Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0027] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] The following combination Figures 1 to 5 The utility model is described in detail.

[0029] An ultrasound probe protection device, in some embodiments, such as Figures 1 to 5As shown, it includes a protective shell 1, an attachment body 2 and a fixing mechanism; the protective shell 1 cooperates with the ultrasonic probe 3; the attachment body 2 is provided with a placement hole 4 on an opening, and the placement hole 4 is provided with an attachment mechanism for attaching an ultrasonic isolation sleeve to the end of the ultrasonic probe 3, and the attachment mechanism cooperates with the protective shell 1; the fixing mechanism is used to place an unused ultrasonic isolation sleeve 6; the interior of the attachment body 2 is also provided with a placement space 7 for installing the fixing mechanism; the interior of the attachment body 2 is also provided with an accommodating channel 8 for connecting the placement hole 4 and the placement space 7, and the unused ultrasonic isolation sleeve 6 on the fixing mechanism enters the attachment mechanism through the accommodating channel 8; the accommodating channel 8 is provided with a shearing component for cutting off the unused ultrasonic isolation sleeve 6 and the ultrasonic isolation sleeve 5 to be applied.

[0030] During specific use, the ultrasonic probe 3 is first installed in the protective shell 1, and the end of the ultrasonic probe 3 passes through the end of the protective shell 1; then the fixing mechanism is operated to move the unused ultrasonic isolation sleeve 6 on the fixing component into the attachment mechanism along the accommodating channel 8 to become the ultrasonic isolation sleeve 5 to be applied. At this time, the ultrasonic isolation sleeve 5 to be applied is located inside the placement hole 4, and then the medical staff inserts the end of the ultrasonic probe 3 into the placement hole 4 along the opening of the placement hole 4. During the insertion process, the protective shell 1 starts the shearing component movement to cut off the unused ultrasonic isolation sleeve 6 and the ultrasonic isolation sleeve 5 to be applied, and then the ultrasonic probe 3 continues to move downward along the placement hole 4, so that the ultrasonic isolation sleeve 5 to be applied is attached to the end of the ultrasonic probe 3 under the action of the attachment component, and then the medical staff pulls out the ultrasonic probe 3 outward and applies coupling agent on the surface of the ultrasonic isolation sleeve at the end of the ultrasonic probe 3, and then performs an ultrasonic examination on the patient. When the ultrasonic examination of a patient is completed, the ultrasonic isolation sleeve at the end of the ultrasonic probe 3 is removed, and the above procedure is repeated to replace a new ultrasonic isolation sleeve. This device can automatically apply an ultrasonic isolation sleeve to the end of the ultrasonic probe 3, and the ultrasonic isolation sleeve can be used for specific people. It can also isolate the end of the ultrasonic probe 3 from the patient's skin, preventing direct contact between the skin and the end of the ultrasonic probe 3, thereby wrapping and protecting the probe end and avoiding the spread of disease.

[0031] In some embodiments, as Figures 1 to 5 As shown, the fixing mechanism includes an opening and closing cover 9 threadedly connected to the placement space 7, and a mounting pin 10 is rotatably connected inside the opening and closing cover 9. The mounting pin 10 is provided at one end outside the opening and closing cover 9 and is provided with an operating button 11; the unused ultrasonic isolation sleeve 6 is wrapped around a sleeve 37 that cooperates with the mounting pin 10, and the internal end face of the placement space 7 is rotatably connected to a rotating disk that matches the end of the mounting pin 10.

[0032] During specific use, the sleeve 37 wrapped with the unused ultrasonic isolation sleeve 6 is installed on the mounting pin 10, and then the sleeve head is placed in the placement space 7, and the end of the mounting pin 10 is connected to the rotating disk inside the placement space 7, and then the end of the unused ultrasonic isolation membrane is inserted into the accommodating channel 8, and then the opening and closing cover 9 is threadedly connected to the placement space 7, and the operating button 11 is rotated to rotate the mounting pin 10, so that the unused ultrasonic isolation sleeve 6 enters the attachment mechanism along the accommodating channel 8 to become the ultrasonic isolation sleeve 5 to be applied.

[0033] It is worth mentioning that the ultrasonic isolation sleeve is a disposable ultrasonic isolation sleeve, which is prior art and therefore will not be elaborated on in detail. In addition, in the application, the application surface of the ultrasonic isolation sleeve is the side away from the sleeve 37.

