Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring tools, specifically a measuring tool with bidirectional scale. Background Technology
[0002] Measurement tools refer to instruments or methods used to measure, evaluate or compare a thing or phenomenon using quantitative standards or parameters. Injection usually requires the use of infusion connectors and transparent catheters. With the development of medicine, the types, functions and structures of infusion connectors have become increasingly diversified, which also puts forward higher requirements for our medical staff's operation.
[0003] Existing measuring tools, such as graduated cylinders and measuring cups, are relatively simple in design and are mainly used for measuring static liquids. However, for flowing liquids in transparent tubes, due to the transparency and fluidity of the liquid, it is difficult to accurately read the volume or flow rate of the liquid when using simple measuring tools.
[0004] To overcome the above-mentioned defects, the prior art (Chinese patent application number: 00802457.X, application date: September 5, 2000) discloses an apparatus for measuring at least one parameter of a medium flowing in a pipeline. This measuring apparatus achieves the purpose of improving the measurement results through a simple method, which is to deflect liquid and / or solid particles around the measuring element by using a protective grid.
[0005] While existing technologies can measure the medium flowing in pipelines, they cannot be viewed and read in a timely manner, resulting in poor accuracy in measuring the distance the medium moves in the pipeline. Furthermore, the lack of a fixed structure makes it impossible to securely install the pipeline.
[0006] Therefore, we proposed a measurement tool with a two-way scale that can effectively solve the above problems. Utility Model Content
[0007] The purpose of this invention is to provide a measuring tool with bidirectional scales to solve the problems mentioned in the background art, such as the inability to view and read the data in a timely manner, resulting in poor measurement accuracy of the distance traveled by the medium flowing in the pipeline, and the lack of a fixed structure to fix the pipeline in place.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a measuring tool with bidirectional scale, including a scale and an infusion connector, wherein a scale body is provided on the front and back of the scale, and two threaded holes are symmetrically opened on the back of the upper and lower sides of the scale, and a groove is provided inside the back of the scale body.
[0009] The scale is movably connected to two mounting sleeves. Each mounting sleeve has internal threads on both the upper and lower sides connected to bolts. Fixing sleeves are fixedly installed on both sides of the mounting sleeve.
[0010] The fixed cylinder has a groove inside, and a sliding plate is installed inside the groove. A spring is fixedly installed at the rear of the sliding plate. A telescopic rod is fixedly connected to the front of the spring. A limit plate is fixedly installed on the front of the telescopic rod. A protective pad is fixedly connected to the inner wall of the limit plate.
[0011] As a preferred technical solution of this application, a transparent catheter is detachably connected to the right side of the infusion connector, and the end of the transparent catheter passes through the limiting plate. A thumb clip is fitted on the outer wall of the left side of the transparent catheter, and a moving groove is opened on the inner wall of the front and rear sides of the thumb clip.
[0012] As a preferred technical solution of this application, the scale and the groove are integrated, and the scale is made of transparent acrylic material. The groove and the transparent guide tube are detachably connected. The use of acrylic material for the scale provides high transparency, ensuring good visibility and accurate measurement.
[0013] As a preferred technical solution of this application, the slide plate and the slide groove are slidably connected, and the slide plate, the spring and the telescopic rod are tightly fitted together. By manually moving the limiting plate outward in sequence, the limiting plate drives the slide plate connected to the telescopic rod to slide inward in the corresponding slide groove, thereby compressing the spring during the sliding process of the slide plate.
[0014] As a preferred technical solution of this application, the limiting plate and the transparent guide tube are matched, and the limiting plate is set as a semi-circular arc structure. Due to the rebound force of the spring, the sliding plate and the telescopic rod connected thereto move outward, so that the telescopic rod drives the protective pad connected to the limiting plate to fit against the transparent guide tube.
[0015] As a preferred technical solution of this application, the limiting plate and the protective pad are fixedly connected, and the protective pad is made of silicone. Because the protective pad is made of silicone, it has excellent flexibility, wear resistance and corrosion resistance, which can better fit on the transparent conduit and reduce damage to its surface.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This measuring tool with bidirectional graduations, featuring a scale and dial indicator, allows for precise measurement of the distance colored liquid travels within a transparent conduit. It also includes a mounting sleeve and a limiting plate to securely install transparent conduits of different diameters, facilitating subsequent measurement and testing. Furthermore, a protective pad is included to secure and protect the transparent conduit. Details are as follows:
[0018] 1. A scale and dial indicator body are provided. Through the cooperation of the infusion connector, external syringe, transparent catheter, scale and dial indicator body, the distance of colored liquid movement in the transparent catheter can be accurately measured.
