Description

Technical Field

[0001] The present invention relates to the technical field of venous blood vessel imagers, and in particular to an adjustable venous blood vessel imager. Background Art

[0002] A venous imaging device is a medical device used to visualize human veins. Through the imaging device, the location and path of the veins can be clearly seen, helping medical staff to find veins more accurately when performing intravenous injections, blood draws or cannulation. For patients with thin or difficult-to-reach veins, the imaging device can significantly improve the success rate of the operation and reduce the need for multiple punctures.

[0003] However, existing imagers usually do not have the function of supporting the hands, which makes injection more troublesome, especially when a specific posture needs to be maintained for a long time for the imager to scan, which can easily lead to poor imaging results and increase the difficulty of examination. The patient may affect the accurate imaging of veins due to hand shaking or fatigue. Secondly, the projection head of the traditional imager does not have the function of flexible adjustment. It cannot be flexibly adjusted according to the patient's body shape, posture or specific vein location, which not only limits the coverage of the imaging, but also may cause the imaging quality to decline due to poor light angles, making it difficult to clearly identify the subtle vein structure, increasing the complexity and uncertainty of the operation;

[0004] Therefore, an adjustable venous vessel imager is proposed. Summary of the invention

[0005] The main purpose of the present invention is to provide an adjustable venous vessel imager, which can effectively solve the technical problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] An adjustable venous blood vessel imager comprises an instrument body, a connecting rod and a projection head are arranged above the instrument body, gear 1, gear 2 and gear 3 are arranged inside the connecting rod, gear 1 is meshed with gear 2, gear 2 is meshed with gear 3, gear 1, gear 2 and gear 3 are all movably connected to the connecting rod, a rotating rod 1 is fixedly installed at the center position of gear 1, and rotating rod 1 is also movably connected to the connecting rod, a rotating rod 2 is fixedly installed at the center position of gear 3, rotating rod 2 is movably connected to the connecting rod, rotating rod 2 is fixedly connected to the projection head, a threaded rod 1 is arranged through the top of the connecting rod, and threaded rod 1 is threadedly connected to the connecting rod.

[0008] As a further solution of the present invention, a placement plate and a clamp are provided at the front of the instrument body. The placement plate is located below the projection head. Clamp slots are provided on both sides of the outside of the placement plate. The width of the clamp slots is greater than that of the clamp.

[0009] As a further solution of the present invention, the clamping member is composed of a round rod and a hand rod, and the round rod is movably connected to the instrument body.

[0010] As a further solution of the present invention, a slide groove is opened through the front part of the instrument body, and a connecting piece is arranged on the inner side of the slide groove. The connecting piece is slidably connected to the instrument body through the slide groove. Cross bars are arranged on both sides of the outside of the connecting piece, and the cross bars are movably connected to the placement plate.

[0011] As a further solution of the present invention, a storage groove is opened through one side of the outer side of the placement plate, and two groups of support rods are arranged in the storage groove.

[0012] As a further solution of the present invention, two groups of plug-ins are arranged through the front and rear parts of the placement plate, the plug-ins are fixedly connected to the support rods, and the two groups of plug-ins are movably connected to the placement plate, bolts are arranged through the front parts of the plug-ins, and the bolts are threadedly connected to the placement plate.

[0013] As a further solution of the present invention, rack rods are provided inside the two groups of support rods, the rack rods are meshingly connected with a worm gear, and the worm gear is rotationally connected to the support rods.

[0014] As a further solution of the present invention, the worm wheel is meshingly connected with a worm, and the worm is rotationally connected to the support rod.

[0015] The beneficial effects of the present invention are as follows:

[0016] By setting up the placement board, the hand can have a place to support when performing projection, which is convenient for puncture after projection. When in use, the placement board is turned over to be horizontal with the desktop, the plug-in is rotated so that the support rod is perpendicular to the desktop of the instrument body, and the plug-in is fixed by bolts, so that the hand can be placed on the placement board, which is convenient for projection puncture;

[0017] The placement plate can be flexibly adjusted in height by directly rotating the worm. The rotation of the worm drives the worm wheel meshing with it to rotate. The rotation of the worm wheel drives the rack rod meshing with it to move, so that the rack rod can extend from the support rod. When the support rod extends, the placement plate will move upward, and the connecting piece will slide in the slide slot to complete the adjustment of the height of the placement plate.

[0018] By setting the card piece, the placement plate can be reasonably stored when not in use, so as not to occupy space. When in use, the placement plate is directly rotated, the card piece passes through the card slot, and finally the card piece is rotated so that the card piece can fix the placement plate.

[0019] The angle of the projection head can also be adjusted. When using it, first twist the threaded rod one so that the threaded rod one does not squeeze the gear two, and the gear two can rotate smoothly. Then rotate the rotating rod one, and the gear one drives the gear two meshing with it to rotate. The gear two drives the gear three meshing with it to rotate. The gear three is fixedly connected to the rotating rod two, so the gear three drives the rotating rod two to rotate. The rotating rod two is fixedly connected to the projection head, so the rotating rod two drives the projection head to rotate. After the adjustment is completed, rotate the threaded rod one so that the threaded rod squeezes the gear two to limit the position, thereby fixing the angle of the projection head.
