Description
Technical Field
[0001] This utility model relates to the field of intrauterine device (IUD) placement aids, specifically an IUD placement depth measuring ruler. Background Technology
[0002] An intrauterine device (IUD) is a contraceptive device placed inside the uterine cavity. Because the devices used in the early days were mostly ring-shaped, they were commonly called IUDs or simply contraceptive devices. Before IUD insertion, the depth of the uterine cavity needs to be measured, which requires the use of a uterine probe.
[0003] In existing technology, the uterine probe is a slender rod-shaped instrument made of stainless steel, with centimeter graduations marked at the end and a blunt or slightly curved head to avoid damaging tissues. However, in actual use, as the tip of the uterine probe comes into contact with the uterine cavity, the doctor needs to judge the pressure between the probe and the uterine cavity by touch. This can easily lead to excessive pressure, which can cause damage to the uterus and, in severe cases, even uterine perforation. Therefore, it is necessary to develop an intrauterine device placement depth measuring ruler to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a ruler for measuring the depth of intrauterine device placement, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an intrauterine device placement depth measuring ruler, comprising a transparent cylinder and a measuring rod, wherein a positioning mechanism is provided inside the transparent cylinder and an anti-slip mechanism is provided at the bottom of the transparent cylinder.
[0006] Preferably, the positioning mechanism includes a protruding post, which is fixedly installed on the bottom inner wall of the transparent cylinder. A spring is movably installed on the outside of the protruding post. A connecting plate is fixedly installed on the bottom of the measuring rod. A rotating block is fixedly installed on the outside of the connecting plate. A connecting cylinder is fixedly installed on the bottom of the connecting plate. A round block is movably installed on the inner wall of the connecting cylinder. A positioning groove is formed on the top of the round block. A positioning block is fixedly installed on the inner wall of the positioning groove. A square rod is slidably installed on the inner wall of the measuring rod. An abutment sleeve is fixedly installed on the top of the square rod. The abutment sleeve is slidably installed on the outside of the measuring rod to facilitate the protection of the medical personnel.
[0007] Preferably, the surface of the measuring rod is provided with scale marks to facilitate the measurement of the depth of the uterine cavity before the placement of an intrauterine device.
[0008] Preferably, the surface of the connecting cylinder is provided with external threads, and the inner wall of the transparent cylinder is provided with internal threads. The transparent cylinder is threadedly installed on the outside of the connecting cylinder, which facilitates the assembly of the transparent cylinder and the connecting cylinder.
[0009] Preferably, a groove is provided inside the square rod at the position corresponding to the positioning block, and the positioning block is slidably installed in the groove to facilitate the positioning of the round block and the square rod.
[0010] Preferably, the anti-slip mechanism includes a support plate, which is fixedly installed at the bottom of the transparent cylinder. A handle is fixedly installed at the bottom of the support plate. A storage groove is provided inside the handle, and an anti-slip pad is fixedly installed inside the storage groove. This increases the friction between the hand and the handle, prevents the hand from slipping, and facilitates stable measurement.
[0011] Compared with the prior art, this utility model provides a ruler for measuring the insertion depth of an intrauterine device (IUD), which has the following beneficial effects: 1. This intrauterine device (IUD) features a depth measuring scale. Through a positioning mechanism, during use, the square rod slides into the inner wall of the measuring rod, and as the top of the measuring rod contacts the abutment sleeve, the lower end of the square rod extends out of the connecting cylinder. This allows the square rod to slide within the positioning groove. With the cooperation of the positioning block, the round block and square rod are limited, facilitating the movement of the round block into the connecting cylinder. The transparent cylinder is threaded onto the outside of the connecting cylinder, and the spring contacts the round block. This not only facilitates quick assembly and disassembly of the measuring instrument but also simplifies subsequent sterilization. During measurement, as the abutment sleeve contacts the uterine cavity, the round block gently compresses the spring, facilitating its movement and reducing pressure to prevent excessive pressure that could damage the uterus. The easy observation of the round block's position allows the operator to promptly stop further insertion.
[0012] 2. The IUD is equipped with a depth measuring scale. The anti-slip mechanism allows the operator to easily move the measuring rod by gripping the handle. The anti-slip pad further increases friction between the hand and the handle, preventing slippage and ensuring stable measurement. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] Example 1: Please see Figure 1-4 This utility model provides a technical solution: an intrauterine device placement depth measuring ruler, including a transparent cylinder 1 and a measuring rod 2. The transparent cylinder 1 is made of medical plastic, and a positioning mechanism 3 is provided inside the transparent cylinder 1. An anti-slip mechanism 4 is provided at the bottom of the transparent cylinder 1.
