Description

Technical Field

[0001] This invention relates to the field of radial artery compression technology, specifically a radial artery compression device for cardiology nursing. Background Technology

[0002] Radial artery compressors are commonly used disposable medical hemostatic devices in interventional departments, primarily for hemostasis at wrist puncture sites after coronary angiography, radial artery stent implantation, arterial blood sampling, and invasive blood pressure monitoring. These devices are mainly divided into two types: balloon-type and knob-type mechanical type. They consist of a flexible wristband, pressure adjustment components, and a compression pad, featuring a simple structure and a comfortable fit.

[0003] For example, a radial artery compressor with publication number CN108742759A uses a timing compression system added to the base to control the position of the slider using a timing module. When the preset time is reached, the compressor's driver controls the slider to separate from the locking block, causing the slider to automatically spring upward, lifting the pressure plate and adjusting screw together. The pressure plate no longer compresses the artery, achieving the purpose of automatic control and reducing the labor intensity of medical staff. However, radial artery compression requires continuous compression for about 10 hours. Prolonged local continuous pressure can lead to skin ischemia and necrosis, especially in the elderly, diabetic patients, and patients with low protein levels. In addition, the wristband is not breathable and is wrapped for a long time, which can easily lead to sweating and dampness of the skin, causing rashes, itching, and erosion. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a radial artery compression device for cardiology nursing.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a radial artery compressor for cardiology nursing, including a rubber band, a fixing frame fixedly connected to the upper end of the rubber band, a groove opened on the lower surface of the fixing frame, a compression component for compressing the radial artery disposed inside the groove, a pressure regulating component for adjusting the pressure of the compression component disposed at the upper end of the compression component, and a tightening component for adjusting the length of the rubber band disposed at the lower end of the rubber band. The extrusion assembly includes an annular airbag, which is fixedly connected inside the groove. A fixing plate is fixedly connected to the bottom of the annular airbag. A spiral hose is embedded on the lower surface of the fixing plate. A plug connector is fixedly connected to the other end of the spiral hose. A syringe is inserted into the other end of the plug connector. A spiral channel is formed between the lower outer wall of the spiral hose and the lower surface of the fixing plate.

[0006] Specifically, the syringe is filled with cold water at a temperature of 10-15 degrees Celsius.

[0007] Specifically, a circular block is fixedly fitted inside the annular airbag, and a baffle is fixedly connected to the upper end of the circular block.

[0008] Specifically, the upper surface of the annular airbag is fixedly connected to the inner wall of the groove, and the outer circular sidewall of the annular airbag is in contact with the inner sidewall of the groove.

[0009] Specifically, the pressure regulating component includes a connecting pipe and an embedded hole. The connecting pipe is embedded on the upper surface of the annular airbag, and the embedded hole is opened on the inner wall of the upper surface of the fixed frame. The upper end of the connecting pipe is embedded inside the embedded hole, and the other end of the connecting pipe is fixedly connected to an inflatable airbag. The other end of the inflatable airbag is fixedly connected to an air valve.

[0010] Specifically, the retracting assembly includes a fixing plate, which is embedded in the lower outer wall of the rubber strip. The lower end of the fixing plate has an insertion hole.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 7 The present invention provides the following technical solutions: Example 1: A radial artery compression device for cardiology nursing includes a rubber band 1, a fixing frame 2 fixedly connected to the upper end of the rubber band 1, a groove 3 formed on the lower surface of the fixing frame 2, a compression component 4 for compressing the radial artery is provided inside the groove 3, a pressure regulating component 5 for adjusting the pressure of the compression component 4 is provided at the upper end of the compression component 4, and a tightening component 6 for adjusting the length of the rubber band 1 is provided at the lower end of the rubber band 1.

[0018] The compression assembly 4 includes an annular airbag 41, which is fixedly connected inside the groove 3. A fixing plate 42 is fixedly connected to the bottom of the annular airbag 41. A spiral tube 43 is embedded in the lower surface of the fixing plate 42. A plug connector 44 is fixedly connected to the other end of the spiral tube 43. A syringe 45 is plugged into the other end of the plug connector 44. A spiral channel 46 is formed between the lower outer wall of the spiral tube 43 and the lower surface of the fixing plate 42. The annular airbag 41 achieves uniform pressure on the puncture point. The spiral tube 43, in conjunction with cold water, achieves local cold compress, reduces skin temperature, reduces sweating and inflammatory response, and avoids skin ischemia, necrosis, and moist erosion caused by prolonged pressure.

