Description

Technical Field

[0001] The present invention belongs to the field of medical consumables, and particularly relates to a snap electrode sheet for magnetic resonance. Background Art

[0002] Magnetic resonance imaging (MRI) is a non-invasive medical imaging examination technique. It mainly utilizes the magnetic resonance phenomenon generated by the interaction between an external magnetic field and hydrogen atomic nuclei in the human body under the action of a specific radio frequency pulse, and finally forms an image through professional equipment. Magnetic resonance examination has high resolution for soft tissue imaging and rich content. For example, it can be used for heart examination, blood vessel examination, bone marrow and pelvic organ examination, and can also detect various diseases such as glomerulonephritis, cirrhosis, cerebral infarction, spinal cord tumors, mediastinal tumors, etc. It is a commonly used diagnostic examination method in clinical practice.

[0003] Electrostatic artifacts are one of the artifacts in magnetic resonance imaging. Due to dry skin of the patient or static electricity generated by friction of clothing made of materials such as nylon, these static electricity interfere with the magnetic resonance signals, resulting in magnetic resonance electrostatic artifacts. Electrostatic artifacts have a significant impact on the quality of magnetic resonance imaging, which may cause the image to not accurately reflect the true situation of human tissues, thereby affecting the doctor's diagnosis.

[0004] The working principle of a human body static eliminator is to contact the human body through a metal material with good electrical conductivity, conduct the static charge of the human body into the metal material and connect the ground wire to conduct the charge into the ground. The static elimination device used in a magnetic resonance room needs to use a demagnetized metal. The common elimination devices in a magnetic resonance room generally include electrode sheets, snap electrostatic connectors, and ground wires. By attaching the electrode sheets to various parts of the human body, static electricity can be eliminated from different human body parts. Among them, the snap connector needs to be connected to a specific model of electrode sheet, and the connection effect is tight. However, the connection operation requires certain skills. It is necessary to pinch the skin at the electrode of the patient, and then connect the buttonhole on the snap connector to the button body of the electrode sheet in a loose sleeve manner. When the patient is thinner or the medical staff's operation technique is too heavy, without the buffer of fat, it may cause pain to the patient. For medical staff, it also increases the difficulty of connection. Therefore, a new technology is needed to improve this phenomenon. Summary of the Invention

[0005] Aiming at the above problems in the prior art, the present invention provides a snap electrode sheet for magnetic resonance, an anti-static interference snap electrode sheet that can be used in a magnetic resonance room, which avoids the problems of causing pain to the patient and high connection difficulty when connecting the buttonhole on the snap connector to the button body of the electrode sheet.

[0006] The present invention is implemented through the following technical solutions. A button electrode sheet for magnetic resonance includes a multi-insulation layer. The multi-insulation layer is arranged longitudinally. A boss is provided on the upper surface of the multi-insulation layer. The boss is located at the center of the upper surface of the multi-insulation layer. A button body is provided on the upper part of the boss. The button body is in a convex shape. The outer surface of the button body can be sleeved and connected with the inner surface of the buttonhole of a button-type connector.

[0007] The lower part of the boss is connected to the upper part of a connecting column. The connecting column penetrates through the multi-insulation layer. The lower part of the connecting column is connected to the upper surface of a contact piece. The contact piece is a cylindrical sheet. The upper surface of the contact piece is closely attached to the lower surface of the multi-insulation layer. A socket is tightly provided on the edge and side of the lower surface of the contact piece. The edge and side of the lower surface of the contact piece are tightly and embeddedly attached to the inner wall of the socket.

[0008] At least two pressing plates are provided on the edge of the boss. At least two of the pressing plates are arranged symmetrically in pairs. At least two traction frames are connected to the boss. The front end of the traction frame is connected to the outer side surface of the boss through welding glue. At least two of the traction frames are arranged symmetrically in pairs. The traction frame and the pressing plate are on the same central axis.

