Abstract
The utility model discloses an anti-bubble three-way injection piece, which comprises a three-way base, wherein the three-way base comprises a straight pipe part and a branch pipe part; the upper end of the straight pipe part is closed, and the lower end of the straight pipe part is a liquid outlet; the side wall of the upper part of the straight pipe part is at least provided with a connecting channel communicated with the inner cavity of the straight pipe part; one end of the branch pipe part is connected with the straight pipe part; the other end is a liquid inlet; and the position where the branch pipe part is connected with the straight pipe part is upwards provided with an ascending channel along the outer wall of the straight pipe part and is communicated with the inner cavity of the straight pipe part through the connecting channel. The utility model has the advantages that: the structure is simple and reliable, and the air in the branch pipe can be effectively emptied when the medicine is added through the special design of the ascending channel and the connecting channel of the three-way base, so that the air is prevented from entering the human body along with the liquid medicine.
Description
Technical Field
The utility model relates to an injection piece specifically is a prevent bubble tee bend injection piece, belongs to medical instrument technical field.
Background
An infusion set is a common disposable medical consumable used mainly for intravenous infusion and used for establishing a channel between a vein and liquid medicine after sterile treatment. The infusion apparatus is generally composed of a vein needle, a protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip cup, a bottle stopper puncture outfit and an air inlet pipe air filter which are connected. At present, in the operation process, an infusion apparatus used when a doctor establishes a venous channel for a patient is composed of a common precise infusion apparatus, one or more three-way valves and a corresponding number of three-way extension pipes.
The existing three-way of the infusion apparatus consists of two parts, namely a three-way plastic part and a rubber part. One part of the structure is that a rubber part is directly covered on a third port of the tee joint, and the structure has the defect that when the straight pipe is used for adding medicine, air in the straight pipe is extruded into the infusion tube and then enters a human body.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an anti-bubble tee bend injection spare to solve prior art's above-mentioned technical problem.
The purpose of the utility model is realized by the following technical scheme.
An anti-bubble three-way injection piece comprises a three-way base, wherein the three-way base comprises a straight pipe part and a branch pipe part; the upper end of the straight pipe part is closed, and the lower end of the straight pipe part is a liquid outlet; the side wall of the upper part of the straight pipe part is at least provided with a connecting channel communicated with the inner cavity of the straight pipe part; one end of the branch pipe part is connected with the straight pipe part; the other end is a liquid inlet; and the position where the branch pipe part is connected with the straight pipe part is upwards provided with an ascending channel along the outer wall of the straight pipe part and is communicated with the inner cavity of the straight pipe part through the connecting channel.
The outer side of the liquid outlet is provided with a circle of connecting part with internal threads for connecting with an injection needle or a transfusion tube.
The straight pipe part is closed by an air filtering cap.
The liquid inlet of the branch pipe part is higher than the joint of the branch pipe part and the straight pipe part.
And a reinforcing rib is arranged between the branch pipe part and the straight pipe part.
The utility model discloses in, the liquid medicine flows in through the branch pipe portion of slope, wraps up in the air and arrives branch pipe portion outer wall and, the liquid medicine upwards reachs interface channel department along ascending passageway, flows in from straight tube portion promptly soon, and the bubble is taken the top of straight tube portion and is gathered in straight tube portion top by the liquid stream this moment, or adsorbs on the filtration block with the bubble form. Thereby avoiding the liquid medicine from being wrapped with bubbles.
The utility model has the advantages that: the structure is simple and reliable, and the air in the branch pipe can be effectively emptied when the medicine is added through the special design of the ascending channel and the connecting channel of the three-way base, so that the air is prevented from entering the human body along with the liquid medicine.

In the figure, 1, a straight tube portion; 2. a branch pipe portion; 3. an air filtration cap; 4. an upstream channel; 5. a connecting channel; 6. a connecting portion.
Detailed Description
The structural features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
An anti-bubble three-way injection member as shown in fig. 1 comprises a three-way base, wherein the three-way base comprises a straight pipe part and a branch pipe part; the upper end of the straight pipe part is closed, and the lower end of the straight pipe part is a liquid outlet; the side wall of the upper part of the straight pipe part is at least provided with a connecting channel communicated with the inner cavity of the straight pipe part; one end of the branch pipe part is connected with the straight pipe part; the other end is a liquid inlet; and the position where the branch pipe part is connected with the straight pipe part is upwards provided with an ascending channel along the outer wall of the straight pipe part and is communicated with the inner cavity of the straight pipe part through the connecting channel.
The outer side of the liquid outlet is provided with a circle of connecting part with internal threads for connecting with an injection needle or a transfusion tube.
The straight pipe part is closed by an air filtering cap.
The liquid inlet of the branch pipe part is higher than the joint of the branch pipe part and the straight pipe part.
The utility model discloses in, the liquid medicine flows in through the branch pipe portion of slope, wraps up in the air and arrives branch pipe portion outer wall and, the liquid medicine upwards reachs interface channel department along ascending passageway, flows in from straight tube portion promptly soon, and the bubble is taken the top of straight tube portion and is gathered in straight tube portion top by the liquid stream this moment, or adsorbs on the filtration block with the bubble form. Thereby avoiding the liquid medicine from being wrapped with bubbles.
The above examples only show several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention.
