Description

Technical Field

[0001] The invention relates to the technical field of sampling instruments, and in particular to a vaginal secretion sampling device for gynecological clinics. Background Art

[0002] Vaginal secretions are a mixture of vaginal mucosal exudates, cervical canal secretions, and endometrial gland secretions. Their production is closely related to the activity of estrogen. During a woman's menstrual cycle, when the ovaries are about to ovulate, that is, in the middle of the menstrual cycle, the cervical glands become particularly active and secrete a large amount of fluid. At this time, vaginal secretions usually appear transparent, slightly sticky, and have a texture similar to egg white. Before and after menstruation, due to the influence of pelvic congestion, the exudate of the vaginal mucosa will increase.

[0003] During gynecological examinations, medical staff often use cotton swabs to collect vaginal secretions from women. They gently insert the cotton swab into the vagina, take out the secretions, and then put the cotton swab into an open plastic bottle or test tube for inspection. However, this traditional sampling method has some problems. Since the cotton swab is stored in an open plastic bottle, the object to be inspected in the bottle is easily contaminated by the external environment during the inspection process, which will undoubtedly affect the final test results.

[0004] In addition, this sampling method is not very convenient in actual operation. More importantly, the existing sampling methods often have difficulty reaching the deeper parts of the vagina, which makes direct sampling extremely difficult. For those secretions located deep in the vagina, traditional sampling methods often cannot meet the needs, which undoubtedly increases the difficulty of sampling and limits the scope and accuracy of gynecological examinations.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Example 1 Reference Figure 1-6 A vaginal secretion sampling device for gynecological clinical practice comprises a sampling handheld part 1, and two curved connecting arms 2 fixed at one end of the sampling handheld part 1, one end of the two curved connecting arms 2 is fixed with a reinforcement block 3, a sampling mechanism is assembled between the sampling handheld part 1 and the reinforcement block 3, the sampling mechanism comprises a positioning cylinder 4, a docking cylinder 5, a spherical protrusion cavity 6, a recessed portion 7 and a conical guide tube 8, a positioning cylinder 4 is fixed to the inner side of the reinforcement block 3, one end of the positioning cylinder 4 is fixed to the sampling handheld part 1, and the other end of the positioning cylinder 4 is connected to the docking cylinder 5 by a thread, a spherical protrusion cavity 6 is integrally fixed to the end of the docking cylinder 5 away from the positioning cylinder 4, a recessed portion 7 is arranged between the spherical protrusion cavity 6 and the docking cylinder 5, and a plurality of conical guide tubes 8 are evenly fixed on the inner side of the recessed portion 7.

[0023] The sampling mechanism also includes a sampling cup 9, a flow guide port 10 and an air inflation tube 11. The flow guide port 10 is fixed to one end of the inner side of the docking tube 5 and close to the conical flow guide tube 8. One end of the flow guide port 10 is threadedly connected to the air inflation tube 11, and one end of the air inflation tube 11 is threadedly connected to the sampling cup 9. A plurality of collecting cavities are arranged on the inner side of the sampling cup 9. The collecting cavities are convenient for storing multiple portions of vaginal secretions for medical staff to take for inspection.

[0024] The diameter of the end of the conical guide tube 8 close to the guide port 10 is smaller than the diameter of the end away from the guide port 10, and one end of the conical guide tube 8 is inclined toward the inner side of the guide port 10. Through the setting of the conical guide tube 8, vaginal secretions flow into the guide port 10 through the conical guide tube 8, and it is not easy to generate backflow from the end of the conical guide tube 8 close to the guide port 10.

[0025] An auxiliary mechanism is installed between the sampling handheld part 1 and the sampling cup 9, and the auxiliary mechanism is used to adjust the telescopic distance of the air blowing tube 11. The auxiliary mechanism includes a guide assembly and a transmission assembly. A connecting positioning rod 12 is fixed to the inner side of the sampling handheld part 1, and the connecting positioning rod 12 is fixed to one end of the positioning tube 4. One end of the connecting positioning rod 12 is equipped with a guide assembly, and the inner side of the guide assembly is equipped with a transmission assembly.

