A chest valve including: a housing including an inlet configured to connect to a chest tube, an outlet and a fluid passage from the inlet to the outlet; and a one-way valve within the housing and included in the flow passage, wherein the one-way valve includes: (i) a first tubular strip wherein having an internal air passage and a first layer defining the air passage, wherein the first layer has a first thickness and the internal air passage of the first tubular strip is included in fluid passage of the housing; and (ii) a second tubular strip wherein having a second layer with a second thickness with a second thickness greater than the first thickness, wherein an outer surface of the second tubular strip is adjacent and overlaps an outer surface of the first tubular strip.

A chest drainage system includes a collection device and a fluid pathway configured to extend from the collection device to a patient. A pressure source is configured to selectively provide sub-atmospheric pressure to the fluid pathway. The system is configured to introduce sub-atmospheric pressure from the pressure source at a substantially constant target pressure and at a dynamic pressure that varies from the target pressure. A method is also disclosed for draining a pleural cavity of a patient. The method involves applying dynamic pressure to the pleural cavity of a patient by changing sub-atmospheric pressure applied to the patient such that the patient's pleura moves without any or limited patient activity, thus facilitating removal of loculated fluid from the pleural cavity. The method may involve the use of the chest drain system.

A medical device for use with an associated tube inserted into an incision formed in skin or tissue of a patient includes a dressing including an opening sized to receive and allow movement of the associated tube. A valve is operatively connected with the opening of the dressing and includes a main body; and an opening formed in a portion of the main body. The opening is sized and dimensioned to accommodate the surgical tube.

A drainage device for removing fluid from a body cavity of a patient is provided. The device comprises a drainage tube, and a pressure sensing means. The drainage tube is connectable to a pump unit, which unit is configured to apply a suction pressure to the fluid in the body cavity, and the pressure sensing means is configured to detect when the applied suction pressure is at or above a predetermined threshold level.

The present disclosure provides apparatus and method for treating tension pneumothorax by using a rapid deployment chest port. The rapid deployment chest port can penetrate a patient's body to access a distressed pleural space. The rapid deployment chest port may create an airtight seal between the inside and outside of the patient's body and, when expanded, allow air or fluid to flow in one direction from inside the body to outside the body.

A fluid-management system for selectively draining fluid from a body cavity includes a valve assembly and a tube for carrying fluid from a body cavity of a person to the valve assembly. The valve assembly is configured to be positioned external to the person's body and comprises (i) an inlet, (ii) an outlet, (iii) one or more one-way valves positioned between the inlet and outlet that are each configured to open and close based on fluctuations in pressure between the person's body cavity and the one-way valve, and (iv) an adjustable outlet lock configured to selectively prevent fluid movement through the outlet.

A chest valve including: a housing including an inlet configured to connect to a chest tube, an outlet and a fluid passage from the inlet to the outlet; and a one-way valve within the housing and included in the flow passage, wherein the one-way valve includes: (i) a first tubular strip wherein having an internal air passage and a first layer defining the air passage, wherein the first layer has a first thickness and the internal air passage of the first tubular strip is included in fluid passage of the housing; and (ii) a second tubular strip wherein having a second layer with a second thickness with a second thickness greater than the first thickness, wherein an outer surface of the second tubular strip is adjacent and overlaps an outer surface of the first tubular strip.

A device for releasably and adjustably securing a medical tube includes a receiver and a tail, which may be used for thoracostomy. The receiver has a receiver aperture and receiver teeth. The tail has center holes along a central axis of the device. Raised tail teeth are formed on the tail between the central axis and the tail sides. The tail teeth are arranged to engage the receiver teeth when an end of the tail is fed through the receiver aperture to form a tail loop. The receiver teeth define receiver teeth apertures that are smaller than the receiver aperture. The tail loop is adjustable to tighten around the medical tube.

An automatic pump-based fluid management system, as described herein, comprises an intercostal pump that is, generally, a resiliently flexible bulb having an inlet and an outlet. The inlet is attached to a first tube that extends from the intercostal pump to a first area of a patient's body, for example, the patient's pleural cavity. The outlet is connected to a second tube that extends from the intercostal pump to a second area of a patient's body, for example, the patient's peritoneal cavity. In use, the intercostal pump is placed between a first rib and a second rib in a patient. The intercostal pump operates by being successively compressed and decompressed between the first and second ribs as the patient breaths.

A fluid-management system for selectively draining fluid from a body cavity includes a valve assembly and a tube for carrying fluid from a body cavity of a person to the valve assembly. The valve assembly is configured to be positioned external to the person's body and comprises (i) an inlet, (ii) an outlet, (iii) a pumping chamber between the inlet and outlet and configured to be compressed and decompressed to pump fluid, (iv) a first one-way valve positioned on a first side of the pumping chamber, (v) a second one-way valve positioned on a second side of the pumping chamber, and (vi) an adjustable inlet lock configured to selectively prevent fluid movement through the inlet, and wherein the tube is configured to extend from the inlet of the valve assembly to the person's body cavity.
