Description

A cardiac pacemaker fixation device

technical field

The invention belongs to the technical field of medical devices, in particular to a cardiac pacemaker fixing device.

Background technique

Permanent cardiac pacemaker implantation is one of the most common interventional procedures in cardiology. It is clinically used in patients with cardiac pacing and conduction dysfunction, dilated cardiomyopathy, heart failure, malignant arrhythmia, etc.; postoperative wound compression for hemostasis and limb immobilization is essential. After operation, 1.0kg sandbag was used to compress the wound for 6 hours, and the pressure was released every 2 hours for 5 minutes. If there was potential bleeding, the compression time was increased to 24 hours. Generally, patients use abdominal girdle to stop bleeding after 6 hours of compression. The abdominal girdle usually takes 3-4 days to stop bleeding. If patients need to use anticoagulants, they may need to be used for a long time, and some need to be used for more than 1 month. The patient's upper limb on the operating side should avoid abduction, external rotation, and lifting to prevent the pressure object from shifting and causing wound bleeding; at the same time, the patient's upper limb on the operating side should also avoid overstretching and pulling, which may cause poor contact of the pacemaker lead and lead to injury. The risk of cardiac pacing dysfunction and even the possibility of pocket hematoma.

At present, in clinical practice, for patients with cardiac pacemakers, the upper body of the patient is bandaged to prevent bleeding at the surgical site. However, this operation method is likely to lead to poor patient compliance and tolerance, because the patient's weight, fat and thinness Different, but the abdominal girdle is the same size and cannot be adjusted at will according to the patient's height and weight. Especially for female patients, the chest muscles are severely compressed, which will cause poor breathing; the compressed salt bag is easy to follow the patient's activities. Displacement, resulting in local bleeding; the existing abdominal girdle has no timing function, and most patients are elderly, many patients cannot remember the compression time, or the compression time depends on the feeling, and the medical staff spends a lot of time to record the compression time and experience, the compression time is not allowed to cause insufficient compression bleeding or too long compression time, local tissue pressure injury and other complications; the existing abdominal girdle cannot effectively restrain the lift and abduction of the left upper limb, and the upper limb on the affected side is too active , causing the pacemaker electrodes to fall off and affect the pacemaker's pacing function, resulting in serious consequences; when the patient uses the traditional abdominal belt, in order to achieve the goal of compression and hemostasis, the restraint is often tight, and improper restraint affects normal daily life. , and it will also cause discomfort and pressure injury due to the compression of a large area of the patient's chest, and it is inconvenient to put on and take off.
