Embodiment 1

[0022] see figure 1 , figure 1 The X-axis of the coordinate system in and other figures is the horizontal axis, and the Y-axis is the vertical axis of gravity. The adsorbent capacity filled in the adsorption column is 130 milliliters. The blood purifier 1 is connected to the pipeline through the blood nozzle, and the pipeline close to the inlet of the adsorption column is connected to the solution source. When the solution reaches the pipeline port connected to the inlet port of the blood purifier, the power source is cut off, and the pipeline is respectively connected to the inlet port 11 and the outlet port 12 of the blood purifier 1, wherein the pipeline connected to the outlet port 12 may not Perform pre-exhaust, then restart the power source, and when the solution is injected into the blood purifier and enters the outlet port 12 pipeline, start the exhaust operation of the present invention, wherein the flow rate of the solution is 200 ml / min. The specific exhaust meth...

Embodiment 2

[0031] Only the differences from Embodiment 1 will be described below, and the similarities will not be repeated.

[0032] Step 1: The tapping force F1=5 Newton.

[0033] Step 3: The included angle θ=20°, the tapping force F3=5 Newton.

[0034] In this example, the time required to exhaust the gas in the blood purifier is 62.0 seconds.

Embodiment 3

[0036] Only the differences from Embodiment 1 will be described below.

[0037] Step 1: The tapping force F1=15 Newton.

[0038] Step 3: The included angle θ=15°, the tapping force F3=15 Newton.

[0039] In this example, the time required to exhaust the gas in the blood purifier is 27.0 seconds.

Abstract

The invention relates to a blood purifier exhaust method; a suitable blood purifier comprises an adsorption column filled with an adsorbent, and a filter net and a blood port arranged on an inlet end and outlet end of the adsorption column; the blood port on the inlet end is connected with aqueous solution through a tube; the exhaust method comprises the following steps: 1, placing the blood purifier in a mode in which the axis is in a horizontal position, and knocking the housing on the inlet end side of the blood purifier so as to fully exhaust air bubbles on the inlet end; 2, rotating the blood purifier so as to allow the axis in a plumb position, allowing the outlet end on the top and the inlet end on the bottom, knocking the housing on the outlet end side of the blood purifier so as to exhaust most air bubbles on the filter net of the outlet end; 3, rotating the blood purifier so as to form a [theta] angle between the axis and the horizontal plane, allowing the outlet end to be higher than the inlet end, and knocking the upper housing on the inlet end side of the blood purifier so as to fully exhaust the air bubbles in the outlet end, wherein 0<[theta]<=60 degrees. The method is fast in exhausting, and saves laboring.

Description

technical field [0001] The invention relates to a method for using a medical device, in particular to a method for exhausting a blood purifier. Background technique [0002] Hemoperfusion is an important part of blood purification therapy. It is to draw the patient's blood out of the body, and make this part of the blood contact with the adsorbent in the blood purifier, remove some exogenous or endogenous toxins by adsorption, and The purified blood is transfused back into the patient's body, so as to achieve the therapeutic purpose of purifying the blood. Hemoperfusion can be used not only to treat severe poisoning and drug poisoning, but also to treat many chronic, intractable and intractable diseases, all of which have good therapeutic effects and are widely used in clinical treatment. [0003] The blood purifier is filled with blood purification consumables as adsorbents, such as disposable hemoperfusion devices, disposable endotoxin adsorbers, disposable plasma bilirub...
