Description

Technical Field

[0001] The present application relates to the field of medical devices, and more specifically, to a pressure cold therapy device for treating forearm swelling complicated by transradial artery intervention. Background Art

[0002] In clinical practice, interventional coronary angiography is often performed through the radial artery of the upper limb. A variety of factors may cause postoperative forearm swelling. Studies have analyzed the causes of swelling as follows: First, from an anatomical point of view, the hand is far from the heart, and the local blood circulation and metabolism are slow, which can cause excessive fluid retention in the extravascular and extracellular tissue spaces or body cavities, thereby causing forearm swelling; second, from the perspective of the surgery itself, there are several reasons: ① Swelling caused by unsmooth radial artery puncture, repeated punctures, and multiple penetrating punctures during surgery; ② Improper operation during surgery causes retrograde damage to the radial artery or rupture of small branches caused by guidewires and catheters, causing swelling; ③ Improper compression of the arterial compression hemostat and improper wrist immobilization after surgery cause swelling; ④ Swelling caused by the large-scale use of anticoagulants and antithrombotic drugs during the perioperative period. 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 forearm tension, pain, and limited activity in patients.

[0003] At present, the following methods are commonly adopted in clinical practice to deal with this situation: ① external application of ice bags; ② pressure bandage of the puncture limb; ③ patients raising the operated limb by themselves, etc., but there are also the following problems: first, external application of ice bags cannot accurately control the temperature and the ice bags do not fit tightly to the skin surface and cannot be fixed. In addition, conventional ice bags are hard in texture, and patients often feel uncomfortable when applying ice, which often leads to unsatisfactory ice effects; secondly, the pressure of the pressure bandage of the puncture limb cannot be accurately controlled. If it is too loose, it will not have a pressurization effect, and if it is too tight, it will often cause pain and discomfort to the patient; in addition, asking the patient to raise the operated limb by themselves often makes the patient tired due to raising it for too long, resulting in poor compliance. If the forearm swelling cannot be properly treated, obvious ecchymosis and blisters can often be seen on the skin of the affected limb. In more serious cases, compartment syndrome may even occur, which is often manifested by the following five symptoms: ① pain or pain turning into no pain; ② pallor; ③ pulselessness; ④ paralysis; ⑤ paresthesia. Surgical incision of the fascia to decompress the muscles and nerves is required to prevent ischemic necrosis of the muscles and nerves. If the patient has obvious symptoms of the above five symptoms, it often indicates that the best time for treatment has been lost, which may lead to serious consequences such as limb disability or even amputation. The above adverse consequences after radial artery puncture intervention not only increase the patient's pain, infection and disability risks, but also increase their medical expenses and prolong hospitalization time.

[0004] In addition, the EASY classification and treatment opinions for hematoma after transradial PCI published in the journal Circulation pointed out that applying pressure, ice and raising the operated limb 45° to 60° on the patient's operated limb can effectively relieve forearm swelling complicated by coronary intervention. And studies have shown that the pressure of the pressurized pressure of patients with forearm hematoma after intervention is 10-20mmHg (1mmHg = 0.133kPa) higher than the patient's systolic blood pressure is more effective in stopping bleeding and reducing swelling. However, the current clinical methods of bandage pressure dressing and ice bag external application cannot effectively relieve forearm swelling, and the two methods cannot be performed at the same time. If ice is applied to the skin, the bandage pressure dressing cannot be performed, and the bandage pressure dressing and ice bag external application at the same time cannot fit the skin surface and cannot reach the temperature required for ice, resulting in poor swelling relief effect, and the bandage cannot observe the color of the patient's swollen skin. In addition, patients who are asked to raise their operated limbs have poor compliance.

[0005] Therefore, there is an urgent need for more appropriate methods to alleviate the problem of forearm swelling in patients. Summary of the invention

[0006] The invention purpose of this application is to provide a pressure cryotherapy device for relieving forearm swelling in patients. The pressure cryotherapy device is a pressure cryotherapy device for treating forearm swelling complicated by transradial artery intervention. It is a double-layer transparent airbag cuff that continuously applies pressure to the swollen part of the patient's forearm and lifts the patient's operated limb through a lifting support to promote blood return to the affected limb. In addition, the airbag cuff is equipped with a polymer hydrogel cryotherapy patch that fits tightly to the skin surface, which can play a role in cooling, relieving pain, and stopping bleeding.

[0007] The present application provides a pressure cold therapy device for treating forearm swelling complicated by transradial artery intervention, comprising:

[0008] Elevator support, used to elevate the patient's forearm;

[0009] an airbag cuff, disposed on the lifting support and used to fix the patient's forearm; and

[0010] A connecting piece is used to detachably connect the lifting support and the airbag cuff.

[0011] Furthermore, the lifting support includes an upper arm placement portion and a forearm cuff placement portion, the upper arm placement portion is used to lift the patient's upper arm, and the forearm cuff placement portion is used to fix the airbag cuff.

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

[0013] Furthermore, the airbag cuff is an inflatable pressurized structure, the airbag cuff is connected with a connecting tube, and an end of the connecting tube away from the airbag cuff is connected with an air pump.

[0014] Furthermore, the airbag cuff is also provided with an inflation pressure setting knob, and the inflation pressure setting knob contains a control chip, a pressure sensor, and a proportional valve for achieving continuous pressure control.

[0015] Furthermore, the airbag cuff is configured as a transparent airbag.

[0016] Furthermore, the airbag cuff is provided with a built-in pocket, and the built-in pocket is provided with a cold therapy patch.

[0017] Furthermore, the connecting member includes a first connecting member arranged on the lifting support and a second connecting member arranged on the airbag cuff, and the first connecting member and the second connecting member are detachably matched.

[0018] This device can inject pressure into the airbag cuff and the lifting support through the air pump. First, inject appropriate gas into the lifting support to a suitable height. After inflation, remove the air pump and the air nozzle cap pops out. The original injected gas does not escape due to the airtight check valve design. Connect the air pump connecting tube to the airbag cuff, and rotate the pressure control button according to the patient's preoperative blood pressure by injecting gas. The pressure control button contains a control chip, a pressure sensor, and a proportional valve that interact to control the pressurization pressure to maintain 10-20 mmHg higher than the patient's systolic pressure. After the lifting support is filled with gas, the patient can place the cuff in the lifting support and fix it with a buckle to achieve the elevation of the limb. If you need to get out of bed and move around, unfasten the buckle to separate the lifting support from the airbag cuff. In addition, the cuff is equipped with a polymer hydrogel cold therapy patch to cool down, relieve pain, and stop bleeding. The cold compress effect lasts for a long time and can be removed freely when not in use or replaced.

[0019] In summary, the pressure cold therapy device for treating forearm swelling following radial artery interventional surgery of the present application can perform pressure bandaging and elevate the operated limb while closely adhering to the skin for cold therapy. The pressurization pressure can be controlled and adjusted individually according to the patient's condition, and the transparent airbag design can be used to check the skin color of the patient's swollen area. The cold therapy uses a polymer hydrogel cold therapy patch, which can better fit the skin surface and has a softer texture. The cold therapy time is long and the effect is significant. There is no need to frequently replace the cold therapy patch, which reduces the nursing workload, improves patient compliance, and promotes patient recovery. BRIEF DESCRIPTION OF THE DRAWINGS
