Technical Field

[0001] The present invention belongs to the field of biological experiment technology, and specifically relates to a wearable bioelectrical signal monitoring and analysis device for experimental rats. Background Art

[0002] In biomedical research, laboratory rats are widely used in various experimental studies due to their physiological similarities to humans. Monitoring and analyzing bioelectrical signals in laboratory rats can provide critical data for studying disease mechanisms and evaluating drug efficacy. Waistband-type bioelectrical signal detection devices are typically designed to be conveniently fastened around the waist of sleeping rats and other laboratory animals to collect bioelectrical signals such as electrocardiogram (ECG), electroencephalogram (EEG), and body temperature.

[0003] However, existing belt-type bioelectric signal detection devices for monitoring experimental rats in a sleeping state generally connect electrodes directly to the experimental rats and then transmit the signals to the monitoring equipment. In order to obtain more accurate data, the belt-type bioelectric signal detection devices generally need to fit tightly with the rats. When in a tightly fitting state for a long time, the rats' waists are always in a tight state, causing strong discomfort and making it difficult to provide a comfortable sleeping experience. Moreover, when monitoring, the existing monitoring devices do not have an ideal fit between the electrodes and the rats' skin, making it difficult to obtain more accurate data.

[0004] To this end, we provide a wearable bioelectrical signal monitoring and analysis device for experimental rats to solve the above problems. Summary of the Invention

[0029] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1

[0031] In order to solve the problem that the existing wearable belt-type biomonitoring devices used during sleep need to be kept in a tight state in order to obtain more accurate bioelectrical signal data, but this will cause discomfort to the rats and make it difficult to provide a comfortable sleeping experience, please refer to Figure 1-Figure 2 、 Figure 4The present invention provides a wearable bioelectric signal monitoring and analysis device for experimental rats, comprising a flexible adjustment plate 2 and a plurality of supporting arc plates 1. The flexible adjustment plate 2 and the plurality of supporting arc plates 1 are used to be spliced into a wearable loop. The supporting arc plates 1 are hard plates, and a soft bag can be provided on their surface to improve wearing comfort. A reinforced structural support, such as a metal skeleton or high-strength fiber material, can be used inside to improve the durability and stability of the belt, ensuring that it can maintain a good shape and support effect after long-term wear. The flexible adjustment plate 2 is used to adjust the size of the wearable loop; a connector 3 is provided between adjacent supporting arc plates 1; a movable block 4 is embedded on the inner surface of the supporting arc plate 1, and an electrode sheet 5 for monitoring bioelectric signals is embedded on the inner surface of the movable block 4. A pressure sensing component 7 for feedback of the pressure of the movable block 4 is provided in the internal cavity of the supporting arc plate 1; a control component 8 is provided on the outer surface of one of the supporting arc plates 1, and the control component 8 is used to receive a signal from the pressure sensing component 7 and control the corresponding connector 3 to adjust the tightening state of the wearable loop so that the electrode sheet 5 on the wearable loop is separated from or attached to the rat. By controlling the extension and contraction of the connecting piece 3, the half of the ring located on the upper part of the rat can be separated from the rat, thereby preventing the ring from being in a tightened state all the time, improving the comfort of use, and providing the rat with a comfortable sleeping experience.

[0032] An electric plug 101 is provided on one side of the supporting arc plate 1 and an electric socket 102 is provided on the other side. Adjacent supporting arc plates 1 are electrically connected through the electric plug 101 and the electric socket 102 to facilitate the transmission of monitoring data.

[0033] To improve the device's breathability and reduce discomfort during prolonged wear, the movable block 4 is provided with a first ventilation hole 401. Second ventilation holes 103 are located on both sides of the supporting curved plate 1. The first ventilation holes 401 and the second ventilation holes 103 are in fluid communication. The movable block 4 is made of a breathable, soft, and skin-friendly material. The combination of the first ventilation holes 401 and the second ventilation holes 103 ensures air circulation beneath the rat, reducing heat buildup between the belt device and the skin, thereby alleviating discomfort caused by sweat accumulation.

[0034] like Figure 3 As shown, connector 3 includes a gear 301 rotatably mounted within a supporting curved plate 1 and a rack 303 fixedly mounted within another supporting curved plate 1. Gear 301 meshes with rack 303, and a micromotor 302 is mounted at the end of gear 301 to drive its rotation. A movable cover 104 is hingedly mounted on the supporting curved plate 1 within the mounting cavity of connector 3. During operation, micromotor 302 rotates gear 301, which in turn rotates rack 303, which in turn moves supporting curved plate 1.

