JP7468366B2 - Sleeve sheet for protective cover of ultrasonic diagnostic equipment - Google Patents

Description

The present disclosure relates to a sleeve sheet for a protective cover for an ultrasonic diagnostic device.

Since it is relatively easy to observe inside the body using an ultrasound diagnostic device, its use in the medical field is expanding. Recently, portable ultrasound diagnostic devices that combine a probe and a monitor and can be used independently have been developed. Portable ultrasound diagnostic devices are easy to carry, and their uses are expanding beyond image diagnosis of organs such as the heart to include procedures such as puncture with a puncture needle and insertion of a catheter.

When an ultrasonic diagnostic device is used for puncturing a puncture needle, etc., it is required to prevent infection by bacteria, viruses, etc. during puncturing. For this reason, it has been proposed that when using an ultrasonic diagnostic device, the part of the probe that comes into contact with the human body should be sterilized, and that a sterilized protective cover should be attached to the probe so that the probe does not come into direct contact with the human body. In the case of a portable ultrasonic diagnostic device in which a probe and a monitor are integrated, it is difficult to sterilize the entire device, so the device is used with a bag-shaped protective cover attached (see, for example, Patent Document 1).

JP 2018-11766 A

It is preferable that the protective cover can completely accommodate the ultrasonic diagnostic device to prevent contamination, and can be in close contact with the ultrasonic diagnostic device so as not to affect the transmission and reception of ultrasonic waves. However, when the ultrasonic diagnostic device is inserted into the protective cover, the soft protective cover tends to twist and the ultrasonic diagnostic device tends to get caught, making it difficult to position the ultrasonic diagnostic device deep inside the protective cover.

Another independent problem is that when the ultrasound device is inserted into the cover, the device may come into contact with the exterior surface of the cover, potentially contaminating the exterior surface of the cover.

In addition, as a separate issue, in the case of a bag that is provided with a member that keeps the cover open, there is a risk that the bag's freedom of deformation will be reduced or the cover will move in an unintended direction, which may impair operability for the practitioner.

An object of the present disclosure is to make it possible to easily attach a bag-shaped protective cover to an ultrasonic diagnostic device.

A first aspect of the sleeve sheet of the present disclosure is directed to a sleeve sheet to be placed within a protective cover which is a bag-shaped body having an opening on one side for use with an ultrasonic diagnostic device, and the sleeve sheet comprises a first plate body and a second plate body, and the first plate body and the second plate body are arranged so that their tip ends are located at the axial center of the protective cover or closer to the bottom end than the axial center, and by pressing both side ends in the width direction of the protective cover towards the center, the first plate body and the second plate body deform so as to be separated from each other, thereby forming a space within the protective cover.

According to the first aspect of the sleeve sheet, by simply pressing both side ends of the bag-shaped protective cover, the bottom end side of the protective cover can be expanded to form and maintain a space. Therefore, when inserting the ultrasonic diagnostic device, the ultrasonic diagnostic device is less likely to get caught on the protective cover, and the acoustic lens of the ultrasonic diagnostic device can be reliably positioned at the bottom end of the protective cover.

In a first aspect of the sleeve sheet, the sleeve sheet is intended to be placed inside a bag-shaped protective cover for an ultrasonic diagnostic device, and the sleeve sheet may comprise a first plate body and a second plate body, and be arranged so that its tip is located closer to the bottom end than 1/2 of the length of the protective cover.

According to the first aspect of the sleeve sheet, by simply pressing both side ends of the bag-shaped protective cover, a space can be more reliably formed on the bottom end side of the protective cover and this space can be maintained, which makes it easier to attach the protective cover to the ultrasonic diagnostic device.

In a first aspect of the sleeve sheet, the sleeve sheet is intended to be placed inside a bag-shaped protective cover for an ultrasonic diagnostic device, and the sleeve sheet may be provided with a first plate body and a second plate body, and may be formed so that its axial length is longer than 1/2 of the axial length of the protective cover.

According to the first aspect of the sleeve sheet, a wide space can be formed and maintained in the axial direction of the protective cover simply by pressing both side ends of the bag-shaped protective cover, which makes it easy to attach the protective cover to an ultrasonic diagnostic device.

In the first aspect of the sleeve sheet, at least one of the first plate and the second plate can have a notch cut into at least a portion of the edge on the tip side. By adopting such a configuration, even if the protective cover is in a flat bag shape, the bottom end can be deformed three-dimensionally to greatly expand the space.

