Embodiment 1

[0017] Such as figure 1 It can be seen that the auxiliary test device for catheterization of continuous renal replacement therapy in this embodiment includes a host 1, on which a non-invasive delivery pump 2 is arranged, and also includes an inlet pipeline A and an outlet pipeline A connected to each other through the non-invasive delivery pump 2. A liquid pipeline B, the liquid inlet pipeline A is provided with a pressure sensor A3, and the liquid outlet pipeline B is provided with a pressure sensor B4; the host 1 is provided with a controller 10 and a display module 11, and the pressure sensor A3 . The pressure sensor B4 is connected to the controller 10 ; a switch 5 is also included, and the switch 5 is electrically connected to the non-invasive delivery pump 2 .

[0018] The free ends of the liquid inlet pipe A and the liquid outlet pipe B are connected with a tee, which facilitates switching and communication between the prefilling pipe, the hemodialysis pipe, and the hum...

Embodiment 2

[0030] Based on the first embodiment, this embodiment further improves the degree of automation and quantification.

[0031] Such as figure 1 , figure 2 It can be seen that the auxiliary test device for catheterization of continuous renal replacement therapy in this embodiment includes a host 1, on which a non-invasive delivery pump 2 is arranged, and also includes an inlet pipeline A and an outlet pipeline A connected to each other through the non-invasive delivery pump 2. A liquid pipeline B, the liquid inlet pipeline A is provided with a pressure sensor A3, and the liquid outlet pipeline B is provided with a pressure sensor B4;

[0032] It also includes a control system, which includes: a controller 10, used to coordinate the operation of each module; an execution module 12, used to issue instructions to the non-invasive delivery pump 2; a judging module 13, used to judge the pressure sensor A3, pressure sensor B4 Whether the feedback index meets the set threshold range;...

Embodiment 1

[0043] Compared with Embodiment 1, the advantages of this embodiment are:

[0044] A. The automation design of the control system is refined, and the work efficiency is improved; B. The judgment module 13 is added, which automatically compares the measured indicators of the pressure sensor A3 and pressure sensor B4 with the preset threshold, and the difficulty of judgment by the operator is reduced, which is convenient for the operator. Promotional use of equipment.

Abstract

The invention discloses a continuous renal replacement therapy catheterization auxiliary testing device, which is characterized in that a non-invasive delivery pump is arranged on a host, the auxiliary testing device further comprises a liquid inlet pipeline and a liquid outlet pipeline which are communicated with each other through the non-invasive delivery pump, a pressure sensor A is arranged on the liquid inlet pipeline, and a pressure sensor B is arranged on the liquid outlet pipeline; the host is provided with a controller and a display module, and the pressure sensor A and the pressure sensor B are connected with the controller; and a switch is also provided, which is electrically connected with the non-invasive delivery pump. The free ends of the liquid inlet pipeline and the liquid outlet pipeline are connected with tee joints. The method can be used for objectively and accurately judging the smooth catheterization condition of the hemodialysis double-cavity tube, and is safe and reliable to operate.

Description

technical field [0001] The invention relates to medical clinical equipment, in particular to an auxiliary device for catheterization. Background technique [0002] Continuous renal replacement therapy, commonly known as "artificial kidney", is a treatment method in which blood and dialysate are placed on both sides of a synthetic semi-permeable membrane, and the respective concentrations and osmotic pressures are used to diffuse and infiltrate each other. Continuous renal replacement therapy can excrete excess water and metabolic waste from the patient's body, and absorb electrolytes and bases that the body lacks from the dialysate, so as to achieve the purpose of correcting water, electrolyte and acid-base balance. [0003] Before continuous renal replacement therapy is implemented, doctors need to place hemodialysis dual-lumen catheters in the patient's femoral vein or internal jugular vein to create an extracorporeal circulation circuit. The patency of the catheter direct...
