Like the bracket main body 21, both the first bracket 25 and the second bracket 26 have a horizontally long flat shape and an annular shape. The first bracket 25 and the second bracket 26 are provided with a plurality of engaging portions 25a and engaged portions 26a that engage with each other along the circumferential direction. Therefore, the first bracket 25 and the second bracket 26 are combined in the vertical direction, and the engaging portion 25a and the engaged portion 26a are engaged with each other to be integrated, thereby forming the bracket main body 21. The first bracket 25 on the upper side is provided with the above-mentioned pair of engaging pieces 23, and the second bracket 26 on the lower side is provided with a guide attachment part 27 to which the needle guide 22 is attached (see FIG. 4). See B).

The needle guide 22 guides the needle 28 of a needle assembly such as an indwelling needle (see the two-dot chain line in FIG. 4A) when puncturing the subcutaneous tissue and defines the puncturing direction. The needle guide 22 has a block shape when viewed from the side, and a guide groove 29 for supporting the needle 28 is formed on the front surface. Such a needle guide 22 is attached to a guide attachment portion 27 of the second bracket 26.

The guide attachment portion 27 has a guide engagement portion 30 that protrudes downward from the front lower surface of the second bracket 26 . On the other hand, the needle guide 22 has a back shape that follows the front and lower surfaces of the second bracket 26, and the lower portion thereof forms a guide engaged portion 31 that engages with the guide engaging portion 30 described above. ing. That is, when the needle guide 22 and the guide attachment part 27 are brought closer to each other from the front and rear directions from the state shown in FIG. 4(B), the guide engagement part 30 is engaged with the guide as shown in FIG. The portion 31 is engaged, and the needle guide 22 is attached to the guide attachment portion 27. This defines the direction in which the guide groove 29 extends with respect to the bracket 20 (the direction in which the needle 28 is guided). Note that the guide attachment portion 27 is provided at the center position of the second bracket 26 in the left-right direction.

[Cover for ultrasound diagnostic equipment]
The ultrasonic diagnostic apparatus cover 3 covers the entire ultrasonic diagnostic apparatus 2 to prevent blood or the like from adhering to the ultrasonic diagnostic apparatus 2 during treatment.

Furthermore, in the upper part of the main body cover 40, the front film 40a extends higher than the rear film 40b, and an adhesive layer 44 is provided on the rear surface of the upper part of this extended portion 43.

[How to accommodate ultrasound diagnostic equipment]
The ultrasonic diagnostic apparatus 2 is inserted into the main body cover 40 through the opening 42 in the upper part thereof, with the lower part 11a of the casing 11 facing the bottom part 41. Then, the lower part 11a of the casing 11 is pressed against the inner surface of the bottom part 41 of the main body cover 40, and in this state, the upper extension part 43 of the main body cover 40 is bent rearward and pressed against the outer surface of the rear film 40b to adhere it and open the opening. 42 is sealed. Thereby, the ultrasonic diagnostic apparatus 2 is accommodated within the main body cover 40 with the probe 12 in close contact with the bottom 41 of the main body cover 40.

Next, the bracket 20 is attached to the ultrasonic diagnostic apparatus 2 housed in the main body cover 40. That is, as already explained, the lower part 11a of the casing 11 is inserted into the bracket main body 21 to a predetermined position, and the left and right projections 11e of the casing 11 are engaged with the left and right engaging pieces 23 of the bracket main body 21. Thereby, the bracket 20 is attached to the ultrasonic diagnostic apparatus 2 while being housed in the main body cover 40, as shown in FIGS. 2(A) and 2(B). At this time, a main body cover 40 is interposed between the ultrasonic diagnostic apparatus 2 and the bracket 20. More specifically, the main body cover 40 is held between the engaging piece (engaging portion) 23 of the bracket 20 and the protruding portion (engaged portion) 11e of the casing 11. Hereinafter, the portion of the main body cover 40 that is held between the engagement piece 23 and the projection 11e will be referred to as a first holding portion 51.

