Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a positioning device for a bone density analyzer arm. Background Technology

[0002] A bone mineral density analyzer is a device that assesses the bone density of the radius and ulna in the forearm by measuring the attenuation of X-rays. Dual-energy X-ray absorptiometry (DXA) is currently the standard technique for measuring bone mineral density.

[0003] During the measurement process, the arm needs to be exposed and placed on the instrument's beam limiting device. The arm must be properly positioned before the test can be performed. Although the current beam limiting device is marked with position scales, because the beam limiting device is located inside the instrument, the scales cannot be directly observed from the outside. Furthermore, the arm cannot be quickly positioned on the beam limiting device and requires constant adjustments in all directions, wasting time and resulting in a poor physical examination experience. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this invention is to provide a bone density analyzer arm positioning device that can quickly locate the position of the arm, thereby improving detection efficiency and the user's experience.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A bone density analyzer arm positioning device is provided, including a detection chamber, a support mechanism in the detection chamber, and a groove on the upper surface of the support mechanism, in which the arm can be placed;

[0007] The groove is also provided with a positioning protrusion.

[0008] Furthermore, the support mechanism is slidably connected to the testing chamber, allowing the support mechanism to be removed from the testing chamber.

[0009] Furthermore, the support mechanism is equipped with a fixing mechanism.

[0010] Furthermore, the fixing mechanism includes a pressure block, and a pressure groove is formed on the lower end surface of the pressure block, which can fix the upper end of the arm.

[0011] Furthermore, the pressure block is connected to the support mechanism via a telescopic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The bone density detector arm positioning device of this utility model can quickly position the arm of the subject through the groove and positioning protrusion, avoiding the problem of wasting time by adjusting the arm back and forth, thus improving the detection efficiency and the experience of the subject.

[0014] 2. The arm positioning device of the bone density detector of this utility model has a support mechanism that can be removed from the testing chamber, so that the person being tested can clearly see the position where the arm needs to be placed, making the arm more accurately positioned.

[0015] 3. The bone density detector arm positioning device of this utility model can fix the arm from above, thereby reducing the probability of arm displacement and further improving the positioning accuracy. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] like Figure 1-2As shown, this embodiment provides a bone density detector arm positioning device, including a detection chamber 1. The detection chamber 1 is provided with a support mechanism 2 for supporting the arm and a detection mechanism for detecting bone density. During detection, the arm is extended into the detection chamber 1, the arm is supported on the support mechanism 2, and the detection mechanism detects the bone density.

[0025] In this embodiment, a groove 3 is provided on the upper surface of the support mechanism 2, and the arm can be placed in the groove 3 for positioning the arm in the front-back direction. The groove 3 is also provided with a positioning protrusion 4, which allows the subject to more intuitively feel the position where the arm needs to be extended, so as to position the arm in the left-right direction.

[0026] In addition, to facilitate the observer's observation of the arm's placement, the support mechanism 2 in this embodiment can be removed from the detection chamber 1. Specifically, the support mechanism 2 is slidably connected to the detection chamber 1, and a slide rail mechanism can be installed below the support mechanism 2 to connect the support mechanism 2 and the detection chamber 1.

[0027] During the test, the support mechanism 2 is first removed from the testing chamber 1. Medical staff then instruct the patient on the approximate position A where the arm should be placed. The patient places their arm in the groove 3 and moves it to the corresponding position on the positioning protrusion 4. This allows for quick and easy positioning of the arm in the forward / backward and left / right directions, improving testing efficiency and enhancing the patient's experience. Afterward, the arm moves the support mechanism 2 into the testing chamber 1 for the test to proceed.

[0028] Example 2:

[0029] To further secure the arm, this embodiment adds a fixing mechanism based on Embodiment 1. Specifically, the fixing mechanism is located above the support structure and includes a pressure block 5. A pressure groove 6 is formed on the lower end surface of the pressure block 5, and the pressure groove 6 can fix the upper end of the arm.

[0030] To facilitate adjustment of the height of the pressure groove 6, the pressure block 5 is connected to the support mechanism 2 via a telescopic rod 7. Adjusting the extension length of the telescopic rod 7 allows for adjustment of the height of the pressure block 5, facilitating the insertion and removal of the arm and enabling the height of the pressure groove 6 to accommodate different subjects. In this embodiment, to prevent the fixing mechanism from interfering with the testing, it can be installed on the edge of the support mechanism 2, ensuring effective fixation of the arm without affecting the testing process.

[0031] Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-mentioned technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-mentioned technical features or their equivalent features without departing from the inventive concept. For example, technical solutions formed by substituting the above-mentioned features with technical features disclosed in this application (but not limited to) that have similar functions.
