Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a local pressure device for the maxillofacial area and a method of using the same. Background Art

[0002] In clinical practice, due to the rich blood circulation, numerous interstitial spaces, and loose tissues of the maxillofacial region, maxillofacial injuries, postoperative maxillofacial tumor resection, and parotid gland tumor resection are often accompanied by local swelling, excessive tissue fluid exudation, hemorrhage, dead space formation, and secondary infection, leading to surgical failure and further aggravation of the condition. During the clinical treatment of maxillofacial injuries, postoperative maxillofacial tumor resection, and parotid gland tumor resection, sufficient and continuous pressure must be applied locally to eliminate dead space and promote healing in order to promote wound healing, prevent parotid fistula, and prevent dead space formation. Cross-bandage pressure bandaging and elastic bandage pressure bandaging are commonly used clinically for clinical treatment.

[0003] In summary, during clinical treatment of maxillofacial injuries and surgery, symptoms such as local swelling, pain, tissue fluid exudation, bleeding, and dead space formation may occur. This requires improvement methods that can reduce local swelling, pain, tissue fluid exudation, bleeding, eliminate dead space, and medical assistive devices that continuously apply local pressure.

[0004] According to the above requirements, the current treatment methods for maxillofacial injuries and postoperative conditions mainly include cross-bandage pressure bandages, elastic bandage pressure bandages, and maxillofacial and neck pressure cold compress headbands. However, the current treatment methods have the following shortcomings:

[0005] (1) The controllability of treatment effect is poor, and treatment standards are inconsistent. Due to the irregularity of the maxillofacial area, the eyes, nose, ears, mouth and other organs must be taken into consideration during treatment. The neck must be paid attention to at the mandibular area to prevent pressure from causing breathing difficulties. The cross bandage pressure used in clinical treatment is technically difficult. Clinical treatment requires experienced physicians, and repeated checks are required after each bandage is applied. In clinical practice, the bandages applied by different physicians are different. Even if the bandages applied by the same physician are different each time, the pressure applied by the bandages is different due to various factors, and it is impossible to reach a unified standard, which affects clinical treatment. In addition, clinical treatment often results in unqualified cross bandages, which increase the patient's pain while failing to achieve the purpose of treatment.

[0006] (2) The treatment process is uncomfortable and further increases the patient's pain. The purpose of cross bandage is to achieve local pressure. Clinically, patients often experience headaches and ear pain. The pressure causes difficulty breathing and difficulty opening the mouth, which makes it difficult to eat. Patients often cannot tolerate it and strongly request to remove the bandage. Or patients secretly loosen or shift the bandage, making the treatment more difficult to control and unable to achieve the desired therapeutic effect.

[0007] (3) Both cross bandages and elastic bandages are prone to slipping and shifting, and patients are unable to change them by themselves, making the operation complicated. Patients' bandages become loose and slip off; bandages become wet due to tissue fluid or blood seepage; bandages become loose due to local swelling subsiding; bandages slip off and become loose while patients are sleeping at night; female patients have long hair that is prone to slipping off; hair wrapped for a long time causes sweating and oiliness in the hair, making it more likely to slip off; hair wrapped for a long time causes itching and odor on the patient's head, and scratching further loosens the bandage; both cross bandages and elastic bandages are not available to patients by themselves and must be changed by a professional doctor, which not only causes inconvenience to the patient, but also delays treatment and affects recovery.

[0008] (4) Local pressure is unstable, and the cold compress is ineffective or even impossible to apply. Because the pressure is different each time, the patient feels it sometimes light and sometimes heavy. When applying pressure with an elastic bandage, the pressure will continue to increase, and even cause local tissue necrosis, which is not uncommon in clinical cases.

[0009] In view of this, the present invention is proposed. Summary of the Invention

The present invention can be removed by the patient or his family members with the cooperation of the device, the dressing can be replaced, etc., the operation is simple, and it is not easy to slip off. The patient can remove the device when eating, and can be put on again with the cooperation of the patient or his family members after eating. It can be adjusted according to the pressure value without worrying about affecting the treatment effect. At the same time, there is no need to worry about the bandage loosening or slipping off; even if tissue fluid or blood seeps and wets the dressing, the dressing can be replaced in time to ensure local dryness and cleanliness, reducing the possibility of infection; at the same time, it avoids wrapping the hair for a long time, which leads to embarrassing situations such as sweating, oiliness, itching, and odor of the head. Patients who have been discharged from the hospital can change the dressing by themselves in time, reducing inconvenience and ensuring the treatment effect.

[0029] (4) Local pressure is stable and can be applied locally with cold compress. The present invention can display the pressure value through its pressure sensor device, making the local pressure stable and adjustable at any time. Even if the local swelling subsides, the pressure can be adjusted by a professional physician during regular follow-up visits or examinations, saving time and reducing the treatment pressure of medical workers while ensuring the treatment effect. If a cold compress is required locally, a liquid of appropriate temperature can be injected into the pressurized part, which will not wet the dressing and keep the local area dry. At the same time, the operation can be repeated, which is simple and easy. BRIEF DESCRIPTION OF THE DRAWINGS