[Reinforcement structure of main body cover]
In the ultrasonic diagnostic apparatus cover 3 according to the present embodiment, a reinforcing structure 50 is provided in a predetermined target area 51A including the first clamping portion 51 of the main body cover 40. This prevents the main body cover 40 from being perforated due to the first clamping portion 51 being clamped between the ultrasound diagnostic apparatus 2 and the bracket 20. Note that the above target area 51A is a part of the main body cover 40 that includes the first clamping portion 51 (a partial area of the entire area).

As shown in FIG. 5(B), the reinforcing structure 50 in the target area 51A has at least two layers in the thickness direction, and specifically includes a first layer 55 and a second layer 56. Among these, the first layer 55 is located relatively inside and occupies the entire area of the main body cover 40, and the second layer 56 is located outside the first layer 55 and occupies the target area 51A which is a partial area. ing. In addition, the main body cover 40 may include an additional layer in addition to the first layer 55 and the second layer 56, and the additional layer is located inside the first layer 55 and between the first layer 55 and the second layer 56. It may be provided at any position between the second layer 56 or outside the second layer 56. Additionally, an additional layer may include an adhesive layer that adheres adjacent layers.

The materials of the first layer 55 and the second layer 56 are not limited to a specific material, and at least they are more difficult to be punctured when sandwiched between the engagement piece 23 and the protrusion 11e than the first layer 55. It is sufficient if the second layer 56 is better. For example, it is preferable that the second layer 56 has a higher hardness than the first layer 55. In this case, the method for measuring hardness is not particularly limited, but for example, a test method based on "scratching hardness (pencil method)" specified in JIS K5600 can be adopted.

As an example, the first layer 55 may be made of at least one of polyethylene (PE), polyurethane (PU), polypropylene (PP), polyvinyl chloride (PVC), and polyvinyl alcohol (EVOH). I can do it. Further, as the material of the second layer 56, at least one of polyethylene terephthalate (PET), nylon (NY), polycarbonate (PC), polyacrylonitrile butylene styrene (ABS), and polystyrene (PS) is adopted. can do. Further, as a combination of the first layer 55 and the second layer 56, for example, the first layer 55 may be made of polypropylene (PP), and the second layer 56 may be made of polyethylene terephthalate (PET).

Note that the method for manufacturing such a reinforcing structure 50 is not particularly limited, and any known method for manufacturing a multilayer structure film can be used as appropriate. For example, melted resin, which is the raw material for the second layer 56, is applied to the first layer 55 that forms the base material and then pressure bonded, or the second layer 56 is applied to the surface of the first layer 55 with an adhesive layer in between. It may also be manufactured by lamination, such as by thermocompression bonding.

As described above, in the ultrasonic diagnostic apparatus cover 3 according to the present embodiment, the first clamping portion 51 clamped between the casing 11 and the bracket 20 has the reinforcing structure 50. For this reason, it is possible to suppress the occurrence of perforation in the first clamping portion 51 due to attachment of the bracket 20 (ensure high perforation resistance). Furthermore, since the reinforcing structure 50 is applied only to the target area 51A, high flexibility can be ensured in other parts of the main body cover 40, which improves workability when housing the ultrasonic diagnostic apparatus 2 in the main body cover 40. You can improve your performance. Further, in the reinforcing structure 50, the inner first layer 55 has a low hardness, and the outer second layer 56 has a high hardness. This ensures high puncture resistance when the engaging piece 23 of the bracket 20 rubs against the outer surface of the main body cover 40 when the bracket 20 is attached to the casing 11, while also ensuring that the ultrasonic diagnostic apparatus 2 accommodated Surface scratches can be suppressed.

(Embodiment 2)
Other configurations of the ultrasonic diagnostic apparatus with a cover will be described with reference to FIGS. 6(A), (B), and FIG. 7. The ultrasonic diagnostic apparatus 1A with a cover according to the second embodiment has the same configuration as that described in the first embodiment regarding the ultrasonic diagnostic apparatus 2 and the bracket 20. On the other hand, the manner in which the ultrasonic diagnostic apparatus 1 is accommodated in the ultrasonic diagnostic apparatus cover and the configuration of the main body cover that constitutes the ultrasonic diagnostic apparatus cover are different from those described in the first embodiment. These differences will be explained in detail below.