[0009] The traction frame is composed of an arc-shaped body and a plate-shaped body connected. The outer edges of the arc-shaped body and the plate-shaped body are connected. The arc-shaped body and the plate-shaped body form a folded-back shape as a whole. A disconnection gap is formed between the inner edges of the arc-shaped body and the plate-shaped body. The plate-shaped body is attached to the surface of the multi-insulation layer. The inner edge of the plate-shaped body is connected to the socket. The socket penetrates the inner hole of the multi-insulation layer.

[0010] A conductive glue layer is coated on the surfaces of the contact piece and the socket. The conductive glue layer is tightly coated on the surfaces of the contact piece and the socket. The edge of the area of the conductive glue layer is the lower surface of the multi-insulation layer. The conductive glue layer, the multi-insulation layer, and the socket jointly wrap the contact piece, making the contact piece form a sealed shape. The area coated with the conductive glue layer is located at the center of the lower surface of the multi-insulation layer. The remaining area of the lower surface of the multi-insulation layer is coated with an adhesive glue layer.

[0011] When the button body is sleeved and connected with the inner surface of the buttonhole of the button-type connector, the distance between the inner side of the pressing plate and the side surface of the button-type connector ≥ 0 cm, and the distance between the inner sides of the symmetrically arranged pressing plates ≥ 1.5 cm.

[0012] Furthermore, the outer surface of the connection part between the arc-shaped body and the plate-shaped body is connected to the upper surface of the multi-insulation layer through an adhesive structure.

[0013] Furthermore, all components of the present device are made of demagnetized materials. Among them, the button body, the boss, the connecting column, and the contact piece are made of conductive materials.

[0014] Furthermore, the conductive adhesive layer is a hydrogel conductive adhesive layer.

[0015] Furthermore, the traction frame, the socket, and the pressing plate are made of non-conductive materials, and the non-conductive materials contain glass fibers.

[0016] Furthermore, the adhesive layer at the adhesion part with the human body contains water-absorbing fibers.

[0017] Furthermore, the outer surfaces of the button body and the boss are coated with oxide layers.

[0018] Furthermore, the inner circle of the traction frame can accommodate the fingertip circumference of an adult's index finger or middle finger.

[0019] Beneficial effects: The present invention is made of non-magnetic conductive materials and can be used in a magnetic resonance room. Since the traction frame is connected to the pressing plate and the socket, when the overall structure formed by the button body, the boss, the connecting column, and the contact piece is simultaneously subjected to a vertically downward force, according to Newton's third law, due to the supporting force exerted by the outer surface of the finger between the fingers against the inner circle of the traction frame, the friction between the socket and the contact piece increases, increasing the upward traction force of the overall structure formed by the button body, the connecting column, the contact piece, and the traction frame. At the same time, when the inner edges of the fingertips of the two fingers are against the inner circle of the traction frame, an inward pressing force is applied to the outside of the pressing plate, increasing the friction between the outside of the pressing plate and the outer surface of the traction frame, avoiding the pain caused to the patient by squeezing the tissue when connecting the buttonhole on the connecting buckle to the button body of the electrode piece, and for medical staff, the connection difficulty is greatly reduced.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] This embodiment is implemented by the following technical solutions. To solve the above problems in the prior art, the present invention provides the present invention implemented by the following technical solutions: Figures 1-8 As shown, a button-type electrode sheet for magnetic resonance includes multiple insulating layers 5, which are arranged longitudinally. A boss 2 is provided on the upper surface of the multiple insulating layers 5, and the boss 2 is located in the center of the upper surface of the multiple insulating layers 5. A button body 1 is provided on the upper part of the boss 2. The button body 1 is in a convex shape, and the outer surface of the button body 1 can be connected with the inner surface of the buttonhole of the button-type joint 12 in a slip-on manner.

