Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a distal radial artery pressure hemostat after interventional procedures. Background Technology

[0002] The distal radial artery pressure hemostat is a medical device specifically designed to apply pressure to the puncture site for hemostasis after interventional procedures via the distal radial artery. It helps close the arterial puncture site by applying controllable pressure, preventing bleeding or hematoma formation. It achieves rapid and stable hemostasis by compressing the puncture site with a balloon. Using the hemostat allows for uniform and adjustable pressure, giving patients more freedom of movement and significantly improving comfort.

[0003] A search revealed Chinese Patent Publication No. CN220158318U, which discloses a distal radial artery pressure hemostat. This device features a dustproof structure and a pressure mechanism that uses an air bladder to deliver air through a pressure tube to an inflation valve. The sealing ring inside the inflation valve is ruptured, and the air is then directed to a retaining ring, which in turn directs the air to a filter screen. Finally, the air enters the wristband, causing it to expand and achieve pressure hemostasis. A warning device is included to keep track of when the device is worn, preventing prolonged wear that could lead to poor blood circulation and necrosis. The pressure tube and inflation valve are connected by threads and can be easily disassembled.

[0004] In the above technical solutions, the dustproof structure avoids the phenomenon of blood circulation failure caused by prolonged wearing time. However, hemostatic devices usually need to be worn for a certain period of time. The lack of limiting function of the hemostatic device can cause displacement due to movement or accidental touch during the wearing process, thereby reducing the hemostatic effect of the hemostatic device. Therefore, a distal radial artery pressure hemostatic device after interventional surgery is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a distal radial artery pressure hemostat after interventional procedures, which aims to improve the problem that the lack of limiting function in the existing distal radial artery pressure hemostat after interventional procedures leads to the risk of displacement due to movement or accidental contact during the wearing of the hemostat.

A three-way inflation port 4 is fixedly connected to the end of the connecting tube 3. An air inflator 5 is inserted into the inner wall of the three-way inflation port 4. The surface of the air inflator 5 is marked with graduations. This allows medical staff to perform inflation and deflation operations intuitively and accurately. The air syringe 5 transmits air through the three-way inflation port 4 to the inside of the connecting tube 3. The air bladder 2 contacts the puncture site, and after the air bladder 2 inflates, it compresses the puncture site to achieve hemostasis. The surface of the three-way inflation port 4 is equipped with a fingertip indicator 6. A soft magnetic sheet 7 is fixedly connected to the outer wall of the wristband 1. A soft magnetic sheet 9 is magnetically connected to the outer wall of the soft magnetic sheet 7. There are two sets of soft magnetic sheets 7 and two sets of soft magnetic sheets 9, and each set is positioned in pairs. The U-shaped frame 8 is fixedly connected to the outer wall of the soft magnetic sheet 2 9 on the inner and outer surfaces of the wristband 1 and the upper and lower sides of the inside of the U-shaped frame 8. The U-shaped frame 8 is made of plastic and can reduce the overall weight when fixed to the wristband 1, so that the patient can reduce the weight on the wrist during the wearing time. The outer wall of the U-shaped frame 8 is fixedly connected to the male side of the Velcro 10 and the female side of the Velcro 11. The bottom of the U-shaped frame 8 has a storage groove 12, and the inner wall of the storage groove 12 is rotatably connected to the roller 13. A connecting rope 15 is fixedly connected to the outer wall of the device. A middle finger loop 16 is fixedly connected to the outer wall of the connecting rope 15. The middle finger loop 16 is used to put on the patient's middle finger. An elastic rope 17 is fixedly connected to the outer wall of the connecting rope 15. A thumb loop 18 is fixedly connected to the end of the elastic rope 17. The thumb loop 18 is put on the patient's thumb. A coil spring 14 is fixedly connected to the outer wall of the drum 13. The coil spring 14 can provide a certain degree of tension limit to the connecting rope 15 and help the connecting rope 15 to automatically rewind through its elasticity.

[0020] Reference Figures 4-6The U-shaped frame 8 is fitted onto the outer wall of the wristband 1, the connecting rope 15 is wound around the outer wall of the drum 13, the fixed end of the coil spring 14 is fixedly connected to the inner wall of the storage groove 12, the outer wall of the U-shaped frame 8 is provided with a limiting hole 19, the limiting hole 19 is fitted onto the outer wall of the connecting rope 15, the center of the hook and loop fastener male face 10 is set with an opening, the opening of the hook and loop fastener male face 10 is to avoid the connecting rope 15 extending from the limiting hole 19, the hook and loop fastener female face 11 is provided with two sets, which are symmetrically arranged with the center point of the limiting hole 19 as the axis of symmetry.

[0021] Reference Figures 5-6 The top of the U-shaped frame 8 is equipped with nano double-sided adhesive 20, which can firmly stick to the U-shaped frame 8 to fix the sponge pad 21. The adhesive leaves no residue when it is removed, making it easy to replace the sponge pad 21. The sponge pad 21 contacts the outside of the wrist, avoiding direct contact between the U-shaped frame 8 and the sponge pad 21, thus ensuring the comfort of hemostasis. The top of the nano double-sided adhesive 20 is fixedly connected to the sponge pad 21. The top of the sponge pad 21 is concave, and the bottom of the sponge pad 21 is in contact with the inner surface of the wristband 1. The top of the sponge pad 21 is fixedly connected to the anti-slip ridge 22, which is made of soft anti-slip material such as silicone, to increase the friction resistance when the sponge pad 21 contacts the skin.

[0022] Working principle: The U-shaped frame 8 is placed on the wristband 1. The magnetic attraction between the first and second soft magnetic sheets 7 and 9 fixes the U-shaped frame 8 to the wristband 1. Then, the male and female sides of the Velcro 10 and 11 are glued together to further secure the U-shaped frame 8 and prevent it from falling off. The puncture point sheath is then pulled out a certain distance, and the wristband 1 is placed on the wrist to ensure that the airbag 2 is in contact with the puncture point. The Velcro of the wristband 1 is used to fix the wristband 1. The middle finger ring 16 is manually pulled outward. The connecting rope 15 drives the drum 13 to rotate in the storage slot 12, and the coil spring 14 is stretched accordingly, allowing the connecting rope 15 to put the middle finger ring 16 on the patient's middle finger from the back of the hand. The thumb ring 18 is put on the patient's thumb by the elasticity of the elastic rope 17. Wearing the middle finger ring 16 and the thumb ring 18 will not cause discomfort to the patient's hand. To prevent the wristband from being affected by movement, after the wristband 1 is fixed, the air syringe 5 is inserted into the three-way inflation port 4 to inflate the air bag 2. The air is inflated according to the scale marks on the surface of the air syringe 5. After the air bag 2 expands, it applies pressure to the puncture point. Then the sheath is completely pulled out. The medical staff touches the distal radial artery pulse of the patient and observes whether there is bleeding at the puncture point. Two minutes later, the prescribed amount of air is released using the air syringe 5. The radial artery pulse is touched again to observe whether there is bleeding at the puncture point. After the patient returns to the ward, the prescribed amount of air is released every two hours until the deflation is completed. During the process of the patient wearing the wristband 1, the middle finger ring 16 and the thumb ring 18 provide a certain degree of limitation for the wristband 1 to prevent the wristband 1 from shifting when the patient moves, thereby ensuring the hemostasis effect.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
