Description

Technical Field

[0001] The present invention relates to the field of cardiopulmonary resuscitation equipment, and in particular to an intrapericardial air bag pacing implant kit. Background Art

[0002] External chest compression in cardiopulmonary resuscitation is the most basic and important emergency treatment technique, and is widely and standardizedly used in both out-of-hospital and in-hospital emergency treatment. The effectiveness of manual chest compression depends on the endurance and skills of the rescuer. Manual chest compression can only provide about 30% of the normal cardiac output during cardiopulmonary resuscitation. Manual cardiopulmonary resuscitation is also limited by the prolonged manual stop time. Its quality is particularly poor when performed during patient transfer.

[0003] On this basis, in order to reduce the problem of resistance encountered in external compression and the problem of relying on the endurance and skills of personnel, a method of intrathoracic cardiac compression has emerged, which uses surgical means to open the chest cavity and directly contact the heart. Due to the difficulty and risk of the operation and poor prognosis, this technology has been almost eliminated in clinical practice except for its use in open-chest surgery. Therefore, some devices and technologies have emerged that use minimally invasive puncture methods to implant balloon catheters into the chest cavity and perform compressions inside and outside the chest.

[0004] Although the aforementioned device does not require thoracotomy, due to the anatomical structure of the heart and chest, the numerous organs and membranes, and the complex structure of the surrounding blood vessels, although the balloon can theoretically be implanted in the chest and compress the heart when inflated, an anatomical analysis has found that it is actually difficult to implant the balloon structure into the chest and ensure that it operates stably and effectively, making the balloon and other structures unsuitable for implantation outside the heart. Specifically, the complexity of the vascular structure of the organs in the chest makes stable implantation and fixation more difficult, which can easily affect the timing of rescue. In addition, the blood vessels around the heart will also be affected by the balloon, which will squeeze the heart and also squeeze the surrounding important blood vessels (such as the aorta, coronary artery or other large blood vessels), which will in turn affect the normal function of the heart. Therefore, there is a need to provide an implantable pacing device that is more suitable for the anatomical structure of the heart without using a thoracotomy to directly compress the heart. Summary of the Invention

[0009] Optionally, the main body includes a retention segment, which is retained inside the pericardial cavity. A accommodating cavity is also provided inside the retention segment. The accommodating cavity is located between the air inlet channel and the guide channel. The accommodating cavity and the guide channel are connected. The airbag is located in the accommodating cavity. A slot is opened on the lower side tube wall of the retention segment along the length direction of the retention segment, and the slot connects the guide channel with the outside world.

[0010] Optionally, the airbag includes an inner membrane layer and an outer membrane layer, the outer membrane layer is made of non-elastic PC material, and the inner membrane layer is made of latex. When the air pressure in the airbag increases, the inner membrane layer expands.

Intracavity expansion and swelling. Due to the anatomical structure of the pericardial cavity, the airbag will extend downward in the limited pericardial cavity after opening and tend to wrap the left and right ventricles, thereby making the position of the airbag more stable and producing a more effective hemodynamic effect, achieving a heart compression effect that is more suitable for the anatomical structure of the heart.

[0020] The present invention is described below by means of several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numeral in each drawing.

[0021] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 This is a cross-sectional view of the pericardial balloon pacing implant kit provided by an embodiment of the present invention in a non-pressed state. Figure 2 This is a cross-sectional view of the pericardial balloon pacing implant kit provided by an embodiment of the present invention in a compression state. Figure 3 This is a side view of a partial structure of the pericardial balloon pacing implant kit provided by an embodiment of the present invention when in use. Figure 4This is a cross-sectional view of the pericardial airbag pacing implant kit provided by an embodiment of the present invention when compressing the heart, as shown in FIG. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an embodiment of the present invention provides an intrapericardial balloon pacing implant kit, comprising: a guide assembly 1, an expansion catheter assembly 2, and an inflation and deflation assembly, wherein the guide assembly 1 comprises a first guide wire 11, a portion of the first guide wire 11 is located inside the pericardial cavity of the target heart, the expansion catheter assembly 2 comprises: a main body 21 and an air bag 22, the main body 21 has a guide channel 211 and an air inlet channel 212 parallel to each other, the first guide wire 11 is slidably connected to the guide channel 211, and the first guide wire 11 is connected to the guide channel 211. 11 guides the main body 21 to move into the human body, the airbag 22 is provided on the main body 21, and the airbag 22 is connected to the air inlet channel 212. The main body 21 is provided with a slot 214 along its axial direction. Under the guidance of the first guide wire 11, the airbag 22 is embedded in the pericardial cavity of the target heart, and air is introduced through the air inlet channel 212 to make the airbag 22 extend along the slot 214 and wrap around the outside of the ventricle. The inflation and deflation assembly is connected to the airbag 22 to make the airbag 22 expand / contract in the pericardial cavity to squeeze the ventricle.

