Problems solved by technology

[0003] At present, the operating bed in the cardiac interventional catheterization room is equipped with a movable arm support frame, which is easy to fall, is not fixed securely, and the angle of arm expansion is not easy to adjust. The material of the support plate is relatively hard. Use this method to expose the puncture site of the radial artery. The comfort is poor, and the patient will experience arm pain, numbness and other uncomfortable sensations if left for too long; when injecting anesthetics and puncturing, there will be voluntary movement due to pain, and the gauze roll will also easily shift. lead to puncture failure

Embodiment 1

[0033] Please refer to figure 1 , a radial artery puncture device, used to fix the arm to be punctured, the radial artery puncture device includes a mounting block 1, a support part 2 and a fixing part 3, the support part 2 is installed on the mounting block 1, and the support part 2 includes a The raised part 21 at the position to be punctured and the recessed part 22 for placing the palm, the fixing part 3 is installed on the mounting block 1 to fix the arm to be punctured. It is arranged above the depression 22 and parallel to the top surface of the depression 22. When in use, the patient’s arm is placed on the support part 2, and the palm is placed on the depression 22. At the same time, the palm is facing upwards, and the hand holding column is held to avoid puncture. The palm is not fixed and moves, and the site to be punctured is placed on the raised part 21, and the site to be punctured is raised by the raised part 21, fully exposing the site to be punctured, which is ...

Embodiment 2

[0041] This embodiment includes all the content of Embodiment 1. The difference is that due to differences in human body, the degree of radial artery is different for each person. Some patients can puncture very conveniently without the very high degree of protrusion of the raised portion 21. , and the degree of protrusion of the raised portion 21 greatly determines the comfort level of the patient. Therefore, in this embodiment, the raised portion 21 is a telescopic structure, and the stretching of the raised portion 21 is realized by an airbag. Optionally, an airbag is provided inside the raised part 21, and a soft material layer is laid on the surface. When the hand is put into the radial artery puncture device, the airbag is inflated until the radial artery is obvious enough to be easily punctured. To deflate, the airbag can also be directly used as the raised part. Using the above method, the raised degree of the raised part can be adjusted according to the different condi...

Embodiment 3

[0043] This embodiment provides a radial artery puncture support frame, including the support frame body 5 and the radial artery puncture device provided in embodiment 1 or embodiment 2. The radial artery puncture device is installed on one end of the support frame body 5, because each person's arm The length is different. In this embodiment, the support frame body 5 is a telescopic rod, which is adjusted to a suitable position according to the patient's arm length. Because the same posture is placed for a long time, the patient feels uncomfortable, and even feels numbness, pain, and cold extremities. For this reason, the support frame body 5 and / or the radial artery puncture device are provided with air cushion massage strips for massaging the arms, and the air cushion massage strips can be used to massage the punctured limbs regularly to promote blood circulation and increase comfort, while preventing upper arm veins from thrombus.

Abstract

The invention provides a bed, supporting frame and device for radial artery puncture, and relates to the technical field of medical devices. The device includes an installation block, a supporting part and a fixing component; the supporting part is installed on the installation block, and the supporting part includes a convex part for supporting the position, to be punctured of an arm and a concave part where a palm is put; and the fixing component is installed on the installation block to fix the arm to be punctured. According to the device, the convex part and the concave part are designed,the height of the concave part and the arm is the same, so that the patient palm can be conveniently put in the concave part to avoid slipping and unstable placement, and the convex part raises a wrist to fully expose the position of the wrist to facilitate the radial artery puncture.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radial artery puncture bed, a support frame and a puncture device. Background technique [0002] Coronary angiography is mainly through the radial artery puncture, according to the shape of the blood vessel to send the contrast catheter into the coronary artery of the heart and inject a contrast agent for imaging. It is one of the most commonly used methods for diagnosing coronary heart disease. [0003] At present, the operating bed in the cardiac interventional catheterization room is equipped with a movable arm support frame, which is easy to fall, is not fixed securely, and the angle of arm expansion is not easy to adjust. The material of the support plate is relatively hard. Use this method to expose the puncture site of the radial artery. The comfort is poor, and the patient will experience arm pain, numbness and other uncomfortable sensations if left for too long...
