[0031] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] In the existing foaming test equipment for diagnosing patent foramen ovale, the touch screen is prone to heat during operation, resulting in a relatively high temperature of the internal electronic components, which is likely to damage the equipment or reduce its service life, and the heat is conducted to the outside, which is not conducive to the doctor's inspection and operation.

[0033] Embodiment 1

[0034] To solve the above problems, this embodiment provides an ultrasonic contrast injection device, as Figure 2As shown in the figure, the present device includes: a main unit and a display screen. The main unit is provided with a foaming injection part. By touching the display screen, it is possible to control the start or stop of the foaming injection module to produce a contrast agent, and control the start or stop of injecting the contrast agent into the human body; the display screen is detachably connected to the main unit, for example, magnetically or by snap connection. For example, a third magnetic part is provided on the display screen, and a fourth magnetic part is provided on the main unit, and the third magnetic part is correspondingly connected to the fourth magnetic part.

[0035] As Figure 3 and 4 shown, the display screen includes a connected upper housing and a lower housing. Preferably, the upper housing and the lower housing are connected by snap connection. As Figure 9 shown, the snap-in amount is 0.6 mm. This snap-in amount can not only ensure the firm connection of the upper and lower shells, but also facilitate disassembly.

[0036] Among them, as Figure 5 shown, a battery, a control chip, a screen body, a heat sink, and a blower are installed on the lower housing. The control chip is a PCBA. As Figure 6 shown, one end of the heat sink is located above the control chip and can cover the components on the column control chip, and there is a gap between the two. The gap is filled with thermal conductive silicone. Specifically, the heat sink can be fixed to the lower housing by screws.

[0037] The present device uses thermal conductive silicone to bond the heat sink to the components, rather than directly contacting the heat sink with the components, which solves the problems existing in the prior art. For example, the heights of the components are different, and the required shape of the heat sink is complex, which is not conducive to processing. Using thermal conductive silicone for connection simplifies the shape of the heat sink and improves the processing efficiency; secondly, it improves the fit and connection tightness between the heat sink and the components, avoiding the problem of poor contact caused by processing dimensional errors; it can also provide buffering to avoid poor contact between the heat sink and the components caused by vibration and dropping.

[0038] As Figure 7 shown, the blower is installed at a position close to the control chip below the heat sink. Optionally, the blower is provided with an air inlet close to the heat sink and an air outlet on the side close to the side wall of the lower housing. A through hole is provided at the corresponding position of the lower housing and the air outlet, so as to be able to absorb the heat of the heat sink and discharge it outside the lower housing. A dust-proof net is provided inside the through hole to prevent large particles of foreign matter or dust from entering the outside, and it does not affect the ventilation effect while preventing dust. Preferably, the lower housing is equipped with a silicone plug (not shown in the figure). When the program needs to be burned, the silicone plug is opened, and when it is not needed, the silicone plug is closed to prevent water and dust.

[0039] As Figure 8As shown, the upper housing is provided with a button, which is electrically connected to the control chip. Preferably, it is a cantilever button, which is fixed to the upper housing by hot melting. This assembly method is firm and simple, and can effectively control costs. A button control board is also provided below the button, and the button control board is electrically connected to the control chip. A screen foam is provided on the upper housing. The screen foam is located above the screen body, with a thickness of 1.0 mm. The gap between the screen body and the upper housing is 0.8 mm. The screen foam has a compression amount of 0.2 mm, which can prevent dust from entering the interior. At the same time, it also has a buffering effect. When dropped or impacted, it can buffer part of the force, making the screen body not easily broken. The upper housing is also provided with a light guide column. An LED lamp board is provided below the light guide column and is electrically connected to the control chip. The LED light can be evenly led out to the upper housing. There is a rib between the two light guide columns to avoid mutual influence between the lights.

[0040] As Figure 2 and 3 shown, a detachable blowing handle is installed on the main body, preferably in a magnetic connection manner. For example, a first magnetic part is provided on the blowing handle, and a second magnetic part is provided on the main body. The first magnetic part is correspondingly connected to the second magnetic part. During the foaming test, the real-time air pressure value can be detected through the blowing handle, replacing the Valsalva maneuver. The operation is simple and the accuracy is high.

[0041] The control chip of this device is connected to the heat sink through thermal conductive silicone. Its thermal conductivity is relatively high, improving the heat dissipation efficiency. A blower is provided under the heat sink, which can inhale the heat generated by the heat sink and the control chip and discharge it outside the lower housing, enabling rapid heat dissipation, thus greatly reducing the temperature during the use of the display screen and solving the problems caused by the heat generation of the display screen.

[0042] Embodiment 2

[0043] As Figure 1 shown, in order to enhance the adaptability of this device, a detachable base is provided below the main body, which can support the main body and change its height. Wheels are provided below the base to facilitate the movement of this device.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
