[0002] The incidence of lymphedema after breast cancer surgery can be as high as 65%, causing swelling, pain, numbness, fatigue, and even functional impairment of the affected limbs. More than 90% of breast cancer patients will receive chemotherapy during the treatment period. For the safety of chemotherapy patients, chemotherapy patients need to have a central venous catheter, which will inevitably cause venous thrombosis. When venous thrombosis occurs in the patient's body, there will be symptoms such as swelling of the arm, increased skin temperature in the arm, and reddish or bluish skin on the arm. In order to improve the quality of care for patients with lymphedema and venous thrombosis, it is necessary to measure the patient's arm circumference regularly every day. By evaluating the change in arm circumference, it can be known whether the patient's arm is swollen, and symptoms can be detected and treated in time.

[0003] At present, a traditional tape measure is usually used to measure the arm circumference of a patient. However, when measuring the arm circumference each time, the tape measure is easily tightened to a different degree, which in turn causes the tape measure to tighten the patient's arm to a different degree, resulting in the arm circumference measurement value being unable to accurately reflect the changes in the patient's arm circumference. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an arm circumference measuring device which can make the arm circumference measurement value more accurately reflect the arm circumference change of the patient.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an arm circumference measuring device, comprising a handle, an arc-shaped through groove formed by being recessed downward from the upper end surface of the handle and penetrating the front and rear side surfaces of the handle, a hole formed in the handle and connected to the upper end surface of the handle at a position corresponding to the right edge of the arc-shaped through groove, a lower end of which is connected to the left side surface of the handle, a connecting part slidably arranged on the left side surface of the handle and located at the lower side of the hole, a sliding part slidably arranged on the left side surface of the handle and located at the lower side of the connecting part, an elastic member connected between the connecting part and the sliding part, a scale line arranged on the left side surface of the handle along the up-down direction, and a first soft ruler fixedly connected to the left edge of the arc-shaped through groove at one end; the other end of the first soft ruler passes through the hole from top to bottom and is located below the connecting part, and the position of the first soft ruler corresponding to the connecting part is fixedly connected to the connecting part.

[0006] Furthermore, the connecting portion includes a connecting block slidably arranged on the left side of the handle, a through hole formed on the connecting block and penetrating the upper and lower sides of the connecting block, and a holding portion for pressing and fixing the first soft ruler on a side wall of the through hole close to the handle; the upper end of the elastic member is fixedly connected to the connecting block, and the lower end is fixedly connected to the sliding portion.

[0007] Furthermore, a screw hole is formed on the connecting block, one end of which is connected to a side surface of the connecting block facing away from the handle and the other end of which is connected to the through hole. The pressing portion includes a bolt screwed into the screw hole, a ball socket recessed inward from the end surface of the screw-in end of the bolt, and a ball rollingly fitted in the ball socket, and the screw-in end of the bolt faces the handle.

[0008] Furthermore, the left side surface of the handle is recessed inward to form a vertically arranged slide groove, and the slide groove is located at the lower side of the channel; the connecting part also includes a first sliding block fixed on the connecting block and slidably fitted in the slide groove.

[0009] Furthermore, the sliding portion includes a second sliding block slidably fitted in the sliding groove and a moving block fixedly mounted on the second sliding block, and the upper end of the elastic member is fixedly connected to the connecting block, and the lower end is fixedly connected to the moving block.

[0010] Furthermore, a second soft ruler is fixedly provided on the front side of the handle at a position corresponding to the bottom of the arc-shaped through groove, and the second soft ruler is arranged along the front-to-back direction.

