Description

Technical Field

[0001] This utility model belongs to the field of clinical and scientific research technology in otolaryngology-head and neck surgery, specifically involving a disposable sterile middle ear effusion collection tube. Background Technology

[0002] Secretory otitis media is a common disease and a key and challenging area of ​​clinical and basic research in otolaryngology.

[0003] 1. Significant waste of effusion: The amount of effusion itself is only 1 ml or less. The existing suction tube is too long, which causes a large amount of the already limited middle ear effusion to remain in the lumen during the aspiration process, significantly reducing the sample recovery rate and affecting the accuracy of subsequent tests.

[0004] 2. Poor compatibility: The front and rear end connection devices of the suction tube are not compatible with the specifications of commonly used negative pressure suction systems and otological suction heads in clinical practice, resulting in problems such as air leakage at the interface or inconvenience in operation; the lack of standardized design makes it difficult to be compatible with current domestic models of otological instruments, increasing the complexity of operation.

[0005] 3. Low sample processing efficiency: Existing devices cannot directly freeze and preserve samples after aspiration, leading to degradation of bioactive components during transport; lack of integrated centrifugation compatible design, requiring multiple transfers of samples to centrifuge tubes, increasing the risk of contamination and operational steps; therefore, we propose a disposable sterile middle ear effusion collection tube. Utility Model Content

[0006] The purpose of this invention is to provide a disposable sterile middle ear effusion collection tube to solve the existing problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disposable sterile middle ear effusion collection tube, comprising a tube body, a functional cap, an ear suction tube interface, a negative pressure suction tube interface, and a sealing cap. The top of the tube body is fitted with the functional cap, which is fixedly connected to the tube body by threads. The top of the functional cap is provided with two connecting tubes, the bottom of which extends to the inner side of the bottom of the functional cap. The top of the two tubes are respectively provided with an ear suction tube interface and a negative pressure suction tube interface.

[0008] Preferably, the length is CM.

[0009] Preferably, the tube body adopts an integrated design of aseptic cryopreservation centrifuge tube.

[0010] Preferably, the top of the tube body is also provided with a sealing cap that can be used in place of the functional cap.

[0011] Preferably, the bottom of the tube body is provided with a raised base around its perimeter, and the raised base and the tube body are an integral structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By adopting a standardized interface design, it is compatible with different specifications of otological suction tips; the connection device is optimized to ensure a tight fit with the negative pressure system, avoiding air leakage or detachment, optimizing connection adaptability, improving operation convenience, and effectively avoiding the incompatibility between the existing device and the commonly used negative pressure suction system and otological suction tips in clinical practice, which would lead to interface leakage and inconvenience in operation.

[0013] 2. The integrated design of the tube body, which is detachable and cryopreservable, reduces assembly steps; it is lightweight and portable, facilitating rapid operation in clinical and research settings. After aspiration, it can be directly sealed and stored at low temperature; it uses leak-proof and evaporation-proof materials to ensure sample integrity, realize the direct cryopreservation function, and protect sample activity. This avoids the situation where traditional devices cannot directly freeze samples and require transfer to cryopreservation tubes, which can easily lead to liquid accumulation, evaporation, or component degradation.

[0014] 3. By designing a centrifugation-compatible structure at the bottom of the tube, the collection tube can be directly placed into the centrifuge, reducing sample transfer; the tube material is optimized to ensure no deformation or leakage during centrifugation, avoiding the situation where existing devices require transferring accumulated liquid to the centrifuge tube, increasing the risk of contamination and operational steps.

[0015] 4. By designing the connecting tube, the length and diameter of the suction tube are optimized, the volume of the ineffective cavity is reduced, the efficiency of fluid collection is improved, fluid waste is reduced, and the sample recovery rate is increased. This solves the problem that traditional suction tubes are too long, causing a large amount of middle ear effusion to remain in the lumen during aspiration, resulting in serious sample loss.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution for a disposable sterile middle ear effusion collection tube: it includes a tube body 1, a functional cover 2, an ear suction tube interface 3, a negative pressure suction tube interface 4, and a sealing cover 5. The top of the tube body 1 is fitted with the functional cover 2, and the functional cover 2 is fixedly connected to the tube body 1 by threads. The top of the functional cover 2 is provided with two connecting tubes 6, the bottom of which extends to the inner side of the bottom of the functional cover 2. The top of the two connecting tubes 6 is provided with the ear suction tube interface 3 and the negative pressure suction tube interface 4, respectively.

[0020] Specifically, the length of connecting pipe 6 is 1 cm.

[0021] Specifically, tube 1 adopts an integrated design of sterile cryopreservation centrifuge tube, and the material meets medical-grade standards, and is resistant to low temperature (-196℃ liquid nitrogen cryopreservation) and high-speed centrifugation (≥10,000 rpm).

[0022] Specifically, the top of the tube body 1 is also provided with a sealing cap 5 that is used in place of the functional cap 2.

[0023] Specifically, the bottom of the tube body 1 is provided with raised bases 7 around the perimeter, and the raised bases 7 and the tube body 1 are an integral structure.

[0024] In this implementation scheme, during use, the otological suction tip is inserted into the otological suction tube interface 3 at the head of the tube body 1, ensuring a tight connection. The negative pressure aspirator is then connected to the negative pressure suction tube interface 4 at the head of the tube body 1, forming a closed suction system. Negative pressure suction is initiated, and the middle ear effusion flows directly into the short connecting tube 6 through different types of otological suction tips, and quickly flows into the sterile cryopreservation centrifuge tube below, reducing tube lumen residue. When freezing is required, after aspiration, the head of the tube body 1 is removed, and the sealing cap 5 is placed on it. It can be directly placed in liquid nitrogen or a -80°C freezer for storage to avoid sample degradation. When centrifugation is required, there is no need to change the tube; the entire cryopreservation centrifuge tube is placed in a centrifuge for high-speed centrifugation separation, reducing the risk of contamination.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
