In addition, the exhaust gas (hot air) can be prevented from directly hitting the subject.

FIG. 5 is a front perspective view of the main body 1 as viewed from the front. The main body 1 is provided with a probe connecting portion 4 for connecting an ultrasonic probe on the side (side surface) of the housing 50. A battery (battery pack) 8 is accommodated in a battery accommodating portion 51 provided in the lower front part of the housing 50.

The first opening 15 is provided at a position facing the battery exhaust port 19 in a state where the battery 8 is housed in the battery housing 51. The first opening 15 is provided at the interface of a universal joint (connection part) 30 that connects the main body 1 and the display part 3. Further, in the case of the battery housing portion 51, the first opening portion 15 may be provided at an interface of a portion other than the universal joint (connection portion) 30 (for example, an upper portion or a rear portion of the battery housing portion 51).

Next, the flow of air (intake and exhaust) of the portable ultrasonic diagnostic apparatus 100 will be described.
As shown in FIG. 6, the air is sucked from the battery inlet 9, passes through a part of the battery 8, and is exhausted from the battery exhaust 19. The air passes through a part of the battery 8 to cool the battery 8.

As shown in FIG. 7, the air exhausted from the battery exhaust port 19 is sucked from the first opening 15 and guided to the inside of the main body 1 (first flow path). The air sucked from the third opening 11 is exhausted from the fourth opening 12 after being guided to the inside of the main body 1 (second flow path). Note that the first flow path may be provided along the surface of the battery 8. Thereby, the cooling efficiency of the battery 8 is improved.

As shown in FIG. 8, the air guided from the first opening 15 to the inside of the main body 1 (first flow path) is exhausted from the second opening 10 provided at the rear of the housing 50. The Air is sucked from the side opening 13, guided to the inside of the main body 1 (first flow path), and then exhausted from the second opening 10 provided behind the housing 50.

Next, the flow path of air that is sucked and exhausted will be described. FIG. 9 is a rear perspective view of the schematic internal structure of the main body 1 as viewed from the rear. The housing 50 includes a housing rear portion 22, a housing upper portion 23, and a housing lower portion 24. The housing rear part 22 includes a second opening 10. The housing upper part 23 includes a third opening 11 and a fourth opening 12. The housing 50 includes the substrate 16 therein. The substrate 16 has a lower surface portion (first flat surface portion) 53 and an upper surface portion (second flat surface portion) 54. The substrate 16 is mounted with various circuits that realize the functions of the portable ultrasonic diagnostic apparatus 100.

For example, the lower surface portion (first flat surface portion) 53 of the substrate 16 is mounted with a power supply unit, a power supply controller, and the like that are connected to the battery 8 and an external power supply to generate power for each unit. Further, the upper surface portion (second flat surface portion) 54 of the substrate 16 includes a signal control unit that controls an ultrasonic transmission / reception signal of the ultrasonic probe, and a calculation unit that calculates an ultrasonic image based on the ultrasonic reception signal. In addition, an I / O unit responsible for input / output control of the interface 14 is installed. Since FIG. 9 is a schematic diagram, components mounted on the board 16 are omitted, but many other circuit components (for example, CPU, resistors, capacitors, various digital ICs, LSIs, analog ICs) are omitted. Etc.) is mounted on the substrate 16 and is mounted with high density. FIG. 9 shows the CPU 29 as a component that generates a large amount of heat. Although not shown, the CPU 29 and the like are also mounted on the lower surface portion (first flat surface portion) 53 of the substrate 16.

The portable ultrasonic diagnostic apparatus 100 includes a flow path (first flow path) 55 that guides intake air from the first opening 15 in order to cool the substrate 16. The flow path (first flow path) 55 is configured by a lower surface portion (first flat surface portion) 53 of the substrate 16 and guides intake air from the first opening 15 along the planar direction of the substrate 16. The second opening 10 exhausts the intake air that has passed through the flow path (first flow path) 55. According to this configuration, since the flow path is configured by the lower surface portion 53 of the substrate 16, a portion that was a dead space can be used as the flow path.

The portable ultrasonic diagnostic apparatus 100 includes a first fan 18 that generates an intake airflow from the first opening 15, and a second fan 17 that generates an intake airflow from the third opening 11. Is provided. According to this configuration, the first fan 18 generates an air flow of intake air, so that the flow of air passing through the first flow path 55 can be promoted, and the second fan 17 generates an air flow of intake air. By doing so, the flow of air passing through the inside of the main body 1 can be promoted, and the cooling effect of the portable ultrasonic diagnostic apparatus 100 can be enhanced.

In a state where the battery 8 is accommodated in the battery accommodating portion 51, the battery intake port 9 is located in front of the casing 50, and the second opening 10 is located in the rear of the casing 50. According to this configuration, since air linearly passes from the battery inlet 9 to the second opening 10, the cooling effect of the portable ultrasonic diagnostic device 100 without air staying inside the housing Can be increased.

FIG. 10 is a central sectional view of the main body 1 along the front-rear direction. As shown in FIG. 10, the air sucked from the battery intake port 9 passes through a part of the battery 8 and is exhausted from the battery exhaust port 19. In this case, the air passing through a part of the battery 8 may cool the battery 8. In addition, the battery air inlet 9 and the battery air outlet 19 are provided at the front upper part and the upper part of the battery 8, respectively, and are arranged at orthogonal positions. However, the battery air outlet 19 is provided at the rear of the battery 8 and The intake air from the port 9 may pass through the inside of the battery 8 and be exhausted from the battery exhaust port 19. Further, the flow path for the air to pass through the battery 8 may be formed in a wave shape in order to enhance the cooling effect of the battery 8.

