Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a specimen collection box and a liquid injection method. Background Art

[0002] In the medical field, especially during the prostate biopsy process in urology, the collection and preservation of specimens are crucial steps to ensure the accuracy of diagnosis. Traditional specimen collection methods usually use simple containers or test tubes, which have many problems in practical applications. First, traditional containers lack an effective sealing structure, and are prone to specimen leakage during transportation and preservation, contaminating the samples and affecting the accuracy of subsequent tests. Second, traditional containers cannot achieve automatic sealing during the liquid injection process, and the liquid is likely to splash out, increasing the risk of sample contamination. In addition, the liquid injection process of traditional containers requires manual operation, which is not only inefficient, but also prone to uneven liquid injection or incomplete expulsion of gas in the test tube due to improper operation, affecting the preservation quality of the specimens. These problems seriously affect the collection efficiency and preservation effect of prostate biopsy specimens, causing inconvenience to the operation of medical staff and having an adverse impact on the diagnosis and treatment of patients.

[0003] In the prior art, a patent with the patent number CN108852421A discloses a prostate puncture specimen collection box and its collection method. Although it improves the collection efficiency and accuracy of specimens to a certain extent, it still has some deficiencies. For example, the structure of this collection box is relatively complex, and multiple partitions and through holes are required to achieve the separation of specimen collection grids and the circulation of fixing liquid, which not only increases the manufacturing cost, but also may lead to the risk of fixing liquid leakage during the circulation process. The specimen collection container is prone to leakage during transportation and preservation, cannot be automatically sealed during the liquid injection process, is inefficient, and is prone to uneven liquid injection and incomplete expulsion of gas in the test tube due to improper operation.

[0004] In view of the problems existing in the above prior art, the present invention proposes a specimen collection box and a liquid injection method. Summary of the Invention

[0005] The present invention provides a specimen collection box and a liquid injection method, aiming to solve the problems that traditional specimen collection containers are prone to leakage during transportation and preservation, cannot be automatically sealed during the liquid injection process, are inefficient, are prone to uneven liquid injection due to improper operation, and the gas in the test tube cannot be completely discharged, etc.

[0006] To achieve the above object, the following technical solutions are adopted.

[0007] A specimen collection box includes

[0008] a main bracket, and a plurality of test tube slots are provided in the main bracket;

[0009] Test tubes, with multiple of them respectively placed in the test tube slots;

[0010] A box cover, which is openably and closably installed on the main bracket and is used to seal the main bracket and the test tubes therein;

[0011] The box cover includes a liquid injection port with a cap outside the box cover, multiple sealing plugs at the bottom of the box cover for sealing the corresponding test tubes, liquid addition ports on each of the sealing plugs, a connecting pipeline inside the box cover for connecting the liquid injection port and each of the liquid addition ports, and an automatic sealing mechanism for sealing the liquid addition ports after the test tubes are filled with water.

[0012] Optionally, the automatic sealing mechanism includes an exhaust column that slidably penetrates through the sealing plug and the box cover, and a floating plug at the bottom of the exhaust column for sealing the liquid addition port; a first exhaust hole is provided on the side of the bottom of the exhaust column, a second exhaust hole is provided at the top of the exhaust column, and the first exhaust hole and the second exhaust hole are connected through an exhaust pipeline. When the floating plug floats to the top along with the liquid level, the floating plug cooperates with the sealing plug to seal the liquid addition port and the first exhaust hole.

[0013] Optionally, a rising positioning component is provided on the side of the exhaust column, which is used to make the floating plug continue to rise to a complete sealing state with the sealing plug and be fixed under the action of the rising positioning component when the floating plug rises close to the top.

[0014] Optionally, the rising positioning component includes a first groove provided on the side of the exhaust column, an elastic slider assembly slidably arranged in the first groove, and a limiting part provided inside the box cover and cooperating with the elastic slider assembly. The elastic slider assembly includes a slider and an elastic member. The elastic member connects the bottom of the slider and the bottom of the first groove. The middle of the top of the slider protrudes, and inclined slideways are formed on both sides of the top of the slider; the limiting part includes a second groove and a limiting member provided in the middle of the second groove. The second groove is used for the elastic slider assembly to slide up and down therein, and the limiting member is used to press the slider into the first groove when the elastic slider assembly slides to the position of the limiting member. When the exhaust column continues to slide up and down, the slider crosses the limiting member, and the limiting member provides assistance for the exhaust column in the traveling direction along the inclined slideway.

