Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for the treatment of hemopneumothorax, specifically to a double-lumen bronchial catheter with an internal balloon on the extended bronchus side. Background Technology

[0002] In clinical practice, the establishment of an artificial airway is extremely important in the rescue and treatment of patients with hemopneumothorax. By establishing an artificial airway, on the one hand, invasive mechanical ventilation can be performed on the healthy lung to improve the patient's ventilation and gas exchange function. On the other hand, the bleeding side or the pneumothorax side lung can be isolated and blocked, while avoiding ventilation of the bleeding side or the pneumothorax side lung, which would aggravate lung damage. In the process of establishing an artificial airway, a double-lumen endotracheal tube is required as a tool.

[0003] However, in practical use, current double-lumen bronchial tubes usually use inflatable balloons for fixation to prevent them from falling off and for sealing. By inflating the balloon, the gap between the tube and the tracheal wall is sealed. However, since the double-lumen bronchial tube only has an inflatable balloon outside the extended bronchus, the sealing effect on the bleeding side or the pneumothorax side of the lung is unstable, and pulmonary hemorrhage or air leakage may still occur. Utility Model Content

[0004] The purpose of this invention is to provide a double-lumen bronchial catheter with an internal balloon on the extended bronchus side to solve the above-mentioned problems. The inflation occlusion assembly includes a first inflatable balloon sleeved and fixed to the outer wall of the end of the first and second air delivery pipes, a second inflatable balloon sleeved and fixed to the outer wall of the middle section of the extended bronchus, and a third inflatable balloon coaxially sleeved and fixed to the inner wall of the end of the extended bronchus. In this way, the first inflatable balloon can seal the gap between the first and second air delivery pipes and the patient's tracheal wall, and the second and third inflatable balloons can provide double occlusion of the bleeding side or the pneumothorax side of the lung, improving the stability of the occlusion of the bleeding side or the pneumothorax side of the lung, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a double-lumen bronchial catheter with an internal balloon on the side of the extended branch, including a first air delivery tube, a second air delivery tube and an extended branch tube. The first air delivery tube and the second air delivery tube are connected together and fixedly connected, and the bottom end of the second air delivery tube is fixedly connected to the extended branch tube.

[0007] An inflation-sealing assembly is fixedly installed at the end of the first and second air-guiding pipes and at the middle and end of the extended branch pipes, so as to double-seal the bleeding side or the pneumothorax side lung of the patient with hemopneumothorax through the inflation-sealing assembly.

[0008] Preferably, the top ends of the first air guide pipe and the second air guide pipe are respectively fixedly connected to a first air guide connector and a second air guide connector.

[0009] Preferably, the inflatable sealing assembly includes a first inflatable balloon sleeved and fixed to the outer wall of the end of the first air guide pipe and the second air guide pipe, a second inflatable balloon sleeved and fixed to the outer wall of the middle section of the extension branch pipe, and a third inflatable balloon sleeved and fixed to the inner wall of the end of the extension branch pipe.

[0010] Preferably, the top of the first inflatable bladder is fixedly connected to an outwardly extending inflation hose, and the first inflatable bladder, the second inflatable bladder, and the third inflatable bladder are connected by a connecting hose one and a connecting hose two, respectively.

[0011] Preferably, the first inflatable balloon, the second inflatable balloon, and the third inflatable balloon are all silicone balloons.

[0012] Preferably, the upper part of the third inflatable balloon is coaxially sleeved and fixed to the inner wall of the end of the extension branch pipe, and the lower part of the third inflatable balloon protrudes from the end of the extension branch pipe.

[0013] Preferably, an inflation connector is fixedly connected to the upper end of the inflation hose.

[0014] The aforementioned double-lumen bronchial tube with an internal balloon on the extended bronchus side is used in the resuscitation of patients with hemopneumothorax. When establishing an artificial airway using this double-lumen bronchial tube, the presence of the inflation-sealing assembly—comprising a first inflatable balloon fixed to the outer wall of the ends of the first and second air delivery tubes, a second inflatable balloon fixed to the outer wall of the middle section of the extended bronchus, and a third inflatable balloon coaxially fixed to the inner wall of the end of the extended bronchus—allows the first inflatable balloon to seal the gap between the first and second air delivery tubes and the patient's tracheal wall. Simultaneously, the second and third inflatable balloons provide double occlusion of the bleeding or pneumothorax side of the lung, improving the stability of the occlusion and reducing the risk of complications. This reduces the risk of pulmonary hemorrhage or air leakage. Furthermore, because the top of the first inflatable balloon is fixedly connected to the outwardly extending inflation hose, and the first, second, and third inflatable balloons are connected via connecting hose one and connecting hose two respectively, the first, second, and third inflatable balloons can be sequentially inflated by inflating them through the inflation hose. The inflation method for the first, second, and third inflatable balloons is simple and easy to implement. This facilitates sequential inflation and use of the first, second, and third inflatable balloons, and also allows for subsequent depressurization and removal of the first, second, and third inflatable balloons from the body simply by using the inflation hose.

[0015] The beneficial effects are as follows: 1. The inflatable sealing assembly of this utility model includes a first inflatable balloon sleeved and fixed to the outer wall of the end of the first and second air guide pipes, a second inflatable balloon sleeved and fixed to the outer wall of the middle section of the extension branch pipe, and a third inflatable balloon coaxially sleeved and fixed to the inner wall of the end of the extension branch pipe. In this way, the first inflatable balloon can seal the gap between the first and second air guide pipes and the patient's tracheal wall. At the same time, the second and third inflatable balloons can provide double sealing for the bleeding side or the pneumothorax side of the lung, improving the sealing stability of the bleeding side or the pneumothorax side of the lung and reducing the risk of pulmonary hemorrhage or air leakage.

[0016] 2. The top of the first inflatable balloon is fixedly connected to an outwardly extending inflation hose. The first, second, and third inflatable balloons are connected by connecting hose one and connecting hose two, respectively. The first, second, and third inflatable balloons can be inflated sequentially by inflating them through the inflation hoses. The inflation method of the first, second, and third inflatable balloons is simple and easy to implement. It is convenient to inflate the first, second, and third inflatable balloons sequentially for use. At the same time, it is convenient to depressurize the first, second, and third inflatable balloons sequentially and remove them from the body by simply using the inflation hoses.
