Description

Technical Field

[0001] The invention belongs to the field of medical consumables, and in particular relates to a button-type electrode sheet for magnetic resonance imaging. Background Art

[0002] Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that mainly uses the magnetic resonance phenomenon generated by the external magnetic field and the hydrogen nuclei in the human body when a specific radio frequency pulse acts on it, and finally forms an image through professional equipment. Magnetic resonance imaging has high resolution for soft tissue imaging and is very rich in content, such as heart examination, vascular examination, bone marrow and pelvic organ examination, and can also examine a variety of diseases, such as glomerulonephritis, cirrhosis, cerebral infarction, spinal cord tumors, mediastinal tumors, etc. It is currently a commonly used diagnostic examination method in clinical practice.

[0003] Static electricity artifact is one of the artifacts of magnetic resonance imaging. Due to the dry skin of the patient or the static electricity generated by the friction of clothing made of materials such as nylon, these static electricity interferes with the magnetic resonance signal and produces magnetic resonance static electricity artifact. Static electricity artifact has a significant impact on the quality of magnetic resonance imaging, which may cause the image to be unable to accurately reflect the true condition of human tissue, thereby affecting the doctor's diagnosis.

[0004] The working principle of the human body static eliminator is to contact the human body through a metal material with good conductive properties, introduce the static charge of the human body into the metal material and connect the ground wire to introduce the charge into the ground. The static eliminator used in the magnetic resonance room needs to use demagnetizing metal. The common elimination devices in the magnetic resonance room generally include electrode sheets, snap-type static connectors, and ground wires. By sticking the electrode sheets to various parts of the human body, static electricity is eliminated in different parts of the human body. Among them, the snap-type connector needs to be connected to a specific type of electrode sheet, and the connection effect is tight, but the connection operation requires certain skills. It is necessary to pinch the patient's skin at the electrode, and then connect the buttonhole on the snap-type connector to the button body of the electrode sheet in a loop-like manner. When the patient is thin or the medical staff's operation technique is too heavy, there is no fat buffer, which 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

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] 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: Figure 1-Figure 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.

[0019] 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.

[0020] 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.

[0021] In this embodiment, the boss 2 is connected with two traction frames 8, and multiple traction frames are extended laterally from 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 by welding glue. The two traction frames 8 are arranged symmetrically in pairs, and the traction frames 8 and the extrusion plate 6 are on the same central axis.

[0022] In this embodiment, the traction frame 8 is composed of an arc-shaped body 8a and a plate-shaped body 8b, 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 shape as a whole, the inner edges of the arc-shaped body 8a and the plate-shaped body 8b form a disconnected gap, the plate-shaped body 8b is attached to the surface of the multi-insulating layer, the inner edge of the plate-shaped body 8b is connected to the sleeve 7, and the sleeve 7 passes through the inner hole of the multi-insulating layer 5.

[0023] In this embodiment, the surfaces of the contact piece 4 and the sleeve 7 are coated with a conductive adhesive layer 9, which is tightly coated on the surfaces of the contact piece 4 and the sleeve 7. The edge of the area of ​​the conductive adhesive layer 9 is the lower surface of the multi-insulating layer 5. The conductive adhesive layer 9, the multi-insulating layer 5, and the sleeve 7 together wrap the contact piece 4, so that the contact piece 4 forms a sealed shape, 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-insulating layer 5, and the remaining area of ​​the lower surface of the multi-insulating layer 5 is coated with an adhesive layer 10.

[0024] In this embodiment, when the button body 1 is connected to the inner surface of the buttonhole of the button joint 12 in a slip-on manner, the distance between the inner side of the extrusion plate 6 and the side surface of the button 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 connection difficulties caused by resistance from the extrusion plate 6 when pressing the upper surface of the button joint 12 with fingers.

[0025] In this embodiment, since the traction frame 8 connects the extrusion plate 6 and the sleeve 7, when the overall structure formed by the button body 1, the boss 2, the connecting column 3, and the contact piece 4 is subjected to a vertical downward force at the same time, according to Newton's third law, when the inner edges of the fingertips of the two fingers press against the inner circle of the traction frame 8 and apply an inward extrusion force to the outer side of the extrusion plate 6, the friction between the outer side of the extrusion plate 6 and the traction frame 8 increases, which 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. At the same time, since the inner side of the traction frame 8 is supported by the outer surface of the fingertips, the friction between the sleeve 7 and the contact piece 4 increases, which avoids the button body, the boss, the connecting column, and the contact piece. The overall structure is prevented from squeezing the tissue when the buttonhole on the connecting button connector is connected to the button body of the electrode sheet, causing pain to the patient, and the connection difficulty is greatly reduced for medical staff.

[0026] In this embodiment, the outer surface of the joint between 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 to increase the traction effect. The accessories of this device are all demagnetizing materials, among which the button body 1, the boss 2, the connecting column 3, and the contact sheet 4 are conductive materials, which are conducive to the conduction of static electricity in the human body. The conductive material is a metal conductive material, and the metal conductive material is preferably a 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 adhesion, which is convenient for the hydrogel to wrap the contact sheet 4, so that the contact sheet 4 forms a sealed shape and increases the conductive efficiency.

[0027] In this embodiment, the traction frame 8, the sleeve 7, and the extrusion plate 6 are made of non-conductive materials, and the non-conductive materials contain glass fibers. The traction frame 8 containing the glass fiber material increases the traction effect of the traction frame 8. At the same time, the traction frame 8, the sleeve 7, and the extrusion plate 6 made of non-conductive materials have no conductivity, thereby preventing them from contacting the boss 2 and the contact sheet 4 and affecting the conduction of static electricity on the boss 2 and the contact sheet 4.

[0028] In this embodiment, the adhesive layer 10 contains absorbent fibers at the point where it adheres to the human body to prevent sweat and water stains from affecting the stickiness of the adhesive layer 10. The outer surfaces of the button body 1 and the boss 2 are coated with an oxide layer to prevent oxidation from reducing the conductive performance of the conductive metal.

[0029] In this embodiment, the inner circle of the traction frame 8 can accommodate the circumference of the fingertip of an adult's index finger or middle finger.

[0030] The working process of this embodiment specifically includes the following steps: S1: attaching the device to the body part where static electricity needs to be eliminated through the adhesive layer 10; S2: Align the buttonhole of the button joint 12 with the button body 1; S3: insert the index finger and the middle finger into the inner circle of the traction frame 8 to form a whole; S4: Use the thumb to press against the upper surface of the button joint 12 and apply downward force. At the same time, the fingertips of the index finger and the middle finger press against the inner circles of the two traction frames 8 respectively. The friction between the sleeve 7 and the contact piece 4 increases, and the upward traction 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 is increased. The inner edges of the fingertips of the index finger and the middle finger press against the inner circle of the traction frame 8 and apply an extrusion force to the inner side of the extrusion plate 6. The upward friction between the extrusion plate 6 and the outer surface of the traction frame 8 increases (such as Figure 8 As shown), the downward pressure on the button body 1, the boss 2, the connecting column 3, and the contact piece 4 is further blocked, thereby preventing the contact piece 4 from pressing down on the skin and causing pain to the patient.

[0031] The present invention has been specifically described above in conjunction with the embodiments. Various improvements can still be made without departing from the core scope of the present invention, and equivalents can be used to replace the components therein. As long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be used in combination with each other in any way. These combinations are not exhaustively described in this specification, which is only for the purpose of saving space and resources.
