The present invention comprises a fluid source connected to an irrigation feed line, an aspiration line providing at least a partial vacuum at a surgical site, at least one pressure sensor in communication with the aspiration line, and at least one valve in communication with the irrigation feed line, wherein the at least one valve restricts fluid flow in the irrigation feed line in accordance with at least one measurement of aspiration pressure differential and at least one predetermined system attribute, and wherein the aspiration pressure differential may equal a first measurement of aspiration pressure minus a second measurement of aspiration pressure over a predetermined time.

A device for nasal lavage is described. The device ejects a gentle flow of fluid under pressure. The fluid stream provides a high quantity of fluid at low pressure. The low pressure fluid stream is more comfortable for a user than a high pressure fluid stream that is delivered by some types of pressurized cans of solution.

A drug delivery device capable of forming a medicated mist that reaches the nasal and paranasal sinus cavities contains a puncturing element within its canister. The puncturing element is used in combination with a compartment that contains a filling. The compartment is optionally detachable from an interior of the device or entirely separate from the device. The puncturing element punctures the compartment, releasing the filling into the reservoir of the device to provide a medicated liquid. The device may store any form of medication so long as the medication remains stable. When dry powder forms are desired, the reservoir and/or compartment may be filled with a solution or diluent so as to form the medicated liquid, which may then be dispensed as a mist through the device following the puncturing.

A medical device includes: a hollow body part formed in a predetermined between shape; a head part provided at a tip portion thereof with a discharge port for discharging cleaning water and detachably coupled to a front end of the body part; a connection part connected to a shower hose and a rear end of the body part and provided with a control valve for controlling water supply, a water flow rate and a water pressure; a water purification tube built in the body part and provided with leakage preventing grilles at both ends thereof; and a purified water discharge part provided inside the head part and configured to remove foreign substances in the water by using a filter.

A portable trans anal irrigation device has a hand-held water management unit removably connectable to an irrigation arm. The water management unit includes a water cartridge and a controller. The irrigation arm has a cone head for interfacing with the user's body.

A coupling device for connecting a water powered apparatus to a faucet having a mouth (1) to which a cylindrical aerator housing (3), has an aerator (2) and an attachment (4) of water powered apparatus. The aerator (2) has an upper cylindrical portion (12) and a lower cylindrical portion (15) that are joined together by converging arms (14) between which the ventilation openings (16) are formed for aerating flowing water. The attachment (4) of water powered apparatus is provided with connecting elements for coupling with engagement elements not integral with the aerator cylindrical housing (3).

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.

An oral irrigator has a separate high pressure water system and low pressure mouth rinse system to deliver two different fluids to a pick or other accessories. The water system and mouth rinse system are combined in a handle. The pick is connected to the handle. The water system has a blocking valve located in the handle and the mouth rinse system has a hand pump located in the handle. The hand pump sits next to a valve button for closing the blocking valve. When the hand pump is pressed, it presses against the valve button of the blocking valve to shut off the source of high pressure water to the pick. The pressure in the pick drops so that the hand pump can then introduce mouth rinse into the pick. When the hand pump is released, the blocking valve opens up and high pressure water returns to the pick.