The covered ultrasonic diagnostic apparatus 1A shown in FIGS. 6(A) and 6(B) includes an ultrasonic diagnostic apparatus 2, an ultrasonic diagnostic apparatus cover 3A placed over the ultrasonic diagnostic apparatus 2, and a bracket 20. The cover 3A includes a main body cover 40A. In the second embodiment, when the ultrasonic diagnostic apparatus 2 is housed in the ultrasonic diagnostic apparatus cover 3A, the bracket 20 is first attached to the ultrasonic diagnostic apparatus 2. That is, the bracket 20 is attached to the ultrasonic diagnostic apparatus 2 without interposing the main body cover 40A therebetween. At this time, the needle guide 22 is separated from the bracket 20.

Next, the ultrasonic diagnostic apparatus 2 with the bracket 20 attached is housed in the main body cover 40A. Specifically, the lower part 11a of the casing 11 is inserted toward the bottom 41 of the main body cover 40A, the lower part 11a is pressed against the inner surface of the bottom 41, and in this state, the opening 42 at the upper part of the main body cover 40A is sealed. Then, the needle guide 22 is attached to the guide attachment portion 27 of the bracket 20. At this time, the main body cover 40A is interposed between the guide attachment portion 27 and the needle guide 22. More specifically, the main body cover 40A is held between the guide engaging portion 30 of the guide attachment portion 27 and the guide engaged portion 31 of the needle guide 22. Hereinafter, the portion of the main body cover 40A that is held between the guide engaging portion 30 and the guide engaged portion 31 will be referred to as a second holding portion 52.

As shown in FIG. 7, in the main body cover 40A according to the second embodiment, a reinforcing structure 50 is provided in a predetermined target area 52A including the second clamping portion 52. Note that, as this reinforcing structure 50, a structure similar to that described in Embodiment 1 can be adopted. Further, the above-mentioned target area 52A is a part of the main body cover 40A that includes the second clamping portion 52 (partial area of the entire area). Furthermore, as can be seen from the above description, the main body cover 40A is not held between the engaging piece 23 of the bracket 20 and the projection 11e of the casing 11, and does not have the first holding part 51. Therefore, no reinforcing structure is provided in the region corresponding to the first clamping portion 51 described in the first embodiment.

According to the configuration described above, in the ultrasonic diagnostic device cover 3A according to the present embodiment, the second clamping portion 52 clamped between the guide attachment portion 27 and the needle guide 22 has the reinforcing structure 50. . Therefore, it is possible to prevent perforation from occurring in the second clamping portion 52 due to attachment of the needle guide 22 (ensure high perforation resistance). In addition, since the reinforcing structure 50 is applied only to the target area 52A, high flexibility can be ensured in other parts of the main body cover 40A, which improves workability when housing the ultrasound diagnostic apparatus 2 in the main body cover 40A. You can improve your performance. Note that from the viewpoint of production, there may be a reinforcing portion other than the predetermined area facing the clamping portion.

In this embodiment, the needle guide 22 is attached to the bracket 20, but the needle guide 22 is attached directly to the ultrasonic diagnostic apparatus 2 (specifically, the casing 11) (not via the bracket). You may adopt the structure which attaches. In this case, in the main body cover 40A of the ultrasonic diagnostic apparatus cover 3A, the part held between the needle guide 22 and the ultrasonic diagnostic apparatus 2 is defined as a second holding part 52, and as described above, this second holding part 52 What is necessary is just to apply the reinforcement structure 50 to 52 A of predetermined|prescribed target areas containing.