In the first aspect of the sleeve sheet, the cutout portion may be cut out at the center in the width direction on the tip side. By adopting such a configuration, when a gel or the like for improving adhesion is applied to the bottom end portion, the gel or the like is less likely to adhere to the sleeve sheet.

In the first aspect of the sleeve sheet, at least one of the first plate and the second plate may have leg portions extending in the distal direction on both sides in the width direction of the distal end side, and the leg portions may have a portion whose width increases toward the proximal end. By adopting such a configuration, it is possible to largely deform the bottom end portion while ensuring the strength of the leg portions.

A second aspect of the sleeve sheet is directed to a sleeve sheet that is placed within a protective cover, which is a bag-shaped body having an opening on one side for use with an ultrasonic diagnostic device, and the sleeve sheet protrudes from the opening to the outside of the protective cover and comprises a first plate body and a second plate body, and the first plate body and the second plate body are deformed so as to be separated from each other by pressing both side ends in the width direction of the protective cover toward the center, thereby forming a space within the protective cover.

According to the second aspect of the sleeve sheet, the opening edge of the cover can be opened reliably, reducing the possibility of the device touching the outer surface of the cover. In addition, the sleeve sheet acts as a guide to the protective cover opening, allowing the ultrasonic diagnostic device to be smoothly accommodated inside the protective cover.

In a second aspect of the sleeve sheet, the first plate and the second plate can have portions at the base end that do not overlap each other when the first plate and the second plate are disposed at the use position inside the protective cover. By adopting such a configuration, it becomes easy to remove the sleeve sheet after use.

A third aspect of the sleeve sheet is directed to a sleeve sheet that is placed within a protective cover, which is a bag-shaped body having an opening on one side for use with an ultrasonic diagnostic device, and the sleeve sheet is arranged so as to be removably arranged within the protective cover and comprises a first plate body and a second plate body, and when both side ends in the width direction of the protective cover are pressed toward the center, the first plate body and the second plate body deform so as to be separated from each other, thereby forming a space within the protective cover.

According to the third aspect of the sleeve sheet, an appropriate space is formed in the protective cover, and after the ultrasonic diagnostic device is housed in the protective cover, the first plate body and the second plate body are removed from the protective cover, thereby preventing the first plate body and the second plate body from hindering the deformability of the protective cover. In addition, the protective cover does not move in an unintended direction due to the weight of the rigid member or the like, and the operability of attaching the ultrasonic diagnostic device to the protective cover can be improved.

The sleeve sheet of the present disclosure makes it possible to easily attach a protective cover to an ultrasonic diagnostic device.

1 shows a state in which a sleeve sheet 101 is inserted into a protective cover 102, which is a bag-shaped body for an ultrasonic diagnostic device 103. In this embodiment, the protective cover 102 is a simple flat bag entirely made of film, with three sides closed, namely, a bottom end 102b and both side ends 102c and 102d, other than an opening end 102a of overlapping films.

The sleeve sheet 101 has a first plate body 111 and a second plate body 112. The first plate body 111 and the second plate body 112 are each a plate body having a higher rigidity than the film of the protective cover 102. In this embodiment, the first plate body 111 and the second plate body 112 have the same shape and are stacked upside down.

2, the first plate 111 and the second plate 112 are inserted into the protective cover 102 from the tip side and placed in the use position. In this embodiment, in the use position, the tip portions of the first plate 111 and the second plate 112 are in contact with the bottom end portion 102b of the protective cover 102, and the base ends protrude from the open end portion 102a of the protective cover 102.

When the first plate 111 and the second plate 112 are disposed in the use position, pressing both side ends 102c, 102d of the protective cover 102 toward the center with both hands or one hand deforms the protective cover 102 so that the center portions in the width direction are separated from each other. This causes the two sheets constituting the protective cover 102 to separate from each other, forming a space in the protective cover 102 from the opening end 102a to the bottom end 102b.

3 and 4 show the state in which the protective cover 102 is attached to the ultrasonic diagnostic device 103. The ultrasonic diagnostic device 103 is inserted into the space formed in the protective cover 102 from the acoustic lens 133 side. The existence of the sleeve sheet 101 stably maintains the expanded space, making it easy to insert the ultrasonic diagnostic device 103 to the back.

