Description

Technical Field

[0001] This invention relates to the field of gynecological examination technology, and more specifically to a gynecological examination sample processing device. Background Technology

[0002] Gynecological sample processing devices are specially designed for the extraction and preparation of gynecological samples. These samples are typically used for routine diagnosis of gynecological diseases or for related medical research. By processing and analyzing these samples, doctors can accurately diagnose gynecological diseases such as cervicitis and vaginitis. By processing and analyzing large amounts of sample data, researchers can gain a deeper understanding of the pathogenesis and treatment methods of gynecological diseases, which helps to promote the development of gynecological medicine, improve the level of diagnosis and treatment, and plays an important role in clinical diagnosis.

[0003] Traditional gynecological sample processing devices typically include the following components to support sample collection, processing, and storage: a sample collection component, which uses swabs to collect samples from the patient, such as vaginal secretions. The swabs are usually made of soft, absorbent material to ensure sufficient sample volume. The collected samples are stored in airtight containers to prevent contamination during transport or storage. A sample processing component is used to smear the sample onto a glass slide for microscopic observation. A sample storage component uses sample tubes to store the processed sample for subsequent laboratory testing or preservation. These tubes are typically airtight and labeled to ensure sample integrity and traceability. For samples requiring cryopreservation, refrigeration equipment may also be included to provide a stable low-temperature environment, ensuring the sample does not deteriorate or degrade during storage.

[0004] By observing and analyzing existing gynecological examination sample processing devices, it can be found that they basically meet the functions of gynecological clinical sample collection and examination, but the following problems still exist: First, before the collected sample is prepared into a solution, there is a transfer process. During this process, the sample is not protected, and the normal morphology and structure of cells may undergo morphological changes or degradation. In addition, the ambient temperature of the collection component is very different from that of the human body, and the microbial activity and cell structure in the sample may be affected by temperature. For example, vaginal microecological test samples need to be sealed after collection and sent for testing immediately to prevent drying and pay attention to keeping warm. This helps to maintain the original state of the sample and improve the accuracy of the test. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The gynecological examination sample processing device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2 This invention provides a gynecological examination sample processing device, including a housing assembly 1. The housing assembly 1 includes a sampling sleeve 101, a handheld top plate 102 installed at the rear end of the sampling sleeve 101, a stop ring 103 installed inside the sampling sleeve 101, and a piston assembly 2 installed inside the stop ring 103. The piston assembly 2 includes a pull block 201, a moving shaft 202 installed at the front end of the pull block 201, a sealing piston 203 installed at the front end of the moving shaft 202, and a first toothed block 202 formed on the side of the moving shaft 202. 1. A second toothed block 2022 is provided below the moving shaft 202. A disinfection component 7 is installed inside the moving shaft 202. A solvent filling component 5 is installed above the front end of the sampling sleeve 101. The solvent filling component 5 includes a solvent bottle 510. A stabilizing hand support 104 is installed below the sampling sleeve 101. A solution receiving component 6 is installed at the front end of the stabilizing hand support 104. A sampling component 3 is installed at the front end of the sampling sleeve 101. A blocking component 4 is installed on the outside of the sampling sleeve 101. The blocking component 4 includes a protective shell 401.

[0033] In this embodiment, it should be specifically explained that when medical personnel use this invention to sample a patient, they hold the stabilizing hand support 104 and the pull block 201 to stabilize the device. Then, they push the pull block 201 to expel the air inside the sampling sleeve 101 and insert the sampling component 3 into the patient's body. Subsequently, they slowly pull out the pull block 201. The movement of the pull block 201 causes the moving shaft 202 to move backward, which in turn causes the sealing piston 203 to move backward. Using negative pressure, the fluid secreted by the patient is drawn into the sampling component 3. The sealing piston 203 is flush with the inner wall of the sampling sleeve 101. In a sealed state, the collected liquid exists only at the front end of the sealing piston 203. As the moving shaft 202 moves further back, the moving shaft 202 drives the mechanism inside the protective shell 401 to move, so that the connection between the sampling component 3 and the sampling sleeve 101 is closed. At the same time, the first tooth block 2021 drives the solvent filling component 5 to move, so that the solvent bottle 510 is opened, and the solvent inside the solvent bottle 510 is released into the cavity between the sampling component 3 and the sealing piston 203 and mixes with the collected sample. When the solvent in the solvent bottle 510 is used up, the solvent bottle 510 can be replaced.