[0034] In some embodiments, as Figures 1 to 5 As shown, the shearing mechanism includes a limiting plate 12 arranged above the placement hole 4, and the two ends of the limiting plate 12 are respectively fixedly connected with a first sliding plate 13, and the top of the attachment body 2 is provided with a first sliding groove 14 that cooperates with the first sliding plate 13; the bottom end of the first sliding groove 14 is provided below the accommodating channel 8; the bottom end of the first sliding plate 13 inside the first sliding groove 14 close to the placement space 7 is a sharp shearing end 15; the limiting plate 12 is provided with a through hole 16 that matches the protective shell 1, and a first spring 17 is provided between the limiting plate 12 and the top of the attachment body 2; the outside of the protective shell 1 is provided with an abutment component for pressing the limiting plate 12.

[0035] During specific use, after the unused ultrasonic isolation sleeve 6 enters the attachment mechanism along the accommodating channel 8 and becomes the ultrasonic isolation sleeve 5 to be applied, the medical staff inserts the end of the ultrasonic probe 3 into the placement hole 4 along the opening of the placement hole 4. During the insertion process, the abutment assembly on the protective shell 1 abuts against the top of the limiting plate 12, and presses the limiting plate 12 to overcome the first spring 17 and move downward. The first sliding plate 13 slides in the first sliding groove 14, and the first sliding plate 13 with the sharp shearing end 15 cuts off the unused ultrasonic isolation sleeve 6 and the ultrasonic isolation sleeve 5 to be applied in the accommodating channel 8.

[0036] In some embodiments, as Figures 1 to 5As shown, the abutment assembly includes an abutment ring 18 slidably connected to the outside of the protective shell 1, and the outer side of the protective shell 1 is provided with a second sliding groove 19 arranged in the vertical direction, and the inner side of the abutment ring 18 is provided with a second sliding plate 20, and the second sliding plate 20 is fitted inside the second sliding groove 19, and a second spring 21 is provided between the top of the second sliding plate 20 and the top of the second sliding groove 19, and the spring coefficient of the first spring 17 is greater than the spring coefficient of the second spring 21.

[0037] During specific use, the medical staff inserts the end of the ultrasound probe 3 into the placement hole 4 along the opening of the placement hole 4. During the insertion process, since the spring coefficient of the first spring 17 is greater than the spring coefficient of the second spring 21, the second spring 21 is gradually compressed during the downward movement of the ultrasound probe 3. At this time, the end of the ultrasound probe 3 abuts and pulls the ultrasound isolation cover 5 to be applied, so that the end of the ultrasound probe 3 is tightly attached to the ultrasound isolation cover 5 to be applied. At this time, the second spring 21 is in a compressed state, and then the limiting plate 12 overcomes the restoring force of the first spring 17, so that the limiting plate 12 is pressed down and moves, thereby cutting off the ultrasound isolation cover 5 to be applied and the unused ultrasound isolation cover 6.

[0038] It is worth mentioning that the first spring 17 returns the limiting plate 12 to its original position, and the second spring 21 returns the abutting ring 18 to its original position, thus preparing for the next attachment of the ultrasonic probe 3 .

[0039] In some embodiments, as Figures 1 to 5 As shown, the attachment mechanism includes a plurality of first receiving grooves 22 arranged around the inner wall of the placement hole 4 and at the same horizontal plane, and each of the first receiving grooves 22 is respectively provided with a first guide structure for applying the ultrasonic isolation sleeve 5 to be applied; the receiving channel 8 is arranged through the middle of the first receiving groove 22, and the first guide structure is arranged below the first receiving groove 22.

[0040] During specific use, when the operating button 11 is rotated, the ultrasonic isolation sleeve slides in the accommodating channel 8 and reaches the middle of all the first accommodating grooves 22. The ultrasonic isolation sleeve here is the ultrasonic isolation sleeve 5 to be applied; when the ultrasonic probe 3 moves downward, the first guide structure abuts against the outer edge of the ultrasonic isolation sleeve 5 to be applied so that it is completely fitted with the end of the ultrasonic probe 3 to complete the application.

[0041] In some embodiments, as Figures 1 to 5As shown, the first guide structure includes a third sliding groove 23 horizontally arranged on the side wall of the first accommodating groove 22, and the third sliding plate 24 is slidably connected inside the third sliding groove 23. A third spring 34 is provided between the third sliding plate 24 and the third sliding groove 23, and one side of the third sliding plate 24 is rotatably connected to the first guide wheel 25. The first guide wheel 25 is arranged inside the first accommodating groove 22 and abuts against the bottom surface of the ultrasonic isolation sleeve 5 to be applied.

[0042] During specific use, when the ultrasonic probe 3 moves downward, the first guide wheel 25, under the action of the third spring 34, abuts against the outer edge of the ultrasonic isolation sleeve 5 to be applied so that it is completely fitted with the end of the ultrasonic probe 3. At this time, the third spring 34 completes the application.

