Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and in particular to a vaginal secretion sampling device. Background Art

[0002] During a gynecological examination, it is usually necessary to sample the secretions in the female vagina. Through sampling and analysis, it can be determined whether there are pathogens such as bacteria, mold, and trichomonas in the vagina, as well as whether there are inflammatory diseases such as vaginitis. This is crucial for the timely diagnosis and treatment of these diseases.

[0003] For example, the Chinese patent with application number 202110261472.2 discloses a gynecological vaginal secretion sampling device, including a guide tube, a clearance hole, a scale, a connecting plate, a clamping mechanism, a first spring, an exhaust mechanism, a placement hole, a blocking mechanism, a mounting hole, a baffle, a connecting hole, a blocking block, a connecting pin, a telescopic mechanism, and a sampling mechanism. The phenomenon that the secretions of the patient's vaginal opening are mixed with the secretions in the vagina can be avoided, that is, the stability of the device in sampling the secretions inside the patient's vagina is ensured.

[0004] However, most existing vaginal secretion sampling devices have simple structures. When multiple sampling is required, the device needs to be inserted into the patient's vagina each time. Multiple insertions of the device not only increase the patient's discomfort, but also easily scratch the patient's vagina, thereby reducing the practicality and safety of the device. Therefore, in view of the above technical problems, a vaginal secretion sampling device is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes a vaginal secretion sampling device, which can perform multiple samplings without repeatedly inserting the device into the vagina, thereby reducing the patient's discomfort, avoiding scratching the patient's vagina, and improving the practicality and safety of the device.

[0006] A vaginal secretion sampling device, comprising:

[0007] The shell comprises a first end and a second end opposite to each other, a cavity is formed in the shell, and a through groove communicating with the cavity is formed on a peripheral side of the first end;

[0008] A closing assembly slidably disposed on the housing to seal or open the through slot; and

[0009] The sampling mechanism comprises a connecting sleeve, a mounting sleeve, a sampling block, a spring first drive component and a second drive component. A coaxial mounting rod is arranged in the cavity, the connecting sleeve is connected to the mounting sleeve, and a coaxial rotatable sleeve is arranged on the mounting rod. A plurality of groups of sampling blocks that can slide radially thereof are evenly arranged on the circumference of the mounting sleeve. The plurality of groups of sampling blocks and the mounting sleeve are all connected with the spring to apply a thrust toward the axis of the mounting sleeve to the sampling blocks. The first drive component is arranged on the outer shell and connected to the connecting sleeve, and is used to drive the connecting sleeve to rotate so that the plurality of groups of sampling blocks can correspond to the through slots in sequence. The second drive component is arranged on the mounting rod and can abut the sampling blocks corresponding to the through slots, and is used to drive the abutted sampling blocks to extend out of the outer shell through the through slots.

[0010] The beneficial effects of the above vaginal secretion sampling device are:

[0011] When taking samples multiple times, sampling can be performed by extending the first end of the shell into the vagina to make the through groove correspond to the sampling position, adjusting the closing component to open the through groove, and then adjusting the second driving component to drive the sampling block to extend out of the shell and contact the vaginal wall. At this time, the spring is in a compressed state, and then, adjusting the second driving component to cancel the resistance to the sampling block. At this time, the reaction force of the spring can drive the sampling block to reset. After the sampling block is reset, the closing component is adjusted to seal the through groove to complete one sampling, and then the shell is moved to make the through groove correspond to another sampling position, and then adjusting the first driving component to drive the connecting sleeve to drive the sampling block to rotate, so that the other sampling block corresponds to the through groove. At this time, repeating the above steps can perform sampling again, and when the shell moves, the sampled sample is always located in the cavity, effectively preventing the sampled sample from being contaminated. The present application can perform multiple sampling without repeatedly inserting the device into the vagina, reducing the patient's discomfort, avoiding scratching the patient's vagina, and improving the practicality of the device and the safety of use.

