Description

Technical Field

[0001] The present invention relates to the field of medical technology, and more particularly to an adjustable auxiliary device for gynecological and obstetric ultrasonic diagnosis. Background Art

[0002] In the field of obstetrics and gynecology clinical diagnosis, vaginal ultrasound testing, with its advantages of clear imaging and precise positioning, has become an important tool for early pregnancy monitoring and diagnosing gynecological diseases. However, the loss of coupling agent during the test seriously affects the quality and efficiency of the test. Vaginal ultrasound testing requires an even application of coupling agent to the probe to eliminate air between the probe and the vaginal mucosa and ensure effective transmission of ultrasound waves. However, in practice, the patient's vaginal muscles react involuntarily to probe stimulation, causing the coupling agent to be squeezed out and overflowed. This results in a loss of ultrasound transmission medium at the test site, blurring the image, artifacts, and other issues, seriously affecting the doctor's accurate assessment of key information such as embryonic development and lesion morphology. For example, in the diagnosis of early ectopic pregnancy, loss of coupling agent can obscure the subtle imaging features of tubal pregnancy, leading to missed or misdiagnosis. When monitoring fetal development, insufficient coupling agent can affect the accuracy of fetal diameter measurements.

[0003] In addition, the loss of coupling agent forces medical staff to frequently interrupt the test to reapply the coupling agent, which not only prolongs the test time and increases patient discomfort, but may also damage the original position of the probe due to the reapplying operation, reducing the continuity of the test. Existing solutions often adopt increasing the amount of coupling agent applied or using a more viscous coupling agent, but the former is prone to waste and may cause patient discomfort, while the latter has disadvantages such as residue that is difficult to clean and an increased risk of allergies. With the increasing demand for refined and efficient obstetric and gynecological ultrasound diagnosis, there is an urgent need to develop an auxiliary device that can effectively prevent the loss of coupling agent and optimize the detection process. This is the core research and development background and application value of this patented technology. In view of this, we propose an adjustable auxiliary device for obstetric and gynecological ultrasound diagnosis. Summary of the Invention

The interior of the handle is hollow, and the top of the handle is a concave portion, and the concave portion is provided with multiple drug inlets.

[0012] Preferably, the spiral guide body includes a straight body, one end of the straight body is fixed to the outer periphery of the wire-wrapped hose portion, and the other end of the straight body is connected to a ladder protrusion, the ladder protrusion is a trapezoidal structure, and a liquid flow channel is formed between the adjacent straight bodies and the inner periphery of the ladder protrusion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention utilizes a compression piece that deforms in response to human body temperature. When preheated and inserted into the vagina for testing, the body's body temperature causes the compression piece to deform, causing the inwardly convex section to squeeze the reservoir, causing the coupling agent to be automatically discharged from the outlet mesh of the discharge plate. This automatic replenishment of coupling agent avoids the need for medical staff to frequently interrupt testing for re-application, ensuring the continuity of the testing process, shortening testing time, and reducing patient discomfort. It also reduces the risk of probe position being disrupted by re-application operations, thus affecting test results. This solves the problem of coupling agent being easily squeezed out by muscle contraction, leading to inaccurate tests and misdiagnoses.

[0018] 2. The present invention also cleverly cooperates with the card and the card slot to dynamically adjust the amount of coupling agent replenished according to the degree of stimulation of the patient's vaginal muscles. When the sensitive part of the patient's vagina is stimulated, the card deforms and resets to achieve additional coupling agent replenishment, ensuring that sufficient coupling agent is maintained at different detection sites, avoiding problems such as blurred imaging due to lack of coupling agent, and stabilizing ultrasonic transmission, providing doctors with clear and accurate images and facilitating accurate diagnosis.

[0019] 3. The present invention also adopts a design combining a straight body and a stepped convex body through the spiral guide body of the coupling agent mechanism to form a unique liquid flow channel, using the viscosity of the coupling agent to guide excess coupling agent to flow downward. The protruding corners on both sides of the stepped convex are twisted and tightly attached to each other when the probe line is bent, effectively preventing the coupling agent from dripping at the bend and keeping the detection environment clean. At the same time, the protruding corners can also limit excessive bending of the line, protect the probe line, avoid signal loss due to line damage, and extend the service life of the probe.

