Abstract
The utility model discloses an anti-bubble three-way base, which comprises a three-way base main body, wherein the three-way base main body comprises a straight pipe part, a branch pipe part and a liquid outlet, and the mouth parts of the straight pipe part and the branch pipe part are provided with threads; the straight pipe part of the branch pipe part is added with medicine; a step hole is formed in the position, close to the communication point, of the branch pipe, an air film is covered on the step surface of the step hole, and an air filtering cover cap is further arranged outside the step hole of the step hole. The utility model has the advantages that: simple structure is reliable, through set up the filtration mechanism in tee bend base main part, can be effectively the evacuation air in the bronchus when adding the medicine, prevents that the air from getting into the human body along with the transfer line.
Description
Technical Field
The utility model relates to a prevent bubble tee bend base belongs to medical instrument technical field.
Background
An infusion set is a common disposable medical consumable used primarily for intravenous infusion, which is aseptically processed and establishes a path between the vein and the medical fluid. 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 filter of an air inlet pipe. 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 a prevent bubble tee bend base 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 base comprises a three-way base main body, wherein the three-way base main body comprises a straight pipe part, a branch pipe part and a liquid outlet, and the mouths of the straight pipe part and the branch pipe part are provided with threads; the straight pipe part of the branch pipe part is added with medicine; a step hole is formed in the position, close to the communication point, of the branch pipe, an air film is covered on the step surface of the step hole, and an air filtering cover cap is further arranged outside the step hole of the step hole.
The branch pipe part and the straight pipe part are provided with caps in a matching way.
The diameter of the smaller hole of the stepped hole is smaller than or equal to the inner diameter of the branch pipe at the position.
And reinforcing ribs are arranged between the branch pipe parts and the straight pipe parts.
The outer side of the opening of the liquid outlet is provided with a chamfer structure.
The utility model has the advantages that: simple structure is reliable, through set up the filtration mechanism in tee bend base main part, can be effectively the evacuation air in the bronchus when adding the medicine, prevents that the air from getting into the human body along with the transfer line.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure, 1, a straight tube portion; 2. a branch pipe portion; 3. a liquid outlet; 4. a stepped bore; 5. an air filtering cap.
Detailed Description
The structural features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
The anti-bubble three-way base as shown in fig. 1 comprises a three-way base main body, wherein the three-way base main body comprises a straight pipe part 1, a branch pipe part 2 and a liquid outlet 3, and the mouth parts of the straight pipe part 1 and the branch pipe part 2 are provided with threads; the branch pipe part 2 is used for transfusion, and the straight pipe part is used for adding medicine; a step hole 4 is formed in the position, close to the communication point, of the branch pipe, an air film is covered on the step surface of the step hole 4, and an air filtering cover cap is further arranged outside the step hole of the step hole.
The branch pipe part 2 and the straight pipe part are provided with caps in a matching way.
The diameter of the smaller hole of the stepped hole 4 is smaller than or equal to the inner diameter of the branch pipe at the position.
And reinforcing ribs are arranged between the branch pipe parts 2 and the straight pipe parts 1.
The outer side of the opening part of the liquid outlet 3 is provided with a chamfer structure.
In use, air in the branch pipe part will usually gather near the intersection with the straight pipe part due to the change of the liquid flow direction of the branch pipe part communicated to the straight pipe part, and may enter the body by the flow of the liquid medicine. Thus, an air filter mechanism may be provided on the three-way base body, but if the air filter mechanism is provided elsewhere, the effect is not significant. The utility model discloses a set up near branch pipe portion and the crossing position of branch pipe portion with air filter mechanism, can be when adding the medicine, through the air in this air filter mechanism effective evacuation branch pipe, prevent that the air from getting into the human body along with the transfer line.
