Description

A disposable composite connecting tube

technical field

The utility model relates to a medical appliance, in particular to a disposable composite connecting tube.

Background technique

Intravenous infusion is a treatment method that directly injects a large amount of sterile solution or medicine into the vein. It is an important treatment measure clinically used to correct the imbalance of water, electrolyte and acid-base balance of the human body, restore the stability of the internal environment and maintain the normal physiological functions of the body. In clinical nursing work, especially when a large amount of liquid is infused, it is often necessary to connect several bottles of liquid in series with an infusion tube to infuse the patient.

At present, commonly used infusion tubes are usually made of PVC. Since PVC needs to add a certain amount of plasticizer (such as DEHP) to improve its performance during the molding process, when the infusion tube is in contact with the liquid for a long time, it is very difficult to There may be a small amount of plasticizer dissolved in the liquid medicine, causing invisible harm to the patient during the infusion. In addition, the design of the existing infusion connection tubes is often relatively single, which cannot meet different infusion needs.

Contents of the invention

Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a disposable composite connecting tube which can meet different transfusion demands, has good safety and low production cost.

The technical solution adopted by the utility model to solve the technical problem is: a composite connecting pipe for one-time use, the composite connecting pipe mainly includes a protective cap, a connecting pipe seat, a composite conduit, a connecting pipe joint and a sheath, and the protective cap The cap is arranged on the front end of the connecting pipe seat, the connecting pipe joint is arranged on the rear end of the connecting pipe seat, and the rear end of the connecting pipe joint is provided with a sheath; the above-mentioned protective cap, connecting pipe seat, connecting Both the pipe joint and the sheath are connected through a composite conduit; the outer layer of the composite conduit is made of polyvinyl chloride material, and the inner layer of the composite conduit is made of polyurethane material.

Further, a three-way joint is also provided between the connecting pipe joint and the connecting pipe seat, one end of the three-way joint is connected to the connecting pipe seat through a composite conduit, and the other end of the three-way joint is connected to the connecting pipe seat through a composite pipe. The conduit is connected with the connecting pipe joint.

As an alternative to the above technical solution, the connecting pipe joint and the sheath are replaced by a T-shaped joint, and one port of the T-shaped joint is connected to the connecting pipe seat through a composite conduit.

The above-mentioned composite conduits with a composite layer structure are all extruded at one time.

The beneficial effects of the utility model are: compared with the prior art, the disposable composite connecting pipe provided by the utility model has the following advantages:

(1) Connecting pipe joints, three-way joints or T-shaped joints can be used in the composite connecting pipe, which can meet the infusion of different medical needs;

(2) The core component composite catheter is made of PVC material on the outer layer and polyurethane material on the inner layer. The material in the composite catheter in contact with the liquid is polyurethane (excluding DEHP), which fully guarantees the safety of the patient's infusion. The inner layer of the machine is made of polyurethane material, which also reduces the production cost of the enterprise;

(3) The core component composite catheter is formed by one-time extrusion without obvious delamination.
