In the cover of Patent Document 1, the ultrasonic diagnostic device is inserted through the opening of the cover body as described above. May become contaminated. In addition, when the person who performs the work of closing the opening accidentally touches the outer peripheral surface of the opening with the glove and further touches other than the opening with the contaminated glove or the like, the contaminated area is enlarged. Therefore, it is preferable to insert the ultrasound diagnostic apparatus into the cover so as not to touch the outer peripheral surface of the opening, but it is not easy to insert the ultrasound diagnostic apparatus without touching it.

Therefore, according to the present invention, even if the outer surface of the opening is contaminated when the ultrasonic diagnostic apparatus is put into the cover main body, the contamination spreads from the contaminated portion on the outer surface of the opening to areas other than the opening. It is an object of the present invention to provide a cover for an ultrasonic diagnostic apparatus capable of suppressing the occurrence of vibration, and an ultrasonic diagnostic apparatus with the cover.

A cover for an ultrasonic diagnostic apparatus of the present invention comprises a casing, a probe disposed at one end of the casing in a predetermined direction and having a sensor for receiving ultrasonic waves reflected at a site to be inspected, and provided on the casing and and a monitor that displays an image corresponding to the ultrasonic waves received by the sensor. and a body portion capable of housing the entire ultrasonic diagnostic apparatus, wherein the separation portion is configured to be separable from the body portion.

According to the present invention, even if the outer surface of the opening is contaminated when inserting the ultrasonic diagnostic apparatus, the separating portion is separated from the main body to remove the contaminated portion on the outer surface of the opening from the portion other than the opening. It is possible to suppress the spread of contamination. For example, spread of contamination can be suppressed by dividing roles between the gripper and the inserter as follows. That is, a holder holds the main body portion so as to open the opening, and an inserter inserts the ultrasonic diagnostic apparatus through the opening. After insertion, the inserter can detach the separation portion containing the opening from the body portion to remove the opening with the contaminated site on the outer surface from the cover. As a result, it is possible to suppress the spread of contamination from the contaminated site to portions other than the opening.

According to the present invention, even when the outer surface of the opening is contaminated, it is possible to suppress the spread of contamination from the contaminated site to the portion other than the opening.

Also, the cover-equipped ultrasonic diagnostic apparatus 1 described below is merely an embodiment of the present invention. Therefore, the present invention is not limited to the embodiments, and additions, deletions, and modifications can be made without departing from the spirit of the invention.

<Ultrasound diagnostic device with cover>
The cover-equipped ultrasonic diagnostic apparatus 1 shown in FIG. 1 is used when puncturing a needle or the like while visualizing a subcutaneous blood vessel or the like, for example, when a catheter is placed in a blood vessel in dialysis treatment. The covered ultrasonic diagnostic apparatus 1 having such functions includes an ultrasonic diagnostic apparatus 2 and an ultrasonic diagnostic apparatus cover 3. The ultrasonic diagnostic apparatus 2 is covered with the ultrasonic diagnostic apparatus cover 3. used. An example of the configuration of the ultrasonic diagnostic apparatus 2 and the ultrasonic diagnostic apparatus cover 3 will be described below.

<Ultrasound diagnostic equipment>
The ultrasonic diagnostic apparatus 2 oscillates ultrasonic waves to a test site (i.e., subcutaneous tissue) while being applied to the body surface, and receives ultrasonic waves reflected from the test site (i.e., reflected waves). . Further, the ultrasonic diagnostic apparatus 2 performs image processing based on the received reflected waves, and projects a cross section of the test site. The ultrasonic diagnostic apparatus 2 having such functions has a casing 11 , a probe 12 and a monitor 13 . The casing 11 is made of a synthetic resin such as polycarbonate, ABS (acrylonitrile-butadiene-styrene) resin, SAS (silicon-acrylonitrile-styrene), or polypropylene, and is a generally rectangular box with a flat cross section when viewed from the front. . A distal end portion 11a, which is one end portion of the casing 11 in a predetermined direction, is formed in a trapezoidal shape that tapers toward the distal end. That is, the ultrasonic diagnostic apparatus 2 has a probe 12 at its distal end portion 2a. A monitor 13 is arranged on the front face 11c of the intermediate portion of the casing 11, and an image is displayed on the monitor 13. As shown in FIG. The probe 12 and monitor 13 are described in more detail below.

