[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will combine the utility model specific embodiment and corresponding drawings to make the utility model technical scheme clear and complete. Obviously, the described embodiment is only a part of the utility model embodiment, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the utility model protection.
[0023] The following will combine the drawings, and the technical scheme provided by each embodiment of the utility model will be described in detail.
[0024] The utility model embodiment provides a kind of indwelling stomach tube tube sealing structure, including being used for the sealing of stomach tube body 1 opening end for the blocking piece 2 of stomach tube body 1, the blocking piece 2 includes the plug 21 for entering into the opening end of stomach tube body 1 and the fixed cap 22 being movably connected with plug 21, plug 21 extends from the both ends of fixed cap 22 and does not fall, fixed cap 22 is threadedly connected with the opening end of stomach tube body 1, when the stomach tube body 1 is sealed, first, two fingers can be buckled buckle 3, then the end of plug 21 is pressed, plug 21 is pressed to the port inside of stomach tube body 1, then fixed cap 22 is rotated, and fixed cap 22 is threadedly connected with the outer wall of stomach tube body 1, and when fixed cap 22 is threadedly connected to the terminal point of screw groove, the end wall of fixed cap 22 and the end surface of plug 21 are in abutment, so as to avoid the falling of plug 21 due to the increase of internal pressure of stomach tube body 1 and other reasons, improve the effect of stabilizing, and, preliminary positioning mechanism is arranged between plug 21 and the opening end of stomach tube body 1, after plug 21 is inserted into the port of stomach tube body 1, plug 21 is preliminarily fixed with the port of stomach tube body 1 by preliminary positioning mechanism, so that plug 21 does not separate from stomach tube body 1 when fixed cap 22 is rotated subsequently, this installation process can be operated by single hand, more convenient for medical staff to operate;
[0025] Preferably, the primary positioning mechanism comprises a ring-shaped protrusion 4 arranged on the inner wall of the open end of the gastric tube body 1 and a ring-shaped groove 41 arranged on the outer wall of the plug 21 and corresponding to the ring-shaped protrusion 4, and the ring-shaped protrusion 4 can be made of elastic materials such as silica gel. When the plug 21 enters the port of the gastric tube body 1, the ring-shaped protrusion 4 first comes into contact with the outer wall of the plug 21 and deforms. When the ring-shaped protrusion 4 enters the ring-shaped groove 41, the ring-shaped protrusion 4 is no longer subjected to the contact force of the outer wall of the plug 21, thereby restoring the deformation and being clamped in the ring-shaped groove 41. The plug 21 is thus primarily fixed inside the port, and a seal is formed between the plug 21 and the port of the gastric tube body 1, reducing the entry of external air into the gastric tube body 1. Conversely, when the plug of the gastric tube body 1 is removed, the fixing cap 22 is first disconnected from the gastric tube body 1, and then the fixing cap 22 is pulled away from the gastric tube body 1, so that the fixing cap 22 drives the plug 21 to be disconnected from the port of the gastric tube body 1, thereby removing the seal of the gastric tube body 1.
[0026] Preferably, the diameter of the plug 21 gradually decreases from the fixing cap 22 to the open end of the gastric tube body 1, i.e., the cross-sectional area of the end of the plug 21 close to the gastric tube body 1 is small, so that the plug 21 can be more accurately inserted into the port of the gastric tube body 1.
[0027] Preferably, a connecting strap 5 is connected to the outer wall of the gastric tube body 1, and the other end of the connecting strap 5 is movably connected to the fixing cap 22 through a connecting buckle. The connecting strap 5 connects the sealing member 2 and the gastric tube body 1, avoids the random placement of the sealing member 2, and reduces the risk of loss. The connecting buckle can rotate along the axis of the fixing cap 22, and the connecting strap 5 is prevented from being knotted and entangled when the fixing cap 22 is rotated.
[0028] Preferably, a flexible bandage 6 is connected to the fixing cap 22, and the flexible bandage 6 can fix one end of the gastric tube body 1 to a bed or a patient's hospital gown through the sealing member 2, thereby avoiding the random swinging of the one end of the gastric tube body 1 and reducing the risk of falling off.
[0029] Preferably, the end surface area of the fixing cap 22 away from the open end of the gastric tube body 1 is smaller than the end surface area of the plug 21, i.e., part of the end of the plug 21 is not blocked by the fixing cap 22, thereby facilitating the pressing of the plug 21.
[0030] The above description is only an embodiment of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
