Abstract
Description
Technical Field

[0002] In the medical field, the brachial artery, as the main blood supply artery to the forearm and hand, is of self-evident importance. Brachial artery puncture is a common procedure in medical procedures such as hemodialysis, angiography, and arterial blood sampling. However, effective hemostasis after puncture has become a challenge. Currently, traditional hemostasis methods, such as direct manual compression or the use of simple bandages, often find it difficult to ensure the stability and continuity of pressure. Especially when the patient moves the elbow joint, the compression point is easily displaced, resulting in poor hemostasis and may even cause bleeding complications. In addition, long-term manual compression not only increases the workload of medical staff, but may also cause discomfort to patients and affect their postoperative recovery. More seriously, unstable compression may cause blood to penetrate into surrounding tissues, causing local swelling and pain, and may even damage adjacent nerve and vascular structures.

When the utility model is used, it can not only compress the patient's brachial artery puncture point to stop bleeding, and automatically inflate and discharge gas, but also limit the patient's elbow joint activity to prevent the pressure point from shifting, which can effectively reduce the workload of medical staff. To bear the burden and ensure the hemostatic effect, the compression airbag 3 is arranged on the inner wall of the plate body 1 4 near the rotation connection, and the bandage 6 is arranged on the outer wall of the plate body 1 4 and the plate body 2 5 away from the rotation connection. By setting the compression airbag 3 on the inner wall of the plate body 1 4 near the rotation connection, it is convenient for the patient's elbow joint to be located at the rotation connection between the plate body 1 4 and the plate body 2 5. The compression airbag 3 can cover the brachial artery puncture point on the elbow fossa for compression and hemostasis. By setting up the bandage 6, it is convenient to surround the patient's arm so as to fix the first splint 1 and the second splint 2. A Velcro 9 is provided at the edge of the inner wall of one end of the compression airbag 3, and an adhesive layer 8 is provided on the outer wall of the other end, and the Velcro 9 and the adhesive layer 8 are bonded together.

The inner wall edge of the movable end of the strap 6 is provided with a Velcro 2 10, and the outer wall of the strap 6 is provided with an adhesive layer 2 11, and the Velcro 2 10 and the adhesive layer 2 11 are bonded. After the patient's arm is surrounded by the strap 6 through the perforation 23 of the fixing frame 22, it is only necessary to adhere the Velcro 2 10 to the adhesive layer 2 11 at a suitable distance, that is, the first splint 1 and the second splint 2 are completed. After the combination connection is completed, the patient's arm can be clamped and fixed. The installation box 7 is provided on the outer wall of the plate body 1 4 corresponding to the setting position of the compression airbag 3, and the operation panel 12 is provided at the other end of the installation box 7 away from the plate body 1 4.The operation panel 12, micro air pump 14, lithium battery 15, timing module 16 and air pressure sensor 18 are all electrically connected to the microprocessor 13.