[0015] Optionally, the top of the floating plug is conical, and the diameter decreases sequentially from bottom to top. A groove matching the top of the floating plug is provided at the bottom of the sealing plug, and the liquid addition port is provided in the groove.

[0016] Optionally, the test tubes are respectively provided with numbers for corresponding to targeted lesion specimens at different positions.

[0017] Optionally, an adjustable exhaust seal is further provided at the top of the exhaust column for sealing the second exhaust hole after the exhaust column reaches a preset position.

[0018] Optionally, a detection module is provided at the bottom of the floating plug for detecting the sample in the test tube in real time and sending it to a monitoring terminal.

[0019] Optionally, a status display module is further provided at the top of the exhaust column for displaying the current status of the floating plug.

[0020] A liquid injection method includes the following steps.

[0021] Align the lid of the specimen collection box with the main bracket, insert the sealing plugs on the lid into the openings of the test tubes in the test tube slots respectively, ensure that the sealing plugs are tightly fitted with the test tube openings, and at the same time make the liquid filling ports on the sealing plugs communicate with the inside of the test tubes. Then close the lid and install it on the main bracket to make the lid tightly fit with the main bracket to complete the installation of the lid.

[0022] Open the cap on the liquid filling port outside the lid to expose the liquid filling port and prepare for the liquid injection operation.

[0023] Inject liquid into the connecting pipeline inside the lid through the liquid filling port. The liquid sequentially passes through the connecting pipeline and the liquid filling port and enters the test tube. As the liquid is injected, the liquid level in the test tube gradually rises, and at the same time, the gas in the test tube is discharged through the first exhaust hole at the bottom of the exhaust column to ensure that the liquid can be smoothly injected into the test tube.

[0024] The liquid level in the test tube rises, and the floating plug floats with the liquid level until the floating plug cooperates with the sealing plug to seal the liquid filling port and the first exhaust hole. At the same time, under the action of the rising positioning assembly, ensure that the floating plug and the sealing plug form a complete sealing state and are fixed to complete the liquid injection and sealing process of the test tube.

[0025] After all the test tubes are filled with liquid and sealed, cover the cap on the liquid filling port again to ensure the sealing performance of the liquid filling port.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] By providing the tight fit between the sealing plug and the test tube and the automatic sealing mechanism, the present invention ensures the sealing performance of the specimen during transportation and storage, effectively preventing liquid leakage and sample contamination.

[0028] The design of the liquid filling port, the connecting pipeline and the liquid filling port enables the liquid to be evenly injected into each test tube. At the same time, the arrangement of the exhaust column and the exhaust hole can effectively discharge the gas in the test tube to ensure that the liquid can be smoothly injected into the test tube, improving the reliability and safety of the liquid injection process.

[0029] The automatic sealing mechanism, through the design of the exhaust column and the floating plug, can automatically seal the liquid filling port and the first exhaust hole after the test tube is filled with liquid, avoiding liquid splashing, and further improving the reliability and safety of the liquid injection process. The first exhaust hole at the bottom of the exhaust column and the second exhaust hole at the top are connected through an exhaust pipeline, ensuring that the gas in the test tube can be smoothly discharged during the liquid injection process, avoiding bubble residue and improving the specimen preservation quality. The design of the rising positioning component ensures that the floating plug can stably form a complete sealing state with the sealing plug during the rising process and be fixed, further enhancing the stability and reliability of the sealing. The cooperative design of the elastic slider component and the limiting part not only enables the floating plug to accurately reach the sealing position, but also provides assistance for the exhaust column in the advancing direction through the inclined slideway, further optimizing the structure and function of the automatic sealing mechanism. The conical design at the top of the floating plug cooperates with the groove at the bottom of the sealing plug, making the seal between the floating plug and the sealing plug tighter and further improving the sealing effect.

