Description

Technical Field

[0001] The utility model relates to the technical field of temporary pacemakers, in particular to the technical field of temporary pacemaker fixing devices. Background Art

[0002] Temporary cardiac pacing is an emergency and effective measure for treating severe arrhythmias. It is an emergency means of cardiopulmonary resuscitation. It can also provide safety protection for patients to safely, smoothly and smoothly pass through the surgical anesthesia period. It is more commonly used in the perioperative period. A temporary pacemaker is a non-permanently implanted temporary cardiac pacing device, usually including a pacemaker body located outside the body and a pacing electrode placed in the body through surgery (the implantation time of the pacing electrode is generally 1 to 2 weeks, not more than 4 weeks).

[0003] During use, one end of the pacing electrode is usually electrically connected to the pacemaker body through a connector, while the other end is extended to the patient's heart along the skin incision. Currently, in order to prevent the pacing electrode from shifting, doctors usually fix the pacing electrode on the skin surface by applying a patch and sutures during temporary cardiac pacing, such as "[1] Wang Yuesong et al. "Application of bedside temporary pacemakers in surgical operations." Jiangsu Medicine 029.010(2003):798-799." and "[1] Fang Yuqiang et al. "Discussion on the indications of temporary pacemakers in elderly patients undergoing non-cardiac surgery." Chongqing Medicine 39.002(2010):161-163."

[0004] Currently, there is no unified fixation method for temporary pacemakers. Most of them are fixed with a patch and sutures, but there is a risk of curling of the patch and accidental removal. Temporary pacemakers are generally placed directly on the bed on one side of the patient (taking the pacing electrode entering the body from the groin as an example) or the cable is simply attached to the patient's skin surface with tape or other fixing methods. However, the patient's unconscious behavior when falling asleep at night can easily lead to the risk of accidental removal of the temporary pacemaker wire, especially for uncooperative or elderly patients, the risk of extubation is higher. Temporary pacemakers in the groin can easily cause contamination of the area when the patient defecates, thereby increasing the risk of infection.

[0005] Currently, to prevent extubation, patients are often restrained in both upper limbs and the lower limb on the side where the pacemaker is implanted. For awake patients, these restraints are detrimental to their mental health and can cause physical discomfort. Consequently, many patients and their families resist this restraint, which complicates nursing care. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems in the prior art and to propose a temporary pacemaker fixation device, which can effectively reduce the curling of local puncture applications, reduce the risk of extubation, and reduce infection.

[0007] To achieve the above-mentioned purpose, the present invention proposes a temporary pacemaker fixing device, including a base and a buckle. The bottom surface of the base is provided with a base self-adhesive layer with release paper, and the top surface is provided with a base recess and a base groove for embedding a connector and a pipeline respectively. One end of the base groove is connected to the base recess and the other end is connected to the edge of the base. The buckle is arranged on the top surface of the base along the base groove and can restrain the pipeline together with the base.

[0008] Preferably, it further comprises a top film which can directly cover the base and the buckle from the top when in use, the bottom surface of the top film is provided with a self-adhesive layer of the film with release paper, and the area of ​​the top film is larger than that of the base.

[0009] Preferably, the top film is a transparent film.

[0010] Preferably, the buckle is in an inverted U-shape, one end of which is fixed to the base, and an opening for pipelines to enter and exit is formed between the other end and the base.

[0011] Preferably, the buckle includes a buckle base, a movable column and a torsion spring, one end of the buckle base is fixed to the base and the other end is hinged to one end of the movable column after bending downward, and the torsion spring is installed at the connection between the buckle base and the movable column and has an elastic tendency to push the free end of the movable column close to the fixed end of the buckle base.

[0012] Preferably, the buckle further includes a locking mechanism capable of limiting the free end of the movable column from being away from the fixed end of the buckle base.

[0013] Preferably, an upper protrusion is provided on the buckle base, and the locking mechanism includes a slide rail, a slider, a connecting rod and a lock head. The slide rail is arranged on the upper protrusion, and the slider can slide up and down along the slide rail and is indirectly connected to the lock head through the connecting rod. The lock head is located on the side of the fixed end of the movable column facing away from the buckle base.

[0014] Beneficial effects of the utility model:

[0015] 1) By directly adhering the base with the buckle to the skin surface, the base body notch and groove on the top surface of the base body can be used to respectively fit the connector and the pipeline to achieve a first level of auxiliary reinforcement. On the other hand, the base and the buckle can be used to restrain the pipeline to achieve a second level of auxiliary reinforcement, thereby effectively reducing the chance of accidental dislocation of the temporary pacemaker due to improper fixation at the puncture site, thereby causing electrode dislocation.

[0016] 2) By adding a transparent top film to directly cover the base, buckle, fixed connector, and some pipelines from above, it not only does not affect medical staff's normal observation of the connection parts, but also provides a third layer of auxiliary reinforcement for the connection parts, effectively reducing the health and safety risks caused by accidental extubation through a triple guarantee approach;

[0017] 3) By combining the buckle base, movable column and torsion spring to form a buckle, the elastic force of the torsion spring can automatically retract the movable column to clamp the pipeline together with the buckle base, and the pipeline can be quickly released when the movable column is manually pulled out, thereby improving convenience and flexibility.

[0018] 4) By adding a locking mechanism consisting of a slide rail, a slider, a connecting rod and a lock head on the buckle, the lock head can support the side of the movable column facing away from the fixed end of the buckle base after moving downward, thereby effectively preventing the movable column from releasing the pipeline prematurely.

[0019] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