A gel or the like is placed on the portion of the bottom end 102b of the protective cover 102 that comes into contact with the acoustic lens 133 in order to improve adhesion before inserting the ultrasonic diagnostic device 103. A gel-like sheet or the like can be used instead of gel. After the bottom end 102b and the acoustic lens 133 are brought into close contact with each other via the gel or the like, the bracket 104 is fitted from the outside of the protective cover 102 to fix the ultrasonic diagnostic device 103 inside the protective cover 102.

In this embodiment, the acoustic lens 133 is placed on the bottom end 102b side of the protective cover 102, which is closed in advance, and therefore, unlike the case where the acoustic lens 133 is placed on the open end side, the risk of contamination due to incorrect sealing operations can be reduced.

By folding back the upper part of the protective cover 102 and fixing it with the seal 105, it is possible to prevent foreign matter from entering the protective cover 102 and to improve operability. It is preferable to fold back the upper part of the protective cover 102 to the side where the display 134 of the ultrasound diagnostic device 103 is not provided, because this does not impede visibility of the display 134.

The sticker 105 can be a normal reattachable sticker, but if some of the sticker can be peeled off and reattached and some of the sticker cannot be peeled off, the position will not shift and operability will be improved. Also, sticker 105 does not have to be attached to the surface of protective cover 102 in advance, and a separately prepared sticker may be used. Furthermore, if there is no problem with operability, the folded portion of protective cover 102 does not have to be fixed with a sticker or the like.

The bracket 104 may be provided with a puncture guide 106. Providing the puncture guide 106 makes it easy to insert the puncture needle at a predetermined position and angle while watching the display on the display of the ultrasonic diagnostic device 103. Note that operability can be improved by fitting the bracket 104 over the protective cover 102 to fix the ultrasonic diagnostic device 103, but the bracket 104 may be used as necessary, and a configuration without the bracket 104 is also possible.

The protective cover 102 is a bag formed of a thin film. Therefore, when the sleeve sheet 101 is not inserted, even if the both side ends 102c and 102d are pressed toward the center, the front and back sheets of the protective cover 102 are deformed together, making it difficult to open the opening end 102a. Even if it accidentally opens, it cannot be said that the operability is good. In addition, the protective cover 102 is designed to have a small clearance between the ultrasonic diagnostic device 103 and the acoustic lens 133 so that the acoustic lens 133 of the ultrasonic diagnostic device 103 can be easily positioned at the bottom end of the protective cover 102 and wrinkles or the like are not formed on the contact surface with the acoustic lens 133 when positioned at the bottom end, making it difficult to smoothly insert the ultrasonic diagnostic device 103 into the protective cover 102.

On the other hand, when the sleeve sheet 101 is inserted, pressing the both side ends 102c, 102d of the protective cover 102 toward the center also presses the first plate 111 and the second plate 112. The first plate 111 and the second plate 112 are thicker and more rigid than the protective cover 102, so that the central portions are deformed to separate from each other. Therefore, the opening end 102a of the protective cover 102 can be opened. Depending on the state of the first plate 111 and the second plate 112 and the degree of force applied, the first plate 111 and the second plate 112 may be deformed with their central portions in contact. However, by touching the base ends of the first plate 111 and the second plate 112 protruding from the opening end 102a of the protective cover 102 with a finger or the like, it is easy to induce the central portions to separate from each other.

In addition, the sleeve sheet 101 of this embodiment also has a function of making it difficult for the ultrasonic diagnostic device 103 to get caught on the protective cover 102 when the ultrasonic diagnostic device 103 is inserted into the protective cover 102. Due to the presence of the sleeve sheet 101, the protective cover 102 is less likely to twist, and the ultrasonic diagnostic device 103 can be easily pushed into the bottom end 102b of the protective cover 102. In addition, the presence of the sleeve sheet 101, which has a smaller friction than the protective cover 102, between the ultrasonic diagnostic device 103 and the protective cover 102 improves the sliding of the ultrasonic diagnostic device 103 and makes it easier to insert it. For this reason, it is preferable to smooth the surface of the sleeve sheet 101 to reduce friction. In addition, the sleeve sheet 101 also has the advantage that the protective cover 102 is less likely to be damaged when the ultrasonic diagnostic device 103 is inserted. The sleeve sheet 101 can be removed after the ultrasonic diagnostic device 103 is completely inserted into the protective cover 102, but it is also possible to slide the ultrasonic diagnostic device 103 into the protective cover 102 by pulling out the sleeve sheet 101 while the ultrasonic diagnostic device 103 is partway inserted.

