Technical Field

[0001] This utility model relates to the field of medical material testing technology, and more specifically, to a medical material sample processing device. Background Technology

[0002] Medical material testing refers to a series of tests and evaluations conducted on substances used in medical devices and sanitary materials to verify whether they meet relevant quality standards and safety requirements. The testing scope includes multiple aspects such as physical properties, chemical composition, biocompatibility, and microbiological indicators, ensuring the safety and effectiveness of these materials in clinical use.

[0003] In the research and application of medical materials, cytotoxicity testing is a crucial step in ensuring their safety and efficacy. Currently, the process of sample processing and cell culture testing for medical materials is quite cumbersome, typically requiring the sample to be processed before being transferred to a cell culture environment for observation and testing. However, this sample processing procedure is inefficient, involving multiple steps and easily introducing contamination, thus affecting the accuracy of the test results. Therefore, there is an urgent need to design a medical material sample processing device that integrates cell culture and sample processing and is easy to operate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a medical material sample processing device that solves the problems of cumbersome sample processing procedures requiring multiple steps, which are not only inefficient but also prone to introducing contamination and affecting the accuracy of test results.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A medical material sample processing device includes an upper sample tube, an outer tube, and a bottom tube. The outer tube is fixedly mounted on the upper side of the bottom tube. A detachable lower sample tube is inserted inside the outer tube. The upper sample tube is fixedly mounted on the upper side of the lower sample tube. A sealing film is sealed at the bottom of the lower sample tube. A detachable sealing cap is fitted at the upper end of the upper sample tube. Multiple sets of vertically structured puncture needles are provided at the bottom of the inner side of the bottom tube. A support spring is provided inside the outer tube. The bottom of the support spring is fixedly connected to the bottom of the outer tube. A support retaining ring is fixedly mounted at the upper end of the support spring. The lower sample tube is inserted into the support retaining ring and the support spring.

[0007] Furthermore, the upper sample tube and the lower sample tube are an integral structure, the diameter of the upper sample tube is larger than the diameter of the lower sample tube, the outer tube and the bottom tube are an integral structure, the diameter of the outer tube is larger than the diameter of the bottom tube, the specifications of the upper sample tube are compatible with the specifications of the outer tube, and the diameter of the lower sample tube is smaller than the diameter of the bottom tube.

[0008] Furthermore, two sets of limiting blocks are symmetrically arranged on the annular surface of the upper sample cylinder near the bottom position, and two sets of guide grooves adapted to the limiting blocks are symmetrically arranged on the inner wall of the outer cylinder. The guide groove is composed of a vertical slide groove, a horizontal slide groove and a guide slide groove. The guide slide groove and the vertical slide groove are both opened on the inner wall of the outer cylinder and are connected to each other through the horizontal slide groove. The included angle between the two is 90 degrees. The upper end of the guide slide groove is connected to the upper end of the outer cylinder, and its lower end is connected to one end of the horizontal slide groove. The upper end of the vertical slide groove is connected to the other end of the horizontal slide groove. The length of the vertical slide groove is the same as the length of the lower sample cylinder.

[0009] Furthermore, scale lines are engraved on both the lower sample cylinder and the bottom cylinder ring surface.

[0010] Furthermore, the upper sample cylinder, outer cylinder, lower sample cylinder, and bottom cylinder are all made of medical-grade transparent plastic.

[0011] Furthermore, the bottom of the bottom cylinder is provided with a bottom plate, the diameter of which is larger than that of the outer cylinder, and a layer of anti-slip rubber pad is attached to the bottom of the bottom plate.

[0012] Furthermore, the upper sample cylinder has an external thread on its annular surface near the upper end, and the sealing cap has an internal thread on its inner annular surface. The sealing cap is screwed into the upper sample cylinder for sealing connection via the threads.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, by setting an integrated upper sample tube and lower sample tube, as well as an outer tube and a bottom tube, can simultaneously perform sample processing and cell culture. After sample processing, the sample can be easily mixed with the cell solution without transfer, reducing operation steps, improving operation efficiency and convenience, and reducing the risk of contamination.

[0015] 2. This utility model utilizes a guide groove to allow the lower sample cylinder to move along a predetermined trajectory during insertion into the outer cylinder, ultimately achieving accurate positioning. The guide groove provides initial positioning of the limiting block, facilitating a rapid initial connection between the upper sample cylinder and the outer cylinder. Simultaneously, the transverse groove limits the movement of the limiting block, preventing the upper sample cylinder from moving downwards and thus avoiding accidental downward movement that could cause the puncture needle to puncture the sealing film at the bottom of the lower sample cylinder. Furthermore, the vertical groove guides the movement of the lower sample cylinder within the outer cylinder, improving smoothness and preventing deviation or jamming during movement.

