Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a device for preventing forearm osteofascial syndrome after radial artery puncture. Background Technology

[0002] Radial artery puncture angiography is a non-surgical, minimally invasive diagnostic and treatment method. After years of clinical practice, it has proven to be minimally invasive, less painful, easier to control hemorrhage, faster recovery, fewer complications at the puncture site, and no restriction on postoperative activity. Forearm hematomas caused by radial artery puncture are often due to the patient's own small or malformed radial artery, repeated punctures during the procedure, damage to the vessel due to the puncture guidewire or catheter, improper postoperative hemostasis, postoperative anticoagulant use, and limb movement. Currently, after a hematoma appears, only gauze rolls or bandages can be used for pressure application, with limited effectiveness. Enlargement of upper limb hematomas can lead to increased pressure within the osteofascial compartment, resulting in osteofascial syndrome. This syndrome manifests as pain, pallor, pulselessness, numbness, and paresthesia in the operated limb. According to currently available information, the incidence of forearm hematomas is approximately between 0.9% and 13.9%. Compartmental syndrome caused by hematoma is rare, with previously reported incidence rates of 0.004%-0.02%. However, if it occurs and is not diagnosed and treated promptly, it can lead to limb injury, disability, or even amputation. In their article "Prevention and Treatment of Compartmental Syndrome after Radial Coronary Intervention," Professors Xu Yi and Yang Yuejin discuss the effectiveness of non-surgical treatments for compartmental syndrome after radial artery puncture. They specifically mention Hahalis's experience, which involves using an inflatable cuff to continuously compress the affected limb at a pressure lower than systolic blood pressure for 15 minutes, twice per hour, which can help prevent disease progression. They also cite a case of a patient with compartmental syndrome who recovered after conservative treatment using this method.

[0003] Therefore, in order to prevent the occurrence of osteofascial syndrome after radial artery puncture, it is urgent to develop an effective prevention and treatment measure to improve postoperative forearm hematoma and reduce the risk of postoperative upper limb osteofascial syndrome. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies and provide a device for preventing forearm osteofascial syndrome after radial artery puncture. By applying pressure to the forearm hematoma with an airbag, it achieves hemostasis and massages the hematoma to soften and dissipate it, thereby preventing the formation of osteofascial syndrome.

[0005] To achieve the above objectives, this utility model provides a device for preventing forearm osteofascial syndrome after radial artery puncture, comprising an air cuff body, a support plate, magnetic balls, and an inflation pump. The air cuff body has several strip-shaped independent air bladders evenly distributed along its width. Each independent air bladder is lined with a support plate, and a row of magnetic balls is embedded radially on the support plate. Each independent air bladder has an inflation port and is connected to the inflation pump via a venting tube. Each independent air bladder has a deflation plug, and Velcro straps are provided on the outer sides of the independent air bladders at both ends of the air cuff body.

[0006] Furthermore, the number of independent airbags in the airbag cuff body is 6-10.

[0007] Furthermore, the airbag cuff body is made of soft fabric or vinyl material.

[0008] Furthermore, the airbag cuff body is 20 cm-30 cm long and 30 cm wide, with the independent airbag placed within 20 cm of the total length of the airbag cuff body.

[0009] Furthermore, the inflation port of the independent airbag is equipped with a one-way valve.

[0010] Furthermore, the independent airbag has a width of 2cm and a length of 20cm.

[0011] Furthermore, the support plate is made of aluminum or plastic.

[0012] Furthermore, the length × width × thickness of the support plate is 20cm × 2cm × 0.2cm.

[0013] Furthermore, the number of magnetic balls is 6-8, the diameter of the magnetic balls is 3mm-5mm, and they are evenly embedded in the middle of the support plate.

[0014] Furthermore, the air pump is a mechanical air pump, which is equipped with a timer knob, a pressure knob, and a mode knob.

[0015] Beneficial effects: Compared with the prior art, this utility model achieves hemostasis and massage of the hematoma by applying pressure to the forearm with an airbag. Through the alternating pressure of the airbag and the alternating compression of the inner magnetic ball on the forearm, the blood stasis is dispersed and the swelling is reduced, ensuring blood supply to the fingertips, softening and dissipating the hematoma, and preventing the formation of osteofascial syndrome.

[0031] Design Principles

[0032] The inflatable airbag set can wrap around the forearm (similar to an extended blood pressure monitor cuff). A complete circle can be designed with 6-10 airbags and a support plate. Through the alternating pressure of the airbags, the magnetic balls inside alternately compress the forearm, promoting the dispersion of blood stasis and reducing swelling, ensuring blood supply to the fingertips, and alleviating pain in the affected limb. Compression of the hematoma is the key to its effectiveness. The small magnetic balls, aided by the force of the airbags, provide point pressure.

[0033] Work process

[0034] 1. If a forearm hematoma occurs after radial artery puncture, first measure the patient's blood pressure in the operated limb;

[0035] 2. Select an appropriate length of air cuff based on the patient's forearm circumference. Wrap the air cuff around the patient's forearm with the magnetic ball side facing inwards, and secure it at both ends with Velcro.

[0036] 3. Using the pressure knob on the air pump, select a pressure 5-10 mmHg lower than the patient's pressure. Using the timer knob, select 3 minutes per inflation cycle. Using the mode knob, select alternating inflation. Then press the start button to begin treatment. Alternatively, using the pressure knob on the air pump, select a pressure 5-10 mmHg lower than the patient's pressure. Using the timer knob, select 3 minutes per inflation cycle with a 30-second interval between each inflation. Using the mode knob, select full inflation of all airbags. Then press the start button to begin treatment.

[0037] 4. By using different inflation / deflation modes, pressure can be better penetrated into the subcutaneous muscle layer, preventing ischemia of the operated limb and increasing patient comfort. The total treatment time depends on the severity of the postoperative hematoma, and 4-8 hours is recommended.

Therefore, variations and modifications without departing from the overall concept of this utility model should be within the protection scope of this utility model.