[0026] The guide assembly includes a guide sleeve 13, a central transmission rod 14, an internally connected carrying cavity 15, a sleeve guide tube 16, a limiting protrusion 17, a spiral limiting strip opening 18 and an obstruction opening 34. The outer side of the connecting positioning rod 12 is equipped with a guide sleeve 13, one end of which is fixed with the central transmission rod 14, the inner side of the connecting positioning rod 12 is provided with an internally connected carrying cavity 15, one end of which is fixed with a sleeve guide tube 16, the sleeve guide tube 16 is slidably connected to the inner side of the guide sleeve 13, and the sleeve guide tube 16 is connected to the inner side of the guide sleeve 13. A spiral limiting strip opening 18 is provided on the outer side, and the inner side of the spiral limiting strip opening 18 is slidably connected to the limiting protrusion 17. An obstruction opening 34 is provided on the inner end of the spiral limiting strip opening 18. The obstruction opening 34 is communicated with the spiral limiting strip opening 18, and the obstruction opening 34 is slidably connected to the limiting protrusion 17. An arc protrusion is provided at the connection between the obstruction opening 34 and the spiral limiting strip opening 18, so that the limiting protrusion 17 can only be separated from the obstruction opening 34 when the first connecting spring 21 is twisted when the central transmission rod 14 is pressed for the second time.

[0027] The transmission assembly includes a force transmission rod 19, a limit cutout 20, a first connection spring 21 and a rotating head 22. The inner side of the connection positioning rod 12 is slidably connected with the force transmission rod 19. One end of the force transmission rod 19 is engaged with the sampling cup 9. The outer side of the force transmission rod 19 is fixed with a limit cutout 20. The limit cutout 20 is slidably connected with the internal carrying cavity 15. One side of the limit cutout 20 is fixed with a first connection spring 21. The first connection spring 21 is sleeved on the outer side of the force transmission rod 19. The end of the force transmission rod 19 away from the sampling cup 9 is A rotating head 22 is fixed, and the rotating head 22 is slidably connected to the inner side of the sleeve guide tube 16. The limiting protrusion 17 is fixed to the rotating head 22, and the rotating head 22 is rotatably connected to the central transmission rod 14. When the central transmission rod 14 is pressed, the central transmission rod 14 pushes the rotating head 22 to move along the inner side of the sleeve guide tube 16. Because the rotating head 22 is rotatably connected to the central transmission rod 14, and the limiting protrusion 17 is slidably connected to the spiral limiting strip 18, the limiting protrusion 17 can drive the rotating head 22 to generate a certain rotation when moving.

[0028] Example 2 Embodiment 1 is further optimized, specifically, as Figure 2 and Figure 7 As shown, a limiting mechanism is assembled between the sampling handheld part 1 and the central transmission rod 14 , and the limiting mechanism is used to position the central transmission rod 14 .

[0029] The limiting mechanism includes an L-shaped connecting arm 23, an auxiliary mounting plate 24, a matching active opening 25, a toggle head 26, a connecting pin 27, a push-pull rod 28, a second connecting spring 29, a force application opening 30, an active joint 31, a force guiding inclined surface 32 and a connecting opening 33. A plurality of L-shaped connecting arms 23 are evenly fixed at one end of the sampling handheld portion 1 and deviate from the position of the connecting positioning rod 12. One end of the plurality of L-shaped connecting arms 23 is fixed with an auxiliary mounting plate 24. A matching active opening 25 is provided at the bottom of the auxiliary mounting plate 24. A toggle head 26 is rotatably connected to the inner side of the matching active opening 25 through a pin. A connecting pin 27 is fixed to the top of the toggle head 26. A push-pull rod 28 is mounted on the top of the connecting pin 27. The push-pull rod 28 is slidably connected to the inner side of the auxiliary mounting plate 24. A second connecting spring 29 is fixed to one end of the push-pull rod 28. One end of the second connecting spring 29 is fixed to the inner side of the auxiliary mounting plate 24. A loading force-applying opening 30 corresponding to the position of the connecting pin 27 is provided at the bottom, and the loading force-applying opening 30 is slidably connected to the connecting pin 27. One end of the mounting auxiliary plate 24 is rotatably connected to two movable joints 31 which are symmetrically arranged up and down through a pin. A force-guiding inclined surface 32 is provided on the side where the two movable joints 31 are close to each other, and the force-guiding inclined surfaces 32 are slidably connected to one end of the push-pull rod 28. A connecting opening 33 corresponding to the position of the movable joint 31 is provided at one end of the center transmission rod 14, and the connecting opening 33 is transitionally matched with the movable joint 31. When it is necessary to release the movement limit of the center transmission rod 14, the toggle head 26 is pulled so that the toggle head 26 drives the connecting pin 27 to rotate, and then the connecting pin 27 pushes the push-pull rod 28 to move through the loading force-applying opening 30. Under the guidance of the force-guiding inclined surface 32, the push-pull rod 28 pushes the movable joint 31 to rotate, and finally separates from the connecting opening 33.