[0011] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] like Figure 1 and Figure 2As shown, an arm circumference measuring device comprises a handle 1, an arcuate through groove 2, a channel 3, a connecting portion, a sliding portion, an elastic member 4, a scale line 5 and a first soft ruler 6, wherein the arcuate through groove 2 is formed by being recessed downward from the upper end surface of the handle 1, the arcuate through groove 2 passes through the front and rear side surfaces of the handle 1, the channel 3 is formed in the handle 1, the upper end of the channel 3 is connected to the position of the upper end surface of the handle 1 corresponding to the right edge of the arcuate through groove 2, the lower end of the channel 3 is connected to the left side surface of the handle 1, the connecting portion can be slidably arranged on the left side surface of the handle 1 up and down, the connecting portion is located at the lower side of the channel 3, the sliding portion can be slidably arranged on the left side surface of the handle 1 up and down, the sliding portion is located at the lower side of the connecting portion, the elastic member 4 is connected between the connecting portion and the sliding portion, in this embodiment, the elastic member 4 is an elastic rubber rope, it can be understood that in other embodiments, the elastic member 4 can also be a spring. The scale line 5 is arranged on the left side of the handle 1 along the up-down direction, one end of the first soft ruler 6 is fixedly connected to the left edge of the arc-shaped through groove 2, and the other end of the first soft ruler 6 passes through the channel 3 from top to bottom and is located below the connecting part, and the position of the first soft ruler 6 corresponding to the connecting part is fixedly connected to the connecting part.

[0023] The initial state of the arm circumference measuring device of the utility model is: one end of the first soft ruler 6 is fixedly connected to the left edge of the arc-shaped through groove 2, the other end of the first soft ruler 6 passes through the upper end of the hole 3 into the hole 3, and is located below the connecting part after passing through the lower end of the hole 3, the position of the first soft ruler 6 corresponding to the connecting part is fixedly connected to the connecting part, and the arc-shaped through groove 2 and the first soft ruler 6 together form a ring.

[0024] When it is necessary to measure the arm circumference of the patient, the nursing staff holds the handle 1 and allows the patient's arm to pass through the ring until the first soft ruler 6 is located on the patient's upper arm and the first soft ruler 6 is 10 cm away from the elbow. Then the sliding part is slid on the handle 1 away from the patient's arm. During the sliding process of the sliding part, the elastic member 4 can be stretched and the connecting part can be driven to slide away from the patient's arm. After the sliding part slides a certain distance, the first soft ruler 6 can be tightened on the patient's arm under the tension of the elastic member 4. At this time, the measured value of the patient's arm circumference and the length value of the elastic member 4 after being stretched are read and recorded. The measured value of the patient's arm circumference is the sum of the arc length of the arc-shaped through groove 2 and the length of the part of the first soft ruler 6 tightened on the patient's arm. The arc length of the arc-shaped through groove 2 can be obtained by measuring in advance, and the length of the part of the first soft ruler 6 tightened on the patient's arm can be obtained by observing the scale on the first soft ruler 6. The length value of the elastic member 4 after being stretched can be obtained by referring to the scale line 5 on the left side of the handle 1. After the measurement is completed, the slide is released and the patient's arm can then be withdrawn from the loop.

[0025] The above steps are used each time the arm circumference of the patient's arm is measured. It is only necessary to ensure that the elastic member 4 is stretched to the same length each time the measurement is made, so that the tension provided by the elastic member 4 to the first soft ruler 6 is the same, and the first soft ruler 6 has the same degree of tightening on the patient's arm. Each time the arm circumference measuring device of the utility model is used to measure the arm circumference of the patient, it can be ensured that the first soft ruler 6 has the same degree of tightening on the patient's arm, so that the arm circumference measurement value can more accurately reflect the changes in the patient's arm circumference.

[0026] like Figure 2 and Figure 3 As shown, the connecting portion includes a connecting block 7, a through hole 8 and a holding portion. The connecting block 7 can be slidably arranged on the left side of the handle 1 up and down. The through hole 8 is formed on the connecting block 7. The through hole 8 passes through the upper and lower sides of the connecting block 7. The holding portion is used to hold and fix the first soft ruler 6 on a side wall of the through hole 8 close to the handle 1; the upper end of the elastic member 4 is fixedly connected to the connecting block 7, and the lower end of the elastic member 4 is fixedly connected to the sliding portion.

[0027] The other end of the first flexible ruler 6 is passed through the through hole 8 and is located below the connecting block 7. The first flexible ruler 6 is then pressed and fixed to a side wall of the through hole 8 close to the handle 1 by the pressing portion. At this time, the first flexible ruler 6 can be fixedly connected to the connecting portion at a position corresponding to the connecting portion.

[0028] A screw hole 9 is formed on the connecting block 7, one end of the screw hole 9 is connected to a side of the connecting block 7 facing away from the handle 1, and the other end of the screw hole 9 is connected to the through hole 8. The pressing portion includes a bolt 10, a ball socket 11 and a ball 12. The bolt 10 is screwed into the screw hole 9, and the ball socket 11 is recessed inward from the end surface of the screw-in end of the bolt 10. The ball 12 rolls and fits in the ball socket 11, and the screw-in end of the bolt 10 faces the handle 1.