[0016] 3. The sample cylinder and the bottom cylinder of this utility model are engraved with scale lines. The scale lines provide an intuitive reference for the added solutions and reagents, avoiding the trouble of using additional measuring tools and improving the efficiency and accuracy of operation.

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1 to 7As shown, a medical material sample processing device includes an upper sample cylinder 2, an outer cylinder 3, and a bottom cylinder 4. The outer cylinder 3 is fixedly mounted on the upper side of the bottom cylinder 4, and the outer cylinder 3 and the bottom cylinder 4 are an integral structure used to store cell culture medium. A detachable lower sample cylinder 7 is inserted inside the outer cylinder 3, and the upper sample cylinder 2 is fixedly mounted on the upper side of the lower sample cylinder 7. A sealing film 10 is sealed at the bottom of the lower sample cylinder 7. The upper sample cylinder 2 and the lower sample cylinder 7 are an integral structure used to store medical material samples to be processed. A detachable sealing cap 1 is fitted to the upper end of the upper sample cylinder 2 to ensure the airtightness of the sample storage and prevent external contamination. Multiple sets of vertically structured puncture needles 8 are provided on the inner bottom of the bottom cylinder 4 to puncture the sealing film 10 at the bottom of the lower sample cylinder 7, allowing the sample solution in the lower sample cylinder 7 to flow into the bottom cylinder 4. When the lower sample cylinder 7 is inserted into the outer cylinder 3 and moves downward to a certain position, the puncture needles 8 will puncture the sealing film 10 at the bottom of the lower sample cylinder 7, allowing the sample to flow out smoothly for subsequent processing, avoiding the cumbersome steps and potential contamination in traditional operations. A support spring 12 is provided inside the outer cylinder 3, with its bottom fixedly connected to the bottom of the outer cylinder 3. A support retaining ring 11 is fixedly attached to the upper end of the support spring 12. The lower sample cylinder 7 is inserted into the support retaining ring 11 and the support spring 12. The support retaining ring 11 and the support spring 12 support the lower sample cylinder 7 and allow it to move up and down within the outer cylinder 3 and the bottom cylinder 4. This design solves the problem that the existing medical material sample processing process is cumbersome, requiring multiple steps, which is not only inefficient but also prone to contamination, affecting the accuracy of the test results.

[0028] In this embodiment, the upper sample cylinder 2 and the lower sample cylinder 7 are an integral structure, with the diameter of the upper sample cylinder 2 being larger than that of the lower sample cylinder 7. This integral structure avoids sample leakage caused by loose connections between the upper and lower sample cylinders 7, ensuring the sealing and integrity of the sample during transfer and processing. The outer cylinder 3 and the bottom cylinder 4 are also an integral structure, with the diameter of the outer cylinder 3 being larger than that of the bottom cylinder 4. This integral design makes the connection between the outer cylinder 3 and the bottom cylinder 4 more secure, enhancing the structural stability of the entire device. The specifications of the upper sample cylinder 2 are compatible with those of the outer cylinder 3, while the diameter of the lower sample cylinder 7 is smaller than that of the bottom cylinder 4, allowing the upper sample cylinder 2 and the lower sample cylinder 7 to fit and connect with the outer cylinder 3 and the bottom cylinder 4, facilitating assembly.

[0029] In this embodiment, two sets of limiting blocks 9 are symmetrically arranged on the annular surface of the upper sample cylinder 2 near the bottom. Two sets of guide grooves adapted to the limiting blocks 9 are symmetrically arranged on the inner wall of the outer cylinder 3. Each guide groove consists of a vertical slide groove 13, a horizontal slide groove 14, and a guide slide groove 15. Both the guide slide groove 15 and the vertical slide groove 13 are located on the inner wall of the outer cylinder 3 and are connected by the horizontal slide groove 14, with an included angle of 90 degrees. The upper end of the guide slide groove 15 is connected to the upper end of the outer cylinder 3, and its lower end is connected to one end of the horizontal slide groove 14. The upper end of the vertical slide groove 13 is connected to the other end of the horizontal slide groove 14. The length of the vertical slide groove 13 is the same as the length of the lower sample cylinder 7. The limiting blocks 9, as connecting and positioning components between the upper sample cylinder 2 and the outer cylinder 3, cooperate with the guide grooves on the inner wall of the outer cylinder 3 to achieve precise movement and positioning of the lower sample cylinder 7 within the outer cylinder 3. The guide groove allows the lower sample cylinder 7 to move along a predetermined trajectory during insertion into the outer cylinder 3, ultimately achieving accurate position fixation.

