Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a lung isolation device for pediatric hydatid surgery. Background Art

[0002] Because the airway structure and function of children are different from those of adults, the lung isolation technology used in adults cannot be directly copied to children. The management of single-lung ventilation technology in children should be individualized.

[0003] The current technology of single-lung ventilation in children has certain limitations. There are four main types of single-lung ventilation technologies currently used: single-lumen bronchial catheter, double-lumen bronchial catheter, Univent catheter and bronchial occluder. Among them, the single-lumen endobronchial tube is the earliest ventilation method for pediatric lung isolation. A smaller or half-size single-lumen endobronchial tube is inserted into the healthy lung and must be withdrawn to the main airway for suction. It is easy to block the airway and contaminate the healthy lung during surgery for pulmonary hydatid rupture. Double-lumen endobronchial tubes have a large outer diameter and limited catheter models. Currently, the smallest model in my country is 26F, which is suitable for children over 8 years old. The smallest Univent catheter has an inner diameter of 3.5mm, which is equivalent to the outer diameter of a single-lumen tube with ID5.5-6.0mm. It is only suitable for children over 8 years old, and the inner diameter of the Univent catheter's occluder is only 2mm. The pediatric bronchial occluder can pass through a single-lumen tube with ID4.5mm and is suitable for children over 2 years old. The inner diameter of the occluder is 2.3mm, and the lumen is too thin. It is difficult to suction during surgery for pulmonary hydatid rupture, which is not conducive to isolation.

[0004] In summary, it is particularly necessary to design a lung isolation device that can be used for pediatric hydatid surgery. Summary of the invention

[0005] The main purpose of the present application is to provide a lung isolation device for pediatric pulmonary echinococcosis surgery, aiming to solve the above-mentioned technical problems.

[0006] The technical solutions adopted in this application are as follows:

[0007] A lung isolation instrument for pediatric pulmonary echinococcosis surgery comprises an endotracheal tube and a suction tube arranged in parallel, wherein a main air bag is arranged at the front end of the endotracheal tube, a main inflation tube for inflating the main air bag is arranged at the rear end side wall of the endotracheal tube, the inner diameter of the suction tube is 3.33 mm, two side holes are arranged at the front end of the suction tube, a cuff air bag is arranged on the suction tube behind the side holes, an auxiliary inflation tube for inflating the cuff air bag is arranged on the rear end side wall of the suction tube, a sputum suction device pipe joint is connected to the rear end of the suction tube, and a quick-release joint that can be connected to a ventilator is detachably arranged on the sputum suction device pipe joint.

[0008] Optionally, the endotracheal tube and the suction tube are attached to each other.

[0009] Optionally, a shaping guide wire is arranged inside the tube wall of the suction tube.

[0010] Optionally, the quick-release connector includes a soft-pack connector connected to the sputum suction device tube connector and a connector port connected to a ventilator.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] First: The lung isolation device for pediatric pulmonary hydatid surgery proposed in the embodiment of the present application adopts a suction tube with an inner diameter of 3.33mm and is used in conjunction with a tracheal tube. For children under 10 years old who undergo pulmonary hydatid surgery, the lung isolation and lung isolation ventilation can be well performed. The front section of the suction tube has multiple holes for easy suction, and the cuff air bag can play a role in lung isolation. The inner diameter of the tube cavity of 3.33mm is large and not easy to be blocked. It can effectively prevent the cyst fluid and cyst skin from blocking the airway and causing suffocation. It can also prevent the cyst fluid from overflowing and mistakenly entering the healthy lung, contaminating the healthy lung, and reducing the chance of secondary surgery after pulmonary hydatid surgery in children.

[0013] Second: The lung isolation device for pediatric pulmonary echinococcosis surgery proposed in the embodiment of the present application can also be connected to a ventilator by installing a quick-release connector through the suction device tube joint when the lung needs to be re-expanded after the pulmonary echinococcosis is sucked out, and the lung can be inflated without adjusting the position of the tracheal tube, thereby playing the role of a double-lumen bronchial catheter.

[0022] See attached Figure 1The embodiment of the present application provides a lung isolation device for pediatric pulmonary echinococcosis surgery, comprising an endotracheal tube 1 and a suction tube 2. The structure of the suction tube 2 is exactly the same as the structure of the existing sputum suction tube. The endotracheal tube 1 and the suction tube 2 are attached and arranged, and the two have the same bending curvature, similar to a double-lumen endotracheal tube. When performing endotracheal intubation, the endotracheal tube 1 and the suction tube 2 can enter the main airway together, and then the connected and shaped suction tube 2 can be placed into the main bronchus on the affected side by changing the direction of the endotracheal tube 1. Of course, in this embodiment, different endotracheal tube models and lengths of endotracheal tubes are used for children of different age groups. The suction tube lengths corresponding to endotracheal tubes of different lengths are also different. Therefore, the length of the endotracheal tube should be determined according to the length of the trachea and bronchus of different ages, so as to adapt to the use of children with different individual differences. The length of the suction tube 2 is significantly longer than that of the tracheal tube 1, and the front end of the suction tube 2 is located in front of the tracheal tube 1, so that when the suction tube 2 is inserted simultaneously with the tracheal tube 1, the tracheal tube 1 is located in the main airway, and the front end of the suction tube 2 can enter the main bronchus on the affected side.