[0019] 2. An installation sleeve and a limiting plate are provided. The installation sleeve, bolts, threaded holes, limiting plate, telescopic rod, sliding plate, slide, spring, scale and groove work together to facilitate the fixed installation of transparent guide tubes of different diameters, which is convenient for subsequent measurement and testing.
[0020] Furthermore, a protective pad is provided, which is made of silicone and has excellent flexibility, abrasion resistance and corrosion resistance, allowing it to better fit onto the transparent conduit while reducing damage to its surface. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-7 The present invention provides the following technical solution:
[0031] Example 1: To address the problem that commercially available measuring devices often lack timely data readings, resulting in poor accuracy in measuring the distance traveled by the medium flowing in a pipeline, please refer to the attached... Figure 1 -Appendix Figure 2 and attached Figure 4 -Appendix Figure 7 The device includes a scale 1 and an infusion connector 2. The scale body 3 is located on the front and back of the scale 1. A transparent tube 15 is detachably connected to the right side of the infusion connector 2, and the end of the transparent tube 15 passes through a limiting plate 13. A thumb clip 16 is fitted on the outer wall of the left side of the transparent tube 15. The scale 1 and the groove 5 are integrated, and the scale 1 is made of transparent acrylic material.
[0032] After the transparent catheter 15 connected to the infusion connector 2 is fixedly installed inside the scale 1 through the following steps, the staff connects the infusion connector 2 to an external syringe and injects colored liquid into the external syringe. The colored liquid then enters the infusion connector 2 and flows through the transparent catheter 15. As the colored liquid flows within the transparent catheter 15, the staff can clearly observe the movement of the liquid and accurately measure the distance the liquid moves using the bidirectional scale body 3 on the scale 1. The scale 1 is made of acrylic material with high transparency, ensuring good visibility and accurate measurement, thus enabling precise measurement of the distance the colored liquid moves within the transparent catheter 15.
[0033] Example 2: Transparent conduits 15 of different diameters can be fixedly installed, as shown in the attached diagram. Figure 1 -Appendix Figure 3 and attached Figure 6The scale 1 has two symmetrically threaded holes 4 on the back of its upper and lower sides, and a groove 5 is formed inside the back of the scale body 3. It also includes two movably connected mounting sleeves 6 to the back of the scale 1. Each mounting sleeve 6 has bolts 7 threadedly connected to its upper and lower sides, and a fixing cylinder 8 is fixedly installed on both sides of the mounting sleeve 6. The fixing cylinder 8 has a sliding groove 9 inside, and a sliding plate 10 is installed inside the sliding groove 9. A spring 11 is fixedly installed on the back of the sliding plate 10, and a telescopic rod 12 is fixedly connected to the front of the spring 11. A limiting plate 13 is fixedly installed on the front of the telescopic rod 12, and a protective pad 14 is fixedly connected to the inner wall of the limiting plate 13. The groove 5 and the transparent guide tube 15 are detachably connected. The sliding plate 10 and the sliding groove 9 are slidably connected, and the sliding plate 10, spring 11, and telescopic rod 12 are tightly fitted together. The limiting plate 13 and the transparent guide tube 15 are matched, and the limiting plate 13 is designed with a semi-circular arc structure. The limiting plate 13 and the protective pad 14 are fixedly connected, and the protective pad 14 is made of silicone.
[0034] The staff aligns the mounting sleeve 6 with the corresponding position on the scale 1, inserting the bolt 7 through the mounting sleeve 6 into the corresponding threaded hole 4, thus fixing the mounting sleeve 6 onto the scale 1. The staff then measures the diameter of the transparent catheter 15 connected to the infusion connector 2 as needed, manually moving the limiting plate 13 outwards. This causes the limiting plate 13 to drive the sliding plate 10 connected to the telescopic rod 12 to slide inwards within the corresponding groove 9. During the sliding process, the sliding plate 10 compresses the spring 11, allowing the limiting plate 13 to move a suitable distance. Finally, the staff manually passes the transparent catheter 15 connected to the infusion connector 2 through the mounting sleeve. 6. Insert the ruler into the inner groove 5 of the scale 1 and release the limiting plate 13 that has been pushed through the mounting sleeve 6. Due to the rebound force, the spring 11 drives the slide plate 10 and its connected telescopic rod 12 to move outward. Thus, the telescopic rod 12 drives the protective pad 14 connected to the limiting plate 13 to adhere to the transparent guide tube 15, which is convenient for fixing and installing transparent guide tubes 15 of different diameters and facilitates subsequent measurement and testing. The protective pad 14 is made of silicone, which has excellent flexibility, wear resistance and corrosion resistance, and can better adhere to the transparent guide tube 15 while reducing damage to its surface.
