Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an air bag compression hemostat. Background Art

[0002] Compression hemostasis is the most convenient and quickest way to stop bleeding in response to trauma and during surgery. It uses external force to compress the blood vessels at the bleeding site to shrink or close them to slow down blood flow, allowing platelets, fibrin, red blood cells, etc. to function to form thrombi, thereby further achieving the purpose of hemostasis. It is suitable for situations where the wound is relatively small. In severe cases, it cannot last long and is only used to temporarily control bleeding when emergency measures are taken. It mainly uses mechanical pressure to compress the femoral artery puncture site from outside the body to promote hemostasis and healing of the puncture site;

[0003] China Patent Network has published an airbag compression hemostat, with publication number CN219070474U, which includes a base, a hemostat body is arranged on the top of the base, a compression plate and an adjustment plate are arranged in the inner cavity of the hemostat body, a flexible pad is arranged at the bottom of the compression plate, and a compression airbag is arranged in the inner cavity of the compression plate. For the airbag compression hemostat, when the hemostatic site is located in the hemostat body, the adjustment knob is rotated to drive the screw to rotate, and then under the action of the screw hole, the adjustment plate moves downward until the flexible pad fits with the site to be compressed and hemostatic, and continues to move downward, so that the spring is slightly compressed to achieve preliminary compression hemostasis, and at this time, the airbag is squeezed to inject air into the compression airbag in the compression plate through the connecting tube, and the airbag is inflated to compress and stop the hemostasis, thereby achieving the purpose of convenient compression hemostasis for different patients and puncture sites, and solving the problem that most existing hemostat uses a fixing belt to fix it and then uses the airbag for compression hemostasis;

[0004] The above-mentioned device stops bleeding by controlling the flexible pad to press down during compression hemostasis. However, blood will stain the surface of the flexible pad during compression hemostasis. It needs to be disinfected after the hemostasis is completed, and the hemostatic device also needs to be disinfected before use. It is rather cumbersome before and after use. Therefore, an airbag compression hemostat is proposed. Utility Model Content

[0032] Example 2

[0033] like Figure 1-Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the lifting mechanism 3 includes a control plate 33, a support plate 34 is fixedly provided on the left side of the placement frame 1, a threaded rod 31 is fixedly provided on the top surface of the support plate 34, the top surface of the threaded rod 31 penetrates the bottom surface of the control plate 33 and extends to the top of the control plate 33, a nut 32 is rotatably provided on the top surface of the control plate 33 through a bearing seat, the inner side surface of the nut 32 is threadedly connected to the surface of the threaded rod 31, a dovetail groove is opened on the left side of the placement frame 1, a dovetail block 35 is slidably provided on the inner wall of the dovetail groove, and the left side of the dovetail block 35 is fixedly connected to the inner left end surface of the installation frame 21.

[0034] In this embodiment, the lifting mechanism 3 can be provided to adjust the arm according to the thickness of the patient's arm, so that the device is less restrictive during the hemostasis process, thereby making the device more effective during the hemostasis process.

[0035] When in use, the two sliding sleeves 219 are sleeved on the surfaces of the two sliding rails 218. When the two sliding sleeves 219 move, the hemostatic pad 212 can be driven to move, so that the hemostatic pad 212 can be located under the pressure plate 213. When the hemostatic pad 212 moves backward, the slot will also move. When the slot moves to the position of the insertion rod 222, the elastic sheet 220 can be used to move the insertion rod 222 upward, so that the hemostatic pad 212 can be fixed. When the patient's arm that needs compression and hemostasis is placed on the inner side of the placement frame 1, the two groups of springs 215 and two groups of dampers 216 can be used to make the two splints 23 close to each other during placement.

When the control plate 33 moves downward, the fixed frame 21 can be driven to move downward. When the fixed frame 21 moves downward, the hemostatic pad 212 can be driven to move synchronously. When the hemostatic pad 212 moves downward, it can be attached to the bleeding area. The elastic member 211 can squeeze the hemostatic pad 212 downward, so that the bleeding area of ​​the patient can be initially stopped. The squeezing airbag 24 can be expanded by pinching the control airbag 25, so that the hemostatic pad 212 can move downward. When the hemostatic pad 212 moves downward, the bleeding area of ​​the patient can be stopped, and the elastic member 211 can play a buffering role when the hemostatic pad 212 moves downward to avoid damage to the patient during the downward pressure process. After the hemostasis is completed, the mounting frame 21 is controlled to move upward, and the hemostatic pad 212 is manually controlled to move forward. Since the top of the insertion rod 222 is arc-shaped, the insertion rod 222 is disengaged from the slot when the hemostatic pad 212 is pulled with a little more force, and the hemostatic pad 212 can be removed.

[0036] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
