Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for monitoring electrode sheet loosening. Background Art

[0002] There are many types of electrode patches, including massage electrode patches, physical therapy electrode patches, self-adhesive electrode patches, medical electrode patches, heating motor patches, etc. The principle of using electrode patches is to stick the electrode patches to the corresponding treatment parts of the human body, so that the positive and negative poles of the therapeutic device are connected, and the pulses generated by the therapeutic device pass through the patch, like countless electric needles to simulate acupuncture and massage therapy. Generally, after the electrode patches are used several times, the adhesive film will not be firmly attached, and will fall off, affecting the use of the electrode patches. Moreover, especially for patients with no perception or poor perception, the electrode patches cannot be reattached in time after falling off, affecting the treatment effect.

[0003] At present, the Chinese patent application with application number CN201820868914.3 discloses a relaxation therapy electrode sheet, which has two binding straps designed on both sides of the therapy electrode sheet, and uses the two binding straps to fix the therapy electrode sheet on the patient to prevent it from falling off, and uses a pressure sensor to monitor whether the therapy electrode sheet is loose. However, in actual operation, multiple electrode sheets are usually used in combination, so there will be a lot of binding straps wrapped around the patient, which reduces comfort, and the operation process is cumbersome and inconvenient to use.

[0004] The Chinese patent application with application number CNCN202222641741.0 discloses an anti-falling physical therapy electrode sheet, which uses a negative pressure adsorption component to assist in positioning the physical therapy electrode sheet. Specifically, after the bottom of the suction cup is in close contact with the human skin, the air inside the suction cup is extracted through the negative pressure tube, the fixed tube and the connecting tube in sequence by a micro vacuum pump, so that the inside is in a negative pressure state, thereby adsorbing the suction cup on the human skin through negative pressure. However, in actual operation, the human body is not a plane, but the multiple suction cups in the above-mentioned Chinese patent application are located on the same plane, and are simultaneously evacuated by the same micro vacuum pump. In this way, it is difficult to form a negative pressure inside the suction cup, making it difficult to assist in positioning the physical therapy electrode sheet; and the loosening of the electrode sheet is not monitored in the Chinese patent application.

[0005] Therefore, it is necessary to design a structure that can monitor whether the electrode sheet is loose and can conveniently and effectively fix the electrode sheet. Summary of the invention

[0006] The present invention is intended to provide an electrode sheet loosening monitoring device, so as to realize reinforcement of the electrode sheet while monitoring the loosening of the electrode sheet.

[0007] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a device for monitoring the loosening of an electrode sheet, comprising a pressure sensor, which is distributed on a side surface of the electrode sheet close to human skin, and also comprising a controller and a pressurized fixing component, the pressure sensor is electrically connected to the controller, the pressurized fixing component comprises an airbag, an annular patch and a flexible pull strip, the middle part of the flexible pull strip is fixedly connected to the airbag, the two ends of the flexible pull strip are respectively fixedly connected to the annular patch, and the line connecting the two connection points of the flexible pull strip and the annular patch passes through the center of the annular patch, and the bottom surface of the annular patch is provided with a first adhesive film; the airbag is connected to an inflation hose, and the end of the inflation hose away from the airbag is connected to an inflation pump, the inflation pump is controlled by the controller, and the controller controls the operation of the inflation pump according to the pressure information transmitted from the pressure sensor.

[0008] The working principle and beneficial effects of this solution are as follows: In this solution, a pressure sensor is placed on human skin in advance, and when the electrode sheet is pasted on human skin, the pressure sensor is covered, and then the ring patch is pasted on human skin so that the ring patch surrounds the periphery of the electrode sheet. The pressure sensor is used to monitor the pressure applied by the electrode sheet to the human skin. If the electrode sheet becomes loose and is about to fall off, the pressure data detected by the pressure sensor decreases, and the controller controls the air pump to inflate the airbag through the air hose, so that the airbag expands and increases in volume, thereby applying a pushing force to the electrode sheet, so that the electrode sheet is closely attached to the human skin, thereby reinforcing the electrode sheet. In this way, this solution can not only monitor the loosening of the electrode sheet, but also reinforce the electrode sheet in time when the electrode sheet is loose, so as to prevent the electrode sheet from loosening and falling off; and this solution can be reused, which is economical and practical.

[0009] Optionally, a plurality of edge ears are provided on the outer circumference of the annular sticker, and a second adhesive film is provided on the bottom surface of the edge ears.

