Infection-preventing delayed sternal closure sternum spreading device

Abstract

The invention relates to an infection-preventing delayed sternal closure sternum spreading device, which comprises three parts. The first part is a transparent semi-permeable film, the second part isa spreading device, and the third part is a negative pressure drainage system. The spreading device part comprises an arch plate part, a sternum part and a connection place, wherein the sternum part and the arch plate part are independent completely and are assembled and connected through the connection plate; the sternum part comprises a negative pressure suction system and a sternum groove; andthe negative pressure suction system comprises hexagonal mesh sponge and two incision drainage tubes. The whole structure of the device is designed compactly and delicately, the operation is simple and the cost is low. Most importantly, the device is provided with the negative pressure drainage system, the chance of incision wound infection for delayed sternal closure is minimized, the used spreaders have multiple models and can be applied to sick children with different ages and different types, and the application is wide.

Description

Technical field [0001] The invention relates to a spreading device, in particular to a delayed closing sternum spreading device for preventing infection, and belongs to the field of medical equipment. Background technique [0002] Congenital heart disease is a common and frequently-occurring disease in infants and young children. The incidence of congenital heart disease in my country is as high as 7-8‰. According to statistics, there are about 150,000-200,000 new patients every year in my country, among which children with complicated congenital heart disease account for 30%-40%. The congenital heart disease diagnosis and treatment center in Jiangsu Province has an operation volume of about 1,200 cases per year, and the operation success rate is over 98%. However, a variety of complicated congenital heart diseases, such as dislocation of large vessels, pulmonary atresia, single ventricle, etc., are completely different from normal children because of their hemodynamics. Under ...

Problems solved by technology

3. Application of artificial blood vessels or homologous tubes with valves, sternum compression tubes, causing unstable blood circulation

The first method does not achieve the desired effect because the sternum is not supported and cannot maintain the open state of the sternum. The chest volume is not fixed.

The latter two methods require on-site processing of equipment, which will prolong the operation time, and the on-site processing equipment is not standardized, making it difficult to fix and easy to slip off

[0006] In conclusion, in patients with delayed chest closure, the sternum is exposed and the skin has not been sutured by primary stage, the postoperative infection rate is higher, which increases the pain of the patient
