Description

Technical Field

[0001] This application relates to the field of storage sleeve technology, and more particularly to a storage sleeve that can temporarily store coupling agent. Background Technology

[0002] Ophthalmic ultrasound is a method of eye examination that uses ultrasound waves. It transmits high-frequency sound waves to the eyeball and eye tissues, measures the time and intensity of the reflected sound waves, and thus generates an image of the internal structure of the eyeball. Coupling agent is a substance used to enhance energy transfer between two media, and is commonly used in ultrasound examinations or industrial testing. A storage sleeve for temporarily storing coupling agent is an auxiliary device used in ophthalmic ultrasound examinations. It is usually made of special materials and can effectively store the coupling agent.

[0003] Currently, a Chinese utility model patent application with a publication date of December 31, 2021, and publication number CN 215349080U, discloses an ophthalmic B-mode ultrasound device, including an ultrasound probe. The front end of the ultrasound probe is covered with a coupling agent storage sleeve made of silicone. The coupling agent storage sleeve includes a fixing sleeve that is fitted onto the outer wall of the front end of the ultrasound probe. The front end of the fixing sleeve has a bowl-shaped storage bowl with the opening of the storage bowl facing the surface of the eyeball. The front end of the ultrasound probe passes through the storage bowl and is located at the bottom of the storage bowl. It has the advantages of effectively storing coupling agent and ensuring that there is still enough coupling agent around the ultrasound probe when changing the examination position in three modes: axial scanning, longitudinal scanning, and transverse scanning.

[0004] In one type of ophthalmic ultrasound device, the coupling agent storage sleeve may leak out during use due to excessive probe movement or prolonged examination time. Since the coupling agent cannot be replenished promptly, air gaps will form between the probe and the skin, causing significant reflection of ultrasound waves during propagation. This results in a marked decrease in image quality, affecting the doctor's accurate assessment of eye structures and lesions.

[0005] Therefore, it is necessary to provide a storage sleeve that can temporarily store the coupling agent to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] In the coupling agent storage sleeve of an ophthalmic B-ultrasound device in the related art, the coupling agent in the storage bowl may be lost due to frequent movement of the probe during examination or long examination time, but the coupling agent cannot be supplemented in time. If the coupling agent is lost, an air gap will appear between the probe and the skin, a large amount of reflection will occur in the propagation of ultrasonic waves, the image quality will obviously decrease, and the accurate judgment of the doctor on the eye structure and the lesion will be affected.

[0031] Based on this, in order to improve the technical problems that the coupling agent may be lost during the inspection process, the coupling agent cannot be supplemented in time, a large amount of reflection occurs in the propagation process of the ultrasonic wave, and the image quality is reduced in the related art, the embodiments of the present application provide the following solutions.

[0032] For reference Figs. 1 to 3 The embodiments of the present application provide a storage sleeve capable of temporarily storing coupling agent, which comprises a B-ultrasound probe 1, a coupling agent storage sleeve 2, a piston air bag member 3 and a storage bowl 23. The B-ultrasound probe 1 is used for inspecting the eye of a person. The coupling agent storage sleeve 2 is movably arranged on the B-ultrasound probe 1 through a fixing sleeve opening 21 formed on the coupling agent storage sleeve 2. The coupling agent storage sleeve 2 is provided with a storage cavity 22 for storing coupling agent. The piston air bag member 3 is arranged on the coupling agent storage sleeve 2 through the storage cavity 22 and is used for extruding the coupling agent in the storage cavity 22. The storage bowl 23 is arranged on the coupling agent storage sleeve 2. A connecting cavity 232 is formed in the side wall of the storage bowl 23 and is in communication with the storage cavity 22. An accommodating cavity 233 is formed in the inner wall of the storage bowl 23 and is in communication with the fixing sleeve opening 21, so as to facilitate the adhesion of the coupling agent to the eye and to eliminate the air between the probe and the skin.