[0010] In this solution, the edge ears are used to increase the adhesion area between the device and the human skin, thereby improving the adhesion between the device and the human skin, thereby ensuring that the annular patch will not fall off after the airbag is inflated.

[0011] Optionally, the device also includes a negative pressure reinforcement component, which includes a plurality of suction cups, the tops of the suction cups are connected to vacuum hoses, and the ends of the vacuum hoses away from the suction cups are connected to vacuum pumps; the edge ears and the second adhesive film are provided with through holes for the vacuum hoses to pass through.

[0012] In this solution, the edge ear is adhered to the suction cup by the second adhesive film. After the suction cup is in close contact with the human skin, the vacuum pump extracts the air in the suction cup through the vacuum hose, so that negative pressure is formed inside the suction cup, thereby achieving the fixation of the edge ear. In this way, after the viscosity of the first adhesive film decreases, the negative pressure reinforcement component still serves as a fulcrum to support the airbag to expand and push the electrode sheet, thereby continuing to achieve the reinforcement of the electrode sheet.

[0013] Optionally, a baffle is connected to one end of the suction hose close to the suction cup, and the baffle is located on a side of the edge ear away from the suction cup.

[0014] In this solution, after the viscosity of the second adhesive film decreases, the blocking sheet can prevent the edge ear from falling off the suction cup and moving away from the suction cup, thereby ensuring that the airbag can exert a pushing force on the electrode sheet after expansion, thereby continuing to reinforce the electrode sheet.

[0015] Optionally, a second one-way valve for directing air out of the suction cup is installed on the suction hose.

[0016] In this solution, the provision of the second one-way valve can ensure that the air in the vacuum hose will not flow back, so that the user can use one vacuum pump to vacuum several suction cups.

[0017] Optionally, the air extraction hose is connected to a return air pipe, the connection point between the return air pipe and the air extraction hose is located between the second one-way valve and the suction cup, and the free end of the return air pipe is provided with a second closing piece for closing the free end of the return air pipe.

[0018] In this solution, when removing the device, the second sealing piece on the air return pipe is removed, and the outside air flows into the suction cup through the air return pipe and the air suction hose, eliminating the negative pressure inside the suction cup, thereby making it easy for the user to remove the suction cup and avoiding discomfort or pain for the patient.

[0019] Optionally, the inflation hose is installed with a first one-way valve for introducing air into the airbag, the inflation hose is connected with an exhaust pipe, the connection point between the exhaust pipe and the inflation hose is located between the first one-way valve and the airbag, and the free end of the exhaust pipe is provided with a first closing piece for closing the free end of the exhaust pipe.

[0020] In this solution, the first one-way valve can ensure that the airflow in the inflation hose does not flow back, thereby ensuring stable expansion of the airbag. When removing the device, the first sealing member on the exhaust pipe is removed, and the air in the airbag is discharged through the inflation hose and the exhaust pipe, and the volume of the airbag is reduced and restored.

[0021] Optionally, a connecting piece is provided between the annular patch and the first adhesive film, and the connecting piece is used to connect the annular patch and the first adhesive film. The connecting piece includes a Velcro hook surface and a Velcro fleece surface. The Velcro hook surface is fixedly connected to the annular patch, and the Velcro fleece surface is fixedly connected to the first adhesive film.

[0022] In this solution, the first adhesive film is connected to the annular adhesive by a connecting piece, so that a new first adhesive film can be replaced after the viscosity of the first adhesive film decreases.

[0023] Optionally, the device further comprises an alarm, which is electrically connected to the controller, and the controller controls the operation of the alarm according to pressure information transmitted from the pressure sensor.

[0024] In this solution, when the pressure data detected by the pressure sensor suddenly decreases significantly, the controller controls the alarm to sound an alarm, alerting the user or medical staff that the electrode sheet is loose or falling off, and that problems such as the ring patch falling off or the airbag leaking may also occur at this time, which require timely processing.

[0025] Optionally, the number of the flexible pull strips is more than two, and the middle parts of the more than two flexible pull strips are overlapped.

[0026] In this solution, when the number of the flexible tie rods is two or more, the pushing force exerted by the inflated airbag on the flexible tie rods can be well dispersed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 1

[0036] This embodiment is basically Figure 1 and Figure 2As shown: a device for monitoring loose electrode sheets, including a pressure sensor 1, an alarm 2, a controller 3 and a pressurized fixing assembly, the pressure sensor 1 and the alarm 2 are both electrically connected to the controller 3, the pressure sensor 1 is distributed on the side of the electrode sheet 4 close to the human skin, and the controller 3 controls the alarm 2 to work according to the pressure information transmitted from the pressure sensor 1. In this embodiment, the number of pressure sensors 1 is four; in addition, the alarm 2 is an audible and visual alarm 2, which warns the user or medical staff through sound signals and light signals.

