Description

Technical Field

[0001] The present invention relates to the technical field of dilators for drugs, and particularly relates to a combined vaginal speculum. Background Art

[0002] During vaginal examinations, vaginal dilators are commonly used medical devices for dilating the vagina to enable observation of the internal vagina. Currently, traditional duckbill-shaped vaginal dilators have exposed many problems in actual clinical applications, causing obvious discomfort to patients, which are specifically reflected in the following aspects:

[0003] The vagina itself has a relatively narrow width, while the width of traditional duckbill-shaped dilators is relatively large, which makes it difficult to insert the dilator into the vagina. During the insertion process, it is extremely easy to cause a large degree of extrusion to the vagina, thereby causing pain to the patient. To alleviate this problem, the current operating specifications require the dilator to be inserted into the vagina at an angle of 45° in the closed state to reduce extrusion. However, this operation method is not only more cumbersome, increasing the operation difficulty and time cost of medical staff, but also in actual operation, there are cases where medical staff forget to insert it at an angle due to negligence, resulting in unnecessary pain for the patient.

[0004] Most existing traditional vaginal dilators adopt a scissor-like opening method. Under this structure, when the upper and lower dilator blades are opened, the opening degree of the hinge end is small, while the opening degree of the free end is large, resulting in inconsistent opening degrees during the dilation process of the dilator. This difference in opening degrees makes the extrusion of the free end on the vagina more significant, with the pressure concentrated on the free end part, further exacerbating the discomfort of the patient and posing a risk of damage to the vaginal tissue.

[0005] Traditional duckbill-shaped dilators mainly observe the internal situation of the vagina through the gaps formed on both sides after the two blades are opened. When it is necessary to comprehensively observe the upper and lower sides of the vagina, the dilator has to be rotated. However, due to the flat duckbill-shaped blade design of the dilator, friction and extrusion will occur again with the vaginal tissue during the rotation process, thus causing discomfort to the patient again and also possibly affecting the accuracy and efficiency of the observation. Summary of the Invention

[0006] The present invention aims to provide a combined vaginal speculum to solve the problem of strong discomfort during the use of existing duckbill-shaped dilators.

[0007] To achieve the above objective, the present invention adopts the following technical solutions:

[0008] A combined vaginal speculum, comprising a semi-circular upper dilating blade and a semi-circular lower dilating blade. A fixed handle is connected to the tail of the lower dilating blade, and a movable handle is connected to the tail of the upper dilating blade. The movable handle is slidably connected to the fixed handle. The upper dilating blade and the lower dilating blade are arranged in parallel. By sliding the movable handle on the fixed handle, the upper dilating blade and the lower dilating blade can be driven to open and close in parallel. The movable handle is also connected with a locking mechanism for fixing the movable handle. Water-soluble film sacs are fixed on the surfaces of the heads of the upper dilating blade and the lower dilating blade, and lubricants are coated in the water-soluble film sacs.

[0009] Preferably, as an improvement, the locking mechanism includes a screw. Vertical sliding holes are formed in the fixed handle and the movable handle, and the sliding holes in the fixed handle and the movable handle are aligned. The screw is slidably inserted through the two sliding holes. A limiting block is fixedly connected to one end of the screw, and a locking nut is threadedly connected to the other end of the screw.

[0010] Preferably, as an improvement, sampling bristles are arranged on the end faces of the heads of the upper dilating blade and the lower dilating blade.

[0011] Preferably, as an improvement, a thin medicine tube is arranged inside the upper dilating blade. One end of the thin medicine tube is located at the sampling bristles, and the other end of the thin medicine tube extends outside the movable handle.

[0012] Preferably, as an improvement, an elastic thin diaphragm is coated outside the sampling bristles. The edge of the elastic thin diaphragm is fixed on the edges of the upper dilating blade and the lower dilating blade. The elastic wave diaphragm is coated outside the sampling bristles in a stretched state. An easy-to-tear line is arranged in the middle of the elastic wave diaphragm. When the upper dilating blade and the lower dilating blade are separated, the elastic wave diaphragm can be separated from the easy-to-tear line.

[0013] Preferably, as an improvement, it further includes a cover shell for covering the heads of the upper dilating blade and the lower dilating blade when the upper dilating blade and the lower dilating blade are closed. A rubber pad is arranged on the inner wall of the cover shell.

