Description

Technical Field

[0001] The utility model relates to the technical field of sweat-absorbing elastic clothing, in particular to a multifunctional elastic clothing for non-invasive cardiac output measurement. Background Art

[0002] The non-invasive cardiac output measurement device can be used to measure the hemodynamics of the human body at rest and during exercise. The device emits 6 wires connected side by side from the instrument box. The ends of the wires are respectively equipped with electrodes for connecting to 6 parts of the human body to detect electrical pulses. In routine examinations, it is necessary to measure the cardiac output of the patient at rest and during exercise. Among them, the exercise measurement requires the patient to wear the device to complete a 6-minute walking test or a bicycle pedal test. As the speed of exercise increases, the friction between the clothes and the inner wires and the body heats up and sweats, the electrodes are very likely to fall off or shift, affecting the image quality. Second, because the wires are not tightly fitted to the human body, they are prone to shaking or even entangled with each other during the exercise test, accelerating the displacement and falling off of the electrodes. Third, in clinical testing, because the clothing of outpatients is often not conducive to the placement of electrodes and wires, the body of the person being tested is partially exposed during the test, which inevitably affects the person's psychology and the experiment.

[0003] The technical solution in the prior art that is closest to the proposal of this application is:

[0004] [China Utility Model] CN202321055529.4 Compression garment suitable for various electrocardiogram-derived examinations

[0005] The patented elastic garment can attach the wires and electrodes to the skin more firmly, but the direct contact between the wires and the skin causes strong discomfort and increases the friction between the wire electrodes and the elastic garment, which in turn accelerates the wires from falling off. In addition, the wires may still become entangled with each other during the measurement process.

[0006] [Chinese Invention] CN202211598968.X A stretch garment for fixing electrocardiogram electrodes

[0007] This invention builds on the existing design by incorporating snaps to secure the current-carrying wires to the detection electrodes, placing the wires on the outside of the elastic garment to reduce friction and discomfort. However, the snaps are fixed in position and fail to account for differences in the position of the detection electrodes for different body types, resulting in reduced measurement accuracy. The existing technology suffers from the following problems:

[0008] The impedance cardiogram machine currently used in hospitals is a simple electrode lead device, which has the following disadvantages:

[0009] 1. The electrodes are easy to move and fall off during motion measurement;

[0010] 2. The electrodes cannot be fixed accurately and symmetrically when switching from the resting measurement position to the movement measurement position;

[0011] 3. The wire harness is prone to shaking and entanglement during motion measurement;

[0012] 4. There is a risk of privacy exposure during the examination;

[0013] 5. Elastic clothing cannot adapt to subjects with different body shapes;

[0014] The technical solution closest to the proposal of this application is (CN116889409A) a stretch garment for fixing ECG detection electrodes. This technical solution has the following disadvantages:

[0015] The original technical solution had wires suspended in front of clothing, which could cause them to sway or even get tangled during exercise, affecting measurement accuracy and the subject's comfort.

[0016] Due to differences in body shape, the position of the electrodes fixed by the elastic garment is not flexible and accurate enough, resulting in large errors in the measurement data or poor signals that cannot be measured. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figure 1-5 As shown, the utility model provides a multifunctional elastic garment for non-invasive cardiac output measurement, including an elastic garment main body 1, a left zipper 2 is provided on the left side of the elastic garment main body 1, a right zipper 3 is provided on the right side of the elastic garment main body 1, a front pocket 4 is fixedly installed on the left side of the front of the elastic garment main body 1, and a data collection instrument box is provided in the inner cavity of the front pocket 4, four porous electrode fixing rings 6 are provided on the front of the elastic garment main body 1, two porous electrode fixing rings 2 7 are provided on the back side of the elastic garment main body 1, electrode sheets 62 are provided on the inner sides of the porous electrode fixing rings 6 and the porous electrode fixing rings 2 7, and wire heads 64 are provided on the outer sides, the electrode sheet connector 63 on the electrode sheet 62 passes through the porous electrode fixing rings 6 and the porous electrode fixing rings 2 7 and is connected to the wire head 64, and the wire on the wire head 64 is fixed by a wire fixing buckle mechanism.

[0039] Place the data collection instrument box into the front pocket 4 on the left side of the elastic garment main body 1 and connect it to the wire. When measuring in the resting state, the wire is connected to the wire head 64 on the front of the elastic garment main body 1 to measure the cardiac output in the resting state. When measuring in the exercise state, it is necessary to remove the wire of the porous electrode fixing ring 6 on the front chest and connect it to the porous electrode fixing ring 2 7 at the symmetrical position of the back. Since the porous electrode fixing ring 2 7 on the back is designed symmetrically with the corresponding position of the front chest, the perforation position of the porous electrode fixing ring 2 7 on the back is determined by the fixed position of the porous electrode fixing ring 6 on the front chest to ensure the symmetry of the front and back positions and measure the cardiac output in the exercise state. After the test is completed, the subject can take off the elastic garment main body 1, remove the porous electrode fixing ring 6, the porous electrode fixing ring 2 7 and the wire, and tidy up the equipment.

