DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] Such as Figures 1-4As shown in the figure, a abdominal circumference measuring device of the present invention includes a tape measure 1, a first connecting member 2 and a second connecting member 3. A fixing member 4 is slidably disposed in the first connecting member 2, and an elastic component 5 is disposed between the fixing member 4 and the first connecting member 2. A first notch 21 is formed in the first connecting member 2, and a second notch 31 is formed in the second connecting member 3. The head of the tape measure 1 is located in the first notch 21 and fixedly connected to the fixing member 4. The tail of the tape measure 1 passes through the second notch 31 and is slidably connected to the second connecting member 3. An extrusion member 6 is disposed on the fixing member 4, and a pressing rod 32 is slidably disposed in the second notch 31. The extrusion member 6 is used to push the pressing rod 32 to move to extrude and fix the tape measure 1 in the second notch 31. During measurement, the tail of the tape measure 1 is pulled to compress the elastic component 5. When the elastic component 5 is compressed, the extrusion member 6 is driven to move. The extrusion member 6 pushes the pressing rod 32 to move to extrude the tape measure 1 in the second notch 31 until the elastic component 5 is compressed to the maximum position. The pressing rod 32 presses the tape measure 1 tightly, and the tape measure 1 cannot move any further. Medical staff can read the value of the tape measure 1 on the second connecting member 3 to obtain the abdominal circumference value of the patient, effectively avoiding the situation that different abdominal circumference values will appear due to different tightness degrees.
[0027] It should be noted that in this embodiment, a reading strip 33 is disposed at the end of the second connecting member 3, which is convenient for medical staff to read the value of the tape measure 1. And when the elastic component 5 is compressed to the maximum position, the length of the head of the tape measure 1 remaining in the first notch 21 should be as equal as possible to the distance from the reading strip 33 to the end of the first connecting member 2 to ensure the accuracy of the value at the reading strip 33.
[0028] In this embodiment, an installation cavity 22 is formed in the first connecting member 2. The elastic component 5 includes a rod body 51 and a spring 52. The two ends of the rod body 51 are respectively fixedly connected to the two ends of the installation cavity 22. The spring 52 is sleeved on the rod body 51. The fixing member 4 includes a first slider 41. The first slider 41 is located in the installation cavity 22 and slidably sleeved on the rod body 51. One end of the spring 52 is connected to the first slider 41, and the other end is connected to the inner end wall of the installation cavity 22. By setting the rod body 51 and the spring 52, when the tail of the tape measure 1 is pulled to extrude the patient's abdomen, the head of the tape measure 1 will be driven to slide in the first notch 21. When the head of the tape measure 1 moves, the fixing member 4 is driven to move, so that the first slider 41 slides in the installation cavity 22, so as to drive the extrusion member 6 to push the pressing rod 32 to move.
[0029] In this embodiment, the fixing member 4 further includes a fixing post 42. The first slider 41 is fixedly connected to the fixing post 42. A through groove 23 is provided between the installation cavity 22 and the first notch 21. The end of the fixing post 42 passes through the through groove 23 and is located within the first notch 21. A fixing hole 11 is formed at the head of the tape measure 1, and the tape measure 1 is fixedly sleeved on the fixing post 42 through the fixing hole 11. Through the fixing hole 11 and the fixing post 42, the fixing connection between the tape measure 1 and the fixing member 4 is realized. By providing the through groove 23, the maximum compression amount of the spring 52 is limited, so as to effectively ensure that the maximum compression amount of the spring 52 is located at the same position each time, ensuring the measurement accuracy.
[0030] It should be noted that in this embodiment, when the spring 52 is compressed to the maximum compression amount, it is best that the tape measure 1 fits on the patient's abdomen and slightly squeezes the abdomen without falling off. Therefore, the elastic force of the spring 52 should not be set too large to avoid excessive squeezing of the patient's abdomen and affecting the measurement accuracy.
[0031] In this embodiment, the pressing member 6 includes a push rod 61. A threaded hole 421 is formed in the fixing post 42. One end of the push rod 61 is threadedly connected to the threaded hole 421, and the other end is located within the second notch 31 for pushing the pressure rod 32 in the second notch 31 to move.
