Detailed description of the invention
As a rule, vein treatment device as herein described is used to supply therapeutic fluid stream (such as, being with or without the normal saline of pharmaceutically active substance) to experimenter.Vein treatment device as herein described comprises filter assemblies, and before liquid is introduced in subject, liquid stream is through this filter assemblies.This filter partly or entirely may remove the exotic (such as, microgranule) in liquid stream.
In certain embodiments, vein treatment device comprises the liquid memory that therapeutic fluid is housed at least partly.Vein treatment device also comprises and will be connected to the liquid filter assemblies of liquid memory.This filter assemblies may comprise filter shell and be positioned at the filter element of described filter shell.This filter assemblies is sealing at first, avoids contacting with therapeutic fluid.In other words, before vein treatment device uses, therapeutic fluid is avoided contacting with filter assemblies.
Vein treatment device may comprise in one or more conveying liquid to subject and receive the interface of the liquid by being added into liquid memory.Filter assemblies may be connected to vein treatment device in the coupling part of this one or more interface.In one embodiment, hub-interface (central port) comprises outlet, and (fluid-tight) mode that the inlet tube of the filter shell of filter assemblies seals with basic liquid is embedded into this outlet.The inlet tube of filter shell may comprise the part of sealing or the film (such as, the sealing of liquid memory and/or the sealing of filter shell) being set to pierce through vein treatment device.Such as, filter shell may comprise a significantly outstanding part, such as puncture needle.In other embodiments, piercing portions or puncture needle are positioned on another parts of vein treatment device, and filter shell is connected on these parts in the downside (downstream side) of these parts.Removable stopping means (such as, ring (collar)) may be positioned on the inlet tube of filter shell, stops inlet tube to be fully inserted into the outlet of hub-interface.
Film phonograph seal may be positioned at hub-interface, stops filter assemblies to contact with the therapeutic fluid in liquid memory.When operator wants to use this vein treatment device, peripheral IV conduit is inserted in the outlet of filter assemblies by this operator, and shift(ing) ring.The inlet tube of filter shell is inserted in the outlet of hub-interface by operator completely, makes piercing portions or this film phonograph seal of needle pierces.Then, therapeutic fluid flows through filter assemblies, enters into peripheral IV conduit, arrives injection site (such as, experimenter pin injection site with it) through this peripheral IV conduit.
In certain embodiments, liquid filter comprises the sealing being positioned at the one or more end of liquid filter (such as, the port of export of liquid filter).Sealing stops liquid to flow through liquid filter at first and/or stops from external contaminants (pathogen such as, in dust, air) to enter filter before use.When using this vein treatment device, sealing destroyed (such as, removing) (such as, by a part for peripheral IV conduit is inserted in the outlet of liquid filter).
In other embodiments, filter assemblies passes through, and such as, flexible pipe (flexible tube) is connected on liquid memory.Filter assemblies may be fixedly attached on flexible pipe, such as, by binding agent, maybe may be movably connected on flexible pipe, such as, by adapter (such as, female Luer connects).Flexible pipe may be provided with removable fixture (clamp).Fixture may be set to squeezing tube, to make the internal path of flexible pipe be closed, stops therapeutic fluid to contact with filter assemblies.
In use, a part for peripheral IV conduit is inserted in the outlet of liquid filter by operator.Subsequently, fixture removes from flexible pipe by operator, thus makes therapeutic fluid flow through filter assemblies, enters peripheral IV conduit, finally reaches injection site (such as, experimenter pin injection site with it).
In certain embodiments, liquid memory may be divided into the dress liquid part and drying nest of holding therapeutic fluid at first.Filter assemblies is positioned at the drying nest of liquid memory, and initial and therapeutic fluid is isolated.This filter assemblies may be connected to run through fluid storage wall interface on.
Liquid memory may be prepared by elastic polymeric material.Fluid storage wall folder (such as, strangling) clamping strip together (bar clamp) may to be separated across liquid memory, with the drying nest of fluid partitioning bin and dress liquid part by liquid memory.In use, a part for operator or health care provider can connect (such as, insert) peripheral IV conduit in interface, and removes clamping strip, thus make therapeutic fluid both be full of initial dress liquid part, be also full of initial drying nest.Therapeutic fluid may soak into and flow through filter assemblies, enters peripheral IV conduit, final arrival pin injection site.
