Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a conductive block, a negative pressure adsorption bowl and an electrical stimulation therapeutic apparatus. Background Art

[0002] In the field of medical equipment, electrical stimulation therapy device is a commonly used medical device that uses electrical stimulation to treat various diseases, such as muscular dystrophy, nerve damage, etc.

[0003] When the electrical stimulation therapy device is in use, negative pressure gas is used to adsorb the wood cotton and the adsorption bowl to various parts of the human body, and the wet wood pulp cotton serves as a conductive medium, which transmits the medium frequency current emitted from the electrical stimulation therapy device to the user's affected area to achieve the electrotherapy effect.

[0004] It should be noted that wood pulp cotton itself is a material made of wood cellulose, has good water absorption and is a non-conductor, but it can conduct electricity when it is in a wet state.

[0005] It should be pointed out that the advantage of this technology is that wood pulp cotton itself has good water absorption and can effectively conduct current. However, the defects of the existing technology are as follows:

[0006] 1) When wood pulp cotton is wet treated, its humidity is difficult to control, which makes it difficult to control the consistency and stability of conductivity;

[0007] 2) During long-term use, wood pulp cotton is prone to breeding bacteria, which may lead to problems such as bacterial infection;

[0008] 3) The wet wood pulp cotton is easy to drop debris, which may block the pores, causing the adsorption pressure to decrease or even disappear, affecting the life of the equipment and the treatment effect;

[0009] 4) In addition, the wet wood pulp cotton directly contacts the human body surface when used, which will cause discomfort to the user. Although there is a solution to heat the wood pulp cotton by setting an additional heating module at the end that contacts the human body surface to solve the problem of physical discomfort, it should be pointed out that this solution will increase the manufacturing cost and use cost of the equipment. At the same time, the wood pulp cotton will be squeezed by the negative pressure gas during the treatment process, and the water will be recycled through the trachea for wastewater treatment, which will bring new technical problems, that is, it is necessary to design a special collection device, which increases the equipment cost.

[0010] Based on this, it is expected to obtain a new electrical stimulation therapeutic device, which can solve the inconvenience caused by the current use of wood pulp cotton while taking into account the manufacturing and use costs, and the use process can not affect the treatment effect. Summary of the invention

[0011] In view of the above-mentioned deficiencies of the conductive block of the current electrical stimulation therapeutic device, the present invention provides a conductive block, a negative pressure adsorption bowl and an electrical stimulation therapeutic device. The technical solution of the present invention can ensure the consistency of conductivity during use, avoid bacterial growth, reduce debris clogging, and improve the treatment effect.

[0012] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0013] The present invention proposes a conductive block, which includes an intermediate layer and a coating layer, wherein the intermediate layer is a hollow porous structure of wood pulp cotton, and its material is wood pulp cotton; the coating layer is fully or partially coated on the outer surface of the intermediate layer.

[0014] Preferably, the covering layer includes a first covering layer and a second covering layer, the first covering layer completely or partially covers the first outer surface of the intermediate layer, the second covering layer completely or partially covers the second outer surface of the intermediate layer, and the first plane where the first outer surface is located is skewed from the second plane where the second outer surface is located.

[0015] Preferably, the first plane is parallel to the second plane.

[0016] Preferably, the first covering layer and the second covering layer are connected by suturing.

[0017] Preferably, the covering layer covers the intermediate layer by sewing.

[0018] Preferably, the coating layer is made of silver fiber cloth.

[0019] It should be noted that in the technical solution described in the present invention, the silver fiber fabric is an existing material. It is a product that permanently combines pure silver on the fiber surface. This fabric structure allows the silver fiber to not only maintain the properties of the original textile, but also have all the characteristics of silver, with good antibacterial properties, extremely strong conductivity, and radiation protection.

[0020] Of course, it is conceivable that the covering material may also be made of other cloths of similar material to the silver fiber cloth, preferably a skin-friendly cloth.

[0021] On the other hand, the present invention provides a negative pressure adsorption bowl, in which the above-mentioned conductive block is arranged.

[0022] Preferably, the negative pressure adsorption bowl further comprises: a conductive metal sheet, which is bonded to the conductive block.

[0023] In addition, in some preferred embodiments, in order to increase the conductive effect, the contact surface between the negative pressure adsorption bowl and the conductive block can be made of a conductive composite material. It should be noted that in the technical solution described in the present invention, the conductive composite material is an existing material, which refers to a composite conductive polymer material formed by a certain composite method of polymers and various conductive substances, such as conductive plastics or conductive rubber.

