Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an electrode belt and electrical impedance imaging equipment. Background Art

[0002] Electrical impedance tomography (EIT) is a technology that uses the electrical impedance characteristics of the biological body to perform imaging, and is used to reconstruct the conductivity of tissues or organs or the changes in conductivity over time. This technology has the advantages of no radiation, non-invasiveness, low cost, high resolution, portable equipment, and can be used for real-time bedside imaging, with broad application prospects. In order to perform biomedical electrical impedance imaging, a certain number of electrodes (such as 16) need to be arranged around the body of the object to be tested, and then the data for image reconstruction is obtained by alternately stimulating two adjacent electrodes and measuring the potential difference between the remaining electrodes. Fixing the electrodes to the body of the object to be tested in a simple way and making good contact between the electrodes and the body of the object to be tested is the basis for stable data acquisition of electrical impedance imaging.

[0003] At present, there are two methods for fixing electrodes on the body of the object to be tested. One is to manually fix 16 electrodes one by one around the body of the object to be tested. This fixing method has the disadvantages of cumbersome electrode pasting process, inability to ensure uniform distribution of electrodes, and complex electrode feeding lines. The other is to use a belt to first fix the 16 electrodes on the belt, and then fix the belt around the body of the object to be tested. This fixing method has the following disadvantages: the belt has poor elasticity, it is difficult for the electrodes to always maintain good contact with the skin, the electrode feeding line is complex and inconvenient to operate, the belt length is different for different body circumferences of the object to be tested, and after the belt length is adjusted, it is impossible to ensure uniform distribution of electrodes.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The present invention provides an electrode belt. Figure 1 As shown, the electrode belt includes: a waist belt body 110, a plurality of electrode sheets 120, a flexible electrode slide rail 130, a first indication module 140 and a second indication module 150;

[0034] A flexible electrode slide rail 130 is provided in the long dimension direction of the waistband body 110, and a plurality of electrode sheets 120 are provided on the flexible electrode slide rail 130, and the electrode sheets 120 can slide along the flexible electrode slide rail 130;

[0035] A connecting piece 160 is disposed at one end of the waistband body 110, and a plurality of matching pieces 170 are disposed at the other end of the waistband body 110. The plurality of matching pieces 170 are sequentially disposed at preset intervals along the long dimension direction of the waistband body 110;

[0036] The first indication module 140 is disposed on one side of the flexible electrode slide rail 130 ; the second indication module 150 is disposed at a position adjacent to the plurality of matching components 170 .

[0037] exist Figure 1In the electrode belt shown, the belt body 110 may be elastic or inelastic. When the belt body 110 is elastic, its material may be at least one of elastic fabric, elastic silicone, and elastic belt. The electrode sheet 120 is connected to the electrical impedance imaging terminal through an electrode line. A flexible electrode rail 130 is provided in the long dimension direction of the belt body 110, and a slide groove is provided on the flexible electrode rail 130. A fixing piece is provided in the slide groove. A connector 160 is fixedly provided on the non-skin contact surface of the electrode sheet 120. The connector 160 can be provided in the slide groove so that the electrode sheet 120 slides on the flexible electrode rail 130. The fixing piece in the slide groove can fix the electrode sheet 120 to any position on the flexible electrode rail 130. Specifically, the number of the flexible electrode slide rail 130 can be one, and one flexible electrode slide rail 130 is arranged along the long dimension direction of the waistband body 110. All electrode sheets 120 of the electrode belt are arranged on the flexible electrode slide rail 130, and all electrode sheets 120 can slide along this flexible electrode slide rail 130; the number of the flexible electrode slide rail 130 can be multiple, and the multiple flexible electrode slide rails 130 are arranged in sequence along the long dimension direction of the waistband body 110, each flexible electrode slide rail 130 corresponds to an electrode sheet 120, and each electrode sheet 120 can slide along the corresponding flexible electrode slide rail 130. In addition, an additional flexible electrode rail 130 can be set in parallel below the original flexible electrode rail 130, so that the electrode sheet 120 can be correspondingly fixed on the parallel rail. That is, when there is one flexible electrode rail 130, an additional flexible electrode rail 130 is set in parallel below this flexible electrode rail 130; when there are multiple flexible electrode rails 130, an additional flexible electrode rail 130 is set in parallel below each flexible electrode rail 130. In this way, the electrode sheet 120 can slide along the two parallel flexible electrode rails 130 to better fix the position of the electrode sheet 120, avoid the rotation or dislocation of the electrode sheet 120, and provide a guarantee for good contact between the electrode and the body of the object to be tested. In addition, because the flexible electrode rail is set with flexible materials, the discomfort caused to the object to be tested by the long-term use of the electrode belt can be reduced. The first indication module 140 is arranged on one side of the flexible electrode slide rail 130; the first indication module 140 is used to display the fixed positions of each electrode sheet 120 corresponding to the belt loop size grade, and the second indication module 150 is used to display the belt loop size grade formed after the belt connector 160 and the matching piece 170 are connected. The fixed positions of each electrode sheet 120 are different for different belt loop size grades.

