Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a sampler for routine leukorrhea detection. BACKGROUND

[0002] Leukorrhea is a mixture of vaginal mucosa exudates, cervical canal and endometrial gland secretions, and routine leukorrhea examination is one of the most common gynecological laboratory examinations, which is mainly used to determine whether a woman has abnormal leukorrhea and reproductive tract inflammation. At the same time, routine examination of leukorrhea has a very important clinical basis for the diagnosis of uterine cavity lesions in women. The traditional leukorrhea sampling operation is generally as follows: when the patient has no sexual life, the doctor will use a cotton swab to wipe the sampling at the labia minora of the vaginal orifice; when the patient has sexual life, the doctor will use a cotton swab to explore the vagina and wipe the sampling on the vaginal wall. For some young female patients accompanied by parents, they may not be willing to admit that they have sexual life. Therefore, in order to avoid inaccurate sampling, the existing doctors generally use a speculum to open the vagina, and then use their hands to hold the cotton swab to extract it into the woman's vagina. However, due to the limited length of the cotton swab, the doctor's hand will also contact the patient's vagina when the cotton swab is inserted into the woman's vagina. In addition, the cotton swab lacks protection after sampling, and is in contact with the outside world for a long time during the delivery process, which is easy to contaminate the sample and affect the test result, and the practicality is poor. Therefore, we propose a sampler for routine leukorrhea detection. SUMMARY

[0003] The purpose of the present application is to provide a sampler for routine leukorrhea detection to solve the problems raised in the background.

[0004] To achieve the above purpose, the present application provides the following technical scheme: a sampler for routine leukorrhea detection, comprising a sampling rod, further comprising a semicylindrical protective shell, the semicylindrical protective shell is provided with two pieces of semicylindrical protective shell which are closed to form a hollow cylinder to wrap the sampling rod;

[0005] A driving assembly is arranged on the semicylindrical protective shell, which drives the two semicylindrical protective shells to move and open the patient.

[0006] A linkage assembly is arranged in the two semicylindrical protective shells and connected with the sampling rod, which moves the semicylindrical protective shell and drives the sampling rod to extend out of the semicylindrical protective shell by the linkage assembly.

[0007] An adjustment component is housed within the two semi-cylindrical protective shells. This component drives the sampling rod to deflect for sampling. Unlike existing technologies, in practical use, the snap-fit ​​semi-cylindrical protective shells are inserted into the patient's vagina. A drive component then moves and unfolds the two shells, opening the vagina. Simultaneously, a linkage component extends the sampling rod out of the shells. The adjustment component then adjusts the angle of the sampling rod to collect vaginal discharge. This method is simple and convenient. Furthermore, the adjustment mechanism prevents medical personnel from touching the patient's body. Conversely, retracting the semi-cylindrical protective shells retracts the sampling rod back inside, preventing contamination during sample collection and ensuring accurate test results.

[0008] Preferably, the driving assembly includes a hollow shaft 1 disposed at one end of the semi-cylindrical protective shell, an arc plate 1 disposed on one of the hollow shaft 1, an arc plate 2 disposed on the other hollow shaft 2, a shaft 2 disposed on the arc plate 1, and the shaft 2 passing through the arc plate 2. Squeezing the arc plate 1 and the arc plate 2 drives the two semi-cylindrical protective shells to move.

[0009] The first and second arc-shaped plates are provided with locking components, which are used to limit and fix the first and second arc-shaped plates.

[0010] Preferably, a limiting plate is provided at one end of the second shaft, and a torsion spring is sleeved on the second shaft. When the two semi-cylindrical protective shells are opened, the torsion spring is subjected to force and torsion to provide self-recovery capability for the two semi-cylindrical protective shells.

[0011] Preferably, the linkage component includes a movable ring disposed between the two semi-cylindrical protective shells, the movable ring being connected to the sampling rod, and two shafts three being symmetrically disposed on the movable ring, and each of the two semi-cylindrical protective shells being provided with a shaft four, with a connecting rod disposed between the shaft four and one of the shafts three, so that moving the semi-cylindrical protective shells causes the movable ring to move.

