In some examples, a medical aspiration system includes a flow switch configured to passively close to restrict aspiration of a body fluid from a body of a patient. In some examples, the flow switch includes a housing defining an internal cavity, and proximal and distal openings to the internal cavity, where the internal cavity is configured to receive the aspirated fluid from a catheter. The flow switch further includes a plug disposed within the internal cavity and configured to move proximally, in response to an above-threshold drag force from a fluid flow of the aspirated fluid within the internal cavity applied to a distal-facing surface of the plug, in order to close the proximal opening; and move distally to open the proximal opening in response to an absence of the fluid flow within the internal cavity.

A disposable wearable micro-flow continuous drug delivery system has an elastic drug storage cavity for extruding and storing liquid drug, wherein one end of the elastic drug storage cavity is communicated with a drug outlet pipe, wherein one end of the drug outlet pipe is communicated with a first micro-flow path and a second micro-flow path for shunting liquid drug, which is far away from the elastic drug storage cavity, wherein an adjusting mechanism is connected between the first micro-flow path and a second micro-flow path, wherein a first valve and a second valve are respectively provided at the surface of the first micro-flow path and adjacent to two different sides of the adjusting mechanism, wherein the disposable wearable micro-flow continuous drug delivery system of the present invention makes the liquid drug have a certain impulse by using the elastic and soft drug storage cavity, which is convenient to inject the liquid drug into the human body, and secondly, the adjusting mechanism is set between the two micro-flow paths, and a plurality of micro valves are set on the two micro-flow paths respectively, which enable the injection volume of the liquid drug to be controlled by controlling the switches of the micro valves located at different positions to help facilitate medical treatment and minimize the effect on the daily living activity of patients.

A valve assembly for a drug delivery device includes a valve housing having a first side and a second side positioned opposite from the first side, a cannula having a first end and a second end positioned opposite the first end, a pierce plate having a body and a piercing member extending from the body, with the body defining a coiled elongate member, and a valve boot connected to the valve housing and defining an interior space. The valve boot is configured to move from a pre-use position where the first end of the cannula and the piercing member of the pierce plate are received within the interior space to a use position where the piercing member of the pierce plate and the first end of the cannula extend outside of the valve boot and the interior space.

The present technology is generally directed to interatrial shunting systems and associated devices and methods. For example, a system configured in accordance with embodiments of the present technology can include a shunting element implantable into a patient at or adjacent a septal wall. The shunting element can have a lumen that fluidly connects a left atrium and a right atrium of the patient to facilitate blood flow therebetween when the shunting element is implanted. In some embodiments, the system further includes a flow control element to selectively control blood flow between the left atrium and the right atrium.

A gas collection unit for use in monitoring and tracking a discharge of air from a patient includes a housing, a set of valves, and a plurality of tubes. The housing contains a first chamber, a second chamber, and a third chamber wherein the chambers are in fluid communication with one another. The housing includes a fluid in the first chamber and the second chamber. The first valve regulates the passage of air flow from the patient into the first chamber and is located within a first tube coupled to the housing. The second valve is in communication with the second chamber. The second valve being configured to regulate the passage of air exiting the first chamber. The second chamber is subjected to a suction. The gas collection unit is operable with an air collection device as a retrofitted item.

A syringe assembly (2) that locks a syringe (10) to prevent backflow of medicament, the syringe assembly (2) comprising a syringe (10) including a barrel (12) configured to carry the medicament, a plunger (14) that communicates with the barrel (12), and a plunger head (16) disposed on a proximal end of the plunger (14), and a locking assembly (50) disposed around the barrel (12), wherein the locking assembly (50) prevents the plunger (14) from moving away from the barrel (12) to draw the medicament into the barrel (12).

A connector system for medical fluid administration has a female connection member, which can act as an access port for a container of medical fluid, and a male connection member, for accessing the container of medical fluid. The female connection member defines a sheath for receiving a portion of the male connection member and this sheath is spanned at one end by a septum, which acts to close the container of medical fluid. A lumen is defined through the male connection member to allow passage of fluid therethrough. The septum has a central region and a peripheral region, the central region being of substantially greater thickness than the peripheral region. The male connection member comprises means for rupturing the peripheral region of the septum when it is received in the female connection member to form a connection.