[0038] In addition, the connecting piece 160 of the belt body 110 is used to connect with the matching piece 170 so that the belt is fixed around the body of the subject to be tested. A plurality of matching pieces 170 are arranged in sequence at preset intervals along the long dimension direction of the belt body 110. Different matching pieces 170 correspond to different belt loop size levels. By setting a plurality of matching pieces 170, the belt loops formed after the connecting piece 160 is connected with different matching pieces 170 are different in size, so that the electrode belt is suitable for subjects to be tested with different body circumferences. Specifically, the connecting piece 160 is a buckle or a button; when the connecting piece 160 is a buckle, the corresponding matching piece 170 is a hook; when the connecting piece 160 is a button, the corresponding matching piece 170 is a buttonhole.

[0039] In this way, by providing a plurality of matching pieces that can be connected to the connecting piece, the sizes of the belt loops formed after the connecting piece is connected to different matching pieces are different, so that the electrode belt can be adapted to the subjects of different body circumferences, and a good contact between the electrode sheet and the skin of the subject to be tested is guaranteed. The plurality of electrode sheets can be slid to the equal distribution positions corresponding to the sizes of the belt loops displayed by the first indication module, respectively, and fixed to achieve uniform distribution of the electrode sheets. After the electrode sheets are fixed according to the equal distribution positions corresponding to the sizes of the belt loops, the electrode belt can be fixed around the subject to be tested by connecting the connecting piece to the corresponding matching piece, which is simple and convenient to use.

[0040] In specific implementation, in the electrode belt provided in the embodiment of the present application, the first indication module 140 and the second indication module 150 have various structures to realize their functions, for example Figure 2 As shown, the first indicator module 140 includes multiple groups of first indicator members, each group of first indicator members is evenly arranged at a corresponding preset distance along the long dimension direction of the waistband body; the preset distances corresponding to the first indicator members of each group of the multiple groups of first indicator members are different;

[0041] The second indicating module 150 includes a plurality of second indicating members, each of which corresponds to a group of first indicating members, and each of which is disposed at a position adjacent to a group of matching members.

[0042] exist Figure 2In the electrode belt shown, the first indicator module 140 includes multiple groups of first indicators, each group of first indicators can be set in a row, and multiple groups of indicators can be set in different rows. The second indicator can be set around the corresponding matching piece 170. Since in actual use, the various electrode sheets need to be evenly distributed around the object to be measured, the setting position of each group of first indicators in the first indicator module 140 corresponds to the fixed position of each electrode sheet corresponding to a size grade of a belt loop, and each second indicator is set at a position adjacent to a group of matching pieces, that is, each second indicator corresponds to a size grade of a belt loop. During the use of the electrode belt, the size grade of the belt loop of the object to be measured is determined by the second indicator, and the setting position of each electrode sheet is determined by the first indicator. The electrode sheet is adjusted to a fixed position corresponding to the size grade of the object to be measured, thereby achieving uniform and accurate distribution of each electrode sheet.

[0043] In specific implementation, in the electrode strip provided in the embodiment of the present application, the first indicator and the second indicator have a variety of structures to realize their functions, the first indicator and the second indicator are marking objects, the appearance features of each first indicator in each group of first indicators are the same, and the appearance features of the first indicators in each group are different; the appearance features of each second indicator are the same as the appearance features of the corresponding group of first indicators; wherein the appearance features include color and shape.

[0044] The marker may be a mark of different colors and / or shapes. The marker may be fixed to the corresponding position of the belt body by dye, coating or pasting. For example, if the marker is a rectangular color block of different colors, the first indicator module includes three groups of first indicators, and the second indicator module includes three second indicators, the first group of first indicators and the second indicators corresponding to the first group of first indicators are red rectangular color blocks, the second group of first indicators and the second indicators corresponding to the second group of first indicators are yellow rectangular color blocks, and the third group of first indicators and the second indicators corresponding to the third group of first indicators are blue rectangular color blocks; when the connecting piece of the belt body is used to connect with the corresponding matching piece, according to the color of the rectangular color block corresponding to the matching piece, the electrode sheet is slid to the position of the rectangular color block of the same color and fixed.

[0045] In a possible implementation, the first indicator is an indicator light, and the second indicator is a switch; the light colors of the first indicator members in each group of first indicator members are the same, and the light colors of the first indicator members in each group are different; each switch is used to light up a group of indicator lights.

