Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a vaginal sampling device. Background Technology

[0002] In the treatment of gynecological diseases, vaginal speculum is often used to open the vagina, facilitating examination and treatment. Existing vaginal speculum are typically designed in a duckbill shape, usually consisting of two blades resembling a duck's bill, hence the name "duckbill-shaped." The two blades are connected by a hinged structure. At one end of the connecting device, there is usually an adjustment mechanism, which may be a knob or a snap-on design, used to control the opening angle between the two blades.

[0003] During use, whether inserted or dilated, the duckbill-shaped edge of this type of vaginal speculum can easily scratch the vaginal wall.

[0004] When sampling is required, the patient's vagina needs to be opened at a significant angle. A sampling swab is then used through the gap between the two flaps to collect secretions from the vaginal wall. Therefore, for patients with small or delicate vaginas, such significant opening can more easily cause damage to the vaginal wall.

[0005] Therefore, there is an urgent need to develop a vaginal sampling device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a vaginal sampling device to solve the technical problem in the prior art where sampling is performed by using two leaf-shaped speculum to open the patient's vagina at a large angle, which easily leads to damage to the vaginal wall. The various technical effects of the preferred technical solution provided by this invention are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a vaginal sampling device, comprising:

[0009] A column for opening the patient's vagina, with a receiving cavity extending through the inside of the column and a sampling port communicating with the receiving cavity extending through the side wall of the column;

[0010] A clamping mechanism is used to clamp a cotton swab for collecting vaginal secretions. The clamping mechanism is slidably disposed inside the column. The cotton swab on the clamping mechanism slides to the sampling port to contact the patient's vaginal wall to collect secretions.

[0011] A sliding mechanism is installed between the clamping mechanism and the column to assist the clamping mechanism in moving within the receiving cavity.

[0012] Furthermore, the column is tapered, and during use, the diameter of the end of the column that preferentially contacts the patient's vagina is smaller than the diameter of the other end of the column.

[0013] Furthermore, the column is composed of two semi-cylinders combined together, including a fixed wing and a supporting wing. One end of the fixed wing and the supporting wing are connected by a hinge, and the other end is provided with a connecting mechanism for them to open or close together.

[0014] Furthermore, the connecting mechanism includes a frame, a push rod, and a support spring. The frame is sleeved on the end of the fixed wing and the support wing away from the hinge axis. The end of the fixed wing is fixedly connected to the inner wall of the frame. The support wing is movably disposed within the frame. The inner wall of the frame has a guide groove. The push rod is fixedly connected to the end of the support wing and slidably disposed within the guide groove. The support spring is disposed within the guide groove, with one end abutting against the bottom surface of the guide groove and the other end abutting against the push rod. The support spring is used to push the push rod to slide along the guide groove and drive the support wing to flip around the hinge axis to open the vagina.

[0015] Furthermore, one end of the push rod is fixedly connected to the side wall of the support wing, and the other end of the push rod protrudes from the frame for the user to press it so that the support wing fits against the fixed wing.

[0016] Furthermore, the clamping mechanism includes a support and two clamping columns. The support is connected to a sliding mechanism and is moved smoothly by the sliding mechanism. A through cavity is provided on the support, and the two clamping columns are slidably disposed in the through cavity and clamp the cotton swab by moving closer to each other. Two drive components for driving the two clamping columns to move closer to each other are installed on the support.

[0017] Furthermore, the drive assembly includes a drive shaft, a fixed shaft, and a drive spring. The support has a through hole along the sliding direction of the clamping column. One end of the drive shaft passes through the through hole and is fixedly connected to the side wall of the clamping column. The other end of the drive shaft has a receiving groove for accommodating the drive spring. One end of the fixed shaft is connected to the sliding mechanism, and the other end of the fixed shaft is inserted into the receiving groove and pressed against the drive spring. Under the action of the two drive assemblies, the two clamping columns are pushed closer together.

[0018] Furthermore, each of the two clamping posts is provided with a cylindrical groove for holding the cotton swab, and the two cylindrical grooves are connected to each other when the two clamping posts are spliced ​​together.

[0019] Furthermore, the sliding mechanism includes two sliders slidably disposed on the column, the column having two sliding grooves, the two sliders being slidably disposed within the sliding grooves and respectively fixedly connected to the clamping mechanism.

[0020] Furthermore, the two grooves are inclined along the length of the column, and the slider carrying the clamping mechanism moves gradually closer to or away from the sampling port along the slider.

