The present invention discloses a multi-directional intelligent enema machine, which comprises a first air pump, a first reversing valve, a medicine feeding unit, a first check valve, a heating unit and a first insertion tube which are sequentially connected, and further comprises a first flushing unit, a second flushing unit, a second air pump, an air intake unit, a waste discharge unit and a circuit control unit. The units are connected by a pipeline and controlled and monitored by the circuit control unit. The enema machine of the present invention is safe, reliable, efficient and convenient, and has the functions of liquid infusing, flushing, waste discharging and mixing the intake air and liquid, and can monitor the pressure, temperature and liquid level and so on at the same time.

An enema device for washing a large intestine that can supply water to a large intestine to easily wash and defecate the large intestine. The enema device for washing a large intestine includes a nozzle part inserted into an anal passage and having an ejection hole for ejecting water at one end thereof; a balloon part coupled to an outer peripheral surface of the nozzle part to be expanded; an air pump configured to supply air to the balloon part; a switching valve, to which the air pump is connected; a first water hose, an air hose, and a second water hose; the nozzle part has a discharge hole through which air supplied from the air hose is discharged to the balloon part.

In one embodiment, a door is used to provide uniform pressure to insert tubing into slots of a pump having walls that are narrower than the outer diameter of the tubing. In another embodiment, connectors are attached to receptacles on the pump, where the connectors insert and/or hold the tubing in slots of the pump. The connectors push the tubing into the slots while closing thereby covering the slots, which helps assure that the tubing is properly inserted into the slots. Optionally, the tubing may be partially affixed to the connectors so that detaching the connectors from the pump receptacles may remove the tubing from the slots. In one embodiment, as long as the connectors are connected to the pump receptacles properly, the tubing is properly inserted and/or retained in the slots.

Various exemplary methods, systems, and devices for joint to pump elevation level user interfaces, autocalibration for joint elevation, and joint pressure estimation are provided. In general, an arthroscopic pump can be configured to estimate fluid pressure at a surgical site, e.g., at a joint, to provide an accurate indication of fluid pressure to users. In an exemplary embodiment, the fluid pressure estimation is based on a fluid pressure measurement at the pump that is adjusted at the pump, e.g., by a processor at the pump that executes instructions stored in a memory at the pump, using one or more control algorithms that adjust for one or more factors, such as pressure loss in tubing and sheath through which fluid flows between the pump and the surgical site and elevation difference between the pump and the surgical site.

Technologies are generally described for treatment of ear canal through a micro-dispenser-based treatment system. In some examples, ear canal irrigating fluids may be dispensed in a controlled volume and pressure through one or more micro-dispensers to dissolve and remove ear wax in a gentle and safe manner without harming the eardrum. Through positioning of the micro-dispensers or nozzles of the micro-dispensers, the fluid may be aimed directly at specific areas within the ear canal with a high degree of precision. The micro-dispenser(s) and an optional imaging device such as a camera may be integrated with an otoscope or a cannula for manual manipulation as well as for aiming the fluid jet with visual assessment of cleaning effectiveness

A system and method of receiving a cassette to a console of a phacoemulsification system. The system and method may include receiving the cassette in close proximity to a cassette receptacle comprising a receiving surface, sensing variations in at least two variable resistances mounted respectively diagonally about the receiving surface, and comparing the variations as between the at least two variable resistances to assess an attitude of the cassette. The system and method may optionally include clamping the cassette responsively to the comparing step.

A stool management system having a tubular body including a first end section disposable in a rectum of a patient and a second end section including a first connector which detachably mates with a second connector coupled to a collection container which receives waste matter passed through the tubular body from the bowel of the patient.

An irrigator system for delivering a volume of fluid from a fluid source to an abscess or wound. The irrigator system includes a fluid source connector for removably connecting to the fluid source, a fluid delivery nozzle for delivering the fluid to the abscess or wound, and a shield removably positioned around the fluid delivery nozzle to protect the fluid delivery nozzle.

A phacoemulsification system includes a platform controlling the phacoemulsification process and a handpiece attached to the platform and used by a surgeon to perform an operation. The handpiece includes a hollow phaco needle with a flexible sleeve around the needle and provides an infusion fluid sourced at the platform into the eye. The sleeve, which may be disposable, is provided with a sensor device configured to sense the instantaneous fluid pressure in the eye during the operation and send this information to the platform. This information is used by the process to control the pressure of the infusion fluid to insure that the eye is not injured and to otherwise protect the eye during the operation.

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.
