For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] Example 1 Combine Figure 1-17As shown, the present invention provides a portable color ultrasound suitcase, comprising a case 1 equipped with a pull rod 11 and multiple wheels 12; a storage box 2, an adjustment mechanism 3, and a shock-absorbing mechanism 4. The storage box 2 is slidably mounted within the case 1 and is used to accommodate the color ultrasound equipment. The adjustment mechanism 3 is disposed at the bottom of the case 1 and is used to adjust the angle between the wheels 12 at the bottom of the case 1 and the case 1; the shock-absorbing mechanism 4 is disposed within the side walls of the storage box 2 to protect the color ultrasound equipment from collisions. Two tool boxes 6 are slidably mounted within the case 1; the two tool boxes 6 are disposed at the front and rear ends of the case 1, respectively.

[0028] Specifically, the housing 1 is a monolithic outer shell that houses all internal components. It is constructed from high-strength, lightweight materials. All other components are mounted on or within the housing 1, providing physical protection and integrating all functional modules. Recommended materials include aircraft aluminum, carbon fiber composites, and ABS plastic. These materials offer advantages such as lightweight, high rigidity, and waterproof and dustproof design. The interior of the housing 1 is equipped with slide rails for the sliding installation of a storage box 2 and a tool box 6. The storage box 2 is a slidable drawer-like box embedded within the housing 1 and specifically designed to hold the color Doppler ultrasound equipment. Connected to the housing 1 via slide rails, it can slide back and forth within the housing 1. The interior of the storage box 2 also features multiple features to protect the color Doppler ultrasound equipment. A shock-absorbing mechanism 4 acts directly within the storage box to securely store the equipment. Two tool boxes 6 are positioned back-to-back to accommodate other equipment and accessories. Both the storage box 2 and the tool box 6 are equipped with handles and protective locks to prevent them from sliding out when the housing 1 is moved. The pull rod 11 is located on the front side of the box 1 and is retractable. The pull rod 11 is fixed to a position near the bottom of the box 1. A plurality of universal wheels or fixed wheels are installed on the bottom and rear side of the box 1, respectively. The adjustment mechanism 3 is also connected to the bottom of the box 1 for adjusting the angle of the wheels 12 at the bottom of the box 1, and the button for controlling the adjustment mechanism 3 is set at the end of the pull rod 11. The function is to facilitate movement in different terrain environments and to be able to quickly adjust to different movement states according to the terrain. The pull rod 11 is made of aluminum alloy, and the wheels 12 are made of polyurethane wheel surface + steel bearings. A support frame 7 for placing flat plates or other materials is placed in the tool box 6. The support frame 7 includes a mutually hinged adsorption plate 71 and a folding plate 72. When in use, the adsorption plate 71 is supported in a suitable position, and then the folding plate 72 is unfolded according to the size of the item. This design improves the personalization of the device and makes the suitcase more functional.

[0029] Furthermore, the adjustment mechanism 3 includes a movable rod 31, two hydraulic telescopic rods 32, a first conduit 33 and an auxiliary device 34; one end of the movable rod 31 is connected to the wheel 12, and the other end is rotatably connected to the box body 1; one end of the two hydraulic telescopic rods 32 is connected to the rear end of the box body 1, and the other end is connected to the movable rod 31; the first conduit 33 is arranged between the two hydraulic telescopic rods 32 and is connected, and is used to store liquid; the auxiliary device 34 is arranged at the rear end of the box body 1, and is connected to the hydraulic telescopic rod 32, and is used to support the ground to assist in carrying the box body 1.

[0030] A storage compartment 14 is provided at the bottom of the box body 1 for storing the adjustment mechanism 3. A bracket 16 is provided in the storage compartment 14. The movable rod 31 is an electric push rod, the fixed end of which is rotatably sleeved on the bracket 16. The movable end is connected to a fixed rod 1, and both ends of the fixed rod 1 are connected to wheels 12. In addition, an electric telescopic rod 38 is provided inside the box body 1. The telescopic end of the electric telescopic rod 38 passes through the box body 1 and enters the storage compartment 14, and is connected to the movable rod 31 at the same time. The two hydraulic telescopic rods 32 are connected to the fixed part of the movable rod 31 through the fixed rod 2. When the electric telescopic rod 38 is extended or retracted, the length of the movable rod 31 remains unchanged, and the movable rod 31 can rotate around the bracket 16 to squeeze the hydraulic telescopic rod 32 to retract or retract. The greater the contraction of the hydraulic telescopic rod 32, the smaller the angle between the movable rod 31 and the box body 1, the larger the angle between the box body 1 and the ground, and the greater the distance between the handgrip part of the pull rod 11 and the ground. Conversely, the smaller the distance between the handgrip part of the pull rod 11 and the ground, this design helps users of different heights to adjust according to their own habits, so that the suitcase is in the most labor-saving state. The first conduit 33 is used to store and circulate hydraulic oil. A corresponding hydraulic oil tank 37 is also provided in the storage compartment 14. The hydraulic oil tank 37 is arranged parallel to and in communication with the first conduit 33 below the first conduit 33. The ends of the two hydraulic telescopic rods 32, away from the movable rod 31, are both rotatably connected to the outer wall of the hydraulic oil tank 37. When the movable rod 31 is extended or retracted, the two hydraulic telescopic rods 32 can rotate around the hydraulic oil tank 37, facilitating the storage of the movable rod 31 and the hydraulic telescopic rod 32 into the storage compartment 14. The storage compartment 14 is provided with a cover 15, which is movably provided at the bottom of the box body 1 and is used to close the storage compartment 14. The hydraulic telescopic rod 32 can act on the auxiliary device 34, allowing the movable rod 31 and the auxiliary device 34 to operate simultaneously, achieving the purpose of saving effort when climbing stairs.

