Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, right below in conjunction with attached drawing of the present inventionTechnical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of the inventionEmbodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making woundEvery other embodiment obtained under the premise of the property made labour, shall fall within the protection scope of the present invention.
Referring to Fig.1-2, a kind of dosing part being used cooperatively with transfusion instrument, which includes dosing shell 1, dosing shellDosing chamber 2 is provided in body 1, the top of dosing chamber 2 is provided with dosing mouth and the dosing pad 3 for sealing dosing mouth, dosing chamber 2Bottom be equipped with liquid outlet 8 for being connected to transfusion instrument；The side of the dosing shell 1 is vertically provided with counter-flow vat 5, inverseThe top of chute 5 is connected to dosing mouth, and the dosing tank 4 cooperated with counter-flow vat 5 is provided on dosing pad 3；The bottom of the counter-flow vat 5Portion is communicated with the feed pathway 6 for tilting upward setting, and feed pathway 6 is equipped with the inlet 7 for being connected to transfusion instrument.It is inverseThe setting of chute 5 can make medical fluid full of entire dosing chamber 2, avoid trapped air, air is with medical fluid caused by having prevented because of dosingThe case where into human vein；Principle is that medical fluid from inlet 7 enters dosing part, is flowed up by counter-flow vat 5, then from addingIt is flowed into dosing chamber 2 at medicine mouth, and is full of entire dosing chamber 2, finally flowed out from liquid outlet 8, ensure that normal infusion；It needs to addWhen medicine, dosing pad 3 is opened, it can be convenient and efficient by dosing mouth dosing into dosing chamber 2.
The mounting groove cooperated with dosing pad 3 is provided at the dosing mouth, the bottom of mounting groove, which is equipped with, is used to support dosingThe installation land of pad 3, the top of mounting groove are equipped with the ring edge for fixing dosing pad 3.Installation land is for holding dosing pad 3Bottom, ring avoid falling after dosing pad 3 is put into mounting groove along the top for blocking dosing pad 3.
The dosing pad 3 is cylindrical, the spatially fan shape of dosing tank 4.Dosing tank 4 is setting in 3 bottoms one of dosing padThe groove of side, so that medical fluid flows into dosing chamber 2 from the top of dosing chamber 2, dosing chamber 2 is full of convenient for cooperating with counter-flow vat 5,Avoid retaining for air.
The length of the counter-flow vat 5 is the 1/3-1/2 of the length of dosing chamber 2；Preferably, the length of the counter-flow vat 5 isThe 1/3 of the length of dosing chamber 2 flows into dosing chamber 2 from counter-flow vat 5 convenient for medical fluid, avoids the too long pressure of counter-flow vat 5 larger, influencesNormal infusion.
The angle of angle between the feed pathway 6 and counter-flow vat 5 is 45 ° -60 °；Preferably, the feed pathway 6The angle of angle between counter-flow vat 5 is 45 °.The top of feed pathway 6 is arranged in inlet 7, convenient for connecting with transfusion instrumentIt connects and medical fluid is inputted into dosing chamber 2.
The dosing part is in addition to dosing pad 3, generally integrally formed moulding, convenient for being mass produced, and meanwhile it is airtightProperty is good, can guarantee normal infusion.