[0014] The principle and beneficial effects of this solution are as follows:

[0015] 1. This solution realizes vaginal dilation through the parallel opening and closing of the upper dilating blade and the lower dilating blade. Before entering the vagina, the upper dilating blade and the lower dilating blade are in a closed state. After entering the vagina, the medical staff push the movable handle upward. The movable handle slides on the fixed handle, driving the upper dilating blade away from the lower dilating blade, thereby dilating the vagina. Compared with the scissor-type opening and closing method of the traditional duckbill dilator, this parallel opening and closing method makes the upper dilating blade and the lower dilating blade separate horizontally, with the same opening degree of each part and balanced force, avoiding the problem of concentrated internal pressure caused by the large internal opening degree and relatively small external opening degree of the traditional dilator, and greatly reducing the discomfort of the patient during the examination.

[0016] 2. The designed width of the semi-circular blade is smaller than that of the existing duckbill dilator, making it easier to enter the vagina. There is no need to enter at an inclination of 45° according to the traditional operation specifications, which simplifies the operation process, reduces the operation difficulty of medical staff, and also reduces the pain brought to patients due to improper operation.

[0017] 3. The semi-circular blades are used, and the whole is circular after being buckled. During the clinical examination, when medical staff need to horizontally rotate the checker to adjust the observation position, the circular shape can better adapt to the physiological structure inside the vagina. Compared with the traditional flat duckbill dilator, the circular structure has a more uniform contact with the vaginal wall during rotation, and the friction force distribution is also more balanced, without the situation of excessive local force. This makes the rotation process of the checker smoother, avoiding scratching or squeezing the patient's vaginal wall due to rotation, and thus not bringing new discomfort to the patient, significantly improving the comfort of the patient during the examination.

[0018] 4. When the upper dilating blade and the lower dilating blade enter the vagina, the water-soluble film sac at the head will rupture due to contact with the moist environment in the vagina and being subjected to a certain amount of extrusion. After the water-soluble film sac ruptures, the lubricant encapsulated inside will leak out and be evenly coated on the surfaces of the upper dilating blade and the lower dilating blade as the upper dilating blade and the lower dilating blade enter. This design not only provides good lubrication for the upper dilating blade and the lower dilating blade to enter the vagina, reduces the friction between the upper dilating blade and the lower dilating blade and the vaginal wall, makes the checker more convenient to enter the vagina, and further alleviates the discomfort of the patient. Moreover, the water-soluble film sac is set at the heads of the upper dilating blade and the lower dilating blade. When the upper dilating blade and the lower dilating blade contact the vagina, the water-soluble film sac contacts the vagina first. Compared with the direct hard contact of the upper dilating blade and the lower dilating blade, it can play a buffering role and reduce the initial discomfort of the patient.

[0019] 5. The locking mechanism consists of a screw, a limit block and a locking nut. Vertical and aligned sliding holes are opened on the fixed handle and the movable handle. The screw slides through the two sliding holes, with a limit block fixed at one end and a locking nut connected by threads at the other end. After the movable handle pushes the upper dilating blade to dilate the vagina to a proper position, the locking nut is tightened to fix the movable handle. The structure is simple, the operation is convenient, and the locking is stable, which can effectively prevent the dilating blade from accidentally moving during the examination and ensure the stability and safety of the examination process.

[0020] 6. Sampling bristles are provided on the end faces of the upper expansion blade head and the lower expansion blade head. When vaginal tissue or secretions need to be sampled, medical staff can rotate the checker to collect samples through the bristles. This design integrates the sampling function into the vaginal checker, avoiding the replacement of instruments during the examination, reducing the operation steps, improving the examination efficiency, and at the same time reducing the discomfort caused to patients by multiple operations.

[0021] 7. A thin medicating tube is provided inside the upper expansion blade. One end of the thin medicating tube is located at the sampling bristles, and the other end extends outside the movable handle. When vaginal medication treatment is required, medical staff can inject the liquid medicine through the thin medicating tube to the bristles, and then use the bristles to evenly coat the liquid medicine on the inner wall of the vagina. This design realizes the integration of examination and treatment, facilitating medical staff to timely treat patients during the examination, and improving the timeliness and effectiveness of treatment.

[0022] 8. The sampling bristles are covered with an elastic thin diaphragm. The edge of the elastic thin diaphragm is fixed on the edges of the upper expansion blade and the lower expansion blade, covering the sampling bristles in a stretched state. An easy-to-tear line is provided in the middle. During the process of the checker entering the vagina, the elastic thin diaphragm can block the sampling bristles and the thin medicating tube, avoiding discomfort caused by the bristles contacting the inner wall of the vagina, and at the same time preventing lubricating oil from entering the medicating channel and affecting the medicating effect. When the upper expansion blade and the lower expansion blade are opened, the relatively large opening force will cause the elastic thin diaphragm to separate into upper and lower pieces from the easy-to-tear line. At this time, the bristles and the medicating channel are exposed, and normal sampling and medicating operations can be carried out. The separated two pieces of elastic thin diaphragm will be rolled up to the edges of the upper expansion blade and the lower expansion blade due to their own elasticity, and will not block the sampling operation of the bristles.

