Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a thermal imaging device. Background Technology

[0002] Due to factors such as tissue damage, inflammatory response, and changes in blood circulation, wounds differ in temperature from surrounding healthy tissues. Thermal imaging equipment captures infrared rays emitted by the wound and surrounding tissues using its infrared detectors, converts these infrared signals into electrical signals, and then performs a series of signal processing, amplification, and conversion operations to ultimately form thermal images that represent different temperatures using different colors or grayscale levels, thus visually reflecting the temperature distribution of the wound.

[0003] When taking the picture, the lens of the thermal imaging device needs to be aimed at the wound, and the distance between the lens and the wound should be kept within the optimal measurement distance range recommended by the device (usually 30-50 cm) to ensure that the wound is completely displayed in the field of view of the device.

[0004] In existing technologies, during image acquisition, a 30cm ruler is typically used to measure the distance between the wound and the lens. The ruler needs to be in contact with the skin during shooting. When acquiring images of wounds from multiple patients, the ruler needs to be disinfected repeatedly, which poses a risk of cross-infection. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a thermal imaging device that eliminates the need for a ruler to measure the distance between the thermal imaging device and the wound, thereby reducing the risk of cross-infection.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] This application provides a thermal imaging device, including: a housing, on one side of which is provided a thermal imaging probe for acquiring a wound surface and a ranging probe for detecting the distance between the housing and the wound surface, the ranging probe and the thermal imaging probe being located on the same side of the housing.

[0008] In one embodiment, the housing is further provided with a ranging motherboard, and the ranging motherboard is provided with a first controller, which is electrically connected to the ranging probe.

[0009] In one embodiment, the housing also includes a thermal imaging motherboard, on which a second controller is mounted, and the second controller is electrically connected to the thermal imaging probe.

[0010] In one embodiment, the ranging probe is provided with at least one.

[0011] In one embodiment, a first display screen is provided on one side of the housing. The first display screen is used to display the distance and is connected to the ranging motherboard.

[0012] In one embodiment, a second display screen is provided on one side of the housing. The second display screen is used to display thermal images and is connected to the thermal imaging motherboard.

[0013] In one embodiment, the thermal imaging device further includes a base connected to the housing for supporting the housing.

[0014] In one embodiment, the base and the outer shell can be folded or flipped open relative to each other.

[0015] In one embodiment, the base is connected to the outer casing via a folding mechanism.

[0016] The technical solution of this application has the following effects:

[0017] The thermal imaging device includes a housing with a thermal imaging probe on one side. The thermal imaging probe can acquire the patient's wound surface. On the same side of the housing, there is also a distance measuring probe that can acquire the distance between the patient's wound surface and the housing. In this way, when medical staff use the thermal imaging device, they do not need to use a ruler to measure the distance between the wound and the thermal imaging device. Instead, they can measure the distance between the two sides of the wound directly through the thermal imaging device itself, reducing the use of a ruler and avoiding the risk of cross-infection. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figure 1 As shown, this application embodiment provides a thermal imaging device, including a housing 1. A thermal imaging probe 5 is provided on one side of the housing 1. The thermal imaging probe 5 can acquire the wound surface of the patient. A distance measuring probe 2 is also provided on the housing 1 on the same side. The distance measuring probe 2 can acquire the distance between the wound surface of the patient and the housing 1. In this way, when medical staff use the thermal imaging device, they do not need to measure the distance between the wound surface and the thermal imaging device by using a ruler. Instead, they can measure the distance between the two surfaces directly through the thermal imaging device itself, reducing the use of a ruler and avoiding the risk of cross-infection.

[0027] Optionally, the ranging probe 2 can emit ultrasonic waves; in some cases, the ranging probe 2 can emit lasers; of course, the ranging probe 2 can also emit electromagnetic waves.

[0028] like Figure 4 As shown, in one embodiment, the housing 1 is also provided with a ranging motherboard 3, and the ranging motherboard 3 is provided with a first controller. The first controller is electrically connected to the ranging probe 2. The first controller can be a small single-chip microcomputer or a logic programmable circuit, etc., which is a processor with computing function. It outputs signals to the ranging motherboard 3 to control the operation of the ranging probe 2.

