Abstract
Description
Technical Field
[0001] This utility model relates to the field of adsorbent filling measurement technology for perfusion devices, and in particular to a blood perfusion device adsorbent filling volume detector. Background Technology
[0002] In the biotechnology blood perfusion device industry, the filling volume and precision of the adsorbent are key factors affecting product quality.
[0003] However, traditional measurement methods have many shortcomings due to the fact that adsorbent particles are prone to floating and bridging and have long settling times. For example, pouring wet resin into a graduated cylinder for long-term static sedimentation measurement not only takes a long time but also cannot accurately measure the volume. Furthermore, due to the differences in adsorbent density and packing density, the static sedimentation time is inconsistent, resulting in unstable measurement data. Utility Model Content
[0004] This invention presents a blood perfusion adsorbent filling volume detector, which solves the existing problems.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a blood perfusion device adsorbent filling volume detector, comprising:
[0006] A measuring cylinder, wherein a hollow groove is provided inside the measuring cylinder, and the measuring cylinder is used to load adsorbent particles mixed with liquid;
[0007] The compaction scale column is connected to the inside of the measuring cylinder, and a through groove is opened inside the compaction scale column. A water outlet hole is opened at the lower end of the compaction scale column, and a filter screen is connected inside the lower end of the water outlet hole. The filter screen is used to isolate adsorbent particles, and a measuring scale is engraved on the outer periphery of the compaction scale column.
[0008] A base, wherein a measuring cylinder is connected to the middle of the upper end of the base.
[0009] Preferably, the fit gap between the measuring cylinder and the compaction scale column is 0.02 to 0.04 mm, and the compaction scale column is in contact with the inner wall of the measuring cylinder.
[0010] Preferably, the inner diameter of the measuring cylinder is Φ35.7±0.02mm, and the length of the measuring cylinder is 400mm.
[0011] Preferably, the diameter of the compaction scale column is Φ35.7±0.02mm, and the length of the compaction scale column is greater than the height of the measuring cylinder, and the compaction scale column is completely inserted into the measuring cylinder.
[0012] Preferably, the outer surface of the compaction scale column is engraved with measurement graduations at equal intervals, and each small division of the measurement scale represents 1 ml, and the measurement scale displays the volume of the adsorbent.
[0013] Preferably, the filter screen can filter and isolate admixture particles with a diameter range of 0.1-2 mm.
[0014] The beneficial effects of this utility model are as follows: by tightly fitting and pulling the measuring cylinder and the compaction scale column together, the adsorbent is quickly compacted by the weight of the compaction scale column itself, avoiding adsorbent floating and bridging, thereby improving measurement accuracy; changing the original method that required a long time of settling before measurement, the measurement time is greatly shortened and work efficiency is improved by the gravity compaction of the compaction scale column and the water outlet holes and channels inside the compaction scale column for rapid drainage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-5A blood perfusion device adsorbent filling volume detector includes a measuring cylinder 1 with an internal cavity for loading adsorbent particles mixed with liquid; a compaction scale column 2 connected to the inside of the measuring cylinder 1 with an internal groove and a water outlet hole 201 at the lower end of the compaction scale column 2, the filter screen 3 for isolating adsorbent particles, and a measuring scale 202 engraved on the outer periphery of the compaction scale column 2; and a base 4 with the measuring cylinder 1 connected to the middle of its upper end for stable placement.
[0023] Reference Figure 3 , Figure 4 The fitting clearance between the measuring cylinder 1 and the compaction scale column 2 is 0.02–0.04 mm. The compaction scale column 2 fits snugly against the inner wall of the measuring cylinder 1. Because the fitting clearance between the compaction scale column 2 and the measuring cylinder 1 is only 0.02–0.04 mm, it ensures that the compaction scale column 2 can be smoothly inserted and tightly fitted, while also being easy to remove. The inner diameter of the measuring cylinder 1 is Φ35.7±0.02 mm, and the length of the measuring cylinder 1 is 400 mm. The diameter of the compaction scale column 2 is Φ35.7±0.02 mm, and the length of the compaction scale column 2 is greater than the height of the measuring cylinder 1. The compaction scale column 2 is fully inserted into the measuring cylinder 1 and has a certain weight. The instrument, relying on its own gravity, can quickly compress the adsorbent particles mixed in the liquid and discharge the liquid through the bottom filter screen 3 and the water outlet 201, thereby achieving rapid sedimentation of the adsorbent and accurate measurement of its volume. The outer surface of the compaction scale column 2 is engraved with measurement scales 202 at equal intervals, and each small division of the measurement scale 202 represents 1 ml. The measurement scale 202 displays the volume of the adsorbent. The filter screen 3 can filter and isolate adsorbent particles with a diameter range of 0.1-2 mm. Through the measurement scale 202 and the filter screen 3, the instrument is suitable for detecting blood perfusion devices with adsorbent particles in the range of 0.1-2 mm in size, and the filling volume detection deviation can be controlled to ±0.1 ml.
[0024] Working principle: First, the adsorbent particles from the blood perfusion device to be tested are mixed evenly with water and then poured into the measuring cylinder 1. Next, the compaction scale column 2 is slowly inserted into the measuring cylinder 1, ensuring a tight fit between the compaction scale column 2 and the inner wall of the measuring cylinder 1. Since the clearance between the compaction scale column 2 and the measuring cylinder 1 is only 0.02-0.04mm, this ensures that the compaction scale column 2 can be smoothly inserted and tightly fitted, while also allowing for easy removal. After insertion, the compaction scale column 2, due to its weight, will quickly compact under its own gravity. When the adsorbent particles are compacted, water will be discharged from the water outlet 201 and the channel in the middle of the compaction scale column 2. At the same time, the filter screen 3 at the bottom of the compaction scale column 2 can isolate the adsorbent particles and prevent them from entering the water outlet 201 and being discharged with the water flow. When the compaction scale column 2 is pressed down to the bottom, the adsorbent particles have been quickly compacted and the water has been discharged. At this time, the filling volume of the adsorbent can be obtained by reading the measurement scale 202 on the compaction scale column 2. Since the scale column has a scalar volume of 1 ml per small division, high-precision measurement can be achieved.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
