Description

Technical Field

[0001] This utility model relates to the field of vascular hemostasis technology, specifically a pressure-adjustable extravascular occlusion balloon with drainage and flushing function. Background Technology

[0002] Currently, there are several methods for hemostasis in patients with massive bleeding: 1. Vascular ligation hemostasis, such as ligating both internal iliac arteries to control pelvic bleeding. 2. Interventional vascular embolization hemostasis: using interventional guidewire and catheter techniques to embolize certain bleeding vessels with coils or embolic particles. 3. Pre-placement of arterial balloons for hemostasis. 4. Packing hemostasis: using gauze to apply pressure to the wound to achieve hemostasis, etc.

[0003] The above methods have the following problems: 1. They can cause ischemia in the area supplied by the ligated and embolized blood vessel, leading to complications such as organ ischemia and necrosis, pain, and dysfunction. 2. Complications include bleeding, damage to the vascular intima, vascular rupture, thrombosis, and pseudoaneurysm. 3. Puncture-related complications such as thrombosis and pseudoaneurysm. 4. Ischemia and necrosis of surrounding organs caused by gauze packing. 5. Patients need to undergo two or more surgeries, increasing surgical and anesthesia time and hindering damage control. 6. The surgery is expensive, unaffordable for some patients. 7. Patients and medical staff need to be exposed to X-rays during the procedure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure-adjustable extravascular occlusion balloon with drainage and flushing function. By using an extravascular balloon to compress and occlude, an extravascular occlusion balloon is pre-placed during the patient's surgery. The balloon is expanded to compress the blood vessel to stop bleeding. After hemostasis, the balloon is released to achieve vascular recanalization without affecting the blood supply to the organs in the affected area.

[0005] The purpose of this utility model is achieved through the following technical solution: a pressure-adjustable extravascular occlusion balloon with drainage and flushing function, comprising a tube wall, the front end of the tube wall being configured as a C-shaped tube, the inner side of the C-shaped tube being provided with several balloons that can be squeezed against each other, a balloon catheter being inserted through the tube wall, one end of the balloon catheter being connected to the balloon, and the other end being inserted through the rear end of the tube wall.

[0006] The balloon includes a first balloon and a second balloon. The first balloon is located at the top of the inner side of the C-shaped tube, and the second balloon is located at the bottom of the inner side of the C-shaped tube. The balloon catheter is connected to the first balloon and the second balloon respectively. The main trunk of the blood vessel to be hemostatically stopped is placed between the first balloon and the second balloon. Then, water or air is injected into the first balloon or the second balloon through the balloon catheter, causing the first balloon and the second balloon to expand and flatten the bleeding point of the blood vessel to stop the bleeding. After the bleeding is stopped, water is drawn from the first balloon or air is drawn out through the balloon catheter, causing the first balloon and the second balloon to shrink, and the blood vessel that has been hemostatically stopped can be withdrawn.

[0007] The pipe wall is also provided with several side holes for drainage.

[0008] Several side holes are evenly distributed along the circumference of the tube wall. During the operation, there may be blood, exudate or saline solution after flushing inside the patient's body cavity. If no additional drainage tube is needed, the device can drain all of these out of the body. In this case, a drainage bag needs to be connected to the rear end of the tube wall. The fluid in the body cavity is drained into the tube wall through the side holes and then into the drainage bag from the rear end of the tube wall.

[0009] The pipe wall is made of circular material.

[0010] The pipe wall is also provided with a flushing conduit to prevent blockage. One end of the flushing conduit is located inside the pipe wall, and the other end extends out from the rear end of the pipe wall.

[0011] The tube wall, balloon catheter, and flushing catheter are all equipped with connecting parts, which can be matched with existing medical drainage bags and connecting tubes for effective connection.

