Abstract
The utility model provides an air filter matched with a disposable infusion device, adopting a hollow casing. A felt-shaped filtering piece is arranged between the casing and a press cover with a protective cap, all the air filtered enters a clean air chamber through the felt-shaped filtering piece, the clean air chamber is communicated with a pipe-shaped joint whose middle part is provided with a small hole, and the utility model is directly inserted at the opening of the air inlet pipe of an infusion bottle inserting needle. The utility model has the advantages that the utility model can thoroughly filter dust microparticles >or = 0.5 microns and microorganisms entering the air in a medicine bottle, can prevent physic liquor from overflowing, protects the physic liquor from polluting, and ensures infusion safety.
Description
This utility model belongs to the matching component of clinical transfusion device in the medicine and hygiene fields, the supporting air filter of using of particularly a kind of disposable infusion set.
When needs of patients being accepted the venous transfusion treatment, be extensive use of disposable infusion set at present.This has played positive effect to preventing and curing diseases, prevent cross infection, but, present employed disposable infusion set is the defecator that enters air in the bottle when dress plug one fritter plastic sponge is as transfusion in air induction hose, it only can the filtering air in bigger floating dust microgranule, to almost not having filtration than small particle and the microorganism of adhering to, certainly will cause secondary pollution to medicinal liquid in this air admission infusion bottle without filtering microorganism and dirt particle, this will be one of potential hazard factor that causes the heart, brain, angiopathy.Simultaneously, this defecator directly leads in air, and very easily the messenger drug hydrorrhea flows out when transfusion operation, and during normal infusion, the medicinal liquid at the defecator position is back in the infusion vessel and goes, and the probability of liquid medicine contamination is very big.
The purpose of this utility model is to provide the air filter on the air inlet pipe of a kind of plastics needle for inserting bottle that is directly installed on disposable infusion set or metal needle for inserting bottle needle stand, make its air that when transfusion, enters in the infusion vessel all be filtered purification, thereby reach the air dust-free sterile that enters in the medicinal liquid by filter.Simultaneously during transfusion operation because of air filter meet the gas face have a protection cap not the messenger drug hydrorrhea flow out, make medicinal liquid not contaminated, guarantee the safety of infusing.
The purpose of this utility model is to realize like this; the supporting air filter of using of disposable infusion set is by hollow housing; the gland of felted filter disc and band protective cap constitutes; one clean air chamber (7) is arranged in the middle of the hollow housing (1); in the middle of the tubular configured joint (8) of hollow housing (1) conical end, there is a band tapering aperture (5) to communicate with clean air chamber (7); hollow housing (1) garden styletable has a boss (6); lay the felted filter disc (2) that the usefulness ultra-fine resin fibre identical with boss (6) external diameter made at boss (6); the gland (3) of felted filter disc (2) external band protective cap (4) tightly covers on hollow housing (1) garden styletable boss (6); the boss periphery links fixing with adhesive and gland (3); clamp felted filter disc (2); the convex surface of protective cap (4) is pressed and is covered the meeting on the gas face of gland (3), is network structure in the middle of the gland (3).A soft linking belt (9) links between gland made from non-toxic plastic integral body (3) and the protective cap (4), and the opposite side of protective cap (4) has a hand-held stalklet (10) of easily opening protective cap.Have a band tapering aperture (5) one ends to communicate with clean air chamber (7) in the middle of the tubular configured joint (8) of hollow housing (1) garden awl end, the other end directly cover is inserted on the transfusion device needle for inserting bottle air inlet pipe, and the profile of hollow housing (1) can be made the garden cylindricality.
Be described in detail with air filter this utility model disposable infusion set is supporting below in conjunction with accompanying drawing.
Fig. 1 is the figure after air filter and transfusion device needle for inserting bottle cover are inserted.
Fig. 2 is the supporting air filter arrangement figure that uses of this utility model disposable infusion set.
The supporting hollow housing (1) with air filter of disposable infusion set is that circular cone and cylinder are in conjunction with shape; there is a clean air chamber (7) centre; the hollow housing conical tip has a band internal taper tubular configured joint (8); there is an aperture (5) to communicate in the middle of the band internal taper tubular configured joint (8) with clean air chamber (7); on hollow housing cylindrical end boss (6), lay the felted filter disc (2) identical with boss (6) external diameter; its felted filter disc (2) is to make with ultra-fine resin fibre; have and stop in the air 〉=effect that 0.5um dirt particle and microorganism enter clean air chamber (7); gland (3) at felted filter disc (2) external band protective cap (4) tightly covers on hollow housing (1) cylindrical end plano-convex platform (6); in the middle of the gland (3) is netted capping; to guarantee to have enough air inflows; boss (6) periphery links fixing with the gland (3) of band protective cap (4) with adhesive; compress felted filter disc (2) all around; in case unholiness escape of air; protective cap (4) is an integral body with gland (3); it between protective cap (4) and the gland a soft linking belt (9); the protective cap opposite side has hand-held stalklet (10), and convenient protective cap (4) is a tight fit in gland (3) and meets gas face and breakdown protective cap (4).
The gland (3) of supporting hollow housing with air filter of disposable infusion set (1) and band protective cap (4) selects for use non-toxic plastic to make.The supporting internal taper tubular configured joint (8) with its hollow housing of air filter (1) garden awl end of disposable infusion set also can be made in addition the tapering point and chew shape and take over, and makes inserted sleeve when being convenient to be connected with flexible pipe.Disposable infusion set is supporting must be produced in the purification Factory Building of 100,000 grades of cleanliness factors with air filter, to guarantee product quality.
Disposable infusion set provided by the utility model is supporting simple with air filter arrangement; easy to use; there is protection cap (a 3) lid tight owing to meet the gas face at the filter disc of air filter; when transfusion operation; medicinal liquid no longer overflows air filter and is contaminated; again because the felted filter disc of having selected for use ultra-fine resin fibre to make; the effective aperture, multidimensional hole of its formation is little; when the patient accepts infusion treatment; the air that enters in the bottle is filtered purification; therefore make medicinal liquid not contaminated, guaranteed transfusion safety.
In the production process of disposable infusion set; be socketed in the supporting band internal taper tubular configured joint (8) of disposable infusion set on the needle for inserting bottle air inlet mouth of pipe of disposable infusion set with adhesive with air filter; the perfect structure function of disposable infusion set; because designed air filter sealing problem when being with protection cap (3) to solve the leakage of inspection transfusion device, medicinal liquid overflows the contaminated problem of air filter when having avoided transfusion operation.When transfusion is begun; stalklet (10) breakdown protection cap (3) on the hand-held protective cap (4) makes the air that enters in the medicine bottle all pass through felted filter disc (2) and is filtered and enters clean air chamber (7) after the purification and enter in the medicine bottle by aperture (5) and disposable infusion set air inlet pipeline, so also can guarantee patient's transfusion safety under relatively poor environmental condition.
