Description

Technical Field

[0001] The utility model relates to the technical field of medical detection auxiliary equipment, in particular to a positioning device for arterial blood vessel detection. Background Art

[0002] Arteries are blood vessels that carry blood away from the heart. After they are sent out from the ventricles, they branch repeatedly, becoming thinner and thinner, and finally migrate to capillaries. The walls of arteries are thicker and can withstand greater pressure. The walls of large arteries have more elastic fibers and are more elastic. When the ventricles eject blood, the walls expand, and when the ventricles relax, the walls retract, prompting the blood to continue to flow forward. The smooth muscles of the walls of medium and small arteries, especially small arteries, are more developed and can contract or relax under neurohumoral regulation to change the lumen and size, affecting local blood flow resistance. The blood flows fast. The definition of arteries in traditional Chinese medicine is: the pulse is a few pulses, seen in the upper and lower parts, without head and tail, as big as beans, and trembling.

[0003] The existing positioning device for arterial blood vessel detection is basically fixed by a strap. When in use, the strap must first be wrapped around the patient's wrist and then fixed by a buckle or Velcro. The use process of the above positioning device is relatively cumbersome, and at the same time, the fixing pressure on the patient's wrist cannot be guaranteed. Utility Model Content

[0004] The utility model aims to provide a positioning device for arterial blood vessel detection, which has the characteristics of simple operation, convenient use and ensuring moderate fixing pressure.

[0008] In order to provide power for the rotation of the fourth bevel gear, as a preferred positioning device for arterial blood vessel detection of the utility model, a motor is installed on the left side wall of the fixed box, and the output end of the motor passes through the fixed box and is fixedly connected to the fourth bevel gear.

[0009] In order to relax the patient's hands, as a preferred positioning device for arterial blood vessel detection of the utility model, a hemispherical hand rest is fixedly connected to the left end of the upper end surface of the fixing box.

[0010] In order to increase the comfort of the patient's wrist, as a preferred positioning device for arterial blood vessel detection of the utility model, a protective cushion is fixedly connected to the interior of the placement groove.

[0011] In order to facilitate the pressure sensor to control the motor to shut down, as a preferred positioning device for arterial blood vessel detection of the utility model, the pressure sensor is electrically connected to the motor.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Through the mutual cooperation between multiple bevel gears, the two winding rollers rotate, and the two winding rollers pull the two ends of the restraint belt, so that the two ends of the restraint belt are respectively wrapped around the outer walls of the two winding rollers, thereby tightening the restraint belt. When the tightening pressure of the restraint belt reaches the value set for the pressure sensor, the two first bevel gears stop rotating to prevent the restraint belt from being too tight around the patient's wrist, thereby fixing the patient's wrist to the upper end of the fixing box through the restraint belt.
