Liquid collection device of negative-pressure wound care system and combination thereof

Abstract

The invention relates to a liquid collection device of a negative-pressure wound care system, which comprises a soft liquid collection bag and a liquid absorption material, wherein the liquid collection bag is connected with wound dressing through an inlet connection assembly, and is connected with a sensor through a sensing connection assembly. The design of the soft liquid collection bag greatly reduces the volume occupied by the liquid collection device; and the design of the liquid absorption material and a breathable diaphragm of the liquid collection bag achieve the effect of fast air-water separation. Besides, multiple liquid collection devices can be connected in series to form a combination so as to reduce the replacement frequency for the user, thereby providing convenience for long-time use.

Description

technical field [0001] The invention relates to a liquid collection device of a negative pressure wound care system, which is a liquid collection device used in the negative pressure wound care system to collect waste liquid. Background technique [0002] Negative Pressure Wound Therapy (Negative Pressure Wound Therapy) mainly uses sealing patches, soft suction cups, or biocompatible porous materials to attach to the wound, and connects a vacuum pump to form a negative pressure environment in the wound to extract wound pus and infectious substances, and attract healthy tissue fluid to maintain a moist treatment environment, and promote the surrounding blood microcirculation to achieve the effect of accelerating wound healing. [0003] The negative pressure wound care system of the prior art is to connect the vacuum pump to the back end of the liquid collection device of the prior art, and the vacuum pump forms a negative pressure environment in the wound and the liquid colle...

[0003] The negative pressure wound care system of the prior art is to connect the vacuum pump to the back end of the liquid collection device of the prior art, and the vacuum pump forms a negative pressure environment in the wound and the liquid collection device through the liquid collection device of the prior art, and utilizes the existing The liquid collection device of the prior art is used to collect the waste liquid. Since the liquid collection device of the prior art needs to form a negative pressure environment, it is necessary to use a hard container, such as a cup body, a shell, etc., to allow the interior to be under negative pressure without being affected by ambient gas. Extruded and deformed, however, the hard container occupies a certain volume and size, which is not only unfavorable for carrying and storage, but also the container filled with waste liquid must be treated in the same way as medical waste, which also increases the volume of medical waste
