Abstract

The invention discloses a multifunctional catheter. The part, contacting the urethra of a human body, of catheter forms a urethral section; the rest part out of the human body is an external section; the urethral section is provided with a metal coil; at least two miniature vibration motors are connected with the metal coil in parallel; the miniature vibration motors are fixedly arranged in the catheter wall of the urethral section and is connected with an external control circuit and a power supply through the metal coil; a permanent magnet is also arranged in the catheter wall of the urethral section ; and a magnetic field can be generated in the human body by arranging the permanent magnet in the catheter wall of the urethral section so as to improve microcirculation of the human body and accelerate absorption of inflammation exudates. The miniature vibration motor can massage the urethra, and has the effects of relieving postoperative pain and expanding the urethra. The catheter is favorable for preventing and curing adhesion and infection, promoting early repair, dispersing swelling and relieving pains. The multifunctional catheter can effectively relieve pain and complication of ordinary patients caused by implanting the catheter, and is convenient for urethral postoperative recovery of the patients.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a multifunctional urinary catheter. Background technique [0002] A urinary catheter is a tube made of rubber, silicone or plastic that can be inserted into the bladder through the urethra to drain urine. It is a common medical device in medicine. Experiments have proved that the magnetic field can change blood rheology, reduce blood viscosity, reduce the aggregation between red blood cells, and increase the activity of superoxide dismutase. After the magnetic field acts on the human body, one of the main changes caused in the body is the effect on blood circulation. In particular, it improves microcirculation, enhances the material exchange capacity of tissue cells, improves cell viability, promotes local blood circulation, accelerates the absorption of inflammatory exudate, and is beneficial for reducing swelling and analgesia. Existing magnetic therapy devices all act on the ...
