Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary tools, and in particular to an improved arm circumference measuring tape. Background Technology

[0002] When nursing staff maintain patients with indwelling PICC lines, they need to measure the patient's arm circumference. The measurement involves placing the zero mark of the ruler at the elbow crease, measuring 10cm upwards from the crease, and then measuring the arm circumference 10cm above that point. Currently, clinical tools mostly consist of ordinary measuring tapes or rulers, lacking a direct positioning ruler. Nurses must first use the ruler to position themselves 10cm above the elbow crease, then hold the ruler in place with one hand and rotate it before measuring the arm circumference. This operation is extremely inconvenient and cumbersome, and the positioning point is prone to shifting, resulting in inaccurate arm circumference measurements.

[0003] A medical arm circumference measuring tool, disclosed in CN 215534375 U, includes a measuring tape box containing two arm length measuring tapes. The measuring tape box has openings at its top and bottom, from which the two arm length measuring tapes extend. Each arm length measuring tape has an arm circumference measuring tape attached to its end. Both the arm circumference measuring tape and the arm length measuring tape are flexible measuring tapes. An arm wrapping bandage is attached to the measuring tape box. This medical arm circumference measuring tool causes minimal pressure on the skin during measurement, minimizing pain for the patient. It can record arm length data. During each measurement, the measuring tape box is aligned with the skin crease of the patient's elbow crease. Quantitatively controlling the extension of the arm length measuring tapes each time precisely determines the measurement position, ensuring consistent measurement and facilitating the recording of arm circumference changes. It is highly efficient and accurate.

[0004] However, the measuring tools in this application are rather cumbersome to use, and the storage box is quite bulky and inconvenient to take out. Summary of the Invention

[0005] To address the aforementioned problems, this utility model aims to provide an improved arm circumference measuring tape. By setting a storage box on the tape body and storing all the measuring structures used to measure arm circumference in the storage box, the measured structures are made very small in size, easy to take out, and simple and convenient to use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An improved arm circumference measuring tape, characterized in that: it includes a measuring tape body, a storage box is provided on one side of the measuring tape body, and a measuring structure is provided inside the storage box;

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Please see Figures 1-5 This application discloses an improved arm circumference measuring tape, including a measuring tape body 1, a storage box 2 on one side of the measuring tape body 1, and a measuring structure inside the storage box 2.

[0026] It should be noted that the measuring tape body 1 is made of a steel sheet wrapped with a layer of silicone, which will not scratch the arm, can be worn on the wrist as a decoration, and can be used repeatedly for a long time. It can be cleaned and disinfected when it gets dirty.

[0027] A hollow storage box 2 made of medical-grade plastic is glued to one side of the measuring tape body 1. The storage box 2 contains a measuring structure, such as... Figure 1 As shown, when no measurement is needed, the measuring structure is stored in the storage box 2. The bent measuring tape body 1 and the storage box 2 are very small in size and easy to carry. If there are many patients to be measured, medical staff can put the measuring tape body 1 in their work clothes pocket, which is not only portable but also allows them to quickly take out the measuring tape body 1 from their work clothes pocket to measure different patients.

[0028] When nursing staff maintain patients with indwelling PICC lines, they need to measure the patient's arm circumference. During measurement, the nursing staff first place the zero mark of the ruler at the elbow crease, measure 10cm upwards from the elbow crease, and then measure the arm circumference 10cm above the elbow crease. Therefore, the measuring structure of this application includes a positioning component located inside the storage box, and an arm circumference measuring component connected to the positioning component.

[0029] The storage box 2 has a first box 3 and a second box 4 inside. The second box 4 is arranged adjacent to the first box 3. The positioning component is located inside the first box 3, and the arm circumference measuring component is located inside the second box 4.

[0030] Specifically, the outer wall of box 3 is adhered to the inside of storage box 2, and box 4 is movably fitted inside storage box 2, as shown below. Figure 2 and Figure 3 As shown, when measurement is required, pull the second box 4 out of the storage box 2 by 10cm, and then use the internal structure of the second box 4 to measure the arm circumference.

