Description

Technical Field

[0001] The utility model relates to the technical field of medical machinery, in particular to a lymphedema arm circumference measuring combination ruler. Background Art

[0002] Upper limb lymphedema is a common complication after breast cancer surgery. While milder symptoms can be alleviated by establishing collateral circulation, more severe symptoms can negatively impact quality of life and even prevent patients from functioning normally. Currently, upper limb lymphedema can be assessed by measuring arm circumference, enabling early detection and treatment. Currently, a non-elastic, flexible ruler is used to measure the circumference of both upper limbs at the elbow crease, 10 cm above the elbow crease, 10 cm below the elbow crease, the wrist crease, 5 cm above the wrist crease, and the base of the thumb. Lymphedema is diagnosed based on these measurements. This simple measurement method requires only a ruler and can be performed at home. However, the ruler's position is difficult to maintain, requiring assistance from the patient, resulting in slower measurement efficiency. Therefore, a combination ruler for measuring arm circumference for lymphedema is urgently needed to address this issue. Utility Model Content

[0003] In order to solve the technical problem that the existing ruler is difficult to fix in place and requires the assistance of others to measure the arm circumference of lymphedema, resulting in slow measurement efficiency, the utility model provides a combination ruler for measuring the arm circumference of lymphedema. The ruler has a simple structure and is fixed by Velcro surfaces and Velcro adhesive surfaces, which makes it convenient for people to measure and speeds up the measurement.

[0004] The utility model provides a lymphedema arm circumference measurement combination ruler, comprising at most three soft rulers, each of the soft rulers being provided with a marking window and a Velcro surface at the head, the marking window being located on the side of the millimeter scale line on the soft ruler, marking lines being provided above and below the marking window, the marking lines being connected to the marking window and being perpendicular to the marking window, the Velcro surface being located on the side of the marking window away from the millimeter scale line, the tail of each soft ruler being provided with an observation window and a Velcro surface, the observation window being located above the millimeter scale line, the Velcro surface and the Velcro surface being located on different surfaces of the soft ruler and being adapted to each other; each soft ruler being provided with a fixing strip, the fixing strip being detachably connected to a connecting strip.

[0005] Furthermore, there are three tape measures, of which the outer tape measure is set as the first tape measure, the tape measure in the middle is set as the second tape measure, and the third tape measure is set as the third tape measure. The width of the first tape measure is 1.5 cm, and the widths of the second and third tape measures are 1 cm.

[0006] Furthermore, the first soft ruler is used to measure the base of the thumb, and the length of the millimeter scale line of the first soft ruler is 30 cm.

[0007] Furthermore, the first and second soft rulers are used to measure the wrist crease and a position 5 cm above the wrist crease, respectively. The first and second soft rulers are both fixedly connected to the connecting belt, and the length of the millimeter scale lines of the first and second soft rulers is 30 cm.

[0008] Furthermore, the first, second and third soft rulers are used to measure the elbow crease, a position 10 cm above the elbow crease and a position 10 cm below the elbow crease, respectively. The first, second and third soft rulers are all fixedly connected to the connecting belt, and the length of the millimeter scale lines of the first, second and third soft rulers is 40 cm.

[0009] Furthermore, each of the fixing strips is provided with a concealed female buckle and a concealed male buckle at both ends, and the connecting strip is evenly provided with a plurality of fixing hole groups, each of which includes two fixing holes oppositely disposed on the connecting strip, and the concealed female buckle and the male buckle respectively pass through the two fixing holes and engage.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 5As shown, a combination ruler for measuring arm circumference for lymphedema comprises up to three soft rulers 1. Each ruler 1 has a marking window 11 and a Velcro surface 13 at its head. The marking window 11 is located lateral to the millimeter scale on the ruler 1. Marking lines 12 are provided above and below the marking window 11, connecting to and perpendicular to the marking window 11. The Velcro surface 13 is located on the side of the marking window 11 away from the millimeter scale. The tail of each ruler 1 has an observation window 14 and a Velcro surface 15. The observation window 14 is located above the millimeter scale. The Velcro surface 15 and the Velcro surface 13 are located on different sides of the ruler 1 and are compatible with each other. Each ruler 1 is provided with a fixing strip 2, which is detachably connected to a connecting strip 3. The marking window 11 can be circular or square in structure; the observation window 14 is a long strip. The three tape measures 1 are used as needed. When using only one tape measure 1, the connecting strap 3 is not required. A user marks a point on the user's upper limb or palm through the marking window 11. A hook-and-loop cover 15 is bonded and fixed to the hook-and-loop cover 13. The observation window 14 is now directly above the marking line 12, allowing the user to see the marking line 12 through the observation window 14. The marking line 12 and the marking point are coaxial, and the millimeter scale value on the tape measure 1 corresponding to the marking line 12 is the measured value. The measured value is compared with the normal value to determine whether the user has upper limb lymphedema. To avoid the influence of the added thickness of the hook-and-loop cover 13 and the hook-and-loop cover 15 on the measured value, the thickness of the hook-and-loop cover 13 and the hook-and-loop cover 15 is generally set to 1-2 mm. When comparing values, the measured value can be subtracted from the thickness of the hook-and-loop cover 13 or the hook-and-loop cover 15 and then compared with the normal value.

[0024] The combined ruler of this embodiment has a simple structure. The tape measure 1 is fixed by the Velcro surface 15 and the Velcro sticky surface 13, which makes it convenient for people to measure and speeds up the measurement.

