Technical Field

The utility model relates to the technical field of medical instruments, in particular to a balloon type aortic blood blocking device.

Background

Clinically, patients with traumatic shock often have rapid blood pressure drop in early stages; if bleeding cannot be controlled in time, fluid is replenished and blood pressure is maintained, the effective circulating blood volume of a patient is further reduced, and a high death rate is caused.

An effective method for patients with such severe shock is currently resuscitation aortic balloon occlusion (REBOA). REBOA can block the aorta at the proximal end of the blood loss part, thereby not only effectively controlling blood loss, but also maintaining the proximal blood pressure, so that the limited circulating blood volume is redistributed, and the important organ blood supply of heart, brain and the like is ensured, thus being an important technology for early antishock treatment. REBOA is often used for emergency treatment of traumatic shock patients, can effectively control blood loss, maintain blood pressure and improve treatment rate, and is an important technology for antishock treatment.

However, the balloons used for vascular occlusion in the prior art have disadvantages; for example, the balloon can displace during the plugging process, and cannot be accurately anchored at a designated position, so that the stability and safety of plugging are reduced.

In view of the foregoing, a new solution is needed to solve the above-mentioned problems.

Referring to fig. 2, according to one embodiment of the present utility model, a balloon aortic blood resistor apparatus 1 is provided. The balloon-type aortic blood-blocking device 1 comprises a balloon 11, wherein the balloon 11 comprises a balloon body 111 and a non-slip protrusion 112, the balloon body 111 has a deployment state, and in the deployment state, the balloon body 111 is configured to block a blood vessel of a target area; the anti-slip boss 112 is provided on the outer surface of the balloon body 111; the stud 112 is configured to abut against the inner wall of the vessel in the target area.

Referring to fig. 1, for the balloon aortic blood-blocking device 1 provided in the embodiment of the utility model, the balloon aortic blood-blocking device 1 is generally released in a body in a region a or a region B shown in fig. 1, so as to perform the functions of rapidly blocking blood vessels, maintaining blood pressure, guaranteeing blood supply of vital organs such as heart, brain and the like, and avoiding shock. Wherein, the area A is the thoracic aortic area, and the area B is the abdominal aortic area. C in fig. 1 indicates the entrance of the balloon aortic blood restriction device 1, which is typically accessed via the femoral artery shown in C in fig. 1, but also via the carotid artery.

With the balloon aortic blood blocking device 1 provided by the embodiment of the utility model, when a vessel blocking operation is performed, the balloon body 111 is made to reach a target area, and the balloon body 111 is made to enter a deployed state, so that the balloon body 111 in the deployed state blocks the vessel in the target area. When the balloon body 111 is used for plugging a blood vessel, the anti-slip protrusions 112 arranged on the outer surface of the balloon body are abutted against the inner wall of the blood vessel; the anti-slip protrusion 112 can play an anti-slip role, prevent the balloon 11 from being displaced in the process of vessel occlusion, and ensure that the balloon 11 is accurately anchored at a designated position, thereby improving the stability and safety of vessel occlusion.

Referring to fig. 2, in one embodiment, the stud 112 is integrally formed with the balloon body 111.

In this specific example, the stud 112 is integrally formed with the balloon body 111, so that the connection between the stud 112 and the balloon body 111 is very tight and firm, and the stud 112 does not come off from the balloon body 111. And the forming mode of the anti-slip protrusion 112 is simple, the anti-slip protrusion 112 is formed at the same time of forming the balloon body 111, and any structure is not required to be additionally arranged as the anti-slip protrusion 112, thereby saving the manufacturing process flow of the balloon 11.

Referring to fig. 2, in one embodiment, the outer surface of the balloon body 111 has a non-slip region, the non-slip protrusions 112 are distributed on the non-slip region, and the non-slip region is located at the middle of the outer surface of the balloon body 111.

Since the balloon body 111 is in the deployed state and is in abutment engagement with the vessel inner wall, it is mainly in contact with the vessel inner wall in the middle region; in this specific example, therefore, the non-slip function of the stud 112 can be effectively exerted by providing the stud 112 with the central portion of the outer surface of the balloon body 111 as a non-slip region. And because the two side areas of the outer surface of the balloon body 111 are not contacted with the inner wall of the blood vessel, the anti-slip protrusions 112 are not required to be arranged at the two side areas, so that the arrangement of the redundant anti-slip protrusions 112 is avoided, and the manufacturing cost of the balloon 11 is increased.

Referring to FIG. 2, in one embodiment, the cleats 112 are uniformly distributed across the cleated area.

In this particular example, cleats 112 are uniformly distributed over the area of the cleats such that cleats 112 provide a more stable and reliable cleating action for balloon body 111.

Referring to FIG. 2, in one embodiment, the cleat 112 is circular or elliptical in cross-section.

