Therefore, the ultrasonic diagnostic apparatus of Patent Literature 1 is entirely covered by a cover at the time of puncturing, and this cover prevents blood and the like from adhering to the ultrasonic diagnostic apparatus itself, and also adheres to the ultrasonic diagnostic apparatus. It also prevents splashed blood and the like from scattering.

JP 2018-011766 A

  In the cover of Patent Literature 1, as described above, the ultrasonic diagnostic apparatus is inserted from the opening of the cover main body. At that time, the ultrasonic diagnostic apparatus touches the outer surface of the opening, so that the outer surface of the opening is May be contaminated. In addition, a person who closes the opening unexpectedly touches the outer peripheral surface of the opening with the glove, and further touches a portion other than the opening with the contaminated glove, so that the contaminated portion is enlarged. Therefore, it is preferable to insert the ultrasonic diagnostic apparatus into the cover so that the ultrasonic diagnostic apparatus does not touch the outer peripheral surface of the opening, but it is not easy to insert the ultrasonic diagnostic apparatus without touching it.

  Thus, the present invention provides a method for contaminating an outer surface of an opening from a contaminated site on the outer surface of the opening to a portion other than the opening even if the outer surface of the opening is contaminated when the ultrasonic diagnostic apparatus is inserted into the cover body. It is an object of the present invention to provide a cover for an ultrasonic diagnostic apparatus capable of suppressing the operation and an ultrasonic diagnostic apparatus with a cover including the same.

  A cover for an ultrasonic diagnostic apparatus of the present invention is provided on the casing, a probe having a sensor disposed at one end of the casing in a predetermined direction and having a sensor for receiving ultrasonic waves reflected at a portion to be measured, and A monitor for displaying an image corresponding to the ultrasonic wave received by the sensor, and a cover for the ultrasonic diagnostic apparatus which is placed so as to cover the entire ultrasonic diagnostic apparatus, the ultrasonic diagnostic apparatus being insertable. And a main body portion capable of accommodating the entire ultrasonic diagnostic apparatus, wherein the separation portion is configured to be separable from the main body portion.

  According to the present invention, even if the outer surface of the opening is contaminated when the ultrasonic diagnostic apparatus is inserted, the separation portion is separated from the main body portion to separate from the contaminated site on the outer surface of the opening to a portion other than the opening. It is possible to suppress the contamination from spreading. For example, the spread of contamination can be suppressed by the role sharing between the gripper and the inserter as described below. That is, the grasper grasps the main body portion so as to open the opening, and the inserter inserts the ultrasonic diagnostic apparatus through the opening. After insertion, the inserter can detach the separation portion including the opening from the main body portion, so that the opening having the contaminated site on the outer surface can be removed from the cover. Thus, it is possible to prevent the contamination from spreading from the contamination site to a portion other than the opening.

  ADVANTAGE OF THE INVENTION According to this invention, even when the outer surface of an opening is contaminated, it can suppress that contamination expands from a contaminated site to a part other than an opening.

The concept of the direction used in the following description is used for convenience in the description, and does not limit the direction of the configuration of the invention to the direction. The ultrasonic diagnostic apparatus 1 with a cover described below is merely an embodiment of the present invention. Therefore, the present invention is not limited to the embodiment, and can be added, deleted, or changed without departing from the spirit of the invention.

<Ultrasonic diagnostic device with cover>
The ultrasonic diagnostic apparatus 1 with a cover shown in FIG. 1 is used when puncturing a needle or the like while visualizing a blood vessel or the like under the skin, and is used, for example, when placing a catheter in a blood vessel in dialysis treatment. The ultrasonic diagnostic apparatus 1 with a cover having such a function includes an ultrasonic diagnostic apparatus 2 and a cover 3 for the ultrasonic diagnostic apparatus, and the ultrasonic diagnostic apparatus 2 is covered with the cover 3 for the ultrasonic diagnostic apparatus. used. Hereinafter, an example of the configuration of the ultrasonic diagnostic apparatus 2 and the cover 3 for the ultrasonic diagnostic apparatus will be described.

