Description

Safe continuous temperature measurement type femoral vein double-cavity hemofilter tube

Technical Field

The utility model relates to the technical field of medical treatment, in particular to safe type femoral vein two-chamber blood filter tube that lasts the thermometric.

Background

Continuous Renal Replacement Therapy (CRRT) is a continuous, slow-clearing treatment of water and solutes, and belongs to blood purification therapy. In recent years, the CRRT technology is mature day by day, the clinical application range of the CRRT technology far exceeds the field of kidney treatment, and the CRRT technology is expanded to the treatment and rescue of various clinical common critical patients. The premise of stable operation of CRRT treatment is that a reasonable deep venous catheter is kept, the femoral vein catheterization is frequently used as a main part of the CRRT catheterization because technical requirements are low and fatal complications are few, however, the femoral vein is limited in movement of a patient due to the particularity of the anatomical position of the femoral vein and is not easy to effectively fix, so that the related blood flow infection and related complications of the catheter are obviously increased, and whether the fixing mode is reasonable or not directly determines the unobstructed condition of the venous catheterization, and the normal proceeding and treatment effects of CRRT treatment can be influenced. The reasonable fixing mode can not only reduce the unplanned tube drawing of the catheter, but also reduce the difficulty of nurses in the maintenance of the femoral vein double-cavity hemofilter. In addition, extracorporeal circulation and large fluid exchange in CRRT therapy can lead to heat loss, produce a cooling effect, and cause the body temperature of a patient to drop. Hypothermia can cause cold tremor, reduce oxygen supply of body tissues, influence blood coagulation function, cause adverse effect to patients, and increase treatment and nursing difficulty. In the prior art, the femoral vein double-cavity blood filter tube is fixed on the skin through an airplane head and a suture, the double-cavity blood filter tube is easy to rotate and adhere to the wall when in use, so that blood guiding is not smooth, and in addition, a patient uses the thermometer Q4H to measure the body temperature conventionally during CRRT treatment, so that continuous body temperature monitoring and body temperature management are difficult to carry out.

The utility model discloses the during operation is responsible for Y type pipe and inserts trapezoidal mounting after most advanced and put into femoral vein, and the blood adjustment of evacuation blood vessel and return blood vessel is responsible for the angle, will be responsible for when adjusting to the optimum position protruding grafting advance fixed recess on and fix to through the suture through fixed orifices seam on skin, three temperature sensor on the Y type pipe can connect external guardianship equipment in addition and carry out lasting physical body temperature control and body temperature management, in time alarm handling when the body temperature appears unusually.

The utility model adopts the above technical scheme to compare with prior art, beneficial effect: the equal-dividing fixing grooves on the trapezoidal fixing piece are mutually inserted with the bulges on the main pipe of the catheter, so that the catheter is fixed at the optimal position, the CRRT treatment is ensured to be normally carried out, and the pipeline is not easy to slip; in addition, continuous body temperature monitoring and body temperature management are carried out through three temperature sensors on the Y-shaped catheter, so that abnormal body temperature can be found in time, effective nursing measures can be taken, and complications can be reduced.

In order to play a role in fixing when contacting with the skin and reduce pressure injury, a cotton pad body is arranged on one surface of the trapezoidal fixing piece contacting with the skin.

In order to ensure that the Y-shaped catheter finds the optimal position, ensure smooth blood guiding and prevent wall adhesion when the catheter is used, 24 equally-divided fixing grooves are arranged on the inner periphery of the circular through hole in the trapezoidal fixing piece.

In order to prevent the blood from flowing back when the catheter is not used, the tail end of the blood leading tube and the tail end of the blood returning tube are both provided with a single-hand clamp, and the single-hand clamp can be clamped and connected with a heparin cap to close the catheter when the catheter is not used.

Further, the temperature sensor has a size of 2 mm.

Furthermore, the specification of the Y-shaped catheter is 11.5Fr-20cm of a double cavity.
