Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a brachial artery compressor. Background Technology

[0002] In clinical blood pressure measurement, the stethoscope is typically placed over the brachial artery pulsation area to obtain blood pressure data. The brachial artery is also involved in procedures such as upper limb angiography, certain interventional surgeries, or establishing vascular access. However, hemostasis is another challenge after brachial artery puncture. Similar to femoral artery puncture mentioned earlier, traditional manual compression hemostasis is inconvenient and requires a suitable compression device to ensure effective hemostasis and reduce complications.

[0003] In clinical use, current brachial artery compressors have the following drawbacks: Compression location: Due to individual differences, it is difficult to accurately locate the brachial artery puncture point, and it is prone to deviation. Compression intensity: It cannot be precisely adjusted according to the individual patient's condition, and it is easy to over- or under-compress, damaging tissue or causing bleeding or hematoma. Comfort: Hard materials or unreasonable design can lead to discomfort during prolonged use, affecting patient compliance.

[0004] How to provide a brachial artery compressor is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0023] Example 1

[0024] Combination Figures 1-2 As shown, a brachial artery compressor according to an embodiment of the present invention includes: an arm fixation assembly 1; the arm fixation strap includes a first Velcro 11, a second Velcro 12, and a fixation strap body 13; the fixation strap body 13 is Z-shaped and has an upper fixation edge and a lower fixation edge, which are parallel to each other; the first Velcro 11 has a first female surface and a first female surface; the second Velcro 12 has a second female surface and a second female surface; the first female surface is disposed on one side of the fixation strap body 13 and close to the upper fixation edge; the first female surface is disposed on the fixation strap body 13. On the other side of 3 and near the upper fixed edge, the second mother surface is provided on one side of the fixing belt 13 and near the lower fixed edge, and the second sub-surface is provided on the other side of the fixing belt 13 and near the lower fixed edge; the elbow limiter 2 includes a support belt 21, a support base 22 and a balloon, the support base 22 is fixedly connected to one side of the fixing belt 13 and located at the geometric center of the fixing belt 13, one end of the support belt 21 is movably connected to the center of the outer edge of the support base 22 and parallel to the upper fixed edge, and the balloon is provided on the support belt 21.

[0025] Specifically, this application provides a brachial artery compressor, including an arm fixation component 1 and an elbow limiter 2. Through the design of the arm fixation component 1 and the elbow limiter 2, when the patient places their arm into the arm fixation component 1, the balloon can be accurately positioned at the brachial artery puncture site via the fixation of the first Velcro 11 and the second Velcro 12, achieving precise compression and effectively reducing hemostasis failure or complications caused by inaccurate compression positioning. The balloon design allows medical personnel to precisely control the compression force according to the patient's specific condition. Injecting gas into the balloon avoids excessive or insufficient compression, improving hemostasis and safety. The Z-shaped fixation strap 13, the foam pad 222, and the ergonomic structural design improve the patient's comfort when wearing the compressor, facilitating postoperative recovery and cooperation with treatment. The balloon is placed on the support band 21. Combined with the stable connection structure between the support band 21 and the fixation band 13, it can maintain stable pressure during compression, avoiding changes in compression force due to slight movements of the patient. This achieves continuous, stable and precise compression hemostasis, improving the safety and effectiveness of hemostasis after brachial artery puncture.

[0026] In some possible implementations, the elbow limiter 2 also includes a limiting hook and loop fastener 24, which is disposed on the support band 21. The limiting hook and loop fastener 24 includes a limiting sub-surface and a limiting female-surface. The limiting female-surface is disposed on one side of the support band 21 and close to the other end of the support band 21, while the limiting sub-surface is disposed on the other side of the fixing band 13.

[0027] Specifically, after the support strap 21 is adjusted to a suitable position to limit the elbow, the limiting sub-face of the limiting Velcro 24 is attached to the corresponding limiting female face on the fixing strap body 13 to further enhance the fixing effect of the support strap 21.

[0028] In some possible implementations, the support belt 21 includes an arc-shaped support plate 211 and a flexible belt body 212. One end of the arc-shaped support plate 211 is movably connected to the center of the outer edge of the support base 22, and the other end of the arc-shaped support plate 211 is fixedly connected to one end of the flexible belt body 212. A limiting female surface is provided on one side of the flexible belt body 212 and close to the other end of the flexible belt body 212. The balloon is embedded in the arc-shaped support plate 211.

[0029] Specifically, the arc-shaped support plate 211 can better conform to the physiological curve of the elbow, making the pressure of the balloon 3 on the brachial artery more even. At the same time, the design of the flexible band 212 facilitates the adjustment and fixation of the support band 21, making the use of the entire elbow limiter 2 more convenient and flexible.

[0030] In some possible implementations, the balloon 3 includes an inflation valve 231, an indicator balloon 232, an inflation tube 233, and a multi-chamber balloon 234. The indicator balloon 232 is provided with an inflation valve 231 at one end, and the other end of the indicator balloon 232 is connected to one end of the inflation tube 233. The other end of the inflation tube 233 is connected to the interior of the multi-chamber balloon 234, and the multi-chamber balloon 234 is embedded in the arc-shaped support plate 211.

[0031] Specifically, medical staff can inflate the balloon 3 through the inflation valve 231 and visually judge the inflation volume based on the inflation level indicated by the balloon 232, thereby precisely controlling the pressure exerted by the balloon 3 on the brachial artery. The multi-chamber balloon 234 design makes the pressure distribution more uniform, avoiding damage to blood vessels and surrounding tissues caused by excessive local pressure, and can better adapt to different patients' vascular conditions and coagulation functions.

[0032] In some possible implementations, the support base 22 includes a U-shaped limiting piece 221, which is fixedly connected to one side of the fixing belt 13 and located at the geometric center of the fixing belt 13. A fixing center hole 4 is opened in the center of the U-shaped limiting piece 221.

[0033] Specifically, the U-shaped limiting piece 221 provides initial positioning and restraint for the elbow, making it easier to align the support band 21 and balloon with the brachial artery during installation and use, thus improving the accuracy and efficiency of compression. During the procedure, the patient's joint is placed into the central fixing hole 4, and the perforated roll is used to enclose the olecranon joint of the ulna, restricting the sliding or displacement of the brachial artery compressor. This results in better hemostasis through compression of the brachial artery.

[0034] In some possible implementations, the support base 22 includes a sponge pad 222, which is disposed on the U-shaped limiting piece 221. The arc-shaped support plate 211 is made of transparent PE material, and the support strip 21 and the upper fixed edge are parallel to each other.

[0035] Specifically, the sponge pad 222 increases the patient's comfort when their elbow contacts the support base 22, reducing discomfort caused by prolonged pressure. The curved support plate 211 made of transparent PE material allows medical staff to easily observe the puncture site.