<Ultrasonic diagnostic equipment>
The ultrasonic diagnostic apparatus 2 oscillates an ultrasonic wave at a site to be inspected (that is, subcutaneous tissue) while being applied to the body surface, and receives an ultrasonic wave (that is, a reflected wave) reflected at the site to be inspected. . In addition, the ultrasonic diagnostic apparatus 2 performs image processing based on the received reflected waves to project a cross section of a test site. The ultrasonic diagnostic apparatus 2 having such a function includes a casing 11, a probe 12, and a monitor 13. The casing 11 is made of, for example, a synthetic resin such as polycarbonate, ABS (acrylonitrile butadiene styrene) resin, SAS (silicon acrylonitrile styrene), and polypropylene, and is a box having a substantially rectangular shape and a flat cross section in a front view. . A distal end portion 11a, which is one end of the casing 11 in a predetermined direction, is formed in a trapezoidal shape tapering toward the distal end, and a probe 12 is disposed on the distal end 11b of the casing 11. That is, the ultrasonic diagnostic apparatus 2 has the probe 12 at the tip 2a. A monitor 13 is arranged on the front surface 11c of the middle part of the casing 11, and an image is displayed on the monitor 13. Hereinafter, the probe 12 and the monitor 13 will be described in more detail.

  The probe 12 is configured to transmit and receive an ultrasonic wave, and has a sensor 12a. The sensor 12a includes a vibrator such as a piezoelectric element and an acoustic lens. The sensor 12a configured as described above is mounted so as to be embedded in the front end portion 11b of the casing 11, and the lower end surface of the sensor 12a is substantially flush with the front end surface of the casing 11. The sensor 12a arranged as described above is connected to a control device (not shown) accommodated in the casing 11, and oscillates ultrasonic waves in response to a command 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 the image data. The monitor 13 has an image created based on the reflected wave received by the sensor 12a, for example, A cross section of the inspection site is shown.

  The ultrasonic diagnostic apparatus 2 configured as described above applies the probe 12 to the body surface of the test site, and oscillates ultrasonic waves from the sensor 12a in that state. The oscillated ultrasonic wave is reflected at the test site, and the sensor 12a receives the reflected wave reflected at the test site and outputs a signal corresponding to the received ultrasonic wave to the control device. The control device performs image processing based on the signal, and causes the monitor 13 to project a cross section of the test site. This allows the user to scan the ultrasonic diagnostic apparatus 2 while viewing both the region to be examined and the cross-sectional image.

  In the ultrasonic diagnostic apparatus 2 having such a function, blood or the like may adhere at the time of puncturing or the like, and it is preferable to sterilize each time the puncturing is performed. However, in the ultrasonic diagnostic apparatus 2, the monitor 13 is not waterproofed, and if the ultrasonic diagnostic apparatus 2 is sterilized, a problem may occur. Therefore, it is not easy to perform a sterilization process on 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 performing a sterilization process. Hereinafter, the ultrasonic diagnostic apparatus cover 3 will be described.

<Cover for ultrasonic diagnostic equipment>
The ultrasonic diagnostic apparatus cover 3 covers the entire ultrasonic diagnostic apparatus 2 so that blood or the like does not adhere to the ultrasonic diagnostic apparatus 2 or to prevent blood or the like adhering thereto from scattering. Is covered. The ultrasonic diagnostic apparatus cover 3 having such a function is formed in a bag shape including a tubular body 21, a bracket 22 with a guide, and a probe cover body 23 (see FIG. 2). The tubular 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 subjected to a sterilization process. As shown in FIGS. 1 and 2, the tubular body 21 made of such a material is formed in a substantially rectangular shape that is long in the vertical direction when viewed from the front. The external shape of the cylindrical body 21 is similar to the ultrasonic diagnostic apparatus 2 when viewed from the front, and the lower end portion 21a is formed in a trapezoidal shape tapering toward the lower end 21b. Further, the tubular body 21 is formed in a tubular shape so that the ultrasonic diagnostic apparatus 2 can be accommodated therein. The cylindrical body 21 thus configured has openings 21c and 21d at both upper and lower ends thereof, and the openings 21c and 21d are configured as follows.

