Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a coupling pad used for cardiac ultrasonic examination. Background Art

[0002] Cardiac ultrasound mainly checks whether there are any abnormalities in the morphology of the heart and whether the heart function is normal. According to the ASE guidelines, echocardiography is the preferred imaging examination method for heart disease. Cardiac color ultrasound is an instrument that can intuitively and dynamically display valvular diseases. Through color ultrasound examination, it can show the structure and function of the heart without any damage to the human body. The probe is like a camera lens. As the probe rotates in front of the patient's chest, the various structures of the heart can be clearly displayed on the screen.

[0003] At present, traditional medical ultrasound coupling agents are used for cardiac ultrasound examinations. They are mainly composed of propylene glycol, propylene glycol, etc. The purpose of the coupling agent is to improve the ultrasonic fit between the probe and the patient, and it is used on intact skin. During ultrasound examination, the coupling agent is directly applied to the left chest area, and the ultrasound probe is moved to scan various angles of the heart to obtain cardiac ultrasound images of different sections.

[0004] The patent with publication number CN210077698U discloses an easy-to-slide medical ultrasonic coupling pad, including a solid hydrogel body, characterized in that: a groove is provided on the top of the body, and a sticky layer is provided on the bottom of the groove. The utility model solves the problem of how to help medical personnel complete the synchronous movement of the ultrasonic coupling pad and the ultrasonic probe with only one hand, reduce the wear and aging caused by repeated friction of the ultrasonic probe, and at the same time do not affect the ultrasonic coupling pad to use its own deformability to fit the skin of different parts of the human body. And how to increase the moisture of the part of the ultrasonic coupling pad that contacts the human body to extend the detection time and improve the accuracy of the detection and diagnosis results.

[0005] During an echocardiogram, the probe is placed in the intercostal space of the left chest area, and an ultrasonic examination of the heart is performed through the intercostal space. In order to make the probe fit completely to the skin, the space between the skin and the probe is currently filled with a liquid-gel coupling agent. However, this is not a tight fit, and a clear cardiac ultrasound image cannot be obtained. Therefore, the operator needs to pressurize the probe very hard, which causes the patient to feel obvious pain during the examination. In addition, because the probe is relatively cold, it will cause discomfort to the patient when the probe touches the patient's skin, especially in winter.

[0006] During current clinical cardiac ultrasound examinations, when examining children or infants with narrow intercostal spaces, in order to ensure image clarity, the examiner sometimes fills a plastic glove with water and places it on the heart area as a temporary, crude coupling pad to assist in the examination. Utility Model Content

[0007] The purpose of the utility model is to provide a coupling pad for cardiac ultrasound examination, which overcomes the problem in the prior art that during the ultrasound examination of the patient, the probe is easily loosely fitted to the patient's skin. In order to ensure that a clear cardiac ultrasound image is obtained, the operator is required to press the probe hard, causing the patient to feel pain during the examination, and the cold coupling agent and probe will cause discomfort to the patient.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0009] A coupling pad for cardiac ultrasound examination is designed. A shrink sleeve is provided at the connection between the silicone body and the probe to ensure the stability of the probe and the silicone body when they are docked, prevent the two from easily separating, and ensure that the probe and the inlay groove fit tightly. The protective cover can well protect the bottom of the silicone body and can also be heated and disinfected to ensure its safety in use and avoid the cold feeling when it comes into contact with the patient's skin. The specific plan is as follows:

[0010] A coupling pad for cardiac ultrasound examination, comprising a silicone body and an inlay groove arranged at the center of the top of the silicone body, wherein the top of the silicone body is provided with a shrink sleeve covering the inlay groove and used for sleeve connection with a probe;

[0011] A protective cover is sleeved on the bottom of the silicone body, and a heating and disinfecting plate for heating and disinfecting the bottom of the silicone body is arranged inside the protective cover.

[0012] Preferably, the shrink sleeve is an elastic and shrinkable sleeve-shaped structure, and an elastic fastening ring is provided at the opening of the upper end of the shrink sleeve.

[0013] Preferably, ties are provided on the left and right sides of the protective cover respectively, an adhesive layer is provided on the inner side of the ties, and the adhesive layer is bonded to the side wall of the silicone body.

[0014] Preferably, the protective cover is sleeved on the lower end of the silicone body, a USB interface is used at the center of the protective cover, and the USB interface is connected to the heating and disinfection plate.

[0015] Preferably, the silicone body is a flat rectangular pad structure, and the inlay groove is a flat rectangular groove structure.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model provides a shrink sleeve at the connection between the silicone body and the probe. After the probe is inserted into the inlay groove and docked, it can be fastened by an elastic fastening ring to ensure the stability of the probe and the silicone body when docked, and prevent the two from being easily separated, so that the coupling pad can be stably and tightly fitted on the probe, so as to ensure that the ultrasonic wave can stably propagate into the heart, thereby obtaining clear cardiac ultrasonic images and improving the timely detection and diagnosis of heart diseases.

[0018] 2. The protective cover in the utility model can not only protect the silicone body, but also heat and disinfect the bottom of the silicone body through the heating and disinfection plate provided in the protective cover, so that the silicone body can be reused. The heating of the silicone body can avoid the discomfort caused by the coldness of the coupling pad to the patient, and the disinfection of the silicone body can avoid cross infection.

