Multiple remote database connections to mongodb in meteor

When using“collectioName”) in meteor for each db operation a new connection is created it even reaches 1000 connections in mongodb for a single user. Is there any way to close connection to database when using“collectioName”) or open connection to remote databases for each user only once and access collections when needed ?

for each database operation (insert, update, remove) I am using this code to get collection from remote database and insert/edit/delete a doc.

var database = new MongoInternals.RemoteCollectionDriver(mongoUrlUsers 
 + company_id);
var collection ="system");

        company: company_id,
        mainMobile: userMobile,
        createdAt: new Date(),
        system: true});