[0018] Furthermore, the positioning mechanism 3 includes a protruding post 301, which is fixedly installed on the bottom inner wall of the transparent cylinder 1. A spring 302 is movably installed on the outside of the protruding post 301. A connecting plate 303 is fixedly installed on the bottom of the measuring rod 2. A rotating block 304 is fixedly installed on the outside of the connecting plate 303. The surface of the rotating block 304 is provided with anti-slip texture to increase the friction between the hand and the rotating block 304. A connecting cylinder 305 is fixedly installed on the bottom of the connecting plate 303. A round block 306 is movably installed on the inner wall of the connecting cylinder 305. The height of the round block 306 is the same as the height of the connecting cylinder 305 to facilitate subsequent observation of the movement distance of the round block 306. A positioning groove 307 is provided on the top of the round block 306. A positioning block 308 is fixedly installed on the inner wall of the positioning groove 307. A square rod 309 is slidably installed on the inner wall of the measuring rod 2. A contact sleeve 310 is fixedly installed on the top of the square rod 309. The square rod 309 is slidably installed on the outside of the measuring rod 2. By sliding the square rod 309 into the inner wall of the measuring rod 2, and with the top of the measuring rod 2 contacting the contact sleeve 310, the lower end of the square rod 309 extends out of the connecting tube 305, thus facilitating the sliding of the square rod 309 in the positioning groove 307. With the cooperation of the positioning block 308, the round block 306 and the square rod 309 are limited, the round block 306 is moved into the inside of the connecting tube 305, the transparent tube 1 is threaded onto the outside of the connecting tube 305, and the spring 302 contacts the round block 306. This not only facilitates the quick assembly and disassembly of the measuring instrument, but also facilitates subsequent disinfection. During measurement, as the contact sleeve 310 contacts the uterine cavity, the round block 306 gently squeezes the spring 302, thus facilitating the movement of the round block 306, reducing pressure, and avoiding excessive pressure that could damage the uterus.
[0019] Furthermore, the surface of the measuring rod 2 is marked with scales to facilitate the measurement of the depth of the uterine cavity before the placement of the intrauterine device.
[0020] Furthermore, the surface of the connecting cylinder 305 is provided with external threads, and the inner wall of the transparent cylinder 1 is provided with internal threads. The transparent cylinder 1 is threaded onto the outside of the connecting cylinder 305, which facilitates quick assembly and disassembly of the transparent cylinder 1 and the connecting cylinder 305.
[0021] Furthermore, a groove is provided inside the square rod 309 at the position corresponding to the positioning block 308, and the positioning block 308 is slidably installed in the groove, which facilitates the limiting operation of the round block 306 and the square rod 309.
[0022] Please see Figure 5Furthermore, in conjunction with Embodiment 1, the anti-slip mechanism 4 includes a support plate 401, which is fixedly installed at the bottom of the transparent cylinder 1. A handle 402 is fixedly installed at the bottom of the support plate 401. A storage groove 403 is provided inside the handle 402. Two sets of storage grooves 403 are provided, which are respectively located on the front and back of the handle 402. An anti-slip pad 404 is fixedly installed inside the storage groove 403 to increase the friction between the hand and the handle 402, prevent the hand from slipping, and facilitate the stable operation of the measurement work.
[0023] In actual operation, when this device is used, the square rod 309 is slid into the interior of the measuring rod 2, so that the top of the measuring rod 2 contacts the abutment sleeve 310, and the bottom of the square rod 309 extends out of the connecting cylinder 305. The square rod 309 is then slid into the positioning groove 307, where, with the cooperation of the positioning block 308, the round block 306 is positioned and limited. The round block 306 is then extended into the interior of the connecting cylinder 305, so that the top of the round block 306 contacts the connecting plate 303. The spring 302 is then placed inside the transparent cylinder 1. Then, by threading the transparent cylinder 1 onto the outside of the connecting cylinder 305, the installation of the contact sleeve 310 is completed. During measurement, by pinching the handle 402, the friction between the fingers and the handle 402 is increased with the cooperation of the anti-slip pad 404. As the measuring rod 2 moves, the contact sleeve 310 comes into contact with the uterine cavity, causing the round block 306 to slightly compress the spring 302. By observing the movement of the round block 306, the pressing force during insertion is adjusted, and the scale marks on the surface of the measuring rod 2 are observed to complete the measurement.