[0012] The front end of the tube wall is made of a hard material, while the middle and rear ends are made of a soft material. A hard material means the material has high hardness and a rigid texture, designed to effectively support the balloon and compress the artery. Conversely, a soft material means the material has low hardness and a flexible texture, allowing it to be bent easily and providing good comfort when placed inside the body cavity.

[0013] The beneficial effects of this utility model are:

[0014] 1. This invention does not require puncture of blood vessels, does not affect the vascular endothelium or damage the blood vessel wall, and will not cause related complications.

[0015] 2. This utility model can perform full or partial blockage as needed to ensure the safety of blood supply to the organs it controls.

[0016] 3. It can be performed during surgery without exposure to X-rays.

[0017] 4. Multiple functions are combined, eliminating the need for additional drainage and irrigation tubes, thus avoiding increased trauma and excessive drainage tubes, which would increase the difficulty of postoperative care.

[0018] 5. It can be removed from the body in one operation after the operation, which is simple and does not require suturing blood vessels or secondary surgery.

[0019] 6. Saves surgical time and achieves precise hemostasis.

[0020] 7. Saves on surgical and consumable costs. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] In one embodiment of this application:

[0029] like Figures 1 to 4As shown, a pressure-adjustable extravascular occlusion balloon with drainage and flushing function includes a tube wall 1. The front end of the tube wall 1 is configured as a C-shaped tube. Several balloons that can be squeezed against each other are arranged inside the C-shaped tube. A balloon catheter 5 is inserted through the tube wall 1. One end of the balloon catheter 5 is connected to the balloon, and the other end extends out from the rear end of the tube wall 1.

[0030] The balloon includes a first balloon 2 and a second balloon 3. The first balloon 2 is located at the top of the inner side of the C-shaped tube, and the second balloon 3 is located at the bottom of the inner side of the C-shaped tube. The balloon catheter 5 is connected to the first balloon 2 and the second balloon 3 respectively.

[0031] Pipe wall 1 is selected as a circular pipe wall.

[0032] The front end of the tube wall 1 is made of a hard material, while the middle and rear ends are made of a soft material, which allows the middle and rear ends of the tube wall 1 to be flexible, increasing comfort and reducing postoperative pain for patients.

[0033] First, insert the blood vessel to be stopped into the notch of the C-tube, such as... Figure 2 As shown, the bleeding point is positioned between the first balloon 2 and the second balloon 3. Water or air is then injected into the first balloon 2 and the second balloon 3 through the balloon catheter 5, causing them to inflate and flatten the bleeding point of the blood vessel to stop the bleeding. After hemostasis is achieved, water is removed or air is extracted from the first balloon 2 and the second balloon 3 through the balloon catheter 5, causing them to shrink and releasing the blocked blood vessel, restoring blood supply. This method is primarily used to quickly control massive bleeding and achieve hemostasis without causing permanent loss of blood supply to the controlled blood vessel, thus avoiding related complications caused by ischemia in the organs supplied by that blood vessel.

[0034] In another embodiment of this application:

[0035] Based on the previous embodiment, this embodiment improves the pipe wall 1, and the pipe wall 1 is also provided with several side holes 4.

[0036] Several side holes 4 are evenly distributed around the circumference of the tube wall 1. During and after the operation, there may be blood, exudate, or saline solution after flushing inside the patient's body cavity. If there is too much fluid, it may accumulate in the body and cause complications such as fluid accumulation infection and organ perforation. In this case, a drainage bag needs to be connected to the rear end of the tube wall 1 to drain the fluid in the body cavity into the tube wall 1 through the side holes 4, and then drain it into the drainage bag from the rear end of the tube wall 1.

[0037] A flushing catheter 6 is also installed through the tube wall 1. One end of the flushing catheter 6 is located in the middle or inside the front end of the tube wall 1, and the other end extends out from the rear end of the tube wall 1. If there is a blockage in the tube wall 1, physiological saline is flushed into the tube wall 1 through the flushing catheter 6 to dislodge the blockage.

[0038] The above description is merely an embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
