Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a radial artery blood gas pressing device. Background Art

[0002] During the operation, the patient's radial artery puncture is performed to monitor blood pressure. After the operation, the arterial monitoring needs to be removed and the radial artery puncture point is pressed continuously for 10-15 minutes. This process is usually performed by circulating nurses, but the end of the operation is when the circulating nurses are busy. If a timed radial artery puncture point compression hemostatic wristband is used, the patient's radial artery can be pressed for a constant time and the circulating nurses' hands can be freed.

[0003] For example, the invention with the authorization announcement number CN117204905B discloses a local arm compression type radial artery pressurized hemostasis device, including a wristband, a main board, and an observation platform. The wristband is detachably connected to the main board. An observation platform protruding from the main board is provided in the middle of the main board to observe the position of the wound. The observation platform is rotatably connected to the outer cylinder, and a pressure plate assembly is provided in the outer cylinder. The outer cylinder is used to adjust the height of the pressure plate assembly. A positioning rod for precise positioning is provided on the pressure plate assembly to accurately press the wound. The pressure plate assembly includes an upper plate, a connecting rod, and a lower pressure plate. The outer cylinder is threadedly connected to the upper plate, and a plurality of pressure holes are provided on the lower pressure plate. The invention is provided with a raised observation platform, so that the adjustment mechanism such as the outer cylinder and the pressure plate assembly is away from the arm, and a gap is formed between the arm, so as to observe the position of the wound and the degree of pressure. At the same time, the positioning rod is used to assist in accurately pressing the wound, avoiding the poor hemostasis effect caused by large-area pressing and the problem of uncomfortable wearing, thereby achieving a good hemostasis effect.

[0004] When the above scheme is used, when pressing the radial artery, the pressing force cannot be controlled according to the bleeding situation of the radial artery, which may easily cause the pressing force to be too large or too small, causing discomfort to the patient or poor hemostasis effect. At the same time, the bleeding situation cannot be monitored in real time, and the device cannot be automatically released after hemostasis, which is inconvenient to use.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 The present invention provides a technical solution: a radial artery blood gas pressing device, comprising an outer shell 3 and straps 6 arranged on both sides of the outer shell 3, an adjustment port 2 is arranged in the middle of the outer shell 3, and a longitudinal pressing mechanism 1 for controlling the pressing force and monitoring the hemostatic effect is arranged in the adjustment port 2;

[0033] The longitudinal pressing mechanism 1 includes a bearing seat 101, which is arranged in the adjusting port 2. A mounting port 104 is arranged in the middle of the bearing seat 101. A pressing column 102 is movably arranged in the mounting port 104. A hemostasis component 103 is arranged at the bottom of the pressing column 102. The bearing seat 101 is also provided with a driving component. The hemostasis component 103 is used to monitor the bleeding of the radial artery and control the driving component to adjust the pressure of the pressing column 102.

[0034] See also Figure 3 as well as Figure 4The driving assembly includes a first driving gear 107 and a second driving gear 112. The first driving gear 107 is arranged on one side of the first rotating shaft 108, and the second driving gear 112 is arranged on one side of the second rotating shaft 111. The first rotating shaft 108 and the second rotating shaft 111 are symmetrically arranged on both sides of the adjusting port 2. The first driving gear 107 is meshed with the first rack 106, and the second driving gear 112 is meshed with the second rack 113. The first rack 106 is arranged on one side surface of the first adjusting groove 109, and the second rack 113 is arranged on one side surface of the second adjusting groove 110. Through the opposite rotation of the first driving gear 107 and the second driving gear 112, the first rack 106 and the second rack 113 can be controlled to move downward at the same time, and the hemostatic pressure of the pressing column 102 can be controlled. The first adjusting groove 109 and the second adjusting groove 110 are symmetrically arranged on the two side surfaces of the pressing column 102. A transmission structure for controlling the opposite rotation of the first rotating shaft 108 and the second rotating shaft 111 is also arranged in the supporting seat 101. Through the opposite rotation of the first driving gear 107 and the second driving gear 112, the pressing force of the pressing column 102 can be adjusted.

