Example Embodiment

[0016] Example one

[0017] like figure 1 Visible, continuous renal replacement therapy catheterization auxiliary test apparatus according to the present embodiment includes a host 1, the host 1 is provided on the presence or absence of record feed pump 2, further comprising a non-invasive delivery pump 2 to communicate with each other, and an inlet pipe A liquid conduit B, set at the inlet conduit A3 A pressure sensor, a pressure sensor is provided on the liquid line B B4; the controller 10 is provided with a display module 11 and the host 1, the pressure sensor A3 the pressure sensor 10 is connected to the controller B4; 5 further comprising a switch, the switch 5 and the non-invasive delivery pump 2 is electrically connected.

[0018] The inlet conduit A, the free end of the liquid line are connected to a three-way B, to make switching between the pre-charge line, dialysis tubing, catheter body end, in communication.

[0019] Work process:

[0020] A, the liquid conduit A, the ...

Example Embodiment

[0029] Example 2

[0030] On the basis of the first embodiment, this embodiment further improves the degree of automation and quantization.

[0031] like figure 1 , figure 2 Visible, continuous renal replacement therapy catheterization auxiliary test apparatus according to the present embodiment includes a host 1, the host 1 is provided on the presence or absence of record feed pump 2, further comprising a non-invasive delivery pump 2 to communicate with each other, and an inlet pipe A liquid conduit B, set at A3 with a pressure sensor on the inlet conduit A, the pressure sensor that is provided on the liquid line B4 B;

[0032] Further comprising a control system, said control system comprising: a controller 10 for coordinating the operation of each module; execution module 12, the feed pump 2 to give commands to noninvasive; determining module 13, a pressure sensor for determining A3, B4 pressure sensor feedback indicator meets the set threshold range; counting module 14 for non...

Example

[0043] Relative to Examples 1, the advantage of this embodiment is:

[0044] A, refine the automation design of the control system, improve the work efficiency; B, increase the judgment module 13, automatically compare the pressure sensor A3, the pressure sensor B4 measurement index and the preset threshold, the operator judgment is decreased, easy to Promotion 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...