[0012] In one embodiment, the sampling block includes a mounting block and a sampling cotton block; the mounting block can be slidably arranged on the mounting sleeve along the radial direction of the mounting sleeve, a slot is provided on the outer side of the mounting block, the sampling cotton block is clamped in the slot and protrudes from the mounting block. When the sampling block extends out of the housing through the through slot, the sampling cotton block can contact the patient's vaginal wall, at which time, the sampling cotton block can adhere to the vaginal secretions for sampling, and the sampling cotton block is clamped to the mounting block, which is convenient for the installation and removal of the sampling cotton block, thereby facilitating the replacement of the sampling cotton block.

[0013] In one embodiment, both ends of the mounting block are provided with limit rods, and two groups of limit rods are inserted into the mounting sleeve so as to slide radially along the mounting sleeve, and the two groups of limit rods are sleeved with the spring, and the two ends of the spring respectively abut against the inner side of the mounting sleeve and one end of the limit rod. The stability of the mounting block sliding radially along the mounting sleeve can be improved by providing two groups of limit rods in cooperation with the mounting sleeve, and the spring is sleeved on the limit rod, and the limit rod can guide the expansion and contraction of the spring, thereby improving the service life of the spring.

[0014] In one embodiment, the first driving assembly includes a worm and a worm wheel; the worm is located at the second end, the worm is rotatably arranged in the cavity, and the two ends extend out of the housing, and the worm wheel is coaxially arranged on the connecting sleeve and meshes with the worm. By rotating the worm, the worm rotates and cooperates with the worm wheel to drive the worm wheel to rotate, the worm wheel rotation can drive the connecting sleeve to rotate, the connecting sleeve rotation can drive the installation sleeve to rotate, and the installation sleeve rotation can drive multiple groups of sampling blocks to rotate, so that multiple groups of sampling blocks correspond to the through slots in sequence, and when the sampling blocks correspond to the through slots, stop rotating the worm, the worm and the worm wheel cooperate to fix the worm wheel, thereby fixing the sampling blocks, driving multiple groups of sampling blocks to correspond to the through slots in sequence and fixing the sampling blocks is convenient.

[0015] In one embodiment, at least one end of the worm is provided with a rotating disk, and one end of the rotating disk is provided with multiple groups of indicating grooves evenly arranged along its circumference, and the indicating grooves correspond to the number of the sampling blocks, and the circumferential side of the housing is provided with indicating blocks corresponding to the rotating disk, and when the indicating grooves point to the indicating blocks, the sampling blocks correspond to the through grooves. The worm can be driven to rotate by rotating the rotating disk, and the worm is easy to drive to rotate, and when the rotating disk rotates to make the indicating grooves point to the indicating blocks, the worm drives the sampling blocks to rotate and correspond to the through grooves through the worm wheel, the connecting sleeve and the mounting sleeve, and the sampling blocks are driven to correspond to the through grooves accurately, which is convenient to use.

[0016] In one embodiment, the second driving assembly includes a bidirectional screw, a guide block and a push rod; a guide groove is provided on the mounting rod, the bidirectional screw is arranged parallel to the mounting rod and is rotatably arranged in the guide groove, one end of the bidirectional screw extends from the second end portion to the outside of the outer shell, and two groups of guide blocks that can slide axially along the mounting rod are arranged in the guide groove, the two groups of guide blocks are respectively threadedly connected to the two ends of the bidirectional screw, the push rods are hinged on the two groups of guide blocks, one end of the two groups of push rods are hinged, and can abut against the inner side of the sampling block. By rotating the bidirectional screw and cooperating with the threads of the two groups of guide blocks, the two groups of guide blocks can be driven to move relatively close to each other. The relative movement of the two groups of guide blocks can drive the two groups of push rods to close and rotate. The closing and rotation of the two groups of push rods can resist the sampling block to slide radially along the mounting sleeve, so that the sampling block extends out of the shell through the through groove and contacts the vaginal wall for sampling. At this time, the spring is compressed and contracts. After sampling, the bidirectional screw can be rotated in the opposite direction. The reverse rotation of the bidirectional screw and the two groups of guide block threads can drive the two groups of guide blocks to move relatively away from each other. The relative movement of the two groups of guide blocks can drive the two groups of push rods to rotate outward. The outward rotation of the two groups of push rods can cancel the resistance to the sampling block. At this time, the reaction force of the spring can cause the sampling block to move in the opposite direction, so that the sampling block can be retracted into the cavity through the through groove, driving the sampling block to extend out of the shell for sampling and retract into the cavity after sampling.