[0021] This invention proposes a vaginal sampling device to address the problem in existing technologies that use two leaf-shaped speculum to open the patient's vagina at a large angle for sampling, which can easily lead to damage to the vaginal wall. The technical advantages of this device are reflected in the following aspects:

[0022] Reduced damage: Compared to traditional duckbill-shaped vaginal speculum, this invention uses a column to open the vagina, making it easier to fit into the patient's vagina, reducing the risk of stretching damage and avoiding the risk of scratching the vaginal wall with the edge. It can significantly reduce damage caused by a large opening angle, especially for patients with small or fragile vaginas.

[0023] Furthermore, the sampling port on the column facilitates the use of a clamping mechanism to hold the swab for sampling, thereby reducing the number of times the swab needs to be opened again and further reducing damage to the patient's vaginal wall.

[0024] Improved sampling efficiency and accuracy: The design of using a sliding mechanism to drive the clamping mechanism allows the swab to reach the required sampling location more accurately and to withdraw quickly after sampling, thus improving sampling efficiency and accuracy.

[0025] Improved ease of operation: The device of this utility model is simple and reasonable in design. Doctors can adjust the position of the cotton swab through the external control sliding mechanism during operation, which simplifies the operation steps and improves the user experience.

[0026] Increased patient comfort: Since it no longer relies on the opening and closing of the blades to expand the field of vision, the new column design provides a gentler expansion method, reducing patient discomfort.

[0027] In summary, this invention not only solves the problem of damage caused by traditional vaginal speculum, but also optimizes the sampling process, improving the ease of operation for doctors and the treatment experience for patients. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The following is in conjunction with the appendix Figure 1-3 To further illustrate this application, an embodiment of this application discloses a vaginal sampling device.

[0037] Reference Figure 1 and Figure 2 As shown, a vaginal sampling device includes a column 100, a clamping mechanism 200, and a sliding mechanism 300. The column 100 is composed of two semi-cylinders that are combined with each other. These two parts include a fixed wing 110 and a supporting wing 120, respectively. One end of the fixed wing 110 and the supporting wing 120 are fixedly connected by a hinge, while the other ends of the fixed wing 110 and the supporting wing 120 are separated from each other about the hinge axis.

[0038] The column 100 has an internal receiving cavity located on both the fixed wing 110 and the supporting wing 120. A sampling port 111 is also provided through the side wall of the column 100, directly communicating with the receiving cavity. A sliding mechanism 300 slides along the length of the column 100, allowing the clamping mechanism 200 mounted thereon to move with the sliding mechanism 300. The clamping mechanism 200 secures the swab or other sampling tool and, with the advancement of the sliding mechanism 300, allows the swab to contact the vaginal wall through the sampling port 111, thus achieving an efficient and painless secretion collection process.

[0039] The column 100 is designed as a tapered structure with a smaller diameter at the hinge end of the fixed wing 110 and the supporting wing 120, and a larger diameter at the end where they unfold towards each other. This design allows the smaller-diameter end of the column 100 to be inserted into the patient first, significantly reducing discomfort during insertion. As the insertion depth gradually increases, the diameter of the column 100 gradually expands, and by adjusting the unfolding angle between the fixed wing 110 and the supporting wing 120, the vaginal space is effectively widened, achieving the goal of ensuring ease of operation while minimizing impact on the patient's physiological structure.

[0040] The top of the column 100, i.e., the smaller diameter end of the column 100, is rounded to reduce the appearance of sharp edges, thereby further reducing harm to the patient when inserted into the patient's body. The other end of the column 100 is equipped with a connecting mechanism for the fixing wing 110 and the supporting wing 120 to open or close together.

[0041] Reference Figure 2 and Figure 3 As shown, the connecting mechanism includes a frame 410, a push rod 460, and a support spring 450. The frame 410 is fitted onto the large-diameter end of the column 100, meaning the frame 410 has a hollow interior with a receiving space 430. The frame 410 is fixedly connected to the outer wall of the fixed wing 110, while the support wing 120 is slidably opened and closed along the side wall of the frame 410. The frame 410 has two guide grooves 440 along the opening direction of the support wing 120, and the two guide grooves 440 are arranged opposite to each other. The push rod 460 has two parts that slide within the two guide grooves 440 respectively and are fixedly connected to the side walls of the two support wings 120. The push rod 460 can slide within the guide grooves 440 as the support wings 120 rotate, and it protrudes from the guide grooves 440, allowing medical personnel to adjust the position of the support wings 120 by directly moving the push rod 460.