[0033] The storage sleeve capable of temporarily storing coupling agent provided by the embodiments of the present application is used. Before the user uses the B-ultrasound probe 1 to inspect the eye of a patient, the user injects coupling agent into the storage cavity 22 through the outside. The coupling agent is gathered in the storage cavity 22 and the connecting cavity 232. The coupling agent enters the accommodating cavity 233 in the inner wall of the storage bowl 23 through the connecting cavity 232. During use, if the coupling agent is lost and needs to be supplemented, the volume of the storage cavity 22 can be directly extruded by the piston air bag member 3, so that the coupling agent in the storage cavity 22 is extruded into the accommodating cavity 233 for supplement. In this way, the coupling agent can be supplemented by extruding the volume of the storage cavity 22 by the piston air bag member 3, so as to ensure the sufficiency of the coupling agent and avoid the increase of image blur or artifacts caused by insufficient coupling agent, thereby improving the accuracy and reliability of the inspection.

[0034] In some embodiments, the piston air bag member 3 comprises a gas storage pipe 32 arranged on the coupling agent storage sleeve 2. An air guide cavity 321 is formed in the inner wall of the gas storage pipe 32. An air vent hole 34 is formed in the gas storage pipe 32 and is in communication with the air guide cavity 321. A telescopic air bag 31 is arranged in the coupling agent storage sleeve 2 and is in communication with the telescopic air bag 31. A piston rod 33 is slidably and sealingly arranged in the gas storage pipe 32 and is used for extruding the gas in the gas storage pipe 32.

[0035] In this way, during use, if the coupling agent is lost and needs to be supplemented, the coupling agent can be directly supplemented by pressing the piston rod 33. The piston rod 33 pushes the gas in the gas guide cavity 321 in the gas storage tube 32, and the gas in the gas guide cavity 321 is compressed through the air hole 34 to the telescopic air bag 31. The telescopic air bag 31 expands to squeeze the coupling agent in the storage cavity, so as to squeeze the coupling agent in the storage cavity 22 into the containing cavity 233 in the storage bowl 23 for supplement. In this way, the supplement operation of the coupling agent can be completed directly by pressing the piston rod 33, without the need for complex disassembly or additional tools, greatly simplifying the supplement process, saving operation time and effort. Since the coupling agent is directly squeezed from the internal storage cavity into the containing cavity 233 of the storage bowl 23, the entire process is in a relatively closed system, avoiding excessive contact with the external environment, thereby effectively reducing the possibility of contamination of the coupling agent. The mechanical transmission and pneumatic principle of the coupling agent supplement realized by the piston rod 33, the gas guide cavity 321, and the telescopic air bag 31 is relatively simple, and the cooperation between the various components is relatively stable and reliable, and is not prone to failure.

[0036] In some embodiments, the coupling agent storage sleeve 2 is also provided with a guide-in member 4, which includes a one-way valve 42 arranged on the coupling agent storage sleeve 2 to facilitate injection of the coupling agent into the storage cavity 22 without flowing out, and a guide-in pipe 41 arranged on the one-way valve 42 for guiding the coupling agent.

[0037] In this way, the user injects the coupling agent into the storage cavity 22 through the guide-in pipe 41 and the one-way valve 42 before using the B-ultrasound probe 1 to examine the patient's eye. In this way, the advance injection of the coupling agent through the guide-in pipe 41 and the one-way valve 42 can ensure that there is enough amount of coupling agent in the storage cavity 22, avoiding interruption of the operation due to insufficient coupling agent during the examination, affecting efficiency and experience. The one-way valve 42 can prevent the coupling agent in the storage cavity 22 from flowing back and prevent bacteria and other pollutants from entering, keeping it clean. In eye examination, the risk of eye infection can be reduced to ensure patient safety.

[0038] In some embodiments, the storage bowl 23 is internally provided with an array of through holes 24 for uniform extrusion of the coupling agent.

[0039] In this way, the storage bowl 23 is internally provided with an array of through holes 24 for uniform extrusion of the coupling agent. In this way, the array of through holes 24 can uniformly extrude the coupling agent from the storage cavity 22 and cover the probe surface, which can effectively reduce the air gap between the probe and the eye, make the ultrasonic wave propagate more smoothly between the probe and the eye, enhance the transmission efficiency of the ultrasonic signal, improve the clarity and resolution of the ultrasonic image, and help the doctor more accurately observe the eye structure and lesions.

[0040] In some embodiments, the B-ultrasound probe 1 is provided with a mark point 11, and the coupling agent storage sleeve 2 is provided with a mark window 25 for displaying the mark point 11 of the B-ultrasound probe 1.