[0035] See also Figure 5 The transmission structure includes a first transmission gear 114 arranged on one side of the first rotating shaft 108, the second transmission gear 118 meshes with the second transmission gear 118, the second transmission gear 118 is arranged on one side of the second rotating shaft 111, the first transmission gear 114 and the second transmission gear 118 are both arranged in a transmission groove 117, and the transmission groove 117 is arranged on the surface of one side of the supporting seat 101. Through the transmission of the first transmission gear 114 and the second transmission gear 118, the first rotating shaft 108 and the second rotating shaft 111 can be controlled to rotate in opposite directions, thereby making the first driving gear 107 and the second driving gear 112 rotate in opposite directions.

[0036] Specifically, a mounting plate 115 is further disposed in the transmission groove 117 , one end of the first rotating shaft 108 is connected to the driving shaft of the first reduction motor 116 , and the first reduction motor 116 is disposed on a side surface of the mounting plate 115 to enable the first rotating shaft 108 to rotate at a reduced speed.

[0037] See also Figure 3 as well as Figure 7The hemostasis component 103 includes a mounting plate 1031, which is arranged at the bottom of the pressing column 102. A hemostasis part 1032 is arranged at the bottom of the mounting plate 1031. A high-definition probe 1034 is arranged on the mounting plate 1031 outside the hemostasis part 1032. The high-definition probe 1034 is connected to the display 105, and the display 105 is arranged at the top of the pressing column 102. The output end of the high-definition probe 1034 is also connected to the input end of the internal controller 8. Specifically, the internal controller 8 is arranged in the first cavity 7, and the first cavity 7 is arranged on one side of the outer shell 3. Through the high-definition probe 1034, the bleeding image around the hemostasis part 1032 can be collected in real time. According to the image, whether there is bleeding outside the hemostasis part 1032 can be monitored in real time, so that the pressing force during hemostasis can be accurately controlled, and the hemostasis part 1032 can be accurately moved to the radial artery puncture port position.

[0038] First, the device is fixed to the patient's wrist by the strap 6, and then the position of the supporting seat 101 is moved by the adjustment mechanism, and the pressing column 102 is moved to the radial artery puncture port position, and the first reduction motor 116 is controlled to rotate forward by the corresponding switch, and the first reduction motor 116 drives the first rotating shaft 108 to rotate, and the first rotating shaft 108 drives the first transmission gear 114 to rotate, and the rotation of the first transmission gear 114 drives the second transmission gear 118 to rotate, and the second transmission gear 118 drives the second rotating shaft 111 to rotate, and the first rotating shaft 108 and the second rotating shaft 111 rotate in opposite directions, and the first rotating shaft 108 and the second rotating shaft 111 drive the first driving gear 107 and the second driving gear 112 to rotate in opposite directions, and the first driving gear 107 and the second driving gear 112 can simultaneously drive the first rack 106 and the second rack 113 through the opposite rotation of the first driving gear 107 and the second driving gear 112. The hemostatic part 1032 moves downward, thereby driving the pressing column 102 to move downward in the mounting opening 104. The pressing column 102 moves downward, driving the mounting plate 1031 to move downward, and the mounting plate 1031 moves downward, driving the hemostatic part 1032 to move downward. When the hemostatic part 1032 is fitted with the radial artery puncture port, as the hemostatic part 1032 moves downward, the high-definition probe 1034 collects the bleeding image around the hemostatic part 1032 and transmits it to the controller. If the image around the hemostatic part 1032 shows bleeding, the internal controller 8 controls the first reduction motor 116 to continue to rotate forward, thereby causing the pressing column 102 to continue to apply pressure. If the image around the hemostatic part 1032 shows bleeding, the internal controller 8 controls the first reduction motor 116 to operate, thereby being able to accurately control the hemostatic pressure of the hemostatic part 1032 on the radial artery puncture port, thereby avoiding the occurrence of excessive or insufficient hemostatic pressure.

[0039] See also Figure 7An invasive blood pressure sensor 1035 is also embedded in the hemostasis part 1032. The output end of the invasive blood pressure sensor 1035 is connected to the input end of the internal controller 8, and the output end of the internal controller 8 is connected to the input end of the first reduction motor 116. The invasive blood pressure sensor 1035 monitors the bleeding pressure at the radial artery puncture site in real time, and controls the time of hemostasis pressing according to whether there is bleeding pressure at the radial artery puncture site.

