[0033] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a critical care suction tube, which includes a suction tube body 1. One end of the suction tube body 1 is an insertion end for inserting into the patient's respiratory tract, and the other end of the suction tube body 1 is a connection end connected to a negative pressure generating assembly. A head 2 with a smooth surface is connected to the insertion end of the suction tube body 1. A suction hole 4 is formed on the side wall of the insertion end of the suction tube body 1. A connector 3 is provided at the connection end of the suction tube body 1. By arranging the suction hole 4 on the side wall of the insertion end of the suction tube body 1, compared with the traditional suction tube where the suction hole 4 is arranged on the end face of the insertion end of the suction tube body 1, the phenomenon that the edges and corners at the opening of the suction hole 4 scratch the patient's respiratory tract can be effectively avoided. In addition, the head 2 with a smooth surface is arranged at the insertion end of the suction tube body 1, which can effectively avoid the phenomenon that the edges and corners of the end face of the insertion end of the suction tube body 1 scratch the patient's respiratory tract when the suction tube body 1 is inserted into the patient's respiratory tract, making it safer and more reliable.
[0034] As Figure 1 and Figure 2As shown, the sputum suction holes 4 are distributed in a strip shape along the length direction of the sputum suction tube body 1, and a plurality of sputum suction holes 4 are provided around the sputum suction tube body 1, which is beneficial to sucking out the sputum in the patient's respiratory tract.
[0035] As Figure 2 and Figure 3 shown, the end head 2 is a hemispherical block 10 connected to the insertion end of the sputum suction tube body 1, and the diameter of the hemispherical block 10 is the same as the outer diameter of the sputum suction tube body 1. By selecting the hemispherical block 10 as the end head 2, it is beneficial for the insertion end of the sputum suction tube body 1 to be smoothly inserted into the patient's respiratory tract and can avoid scratching the patient's respiratory tract.
[0036] As Figure 2 and Figure 4 shown, the end head 2 is a sphere 11 connected to the insertion end of the sputum suction tube body 1, and the diameter of the sphere 11 is larger than the outer diameter of the sputum suction tube body 1. By selecting the sphere 11 as the end head 2, it is beneficial for the insertion end of the sputum suction tube body 1 to be smoothly inserted into the patient's respiratory tract, and at the same time, the respiratory tract can be expanded to prevent the edges and corners at the opening of the sputum suction holes 4 from scratching the patient's respiratory tract wall and causing damage.
[0037] As Figure 1 and Figure 2 shown, the connection head 3 is a connection sleeve 5 provided at the connection end of the sputum suction tube body 1 for connecting with a negative pressure generating component. A convex rib 6 is provided on the outer wall of the connection sleeve 5. The setting of the convex rib 6 can facilitate the nursing staff to hold the connection sleeve 5 and connect it with the negative pressure generating component.
[0038] As Figure 1 , Figure 2 and Figure 5As shown, a tee joint 7 is provided between the sputum suction tube body 1 and the connecting sleeve 5. The tee joint 7 has two horizontally aligned interfaces and a sputum drainage tube 8 at the bottom. The two interfaces of the tee joint 7 are respectively connected to the sputum suction tube body 1 and the connecting sleeve 5. A sputum storage bottle 9 is connected to the sputum drainage tube 8. A liquid-blocking and air-permeable membrane 12 is provided inside the tee joint 7. The liquid-blocking and air-permeable membrane 12 is located on the side of the sputum drainage tube 8 away from the sputum suction tube body 1. A pair of tongue valves 13 are provided inside the sputum drainage tube 8. The pair of tongue valves 13 are used to close the sputum storage bottle 9 inside the sputum drainage tube 8 in the direction towards the sputum suction tube body 1 and the connecting sleeve 5. Through this structural method, when the negative pressure generating component connected to the connecting sleeve 5 performs a suction action once, the pair of tongue valves 13 in the sputum drainage tube 8 close to prevent the air in the sputum storage bottle 9 from being sucked out. At this time, negative pressure is generated inside the sputum suction tube body 1, and the sputum in the patient's respiratory tract is inhaled into the sputum suction tube body 1 through the sputum suction hole 4. After the sputum is sucked into the tee joint 7, the negative pressure generating component completes a suction action, and the liquid-blocking and air-permeable membrane 12 blocks the flow of the sputum towards the connecting sleeve 5. Then the sputum flows into the sputum drainage tube 8 and is discharged into the sputum storage bottle 9 through the pair of tongue valves 13 for collection. Thus, when the negative pressure generating component sucks air at intervals, the sputum in the patient's respiratory tract can be continuously sucked into the sputum storage bottle 9 for storage. Compared with the method in traditional sputum suction devices where the sputum storage structure is arranged on the negative pressure generating component, it can avoid the phenomenon that the sputum flows towards the negative pressure generating component and pollutes the pressure generating component, thereby saving the maintenance cost of the negative pressure generating component and reducing the cost of sputum suction care.
[0039] As Figure 1 , Figure 2 and Figure 5 shown, the sputum storage bottle 9 includes a bottle body 15 and a bottle cap 16. The sputum drainage tube 8 is connected to the bottle cap 16 and penetrates through the bottle cap 16. The bottle body 15 is screwed and sealed with the bottle cap 16, which is convenient for sampling the sputum in the sputum storage bottle 9 for sputum inspection. The sputum drainage tube 8 is inclined and distributed towards the connecting sleeve 5. A liquid receiving groove 14 is opened at the connection between the inner wall of the tee joint 7 and the sputum drainage tube 8. The liquid-blocking and air-permeable membrane 12 is inclined and distributed towards the sputum drainage tube 8. Through this structural method, during the sputum suction process, it is beneficial for the sputum to flow into the sputum storage bottle 9 for collection.
[0040] The working principle of the technical solution provided by the present utility model is as follows:
[0041] During use, it is connected to the negative pressure generating component by means of the connecting sleeve 5. The insertion end of the sputum suction tube body 1 is inserted into the patient's respiratory tract. After the negative pressure generating component generates negative pressure, the sputum in the patient's respiratory tract is inhaled into the sputum suction tube body 1 through a plurality of sputum suction holes 4 opened on the side wall of the insertion end of the sputum suction tube body 1. When the sputum is sucked to the three-way joint 7, due to the blocking of the liquid by the liquid-blocking and air-permeable membrane 12, the sputum falls into the liquid storage tank 14 and flows into the sputum discharge tube 8. Subsequently, the sputum flows into the sputum storage bottle 9 through the gap between a pair of tongue flaps 13 for collection, achieving sputum suction care for the patient. Since the sputum suction holes 4 are opened on the side wall of the insertion end of the sputum suction tube body 1, compared with the traditional sputum suction tube where the sputum suction holes 4 are opened on the end face of the insertion end of the sputum suction tube body 1, it can effectively avoid the phenomenon of scratching the patient's respiratory tract by the edges and corners at the opening of the sputum suction holes 4. In addition, the insertion end of the sputum suction tube body 1 is provided with a head 2 having a smooth surface, which can effectively avoid the phenomenon of scratching the patient's respiratory tract by the edges and corners of the end face of the insertion end of the sputum suction tube body 1 when the sputum suction tube body 1 is inserted into the patient's respiratory tract, being safer and more reliable.
[0042] The present utility model covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. Additionally, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0043] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
