Background
The medicine adding tee is a component on the transfusion device and is used for adding medicine in the transfusion process, the medicine adding through hole is smooth and provided with a medicine adding hole, a liquid inlet through hole and a liquid outlet through hole, and a sealed medicine adding plug is arranged at the medicine adding hole. The existing dosing tee joint is mostly Y-shaped, and due to the defects of the arrangement of the dosing hole and the liquid inlet through hole, after the dosing plug is hermetically installed and connected, the end part where the liquid inlet through hole, the liquid outlet through hole and the dosing plug meet is provided with too many cavities, and the formed cavities are positioned at the end part of the dosing plug and are positioned with most parts higher than the liquid inlet through hole; therefore, bubbles are formed in the cavity and are difficult to discharge, and the gas and the bubbles in the tee joint are flushed and mixed with liquid to enter a blood circulation system of a human body, so that the health of the human body is influenced, and potential safety hazards are caused in use, and structural improvement is needed.
Disclosure of Invention
The utility model aims at solving the problems in the prior art and providing a dosing tee joint used on a transfusion device.
In order to solve the technical problem, the utility model adopts the technical scheme that: a dosing tee joint used on a transfusion device comprises a tee body, wherein the tee body is provided with a liquid inlet through hole, a liquid outlet through hole and a dosing hole which are communicated with each other, and a dosing plug is arranged in the dosing hole; the liquid outlet through hole and the medicine feeding hole are arranged on the same central axis, an included angle alpha is formed between the central axes of the liquid inlet through hole and the liquid outlet through hole, and the included angle alpha is larger than 55 degrees and smaller than 68 degrees; the end part of the liquid inlet through hole is communicated with the liquid outlet through hole, an upper junction A and a lower junction B are formed on the side wall of the liquid inlet through hole, the dosing plug comprises a sealing connecting part and a cavity eliminating part, the lower end of the cavity eliminating part extends into the liquid outlet through hole, and the lower end of the cavity eliminating part is positioned above the lower junction B.
In the above medicated tee for an infusion set, the lower end of the cavity eliminating part is planar.
In the above medicated tee for an infusion apparatus, the lower end face of the cavity eliminating part is flush with the upper intersection point A.
In the dosing tee joint for the infusion apparatus, the included angle alpha is 60 degrees.
In the dosing tee joint for the infusion apparatus, a liquid inlet platform C is arranged in the end part of the liquid inlet through hole corresponding to the lower junction B.
The utility model has the advantages that:
the utility model discloses well feed liquor through-hole, play liquid through-hole, add the position design in medicine hole to and the cooperation adds the structure installation design of medicine stopper, feed liquor through-hole, play liquid through-hole, add the cavity that medicine stopper three crossed the tip and exist in the current structure of effectual elimination, thereby effectively avoid forming here and be difficult to combustion gas bubble, gas, and then improve the security of infusion.
The liquid medicine that the feed liquor platform C got into out the liquid through-hole to the feed liquor through-hole in the utility model changes directions, and direct current offset is in a liquid through-hole lateral wall direction, further avoids at the feed liquor through-hole, goes out the liquid through-hole, adds the bubble dead angle that the end exists that intersects of medicine stopper three.
Drawings
Fig. 1 is a cross-sectional structural view of a first embodiment of the present invention;
fig. 2 is a cross-sectional structural view of a second embodiment of the present invention.
Detailed Description
The invention is further explained by combining the attached drawings.
The first embodiment is as follows:
referring to fig. 1, the utility model provides a dosing tee joint for a transfusion system, which comprises a tee body 1, wherein the tee body 1 is provided with a liquid inlet through hole 2, a liquid outlet through hole 3 and a dosing hole 4 which are communicated with each other, and a dosing plug 5 is arranged in the dosing hole 4; the liquid outlet through hole 3 and the medicine feeding hole 4 are arranged on the same central axis, an included angle alpha is formed between the central axes of the liquid inlet through hole 2 and the liquid outlet through hole 3, and the included angle alpha is larger than 55 degrees and smaller than 68 degrees; the end part of the liquid inlet through hole 2 is communicated with the liquid outlet through hole 3, an upper junction A and a lower junction B are formed on the side wall of the liquid inlet through hole, the dosing plug 5 comprises a sealing connecting part 6 and a cavity eliminating part 7, the lower end of the cavity eliminating part 7 extends into the liquid outlet through hole 3, and the lower end of the cavity eliminating part 7 is positioned above the lower junction B.
Further, a lower end portion of the cavity eliminating portion 7 is planar.