  When opened in the front-rear direction, the upper opening 21c, which is the first opening, can be made substantially flat in plan view when viewed from above, and when opened, the outer shape is smaller than the outer shape of the ultrasonic diagnostic apparatus 2. It is formed large. The upper opening 21c allows the ultrasonic diagnostic apparatus 2 to be inserted therefrom. Further, the cylindrical body 21 has a separation portion 24 and a main body portion 25, and the upper end portion including the upper opening 21 c forms the separation portion 24, and the remaining portion forms the main body portion 25. ing. Further, the separation portion 24 is configured to be separable (that is, separable) from the remaining main body portion 25, and the cylindrical body 21 is separated from the separation portion 24 and the main body portion 25 so as to be separated. A separation site 26 is formed between them. The separation portion 26 is formed over the entire circumference of the cylindrical body 21 in the circumferential direction, 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 disposed at a predetermined distance L above the lower end 21b of the tubular body 21. The predetermined distance L is the sum of the vertical length of the ultrasonic diagnostic apparatus 2 and the thickness in the front-rear direction. That is all.

  The tubular body 21 is made up of a tubular member 28 having both ends open, and is formed as follows. That is, the tubular body 21 is formed by folding one opening side portion 28a of the tubular member 28 inward over the entire circumference, and the upper end after the folding forms the upper opening 21c. Further, the one opening side portion 28a is arranged inside the separation portion 24 by folding back, and forms the inner cylindrical portion 27. The inner cylinder portion 27 thus formed extends from the upper opening 21c to the main body portion 25 beyond the separation portion 26, and covers the separation portion 26 from the inside over the entire circumference in the circumferential direction. The lower opening 21d is configured as follows with respect to the upper opening 21c configured as described above.

  That is, the lower opening 21d, which is the second opening, has the lower end portion 21a formed in an inverted trapezoidal shape as described above, and has a smaller diameter than the upper opening 21c. Therefore, after inserting the ultrasonic diagnostic apparatus 2 from the upper opening 21c of the cylindrical body 21, the distal end 2a of the ultrasonic diagnostic apparatus 2 is naturally guided to the lower opening 21d. 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, and the lower opening 21d is formed. , The tip 2a of the ultrasonic diagnostic apparatus 2 can be projected. The lower opening 21d having such a shape is provided with a bracket 22 with a guide for attaching a probe cover body 23 described in detail later.

  The bracket with guide 22 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 described later, for example, a synthetic resin such as polycarbonate, ABS (acrylonitrile butadiene styrene) resin, SAS (silicon acrylonitrile styrene), and polypropylene. The bracket main body 31 made of such a material is substantially plate-shaped as shown in FIGS. 1 and 2 in a front view, and is formed in a horizontally long, flat and annular shape as shown in FIG. 3 in a plan view. . In addition, in FIG. 3, the guide part 32 is not illustrated for convenience of explanation.

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

  The pair of locking pieces 33, 33 are plate-shaped members, and extend obliquely upward so as to extend outward from the upper surface of the bracket main body 31. The pair of locking pieces 33, 33 arranged in this manner are arranged left and right so that their main surfaces face each other, and the tip side portion 11a of the casing 11 is inserted between the main surfaces. It has become. A locking hole 33a is formed in each of the main surfaces of the pair of locking pieces 33,33. Further, a pair of fitting projections 11d, 11d (see FIG. 1) are formed on the side surface of the casing 11 so as to correspond to the respective locking holes 33a. Therefore, when the ultrasonic diagnostic apparatus 2 is inserted into the bracket main body 31 to a predetermined position, each of the pair of fitting protrusions 11d, 11d is fitted into the corresponding locking hole 33a, and the fitting is performed. The ultrasonic diagnostic apparatus 2 is locked and held by the bracket body 31.

