Abstract
The utility model discloses precision filtrating and bubble-preventing infusion apparatus. A dropper (2) is connected to the upper end of a dropping funnel (1) while a flexible pipe (14) is connected to the bottom end of the dropping funnel (1); a flow regulator (13) is arranged on the flexible pipe (14); the flow regulator (13) is connected to one end of an infusion needle tube (10) while an infusion needle point handle (9), an infusion needle point (8) and an infusion needle point protective sleeve (7) are connected to the other end thereof; a bubble-preventing dropper (15) is mounted at the lower end inside the dropping funnel (1); and the bubble-preventing dropper (15) is communicated with the flexible pipe (14). The infusion apparatus provided by the utility model can prevent human body from being threatened by massive particles, can run freely during the infusion process for patients, and has very simple structure and process, easy implementation, convenient operation and safety.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of high-accuracy medical filtration bubble-proof transfusion device specifically.
Background technology
Some used in the market transfusion devices all are general infusion sets, though economic and practical, it is exactly that its filtering microgranule rejection rate of liquid medicine filter is not high that a shortcoming is arranged, and bubble can not be stopped fully.
Summary of the invention
The purpose of this utility model provides a kind of secondary filter bubble-proof transfusion device that can effectively stop the generation of bubble.
The secondary filter bubble-proof transfusion device that this utility model provides; the dropping funnel upper end is connected to dropper; the inside, bottom is connected to flexible pipe; be connected to flow regulator on the flexible pipe; infusion needle tubing one termination flow regulator; the other end is connected to transfusion needle point handle, transfusion needle point and transfusion needle point protective sleeve, and lower end, dropping funnel the inside is equipped with anti-bubble dropper, and anti-bubble dropper and flexible pipe are connected.
Anti-bubble dropper end sealing, the side has the gas-tight side channel at interval.
On the infusion needle tubing, be connected to a filter, be filled with nucleopore membranes in this filter.
The aperture of described nucleopore membranes is below 3 microns.
Anti-bubble dropper is longer than the length that dropper stretches into the dropping funnel inner end.
The beneficial effects of the utility model: in the process of transfusion, can prevent the threat that a large amount of microgranules causes human body, and patient can be free movable in the process of transfusion, its structure and technology are all special simple, also easily implement, and is easy to operate, safety.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
The secondary filter fat bubble transfusion device that this utility model provides, dropping funnel 1 upper end is connected to dropper 2, and dropper 2 is a tee T; dropper 2 one interfaces stretch into the dropping funnel the inside, and in two interfaces, wherein an interface is a liquid injection port 3 in addition; another interface connects puncture outfit 5 by handle 4, and is set with puncture outfit protective sleeve 6.Lower end, dropping funnel 1 the inside is equipped with anti-bubble dropper 15; the length that stretches into dropping funnel 1 inner end than dropper is long; anti-bubble dropper 15 end sealings; the side has three gas-tight side channels 16 at interval; long 15mm; wide 2mm; the flexible pipe 14 of anti-bubble dropper 15 lower ends and dropping funnel 1 bottom is connected; flow regulator 13 is arranged on flexible pipe 14; the infusion needle tubing 10 of flow regulator 13 through being connected to a filter 11 connects transfusion needle point handle 9, transfusion needle point 8 and transfusion needle point protective sleeve 7 again; this filter is filled with nucleopore membranes 12 for 11 li, and the aperture of nucleopore membranes 12 is below 3 microns.
And dropping funnel 1 has anti-bubble dropper 15, earlier dropping funnel is hung upside down into conduit during operation, medicinal liquid enters dropping funnel from bottom to top, air is upwards discharged, and medicinal liquid enters downcomer after being raised to anti-foam tube inlet again, and remaining gas is enclosed in the dropping funnel, dropping funnel restores down to be hung, remaining gas rises, and liquid infra, air just can't enter conduit.