The probe 12 is configured to transmit and receive ultrasonic waves and has a sensor 12a. The sensor 12a is composed of, for example, a vibrator such as a piezoelectric element and an acoustic lens. The sensor 12a configured in this manner is attached so as to be embedded in the distal end portion 11b of the casing 11, and the lower end surface of the sensor 12a is substantially flush with the distal end surface of the casing 11. As shown in FIG. The sensor 12a arranged in this manner is connected to a control device (not shown) housed in the casing 11, and oscillates ultrasonic waves according to commands from the control device. Further, the sensor 12a receives a reflected wave reflected by the test site and outputs a signal corresponding to the received ultrasonic wave to the control device. The control device has an image processing function, performs image processing based on the signal, and outputs image data to the monitor 13 . The monitor 13 is, for example, a liquid crystal monitor or an organic EL monitor, and is configured to be able to display an image corresponding to image data. A cross-section of the inspection site is displayed.

In the ultrasonic diagnostic apparatus 2 configured in this manner, the probe 12 is brought into contact with the body surface of the test site, and the sensor 12a oscillates ultrasonic waves in this state. The oscillated ultrasonic waves are reflected at the test site, and the sensor 12a receives the reflected waves reflected at the test site and outputs a signal corresponding to the received ultrasonic waves to the control device. The control device performs image processing based on the signal and causes the monitor 13 to display the cross section of the site to be examined. This allows the user to scan the ultrasonic diagnostic apparatus 2 while viewing both the site to be examined and the cross-sectional image.

In the ultrasonic diagnostic apparatus 2 having such functions, blood or the like may adhere during puncturing, etc. Therefore, it is preferable to sterilize the apparatus each time it is punctured. However, in the ultrasonic diagnostic apparatus 2, the monitor 13 is not waterproofed, and if the ultrasonic diagnostic apparatus 2 is sterilized, problems may occur. Therefore, it is not easy to sterilize the ultrasonic diagnostic apparatus 2 . Therefore, the ultrasonic diagnostic apparatus 2 is covered with the ultrasonic diagnostic apparatus cover 3 so that the ultrasonic diagnostic apparatus 2 can be used without being sterilized. The ultrasonic diagnostic apparatus cover 3 will be described below.

<Cover for ultrasonic diagnostic equipment>
The ultrasonic diagnostic apparatus cover 3 covers the entire ultrasonic diagnostic apparatus 2 so as to prevent blood or the like from adhering to the ultrasonic diagnostic apparatus 2 or to prevent blood or the like adhering therefrom from scattering. is covered. The ultrasonic diagnostic apparatus cover 3 having such functions forms a bag shape including a tubular body 21, a bracket 22 with a guide, and a probe cover body 23 (see FIG. 2). The cylindrical body 21 is a highly transparent soft body made of a material such as polyethylene, polypropylene, polyethylene terephthalate, and polyvinyl chloride, and is a sterile soft body that has been sterilized. As shown in FIGS. 1 and 2, the cylindrical body 21 made of such a material is formed in a substantially rectangular shape elongated in the vertical direction when viewed from the front. The outer shape of the cylindrical body 21 is similar to that of the ultrasonic diagnostic apparatus 2 when viewed from the front, and the lower end side portion 21a is formed in a trapezoidal shape that tapers toward the lower end 21b. Further, the cylindrical body 21 is formed in a cylindrical shape so that the ultrasonic diagnostic apparatus 2 can be accommodated therein. The cylindrical body 21 configured in this manner has openings 21c and 21d at its upper and lower ends, respectively, and the openings 21c and 21d are configured as follows.

When the upper opening 21c, which is the first opening, is opened in the front-rear direction, it can be made substantially flat in plan view from above, and when opened, the outer shape of the upper opening 21c is smaller than the outer shape of the ultrasonic diagnostic apparatus 2. formed large. The upper opening 21c allows the ultrasonic diagnostic apparatus 2 to be inserted therethrough. The cylindrical body 21 has a separation portion 24 and a main body portion 25. The upper end portion including the upper opening 21c forms the separation portion 24, and the remaining portion forms the main body portion 25. ing. In addition, the separating portion 24 is separable (that is, separable) from the main body portion 25, which is the remaining portion. A separation region 26 is formed therebetween. The separation portion 26 is formed along the entire circumference of the cylindrical body 21, and is, for example, a perforation in which a plurality of holes are formed at intervals in the circumferential direction. The separation part 26 is arranged upwardly by a predetermined distance L from the lower end 21b of the cylindrical body 21, and the predetermined distance L is the sum of the vertical length of the ultrasonic diagnostic apparatus 2 and its thickness in the front-rear direction. That's it.

