Description

An ostomy tube for infusion

technical field

The utility model belongs to the technical field of medical instruments and relates to a fistula tube which is convenient for transfusion.

Background technique

For patients who cannot eat by mouth, the current practice is to supply fluids such as liquid nutrition through ostomy tubes. The tube part of the ostomy tube is inserted into the fistula formed in the patient's abdominal wall to provide nutrition to the patient.

The technical solution adopted by the utility model is, a fistula tube for transfusion, including a tube body for implanting in the patient's body, the tube body is connected to the inlet port of the three-way valve, and the second outlet port of the three-way valve It is used to connect the nutrition tube. The first outlet end of the three-way valve is used to connect the hose of the infusion set. The three-way valve is equipped with a valve for changing the flow direction of the medium. The valve is connected with a handle for controlling the position of the valve. The three-way valve is connected with the A needle nipple is provided at one end connected with the flexible tube of the infusion set, and the needle nipple and the flexible tube of the infusion set are in an interference fit.

The utility model is also characterized in that,

The valve includes a baffle for blocking the second outlet or the first outlet, the baffle is connected with a bracket and forms a T-shaped structure, and the bracket extends to the outer wall of the three-way valve and is connected with the handle.

The pipe body and the three-way valve are threaded.

The needle nipple is covered with a protective cap.

The outlet end of the nutrition tube and the three-way valve is an interference fit.

The beneficial effects of the utility model are:

1. The tube body of the ostomy tube is connected with two outlets through a three-way valve, one is used to connect the infusion set, and the other is used to connect the nutrition tube, which is convenient for medical staff to choose the appropriate outlet according to their needs;

2. Set up a needle nipple specially used to connect the infusion set hose. The diameter of the needle nipple is designed to match the size of the infusion set hose, so that it will not leak when the patient is given 24-hour enteral nutrition;

3. There is a valve on the three-way valve, which makes the reversing operation of the fistula tube simple and safe.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model provides an ostomy tube which is convenient for infusion, as shown in Fig. 1, which includes a ostomy tube body 1 for implanting in a patient. The second outlet port is used for connecting the nutrition tube, and the first outlet port of the three-way valve 2 is used for connecting the hose of the infusion set. Wherein, the pipe body 1 and the three-way valve 2 are threaded.

The tube body 1 of the ostomy tube is connected with two outlet ports through the three-way valve 2, one is used for connecting the infusion set, and the other is used for connecting the nutrition tube, and the medical personnel can select a suitable outlet port for use according to specific needs. At the same time, the pipe body 1 and the three-way valve 2 are threaded, so that the connection between the two is firmer.

The end of the three-way valve 2 connected with the infusion set hose is provided with a needle nipple 5, and the needle nipple 5 is an interference fit with the infusion set hose. The needle nipple 5 is covered with a protective cap 6 outside.

If you need to use an infusion set hose to infuse a patient with a fistula, you only need to connect the infusion set hose to the needle nipple 5. 5 is an interference fit with the infusion set hose, so that the needle nipple 5 is reliably connected with the infusion set hose, which solves the problem that the existing fistula tube cannot be well matched with the infusion set. After the infusion is finished, the protective cap 6 is set on the outside of the needle nipple 5 to ensure that it is in a sterile state.

The three-way valve 2 is provided with a valve 3 for changing the flow direction of the medium. The valve 3 is connected with a handle 4 for controlling the position of the valve 3. The valve 3 includes a baffle 32 for blocking the second outlet or the first outlet. The baffle 32 is connected with a bracket 31 and forms a T-shaped structure, and the bracket 31 extends to the outer wall of the three-way valve 2 and is connected with the handle 4 .

During operation, the selection of the medium flow channel is realized through the valve 3 . Referring to FIG. 1 , when infusion is required for a patient, only the baffle 32 needs to be rotated to block the second outlet end for connecting the nutrition tube, so that the inlet end and the first outlet end form a passage, and the patient can be infused with fluid.

Referring to Fig. 2, when it is necessary to infuse nutrient solution for the patient, it is only necessary to rotate the baffle plate 32 to the position of blocking the first outlet end for connecting the hose of the infusion set, so that the inlet end and the second outlet end form a passage, and the The patient is infused with nutrient solution. The position of the valve 3 is controlled by the handle 4, so that the reversing action is simple, the structure is simple, the operation is convenient for medical staff, and it is suitable for popularization in clinical applications.