[0017] In one embodiment, the closure assembly includes a baffle and a driving rod. A receiving groove connected to the through groove is provided in the inner wall of the shell. The baffle can be slidably arranged in the receiving groove along the axial direction of the shell. The driving rod is arranged at one end of the baffle. One end of the driving rod extends out of the shell from the second end and is provided with a finger buckle. Sliding the driving rod can make the baffle seal or open the through groove. By inserting a finger into the finger buckle and then driving the finger buckle to move away from the shell, the baffle can be driven by the driving rod to move and open the through groove. Conversely, by driving the finger buckle to move close to the shell, the baffle can be driven by the driving rod to move in the opposite direction to seal the through groove, which is convenient for sealing or opening the through groove.

[0018] In one embodiment, a linkage assembly is further included, wherein the linkage assembly connects the drive rod and the bidirectional screw rod. After the drive rod is slid open through the linkage assembly, the sampling block can be driven to extend out of the housing through the through slot. After the drive rod is slid reversely through the linkage assembly, the sampling block can be driven to retract into the cavity through the through slot and then the through slot is sealed. After the through slot is opened by sliding the drive rod to drive the baffle to slide, the drive rod can drive the sampling block to extend out of the housing through the linkage assembly for sampling. After sampling, the drive rod can be slid reversely through the linkage assembly to drive the sampling block to retract into the cavity and drive the baffle to slide reversely to seal the through slot. There is no need to drive the sampling block to extend out of the housing and retract into the cavity separately, which simplifies the sampling operation steps, makes the operation convenient and labor-saving, and further improves the sampling efficiency.

[0019] In one embodiment, the linkage assembly includes a first gear and a second gear; the first gear is rotatably disposed at the second end and is sleeved on the driving rod, and a spiral groove close to the baffle and a straight groove away from the baffle and parallel to the driving rod are opened on the circumference of the driving rod, and the opposite ends of the spiral groove and the straight groove are connected, a guide hemisphere is arranged on the inner side of the first gear, and the guide hemisphere is slidably arranged in the straight groove and the spiral groove, and the second gear is coaxially arranged at the end of the bidirectional screw outside the outer shell, and the second gear is meshed with the first gear. In the process of the driving rod driving the baffle to move and open the through slot, the guide hemisphere moves along the straight slot. When the baffle completely opens the through slot, the guide hemisphere moves into the spiral slot. At this time, the driving rod continues to move through the guide hemisphere and the spiral slot to drive the first gear to rotate. The rotation of the first gear can drive the bidirectional screw to rotate through the second gear. The rotation of the bidirectional screw and the two sets of guide block threads can drive the two sets of guide blocks to move relatively close to each other, thereby driving the sampling block to extend out of the shell through the through slot and contact the vaginal wall for sampling. After sampling, the driving rod is moved in the opposite direction. The driving rod moves in the opposite direction through the guide hemisphere and the spiral slot. The groove cooperation can drive the first gear to rotate in the opposite direction, and the reverse rotation of the first gear can drive the bidirectional screw to rotate in the opposite direction through the second gear. The reverse rotation of the bidirectional screw and the two sets of guide block threads can drive the two sets of guide blocks to move relatively away from each other, thereby eliminating the resistance to the sampling block, so that the sampling block retracts into the cavity under the reaction force of the spring, and while the sampling block retracts into the cavity, the guide hemisphere moves into the straight groove. At this time, the driving rod continues to move in the opposite direction to drive the baffle to seal the through groove, so that the sampling block can be synchronously driven to extend out of the shell after the baffle opens the through groove and to synchronously drive the baffle to seal the through groove after the sampling block retracts into the cavity.

