Description
Technical field:
The utility model relates to a kind of liquid medicine filters.
Background technique:
Since disposable extension tube can play the role of extension in clinical transfusion, it is widely used in electronics note
Penetrate the products such as pump, electronic transfusion pump.However in infusion process, the foreign matters such as particulate matter in drug also can be with liquid one
It rises and enters in vivo；These can induce cardio-cerebrovascular embolism and lung bolt as liquid enters the foreign matters such as intracorporal particulate matter
The diseases such as plug.Because the foreign matters such as particulate matter are a kind of potential danger to the patient for receiving infusion treatment.Currently, one
Secondary property is the effective ways for preventing the foreign matters such as particulate matter from entering human body using liquid medicine filter is added in extension tube；And it is traditional
Liquid medicine filter need needle tubing and upper cover and lower cover and needle tubing to be bonded together respectively, need that adhesive glue is used for multiple times；And
It can be because there is adhesive glue certain toxicity to generate biggish harm to human body using adhesive glue in the position contacted with medical fluid；Separately
Outside, entire adhesion process complex process, production efficiency are low.
Utility model content:
The utility model provides a kind of liquid medicine filter, can be connected directly with electronic pump class product, serve as extension tube
Medicine outlet connector or mouthful connector that is used as medicine, avoid upper cover from being connected with needle tubing by adhesive glue, reduce toxic contaminants；And it reduces
The process flow that upper cover is connected by adhesive glue with needle tubing, greatly improves work efficiency；It efficiently solves in the prior art
There are the problem of.
Used technical solution is the utility model to solve above-mentioned technical problem:
A kind of liquid medicine filter, including mutually matched upper cover and lower cover and the filtering being assemblied between upper cover and lower cover
Film is equipped with the connector being conducted with filter membrane on upper lid, and the needle tubing being conducted with filter membrane is equipped on lower lid.
The gap for grafting instrument used for injection is equipped between the connector lateral wall and upper cover inner sidewall.
The internal screw thread for being connected with instrument used for injection is equipped on upper cover inner sidewall.
The connector is embedded on lid and connector is longer than upper cover.
Anti-slip part is equipped on upper cover lateral wall.
The anti-slip part is antiskid thread.
The antiskid thread is perpendicular screw thread.
The material of the filter membrane is PP, PES or PA material.
The material of the upper cover is ABS, PP or K resin material.
The material of the lower cover is ABS, PP or K resin material.
The utility model is using the above structure, reasonable in design, by the internal screw thread being arranged on upper lid, makes it can be with
Electronic pump class product is connected directly, and serves as the medicine outlet connector of extension tube or mouthful connector that is used as medicine, and avoids upper cover and needle tubing from passing through viscous
It closes glue to be connected, reduces toxic contaminants；And reduce the process flow that upper cover is connected with needle tubing by adhesive glue, it greatly improves
Working efficiency.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram that the utility model is matched with conduit.
Fig. 2 is the structural schematic diagram of the utility model.
In figure: 1, upper cover, 2, lower cover, 3, filter membrane, 4, connector, 5, needle tubing, 6, internal screw thread, 7, antiskid thread, 8, conduit.
Specific embodiment:
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in figs. 1-2, a kind of liquid medicine filter, including mutually matched upper cover 1 and lower cover 2 and it is assemblied in upper cover
Filter membrane 3 between 1 and lower cover 2 is equipped with the connector 4 being conducted with filter membrane 3 in upper cover 1, is equipped with and filtering on lower cover 2
The needle tubing 5 that film 3 is conducted.
The gap for grafting instrument used for injection is equipped between 4 lateral wall of connector and 1 inner sidewall of upper cover；In upper cover 1
Side wall is equipped with the internal screw thread 6 for being connected with instrument used for injection；The connector 4 is embedded in upper cover 1 and connector 4 is longer than upper cover 1；
It is connected directly it can with electronic pump class product, serve as the medicine outlet connector 4 of extension tube or mouthful connector 4 that is used as medicine, avoid 1 He of upper cover
Needle tubing 5 is connected by adhesive glue, reduces toxic contaminants；And reduce the technique that upper cover 1 is connected with needle tubing 5 by adhesive glue
Process greatly improves work efficiency.
Anti-slip part is equipped on 1 lateral wall of upper cover；The anti-slip part is antiskid thread 7；The antiskid thread 7 is perpendicular spiral shell
Line；The generation of slipping phenomenon when preventing from connecting.
The material of the filter membrane 3 is PP, PES or PA material；Above-mentioned material has extraordinary drug compatibility and life
Object compatibility, nearly all drug will not all change its performance, will not discharge the substance being harmful to the human body, and will not cause because of loading
Material accelerated ageing does not change the chemical property of drug, very small to the absorption of drug, can be ignored, does not have shadow to drug concentration
It rings.
The material of the upper cover 1 is ABS, PP or K resin material；Above-mentioned material has extraordinary drug compatibility, several
All drugs will not all change its performance, will not discharge the substance being harmful to the human body, and material will not be caused to accelerate because of loading old
Change.
The material of the lower cover 2 is ABS, PP or K resin material；Above-mentioned material has extraordinary drug compatibility, several
All drugs will not all change its performance, will not discharge the substance being harmful to the human body, and material will not be caused to accelerate because of loading old
Change.
In use, needle tubing 5 is connected with conduit 8, delivery device pass through the internal screw thread 6 being arranged in upper cover 1 make its with
Electronic pump class product is connected directly between on connector 4, to ensure that liquid medicine filter and electron injection pump class product are combined closely, is prevented
The generation of the phenomenon of leakage；In addition, connector 4 directly serves as the medicine outlet connector 4 of extension tube or mouthful connector 4 that is used as medicine；If connector 4 serves as
Medicine outlet, at this point, the foreign matters such as particulate matter being mixed in medical fluid are blocked in 2 side of lower cover by filter membrane 3；If connector 4 fills
Work as feeding opening, at this point, the foreign matters such as particulate matter being mixed in medical fluid are blocked in 1 side of upper cover by filter membrane 3；It can prevent
The foreign matters such as particulate matter enter inside of human body and do harm to huamn body；In addition, being made by the internal screw thread 6 being arranged in upper cover 1
It can be connected directly with electronic pump class product, serve as the medicine outlet connector 4 of extension tube or mouthful connector 4 that is used as medicine, avoid upper cover 1 and needle
Pipe 5 is connected by adhesive glue, reduces toxic contaminants；And reduce the technique stream that upper cover 1 is connected with needle tubing 5 by adhesive glue
Journey greatly improves work efficiency.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