[0012] Preferably, the adjustment assembly includes a rotating ring disposed on one side of the moving ring, a shaft five disposed inside the rotating ring, an adjustment rod disposed on the shaft five, and one end of the adjustment rod being connected to the sampling rod, so that moving the adjustment rod causes the sampling rod to deflect.

[0013] Preferably, the rotating ring is provided with two shafts, and each of the two shafts is provided with an arc-shaped rod. A guide rod is provided inside the semi-cylindrical protective shell, and the guide rod slides through one end of the arc-shaped rod. Moving the semi-cylindrical protective shell uses the arc-shaped rod to drive the sampling rod to rotate.

[0014] Preferably, the semi-cylindrical protective shell has a placement groove, and an elastic airbag is placed in the placement groove. One end of the adjusting rod is hollow, and the sampling rod is also hollow with one end located inside the adjusting rod. A soft conduit is provided on one side of the elastic airbag, and one end of the soft conduit passes through the semi-cylindrical protective shell and is connected to the adjusting rod.

[0015] Preferably, the locking assembly includes an arc-shaped support plate 1 disposed on one side of the arc-shaped plate 1, the arc-shaped support plate 1 having a plurality of slots 1 evenly spaced on it, and the arc-shaped plate 2 having a bolt, which is rotated to insert one end into the slot 1 to lock the arc-shaped plate 1.

[0016] Preferably, the locking assembly includes an arc-shaped support plate 2 disposed on one side of the arc-shaped plate 1. The arc-shaped support plate 2 has a plurality of slots 2 evenly spaced on it, and a hollow column is disposed on the arc-shaped plate 2. A sliding pin is disposed inside the hollow column. One end of the sliding pin passes through the arc-shaped plate 2 and is located in the slot 2 to lock the arc-shaped plate 1.

[0017] The hollow column has a sliding groove, and one end of the sliding pin has a rectangular protrusion. One end of the rectangular protrusion slides through the sliding groove, and one end of the sliding pin has a spring. Moving the rectangular protrusion causes the sliding pin to be pulled out of the second slot, and at the same time the spring is compressed to provide the sliding pin with self-recovery capability.

[0018] Preferably, one end of the sliding pin is designed with a bevel.

[0019] The present invention has at least the following beneficial effects:

[0020] Unlike existing technologies, in actual use, the snap-fit ​​semi-cylindrical protective shell is inserted into the patient's vagina. Then, the drive component moves and unfolds the two semi-cylindrical protective shells, thus opening the vagina. At the same time, the linkage component moves the sampling rod out of the semi-cylindrical protective shell. The adjustment component then adjusts the angle of the sampling rod to collect vaginal discharge. This is simple and convenient. The adjustment rod also prevents medical staff from touching the patient's body. Conversely, retracting the semi-cylindrical protective shell moves the sampling rod back into the shell, thus preventing the sampling rod from being contaminated during the test and ensuring the accuracy of the test results.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1-5 The present invention provides a technical solution: a sampler for routine testing of vaginal discharge, including a sampling rod 1, which is composed of a hollow plastic tube and a cotton ball at the head, similar to a conventional cotton swab, and also includes a semi-cylindrical protective shell 2, which is provided with two pieces that fit together to form a hollow column 66 to wrap the sampling rod 1.

[0032] Drive component 3 is set on the semi-cylindrical protective shell 2. Drive component 3 drives the two semi-cylindrical protective shells 2 to move and open the patient's vagina.

[0033] Linkage component 4 is set inside two semi-cylindrical protective shells 2 and connected to the sampling rod 1. Moving the semi-cylindrical protective shell 2 and using the linkage component 4 to drive the sampling rod 1 to extend out of the semi-cylindrical protective shell 2 makes it convenient for medical staff to perform sampling operations.