  The shape of the outer peripheral surface of the bracket main body 31 configured as described above is formed to be substantially the same as the shape of the lower opening 21d. That is, the bracket 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 body 31 over the entire circumference. The target is welded. Thus, the bracket body 31 is provided in the lower opening 21 d of the tubular body 21, and the probe cover body 23 is provided in the tubular body 21 via the bracket body 31.

  The probe cover body 23 is configured to have good acoustic coupling and expand and contract, and is made of, for example, a styrene-based, urethane-based, or silicone-based elastomer gel (a styrene-based elastomer gel in the present embodiment). The probe cover body 23 made of such a material has a substantially flat plate shape, and is formed in a substantially rectangular shape which is horizontally long in plan view. More specifically, the probe cover body 23 is similar to the shape of the inner hole 31a of the bracket main body 31 in a plan view, and is formed slightly larger than the inner hole 31a. The probe cover body 23 thus configured is fixed to the bracket main body 31, and the bracket main body 31 is configured as follows to fix the probe cover body 23.

  That is, as shown in FIG. 4, the bracket main body 31 includes two members, namely, a first bracket portion 34 and a second bracket portion 35. Each of the first bracket portion 34 and the second bracket portion 35 is a flat and annular shape that is horizontally long in the left-right direction in plan view, and is formed in substantially the same shape as each other. The first bracket portion 34 is provided with a pair of locking pieces 33, 33 on its upper surface, and is placed on the second bracket portion 35 so as to overlap with each other and is engaged with each other. Further, an outer peripheral edge of the probe cover body 23 is interposed between the two bracket sections 34 and 35, and the probe cover body 23 extends over the entire outer peripheral edge in the circumferential direction. 35. As described above, the probe cover body 23 is fixed to the bracket main body 31 by being sandwiched by the two bracket portions 34 and 35, and is provided on the tubular body 21 via the bracket main body 31.

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

  The guide portion 32 guides the needle 41 when puncturing the needle 41 of a needle device such as an indwelling needle and determines the puncturing direction, and is formed in a substantially block shape. The guide portion 32 having such a shape is integrally attached to the front surface of the second bracket portion 35. The guide portion 32 does not necessarily need to be provided on the second bracket portion 35, and may be provided on the front surface of the first bracket portion 34. The guide portion 32 is attached to the bracket main body 31 such 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. Further, a guide hole 32b is formed in the guide portion 32 and penetrates in the vertical direction. 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 therein, and the needle tip 41a is protruded from below the guide hole 32b so that the puncture site can be punctured. An outlet 32c is formed in the front end surface 32a of the guide portion 32, and the outlet 32c is formed so that the needle 41 inserted into the guide hole 32b can be tilted forward and fall out.

<Installation work and puncture work>
In the following, a description will be given of a mounting operation for covering the ultrasonic diagnostic apparatus 2 with the ultrasonic diagnostic apparatus 2 in order to use the ultrasonic diagnostic apparatus 2. The mounting operation is performed by two persons, an inserter who inserts the ultrasonic diagnostic apparatus 2 and a gripper who grips the ultrasonic diagnostic apparatus cover 3. The ultrasonic diagnostic device cover 3 is put in a bag such as a sterile pack (not shown) so as to maintain a sterile condition, and the ultrasonic diagnostic device cover 3 is taken out of the sterile pack by a grasper at the time of use. After the removal, the grasper opens the upper opening 21c of the cylindrical body 21 of the ultrasonic diagnostic device cover 3 back and forth, and then the inserter inserts the ultrasonic diagnostic device 2 from the distal end portion 2a into the upper opening 21c. I do.

