Description

Technical Field

[0001] The utility model relates to the technical field of hemostat, in particular to an automated radial artery compression hemostat. Background Art

[0002] The radial artery is an important blood vessel in the human wrist, responsible for supplying blood to the hand. More than 90% of coronary angiography and coronary intervention surgeries are performed through the radial artery. Postoperative hemostasis of the radial artery is very important. Long hemostasis time will increase the risk of radial artery occlusion, while short hemostasis time will increase bleeding or hematoma at the puncture site.

[0003] In order to help complete postoperative radial artery hemostasis, the existing technology has a manual radial artery compression hemostat, which drives the silicone pad to compress and stop bleeding by twisting. At the same time, medical staff need to time it themselves and loosen or twist the hemostat at regular intervals.

[0004] In the prior art, medical staff are occasionally unable to check the hemostasis situation in time due to work, and help loosen or twist the hemostat, which makes it difficult to ensure the compression hemostasis time, thereby affecting the patient's postoperative recovery. Utility Model Content

[0005] To this end, the utility model provides an automated radial artery compression hemostat to solve the technical problem in the prior art that the compression hemostasis time is difficult to guarantee and affects the patient's postoperative recovery.

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the present invention provides an automated radial artery compression hemostat, comprising a controller 1 and a humidity sensor 9;

[0024] The controller 1 is fixedly mounted on the first curved panel 3;

[0025] The humidity sensor 9 is installed inside the compression pad 6. A hemostatic pad 7 is installed at the bottom of the compression pad 6. The humidity sensor 9 is used to detect the humidity value of the hemostatic pad 7.

[0026] An air bag 5 is installed on the top of the compression cushion 6, and an air pump 4 is connected to the air bag 5. The air pump 4 inflates the air bag 5 to squeeze the compression cushion 6 to compress the puncture site.

[0027] In order to stabilize the compression cushion 6 , a spring 8 is installed on the top of the compression cushion 6 , and the compression cushion 6 is connected to the air pump housing 2 through the spring 8 .

[0028] In this embodiment, it is necessary to realize both evacuation and inflation of the airbag 5 , and therefore the micro air pump 4 is designed as a bidirectional pump.

[0029] In order to facilitate medical staff to observe the compression time of the hemostat on the patient's puncture site, a timer 10 can be fixedly installed on the second curved plate 14, and the timer 10 is connected to the controller 1;

[0030] After the air pump 4 completes the inflation of the airbag 5, the controller 1 sends an instruction to the timer 10 to start timing until the bleeding is successfully stopped and then sends an instruction to stop timing. The time recorded by the timer 10 each time is the time of compression on the patient's puncture site.

[0031] To facilitate use by patients of different body shapes, an adjustment belt 11 is provided at the end of the second curved panel 14 away from the air pump 4. The second curved panel 14 is connected to the first curved panel 3 through the adjustment belt 11. A Velcro 13 is provided on the adjustment belt 11. The tightness of the compression hemostat can be adjusted by cooperating with the adjustment belt 11 and the Velcro 13.

[0032] In actual use, after the hemostasis is successful, it is usually necessary to remind medical staff to remove the compression hemostat in time. A speaker 12 is set on the timer 10, and the speaker 12 is connected to the controller 1. When the hemostasis is successful, the controller 1 sends an instruction to control the speaker 12 to alarm, reminding medical staff to remove the compression hemostat in time.

[0033] When in use, wear the compression hemostat on the patient's postoperative puncture site and energize it;

[0034] After power is turned on, the humidity sensor 9 will upload the humidity value of the hemostatic pad 7 detected to the controller 1. The controller 1 will control the air pump 4 to inflate the air bag 5, squeezing the compression cushion 6 and the hemostatic pad 7 to press the patient's puncture site to stop bleeding. At the same time, the controller 1 sends a command to the timer 10 to start timing.

[0035] After the set compression time is reached, the controller 1 controls the air pump 4 to extract a small amount of gas from the airbag 5 to reduce the pressure of the hemostatic pad 7 on the puncture site. The humidity sensor 9 detects the humidity value of the hemostatic pad 7 again and uploads it to the controller 1. The controller 1 receives the data and compares it with the data received last time. If the two data are inconsistent, it means that the puncture site is still bleeding. The controller 1 sends an instruction to control the air pump 4 to continue to inflate the airbag 5 to compress the puncture site again.

[0036] Repeat the above operation until the data received by the controller 1 is consistent with the data received last time, which means that there is no blood oozing out of the puncture site. At this time, the controller 1 sends an instruction to control the speaker 12 to alarm, reminding medical staff to remove the compression hemostat in time.

[0037] In summary, the present invention aims to solve the technical problem in the prior art that it is difficult to ensure the time for compression to stop bleeding, thus affecting the patient's postoperative recovery. An automated radial artery compression hemostat is designed. The humidity sensor 9 detects the humidity value on the hemostatic pad 7 at regular intervals and uploads it to the controller 1. The controller 1 receives the data and compares it with the humidity value received last time to see if it is consistent, so as to determine whether there is bleeding at the puncture site, and then controls whether the compression pad 6 continues to apply pressure to the puncture site, thereby avoiding the problem that it is difficult to ensure the time for compression to stop bleeding, thus affecting the patient's postoperative recovery.

The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
