Description

Technical Field

[0001] The utility model relates to the technical field of intestinal obstruction catheters, in particular to an intestinal obstruction silicone tube which is easy to connect. Background Art

[0002] Intestinal obstruction is one of the common diseases in surgical acute abdomen, and its incidence rate is second only to biliary tract disease and acute appendicitis. There are many causes and types of intestinal obstruction. After the onset of the disease, it can not only cause local changes in the intestine, but also cause systemic pathological changes. Therefore, for patients with intestinal obstruction, it is necessary to decompress and drain the intestinal obstruction site in time to reduce the pressure at the obstruction site. If the symptoms of intestinal obstruction cannot be relieved in time, emergency surgery must be performed, which poses great risks to both patients and doctors, and many complications will also occur after the operation.

[0003] The current intestinal obstruction catheter balloon is a simple balloon, which tends to gradually reduce its outer diameter from the middle to both ends after inflation, so that the contact surface with the intestinal wall is small, the fixing effect and sealing effect are limited, and the effect is not good;

[0004] The existing patent (publication number: CN213789515U) discloses a novel intestinal obstruction catheter. The utility model intestinal obstruction catheter is provided with a thick wall portion on the balloon wall of the rear balloon to increase the effective area when it is fixed to the intestinal wall.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A silicone tube for intestinal obstruction that is easy to connect, comprising a silicone tube body 1, an external threaded tube 2 is arranged on the front side of the silicone tube body 1, a connecting component 3 is arranged on the front side of the external threaded tube 2, and a sealing component 4 is arranged on the rear side of the internal part of the external threaded tube 2;

[0029] The connecting component 3 includes an elastic sheet 31, which is arranged in a ring shape on the front side of the external threaded barrel 2. The front side of the elastic sheet 31 is connected to a locking block 32, and the inside of the locking block 32 is bonded with a resistance piece 33. The surface of the external threaded barrel 2 is threadedly connected to an internal threaded barrel 34, and the front side of the internal threaded barrel 34 is connected to a conical barrel 35, and the inner wall of the conical barrel 35 is in close contact with the locking block 32.

[0030] Specifically, Figure 3 , Figure 4 As shown, the resistance member 33 includes a fixed block 331, which is bonded to the inner wall of the locking block 32, and a plurality of telescopic rods 332 are arranged inside the fixed block 331, and the telescopic rods 332 extend to the outer side away from the inner wall of the fixed block 331 and are connected to a resistance plate 333, and a resistance spring 334 is sleeved on the surface of the telescopic rod 332, and the top and bottom of the resistance spring 334 are respectively connected to the resistance plate 333 and the inner wall of the fixed block 331.

[0031] In this embodiment: by providing a connecting component 3, when the silicone catheter body 1 is connected to the catheter of the negative pressure drainage device, the catheter of the negative pressure drainage device can pass through the locking block 32 and the external threaded tube 2 in sequence to enter the interior of the silicone catheter body 1, and rotate and move on the external threaded tube 2 through the internal threaded tube 34. At the same time, the tapered tube 35 on the front side of the internal threaded tube 34 will gradually squeeze the locking block 32 on the front side of the elastic sheet 31, causing the locking block 32 to shrink inward, and at the same time, the contact plate 333 is in close contact with the surface of the catheter of the negative pressure drainage device, and the elasticity of the contact spring 334 can be used to enhance the stability of the connection part.

[0032] Specifically, Figure 5 As shown, the sealing assembly 4 includes a guide ring 41 , which is arranged at the rear side of the outer threaded barrel 2 , and a sealing ring 42 is bonded to the rear side of the guide ring 41 .

[0033] Specifically, Figure 5 As shown, a sealing ring 43 is bonded to the inner wall of the sealing ring 42 , and an elastic tightening ring 44 is sleeved on the rear side of the surface of the sealing ring 42 .

[0034] Specifically, Figure 5 As shown, two equidistantly distributed elastic frames 45 are arranged on the rear side of the sealing ring 42, and the elastic frames 45 are arranged in a ring shape.

[0035] In this embodiment: through the sealing component 4, when the pipe connected to the negative pressure drainage device is inserted into the external threaded tube 2, it first passes through the guide ring 41, and the guide ring 41 positions and guides the pipe so that it can smoothly enter the area where the sealing ring 42 is located. The sealing ring 42 uses its own material properties and the action of the elastic tightening ring 44 and the sealing ring 43 to form a seal around the pipe. The sealing ring 42 can effectively prevent gas or liquid from leaking from the connecting gap, and the elastic skeleton 45 provides shape support for the sealing ring 42, so that it can maintain a stable annular structure when used for a long time and subjected to different pressures.

[0036] Specifically, Figure 1 As shown, a sealing plug 5 is provided on the front side of the conical cylinder 35, and the surface of the sealing plug 5 contacts the inner wall of the locking block 32, an elastic rod 6 is bonded to the left side of the sealing plug 5, and a ring 7 is bonded to the other side of the elastic rod 6, and the ring 7 is sleeved on the surface of the silicone catheter body 1.

[0037] In this embodiment: by setting the sealing plug 5, after completing the decompression drainage, its surface can contact the inner wall of the locking block 32 to form a front end seal, thereby preventing foreign matter from entering the interior of the silicone catheter body 1, and by setting the ring 7 and the elastic rod 6 structure, the use position of the sealing plug 5 can be limited to prevent it from being lost.

[0038] Specifically, Figure 1 As shown, a front balloon 8 and a rear balloon 9 are respectively provided on the rear side of the silicone catheter body 1 , the front balloon 8 is located on the rear side of the rear balloon 9 , and a plurality of suction holes 10 are opened in a ring shape on the rear side inside the silicone catheter body 1 .

[0039] Specifically, Figure 1 As shown, the front side of the right side of the silicone catheter body 1 is connected to two injection valves 11 used in conjunction with the front balloon 8 and the rear balloon 9 respectively, and the front side of the right side of the silicone catheter body 1 is connected to an air replenishment valve 12.

[0040] In this embodiment: the design of the front balloon 8, the rear balloon 9 and the suction hole 10 on the inner rear side facilitates the precise positioning of the silicone catheter body 1 in the intestine. By injecting air into the balloon, the catheter can be fixed at a specific position in the intestine to prevent it from shifting, ensuring that the suction hole 10 can be accurately located near the obstruction site, thereby achieving efficient decompression drainage. The provision of the air replenishment valve 12 and the air injection valve 11 enables independent control of the gas volume of the front balloon 8 and the rear balloon 9, allowing the silicone catheter body 1 to better meet the needs of different patients.

[0041] Working principle: When the silicone catheter body 1 is connected to the catheter of the negative pressure drainage device, the catheter of the negative pressure drainage device passes through the locking block 32, the external threaded tube 2 and the sealing assembly 4 in sequence to enter the interior of the silicone catheter body 1, and rotates and moves on the external threaded tube 2 through the internal threaded tube 34. At the same time, the tapered tube 35 on the front side of the internal threaded tube 34 will gradually squeeze the locking block 32 on the front side of the elastic sheet 31, so that the locking block 32 shrinks inward, and at the same time, the resistance plate 333 is in close contact with the catheter surface of the negative pressure drainage device, and the elasticity of the resistance spring 334 can be used to enhance the stability of the connection part, and the sealing ring 42 itself. The material characteristics and the elastic tightening ring and the sealing ring 43 are used to form a seal around the catheter of the negative pressure drainage device. The sealing ring 42 can effectively prevent gas or liquid from leaking from the connection gap, and finally the intestinal fluid is discharged through the suction hole 10.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