[0030] Setting numbers for test tubes respectively can effectively distinguish and mark the targeted lesion specimens at different positions, improving the accuracy and convenience of specimen management and facilitating subsequent analysis and diagnosis.

[0031] The adjustable exhaust seal at the top of the exhaust column can seal the second exhaust hole after the exhaust column reaches the preset position, further optimizing the control of the exhaust process and improving the accuracy of the liquid injection process.

[0032] The detection module at the bottom of the floating plug can detect the sample status in the test tube in real time and send the data to the monitoring terminal. The status display module at the top of the exhaust column can display the status of the floating plug in real time, enabling medical staff to intuitively understand the completion situation of the liquid injection process and further improving the convenience and reliability of the operation.

Detailed implementation manners

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0041] The following detailed descriptions are all exemplary descriptions, aiming to provide further detailed descriptions of the present invention. Unless otherwise specified, all technical terms adopted by the present invention have the same meaning as commonly understood by those of ordinary skill in the art to which the present application belongs. The terms used in the present invention are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention.

[0042] As Figures 1-6 shown, the present invention relates to a specimen collection box, which is particularly suitable for the collection of perineal prostate puncture specimens. Through its unique structural design, the specimen collection box can effectively solve the deficiencies of traditional specimen collection containers in terms of sealing performance and liquid injection process, and improve the reliability and safety of specimen collection, preservation and transportation.

[0043] The specimen collection box includes a main bracket 1, and the main bracket 1 is used to fix and support the test tube 2, and a plurality of test tube slots 11 are arranged inside it. The number of test tube slots 11 can be adjusted according to actual needs. For example, it can be set to 6, 12 or more to meet the collection requirements of different numbers of specimens. The shape and size of each test tube slot 11 are designed to be able to tightly accommodate a test tube 2 to ensure the stability of the test tube 2 in the main bracket 1. The bottom of the test tube slot 11 can be designed to be slightly concave to better fix the bottom of the test tube 2 and prevent the test tube 2 from shaking during transportation.

[0044] The test tube 2 is used to collect and preserve specimens, and its number corresponds to the number of test tube slots 11. The test tube 2 can be made of transparent or translucent materials, such as glass or polypropylene (PP), so that medical staff can intuitively observe the state of the specimens in the test tube 2. Scale lines can be provided on the outer wall of the test tube 2 for accurately measuring the volume of the liquid. In addition, the opening of the test tube 2 can be designed to be slightly flared outward to better cooperate with the sealing plug 302 and improve the sealing effect.

[0045] The lid 3 is pivotally mounted on the main bracket 1 and is used to seal the main bracket 1 and the test tube 2 therein. The shape and size of the lid 3 are designed to closely fit the main bracket 1 to ensure that the opening part of the main bracket 1 can be completely covered in the closed state. A sealing ring can be provided at the edge of the lid 3. The sealing ring can be made of an elastic material, such as silica gel or rubber, to improve the sealing performance between the lid 3 and the main bracket 1. The cross-sectional shape of the sealing ring can be circular, rectangular, trapezoidal, etc., and the specific shape can be selected according to actual needs.

[0046] On the outside of the lid 3, there is a liquid injection port 301 with a cap, and the liquid injection port 301 is used to inject liquid into the connecting pipeline inside the lid 3. The diameter of the liquid injection port 301 can be adjusted according to actual needs. For example, it can be set to 3 mm, 5 mm or larger to meet the requirements of different liquid injection devices. The cap on the liquid injection port 301 can be designed with a screw-on or press-on type to ensure that the liquid injection port 301 can be quickly and reliably sealed after the liquid injection is completed. The material of the cap can be the same as that of the lid 3, such as polypropylene (PP) or polycarbonate (PC), to ensure the overall durability and stability.

[0047] At the bottom of the lid 3, there are multiple sealing plugs 302. Each sealing plug 302 corresponds to a test tube 2 and is used to seal the opening of the test tube 2. The sealing plug 302 can be made of an elastic material, such as silica gel or rubber, to ensure a tight fit with the opening of the test tube 2. The shape and size of the sealing plug 302 are designed to closely match the opening of the test tube 2. For example, it can be designed as a cylindrical or conical shape. A liquid addition port 303 can be provided at the top of the sealing plug 302. The diameter of the liquid addition port 303 can be adjusted according to actual needs. For example, it can be set to 1 mm, 2 mm or larger to meet the requirements of different liquid injection flow rates. The liquid addition port 303 can be designed as a straight hole or an inclined hole, and the specific shape can be selected according to actual needs.