[0037] The pressurized fixing component includes an airbag 5, an annular patch 6 and a flexible pull strip 7. The middle part of the flexible pull strip 7 is fixedly connected to the airbag 5, and the two ends of the flexible pull strip 7 are respectively fixedly connected to the annular patch 6, and the line connecting the two connection points of the flexible pull strip 7 and the annular patch 6 passes through the center of the annular patch 6; in addition, the number of flexible pull strips 7 is more than two, and the middle parts of the more than two flexible pull strips 7 are overlapped. In this embodiment, the number of flexible pull strips 7 is two.

[0038] Combination Figure 3 and Figure 4 As shown, the bottom surface of the annular patch 6 is provided with a first adhesive film 8. Specifically, a connecting piece is provided between the annular patch 6 and the first adhesive film 8. The connecting piece is used to connect the annular patch 6 and the first adhesive film 8. The connecting piece includes a Velcro hook surface 9 and a Velcro fleece surface 10. The Velcro hook surface 9 is bonded to the annular patch 6, and the Velcro fleece surface 10 is bonded to the first adhesive film 8. A plurality of edge ears 11 are provided on the outer circumference of the annular patch 6, and a second adhesive film 12 is provided on the bottom surface of the edge ears 11. In this embodiment, the edge ears 11 are integrally formed with the annular patch 6, and the number of the edge ears 11 is four, and the four edge ears 11 are evenly distributed along the circumference of the annular patch 6. In addition, the bottom surfaces of the first adhesive film 8 and the second adhesive film 12 are both provided with a release paper layer (not shown).

[0039] The airbag 5 is connected to an inflatable hose 13, and the end of the inflatable hose 13 away from the airbag 5 is connected to an inflatable pump 14, and the inflatable pump 14 is controlled by the controller 3, and the controller 3 controls the operation of the inflatable pump 14 according to the pressure information transmitted from the pressure sensor 1. A first one-way valve 15 for introducing air into the airbag 5 is installed on the inflatable hose 13, and an exhaust pipe 16 is connected to the inflatable hose 13. The connection point between the exhaust pipe 16 and the inflatable hose 13 is located between the first one-way valve 15 and the airbag 5. The free end of the exhaust pipe 16 is provided with a first sealing member 17 for sealing the free end of the exhaust pipe 16. In this embodiment, the first sealing member 17 is threadedly connected to the free end of the exhaust pipe 16.

[0040] When in use, after cleaning the patient's skin where the electrode sheet 4 is to be pasted, place the pressure sensor 1 on the cleaned human skin, and then paste the electrode sheet 4 on the human skin at the corresponding position and cover the pressure sensor 1; then paste the ring patch 6 on the human skin at the corresponding position and make the ring patch 6 surround the outer periphery of the electrode sheet 4 (at this time, the first adhesive film 8 is adhered to the human skin at the corresponding position), and then paste the edge ear 11 on the human skin through the second adhesive film 12. At this point, the preparation work is completed.

[0041] As the use time goes by, the adhesion between the electrode sheet 4 and the human skin decreases, and the electrode sheet 4 becomes loose. At this time, the pressure data detected by the pressure sensor 1 decreases, and the controller 3 controls the air pump 14 to start, and inflates the airbag 5 through the inflation hose 13, so that the airbag 5 expands and increases in volume. In this process, since the airbag 5 is restricted by the flexible pull strip 7 and cannot continue to expand outward ("outward" means pointing in the direction away from the human skin), the pushing force applied by the airbag 5 to the electrode sheet 4 gradually increases, and the pressure data detected by the pressure sensor 1 begins to rise. After the pressure data rises to the original value ("original value" refers to the initial pressure value detected by the pressure sensor 1 when the electrode sheet 4 is attached to the human skin), the controller 3 controls the air pump 14 to stop working and no longer inflate the airbag 5, thereby reinforcing the electrode sheet 4 and preventing the electrode sheet 4 from loosening and falling off.

[0042] During use, if the pressure sensor 1 detects that the pressure data suddenly decreases significantly, the controller 3 controls the alarm 2 to work, and the alarm 2 sends out a sound signal and a light signal to warn the user or medical staff that the electrode sheet 4 is loose or falls off. At this time, problems such as the annular patch 6 falling off or the airbag 5 leaking may also occur, which need to be dealt with in time.