In the case of a flat bag-shaped protective cover 102 that does not have a gusset at the bottom end 102b, simply pulling the front and back sheets apart at the opening end 102a may limit the deformation of the bottom end 102b, making it impossible to significantly expand the space near the bottom end 102b.

In this embodiment, the first plate 111 and the second plate 112 each have a tip notch 113 in which the center in the width direction is cut out on the tip side. Therefore, the center on the tip side of the first plate 111 and the second plate 112 does not contact the bottom end 102b of the protective cover 102, and only the leg-like parts 114 on both side ends contact the bottom end 102b of the protective cover 102.

As shown in Fig. 2, when the first plate 111 and the second plate 112 having the tip notch 113 are inserted into the protective cover 102 from the tip side and deformed so that the central portions are separated, the bottom end 102b of the protective cover 102 is deformed three-dimensionally along the tip notch 113 toward the opening end 102a. Therefore, even in the flat bag-shaped protective cover 102, the space near the bottom end 102b can be greatly expanded. The operation of storing the ultrasonic diagnostic device is performed by two people, one who keeps the protective cover 102 open and one who inserts the ultrasonic diagnostic device, taking into consideration the risk of contamination. The person who keeps the protective cover 102 open maintains the open state of the protective cover 102 with both hands or one hand, and the person who inserts the ultrasonic diagnostic device first drips a liquid such as gel toward the center of the width direction of the bottom end. Thereafter, the person inserting the ultrasonic diagnostic device places the ultrasonic diagnostic device in the protective cover 102 via the sleeve sheet 101 so that the person inserting the ultrasonic diagnostic device does not come into contact with the outer surface of the protective cover 102 with his/her fingers, and then detaches the sleeve sheet 101 from the protective cover 102. Since noise will be generated if there are air bubbles or wrinkles between the acoustic lens 133 and the skin, the opening side of the protective cover 102 is folded back and fixed with a seal or the like while an adhesive force is applied between the acoustic lens 133 and the protective cover 102 to prevent slackness or the like from occurring in the protective cover 102.

In this embodiment, the tip notch 113 is arc-shaped, but it may be triangular or rectangular. However, it is preferable to make the tip notch 113 arc-shaped or triangular, and the leg portion 114 gradually wider from the tip to the base end. This ensures the strength of the leg portion 114, and the leg portion 114 can firmly hold the side end of the bottom end 102b of the protective cover 102, and the bottom end 102b can be more easily deformed because the tip side is largely cut out. Note that the leg portion 114 only needs to have a portion that expands toward the base end, and the entire leg portion 114 does not need to be shaped to widen from the tip to the base end. In addition, it is preferable to make the tip notch 113 and the leg portion 114 curved to avoid corners, since this makes it difficult for the protective cover 102 to be damaged or torn.

Providing the tip notch 113 at the center of the first plate 111 and the second plate 112 also provides the advantage of not interfering with the application of gel or the like to the bottom end 102b of the protective cover 102 to improve adhesion with the acoustic lens 133. If gel or the like adheres to the tip of the sleeve sheet, the gel may adhere to the inner surface of the protective cover 102 other than the bottom end 102b or to the ultrasonic diagnostic device 103 when the sleeve sheet 101 is removed. However, by providing the tip notch 113 at the center where the gel or the like is applied, it is possible to suppress the adhesion of the gel or the like to the sleeve sheet 101. In addition, even if gel or the like adheres to the leg-shaped parts at both ends, the gel is less likely to adhere to the display 134 arranged in the center, and the situation in which visibility is reduced can be reduced.

5, both ends on the tip side of the first plate 111 and the second plate 112 may be cut out to provide tip notches 113A, and a leg-like portion 114A may be left in the center. Also, a leg-like portion may be left at one side end, and the other side end may be cut out.

