Description

Technical Field

[0001] The utility model relates to the technical field of medical sample collection, in particular to a filtering adsorber. Background Art

[0002] Urine examination is one of the most common detection methods in clinical medicine. There are many methods for obtaining the exfoliated cells contained in urine, such as sedimentation method, centrifugation method, filtration method, etc. The defect of these methods is that they can only be applied to body fluid specimens with small sample volume and high cell content in the sample, but for body fluids such as urine with large volume but small cell content, if centrifugation is used, due to the large volume of body fluids such as urine, multiple centrifugation is required. In the process of centrifugation, multiple centrifuge tubes need to be used, which will lose a large amount of cells in the urine and affect the subsequent test results. If the sedimentation method is used, it takes a certain amount of time, which will cause cell degeneration and affect the accuracy of the test results. The filtration method requires the use of a filter with a large filtration area to avoid the blockage of the filtration channel. Due to the large volume, this will make the cell storage and transportation very inconvenient and the later test process takes up a large space. Therefore, there is currently a lack of an effective and convenient method to carry out rapid and simple processing, obtain the exfoliated cells in the urine, and recycle and preserve them for subsequent medical examinations by the inspection department.

[0003] Currently, filter adsorbers are mostly used to filter and adsorb urine, and then collect cells in the urine for sampling and analysis. However, existing filter adsorbers have problems such as easy clogging and leakage, and the urine adsorbent is difficult to remove. Utility Model Content

[0004] The purpose of the utility model is to provide a filter adsorber to solve at least one of the above technical problems existing in the prior art.

[0005] In order to solve the above technical problems, the utility model provides a filter adsorber, comprising: a liquid bag, a filter adsorption tube and an adsorption body;

[0006] The fluid bag is used to collect and store the detected liquid;

[0007] The upper inlet of the filter adsorption tube is connected to the liquid outlet at the bottom of the fluid bag;

[0008] A plurality of liquid flow channels are arranged in the filter adsorption tube;

[0009] A plurality of the adsorbents are respectively filled in a plurality of the liquid flow channels, and are used to adsorb and capture cells in the detected liquid when the detected liquid flows through the liquid flow channels.

[0010] The present application greatly improves the filtration efficiency by setting up multiple liquid flow channels in the filter adsorption tube, and each liquid flow channel is respectively provided with an adsorbent. After the multiple adsorbents are taken out, the cells on the adsorbents are washed and separated more quickly, thereby improving the separation efficiency.

[0011] Furthermore, the filter adsorber further comprises a connecting frame, the connecting frame is detachably connected to the lower end outlet of the filter adsorption tube, and the connecting frame is provided with a through hole for the detected liquid flowing out of the liquid flow channel to pass through;

[0012] The adsorbent is connected to the connecting frame and is used to pull the adsorbent out of the liquid flow channel through the connecting frame.

[0013] Furthermore, the absorbent body is connected to the connecting frame by means of snap-fitting, bonding or welding.

[0014] Among them, the clamping methods can be specifically divided into anchoring type, bayonet type, clamp type and plug-in type.

[0015] Furthermore, a plurality of central columns are vertically arranged on the connecting frame, and the central columns are inserted into the adsorption body to support the adsorption body and bring the adsorption body out when the connecting frame is removed.

[0016] Furthermore, the central column is provided with a plurality of barbs for grasping the absorbent body.

[0017] Furthermore, a filter is installed inside the liquid bag to perform preliminary filtering on the liquid to be tested and remove impurities in the liquid to be tested.

[0018] Impurities are usually substances with larger particle sizes that affect the accuracy of the test results. After the liquid to be tested is initially filtered, the accuracy of the test is improved and the probability of impurities clogging the adsorbent can be reduced.

[0019] Furthermore, the adsorbent is a filter adsorbent made of microporous adsorbent material.

[0020] More preferably, the absorbent is a filter absorbent made of a flexible microporous absorbent material, wherein the flexible microporous absorbent material can be sponge, bubble cotton, non-woven fabric, cotton and linen, filter paper or a filter made of a protein material.

[0021] Of course, the microporous adsorption material can also be a hard microporous adsorption material.

[0022] Furthermore, the adsorbent is a polymer material that has been subjected to ion exchange and thus has a positive or negative charge.

[0023] For example, sponge, bubble cotton, non-woven fabric, cotton and linen, filter paper or filter elements made of protein materials can be soaked in ion exchangers to form the above-mentioned adsorbents with positive or negative charges. Ion exchangers can be inorganic or organic materials, such as zeolite, sulfonated coal and ion exchange resins.

[0024] Furthermore, the adsorbent is formed by stacking a number of sheet-like bodies.

[0025] The adsorbent is composed of a plurality of the sheet-like bodies, and after being drawn out, it is convenient to quickly flush out the cells on the sheet-like bodies for disease detection.

[0026] Optionally, a plurality of the sheet-like bodies are stacked in sequence along the height direction.

[0027] In the same liquid flow channel, the central column passes through all the sheet-like bodies, thereby facilitating the removal of all the sheet-like bodies.

[0028] Preferably, a plurality of the sheet bodies are arranged in sequence along the horizontal direction, and the sheet bodies are fixedly connected to the connecting frame. That is, each sheet body is arranged vertically along the height, and the bottom of each sheet body is fixedly connected to the connecting frame. All the sheet bodies can be taken out at the same time by using the connecting frame.

[0029] Furthermore, the connecting bracket is connected to the lower end outlet of the filter adsorption tube by means of threads or snap-fitting.

[0030] Furthermore, 3 to 6 liquid flow channels are arranged in the filter adsorption tube.

[0031] The liquid to be detected may be body fluids such as urine, sweat or blood, or other liquids carrying target cells or substances to be detected.

[0032] By adopting the above technical solution, the utility model has the following beneficial effects:

[0033] The utility model provides a filtering adsorber with fast filtering speed and high adsorption efficiency. After a plurality of adsorbents are taken out, the cells on the adsorbents can be washed and separated more quickly, thereby improving the separation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