Further, the tubular body 21 is composed of a tubular member 28 with both ends opened, and is formed as follows. That is, the tubular body 21 is formed by folding back one opening side portion 28a of the tubular member 28 inward along the entire circumference, and the upper end after folding forms an upper opening 21c. Moreover, one opening side portion 28 a is arranged inside the separation portion 24 by folding back to form an inner cylindrical portion 27 . The inner cylindrical portion 27 formed in this manner extends from the upper opening 21c beyond the separation portion 26 to the main body portion 25, and covers the separation portion 26 from the inside along the entire circumference in the circumferential direction. The lower opening 21d is constructed as described below with respect to the upper opening 21c constructed as described above.

That is, the lower opening 21d, which is the second opening, has the lower end side portion 21a formed in an inverted trapezoidal shape as described above, and has a smaller diameter than the upper opening 21c. Therefore, after the ultrasonic diagnostic device 2 is inserted through the upper opening 21c of the tubular body 21, the distal end portion 2a of the ultrasonic diagnostic device 2 is naturally guided to the lower opening 21d. Further, the lower opening 21d is formed slightly larger than the outer peripheral shape of the distal end portion 2a of the ultrasonic diagnostic apparatus 2 in a state where the ultrasonic diagnostic apparatus 2 is inserted into the cylindrical body 21. The distal end portion 2a of the ultrasonic diagnostic apparatus 2 can be protruded from the. The lower opening 21d having such a shape is provided with a guide-equipped bracket 22 for attaching a probe cover body 23, which will be described in detail later.

The bracket 22 with guide has a bracket body 31 and a guide portion 32 . The bracket body 31 is made of a material harder than the probe cover body 23 to be described later, such as synthetic resin such as polycarbonate, ABS (acrylonitrile-butadiene-styrene) resin, SAS (silicon-acrylonitrile-styrene), and polypropylene. The bracket body 31 made of such material has a substantially plate-like shape as shown in FIGS. . In addition, in FIG. 3, the guide part 32 is not illustrated for convenience of explanation.

In the bracket body 31 having such a shape, the inner hole 31a is tapered downward (see FIG. 4). The inner hole 31a is formed slightly larger than the external shape of the distal end portion 2a of the ultrasonic diagnostic apparatus 2, so that the distal end portion 2a of the ultrasonic diagnostic apparatus 2 can be protruded. A pair of locking pieces 33, 33 are integrally formed on the bracket main body 31 configured in this manner so as to hold the ultrasonic diagnostic apparatus 2 with the distal end portion 2a protruding.

The pair of locking pieces 33 , 33 are plate-like members extending obliquely upward from the upper surface of the bracket body 31 so as to spread outward. The pair of locking pieces 33, 33 arranged in this way are arranged so that their main surfaces are opposed to each other, and the front end portion 11a of the casing 11 is inserted between the main surfaces. It's like A locking hole 33a is formed in each main surface of the pair of locking pieces 33, 33. As shown in FIG. Furthermore, a pair of fitting protrusions 11d, 11d (see FIG. 1) are formed on the side surface of the casing 11 so as to correspond to each locking hole 33a. Therefore, when the ultrasonic diagnostic apparatus 2 is inserted into the bracket main body 31 to a predetermined position, the pair of fitting protrusions 11d and 11d are fitted into the corresponding locking holes 33a, respectively. The ultrasonic diagnostic device 2 is locked and held by the bracket body 31 .

The shape of the outer peripheral surface of the bracket main body 31 configured in this way is formed to be substantially the same as the shape of the lower opening 21d. That is, the bracket main body 31 is placed in the lower opening 21d of the tubular body 21, and the lower opening 21d of the tubular body 21 is fixed to the outer peripheral surface of the bracket main body 31 over the entire circumference. The target is welded. Thus, the bracket main body 31 is provided at the lower opening 21d of the tubular body 21, and the probe cover body 23 is provided on the tubular body 21 via the bracket main body 31. As shown in FIG.

