Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an external pelvic measuring instrument. Background Art
[0002] The pelvic measurement device is used to measure the size and shape of the pelvis. The relevant parameters of the pelvis can help doctors evaluate the delivery method of pregnant women and develop appropriate production plans. Pelvic measurement can be divided into two categories: external pelvic measurement and internal pelvic measurement. When measuring internally, the doctor needs to insert the relevant measuring components into the pregnant woman's vagina so that the measuring components are tightly against the corresponding part of the pelvis, so as to measure the internal dimensions of the pelvis more accurately. External pelvic measurement is a method of roughly evaluating the size and shape of the pelvis by measuring the external dimensions of the pelvis. The external pelvic measurement instrument does not require invasive measurement and is highly safe. Pregnant women can use it at home.
[0003] The external pelvic measurement indicators include the iliac crest diameter, the iliac spine diameter, the sacral pubic diameter, the ischial tuberosity diameter, the hip angle, and the degree of pelvic tilt. Most of the existing external pelvic measuring instruments measure the external dimensions of the pelvis by setting scale lines or angle lines on their surfaces and aligning multiple parts of the pelvis to be measured with the scale lines or angle lines in turn. When in use, the pelvic measuring device is held in hand and the posture of the human body is adjusted so that the pelvic measuring device fits the corresponding parts to be measured in turn, thereby obtaining multiple external dimension parameters of the pelvis.
[0004] However, this type of pelvic measurement device is not easy to fix. During the entire measurement process, the pregnant woman needs to continuously press the pelvic measurement device to prevent the pelvic measurement device from shifting from the measured part of the human pelvis, which brings great inconvenience to the pregnant woman; moreover, if the pelvic measurement device shifts, the pregnant woman may have a large error in reading, making it difficult to ensure the measurement accuracy of the pelvic measurement device.

[0026] Combine the following Figure 1 , through specific embodiments and application scenarios, a pelvic external measuring instrument provided by an embodiment of the utility model is described in detail.
[0027] like Figure 1 As shown, the utility model provides a pelvic external measuring instrument, comprising: a body 1 and a buckle 2. The surface of the body 1 is provided with scale lines 11, and the scale lines 11 extend along the axial direction of the body 1. The buckle 2 is arranged at one end of the body 1 and is arranged at an angle with the body 1. The buckle 2 is used to be fixed in the area where the human body's hip bone is located, so that the body 1 is closely fitted with the area where the pelvis is located.
[0028] It is understandable that the human pelvis has multiple parts, such as the iliac crest and iliac spine. The external pelvic measuring instrument is used to measure multiple geometric parameters of the human pelvis. The external geometric parameters of the pelvis include the iliac crest diameter, the iliac spine diameter, the sacral pubic diameter, the ischial tuberosity diameter and the hip angle. In order to help doctors evaluate the delivery method of pregnant women, users need to measure all the above geometric data through the external pelvic measuring instrument.
[0029] Specifically, the body 1 is in the shape of a long strip. Figure 1As shown, the surface of the main body 1 is provided with scale lines 11. The scale lines 11 are extended along the axial direction of the subject. The main body 1 is similar to a ruler. When in use, the main body 1 is pressed tightly against the part to be measured, and the starting point of the scale lines 11 is pressed against one of the boundary positions of the current part to be measured; then, the scale corresponding to another boundary position of the current part to be measured is read by the naked eye to obtain the size of the current part to be measured; then, by adjusting the lying posture of the human body, or moving the position of the main body 1 relative to the human body, so that the starting point of the scale lines 11 is aligned with a boundary position of the next part to be measured of the pelvis, and so on, so as to measure the geometric parameters of multiple different parts of the pelvis in turn.
[0030] In order to improve the stability of the main body 1 during measurement and ensure that the main body 1 is not easily displaced, Figure 1 As shown, the pelvic external measuring instrument also includes a buckle 2. The buckle 2 is arranged at one end of the body 1, and forms a certain angle with the body 1, and the two are arranged to form an arc area to adapt to the shape of the human hip bone and pelvis. Optionally, the angle between the buckle 2 and the body 1 can be 50° or 60°, etc. The buckle 2 is used to be fixed in the area where the human hip bone is located, and the body 1 can be closely attached to the part of the human pelvis to be measured.