[0032] An integral block 62 is formed on the push rod 61. The diameter of the block 62 is larger than the diameter of the fixing post 42. By providing the block 62, the head of the tape measure 1 is blocked to prevent the head of the tape measure 1 from falling off. And by threadedly connecting the push rod 61 to the threaded hole 421, it is convenient to remove the block 62, so as to replace the tape measure 1.
[0033] In this embodiment, sliding grooves 34 are formed at both the upper and lower ends of the second notch 31. Second sliders 321 are integrally formed at both ends of the pressure rod 32, and the second sliders 321 are slidably arranged within the sliding grooves 34, realizing the sliding installation of the pressure rod 32 within the second notch 31.
[0034] The sliding groove 34 gradually inclines towards the side wall of the second notch 31 from the outlet end direction to the inlet end direction of the second notch 31. When the push rod 61 pushes the pressure rod 32 to move, the pressure rod 32 slides within the sliding groove 34 and gradually approaches the tape measure 1 within the second notch 31 until the pressure rod 32 squeezes and fixes the tape measure 1 within the second notch 31.
[0035] In this embodiment, guide posts 71 are rotatably arranged at the ends of both the first connecting member 2 and the second connecting member 3. The head of the tape measure 1 bypasses the guide posts 71 and enters the first notch 21, and the tail of the tape measure 1 bypasses the guide posts 71 and enters the second notch 31. By providing the guide posts 71, it is more smooth to pull the tape measure 1.
[0036] In this embodiment, a limiting rod 72 is provided in each of the first notch 21 and the second notch 31. The tape measure 1 is located inside the limiting rod 72, and the limiting rod 72 is used to limit the tape measure 1 to prevent the tape measure 1 from slipping out of the first notch 21 or the second notch 31.
[0037] In this embodiment, a jack 24 is formed on the side of the first connecting member 2 close to the second connecting member 3. A plug rod 35 is fixedly installed on the second connecting member 3, and the plug rod 35 is inserted into the jack 24. By providing the jack 24 and the plug rod 35, the first connecting member 2 and the second connecting member 3 can be combined together during use. Medical staff can hold the first connecting member 2 and the second connecting member 3 with one hand and pull the tail of the tape measure 1 with the other hand for measurement, which is convenient for medical staff to use. Magnetic sheets 73 are provided on the sides of the first connecting member 2 and the second connecting member 3 that are in contact with each other. By providing the magnetic sheets 73, when storing, the first connecting member 2 and the second connecting member 3 can be attracted together for convenient storage.
[0038] The usage method of an abdominal circumference measuring device of the present invention is as follows:
[0039] First, hold the first connecting member 2 by hand and wrap the second connecting member 3 around the patient's abdomen until the tape measure 1 surrounds the patient's abdomen.
[0040] Subsequently, insert the plug rod 35 of the second connecting member 3 into the jack 24 of the first connecting member 2.
[0041] Then, hold the first connecting member 2 and the second connecting member 3 with one hand and pull the tail of the tape measure 1 with the other hand for measurement.
[0042] During the process of pulling the tail of the tape measure 1, the tape measure 1 gradually adheres to the patient's abdomen. When the tape measure 1 adheres to the patient's abdomen and starts to squeeze the patient's abdomen, it will drive the head of the tape measure 1 to slide in the first notch 21. When the head of the tape measure 1 moves, it drives the fixing member 4 to move. During the movement of the fixing member 4, the first slider 41 slides in the mounting cavity 22, compressing the spring 52. At the same time, the fixing column 42 drives the push rod 61 to push the pressing rod 32 to slide in the chute 34 and gradually approach the tape measure 1 in the second notch 31. Continuously pull the tail of the tape measure 1 until the spring 52 is compressed to the maximum compression amount. At the same time, the pressing rod 32 squeezes and fixes the tape measure 1 in the second notch 31, locking the tape measure 1 so that the tape measure 1 cannot be pulled continuously.
[0043] Finally, separate the first connecting member 2 and the second connecting member 3, and read the value at the reading strip 33. After reading, manually move the pressing rod 32 to make the pressing rod 32 release the locking of the tape measure 1 for secondary measurement.
