Detailed Implementation

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0029] The existing foaming test equipment used to diagnose patent foramen ovale is prone to overheating during operation, which can lead to high temperatures in the internal electronic components, potentially damaging the equipment or reducing its lifespan. Furthermore, the heat can be conducted to the outside, making the examination difficult for doctors.

[0030] Example 1

[0031] To address the aforementioned problems, this embodiment provides an ultrasound contrast injection device, as shown in Figure 2. The device includes a main unit and a display screen. The main unit has a foaming injection section. By touching the display screen, the device can control the start or stop of the foaming injection module to produce the contrast agent, and control the start or stop of injecting the contrast agent into the human body. The display screen and the main unit are detachably connected, for example, by magnetic connection or snap-fit. For example, the display screen has a third magnetic section, and the main unit has a fourth magnetic section, with the third magnetic section and the fourth magnetic section correspondingly connected.

[0032] As shown in Figures 3 and 4, the display screen includes an upper housing and a lower housing connected together. Preferably, the upper housing and the lower housing are connected by a snap-fit ​​method, as shown in Figure 9, with a snap-fit ​​amount of 0.6mm. This snap-fit ​​amount can ensure the firmness of the connection between the upper and lower housings and facilitate disassembly.

[0033] As shown in Figure 5, the lower housing is equipped with a battery, a control chip, a screen body, a heat-conducting sheet, and a blower. The control chip is a PCBA. As shown in Figure 6, one end of the heat-conducting sheet is located above the control chip and can cover the components on the control chip. There is a gap between the two, and the gap is filled with thermally conductive silicone. Specifically, the heat-conducting sheet can be fixed to the lower housing with screws.

[0034] This device uses thermally conductive silicone to bond the heat-conducting pad to the components, rather than having the heat-conducting pad directly contact the components. This solves the problems existing in the prior art. For example, components of varying heights require complex shapes of heat-conducting pads, which are not conducive to processing. Using thermally conductive silicone simplifies the shape of the heat-conducting pad and improves processing efficiency. Secondly, it improves the adhesion and tightness of the connection between the heat-conducting pad and the components, avoiding poor contact problems caused by processing dimensional errors. It can also provide cushioning to prevent poor contact between the heat-conducting pad and the components caused by vibration and drops.

[0035] As shown in Figure 7, the blower is installed below the heat-conducting plate near the control chip. Optionally, the blower has an air inlet near the heat-conducting plate and an air outlet near the side wall of the lower housing. The lower housing has through holes corresponding to the air outlet positions, allowing heat from the heat-conducting plate to be absorbed and discharged outside the lower housing. A dustproof mesh is installed inside the through holes to prevent large particles or dust from entering, ensuring ventilation without affecting the dustproof effect. Preferably, the lower housing is fitted with a silicone plug (not shown in the figure). The silicone plug is opened when programming is required and closed when not in use, for waterproofing and dustproofing.

[0036] As shown in Figure 8, the upper housing is equipped with buttons, which are electrically connected to the control chip. Preferably, these are cantilever buttons, fixed to the upper housing using a heat-fusion method. This assembly method is robust and simple, effectively controlling costs. Below the buttons is a button control board, which is also electrically connected to the control chip. The upper housing has screen foam, located above the screen body, with a thickness of 1.0mm. The gap between the screen body and the upper housing is 0.8mm, and the screen foam has a compression of 0.2mm, preventing dust from entering and providing cushioning. In the event of a drop or impact, it can absorb some of the force, making the screen less prone to breakage. The upper housing also has light guide pillars, below which is an LED light board connected to the light guide pillar. The LED light board is electrically connected to the control chip, allowing the LED light to be evenly directed to the upper housing. A rib separates the two light guide pillars, preventing interference between the light beams.

[0037] As shown in Figures 2 and 3, the main unit is equipped with a detachable blowing handle, preferably a magnetic connection. For example, the blowing handle has a first magnetic part, and the main unit has a second magnetic part, with the first and second magnetic parts correspondingly connected. During foaming tests, the real-time air pressure value can be detected through the blowing handle, replacing the Valsalva maneuver, which is simple to operate and highly accurate.

[0038] The control chip and the heat-conducting plate of this device are connected by thermally conductive silicone, which has high thermal conductivity and improves heat dissipation efficiency. In addition, a blower is installed under the heat-conducting plate, which can draw in the heat generated by the heat-conducting plate and the control chip and expel it outside the lower housing, which can quickly dissipate heat and thus greatly reduce the temperature of the display screen during use, solving the problem caused by the display screen overheating.

[0039] Example 2

[0040] As shown in Figure 1, in order to enhance the adaptability of this device, a detachable base is provided below the main unit, which can support the main unit and change its height. The base is equipped with casters to facilitate the movement of this device.