[0030] From the above, we can know that: The present invention is directed to a technical problem: During a gynecological examination, medical staff often use cotton swabs to collect vaginal secretions from women. They gently insert the cotton swab into the vagina, then take out the secretions, and then put the cotton swab into an open plastic bottle or test tube for inspection. However, this traditional sampling method has some problems. Since the cotton swab is stored in an open plastic bottle, the objects to be inspected in the bottle are easily contaminated by the external environment during the inspection process, which will undoubtedly affect the final test results. In addition, this sampling method is not very convenient in actual operation. More importantly, the existing sampling methods often find it difficult to reach the deeper parts of the vagina, which makes direct sampling extremely difficult. For those secretions located deep in the vagina, traditional sampling methods often cannot meet the needs, which undoubtedly increases the difficulty of sampling and limits the scope and accuracy of gynecological examinations; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solution is: During use, the medical staff first holds the sampling handheld part 1, and then presses the central transmission rod 14 once, so that the central transmission rod 14 pushes the force guide sleeve 13 and the rotating head 22 to move. Because the limiting protrusion 17 is slidably connected with the spiral limiting strip opening 18 and the obstruction opening 34, the force transmission rod 19 is slidably connected with the inner side of the connecting positioning rod 12, and the limiting notch 20 is slidably connected with the internal carrying cavity 15, the first connecting spring 21 can be twisted and squeezed and contracted, so that the limiting protrusion 17 moves along the inner side of the spiral limiting strip opening 18 until the limiting protrusion 17 enters the obstruction opening 34, and the force transmission rod 19 pushes the sampling cup 9 to squeeze the air tube 11 to contract. At this time, the sampling cup 9 is in a negative pressure state. Then, the spherical protrusion cavity 6 and the docking tube 5 are placed in the patient's vagina, and the central transmission rod 14 is pressed again. At this time, because the first connecting spring 21 is in a twisted and squeezed contraction state, when the limiting protrusion 17 is pressed to the bottom of the obstruction opening 34, the first connecting spring 21 is reset, rebounded and rotated, so that the limiting protrusion 17 is separated from the obstruction opening 34, and then the limiting protrusion 17 slides and resets along the spiral limiting strip opening 18, so that the force transmission rod 19 pulls the sampling cup 9 to move and reset. Since the recessed portion 7 is between the docking tube 5 and the spherical protrusion cavity 6, and It is concave in shape. When it comes into contact with vaginal secretions, the vaginal secretions flow along the surface of the concave portion 7 to the inner side of the concave portion 7. Under the action of the negative pressure in the sampling cup 9, the vaginal secretions eventually flow into the sampling cup 9 through the multiple conical guide tubes 8, the guide port 10 and the air inflation tube 11, completing the collection 1 of the vaginal secretions. Finally, the positioning tube 4 and the docking tube 5 are separated, and the sampling cup 9 is separated from the air inflation tube 11. The sampling cup 9 can be removed separately for inspection. During this process, the sampling cup 9 is not subject to secondary contamination by medical devices such as cotton swabs, making the inspection result more accurate.

[0031] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects: 1. The present invention adopts the structural design of the sampling mechanism and the auxiliary mechanism, so that when sampling vaginal secretions from patients, the device can penetrate deep into the vagina, thereby easily obtaining secretion samples that are difficult to reach with traditional methods, and can absorb vaginal secretions by pressing the trachea 11, so that the vaginal secretions can be stored in the sampling cup 9, which is convenient for subsequent direct sample delivery and inspection, greatly improving the accuracy of gynecological examinations and patient experience.

[0032] 2. The present invention uses the structural design of the limiting mechanism to enable the device to locate the position of the central transmission rod 14, thereby avoiding ambiguity about the current state of the air inflation tube 11 during operation, which is convenient for use.