[0035] like Figure 7As shown, the flexible adjustment plate 2 is in contact with the supporting arc plate 1; adjustment straps 201 are provided on both sides of the flexible adjustment plate 2, which pass through the supporting arc plate 1 and extend outside the ring. Velcro 202 is provided on the adjustment straps 201. The basic size of the ring can be customized based on the waist size of the rat. The setting of the flexible adjustment plate 2 can further improve the fit of the wearer. At the same time, the flexible adjustment plate 2 can be removed to form a gap for the rat to wear. The specific wearing process is to remove the flexible adjustment plate 2 and open the movable cover 104. At this time, the rack 303 and the gear 301 can be in a separated state. Since the airbag assembly 6 is flexibly connected between the supporting arc plates 1, the ring can be opened. After it is worn to the waist, the rack 303 and the gear 301 are installed, the upper movable cover 104 is closed, and finally the flexible adjustment plate 2 is installed and the tightness is adjusted.

[0036] like Figure 8 As shown, control unit 8 includes a mounting plate 801, one end of which is hinged to the supporting curved plate 1 and the other end is clipped to the supporting curved plate 1. Mounting plate 801 is provided with a pull hole 802, a display screen 803, a switch button 804, and an alarm 805. Control unit 8 is used to analyze and display bioelectrical signal data. Pull hole 802 allows mounting plate 801 to be pulled up, allowing easy viewing of bioelectrical signal parameters on display screen 803. Alarm 805 can be configured as a buzzer, an audible or visual alarm, or other device to alert the experimenter of abnormal data.

[0037] Example 2

[0038] On the basis of Example 1, in order to automatically adjust the tightness of the coil according to the sleeping posture of the rat, Figure 4 As shown, the pressure sensing component 7 includes a fixed metal sheet 701 installed in the supporting arc plate 1 and a movable metal sheet 702 located on the side of the fixed metal sheet 701; a movable rod 703 is fixed on the movable metal sheet 702, the end of the movable rod 703 is fixedly connected to the movable block 4, a fixed seat 704 is sleeved on the movable rod 703, and a spring 705 is sleeved on the movable rod 703 between the fixed seat 704 and the movable metal sheet 702.

[0039] When in use, the movable block 4 moves downward due to the gravity of the rat, driving the movable rod 703 and the movable metal sheet 702 to move downward. At this time, the spring 705 is stretched. When the movable metal sheet 702 contacts the fixed metal sheet 701, the circuit is connected. After receiving the signal, the control component 8 controls the corresponding connecting component 3 to operate; when the sleeping posture of the rat is adjusted, the movable block 4 pressed by it changes. Based on the position of the new pressed movable block 4, the control component 8 adjusts the corresponding connecting component 3 so that the corresponding half of the circle located on the upper part of the rat is separated from the rat.

[0040] Example 3

[0041] On the basis of the first and second embodiments, in order to further solve the problem that the existing wearable belt type monitoring equipment does not fit the electrode sheet 5 to the skin well enough during monitoring, making it difficult to obtain more accurate data, such as Figure 1 、 Figure 5-Figure 6 As shown, it also includes an airbag component 6 for controlling the electrode sheet 5 to fit the rat skin. The airbag component 6 controls multiple electrode sheets 5 to move closer to the rat at the same time, so that the electrode sheet 5 fits tightly with the rat skin, thereby improving the accuracy of monitoring.

[0042] The airbag assembly 6 includes an annular tube 601 located on the side of the ring body, a first capsule 602 located between adjacent supporting arc plates 1, and a second capsule 604 located on the inner surface of the electrode sheet 5; the first capsule 602 is fixedly connected to the supporting arc plate 1, and a first connecting tube 603 is provided between the first capsule 602 and the annular tube 601; the second capsule 604 is fixed in the inner surface cavity of the movable block 4 and is fixedly connected to the electrode sheet 5, and a second connecting tube 605 is provided between the second capsule 604 and the annular tube 601. When it is necessary to collect bioelectric signals, the control component 8 controls the corresponding connecting component 3 that is already in the extended state to reset. At this time, the supporting arc plate 1 is reset under the drive of the connecting component 3. During the resetting process, the supporting arc plate 1 squeezes the first capsule 602, and the gas in the first capsule 602 enters into each second capsule 604 through the first connecting tube 603 and the second connecting tube 605. After the second capsule 604 swells, it drives the electrode sheet 5 closer to the rat skin; after the collection is completed, the control component 8 controls the corresponding connecting component 3 to extend so that the ring is separated from the rat skin. At this time, the supporting arc plate 1 moves under the drive of the connecting component 3. After losing the squeezing force of the supporting arc plate 1, the first capsule 602 elastically recovers, and the gas in the second capsule 604 returns to the first capsule 602.

[0043] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and such modifications and improvements are all within the scope of protection of the present invention.
