Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a clamp-shaped electrode clamp for measuring human body composition. Background Art

[0002] Human body composition analysis is everyone's health "code" or health window. These analysis results can give a clearer understanding of one's own physical health. Using bioelectrical impedance measurement method, segmental body composition is accurately measured to reflect changes in extracellular water, fat, protein, inorganic salts, etc. in different segments of the body, and to determine the body's nutritional status, degree of edema, visceral fat area, etc. The measurement postures include standing, sitting and lying.

[0003] Bioimpedance contains a wealth of human pathological and physiological electrical signals, which can serve as the main basis for medical personnel to accurately judge patient symptoms and treat diseases. Construct a human body impedance model, collect and analyze human body impedance through electrodes, and obtain various component parameters of the human body. A low-frequency signal injected into the human body is generated by a signal generating circuit, and the voltage generated by the current flowing through the human body is detected by an amplitude detection circuit. The impedance information of different segments of the human body is measured by a segmented detection method, and the correlation between the data and human body composition parameters is analyzed to obtain various human body composition parameters and display the measurement results. The above content comes from "Design of Human Body Composition Tester Based on Four-Electrode Multi-Frequency Scanning by Bioimpedance Method" 2024, 47(12): 45.

[0004] In the prior art, the clamp close to human body composition measurement is the electrocardiogram electrode clamp, whose main structure includes an upper clamp, a lower clamp, a rotating shaft, a torsion spring, an electrode sheet and a wire. The upper clamp and the lower clamp can be rotatably mounted on the rotating shaft. The parts of the upper clamp and the lower clamp behind the rotating shaft are the gripping parts, and the parts of the upper clamp and the lower clamp in front of the rotating shaft are the clamping parts. The torsion spring is sleeved on the rotating shaft, one end of the torsion spring is connected to the gripping part of the upper clamp, and the other end of the torsion spring is connected to the gripping part of the lower clamp. However, the electrocardiogram electrode clamp has the following disadvantages: the clamping force of the torsion spring is not enough, which makes it easy to get loose and not fixed firmly.

[0005] Currently, when measuring the ulna and ankle bones, the electrodes need to be in full contact, and the voltage difference obtained by the electrodes is used to calculate the impedance value of the characteristic parts. If the electrodes are not in good contact or not in contact during the process, the measurement may be interrupted or the credibility of the data may be reduced.

[0006] The clamping method of the electrode clamp currently used mostly adopts the spring sheet method, and the clamping force is adjusted through three gears (weak, medium, and strong). Not only is it difficult to adjust, but even if it is adjusted to the highest gear of the elastic force, it still cannot better clamp the measuring part. This structural form cannot provide effective clamping force. When the clamping end is subjected to excessive force, it will cause the shaft part to detach and fail. Summary of the invention

DETAILED DESCRIPTION

[0044] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] like Figures 1 to 6 As shown, the present invention provides a clamp-shaped electrode clamp for measuring human body composition, which includes: an upper clamp 1, a lower clamp 2, a connecting structure, an electrode sheet 9 and a clamping mechanism 12. The upper clamp 1 and the lower clamp 2 are connected by a connecting structure, and the connecting structure includes a rotating shaft 7. The inner sides of the upper clamp 1 and the lower clamp 2 are both installed with electrode sheets 9. The clamping mechanism 12 is installed on one side of the lower clamp 2, and the clamping mechanism 12 is used to realize the switching action of locking and releasing.

[0048] The technical solution of the present invention uses the ulna and ankle as central positioning points to clamp and measure through an upper clamp 1 and a lower clamp 2 connected by a connecting structure. The electrode sheet 9 is in full contact with the ulna and ankle bone, and the impedance value of the characteristic part is calculated using the voltage difference obtained by the electrode sheet 9. An effective clamping force is provided by the clamping mechanism 12. The operation is simple, and the accuracy and repeatability of the measurement data are guaranteed, thereby improving work efficiency and reducing the workload of the operator.

[0049] The clamp electrode clamp of the present invention uses the lever principle, such as Figure 6 As shown, F1 is the force we apply, and F2 is the force on the skin. Point A in the figure is the fulcrum. From the principle of lever, we know that: F1xD1=F2xD2, where the power arm D1 is much larger than the resistance arm D2, so F1 is much smaller than F2. The difference from the iron pliers is that the present invention is a laborious lever. Although it is laborious to use, it can effectively clamp and reduce the moving distance of the hand.