[0024] On the other hand, the present invention provides an electrical stimulation therapeutic device, which includes the above-mentioned negative pressure adsorption bowl.

[0025] Preferably, the electrical stimulation therapeutic apparatus further comprises:

[0026] A negative pressure pipeline is connected to the negative pressure adsorption bowl pipeline.

[0027] Preferably, a conductive metal sheet is provided in the negative pressure adsorption bowl, one end of the conductive metal sheet is arranged close to the negative pressure pipeline to be electrically connected to the conductive wire in the negative pressure pipeline, and the other end is connected to the conductive block.

[0028] Compared with the prior art, the present invention has at least one of the following advantages and beneficial effects:

[0029] First, the coating layer is provided to cover the intermediate layer to improve the consistency of the conduction. In particular, in some preferred technical solutions, by sewing silver fiber cloth on the surface of wood pulp cotton as a conductive medium, the consistency of the conduction can be effectively improved, especially because the silver fiber cloth has good conductivity and is not affected by the external environment, so the conductivity of the electrical stimulation therapeutic device can be guaranteed to be stable, and thus the effect of the electrical stimulation therapy can be improved, and the treatment effect and recovery speed of the patient can be improved.

[0030] Second, the coating layer is provided to cover the middle layer to prevent bacteria from growing. Since the coating layer uses a cloth with a sterilizing function such as silver fiber cloth, it can effectively prevent the middle layer such as wood pulp cotton from growing bacteria during use, reducing infection and other problems, which is of great significance for patients who use the electrical stimulation therapy device for a long time.

[0031] Third, the coating layer is provided to cover the middle layer to reduce the blockage of debris in the middle layer. Since the coating layer covers the debris in the middle layer, the debris can be prevented from blocking the pores, thus protecting the use of the device, extending the service life, and reducing the cost of maintenance and replacement.

[0042] Example 1

[0043] Figure 1 It is a schematic structural diagram of a conductive block according to an embodiment of the present invention. Figure 2 It is a schematic diagram of the interlayer structure of the conductive block in one embodiment of the conductive block described in the present invention.

[0044] like Figure 1 As shown, and when necessary, refer to Figure 2 In this embodiment, the conductive block 1 includes an intermediate layer 11 (the intermediate layer 11 can be seen in Figure 2 ) and a covering layer 12, wherein the middle layer 11 is wood wool with a hollow porous structure, and the covering layer 12 is silver fiber cloth.

[0045] The covering layer 12 completely covers the outer surface of the middle layer 11 by sewing, which is machine sewing in this embodiment. A conductive sewing thread 13 is used during the machine sewing to ensure that the silver fiber fabric as the covering layer 12 and the wood pulp cotton as the middle layer 11 are tightly combined, thereby improving the conductive effect and the sterilization effect.

[0046] It should be pointed out that in some other embodiments, those skilled in the art may select the coating layer 12 to partially coat the outer surface of the intermediate layer 11 according to the specific circumstances of the embodiment.

[0047] In some other embodiments, in addition to sewing, other methods can be selected to cover the covering layer 12 on the outer surface of the middle layer, such as bonding or Velcro connection.

[0048] Depend on Figure 1It can be seen that the conductive block of this embodiment 1 uses silver fiber cloth as a conductive medium sewn on the surface of wood pulp cotton. By sewing the silver fiber cloth with the wood pulp cotton, the high conductivity and good bactericidal function of the silver fiber can be utilized, thereby solving the problems of poor conductive consistency, bacterial growth and debris clogging.

[0049] In some preferred embodiments, the silver fiber cloth can be selected to have high flexibility and durability to ensure its stability and reliability during long-term use. In addition, in order to increase the service life, it is also possible to consider maintaining and preserving the silver fiber cloth, such as cleaning and disinfecting, to prevent it from deteriorating or being damaged, thereby extending its service life.

[0050] In addition, by sewing silver fiber cloth on the surface of wood pulp cotton as a conductive medium, the consistency of conductivity can be effectively improved, and this method can effectively prevent the wood pulp cotton from breeding bacteria and reduce infection and other problems.

[0051] Furthermore, the silver fiber cloth coating can prevent the wood pulp cotton from falling into debris and clogging the pores, which can extend the service life of the electric stimulation therapy device and reduce the cost of maintenance and replacement.