[0048] Inside the lid 3, there is also a connecting pipeline, which is used to connect the liquid injection port and each liquid addition port 303 to ensure that the liquid can be evenly injected into each test tube 2. The connecting pipeline can be made of a flexible material, such as polyethylene (PE) or polyvinyl chloride (PVC), to ensure the smooth flow of the liquid in the pipeline. The layout of the connecting pipeline can be designed as a tree structure or a ring structure, and the specific layout can be selected according to actual needs. During the liquid injection process, the liquid enters the connecting pipeline through the liquid injection port 301 and then enters the test tube 2 through the liquid addition port 303. As the liquid is injected, the liquid level in the test tube 2 gradually rises, and at the same time, the gas in the test tube 2 is discharged through the first exhaust hole 306 at the bottom of the exhaust column 304, ensuring that the liquid can be smoothly injected into the test tube 2.

[0049] The automatic sealing mechanism is a key component of the specimen collection box. Its function is to automatically seal the liquid filling port 303 after the test tube 2 is filled with liquid, preventing the liquid from splashing out. The automatic sealing mechanism includes an exhaust column 304 that slidably penetrates through the sealing plug 302 and the box cover 3, and a floating plug 305 provided at the bottom of the exhaust column 304. A first exhaust hole 306 is provided on the side of the bottom of the exhaust column 304, and a second exhaust hole 307 is provided at the top. The first exhaust hole 306 and the second exhaust hole 307 are connected through an exhaust pipeline. During the liquid injection process, the liquid level in the test tube 2 gradually rises, and the floating plug 305 floats with the liquid level until the floating plug 305 cooperates with the sealing plug 302 to seal the liquid filling port 303 and the first exhaust hole 306. In this way, when the test tube 2 is filled with liquid, the liquid filling port 303 and the first exhaust hole 306 are automatically sealed, avoiding liquid splashing and improving the reliability and safety of the liquid injection process.

[0050] There can be various extensions to the implementation of the automatic sealing mechanism. For example, in addition to the above exhaust column 304 and floating plug 305 structure, other forms of automatic sealing mechanisms can also be adopted. An alternative solution is to use a spring-driven sealing plug 302, and the spring pushes the sealing plug 302 to automatically seal the liquid filling port 303 after the test tube 2 is filled with liquid. Another solution is to use a magnetic or electromagnetic force-driven sealing device to control the movement of the sealing plug 302 through the attraction or repulsion of a magnet or an electromagnet to achieve the automatic sealing function.

[0051] The function of the rising positioning component is to ensure that the floating plug 305 can accurately reach the sealing position during the rising process and remain stable at this position, thereby achieving a reliable sealing effect. The elastic member 310 in the elastic slider 309 assembly can be a spring, and the slider 309 can slide up and down in the first groove 308 under the action of the spring. When the floating plug 305 rises close to the top, the slider 309 is pushed towards the limiting portion under the elastic force of the spring. The limiting member 312 of the limiting portion can be a convex structure. When the slider 309 slides to the position of the limiting member 312, the limiting member 312 presses the slider 309 into the first groove 308, thereby fixing the position of the slider 309. At this time, the floating plug 305 continues to rise under the drive of the exhaust column 304 until it forms a complete seal with the sealing plug 302. When the exhaust column 304 continues to slide up and down, the slider 309 crosses the limiting member 312, and the limiting member 312 provides assistance for the exhaust column 304 in the advancing direction along the inclined slideway at the top of the slider 309 to help the exhaust column 304 reach the sealing position smoothly.

[0052] There can be various extensions to the implementation of the upward positioning component. For example, in addition to the elastic slider 309 component and the limit part structure mentioned above, other forms of positioning components can also be adopted. An alternative solution is to use a ratchet and pawl structure. The ratchet is installed on the exhaust column 304, and the pawl is installed inside the box cover 3. The positioning and fixing of the floating plug 305 are achieved through the cooperation of the ratchet and the pawl. Another solution is to utilize a positioning device driven by hydraulic pressure or air pressure, and control the rising and fixing of the floating plug 305 through the change of hydraulic pressure or air pressure.