[0041] In this way, the mark window 25 is used to determine the direction of the mark point 11 of the B-ultrasound probe 1 when the coupling agent storage sleeve 2 is sleeved on the B-ultrasound probe, and can also be used to control the axial position of the fixed sleeve when the fixed sleeve is sleeved on the B-ultrasound probe 1, so as to avoid the B-ultrasound probe 1 from being too deep. In this way, in ophthalmic examination, the doctor needs to accurately understand the position of the probe in order to make accurate diagnosis, and the mark window 25 can help the doctor quickly determine the direction of the mark point 11 of the B-ultrasound probe 1, so as to better judge the specific position and angle of the probe in the eye.

[0042] In some embodiments, the storage bowl 23 is provided with a connecting edge 231 at the bowl opening, and the connecting edge 231 is in a wave shape.

[0043] In this way, the connecting edge 231 is used to improve the fit with the surface of the eyeball and can reduce discomfort, and the wave-shaped connecting edge 231 ensures its softness, which can provide more variable volume for the inner cavity of the storage bowl 23 when fitting, so as to control the degree of fit between the B-ultrasound probe 1 and the surface of the eyeball. In this way, the wave-shaped connecting edge 231 can better fit the shape of the eyeball due to the complex structure of the eye and the irregular surface curvature, reducing the air gap between the probe and the eyeball. This fit can significantly improve the transmission efficiency of the ultrasonic signal, thereby obtaining clearer and more accurate ultrasonic images. For complex eye examinations such as retinal detachment and choroidopathy, details can be better captured and the accuracy of diagnosis can be enhanced.

[0044] In some embodiments, the thickness of the storage bowl 23 gradually thins from the bowl bottom to the bowl opening, and the thickness of the connecting edge 231 is less than the thickness of the bowl opening of the storage bowl 23.

[0045] In this way, the thickness of the connecting edge 231 is less than the thickness of the bowl opening of the storage bowl 23, which can effectively ensure that the connecting edge 231 deforms first before the bowl opening of the storage bowl 23 deforms, effectively protecting the eyeball. In this way, since the connecting edge 231 is relatively thin, it will deform first when it contacts the eyeball, rather than exerting a large rigid force on the eyeball like the thicker bowl opening, which can effectively disperse the pressure and reduce the local compression caused by the contact between the probe and the eyeball. Especially when the probe and the eyeball surface are not uniformly contacted, the risk of corneal scratching and conjunctival damage can be significantly reduced.

[0046] The implementation principle of the storage sleeve capable of temporarily storing coupling agent is as follows: before the user uses the B-ultrasound probe 1 to perform examination on the eye of the patient, the coupling agent is injected into the storage cavity 22 through the introduction pipe 41 and the one-way valve 42, and the coupling agent is gathered in the storage bowl 23. During the use process, if the coupling agent is lost and needs to be supplemented, the piston rod 33 is directly pressed, the piston rod 33 pushes the gas in the gas storage pipe 32, the gas in the gas storage pipe 32 is compressed to the telescopic air bag 31 through the vent hole 34, the telescopic air bag 31 is expanded to squeeze the coupling agent in the storage cavity, so that the coupling agent in the storage cavity 22 is squeezed into the storage bowl 23 for supplement, the through holes 24 are uniformly arranged in the storage bowl 23, which is convenient for uniformly extruding the coupling agent, the mark window 25 is used to determine the direction of the mark point 11 of the B-ultrasound probe 1 when the coupling agent storage sleeve 2 is sleeved on the B-ultrasound probe, and the axial position when the fixed sleeve is sleeved on the B-ultrasound probe 1 is controlled, so that the B-ultrasound probe 1 is prevented from being too deeply inserted, the connecting edge 231 is used to improve the adhesion to the surface of the eyeball and reduce the discomfort, the wavy connecting edge 231 ensures the softness, provides more variable volume for the inner cavity of the storage bowl 23 when adhesion, and facilitates the control of the adhesion degree of the B-ultrasound probe 1 to the surface of the eyeball, the thickness of the connecting edge 231 is less than the thickness of the bowl opening position of the storage bowl 23, which can effectively ensure that the connecting edge 231 can deform first before the bowl opening of the storage bowl 23 deforms, and the eyeball is effectively protected.

[0047] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