[0022] Specifically, refer to Figures 1 to 3 When in use, one end of the first guide wire 11 is sent into the pericardial cavity by using the existing puncture technology, so that part of the first guide wire 11 is located in the pericardial cavity. Then, the dilatation catheter assembly 2 is introduced from the distal end of the first guide wire 11, so that the first guide wire 11 penetrates the guide channel 211 in the main body 21, thereby guiding the main body 21 toward the human body so that the part of the main body 21 facing the human body enters the pericardial cavity, and the airbag 22 also enters the pericardial cavity along with the main body 21. At this time, the airbag 22 is still folded in the slot 214 of the main body and has not been unfolded. Subsequently, the airbag 22 is extended from the slot 214 by inflating the air inlet channel 211, and the airbag 22 is inflated by the inflation and deflation assembly, so that the airbag 22 expands in the pericardial cavity. Due to the anatomical structure of the pericardial cavity, the airbag 22 will expand in the pericardial cavity after it is opened. The airbag 22 extends downward within the limited pericardial cavity and has a tendency to wrap around the left and right ventricles, thereby making the position of the airbag 22 more stable and producing a more effective hemodynamic effect, achieving a heart compression effect that is more suitable for the cardiac anatomical structure. The airbag 22 squeezes the heart (squeezes the ventricles) in the pericardial cavity, resulting in a certain increase in the ventricular contraction force and amplitude; after inflation is completed, the gas in the airbag 22 is sucked out under negative pressure through the inflation and deflation components, so that the ventricles are fully dilated, thereby forming a cycle of pacing and compression. According to different situations, medical personnel can use various methods and appropriate basis to determine the timing and time of inflation / deflation. In the above process, a guide component is used to deliver part of the expansion catheter component into the pericardial cavity, so that the airbag compresses the heart for resuscitation / pacing in the pericardial cavity.

[0023] In the above process, the guide component 1 is used to deliver part of the dilatation catheter component 2 into the pericardial cavity, so that the airbag 22 performs compression, resuscitation / heart pumping in the pericardial cavity. Due to the anatomical structure of the pericardial cavity, after the airbag 22 is opened, it will extend downward within the limited pericardial cavity and tend to wrap the left and right ventricles, thereby making the position of the airbag 22 more stable and producing a more effective hemodynamic effect, achieving a heart compression effect that is more suitable for the anatomical structure of the heart.

[0024] refer to Figure 5 The guide assembly 1 also includes a first catheter 12, and the first catheter 12 enters the pericardial cavity at one end toward the human body. The first guide wire 11 is placed inside the first catheter 12. The first catheter 12 guides the part of the first guide wire 11 toward the human body into the pericardial cavity. When part of the first guide wire 11 enters the pericardial cavity, the first catheter 12 withdraws from the body to allow the first guide wire 11 to detach from the first catheter 12. The first guide wire 11 is made of a memory alloy. The first guide wire 11 tends to deform when heated. The part of the first guide wire 11 extending out of the first catheter 12 is deformed and bent, thereby embracing the outer side of the pericardial visceral layer in the pericardial cavity. The airbag 22 expands after inflation and embraces the outer side of the pericardial visceral layer, and covers the outer side of the ventricular part when the airbag 22 expands.

[0025] During use, first puncture the first catheter 12 into the pericardial cavity, and then send the first guide wire 11 into the pericardial cavity along the inside of the first catheter 12. The tip of the first guide wire 11 should avoid contacting the myocardium to avoid arrhythmia. At this time, the free coiling state of the first guide wire 11 in the pericardial cavity can be observed under fluoroscopy, and then the first catheter 12 is withdrawn, and the first guide wire 11 is retained as a track. The distal end of the first guide wire 11 needs to retain a sufficient length (usually ≥20 cm) to ensure the stability of subsequent operations. Then, after the surgical area is disinfected, the dilation catheter assembly 2 is introduced from the distal end of the first guide wire 11, and the dilation catheter assembly 2 is inserted into the distal end of the first guide wire 11. A guide channel 211 is provided in the main body 21 of the tube assembly 2. It is necessary to ensure that the first guide wire 11 passes through the entire process without being bent. When pushing, a rotating forward technique is used to reduce tissue resistance, so that the first guide wire 11 penetrates the guide channel 211 in the main body 21, thereby guiding the main body 21 toward the human body so that the part of the main body 21 facing the human body enters the pericardial cavity. Under fluoroscopic monitoring, the main body 21 is pushed along the guide wire to the target position in the pericardial cavity. When pushing, attention should be paid to the tension of the first guide wire 11 to avoid penetrating the visceral pericardium. The airbag 22 also enters the pericardial cavity along with the main body 21.

[0026] The atrioventricular groove (AV Groove) is an annular depression on the surface of the heart that separates the ventricles. It contains important coronary blood vessels (such as the right coronary artery and the coronary sinus). The visceral pericardium (Visceral Pericardium) is in close contact with the myocardium here, forming a natural guidewire anchoring area. Therefore, the deformed portion of the first guidewire 11 surrounds the outer side of the visceral pericardium at the AV Groove, thereby guiding the dilatation catheter assembly 2 to surround the outer side of the visceral pericardium at the AV Groove.

