Problems solved by technology

Existing chest drainage methods usually use manual extrusion of the drainage tube to generate a pressure difference to drain the gas and liquid out of the chest cavity. This method is difficult to control a reasonable pressure and the effect is poor
There are also some cardiothoracic drainage devices, although the gas and liquid are discharged from the body in the form of negative pressure machine extraction, but the pressure range is difficult to adjust

Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific examples, but is not limited thereto.

[0030] Such as Figure 1 to Figure 7 As shown, the disposable dry-sealed valve chest drainage device of this example mainly includes a main housing 1, a panel 2, a drainage tube interface 3, a negative pressure machine interface 4, a negative pressure adjustment assembly 5, a support 8, a vent Pressure port 11, water injection port 12, air leakage indicator 15, anti-backflow pipe 16, one-way valve 17, plunger 18 and multiple cavities and other components;

[0031] The main housing 1 is mainly used for installing various functional components, and includes a plurality of cavities, mainly including cavities A~H (19~26), and these cavities cooperate with each functional component to form a plurality of functional containers. The panel 2 is installed in cooperation with the main casing 1 to form a closed multi-cavity structure.

[0032] Such as Figu...

Abstract

The invention discloses a disposable dry sealing valve type chest drainage device. The device comprises a main shell, a panel, a drainage pipe interface, a negative pressure machine interface, a negative pressure adjusting component, a support, a pressure relief opening, an air leakage displayer, an anti-backflow pipe, a one-way valve, a plunger, multiple cavities and the like. Accordingly, by means of the negative pressure range of a novel variable crosse section area adjusting device, negative pressure values are adjusted conveniently through a sliding plate, and under the action of the negative pressure machine, the negative pressure pumping capacity of the proper pressure range is provided; by means of the multiple-cavity structure, a U-shaped pipe structure is built, and the safe sealing function is generated by means of water or other liquid; various pressure display and protection devices are arranged, and the chest pressure safety is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable dry-seal valve chest drainage device. Background technique [0002] During cardiothoracic surgery, it is usually necessary to expel the gas and liquid in the chest cavity in time, and at the same time, it is necessary to control the pressure of the chest cavity in a reasonable range to ensure the safety of the patient. The existing pleural cavity drainage method usually adopts manual squeezing of the drainage tube to generate a pressure difference to discharge the gas and liquid out of the chest cavity. This method is difficult to control a reasonable pressure and the effect is poor. There are also some cardiothoracic drainage devices, although the gas and liquid are discharged from the body in the form of negative pressure machine extraction, but its pressure range is difficult to adjust. The air and fluid in the thoracic cavity need to be removed in time, and at t...