[0053] The top of the floating plug 305 is designed to be conical, with the diameter decreasing sequentially from bottom to top, and it cooperates with the groove at the bottom of the sealing plug 302. This conical design enables the floating plug 305 to gradually fit tightly with the groove of the sealing plug 302 during the rising process, ultimately achieving the sealing effect. The liquid filling port 303 is arranged in the groove. Liquid enters the test tube 2 through the liquid filling port 303. As the liquid level rises, the floating plug 305 gradually floats upward until it completely seals the liquid filling port 303 and the first exhaust hole 306. The material of the floating plug 305 can be made of elastic materials, such as silica gel or rubber, to ensure a tight fit with the sealing plug 302. The shape and size of the floating plug 305 can be adjusted according to actual needs. For example, it can be designed as a conical shape, a hemispherical shape, or an elliptical shape, etc. The specific shape can be selected according to the sealing requirements.

[0054] There can also be various extensions to the implementation of the floating plug 305. For example, in addition to the conical floating plug 305 mentioned above, other shaped floating plugs 305 can also be adopted. An alternative solution is to use a floating plug 305 with a multi-layer structure. For example, an elastic membrane is arranged on the outer layer of the floating plug 305, and a rigid support structure is arranged on the inner layer. A better sealing effect is achieved through the deformation of the elastic membrane and the stability of the rigid support structure. Another solution is to use a floating plug 305 made of magnetic materials, and utilize magnetic force to cooperate with the sealing plug 302 during the rising process of the floating plug 305 to further improve the reliability of the seal.

[0055] In order to facilitate the distinction and management of targeted lesion specimens at different positions, the test tubes 2 are respectively provided with numbers. The numbers can be in the form of numbers, letters, or barcodes, etc. The specific form can be selected according to actual needs. The numbers can be directly printed on the outer wall of the test tube 2, or pasted on the test tube 2 in the form of labels. The setting of the numbers enables medical staff to quickly and accurately identify the source of the specimens in each test tube 2, improving the efficiency and accuracy of specimen management.

[0056] There can also be various extensions to the implementation of the identification number of test tube 2. For example, in addition to the above-mentioned direct printing or label pasting methods, other forms of identification numbering methods can also be adopted. One alternative is to use an electronic label, such as a radio frequency identification (RFID) label, to store the identification number information in the electronic label and quickly read the identification number of test tube 2 through a reading device. Another solution is to utilize a color coding system, where different colors are assigned to the targeted lesion specimens at different positions, and the source of the specimens in test tube 2 can be quickly identified through the intuitive distinction of colors.

[0057] An adjustable exhaust seal is also provided at the top of the exhaust column 304 for sealing the second exhaust hole 307 after the exhaust column 304 reaches a preset position. The exhaust seal can adopt a screw-on or press-on design to ensure that the second exhaust hole 307 can be quickly and reliably sealed when needed. The material of the exhaust seal can be the same as that of the cassette cover 3, such as polypropylene (PP) or polycarbonate (PC), to ensure the overall durability and stability.

[0058] There can also be various extensions to the implementation of the exhaust seal. For example, in addition to the above-mentioned screw-on or press-on designs, other forms of exhaust seals can also be adopted. One alternative is to use an elastic membrane seal, which automatically fits onto the second exhaust hole 307 after the exhaust column 304 reaches a preset position to achieve the sealing function. Another solution is to utilize a solenoid valve or pneumatic valve to control the opening and closing of the second exhaust hole 307, and precise exhaust control is achieved through electrical signals or pneumatic signals.

[0059] A detection module is provided at the bottom of the floating plug 305 for real-time detection of the sample state in test tube 2 and sending the data to a monitoring terminal. The detection module can adopt various sensor technologies, such as optical sensors, electrochemical sensors, or biosensors, etc., and the specific type can be selected according to actual needs. The output signal of the detection module can be sent to the monitoring terminal through wired or wireless means, and the monitoring terminal can be a device such as a computer, tablet, or smartphone, etc., for real-time display and recording of the sample state in test tube 2.