The probe cover body 23 has good acoustic coupling and is configured to be stretchable, and is made of, for example, a styrene-, urethane-, or silicone-based elastomer gel (styrene-based elastomer gel in this embodiment) material. The probe cover body 23 made of such a material has a substantially flat plate-like shape and is formed in a substantially oblong rectangular shape in a plan view. More specifically, the probe cover body 23 has a shape similar to that of the inner hole 31a of the bracket body 31 in plan view, and is slightly larger than the inner hole 31a. The probe cover body 23 configured in this way is fixed to the bracket body 31, and the bracket body 31 is configured as follows to fix the probe cover body 23. As shown in FIG.

That is, the bracket body 31 is composed of two upper and lower members, that is, a first bracket portion 34 and a second bracket portion 35, as shown in FIG. The first bracket portion 34 and the second bracket portion 35 are both horizontally elongated, flat and ring-shaped in plan view, and are formed in substantially the same shape. The first bracket portion 34 is provided with a pair of locking pieces 33, 33 on its upper surface, which are placed on the second bracket portion 35 so as to overlap and engage with each other. In addition, the outer peripheral edge of the probe cover body 23 is interposed between the two bracket parts 34 and 35, and the probe cover body 23 has the two bracket parts 34 and 34 along the entire peripheral edge in the circumferential direction. It is sandwiched by 35. As described above, the probe cover body 23 is fixed to the bracket main body 31 by being sandwiched between the two bracket parts 34 and 35 , and is provided on the cylindrical body 21 via the bracket main body 31 .

As described above, in the ultrasonic diagnostic apparatus cover 3, the lower opening 21d is closed by providing the probe cover body 23 in the lower opening 21d of the cylindrical body 21. By closing the lower opening 21d, the ultrasonic diagnostic apparatus is operated. A cover 3 is formed in the shape of a bag. More specifically, the ultrasonic diagnostic apparatus cover 3 is composed of a bag-like member 20 composed of a tubular member 28 , a bracket 22 with a guide, and a probe cover body 23 . One side of the bag-shaped member 20 is open, and the opening-side portion 20a (that is, one opening-side portion 28a of the tubular member 28) is folded back inward as in the case of forming the tubular body 21. . The ultrasonic diagnostic apparatus cover 3 having the inner cylindrical portion 27 is formed by the bag-like member 20 with the opening side portion 20a folded in this way. In the ultrasonic diagnostic apparatus cover 3 formed in this manner, a guide portion 32 is provided on the bracket body 31 as shown in FIGS.

The guide part 32 is for guiding the needle 41 of a needle device such as an indwelling needle to determine the puncturing direction when the needle 41 is punctured, and is formed in a roughly block shape. The guide portion 32 having such a shape is integrally attached to the front surface of the second bracket portion 35 . Note that the guide portion 32 does not necessarily have to be provided on the second bracket portion 35 and may be provided on the front surface of the first bracket portion 34 . Further, the guide portion 32 is attached to the bracket body 31 so that the front end surface 32a of the guide portion 32 is tilted forward by a predetermined angle with respect to the front surface of the second bracket portion 35 . A guide hole 32b is formed through the guide portion 32 in the vertical direction, and the guide hole 32b forms a predetermined angle forward with respect to the front surface of the second bracket portion 35, like the front end surface 32a. ing. Further, the guide hole 32b is formed so that the needle 41 can be inserted, and is configured so that the needle tip 41a can be protruded from therebelow and the puncture site can be punctured. Further, the front end surface 32a of the guide portion 32 is formed with an extraction opening 32c, and the extraction opening 32c is formed so that the needle 41 inserted into the guide hole 32b can be tilted forward and pulled out.

<Installation work and puncture work>
In the following, a mounting operation of covering the ultrasonic diagnostic apparatus cover 3 to use the ultrasonic diagnostic apparatus 2 will be described. The mounting work is performed by two persons, an inserter who inserts the ultrasonic diagnostic apparatus 2 and a holder who holds the ultrasonic diagnostic apparatus cover 3 . The ultrasonic diagnostic apparatus cover 3 is placed in a bag such as a sterile pack (not shown) to maintain a sterile condition, and the ultrasonic diagnostic apparatus cover 3 is taken out of the sterile pack by a holder when used. After taking it out, the holder opens the upper opening 21c of the tubular body 21 of the ultrasonic diagnostic apparatus cover 3 back and forth, and then the inserter inserts the ultrasonic diagnostic apparatus 2 from the distal end 2a into the upper opening 21c. do.