The air exhausted from the battery exhaust port 19 is sucked from the first opening 15 provided in the battery housing 51. The first opening 15 may be provided in the connection portion 30 (FIG. 5) in consideration of size and space restrictions. Further, the position of the first opening 15 may be determined in accordance with the position of the battery exhaust port 19. For example, when the battery exhaust port 19 is provided behind the battery 8, the first opening 15 may be provided behind the battery housing part 51. A plurality of first openings 15 may be provided.

The air sucked from the first opening 15 is guided to the inside of the main body 1 and is a pre-stage flow path 55a of the flow path (first flow path) 55 formed between the battery housing portion 51 and the substrate 16. And then passes through the rear flow path 55b. The air passing through the flow path (first flow path) 55 mainly cools the lower surface portion (first flat surface portion) 53 side of the substrate 16. As shown in FIG. 10, the front channel 55a is configured to have a smaller space than the rear channel 55b. As a result, the flow rate of air passing through the front-stage flow channel 55a is faster than the flow rate of air passing through the rear-stage flow channel 55b, and the cooling effect of the substrate 16 is enhanced.

The air that has passed through the flow path (first flow path) 55 is exhausted from the second opening 10.

The air sucked from the third opening 11 provided on the upper surface of the housing 50 is guided to the inside of the main body 1 (second flow path 56). In other words, the third opening 11 provided on the upper surface of the housing 50 sucks air in order to cool the upper surface portion (second flat surface portion) 54 of the substrate 16. The flow path (second flow path) 56 is a flow path (second flow path) 56, which is constituted by the upper surface portion (second flat surface portion) 54 of the substrate 16, and intake air from the third opening 11 Lead. The flow path (second flow path) 56 guides the intake air from the third opening 11 along the planar direction of the substrate 16. The fourth opening 12 provided at the rear of the housing 50 exhausts the intake air that has passed through the flow path (second flow path) 56. According to this configuration, air is guided from the battery exhaust port 19 to the inside, and by securing a plurality of flow paths, both surfaces (upper and lower surfaces) of the substrate can be cooled at the same time, greatly restricting size and space. In portable ultrasonic diagnostic apparatus 100 with high substrate density, the cooling efficiency of the apparatus can be increased.

As shown in FIG. 10, the battery air inlet 9 and the second opening 10 face each other in the front-rear direction of the housing 50 in a state where the battery 8 is housed in the battery housing 51. The battery inlet 9 is located in front of the housing 50, and the second opening 10 is located in the rear of the housing 50.

As a result, air passes linearly from the battery inlet 9 to the second opening 10 (from the front to the rear of the main body 1), so that the air is not retained inside the housing 50 and the device is cooled. The effect can be enhanced.

In order to facilitate the insertion of the battery 8 into the main body 1, the battery 8 is inserted into the battery housing 51 from the front of the main body 1. Therefore, considering the size and space restrictions, conventionally, the battery 8 has blocked the air flow path from the front of the main body 1. In addition, a side opening 13 is provided on the side of the main body 1 for intake, but space is divided for the probe connection 4 and various interfaces 14, making it difficult to secure sufficient ventilation holes. Thus, sufficient cooling could not be performed with only the side openings 13. Further, since the intake air from the side opening 13 passes non-linearly from the side of the main body 1 to the rear (from the side opening 13 to the second opening 10), the air enters the housing 50. It stayed.

On the other hand, in the present embodiment, by providing the battery 8 with the battery intake port 9 and the battery exhaust port 19, a flow path is secured inside the battery 8, and air passes linearly from the front to the rear of the main body 1. A flow path can be secured. As a result, the cooling function of the portable ultrasonic diagnostic apparatus 100 that satisfies the size and space restrictions can be enhanced, and the battery 8 can also be cooled. Further, since the battery inlet 9 is hidden behind the operation unit 2 when the portable ultrasonic diagnostic apparatus 100 is used, it is possible to prevent foreign matter from being mixed in and to ensure a stable inflow of air.

Further, in the present embodiment, the first flow path 55 and the second flow path 56 are provided inside the main body 1, and the air passing through the first flow path 55 is the first flat portion 53 of the substrate 16. Since the air passing through the second flow path 56 cools the second flat surface portion 54 of the substrate 16, both surfaces (upper and lower surfaces) of the substrate 16 can be simultaneously cooled. The cooling function of the ultrasonic diagnostic apparatus 100 can be enhanced. The first channel 55 is formed in the lower part of the substrate 16 (between the substrate 16 and the housing lower part 24), so that the portion that was a dead space can be used as the channel. In particular, the front flow path 55a is formed between the battery housing part 51 and the substrate 16, so that the portion that was a dead space can be used as the flow path. Further, since the front-stage flow channel 55a is formed narrower than the rear-stage flow channel 55b, the speed of air passing through the front-stage flow channel 55a can be increased, and the cooling function of the portable ultrasonic diagnostic apparatus 100 is enhanced. be able to.
