Description

Technical Field

[0001] The utility model relates to a technical field, in particular to a flushing integrated device for T-tube cholangiography. Background Art

[0002] In biliary surgery, for diseases such as bile duct stones, bile duct tumors, and biliary ascariasis, a T-tube usually needs to be indwelled during the operation, and cholangiography or flushing through the T-tube is required after the operation to further clarify whether there are residual stones and to flush the biliary tract to treat biliary tract infections and prevent recurrence of stones. In addition, the T-tube is generally placed for a long time, and it is inevitable that bile turbidity will occur due to residual bile duct stones, exogenous infections, etc., resulting in secondary biliary tract infections in patients, and the biliary tract needs to be repeatedly flushed. At present, the T-tube cholangiography methods are mostly direct injection method or drip infusion method, and the T-tube flushing methods are mostly direct injection method or double-lumen T-tube biliary flushing.

[0003] The direct injection method is to directly connect a syringe to the T-tube. Since there are many types of T-tubes, the current T-tube models are 12, 14, 16, 18, 20, 22, 24, 26Fr, among which 14 and 16Fr are commonly used T-tubes for children, and the rest are for adults. The connection is not matched, which is easy to cause contrast agent spillage and prone to biliary tract infection. And because of the unmatched connection, flushing cannot be achieved either.

[0004] The drip infusion method is to insert an infusion needle into the T-tube hose, then fix the needle to the T-tube, clamp the distal end of the T-tube, and drip the contrast agent into the T-tube in the way of intravenous infusion. Generally, it is required to drip at full speed, and of course, the dripping speed can also be adjusted according to the specific situation. This method is relatively complex in operation, and the gas in the T-tube is not easy to be completely discharged, which affects the result judgment. In addition, during the cholangiography process, the patient's posture and the angle of the cholangiography bed may be adjusted as needed. At this time, the needle is easy to fall off, and during the drip infusion process, if the biliary tract pressure is high, the contrast agent may not enter the biliary tract smoothly, or the emptying of the lower end of the bile duct is faster than the drip infusion speed, resulting in incomplete biliary tract imaging and affecting the cholangiography effect. For patients with biliary tract infections, the drip infusion method cannot achieve T-tube flushing.

[0005] The double-lumen T-tube is composed of an inner tube placed in the intrahepatic bile duct and an outer tube placed in the extrahepatic bile duct. The liquid is injected through the inner tube, and after flushing the biliary tract, it is discharged out of the body through the outer tube. This method is an improvement on the ordinary T-tube and requires intraoperative placement, which is difficult to some extent. In addition, the ordinary T-tube supporting the double-lumen T-tube cannot be too thin, and generally a T-tube of Fr 22-24 is selected, and it cannot be placed in a relatively thin biliary tract. Secondly, during the flushing of the biliary tract, the drainage situation of the outer tube needs to be closely observed, and the outer tube is very easy to be blocked. Once blocked, it will affect the use effect. Summary of the Utility Model

[0006] In view of the above defects or deficiencies in the prior art, it is desirable to provide a flushing integrated device for T-tube cholangiography.

It is characterized in that: a transparent hose is connected to another port of the three-way joint, a conical joint is connected to the transparent hose, and different models of the T-shaped hoses are connected to the conical joint;

[0008] A number of equally spaced outer rings are provided on the conical joint. A conical inclined surface is provided in the hollow pipe of the conical joint, and a filter cover is covered on the conical inclined surface through a buckle.

[0009] In the present utility model, a rotatable integrated switch screw head is provided on the three-way joint.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] like Figure 1 Figure 2 As shown, a T-tube radiography flushing integrated device is according to Figure 1 To assemble this product, connect the syringe 3, the drainage hose 5 and the transparent hose 6 to the tee 2 in sequence, then connect the drainage bag 4 to the drainage hose 5, connect the conical joint 7 to the transparent hose 6, and then put different types of T-shaped hoses 1 on the conical joint 7 as needed, thereby overcoming the problem of mismatched connections, which easily causes the contrast agent to overflow. In order to prevent overflow and loose connections, an outer cover 12 and an outer ring 8 are also provided on the conical joint 7. When the T-shaped hose 1 is put on the conical joint 7, the outer ring 8 will expand the T-shaped hose 1, and the inner ring 13 on the outer cover 12 will also clamp the T-shaped hose 1 downward. Since the outer ring 8 and the inner ring 13 are misaligned, the T-shaped hose 1 is relatively convenient to access when the T-shaped hose 1 is tightened. Generally, sealed access can be achieved without the outer cover 12. If Figure 2 As shown, a filter cover 10 is provided in the conical joint 7, which mainly plays a filtering role on the circulating liquid, and the conical slope 9 and the slope limit block 11 are mainly used to clamp the filter cover 10. The filter cover 10 is made of medical materials, and its sieve holes can be selected as needed. A groove adapted to the slope limit block 11 is provided on the filter cover 10. After the filter cover 10 is placed, it is rotated again to stagger the groove and the slope limit block 11.

[0021] The procedure of T-tube angiography is as follows:

[0022] 1. The patient lies flat on the examination bed and keeps still. The doctor adjusts the channels (3, 1) in the three-way pipe 2 to be connected. The channel leading to the drainage bag 4 needs to be closed, and the T-shaped hose 1 is sterilized under aseptic operation.

[0023] 2. The operating physician draws 20 mL of 60% diatrizoate or iohexol and 20 mL of 0.9% saline into a 50 mL sterile syringe 3, and uses the syringe 3 to withdraw bile and gas from the T-shaped hose 1 and the bile duct.

[0024] 3. Under X-ray fluoroscopy, slowly inject the contrast agent into the patient's T-shaped hose 1, observe the filling condition of the biliary tract, and take a film when the imaging is satisfactory.

[0025] 4. After the imaging is completed, the operating physician uses the syringe 3 to aspirate the contrast agent and withdraw the syringe 3. Connect the T-shaped hose 1 to the drainage bag 4, and the patient should not move violently.

[0026] Process of T-tube irrigation:

[0027] 1. The patient lies flat on the hospital bed. A 20-ml sterile syringe 3 aspirates about 10 ml of normal saline. The operating physician adjusts the channels of the three-way stopcock 2 to be connected (channel 3, 1).

[0028] 2. Inject the saline in the sterile syringe 3 into the T-tube through the three-way stopcock, and then adjust the three-way stopcock 2 to be connected (channel 2, 1) to make the turbid bile and normal saline in the T-shaped hose flow into the drainage bag 4.

[0029] 3. Repeat the operations in step 1 and step 2 multiple times until the outflow liquid is basically clear. Observe and ask the patient if there are any discomforts such as abdominal pain, abdominal distension, fever, etc. during the irrigation process. After the irrigation is completed, connect the T-shaped hose 1 to the drainage bag 4.
