Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-3, the present embodiment provides an auxiliary device for facilitating radial artery puncture, which includes a base 1.

For convenient wrist placement, the upper end of the base 1 is provided with a placing plate 2.

One end of the placing plate 2 is provided with an inclined plane for placing a palm, the palm center is inclined upwards by arranging the inclined plane, an angle between 100 degrees and 150 degrees is formed between the palm and the forearm, and the artery position is well exposed.

For the convenience of medical care to puncture, need adjust the angle of forearm, for the convenience of adjusting the forearm angle, place board 2 and rotate and install in the upper end one side of base 1.

Wherein, the junction of base 1 and placing board 2 is fixed with pivot 12, makes placing board 2 rotate above base 1 through pivot 12.

In order to adjust the angle of the placing plate 2 conveniently, the upper end of the base 1 is slidably provided with a sliding strip 3.

The sliding bar 3 is located below the placing plate 2 and contacts the placing plate 2, and the placing plate 2 can be tilted when the sliding bar 3 moves close to the rotating shaft 12, so that the angle between the placing plate 2 and the base 1 is changed.

In order to move the sliding strip 3 conveniently, a moving mechanism 4 is fixedly arranged in the base 1.

The moving mechanism 4 comprises a moving block 41 and a threaded rod 42, the moving block 41 is provided with a threaded hole matched with the threaded rod 42, the moving block 41 is installed on the threaded rod 42 through the threaded hole, the upper end of the moving block 41 is connected with the sliding strip 3, the threaded rod 42 is rotatably installed in the base 1, the moving block 41 is enabled to move in the base 1 through rotating the threaded rod 42, and then the sliding strip 3 is driven to move on the base 1.

In order to facilitate turning of the threaded rod 42, a knob 43 is rotatably mounted at one end of the base 1.

Wherein, the knob 43 is fixedly connected to one end of the threaded rod 42, and the threaded rod 42 is driven to rotate along with the knob 43.

In order to stably move the slide bar 3 at the upper end of the base 1, a slider 31 is fixedly connected to the lower end of the slide bar 3.

Wherein, the spout 11 that matches with slider 31 is seted up to the upper end of base 1, slides in spout 11 through slider 31 and makes slide bar 3 steady movement on base 1, and in order to make slide bar 3 remove more stably, slider 31 prefers to set up to two, is located the lower extreme both sides of slide bar 3 respectively.

In order to prevent slide bar 3 from jamming at the lower end of placing plate 2 during movement, roller 32 is rotatably mounted on the upper end of slide bar 3.

Wherein the roller 32 is attached to the lower end of the placing plate 2, and the roller 32 is rotated at the lower end of the placing plate 2 when the slide bar 3 is moved.

In order to fix the base 1 on a table more stably, a rubber pad 5 is fixedly connected to the lower end of the base 1.

The rubber pad 5 is preferably made of rubber, and certainly, the rubber pad is not limited to rubber materials, and can also be made of plastic and other materials, so that the base 1 can be fixed as long as the damping between the rubber pad and the desktop can be increased.

Example 2

Please refer to fig. 4-6, a further improvement is made on the basis of the embodiment 1:

a driving gear 44 and a driven gear 45 are rotatably mounted in the base 1.

Wherein, driving gear 44 and driven gear 45 intermeshing, driving gear 44 cup joints and installs the one end at knob 43, and driven gear 45 cup joints and installs the one end at threaded rod 42.

The driving gear 44 is driven to rotate by rotating the knob 43, and the driving gear 44 rotates to drive the meshed driven gear 45 to rotate, so as to drive the threaded rod 42 to rotate.
