Definition : Pumps designed to deliver liquids (i.e., irrigate) to a cavity or other specific area of the body. These pumps typically consist of a central unit with a pumping (e.g., peristaltic) mechanism; a control (e.g., a valve, clamp, or manual or foot-switch) to regulate the rate of the irrigation; and detachable (frequently disposable) tubing appropriate for irrigation of the intended body cavity or area. Irrigation pumps intended for particular equipment such as surgical, dental, and nasal irrigators are available; dedicated irrigation pumps intended for use with appropriate tubing coupled to irrigation catheters or cannulae are also available.

Information on how to use Search
There are 2 types of basic queries: Terms and Phrases.
A Term is a single word search.
A Phrase would wrap a string of words in quotes and find matches on the extact string.
Boolean Operators You can combine basic queries with Boolean operators to form a more complex query. Boolean operators define the relationships between Terms or Phrases. Our search supports the following Boolean operators: AND, "+", OR, NOT and "-". Please note that Boolean operators must be all uppercase.
AND example search: default AND document
This is the default operator. It will be used if there is no Boolean operator between two terms. For example:
default document is the same as default AND document. In this case both terms need to exist within a listing to find a match on that listing.The + character is synonymous with using AND.
OR example search: default OR document
In this case just one of the terms needs to exist within a listing to find a match on that listing.
NOT example search: default NOT "document type"
The NOT operator excludes documents that contain the term (or phrase) after NOT. So a listing match would have to include the word default but not the phrase "document type". The - character is synonymous with using NOT.
Wildcard/Prefix queries You can perform "wildcard" or "prefix" queries using the '*' operator. Whereas all of the previous search found exact matches on the whole term or phrase, a wildcard search will find partial matches.
example search: ehr*
This query will match all documents containing words beginning with the prefix 'ehr' like the word Ehrlichia.