[0025] There are three tape measures, with the outer tape measure 1 being the first tape measure, the middle tape measure 1 being the second tape measure, and the third tape measure 1 being the third tape measure. In this embodiment, the width of the first tape measure is 1.5 cm, while the widths of the second and third tape measures are 1 cm. Specifically, the distance between the marking window 11 on the first tape measure and the top edge of the first tape measure is the same as the distance between the marking window 11 on the first tape measure and the bottom edge of the first tape measure. The marking window 11 on the second tape measure can be located at the center of the head or at the top edge of the second tape measure; the marking window 11 on the third tape measure can be located at the center of the head or at the bottom edge of the third tape measure. In this embodiment, the first tape measure can be used alone, together with the second tape measure, or together with the first, second, and third tape measures.

[0026] Of course, when the combination ruler of this embodiment is generally used, the Velcro adhesive surface 13 and the Velcro veneer surface 15 can be bonded and fixed to the upper limbs or palms of a person. Figure 2 When used alone, the first ruler is used to measure the base of the thumb. The millimeter scale line on the first ruler is 30 cm long. The first ruler is wrapped around the base of the thumb. A user draws a mark on the palm of the hand through the marking window 11. The Velcro surface 15 is bonded and fixed to the Velcro surface 13. At this time, the observation window 14 is located directly above the mark line 12. The mark line 12 can be seen through the observation window 14. The mark line 12 and the mark point are coaxial. The millimeter scale value on the first ruler corresponding to the mark line 12 is the measurement value.

[0027] See also Figure 3 When the first and second rulers are used together, they are both fixedly connected to the connecting strap 3, which is necessary. The first and second rulers are used to measure the wrist crease and a position 5 cm above the wrist crease, respectively. The millimeter scale lines on the first and second rulers are 30 cm long. It is worth noting that the position 5 cm above the wrist crease is where the top edge of the second ruler is located. The distance between the marking window 11 on the first ruler and the top edge of the second ruler is 5 cm. The first tape measure is wrapped around the transverse wrist crease of the upper limb, and the second tape measure is wrapped around a position 5 cm above the transverse wrist crease. The person draws a mark point on the transverse wrist crease of the upper limb through the marking window 11, and the Velcro surface 15 is bonded and fixed to the Velcro surface 13. At this time, the observation window 14 is located directly above the mark line 12. The mark line 12 can be seen through the observation window 14. The mark line 12 and the mark point are on the same axis, and the millimeter scale value on the first tape measure corresponding to the mark line 12 and the millimeter scale value on the second tape measure corresponding to the mark line 12 are the measurement values.

[0028] See also Figure 1 When the first, second, and third rulers are used together, they are all fixedly connected to a connecting belt 3, which is required. The first, second, and third rulers are used to measure the elbow crease, a position 10 cm above the elbow crease, and a position 10 cm below the elbow crease, respectively. Connecting belt 3 is fixedly connected between the first and second rulers, and between the first and third rulers. The millimeter scale lines on the first, second, and third rulers are 40 cm long. It is worth noting that the upper edge of the second ruler is located 10 cm above the elbow crease, and the lower edge of the third ruler is located 10 cm below the elbow crease. The distance between the marking window 11 of the first ruler and the upper edge of the second ruler is 10 cm, and the distance between the marking window 11 of the first ruler and the lower edge of the third ruler is 10 cm. The first tape measure is wrapped around the elbow crease of the upper limb, the second tape measure is wrapped around 10 cm above the elbow crease, and the third tape measure is wrapped around 10 cm below the elbow crease. Similarly, the millimeter scale value on the first tape measure corresponding to the marking line 12, the millimeter scale value on the second tape measure corresponding to the marking line 12, and the millimeter scale value on the third tape measure corresponding to the marking line 12 are the measured values. This combination ruler of this embodiment can measure different positions of the upper limb in a single measurement, thereby speeding up the measurement process.

[0029] As an embodiment, each of the fixing strips 2 is provided with a concealed female buckle 21 and a concealed male buckle 22 at both ends. The connecting strip 3 is evenly provided with a plurality of fixing hole groups, each of which includes two fixing holes arranged opposite to each other on the connecting strip 3. The concealed female buckle 21 and the concealed male buckle 22 are respectively passed through the two fixing holes and engaged. After the concealed female buckle 21 and the concealed male buckle 22 on the fixing strip 2 are respectively passed through the two fixing holes and engaged, the fixing strip 2 is fixedly connected to the connecting strip 3, thereby securing the connecting strip 3 to the tape measure 1 provided with the fixing strip 2. Figure 4 The length of one end of the fixed strip 2 where the hidden button female buckle 21 is located is greater than the length of one end of the fixed strip 2 where the hidden button male buckle 22 is located, which further facilitates the engagement of the hidden button female buckle 21 and the hidden button male buckle 22.

[0030] As an embodiment, each of the tape measure 1 is provided with millimeter scale lines on the front, the marking lines 12 and the hook and loop adhesive surface 13 are located on the front of the tape measure 1, and the hook and loop adhesive surface 15 and the fixing strip 2 are located on the back of the tape measure 1. When the tape measure 1 is wrapped around the measuring position of the upper limb of a person, the hook and loop adhesive surface 13 and the hook and loop adhesive surface 15 are bonded and fixed.

[0031] Furthermore, the back of the tape measure 1 is provided with a Velcro surface, and the fixing strip 2 is provided with a Velcro surface, and the fixing strip 2 can be fixed to the tape measure 1 by adhesive fixation. When only one tape measure 1 is used and the connecting belt 3 is not needed, the fixing strip 2 on the tape measure 1 can also be removed.

[0032] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, it is of course possible to easily make other implementation methods by replacing or changing the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of the present invention should be included in the scope of the patent application of the present invention.