[0050] The upper clamp 1 includes an upper clamping portion 3 and an upper gripping portion 5, which are respectively located on both sides of the rotating shaft 7. The lower clamp 2 includes a lower clamping portion 4 and a lower gripping portion 6, which are respectively located on both sides of the rotating shaft 7. In the present invention, the clamp shapes of the upper clamp 1 and the lower clamp 2 can be well buckled, so that the clamping mechanism 12 can better cooperate to achieve a good clamping and buckling effect.

[0051] The connection structure also includes a torsion spring 8, which is installed on the lower gripping part 6. A wire 10 is connected to the electrode sheet 9. A shielding cover 11 is installed on both the upper clamp 1 and the lower clamp 2. The clamping mechanism 12 can realize the switching action of locking and loosening, which is suitable for measuring different people.

[0052] The clamping mechanism 12 includes a push rod 1207 and a push rod sleeve 1201 . The push rod sleeve 1201 is sleeved on the push rod 1207 , and the push rod 1207 is installed on the lower gripping portion 6 .

[0053] The clamping mechanism 12 also includes a button lower shaft 12027, a button upper shaft 12037, a compression spring 1204, a button 1205 and a button pull rod 1206. The button pull rod 1206 is connected to the push rod sleeve 1201. The compression spring 1204 is installed below the button 1205. The button pull rod 1206 is installed at one end of the button 1205. The button upper shaft 12037 is installed on the button pull rod 1206. The button lower shaft 12027 is connected to the end of the button 1205.

[0054] The clamping mechanism 12 further includes a push rod shaft 1208 , which is mounted on the end of the push rod 1207 .

[0055] The clamping mechanism 12 further includes a fixing pin 1209, a short arc pawl 1210, a short arc ratchet 1211 and a stop pin 1212. The fixing pin 1209 is mounted on the short arc pawl 1210. The push rod rotating shaft 1208 is used to connect the push rod 1207 with the short arc pawl 1210. The short arc pawl 1210 is connected with the short arc ratchet 1211. The stop pin 1212 is mounted on the end of the short arc ratchet 1211. Specifically, the clamping mechanism 12 is not limited to the ratchet 1211 structure, and can also be a gear, a cam, or an eccentric wheel mechanism.

[0056] The present invention provides a clamp-shaped electrode clamp for measuring human body composition. It only needs to press down the upper gripping part 5 and the lower gripping part 6 to achieve compression, and press the button 1205 to achieve the release and open the device. The clamp-shaped electrode clamp for measuring human body composition is easy to operate, ensures the accuracy and repeatability of the measurement data, thereby improving work efficiency and reducing the workload of the operator.

[0057] Working process:

[0058] The present invention presses button 1205 to open the clamping parts of the upper clamp 1 and the lower clamp 2 of the clamp electrode to the maximum angle, and positions them at the center positioning points of the ulna and the ankle. Press the upper grasping part 5 and the lower grasping part 6, and gradually apply force. At this time, the short arc pawl 1210 and the short arc ratchet wheel 1211 are engaged in sequence until the upper clamp 1 and the lower clamp 2 are clamped. After ensuring that the electrode sheet 9 is in full contact with the skin, release the fingers and repeat the operation of other clamps until 4 groups are completed (clamped at the two ulna centers and the two ankle centers of the user respectively), and then proceed to the next test operation.

[0059] When the test is completed, the button 1205 is pressed, the short arc pawl 1210 pops up, and under the action of the torsion spring 8, the upper clamp 1 and the lower clamp 2 open, and the four sets of clamp-shaped electrode clamps can be removed and placed in the specified position.

[0060] The present invention provides a clamp-shaped electrode clamp for measuring human body composition, in order to be able to change and solve the accuracy, reliability and stability of existing human body composition measurements. Improve the operator's work efficiency and avoid distortion of measurement data. The clamp-shaped electrode clamp for measuring human body composition provided by the present invention uses the ulna and ankle as the central positioning points for clamping and measurement. The measurement method has better repeatability in clinical research in the medical industry, avoids movement after positioning, and makes the measurement more accurate. It can be used in lying, standing and sitting positions, and multiple test conditions can be met as much as possible to ensure the clamping force.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention 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 replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