[0031] The utility model provides a pelvic external measuring instrument. The surface of a main body 1 is provided with scale lines 11. A buckle 2 is arranged at one end of the main body 1 and is arranged at an angle with the main body 1 to adapt to the shapes of the hip bone and pelvis of the human body. The buckle 2 is used to be fixed in the area where the hip bone of the human body is located, and the main body 1 can be tightly fitted with the area where the pelvis is located. The user does not need to press the main body 1 continuously, which improves the user's use experience. At the same time, it ensures that the main body 1 will not shift during the measurement process, which is convenient for the user to read the scale on the main body 1, and ensures the accuracy of the measurement of the pelvic external measuring instrument.
[0032] In some embodiments, the buckle 2 is rotatably disposed on the body 1. As the buckle 2 rotates, the angle between the body 1 and the buckle 2 changes.
[0033] It is understandable that one end of the buckle 2 is rotatably provided on the main body 1, that is, the angle between the buckle 2 and the main body 1 can be changed, and the arc area enclosed by the buckle 2 and the main body 1 can be adaptively changed with the size of the user's hip bone and pelvis, so that the external pelvic measuring instrument can adapt to people of different physiques and has good versatility.
[0034] In some embodiments, Figure 1As shown, the clip 2 is hingedly connected to the body 1 through a pin 12. One end of the clip 2 is provided at the first connection hole. The body 1 is provided with a second connection hole at one end close to the clip 2. The pin 12 is sequentially passed through the first connection hole and the second connection hole to connect the clip 2 and the body 1 together. The size of the first connection hole is slightly larger than the outer diameter of the pin 12, so that the clip 2 can rotate relative to the body 1, thereby changing the angle between the clip 2 and the body 1.
[0035] In some embodiments, Figure 1 As shown, the buckle 2 is arc-shaped. The center angle of the buckle 2 faces the body 1. The side of the body 1 close to the buckle 2 is curved, which is used to fit the shape of the human pelvis.
[0036] It is understandable that the human body's hip bone is arc-shaped. In order to enable the buckle 2 to better press the body 1 into the area where the pelvis is located, such as Figure 1 As shown, the buckle 2 is arranged in an arc shape, and the arc center of the buckle 2 faces the main body 1 to fit the shape of the human hip bone, thereby improving the fit between the buckle 2 and the human hip bone, thereby ensuring the stabilizing effect of the buckle 2 on the main body 1.
[0037] Furthermore, if Figure 1 As shown, one side of the body 1 close to the buckle 2 is curved to adapt to the curve of the human pelvis. The body 1 can fit more closely to the part of the pelvis to be measured, thereby improving the accuracy of the external pelvic measuring instrument.
[0038] In some embodiments, Figure 1 As shown, the buckle 2 is provided with an angle line 21 , and the angle line 21 extends along the circumference of the buckle 2 .
[0039] It is understandable that because the hip bone is adjacent to the pelvis, doctors will use the geometric parameters of the hip bone as one of the reference indicators when determining the delivery method of pregnant women. Obtaining the angle of the hip bone is of great significance for accurately formulating the delivery method and production plan.
[0040] like Figure 1 As shown, the surface of the buckle 2 is provided with an angle line 21. The angle line 21 is provided to extend along the circumference of the buckle 2. When the buckle 2 is fixed to the area where the hip bone of the human body is located, the angle line 21 of the buckle 2 facilitates the user to quickly read the angle of the hip bone.
[0041] In some embodiments, the body 1 and the buckle 2 are both flexible silicone parts. The flexible silicone parts have good deformation performance and can adapt to changes in the lying posture of the human body; at the same time, compared with the steel body 1 and buckle 2, the flexible silicone parts can improve the user's comfort experience.
[0042] Of course, the body 1 and the buckle 2 may also be made of flexible materials such as rubber or latex.