[0042] Two support springs 450 are also provided, each located within one of the two guide grooves 440. One end of the support spring 450 abuts against the bottom surface of the guide groove 440, and the other end abuts against the side wall of the push rod 460. The function of the support springs 450 is to drive the push rod 460 to slide by applying elastic force, thereby causing the support wing 120 to rotate and open around the hinge axis.

[0043] During use, when the small-diameter end of the column 100 is inserted into the patient's body, pressing the push rod 460 compresses the support spring 450, causing the fixed wing 110 and the support wing 120 to come into contact with each other and reducing the opening angle of the column 100. This reduces the radial space required for insertion, effectively minimizing discomfort and potential damage to the patient. Once the predetermined insertion depth is reached, releasing the pressure on the push rod 460 causes the support spring 450 to automatically reset, prompting the support wing 120 to quickly flip to the open state, achieving effective support and exposure of the required area, improving operational convenience and patient comfort.

[0044] A handle 420 is also fixedly connected to the column 100. The handle 420 is fixedly connected to the side wall of the frame 410, so as to facilitate medical staff to hold it during use and to facilitate insertion into the patient's body.

[0045] Reference Figure 2 and Figure 3As shown, the clamping mechanism 200 includes a support 210 and two clamping posts 230. The support 210 is connected to the sliding mechanism 300, which allows the entire clamping mechanism 200 to smoothly move closer to or further away from the sampling port 111. A through cavity 220 is formed through the center of the support 210, and the two clamping posts 230 are slidably installed within this cavity 220, each with a semi-cylindrical design. When the two clamping posts 230 slide and fit together, they form a complete cylindrical structure.

[0046] Each clamping post 230 has a cylindrical groove. When two clamping posts 230 are fully engaged, the two cylindrical grooves form a complete slot for clamping the cotton swab. To achieve precise clamping of the cotton swab, the support 210 is also equipped with a drive assembly to drive the two clamping posts 230 to move closer together and clamp the cotton swab.

[0047] The drive assembly includes a drive shaft 250, a fixed shaft 280, and a drive spring 270. A through hole 240 is provided on the support 210 along the sliding direction of the clamping post 230. The drive assembly has two sets of holes, each corresponding to one of the two clamping posts 230. One end of the drive shaft 250 passes through the through hole 240 and is fixedly connected to the side wall of the clamping post 230. The other end of the drive shaft 250 has a receiving groove 260 for accommodating the drive spring 270. The drive shaft 250 can slide along the through hole 240 to move the clamping post 230.

[0048] One end of the fixed shaft 280 is slidably disposed within the receiving groove 260, and the other end of the fixed shaft 280 is fixedly connected to the sliding mechanism 300. The sliding mechanism 300, through the connection between the fixed shaft 280 and the drive shaft 250, carries the clamping column 230 and the support 210 to move. A drive spring 270 is disposed within the receiving groove 260, with one end abutting against the bottom surface of the receiving groove 260 and the other end abutting against the side wall of the fixed shaft 280. Utilizing the elastic force of the drive spring 270, the two clamping columns 230 can be effectively pushed closer together, achieving a reliable clamping function for the cotton swab.

[0049] Reference Figure 2 and Figure 3 As shown, the sliding mechanism 300 includes two sliders 320 slidably disposed on the column 100. The fixed wing 110 is provided with two sliding grooves 310. The two sliding grooves 310 are arranged opposite to each other and are inclined. That is, the sliding grooves 310 are inclined in a direction away from the large diameter end of the column 100 and the central axis of the column 100 is used as the reference line. The two sliders 320 are correspondingly slidably disposed in the two sliding grooves 310.

[0050] The fixed shaft 280 is fixedly connected to the slider 320, so that during the sliding process, the cotton swabs on the two clamping columns 230 are gradually brought closer to the sampling port 111 by the guide of the slide groove 310, thereby collecting secretions from the vaginal wall of the patient. Due to the inclined setting of the slide groove 310, when the clamping mechanism 200 is in the initial state, it is exactly in the middle position of the large diameter end of the column 100, which is convenient for medical staff to place the cotton swabs at this position. By manually pushing the sliding mechanism 300, the cotton swabs on the clamping mechanism 200 are gradually brought closer to the sampling port 111. This process does not require further widening of the opening angle, simplifies the sampling steps, improves the operation efficiency and patient comfort, and achieves a smooth transition of the cotton swab from the initial position to the sampling port 111.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