[0019] The syringe 45 is filled with cold water at a temperature of 10-15 degrees Celsius. This temperature range allows for safe cold compresses, achieving the effects of cooling, stopping bleeding, and soothing the skin without causing local frostbite.

[0020] A circular block 47 is fixedly fitted inside the annular airbag 41. A baffle 48 is fixedly connected to the upper end of the circular block 47. The circular block 47 and the baffle 48 cooperate to limit the excessive expansion of the annular airbag 41, ensuring accurate compression position and stable pressure, and avoiding displacement or excessive pressure that could damage blood vessels.

[0021] The upper surface of the annular airbag 41 is fixedly connected to the inner wall of the groove 3, and the outer circular sidewall of the annular airbag 41 is in contact with the inner sidewall of the groove 3, which improves the installation stability of the annular airbag 41, prevents displacement during use, and ensures continuous and reliable compression effect.

[0022] In use, wrap the rubber band 1 around the patient's wrist, align the compression component 4 below the fixation frame 2 with the radial artery puncture point, connect the syringe 45 to the spiral tubing 43 via the connector 44, and push the syringe 45 to inject 10-15 degree Celsius cold water into the spiral tubing 43. The cold water flows along the spiral tubing 43, providing a cold compress to the puncture point and surrounding skin to lower its temperature. At the same time, the cold water supports the spiral tubing 43, which in turn supports the fixation plate 42 and the wearer's skin, creating a spiral channel 46 by dividing the gap. External air enters the gap between the annular airbag 41 and the skin through the spiral channel 46, allowing the wearer's skin to breathe. This effectively reduces local skin temperature and sweating, preventing skin ischemia, necrosis, rashes, itching, and erosion caused by prolonged pressure. The circular block 47 and baffle 48 inside the annular airbag 41 limit the airbag's expansion range, ensuring precise pressure positioning and preventing excessive pressure from damaging blood vessels. At the same time, the annular airbag 41 fits tightly with the groove 3 to prevent displacement during use, achieving continuous and stable pressure for hemostasis and cold compress care.

[0023] Example 2: The technical solution of this example that differs from that of Example 1 includes: the pressure regulating component 5 includes a connecting pipe 51 and an embedded hole 52. The connecting pipe 51 is embedded on the upper surface of the annular airbag 41, and the embedded hole 52 is opened on the inner wall of the upper surface of the fixed frame 2. The upper end of the connecting pipe 51 is embedded in the embedded hole 52, and the other end of the connecting pipe 51 is fixedly connected to an inflatable airbag 53. The other end of the inflatable airbag 53 is fixedly connected to an air valve 54.

[0024] When in use, press the inflatable balloon 53, and gas enters the annular balloon 41 through the connecting tube 51, causing the balloon to expand and adjust the pressure. After reaching the appropriate pressure, close the air valve 54 to maintain the pressure. When it is necessary to reduce the pressure in the later stage of hemostasis, open the air valve 54 to slowly release the pressure. The entire process does not require disassembling the compressor, making it simple to operate and suitable for patients' hemostasis needs at different stages.

[0025] Example 3: The technical solution of this example, which differs from that of Example 2, includes: the gathering component 6 includes a fixing piece 61, which is embedded in the lower outer wall of the rubber strip 1. The lower end of the fixing piece 61 has an insertion hole 62. A rubber strip 63 is fixedly connected to the lower outer wall of the rubber strip 1. The rubber strip 63 is inserted into the insertion hole 62. A fixing protrusion 64 is fixedly connected to the lower outer wall of the rubber strip 1. A plurality of snap-fit ​​grooves 65 are opened on the inner wall of the rubber strip 63. The fixing protrusion 64 snaps into the snap-fit ​​grooves 65.

[0026] When in use, insert the rubber strip 63 into the insertion hole 62 of the fixing plate 61. Depending on the thickness of the patient's wrist, pull the rubber strip 63 so that the fixing protrusion 64 is engaged in the corresponding locking groove 65 to complete the length fixation of the rubber strip 1. The tightness can be flexibly adjusted to ensure that the compression device is worn securely, while avoiding excessive tightness that may affect blood circulation in the wrist, thus improving wearing comfort and applicability.
