Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anti-falling stomach tube connector. Background Art

[0002] Gastrointestinal decompression is a procedure that uses the principles of negative pressure suction and siphoning. One end of a gastric tube is inserted from the oral or nasal cavity, and the other end of the gastric tube is connected to a drainage tube and a negative pressure pot that is subsequently connected to the drainage catheter. The gas and liquid accumulated in the gastrointestinal tract are sucked out through the gastric tube. For patients with gastrointestinal obstruction, it can reduce the pressure and expansion of the gastrointestinal tract. For patients with gastrointestinal perforation, it can prevent gastrointestinal contents from continuing to leak into the abdominal cavity through the rupture, and is conducive to the healing of anastomosis after gastrointestinal anastomosis. Therefore, it has a wide range of applications and is often used in acute gastric dilatation, intestinal obstruction, repair or partial resection of gastrointestinal perforation, and after bile duct or pancreatic surgery.

[0003] The connection and disconnection between the gastric tube and the drainage tube are usually achieved through a gastric tube connector, specifically, one end of the gastric tube outside the body is connected to one end of the gastric tube connector. When the drainage catheter is needed, the other end of the drainage catheter is inserted into the gastric tube connector and sleeved on the outside of the connecting sleeve connected to the gastric tube. When the drainage catheter is not needed, the other end of the gastric tube connector is blocked with a sealing plug on the gastric tube connector to prevent air from entering the human body through the gastric tube. However, in order to facilitate the sleeve connection of the drainage tube, the outer wall of the existing connecting sleeve is usually a smooth cylindrical surface, and the drainage catheter is easily detached from the outside of the connecting sleeve, resulting in the disconnection of the gastric tube and the drainage catheter, and leakage of the drainage in the gastric tube. In this regard, medical staff often wrap adhesive tape around the outside of the tube mouth of the drainage catheter, and then insert the drainage catheter into the stomach tube connector and sleeve it over the connecting sleeve. At this time, the adhesive tape will fill the gap between the drainage catheter and the inner wall of the stomach tube connector, thereby increasing the friction between the outer wall of the drainage catheter and the inner wall of the stomach tube connector, preventing the drainage catheter from falling off the connecting sleeve. However, wrapping the adhesive tape prolongs the preparation time for daily replacement of the drainage catheter and performing gastrointestinal decompression on the patient, and when too much adhesive tape is wrapped, the friction between the outer wall of the drainage catheter and the inner wall of the stomach tube connector will cause the drainage catheter to be unable to penetrate smoothly into the stomach tube connector, thereby affecting the sleeve connection of the drainage catheter and the connecting sleeve. Utility Model Content

[0004] The technical problem to be solved by the utility model is to study an anti-falling stomach tube joint, which is easy to operate and prevents the drainage catheter from falling off from the tube opening of the connecting sleeve.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A gastric tube connector that prevents falling off comprises a gastric tube connector body, a connecting sleeve inside the gastric tube connector body being provided with a plurality of grooves along the circumference, a shell of the gastric tube connector body being provided with through holes corresponding to the plurality of grooves, a limiting column being inserted into each through hole, and a front end of the limiting column being an arc surface matching the groove.

[0007] The beneficial effects of the utility model are as follows: the drainage catheter is sleeved on the connecting sleeve to communicate with the stomach tube, the tube mouth of the drainage catheter passes through the groove, and then the limiting column is pushed inward from the through hole, so that the limiting column is pressed into the groove, and the limiting column presses the drainage catheter outside the groove against the connecting sleeve. The side wall of the drainage catheter between the groove and the limiting column has an arc-shaped cross-section due to the presence of the groove, and has a large contact area with the front end arc surface of the limiting column, thereby increasing the friction between the drainage catheter and the limiting column, and effectively preventing the drainage catheter from falling off the connecting sleeve. Since the drainage catheter is a hose and has a certain elasticity, the groove does not affect the passage of the drainage catheter, and at the same time, it realizes the clamping of the drainage catheter with the limiting column, effectively preventing the drainage catheter from falling off. The stomach tube joint has a simple structure. After the drainage catheter is sleeved on the outside of the connecting sleeve, it only needs to press the limiting column to fix the drainage catheter. It is easy to operate, has a good anti-falling effect, and does not require other auxiliary materials, and can be reused.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a limiting ring, which is fixedly arranged in the through hole, and two limiting rings adapted to the limiting ring are arranged outside the limiting column at intervals, and both the limiting ring and the limiting ring are made of rubber.