[0034] As the moving shaft 202 moves further backward, the sealing piston 203 reaches above the solution collection assembly 6. At this time, another first tooth block 2021 moves to the position of the solvent filling assembly 5 and drives the solvent filling assembly 5 to close. At the same time, the second tooth block 2022 drives the internal mechanism of the solution collection assembly 6 to move, so that the mixed liquid at the front end of the sealing piston 203 finally enters the interior of the solution collection assembly 6 for medical staff to test or observe the sample.

[0035] After sampling is completed, medical staff can release disinfectant by pressing the disinfection component 7 to disinfect the internal cavity of the sampling sleeve 101.

[0036] The main difference between this embodiment and the prior art is that this embodiment utilizes the principle of hydraulic balance, which allows the sample to be mixed with the solvent in a timely manner as it enters the device, thereby preparing the sample solution and achieving pressure balance. This allows the sample solution to be released into the solution receiving component 6 for storage, specifically the moving shaft 202, the blocking component 4, and the solvent filling component 5. At the same time, a heating device is used to keep the temperature at the sampling position constant, preventing the sample quality from being affected and preventing patient discomfort, specifically the sampling component 3.

[0037] The above structure is the main structure of this embodiment, which solves the problem that gynecological samples cannot be diluted or protected by solvents in time during collection, and also solves the problem that the low surface temperature of the device leads to a decrease in sample quality and discomfort to patients.

[0038] Reference Figure 3 The sampling assembly 3 includes a support shell 301, a heating ring 302 installed inside the support shell 301, a sample collection tube 304 installed inside the heating ring 302, a ball valve 3041 installed at the tail end of the sample collection tube 304, a sealing block 305 installed at the connection between the heating ring 302 and the sampling sleeve 101, and a sampling head 303 installed at the front end of the support shell 301. The sampling head 303 has an inlet hole 3031 on its surface.

[0039] In this embodiment, it should be specifically noted that when medical personnel use this device, the outer surface of the support shell 301 and the sampling head 303 will come into contact with the patient's body. At this time, the heating ring 302 starts working, so that the temperature of the support shell 301 is constant and close to the human body temperature, thereby reducing the patient's discomfort. At the same time, it keeps the collected sample in a temperature environment similar to that of the human body, preventing the microorganisms in the sample from changing. The ball valve 3041 has a channel inside. In the initial state, the channel is open. When a certain amount of sample is obtained inside the sampling sleeve 101, the moving shaft 202 continues to slowly withdraw from the inside of the sampling sleeve 101. The moving shaft 202 will drive the blocking component 4 to move, causing the ball valve 3041 to rotate, thereby closing the tail end of the collection tube 304, preventing air from continuing to enter the inside of the sampling sleeve 101 from the sampling head 303, which is conducive to maintaining the pressure balance inside the sampling sleeve 101. The heating ring 302 is an existing structure. The specific structure and connection method of the heating ring 302 will not be described in detail in this embodiment.

[0040] Reference Figure 4 The moving shaft 202 has a third tooth block 2023 on its side. The protective shell 401 has a first gear set 403 installed inside. One end of the first gear set 403 is equipped with a blocking gear 402, and the other end of the first gear set 403 is equipped with a second gear set 404. The second gear set 404 includes an opening and closing gear 4041, which is fixedly connected to the ball valve 3041.

[0041] In this embodiment, it should be specifically explained that when the moving shaft 202 is slowly pulled out from the inside of the sampling sleeve 101, the third tooth block 2023 will pass through the blocking gear 402. At this time, the third tooth block 2023 meshes with the blocking gear 402. The movement of the third tooth block 2023 drives the blocking gear 402 to rotate. The rotation of the blocking gear 402 drives the first gear set 403 to rotate. The first gear set 403 drives the second gear set 404 to rotate, thereby driving the opening and closing gear 4041 to rotate. The rotation of the opening and closing gear 4041 drives the ball valve 3041 to rotate. The design width of the third tooth block 2023 allows the opening and closing gear 4041 to rotate 90 degrees in one movement. Therefore, when the third tooth block 2023 passes through the blocking gear 402, the opening and closing gear 4041 drives the ball valve 3041 to rotate 90 degrees, thereby closing the sample collection tube 304.

