Abstract

The invention discloses an integrated infusion apparatus with a drop-weight control head disposed inside. The integrated infusion apparatus comprises a liquid drop bottle puncture needle, an upper drop pipe, the drop-weight control head, a drop bucket, a lower drop pipe, a drop speed controller, a filter and a needle head, the upper drop pipe, the drop bucket and the lower drop pipe are integrally formed by adopting processes like extrusion molding, the drop-weight control head is arranged at an upper opening in the drop bucket and provided with an up-down-through inner hole, an arc-shaped liquid drop face is arranged at the lower end of the drop-weight control head, an annular groove is arranged on the upper portion of the drop-weight control head, and the pipe wall of the upper opening of the drop bucket is inwards provided with an annular flange. When being compressed, the drop-weight control head resiles by placing the upper drop pipe or the lower drop pipe at the upper opening in the drop bucket, the groove of the drop-weight control head is enabled to be closely connected on the annular flange of the drop bucket in an expanded manner, and the drop-weight control head is fixed at the upper opening in the drop bucket. By the integrated infusion apparatus, liquid drop weight can be controlled, manufacturing cost can be lowered, and manufacturing process is simple.

Description

A kind of integrated infusion device of built-in heavy control head
Technical field
The present invention relates to orthopedic medical device field.
Background technology
At present, the transfusion device that used clinically, generally formed by Liquid dropping bottle puncture needle, upper dropper, dropping funnel, lower dropper, a fast controller, filter, syringe needle etc., heavy control head is dripped in being also provided with of having, the installation of described heavy control head, connects as one a heavy control head, dropping funnel, upper conduit, downcomer respectively by bonding, and such manufacturing process operation is many, manufacturing cost is high, and adhesive portion easily produces gas leak phenomenon.
Summary of the invention
The invention discloses a kind of integrated infusion device of built-in heavy control head, overcome above-mentioned defect, it comprises Liquid dropping bottle puncture needle, upper dropper, drip heavy control head, dropping funnel, lower dropper, drip fast controller, filter, syringe needle, described upper dropper, dropping funnel, lower dropper can adopt the technique one-shot formings such as extrusion molding to be integrated, eliminate the defect of bonding gas leakage, described heavy control head is located at suitable for reading in dropping funnel, described heavy control head is provided with and connects upper and lower endoporus, its lower end is provided with arc dropping liquid face, it is characterized in that described top of dripping heavy control head is provided with annular groove, the tube wall suitable for reading of described dropping funnel is inwardly provided with annular flange flange, after described heavy control head compression, put to the place suitable for reading in described dropping funnel and resile by upper dropper or lower dropper, make the described groove that drips heavy control head closely expanded joint in the annular flange flange of described dropping funnel, be fixed on suitable for reading in described dropping funnel by dripping heavy control head.The integrated infusion device of this built-in heavy control head, manufacturing process is simple, both can strictly control the weight of dropping liquid, can effectively reduce again manufacturing cost, and has eliminated the defect of bonding gas leakage.
