Abstract

The utility model discloses a three-way pipe for injection which comprises a pipe body on which is provided with a primary inlet, a side inlet and an outlet. Among the primary inlet, the side inlet and the outlet are provided with a valve inside which is set with a passage. The reversing extension line of the primary inlet, the side inlet and the outlet are arranged symmetrically, and the included angle symmetrically set between two passages are consistent with that of between the primary inlet and the side inlet. When medicine is given to the patient by adopting the utility model, the pipe is smooth, in particular to giving medicine by using the microinjection pump. Within the specified time, the dose is easy to control and easy to be regulated on a stable data level. The utility model can be used as a medical device and put through two interventional sacculuses.

Description

The transfusion tee T

Technical field this utility model relates to the apparatus to patient infusion treatment usefulness, directly relates to the tee T that infusion treatment is used.

Be everlasting when background technology is carried out infusion treatment in hospitals at different levels to patient and tee T be set in the pipeline.Its main-inlet of existing tee T, outlet are in alignment, side entrance and main-inlet, export vertical setting, the T font, the side entrance is positioned at the below of T font.Medicine flows to outlet from main-inlet during treatment, flows in the patient body again, as needing dosing, can enter by the side entrance in the middle of the treatment.Yet the tee T of this structure is because side entrance and main-inlet, Way out are vertical, be subjected to main-inlet medicinal liquid pressure influence, can produce the administration resistance in the side entrance, sometimes in addition the administration meeting be suppressed, especially when using the micro pump drug treatment, because the seance administration time generally will continue more than 24 hours, and advance prescription bit time dosage and require very for a short time again, therefore be difficult to the dosage in the unit interval is adjusted to suitable stable data level.

The summary of the invention the purpose of this utility model will provide a kind of improved transfusion tee T exactly, and it can overcome the drawback that existing transfusion causes because of side entrance and main-inlet, the vertical administration resistance that causes of Way out with tee T effectively.

The purpose of this utility model is to realize like this, the transfusion tee T, has body, main-inlet, side entrance and outlet are arranged on the body, between main-inlet, side entrance and the outlet valve is set, passage is set in the valve, it is characterized in that: the reverse extending line symmetric arrangement of main-inlet, side entrance and outlet, and the angle between main-inlet and the side entrance is less than 120 °; The reverse extending line symmetric arrangement at two road junctions of passage and the 3rd road junction, and the angle between two road junctions of symmetric arrangement is consistent with the angle between main-inlet, the side entrance.

As further scheme of the present utility model, be that angle between described main-inlet and the side entrance is less than 90 °.

This utility model is because the reverse extending line symmetric arrangement of main-inlet, side entrance and outlet, and the angle between main-inlet, side entrance has adopted the structure less than 120 °, thereby when adopting this utility model transfusion to give patient's dosing by the side entrance with tee T, pipeline is comparatively unimpeded, especially when using the micro pump drug treatment, unit interval innerlich anwenden dosage control is conveniently also adjusted to the stable data level easily.

Description of drawings Fig. 1 is this utility model transfusion structural representation when realizing threeway with tee T, Fig. 2 is this utility model transfusion structural representation when opening with tee T primary input pipeline, and Fig. 3 is infuse a structural representation when opening with tee T side input channel of this utility model.The utility model is described in further detail below in conjunction with accompanying drawing.

Specific embodiment Fig. 1 shows this utility model transfusion structure of tee T under the threeway state, main-inlet 3, side entrance 1 are set on the body 4 and export 6, main-inlet 3, side entrance 1 and export 6 between valve 5 is set, passage 2 is set in the valve 5, main-inlet 3, side entrance 1 and the reverse extending line symmetric arrangement that exports 6, and the angle between main-inlet 3 and the side entrance 1 is less than 120 °, and preferred version is less than 90 °, first-selected 60 ° or 45 °.The reverse extending line symmetric arrangement at two road junctions of passage 2 and the 3rd road junction, and the angle between two road junctions of symmetric arrangement is consistent with the angle between main-inlet 3, the side entrance 1.Under this state, can be in routine transfusion, by side entrance 1 dosing or use the micro pump administration.

Fig. 2 shows the structure of this utility model transfusion with tee T primary input pipeline opening state, main-inlet 3, side entrance 1, the fixed-site of outlet 6 on body 4 are constant, valve 5 rotates to an angle with respect to body 4, make on the valve 5 passage 2 only with main-inlet 3, outlet 6 UNICOMs, enter conventional transfusion state this moment.

Fig. 3 shows the structure of this utility model transfusion with tee T side input channel opening state, main-inlet 3, side entrance 1, the fixed-site of outlet 6 on body 4 are constant, valve 5 rotates to an angle with respect to body 4, make on the valve 5 passage 2 only with side entrance 1, outlet 6 UNICOMs, can realize changing medication infusion this moment by side entrance 1.

Tee T is used in this utility model transfusion, after valve 5 rotates to an angle again, and passage 2 and outlet 6 staggered positions, valve 5 is closed, and this utility model quits work.

Main-inlet 3 described in this utility model, side entrance 1 have interchangeability, can select arbitrarily before enabling.

This utility model also can be used as the apparatus of interventional therapy, and main-inlet 3, side entrance 1 linked and can realize with the intervention sacculus separately as long as outlet 6 directly links with compression pump this moment.

Claims

1, a kind of transfusion tee T, has body (4), main-inlet (3), side entrance (1) and outlet (6) are arranged on the body (4), between main-inlet (3), side entrance (1) and the outlet (6) valve (5) is set, passage (2) is set in the valve (5), it is characterized in that: main-inlet (3), side entrance (1) and the reverse extending line symmetric arrangement that exports (6), and the angle between main-inlet (3) and side entrance (1) is less than 120 °; The reverse extending line symmetric arrangement at two road junctions of passage (2) and the 3rd road junction, and the angle between two road junctions of symmetric arrangement is consistent with the angle between main-inlet (3), side entrance (1).

2, transfusion tee T according to claim 1 is characterized in that: the angle between described main-inlet (3) and side entrance (1) is less than 90 °.
