Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a temporary pacing device. Background Art

[0002] Temporary pacing wires were first used in clinical practice in 1960. They were intended for temporary pacing when patients experienced severe atrioventricular block, sick sinus syndrome, sinus bradycardia, low cardiac output and other adverse events after surgery. The incidence of severe arrhythmia events varies with different cardiac surgeries. Among patients undergoing coronary artery bypass grafting, more than 100 research analyses have shown that the overall incidence of atrioventricular block requiring temporary pacing is approximately 2.4%. However, pacing wires are still routinely used in various types of surgeries. Severe perioperative arrhythmia events and complications such as low cardiac output mainly occur within 72 hours after surgery. The use rate of temporary pacing wires after 72 hours is low. This overlaps to a large extent with the placement time of pericardial drainage tubes.

[0003] In clinical use, one pole (cathode) of the pacing lead is sutured under the xiphoid process during surgery, and the other end is exposed to the body surface. Since there are no special structures around it, it is relatively safe and simple to remove. The other pole (anode) of the temporary pacing lead passes through 1-2mm into the myocardium, and the lead needs to be bent to be fixed on the surface of the myocardium, which also makes it relatively difficult to remove the temporary lead after surgery. Therefore, in clinical practice, many patients only cut off the external part of the pacing lead, and some parts remain in the body. Because it is difficult to cut off the skin and pass through the chest wall to form sinus tracts, it is easy to cause local inflammatory reactions and spread of infection. At the same time, some patients have obvious foreign body sensation in the body, resulting in a decrease in quality of life, so they have to surgically incise the skin for surgical removal, or even split the sternum to completely remove it. In the process of removing the lead in the ward clinically, myocardial damage, bleeding, and even pericardial tamponade are also likely to occur.

[0004] In 2021, there will be nearly 300,000 cardiac surgeries in China, and the number is increasing year by year. The number of patients whose pacing leads cannot be effectively removed is also increasing year by year. Therefore, it is very important to design a temporary pacing device that can be easily removed without causing additional damage. Utility Model Content

[0005] The purpose of the utility model is to provide a temporary pacing device to solve the deficiencies in the prior art.

[0006] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:

[0007] A temporary pacing device comprises a pericardial drainage tube, wherein a metal ring is sleeved on the outer wall of the head end of the pericardial drainage tube, a temporary pacing wire is fixed on the inner wall of the pericardial drainage tube, and the temporary pacing wire is connected to the metal ring.

[0008] Preferably, the pericardial drainage tube is a transparent tube made of silicone with a length of 60-80 cm, an inner diameter of 3-4 mm, and an outer diameter of 6-8 mm.

[0009] Preferably, a plurality of drainage holes are opened within 10 cm of the head end of the pericardial drainage tube, and adjacent drainage holes are arranged alternately up and down.

[0010] Preferably, the metal ring is made of platinum, has a length of 2-3 cm, and a thickness of 1 mm, and is fixed between the two drainage holes at the front end.

[0011] Preferably, the drainage holes have a hole spacing of 2-3 cm and a hole diameter of 3-4 mm.

[0012] Preferably, the temporary pacing wire is made of platinum and has a diameter of 1 mm.

[0013] Preferably, scale marks are provided on the outer wall of the pericardial drainage tube.

[0014] Preferably, the temporary pacing lead passes through the pericardial drainage tube at 30-40 cm, and the passing part is wrapped with insulating rubber and connected to an external temporary pacemaker. The end of the pericardial drainage tube is connected to a drainage bag.

[0015] The temporary pacing device provided by the utility model has the following advantages compared with the prior art:

[0016] The utility model combines a temporary pacing wire with a pericardial drainage tube. The placement position of the pericardial drainage tube coincides with the placement position of the temporary pacing wire. The placement time of the pericardial drainage tube overlaps with the possible use time of the temporary pacing wire. Although the use time may not match, the effect of appropriately extending the placement time of the pericardial drainage tube is relatively small, and the temporary pacing wire placement time is more relaxed. Therefore, combining the two can very well solve the adverse effects caused by the residual temporary pacing wire in the body and improve the patient's quality of life.

Therefore, combining the two can very well solve the adverse effects caused by the residual temporary pacing wire 3 in the body and improve the patient's quality of life. The anode of the temporary pacing wire 3 is combined with the pericardial drainage tube 1 and attached to the surface of the myocardium. The other pole is sutured under the xiphoid process with a conventional temporary pacing wire, and the end of the wire is exposed to the outside of the body for use when needed.