[0031] Furthermore, the auxiliary device 34 includes an L-shaped push plate 341, two hydraulic push rods 342 and two second guide tubes 343; the push plate 341 is movably arranged behind the box body 1 for supporting the ground; the two hydraulic push rods 342 are both arranged at the rear end of the box body 1, and the ends are connected to the push plate 341 for driving the push plate 341 to extend and retract; the two second guide tubes 343 are respectively connected and arranged between the corresponding hydraulic telescopic rods 32 and the hydraulic push rods 342.

[0032] An L-shaped push plate 341 is located at the rear bottom of the housing 1 and can extend and retract along the housing 1. When retracted, the edge of the push plate 341 aligns with the corresponding edge of the housing 1. A hydraulic push rod 342 is sleeved within the housing 1, its telescopic end connected to the push plate 341. A second L-shaped conduit 343 is connected to the sidewall of the hydraulic telescopic rod 32 at one end and to the top of the hydraulic push rod 342 at the other. Hydraulic oil within the hydraulic telescopic rod 32 flows through the second conduit 343 into the hydraulic push rod 342, driving the telescopic end of the hydraulic push rod 342 to push the push plate 341.

[0033] Furthermore, first control valves 35 are provided at both ends of the first conduit 33 ; and second control valves 36 are provided on both of the second conduits 343 .

[0034] Working Principle: During use, the user controls the extension of the electric telescopic rod 38 as needed, driving the movable rod 31 to rotate and squeeze the hydraulic telescopic rod 32, causing the hydraulic telescopic rod 32 to retract. At this time, the second control valve 36 is closed and the first control valve 35 is opened, allowing the hydraulic oil in the hydraulic telescopic rod 32 to enter the hydraulic oil tank 37 through the first conduit 33. When the movable rod 31 reaches the desired angle, the electric telescopic rod 38 is closed, and the wheels 12 on the box body 1 support the box body 1 in a state that saves the user effort. When the hydraulic telescopic rod 32 is squeezed, the first control valve 35 is closed and the second control valve 36 is opened, and the hydraulic oil enters the hydraulic push rod 342 through the second conduit 343, causing the hydraulic push rod 342 to extend and push the push plate 341 toward the ground, thereby providing assistance when the user lifts the box body 1, achieving the purpose of saving effort.

[0035] Example 2 On the basis of the first embodiment, the second embodiment provides a specific structure of the shock absorbing mechanism 4, which improves the protection of the color Doppler ultrasound equipment in complex environments.

[0036] Specifically, the shock absorbing mechanism 4 includes a first support plate 41, a ring potentiometer 42, and a frame-shaped magnetic field portion 43; the first support plate 41 is movably arranged on the inner bottom surface of the storage box 2, and its end is connected to the power supply, used to support the bottom of the color ultrasound equipment; the ring potentiometer 42 is arranged below the first support plate 41 and electrically connected to the end of the first support plate 41 for changing the current; the frame-shaped magnetic field portion 43 is arranged below the first support plate 41 and electrically connected to the end of the ring potentiometer 42 for magnetically attracting the first support plate 41.

[0037] The ring potentiometer 42 and the frame-shaped magnetic field portion 43 are both disposed inside the storage box 2 , and a motor 44 is also disposed next to the ring potentiometer 42 .

[0038] Furthermore, the first support plate 41 includes a support plate 411, multiple elastic blocks 412 and a contact block 413; the support plate 411 is slidably connected to the bottom of the storage box 2 and is used to support the bottom of the color ultrasound equipment; multiple elastic blocks 412 are connected between the support plate 411 and the storage box 2 and are used to buffer the gravity acting on the support plate 411; the contact block 413 is arranged at the end of the support plate 411 and is slidably connected to the ring potentiometer 42 and is used to adjust the effective length of the ring potentiometer 42 to achieve adjustment of the magnetic force of the magnetic field part 43.