[0030] The guide groove 15 is used to initially position the limiting block 9, thereby achieving a preliminary and rapid connection between the upper sample cylinder 2 and the outer cylinder 3. At the same time, the transverse groove 14 limits the limiting block 9, preventing the upper sample cylinder 2 from moving downward and preventing accidental downward movement of the upper sample cylinder 2, which could cause the puncture needle 8 to puncture the sealing film 10 at the bottom of the lower sample cylinder 7. In addition, the vertical groove 13 guides the movement of the lower sample cylinder 7 within the outer cylinder 3, improving the smoothness of movement and preventing deviation and jamming during movement.

[0031] In this embodiment, scale lines 5 are engraved on the annular surfaces of both the lower sample cylinder 7 and the bottom cylinder 4. The scale lines 5 provide an intuitive reference for the added solutions and reagents, avoiding the trouble of using additional measuring tools and improving the efficiency and accuracy of the operation.

[0032] In this embodiment, the upper sample cylinder 2, outer cylinder 3, lower sample cylinder 7, and bottom cylinder 4 are all made of medical transparent plastic, allowing operators to directly observe the state of the sample inside the device and the operation process.

[0033] In this embodiment, the bottom of the bottom cylinder 4 is provided with a bottom plate 6. The diameter of the bottom plate 6 is larger than that of the outer cylinder 3, which increases the contact area between the device and the placement surface such as a table or laboratory table, thereby improving the placement stability of the device. In addition, a layer of anti-slip rubber pad 61 is pasted on the bottom of the bottom plate 6, which can improve the anti-slip properties of the bottom plate 6 and increase the friction between the bottom plate 6 and the placement surface, preventing the device from tipping over due to sliding during operation.

[0034] In this embodiment, the upper sample cylinder 2 has an external thread 21 on the annular surface near the upper end, and the sealing cap 1 has an internal thread on the inner annular surface. The sealing cap 1 is screwed into the upper sample cylinder 2 for sealing connection through the thread. The design of the external thread 21 and the internal thread interlocking with each other provides a stable connection between the upper sample cylinder 2 and the sealing cap 1, while ensuring the sealing performance of the connection.

[0035] The working principle of this medical material sample processing device:

[0036] In actual use, the culture medium containing cells is added to the bottom cylinder 4, allowing the cells to be cultured in the bottom cylinder 4. Then, the sealing cap 1 is opened, the sample is placed into the lower sample cylinder 7, and an appropriate amount of extraction solution is added to the lower sample cylinder 7. The sealing cap 1 is then closed. Next, the integrated upper sample cylinder 2 and lower sample cylinder 7 are lifted as a whole and aligned with the upper end of the outer cylinder 3, so that the limiting block 9 on the annular surface of the upper sample cylinder 2 enters the guide groove 15 in the guide groove on the inner wall of the outer cylinder 3. Since the upper end of the guide groove 15 is connected to the upper end of the outer cylinder 3, the limiting block 9 can slide in smoothly, achieving a preliminary and rapid connection between the upper sample cylinder 2 and the outer cylinder 3. At this time, the lower sample cylinder 7 is inserted into the outer cylinder 3, and the support retaining ring 11 and the support spring 12 begin to provide support for the lower sample cylinder 7.

[0037] After sample processing is complete, rotate the upper sample cylinder 2 counterclockwise, causing the limiting block 9 to slide along the horizontal groove 14 into the vertical groove 13. Then, press the upper sample cylinder 2 downwards, causing the limiting block 9 to move downwards along the vertical groove 13, simultaneously compressing the support spring 12. Guided by the vertical groove 13, the lower sample cylinder 7 continues to move downwards until its bottom contacts the puncture needle 8 at the bottom of the inner side of the bottom cylinder 4. The puncture needle 8 punctures the sealing film 10 at the bottom of the lower sample cylinder 7, allowing the sample extraction solution in the lower sample cylinder 7 to flow into the bottom cylinder 4 and mix with the cell culture medium stored in the bottom cylinder 4. During the process of the sample solution flowing into the bottom cylinder 4 and mixing with the cell culture medium, the operator can directly observe the mixing through the transparent outer cylinder 3, upper sample cylinder 2, lower sample cylinder 7, and bottom cylinder 4, such as changes in solution color and flow rate, to determine whether the mixing is uniform. After a suitable mixing time, remove the upper sample cylinder 2 and lower sample cylinder 7, and extract the mixed solution from the bottom cylinder 4 for testing and analysis.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