[0019] 3. The utility model adopts silica gel as the main body of the coupling pad. In order to obtain clear cardiac ultrasound images and further improve the detection rate of heart diseases, the attenuation of the sound wave propagation process can be reduced as much as possible during the ultrasound examination, which is more conducive to fitting the patient's skin. At the same time, it is compressible, which can reduce the pain of the probe directly squeezing the patient's skin. It can also be reused after disinfection, which can avoid the risk of cross infection and help reduce the waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1-2 As shown, the utility model provides a coupling pad for cardiac ultrasound examination, including a silicone body 1, and an inlay groove 11 arranged at the center position of the top of the silicone body 1, and a shrink sleeve 2 covering the inlay groove 11 and used for sleeve connection with the probe 6 is provided on the top of the silicone body 1.

[0032] As an optimization technical solution of the present invention, silicone material is used as the main body of the coupling pad, mainly to obtain clear cardiac ultrasound images and further improve the detection rate of heart diseases. It can not only meet its retractability and avoid the pain caused by the probe 6 squeezing on the patient's skin during the examination, but also disinfect it to avoid the risk of cross infection so that it can be reused. At the same time, the probe 6 can be embedded in the inlay groove 11 and the probe 6 is covered and connected by the shrink sleeve 2, so that the probe 6 will not be easily separated from the coupling pad body, which is more conducive to the close fit of the probe and the coupling pad body. Because the silicone body 1 is similar to a thick silicone sleeve on the probe 6, the friction between the probe and the skin can be reduced, thereby reducing the degree of probe wear and increasing the service life of the probe.

[0033] In the above solution, the shrink sleeve 2 is an elastic and shrinkable sleeve-shaped structure, and an elastic fastening ring 21 is provided at the opening of the upper end of the shrink sleeve 2.

[0034] As an optimization technical solution of the utility model, the shrink sleeve 2 adopts an elastic sleeve structure, which can ensure that the shrink sleeve 2 is always tightly fitted on the probe 6 to ensure the firmness of its connection. At the same time, the elastic fastening ring 21 plays an auxiliary fastening role, so that the probe 6 will not easily slip out of the embedding groove 11. At the same time, it can ensure that the probe and the embedding groove are tightly fitted to ensure the ultrasound imaging quality.

[0035] In the above solution, the silicone body 1 is a flat rectangular spacer structure, and the inlay groove 11 is a flat rectangular groove structure.

[0036] As an optimization technical solution of the utility model, the flat rectangular silicone body 1 is consistent with the bottom shape of the probe 6. At the same time, it is compressible due to the silicone material and can adapt to any part of the patient's skin, making it more conducive to fitting with the patient's skin. The flat rectangular inlay groove 11 can ensure that the probe 6 is effectively and tightly embedded, which is more conducive to the ultrasonic examination. Example 2

[0037] like Figure 3-6 As shown, on the basis of Example 1, the difference from Example 1 is that a protective cover 3 is sleeved on the bottom of the silicone body 1, which can not only protect the silicone body 1, but also prevent it from being infected; a heating and disinfection plate 4 for heating and disinfecting the bottom of the silicone body 1 is provided in the protective cover 3, and the heating and disinfection plate 4 can heat the bottom of the silicone body 1 to avoid its own cold feeling causing discomfort to the patient, so that it can be reused. At the same time, the bottom can also be disinfected by heating to avoid cross infection during repeated use.

[0038] In the above solution, ties 31 are respectively provided on the left and right sides of the protective cover 3 , and an adhesive layer 5 is provided on the inner side of the ties 31 , and the adhesive layer 5 is bonded to the side wall of the silicone body 1 .

[0039] As an optimized technical solution of the utility model, the ties provided on both sides of the protective cover 3 are bonded to the side of the silicone body 1 through the adhesive layer 5, which can prevent the protective cover 3 from falling off and improve its stability.

[0040] In the above solution, the protective cover 3 is sleeved on the lower end of the silicone body 1 , and a USB interface 41 is used at the center of the protective cover 3 , and the USB interface 41 is connected to the heating and disinfection plate 4 .

[0041] As an optimized technical solution of the present invention, the heating and disinfecting plate 4 can be powered on through the USB interface 41 so that the heating and disinfecting plate 4 can perform heating work.

[0042] Specific implementation cases:

[0043] When performing an echocardiogram, the probe 6 is placed in the intercostal space of the left chest area, and an ultrasonic examination of the heart is performed through the intercostal space. Before the examination begins, the wire is connected to the USB interface 41 to power the heating and disinfection plate 4, so that the bottom of the silicone body 1 can be heated. After the heating is completed, the bottom of the silicone body 1 is cooled to about 40 degrees, and then the silicone body 1 can be connected to the probe 6.

[0044] At that time, in order to make the probe 6 fit completely with the skin, the shrink sleeve 2 can be stretched open, and the probe 6 can be inserted from the elastic fastening ring 21 and embedded in the embedding groove 11 on the top of the silicone body 1, so that the silicone body 1 is connected to the probe 6, and the bottom of the silicone body 1 is tightly fitted with the skin of the patient's heart area, so as to perform ultrasonic examination. During the examination, the patient will not feel pain due to pressure, nor will the patient feel discomfort due to the cold feeling of the examination equipment, so that the patient can obtain clear and high-quality cardiac ultrasound images in a more comfortable examination. In addition, the coupling pad can be reused, which effectively helps to reduce the waste of resources and examination costs.

[0045] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