After that, in order to accommodate the entire ultrasonic diagnostic apparatus 2 in the tubular body 21, the holder raises the tubular body 21 or the inserter pushes the ultrasonic diagnostic apparatus 2 toward the lower opening 21d. As a result, the distal end portion 2a of the ultrasonic diagnostic apparatus 2 (that is, the sensor 12a portion of the probe 12) soon enters the inner hole 31a of the bracket body 31 and hits the probe cover body 23 further. In the tubular body 21, the distance between the lower end 21b and the separation portion 26, that is, the distance between the probe cover body 23 and the separation portion 26 is the predetermined distance L, as described above. Therefore, by advancing the ultrasonic diagnostic apparatus 2 until its tip touches the probe cover body 23, the entire ultrasonic diagnostic apparatus 2 can be housed in the body portion 25 of the cylindrical body 21. FIG.

After storing, the gripper grasps the main body portion 25 and the separating portion 24 with separate hands, and separates the separating portion 24 from the main portion 25 along the perforations of the separating portion 26 (see FIG. 5). At this time, the holder separates the separation portion 24 from the main body portion 25 without touching the contaminated site that the ultrasonic diagnostic apparatus 2 would have touched. After disconnecting, the holder pushes the ultrasonic diagnostic apparatus 2 downward over the body portion 25 . By doing so, the holder can push the ultrasonic diagnostic apparatus 2 without touching it directly.

Further, when pushed, the probe cover body 23 expands according to the shape of the distal end of the ultrasonic diagnostic apparatus 2 , and the distal end portion 2 a of the ultrasonic diagnostic apparatus 2 protrudes from the bracket main body 31 . If the pressing is continued further, the pair of fitting protrusions 11d, 11d will eventually come into contact with the corresponding locking pieces 33, 33, and the locking pieces 33, 33 will be pushed outward by the corresponding fitting protrusions 11d, 11d. When the ultrasonic diagnostic apparatus 2 is moved to a predetermined position by continuing to press after that, the pair of fitting protrusions 11d, 11d are fitted into the locking holes 33a, 33a. As a result, the pair of locking pieces 33, 33 are elastically restored, and the ultrasonic diagnostic apparatus 2 is attached to the bracket main body 31 (see FIG. 2).

After mounting, in order to seal the ultrasonic diagnostic apparatus 2 in the ultrasonic diagnostic apparatus cover 3, the folded upper portion 25a is attached to the remaining portion of the main body portion 25 using an adhesive tape, hook-and-loop fastener, or the like. As a result, the ultrasonic diagnostic apparatus 2 is housed and sealed in the ultrasonic diagnostic apparatus cover 3 (see FIG. 6). In this manner, the cover-equipped ultrasonic diagnostic apparatus 1 is ready for use by covering the ultrasonic diagnostic apparatus 2 with the ultrasonic diagnostic apparatus cover 3, and the puncture operation is performed. A puncture operation using the covered ultrasonic diagnostic apparatus 1 will be described below.

First, the user presses the probe 12 of the ultrasonic diagnostic apparatus 2 against the body surface via the probe cover body 23 . Then, ultrasonic waves are oscillated from the probe 12 and the cross section of the test site (near the desired puncture site) is displayed on the monitor 13 . At this time, depending on the state of acoustic coupling, a liquid gel or the like may be applied to the body surface to further improve the acoustic coupling. When the cross section of the site to be examined is displayed on the monitor 13, the user scans the ultrasonic diagnostic apparatus 2 while looking at the monitor 13 to search for the position of the blood vessel. After confirming the position of the blood vessel, the needle 41 of the needle assembly is inserted into the guide hole 32b of the guide portion 32, and the needle tip 41a of the needle 41 is punctured into the blood vessel. The guide hole 32b is formed so that the needle 41 inserted and punctured therein corresponds to the image displayed on the monitor 13. As shown in FIG. For example, the inserted needle 41 and the needle 41 displayed on the monitor 13 overlap when viewed from the front. Thereby, the position of the needle tip 41a after puncturing can be confirmed on the monitor 13 in advance (that is, before puncturing).