[0043] In other embodiments, Figure 1 As shown, the pelvic external measuring instrument provided by the utility model also includes a digital display component 3. The digital display component 3 is movably arranged on the body 1, and a capacitive grid displacement sensor is arranged between the body 1 and the digital display component 3. The starting point of the scale line 11 is located at the connection point between the body 1 and the buckle 2, and the capacitive grid displacement sensor is used to measure the length information between the digital display component 3 and the connection point.
[0044] It is understandable that the digital display component 3 is used to display the size of each part to be measured on the pelvis. Specifically, the main grid of the capacitive grating displacement sensor is arranged on the main body 1 and extends along the axis of the main body 1. Among them, the starting position of the main grid is located at the starting point on the main body scale line 11. The secondary grid of the capacitive grating displacement sensor is arranged in the digital display component 3. The digital display component 3 moves in the extension direction of the main body 1, so that the capacitive grating displacement sensor can detect the length information of the digital display component 3 relative to the starting point of the scale line 11.
[0045] Specifically, Figure 1 As shown, the digital display assembly 3 includes a positioning rod, an electronic screen 31 and a moving disk 32. The moving disk 32 moves along the axial direction of the body 1 through a guide structure. The positioning rod is arranged on the moving disk 32 to point to the area where the human pelvis is located. The electronic screen 31 is installed on the surface of the moving disk 32 and is electrically connected to the capacitive displacement sensor to display length information.
[0046] It is understandable that the electronic screen 31 is mounted on the surface of the movable disk 32. Through the guide structure, the movable disk 32 can move along the axial direction of the body 1. The positioning rod is provided on the movable disk 32. The positioning rod is used to point to another boundary position of the part to be measured, so that the user can observe whether the movable disk 32 is accurately located at the boundary position to ensure the accuracy of the measurement.
[0047] A processor is installed in the digital display assembly 3. The capacitive displacement sensor is electrically connected to the processor, and the processor is electrically connected to the electronic screen 31, so that the length information detected by the capacitive displacement sensor can be fed back to the electronic screen 31 for display.
[0048] When in use, first fix the buckle 2 to the area where the hip bone is located. At this time, the starting point on the scale line 11 is exactly located at one of the boundary positions of the pelvic part to be measured; then move the movable disk 32 to the starting position of the scale line 11. When "0" is displayed on the electronic screen 31, it indicates that the digital display component 3 has returned to its position; then, push the movable disk 32 by hand until the positioning rod points to another boundary position of the part to be measured. At this time, the number displayed on the electronic screen 31 is the length of the current part to be measured.
[0049] In some embodiments, the guide structure includes a slider, which is fixed to the movable plate 32 . The body 1 is provided with a slide groove 13 , which extends along the axial direction of the body 1 , and the slider is movably provided in the slide groove 13 .
[0050] It is understandable that the slider is convexly disposed on a side of the moving plate 32 close to the body 1. The axial direction of the slide groove 13 is arranged parallel to the axial direction of the body 1. Figure 1 As shown, the scale line 11 is located at the outer edge of the body 1, and the slide groove 13 is located in the middle area of the body 1 to avoid the scale line 11. The size of the slider is adapted to the slide groove 13. The slider is movably arranged in the slide groove 13, so that the movable disk 32 can move along the axial direction of the body 1.
[0051] In some embodiments, the positioning rod includes a first rod body and a second rod body, one end of the first rod body is fixed to the moving plate 32, and the second rod body is slidably inserted into the other end of the first rod body.
[0052] It is understandable that the positioning rod is retractable. The first rod body and the second rod body are both hollow rods. One end of the first rod body is fixed to the side of the moving plate 32 close to the human body. The cross-sectional size of the first rod body is slightly larger than the cross-sectional size of the second rod body. The second rod body is inserted at the other end of the second rod body and can slide along the inner wall of the first rod body.
[0053] When the moving plate 32 moves to the boundary position, the second rod body can be extended from the first rod body so that the end of the positioning rod points to the human body. When the measurement is completed, the second rod body can be inserted into the first rod body for easy storage.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
