Description

Electric field generating device

Technical Field

The present utility model relates to an electric field generating device capable of noninvasively discharging a disease-related effusion of a living body, uses thereof, and a method for discharging a disease-related effusion using the same.

Background

In daily life, some disease sites are subjected to effusion due to inflammation, hemorrhage, and the like.

For example, due to improper movement, diseases such as joint edema (arthromeningitis) and the like accompanied by inflammation, edema, nerve ending pain and the like are often caused. Synovitis is mainly caused by obstruction of microcirculation, and when pain information is transmitted to cerebral cortex, the synovitis can secrete more synovial fluid to lubricate and nourish affected parts, and effusion is gradually formed in joint gaps. When the effusion in the joint space is increased and the output of the secretion synovial fluid is greater than that of the secretion synovial fluid, swelling and pain are easily caused, and even the joint is caused to be difficult to rotate. The principle of joint edema (joint synovitis) is to regulate and dredge microcirculation, and the joint edema can be recovered as long as the microcirculation is thoroughly smooth.

At present, various osteoarthropathy effusions are treated mainly, when the effusion in the joint space is increased and movement or movement is difficult, the effusion is temporarily extracted, and when joint core substances are absent, damaged articular cartilage and synovium are repaired by supplementing substances, the regeneration capacity of the cartilage and the synovium is promoted, and the joint synovium is induced.

Clinically, 1: the arthroscope diagnosis and treatment system can effectively treat joint diseases such as rheumatism, rheumatoid arthritis, osteoarthritis, gouty arthritis and the like through joint washing, specific traditional Chinese medicines and the like; 2: the magnetic therapy combination system of traditional Chinese medicine. The far infrared magnetic therapy cataplasm is adopted, the blood circulation is accelerated by utilizing the far infrared warm effect, the microcirculation condition of bone tissues is improved, the metabolism is enhanced, and the unbalance condition of the bone tissue system is changed; 3: neodymium iron boron is adopted as a main material, and a magnetic field is emitted to directly treat a deep patient part, so that full, rapid and comprehensive penetration of the effect is ensured; 4: oral administration for a long time such as anti-inflammation, pain relieving, antirheumatic etc.; 5: injecting a closed needle to directly inject hormone, anesthesia and therapeutic substances into the joint, and locally relieving; 6: in severe cases, the physician orders withdraw the effusion and inject sodium hyaluronate (or artificial lubricant) into the joint. 7: acupuncture, massage, arthroscopic surgery, etc.

For another example, the reason why the joint effusion is increased due to the excessive joint effusion in the hip joint can be simply understood as local aseptic inflammation, or infectious inflammation, the former is often found in some diseases such as synovitis and osteoarthritis of the hip joint, and the latter is often found in intra-articular infections complicated with systemic infection or intra-articular infections complicated with trauma of the joint. Excessive fluid accumulation within the hip joint can lead to instability and localized pain in the hip joint and problems with the blood supply to the femoral head. And may be followed by necrosis of the femoral head.

Aiming at different effusion amounts of hip joint effusion, different treatment measures are needed clinically, if the effusion amounts are relatively small, conservative treatment can be used in early stage, such as the requirement of bedridden braking of a patient, and the warming of hip joint parts is noted, and some medicines for diminishing inflammation, detumescence and relieving pain are assisted for treatment. Local hip joint penetration can also be performed in a short period of time to aspirate joint fluid, but care must be taken to perform aseptic procedures to prevent infection. If there is a significant amount of hip effusion, arthroscopic surgery of the joint may be required to address the problem.

In addition, in the brain, hydrocephalus or hydrocephalus (disease site hydrocephalus) is caused by the fact that cerebral hemorrhage is followed by the influence of the obstruction of the cerebrospinal fluid circulation path, and hydrocephalus is caused by accumulation in the ventricle due to the difficulty in recovering cerebrospinal fluid. The causes of the disease are classified into one: congenital hydrocephalus: the common ones are: 1. cerebral aqueduct deformity; 2. subconaeus tonsillar hernia deformity; 3. Congenital closure of the median and side holes of the fourth ventricle; 4. a significant portion of congenital hydrocephalus can be caused by infant posterior fossa tumors; 5. other congenital diseases such as achondroplasia, craniocerebral interface deformity, spina bifida, mole-like hamartoma, dandy-Walker syndrome, callus defects such as cerebral palsy, etc. can be accompanied by hydrocephalus; and II: the acquired hydrocephalus has the main causes: 1. bacterial, fungal, viral infections occurring in the mother or after birth in infants infected intracranially, resulting in hydrocephalus; 2. subarachnoid hemorrhage caused by various reasons of subarachnoid hemorrhage refers to that liquid in blood plasma seeps into subarachnoid cavity to cause intracranial pressure increase due to cerebral vascular embolism or infection and other reasons, and the intracranial pressure increase is quite dangerous, so that the brain is pressed, and brainstem is pressed outwards, thereby stopping respiratory heartbeat; 3. hydrocephalus caused by infection and hemorrhage is usually a communicating hydrocephalus.

The hazards that hydrocephalus can cause include (1) urinary disorders, frequent, incontinent or difficult urination, sometimes occurring only in the late stages. (2) The intelligent disorder can only have slight hypomnesis and computational hypofunction, and is usually accompanied by dullness, apathy, mutism and the like. The heavy person may be dementia. Few may be agitation, irritability, crying and smiling, hallucinations, delirium, etc. (3) Movement disorder, which usually begins gradually after the occurrence of mental symptoms, has difficulty in starting and slow and unstable walking. Muscle tone and tendon reflex are often increased, with positive reflex. Sometimes manifested as hemiparalysis.

In clinical common practice, the way of dewatering and lowering the craniocerebral pressure or the way of needing operation treatment, the drainage of the ventricle is to perform the operation to drain the hydrocephalus in the ventricle and then treat the hydrocephalus; or thrombolytic drugs are generally administered, or cerebral effusion is withdrawn through lumbar puncture, or directly from the cranium.