[0023] 9. The checker further includes a cover shell. When leaving the factory and being packaged, the cover shell is used to cover the heads of the upper expansion blade and the lower expansion blade when they are closed. The cover shell has two main functions. One is a water-soluble film capsule to prevent it from being damaged during transportation and storage; the other is to lock the upper expansion blade and the lower expansion blade to prevent the two blades from being accidentally opened when not in use, such as the locking nut becoming loose due to the jolting during transportation and causing the blades to be accidentally opened. A rubber pad is provided on the inner wall of the cover shell. On the one hand, the rubber pad has flexibility and can further protect the water-soluble film capsule; on the other hand, when the rubber pad contacts the blade, it increases the friction force, ensuring the stability of the cover shell on the blade, and at the same time avoiding scratching the blade surface when the cover shell contacts the blade.

[0030] Figure 7 This is a schematic structural diagram of Embodiment 5 of the present invention. Detailed implementation manners

[0031] The following is a further detailed description through specific implementation manners:

[0032] The reference numerals in the accompanying drawings of the specification include: upper expansion blade 1, lower expansion blade 2, fixed handle 3, movable handle 4, sliding hole 5, screw rod 51, locking nut 52, water-soluble film capsule 6, sampling brush bristles 7, medicine application thin tube 8, elastic thin diaphragm 9, easy-to-tear line 91, and cover 10.

[0033] Embodiment 1:

[0034] As Figure 1 and Figure 2 shown, a combined vaginal speculum includes an upper expansion blade 1 with a semi-circular cross-section and a lower expansion blade 2 with a semi-circular cross-section. The expansion blade and the lower expansion blade 2 are arranged in parallel. A fixed handle 3 is integrally formed at the tail of the lower expansion blade 2, and a movable handle 4 is integrally formed at the tail of the upper expansion blade 1. The movable handle 4 overlaps with the fixed handle 3 and the movable handle 4 is slidably connected to the fixed handle 3. Specifically, vertical dovetail grooves (not shown in the figure) are opened on both sides of the front surface of the fixed handle 3, and two dovetail blocks (not shown in the figure) are integrally formed on both sides of the back surface of the movable handle 4. The two dovetail blocks are respectively slidably connected in the two dovetail grooves, thereby enabling the movable handle 4 to be slidably connected to the fixed handle 3. By sliding the movable handle 4 up and down on the fixed handle 3, the upper expansion blade 1 and the lower expansion blade 2 can be driven to open and close in parallel.

[0035] The movable handle 4 is also connected with a locking mechanism for fixing the movable handle 4. The locking mechanism includes a screw rod 51. Vertical sliding holes 5 are formed in the middle parts of the fixed handle 3 and the movable handle 4, and the sliding holes 5 on the fixed handle 3 and the movable handle 4 are aligned. The screw rod 51 slidably penetrates through the two sliding holes 5. One end of the screw rod 51 located on the back surface of the fixed handle 3 is adhesively fixedly connected with a limit block (not shown in the figure). The size of the limit block is larger than the width of the sliding hole 5 and is used to abut against the back surface of the fixed handle 3. The front end of the screw rod 51 is threadedly connected with a locking nut 52. When the locking nut 52 is loosened, the movable handle 4 can slide, and when the locking nut 52 is tightened, the movable handle 4 can be fixed.

[0036] Water-soluble film capsules 6 are adhesively fixed on the head surfaces of the upper expansion blade 1 and the lower expansion blade 2. Lubricants are coated inside the water-soluble film capsules 6, and glycerol is used as the lubricant.

[0037] In this embodiment, the whole checker is made of the transparent material used in the existing disposable vaginal speculum, such as medical-grade polystyrene (PS), polypropylene (PP), and polycarbonate (PC).

[0038] A using method of a combined vaginal checker:

[0039] In actual use, the patient takes the lithotomy position. The medical staff holds the checker and slowly inserts the upper expansion blade 1 and the lower expansion blade 2 in the closed state into the vagina. Since the width of the semi-circular blade is small, it can enter the vagina more easily without tilting at 45°, reducing the operation difficulty and at the same time reducing the stimulation to the patient. During the insertion process, the water-soluble film capsules 6 at the heads of the upper expansion blade 1 and the lower expansion blade 2 come into contact with the moist environment in the vagina and are squeezed by the vagina. The water-soluble film capsules 6 rupture, and the lubricants inside flow out and are evenly coated on the surfaces of the upper expansion blade 1 and the lower expansion blade 2 as the upper expansion blade 1 and the lower expansion blade 2 enter the vagina, lubricating the upper expansion blade 1 and the lower expansion blade 2 and further reducing the discomfort during insertion.

