Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically to a sample delivery container. Background Technology
[0002] Prostatic fluid, a milky-white, thin liquid secreted by the prostate gland, is an important component of semen. Prostatic fluid testing is a laboratory diagnostic method for various diseases and is one of the routine clinical examinations. Routine prostatic fluid testing generally includes visual examination and microscopic examination. Prostatic fluid is collected by an outpatient physician massaging the prostate gland through the anus. During the massage, prostatic fluid drips from the urethra and is collected on a glass slide and sent to the testing window for analysis. However, the aforementioned collection and delivery process has the following drawbacks:
[0003] 1. When prostatic fluid is sent for testing while adhering to a glass slide, it is exposed to the air in an open manner. This method of sending samples may cause hospital-acquired infections and does not meet the requirements of biosafety management.
[0004] 2. Under normal circumstances, very little prostatic fluid is collected, only a few drops. Because the prostatic fluid is exposed to air during transport, there is a risk of evaporation and drying, which will affect the test results. Moreover, after arriving at the testing window, it needs to be immediately sent to a microscope for observation and testing, which can easily disrupt the process and cause inconvenience in actual work.
[0005] 3. The glass slide is fragile and poses a risk of injury to the person holding it from a sharp object, creating a biosafety hazard;
[0006] 4. When glass slides are used as carriers to collect prostatic fluid, they may not have been sterilized, which cannot guarantee that the sample is clean and free of any interfering substances, thus affecting the accuracy of the test results and leading to errors in clinical diagnosis and treatment.
[0007] 5. When prostatic fluid not only needs routine microscopic examination but also involves prostatic fluid tumor cytology and requires cell culture, it is necessary to collect prostatic fluid separately into a specific container for culture, which is costly and cumbersome. Utility Model Content
[0008] The purpose of this invention is to provide a sample delivery container that complies with biosafety management regulations and prevents sample evaporation.
[0009] To achieve the above objectives, the present invention provides a sample container comprising: a base plate, a sample pool recessed in the center of the base plate, and slide rails on both sides of the base plate; a cover glass slide is provided on the upper surface of the base plate located on one side of the sample pool, the cover glass slide can slide along the slide rails to cover the sample pool; a positioning structure is also provided on the base plate, the positioning structure is used to position the cover glass slide when it slides to the closing position, so that the sample pool and the cover glass slide enclose a closed space.
[0010] Furthermore, the cover glass is made of highly transparent plastic.
[0011] Furthermore, the positioning structure includes a damping track, which is recessed on the inner wall of the sample cell on the side away from the starting position of the coverslip. The inner wall of the damping track is provided with a soft elastomer. The length of the coverslip is greater than the length of the sample cell. When the coverslip is placed over the sample cell, the front end of the coverslip is inserted into and fixed in the damping track.
[0012] Furthermore, the positioning structure includes a slot and an insert. The slot is recessed on the inner wall of the sample pool on the side away from the starting position of the coverslip. The front end of the coverslip is provided with an insert corresponding to the position of the slot. When the coverslip is closed on top of the sample pool, the insert is inserted and fixed in the slot.
[0013] Furthermore, the upper surface of the coverslip has an upwardly protruding ridge on the edge away from the sample cell.
[0014] Furthermore, it also includes a sample label, with the sample label and cover glass slide respectively placed on the upper surface of the base plate on both sides of the sample pool.
[0015] Furthermore, the base plate is made of optical plastic.
[0016] Furthermore, the inner wall of the damping track is provided with a wave-shaped soft elastomer.
[0017] Furthermore, the elastomer is made of rubber or silicone.
[0018] With the above method, during examination, samples are directly collected into the sample pool on the base plate or placed in the sample pool after collection, and then the coverslip is pushed to slide along the rail to close the sample pool, placing the sample in a closed space. During testing, the entire sample container is placed directly under the microscope, and the sample in the sample pool can be observed through the coverslip. This avoids sample evaporation when the quantity of liquid samples is small and also avoids the risk of nosocomial infection due to sample exposure to air, meeting biosafety management requirements. After being sent to the testing window, it is not necessary to rush to the microscope for testing; the testing can be carried out sequentially.
[0019] In addition, the base plate is equipped with a positioning structure for the coverslip, which can prevent the coverslip from sliding on its own during transportation, thus preventing the sample pool from opening and exposing the sample to the air, thereby further improving safety.
