Abstract
The utility model relates to a medical appliance, in particular to a filtering tee joint for transfusion. The filtering tee joint comprises a tee joint body and a control valve; the liquid outlet of the tee joint body is provided with an automatic exhausting filter; the liquid cleaning mouth of the filter is provided with an interface connected with a transfusion needle. The filtering tee joint organically combines with a common tee joint for transfusion with the liquid filter, thereby does not only avoiding the tiny air bubbles attached at inner wall of the tee joint body or the inner wall of a transfusion pipeline from entering into a human body, but also solving the problem that the tiny granules enters into the human body when the medicine is directly injected from the liquid inlet of the tee joint body. The filtering tee joint greatly improves the safety of treatment by transfusion.
Description
Technical field:
This utility model relates to medical apparatus and instruments, and especially a kind of transfusion is with filtering threeway.
Background technology:
At present, clinical transfusion often uses threeway, so that through the administration simultaneously of an infusion needle two-way.Existing threeway is made of three-way body and control valve, and three-way body has two feed liquor interfaces and one to go out liquid interface.When using this threeway to infuse, often because of aerofluxus preparation deficiency, the small air bubble that three-way body inwall or infusion pipeline inwall are adhered to enters human body, perhaps when the direct injection liquid of three-way body feed liquor interface, there is molecule to enter human body, causes certain injury to the patient.Chinese patent ZL00213809.3 discloses a kind of transfusion and has filtered threeway with connecting medicated cap, and it has only solved through the direct injection liquid of three-way body feed liquor interface avoids molecule to enter the problem of human body.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of follow-on transfusion with filtering threeway, to overcome the described disadvantage because of using threeway to infuse and bring to the patient of above-mentioned background technology.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of transfusion comprises three-way body, control valve with filtering threeway, and this three-way body liquid outlet is equipped with the automatic vent filter, and the clean liquid mouth of this filter is provided with the interface that is connected with infusion needle.
Compared with prior art, the beneficial effects of the utility model are: it is integral common transfusion with threeway and liquid filter organic assembling, the possibility that the small air bubble of both having avoided three-way body inwall or infusion pipeline inwall to adhere to enters human body, solved again when the direct injection liquid of three-way body feed liquor interface, the problem that has molecule to enter human body, the safety when greatly having improved infusion treatment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of transfusion is with filtering threeway, constitute by three-way body 1, control valve 2, filter 3, infusion needle interface 4, this three-way body 1 is provided with 6,7 and fluid mouths of pipe 5 of two feed liquor mouths of pipe, control valve 2 is installed in its centre, to adjust or to close the feed liquor mouth of pipe 6,7,5 ones of its fluid mouths of pipe are equipped with a filter 3 with automatic vent function, and the clean liquid export department of this filter 3 is provided with infusion needle interface 4.Can be one-body molded when above-mentioned three-way body 1, control valve 2, filter 3,4 making of infusion needle interface, constitute overall structure.
