Technical Field
[0001] The utility model belongs to the field of medical instruments, and in particular relates to a chest drainage tube which can be quickly blocked. Background Art
[0002] A chest drainage tube is a pipe used to drain the accumulated air or fluid in the chest cavity, and is widely used in the treatment of diseases such as pneumothorax and hemothorax. In clinical practice, when a chest drainage tube is used, air may enter the patient's chest cavity due to the tipping of the chest bottle, the loosening of the chest tube, or its unplanned detachment, causing pneumothorax, threatening the patient's life safety. Therefore, in special cases, the chest drainage tube needs to be urgently blocked to prevent air from entering the tube. In the prior art, hemostatic forceps are mainly used to fold the drainage tube and cross-clamp it. In actual operation, it is necessary to first find an instrument and then perform secondary clamping to complete the blocking. There are problems such as long time consumption and cumbersome operation. During the operation, the blocking will fail due to problems such as insufficient clamping force and loosening of tools. In the case of every second, these problems will further aggravate the patient's degree of danger. Therefore, a chest drainage tube that can be quickly blocked and easy to operate is urgently needed. Utility Model Content

[0021] For the convenience of understanding by those skilled in the art, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] As Figure 1 shown, a thoracic drainage tube capable of rapid blocking includes a drainage tube 100, and is characterized in that: an inner airbag 110 is arranged inside the drainage tube 100, when the inner airbag 110 expands, it fills and blocks the drainage tube 100, the inner airbag 110 is connected to an air tube 120, the air tube 120 is connected to an outer airbag 130, the wall of the drainage tube 100 is connected to a connecting tube 140, the connecting tube 140 is used to connect a syringe or an infusion tube, and clamping members 150 for controlling the on-off of the pipeline are arranged on both the air tube 120 and the connecting tube 140.
[0023] As shown Figure 1 , 2 , as shown in FIG. 3, an inner airbag 110 is provided in the drainage tube 100. When the inner airbag 110 expands, it is annular and fills and blocks the drainage tube 100, preventing air from entering the patient's thoracic cavity through the drainage tube 100, achieving the blocking purpose. When the inner airbag 110 is in a contracted state, it fits annularly against the inner wall of the drainage tube 100, and the drainage tube 100 is not blocked and can drain normally.
[0024] As shown Figure 1 , 4 , as shown in FIG. 5, the inner airbag 110 is connected to an air tube 120, and the air tube 120 is connected to an outer airbag 130. The inner airbag 110 and the outer airbag 130 are connected through the air tube 120. Squeezing the outer airbag 130 can cause the air in the outer airbag 130 to flow into the inner airbag 110, causing the inner airbag 110 to expand and block the drainage tube 100, achieving the blocking purpose. A clamping member 150 is provided on the air tube 120, and the clamping member 150 is provided with a circular hole portion and a clamping groove that communicate with each other. In the drainage state, the clamping groove of the clamping member 150 clamps on the air tube 120, and the air tube 120 is in a closed state due to being squeezed, and the gas in the outer airbag 130 cannot enter the inner airbag 110, and the inner airbag 110 remains in a contracted state. When performing the blocking operation, the circular hole portion of the clamping member 150 is pushed to the air tube 120. At this time, the air tube 120 is not squeezed, and the gas in the inner airbag 110 and the outer airbag 130 can flow through the air tube 120. Squeezing the outer airbag 130 can cause the inner airbag 110 to become an expanded state.
[0025] The outer airbag 130 is made of an elastic material. In the normal state, the negative pressure generated by the elasticity of the outer airbag 130 will keep it in a gas storage state, while the inner airbag 110 is in a contracted state. After the blocking operation, the inner airbag 110 becomes an expanded state. If it is necessary to restore the contracted state, the circular hole portion of the clamping member 150 can be pushed to the air tube 120 to keep the air tube 120 in an open state. The negative pressure generated by the elasticity of the outer airbag 130 will suck the air in the inner airbag 110 back, causing the inner airbag 110 to restore the contracted state, so that the drainage tube 100 can continue to drain normally.
