Description

Technical Field

[0001] The utility model specifically relates to the technical field of basic medical research, and specifically relates to an anti - aspiration pipette filter. Background Technique

[0002] A pipette is a type of liquid transfer device, commonly used for the transfer of small or trace amounts of liquid in a laboratory. Different specifications of pipettes are equipped with different - sized pipette tips. The shapes produced by different manufacturers are slightly different, but the working principles and operation methods are basically the same. When scientific researchers use a pipette to aspirate liquid, sometimes due to too fast speed, the liquid may be accidentally aspirated into the pipette, resulting in contamination or damage to the pipette. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti - aspiration pipette filter to solve the problems raised in the above - mentioned background technique.

[0004] To achieve the above - mentioned purpose, the utility model provides the following technical solution: an anti - aspiration pipette filter, including a pipette body. A pipette tip is arranged on the lower side of the pipette body, and a connection component is arranged on the lower side of the pipette tip. A connection cylinder is arranged under the pipette tip and is connected to the connection component. A filter element is installed on the inner upper side of the connection cylinder, and a suction head is installed on the lower side of the connection cylinder.

[0005] Preferably, an adjustment component is arranged on the inner front side of the pipette body, a finger grip is installed on the outer upper side of the pipette body, and a button is installed on the inner upper side of the pipette body.

[0006] Preferably, the inner diameter of the connection cylinder is the same as the outer diameter of the connection component, and the outer diameter of the connection cylinder is the same as the outer diameter of the bottom end of the pipette tip.

[0007] Preferably, the filter element is made of water - absorbing sponge material.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: for this anti - aspiration pipette filter,

[0009] (1) It is provided with a connection cylinder and a filter element. When aspirating waste liquid, through the action of the filter element, after the waste liquid enters the connection cylinder, through the blocking and adsorption effects of the filter element, the waste liquid is prevented from being directly aspirated into the pipette body, thus playing a good role in protecting the pipette.

[0010] (2) It is provided with a pipette tip, a connection component, a connection cylinder, a filter element and a suction head, making the connection cylinder and the filter element easy to remove and replace, thereby reducing the use and cost of the pipette. Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution: an anti - aspiration pipette filter, a tip 5 is arranged on the lower side of the pipette gun body 1, and a connecting component 6 is arranged on the lower side of the tip 5. A connecting cylinder 7 is arranged below the tip 5, and the connecting cylinder 7 is connected to the connecting component 6. A filter element 8 is installed on the inner side of the upper part of the connecting cylinder 7, and a tip 9 is installed on the lower side of the connecting cylinder 7. After the waste liquid enters the interior of the connecting cylinder 7, due to the function of the filter element 8, the waste liquid is prevented from being directly sucked into the interior of the pipette gun body 1, resulting in the contamination and inoperability of the pipette gun body 1.

[0018] As Figure 1 and Figure 2 shown, an adjusting component 2 is arranged on the front inner side of the pipette gun body 1, a finger grip 3 is installed on the outer side of the upper part of the pipette gun body 1, and a button 4 is installed on the inner side of the upper part of the pipette gun body 1, making the use of the pipette gun body 1 more convenient.

[0019] As Figure 1 and Figure 2 shown, the inner diameter of the connecting cylinder 7 is the same as the outer diameter of the connecting component 6, and the outer diameter of the connecting cylinder 7 is the same as the bottom outer diameter of the tip 5, making the installation of the connecting cylinder 7 more convenient.

[0020] As Figure 3As shown, the filter element 8 is made of water-absorbing sponge material, enabling the filter element 8 to absorb the waste liquid and preventing the waste liquid from being sucked into the pipette body 1.

[0021] Working principle: When using this anti-misaspiration pipette filter, install the connecting cylinder 7 on the connecting component 6 on the lower side of the pipette tip 5, and install the suction tip 9 on the lower side of the connecting cylinder 7. After installation, it can be used. When sucking the waste liquid through the suction tip 9, when the waste liquid is sucked into the connecting cylinder 7, due to the water-absorbing property of the filter element 8, it can prevent the liquid from passing through the filter element 8 and entering the pipette body 1, resulting in the contamination and inoperability of the pipette body 1. After use, just remove the connecting cylinder 7 and replace it. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