[0034] Adjustment component 5 is installed inside two semi-cylindrical protective shells 2. Adjustment component 5 drives the sampling rod 1 to deflect for sampling. The semi-cylindrical protective shells 2 are then inserted into the patient's vagina. Drive component 3 moves and unfolds the two semi-cylindrical protective shells 2, thus opening the vagina. Simultaneously, linkage component 4 drives the sampling rod 1 to extend out of the semi-cylindrical protective shells 2. Adjustment component 5 then adjusts the angle of the sampling rod 1 to collect vaginal discharge. This process is simple and convenient. The adjustment rod 53 prevents medical staff from touching the patient's body. Conversely, retracting the semi-cylindrical protective shells 2 retracts the sampling rod 1 back into the shells, preventing contamination during sample collection and ensuring the accuracy of the test results.

[0035] The drive assembly 3 includes a hollow shaft 31 fixedly connected to one end of the semi-cylindrical protective shell 2. An arc plate 32 is rotatably connected to the hollow shaft 31 via a bearing. An arc plate 33 is rotatably connected to the hollow shaft 34 via a bearing. The arc plate 34 is fixedly connected to the arc plate 32. The arc plate 34 passes through the arc plate 33 and is rotatably connected to it via a bearing. Squeezing the arc plate 32 and the arc plate 33 causes the two semi-cylindrical protective shells 2 to move and open the patient's vagina.

[0036] A locking component 35 is provided on the first arc plate 32 and the second arc plate 33. The locking component 35 is used to limit and fix the first arc plate 32 and the second arc plate 33. So when the medical staff uses the semi-cylindrical protective shell 2 to open the patient's vagina, the locking component 35 can be used to lock the semi-cylindrical protective shell 2, thereby facilitating the operation of the medical staff.

[0037] One end of shaft 2 34 is fixedly connected to a limiting plate 36, and a torsion spring 37 is sleeved on shaft 2 34. The two ends of the torsion spring 37 are fixedly connected to the limiting plate 36 and the arc-shaped plate 2 33 respectively. Thus, in the initial state of the torsion spring 37, the two semi-cylindrical protective plates are in a closed state, thereby opening the two semi-cylindrical protective shells 2. At the same time, the torsion spring 37 is subjected to force and torsion to provide self-recovery capability for the two semi-cylindrical protective shells 2, which is simple and convenient.

[0038] The linkage component 4 includes a movable ring 41 disposed between two semi-cylindrical protective shells 2. The movable ring 41 is connected to the sampling rod 1, and two shafts 42 are symmetrically fixedly connected to the movable ring 41. Each of the two semi-cylindrical protective shells 2 is rotatably connected to a shaft 43 via bearings. A connecting rod 44 is disposed between the shaft 43 and one of the shafts 42. One end of the connecting rod 44 is fixedly connected to the shaft 43, and the other end is rotatably connected to the shaft 42 via bearings. Moving the semi-cylindrical protective shell 2 drives the connecting rod 44 to move, thereby driving the movable ring 41 to move, and in turn driving the sampling rod 1 to move.

[0039] The adjustment assembly 5 includes a rotating ring 51 disposed on one side of the moving ring 41. The rotating ring 51 is rotatably connected to the moving ring 41, and the moving ring 41 can drive the rotating ring 51 to move. A shaft 52 is rotatably connected inside the rotating ring 51 through a bearing. An adjustment rod 53 is fixedly connected to the shaft 52, and one end of the adjustment rod 53 is connected to the sampling rod 1. Moving the adjustment rod 53 causes the sampling rod 1 to deflect, thereby causing the sampling rod 1 to deflect for sampling, thereby increasing the sampling range.

[0040] Two shafts 54 are fixedly connected to the rotating ring 51, and each shaft 54 ​​is rotatably connected to an arc-shaped rod 55 via bearings. A guide rod 56 is fixedly connected inside the semi-cylindrical protective shell 2, and the guide rod 56 slides through one end of the arc-shaped rod 55 to guide the relative movement of the rotating ring 51. At the same time, the movement of the semi-cylindrical protective shell 2 drives the sampling rod 1 to rotate using the arc-shaped rod 55. Thus, when the sampling rod 1 is retrieved after collection, it can be driven to rotate synchronously, thereby driving it to rotate synchronously to wrap around the highly fluid leukorrhea, thus preventing the collected leukorrhea from dripping back into the vagina, causing a reduction in the sample volume, and thus improving the sampling effect.

