Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to a plasma sample collection device for plasma detection. BACKGROUND

[0002] Plasma is an important component of blood, which is a light yellow transparent liquid after removing blood cells and fibrinogen, accounting for about 55% of the total volume of blood. Plasma contains a large amount of protein, electrolyte, nutrient, hormone and metabolic waste, etc., which plays a crucial role in maintaining normal physiological functions of the human body. Plasma collection refers to extracting a certain amount of plasma from the human body through specific technical means for subsequent blood product preparation, clinical detection and scientific research, etc. This process needs to strictly follow the operation procedures to ensure that the quality of the collected plasma meets the relevant standards.

[0003] In the existing plasma extraction process, the whole blood sample is usually obtained by venous blood sampling, and then the whole blood is centrifuged on a high-speed centrifuge to separate the plasma. The centrifuged plasma is extracted by a specific extraction device, such as a needle tube or a straw, and is transferred to a test tube or other container for subsequent detection or analysis. This step is crucial for the accuracy and reliability of the plasma sample, which directly affects the accuracy of the subsequent detection results.

[0004] However, the existing plasma extraction process has some obvious shortcomings, especially in quantitative extraction. The traditional extraction method mostly relies on manual operation, such as using a needle tube for extraction, which is not only cumbersome to operate, but also difficult to accurately control the amount of extracted plasma. In actual operation, the operator needs to judge the amount of extracted plasma according to experience, which not only affects the accuracy of extraction, but also increases the risk of operation errors. In addition, the traditional extraction method also has the risk of plasma leakage, which may cause plasma contamination or waste if not handled properly, causing unnecessary trouble to the subsequent detection work.

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 scope of protection of the present utility model. The directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present utility model are based solely on the accompanying drawings of the present utility model and are not intended to specifically limit the present utility model.

[0022] Example: A plasma sample collection device for plasma testing, such as... Figures 1-5 As shown, the device includes a handle 1, a conical tube 2, an inlet tube 3, a rubber disc 4, a rack 5, a mounting base 6, a motor 7, a gear 8, a battery 9, a charging port 10, and a first controller 1001. The lower end of the handle 1 is connected to the conical tube 2, and the lower end of the conical tube 2 is connected to the inlet tube 3. The rubber disc 4 is slidably connected inside the handle 1, and the rack 5 is connected to the rubber disc 4. The mounting base 6 is connected inside the handle 1, and the motor 7 is mounted on the mounting base 6. The output shaft of the motor 7 is connected to the gear 8, and the gear 8 meshes with the rack 5. The battery 9, which powers the motor 7, is installed inside the handle 1, and the charging port 10 is located at the top of the handle 1. The charging port 10 is wired to the battery 9. The first controller 1001 is mounted on the handle 1 and wired to the motor 7. The first controller 1001 has two large buttons, namely "extract" and "release".

[0023] like Figure 2 and Figure 5As shown, it also includes a base 11, an ultraviolet germicidal lamp 12, and a second controller 13. The handle 1 is snapped into the base 11. The tapered tube 2 is inserted into the cylindrical groove of the base 11. The ultraviolet germicidal lamp 12 is installed in the cylindrical groove of the base 11. The second controller 13 is installed outside the base 11 and is wired to the ultraviolet germicidal lamp 12.

[0024] like Figure 2 and Figure 5 As shown, it also includes a fastening rubber ring 14. The fastening rubber ring 14 is fitted on the top of the cylindrical groove of the base 11, and the fastening rubber ring 14 is pressed and engaged with the handle 1.

[0025] like Figure 2 and Figure 3 As shown, it also includes an observation window 15. The tapered tube 2 is provided with an observation window 15 made of transparent material. The tapered tube 2 is made of opaque material, which is highlighted through the transparent observation window 15. Scale is provided on the tapered tube 2.

[0026] like Figure 2 As shown, it also includes a dustproof pad 16, which is provided at the charging port 10 of the handle 1.

[0027] like Figure 3 and Figure 4 As shown, it also includes an anti-slip pad 17, which is fitted onto the handle 1.

[0028] In the initial state, the device is in standby mode, the motor 7 is not started, and the rubber disc 4 is in the initial position inside the handle 1. When medical staff are ready to collect plasma samples, they first hold the entire device through the handle 1 to ensure that the anti-slip sleeve provides a stable grip and prevents it from slipping during operation. Then, the lower end of the conical tube 2, the liquid inlet tube 3, is accurately inserted into the plasma sample to be collected.

[0029] In order to perform quantitative collection, medical staff start the motor 7 through the first controller 1001. After receiving the start signal, the output shaft of the motor 7 starts to rotate, driving the gear 8 connected to it to rotate. In turn, the gear 8 drives the rack 5 meshing with it to move linearly. The rack 5 is connected to the rubber disc 4, so the rubber disc 4 also slides in the handle 1. Medical staff can precisely control the rotation angle of the motor 7 through different buttons on the first controller 1001, thereby determining the distance the rubber disc 4 moves, and thus accurately extracting the required amount of plasma sample.

[0030] When the plasma sample is extracted into the conical tube 2, the medical staff can reverse the motor 7 through the release button on the first controller 1001, drive the rubber disc 4 to move reversely, so as to release the plasma sample in the conical tube 2 into the designated detection container. If non-quantitative collection is required, the medical staff can press the "extraction" button on the first controller 1001, and continuously press the rubber disc 4 to extract the plasma; after releasing, press the "release" button again, and the rubber disc 4 moves reversely to release the plasma.

[0031] After the collection is completed, in order to maintain the cleanliness and sterile state of the device, the medical staff inserts the conical tube 2 into the cylindrical groove of the placement base 11, at this time, the fastening rubber ring 14 is extruded and matched with the handle 1, ensuring that the conical tube 2 is stably fixed in the cylindrical groove, avoiding shaking or falling off, at the same time, the second controller 13 starts the ultraviolet sterilization lamp 12 to sterilize the conical tube 2 and the liquid inlet pipe 3, effectively killing the residual bacteria and viruses, providing safety guarantee for next use.

[0032] During the maintenance of the device, when the battery 9 is insufficient, the medical staff can charge the battery 9 through the charging port 10 at the top of the handle 1, and when not charging, the dust pad 16 blocks the charging port 10, preventing dust and moisture from entering the inside of the handle 1, protecting the safety of the circuit and the battery 9.

[0033] In addition, the transparent observation window 15 provided on the conical tube 2 allows the medical staff to directly observe the state and amount of the plasma sample without opening the conical tube, which is convenient for preliminary judgment and recording.

[0034] The above has carried on the detailed introduction to the present application, the principle and implementation mode of the present application are described in this paper by applying specific examples; the above example is only used to help understand the method and core idea of the present application; at the same time, for the general technical personnel in the art, according to the idea of the present application, the specific implementation mode and application range will be changed; according to the above, the content of the specification should not be understood as the limitation of the present application.
