Abstract
Disposable secondary filter fluid-directing needle, the drain syringe needle that it includes a cartridge filter body and body both ends are made into integration, a barrel type filtering body that peripheral wall is mainly made of liquid medicine filtering membrane is axially disposed in the body, the middle cavity of drain hole link barrel type filtering body in the axial direction drain syringe needle of body one side, and the drain duct linker intracoelomic cavity in body opposite side axial direction drain syringe needle, and the drain duct in the axial direction drain syringe needle of body both sides is made to be connected by the liquid medicine filtering membrane of barrel type filtering body peripheral wall；The barrel type filtering frame that the barrel type filtering body is closed by one end open one end is formed 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 one side and against the drain duct in axial drain syringe needle, and the other end of the barrel type filtering frame is supported on device cavity side wall；It has it is simple in structure, it is easy to use, moreover it is possible to liquid carry out secondary filter the features such as.
Description
Technical field
The utility model relates to a kind of disposable secondary filter fluid-directing needles, are mainly used for clinic two and are transfused liquid
Match somebody with somebody liquid between container；Belong to the field of medical instrument technology.
Background technology
After people see a doctor in hospital, drop drop is had an injection or beaten if necessary（Hang brine）Deng generally requiring medicament configuration
Into liquid, it is common practice to：Syringe is extracted into solution, and solution is filled and carries out shaking in flask for medicinal preparations, is configured to liquid, so
Liquid extraction is directly squeezed into syringe again afterwards in the muscle of human body or in injection saline bottle.The collocation method of this liquid is not only
Cumbersome and very dangerous, some medicaments are difficult dissolving by solvent, if without thoroughly dissolving, first, drug effect will
It reduces, medicament is caused to waste, second is that it is dangerous, easily the granular drug not dissolved thoroughly also being suspended in liquid is squeezed into
In the skin of human body.
The content of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and offer is a kind of simple in structure, uses behaviour
Facilitate, securely and reliably, the dissolving of medicament can not only be facilitated, moreover it is possible to the disposable precision of secondary filter is carried out to liquid
Filter fluid-directing needle.
The purpose of this utility model is completed by following technical solution, a kind of disposable secondary filter drain
Pin, it includes the drain syringe needle that a cartridge filter body and body both ends are made into integration, is axially disposed in the body
One is mainly made of the barrel type filtering body of peripheral wall liquid medicine filtering membrane, the drain hole link cylinder in the axial direction drain syringe needle of body one side
The middle cavity of formula filtering body, and the drain duct linker intracoelomic cavity in body opposite side axial direction drain syringe needle, and make body
Drain duct in the axial direction drain syringe needle of both sides is connected by the liquid medicine filtering membrane of barrel type filtering body peripheral wall.
As preferred：The 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 are fixed therein one 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 utility model belongs to a kind of improvement to the prior art, it have it is simple in structure, use is easy to operate, safely may be used
It leans on, the dissolving of medicament can not only be facilitated, moreover it is possible to the features such as secondary filter is carried out to liquid.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing：Shown in Fig. 1, described in the utility model a kind of one
Secondary property uses secondary filter fluid-directing needle, the drain syringe needle 2 that it includes a cartridge filter body 1 and body both ends are made into integration,
A barrel type filtering body 4 that peripheral wall is mainly made of liquid medicine filtering membrane 3 is axially disposed in the body 1,1 one side of body is axial
Drain duct 5 in drain syringe needle 2 connects the middle cavity 6 of barrel type filtering body 4, and in 1 opposite side axial direction drain syringe needle 2 of body
Drain duct 7 connect device cavity 8, and make the drain duct 5,7 in 1 both sides axial direction drain syringe needle 2 of body by cartridge type mistake
The liquid medicine filtering membrane 3 of 4 peripheral wall of filter body is connected.
Barrel type filtering body 4 described in the utility model is the barrel type filtering frame 9 closed by one end open one end and is coated on
The liquid medicine filtering membrane 3 of 9 periphery of barrel type filtering frame forms, and the one end open 10 of the barrel type filtering frame 9 is fixed therein one side device
On 1 inner cavity end wall of body and against the drain duct 5 in axial drain syringe needle 2, the other end of the barrel type filtering frame 9 supports
On 1 intracavity sidewall of body.
The utility model carries out secondary filter when making up a prescription, by the liquid medicine filtering membrane in fluid-directing needle to liquid, ensures medicine
The safe handling of liquid.