[0040] like Figure 1-5 As shown, the four porous electrode fixing rings 6 and the two porous electrode fixing rings 2 7 are each provided with a number of insulating silicone holes 61 that pass through from front to back, and a number of electrode sheets 62 are provided on the inner side of the elastic garment body 1, and electrode sheet connectors 63 are fixedly installed on one side of the several electrode sheets 62, and the several electrode sheet connectors 63 respectively pass through the elastic garment body 1 and the insulating silicone holes 61, and a wire head 64 is provided on one side of the four porous electrode fixing rings 6 and the two porous electrode fixing rings 2 7, and the several electrode sheet connectors 63 are respectively electrically connected to the several wire heads 64, and the input ends of the several wire heads 64 are electrically connected to the data collection instrument box in the inner cavity of the front pocket 4 using wires.

[0041] According to the body shape of the subject, the electrode piece connector 63 of the electrode piece 62 is passed through the appropriate insulating silicone hole groove 61 in the porous electrode fixing ring 6. The insulating silicone hole groove 61 is densely arranged to adapt to the fine-tuning requirements of different body shapes and measurement point positions. By selecting the insulating silicone hole groove 61 in different positions, it is ensured that the porous electrode fixing ring 6 is accurately attached to the position required for measurement. Each porous electrode fixing ring 6 and the corresponding wire head 64 use the same color coding to facilitate corresponding connection and reduce incorrect operation. Connect the electrode piece 62 to the wire head 64 of the corresponding color on the outside of the elastic garment body 1 to form Figure 4 connection structure.

[0042] like Figure 1-5 As shown, a plurality of wire fixing buckle mechanisms 5 are evenly arranged on the front and back of the elastic garment body 1. The wire fixing buckle mechanism 5 includes an adhesive patch 51. An elastic buckle 52 is fixedly installed on the front of the adhesive patch 51. The input end wires of a plurality of wire heads 64 are respectively clamped between two adjacent elastic buckles 52.

[0043] The wire is fixed along the elastic buckle 52 on the adhesive patch 51 on the outer surface of the elastic garment body 1 to ensure that the wire does not shake or get tangled during exercise, thereby improving the stability of the measurement.

[0044] The following is a detailed description of the working principle of the multifunctional elastic garment used for non-invasive cardiac output measurement.

[0045] like Figure 1-5 As shown, the subject takes off his shirt, determines the position of the porous electrode fixing ring 6 at the measuring point and sticks it, selects a stretch garment of appropriate size according to the subject's gender, height and weight, and asks the subject to put on the stretch garment body 1. According to the subject's body shape, the electrode piece connector 63 is passed through the appropriate insulating silicone hole groove 61 in the porous electrode fixing ring 6, and the left zipper 2 and the right zipper 3 are pulled up to make the stretch garment body 1 fit tightly to the body. The insulating silicone hole grooves 61 are densely arranged to meet the fine-tuning requirements of different body shapes and measuring point positions. By selecting the insulating silicone hole grooves 61 at different positions, it is ensured that the porous electrode fixing ring 6 is accurately attached to the required measurement position. Each porous electrode fixing ring 6 and the corresponding wire head 64 are coded with the same color. The electrode piece 62 is connected to the wire head 64 of the corresponding color on the outside of the stretch garment body 1 to form Figure 4 The connection structure is used to fix the wire head 64 along the elastic buckle 52 on the adhesive patch 51 on the outer surface of the elastic garment main body 1 to ensure that the wire will not shake or get tangled during exercise, thereby improving the stability of the measurement. The data collection instrument box is placed in the front pocket 4 on the left side of the elastic garment main body 1 and connected to the wire. During resting state measurement, the wires are connected to all the porous electrode fixing rings 6 on the front of the elastic garment main body 1 to measure the cardiac output in the resting state. During exercise state measurement, the wires of the porous electrode fixing ring 6 on the front chest need to be removed and connected to the porous electrode fixing ring 2 7 at the symmetrical position on the back. Since the porous electrode fixing ring 2 7 on the back is symmetrically designed with the corresponding position on the front chest, the perforation position of the porous electrode fixing ring 2 7 on the back is determined by the fixed position of the porous electrode fixing ring 6 on the front chest to ensure the symmetry of the front and back positions and to measure the cardiac output in the exercise state. After the test is completed, the subject can take off the elastic garment main body 1, remove the porous electrode fixing ring 6 and the porous electrode fixing ring 2 7 and the wires, and tidy up the equipment.

[0046] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