After receiving the instruction, the microprocessor 13 controls the micro air pump 14 to inflate the compression air bag 3 and stops after reaching the preset pressure. The air pressure sensor 18 monitors the pressure in the compression air bag 3 in real time and adjusts the micro air pump 14 to maintain the pressure when necessary. The pressure is stable, and the timing module 16 can be set to automatically charge and discharge air cycles as needed, or automatically stop charging after the set time is reached. The lithium battery 15 provides power for the entire system and is charged through the charging port. After the external charging device is connected to the charging port, the lithium battery 15 can be charged with electric energy so that the lithium battery 15 can power various electrical components. The anti-slip rubber pad 19 is set on the inner wall of the plate body 1 4 and the plate body 2 5 of the first splint 1, as well as on the inner wall of the main body 20 and the auxiliary plate body 21 of the second splint 2, and the anti-slip rubber pad 19 is soft and elastic. Through the establishment of the anti-slip rubber pad 19, the anti-slip rubber pad 19 is made of soft and elastic silicone material. When the first splint 1 and the second splint 2 clamp and fix the patient's arm, the anti-slip rubber pad 19 can not only increase the patient's comfort during clamping and fixation, but also increase the friction coefficient to prevent the first splint 1 and the second splint 2 from sliding and displacing as the patient moves, which affects the effectiveness of the compression airbag 3 fixation. The two side edges of the outer wall of the two sub-plate bodies 21 are both provided with fixing frames 22, and each fixing frame 22 is provided with a number of through-holes 23. Through the opening of the several through-holes 23 on the fixing frames 22, for the patient whose arm can be straightened, the first splint 1 and the second splint 2 are horizontally clamped on both sides of the patient's arm, and the strap 6 can be moved from the same position The through-holes 23 are passed through for encircling fixation. For patients who cannot straighten their hands, the use angles of the plates 1 4 and 2 5 and the use angles of the sub-plates 21 on both sides of the main plate 20 are adjusted to adapt to the curvature of the patient's arm. When the bandage 6 fits the patient's arm, the through-holes 23 at the same position as in the initial state are intertwined. The bandage 6 passes through the through-holes 23 at the appropriate position for encircling fixation. In the state of encircling fixation through the through-holes 23, the through-holes 23 can limit the range of movement of the bandage 6 passing therethrough, preventing the bandage 6 from slipping on the first splint 1 and affecting the effectiveness of the clamping and fixation between the first splint 1 and the second splint 2.
[0035] The working principle of the present invention is as follows: by disposing the compression airbag 3 on the inner wall of the rotational connection of the plate body 1 4, it is convenient for the patient's elbow joint to be located at the rotational connection between the plate body 1 4 and the plate body 2 5, and the compression airbag 3 can cover the brachial artery puncture point on the elbow fossa. When the compression airbag 3 covers the brachial artery puncture point, the Velcro 1 9 is adhered to the adhesive layer 1 8 at a suitable distance, and the compression airbag 3 can complete the surrounding and fixing operation of the patient's arm. At this time, when the first splint 1 and the second splint 2 are used to clamp and fix the patient's arm, for the patient whose arm can be straightened, the first splint 1 and the second splint 2 are clamped horizontally relative to each other on both sides of the patient's arm, and the strap 6 can be inserted from the perforations 23 at the same position. The strap 6 is passed through the through-holes 23 at the appropriate position for encircling and fixing, and for patients whose hands cannot be straightened, the use angles of the plate 1 4 and the plate 2 5 and the use angles of the auxiliary plates 21 on both sides of the main plate 20 are adjusted to adapt to the curvature of the patient's arm and fit the patient's arm. When the through-holes 23 at the same position as the initial state are staggered, the strap 6 can pass through the through-holes 23 at the appropriate position for encircling and fixing, and when the strap 6 passes through the through-holes 23 for encircling and fixing, the through-holes 23 can limit the range of movement of the strap 6 passing therethrough, preventing the strap 6 from slipping on the first splint 1 and affecting the effectiveness of the clamping and fixing of the first splint 1 and the second splint 2. 3 After wrapping the patient's arm, it is only necessary to stick the Velcro 2 10 on the adhesive layer 2 11 at an appropriate distance, and the first splint 1 and the second splint 2 can be combined and connected to clamp and fix the patient's arm. The compression airbag 3 is covered and wrapped around the patient's brachial artery puncture point. After the first splint 1 and the second splint 2 clamp and fix the patient's arm, the medical staff only needs to press the operation button on the operation panel 12 to set the required pressure value and duration. After receiving the instruction, the microprocessor 13 controls the micro air pump 14 to inflate the compression airbag 3 and stops after reaching the preset pressure. The air pressure sensor 18 monitors the pressure in the compression airbag 3 in real time and adjusts the micro air pump 1 through the microprocessor 13 when necessary. 4 works to maintain pressure stability. The timing module 16 can be set to automatically charge and discharge air cycles as needed, or automatically stop charging after the set time is reached. After the external charging device is connected to the charging port, it can charge electric energy into the lithium battery 15 so that the lithium battery 15 can power various electrical components. Through the establishment of the anti-slip rubber pad 19, and the anti-slip rubber pad 19 is made of soft and elastic silicone material, when the first splint 1 and the second splint 2 clamp and fix the patient's arm, the anti-slip rubber pad 19 can not only increase the patient's comfort during clamping and fixation, but also increase the friction coefficient to prevent the first splint 1 and the second splint 2 from sliding and displacing with the patient's activities, which affects the effectiveness of the compression airbag 3.