[0039] It should be noted that multiple elastic blocks 412 are positioned at the four corners of the support plate 411. A slider is positioned in the middle of the support plate 411. The slider is connected to the motor 44 and slidably connected to the bottom of the storage box 2. A contact block 413 is positioned on the side wall of the slider and contacts the ring potentiometer 42. When current flows through the slider, it passes through the contact block 413 and then through the ring potentiometer 42 to the electromagnetic unit. Different current levels result in different magnetic forces generated by the electromagnetic unit. When the color Doppler ultrasound device is placed on the support plate 411, the support plate 411 moves downward due to gravity, squeezing the elastic blocks 412. Simultaneously, the downward movement of the slider causes the contact block 413 to slide along the ring potentiometer 42. The position of the contact block 413 on the ring potentiometer 42 affects the amount of current flowing through. At this point, when the shock absorber 4 is not moving, it is in a state of equilibrium.

[0040] Furthermore, the shock absorbing mechanism 4 further includes a second support plate 45 movably disposed on the rear side of the storage box 2 , with an end portion connected to a power source, for supporting the rear side of the color ultrasound device to protect the color ultrasound device.

[0041] The second support plate 45 has the same structure and principle as the first support plate 41 except for its size. The rear side of the storage box 2 is provided with a ring potentiometer 42 , a frame-shaped magnetic field portion 43 , and a motor 44 , which are of the same principle but different models as those at the bottom of the storage box 2 .

[0042] Working principle: When the wheel 12 is hit or moves too much when passing through a road with complex terrain, the first support plate 41, the second support plate 45 and the color ultrasound equipment will tend to squeeze the elastic block 412 under the impact, and at the same time drive the contact block 413 to slide along the corresponding annular potentiometer 42, so that the effective length of the annular potentiometer 42 becomes shorter, and the current passing through becomes smaller, so that the magnetic force generated by the electromagnetic field becomes smaller, and the suction force on the corresponding support plate 411 is reduced, so that the color ultrasound equipment can quickly return to its original equilibrium state under the impact.

[0043] Example 3 In order to make the device more portable and improve the operating stability of the device, a positioning groove 13 for placing the color ultrasound device is opened on the top of the box 1; a heat dissipation mechanism 5 for cooling the color ultrasound device is provided between the positioning groove 13 and the box 1.

[0044] Specifically, the heat dissipation mechanism 5 includes an air pump 51 and an air storage portion 52; the air pump 51 is arranged inside the housing 1, connected to the positioning slot 13, and is used to deliver airflow to the surrounding areas of the positioning slot 13; the air storage portion 52 is arranged inside the housing 1 and is located around the positioning slot 13, and is connected to the air pump 51 through an air pipe 53. A plurality of air outlet holes 131 are opened between the positioning slot 13 and the air storage portion 52. A gravity-sensing airbag 55 is provided in the positioning slot 13, and a plurality of suction cups 56 are provided on the gravity-sensing airbag 55. The suction cups 56 are used to place the color ultrasound equipment more stably in the positioning slot 13. A filter 54 is provided on the housing 1 above the air pump 51.

[0045] Working principle: When in use, the color ultrasound device is taken out of the storage box 2 and placed on the gravity-sensing airbag 55 in the positioning slot 13. The gravity-sensing airbag 55 is subjected to gravity and activates the air pump 51. The air pump 51 transports the air flow through the air pipe 53 to the air storage part 52, and then blows the air to the surrounding areas of the color ultrasound device through the air outlet 131, thereby achieving the purpose of heat dissipation for the color ultrasound device.

[0046] Specific application cases A portable color ultrasound suitcase is used at emergency scenes, where medical personnel need to quickly carry color ultrasound equipment to the scene of an accident or a patient's home for diagnosis. It is also used for medical treatment in remote areas, where doctors in areas with scarce medical resources carry equipment to rural areas for medical rounds. When roads are poor, there are no elevators, and long distances are required, the suitcase's 12 adjustable wheels and auxiliary support of a push plate 341 can reduce the difficulty of carrying the equipment. The suitcase is also used for battlefield medical treatment, in extreme environments such as military field hospitals, earthquake-stricken areas, and mountainous areas.

[0047] This application provides a portable color ultrasound suitcase. When the device is in use, the specific operation process is as follows: According to the ground conditions (such as stairs, ramps, muddy ground), the angle between the wheels 12 and the box 1 is adjusted by controlling the hydraulic telescopic rod 32; if greater assistance is needed, the hydraulic push rod 342 in the auxiliary device 34 can be activated to extend the L-shaped push plate 341 downward to support the ground and reduce the carrying burden; During transportation, the first support plate 41 and the elastic block 412 absorb vibrations together, while the magnetic field unit 43 dynamically adjusts the magnetic force according to the magnitude of the vibrations to achieve active vibration reduction. Open the box cover and take out the device from the positioning slot 13; use the vacuum pump 51 to introduce air into the air storage part 52 to cool the surface of the device and extend its service life; open the front and rear tool boxes 6, take out the probe, charger, data cable, disinfectant, etc., and prepare to use the device.