[0041] The semi-cylindrical protective shell 2 has a placement groove 57, in which an elastic airbag 58 is fixedly connected. One end of the adjusting rod 53 is hollow, and the sampling rod 1 is also hollow with one end located inside the adjusting rod 53, so that the sampling rod 1 can be removed from the adjusting rod 53 and the main body of the device can be reused, thereby improving its practicality. A soft catheter 59 is conductively connected to one side of the elastic airbag 58, and one end of the soft catheter 59 passes through the semi-cylindrical protective shell 2 and is conductively connected to the adjusting rod 53. After being inserted into the semi-cylindrical protective shell 2, the patient's vagina is opened, and the elastic airbag 58 is squeezed to deform it. When the sampling rod 1 is retrieved after collection, the semi-cylindrical protective shell 2 is released, and the elastic airbag 58 returns to its original position, thereby sucking out the air in the sampling rod 1, thereby creating negative pressure at the end of the sampling rod 1, so that the vaginal discharge adheres tightly to the sampling rod 1, thereby further preventing the collected vaginal discharge from dripping back into the vagina, resulting in a reduction in the sample volume, and thus improving the sampling effect.

[0042] The locking assembly 35 includes an arc-shaped support plate 61 fixedly connected to one side of the arc-shaped plate 32. The arc-shaped support plate 61 has multiple slots 62 evenly spaced on it, and the arc-shaped plate 33 is connected to a bolt 63 by a thread. Rotating the bolt 63 allows one end of it to be inserted into the slot 62 to lock the arc-shaped plate 32.

[0043] The locking assembly 35 includes an arc-shaped support plate 64 fixedly connected to one side of the arc-shaped plate 32. The arc-shaped support plate 64 has a plurality of slots 65 evenly spaced on it. A hollow column 66 is fixedly connected to the arc-shaped plate 33. A sliding pin 67 is slidably connected inside the hollow column 66. One end of the sliding pin 67 passes through the arc-shaped plate 33 and is located in the slot 65 to lock the arc-shaped plate 32.

[0044] During the normal operation of the sampler used for routine vaginal discharge testing, the snap-fit ​​semi-cylindrical protective shell 2 is inserted into the patient's vagina. Then, by pinching the arc-shaped plate 32 and arc-shaped plate 33, the two semi-cylindrical protective shells 2 are moved and unfolded, thus opening the patient's vagina for easy examination by the doctor. At the same time, the connecting rod 44 drives the moving ring 41 to move, which in turn drives the rotating ring 51 to move, thereby causing the sampling rod 1 to extend out of the semi-cylindrical protective shell 2. Then, the adjusting rod 53 is used to swing the sampling rod 1 to adjust the angle of the sampling rod 1 for collecting vaginal discharge. This is simple and convenient. At the same time, the adjustment operation of the adjusting rod 53 avoids medical staff from touching the patient's body. Conversely, retracting the semi-cylindrical protective shell 2 moves the sampling rod 1 back into the semi-cylindrical protective shell 2, thereby preventing the sampling rod 1 from being contaminated by the outside world during the test and ensuring the accuracy of the test results.

[0045] Example 2

[0046] Please see Figures 3-7 The present invention provides a technical solution: a sampler for routine testing of vaginal discharge, including a sampling rod 1, which is composed of a hollow plastic tube and a cotton ball at the head, similar to a conventional cotton swab, and also includes a semi-cylindrical protective shell 2, which is provided with two pieces that fit together to form a hollow column 66 to wrap the sampling rod 1.

[0047] Drive component 3 is set on the semi-cylindrical protective shell 2. Drive component 3 drives the two semi-cylindrical protective shells 2 to move and open the patient's vagina.

