Description

Technical Field

[0001] The present application relates to a medical device, and more particularly to a wound compression device after pacemaker implantation. Background Art

[0002] For a permanent cardiac pacemaker surgery, an incision about 6 - 7 cm long needs to be made at a position about 5 cm below the left collarbone of the patient. A pocket is formed by peeling under the skin, and a pulse generator of the cardiac pacemaker is placed in the pocket. The shape of the pulse generator is generally oval, and it is connected to the cardiac pacemaker through a wire. After the incision is sutured, it is usually necessary to compress it with a salt bag. During the compression period, the patient can only lie flat, which is not conducive to the patient's activities and is likely to cause venous thrombosis. CN100394896C proposes a "Compression Hemostasis and Pocket Protection Device after Permanent Cardiac Pacemaker Implantation", which compresses the incision and the pocket by fixing an airbag with a chest strap, so that the patient does not need to stay in bed and is convenient for activities. Although this device is convenient for the patient to move, due to the patient's movement, the pulse generator of the pacemaker is likely to shift in the pocket. It is impossible for the pocket formed by peeling to be exactly the same size as the pulse generator. Usually, it is slightly larger than the pulse generator itself, and the redundant part will grow together again later, so that the pocket tightly wraps the pulse generator. However, in the initial stage of pocket formation, if the patient is in an upright position, the possibility of the pulse generator moving in the pocket is still relatively large. The movement of the pulse generator will cause the position of the electrode at the end of the wire to shift, which is not desirable. In addition, during the movement of the patient's left arm, the position of the pulse generator may be shifted by the pulling of the surrounding muscles or tissues. Summary of the Utility Model

[0003] In view of the above problems, the present application aims to propose a wound compression device after pacemaker implantation, which can help the pulse generator of the cardiac pacemaker to be stably maintained in the pocket and is not likely to shift.

[0004] The wound compression device after pacemaker implantation of the present application includes: a chest strap and an airbag; the chest strap includes a main body, on which a right rib strap, a left rib strap, and a shoulder strap are formed; the airbag is formed in a disc shape and is arranged at the rear side of the main body of the chest strap.

[0005] The rear side of the airbag is connected with a silica gel pad through an adhesive; a circular first recess is formed on the front side of the silica gel pad, and the silica gel pad is buckled on the rear part of the airbag through the first recess; a second recess corresponding to the shape of the pulse generator of the pacemaker is formed on the rear side of the silica gel pad; the silica gel pad is arranged on the body surface of the subject through its second side, covering the wound on the body surface of the subject and the pocket under the skin for accommodating the pulse generator of the pacemaker, and is buckled directly above the pulse generator of the pacemaker through the second recess, so that the front part of the pulse generator of the pacemaker partially enters the second recess to limit the displacement of the pulse generator of the pacemaker relative to the pocket.

[0006] Preferably, an arm clip for the left arm is arranged on the left rib band. The arm clip for the left arm is formed with a notch for accommodating the upper arm of the left arm of the subject. Sealing tapes are arranged at both ends of the notch. The first end of the sealing tape is fixed at the first end of the notch, and the second end of the sealing tape can be detachably fixed at the second end of the notch.

[0007] Preferably, a limiting rod extends upward at a position of the arm clip for the left arm corresponding to the left armpit of the subject. The lower end of the limiting rod is fixed on the upper side of the arm clip for the left arm, and the upper end of the limiting rod is used for abutting against the left armpit of the subject.

[0008] Preferably, the upper end of the limiting rod is formed with an arc-shaped upper surface.

[0009] Preferably, through holes are formed in the main body of the chest band; an air nozzle is formed on the front side of the airbag, and the air nozzle extends through the through hole to the front side of the chest band.

[0010] The pacemaker postoperative wound compression device of the present application limits the movement of the pulse generator relative to the pocket through the second recess at the rear side of the silica gel pad; the pacemaker postoperative wound compression device of the present application defines the movement of the upper arm of the left arm through the arm clip for the left arm, thereby avoiding the displacement of the pulse generator caused by the movement of the left arm.