[0046] In the case where the first indicator is an indicator light and the second indicator is a switch, each group of indicator lights is connected to the power supply end through the corresponding switch, wherein the circuit formed by each indicator light and each switch can be a flexible circuit, and the power supply end can be connected to an external power supply device. Taking the first indicator module including three groups of first indicator members and the second indicator module including three second indicator members as an example, the first indicator members of the first group are red indicator lights, the first indicator members of the second group are yellow indicator lights, the first indicator members of the third group are green indicator lights, the second indicator members corresponding to the first indicator members of the first group are the first switch, the second indicator members corresponding to the first indicator members of the second group are the second switch, and the second indicator members corresponding to the first indicator members of the third group are the third switch, each red indicator light is connected to the power supply end through the first switch, each yellow indicator light is connected to the power supply end through the second switch, and each green indicator light is connected to the power supply end through the third switch; when the connecting member of the waistband body is used to connect with the corresponding matching member, the corresponding indicator light is turned on according to the corresponding switch of the matching member, and the electrode sheet is slid to the position of the lit indicator light and fixed.

[0047] In a possible implementation manner, the electrode belt may also be provided with: a power supply;

[0048] The power supply is connected to a corresponding set of indicator lights via switches, and the power supply is used to power the indicator lights. The power supply can be set at the end of the first side of the belt body, and the first side refers to the side of the belt body where the electrode sheet, the flexible electrode slide rail, the first indicator module and the second indicator module are not set. By setting the power supply at the end of the first side of the belt body, the power supply will not contact the object to be measured during use, reducing the squeezing of the abdomen of the object to be measured and improving the comfort of using the electrode belt. In addition, the power supply can be a micro power supply.

[0049] In one possible implementation, see Figure 3 As shown, the electrode belt may also be provided with: two symmetrically arranged massage components 180;

[0050] The massage component 180 includes an elastic belt body 181 and a massage ball 182 ; the massage ball 182 is fixedly disposed on the elastic belt body 181 , and the elastic belt body 181 is connected to the waist belt body.

[0051] exist Figure 3In the electrode belt shown, the symmetrically arranged massage components 180 can massage the shoulder blades on both sides of the subject to be tested to relieve the muscle soreness caused by the subject to be tested lying flat for a long time; in addition, by observing the symmetrically arranged massage components 180, it is also possible to determine whether the electrode belt is worn horizontally, that is, if there is a high and a low situation in the symmetrically arranged massage components 180, it means that the electrode belt is worn at an angle. The massage ball 182 mainly plays a massage role, and the setting of the elastic belt body 181 can make the position of the massage ball 182 adjustable to match the subjects to be tested with different body dimensions. The elastic belt body 181 in the massage component 180 is detachably connected to the belt body.

[0052] In a possible implementation, a side of the elastic band body that contacts the object to be measured is provided with an adhesive coating, which is used to attach the massage ball to the shoulder blade of the object to be measured, so as to make the massage more precise.

[0053] In one possible implementation, see Figure 4 As shown, the electrode belt may also be provided with: a temperature sensor 190, which is provided on one side of the flexible electrode slide rail and is used to collect the body surface temperature of the object to be measured.

[0054] exist Figure 4 In the electrode belt shown, by setting the temperature sensor 190 on one side of the flexible electrode slide rail, the temperature sensor 190 can be brought into contact with the skin of the object to be measured, so that the temperature sensor 190 can accurately detect the body surface temperature of the object to be measured, so as to realize real-time body temperature monitoring of the object to be measured. In addition, in order to obtain the body temperature data collected in real time by the temperature sensor 190, a communication module is provided on the electrode, the first end of the communication module is electrically connected to the temperature sensor, and the second end of the communication module is connected to the external electrical impedance imaging terminal in a wired or wireless manner. The communication module is used to send the body temperature data collected in real time by the temperature sensor to the external electrical impedance imaging terminal, so that the external electrical impedance imaging terminal can display and monitor the body temperature of the object to be measured.

[0055] Based on the same concept, the present invention also provides an electrical impedance imaging device, see Figure 5 As shown, the electrical impedance imaging device 200 comprises: an electrical impedance imaging terminal 210 and the electrode belt 100 provided in the embodiment of the utility model;

[0056] The electrode belt 100 and the electrical impedance imaging terminal 210 are connected via an electrode wire.

[0057] In practical applications, the impedance imaging terminal 210 transmits electrical signals to the electrode sheets in the electrode belt 100 through electrode lines. The impedance imaging terminal 210 obtains data for image reconstruction by alternately stimulating two adjacent electrodes and measuring the potential differences between the remaining electrodes to achieve impedance imaging.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0059] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