[0020] In one embodiment, the second end is provided with a handle, and a plurality of anti-skid grooves are evenly arranged around the handle. The handle is provided to facilitate holding the device, and the anti-skid grooves are arranged on the handle to improve the stability of the holding device and avoid slipping.

[0038] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0039] See also Figures 1 to 3 In one embodiment, a vaginal secretion sampling device includes a housing 10, a sealing component 20 and a sampling mechanism.

[0040] The housing 10 includes a first end and a second end opposite to each other. A cavity 101 is formed in the housing 10. A through slot 102 is formed around the first end and communicates with the cavity 101. The sealing assembly 20 is slidably disposed on the housing 10 to seal or open the through slot 102. The sampling mechanism includes a connecting sleeve 30, a mounting sleeve 301, a sampling block 302, a spring 303, a first driving component and a second driving component. A coaxial mounting rod 103 is arranged in the cavity 101. The connecting sleeve 30 and the mounting sleeve 301 are connected, and a coaxial rotatable sleeve is arranged on the mounting rod 103. A plurality of groups of sampling blocks 302 that can slide radially thereof are evenly arranged on the circumference of the mounting sleeve 301. The plurality of groups of sampling blocks 302 and the mounting sleeve 301 are all connected with springs 303 to apply a thrust toward the axis of the mounting sleeve 301 to the sampling blocks 302. The first driving component is arranged on the housing 10 and connected to the connecting sleeve 30, and is used to drive the connecting sleeve 30 to rotate so that the plurality of groups of sampling blocks 302 can correspond to the through slots 102 in sequence. The second driving component is arranged on the mounting rod 103, and can abut against the sampling blocks 302 corresponding to the through slots 102, and is used to drive the abutted sampling blocks 302 to extend out of the housing 10 through the through slots 102.

[0041] In the above embodiment, when sampling multiple times, the first end of the housing 10 is extended into the vagina so that the through groove 102 corresponds to the sampling position, and then the sealing component 20 is adjusted to open the through groove 102, and then the second driving component is adjusted to drive the sampling block 302 to extend out of the housing 10 and contact the vaginal wall to perform sampling. At this time, the spring 303 is in a compressed state, and then the second driving component is adjusted to cancel the resistance to the sampling block 302. At this time, the reaction force of the spring 303 can drive the sampling block 302 to reset. After the sampling block 302 is reset, the sealing component 20 is adjusted to seal the through groove 102. That is, one sampling is completed, and then the shell 10 is moved to make the through groove 102 correspond to another sampling point, and then the first driving component is adjusted to drive the connecting sleeve 30 to drive the sampling block 302 to rotate, so that the other sampling block 302 corresponds to the through groove 102. At this time, the above steps are repeated to perform sampling again, and when the shell 10 moves, the sampled sample is always located in the cavity 101, which effectively avoids the sampled sample from being contaminated. The present application does not require the device to be repeatedly inserted into the vagina to perform multiple samplings, reduces the patient's discomfort, avoids scratching the patient's vagina, and improves the practicality of the device and the safety of use.

[0042] Please also read Figure 6 Specifically, in the above embodiment, the connecting sleeve 30 is threadedly connected with a first limiting knob 306, and a first limiting ring groove 1032 is provided on the circumference of the mounting rod 103. The first limiting knob 306 can be rotated to allow one end of the first limiting knob 306 to pass through the first limiting ring groove 1032. The first limiting knob 306 cooperates with the first limiting ring groove 1032 to avoid axial movement of the connecting sleeve 30 during rotation, thereby improving the rotation stability of the connecting sleeve 30. The first limiting knob 306 can be rotated in the opposite direction to separate the first limiting knob 306 from the first limiting ring groove 1032. At this time, the connecting sleeve 30 can be removed from the mounting rod 103, thereby facilitating the assembly and disassembly of the connecting sleeve 30.

