At present, the connection device used to connect the jejunum nutrition bag and the jejunum nutrition tube is a disposable three-way connection for infusion, which can realize the connection between the two, and the clamping function of the jejunum nutrition tube can be realized after the nutrient solution is input. However, the disposable tee for infusion does not have an interface specially connected to the jejunal nutrition tube. When using it, medical personnel need to use tools such as hemostatic forceps to install it. Pipe pollution, the utility model just solves this problem.

Contents of the invention

In order to solve the above technical problems, the purpose of this utility model is to provide a one-time in-line three-way device, which is mainly used for the connection between the jejunum nutrition bag and the jejunum nutrition tube.

The purpose of this utility model is achieved through the following technical solutions:

A disposable in-line three-way device comprising a three-way valve, a main inlet, a side inlet and a tapered outlet;

The main inlet and the side inlet are respectively connected with a jejunum nutrition bag or a syringe;

The tapered outlet is connected with the jejunum nutrition tube;

The three-way valve is in communication with at least two of the main inlet, side inlet and tapered outlet.

Compared with the prior art, the beneficial effects of the technical solution provided by the utility model are:

The structure is simple and the operation is convenient. While completing the connection between the jejunum nutrition bag and the jejunum nutrition tube, the jejunum administration or pipeline flushing can be completed through the side inlet, which makes the operation more reasonable, convenient and hygienic, and can greatly reduce the operation difficulty of medical staff. Improving operating efficiency can also reduce the probability of patients suffering from pathological changes due to interface contamination.

Detailed ways

It is easy to understand that, according to the technical solution of the utility model, those skilled in the art can propose multiple structural modes and manufacturing methods of the utility model without changing the spirit of the utility model. Therefore, the following specific implementation methods and drawings are only specific descriptions of the technical solution of the utility model, and should not be regarded as the whole of the utility model or as a limitation or limitation of the technical solution of the utility model.

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.

Fig. 1 is a schematic diagram of a one-time in-line three-way structure, the structure includes: a three-way valve 4, a main inlet 1, a side inlet 2 and a tapered outlet 3;

The main inlet and the side inlet are respectively connected with a jejunum nutrition bag or a syringe;

The tapered outlet is connected with the jejunum nutrition tube;

The three-way valve is connected to at least two interfaces of the main inlet, side inlet and tapered outlet; according to actual needs, the three-way valve can realize any two ports of the main inlet, side inlet and tapered outlet. connection between one or three interfaces.

The tapered outlet is connected with the jejunal nutrition tube through direct insertion.

The three-way device also includes a main inlet cover 5, an outlet cover 7 and a side inlet cover 6;

The above-mentioned main inlet cover is sealingly connected with the main inlet;

The outlet cover is sealingly connected with the tapered outlet;

The above-mentioned side inlet cover is sealedly connected with the side inlet through the side inlet screw 9 provided at the side inlet.

The above-mentioned main entrance is connected with the jejunum nutrition bag to complete nutrition supply, and can be sealed with the main entrance cover when not in use.

The above-mentioned side inlet is connected with the syringe, which can complete jejunum administration or pipeline flushing, and can be sealed with a side inlet cover when not in use;

A movable device 8 is arranged at the above-mentioned main entrance, and a main inlet screw port 8a is arranged in the caliber of the movable device, through which the main inlet screw port is connected with the outlet pipe screw port of the jejunum nutrition bag.

The process of using the above-mentioned embodiment is as follows:

As shown in Figure 2, when the patient needs to be fed through the jejunal nutrition tube 17, the nursing staff will turn the three-way valve of the disposable in-line three-way to the position where the main inlet and the outlet communicate, and then turn the three-way valve of the disposable in-line three-way The outlet 3 is connected with the jejunum nutrition tube, and then the prepared jejunum nutrition bag 10 is passed through the jejunum nutrition bag outlet tube screw 14 provided at the jejunum nutrition bag outlet tube 13 and the activity provided at the main entrance of the disposable in-line three-way The device 8 is connected, and after confirming that the connection is correct, it starts to support.

When feeding is completed, the nursing staff disconnects the main entrance of the disposable in-line tee from the jejunal nutrition bag, and covers the main entrance with an entrance cover.

When jejunal administration is required, the side inlet and outlet are connected through the three-way valve, and the syringe 15 is connected to the side inlet 2 for administration. After the administration is completed, the side inlet is covered with a side inlet cover.

When pipeline flushing is required, it is carried out through the main inlet or side inlet of the disposable in-line tee. After flushing, cover the main inlet and side inlet with the inlet cover.

Although the embodiments disclosed in the present utility model are as above, the content described is only an embodiment adopted for the convenience of understanding the present utility model, and is not intended to limit the present utility model.