[0048] Linkage component 4 is set inside two semi-cylindrical protective shells 2 and connected to the sampling rod 1. Moving the semi-cylindrical protective shell 2 and using the linkage component 4 to drive the sampling rod 1 to extend out of the semi-cylindrical protective shell 2 makes it convenient for medical staff to perform sampling operations.

[0049] Adjustment component 5 is installed inside two semi-cylindrical protective shells 2. Adjustment component 5 drives the sampling rod 1 to deflect for sampling. The semi-cylindrical protective shells 2 are then inserted into the patient's vagina. Drive component 3 moves and unfolds the two semi-cylindrical protective shells 2, thus opening the vagina. Simultaneously, linkage component 4 drives the sampling rod 1 to extend out of the semi-cylindrical protective shells 2. Adjustment component 5 then adjusts the angle of the sampling rod 1 to collect vaginal discharge. This process is simple and convenient. The adjustment rod 53 prevents medical staff from touching the patient's body. Conversely, retracting the semi-cylindrical protective shells 2 retracts the sampling rod 1 back into the shells, preventing contamination during sample collection and ensuring the accuracy of the test results.

[0050] The drive assembly 3 includes a hollow shaft 31 fixedly connected to one end of the semi-cylindrical protective shell 2. An arc plate 32 is rotatably connected to the hollow shaft 31 via a bearing. An arc plate 33 is rotatably connected to the hollow shaft 34 via a bearing. The arc plate 34 is fixedly connected to the arc plate 32. The arc plate 34 passes through the arc plate 33 and is rotatably connected to it via a bearing. Squeezing the arc plate 32 and the arc plate 33 causes the two semi-cylindrical protective shells 2 to move and open the patient's vagina.

[0051] A locking component 35 is provided on the first arc plate 32 and the second arc plate 33. The locking component 35 is used to limit and fix the first arc plate 32 and the second arc plate 33. So when the medical staff uses the semi-cylindrical protective shell 2 to open the patient's vagina, the locking component 35 can be used to lock the semi-cylindrical protective shell 2, thereby facilitating the operation of the medical staff.

[0052] One end of shaft 2 34 is fixedly connected to a limiting plate 36, and a torsion spring 37 is sleeved on shaft 2 34. The two ends of the torsion spring 37 are fixedly connected to the limiting plate 36 and the arc-shaped plate 2 33 respectively. Thus, in the initial state of the torsion spring 37, the two semi-cylindrical protective plates are in a closed state, thereby opening the two semi-cylindrical protective shells 2. At the same time, the torsion spring 37 is subjected to force and torsion to provide self-recovery capability for the two semi-cylindrical protective shells 2, which is simple and convenient.

[0053] The linkage component 4 includes a movable ring 41 disposed between two semi-cylindrical protective shells 2. The movable ring 41 is connected to the sampling rod 1, and two shafts 42 are symmetrically fixedly connected to the movable ring 41. Each of the two semi-cylindrical protective shells 2 is rotatably connected to a shaft 43 via bearings. A connecting rod 44 is disposed between the shaft 43 and one of the shafts 42. One end of the connecting rod 44 is fixedly connected to the shaft 43, and the other end is rotatably connected to the shaft 42 via bearings. Moving the semi-cylindrical protective shell 2 drives the connecting rod 44 to move, thereby driving the movable ring 41 to move, and in turn driving the sampling rod 1 to move.

[0054] The adjustment assembly 5 includes a rotating ring 51 disposed on one side of the moving ring 41. The rotating ring 51 is rotatably connected to the moving ring 41, and the moving ring 41 can drive the rotating ring 51 to move. A shaft 52 is rotatably connected inside the rotating ring 51 through a bearing. An adjustment rod 53 is fixedly connected to the shaft 52, and one end of the adjustment rod 53 is connected to the sampling rod 1. Moving the adjustment rod 53 causes the sampling rod 1 to deflect, thereby causing the sampling rod 1 to deflect for sampling, thereby increasing the sampling range.