When it is confirmed that the needle tip 41a has punctured the blood vessel, the needle 41 is pulled out from the guide hole 32b through the extraction port 32c in order to remove the ultrasonic diagnostic apparatus 2 from the needle 41. FIG. That is, the needle 41 is pulled out from the guide hole 32b through the take-out opening 32c by tilting the ultrasonic diagnostic apparatus 2 rearward so as to separate it from the needle 41. As shown in FIG. By doing so, the needle 41 can be left at that position, and subsequent treatment (for example, treatment such as dialysis, liquid injection, and blood sampling) can be performed.

In the cover-equipped ultrasonic diagnostic apparatus 1 configured in this manner, the ultrasonic diagnostic apparatus 2 that has not been sterilized is inserted through the upper opening 21c. When the open end is touched, the outer surface of the upper opening 21c and the open end may be contaminated. In this state, a person other than the inserter, for example, a grasper, etc., touches the contaminated site of the upper opening 21c, the contaminated site of the upper opening 21c touches the outer surface of the main body portion 25, or another surgical instrument is contaminated. There is a possibility that the contaminated part may spread to various places by touching the part. In this regard, in the covered ultrasonic diagnostic apparatus 1 , the separating portion 24 including the upper opening 21 c that is the contaminated portion can be separated from the main body portion 25 in the cylindrical body 21 . As a result, it is possible to prevent the gripper and the user from accidentally touching the contaminated site on the outer surface of the upper opening 21c and spreading the contamination to other sites.

Further, in the ultrasonic diagnostic apparatus cover 3 , the ultrasonic diagnostic apparatus 2 is housed in the tubular body 21 , so the inner surface of the tubular body 21 may be contaminated by touching the ultrasonic diagnostic apparatus 2 . If the ultrasonic diagnostic apparatus cover 3 does not have the inner cylinder portion 27, the inner surface around the separation portion 26 is also invariably contaminated by touching the ultrasonic diagnostic apparatus 2. FIG. Therefore, when the separation portion 24 is separated from the main body portion 25, the vicinity of the separation portion 26, which is the inner surface of the main body portion 25, may be contaminated by a person holding it or the like. On the other hand, in the ultrasonic diagnostic apparatus cover 3 , the inner cylinder portion 27 is arranged to extend beyond the separation portion 26 to reach the body portion 25 and cover the separation portion 26 . Therefore, when the ultrasonic diagnostic apparatus 2 is inserted into the cylindrical body 21, the ultrasonic diagnostic apparatus 2 does not touch the inner surface of the main body portion 25 and the vicinity of the separation portion 26, and the vicinity thereof is contaminated. can be prevented. In addition, the inner cylinder portion 27, whose inner surface may be contaminated during insertion, is separated from the main body portion 25 together with the separation portion 24. As shown in FIG. Therefore, it is possible to prevent contamination of the touched part when the gripper touches the inner cylinder part 27 after the separation. Therefore, when the gripper touches the upper portion 25a to fold the upper portion 25a of the main body portion 25 after cutting, it is possible to suppress contamination of the touched portion.

The inner cylindrical portion 27 having such a function can be formed by simply folding back the opening side portion 20a of the bag-like member 20 inward. Therefore, it is easy to manufacture the ultrasonic diagnostic apparatus cover 3 having the above functions. In addition, the separation portion 26 formed to separate the separation portion 24 and the main body portion 25 is also formed with perforations, which simplifies the production and facilitates the separation work. The inner cylinder portion 27 does not necessarily have to be formed by folding the opening side portion 20a of the bag-like member 20 inward, but is constructed by attaching another member forming the inner cylinder portion 27 to the separation portion 24. may The separation portion 26 is also not necessarily limited to perforations, and the separation portion 24 may be easily separated from the body portion 25 by providing a notch or by changing the material, thickness, or the like. Further, the separation portion 24 and the main body portion 25 may be fixed by engaging the hard members, or the separation portion 24 and the main body portion 25 may be separated by releasing the engagement. The separating portion 24 and the main body portion 25 may not be formed of the same member but may be separate members.

[About other embodiments]
In the ultrasonic diagnostic apparatus cover 3 of the present embodiment, the probe cover body 23 is attached to the cylindrical body 21 via the bracket 22 with the guide, but it is not necessarily via the bracket 22 with the guide. That is, the probe cover body 23 may be directly provided on the tubular body 21 . Also, the shape of the guide-equipped bracket 22 is not limited to that described above, and may be cylindrical. Further, the ultrasonic diagnostic apparatus cover 3 does not necessarily have to be composed of the tubular body 21 and the probe cover body 23, and may be composed of one bag-like member made of the same material as the tubular body 21. good.

