to limit along the limit hose. At the same time, with the assistance of the elastic force of the buffer spring itself, the stability of the observation rod during movement can be further improved, thereby improving the accuracy of data measurement.
