Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vein imaging devices, specifically relating to an assembled vein imaging device. Background Technology
[0002] Vein imaging devices are used in pediatrics, emergency medicine, injection departments, inpatient wards, cosmetic surgery (micro-plastic surgery), laboratory medicine, and hematology. In venipuncture, the success rate for infants and young children is approximately 49%. Failed venipunctures increase the number of attempts and the likelihood of venous catheter infection. Obesity, skin color, anemia, low blood pressure, and poor vein quality can all affect the accuracy of puncture. Vein imaging devices allow medical units to observe and locate superficial subcutaneous vessels, assisting in puncture procedures. They are applicable to the whole body for medical aesthetics and varicose vein treatment.
[0003] Most vein imaging devices currently on the market rely on deformation-clamping technology for installation. While this traditional method meets basic requirements to some extent, it reveals numerous inconveniences in practical applications. Because installation requires external force to deform the device, the process is not only cumbersome and complex, causing considerable trouble for users, but frequent disassembly and reassembly can also lead to wear and deformation of the deformable structure. This not only affects the installation stability of the vein imaging device but may also potentially damage its overall performance and lifespan. Utility Model Content
[0004] The purpose of this invention is to provide an assembled vein imaging device to solve the problem of inconvenient operation during the assembly and disassembly of the vein imaging device mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled vein imaging device, including a top cover, a bottom shell installed at its bottom, and a light-transmitting sheet at the top of the bottom shell; it also includes a connecting assembly; the connecting assembly consists of a snap-fit component and a limiting component, wherein: two sets of snap-fit components are provided, one set is located at the top of the bottom shell and snaps into the light-transmitting sheet, thereby realizing the combined installation of the bottom shell and the light-transmitting sheet; the other set of snap-fit components is located inside the top cover and snaps into the bottom shell near its top end; the limiting component is movably inserted through the bottom end of the top cover, and the end of the limiting component is offset against the bottom end of the bottom shell, thereby realizing the installation of the bottom shell and the top cover.
[0006] Preferably, the bottom of the top cover has two parallel slots, and the bottom of the bottom shell has a limiting groove. The end of the limiting groove is through the top cover. The limiting member includes a retaining plate that passes through the slot. The two ends of the retaining plate are not on the same plane and are L-shaped. The long end of the retaining plate passes through the slot at the bottom and abuts against the inner end face of the limiting groove. The bottom shell is installed by abutting. The short end of the limiting groove is inside the top cover and does not contact the limiting groove. An elastic member is also provided between the retaining plate and the top cover. The rebound of the elastic member ensures that the retaining plate always abuts against the limiting groove, thus achieving installation.
[0007] Preferably, the bottom end face of the top cover is provided with a through hole, and the elastic element is a spring disposed inside the through hole. The two ends of the spring are respectively fixed to the inner end face of the through hole and the inner side face of the card plate, so as to push the card plate toward the limiting groove through the through hole.
[0008] Preferably, a protrusion is formed at the bottom of the card plate, which facilitates the card plate to be moved to separate the card plate from the limiting groove. When the card plate moves to the point where the limiting groove and the upper cover pass through, the bottom shell can be separated. In order to ensure the installation of the card plate, both the card plate and the protrusion are made of plastic and have the characteristics of deformation. The longitudinal section of the protrusion is a right trapezoid.
[0009] Preferably, one set of snap-fit components includes a connecting post fixed to the top of the bottom shell, and an insertion hole is provided at the bottom of the light-transmitting sheet for the connecting post to be snapped in, thereby realizing the snap-fit between the two. In order to ensure the stability of the installation, the connecting post and the insertion hole are in an interference fit state.
[0010] Preferably, a movable groove is provided on the inner side of the bottom shell near the top end, and another set of locking components is a limiting post set in the movable groove. The limiting post is fixed on the inner wall of the top cover. The movable groove is inclined towards the bottom end of the bottom shell. When the locking plate abuts against the limiting groove, it will apply a pushing force to the bottom shell. At this time, the limiting post will move towards the inside of the bottom end of the movable groove and achieve the abutment of the two, thereby limiting the position of the top of the bottom shell and preventing the two from separating.
[0011] Preferably, the bottom surface of the top cover is provided with a charging port, which is not shown in the figure. The charging port is separate from the slot and is used for charging. The top cover also contains a motherboard, a lithium battery and other structures. Since such structures and operating principles are existing technologies and are not related to the improvement of this utility model, they will not be described in detail here.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, the original deformation-locking method is innovated into a snap-fit limiting connection method, which not only fundamentally ensures the stability and reliability of the installation process and effectively avoids structural damage caused by deformation, but also realizes the combined installation function between vein imaging devices. Through the snap-fit limiting design, users can easily realize the parallel or series connection of devices to meet the diverse needs of different scenarios. At the same time, this connection method also greatly simplifies the disassembly and assembly process, making the operation more convenient and efficient, saving users valuable time and energy.