[0017] The pacemaker postoperative wound compression device of the present application includes: a chest strap and an airbag. This is similar to the prior art CN100394896C. The chest strap includes a main body 10, on which a right rib strap 11, a left rib strap 12, and a shoulder strap 13 are formed. The right rib strap 11 and the left rib strap 12 surround the torso of the subject and are connected together at the back by a hook-and-loop fastener. The shoulder strap 13 can be placed on the left shoulder of the patient and is fixed to the left rib strap or the right rib strap at the back by a hook-and-loop fastener. The airbag 20 is formed in a disc shape and is provided at the rear side of the main body 10 of the chest strap; after the airbag 20 is inflated, it is used to apply pressure to the subject.

[0018] The rear side of the airbag 20 is adhesively connected with a silicone pad 30. The front side of the silicone pad 30 forms a circular first recess 31, and the silicone pad is buckled on the rear part of the airbag 20 through the first recess 31; the rear side of the silicone pad forms a second recess 32 corresponding to the shape of the pulse generator of the pacemaker; the silicone pad 30 is arranged on the body surface of the subject through its second side, covering the wound on the body surface of the subject and the pocket under the skin for accommodating the pulse generator of the pacemaker, and is buckled directly above the pulse generator of the pacemaker through the second recess 32, so that the front part of the pulse generator of the pacemaker partially enters into the second recess 32 to limit the displacement of the pulse generator of the pacemaker relative to the pocket.

[0019] A left arm clip 40 is provided on the left rib strap 12. The left arm clip can be combined on the surface of the left rib strap 12 by a hook-and-loop fastener. The left arm clip 40 forms a notch for accommodating the upper arm of the left arm of the subject, and sealing tapes 42 are provided at both ends of the notch. The first end of the sealing tape 42 is fixed to the first end of the notch, and the second end of the sealing tape 42 can be detachably fixed to the second end of the notch, for example, by a hook-and-loop fastener. The left arm clip 40 is mainly used to limit the movement of the upper arm of the left arm of the patient.

[0020] At a position corresponding to the left armpit of the subject on the left arm clip 40, a limiting rod 41 extends upward. The lower end of the limiting rod 41 is fixed to the upper side of the left arm clip 40, and the upper end of the limiting rod 41 is used to abut against the left armpit of the subject.

[0021] The upper end of the limiting rod 41 forms an arc-shaped upper surface.

[0022] The left arm clip 40 can be formed into various models to facilitate the size of the upper arm of the corresponding different left arms and the same axillary height. In use, according to the actual situation of the experimenter, select suitable left arm clip 40 and be connected and fixed on the left side rib belt 12.

[0023] A through hole 14 is formed on the main body 10 of the chest strap, and an air nozzle 21 is formed on the front side of the air bag 20, and the air nozzle 21 passes through the through hole 14 and extends to the front side of the chest strap. A plug can be installed in the air nozzle 21 to facilitate inflation and deflation and closing the air nozzle.

[0024] When in use, first let the subject lie flat, and according to the actual situation of the subject, first buckle the silicone pad to the corresponding position of the sac and the wound. Then stick the airbag to the silicone pad. Then, press the airbag and the silicone pad, let the subject stand up, and keep the relative position of the silicone pad, the airbag and the subject's upper body unchanged during the process of standing up. Set the chest strap on the front side of the airbag, and the air nozzle of the airbag extends to the front side through the main body of the chest strap. Connect and fix the right rib strap and the left rib strap of the chest strap, and then fix the shoulder strap. Finally, clamp the upper arm of the subject's left arm in the left arm clip, and close the gap of the left arm clip with the sealing tape, thereby fixing the upper arm of the subject's left arm. The limit rod of the left arm clip rests on the left armpit of the subject, limiting the upward sliding of the entire device, and the shoulder strap limits the downward sliding of the entire device. Inflate the airbag to expand the airbag, press the silicone pad tightly against the surface of the subject's body, the wound is pressed by the silicone pad, and the pulse generator is clamped in the second recessed part through the skin. In this way, the pulse generator is not easily displaced relative to the capsular bag, the movement of the left arm is also restricted, and it is not easy to pull the tissue around the pulse generator, which will not cause the displacement of the pulse generator. It should be pointed out here that several layers of gauze can be first placed on the surface of the subject's body, and the silicone pad is pressed on the surface of the subject's body through the gauze.