[0031] The positioning components include a first movable shaft 7 and a first measuring tape 5 sleeved on the first movable shaft 7. The end of the first measuring tape 5 is connected to the outer wall of the second box 4. A slot is provided on the bottom of one side of the first box 3.

[0032] Specifically, the two ends of the first movable shaft 7 are movably sleeved on the inner wall of the corresponding position of the first box 3, the first measuring tape 5 is wound around the first movable shaft 7, and the initial end of the first measuring tape 5 is bonded and fixedly connected to the first movable shaft 7, and the end of the first measuring tape 5 passes through the slot and is bonded and fixedly connected to the outer wall of the second box 4.

[0033] It should be noted that the No. 1 measuring tape (5) is a rigid stainless steel measuring tape with inherent elasticity. When fully extended, the total length of the No. 1 measuring tape protruding between storage box 2 and box 2 is 10cm. The upper surface of the No. 1 measuring tape (5) is engraved with graduations and numerical markings (not shown), allowing caregivers to quickly measure 10cm upwards from the elbow crease without needing to find the zero mark first, making it very convenient and quick. When not in use, the No. 1 measuring tape (5) automatically returns to its original position.

[0034] The arm circumference measuring component includes a second movable shaft 8 and a second measuring tape 6 fitted onto the second movable shaft 8. One end of the second movable shaft 8 extends to the outside of the second housing 4 and is connected to a rocker arm 9. The rocker arm 9 can not only serve as a handle to pull out the second housing 4, but also as a winding structure for winding up the second measuring tape 6 fitted onto the second movable shaft 8.

[0035] The front bottom of the second box 4 has a first slot 10, and the rear bottom has a second slot 11. The end of the second measuring tape 6 is provided with a limiting rod 12.

[0036] like Figure 5 As shown, when measuring 10cm upwards from the elbow crease, and then measuring the arm circumference, the limiting rod 12, which is glued and fixed to the end of the second measuring tape 6, can be pulled. The limiting rod 12 will cause the second measuring tape 6 to slowly wrap around the arm circumference to be measured. Then, the limiting rod 12 is placed in the second slot 11, and the direction of the limiting rod 12 is rotated so that the limiting rod 12 can be just locked in the second slot 11. Then the reading can be taken.

[0037] It should be noted that the No. 2 measuring tape 6 is made of a composite of fiberglass and PVC plastic. It is soft and skin-friendly, and will not scratch the patient's arm. Furthermore, the reading at the limit rod 12 of the No. 2 measuring tape 6 in this application starts from 5cm, subtracting the length of the storage box 2, making the arm circumference measured by the No. 2 measuring tape 6 more accurate. And as... Figure 4 and Figure 5 As shown, the extension directions of measuring tape 5 (size 1) and measuring tape 6 (size 2) are perpendicular. They will not interfere with each other. Example 1

[0038] When using the improved arm circumference measuring tape of this application to maintain a patient with a PICC, the operation is simple: locate the elbow crease, then attach the measuring tape body 1 as a positioning ruler to the patient's elbow crease. Pull the rocker arm 9 to pull the second box 4 out of the storage box 2. Since the outer wall of the second box 4 is fixedly connected to the first measuring tape 5, it will pull the first measuring tape 5 out as well. When the first measuring tape 5 can no longer be pulled, it indicates that the measurement is 10cm above the elbow crease. Then, pull the limiting rod 12 on the outside of the second box 4, causing the limiting rod 12 to slowly wrap the second measuring tape 6 around the arm circumference to be measured. Place the limiting rod 12 in the second slot 11 and rotate it so that it is properly engaged in the second slot 11. Then, take the measurement. After taking the reading, the second movable shaft 8 can be rotated in the opposite direction by rotating the reverse rocker 9, thereby rewinding the second measuring tape 6. Then, the first measuring tape 5 is returned to its original position, the second box 4 is put back into the storage box 2, and the measuring tape body 1 is put away for future use. Example 2

[0039] The operation method of this embodiment is the same as that of embodiment 1. The only difference is that this embodiment can measure the arm circumference of both upper limbs of patients with upper limb venous thrombosis, and then compare the changes in arm circumference of both upper limbs to dynamically track the thrombosis status of the patients.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
