Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, more particularly, it relates to a pressure cold therapy device for treating forearm swelling after transradial intervention. BACKGROUND

[0002] Clinically, coronary angiography intervention treatment is often performed through upper limb radial artery puncture, and various factors can cause postoperative forearm swelling. Studies have analyzed the causes of swelling as follows: first, from the perspective of anatomy, the hand is far away from the heart, the local blood circulation and metabolism are slow, and the phenomenon of excessive retention of liquid in the extracellular tissue space or body cavity can occur, thereby causing forearm swelling; second, from the perspective of the operation itself, the following reasons are included: ① Intraoperative radial artery puncture is not smooth, repeated puncture and multiple penetrating puncture cause swelling; ② Intraoperative improper operation causes reverse damage to the radial artery or small branch rupture caused by the guide wire and catheter, thereby causing swelling; ③ Postoperative improper compression of the artery compression hemostat and improper wrist fixation cause swelling; ④ A large amount of anticoagulant and antithrombotic drugs are used during the perioperative period, which causes swelling. According to the literature, the incidence of postoperative forearm hematoma is as high as 5.85%, which often leads to serious consequences such as increased tension of the patient's forearm, pain, limited activity, etc.

[0003] At present, the following methods are commonly used in clinical practice to deal with this situation: ① Ice bag external application; ② Puncture limb bandage compression dressing; ③ Patient self-elevate the operation limb, etc. However, there are also the following problems corresponding to them: First, ice bag external application cannot accurately control the temperature, and the ice bag cannot be tightly attached to the skin surface, cannot be fixed, and the conventional ice bag has a hard texture, which often causes discomfort to the patient during ice application, often resulting in unsatisfactory ice application effect; second, the pressure of the puncture limb bandage compression dressing method cannot be accurately controlled, and too loose cannot achieve the compression effect, and too tight often causes pain and discomfort to the patient; in addition, the patient is often tired due to prolonged elevation, resulting in poor compliance. If the forearm swelling cannot be properly treated, obvious ecchymosis and blister formation of the affected limb can be seen, and more serious cases can even develop into osteofascial compartment syndrome, which is often manifested by the following five symptoms: ① Pain or pain turning into painlessness; ② Pale; ③ No pulse; ④ Paralysis; ⑤ Paresthesia, which requires surgical incision of the fascia for decompression to prevent ischemic necrosis of the muscle and nerve. If the patient has obvious symptoms of the above five symptoms, it often indicates that the best treatment opportunity has been missed, which can lead to limb disability or even amputation and other serious consequences. The above adverse consequences after radial artery puncture intervention not only increase the pain, infection and disability risk of the patient, but also increase the medical expenses and prolong the hospitalization time of the patient.

[0004] Furthermore, the EASY grading and treatment guidelines for hematoma after percutaneous radioulnar PCI published in the journal *Circulation* indicate that applying pressure, ice, and elevating the operated limb at 45°–60° can effectively alleviate forearm swelling following coronary intervention. Studies have also shown that applying pressure 10-20 mmHg higher than the patient's systolic blood pressure (1 mmHg = 0.133 kPa) is more effective for hemostasis and swelling reduction in patients with post-interventional forearm hematoma. Currently, the clinically used methods of pressure bandaging and external ice pack application are ineffective in relieving forearm swelling, and the two methods cannot be applied simultaneously. Applying ice close to the skin prevents pressure bandaging, while applying ice packs simultaneously with pressure bandaging does not adhere to the skin surface, failing to reach the required temperature for ice application, resulting in poor swelling relief. Additionally, bandaging makes it impossible to observe the color of the swollen skin. Furthermore, patient compliance with instructions to elevate the operated limb is poor.

[0005] Therefore, there is an urgent need for more suitable methods to alleviate the swelling in patients' forearms. Utility Model Content

[0006] The purpose of this invention is to provide a pressure cryotherapy device for relieving forearm swelling in patients. This pressure cryotherapy device is designed to treat forearm swelling following radial artery intervention. It uses a double-layered transparent air cuff to continuously apply pressure to the swollen area of ​​the patient's forearm and elevates the limb to promote blood flow. Additionally, the air cuff contains a polymer hydrogel cryotherapy patch that adheres closely to the skin surface, providing cooling, pain relief, and hemostasis.

[0007] This application provides a pressure cryotherapy device for treating forearm swelling following radial artery intervention, comprising:

[0008] An arm lifter is used to elevate the patient's forearm.

[0009] An air-filled cuff, mounted on the elevation support, is used to secure the patient's forearm; and

[0010] A connector for detachably connecting the lifting support and the airbag cuff.

[0011] Furthermore, the elevation support includes an upper arm placement part and a forearm cuff placement part, the upper arm placement part being used to elevate the patient's upper arm, and the forearm cuff placement part being used to fix the airbag cuff.

[0012] Furthermore, the lifting support is an inflatable support structure, and the side wall of the lifting support is provided with an air inlet, and the air inlet is provided with an airtight check valve and an air nozzle cap.

[0013] Further, the air bag sleeve belt is an inflatable pressurized structure, and a connecting pipe is arranged in communication with the air bag sleeve belt.

[0014] Further, the air bag sleeve belt is further provided with an inflation pressure setting knob, and the inflation pressure setting knob contains a control chip, a pressure sensor and a proportional valve, so as to realize continuous pressure control.

[0015] Further, the air bag sleeve belt is provided as a transparent air bag.

[0017] Further, the connecting piece includes a first connecting piece arranged on the lifting support and a second connecting piece arranged on the air bag sleeve belt, and the first connecting piece and the second connecting piece are detachably matched.

[0018] The device can inject pressure into the air bag sleeve belt and the lifting support through the inflation pump, inject appropriate gas into the lifting support to a suitable height, remove the inflation pump after inflation, pop out the air cap, and the original injected gas does not escape due to the design of the air-tight check valve. Connect the inflation pump connecting pipe with the air bag sleeve belt, rotate the pressure control button according to the patient's preoperative blood pressure by injecting gas, and the pressure control button contains a control chip, a pressure sensor and a proportional valve, which can control the pressurization pressure to be maintained at 10-20mmHg higher than the patient's systolic pressure. After the lifting support is filled with gas, the patient can place the sleeve belt in the lifting support and fix it with the buckle to realize the lifting of the limb. If you need to get out of bed, you can separate the lifting support and the air bag sleeve belt by unfastening the buckle. In addition, the sleeve belt is attached with a high molecular water gel cold therapy patch to cool, relieve pain and stop bleeding. The cold compress effect lasts for a long time, and the cold therapy patch can be freely removed when not in use or replaced.

[0019] In summary, the pressure cold therapy device for treating forearm swelling after radial artery intervention of the present application can perform cold therapy while closely adhering to the skin, and can also perform pressurized bandaging and limb lifting.