[0020] Furthermore, the sample pool of this invention can form a closed space when covered by a coverslip. The coverslip can be opened and closed manually. Therefore, when it is necessary to culture the sample for further testing of other items, this invention can facilitate the operator to add culture medium and take samples, making it more versatile in function and simplifying the workflow.

[0027] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0028] See Figures 1 to 3 This is the sample delivery container of this utility model, which can be used to hold samples collected from hospital outpatient clinics for testing.
[0029] The sample delivery container includes a base plate 1, a sample pool 11 recessed in the center of the base plate 1, and slide rails 12 on both sides of the base plate 1. A cover glass 2 is provided on the upper surface of the base plate 1 located on one side of the sample pool 11. The cover glass 2 can slide along the slide rail 12 to cover the sample pool 11, so as to prevent the sample in the sample pool 11 from being exposed to the air and causing volatilization or nosocomial infection. It is especially suitable for containing small amounts of liquid samples such as prostatic fluid.
[0030] The base plate 1 is also equipped with a positioning structure, which is used to position the coverslip 2 when it slides to the closed position, so that the sample pool 11 and the coverslip 2 enclose a closed space. Figure 1 As shown, the positioning structure can be a damping track 111. The damping track 111 is recessed on the inner wall of the sample pool 11 on the side away from the starting position of the coverslip 2. The inner wall of the damping track 111 is provided with a soft elastomer, such as a ring of silicone or rubber. The length of the coverslip 2 is greater than the length of the sample pool 11. When the coverslip 2 is placed on top of the sample pool 11, the front end of the coverslip 2 is inserted into and fixed in the damping track 111. At this time, the soft elastomer such as silicone or rubber will undergo elastic deformation and tightly engage with the front end of the coverslip 2, so that the coverslip 2 will not easily slip off after being placed on, further preventing the sample in the sample pool 11 from being exposed to the air and meeting the requirements of biosafety management.
[0031] Preferably, the elastic body on the inner wall of the damping track 111 has an uneven, wavy surface. The elastic body is distributed circumferentially within the damping track 111 or on two corresponding surfaces within the damping track 111. This way, when the cover glass 2 is inserted into the damping track 111, a certain gap is maintained between it and the uneven elastic body, allowing the cover glass 2 to be inserted into the damping track 111 more smoothly, without making it difficult to enter the damping track 111 due to excessive friction.
[0032] In other embodiments, the positioning structure may also include a slot and a insert. The slot is recessed on the inner wall of the sample pool 11 on the side away from the starting position of the coverslip 2. The insert is protruding from the front end of the coverslip 2 at the position corresponding to the slot. When the coverslip 2 is closed on top of the sample pool 11, the insert is inserted and fixed in the slot, which also prevents the coverslip 2 from easily sliding off after it is closed. Of course, an elastic protrusion can be formed between the coverslip 2 and the slide rail 12 to cooperate with the positioning hole. The slide rail 12 can also be made to be tapered and inclined or to form frictional resistance, etc., as long as the coverslip 2 can slide and close without easily sliding off in the opposite direction.
[0033] The coverslip 2 is made of highly transparent plastic, while the base plate 1 can be made of optical plastic. This allows the sample container to be placed directly under the microscope for observation without opening the coverslip 2 or touching the sample. Compared to currently used glass slides, plastic is more shatter-resistant and portable, avoiding the fragility of glass and preventing injuries to the user or sample spillage that could pose biosafety risks. Furthermore, plastic is inexpensive, can be used only once, and ensures the accuracy of test results.
[0034] This invention also provides an upwardly protruding ridge 21 on the edge of the cover glass 2 away from the sample pool 11. When the sample is collected and the cover glass 2 needs to be covered, the finger can press or push on the ridge 21 to apply force, which can avoid leaving fingerprints on the cover glass 2 and causing inconvenience to subsequent inspections.
[0035] The base plate 1 of this utility model also includes a sample label 13. The sample label 13 and the cover glass 2 are respectively disposed on the upper surface of the base plate 1 on both sides of the sample pool 11. The sample label 13 may have a sample number written on it or a QR code affixed to it, so as to distinguish different samples.
[0036] In addition to microscopic examination, the above-mentioned sample delivery container can also be used for cell culture: the coverslip 2 can be opened and closed manually, so when it is necessary to culture the sample for further testing of other items, this utility model can facilitate the operator to add culture medium, take samples, and observe, making it more versatile in function and simplifying the workflow.
[0037] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
