Description

TECHNICAL FIELD

[0002] The tissue mechanics detection devices on the market generally have a movement mechanism function, and are complex in structure, large in overall volume, high in cost, inconvenient to use in small-space rehabilitation hospitals, inconvenient to carry out flexible clinical diagnosis, and not portable.

[0003] When measuring the product, the device product is usually used to press the skin and muscles of each part of the human body, and then the tissue hardness of the skin layer and muscle layer of the human body is calculated through the relationship between the tissue hardness and displacement. Unlike the measurement of physical materials such as rubber and steel, it is easy to obtain a cut regular shape to ensure measurement accuracy. However, each part of the human body is basically a three-dimensional curved surface, not a regular plane, and it is difficult to ensure the consistency of the measurement direction. At the same time, the human body tissue is in vivo, and cannot be taken out and used and checked in vitro.

[0004] The existing technology usually uses human eyes to observe and subjectively judge whether the contact head is in full contact with the measurement part, so as to determine whether the measurement process is reasonable. There are human subjective judgment factors, and it is difficult for the same measurement operator to perform consistent and repetitive pressing measurement operations on the same measurement part. Even if the same operator collects data in the same area, the collected data still has great differences. Further, for different measurement operators and human body tissue parts with more complex curved surfaces, it is difficult to observe through the naked eye, resulting in measurement operation errors.

[0005] Based on the above many human factors, in the entire measurement process, it is difficult to control the three uncertain factors of pressing in which direction, pressing to what depth, and when to collect the measurement results. It is difficult to ensure the consistency and repeatability of the measurement results. CONTENT OF THE UTILITY MODEL

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0038] In the description of the present application, it should be noted that the positions or location relationships indicated by the terms “inner”, “outer” and the like are based on the positions or location relationships shown in the drawings, or the positions or location relationships of the products of the present application when they are usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated devices or elements must have a particular position, be constructed and operated in a particular position, and therefore cannot be understood as limiting the present application. In addition, the terms “first”, “second” and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms “set”, “connected” should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0040] The tissue mechanics detection device in the application mainly detects the elasticity of skin muscle tissue through a compact detection device main body, specifically, after all the capacitive sensing components included in the detection device main body are all in contact with the skin muscle and all have capacitive changes, the sensing components are triggered to collect detection data, thereby avoiding the influence of human factors in the pressing detection process, achieving consistency and repeatability in different pressing detection processes, and ensuring the accuracy of the detection structure.

[0041] In the pressing detection process, the tissue mechanics detection device in the application is mainly based on the mechanism of capacitive sensing. When the detection device contacts the human body, the dielectric constant of the capacitive sensing components at the head end changes, causing a change in the capacitance value. Only when all the capacitive sensing components have capacitive changes close to the skin, the sensing components are triggered to collect detection data.

[0042] Based on the above mechanism, referring to Figs. 1-3 The tissue mechanics detection device in the application includes a detection device body 1, a detection probe 2, and a probe shell 3. The detection device body 1 is mainly used to integrate and install the necessary functional structures of the tissue mechanics detection device, and the detection probe 2 is mainly used for sensing and triggering data detection. The probe shell 3 is used for contact with the skin muscle tissue on one hand, and for mounting the capacitive sensing components on the other hand. Through the contact of the probe shell 3 with the skin muscle, the capacitance of all capacitive sensing components changes under the condition that the capacitive sensing components are electrically connected with the sensing components, indicating that the contact is fully in place, triggering the sensing components, and then collecting data.

[0043] The detection probe 2 is arranged at the head end of the detection device body 1, which can facilitate the triggering of data detection. The probe shell 3 is detachably connected to the detection device body 1, which can realize the one-time use of the probe shell 3. By arranging the probe shell 3 and the detection probe 2 in a relative position, the capacitive sensing components and the sensing components can be electrically connected in a separated manner.

[0044] The probe shell 3 is provided with a plurality of capacitive sensing metal sheets 4 around the circumference, which constitute the capacitive sensing components of the tissue mechanics detection device. The detection probe 2 is provided with a sensing circuit chip 5, which constitutes the sensing components of the tissue mechanics detection device. The detachable connection of the probe shell 3 and the detection device body 1 can make the plurality of capacitive sensing metal sheets 4 be detachably connected to the sensing circuit chip 5, thereby realizing the electrically connected in a separated manner of the capacitive sensing components and the sensing components, which is beneficial to triggering the sensing components to collect detection data after the capacitance of all the capacitive sensing metal sheets 4 of the capacitive sensing components changes.

[0045] In order to ensure that the probe shell 3 is pressed to cover the detection skin muscle tissue during the detection process, a plurality of capacitive sensing metal sheets 4 are uniformly distributed on the probe shell 3. The probe shell 3 includes a detection plate 31 for adhering to the skin. The capacitive sensing metal sheets 4 are fixedly bonded to the inner side wall of the detection plate 31.

