Abstract
A kind of disposable secondary filter fluid-directing needle, it includes the drain syringe needle that a cartridge filter body and body two ends are made into integration, a main barrel type filtering body that perisporium is made up of liquid medicine filtering membrane is axially disposed with described body, the middle cavity of drain hole link barrel type filtering body in the drain syringe needle of body side axial direction, and the drain duct linker intracoelomic cavity in the axial drain syringe needle of body opposite side, and the drain duct in the axial drain syringe needle in body both sides is connected by the liquid medicine filtering membrane of barrel type filtering body perisporium；The barrel type filtering frame that described barrel type filtering body is closed by one end open one end is constituted with the liquid medicine filtering membrane for being coated on barrel type filtering frame periphery, the one end open of the barrel type filtering frame is fixed therein on the device cavity end wall of side and against the drain duct in axial drain syringe needle, and the other end of the barrel type filtering frame is supported on the wall of device cavity side；It has it is simple in construction, it is easy to use, moreover it is possible to decoction carry out secondary filter the features such as.
Description
Technical field
The present invention relates to a kind of disposable secondary filter fluid-directing needle, it is mainly used in clinic two and is transfused medical liquid container
Between match somebody with somebody liquid；Belong to technical field of medical instruments.
Background technology
After people see a doctor in hospital, drop drop is had an injection or beaten if desired（Hang salt solution）Deng generally requiring medicament configuration
Into decoction, it is common practice to：Syringe is extracted into solution, and solution is filled into progress in flask for medicinal preparations and is shaken, decoction is configured to, so
Decoction is extracted out in the muscle for directly squeezing into human body or in injection saline bottle with syringe again afterwards.The collocation method of this decoction is not only
Cumbersome and very dangerous, some medicaments are difficult dissolving by solvent, if without thoroughly dissolving, one is that drug effect will
Reduction, causes medicament to waste, two be dangerous, easily squeezes into the granular drug not dissolved thoroughly also being suspended in decoction
In the skin of human body.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of simple in construction, use operation side
Just, it is safe and reliable, the dissolving of medicament can not only be facilitated, moreover it is possible to the disposable secondary filter of secondary filter is carried out to decoction
Fluid-directing needle.
The purpose of the present invention is completed by following technical solution, a kind of disposable secondary filter fluid-directing needle,
It includes axially being disposed with a master in the drain syringe needle that a cartridge filter body and body two ends are made into integration, described body
The drain hole link cartridge type mistake in the barrel type filtering body of perisporium, body side axial direction drain syringe needle is made up of liquid medicine filtering membrane
The middle cavity of filter body, and the drain duct linker intracoelomic cavity in the axial drain syringe needle of body opposite side, and make body both sides
Drain duct in axial drain syringe needle is connected by the liquid medicine filtering membrane of barrel type filtering body perisporium.
As preferred：Described barrel type filtering body is the barrel type filtering frame closed by one end open one end and is coated on cartridge type
The liquid medicine filtering membrane composition of filtering frame periphery, the one end open of the barrel type filtering frame is fixed therein side device cavity end wall
Above and against the drain duct in axial drain syringe needle, the other end of the barrel type filtering frame is supported on device cavity side wall
On.
The invention belongs to prior art one kind improve, it have it is simple in construction, it is safe and reliable using easy to operate,
The dissolving of medicament can not only be facilitated, moreover it is possible to the features such as secondary filter is carried out to decoction.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1, one kind of the present invention is disposable
Secondary filter fluid-directing needle, it includes the drain syringe needle 2 that a cartridge filter body 1 and body two ends are made into integration, described device
A main barrel type filtering body 4 that perisporium is made up of liquid medicine filtering membrane 3, the side of body 1 axial direction drain syringe needle are axially disposed with body 1
The middle cavity 6 of the connection barrel type filtering body of drain duct 54 in 2, and the delivery hole in the axial drain syringe needle 2 of the opposite side of body 1
Road 7 connects device cavity 8, and the drain duct 5,7 in the axial drain syringe needle 2 in the both sides of body 1 is passed through the perisporium of barrel type filtering body 4
Liquid medicine filtering membrane 3 be connected.
Barrel type filtering body 4 of the present invention is the barrel type filtering frame 9 closed by one end open one end and is coated on cartridge type
The liquid medicine filtering membrane 3 of the periphery of filtering frame 9 is constituted, and the one end open 10 of the barrel type filtering frame 9 is fixed therein in side body 1
On chamber end wall and against the drain duct 5 in axial drain syringe needle 2, the other end of the barrel type filtering frame 9 is supported on body
On 1 intracavity sidewall.
The present invention carries out secondary filter, it is ensured that decoction by the liquid medicine filtering membrane in fluid-directing needle when making up a prescription to decoction
Safe handling.