[0029] In addition, the first controller also receives signals output by the ranging probe 2.

[0030] Optionally, after receiving the control signal from the first controller, the ranging motherboard 3 outputs a drive signal to the ranging probe 2, thereby driving the ranging probe 2 to emit an ultrasonic signal.

[0031] like Figure 4As shown, in one embodiment, the outer casing 1 is also provided with a thermal imaging motherboard 6, and a second controller is provided on the thermal imaging motherboard 6. The second controller is electrically connected to the thermal imaging probe 5. The second controller can be a small microcontroller or a logic programmable circuit or other processor with computing functions. It outputs signals to the thermal imaging motherboard 6 to control the operation of the thermal imaging probe 5.

[0032] Optionally, after receiving the control signal from the second controller, the thermal imaging motherboard 6 outputs a drive signal to the thermal imaging probe 5, thereby driving the thermal imaging probe 5 to emit infrared rays and acquire the infrared rays emitted by the reflected wound and surrounding tissue. The second controller converts these infrared signals into electrical signals, which are then processed, amplified, and converted through a series of operations.

[0033] In one implementation, the ranging probe 2 is provided with at least one for emitting ultrasonic waves.

[0034] Optionally, in some cases, the thermal imaging motherboard 6 and the ranging motherboard 3 can be integrated onto a single motherboard.

[0035] Optionally, since the ultrasonic signal is not emitted continuously, only one ultrasonic probe can be installed on the ranging mainboard 3. This probe both emits and receives ultrasonic signals. The ultrasonic probe emits one ultrasonic signal at a time, and after receiving the returned signal, it emits the next ultrasonic signal. In this way, only one ultrasonic probe is installed on the ranging mainboard 3, which can reduce the size of the thermal imaging equipment and lower production costs.

[0036] Alternatively, this embodiment may also include two ultrasonic probes: a ranging probe 2 and a receiving probe, used to transmit ultrasonic signals and receive reflected ultrasonic signals, respectively. Preferably, the ranging probe 2 transmits ultrasonic signals intermittently, meaning it does not transmit ultrasonic signals continuously.

[0037] like Figure 2 As shown, in one embodiment, a first display screen 7 is also provided on one side of the outer casing 1. The first display screen 7 is used to display the distance and is connected to the distance measuring motherboard 3. By setting the first display screen 7, medical staff can more intuitively determine the distance between the wound and the distance measuring probe 2, thereby eliminating the need for measurement by ruler and reducing cross-infection.

[0038] Optionally, the ranging motherboard 3 and the first display screen 7 can be connected by a wire. The first controller sends the calculated distance information to the first display screen 7 through a display interface (such as I2C, SPI, etc.), and the first display screen 7 displays the distance information in the form of numbers or graphics.

[0039] Optionally, the first display screen 7 and the ranging probe 2 are located on two different sides of the housing 1.

[0040] like Figure 2 As shown, in one embodiment, a second display screen 8 is also provided on one side of the outer casing 1. The second display screen 8 is used to display thermal images and is connected to the thermal imaging motherboard 6, so that medical staff can more intuitively see the temperature distribution of the wound.

[0041] Optionally, the first display screen 7 and the second display screen 8 are located on the same side of the housing 1.

[0042] Optionally, the thermal imaging motherboard 6 and the second display screen 8 can be connected by wires. The second controller sends the processed image to the second display screen 8, and the second display screen 8 forms thermal images that represent different temperatures in different colors or grayscale, thereby intuitively reflecting the temperature distribution of the wound.

[0043] like Figure 2 As shown, in one embodiment, the thermal imaging device also includes a base 9, which is connected to the outer shell 1 and is used to support the outer shell 1, so that the thermal imaging device can be more stable during use.

[0044] In one implementation, the base 9 and the outer shell 1 can be folded or flipped open relative to each other. After the thermal imaging device is folded, its size can be reduced, making it easy to carry.

[0045] like Figure 2 As shown, in one embodiment, the base 9 and the outer shell 1 are connected by a folding mechanism 10, thereby enabling the base 9 and the outer shell 1 to flip and fold against each other.

[0046] Optionally, the folding mechanism 10 can be a hinge structure.