[0042] Reference Figure 5 The solvent filling assembly 5 includes a loading box 501. An insertion tube 502 is installed at the front end of the loading box 501. The bottom end of the insertion tube 502 is connected to the inside of the sampling sleeve 101. A gathering ring 503 is installed around the insertion tube 502. A shrinking rod 504 is installed at one end of the gathering ring 503. A shrinking shaft 5041 is opened on the part of the shrinking rod 504 outside the loading box 501.

[0043] In this embodiment, it should be specifically explained that: the user can use the upper end of the insertion tube 502 to penetrate the soft stopper of the solvent bottle 510 to fix the solvent bottle 510, and then rotate the retraction shaft 5041. The retraction shaft 5041 drives the retraction rod 504 to rotate, so that the gathering ring 503 tightens and further fixes the solvent bottle 510; when replacing the solvent bottle 510, simply pull out the empty bottle and install the new solvent bottle 510.

[0044] Reference Figure 6 and Figure 7 Inside the loading box 501, a feeding wheel 505 is installed. A straight-through valve 5051 is installed on the side of the feeding wheel 505 near the insertion tube 502. The straight-through valve 5051 is located inside the insertion tube 502. On the side of the feeding wheel 505 away from the insertion tube 502, there are two parallel stop posts 5052 located at both ends of the feeding wheel 505. A transmission gear 506 is installed on the outer side of the feeding wheel 505. A horizontal pressure rod 5061 is installed on the side of the transmission gear 506 away from the insertion tube 502. The other end of the horizontal pressure rod 5061 is hinged to the parallel stop post 5052. A second conical wheel 509 is installed on the side of the transmission gear 506 away from the insertion tube 502. A first conical wheel 508 is installed below the second conical wheel 509. The first conical wheel 508 meshes with the second conical wheel 509. A discharge gear 507 is installed below the first conical wheel 508.

[0045] In this embodiment, it should be specifically explained that: when the moving shaft 202 is slowly pulled out of the sampling sleeve 101, the first tooth block 2021 will pass the feeding gear 507. The first tooth block 2021 meshes with the feeding gear 507. The movement of the first tooth block 2021 drives the feeding gear 507 to rotate. The rotation of the feeding gear 507 drives the first conical wheel 508 to rotate. The first conical wheel 508 drives the second conical wheel 509 to rotate. The second conical wheel 509 drives the transmission gear 506 to rotate clockwise. The rotation of the transmission gear 506 drives the horizontal pressure rod 5061 to move towards the feed wheel 505. The horizontal pressure rod 5061 pushes the parallel stop column 5052 and applies a downward force to the parallel stop column 5052. The horizontal pressure rod 5061 will drive the feed wheel 505 to rotate clockwise. When the feed wheel 505 rotates ninety degrees, the two... The parallel stop pins 5052 are in a horizontal position, so that the horizontal pressure rod 5061 is blocked by the two parallel stop pins 5052, and the transmission gear 506 stops rotating. The rotation of the feed wheel 505 drives the straight valve 5051 to rotate, the insertion tube 502 is opened, and the solvent in the solvent bottle 510 is released. The transmission gear 506 has a sliding shaft inside, so that when the first tooth block 2021 continues to move backward, it drives the sliding shaft inside the transmission gear 506 to rotate, while the feed wheel 505 stops rotating. The transmission gear 506 has a torsion spring installed inside. When the first tooth block 2021 has completely passed the discharge gear 507, the transmission gear 506 will return to the initial position, driving the straight valve 5051 to close. The sliding shaft has the existing structure. The specific structure and connection method of the sliding shaft inside the transmission gear 506 are not detailed in this embodiment.

[0046] Reference Figure 8 The insertion tube 502 has a central hole baffle 5021 installed inside, a return spring 5022 installed at the upper end of the central hole baffle 5021, and a through valve plate 5023 installed at the upper end of the return spring 5022.

[0047] In this embodiment, it should be specifically explained that: through holes are provided on both sides of the through valve plate 5023, and through holes are provided inside the central baffle plate 5021. When the pressure above the through valve plate 5023 is greater than the pressure below, the through valve plate 5023 will move downward, the return spring 5022 will be compressed, and the solvent inside the solvent bottle 510 will enter the interior of the through valve plate 5023 through the through holes, and then flow through the through holes of the central baffle plate 5021 to the bottom of the central baffle plate 5021 and into the interior of the sampling sleeve 101; when the pressure below the through valve plate 5023 is greater than the pressure above, the through valve plate 5023 will be pushed upward, the return spring 5022 will return to its original length, so that the insertion tube 502 is blocked, preventing the solution inside the sampling sleeve 101 from entering the solvent bottle 510.

