The precision filtering infusion set comprises a dropper, a bottle stopper puncture outfit, a drip bucket, a rubber plug, an infusion tube, a flow regulator and an infusion needle. The infusion tube is provided with a precision pharmaceutical solution filter; a nano ion filter membrane is formed in the precision pharmaceutical solution filter; the nano ion filter membrane is fixedly arranged in the precision pharmaceutical solution filter; and the nano ion filter membrane is manufactured by using a high speed ion bombardment technology, and the nano ion filter membrane is manufactured by using a compound filter material fixation technology. The nano ion filter membrane can filter small particles with the diameter of more than 5 micrometers. The precision filtering infusion set has the advantages that the pore diameters of filtration pores are the same through the high speed ion bombardment technology, the filtration pores are uniformly distributed, the small particles with the diameter of more than 5 micrometers can be effectively filtered, the size of the filtration pores cannot be changed by pharmaceutical solution soak for a long time, and the filter membrane cannot be fallen off; and the precision filtering infusion set is stable in filter precision and filtering rate, and good in filtering effect.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of precision filter infusion set.
Background technology
Venous transfusion is a kind of main means on the clinical treatment, so the particularly key that the selection of disposable transfusion device shows therapeutic effect.If select for use ropy transfusion device to carry out venous transfusion; Microgranule in the liquid less than the blood capillary diameter; Like glass chip microgranule, rubber particle, plastic particles, airborne dust, fiber even comprise that some still undissolved medicines can get into blood circulation, cause in that the people is intravital to retain for a long time.Microgranule retains can stimulate body to produce foreign body reaction or anaphylaxis, forms when serious " foreign body granuloma "; Microgranule also can cause the patient to have a fever as pyrogen.Microgranule also can cause the local obstruction of blood vessel or blood supply insufficiency, histanoxia etc. to cause that macrophage infects blood leukocytes and discharges, and inflammatory mediator causes inflammation of vein to be taken place.In recent years, disposable precision filter infusion set is used by increasing medical institutions, and the filter medium of accurate filter is a nucleopore membranes; The filter medium pore-size distribution is more even; Can effectively stop microgranule to get into human body, reduce the stimulation of microgranule, improve the purity of input liquid blood vessel; But existing general infusion set minimum can only be filtered the above microgranule of 15 μ m, and the film material comes off poor filtration effect easily.
Summary of the invention
The purpose of this utility model provides a kind of precision filter infusion set of good filtration effect.
For realizing above-mentioned purpose, the technical scheme that this utility model adopted is:
A kind of precision filter infusion set, comprising: dropper, the upper end of dropper is connected with bottle plug puncture unit; The lower end of dropper is connected with dropping funnel, is designed with plug on the dropper between dropping funnel and the bottle plug puncture unit, and the dropping funnel lower end is designed with tube for transfusion; Be designed with flow regulator on the tube for transfusion, the tube for transfusion lower end is designed with transfusion needle, and its characteristics are: be designed with precision liquid medicine filter on the tube for transfusion; Be designed with the nanoparticle filter membrane in the precision liquid medicine filter; The nanoparticle filter membrane is fixedly mounted in the precision liquid medicine filter, and described nanoparticle filter membrane adopts high-speed ion bombardment fabrication techniques, and described nanoparticle filter membrane adopts combined type filter material technique for fixing to make.
According to above-mentioned precision filter infusion set, its characteristics are: described nanoparticle filter membrane can filter the above fine particles of 5 μ m.
The utility model has the advantages that: this utility model adopts high-speed ion bombardment technology to make the filter opening aperture consistent; And be evenly distributed; Can effectively filter the above fine particles of 5 μ m, can not change the filter opening size through long-time medicinal liquid immersion, filter membrane can not come off; Filtering accuracy and rejection rate are stable, good filtration effect.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is further described:
A kind of precision filter infusion set, like Fig. 1, shown in 2, comprising: dropper 2; The upper end of dropper 2 is connected with bottle plug puncture unit 1, and the lower end of dropper 2 is connected with dropping funnel 4, is designed with plug 3 on the dropper 2 between dropping funnel 4 and the bottle plug puncture unit 1; Dropping funnel 4 lower ends are designed with tube for transfusion 5; Be designed with flow regulator 6 on the tube for transfusion 5, tube for transfusion 5 lower ends are designed with transfusion needle 8, are designed with precision liquid medicine filter 7 on the tube for transfusion 5; Be designed with nanoparticle filter membrane 9 in the precision liquid medicine filter 7; Nanoparticle filter membrane 9 is fixedly mounted in the precision liquid medicine filter 7, and nanoparticle filter membrane 9 adopts high-speed ion bombardment fabrication techniques, and nanoparticle filter membrane 9 adopts combined type filter material technique for fixing to make.
In the present embodiment, nanoparticle filter membrane 9 can effectively filter the above fine particles of 5 μ m, and the microgranule rejection rate reaches more than 90%.
The beneficial effect of this utility model is: the filter membrane in this utility model adopts the nanoparticle filter membrane, changes traditional fibrous membrane, and the nanoparticle filter membrane does not have the medicinal liquid adsorptivity.The nanoparticle filter membrane adopts combined type filter material technique for fixing, and long-time medicinal liquid immersion does not produce foreign body and comes off.The nanoparticle filter membrane adopts high-speed ion bombardment technology to make the filter opening aperture of filter membrane consistent; Be evenly distributed; The long-time immersion of medicinal liquid can not change the filter opening size; Filtering accuracy and rejection rate are stable, have solved current disposable transfusion device and can not filtering have stopped up blood capillary insoluble microparticle and the filter membrane disadvantage with medicine absorption that comes off.
Embodiment recited above describes the preferred implementation of this utility model; Be not that design and protection domain to this utility model limits; Under the prerequisite that does not break away from this utility model design concept; Common engineers and technicians make the technical scheme of this utility model in this area various modification and improvement all should fall into the protection domain of this utility model.
