Abstract
The utility model relates to a medical device, in particular to an infusion device, which comprises an infusion pipe, a puncture needle and a T joint which are respectively arranged on the two ends of the infusion pipe, and a buffering chamber which is in series connection with the infusion pipe. An air filter is arranged on the T joint. A liquid filter is in series connection with the infusion pipe between the buffering chamber and the puncture needle. Two layers of liquid filters are arranged on the infusion pipe, thus the filtering effect is good. Moreover, as the first layer liquid filter is arranged before the buffering chamber, the flow of the liquid is not influenced.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of transfusion device.
Technical background
Existing Dispoable medical transfusion device enters human body in order to prevent the impurity in air pollution and the medicinal liquid, harm patient's health, air filter and liquid filter all are installed on transfusion device, and liquid filter is installed in series on the tube for transfusion between surge chamber and puncture needle.This transfusion device has only one deck liquid filtering usually, and poor filtration effect makes liquid flowing resistance become big again if the multiple filtration device is installed, and influence is normally used.
Summary of the invention
The purpose of this utility model provides a kind of good filtration effect, does not influence the double filtration transfusion device of normal use.
For achieving the above object, this utility model adopts following technical scheme:
A kind of double filtration transfusion device described in the utility model comprise tube for transfusion, respectively be installed in the tube for transfusion two ends puncture needle and threeway, be connected on surge chamber and speed setting controller on the tube for transfusion, have air filter in the threeway, be in series with liquid filter on the tube for transfusion between surge chamber and the puncture needle, on the tube for transfusion between threeway and the surge chamber, be in series with liquid filter.
On the tube for transfusion two-layer liquid filter is installed after the employing technique scheme, good filtration effect, and the ground floor liquid filter does not influence flowing of liquid in the front of surge chamber.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the present utility model.
Specific embodiment
As shown in drawings, a kind of double filtration transfusion device described in the utility model comprise tube for transfusion 1, respectively be installed in tube for transfusion 1 two ends puncture needle 2 and threeway 3, be connected on surge chamber 5 and speed setting controller 8 on the tube for transfusion 1, have air filter 4 in the threeway 3, be in series with liquid filter 6 on the tube for transfusion 1 between surge chamber 5 and the puncture needle 2, on the tube for transfusion 1 between threeway 3 and the surge chamber 5, also be in series with liquid filter 7.