[0031] In this embodiment, the lower part of the boss 2 is connected with the upper part of the connecting column 3, the connecting column 3 passes through the multiple insulating layers 5, the lower part of the connecting column 3 is connected with the upper surface of the contact piece 4, the contact piece 4 is a cylindrical sheet, the upper surface of the contact piece 4 is tightly fitted with the lower surface of the multiple insulating layer 5, and the edge and side of the lower surface of the contact piece 4 are provided with a sleeve 7. The edge and side of the lower surface of the contact piece 4 are tightly fitted with the inner wall of the sleeve 7 through embeddedness. The tight fit makes the button body 1, the boss 2, the connecting column 3, and the contact piece 4 subject to a vertical downward force. The inner circle of the traction frame 8 is subjected to the upward traction force pressed by the fingertips, thereby increasing the friction between the sleeve 7 and the contact piece 4.

[0032] Two extrusion plates 6 are provided on the edge of the boss 2, and the two extrusion plates 6 are symmetrically arranged in pairs. The outer surface of the extrusion plate 6 is rough. When the outer side of the extrusion plate 6 is subjected to inward extrusion force, the friction between the outer side of the extrusion plate 6 and the traction frame 8 increases, which hinders the downward pressure on the button body 1, the boss 2, the connecting column 3, and the contact piece 4.

[0033] In this embodiment, two traction frames 8 are connected to the boss 2. Multiple traction frames extend horizontally at the lower part of the outer side surface. The lower part of the outer side surface of the boss 2 is connected to the front end of the traction frame 8 through welding glue. The two traction frames 8 are arranged symmetrically in pairs, and the traction frame 8 and the extrusion plate 6 are on the same central axis.

[0034] In this embodiment, the traction frame 8 is composed of an arc-shaped body 8a and a plate-shaped body 8b connected. The outer edges of the arc-shaped body 8a and the plate-shaped body 8b are connected. The arc-shaped body 8a and the plate-shaped body 8b form a folded-back shape as a whole. A disconnection gap is formed at the inner edges of the arc-shaped body 8a and the plate-shaped body 8b. The plate-shaped body 8b adheres to the surface of the multi-insulation layer, and the inner edge of the plate-shaped body 8b is connected to the socket 7, and the socket 7 penetrates the inner hole of the multi-insulation layer 5.

[0035] In this embodiment, a conductive adhesive layer 9 is coated on the surfaces of the contact piece 4 and the socket 7. The conductive adhesive layer 9 is tightly coated on the surfaces of the contact piece 4 and the socket 7. The edge of the area of the conductive adhesive layer 9 is the lower surface of the multi-insulation layer 5. The conductive adhesive layer 9, the multi-insulation layer 5, and the socket 7 jointly wrap the contact piece 4, so that the contact piece 4 forms a sealed state, further increasing the conductive efficiency; the area coated with the conductive adhesive layer 9 is located in the center of the lower surface of the multi-insulation layer 5, and the remaining area of the lower surface of the multi-insulation layer 5 is coated with an adhesive layer 10.

[0036] In this embodiment, when the button body 1 is connected in a loose-fitting manner to the inner surface of the buttonhole of the snap joint 12, the distance between the inner side of the extrusion plate 6 and the side surface of the snap joint 12 is ≥0 cm, and the distance between the inner sides of the symmetrically arranged extrusion plates 6 is ≥1.5 cm, so as to avoid the difficulty of connection caused by being resisted by the extrusion plate 6 when pressing the upper surface of the snap joint 12 with a finger.