  Thereafter, in order to fit the entire ultrasonic diagnostic apparatus 2 in the cylindrical body 21, the grasper stands the cylindrical body 21 or the inserter pushes the ultrasonic diagnostic apparatus 2 toward the lower opening 21d. Then, the distal end portion 2 a of the ultrasonic diagnostic apparatus 2 (that is, the portion of the sensor 12 a of the probe 12) enters the inner hole 31 a of the bracket main body 31 and finally hits the probe cover body 23. As described above, the distance between the lower end 21b and the separation portion 26 of the cylindrical body 21, that is, the distance between the probe cover body 23 and the separation portion 26 is the predetermined distance L. Therefore, the entire ultrasonic diagnostic apparatus 2 can be accommodated in the main body portion 25 of the tubular body 21 by advancing the ultrasonic diagnostic apparatus 2 until the distal end thereof contacts the probe cover body 23.

  After the storage, the gripper grasps the main body portion 25 and the separation portion 24 with different hands, and separates the separation portion 24 from the main body portion 25 along the perforation of the separation portion 26 (see FIG. 5). At this time, the grasper separates the separation part 24 from the main body part 25 so as not to touch the contaminated site that the ultrasonic diagnostic apparatus 2 would have touched. After the separation, the grasper pushes the ultrasonic diagnostic apparatus 2 downward through the main body portion 25. By doing so, the grasper can push the ultrasonic diagnostic apparatus 2 without directly touching it.

  When pushed in, the probe cover body 23 extends in accordance with the shape of the distal end of the ultrasonic diagnostic apparatus 2, and the distal end 2 a of the ultrasonic diagnostic apparatus 2 projects from the bracket body 31. When the pushing is further continued, the pair of fitting projections 11d, 11d eventually hit the corresponding locking pieces 33, 33, and the locking pieces 33, 33 are pushed outward by the corresponding fitting projections 11d, 11d. After that, when the ultrasonic diagnostic apparatus 2 is moved to a predetermined position by continuing to push, the pair of fitting projections 11d, 11d fit into the locking holes 33a, 33a. Then, the pair of locking pieces 33, 33 is elastically restored, and the ultrasonic diagnostic apparatus 2 is engaged with the bracket main body 31 and mounted (see FIG. 2).

  After the mounting, the folded upper portion 25a is attached to the remaining portion of the main body portion 25 using an adhesive tape or a hook-and-loop fastener in order to seal the ultrasonic diagnostic apparatus 2 in the ultrasonic diagnostic apparatus cover 3. Thus, the ultrasonic diagnostic apparatus 2 is housed in the ultrasonic diagnostic apparatus cover 3 and hermetically sealed (see FIG. 6). As described above, in the ultrasonic diagnostic apparatus 1 with the cover, the ultrasonic diagnostic apparatus 2 can be used by putting the ultrasonic diagnostic apparatus cover 3 on the ultrasonic diagnostic apparatus 2, and the puncturing operation is performed. Hereinafter, a puncture operation using the ultrasonic diagnostic apparatus 1 with a cover will be described.

  First, the user presses the probe 12 of the ultrasonic diagnostic apparatus 2 on the body surface via the probe cover body 23. Then, ultrasonic waves are oscillated from the probe 12, and a cross section of the portion to be inspected (around a desired puncture site) is displayed on the monitor 13. At this time, a liquid gel or the like may be applied to the body surface according to the state of the acoustic coupling to further improve the acoustic coupling. When the cross section of the test site 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 a blood vessel. When the position of the blood vessel is confirmed, 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 as to correspond to the needle 41 inserted and punctured therein and the image projected on the monitor 13. For example, the inserted needle 41 and the needle 41 projected on the monitor 13 are overlapped in a front view. This allows the monitor 13 to confirm the position of the needle tip 41a after puncturing in advance (that is, before puncturing).