[0026] As shown Figure 1As shown, a connecting tube 140 is connected to the wall of the drainage tube 100. The connecting tube 140 is used to connect a syringe or an infusion tube, and an external syringe or infusion tube can be used to flush the inside of the drainage tube 100. One end of the connecting tube 140 for connecting the syringe and the infusion tube is provided with a one-way infusion joint 141, which is convenient for connection and can keep the connecting tube 140 in a positive pressure state to prevent air and liquid from flowing back. The connection part of the connecting tube 140 and the drainage tube 100 is arranged between the inner airbag 110 and the drainage opening of the drainage tube 100. The connecting tube 140 and the trachea 120 are located on opposite sides of the drainage tube 100. During the flushing process, the cleaning liquid can flush the inner airbag 110 to keep the drainage tube 100 and the inner airbag 110 clean and reduce the infection probability of the patient.
[0027] A clamping member 150 is provided on the connecting tube 140. The clamping member 150 is provided with a circular hole part and a clamping groove that are connected. In the drainage state, the clamping groove of the clamping member 150 is clamped on the connecting tube 140. In the case of not connecting a syringe and an infusion tube, the air and liquid led out by the drainage tube 100 cannot flow out through the connecting tube 140, avoiding environmental pollution and preventing air from entering at the same time. During flushing, the connecting tube 140 is connected to a syringe or an infusion tube, and the circular hole part of the clamping member 150 is pushed onto the connecting tube 140. The connecting tube 140 is in an open state, and then flushing is carried out.
[0028] A fixing member 160 is provided on the drainage tube 100. The fixing member 160 is arranged at a position 10 cm from the drainage opening end of the drainage tube 100. The fixing member 160 is plate-shaped. Through holes 161 are opened on both the left and right sides of the fixing member 160. A guide core 101 is arranged inside the drainage tube 100. Since the drainage tube 100 is made of a soft material, it is difficult to align the corresponding position when inserting it into the patient's chest cavity. The guide core 101 can facilitate the insertion of the drainage tube 100 to the correct position. After the drainage opening of the drainage tube 100 is inserted into the patient's chest cavity, the fixing member 160 is used to press and buckle the drainage tube 100 outside the patient, and the fixing member 160 is sewn to the patient's body by using a suture passing through the through hole 161 to fix the drainage tube 100. The fixing member 160 is arranged at the near-drainage opening section of the drainage tube 100, which is convenient for better fixing the drainage opening.
[0029] Operation process: Before drainage, insert the drainage opening of the drainage tube 100 into the patient's thoracic cavity, use the fixing member 160 to press and fasten the drainage tube 100 outside the patient, and use a suture to pass through the through hole 161 to sew and fix the fixing member 160 outside the patient to fix the drainage tube 100. During drainage, keep the clamping groove of the clamping member 150 clamped on the trachea 120, and the inner airbag 110 remains in a contracted state. During the blocking operation, move the circular hole portion of the clamping member 150 to the trachea 120, squeeze the outer airbag 130 so that the air flows into the inner airbag 110, and the inner airbag 110 becomes in an inflated state, filling and blocking the drainage tube 100 to achieve the blocking purpose. After the blocking is successful, move the clamping groove of the clamping member 150 back to be clamped on the trachea 120 to prevent the gas in the inner airbag 110 from flowing out and maintain the blocking effect. Subsequently, other medical operations can be performed. When restoring the drainage state, move the circular hole portion of the clamping member 150 to the trachea 120 to keep the trachea 120 in an open state, and the outer airbag 130 sucks the gas in the inner airbag 110 back, and the inner airbag 110 returns to the contracted state, and the drainage tube 100 can continue to drain.
[0030] During the drainage state, keep the clamping groove of the clamping member 150 clamped on the connecting tube 140. When performing the flushing operation, move the circular hole portion of the clamping member 150 to the connecting tube 140, connect the connecting tube 140 to a syringe or an infusion tube, and use the syringe to flush the inside of the drainage tube 100.
[0031] The above embodiments are the preferred implementation manners of the present invention, and are not intended to limit the present invention. Without departing from the inventive concept of the present invention, any obvious replacement is within the protection scope of the present invention.