[0027] Optionally, the main body 21 includes a retention segment, which is retained inside the pericardial cavity. A accommodating cavity 213 is also provided inside the retention segment. The accommodating cavity 213 is located between the air inlet channel 212 and the guide channel 211. The accommodating cavity 213 and the guide channel 211 are connected. The airbag 22 is located in the accommodating cavity 213. A slot 214 is opened on the lower side tube wall of the retention segment along the length direction of the retention segment. The slot 214 connects the guide channel 211 with the outside world.

[0028] The retention segment is naturally wrapped around the outside of the ventricle as the head of the first guide wire 11 is curved. After the retention segment reaches the pericardial cavity, air is blown out of the airbag 22 in the accommodating cavity 213 through the air inlet channel 212. Part of the airbag 22 extends from the slot 214. As the inflation and deflation assembly is inflated, the airbag 22 expands and then abuts the outer wall of the ventricle.

[0029] Optionally, the airbag 22 includes an endocardial layer and an adventitia layer, the adventitia layer is made of non-elastic PC material, and the endocardial layer is made of latex. When the air pressure in the airbag 22 increases, the endocardial layer stretches. The main purpose of the endocardial layer contacting the ventricle is that when the airbag 22 is inflated, the pressure is squeezed inward, and the outer airbag wall cannot stretch, which can more effectively squeeze the outer wall of the heart ventricle and increase the heart contraction and pumping effect.

[0030] Optionally, the inflation and deflation components include an inflation component, a deflation component, a processing element and a detection component. The inflation component and the deflation component are respectively connected to the end of the air inlet channel 212 away from the human body, the detection component is signal-connected to the processing component, and the processing component is signal-connected to the inflation component and the deflation component. The detection component is used to detect the electrocardiogram signal of the target heart. The processing component sends an inflation signal to the inflation component or sends a deflation signal to the deflation component according to the different electrocardiogram signals. The inflatable component can adopt a micro air pump (piezoelectric / centrifugal), a high-precision flow valve, and a pressure buffer tank. The flow range is: 0-500 mL / s (adjustable), the maximum output pressure is: 300 mmHg (safety threshold can be set), and a Venturi effect acceleration module can be used to achieve emergency inflation within 50ms. A built-in HEPA filter ensures the sterility of medical gas; the deflation component may include: a vacuum generator (vortex type), a pressure relief solenoid valve, a gas recovery bag, and adopts active negative pressure suction (-50 to -100 mmHg) and an adaptive pressure relief algorithm to prevent excessive negative pressure in the pericardial cavity.

[0031] Optionally, the ECG signal includes a QRS wave ECG signal and a T wave ECG signal. When the processing component receives the QRS wave ECG signal, it sends an inflation signal to the inflatable component; when the processing component receives the T wave ECG signal, it sends a deflation signal to the deflation component.

[0032] Furthermore, the guide assembly 1 also includes: a puncture guide wire, the end of the puncture guide wire facing the human body enters the pericardial cavity through puncture, the first catheter 12 is slidably connected to the outside of the puncture guide wire, and the puncture guide wire is used to guide the end of the first catheter 12 facing the human body to enter the pericardial cavity. When the end of the first catheter 12 enters the pericardial cavity, the puncture guide wire can slide out from the end of the first catheter 12 away from the human body. When the puncture guide wire slides out of the first catheter 12, the first guide wire 11 slides from the end of the first catheter 12 away from the human body into the first catheter 12.

[0033] Optionally, a J-shaped guide wire is used as the puncture guide wire, and the first catheter 12 is a deep vein catheter.

[0034] An embodiment is provided, comprising: S1, performing pericardiocentesis, inserting the end of the puncture guide wire 13 toward the human body into the pericardial cavity; S2: Place the end of the first catheter 12 facing the body over the end of the puncture guidewire 13 facing away from the body. Under the guidance of the puncture guidewire 13, the end of the first catheter 12 facing the body is inserted into the pericardial cavity. Then, the puncture guidewire 13 is slidably removed from the end of the first catheter 12 facing away from the body. S3, slide the first guidewire 11 from the end of the first catheter 12 away from the human body into the interior of the first catheter 12, and advance the first guidewire 11 into the pericardial cavity. Simultaneously, operate the tail of the first guidewire 11 to rotate it clockwise and advance it further, so that the first guidewire 11 slides along the right apex of the heart surface toward the atrioventricular groove, and finally approaches and surrounds the atrioventricular groove. Then, the first catheter 12 is withdrawn from the human body along the first guidewire 11. S4, after the first guidewire 11 is separated from the first catheter 12, the balloon dilatation catheter is slidably connected to the outside of the first guidewire 11. Under the guidance of the first guidewire 11, the balloon dilatation catheter enters the pericardial cavity and surrounds the heart; S5. Use the detection component to detect the electrocardiogram of the target heart. When the QRS wave indicating the beginning of the heart's contraction period is detected, the processing component sends an inflation signal to the inflation component. When the T wave indicating the beginning of the heart's diastole is detected, the processing component sends a deflation signal to the inflation component, thereby more effectively performing intrapericardial pacing and increasing cardiac output.
