摘要:
A surgical suction device that uses positive pressure gas is shown and described. The surgical suction device includes an air amplifier. The air amplifier includes a structure defining a generally cylindrical cavity having a first opening at a first end and a second opening at a second end. The cylindrical cavity is defined by an inner wall of the cavity. The air amplifier includes an annular opening in the inner wall near the first end. The annular opening defines a jet opening adapted to allow a pressurized gas to flow out of the annular opening such that a low pressure region is produced at the first end and an amplified flow is produced at the second end. The annular opening is further configured such that the pressurized gas enters the cavity at an angle with respect to the inner wall of the cavity that is towards the second end.
摘要:
An elastomeric acoustic coupler formed by molding a thermoplastic or silicone rubber into a recess of a surgical cassette housing. The coupling has a raised pad to aid in the removal of all air between the transducer and the fluid conduit, and to provide an efficient transmission of an ultrasound signal into the fluid conduit.

An electric breast pump is disclosed as including a hood (12) to be fitted over a breast of a user, a chamber (37) in fluid communication with the hood member (12) via a one-way valve (48), a pump motor (42) operatively associated with a pump diaphragm (44) movable to draw air from the hood (12) into the chamber (37) via the valve (48), in which the chamber has an opening and a lid (66) which is operatively associated with the motor (42), in which the lid (66) is movable between a first position to close the opening and a second position in which the opening is open, and in which the lid (66) is at the first position when the motor (42) is in operation and is at the second position when the motor (42) is not in operation. The breast pump also includes sensors (38a,38b) for detecting the passing of milk, and a microcontroller (40) for calculating the rate of flow of milk on the basis of data received from the sensors (38a,38b).

摘要:
Apparatus and methods for alerting a user of topical negative pressure therapy apparatus to a non-flow condition of aspirant fluid in the apparatus are described, the apparatus comprising: a device having vacuum pump means and a waste canister connected to the device; the waste canister being operably connected to a wound dressing by aspiration conduit means for aspirating fluid from the wound; the aspiration conduit means, the waste canister and the device providing a fluid flow path therethrough and the vacuum pump means providing for fluid flow therethrough; the device having first pressure sensing means at an upstream position between an outlet port for aspirated fluid from said waste canister and said pump means; said waste canister having further provision selected from one of, selectable vent means for admission of ambient air to said waste canister and selectable second pressure sensing means for sensing pressure in said waste canister; and, a control system for receiving signals from said sensors and initiating control signals in response and activating an appropriate user alarm.
摘要:
A negative pressure wound therapy system with an alarm function for the flow rate of exudate comprises a liquid collecting bottle (5) for collecting wound exudate, a negative pressure wound therapy device (8) consisting of a negative pressure source (6) and a controller (7), and a wound kit for filling and enclosing the wound, which communicates with the liquid collecting bottle (5) via a connecting tube (4). The system further comprises a flow rate alarm processing module and an alarm warning device. If the flow rate of exudate is greater than a predefined value, the flow rate alarm processing module issues an alarm instruction. The alarm warning device sends a warning message according to the alarm instruction. If the flow rate of exudate is greater than the predefined value, the system issues an alarm instruction to the alarm warning device, by which a warning message is sent to remind medical staffs of timely inspection, thereby avoiding occurrences of serious accidents, such as the blood in human body being sucked out, and so on.
