Abstract
The invention discloses a bubble prevention three-way structure used for a disposable infusion apparatus. The bubble prevention three-way structure comprises a three-way pipe fitting body. The three-way pipe fitting body comprises a main pipe connected with an infusion hose, an infusion branch pipe connected with the infusion hose, and a medicine adding branch pipe. The infusion branch pipe is arranged into a V-shaped structure. One port of the infusion branch pipe is connected with the infusion hose, and the other port of the infusion branch pipe is formed in the opening part of the medicine adding branch pipe or close to the opening part of the medicine adding branch pipe. A sealing cover is arranged at the opening part of the medicine adding branch pipe. The bubble prevention three-way structure has the following advantages that due to the new structure, a continuous infusion channel is formed by the infusion branch pipe and the main pipe, it is avoided that air is left in the medicine adding branch pipe, and it is also avoided that air enters human bodies and the danger of aeroembolism is caused; due to the V-shaped design of the infusion branch pipe, the joint of the infusion branch pipe and the main pipe is lifted, and therefore during infusion, liquid medicine can have a certain speed under the effect of gravity, liquid medicine forms upward impacting force when entering the three-way structure, and air in the medicine adding branch pipe is discharged to be maximum extent before infusion.
Description
Technical field
The present invention relates to a kind of three-port structure of disposable transfusion device, be specially disposable transfusion device Anti-bubble three-port structure, belong to technical field of medical instruments.
Background technology
A kind of be mainly used in venous transfusion through aseptic process, the common disposable medical treatment consumptive materials of setting up passage between vein and medicinal liquid.Generally connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle, bottle plug puncture unit, air inlet pipe air filter.The sterilization effect duration of medical worker's preoperation inspection disposable transfusion device and packaging are with or without gas leakage and other exceptions, take out transfusion device, by cone joint partial insertion infusion bottle, hang infusion bottle on transfusion pole, be vented to medicinal liquid and flow to tube for transfusion lower end, fasten actuator, again intravenous needle is thrust the vein disinfected, after fixing, untie tourniquet, adjustment flow velocity.In order to add other medicinal liquids when infusing, on tube for transfusion, be generally provided with " y " type three-port structure, one of them of two arms is tube for transfusion, and another arm is chemical feed pipe.During dosing, by syringe, injecting liquid drug is entered tube for transfusion.But, the top that the tube for transfusion of three-port structure and chemical feed pipe intersect also has one section of chemical feed pipe cavity, such design can cause occurring that air column 13 (as shown in Figure 1) is when adding medicinal liquid above the tube for transfusion 11 and chemical feed pipe 12 intersection of three-port structure, air can be brought into human body by medicinal liquid in the lump, causes aeroembolism risk.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of disposable transfusion device Anti-bubble three-port structure, to solve the problems referred to above of prior art.
Object of the present invention can be achieved through the following technical solutions.
Disposable transfusion device Anti-bubble three-port structure, comprises tee pipe fitting main body, and described tee pipe fitting main body comprises: connect the supervisor of infusion tube, the transfusion arm connecting infusion tube and dosing arm; Described transfusion arm is set to " V " font structure, and transfusion arm Single port is connected with infusion tube, and another port is arranged at the oral area of dosing arm or the oral area close to dosing arm; Described dosing is propped up spout part and is also arranged a seal cover.
The dosing mouth distance of described transfusion arm and the junction point of dosing arm and dosing arm is less than or equal to 5mm.
Described tee pipe fitting main body is skew T pipe fitting, and wherein, oblique arm is transfusion arm, and allotment pipe is dosing arm.
" V " font structure of transfusion arm is unsymmetric structure, and the side branch be connected with infusion tube is longer.
Technical solution of the present invention has following beneficial effect:
1, new construction will be infused arm and supervisor's formation one continuous transfusion passage, avoid air and will take at dosing arm place, it also avoid air and enter human body, cause aeroembolism dangerous;
2, the transfusion arms run of V-shape, transfusion arm is raised up with supervisor junction, when making transfusion, medicinal liquid has certain speed under gravity, impulse force is upwards formed like this when medicinal liquid enters three-port structure, medicinal liquid can arrive any position (comprising top) of dosing arm, can be got rid of by the air in dosing arm to greatest extent before transfusion.

In figure, arrow dotted line represents the flow direction of medicinal liquid.
Detailed description of the invention
Construction features of the present invention is set forth further below in conjunction with specific embodiment.
The Anti-bubble three-port structure of disposable transfusion device as shown in Figure 1, comprises tee pipe fitting main body, and described tee pipe fitting main body comprises: connect the supervisor 23 of infusion tube, the transfusion arm 21 connecting infusion tube and dosing arm 22; Described transfusion arm 21 is set to " V " font structure, transfusion arm 21 Single port is connected with infusion tube, and another port is arranged at the oral area of dosing arm 22; Described dosing arm 22 oral area also arranges a seal cover 24.
Dosing mouth 25 distance of described transfusion arm 21 and the junction point of dosing arm 22 and dosing arm 22 is less than or equal to 5mm.
Described tee pipe fitting main body is skew T pipe fitting, and wherein, oblique arm is transfusion arm 21, and allotment pipe is dosing arm 22.
" V " font structure of transfusion arm 21 is unsymmetric structure, and the side branch be connected with infusion tube is longer.
During use, respectively transfusion arm 21 is connected the infusion tube of transfusion device with supervisor 23.Before transfusion, get rid of the air in transfusion device, when medicinal liquid is by tee pipe fitting main body, V-shape transfusion arm 21 structure makes medicinal liquid flow into dosing arm 22 and supervisor 23 with certain speed; Thus all take the air in dosing arm 22 out of transfusion device.Avoid air and enter human body and the danger brought.