[0023] Among the above, Figure 1 As shown, a main air bag 101 is arranged on the side wall close to the front end of the tracheal tube 1, a main air-inflating tube 102 for inflating the main air bag 101 is arranged on the rear end side wall of the tracheal tube 1, and a ventilator connector 103 connected to the ventilator is arranged at the rear end of the tracheal tube 1. Two side holes 201 are arranged at the front end of the suction tube 2, and the side holes 201 can be used for suctioning hydatid cysts during surgery. A cuff air bag 202 is arranged on the suction tube 2 behind the side holes 201, and an auxiliary air-inflating tube 203 for inflating the cuff air bag 202 is arranged on the rear end side wall of the suction tube 2. A sputum suction device pipe joint 204 is connected to the rear end of the suction tube 2, and the sputum suction device joint is connected to the sputum suction device. During the operation, the endotracheal tube 1 and the suction tube 2 can enter the main airway together, and the connected and shaped suction tube 2 is placed into the main bronchus on the affected side by changing the direction of the endotracheal tube 1. Then the endotracheal tube 1 is connected to the ventilator, and the main airbag 101 and the cuff airbag 202 are inflated. The main airbag 101 blocks the main airway, and the cuff airbag 202 blocks the bronchial tube of the affected lung to prevent the cyst fluid from overflowing during the pulmonary hydatid surgery and accidentally entering the healthy lung to contaminate the healthy lung. The suction tube 2 is connected to the sputum suction device to complete the suction of the pulmonary hydatid surgery.

[0024] In this embodiment, the sputum suction device pipe joint 204 is detachably provided with a quick-release joint 205 that can be connected to a ventilator. Figure 1As shown, the quick-release connector 205 includes a soft-pack connector connected to the suction device pipe connector 204 and a connector port connected to the ventilator. The soft-pack connector has a certain shape and can be tightly sleeved on the pagoda connector of the suction device pipe connector 204. The connector port is a conventional interface shape connected to the ventilator. It is not difficult to imagine that when performing a lung hydatid suction operation, the suction device pipe connector 204 is connected to the suction device to complete the lung hydatid suction. After the suction is completed, when the lung needs to be re-expanded, the quick-release connector 205 is tightly sleeved on the suction device pipe connector 204 and connected to the ventilator. The affected lung is inflated through the ventilator to complete the lung expansion operation, which is practical and convenient.

[0025] In a preferred embodiment, since the suction tube 2 is relatively thin and difficult to insert into the respiratory tract, Figure 2 As shown, a shaping guide wire 206 is arranged inside the tube wall of the suction tube 2. The shaping guide wire 206 can enhance the hardness of the suction tube 2 to a certain extent, so that it can be inserted into the respiratory tract more easily to complete the surgical suction of pulmonary hydatid disease.

[0026] In summary, the lung isolation device for pediatric pulmonary hydatid surgery provided in the embodiments of the present application has the following advantages:

[0027] First: The lung isolation device for pediatric pulmonary hydatid surgery proposed in the embodiment of the present application adopts a suction tube with an inner diameter of 3.33mm and a breathing tube for use. For children under 10 years old undergoing pulmonary hydatid surgery, single-lung ventilation technology can be well performed and lung isolation can be performed. The front section of the suction tube has multiple holes for easy suction, and there is a cuff air bag that can play a role in lung isolation. The inner diameter of the tube cavity of 3.33mm is relatively large and not easy to be blocked. It can effectively prevent the cyst fluid and cyst skin from blocking the airway and causing suffocation. It can also prevent the cyst fluid from overflowing and mistakenly entering the healthy lung, contaminating the healthy lung, and reducing the probability of secondary surgery after pulmonary hydatid surgery in children.

[0028] Second: The lung isolation device for pediatric pulmonary echinococcosis surgery proposed in the embodiment of the present application can also be connected to a ventilator by installing a quick-release connector through the suction device tube joint when the lung needs to be re-expanded after the pulmonary echinococcosis is sucked out, and the lung can be inflated without adjusting the position of the tracheal tube, thereby playing the role of a double-lumen bronchial catheter.

[0029] Third: The lung isolation device for pediatric pulmonary echinococcosis surgery proposed in the embodiment of the present application greatly solves the problem of individual differences caused by children's growth and development by determining the different usage lengths of the suction tube according to the lengths of the trachea and bronchi at different ages.

[0030] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