(Modification 1)
By the way, the areas on the main body cover where the reinforcing structure 50 is applied are not limited to those illustrated in the first and second embodiments (target areas 51A and 52A). In a main body cover 40B according to modification example 1 shown in FIG. 8, a reinforcing structure 50 is provided over the entire area. That is, in the case of this main body cover 40B, the entire area constitutes a target area 53A, and a reinforcing structure 50 including a first layer 55 and a second layer 56 is applied to this target area 53A.

Such a main body cover 40B can be used in place of the main body cover 40 because the target area 53A includes the first clamping portion 51 of the first embodiment. Similarly, the main body cover 40B can be used in place of the main body cover 40A since the target area 53A includes the second clamping portion 52 of the second embodiment. Such a main body cover 40B is excellent in productivity while preventing perforation.

Note that other variations may be adopted for the area where the reinforcing structure 50 is provided in the main body cover. For example, one partial region including both the first clamping portion 51 and the second clamping portion 52 may be set as a target region, and the reinforcing structure 50 may be applied to this target region. Such a main body cover can also be used in place of either the main body cover 40 or the main body cover 40A, similarly to the above-described main body cover 40B.

(Embodiment 3)
Other configurations of the ultrasonic diagnostic apparatus with a cover will be described with reference to FIGS. 9(A), (B), and FIG. 10. The ultrasonic diagnostic apparatus 1C with a cover according to the third embodiment has the same configuration as that described in the first embodiment regarding the ultrasonic diagnostic apparatus 2 and the bracket 20. On the other hand, this covered ultrasonic diagnostic apparatus 1C includes, in addition to the bracket 20, a cover set 3C for an ultrasonic diagnostic apparatus that includes a main body cover 40C and a cover film 70 having a configuration different from that described above.

The main body cover 40C has a cylindrical shape made of film, has an opening 60 at one end connected to the bracket 20, and covers the other end of the casing 11 with the bracket 20 attached to the casing 11. Further, the engagement piece 23 of the bracket 20 is located inside the main body cover 40C, and the guide attachment portion 27 of the bracket 20 is located outside the main body cover 40C. Further, a cover film 70 is connected to the bracket 20 so as to close the opening 21a. This will be explained in more detail below.

As described above, the bracket 20 is configured by vertically combining the first bracket 25 on the upper side (the other end side) and the second bracket 26 on the lower side (one end side) and integrating them. There is. Engagement pieces 23 are provided on the left and right upper surfaces of the first bracket 25, and a guide attachment portion 27 is provided protruding from the front lower surface of the second bracket 26 (see FIG. 4(B)).

The circumferential length of the opening 60 at one end (lower side) of the cylindrical main body cover 40C is approximately the same as the circumferential length of the outer peripheral surface of the first bracket 25. The inner peripheral surface of the opening 60 of the main body cover 40C is connected to the outer peripheral surface of the first bracket 25. In this embodiment, both are liquid-tightly connected over the entire circumference by thermal welding. Note that the other end side (upper side) of the main body cover 40C can adopt a configuration including an extension portion 43 and an adhesive layer 44 similarly to the previously described main body cover 40, but other configurations may also be adopted. .

On the other hand, a cover film 70 is sandwiched and supported between the first bracket 25 and the second bracket 26 which are divided into upper and lower parts. That is, as shown in FIG. 10, a first protrusion 25b is formed on the lower surface of the first bracket 25, extending over the entire circumference of the first bracket 25 and protruding downward. Further, a second protruding portion 26b is formed on the upper surface of the second bracket 26 and extends over the entire circumference of the second bracket 26 and protrudes upward. In the example of FIG. 10, two first protrusions 25b and two second protrusions 26b are formed, and the first protrusions 25b and second protrusions 26b are arranged vertically with respect to each other. They are located opposite each other.

The cover film 70 has approximately the same outer diameter as the bracket 20 when viewed from above, and the peripheral edge portion of the cover film 70 is held between the first protrusion 25b and the second protrusion 26b from above and below. There is. Thereby, the cover film 70 closes the opening 21a of the bracket 60 in a liquid-tight manner.

