DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 5 The utility model provides a technical solution: a novel chest drainage device, including a drainage tube 2 and a drainage tube 3, the drainage tube 2 and one end of the drainage tube 3 are connected through a pipeline connection assembly 1, the pipeline connection assembly 1 includes an upper tube body 101 connected to one end of the drainage tube 2 and a lower tube body 102 connected to one end of the drainage tube 3, a spare branch pipe 103 is connected on the outer wall of one side of the upper tube body 101, a limited boss 114 is provided on the inner wall of the opening at one end of the upper tube body 101, a threaded groove 109 is provided on the inner wall of the circle around the limited boss 114, and a threaded groove 109 is provided on the inner wall of the circle around the limited boss 114. A supporting connection part 110 is provided at the mouth, and a thread 111 is provided on the outer wall around the supporting connection part 110, and is threadedly connected to the thread groove 109 through the thread 111. A sealing ring is slidably connected between the inner walls around the upper tube body 101. When the lower tube body 102 is connected to the upper tube body 101, the sealing ring can cover the connection between the spare branch pipe 103 and the upper tube body 101. When the lower tube body 102 is separated from the upper tube body 101, the sealing ring falls to the top surface of the limiting boss 114, exposing the connection between the spare branch pipe 103 and the upper tube body 101. The other end of the guide tube 3 is connected to the drainage bag 4.
[0024] See also Figure 4 The sealing ring includes a ring body 105, the outer wall diameter of the ring body 105 is consistent with the inner wall diameter of the upper tube body 101, and a plurality of fan-shaped closed blades 106 distributed in an annular shape are arranged inside the ring body 105. One end of each closed blade 106 is rotatably connected to the inner wall of the ring body 105. When all the closed blades 106 are closed, a complete cone can be formed. One end of the ring body 105 is provided with an abutment portion 108 that cooperates with the top holding connection portion 110.
[0025] When the lower tube body 102 is connected as a whole through the cooperation of the thread groove 109 and the thread 111, the supporting connection part 110 extends to the interior of the upper tube body 101 and pushes the ring body 105 upward. At this time, the outer wall of the ring body 105 blocks the connection between the spare branch pipe 103 and the upper tube body 101. The liquid entering the upper tube body 101 from the drainage tube 2 will pass through the ring body 105 and then enter the lower tube body 102, and enter the guide tube 3 from the lower tube body 102 and finally enter the drainage bag 4 for storage.
[0026] Furthermore, a guide portion 107 inclined toward the inside is provided at the other end of the ring body 105 .
[0027] By providing the guide portion 107 , the body fluid can flow downward along the inner wall of the upper tube body 101 to the inside of the ring body 105 , thereby smoothly passing through the ring body 105 , thereby reducing the accumulation of body fluid on the top surface of the ring body 105 .
[0028] Furthermore, a bracket 112 is fixedly connected between the inner walls of the supporting connection portion 110 , and one end of the bracket 112 is connected to a propping piece 113 that cooperates with a plurality of closed blades 106 .
[0029] When the supporting connection part 110 is located inside the upper tube body 101 and lifts the ring body 105, the opening member 113 is inside the ring body 105, and the opening member 113 circumferentially pushes the plurality of closed blades 106 upward, so that gaps are formed between the plurality of closed blades 106, and the body fluid entering the ring body 105 can smoothly flow through the ring body 105 into the lower tube body 102. When the lower tube body 102 is separated from the upper tube body 101, the ring body 105 that loses the supporting part slides downward and is clamped on the upper end of the limiting boss 114, so that the spare branch pipe 103 is connected to the upper tube body 101. The closed blades 106 also lose the support of the propping piece 113, and thus fall back to the initial position to be spliced into a complete cone. At this time, the body fluid entering the upper tube body 101 can no longer pass through the ring body 105, and instead flows out of the upper tube body 101 from the spare branch pipe 103, and is temporarily collected by other containers until a new drainage bag 4 is replaced and the ring body 105 is lifted up again by the supporting connection part 110. This ensures that when the drainage bag 4 is replaced, the body fluid will not leak out from the bottom end of the upper tube body 101 to cause environmental pollution, thereby reducing limitations in use.
[0030] Furthermore, the support member 113 is rotatably connected to one end of the bracket 112 .
[0031] In actual use, in order to increase the area for body fluids to pass through, a number of slits can be set on the expansion piece 113. By rotatably installing the expansion piece 113 on one end of the bracket 112, it can be avoided that when the lower tube body 102 is rotated to connect with the upper tube body 101, the edge of the slit on the expansion piece 113 and the edge of the closed blade 106 will interfere with each other in movement, resulting in unsmooth rotation.
[0032] See also Figure 1 and Figure 2 A threaded groove is provided on the inner wall of one end of the spare branch pipe 103, and the branch pipe cover 104 is threadedly connected through the threaded groove.
[0033] By setting a branch tube cover 104 at one end of the spare branch tube 103, foreign matter can be prevented from entering the spare branch tube 103 and causing blockage of the spare branch tube 103, thereby improving stability during use. When temporarily collecting body fluids through the spare branch tube 103, the branch tube cover 104 can be removed.
[0034] Furthermore, a drainage tube 5 is provided at the bottom of the drainage bag 4 , and a sealing cap is threadedly connected to one end of the drainage tube 5 .
[0035] When the body fluid collected in the drainage bag 4 needs to be discharged, the sealing cover can be removed through the drainage tube 5 for discharge.
[0036] Furthermore, a capacity mark is provided on one side surface of the drainage bag 4 .
[0037] By setting the capacity mark, medical personnel can conveniently observe the amount of body fluid collected and thus judge the patient's condition.
[0038] Working principle: insert the supporting connection part 110 into the limiting boss 114, and rotate the lower tube 102 to complete the connection between the upper tube 101 and the lower tube 102 through the cooperation of the thread groove 109 and the thread 111. At this time, the supporting connection part 110 supports the abutment part 108 at the bottom end of the ring body 105 upward, so that the ring body 105 as a whole moves upward inside the upper tube 101, thereby blocking the connection between the spare branch pipe 103 and the upper tube 101. At the same time, the bracket 112 is located inside the ring body 105, and the plurality of closed leaves 106 are lifted up by the propping piece 113 to form gaps between the plurality of closed leaves 106. After the body fluid enters the upper tube 101 from the drainage tube 2, it enters the ring body 105, passes through the gaps between the plurality of closed leaves 106, and enters the lower tube 10 2, and finally enters the drainage bag 4 through the guide tube 3 for storage. When the body fluid in the drainage bag 4 accumulates to a certain extent or the drainage bag 4 is damaged and needs to be replaced, the lower tube body 102 is rotated in the opposite direction again to separate the lower tube body 102 from the upper tube body 101. At this time, 105, which has lost the support of the supporting connection part 110, falls back to the upper end of the limiting boss 114, exposing the connection between the spare branch tube 103 and the upper tube body 101. At the same time, a number of closing blades 106 lose the support of the propping part 113 and are reset to form a complete cone again, thereby closing the ring body 105, so that the body fluid cannot flow out from the bottom end of the upper tube body 101 and instead flows out of the upper tube body 101 through the spare branch tube 103. At this time, the branch tube cover 104 can be opened to temporarily collect the body fluid through other containers until a new drainage bag 4 is replaced.
[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