  Then, when it is confirmed that the needle tip 41a has been punctured into the blood vessel, the needle 41 is pulled out from the guide hole 32b through the outlet 32c in order to remove the ultrasonic diagnostic apparatus 2 from the needle 41. That is, the needle 41 is pulled out from the guide hole 32b through the outlet 32c by tilting the ultrasonic diagnostic apparatus 2 rearward so as to separate from the needle 41. By doing so, the needle 41 can be placed at that position, and subsequent treatment (for example, treatment such as dialysis, liquid injection, and blood collection) can be performed.

  In the ultrasonic diagnostic apparatus 1 with the cover configured as described above, since the ultrasonic diagnostic apparatus 2 that has not been sterilized is inserted through the upper opening 21c, the ultrasonic diagnostic apparatus 2 can be connected to the outer surface of the upper opening 21c or the like. When touching the opening end, the outer surface and the opening end of the upper opening 21c may be contaminated. In this state, a person other than the inserter, for example, a gripper, 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 treatment instrument becomes contaminated. Touching the site may spread the contaminated site to various locations. In this regard, in the ultrasonic diagnostic apparatus with cover 1, the separation portion 24 including the upper opening 21 c which is a contaminated site in the tubular body 21 can be separated from the main body portion 25. Accordingly, it is possible to prevent the gripper and the user from unexpectedly touching the contaminated site on the outer surface of the upper opening 21c and spreading the contamination to other sites.

  In addition, since the ultrasonic diagnostic apparatus 2 is housed in the cylindrical body 21 in the ultrasonic diagnostic apparatus cover 3, the inner surface of the cylindrical body 21 may be contaminated by touching the ultrasonic diagnostic apparatus 2. When the cover 3 for an ultrasonic diagnostic apparatus does not have the inner cylindrical portion 27, the inner surface around the separation site 26 is also contaminated by touching the ultrasonic diagnostic apparatus 2 without exception. Therefore, when the separation portion 24 is separated from the main body portion 25, the gripper or the like may be contaminated by touching the inner surface of the main body portion 25 near the separation portion 26. On the other hand, in the cover 3 for an ultrasonic diagnostic apparatus, the inner cylindrical portion 27 is disposed so as to reach the main body portion 25 beyond the separation portion 26 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 is contaminated. Can be prevented. Further, the inner cylindrical portion 27 that may be contaminated on the inner surface during insertion is separated from the main body portion 25 together with the separating portion 24. Therefore, it is possible to prevent the gripper from touching the inner cylindrical portion 27 after the separation, thereby preventing the touched portion from being contaminated. Therefore, when the gripper touches the upper portion 25a to turn the upper portion 25a of the main body portion 25 after the separation, it is possible to suppress contamination of the touched portion.

  The inner cylindrical portion 27 having such a function can be formed only by turning 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 function. In addition, the separation portion 26 formed to separate the separation portion 24 from the main body portion 25 is also formed with perforations, so that its manufacture is simple and the separation operation can be facilitated. The inner cylinder portion 27 does not necessarily need to be formed by folding the opening side portion 20a of the bag-shaped member 20 inward, and is configured by attaching another member forming the inner cylinder portion 27 to the separation portion 24. You may. The separation portion 26 is not necessarily limited to the perforation. The separation portion 24 may be easily separated from the main body portion 25 by providing a notch or changing a material, a thickness, or the like. Further, the fixing of the separation portion 24 and the main body portion 25 may be realized by engagement of the hard members, and the separation portion 24 and the main body portion 25 may be separated by releasing the engagement. The separation part 24 and the main body part 25 may be separate members without being formed by the same member.

[Other Embodiments]
In the cover 3 for an ultrasonic diagnostic apparatus of the present embodiment, the probe cover body 23 is attached to the tubular body 21 via the bracket 22 with a guide, but the probe cover body 23 does not necessarily need to be provided via the bracket 22 with a guide. That is, the probe cover 23 may be provided directly on the tubular body 21. Further, the shape of the bracket with guide 22 is not limited to that described above, and may be cylindrical. Furthermore, the cover 3 for an ultrasonic diagnostic apparatus does not necessarily need to be constituted by the tubular body 21 and the probe cover body 23, and may be constituted by one bag-shaped member made of the same material as the tubular body 21. Good.