[0020] 4. The present invention also achieves efficient collection of excess couplant through the coordinated operation of the handle and the pressure-suction mechanism. The doctor grasps the handle, presses the soft sleeve, and triggers the grip-control mechanism, which drives the curved handle clamp to squeeze the suction sleeve, expelling and collecting the couplant. After the spring resets the mechanism, the suction sleeve returns to its original position and can continue to absorb the couplant. This design avoids couplant accumulation, reduces the workload of post-test cleanup, improves the convenience of the test operation, and reduces the workload of medical staff.

[0021] 5. The present invention also realizes a convenient and efficient disinfection function by combining the inner plate layer, the outer plate layer and the expansion body of the drainage layer. When the device is immersed in the disinfectant, the expansion body made of the water-absorbing and expandable gel material reacts with the disinfectant and expands, pushing open the inner plate layer and connecting the inner groove and the outer groove, so that the disinfectant can fully enter the interior of the drainage layer for comprehensive and thorough disinfection, effectively removing the coupling agent residue, preventing bacterial growth, ensuring the hygiene and safety of the obstetrics and gynecology ultrasound diagnosis process, and providing patients with a more reliable medical environment.

[0038] like Figures 1 to 13 As shown, the present invention relates to an adjustable auxiliary device for obstetric and gynecological ultrasonic diagnosis, which is composed of a wrapped tube body as a whole, and the tube body is wrapped around the outer periphery of the vaginal probe used for gynecological ultrasonic diagnosis. The specific tube body includes an inner layer 101, and the inner layer 101 is made of a flexible material. The inner layer 101 is an adhesive layer and is bonded and fixed to the vaginal probe and part of the line connected to the vaginal probe. The inner layer 101 is wrapped with a probe hard tube part 102 near one end of the probe, and the probe hard tube part 102 cooperates with the vaginal probe. The other end of the inner layer 101 is wrapped with a wire-wrapped hose part 103, and the wire-wrapped hose part 103 is used to protect the line part. A plurality of agent storage capsules 2 are provided on the outer peripheral side wall of the probe hard tube part 102. The plurality of agent storage capsules 2 are distributed in a ring array. The agent storage capsules 2 are made of a soft material. A discharge layer plate 3 is installed on the opening side of the agent storage capsule 2, and a discharge mesh hole is opened on the discharge layer plate 3.

[0039] Compression sheets 4 are provided on both sides of the storage capsule 2. The compression sheets 4 are made of a material that is deformed by the human body temperature. The compression sheets 4 include bending sections 401 at both ends. The bending sections 401 are fixed to the probe hard tube portion 102. The bending sections 401 are in the shape of wavy wrinkles. An inward convex section 402 is provided between the two bending sections 401. The inward convex section 402 is an arc-shaped structure that bends toward the storage capsule 2. When the inward convex section 402 is deformed, it squeezes the side wall of the storage capsule 2. The wrinkled waves of the bending section 401 increase the movement amount of the inward convex section 402 by an inward deformation.

[0040] Working principle: Before use, in order to avoid cold stimulation, the device including the probe is immersed in warm water. After preheating is completed, during the preheating process, the compression piece 4 produces initial deformation preparation. During the inspection, the hard tube part 102 of the probe wrapped around the vaginal probe is inserted to inspect the interior. During the inspection, the human body temperature continuously provides temperature to the bent section 401 and the inward convex section 402 in the human body, which deforms. The bent section 401 is straightened, and the inward convex section 402 presses the storage capsule 2 inward and squeezes the coupling agent out from the discharge layer 3, thereby replenishing the coupling agent and avoiding frequent addition of coupling agent, which is beneficial to the inspection.

[0041] The above method can achieve automatic and uniform addition of coupling agent, but when the patient's vaginal muscles stimulate the more sensitive parts, it will produce stronger stimulation, which may easily lead to excessive loss of coupling agent.

