Problems solved by technology

Cardiopulmonary resuscitation for non-traumatic cardiac arrest has been studied for many years, and the American and European guidelines for cardiopulmonary resuscitation have been updated several times. However, for hemorrhagic cardiac arrest, there is a lack of more direct and effective infusion for rapid restoration of coronary artery and cerebral perfusion pressure. , blood transfusion resuscitation measures

Embodiment 1

[0032] Example 1: Intraaortic double-level balloon occlusion pressurized infusion system

[0033] Intraaortic double-level balloon blocking pressurized infusion system of the present invention, such as figure 1 As shown, it includes: main catheter 3, its top end is the main catheter infusion outlet 1, and its tail end is the first tail end injection port 9 for perfusing liquid or blood; aortic arch balloon 2, connected to the main catheter 3 The part below the top; the aortic arch balloon injection catheter 12 is attached to the main catheter 3; the top of the aortic arch balloon injection catheter 12 communicates with the aortic arch balloon 2; the bottom end of the aortic arch balloon injection catheter 12 is used to inject Inject gas or sterile water into the aortic arch balloon into the second tail injection port 5, and be introduced to the outside; aortic distal balloon 4, connected to the middle part of the main catheter 3; aortic distal balloon injection The catheter 1...

Embodiment 2

[0039] Embodiment 2: application test experiment

[0040] Experimental materials: 26 New Zealand rabbits aged 3 to 4 months, male or female, weighing between 1.7 and 2.8 kg.

[0041] All animals were purchased from the Animal Center of Nanfang Hospital. Raise them in a standardized environment with 12 h alternating light and dark, constant temperature, and provide sufficient food and water. The health status of the experimental animals complied with the national general experimental animal health standards.

[0042] The experimental operation method is as follows:

[0043] Animal preparation:

[0044] Inject 3% pentobarbital sodium through the ear vein (1ml·kg -1 )anaesthetization. The No. 3 trachea was intubated through the orotrachea, and the rabbit breathed freely after the intubation was successful. Electrocardiogram electrodes were respectively connected to the forelimbs on both sides and the left lower abdomen to record the electrocardiogram. Fix the animal's limb...

Abstract

The invention discloses an aortic intracavitary double-horizontal-sacculus blockage pressurized infusion system. The system comprises a main catheter, an aortic arch sacculus, an aortic arch sacculus injecting catheter, an aortic distal sacculus and an aortic distal sacculus injecting catheter, wherein a main catheter infusion outlet is formed in the top end of the main catheter, and the tail end, introduced to the outside of the body, of the main catheter is a first tail end injecting hole; the aortic arch sacculus is connected to the part below the top end of the main catheter; the aortic arch sacculus injecting catheter attaches to the main catheter; the top end of the aortic arch sacculus injecting catheter communicates with the aortic arch sacculus; the bottom end, introduced to the outside of the body, of the aortic arch sacculus injecting catheter is a second tail end injecting hole; the aortic distal sacculus is connected to the middle section part of the main catheter; the aortic distal sacculus injecting catheter attaches to the main catheter; the top end of the aortic distal sacculus injecting catheter communicates with the aortic distal sacculus; and the bottom end, introduced to the outside of the body, of the aortic distal sacculus injecting catheter is a third tail end injecting hole. For the aortic intracavitary double-horizontal-sacculus blockage pressurized infusion system, the rescuing resuscitating success rate for patients suffering from hemorrhagic sudden cardiac arrest can be improved by improving the effective continuous blood perfusion for the important organs including the heart, the brain, the kidney and the like.

Description

technical field [0001] The invention belongs to the field of emergency cardiopulmonary resuscitation for traumatic hemorrhagic cardiac arrest, and relates to a pressurized infusion system in the aortic cavity, in particular to a double-level balloon blocking pressurized infusion system in the aortic cavity. Background technique [0002] According to statistics, trauma is the leading cause of death among people aged 0-44. Among cardiac arrests caused by trauma, blood loss is the most common cause of cardiac arrest directly caused by trauma, accounting for 40%. When a traumatic hemorrhagic cardiac arrest (CA) occurs, time is pressing and it is the same as a non-traumatic cardiac arrest. The blood volume in large blood vessels such as the cavity and aorta is based on a sharp drop, resulting in cardiac arrest. At this time, while routine cardiopulmonary resuscitation (CPR) is performed, the rapid and large amount of fluid and blood transfusion in the circulatory system becomes ...