[0040] When the checker is inserted to an appropriate depth, the medical staff pushes the movable handle 4 upward. The movable handle 4 slides on the fixed handle 3, driving the upper expansion blade 1 away from the lower expansion blade 2 to realize the parallel expansion of the vagina. After expanding to an appropriate opening, the locking nut 52 is tightened to fix the movable handle 4 to ensure that the blades will not move during the inspection process.

[0041] The medical staff observes the internal situation of the vagina through the gap between the upper expansion blade 1 and the lower expansion blade 2, or can also observe through the transparent upper expansion blade 1 and lower expansion blade 2. If the observation angle needs to be adjusted, the checker can be rotated horizontally. Since the semi-circular blades are circular after being buckled, the contact with the vaginal wall is more uniform during the rotation process, the rotation is smoother, and no new discomfort will be brought to the patient.

[0042] Example 2:

[0043] Combined with Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that sampling bristles 7 are adhesively fixed on the end faces of the heads of the upper expansion blade 1 and the lower expansion blade 2. The sampling bristles 7 are made of a material with moderate hardness to avoid damaging the vagina while completing sampling. For example, polyester fiber material can be used to make the sampling bristles 7 with moderate hardness.

[0044] Using this embodiment, if sampling is required, medical staff can rotate the checker and use the sampling bristles 7 to collect samples of vaginal tissue or secretions.

[0045] Example 3:

[0046] Combined with Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that a medicine application thin tube 8 is embedded in the upper expansion blade 1. One end of the medicine application thin tube 8 is located at the sampling bristles 7, and the other end of the medicine application thin tube 8 extends outside the movable handle 4. The medicine application thin tube 8 in the figure is only for illustration, and in actual use, it can be set to an appropriate diameter according to needs.

[0047] Using this embodiment, if the patient needs medicine application treatment, medical staff can inject the liquid medicine through the medicine application thin tube 8 to the sampling bristles 7, and then use the sampling bristles 7 to evenly coat the liquid medicine on the inner wall of the vagina, realizing the simultaneous progress of examination and treatment.

[0048] Example 4:

[0049] Combined with Figure 5 and Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the sampling bristles 7 are coated with an elastic thin diaphragm 9. The elastic thin diaphragm 9 is coated outside the sampling bristles 7 in a stretched state. The edge of the elastic thin diaphragm 9 is adhesively fixed on the edges of the upper expansion blade 1 and the lower expansion blade 2 in the closed state. An easy tear line 91 is provided in the middle of the elastic thin diaphragm 9. When the upper expansion blade 1 and the lower expansion blade 2 are separated, the elastic wave diaphragm can be separated from the easy tear line 91. The elastic thin diaphragm 9 is made of natural rubber or silicone rubber.

[0050] In this embodiment, during the process of the checker entering the vagina, the elastic thin diaphragm 9 can block the sampling brush bristles 7 and the medicine application capillary tube 8, avoiding discomfort caused by the bristles contacting the inner wall of the vagina. At the same time, it prevents lubricating oil from entering the medicine application channel and avoids affecting the medicine application effect. After the checker enters the vagina, when separating the upper expansion blade 1 and the lower expansion blade 2, the relatively large pulling force when the upper expansion blade 1 and the lower expansion blade 2 are separated tears the elastic thin diaphragm 9 into upper and lower pieces from the tear line 91, thereby exposing the sampling brush bristles 7 and the medicine application capillary tube 8, enabling them to be used normally. The two separated elastic thin diaphragms 9 will be wound to the edges of the upper expansion blade 1 and the lower expansion blade 2 due to their own elasticity and will not block the sampling operation of the brush bristles.

[0051] Embodiment 5:

[0052] Combined with Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that it further includes a cover 10. The cover 10 is used to cover the heads of the upper expansion blade 1 and the lower expansion blade 2 when the upper expansion blade 1 and the lower expansion blade 2 are closed. A layer of rubber pad is adhesively fixed on the inner wall of the cover 10.

[0053] In this embodiment, when the checker leaves the factory, the upper expansion blade 1 and the lower expansion blade 2 are in a closed state, and the heads of the upper expansion blade 1 and the lower expansion blade 2 are covered with the cover 10. The water-soluble film capsule 6 can be protected by the cover 10. In addition, the rubber pad provided on the inner wall of the cover 10 can enhance the protection of the water-soluble film capsule 6, and at the same time increase the friction between the cover 10 and the blade to prevent the cover 10 from falling off.

[0054] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
