The present invention is generally relating to a method for manufacturing a biomedical signal conductive membrane. The present invention particularly represents the method for manufacturing the biomedical signal conductive membrane that displays a particular gel membrane type that can prevents toxic monomer from generating.
A liquid conductive gel must be spread on a diagnostic region of subject in conventional ultrasonic diagnosis so as to make transducer probe of ultrasonic instrument moved smoothly to support the physician for detailed diagnosis. However, the liquid conductive gel will adhere to clothes or other region of subject through the movement of transducer probe therefore causing difficulty for cleaning. Besides, the liquid conductive gel is easily infected by bacteria to cause extra injury to the subjects, because the incomplete sterilization in the manufacturing process or impropriate storage. Accordingly, a newly conductive pad is developed. The newly conductive pad is produced by polymer composite, but the toxic monomer is generated during the producing process to contaminate the environment. Additionally, the human body might be injured by the toxic monomer released from the newly conductive pad. The newly conductive pad is thicker and merely adoptable to specific ultrasonic instrument, and the use of the newly conductive pad applied to the region of human is limited as well. For instance, the newly conductive pad is not able to adhere onto the joint or elbow smoothly. Therefore, the newly conductive pad can not be applied to the joint or elbow of human body.
The primary object of the present invention is to provide a method for manufacturing a biomedical signal conductive membrane. By the property modification of natural polymer material to prevent the toxic monomer generate in the manufactured process of the conductive pad.
The other object of the present invention is to provide a method for manufacturing a biomedical signal conductive membrane. A formed gel membrane has a smooth contact surface that not only prevents adherence from the gel membrane, but also apply to various regions of human body therefore increasing convenience and range of use.
A method for manufacturing a biomedical signal conductive membrane at least includes providing a natural polymer material; adding an acid solution for making the natural polymer material dissolved in the acid solution to form a viscous liquid mixture; performing a dry step for drying the viscous liquid mixture to form an initial stage of membrane, wherein the structure of natural polymer material within the initial stage of membrane is a straight chain; providing a cross-linking agent to perform a cross-linking step for transforming the initial stage of membrane into a gel membrane, wherein the structure of natural polymer material within the gel membrane is a cross-linked network; and performing a rinse step for removing the cross-linking agent and keeping a plurality of water molecules remaining within the cross-linked network of natural polymer material. The present invention adopt the natural polymer material to produce the gel membrane with cross-linking network, and the gel membrane does not generate toxic monomer that contaminates the environment and injures human body. In addition, the gel membrane can substitute for the liquid conductive gel and the conductive pad that use inconveniently, and avoids adhering to skin, transducer probe and bed sheet like the liquid conductive gel. The gel membrane can satisfy the requirement of the health care employees and subjects.
With reference to

Next, referring to step 14 of
After that, referring to step 15 of
The present invention adopt the natural polymer material 110 to produce the gel membrane 140 that is cross-linking network, therefore, the gel membrane 140 does not generate toxic monomer that contaminates the environment and injures human body. In addition, the gel membrane 140 does not cause cytotoxicity and skin disorders. The gel membrane 140 is substitute for the liquid conductive gel and the conductive pad that use inconveniently, and avoids adhering to skin, transducer probe and bed sheet like the liquid conductive gel. The gel membrane 140 can satisfy the requirement of the health care employees and subjects. Besides, the cross-linking network of the gel membrane 140 enables to keep the water molecules remaining in the gel membrane 140 so that the gel membrane 140 possesses a certain swelling ratio. The thickness range of the gel membrane 140 is 500 to 2000 μm so as to stick on the uneven joint or elbow of human body easily therefore forming a smooth medium and solving the problem of blind spot for diagnosis via lowering the overflow of the liquid conductive gel. Preferably, the gel membrane 140 is made to be in form of cling film and possesses functions of disposability and prevention of bacteria cross-infection in a sickroom.
While this invention has been particularly illustrated and described in detail with respect to the preferred embodiments thereof, it will be clearly understood by those skilled in the art that is not limited to the specific features shown and described and various modified and changed in form and details may be made without departing from the spirit and scope of this invention.