[0037] In this embodiment, since the traction frame 8 is connected to the extrusion plate 6 and the socket 7, when the overall structure formed by the button body 1, the boss 2, the connecting column 3, and the contact piece 4 is simultaneously subjected to a vertically downward force, according to Newton's third law, when the inner edges of the fingertips of two fingers resist the inner circle of the traction frame 8 and apply an inward squeezing force to the outside of the extrusion plate 6 at the same time, the frictional force between the outside of the extrusion plate 6 and the traction frame 8 increases, hindering the downward pressure received by the overall structure formed by the button body 1, the boss 2, the connecting column 3, and the contact piece 4. At the same time, since the inner side of the traction frame 8 receives the supporting force resisted by the outer surface of the finger tip, the frictional force between the socket 7 and the contact piece 4 increases, avoiding the pain caused by squeezing the tissue when connecting the buttonhole on the snap joint and the button body of the electrode piece for the overall structure formed by the button body, the boss, the connecting column, and the contact piece, and for medical staff, the connection difficulty is greatly reduced.

[0038] In this embodiment, the outer surface of the junction of the arc-shaped body 8a and the plate-shaped body 8b is connected to the upper surface of the multi-insulation layer 5 through the adhesive structure 11, which increases the traction effect. All the fittings of this device are demagnetized materials. Among them, the button body 1, the boss 2, the connecting column 3, and the contact piece 4 are conductive materials, which are conducive to the conduction of human body static electricity. The conductive material is a metal conductive material, and the metal conductive material is preferably copper material. The copper material is demagnetized. The conductive adhesive layer 9 is a hydrogel conductive adhesive layer 9. The hydrogel conductive adhesive layer 9 has good conductivity, fluidity, and adhesiveness, which is convenient for the hydrogel to wrap the contact piece 4, so that the contact piece 4 forms a sealed state, increasing the conductive efficiency.

[0039] In this embodiment, the traction frame 8, the socket 7, and the extrusion plate 6 are non-conductive materials. The non-conductive materials contain glass fibers. The traction frame 8 containing glass fiber materials increases the traction effect of the traction frame 8. At the same time, the traction frame 8, the socket 7, and the extrusion plate 6 made of non-conductive materials have no conductivity, avoiding their contact with the boss 2 and the contact piece 4 and affecting the conduction of static electricity of the boss 2 and the contact piece 4.

[0040] In this embodiment, the adhesive layer 10 contains water-absorbing fibers at the place where it adheres to the human body, avoiding affecting the adhesiveness of the adhesive layer 10 due to reasons such as sweat stains and water stains. The outer surfaces of the button body 1 and the boss 2 are coated with an oxide layer to prevent the reduction of the conductive efficiency of the conductive metal due to oxidation.

[0041] In this embodiment, the inner circle of the traction frame 8 can accommodate the fingertip circumference of an adult index finger or middle finger.

[0042] The working process of this embodiment specifically includes the following steps:

[0043] S1: Attach this device to the limb part where static electricity needs to be eliminated through the adhesive layer 10;

[0044] S2: Align the buttonhole of the snap joint 12 with the button body 1;

[0045] S3: Insert the index finger and middle finger into the whole formed by the inner circle of the traction frame 8 respectively;

[0046] S4: Press the upper surface of the snap joint 12 with the thumb and apply a downward force. At the same time, the fingertip surfaces of the index finger and middle finger respectively press against the inner circles of the two traction frames 8, increasing the friction between the socket 7 and the contact piece 4, increasing the upward traction force of the overall structure formed by the button body 1, the boss 2, the connecting column 3, the contact piece 4, and the traction frame 8. The inner edges of the fingertips of the index finger and middle finger apply an inward pressing force towards the inner side of the extrusion plate 6 while pressing against the inner circles of the traction frames 8, increasing the upward frictional force between the inward pressing force received by the extrusion plate 6 and the outer surface of the traction frame 8 (as Figure 8As shown, it further hinders the downward pressure on the overall structure formed by the button body 1, the boss 2, the connecting column 3, and the contact piece 4, thereby preventing the contact piece 4 from pressing down on the skin and causing pain to the patient.

[0047] The present invention has been specifically described above in conjunction with the embodiments. Without departing from the core scope of the present invention, various improvements can still be made, and components can be replaced with equivalents. As long as there is no structural conflict, the features in the disclosed embodiments of the present invention can be combined with each other in any way.
