Description
Technical field
This utility model relates to ball valve, is a kind of thoracic cavity water seal drainage system ball valve.
Background technology
Chest drainage normally lean on patient each time during breath cycle naturally the intrapleural pressure of formation realize.Thoracic duction instrument is a kind of pneumothorax, hydrothorax that a variety of causes causes that be mainly used in, and need carry out closed drainage patient's medical product after the operation.Like the patent No. ZL200620033725.1 that discloses in the Chinese patent document; October 31 2007 Granted publication day; Utility model title " check valve water seal drainage system "; The check valve loam cake of this drainage system is connected with the check valve lower cover, and ball float is placed in check valve loam cake and the cavity that the check valve lower cover is connected; The check valve loam cake is provided with a circular narrow orifice, and the check valve lower cover is provided with a top ridge and a liquid pass hole.This type of check valve or title ball valve, the spool of ball valve is spheroid, and it is mainly used in cut-out, distributes and change the flow direction of medium.But the set position of said structure is unreasonable, clottage when causing behind the operation on heart drain easily, and the drainage system structural design is not good enough.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to this area a kind of thoracic cavity water seal drainage system ball valve to be provided, and makes it solve existing like product structure and the not good enough technical problem of drainage system structural design that is suitable for.Its objective is and realize through following technical scheme.
A kind of thoracic cavity water seal drainage system ball valve, the main body of this ball valve is backflow preventer or malleation relief valve, it is arranged at the aperture of drainage system; Said ball valve comprises valve seat, spool, valve pocket, and valve pocket and valve seat interference fit constitute valve body, and the through hole in valve pocket and the valve seat communicates, and is provided with spool in the valve body; The ball valve Assembling Production of said structure is convenient.Its structural design main points are that said spool is spheroidal, and the spool stomidium mouth of valve pocket is provided with the valve opening muscle, curved of valve opening muscle, and the aperture of valve seat is provided with spacing muscle, and the fit end of valve pocket and valve seat is respectively equipped with seat pipe muscle and sleeve pipe muscle.Like this, the spool of ball valve is limited in the valve body through the valve opening muscle of valve pocket, the spacing muscle of valve seat, and makes the pipe fitting that connects this ball valve connect, be limited in this ball valve through the seat pipe muscle of valve pocket, the sleeve pipe muscle of valve seat.When spool moved to the spacing muscle end of valve seat by the fluid effect, this ball valve was an open mode, and fluid flows to valve seat by valve pocket; When spool moved to the valve opening muscle of valve pocket by the fluid effect, the arcwall face of the sphere of spool and valve opening muscle was conflicted, and this ball valve is a closed condition.
The valve seat of said backflow preventer and water sealing (sealing water) pipe fit, the valve pocket of this backflow preventer communicated with fluid collection chamber through communicating pipe.The effect of backflow preventer is to prevent that patient inhales and when cough be drawn back into fluid collection chamber with the liquid in the water seal chamber, so its requirements do not form sealing to gas, and the liquid formation resistance to refluxing.
The valve pocket of said malleation relief valve is connected with the pressure regulating cavity of drainage system.The malleation relief valve is as a kind of safety device, and the attraction mouth of drainage system is in case unexpected the obstruction still can discharge malleation to guarantee safety through it.
Said drainage system is provided with fluid collection chamber, water filling port, water seal chamber, water sealing (sealing water) pipe, pressure regulating cavity, surge pipe, and said water sealing (sealing water) pipe, water seal chamber, pressure regulating cavity, surge pipe communicate successively, and separate with fluid collection chamber, and water filling port is arranged at surge pipe; Fluid collection chamber is connected with drainage tube, and communicating pipe is connected with fluid collection chamber, water sealing (sealing water) pipe respectively, and the water seal chamber is provided with cock.Above-mentioned drainage system or title drainage bottle, this drainage bottle is three chamber type drainage bottles, and promptly the structure difference according to drainage bottle is divided into three chamber types or two chamber types, and two chamber type drainage bottles have reduced the pressure regulating cavity that supplies outside attraction usefulness.
The bottom of said drainage system is provided with runing rest, and the hangers of drainage system is provided with hook.Hook is used for the suspension of drainage system, and runing rest is used for stablizing drainage system.
The bottom of said drainage system is provided with the gap, and the fixed mount convex tendon of runing rest inserts the gap of drainage system.Thereby be convenient to fixing between drainage system and the runing rest.
This utility model and its drainage system reasonable in design that is suitable for, easy to use, safety is good; The drainage system scope that is suitable for is wide, and is applicable to the architecture advances of like product.