6, if the insertion depth of the first plate 111 and the second plate 112 is adjusted so that the tips of the first plate 111 and the second plate 112 do not come into contact with the bottom end 102b of the protective cover 102, it is not necessary to provide a notch at the tip. In this case, it is preferable that the length of the part of the first plate 111 and the second plate 112 inserted into the protective cover 102 is longer than 1/2 or 1/2 of the axial length of the protective cover 102. If the first plate 111 and the second plate 112 are present up to a position on the bottom end 102b side beyond 1/2 or 1/2 of the axial length of the protective cover 102, the space can be neatly expanded from the opening end 102a to the bottom end 102b. However, the first plate body 111 and the second plate body 112 do not have to reach 1/2 the length of the protective cover 102, and it is possible to expand the space from the opening end 102a to the bottom end 102b even if the first plate body 111 and the second plate body 112 are simply close to the axial center of the protective cover.

In Fig. 6, an example is shown in which the first plate 111 and the second plate 112 are provided at their base ends with ears 116 wider than the protective cover 102 to prevent the tips of the first plate 111 and the second plate 112 from contacting the bottom end 102b of the protective cover 102. However, as in the third modified example shown in Fig. 7, a protective cover 102A having a width narrower than the first plate 111 and the second plate 112 at the bottom end 102b can be used to prevent the tips of the first plate 111 and the second plate 112 from contacting the bottom end 102b of the protective cover 102. Also, without providing a mechanism for limiting the insertion depth of the first plate 111 and the second plate 112, the first plate 111 and the second plate 112 may be pulled out slightly during operation to prevent the tips of the first plate 111 and the second plate 112 from contacting the bottom end 102b of the protective cover 102.

In addition, as shown in the fourth modified example in Fig. 8, in the case of a protective cover 102B having a gusset (gusset) 121 at the bottom end 102b, even if the first plate 111 and the second plate 112, which do not have a notch, are inserted to a position where they contact the bottom end 102b, the space can be expanded neatly from the opening end 102a to the bottom end 102b. In Fig. 8, a protective cover having a gusset at the bottom is shown, but a side gusset may be provided, or gussets may be provided at both the bottom and the side. Note that the sleeve sheet 101 having a tip notch can also be used for the protective cover 102B having a gusset.

The first plate 111 and the second plate 112 may be integrated rather than being two independent members. For example, the sides of the first plate 111 and the second plate 112 may be joined together by gluing or welding. The joining may be of the entire side or a part of the side. In addition, both the left and right sides may be joined, or only one side may be joined. Furthermore, the first plate 111 and the second plate 112 may be integrated by folding a single plate in half.

Although the first plate 111 and the second plate 112 have the same shape and are used by swapping the left and right sides, the first plate 111 and the second plate 112 may have different shapes. In this case, as in the fifth modified example shown in Fig. 9, the first plate 111 may have ears 116 and a shape in which the tip does not reach the bottom end 102b of the protective cover 102, and the second plate 112 may have a tip notch 113 at its tip. The second plate 112 may have a shape with notches on both sides.

In this embodiment and each modified example, the base end of the first plate 111 and the second plate 112 are provided with an oblique base end notch 115. By providing the base end notch 115, the base ends of the first plate 111 and the second plate 112 are provided with non-overlapping portions. Since one plate can be easily pinched or pushed, the state in which the first plate 111 and the second plate 112 deform in the same direction can be easily eliminated. The base ends of the first plate 111 and the second plate 112 may be provided with non-overlapping portions by other methods other than the notch. Moreover, the non-overlapping portions may be provided as necessary, or may not be provided.

Furthermore, by having the base ends of the first plate 111 and the second plate 112 protrude from the opening end 102a of the protective cover 102, the opening end 102a of the protective cover 102 can be maintained in an open state and the plates can be used as guide members for the protective cover 102, improving operability, but they do not have to protrude from the opening end 102a.

The sleeve sheet 101 of this embodiment and each of the modified examples can be removed from the protective cover 102 when operating the ultrasonic diagnostic device 103, which provides the advantage of not getting in the way when using the ultrasonic diagnostic device. However, the ultrasonic diagnostic device 103 can also be used with the sleeve sheet 101 inserted in the protective cover 102. In this case, it is preferable to make the shape of the sleeve sheet smaller than the ultrasonic diagnostic device 103 and shift the entire sleeve sheet to a position to the side of the ultrasonic diagnostic device 103 so as not to hinder the deformability of the bag as much as possible.