[0043] In some embodiments, as Figures 1 to 5 As shown, a second guide structure is further provided inside the first accommodating groove 22, and the second guide assembly is arranged above the accommodating channel 8; the second guide structure includes a fourth sliding groove 26 horizontally arranged on the side wall of the first accommodating groove 22, and the interior of the fourth sliding groove 26 is slidably connected to a fourth sliding plate 27, and a fourth spring 35 is provided between the fourth sliding plate 27 and the fourth sliding groove 26, and one side of the fourth sliding plate 27 is rotatably connected to a second guide wheel 28, and the second guide wheel 28 abuts against the top surface of the ultrasonic isolation sleeve to be applied.

[0044] During specific use, when the ultrasonic probe 3 is pulled out from the placement hole 4, the second guide wheel 28 can play a role in guiding and reducing friction, and under the action of the fourth spring 35, the edge of the ultrasonic isolation sleeve and the end of the ultrasonic probe 3 are squeezed for the second time to improve the attachment effect.

[0045] In some embodiments, as Figures 1 to 5 As shown, a sliding guide mechanism is further provided inside the attachment body 2, and the sliding guide mechanism is arranged between the placement space 7 and the first sliding plate 13 provided with a sharp shearing end 15, and the sliding guide mechanism includes second accommodating grooves 29 symmetrically arranged at the upper and lower ends of the accommodating channel 8, and each of the inner side walls of the second accommodating grooves 29 is respectively provided with a fifth sliding groove 30, and the interior of the fifth sliding groove 30 is slidingly connected to a fifth sliding plate 31, and a fifth spring 36 is provided between the fifth sliding plate 31 and the fifth sliding groove 30, and one side of the fifth sliding plate 31 is rotatably connected to a third guide wheel 32, and the third guide wheel 32 abuts against the upper and lower surfaces that are not applied with the ultrasonic isolation sleeve 6.

[0046] During specific use, the third guide wheel 32 guides the unused ultrasonic isolation sleeve 6 moving in the accommodating channel 8 under the action of the fifth spring 36 to prevent it from bending and deflecting during the movement.

[0047] In some embodiments, as Figures 1 to 5 As shown, a coupling agent placement groove 33 is slidably connected to the interior of the attachment body 2, and the coupling agent placement groove 33 is arranged below the placement opening.

[0048] During specific use, after the ultrasonic isolation sleeve is attached to the end of the ultrasonic probe 3, it continues to move downward, and the bottom end of the ultrasonic isolation sleeve can directly dip into the coupling agent in the coupling agent placement groove 33, eliminating the need for medical staff to manually add coupling agent.

[0049] In some other embodiments, different from the above embodiments, the outside of the protective shell 1 is wrapped with an anti-slip cover.

[0050] Specific usage principle:

[0051] First, the ultrasonic probe 3 is installed in the protective shell 1, and the end of the ultrasonic probe 3 passes through the end of the protective shell 1; then the fixing mechanism is operated to move the unused ultrasonic isolation sleeve 6 on the fixing component into the attachment mechanism along the accommodating channel 8 to become the ultrasonic isolation sleeve 5 to be applied. At this time, the ultrasonic isolation sleeve 5 to be applied is located inside the placement hole 4, and then the medical staff inserts the end of the ultrasonic probe 3 into the placement hole 4 along the opening of the placement hole 4. During the insertion process, the protective shell 1 starts the shearing component movement to cut off the unused ultrasonic isolation sleeve 6 and the ultrasonic isolation sleeve 5 to be applied, and then the ultrasonic probe 3 continues to move downward along the placement hole 4, so that the ultrasonic isolation sleeve 5 to be applied is attached to the end of the ultrasonic probe 3 under the action of the attachment component, and then the medical staff pulls out the ultrasonic probe 3 outward and applies coupling agent on the surface of the ultrasonic isolation sleeve at the end of the ultrasonic probe 3, and then performs an ultrasonic examination on the patient. When the ultrasonic examination of a patient is completed, the ultrasonic isolation sleeve at the end of the ultrasonic probe 3 is removed, and the above procedure is repeated to replace a new ultrasonic isolation sleeve. This device can automatically apply an ultrasonic isolation sleeve to the end of the ultrasonic probe 3, thereby realizing dedicated use for each patient and isolating the end of the ultrasonic probe 3 from the patient's skin, preventing direct contact between the skin and the end of the ultrasonic probe 3, thereby wrapping and protecting the probe end and avoiding the spread of disease.

[0052] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