[0043] See also Figures 3 to 5 In one embodiment, the sampling block 302 includes a mounting block 3021 and a sampling cotton block 3022; the mounting block 3021 can be radially slidably arranged on the mounting sleeve 301, and a slot 304 is opened on the outer side of the mounting block 3021, and the sampling cotton block 3022 is clamped in the slot 304 and protrudes from the mounting block 3021.

[0044] In the above embodiment, when the sampling block 302 extends out of the shell 10 through the through slot 102, the sampling cotton block 3022 can contact the patient's vaginal wall. At this time, the sampling cotton block 3022 can adhere to the vaginal secretions for sampling, and the sampling cotton block 3022 is snap-connected to the mounting block 3021, which is convenient for the assembly and disassembly of the sampling cotton block 3022, thereby facilitating the replacement of the sampling cotton block 3022.

[0045] On the basis of the above embodiment, further, both ends of the mounting block 3021 are provided with limit rods 305, and two groups of limit rods 305 are inserted on the mounting sleeve 301 so as to slide radially along the mounting sleeve 301. Both groups of limit rods 305 are sleeved with springs 303, and the two ends of the springs 303 respectively abut against the inner side of the mounting sleeve 301 and one end of the limit rods 305. By providing two groups of limit rods 305 and cooperating with the mounting sleeve 301, the stability of the mounting block 3021 sliding radially along the mounting sleeve 301 can be improved, and the spring 303 is sleeved on the limit rods 305, and the limit rods 305 can guide the expansion and contraction of the spring 303, thereby improving the service life of the spring 303.

[0046] See also Figure 2 , Figure 3 and Figure 6 In one embodiment, the first driving assembly includes a worm 40 and a worm wheel 401; the worm 40 is located at the second end, the worm 40 is rotatably arranged in the cavity 101, and both ends extend out of the housing 10, and the worm wheel 401 is coaxially arranged on the connecting sleeve 30 and meshes with the worm 40.

[0047] In the above embodiment, by rotating the worm 40, the worm 40 rotates and cooperates with the worm wheel 401 to drive the worm wheel 401 to rotate, the worm wheel 401 rotates to drive the connecting sleeve 30 to rotate, the connecting sleeve 30 rotates to drive the mounting sleeve 301 to rotate, and the mounting sleeve 301 rotates to drive multiple groups of sampling blocks 302 to rotate, so that it is convenient to make multiple groups of sampling blocks 302 correspond to the through grooves 102 in sequence, and when the sampling blocks 302 correspond to the through grooves 102, stop rotating the worm 40, the worm 40 cooperates with the worm wheel 401 to fix the worm wheel 401, thereby fixing the sampling blocks 302, and driving multiple groups of sampling blocks 302 to correspond to the through grooves 102 in sequence and fixing the sampling blocks 302 is convenient.

[0048] Please also read Figure 1 On the basis of the above embodiment, further, a turntable 402 is provided at least at one end of the worm 40, and a plurality of groups of indicating grooves 4021 are evenly arranged along the circumference of one end of the turntable 402, and the number of the indicating grooves 4021 corresponds to the number of the sampling blocks 302. An indicating block 106 is provided on the circumferential side of the housing 10 corresponding to the turntable 402. When the indicating groove 4021 points to the indicating block 106, the sampling block 302 corresponds to the through groove 102.

