Abstract
This utility model is a kind of secondary filter Medical tee joint, belongs to technical field of medical instruments, particularly relates to a kind of Medical tee joint.The utility model discloses a kind of secondary filter Medical tee joint, comprise three-way body, switching valve, joint.Joint inside is provided with one or more layers hydrophilic secondary filter film, and the joint sidewall above hydrophilic secondary filter film is provided with some steam vents, and steam vent inside is provided with hydrophobicity gas phase membrane.The beneficial effects of the utility model are: the filtration of the hydrophilic secondary filter film located by three way cock, ensure medicinal liquid when Medical tee joint enters human body through secondary filter, reach the effect of secondary filter transfusion equally, prevent the harm that the microgranule that exists in medicinal liquid and bubble cause human body.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of Medical tee joint.
Background technology
As far back as the thirties in 20th century, just find that in infusion process, patient there will be multiple infusion reaction clinically, and there is special pathogenic side effect.The 1950's, numerous scholar reports the harm of microgranule in transfusion.The a large amount of particulate matters (carbon granule, antibacterial, fat embolus, rubber, plastics etc.) existed in medicinal liquid are after transfusion enters human body, potential and long-term harm (reaction of phlebitis, thromboembolism, tissue necrosis, granuloma, pyrogen sample, anaphylaxis) can be produced to human body, sometimes even directly injure life.
The Major Clinical harm that microgranule causes has the following aspects.One, anaphylaxis.The drug crystallization microgranule contained in medicine, polymer, degradation product and other foreign bodies can react at injection site or vein blood vessel and histone, cause allergic reaction.Two, phlebitis.Microgranule, after entering human body, causes blood vessel to stimulate damage with blood circulation, the normal condition of blood vessel wall is changed, causes platelet to stick together, cause phlebitic generation.Three, blood vessel embolism.Particulate matter causes blocking in the thin vessels at the places such as brain, lung, kidney, liver, eye, causes tissue necrosis in various degree and damage.Four, microcirculation is blocked.Adult's capillary blood vessel diameter is 6 ~ 8 microns, and baby is only 3 microns.In medicinal liquid, diameter is greater than the microgranule of blood capillary diameter, can block blood capillary, forms microcirculation disturbance.Five, arteriosclerosis.Microgranule can cause tremulous pulse non-inflammation pathological changes, ductus arteriosus wall is thickened, hardening, and follow the string, tube chamber is narrow and small.Six, pyrogen reaction.The symptoms such as the shiver with cold caused during transfusion, high heat, are called as pyrogen reaction.Seven, granuloma.When microgranule intrusion lung, brain, kidney etc. are organized in blood capillary, macrophage proliferation can be caused, form granuloma, thus cause the position blood supply insufficiencies in various degree such as brain, lung, kidney and eye, cause circulatory disturbance.Eight, pulmonary infarction.When blood arrives after pulmonary through circulation, the capillary bed of lung plays filter screen effect, a part of microgranule is stayed and is attached in blood vessel wall, easily form pulmonary infarction, granuloma.
The precise filtering device that precision infusion set comprises can microgranule effectively in filtering liquid medicine, widely uses clinically at present.And Medical tee joint is mainly used in pushing medicinal liquid through syringe in infusion process and pumping into medicine through microinfusion pump, same extensive use in clinical.Because Medical tee joint can only be series at the downstream of precision infusion set or blood exchange transfusion set, the medicine thus given through Medical tee joint all directly enters human body without the filtration of precise filtering device, thus works the mischief to health.In addition, be difficult to invariably a small amount of bubble together to be pushed blood vessel when Medical tee joint injection liquid, be unfavorable for health equally.
Utility model content
This utility model object is to make medicinal liquid when Medical tee joint enters human body through secondary filter, reaches the effect of secondary filter transfusion equally.
Based on above-mentioned technical though, the technical scheme that this utility model realizes its object is:
A kind of secondary filter Medical tee joint, comprises three-way body, switching valve, joint.Upper square joint inside is provided with one or more layers hydrophilic secondary filter film, and the joint sidewall above hydrophilic secondary filter film is provided with some steam vents, and steam vent inside is provided with hydrophobicity gas phase membrane.
Three-way body centre described in the utility model is provided with switching valve.
Described three-way body inside communicates with each other, and the left and right sides and top are provided with joint.Right-hand joint is provided with protective cap, and right-hand joint and protective cap screw in locking cap.Left-hand joint and upper square joint are provided with screw-cap.
The beneficial effects of the utility model are: the filtration of the hydrophilic secondary filter film located by three way cock, ensure medicinal liquid when Medical tee joint enters human body through secondary filter, reach the effect of secondary filter transfusion equally, prevent the harm that the microgranule that exists in medicinal liquid and bubble cause human body.
Accompanying drawing explanation
According to embodiment and accompanying drawing, this utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of secondary filter Medical tee joint described in the utility model.
In figure:
1, three-way body; 2, switching valve; 3, joint; 3-1, right-hand joint; 3-2, left-hand joint; 3-3, upper square joint; 4, protective cap; 5, locking cap; 6, screw-cap; 7, hydrophilic secondary filter film; 8, steam vent.
Detailed description of the invention
As shown in Figure 1, a kind of secondary filter Medical tee joint described in the utility model, comprises three-way body 1, switching valve 2, joint 3.Described three-way body 1 left and right sides and top are provided with joint 3.Right-hand joint 3-1 is provided with protective cap 4, and right-hand joint 3-1 and protective cap 4 screw in locking cap 5.Left-hand joint 3-2 and upper square joint 3-3 is provided with screw-cap 6.
Described upper square joint 3-3 inside is provided with one or more layers hydrophilic secondary filter film 7, and the joint sidewall above hydrophilic secondary filter film 7 is provided with some steam vents 8, and steam vent 8 inside is provided with hydrophobicity gas phase membrane.
Described hydrophilic secondary filter film 7 is preferably the poly (ether sulfone) film that aperture is 5 microns.Described steam vent 8 is preferably 3 steam vents of equidistantly distribution, and aperture is preferably 2mm.
Described three-way body 1 centre is provided with switching valve 2.
Described three-way body 1 inside communicates with each other.
During use, the syringe that medicine is housed is closely coupled to top interface 3-3, and both scalable was in three whole connected states of joint for switching valve 2, and also scalable is in right-hand joint 3-1 and upper square joint 3-3 two fittings states.In injection liquid process, it is inner that medicinal liquid enters three-way body 1 after hydrophilic secondary filter film 7 filters, and microgranule and bubble are stopped by hydrophilic secondary filter film 7, and bubble is discharged through steam vent 8.
This utility model trial effect is definite, well achieves original intention of the present utility model.
Above-described is only exemplary embodiment of the present utility model, not in order to limit this utility model.Should be understood that; to those skilled in the art; under the prerequisite not departing from this utility model structure; also can make suitable distortion, improvement, equivalent replacement; or only using this utility model partial content also should be considered as protection domain of the present utility model, these do not affect effect and the practical applicability of this utility model enforcement.