[0055] Two shafts 54 are fixedly connected to the rotating ring 51, and each shaft 54 ​​is rotatably connected to an arc-shaped rod 55 via bearings. A guide rod 56 is fixedly connected inside the semi-cylindrical protective shell 2, and the guide rod 56 slides through one end of the arc-shaped rod 55 to guide the relative movement of the rotating ring 51. At the same time, the movement of the semi-cylindrical protective shell 2 drives the sampling rod 1 to rotate using the arc-shaped rod 55. Thus, when the sampling rod 1 is retrieved after collection, it can be driven to rotate synchronously, thereby driving it to rotate synchronously to wrap around the highly fluid leukorrhea, thus preventing the collected leukorrhea from dripping back into the vagina, causing a reduction in the sample volume, and thus improving the sampling effect.

[0056] The semi-cylindrical protective shell 2 has a placement groove 57, in which an elastic airbag 58 is fixedly connected. One end of the adjusting rod 53 is hollow, and the sampling rod 1 is also hollow with one end located inside the adjusting rod 53, so that the sampling rod 1 can be removed from the adjusting rod 53 and the main body of the device can be reused, thereby improving its practicality. A soft catheter 59 is conductively connected to one side of the elastic airbag 58, and one end of the soft catheter 59 passes through the semi-cylindrical protective shell 2 and is conductively connected to the adjusting rod 53. After being inserted into the semi-cylindrical protective shell 2, the patient's vagina is opened, and the elastic airbag 58 is squeezed to deform it. When the sampling rod 1 is retrieved after collection, the semi-cylindrical protective shell 2 is released, and the elastic airbag 58 returns to its original position, thereby sucking out the air in the sampling rod 1, thereby creating negative pressure at the end of the sampling rod 1, so that the vaginal discharge adheres tightly to the sampling rod 1, thereby further preventing the collected vaginal discharge from dripping back into the vagina, resulting in a reduction in the sample volume, and thus improving the sampling effect.

[0057] The locking assembly 35 includes an arc-shaped support plate 64 fixedly connected to one side of the arc-shaped plate 32. The arc-shaped support plate 64 has a plurality of slots 65 evenly spaced on it. A hollow column 66 is fixedly connected to the arc-shaped plate 33. A sliding pin 67 is slidably connected inside the hollow column 66.

[0058] A groove 68 is provided on the hollow column 66, and a rectangular protrusion 69 is fixedly connected to one end of the sliding pin 67. One end of the rectangular protrusion 69 slides through the groove 68, and a spring 71 is fixedly connected to one end of the sliding pin 67. One end of the spring 71 contacts and abuts against the inner wall of the hollow column 66. Moving the rectangular protrusion 69 causes the sliding pin 67 to be pulled out of the slot 65, and at the same time, the spring 71 is compressed to provide the sliding pin 67 with self-recovery capability.

[0059] One end of the sliding pin 67 is designed with a bevel, so that when the semi-cylindrical protective shell 2 is opened, the sliding pin 67 can automatically be inserted into the slot.

[0060] During the normal operation of the sampler used for routine vaginal discharge testing, the snap-fit ​​semi-cylindrical protective shell 2 is inserted into the patient's vagina. Then, by pinching the arc-shaped plate 32 and arc-shaped plate 33, the two semi-cylindrical protective shells 2 are moved and unfolded, thus opening the patient's vagina for easy examination by the doctor. At the same time, the connecting rod 44 drives the moving ring 41 to move, which in turn drives the rotating ring 51 to move, thereby causing the sampling rod 1 to extend out of the semi-cylindrical protective shell 2. Then, the adjusting rod 53 is used to swing the sampling rod 1 to adjust the angle of the sampling rod 1 for collecting vaginal discharge. This is simple and convenient. At the same time, the adjustment operation of the adjusting rod 53 avoids medical staff from touching the patient's body. Conversely, retracting the semi-cylindrical protective shell 2 moves the sampling rod 1 back into the semi-cylindrical protective shell 2, thereby preventing the sampling rod 1 from being contaminated by the outside world during the test and ensuring the accuracy of the test results.