[0053] The conductive block structure of the second embodiment is the same as that of the first embodiment, except that the cladding layer 12 includes a first cladding layer 121 and a second cladding layer 122. Figure 2 .

[0054] like Figure 2 As shown, the first coating layer 121 completely coats the first outer surface of the intermediate layer 11, and the second coating layer 122 completely coats the second outer surface of the intermediate layer. The first plane where the first outer surface is located is parallel to the second plane where the second outer surface is located.

[0055] It should be noted that, in some other embodiments, the first coating layer 121 and the second coating layer 122 are not only Figure 2 In addition to the upper and lower surface coverings of the intermediate layer shown, the intermediate layer 11 may also be completely or partially covered by a first covering layer 121 covering the upper surface of the intermediate layer and a second covering layer 122 covering the side surface of the intermediate layer.

[0056] In some preferred embodiments, the first coating layer 121 may be provided with an electrode adhesive sheet so that the conductive block can be better adhered to the electrode during use.

[0057] The second coating layer 122 may be provided with a skin adhesive patch to help ensure stable contact between the electrical stimulation therapeutic device and the skin of the subject, reduce displacement during treatment, and reduce the need for adjustment during treatment.

[0058] Of course, those skilled in the art can set it according to the specific conditions of the implementation, such as the requirements of the pasting position: the first covering layer 121 is used to paste the electrode sheet, and the second covering layer 122 is used to set the skin pasting sheet.

[0059] In addition, in some preferred embodiments, the skin adhesive patch and / or the electrode adhesive patch may be provided with release paper to help protect the adhesive surface, which not only facilitates the cleaning and replacement of the adhesive patch, but also helps prevent cross infection and improves the hygienic standards of treatment.

[0060] Example 3

[0061] In this embodiment, a negative pressure adsorption bowl is disclosed. A conductive block is provided in the negative pressure adsorption bowl. The conductive block is the conductive block 1 of Embodiment 1.

[0062] Of course, it is conceivable that Example 3 may also adopt the conductive blocks of Example 2, which may be freely combined.

[0063] In some other embodiments, the conductive block 1 can be fixed in the negative pressure adsorption bowl by means of a locking arrangement. In order to improve the conductive effect, the contact surface between the negative pressure adsorption bowl and the conductive block can be made of a conductive composite material, for example, conductive rubber.

[0064] Example 4

[0065] In this embodiment, an electrical stimulation therapeutic device is disclosed, wherein the electrical stimulation therapeutic device is as follows: Figure 3 and Figure 4 shown.

[0068] like Figure 3 As shown, and when necessary, refer to Figure 4 The electrical stimulation therapeutic apparatus includes a negative pressure adsorption bowl 3 and a negative pressure pipeline 2, and the negative pressure pipeline 2 is connected to the negative pressure adsorption bowl 3.

[0069] Among them, the structure of the negative pressure pipeline 2 can adopt the existing structure, for example, one end of the pipeline is connected to the negative pressure adsorption bowl 3, and the other end is connected to the pump to generate negative pressure gas.

[0070] Further references Figure 3 and Figure 4It can be seen that a conductive metal sheet 4 is provided in the negative pressure adsorption bowl 3 , one end of the conductive metal sheet 4 is arranged close to the negative pressure pipeline 2 to be electrically connected to the conductive wire in the negative pressure pipeline 2 , and the other end is connected to the conductive block 1 .

[0071] When in use, the body surface contact surface 5 of the electrical stimulation therapeutic device is in close contact with the body surface of the patient. Since the surface is actually the coating layer 12 of the conductive block 1, and the coating layer 12 is made of a skin-friendly and soft material, it will not cause discomfort to the patient.

[0072] The negative pressure adsorption bowl 3 connected to the negative pressure pipeline 2, wherein the negative pressure gas and the conductive wire are connected to the negative pressure adsorption bowl 3, and the inside of the negative pressure adsorption bowl 3 is connected to the conductive metal sheet 4. The conductive metal sheet 4 and the conductive block 1 of the electric stimulation therapy device are installed inside the negative pressure adsorption bowl, and the negative pressure adsorption bowl 3 is pumped into a negative pressure state by the negative pressure gas and the conductive wire, so that the body surface contact surface of the negative pressure adsorption bowl is fixed on the skin of the subject.
