Technical Field

The utility model relates to a central venous catheter with temperature detection function.

Background

The central venous catheter belongs to one of intravascular tubes, can be used for measuring the central venous pressure of a human body, is used for evaluating the function of a blood circulation system of the human body, and is one of main indexes for clinical observation of hemodynamics; an extracorporeal infusion channel can also be established for drug injection or large and rapid intravenous infusion to a patient. The central venous catheter is an important channel for monitoring, fluid infusion and blood transfusion and inputting various rescue medicaments in and after operations of severe patients. Intensive Care Unit (ICU) inpatients inevitably suffer from peripheral repeated venipuncture due to the need of long-term infusion, blood product infusion, intravenous nutrition treatment and the like, and in addition, the damage to blood vessels caused by drugs, hypertonic liquid and the like causes difficulty in peripheral vascular puncture, and at the moment, a central venous catheter is a better choice. The patient is infused by inserting the central venous catheter into a patient's vein, such as the subclavian vein, by a puncture technique.

Chinese patent 201820123917.4 discloses a central venous catheter, which comprises a fixing pad, an outer tube body, a clip and a joint; the outer pipe body is connected between the fixing pad and the joint; the clamp is arranged on the outer tube body, and the outer tube body is transparent; the outer pipe body is further sleeved with a telescopic corrugated pipe; the first end of the corrugated pipe is connected to the fixing cushion, and the second end of the corrugated pipe is connected to the joint, so that the corrugated pipe can completely cover the outer pipe body; at least one of the connection between the first end of the corrugated pipe and the fixing pad and the connection between the second end of the corrugated pipe and the joint is detachably connected, so that at least one end of the corrugated pipe can be disconnected, and the outer pipe body is exposed after the corrugated pipe is contracted; the clamp is positioned in the middle of the corrugated pipe and used for conducting or blocking the outer conduit; the corrugated pipe is made of a light-shielding material.

The above method has the defects that the body temperature of the patient cannot be monitored simultaneously during transfusion, and doctors cannot make more accurate diagnosis according to the temperature change in the patient body and adjust treatment measures in time.

Therefore, how to provide a central venous catheter with a sealing function, convenient manual operation and light temperature detection function becomes a problem to be solved in the industry.