In this way, the ultrasonic diagnostic apparatus cover set 3C according to the present embodiment has a configuration in which the bracket 20, the main body cover 40C, and the cover film 70 are integrated before the ultrasonic diagnostic apparatus 2 is housed. It becomes. Furthermore, the engaging piece 23 is located inside the main body cover 40C, and the guide attachment portion 27 is located outside the main body cover 40C.

When the ultrasonic diagnostic device 2 is housed in this ultrasonic diagnostic device cover set 3C, the ultrasonic diagnostic device 2 is inserted into the main body cover 40C from the upper opening 42 of the main body cover 40C, with the lower part 11a of the casing 11 first. I'm going to put it in. Then, the bracket 20 is attached to the ultrasonic diagnostic apparatus 2 by engaging the projection 11e of the casing 11 with the engagement piece 23 located inside the main body cover 40C. Then, the upper opening 42 of the main body cover 40C is sealed by folding back the extended portion 43 and gluing it. Note that since the guide attachment portion 27 is always located outside the main body cover 40C, the needle guide 22 can be attached either before or after the ultrasonic diagnostic apparatus 2 is attached.

According to the configuration described above, in the ultrasonic diagnostic apparatus cover set 3C according to the present embodiment, the main body cover 40C is not clamped when the ultrasonic diagnostic apparatus 2 is accommodated. Therefore, the main body cover 40C does not need to have the reinforcing structure 50 in preparation for perforation due to clamping as described above. Therefore, for the main body cover 40C according to the present embodiment, the material can be selected with priority given to other purposes rather than puncture resistance. Other purposes include, for example, stacking properties related to workability when housing the ultrasound diagnostic device 2 (the lower the stacking properties, the better the workability), and transparency related to the visibility of the monitor 13 during treatment (transparency). Materials can be selected by taking into consideration factors such as (the higher the resistance, the better the visibility).

Further, the material of the cover film 70 can be selected on the basis of a material that has high adhesion to the probe 12 and a material that is highly transparent to the ultrasonic waves emitted from the probe 12. Note that the same material may be used as long as the specifications required for the main body cover 40C and the specifications required for the cover film 70 are within the same range, and in that case, the main body cover 40C and the cover film 70 may be It is also possible to have an integrated configuration.

(Modification 2)
In the case of the ultrasonic diagnostic apparatus cover set 3C according to the third embodiment, the main body cover 40C is not held between the engagement piece 23 and the casing 11, as described above. On the other hand, since the engaging piece 23 of the bracket 20 is located inside the main body cover 40C, when removing the bracket 20 from the ultrasonic diagnostic apparatus 2 after use, the engaging piece 23 must be operated through the main body cover 40C. Must be.

Therefore, in the ultrasonic diagnostic apparatus cover sets 3D and 3E according to Modification 2, a cutting auxiliary part is provided on the main body cover so that the main body cover can be cut off after use and the engagement piece 23 can be directly operated. The main body cover including this cutting auxiliary part will be described in detail below.

The main body cover 40D constituting the ultrasonic diagnostic apparatus cover set 3D shown in FIG. There is. More specifically, the cutting auxiliary part 80 is provided in a region sandwiched between the left and right engaging pieces 23 and on the front side where the guide attachment part 22 is located.

This cutting auxiliary part 80 has a broken line-shaped notch 81 formed in the main body cover 40D and a seal 82 that covers this notch 81. For example, the cut 81 has a shape along a line segment forming a rectangular U-shape that is open on one side. Therefore, a small piece 81a surrounded by the notch 81 is formed in the main body cover 40D. Note that the shape of the notch 81 is not limited to this, and other shapes such as a curved U-shape that is open on one side or a V-shape that is open on one side may be adopted.

The seal 82 is a sheet piece having a larger area than the small piece 81a, and has an adhesive layer provided on one main surface. The seal 82 is attached to the outer surface of the main body cover 40D so as to cover the entire notch 81. Note that the seal 82 shown in FIG. 11(A) has a grip portion 82a at its end (end on the other side) that partially does not have an adhesive layer on the main surface.