[0043] When the electrode sheet 4 needs to be removed, the first sealing member 17 on the exhaust pipe 16 is removed, so that the exhaust pipe 16 is connected to the outside atmosphere. In this way, the air in the airbag 5 is discharged through the inflation hose 13 and the exhaust pipe 16, and the volume of the airbag 5 is reduced and restored. Then, the annular patch 6 is removed from the human skin, and the removal of the monitoring device is completed. Finally, the electrode sheet 4 is removed from the human skin.

[0044] In addition, after the first adhesive film 8 has been used for a period of time, its viscosity decreases and it cannot maintain good adhesion with human skin. At this time, the user or medical staff separates the Velcro hook surface 9 from the Velcro fleece surface 10, thereby removing the first adhesive film 8 from the annular sticker 6, and then replaces it with a new first adhesive film 8 (with the Velcro fleece surface 10).

[0045] In summary, in this embodiment, the pressure sensor 1 is used to monitor the pressure applied by the electrode sheet 4 to the human skin. When the pressure decreases, the air pump 14 automatically inflates the airbag 5, so that the airbag 5 applies a pushing force to the electrode sheet 4, thereby realizing automatic reinforcement of the electrode sheet 4. In this way, this embodiment realizes the reinforcement of the electrode sheet 4 while monitoring the loosening of the electrode sheet 4, ensuring the treatment effect and reducing the workload of medical staff. In addition, the monitoring device in this embodiment can be reused, is not a disposable product, and is economical and practical.

[0046] Embodiment 2

[0047] The difference between this embodiment and the first embodiment is that: Figure 5 and Figure 6 As shown, the monitoring device in this embodiment also includes a negative pressure reinforcement component, which includes a plurality of suction cups 18, and the number of suction cups 18 is the same as the number of edge ears 11; in addition, no release paper layer is provided on the second adhesive film 12, and the second adhesive film 12 is adhered to the suction cups 18, so that the edge ears 11 and the suction cups 18 are relatively fixed.

[0048] The top of the suction cup 18 is connected to an air extraction hose 19, and the end of the air extraction hose 19 away from the suction cup 18 is connected to an air extraction pump 20. A second one-way valve 21 for guiding air out of the suction cup 18 is installed on the air extraction hose 19, and a return air pipe 22 is connected to the air extraction hose 19. The connection point between the return air pipe 22 and the air extraction hose 19 is located between the second one-way valve 21 and the suction cup 18. The free end of the return air pipe 22 is provided with a second sealing member 23 for sealing the free end of the return air pipe 22; in this embodiment, the second sealing member 23 is threadedly connected to the free end of the return air pipe 22.

[0049] The edge ear 11 and the second adhesive film 12 are provided with through holes for the exhaust hose 19 to pass through. The end of the exhaust hose 19 close to the suction cup 18 is connected to a baffle 24, which is located on the side of the edge ear 11 away from the suction cup 18, so as to prevent the edge ear 11 from falling off the suction cup 18 and moving away from the suction cup 18.

[0050] In the present embodiment, when in use, after the annular patch 6 is pasted on the human skin by the first adhesive film 8, the flared end (bottom) of the sucker 18 is in close contact with the human skin, and a confined space is formed inside the sucker 18. Then, the air pump 20 is started, and the air in the sucker 18 (the air in the confined space) is extracted through the air extraction hose 19, and a negative pressure is formed in the sucker 18, thereby fixing the edge ear 11. In this way, in the present embodiment, the first adhesive film 8 is used to fix the annular patch 6, and the negative pressure reinforcement assembly is used to fix the edge ear 11, thereby improving the firmness between the monitoring device and the human skin, and then better reinforcing the electrode sheet 4, avoiding the electrode sheet 4 from loosening and falling off. And, because the annular patch 6 and the edge ear 11 are soft, therefore, in the present embodiment, each sucker 18 moves independently, and does not affect each other, so that the sucker 18 adapts to the human body curve and fits closely with the human skin, and it is easier to form a confined space.

[0051] In addition, when removing the monitoring device, first remove the second sealing member 23 on the air return pipe 22, so that the air return pipe 22 is connected to the outside atmosphere, and the outside air flows into the suction cup 18 through the air return pipe 22 and the air suction hose 19, and the negative pressure in the suction cup 18 disappears, so that the user can easily remove the suction cup 18, avoiding the patient from feeling discomfort or pain. Then, remove the first sealing member 17 on the exhaust pipe 16, and remove it according to the operation described in the first embodiment.
