Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

According to the present application, there is provided a peripherally inserted central catheter with thermometry, which is substantially as described with reference to fig. 1A, 1B, 2A, 2B, 3A and 3B, and which comprises: a main conduit 1, an extension conduit 2, a temperature measuring conduit 3 and a connecting joint 4.

The main duct 1 is located on one side of the connector 4, and the extension duct 2 and the temperature measuring duct 3 are located on the other side of the connector 4, that is, the main duct 1 is connected with the extension duct 2 and the temperature measuring duct 3 through the connector 4. Specifically, main duct 1 includes infusion chamber 11 and temperature measurement chamber 12, and wherein infusion chamber 11 corresponds with the quantity of extension pipe 2, and infusion chamber is connected with extension pipe one-to-one. Referring to fig. 1 to 3, embodiments including one epitaxial conduit and one temperature measurement chamber, two epitaxial conduits and two temperature measurement chambers, three epitaxial conduits and three temperature measurement chambers, respectively, are shown, but the present application is not limited thereto and may have other numbers of epitaxial conduits and temperature measurement chambers. In the embodiment of the present application, the infusion cavity 11 and the temperature measuring cavity 12 are separated from each other and do not interfere with each other, wherein the temperature measuring cavity 12 may be disposed in the wall of the main conduit or integrated with the wall of the main conduit.

The near end of the extension catheter 2 comprises a luer connector 5 which can be externally connected to infusion bags filled with different liquid medicines, so that the simultaneous infusion of various liquid medicines with different components is realized. The extension pipe 2 is also provided with a liquid stopping clamp 7 which can block the liquid in the pipe from flowing.

The proximal end of the thermometric catheter 3 comprises a thermometric interface 8, and the thermometric interface 8 is used for connecting external equipment (such as a monitor).

In the present application, the peripherally inserted central catheter comprises an infusion channel and a thermometry channel. The infusion channel is defined by the extension duct 2 and the infusion cavity 11 of the main duct 1, i.e. the infusion channel starts from the extension duct 2 and extends to the infusion cavity 11 of the main duct 1 after passing through the connection joint 4. Wherein, the number of the transfusion channels can be one, two, three or more.