The sleeve sheet 101 can be stored and transported separately from the protective cover 102, and inserted into the protective cover 102 when in use. Also, the sleeve sheet 101 can be stored and transported in a state where it is inserted into the protective cover. In this case, in order to prevent the sleeve sheet 101 from coming out of the protective cover 102 during transportation, etc., the portion of the sleeve sheet 101 protruding from the open end of the protective cover 102 and the upper part of the protective cover 102 can be fixed with tape or the like.

Also, as shown in Fig. 10, the sleeve sheet 101 may be joined to the vicinity of the upper end of the protective cover 102 by spot welding or the like. In this case, if a separation portion 124 including a joining portion 123 of the protective cover 102 is separated from a main body portion 125 of the protective cover 102, the sleeve sheet 101 can be easily removed. In Fig. 10, an example in which a tip notch portion 113 is provided in the center of the sleeve sheet 101 is shown, but a similar configuration can be adopted for the sleeve sheet 101 of other modified examples. However, in this case, even if the sleeve sheet 101 does not have an ear portion or the like, the tip of the sleeve sheet 101 can be prevented from contacting the bottom end portion 102b of the protective cover 102.

Furthermore, as shown in Fig. 11, by inserting the sleeve sheet 101 and sealing the protective cover 102, the inside of the protective cover 102 can be easily kept clean. In the example shown in Fig. 11, a detachable tear-off portion 126 is provided at the upper part of the protective cover 102. Therefore, when in use, by tearing off the part above the tear-off portion 126, the base end of the sleeve sheet 101 protrudes from the open end of the protective cover 102, making operation easy. The configuration is not limited to this, and the upper part of the protective cover 102 may be folded back and secured with tape or the like.

The protective cover 102 is not particularly limited as long as it is a transparent bag capable of housing the ultrasonic diagnostic device 103, and may be a bag formed of a film made of polyethylene, polypropylene, polyethylene terephthalate, or the like. The film forming the protective cover 102 is preferably thin from the viewpoint of not affecting imaging, depending on the material, and is preferably 0.1 mm or less, more preferably 0.05 mm or less. In addition, from the viewpoint of tear resistance, it is preferably 0.005 mm or more, more preferably 0.001 mm or more.

The shape of the protective cover 102 is not particularly limited, and in the case of a flat bag, it can be a side-sealed bag in which a sheet of film is folded in half and separated while sealing two sides, a three-sided sealed bag in which two sheets of film are overlapped and sealed on three sides, or a palm-sealed bag in which a sheet of film is formed into a cylindrical shape and the back and bottom are sealed. In addition to a flat bag, it can also be a gusseted bag with a gusset. The protective cover 102 can be a bag-like body entirely formed from a film, but it may also be a bag-like body composed of a cylindrical film body and a gel sheet fixed to one opening of the film body.

The first plate 111 and the second plate 112 may be any plate that is more rigid than the film of the protective cover 102 and can be deformed to bend by applying a force from both ends toward the center. For example, the first plate 111 and the second plate 112 may be a sheet made of polyethylene, polypropylene, polyethylene terephthalate, or the like that is thicker than the protective cover 102. Although it depends on the material, from the viewpoint of facilitating the formation of a space within the protective cover 102, the thickness is preferably 0.05 mm or more, more preferably 0.1 mm or more, and also preferably 0.5 mm or less, more preferably 0.3 mm or less.

The first plate 111 and the second plate 112 preferably have smooth surfaces so that the ultrasonic diagnostic device 103 can be easily inserted into the protective cover 102. It is also preferable that the corners of the first plate 111 and the second plate 112 are chamfered, and in particular, the corners on the tip side and the leg-like portion that contacts the bottom end 102b are chamfered. By chamfering the corners, it is possible to make the protective cover 102 less likely to be scratched or torn by the first plate 111 and the second plate 112.

In the present embodiment and each of the modified examples, an example is shown in which a protective cover is attached to an ultrasonic diagnostic device having an acoustic lens, which is an ultrasonic sensor, at the tip of a rectangular housing and a display on one side, but the sleeve sheet shown in the present embodiment and each of the modified examples can be used when attaching a protective cover to any ultrasonic diagnostic device. Moreover, the sleeve sheet can be used not only for ultrasonic diagnostic devices in which the part where the acoustic lens is provided and the display part are integrated, but also for ultrasonic diagnostic devices in which they are separate.

The sleeve sheets of the present embodiment and each of the modified examples have a combination of multiple configurations to solve multiple problems that occur when attaching a protective cover to an ultrasonic diagnostic device.
