摘要： A device for carrying out a lavage-like, repetitive supply and draining of a flushing, cleaning or other therapeutically active substance in the context of a return-flow enema, the device comprising: a catheter unit (SK) for receiving and draining feces, which can be permanently placed atraumatically and anorectally; a flushing and collecting bag unit (5, SB) with a combined flushing and collecting function; and a hose unit (4) connecting the catheter unit (SK) to the flushing and collecting bag unit (5, SB), comprising a single-lumen or multi-lumen, film-like, flatly collapsible, hose, and enabling a bidirectional flow communication between the catheter unit (SK) and the flushing and collecting bag unit (5; SB); characterized by at least one throughflow element with a flow-direction-dependent throttle function, providing a large lumen for draining of the patient's intestinal contents into the flushing and collecting bag unit (5; SB), so that shaped stool fractions can be drained, and which facilitates a supply of liquid from the flushing and collecting bag unit (5; SB) towards the patient, but wherein the supply of liquid towards the patient is throttled, so as to be reduced in flow amount or flow speed in relation to the draining of the patient's intestinal contents and thereby reduces the supply of liquid to the patient to a non-irritating amount that is compatible with the patient avoiding painful sensations and/or vegetative responses by an immediate dilation of the patient's colon and/or a triggering of a premature or only partially coordinated defecation reflex.

摘要： A hydrotherapy device for treating a wound on a surface of a patient's body is provided. A body of the hydrotherapy device includes a wall having an outer surface, an inner surface, and a chamber defined by the inner surface. The wall further includes an internal void, a first port extending fully through the wall and in communication with the void, a second port extending from the outer surface partially through the wall and in communication with the void, and a plurality of channels, each extending from the void to the inner surface. A central axis of each channel forms an angle at the inner surface.

摘要： A perfusion control method, apparatus and system for syringe pump, and a computer-readable storage medium, wherein the method includes: when an ablation task is triggered, controlling the syringe pump to execute a perfusion operation on an ablation object, and acquiring an impedance value and/or a temperature value of the ablation object in real time; analyzing the acquired impedance value and/or temperature value to obtain real-time change information of the impedance value and/or temperature value; and adjusting a perfusion amount of the syringe pump dynamically according to the real-time change information obtained from the analysis. By means of the perfusion control method, apparatus and system for syringe pump, and the computer-readable storage medium, dynamic adjustment of the perfusion amount of the syringe pump can be achieved, thereby improving the timeliness and accuracy of liquid perfusion during the process of executing an ablation task.
