Problems solved by technology

[0004] The Chinese patent No. ZL200620066615.5 discloses a transparent inflatable tourniquet, which uses manual air injection, adjusts the compression pressure and compression time according to experience, cannot monitor the blood flow blocking effect and timely Adjust the applied pressure and blocking time, so there are often situations where the applied pressure is too high or too low, and the maintenance time is too long or too short, which is likely to cause corresponding complications, including complications caused by too low pressure and too short compression time. Hemorrhage and hematoma at the puncture site, ischemic necrosis of the radial artery and fingers caused by excessive pressure and prolonged compression

Embodiment 1

[0036] like Figure 1-3 As shown, the radial artery dual airbag intelligent compression hemostasis device of this embodiment includes a wristband 1, a radial artery airbag 2, an ulnar artery airbag 3, a blood oxygen saturation monitoring probe 4, a pressure sensor 24, a program-controlled air pump 25, and a program-controlled switch 26 and the control terminal 7, the radial artery balloon 2 and the ulnar artery balloon 3 are arranged on the wristband 1 at intervals, the wristband 1 is provided with an arc cavity 17, and the radial artery balloon 2 and the ulnar artery balloon 3 are arranged in the arc cavity 17. Wherein, the two ends of the wristband 1 are connected by Velcro 18 velcro, which is convenient for adjusting the size of the wristband according to different wrist sizes. Of course, the wristband can also be of other structures.

[0037] like Figure 9 As shown, the radial artery balloon 2 and the ulnar artery balloon 3 are respectively connected with a programmed a...

Embodiment 2

[0058] The difference between this embodiment and embodiment 1 is: as Figure 6 As shown, there is a fixed rubber sleeve 5 for fixing the casing 9 on the wristband 1, and the fixed rubber sleeve 5 and the air bag are respectively located on the upper surface and the lower surface of the wristband 1, as shown in FIG. Figure 7 As shown, there is a bayonet part 23 adapted to the fixed rubber sleeve 5 on the back of the casing 9, such as Figure 8 As shown, the bayonet part 23 is plate-shaped, and one end of the bayonet part 23 has a barb. The control terminal 7 can be fixed on the wristband 1 by buckling the bayonet part 23 and the fixing rubber sleeve 5 . Wherein, the bayonet part 23 is a rectangle with a length of 45 mm, a width of 30 mm, an overall thickness of 3 mm, and an undercut length of 5 mm. Wherein, casing 9 is rectangular, and its length is 62.5mm, and width is 50mm; Display screen is rectangular, and its length is 37.5mm, and width is 35mm; On the upper part of t...

Abstract

The invention relates to a radial artery dual-airbag intelligent compression hemostasis device which comprises a wristband, a radial artery airbag, an ulnar artery airbag, an oxyhemoglobin saturation monitoring probe, a pressure sensor, a program control air pump, a program control switch and a control terminal. The radial artery airbag and the ulnar artery airbag are arranged on the wristband in a spaced mode and connected with the program control air pump. Connecting pipe fittings of the airbags and the program control air pump are provided with an air outlet and a pressure sensor. The program control switch is arranged at the air outlet. The control terminal comprises a single-chip microcomputer, a man-machine interaction operation button and a displayer. The radial artery oxyhemoglobin saturation monitoring result can be converted into signals of waveform, oxyhemoglobin saturation value and sound intensity of pulse waves, the single-chip microcomputer determines the pressure exerted on a patient radial artery according to the signals, the inflation pressure in the airbags is fed back and adjusted through the program control air pump and the program control switch, and the blood vessel complications and damage which are caused to a patient when the pressure in the airbags is too high or too low and the pressing time is too long or too short are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radial artery double-airbag intelligent compression hemostasis device. Background technique [0002] Coronary heart disease is a type of ischemic heart disease, which is narrowed or blocked by atherosclerosis or vasospasm in the coronary arteries (vessels responsible for supplying blood and oxygen to the heart), resulting in myocardial ischemia and hypoxia (angina pectoris) or Heart disease with death of heart muscle (myocardial infarction). [0003] Coronary angiography can be used to understand whether there are stenotic lesions in the blood vessels, make a clear diagnosis of the lesion location, extent, severity, and condition of the vessel wall, determine the treatment plan (intervention, surgery or medical treatment), and can also be used to judge the curative effect. The arteries of the extremities are mostly used as the approach, especially the most commonly use...