[0060] There can also be various extensions to the implementation of the detection module. For example, in addition to the above-mentioned sensor technologies, other forms of detection modules can also be adopted. One alternative is to use an image recognition module, which takes pictures of the sample image in test tube 2 through a camera and then analyzes the sample state through image processing algorithms. Another solution is to utilize an acoustic sensor to judge the sample state by detecting the acoustic wave changes in test tube 2, such as detecting the liquid level height or the uniformity of the sample.

[0061] At the top of the exhaust column 304, a status display module is also provided for displaying the current status of the floating plug 305. The status display module can adopt various display technologies, such as light-emitting diodes (LEDs), liquid crystal displays (LCDs), or organic light-emitting diodes (OLEDs), etc. The specific type can be selected according to actual requirements. The status display module can display information such as the rising position of the floating plug 305, the sealing status, or the liquid injection completion status, enabling medical staff to intuitively understand the completion of the liquid injection process.

[0062] There can also be various extensions to the implementation method of the status display module. For example, in addition to the above display technologies, other forms of status display modules can also be adopted. An alternative solution is to use a mechanical pointer display module, which indicates the status of the floating plug 305 through the position change of the pointer. Another solution is to utilize a sound prompt module, which prompts medical staff about the key status of the liquid injection process through different sound signals, such as the start of liquid injection, the completion of liquid injection, or abnormal sealing, etc.

[0063] Embodiment 2

[0064] A liquid injection method includes the following steps:

[0065] Align the lid 3 of the specimen collection box with the main bracket 1, insert the sealing plugs 302 on the lid 3 into the openings of the test tubes 2 in the test tube slots 11 respectively, ensure that the sealing plugs 302 are tightly fitted with the openings of the test tubes 2, and at the same time make the liquid filling ports 303 on the sealing plugs 302 communicate with the inside of the test tubes 2. Then close and install the lid 3 on the main bracket 1, making the lid 3 and the main bracket 1 tightly fitted to complete the installation of the lid 3. During the installation process, structures such as buckles, threads, or magnetic attraction can be used to fix the lid 3 to ensure its stability during use.

[0066] Open the cap on the liquid injection port 301 outside the lid 3 to expose the liquid injection port 301, and prepare for the liquid injection operation. The cap of the liquid injection port 301 can adopt a screw-on or press-on design to ensure that the liquid injection port 301 can be quickly and reliably sealed after the liquid injection is completed. When opening the cap, a special tool or manual operation can be used, and the specific method can be selected according to the design of the cap.

[0067] Inject liquid into the connecting pipeline inside the lid 3 through the liquid injection port 301. The liquid successively passes through the connecting pipeline and the liquid filling port 303 and enters the test tube 2. As the liquid is injected, the liquid level in the test tube 2 gradually rises, and at the same time, the gas in the test tube 2 is discharged through the first exhaust hole 306 at the bottom of the exhaust column 304 to ensure that the liquid can be smoothly injected into the test tube 2. During the liquid injection process, tools such as syringes, droppers, or automatic liquid injection devices can be used for liquid injection, and the specific method can be selected according to actual requirements.

[0068] The liquid level in the test tube 2 rises, and the floating plug 305 floats up with the liquid level until the floating plug 305 cooperates with the sealing plug 302 to seal the liquid filling port 303 and the first exhaust hole 306. At the same time, under the action of the rising positioning component, the floating plug 305 continues to rise until it forms a complete sealing state with the sealing plug 302 and is fixed, completing the liquid filling and sealing process of the test tube 2. During the automatic sealing process, the rising speed of the floating plug 305 can be adjusted according to the liquid injection speed to ensure the smooth progress of the sealing process.

[0069] After all the test tubes 2 are filled with liquid and sealed, the cap on the liquid filling port 301 is covered again to ensure the sealing performance of the liquid filling port 301. When closing the cap, a special tool or manual operation can be used, and the specific method can be selected according to the design of the cap. After closing the cap, materials such as sealant or tape can be used to further enhance the sealing performance of the liquid filling port 301 to ensure that the liquid does not leak during transportation and storage.