[0048] Reference Figure 9The solution receiving assembly 6 includes a solution tube 601, a drip port 602 installed at the bottom of the solution tube 601, a drip valve 6021 installed at the bottom end of the drip port 602, a lifting worm gear 603 installed inside the solution tube 601, a fixing box 607 installed outside the lifting worm gear 603, a transmission crossbar 604 installed outside the fixing box 607, a third gear set 605 installed at the end of the transmission crossbar 604 away from the solution tube 601, and a driven gear 606 installed above the third gear set 605.

[0049] In this embodiment, it should be specifically explained that when the moving shaft 202 slowly moves outward inside the sampling sleeve 101, the movement of the moving shaft 202 drives the second tooth block 2022 to move. When the moving shaft 202 drives the sealing piston 203 past the solution tube 601, the second tooth block 2022 will pass the driven gear 606. The second tooth block 2022 meshes with the driven gear 606. The movement of the second tooth block 2022 drives the driven gear 606 to rotate. The rotation of the driven gear 606 drives the third gear set 605 to rotate. The rotation of the third gear set 605 drives the transmission crossbar 604 to rotate. The rotation of the transmission crossbar 604 causes the lifting worm gear 603 to move downward, causing the solution entering the solution tube 601 to be stirred by the lifting worm gear 603 and flow downward.

[0050] Reference Figure 10 A drive worm gear 6041 is installed at one end of the transmission crossbar 604 near the solution pipe 601. A driven turbine 6042 is installed inside the fixed box 607. The drive worm gear 6041 meshes with the driven turbine 6042. A lifting worm gear 603 is installed inside the driven turbine 6042. Spiral blades 6031 are provided at both ends of the lifting worm gear 603.

[0051] In this embodiment, it should be specifically explained that when the transmission crossbar 604 rotates, the transmission crossbar 604 drives the active worm gear 6041 to rotate, the active worm gear 6041 drives the driven turbine 6042 to rotate, the rotation of the driven turbine 6042 drives the lifting worm gear 603 to rotate and move downward, the movement of the lifting worm gear 603 drives the spiral blade 6031 to move downward, the spiral structure of the spiral blade 6031 makes the sample and solvent mix further, and at the same time accelerates the transfer of the solution inside the sampling sleeve 101 to the interior of the solution tube 601.

[0052] Reference Figure 11 and Figure 12 The pull-out block 201 is equipped with a telescopic spring 702. A trigger button 701 is installed at the end of the telescopic spring 702 away from the pull-out block 201. A telescopic sleeve 703 is provided inside the telescopic spring 702. One end of the telescopic sleeve 703 is fixedly connected to the trigger button 701. The other end of the telescopic sleeve 703 is located inside the sealing piston 203. A liquid discharge port 7031 is provided at the other end of the telescopic sleeve 703.

[0053] In this embodiment, it should be specifically explained that: after the device is used up, the user presses the trigger button 701, the telescopic spring 702 is compressed, the telescopic sleeve 703 is pushed out by the trigger button 701, the liquid outlet 7031 is exposed to the outside of the moving shaft 202, and the disinfectant is released from the liquid outlet 7031 into the inside of the sampling sleeve 101. The disinfectant disinfects the inside of the sampling sleeve 101. Then, the push-pull pull block 201 discharges the disinfectant from the sampling head 303. The telescopic sleeve 703 is an existing structure. The specific structure of the telescopic sleeve 703 and the method of adding disinfectant are not detailed in this embodiment.

[0054] Working principle of the invention:

[0055] The main problem solved by this embodiment is that by opening the moving shaft 202, the blocking component 4 and the solvent filling component 5, this device can make good use of the hydraulic balance principle, so that the device can mix the sample with the solvent in time while collecting the sample, realize the preparation of the sample solution, and maintain the pressure balance inside the sampling sleeve 101, so that the sample solution can be released into the solution collection component 6 for collection.

[0056] Secondly, by opening a heating ring 302, it is beneficial to bring the support shell 301 close to the human body temperature, and at the same time, to keep the collected samples in a temperature environment close to the human body, thus solving the problem that the collected gynecological samples are prone to deterioration.

