Abstract

The present utility model one resistance cingula cap infusion connector, comprise female joint, filter membrane, block, male joint four part, can operate, germ contamination separation membrane can be intercepted and be easy to be connected with central venous catheter or remaining needle by easy tube sealing in long-term infusion, transfusion procedure.

Description

Resistance cingula cap infusion connector
Technical field
This utility model belongs to a kind of infusion connection device, relates generally to a kind of resistance cingula cap infusion connector.
Background technology
Need the patient clinical of long-term infusion, treatment of blood transfusion to treat and usually adopt central vein catheter or use remaining needle to avoid repeatedly puncturing to vein causing venous injury, increase patient suffering.Once infuse in using, having transfused blood is separated transfusion or blood exchange transfusion set with central venous catheter or remaining needle, central venous catheter or remaining needle are stayed in patient body, bring convenience to the activity of patient.Clinically in use find, central venous catheter or remaining needle often adopt the materials such as calparine cap, gauze tube sealing, normal saline to carry out tube sealing, increase nursing time and labor intensity; Carry out tube sealing if select with the infusion connector of common band separation membrane, can reduce nursing time and labor intensity, but common infusion connector exists open at one end, separation membrane is easily contaminated, pollutes to secondary transfusion or blood transfusion; Joint design is simple, cannot expire Clinical practice requirement.
In view of above deficiency, special hope can be invented one and can be operated, avoids separation membrane to pollute by easy tube sealing, and simple infusion connector.
Summary of the invention
The present utility model a kind of can easy tube sealing operation in long-term infusion, transfusion procedure, germ contamination separation membrane can be intercepted and be easy to the resistance cingula cap infusion connector that is connected with central venous catheter or remaining needle.
In order to reach above object, the technical scheme adopted is: resistance cingula cap infusion connector, and comprise female joint, filter membrane, block, male joint four part, one end of block is connected with male joint, filter membrane is welded on one end of male joint, and male joint is fixedly connected with the mode of female joint by welding.
As further technical scheme, described female joint is injection molded by macromolecular material, inner chamber hollow, and one end is Rule female joint structure, and the other end is a disk, opens a hole identical with female joint intracavity diameter size in the middle of disk.
As further technical scheme, described male joint is injection molded by macromolecular material, inner chamber hollow, one end is the disk identical with described female joint disk size, disk arranges press mold muscle according to the position of diameter, a hole identical with male joint intracavity diameter size is opened in centre, and the other end is movable Rule male joint structure.
As further technical scheme, described filter membrane diameter is identical with described disk diameter, is fixed on the disk of male joint by the mode of welding, and filter membrane has can the aperture of most of common bacteria and microgranule in filtering medicinal liquid.
Further, described block one end is an annulus, is enclosed within male joint, the other end is a lid, dowel between described annulus and described lid can bend, described lid built-in can with two screw threads of female joint closed butt joint, cover bottom arranges a sterilization cotton pad.
This utility model in use, male joint is connected fastening with venous duct, to outward winding block, female joint and transfusion device, blood exchange transfusion set or syringe are carried out docking and carries out infusing, transfusing blood or flushing operation, after end of operation, block and female joint are screwed, can avoid antibacterial or microgranule access to plant inner chamber, filter membrane has can filtering major part common bacteria and the aperture of microgranule, if there is antibacterial to enter inner chamber in operation, filter membrane can retain it, reaches the effect of resistance bacterium.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is profile of the present utility model.
1 be female joint 1 in figure, male joint 2,2 be filter membrane 3 in block 4, figure, disk 11, press mold muscle 21, annulus 41, dowel 42, cotton pad 43 of sterilizing.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
As shown in Figure 1, 2, resistance cingula cap infusion connector, comprises female joint 1, male joint 2, filter membrane 3, block 4.Female joint 1, male joint 2, block 4 adopt macromolecular materials injection molded, and filter membrane 3 is can the filter membrane of majority of particles and antibacterial in filtering medicinal liquid.The annulus 41 of the block 4 injection moulding completed is inserted in female joint 1, sterilization cotton pad 43 is loaded in block 4.