  In addition, the ultrasonic diagnostic apparatus 1 with a cover is not necessarily limited to the one used for puncturing work, and may be used when only displaying a cross section of a test site on the monitor 13. In this case, the guide-equipped bracket 22 does not necessarily need to have the guide part 32, and the member constituting the guide-equipped bracket 22 may be only the bracket body 31.

  The probe cover body 23 is entirely made of an elastomer gel having good acoustic coupling between the test site and the probe 12, that is, a styrene-based, urethane-based, and silicone-based elastomer gel. It does not need to be configured. For example, at least a portion of the probe cover body 23 located between the test site and the probe 12 may be formed of the above-described elastomer gel.

  The tubular body 21 is fixed along the outer peripheral surface of the bracket main body 31, but it is not always necessary to use such a fixing method. The bracket may be fixed along the inner peripheral surface of the bracket body 31. Further, the fixing method is not limited to the fixing method. For example, the lower opening 21d of the tubular body 21 may be fixed between the two bracket portions 34 and 35 together with the probe cover body 23.

  Further, in the cover 3 for an ultrasonic diagnostic apparatus of the present embodiment, the tubular body 21 is formed by folding back one opening side portion 28a of the tubular member 28, but it is not always necessary to be configured in this manner. There is no. For example, the cylindrical body of another embodiment may be configured as follows. That is, in the cylindrical body of another embodiment, the separation portion 24 and the inner cylindrical portion 27 are formed by different members. The inner cylindrical portion 27 is formed by rolling a substantially rectangular sheet into a substantially cylindrical shape, and is disposed in the separating portion 24 in that state. Further, the inner cylindrical portion 27 is arranged such that the outer peripheral surface of the upper opening portion thereof is opposed to 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 as described above, a sealant layer is formed on each of the outer peripheral surface of the upper opening of the inner cylindrical portion 27 and the inner peripheral surface of the upper opening of the separation portion 24, and heat is applied thereto. Thus, the upper opening of the inner cylinder portion 27 and the upper opening of the separation portion 24 are welded. When welding, the separating portion 24 is flatly folded so as to close the upper opening portion, and in this state, heat is applied thereto while sandwiching the upper opening portion and the vicinity thereof from the outside. By doing so, the upper opening portion of the inner cylindrical portion 27 and the upper opening portion of the separation portion 24 are welded, and a cylindrical body similar to the cylindrical body 21 of the first embodiment is configured.

  As described above, the tubular body of the other embodiment does not require a procedure of turning back one opening side portion 28a, and is therefore more suitable for manufacturing by a machine than the tubular body 21 of the first embodiment. Further, in the tubular body of the other embodiment, no sealant layer is 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 when heat is applied. There is no. Therefore, a new operation is not 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.

  In addition, the outer cylinder part comprised by the separation part 24 and the main-body part 25 is not limited to what was previously formed in cylindrical shape, and may be comprised as follows. That is, two sheet-shaped members may be overlapped with each other and their side edges in a predetermined direction may be welded to each other, or one sheet may be folded back and the overlapped portions welded. You may comprise. The same applies to the cylindrical member 28 of the first embodiment. In addition, the inner cylindrical portion 27 is not limited to a single sheet obtained by rounding a single sheet into a cylindrical shape, but may be a member formed in a cylindrical shape in advance. Further, in the cylindrical body of the other embodiment, the portions where the inner cylinder portions 27 are welded to the separation portions 24 are not necessarily limited to the upper openings, but the inner peripheral surface of the separation portions 24 and the inner cylinder portions 27. Any portion may be used as long as it is the outer peripheral surface of. Further, for example, a structure in which the upper opening of the inner cylinder portion is turned outward and the separation portion 24 is welded thereto.
