CN205360128U - Take transfer line of connector - Google Patents

Abstract

The utility model discloses a take transfer line of connector is equipped with the connector on this transfer line, the connector includes the ring that two interconnect are in the same place, the transfer line passes the two rings circle in proper order to make the transfer line form double -H groove weld shape structure. Can make the transfer line form two " U " shape structure through the connector before the infusion, liquid medicine when the medicine bottle in uses up and when in time not changing the medicine bottle because " U " shape department produces the siphonage, can prevent that blood from flowing backwards and the air can not to get into the patient internal. Infuse when finishing, can take off the connector, get rid of two " U " shape structure of transfer line for it is internal that " U " liquid medicine in the shape can continue class to advance the patient, avoids the liquid medicine to waste.

Description

An infusion tube with a connector

technical field

The utility model relates to a transfusion tube, in particular to a transfusion tube with a connector for preventing blood backflow.

Background technique

People will inevitably get sick in life, and some people need drips when they are sick, and need to frequently observe the remaining amount of liquid medicine in the infusion bottle during infusion. Pulling out will cause blood to flow back. Although there are technologies to solve the problem of blood backflow, such as the siphon infusion set with Chinese patent application number 201220715105.1, this utility model adds a section of U-shaped tube to the infusion tube, and uses the siphon principle to prevent air from entering the human body and prevent blood backflow , but the infusion set has the following disadvantages: 1, the infusion tube must be transformed, that is, a section of U-shaped pipe is set, and the infusion tube of the original structure cannot be utilized, which is inconvenient to use. 2. It will cause the medicinal liquid in the U-shaped tube to fail to flow into the human body and cause waste.

Utility model content

The technical problem to be solved by the utility model is to provide an infusion tube with a connector which can prevent the blood from flowing backwards by using the existing structure infusion tube.

For solving the problems of the technologies described above, the technical solution of the utility model is:

An infusion tube with a connector, the infusion tube is provided with a connector; the connector includes two interconnected rings, and the infusion tube passes through the two rings in turn, so that the infusion tube forms Double U-shaped structure.

Preferably, an opening is provided on one of the rings of the connector.

Preferably, openings are provided on both rings of the connector.

Preferably, the connector is further provided with a third loop, and the third loop is connected to one of the first two loops.

Preferably, the third ring is provided with an opening.

After adopting the above scheme, the utility model has the following advantages:

1. Because a connector is provided, the infusion tube can be inserted into the two rings of the connector before use, so that the infusion tube forms a double U-shaped structure, and a siphon phenomenon can be formed after the liquid medicine in the infusion bottle flows out to prevent blood Backflow and air entering the body;

2. When the infusion is completed, remove the connector and remove the double "U"-shaped structure of the infusion tube, so that the liquid medicine in the "U" shape can flow into the human body and avoid waste of liquid medicine;

3. Without changing the structure of the original infusion tube, a double U-shaped structure can be formed on the infusion tube by using one connector, so as to prevent blood from flowing backward and be more convenient to use.

Fig. 2 is a structural diagram of the connector described in the utility model;

Fig. 3 is a schematic diagram of another structural connector of the present invention.

detailed description

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

The utility model discloses an infusion tube with a connector, as shown in Fig. 1 and Fig. 2, which is a preferred embodiment of the utility model, and the infusion tube 1 is provided with a connector 2. in:

The connector 2 includes two interconnected rings 21 , and the infusion tube 1 passes through the two rings 21 sequentially, so that the infusion tube 1 forms a double U-shaped structure 11 .

During infusion, the medicinal liquid will be stored in the double "U"-shaped part formed on the infusion tube 1, and then flow to the patient's vein after storing a certain amount. When the liquid medicine in the liquid bottle runs out and is not replaced in time, the liquid medicine in the infusion tube will not continue to flow to the patient's vein due to the siphon phenomenon in the "U"-shaped part, preventing the patient's blood from flowing back and air from entering. When the infusion is about to end, the connector 2 can be removed from the infusion tube 1, and the double U-shaped structure 11 can be removed, so that the medical solution in the "U" shape can continue to flow into the patient's vein, avoiding the storage of the medical solution in the "U" shape. waste in the structure.

Further, in order to facilitate the removal of the connector 2 from the infusion tube 1, an opening 22 can be provided on one of the rings 21 or two rings 21 of the connector 2, and the ring can be inserted through the opening 22 during use. 21 sets on the infusion tube 1.

In addition, in order to make the infusion set 1 form a double U-shaped structure 11 more conveniently, the connector 2 can further be provided with a third ring 23, which is connected with one of the first two rings 21. It is also possible to set an opening 22 thereon. When in use, the infusion tube 1 passes through the three loops 21 and 23 in sequence to form a double U-shaped structure 11 .

The above are only preferred embodiments of the present utility model, and are not intended to limit the technical scope of the present utility model. Therefore, any changes or modifications made according to the claims of the utility model and the specification should belong to the utility model. Within the scope covered by the utility model patent.