[0042] The discharge layer plate 3 and the probe hard tube part 102 are limited and slide, and a gradual liquid discharge mechanism 5 is also provided at one end of the squeezing plate 4. The gradual liquid discharge mechanism 5 includes a spring card 501. The spring card 501 is elastic metal and is inserted into the discharge layer plate 3. The gradual liquid discharge mechanism 5 also includes a spring card slot 502 opened on the squeezing plate 4. The spring card 501 is a U-shaped structure. One end of the spring card 501 is inserted into the spring card slot 502. An extension section 403 is connected to the center of one side of the inner convex section 402. The extension section 403 is connected to the spring card 501. An empty slot is opened between the extension section 403 and the inner convex section 402. The empty slot is for crossing over part of the discharge layer plate 3 and providing a squeeze space. A plurality of protrusions 503 are connected to the side adjacent to the spring card slot 502 at the insertion end of the spring card 501, and the protrusions 503 on both sides are staggered.

[0043] Working principle: As mentioned above, when the inner convex section 402 is deformed, the extension section 403 also follows the deformation, causing the eject card 501 to move, and the multiple protrusions 503 on the cooperating eject card 501 and the protrusions 503 on the side wall of the eject card slot 502 are pressed against each other, gradually pressing the discharge agent layer 3 and resetting it, further realizing the gradual filling of coupling agent. At the same time, the elasticity of the eject card 501, when the sensitive part of the patient's vagina is greatly stimulated, will cause the eject card 501 to deform, and then reset after deformation. This process can be used to supplement additional coupling agent to avoid lack of coupling agent in the sensitive part, which affects the diagnosis result.

[0044] During probe diagnosis, excess coupling agent can easily contaminate the testing environment, and subsequent disinfection and cleaning are also more troublesome.

[0045] The probe hard tube portion 102 and the wire-wrapped hose portion 103 are provided with a fluid guiding mechanism 6, which includes a spiral guide body 601. The spiral guide body 601 is a spiral track distributed along the periphery of the wire-wrapped hose portion 103. The end of the spiral guide body 601 is provided with a handle 602 fixed to the wire-wrapped hose portion 103. The interior of the handle 602 is hollow, and the top of the handle 602 is a concave portion with multiple fluid inlets. The bottom of the handle 602 can be opened with a valve for discharging the collected coupling agent.

[0046] Working Principle: The design of the spiral guide 601 can guide excess coupling agent to flow away between the spiral guide 601 and outward. Combined with the design of the inner concave portion and the coupling agent inlet, the coupling agent can be concentrated and collected inside the handle 602.

[0047] Because the lines connecting the vaginal probe will bend frequently during diagnosis, relying solely on the spiral structure, the two sides of the spiral lack constraints after bending, and the gap is reduced, which makes it easy for the coupling agent to drip, affecting the detection environment, and further improvements are needed.

[0048] The spiral guide body 601 includes a straight body 6011, one end of the straight body 6011 is fixed to the outer periphery of the wire-wrapped hose portion 103, and the other end of the straight body 6011 is connected to a stepped protrusion 6012. The stepped protrusion 6012 has a trapezoidal structure, and a liquid flow channel is formed between the inner peripheries of adjacent straight bodies 6011 and stepped protrusions 6012. Protruding corners 6013 are integrally formed on both sides of the stepped protrusion 6012. An expansion line 6014 is provided inside the stepped protrusion 6012, and the expansion line 6014 is connected to multiple compression pieces 4. The expansion line 6014 is made of a material that expands under the influence of human body temperature.

[0049] Working Principle: Because the stepped protrusion 6012 is a trapezoidal structure with an enlarged diameter, it forms a fluid flow channel. Combined with the viscosity of the coupling agent, the coupling agent can flow within the fluid flow channel, achieving an excellent restraining effect. At the same time, when bending, the protruding corners 6013 on both sides of the stepped protrusion 6012 are intertwined and tightly attached to each other, further preventing the coupling agent from dripping at the bend.

[0050] It is worth mentioning that when bending, multiple protruding corners 6013 are close to each other and provide a certain degree of blocking, thereby preventing the bending from being too large and the line from being bent excessively, resulting in signal loss and damage due to long-term excessive bending.

[0051] If the coupling agent is only fed through the inlet, there may be residual liquid when there is a lot of coupling agent.

[0052] One end of the handle 602 is connected to a suction sleeve 603 near the inlet. The suction sleeve 603 is in a ring shape as a whole, and the cross-section of the suction sleeve 603 is a gourd-shaped structure. The gourd-shaped opening of the suction sleeve 603 passes through the handle 602. The suction sleeve 603 is made of medical repositionable rubber material. A drainage port is installed at the bottom of the suction sleeve 603, and a pressure suction mechanism 7 is provided on the periphery of the suction sleeve 603.

