Abstract
The utility model provides a combined transfusion device which comprises a combined needle head, a stilligout, a regulator, a joint, a filter, a transfusion tube and a scalp needle, wherein, the upper end of the stilligout is connected with a transfusion needle in the combined needle head. The joint is connected with the scalp needle by the transfusion tube, the lower end of the stilligout is matched with the joint, and the inner part of the joint is provided with the filter. The regulator is installed on the stilligout. The utility model has the advantages of reasonable design, simple structure and easy manufacture, and uses the integral combined needle head to complete inflation, transfusion, pressurization and adding medicine. The operation is simple, and medical staff's cockamamie labor is reduced.
Description
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of combination infusion set.
Be used for clinical intravenous transfusion device at present, mostly will dispose independent air inlet pipe in addition and can use.There is following shortcoming in the intravenous transfusion device of this kind form in the middle of reality is used: one, can't pressurize in the liquid container, and narrow to the dropping speed range of accommodation that makes liquid, if need the accelerating liquid dropping speed then can't realize; Two, if in infusion process again when adding medicine in the liquid, can only puncture once more on the serum cap of liquid container mouth, it is more loaded down with trivial details so not only to operate, and is easy to pollute; Three, do not have filter at tube for transfusion and stilligout seam, when the direct vein of its seam pushes away medicine, then can't filter pushing away medicine for needing in the infusion process.Thus, the intravenous transfusion device of this kind form has brought inconvenience to every aspect clinically.
The purpose of this utility model is for overcoming above-mentioned technical deficiency part, a kind of combination infusion set is provided, and it can integrated realization air inlet, transfusion, pressurization, dosing and filtration work.
The purpose of this utility model is achieved in that the combination infusion set, comprise combination syringe needle, stilligout, actuator, joint, filter, tube for transfusion and scalp acupuncture, transfusion needle joins in the upper end of stilligout and the combination syringe needle, joint joins by tube for transfusion and scalp acupuncture, match with the inner joint that filter is housed in the lower end of stilligout, actuator is installed on the stilligout.
Advantage of the present utility model: reasonable in design, simple in structure, make easily, adopt one combination syringe needle to finish air inlet, transfusion, pressurization, dosing, simple to operate, alleviated medical personnel's loaded down with trivial details work; While is configuration filter in the tube for transfusion joint again, has avoided pushing away medicine process Chinese medicine impurity and has entered human body, has guaranteed injection quality.
Figure of description is a structural representation of the present utility model.
In conjunction with the embodiments this utility model is described in further detail below with reference to Figure of description.
Combination infusion set of the present utility model, comprise combination syringe needle (5), stilligout (7), actuator (6), joint (8), filter (9), tube for transfusion (10) and scalp acupuncture (11), the upper end of stilligout (7) joins with the middle transfusion needle (2) of combination syringe needle (5), joint (8) joins by tube for transfusion (10) and scalp acupuncture (11), match with the joint (8) that filter (9) are equipped with in inside in the lower end of stilligout (7), actuator (6) is installed on the stilligout (7).Combination syringe needle (5) is made up of transfusion needle (2), Needle with pressure-increasing means (1), three-way valve (4) and filter (3), the top of Needle with pressure-increasing means (1) is on the vertical top of transfusion needle (2), the join other end of three-way valve (4) of one end of the bottom of Needle with pressure-increasing means (1) and three-way valve (4) has air inlet (13) and inlet (12) respectively, and filter (3) is housed in the air inlet (13).
During making, process to assemble behind the various parts by above-mentioned requirements and get final product.During use, combination syringe needle of the present utility model (5) is punctured in liquid container, turn three-way valve (4) makes in its air inlet (13) and the container and communicates, and inlet (12) is then closed simultaneously, and can infuse in the usual way this moment.When need adding medicinal liquid, but turn three-way valve (4) make in its inlet (12) and the container and communicate, air inlet (13) is then closed simultaneously, the medicinal liquid of required adding is then by in inlet (12) the adding container.After dosing finishes again turn three-way valve (4) its inlet (12) and air inlet (13) are closed simultaneously, to prevent its leakage.Open the air inlet (13) of three-way valve (4) when dropping speed to be observed slows down again, make the atmospheric pressure state that keeps in the air admission container in it.If when needing to accelerate dropping speed, then exert pressure in container by the air inlet (13) of three-way valve (4) with the empty needle pipe, turn three-way valve (4) is closed inlet (12) and air inlet (13) simultaneously then.Carry out to keep the pressure in the container thus repeatedly, accelerate dropping speed.If need when the infusion process medium-sized vein injects medicine, can close actuator (6) earlier, joint (8) is unpluged from stilligout (7) lower end, the syringe port that medicine will be housed again inserts the interior pusher of joint (8) and goes into medicine, and this moment, medicine then was pushed into intravenous by joint (8), tube for transfusion (10), the scalp acupuncture (11) that filter (9) are housed.Stilligout (7) and actuator (6) are prior art.
Claims (2)
1, combination infusion set, comprise combination syringe needle (5), stilligout (7), actuator (6), joint (8), filter (9), tube for transfusion (10) and scalp acupuncture (11), it is characterized in that: the upper end of stilligout (7) joins with the middle transfusion needle (2) of combination syringe needle (5), joint (8) joins by tube for transfusion (10) and scalp acupuncture (11), match with the joint (8) that filter (9) are equipped with in inside in the lower end of stilligout (7), actuator (6) is installed on the stilligout (7).
2, combination infusion set according to claim 1, it is characterized in that: combination syringe needle (5) is made up of transfusion needle (2), Needle with pressure-increasing means (1), three-way valve (4) and filter (3), the top of Needle with pressure-increasing means (1) is on the vertical top of transfusion needle (2), the join other end of three-way valve (4) of one end of the bottom of Needle with pressure-increasing means (1) and three-way valve (4) has air inlet (13) and inlet (12) respectively, and filter (3) is housed in the air inlet (13).