[0049] The worm 40 can be driven to rotate by rotating the turntable 402, and the worm 40 is driven to rotate conveniently and labor-savingly. When the turntable 402 rotates to make the indicating slot 4021 point to the indicating block 106, the worm 40 drives the sampling block 302 to rotate corresponding to the through slot 102 through the worm wheel 401, the connecting sleeve 30 and the mounting sleeve 301, and the sampling block 302 is driven to correspond accurately to the through slot 102, which is convenient to use. It can be understood that the transmission ratio of the worm 40 and the worm wheel 401 is 1:1, that is, when the worm 40 rotates one circle, the worm wheel 401 rotates one circle accordingly.

[0050] See also Figure 3 , Figure 4 and Figure 7 In one embodiment, the second driving assembly includes a bidirectional screw 50, a guide block 501 and a push rod 502; a guide groove 1031 is provided on the mounting rod 103, the bidirectional screw 50 is arranged parallel to the mounting rod 103, and is rotatably arranged in the guide groove 1031, one end of the bidirectional screw 50 extends from the second end to the outside of the housing 10, and two groups of guide blocks 501 that can slide axially along the mounting rod 103 are arranged in the guide groove 1031, the two groups of guide blocks 501 are respectively threadedly connected to the two ends of the bidirectional screw 50, and the two groups of guide blocks 501 are hinged with push rods 502, one end of the two groups of push rods 502 is hinged, and can abut against the inner side of the sampling block 302.

[0051] In the above embodiment, the two sets of guide blocks 501 can be driven to move relatively close to each other by rotating the bidirectional screw 50 and engaging with the two sets of guide blocks 501 in threaded engagement. The two sets of guide blocks 501 can be driven to move relatively close to each other and move relatively close to each other, and the two sets of push rods 502 can be driven to close and rotate. The closing and rotation of the two sets of push rods 502 can contact the sampling block 302 and slide radially along the mounting sleeve 301, so that the sampling block 302 extends out of the housing 10 through the through slot 102 and contacts the vaginal wall for sampling. At this time, the spring 303 is compressed and contracted. After sampling, the bidirectional screw 50 is rotated in the opposite direction. The screw rod 50 rotates in the opposite direction and cooperates with the threads of the two groups of guide blocks 501 to drive the two groups of guide blocks 501 to move relatively away from each other. The two groups of guide blocks 501 moving relatively away from each other can drive the two groups of push rods 502 to rotate outward. The two groups of push rods 502 rotating outward can eliminate the interference with the sampling block 302. At this time, the reaction force of the spring 303 can make the sampling block 302 move in the opposite direction, so that the sampling block 302 can be retracted into the cavity 101 through the through groove 102, and the sampling block 302 can be driven to extend out of the housing 10 for sampling and retract into the cavity 101 after sampling.

[0052] Please also read Figure 2On the basis of the above embodiment, further, the closing assembly 20 includes a baffle 201 and a driving rod 202. A receiving groove 104 communicating with the through groove 102 is provided in the inner wall of the housing 10. The baffle 201 can be slidably arranged in the receiving groove 104 along the axial direction of the housing 10. The driving rod 202 is arranged at one end of the baffle 201. The driving rod 202 extends out of the housing 10 from the second end and is provided with a finger buckle 2021. The sliding driving rod 202 can make the baffle 201 seal or open the through groove 102. By inserting a finger into the finger buckle 2021 and then driving the finger buckle 2021 to move away from the housing 10, the baffle 201 can be driven by the driving rod 202 to move and open the through groove 102. Conversely, by driving the finger buckle 2021 to move close to the housing 10, the baffle 201 can be driven by the driving rod 202 to move in the opposite direction to seal the through groove 102, and sealing or opening the through groove 102 is convenient.

[0053] Please also read Figure 8 and Fig. 9 On the basis of the above embodiment, it further includes a linkage component, which connects the drive rod 202 and the bidirectional screw 50. The sliding drive rod 202 can drive the sampling block 302 to extend out of the housing 10 through the through slot 102 after opening the through slot 102 through the linkage component. The reverse sliding drive rod 202 can drive the sampling block 302 to retract into the cavity 101 through the through slot 102 through the linkage component and then seal the through slot 102.

