Description

Technical Field

[0001] This utility model specifically relates to a vein imaging device that is easy to adjust the angle, belonging to the technical field of vein imaging device equipment. Background Technology

[0002] A vein imaging device is a medical instrument primarily used to help healthcare professionals visualize the venous network beneath a patient's skin, thereby improving the success rate and efficiency of venipuncture procedures (such as blood draws and intravenous infusions). This device projects images of subcutaneous veins onto the skin surface or displays them on a screen using specific technologies, such as near-infrared imaging.

[0003] Existing vein imaging devices primarily rely on support brackets for angle adjustment during use. However, this wide range of angle adjustments has some limitations. Specifically, when the angle of the vein imaging device is adjusted significantly through the support bracket, the large-scale adjustment leads to a significant change in the angle of light incidence, thus affecting image quality (parallax). Therefore, it is necessary to find the optimal viewing angle through multiple attempts, which increases the workload of medical staff and prolongs the operation time. This repeated adjustment not only reduces work efficiency but also brings additional discomfort and anxiety to patients, further affecting the medical experience and making it inconvenient to use.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] A vein imaging device with adjustable angle includes a support 1, the inner cavity of which is provided with an electric telescopic rod 11, and the output end of the electric telescopic rod 11 is fixedly connected to a top rod 2.

[0035] An adjustment assembly 3 is provided at the top of the top rod 2. The adjustment assembly 3 consists of a placement plate 31, two mounting boxes 32, and a connecting box 38. The two mounting boxes 32 are symmetrically arranged on the top surface of the placement plate 31 based on the center line of the placement plate 31. A horizontally placed rotating rod 33 passes through the mounting boxes 32 and is rotatably connected to the mounting boxes 32.

[0036] Inside the mounting box 32, a worm gear 34 is fixedly connected to the rotating rod 33. A worm 35, which matches the worm gear 34, is located at the bottom of the rotating rod 33 and is perpendicular to the rotating rod 33. One end of the worm protrudes from the mounting box 32 to connect to the knob.

[0037] Between the two mounting boxes 32, a rotating rod 33 is fixedly connected to one end of a push plate 36; outside the two mounting boxes 32, a supporting plate 37 is fixedly connected to the rotating rod 33. The other ends of the push plate 36 and the supporting plate 37 are also fixedly connected by a short rod. Furthermore, the other end of the push plate 36 is also fixedly connected to a connecting box 38.

[0038] By rotating the worm gear 35 with the knob, the worm wheel 34 and the rotating rod 33 are rotated, which drives the push plate 36 and the support plate 37 to rotate synchronously, that is, to swing up and down. This, in turn, drives the connecting box 38 and the vein imaging instrument body 311 to swing together, thus completing the adjustment of the up and down tilt angle.

[0039] The support plate 37 is used to provide auxiliary support during the swinging motion of the push plate 36 driven by the rotating rod 33.

[0040] The inner cavity of the connecting box 38 is provided with a guide rod 312 and a running rod 39. One end of the running rod 39 is fixedly connected to a disc 310 outside the connecting box 38. The disc 310 is connected to the vein imaging instrument body 311 via a damping shaft. The other end of the running rod 39 is rotatably connected to the connecting box 38. The guide rod 312 is rotatably connected to the connecting box 38, and one end extends through the connecting box 38. Inside the connecting box 38, the running rod 39 and the guide rod 312 are respectively fixedly connected to two meshing bevel gears 313.

[0041] By rotating the guide rod 312, the guide rod 312 drives the bevel gear 313 to rotate, and the bevel gear 313 then drives the disc 310 to rotate, ultimately causing the vein imaging device body 311 to swing back and forth, thereby achieving the purpose of adjusting the pitch angle.

[0042] After the disc 310 adjusts the angle of the vein imaging device body 311 for the first time, the user can also manually pull the vein imaging device body 311 and make a second fine adjustment with the help of the damping shaft.

[0043] The connecting box 38 is also equipped with a locking mechanism, specifically including:

[0044] A pair of symmetrically positioned limiting rods 314 are located on the front side of the inner cavity of the connecting box 38. The front end of each limiting rod 314 extends to the outside of the connecting box 38 and is equipped with a knob. Two meshing gears 316 are connected to each limiting rod 314. A torsion spring 315 is fitted onto each limiting rod 314 and is linked to the gears 316. A fixing rod 318 is fixedly connected to the outer surface of the rear side of each gear 316.

[0045] Two movable frames 317 are slidably connected to the bottom surface of the connecting box 38, and each has a movable frame on its top; the fixed rod 318 is placed inside the movable frame.

[0046] Locking rods 320 are fixedly connected to opposite sides of the two movable frames 317. Along the circumferential direction, a number of locking grooves 319 are provided on the outer surface of the guide rod 312. The locking rods 320 cooperate with the locking grooves 319 to fix the positioning of the guide rod 312 rotation angle.

[0047] That is, turning the knob rotates the limiting rod 314, driving the two gears 316 to mesh and rotate. The gears 316 further drive the fixed rod 318 to rotate. During the rotation of the fixed rod 318, it pushes the two moving frames 317 to move in opposite directions.

[0048] When the two movable frames move away from each other, the locking lever 320 disengages from the locking groove 319, thus unlocking the device.

[0049] When the two movable frames approach each other, the locking rod 320 is inserted into the locking groove 319 to lock the guide rod 312, thereby locking the angle of the vein imaging device body 311.

[0050] The rotating gear 316 simultaneously applies pressure to the torsion spring 315. After the limit rod 314 is released, the torsion spring 315 can be used to reset the position.

[0051] In summary, this utility model provides a vein imaging device with easily adjustable angles, which, during operation:

[0052] 1. Adjust the height of the vein imaging device body 311: Start the electric telescopic rod 11. The output end of the electric telescopic rod 11 pushes the top rod 2 upward. The top rod 2 drives the adjustment component 3 and the vein imaging device body 311 to move upward in sync, until they reach the appropriate position.

[0053] 2. Adjust the angle of the vein imaging device body 311: By rotating the bracket, the angle of the placement plate 31 can be rotated to make the first circumferential horizontal angle adjustment of the vein imaging device body 311.

[0054] After the horizontal angle along the circumference is adjusted, the vertical tilt angle of the vein imaging instrument body 311 can also be adjusted using a worm gear.

[0055] 3. Use the guide rod 312 to adjust the pitch angle of the vein imaging device body 311 and lock the angle.

[0056] Preferably, the connecting box 38 is made of transparent acrylic material, and its inner cavity is provided with angle scale lines to help observe the rotation angle of the guide rod 312.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