[0029] After the other end of the first flexible ruler 6 passes through the through hole 8, the first flexible ruler 6 is located between the ball 12 and a side wall of the through hole 8 close to the handle 1. Then, the bolt 10 is rotated in the screw hole 9 to move the bolt 10 toward the direction of the handle 1, and the bolt 10 can drive the ball 12 to press and fix the first flexible ruler 6 on a side wall of the through hole 8 close to the handle 1. With this structure, the pressing part can press and fix the first flexible ruler 6 on a side wall of the through hole 8 close to the handle 1. When the first flexible ruler 6 is pressed and fixed on a side wall of the through hole 8 close to the handle 1, the ball 12 with a smooth surface contacts the first flexible ruler 6, and the first flexible ruler 6 is not easily worn.

[0030] The bolt 10 can be rotated in the screw hole 9 to move the bolt 10 away from the handle 1, and the bolt 10 can drive the ball 12 to loosen the pressure on the first soft ruler 6. At this time, the first soft ruler 6 can be pinched at the position corresponding to the upper end of the channel 3 and pulled upward to move the other end of the first soft ruler 6 upward, or the other end of the soft ruler can be pinched and pulled downward to adjust the length of the portion of the soft ruler located on the upper side of the handle 1, that is, the size of the collar can be adjusted, so that the arm circumference measuring device of the utility model can measure a larger range. After the size of the collar is adjusted, the bolt 10 is rotated in the screw hole 9, so that the bolt 10 drives the ball 12 again to press and fix the first soft ruler 6 on the side wall of the through hole 8 close to the handle 1.

[0031] It can be understood that the pressing portion is not limited to the structure described above. For example, in some embodiments, the pressing portion can also only include a bolt 10 screwed into the screw hole 9. The bolt 10 is rotated in the screw hole 9 to move toward the handle 1. The screwed end of the bolt 10 can also press and fix the first soft ruler 6 on a side wall of the through hole 8 close to the handle 1. With this structure, the pressing portion can also press and fix the first soft ruler 6 on a side wall of the through hole 8 close to the handle 1.

[0032] The left side of the handle 1 is recessed inward to form a slide groove 13, which is arranged vertically and located at the lower side of the channel 3; the connecting portion also includes a first slider 14, which is fixed on the connecting block 7 and slidably fits in the slide groove 13. The first slider 14 can slide up and down in the slide groove 13, and the connecting block 7 can slide up and down with the first slider 14. With this structure, the connecting portion can be slidably arranged on the left side of the handle 1.

[0033] The sliding part includes a second slider 15 and a moving block 16. The second slider 15 is slidably matched in the slide groove 13. The moving block 16 is fixed on the second slider 15. The upper end of the elastic member 4 is fixedly connected to the connecting block 7, and the lower end of the elastic member 4 is fixedly connected to the moving block 16. The second slider 15 can slide up and down in the slide groove 13, and the moving block 16 can slide up and down with the second slider 15. With this structure, the sliding part can be slidably arranged on the left side of the handle 1.

[0034] like Figure 1 As shown, a second soft ruler 17 is fixedly provided on the front side of the handle 1 at a position corresponding to the bottom of the arc-shaped through groove 2, and the second soft ruler 17 is arranged along the front-back direction.

[0035] When the patient's arm is passed through the collar, the front side of the handle 1 is facing away from the patient's shoulder, and the second soft ruler 17 is located on the side of the handle 1 facing away from the patient's shoulder. After the patient's upper arm is located in the collar, the distance between the front side of the handle 1 and the patient's elbow fossa can be measured by the second soft ruler 17. The distance between the front side of the handle 1 and the front edge of the first soft ruler 6 can be obtained by measuring in advance. The distance between the front side of the handle 1 and the front edge of the first soft ruler 6 and the distance between the front side of the handle 1 and the patient's elbow fossa are the distance between the first soft ruler 6 and the patient's elbow fossa. By setting the second soft ruler 17, it is convenient to locate the patient's arm circumference measurement position, so that the repeatability of each measurement position is good.

[0036] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