[0053] The pressure-suction mechanism 7 includes a central handle 701, one end of which is connected to a hinged head 702, and the hinged head 702 is hinged to two bent handle clamps 703. The bent handle clamp 703 is an angular structure, and one end of the bent handle clamp 703 is located in the middle section of the suction sleeve 603 gourd. The side of the bent handle clamp 703 is attached with an extrusion slope block 704 connected to the handle 602.

[0054] The central area of ​​the handle 602 is an elastic soft cover 604, and a gripping mechanism 8 is provided on the inner side of the soft cover 604. The gripping mechanism 8 includes a wave-section column 801 fixed to the central handle 701. The wave-section column 801 is a multi-section wave-shaped structure. A spring 802 is bonded between one end of the wave-section column 801 and the inner wall of the handle 602. The spring 802 plays the role of positioning and elastic reset. A convex pressure head 803 connected to the soft cover 604 is provided on one side of the wave-section column 801, and the convex pressure head 803 is made of hard material.

[0055] Working principle: When in use, the handle 602 is convenient for the doctor to hold. When the coupling agent accumulates a lot, the palm of the hand presses the soft sleeve 604, driving the convex pressure head 803 to squeeze the wave section column 801, causing the wave section column 801 to move. When moving, it drives the central handle 701 to move, pulling the two curved handle clamps 703 to displace. In the first half of the displacement, the slope of the extrusion slope block 704 guides the ends of the two curved handle clamps 703 to be clamped to the middle section of the suction sleeve 603 to prevent the coupling agent from being discharged outward. In the second half of the displacement, the lower half of the suction sleeve 603 is squeezed to discharge the internal coupling agent. The elastic force of the spring 802 restores the curved handle clamps 703 to their original position, and further restores the suction sleeve 603 to its original state, which can also absorb the coupling agent, further improve the collection efficiency of the coupling agent and prevent the occurrence of fluid accumulation.

[0056] Due to the presence of the drainage layer 3, it is not convenient to perform disinfection and cleaning.

[0057] The discharge layer plate 3 includes an inner plate layer 301, the outer periphery of the inner plate layer 301 is fixed to the inner wall of the opening of the storage bag 2, the inner plate layer 301 is elastic rubber, and the outer plate layer 302 is attached to one side of the inner plate layer 301, the inner plate layer 301 is equipped with multiple discharge heads 303 and has an inner through groove 304, and the outer plate layer 302 has multiple outer through grooves 305 corresponding to the discharge heads 303. An expansion body 306 that expands when in contact with the disinfectant is bonded between the inner plate layer 301 and the outer plate layer 302. The expansion body 306 is a water-absorbing and expandable gel material. It should be noted that the water-absorbing and expandable gel material will only react with the disinfectant, but will not react with the coupling agent and human body fluids.

[0058] Water-swellable gel materials are typically composed of specific polymers with specialized chemical groups embedded in their molecular chains. For example, they may contain functional groups with a high affinity for certain ions (such as hypochlorite ions, commonly found in chlorine-containing disinfectants) or chemical components (such as the hydroxyl groups in ethanol) in disinfectants. These functional groups can chemically react or physically adsorb with the corresponding components in the disinfectant. For example, in chlorine-containing disinfectants, certain electrophilic groups in the gel material may undergo nucleophilic substitution or redox reactions with hypochlorite ions, triggering changes in the internal chemical environment of the gel material, causing it to absorb water and expand, which then returns to its original size upon drying.

[0059] Working principle: When cleaning is required, immerse it in disinfectant, the expansion body 306 expands with the water, pushes open the inner plate layer 301, and increases the gap between the inner plate layer 301 and the outer plate layer 302, so that the outer groove 305 is connected with the inner groove 304, which facilitates the entry of disinfectant and makes disinfection more thorough.

[0060] In order to facilitate the addition of liquid, a liquid filling cover is installed on the discharge layer plate 3. By opening the cover, the coupling agent can be easily filled into the interior.

[0061] The extrusion sheet 4 and the expansion wire 6014 can be made of shape memory polymer or shape memory alloy, such as polylactic acid (PLA)-based SMP, titanium-based shape memory alloy, nickel titanium (NiTi)-based shape memory alloy, etc.

[0062] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