[0054] Specifically, the linkage assembly includes a first gear 60 and a second gear 601; the first gear 60 is rotatably arranged at the second end and is sleeved on the driving rod 202. The driving rod 202 is provided with a spiral groove 203 close to the baffle 201 and a straight groove 204 away from the baffle 201 and parallel to the driving rod 202. The opposite ends of the spiral groove 203 and the straight groove 204 are connected. A guide hemisphere 602 is arranged on the inner side of the first gear 60. The guide hemisphere 602 is slidably arranged in the straight groove 204 and the spiral groove 203. The end of the bidirectional screw 50 located outside the outer shell 10 is coaxially provided with a second gear 601, and the second gear 601 is meshed with the first gear 60.

[0055] In the above embodiment, during the process that the driving rod 202 drives the baffle plate 201 to move and open the through slot 102, the guide hemisphere 602 moves along the straight slot 204. When the baffle plate 201 completely opens the through slot 102, the guide hemisphere 602 moves into the spiral slot 203. At this time, the driving rod 202 continues to move through the guide hemisphere 602 and cooperates with the spiral slot 203 to drive the first gear 60 to rotate. The rotation of the first gear 60 can drive the bidirectional screw 50 to rotate through the second gear 601. The rotation of the bidirectional screw 50 and the threaded cooperation of the two groups of guide blocks 501 can drive the two groups of guide blocks 501 to move relatively close to each other, thereby driving the sampling block 302 to extend out of the housing 10 through the through slot 102 and contact the vaginal wall for sampling. After sampling, the driving rod 202 is moved in the reverse direction. The driving rod 202 moves in the reverse direction through the guide hemisphere 6 02 cooperates with the spiral groove 203 to drive the first gear 60 to rotate in the opposite direction. The reverse rotation of the first gear 60 can drive the bidirectional screw 50 to rotate in the opposite direction through the second gear 601. The reverse rotation of the bidirectional screw 50 and the threaded cooperation of the two sets of guide blocks 501 can drive the two sets of guide blocks 501 to move relatively away from each other, thereby eliminating the resistance to the sampling block 302, so that the sampling block 302 retracts into the cavity 101 under the reaction force of the spring 303, and while the sampling block 302 retracts into the cavity 101, the guide hemisphere 602 moves into the straight groove 204. At this time, the driving rod 202 continues to move in the opposite direction to drive the baffle 201 to seal the through groove 102. There is no need to separately drive the sampling block 302 to extend out of the housing 10 and retract into the cavity 101, which simplifies the sampling operation steps, makes the operation convenient and labor-saving, and further improves the sampling efficiency.

[0056] Please also read Figure 6 Specifically in the above embodiment, a fixing ring groove 107 is provided at the second end of the housing 10, a second limit knob 108 is threadedly connected to the housing 10, a connecting ring 603 is coaxially provided at one end of the first gear 60, the connecting ring 603 is rotatably inserted into the fixing ring groove 107, a second limit ring groove 6031 is provided on the circumference of the connecting ring 603, and rotating the second limit knob 108 can make one end of the second limit knob 108 inserted into the second limit ring groove 6031.

[0057] The coordination of the fixing ring groove 107, the connecting ring 603, the second limiting ring groove 6031 and the second limiting ring groove 6031 can improve the rotation stability of the first gear 60, and the first gear 60 can be disassembled by rotating the second limiting ring groove 6031 in the opposite direction to separate the first gear 60, so the first gear 60 is easy to install and disassemble.

[0058] See also Figure 3 , Figure 4 and Figure 7In one embodiment, a handle 105 is provided at the second end, and a plurality of anti-skid grooves 1051 are evenly provided around the handle 105. The handle 105 is provided to facilitate holding the device, and the anti-skid grooves 1051 provided on the handle 105 can improve the stability of holding the device and avoid slipping.