[0010] Furthermore, a handle is provided at the rear end of the limiting column.

[0011] Furthermore, the shell is made of transparent plastic.

[0012] Furthermore, a sealing plug is connected to the outside of the shell through a silicone rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figures 1 to 6 As shown, embodiment 1 of the utility model is an anti-falling gastric tube connector, comprising a gastric tube connector body 1, a connecting sleeve 11 inside the gastric tube connector body 1 is provided with a plurality of grooves 111 along the circumference, a shell 12 of the gastric tube connector body 1 is provided with through holes 121 corresponding to the plurality of grooves 111, a limiting column 2 is inserted into each through hole 121, and the front end of the limiting column 2 is an arc surface matching the groove 111.

[0023] The drainage catheter 4 is sleeved on the connecting sleeve 11 to communicate with the gastric tube 5, the tube mouth of the drainage catheter 4 passes through the groove 111, and then the limiting column 2 is pushed inward from the through hole 121, so that the limiting column 2 is pressed into the groove 111, and the limiting column 2 presses the drainage catheter 4 outside the groove 111 against the connecting sleeve 11. The side wall of the drainage catheter 4 between the groove 111 and the limiting column 2 has an arc-shaped cross-section due to the existence of the groove 111, and has a large contact area with the front end arc surface of the limiting column 2, thereby increasing the friction between the drainage catheter 4 and the limiting column 2, and effectively preventing the drainage catheter 4 from falling off from the connecting sleeve 11. Since the drainage catheter 4 is a soft tube with a certain elasticity, the groove 111 does not affect the passage of the drainage catheter 4, and at the same time, it realizes the clamping of the drainage catheter 4 with the limiting column 2, effectively preventing the drainage catheter 4 from falling off. The stomach tube connector has a simple structure. After the drainage catheter 4 is sleeved on the outside of the connecting sleeve 11, the drainage catheter 4 can be fixed by pressing the limiting column 3. It is easy to operate and has a good anti-falling effect. It does not require other auxiliary materials and can be reused.

[0024] Embodiment 2 of the utility model is an anti-falling gastric tube connector. On the basis of embodiment 1, it also includes a limiting ring 3. The limiting ring 3 is fixedly arranged in the through hole 121. Two limiting rings 21 adapted to the limiting ring 3 are arranged outside the limiting column 2 at intervals. Both the limiting ring 21 and the limiting ring 3 are made of rubber. When the limit column 2 is pushed into the shell 12, the limit ring 21 at the rear end of the limit column 2 passes through the limit ring 3 under the action of external force. When the external force is removed, the limit ring 3 presses against the limit ring 21 at the rear end, thereby ensuring that the limit column 2 presses against the drainage catheter 4; when the limit column 2 is pulled out, the limit ring 21 at the rear end of the limit column 2 withdraws from the limit ring 3 under the action of external force. When the limit ring 21 at the rear end withdraws from the limit ring 3, the external force is removed, and the limiting effect of the limit ring 3 on the limit ring 21 at the front end of the limit column 2 can prevent the limit column 2 from falling from the shell 12; this structure has a good limiting effect on the limit column 2 and is easy to operate.

[0025] Embodiment 3 of the utility model is a stomach tube connector that prevents falling off. On the basis of embodiment 2, the rear end of the limiting column 2 is provided with a handle 22. It is convenient to pull out the limiting column 2, which is more labor-saving.

[0026] Embodiment 4 of the present invention is a stomach tube connector that prevents falling off. Based on embodiment 1, the housing 12 is made of transparent plastic material. The transparent material can facilitate medical personnel to observe the connection status in the housing 1 and make timely adjustments if abnormalities are found.

[0027] Embodiment 5 of the utility model is a stomach tube connector that prevents falling off. Based on any one of embodiments 1 to 4, a sealing plug 7 is connected to the outside of the housing 12 through a silicone rod 6. When the drainage catheter 4 is not connected, the sealing plug 7 seals the end of the housing 7 to prevent air from entering the human body through the stomach tube 5; and the sealing plug 7 is arranged by the silicone rod 6, so that the sealing plug 7 can be effectively arranged on the side wall of the housing 12 to prevent the sealing plug 7 from affecting the use of the stomach tube connector.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