[0057] The specific steps are as follows: First, the user inserts the upper end of the insertion tube 502 through the soft stopper of the solvent bottle 510, and then rotates the retraction shaft 5041. The retraction shaft 5041 drives the retraction rod 504 to rotate, causing the collection ring 503 to tighten and fix the solvent bottle 510 above the device. Then, the medical staff holds the stabilizing hand support 104 and the pull block 201 to stabilize the device, and then pushes the pull block 201 to expel the air inside the sampling sleeve 101. At this time, the heating ring 302 is activated. The operation keeps the temperature of the support shell 301 constant and close to the human body temperature. Then, the user inserts the support shell 301 and the sampling head 303 into the patient's body, and then slowly pulls out the pull block 201. The movement of the pull block 201 drives the moving shaft 202 to move backward. The moving shaft 202 drives the sealing piston 203 to move backward. Using negative pressure, the fluid secreted by the patient's body is sucked into the sampling head 303 through the sampling port 3031, and then enters the interior of the collection tube 304 from the sampling head 303.

[0058] As the moving shaft 202 moves further backward, the sealing piston 203 moves to the lower end of the insertion tube 502. At this time, the third tooth block 2023 will pass the blocking gear 402. The movement of the third tooth block 2023 drives the blocking gear 402 to rotate. The rotation of the blocking gear 402 drives the first gear set 403 to rotate. The first gear set 403 drives the second gear set 404 to rotate, thereby driving the opening and closing gear 4041 to rotate. The rotation of the opening and closing gear 4041 drives the ball valve 30. 41. Rotate 90 degrees, causing the sample collection tube 304 to be closed by the ball valve 3041; simultaneously, the first toothed block 2021 passes by the feeding gear 507, and the first toothed block 2021 meshes with the feeding gear 507. The movement of the first toothed block 2021 drives the feeding gear 507 to rotate, the rotation of the feeding gear 507 drives the first conical wheel 508 to rotate, the first conical wheel 508 drives the second conical wheel 509 to rotate, and the second conical wheel 509 drives the transmission gear 506 to rotate clockwise. The rotation of the transmission gear 506 drives the horizontal pressure rod 5061 to move closer to the feed roller 505. The horizontal pressure rod 5061 pushes the parallel stop pins 5052 and applies a downward force to them. The horizontal pressure rod 5061 then drives the feed roller 505 to rotate clockwise. When the feed roller 505 rotates 90 degrees, the horizontal pressure rod 5061 is blocked by the two parallel stop pins 5052, the transmission gear 506 stops rotating, and the rotation of the feed roller 505 drives the straight-through valve 50. 51. Rotate, the insertion tube 502 is opened, and the solvent in the solvent bottle 510 is released. At this time, the pressure above the through valve plate 5023 is greater than the pressure below, the through valve plate 5023 moves downward, the return spring 5022 is compressed, and the solvent inside the solvent bottle 510 enters the interior of the through valve plate 5023 through the through hole, and then flows through the through hole of the middle hole baffle plate 5021 to the bottom of the middle hole baffle plate 5021 and enters the interior of the sampling sleeve 101.

[0059] As the moving shaft 202 moves further backward, the sealing piston 203 moves above the solution tube 601. At this time, the second tooth block 2022, driven by the moving shaft 202, passes the driven gear 606 and meshes with it. The movement of the second tooth block 2022 causes the driven gear 606 to rotate. The rotation of the driven gear 606 causes the third gear set 605 to rotate. The rotation of the third gear set 605 causes the transmission crossbar 604 to rotate. The rotation of the transmission crossbar 604 causes the driving worm gear 6041 to rotate. The rotating active worm gear 6041 drives the driven turbine 6042 to rotate. The rotation of the driven turbine 6042 drives the lifting worm gear 603 to rotate and move downward. The movement of the lifting worm gear 603 drives the spiral blade 6031 to move downward, so that the solution entering the solution tube 601 is stirred by the lifting worm gear 603 and flows downward. Finally, the solution enters the interior of the dropper 602. When the user needs to observe or test the sample, he opens the dropper valve 6021 and releases the solution downward onto the slide or other instruments in a titrating manner.

[0060] When the device is finished being used, the user presses the trigger button 701, the telescopic spring 702 is compressed, the telescopic sleeve 703 is pushed out by the trigger button 701, the discharge port 7031 is exposed to the outside of the moving shaft 202, the disinfectant is released from the discharge port 7031 into the inside of the sampling sleeve 101, the disinfectant disinfects the inside of the sampling sleeve 101, and then the push and pull block 201 discharges the disinfectant from the sampling head 303.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
