Succus conducting device and conducting method thereof

Abstract

The invention is to design a body fluid flow diverter and a flow diverting method for the flow diverter. The flow diverter consists of a storage area capable of storing body fluid and a non-storage area, a body fluid flow diverting interface, control valve assembly components, a pressure regulating valve and other parts, wherein, the non-store area comprises micro-metering area and water seal stabilizing area assembly components, suction channel assembly components and body fluid diverting channel assembly components, etc. The body fluid flow diverting method of the invention is that first the body fluid is diverted into a micro-metering area; when the diverted body fluid reaches the upper limit of the volume of the micro-metering area or the medical staff think the body fluid needs to be diverted, the body fluid in the micro-metering area is immediately diverted into a storage area, so as to empty the body fluid in the micro-metering area; and then the body fluid continues to be diverted into the micro-metering area, which can help the medical staff to repeatedly make use of the high-precision characteristic of the micro-metering area to estimate the body fluid diverted within unit time, so as to precisely measure the body fluid diverted within a time period and reduce estimation error.

Description

technical field

[0001] The invention relates to a medical device, in particular to a body fluid drainage device and a drainage method thereof. Background technique

[0002] After chest trauma, thoracic surgery and cardiac surgery, in order to observe the gas and fluid in the thoracic or pericardial cavity, including blood, lymph, etc., it is necessary to insert a drainage tube into the thoracic cavity or pericardial cavity to drain the gas and fluid that may threaten the life of the patient. Fluid is drained out of the body.

[0003] The hourly drainage volume (that is, the total amount of fluid drained from the thoracic or pericardial cavity within a unit of time) is crucial after surgery or early after drainage tube placement. Combined with a variety of laboratory tests, and through the evaluation of the hourly drainage volume, the rate of bleeding in the chest cavity or pericardium can be determined, and then it can be determined whether it is necessary to re-open the ch...

Embodiment Construction

[0036] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same numbers will be used throughout the drawings to refer to the same or like parts. In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the description of the present invention may be selected by the applicant according to his or her judgment, and the detailed meanings thereof are set forth herein described in the relevant section of the description. Furthermore, it is required that the present invention be understood not only by the actual terms used, but also by the meaning implied by each term.

[0037] The body fluid drainage device of the present invention is roughly the same as the general traditional drainage device in terms of physical storage structure, and also separates two areas, namely the micro mete...
