[0019] As a further preferred embodiment of the present invention, the ointment extrusion platform 6 is provided with three extrusion ports 6-1 and one extrusion port 6-2; the extrusion port 6-2 is connected to the extrusion port 6-1, and the ointment is connected above the extrusion port 6-2.

[0020] As a further preferred embodiment of the present invention, the ointment is lidocaine cream.

[0021] As a further preferred embodiment of the present invention, the adjusting arm 2 includes a first connecting rod 2-1, a second connecting rod 2-2, a third connecting rod 2-3 and a fourth connecting rod 2-4 which are hinged in sequence, and the adjusting knob 4 is arranged between the connected connecting rods, one end of the first connecting rod 2-1 is connected to the base 1, and one end of the fourth connecting rod 2-4 is connected to the vascular imager 3.

[0022] As a further preferred embodiment of the present invention, a heating plate 9 is installed on the vascular imager 3; the vascular imager 3 is composed of an image acquisition module, a near-infrared light source module, a projector module and a digital image processing module, and the digital image processing module is respectively connected to the image acquisition module, the near-infrared light source module and the projector module.

[0023] As a specific embodiment of the utility model: lidocaine cream is an anesthetic ointment, which is mostly used in puncture surgery. The compound lidocaine cream is applied to the intact skin surface and covered with a sealed film. The anesthetic effect of the cortex is achieved by releasing lidocaine and prilocaine into the subcutaneous layer and the cortex, and accumulating lidocaine and prilocaine at the cortical pain receptors and nerve endings. Lidocaine and prilocaine are amide local anesthetics. The two stabilize the nerve cell membrane by blocking the ion flow required for the generation and conduction of nerve impulses, thereby producing a local anesthetic effect. This process requires about 20 minutes of drug buffering before it can take effect, which seriously affects the treatment timing and work efficiency. The use of this device can improve the efficiency of drug absorption.

[0024] When in use, first turn on the power, then draw out the patch from the patch storage slot 5, and the patch goes along the guide plate 8 to the bottom of the ointment extrusion platform 6, and the lidocaine cream is squeezed onto the patch through the ointment extrusion platform 6; then the lidocaine cream is evenly applied to the patch through the scraper 7, and then the patch is drawn out and applied to the part where the blood vessel needs to be punctured;

[0025] Loosen the adjusting knob 4 to make the first connecting rod 2-1, the second connecting rod 2-2, the third connecting rod 2-3 and the fourth connecting rod 2-4 move, then adjust the position so that the heating plate 9 is close to the top of the patch, and then lock the adjusting knob 4 to fix the position and increase the temperature of the heating plate 9, so that the docaine cream reacts quickly when heated and exerts its efficacy, which not only shortens the time for the drug to take effect, but also improves the efficiency of drug absorption;

[0026] After the drug takes effect, the patch is torn off, the heating plate 9 is turned off, the vascular imager 3 is turned on to display the vein, and then the blood vessel puncture is performed, which greatly improves the efficiency of blood vessel puncture and relieves the patient's pain.