[0059] The specific implementation of the above-mentioned vaginal secretion sampling device is as follows:

[0060] The first end of the housing 10 is inserted into the vagina so that the through groove 102 corresponds to the sampling position, and then the finger is inserted into the finger button 2021, and then the finger button 2021 is driven to move away from the housing 10 through the driving rod 202 to drive the baffle 201 to move and open the through groove 102. At this time, the guide hemisphere 602 moves along the straight groove 204. When the baffle 201 completely opens the through groove 102, the guide hemisphere 602 moves into the spiral groove 203. At this time, the driving rod 202 continues to move through the guide hemisphere 602 and cooperates with the spiral groove 203 to drive the first gear 6 0 rotates, the first gear 60 rotates to drive the bidirectional screw 50 to rotate through the second gear 601, the bidirectional screw 50 rotates and cooperates with the two sets of guide blocks 501 threads to drive the two sets of guide blocks 501 to move relatively close to each other, the two sets of guide blocks 501 move relatively close to each other to drive the two sets of push rods 502 to close and rotate, the two sets of push rods 502 close and rotate to resist the sampling block 302 to slide radially along the mounting sleeve 301, so that the sampling block 302 extends out of the housing 10 through the through slot 102 and contacts the vaginal wall for sampling, at this time, the spring 303 is compressed and contracts.

[0061] After sampling, the driving rod 202 is moved in the reverse direction. The driving rod 202 moves in the reverse direction and cooperates with the guide hemisphere 602 and the spiral groove 203 to drive the first gear 60 to rotate in the reverse direction. The reverse rotation of the first gear 60 can drive the bidirectional screw 50 to rotate in the reverse direction through the second gear 601. The reverse rotation of the bidirectional screw 50 and the threaded cooperation of the two groups of guide blocks 501 can drive the two groups of guide blocks 501 to move away from each other. The two groups of guide blocks 501 move away from each other and drive the two groups of push rods 502 to rotate outward. The outward rotation of the two groups of push rods 502 can cancel the resistance to the sampling block 302. At this time, the reaction force of the spring 303 can make the sampling block 302 move in the reverse direction, so that the sampling block 302 can be retracted into the cavity 101 through the through slot 102, and while the sampling block 302 is retracted into the cavity 101, the guide hemisphere 602 moves into the straight slot 204. At this time, the driving rod 202 continues to move in the reverse direction to drive the baffle 201 to seal the through slot 102, thereby completing a sampling. When sampling, there is no need to separately drive the sampling block 302 to extend out of the housing 10 and retract into the cavity 101, which simplifies the sampling operation steps, makes the operation convenient and labor-saving, and further improves the sampling efficiency.

[0062] When sampling again, the housing 10 is moved to make the through slot 102 correspond to another sampling location, and then the turntable 402 is rotated to drive the worm 40 to rotate. The rotation of the worm 40 cooperates with the worm gear 401 to drive the worm gear 401 to rotate. The rotation of the worm gear 401 can drive the connecting sleeve 30 to rotate. The rotation of the connecting sleeve 30 can drive the installation sleeve 301 to rotate. The rotation of the installation sleeve 301 can drive the multiple groups of sampling blocks 302 to rotate. When the turntable 402 rotates to make the indicating slot 4021 point to the indicating block 106, the sampling block 302 rotates to correspond to the through slot 102 and abuts against the two groups of top rods 502. 6, the sampling block 302 can be accurately matched with the through slot 102, and it is easy to use. When the sampling block 302 is matched with the through slot 102, the rotating disk 402 is stopped to stop the worm 40, and the worm 40 and the worm wheel 401 cooperate to fix the sampling block 302, and then the driving rod 202 is repeatedly moved to perform sampling again. When the housing 10 moves, the sample is always located in the cavity 101, which effectively avoids the contamination of the sample. Multiple sampling can be performed without repeatedly inserting the device into the vagina, which reduces the patient's discomfort and avoids scratching the patient's vagina, thereby improving the practicality of the device and the safety of use.