[0046] During the adhering and pressing detection process, the detection plate 31 with a flat wall structure is adhered and pressed on the skin muscle part. The capacitive sensing metal sheet 4 fixedly bonded to the inner side wall of the detection plate 31 is close to the skin muscle tissue, thereby changing the dielectric constant and changing the capacitance value of the capacitive sensing metal sheet 4. Then, the capacitive sensing metal sheet 4 and the sensing circuit chip 5 are electrically connected, and the capacitance value change signal is transmitted to the sensing circuit chip 5.

[0047] At the same time, in order to enable the capacitive sensing metal sheet 4 to be effectively and reliably connected with the sensing circuit chip 5, a plurality of touch springs 51 are arranged on the sensing circuit chip 5. When the probe shell 3 is connected to the detection device body 1, the capacitive sensing metal sheet 4 is tightly connected to the front side of the sensing circuit chip 5 through the touch spring 51, thereby realizing the conduction of the electrical connection path through the touch spring 51. At the same time, it can be ensured that after the probe shell 3 is assembled on the detection device body 1, the capacitive sensing metal sheet 4 can be tightly pressed and matched with the sensing circuit chip 5 fixed on the detection probe 2.

[0048] In order to ensure the effective conduction of the electrical connection path between the capacitive sensing metal sheet 4 and the sensing circuit chip 5, the touch spring 51 includes a plurality of touch springs 51, and the plurality of touch springs 51 correspond to the capacitive sensing metal sheet 4 one by one. Preferably, the probe shell 3 is detachably clamped and assembled on the head end of the detection device body 1 in a rotating form. When the probe shell 3 is clamped in place, the capacitive sensing metal sheet 4 can be opposite to the position of the touch spring 51.

[0049] Specifically, the detection device body 1 includes a mounting shell 11 located at the head end. The outer side wall of the mounting shell 11 is provided with a connecting clamping groove 12. The probe shell 3 is in the form of an end cover structure, which includes a connecting ring plate 32 integrally connected with the detection plate 31. The inner side wall of the connecting ring plate 32 is provided with a connecting clamping block 33. The probe shell 3 is detachably connected to the detection device body 1 through the rotating clamping of the connecting clamping block 33 and the connecting clamping groove 12.

[0050] Through this kind of setting mode, the detachable connection of the probe shell 3 on the detection device body 1 is facilitated, which is beneficial to the one-time throwing application of the probe shell 3 during the detection process, and at the same time, the electrical circuit conduction between the capacitive sensing metal sheet 4, the touch spring 51 and the sensing circuit chip 5 is maintained after clamping and assembling.

[0051] The detection probe 2 is fixedly installed on the radial inner side of the mounting shell 11, and a positioning column 6 for positioning and installing the detection probe 2 is arranged on the radial inner side of the mounting shell 11.

[0052] The circumferential distribution position of the capacitive sensing metal sheet 4 on the probe shell 3 and the distribution position of the connecting clamping block 33 on the probe shell 3 are relatively fixed, and the arrangement position of the touch spring 51 on the detection probe 2 and the arrangement position of the connecting clamping groove 12 on the mounting shell 11 are also relatively fixed, and the detection probe 2 is connected to the mounting shell 11 at the head end of the detection device body 1 through the positioning column 6, so that after the probe shell 3 is rotationally clamped in place, the positions of the capacitive sensing metal sheet 4 and the touch spring 51 are relatively fixed, and the accurate and reliable conduction relationship of the circuit conduction is further ensured.

[0053] In the utility model, the head end of the detection device body 1 is provided with a contact head 7 for being pressed on the skin, the contact head 7 penetrates through the detection probe 2 and extends outward from the probe shell 3. In the normal use process, the detection of the elasticity of the skin muscle tissue is carried out through the pressing operation of the contact head 7 on the skin muscle tissue part. The detection process of the tissue mechanics detection device is not the focus of the present application, and the specific technical scheme can be referred to the prior application with the application number CN2024212777829, which will not be repeated here.

[0054] The sealing ring 8 is arranged at the penetrating part of the contact head 7 and the detection probe 2, protects the moisture-proof drainage and weather resistance of the sensing circuit chip 5, the sealing ring 8 is clamped on the outside of the contact head 7 and is accommodated and installed in the ring groove 21 at the center of the detection probe 2, so that the sealing ring 8 can reliably seal and protect the sensing circuit chip 5 under the condition of being effectively installed.

[0055] Based on the above-mentioned one-time throwing use state of the probe shell 3, the material of the probe shell 3 in the utility model includes a medical grade engineering plastic, and the capacitive sensing metal sheet 4 includes a stainless steel sheet, so that the processing and manufacturing cost can be reduced under the premise of meeting the use requirements.

[0056] Meanwhile, in order to facilitate processing, the probe shell 3 includes an end cover structure connected to the detection device body 1, and the detection plate 31 and the connecting ring plate 32 are integrally formed, which is beneficial to mass production.

[0057] The tissue mechanics detection device in the utility model can exclude artificial subjective judgment factors in the pressing detection process, more objectively carries out data acquisition, and at the same time, the three-dimensional surface interference of different parts of human tissue is excluded, so that the consistency and repeatability of the results of different detection processes at the same part are improved.

[0058] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0059] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
