Description
Technical field
this utility model relates to a kind of transfusion device, belongs to technical field of medical instruments.
Background technology
transfusion is one of the rescue of commonly using clinically and the important measures for the treatment of patient.Transfusion device forms the infusion channel between human vein and medical liquid container (transfusion bag or infusion bottle), and transfusion device is connected with scalp acupuncture, filter, flow regulator, transfusion drip tube (Murphy type burette) and bottle plug puncture unit in turn from top to bottom by infusion tube.Transfusion drip tube be for observe transfusion speed device, due to operation or position improper, in transfusion, liquid is easily filled transfusion drip tube inner chamber, cannot observe and judge the speed of transfusion; Sometimes, liquid drips off, and transfusion part position is improper, also easily makes air enter vein, causes thrombosis, crisis life.
Summary of the invention
the technical problems to be solved in the utility model is: provide a kind of transfusion reliable, transfusion device easy to use.
this utility model technical solution is: a kind of transfusion device, comprise transfusion drip tube, filter, transfusion needle, transfusion drip tube comprises the housing of sealing, the inner chamber of housing is provided with left lead and the right lead of one, between left lead and right lead, it is fluid passage, left lead inner side is provided with left gathering sill, the inner side of right lead is provided with right gathering sill, the upper end of left gathering sill and right gathering sill is the fluid inlet end of housing, the lower end of left gathering sill and right gathering sill is liquid outlet end, the end face of fluid inlet end and liquid outlet end is spherical crown end face, the cross section of left gathering sill and right gathering sill is all circular arc corresponding in opposite directions, between left gathering sill and right gathering sill, obstruction ball is housed, stop up ball and the spherical crown end face of fluid inlet end and the spherical crown end face of liquid outlet end all suitable.
as improvement, left lead and right lead are all provided with graduation mark.
above-mentioned obstruction ball, housing, left lead and right lead are transparent medical polyvinyl or vinyl polymer material.
technique effect of the present utility model is: this utility model stops up the ball vertical passage that can be provided with between left gathering sill and right gathering sill and moves up and down, and can not leave the vertical passage that left gathering sill and right gathering sill enclose.In the time that the liquid of housing inner chamber will be expired, stop up ball under the effect of liquid buoyancy, prolonging the vertical passage being provided with between left gathering sill and right gathering sill moves up, until move to the spherical crown end face of liquid outlet end, fluid inlet end is blocked, liquid no longer flows to housing inner chamber, reaches the object that stops liquid.In the time that the liquid of housing inner chamber will flow, stop up ball under the effect of gravity, prolonging the vertical passage being provided with between left gathering sill and right gathering sill moves down, until move to the spherical crown end face of liquid outlet end, liquid outlet end is blocked, and the inner chamber of the lower end tube for transfusion of liquid outlet end forms relative vacuum, and in the lower end of liquid outlet end, infusion tube retains certain liquid, be unlikely to air and enter intravenous, reach and prevent that air from entering the object of vein.Left lead and right lead are all provided with graduation mark, are convenient to observe the height that stops up ball.Therefore, the utlity model has transfusion reliably, easy to use, the feature of novel structure.

Detailed description of the invention
describe in detail below in conjunction with drawings and Examples:
as Fig. 1 to Fig. 6, and shown in Fig. 9, a kind of transfusion device of this utility model, comprise transfusion drip tube 5, filter 4, transfusion needle 1, transfusion drip tube 5 comprises the housing 6 of sealing, the inner chamber of housing 6 is provided with left lead 7 and the right lead 8 of one, left lead 7 and right lead 8 longitudinally between be fluid passage, left lead 7 inner sides are provided with left gathering sill 13, the inner side of right lead 8 is provided with right gathering sill 14, the fluid inlet end 10 that the upper end of left gathering sill 13 and right gathering sill 14 is housing, the lower end of left gathering sill 13 and right gathering sill 14 is liquid outlet end 11, the end face of fluid inlet end 10 and liquid outlet end 11 is spherical crown end face, the cross section of left gathering sill 13 and right gathering sill 14 is all circular arc corresponding in opposite directions, between left gathering sill 13 and right gathering sill 14, be equipped with and stop up ball 9, stop up ball 9 all suitable with the spherical crown end face of fluid inlet end 10 and the spherical crown end face of liquid outlet end 11, stop up the vertical passage 3 surrounding between ball 9 and left gathering sill 13 and right gathering sill 14 suitable.Left lead 7 and right lead 8 are all provided with graduation mark 15.Stopping up ball 9, housing 6, left lead 7 and right lead 8 is transparent medical polyvinyl or vinyl polymer material.