Moreover, the covered ultrasonic diagnostic apparatus 1 is not necessarily used for puncture work, and may be used only for displaying a cross-section of a test site on the monitor 13 . In this case, the guide-equipped bracket 22 does not necessarily have the guide portion 32 , and the bracket body 31 may be the only member constituting the guide-equipped bracket 22 .

The entire probe cover 23 is composed of an elastomer gel that provides good acoustic coupling between the test site and the probe 12, that is, styrene, urethane, and silicone elastomer gels. does not need to be configured to For example, at least a portion of the probe cover 23 located between the site to be examined and the probe 12 may be made of the above-described elastomer gel.

The cylindrical body 21 is fixed along the outer peripheral surface of the bracket main body 31, but it is not always necessary to adopt such a fixing method. It may be fixed along the inner peripheral surface of the bracket main body 31 . Moreover, the fixing method is not limited to fixation, and for example, the lower opening 21d of the tubular body 21 and the probe cover body 23 may be sandwiched between the two brackets 34 and 35 and fixed.

In addition, in the ultrasonic diagnostic apparatus cover 3 of the present embodiment, the cylindrical body 21 is constructed by folding back the opening side portion 28a of the cylindrical member 28, but it is not always necessary to be constructed in this way. no. For example, the tubular body of another embodiment may be configured as follows. That is, in the tubular body of another embodiment, the separation portion 24 and the inner tubular portion 27 are configured by separate members. The inner cylindrical portion 27 is formed by rolling a substantially rectangular sheet into a substantially cylindrical shape, and is arranged in the separating portion 24 in this state. Further, the inner cylindrical portion 27 is arranged so that the outer peripheral surface of the upper opening portion thereof faces the inner peripheral surface of the upper opening portion of the separation portion 24, and they are welded to each other.

In the cylindrical body configured in this manner, sealant layers are formed on the outer peripheral surface of the upper opening portion of the inner cylindrical portion 27 and the inner peripheral surface of the upper opening portion of the separation portion 24, respectively, and heat is applied to them. As a result, the upper opening portion of the inner cylinder portion 27 and the upper opening portion of the separation portion 24 are welded together. When the separation part 24 is welded, it is flatly folded so as to close the upper opening part, and in this state, heat is applied to the upper opening part and the vicinity thereof from the outside while sandwiching the upper opening part. By doing so, the upper opening portion of the inner cylindrical portion 27 and the upper opening portion of the separating portion 24 are welded together, and a cylindrical body similar to the cylindrical body 21 of the first embodiment is constructed.

As described above, the cylindrical body of the other embodiment does not require the procedure of folding back the one opening side portion 28a, and is therefore more suitable for manufacturing by machine than the cylindrical body 21 of the first embodiment. Further, in the cylindrical body of the other embodiment, the sealant layer is not formed on the inner peripheral surface of the upper opening portion of the inner cylindrical portion 27, and the inner peripheral surfaces are welded to each other even if heat is applied. There is no Therefore, no new work is required to form the upper opening of the tubular body into which the ultrasonic diagnostic apparatus 2 can be inserted, and the tubular body can be easily formed.

It should be noted that the outer cylinder portion composed of the separation portion 24 and the main body portion 25 is not limited to being formed in a cylindrical shape in advance, and may be configured as follows. That is, it may be constructed by overlapping two sheet-like members and welding both side edge portions in a predetermined direction, or by folding one sheet and welding the overlapped portions. may be configured. The same applies to the tubular member 28 of the first embodiment. Also, the inner cylindrical portion 27 is not limited to a single sheet rolled into a cylindrical shape, and may be formed in a cylindrical shape in advance. In addition, in the cylindrical body of another embodiment, the portions where the inner cylinder portion 27 is welded to the separation portion 24 are not necessarily limited to the upper opening, and the inner peripheral surface of the separation portion 24 and the inner cylinder portion 27 are not necessarily limited to the upper opening. Any part may be used as long as it is the outer peripheral surface of the . Further, for example, the structure may be such that the upper opening of the inner cylinder portion is folded outward and the separation portion 24 is welded there.