In this particular example, the cross-section of the stud 112 is in a regular pattern, such as a circle or oval; the manufacturing process of stud 112 is thus relatively simple and easy to operate. And the round or oval-shaped anti-slip protrusions 112 do not damage the vessel wall while performing an anti-slip function.

Referring to fig. 2, in one embodiment, the balloon aortic blood blocking device further comprises a delivery tube 12 and a receiving tube 13, and the balloon body 111 is disposed on the delivery tube 12; the conveying pipe 12 is at least partially sleeved in the accommodating pipe 13; the receiving tube 13 is movable relative to the balloon body 111 and the delivery tube 12 in the axial direction of the receiving tube 13;

the balloon body 111 has a contracted state in which the balloon body 111 is accommodated in the accommodating tube 13, and the balloon body 111 follows the delivery tube 12 and the accommodating tube 13 to a target area.

In this specific example, the balloon body 111 is initially accommodated in the accommodating tube 13, and the balloon body 111 is in a contracted state by the restraining action of the accommodating tube 13. When the vascular occlusion operation is performed, the balloon body 111 is made to follow the conveying pipe 12 and the receiving pipe 13 to reach a target area in the patient body, which is required to be subjected to vascular occlusion, and then the receiving pipe 13 is made to move towards the proximal end, so that the balloon body 111 is separated from the receiving pipe 13 and is exposed outside the receiving pipe 13; after the balloon body 111 is released from the restraining action of the storage tube 13, the balloon body 111 is inflated, for example, with a liquid to switch the balloon body 111 from the contracted state to the expanded state.

Wherein, the far end refers to the end of the balloon type aortic blood blocking device 1 which is far away from an operator when entering a human body, and the near end refers to the end of the balloon type aortic blood blocking device 1 which is near to the operator when entering the human body.

Referring to fig. 2, in one embodiment, the delivery tube 12 includes a catheter 121 and a guide wire 122, the guide wire 122 is sleeved in the catheter 121, and the catheter 121 and the guide wire 122 are connected by bonding, heat sealing, laser welding, etc.; the balloon body 111 is connected with the side wall of the catheter 121 and a part of the catheter 121 is penetrated inside the balloon body 111.

In practical application, first, the catheter 121 and the guide wire 122 are introduced into the human body from the inlet C shown in fig. 1, and the balloon body 111 connected to the catheter 121 then follows the catheter 121 into the human body, and at this time, the balloon body 111 is in a contracted state accommodated in the accommodating tube 13. When reaching the region a or the region B shown in fig. 1, the storage tube 13 is retracted in the proximal direction, and the balloon body 111 is inflated after the balloon body 111 is detached from the storage tube 13, and the balloon body 111 is switched from the contracted state to the expanded state to occlude the blood vessel.

Optionally, marker points may be provided on the catheter 121 to direct the release of the balloon aortic blood restriction device 1 in either region a or region B shown in fig. 1.

Furthermore, in other embodiments, the guidewire 122 is disposed within the catheter 121, and the guidewire 122 is axially movable relative to the catheter 121, such that during use, the guidewire 122 is first advanced from the inlet C shown in FIG. 1 into the body, and then the catheter 121 is advanced along the guidewire 122 into the body, the balloon body 111 attached to the catheter 121 then follows the catheter 121 into the body, and after reaching the desired location, the device is released to complete occlusion of the vessel.

Referring to fig. 2, in one embodiment, the balloon body 111 is integrally formed with the catheter 121.

In this particular example, the integrally formed arrangement of the balloon body 111 and the catheter 121 may allow for a more secure and stable connection between the balloon body 111 and the catheter 121. Of course, in other embodiments, the connection between the balloon body 111 and the catheter 121 may be formed by bonding, heat sealing, laser welding, or the like.

Referring to fig. 2, in one embodiment, a side wall of the catheter 121 is provided with a liquid injection hole 1210 at a position corresponding to the balloon body 111, and when the balloon body 111 follows the delivery tube 12 and the receiving tube 13 to reach a target area, liquid enters the catheter 121 through an opening at a proximal end of the catheter 121 and enters the balloon body 111 through the liquid injection hole 1210 to fill the balloon body 111.

In this specific example, when the balloon body 111 is inflated, liquid is injected from the opening at the proximal end of the catheter 121, and when the liquid flows to a position on the catheter 121 corresponding to the balloon body 111, the liquid flows out from the liquid injection hole 1210 and into the balloon body 111 to inflate the balloon body 111. Alternatively, the liquid may be, for example, physiological saline.

Referring to fig. 2, in one embodiment, the number of the liquid injection holes 1210 is at least two.

In this specific example, the number of the liquid injection holes 1210 is at least two, so that the speed of filling the balloon body 111 with liquid can be increased, and the time required for filling the balloon body 111 can be saved as much as possible.
