Description

One-way conduction valve, application and pressure relief valve Technical Field The invention belongs to the technical field of medical appliances, and particularly relates to a one-way conduction valve, application and a pressure relief valve. Background The existing drainage tube (such as catheter) valve component is complex in structure, some valves (such as a male catheter with a magnetic switch in China patent, application number 202110581173.7) are driven by electromagnets, the driving device needs huge power supply and can be realized in a superconducting environment, miniaturization cannot be realized in reality, a patient cannot carry about, and some valves need to be continuously excited by a magnet, so that attractive force between an external driving magnet and the valve component leads to tissue crush injury when the valve component is applied to a human body. When a patient suffers from diseases such as lower urinary tract obstruction diseases or neurogenic bladder, the patient cannot control urination autonomously, and the urinary catheter is required to assist in controlling urination. The catheter needs to be provided with a one-way conduction valve, and is opened when urination is needed and closed when urination is not needed. Thus, there is a need for a one-way conduction valve that is safe and convenient for the patient to use. In addition, in the practical application of the prior art, the valve core of the catheter lacks self-cleaning function, so that the phenomenon of valve liquid leakage is caused by salting out of urine crystals in the valve body, and the axial displacement of the catheter is caused when the closed annular driving device is in place or is separated. Disclosure of Invention The invention aims to provide a one-way conduction valve, which can be opened and closed by a driving body which is detachable outside a pipe body, and the driving body can be used in place or separated along the radial direction of the pipe body. The technical scheme provided by the invention is as follows: a one-way conduction valve comprising: A tube body; a first fixing ring fixed on the inner wall of the pipe body; The second fixing ring is fixed on the inner wall of the pipe body and is arranged at intervals with the first fixing ring; A movable valve core arranged in the pipe body and positioned between the first fixed ring and the second fixed ring; a driving body which is positioned outside the tube body and is an arc-shaped magnet with an opening, or The driving body comprises two semicircular magnets which are oppositely arranged to form a circle, wherein one ends of the two semicircular magnets are connected through a hinge, and the other ends of the two semicircular magnets can be connected or separated; Under the magnetic drive of the driving body, the movable valve core can be combined with the first fixed ring to stop the circulation of the pipe body or combined with the second fixed ring to start the circulation of the pipe body. Preferably, a blocking structure is arranged at one end of the movable valve core, which faces the first fixing ring, and the blocking structure can block the inner cavity of the first fixing ring. Preferably, the moving spool further includes: a guide ring provided inside the pipe body and movable along the pipe body; One end of the bracket is fixedly connected to the guide ring, and the other end of the bracket is fixedly connected with the plugging structure; Wherein, have the space that fluid passed through between guide ring and the support.