[0040] At the same time, during the hemostasis process, the invasive blood pressure sensor 1035 monitors the bleeding pressure of the radial artery puncture in real time. When no bleeding pressure is monitored at the radial artery puncture, it means that the hemostasis of the radial artery puncture is completed, and then the internal controller 8 controls the first reduction motor 116 to rotate in the opposite direction, and the first reduction motor 116 drives the first rotating shaft 108 to rotate in the opposite direction. Through the transmission of the first transmission gear 114 and the second transmission gear 118, the first rotating shaft 108 and the first rotating shaft 108 can rotate in the opposite direction, and then the first driving gear 107 and the second driving gear 112 drive the first rack 106 and the second rack 113 to move upward, and drive the pressing column 102 to move upward, so that the hemostasis part 1032 is separated from the radial artery puncture, and automatic loosening is achieved without manual operation.

[0041] Furthermore, a guide slider 120 is provided on one side surface of the pressing column 102, and one end of the guide slider 120 is slidably provided in a guide groove 119. The guide groove 119 is provided on one side surface of the mounting opening 104. When the first rack 106 and the second rack 113 drive the pressing column 102 to move downward, the pressing column 102 drives the guide slider 120 to move in the guide groove 119, thereby guiding the movement of the pressing column 102.

[0042] As a specific embodiment of this application, please refer to Figure 7 as well as Figure 8 The outer surface of the mounting plate 1031 is also sleeved with an auxiliary hemostatic sleeve 1033. Positioning blocks 1036 are arranged on both sides of the inner wall of the auxiliary hemostatic sleeve 1033. The positioning blocks 1036 are movably arranged in the positioning grooves 1037. The positioning grooves 1037 are symmetrically arranged on the surfaces of both sides of the mounting plate 1031. A reset spring 1038 is also arranged on one side of the positioning groove 1037. One end of the reset spring 1038 is connected to the positioning block 1036, which can block the overflowing blood and compress the blood vessels around the radial artery to stop bleeding, thereby improving the hemostasis efficiency.

[0043] When the pressing column 102 presses downward to stop bleeding, the pressing column 102 drives the mounting plate 1031 to move downward, and the mounting plate 1031 drives the auxiliary hemostatic sleeve 1033 to move downward. The auxiliary hemostatic sleeve 1033 fits the patient's skin and wraps the radial artery puncture site. As the pressing column 102 continues to move, the auxiliary hemostatic sleeve 1033 drives the positioning block 1036 to move in the positioning groove 1037 and compresses the reset spring 1038. The elastic force of the reset spring 1038 can make the auxiliary hemostatic sleeve 1033 fit closely to the patient's skin to prevent blood overflow. At the same time, the auxiliary hemostatic sleeve 1033 can press the blood vessels around the radial artery, reduce the blood flow rate, and improve the hemostasis efficiency of the radial artery.

[0044] See also Fig. 9 An adjusting mechanism for controlling the movement of the supporting seat 101 is also provided in the outer shell 3, and the adjusting mechanism includes a ball screw 204, and the ball screw 204 is rotatably arranged in the first groove 202, and the first groove 202 is arranged on one side surface of the adjusting port 2, and one end of the ball screw 204 is also connected to the driving shaft of the second reduction motor 201, and the second reduction motor 201 is arranged in the first cavity 7, and the first cavity 7 is arranged on one side of the outer shell 3. A nut seat 203 is also provided on the ball screw 204, and the nut seat 203 is connected to the supporting seat 101, so as to control the position of the supporting seat 101, and then the hemostasis part 1032 can be accurately moved to the radial artery puncture position.

[0045] When the device is worn on the patient's wrist, the high-definition probe 1034 can transmit images to the display 105. The personnel can adjust the position of the pressing column 102 through the image information of the display 105, and control the forward and reverse rotation of the second reduction motor 201 through the adjustment control switch 4 on the outer shell 3, and control the forward or reverse rotation of the ball screw 204. The nut seat 203 drives the supporting seat 101 to move, and the supporting seat 101 drives the pressing column 102 to move, so as to accurately adjust the pressing column 102 to the radial artery puncture port position, thereby improving the accuracy of hemostasis.

[0046] Furthermore, there is a linear slider 205 on the other side of the supporting seat 101. One end of the linear slider 205 is slidably arranged in the second groove 206. The second groove 206 is arranged on the other side surface of the adjustment port 2. When the nut seat 203 drives the supporting seat 101 to move, the supporting seat 101 drives the linear slider 205 to move in the second groove 206, which can guide the movement of the supporting seat 101.

[0047] A charging interface 5 is also provided on one side of the outer shell 3 of the present application, and the charging interface 5 is connected to a built-in power supply 9.