Such a cutting auxiliary part 80 grasps the grip part 82a of the seal 82 and pulls it to one side, thereby pulling the small piece 81a glued to the seal 82, cutting the notch 81, and cutting the small piece. 81a is separated from the main body cover 40D. When the seal 82 is further pulled, a cut portion from the notch 81 is formed extending in the direction in which the seal 82 is pulled. Then, when the seal 82 is pulled and the cut point passes one side of the main body cover 40D, the engagement piece 23 on one side located inside the main body cover 40D is exposed. Therefore, at this time, the bracket 20 can be removed from the ultrasonic diagnostic apparatus 2 by directly operating the engagement piece 23 (without using the main body cover 40D). Furthermore, if the seal 82 is further pulled and rotated, the other side of the main body cover 40D can also be cut, and the engagement piece 23 on the other side can also be exposed, so this engagement piece 23 can also be operated directly. I can do it.

Although FIG. 11A shows an example in which only one cutting auxiliary part 80 is provided on the main body cover 40D, the present invention is not limited to this, and two or more (plural) cutting auxiliary parts 80 may be provided on the main body cover 40D. Good too. For example, two cutting auxiliary parts 80 are provided on the front surface of the main body cover 40D, and one cutting auxiliary part 80 is operated to one side to expose the engagement piece 23 on one side, and the other cutting auxiliary part The portion 80 may be operated to the other side to expose the engagement piece 23 on the other side. Furthermore, although FIG. 11(A) shows an example in which the cutting assisting part 80 is provided on the front surface of the main body cover 40D, the cutting assisting part 80 may be provided on the rear or side surface of the main body cover 40D. .

Further, when the cutting auxiliary part 80 is provided on the front surface of the main body cover 40D and near the guide mounting part 27 (particularly between the left and right engaging pieces 23 and near the upper part of the guide mounting part 27), By being guided by the guide attachment part 27 and the needle guide 22 attached thereto during scanning by the ultrasonic diagnostic apparatus 2, it is possible to prevent the seal 82 from getting caught on the patient's clothes or the like. Furthermore, the seal 82 may be attached to the inner surface of the main body cover 40D so as to cover the notch 81. In this case, when cutting the main body cover 40D, it is sufficient to grasp and pull the small piece 81a formed by the notch 81.

A main body cover 40E constituting the ultrasonic diagnostic apparatus cover set 3E shown in FIG. 11(B) is provided with a cutting auxiliary portion 86 formed of a notch 85 at its side end. More specifically, the main body cover 40E has a connecting portion 86 at the other end where the front film 40a and the rear film 40b are welded together. This connecting portion 87 extends in the vertical direction along the side of the main body cover 40E, and has a predetermined width dimension in the left-right direction. A notch 85 is formed in this connecting portion 87 at a position near the engaging piece 23 . The shape of the notch 85 is not particularly limited, but may be, for example, semicircular as shown in FIG. 11(B), or may be wedge-shaped.

When cutting such a main body cover 40E, the upper and lower parts are grasped through the notch 85 of the cutting auxiliary part 86, respectively, and operated in opposite directions in the front and back directions, or in opposite directions in the up and down directions. Thereby, the main body cover 40E can be cut from the notch 85, and the engagement piece 23 on the other side can be exposed. Further, by operating the gripping portion more widely, the main body cover 40E can be cut to a larger extent, and the engagement piece 23 on one side can also be exposed. Therefore, the bracket 20 can be removed from the ultrasonic diagnostic apparatus 2 by directly operating the left and right engaging pieces 23.

Although FIG. 11B shows an example in which only one cutting auxiliary part 86 is provided on the main body cover 40E, the invention is not limited to this, and two or more (plural) cutting auxiliary parts 86 may be provided on the main body cover 40E. Good too. For example, the connecting portions 87 may be formed on both the left and right sides of the main body cover 40E, and the notches 85 may be formed in the left and right connecting portions 87, so that each of the connecting portions 87 may be used as the cutting auxiliary portion 86.
