Description

Self-circulation joint of machine in CRRT patient suspension treatment

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to self-loopa of CRRT pipeline connects.

Background

Continuous Renal Replacement Therapy (CRRT) is a blood purification treatment technique that continuously and slowly removes water and solutes by extracorporeal blood purification to replace renal function. Compared with the common hemodialysis, the CRRT prolongs the blood purification treatment time and reduces the treatment efficiency in unit time, so that the influence of the solute concentration and the volume change in the blood on the organism is minimized, and a filter with high permeability and good biocompatibility is adopted; provides an extremely important homeostasis balance for the treatment of critically ill patients.

There are many machines that can perform CRRT, most of which are designed to achieve blood circulation by connecting a dual lumen blood filter tube implanted in the patient's vein, one to draw blood and one to return blood. The CRRT is very expensive, and when a severe patient needs to go out for temporary examination or an emergency operation, the patient needs to return to the room to replace the CRRT for re-use without self-circulation. Therefore, firstly, the replacement cost is too high, unnecessary loss is caused to the patient, secondly, waste of manpower and material resources is caused, and the optimal treatment time of the patient is delayed.

To address this phenomenon, a three-way valve is often used to connect the CRRT line and then externally connect liquid to simulate human body circulation, so that the machine operates normally to form self-circulation. However, this method increases the risk of pipeline contamination due to more external consumables. And if the external liquid is connected, the machine can be influenced to calculate the treatment dosage; if the external liquid is not directly connected, the machine can mistakenly think that the pipeline has no pressure and give an alarm, and a nurse needs to frequently process the alarm of the machine, so that the labor consumption is increased.

Disclosure of Invention

In order to solve the problem, the utility model discloses a self-loopa of CRRT pipeline connects, simple structure reduces the infection risk, avoids external liquid moreover, reduces unnecessary liquid and loses and calculate the error.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a self-loopa connects of CRRT pipeline, includes pipeline, side joint block, check valve, the pipeline is the hard tube, the quantity of side joint block is two both ends of fixing at the pipeline, the side joint block is ring shape and middle round hole and pipeline intercommunication, side joint block surface is equipped with the screw thread, and two side joint block colours are different, the check valve sets up in the pipeline.

As an improvement of the utility model, the pipeline is a transparent plastic pipeline.

The utility model has the advantages that:

(1) in the outgoing inspection process, the two side connecting blocks are connected with the blood leading end and the blood return end of the CRRT pipeline, the concave-convex jacks and the threads are connected, the machine forms a closed cycle, and the self-circulation of the machine in the outgoing inspection process can effectively prolong the service time of a matched pipeline; the number of connecting pipelines is reduced, and the possibility of infection is reduced;

(2) liquid is not externally connected, so that the possibility of liquid loss and calculation error is reduced;

(3) the one-way valve is additionally arranged in the hard pipeline, pressure is artificially produced, and a non-pressure alarm is sent out due to the fact that the blood flow of the machine is too smooth;

(4) the corresponding color is designed to ensure blood flow direction.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the figure, a self-loopa of CRRT pipeline connect, including pipeline 1, side joint block 2, check valve 3, pipeline 1 is the hard tube, the quantity of side joint block 2 is two and fixes the both ends at pipeline 1, side joint block 2 is ring shape and middle round hole and pipeline 1 intercommunication, 2 surfaces of side joint block are equipped with

screw thread

4, and 2 colours of two side joint blocks are different, check valve 3 sets up in pipeline 1.

The utility model discloses a self-loopa connects, both ends are the notch, in the inspection process of going out, machine 5 (adopt gold treasure flex machine, this model can carry out all CRRT treatment modes, it reaches the effect of blood circulation through being connected with the internal two-chamber blood filter tube of inserting patient during the treatment) suspends the treatment and breaks away from with patient, machine 5 draws blood end and feedback end 6 and inserts in pipeline 1 earlier, then the outside is threaded connection, through unsmooth socket + threaded connection, machine self forms a confined circulation, make its self-loopa can effectively prolong supporting pipeline live time like this in the inspection process of going out; the utility model discloses simple structure is practical, and connecting line reduces, reduces to infect and takes place probably, does not connect liquid outward moreover, reduces liquid and loses and calculate the error possibility.

The pipeline 1 of the utility model is a transparent plastic pipeline, the one-way valve 3 is installed in the hard pipeline 1, pressure is artificially produced, and the machine is prevented from sending out a no-pressure alarm due to the fact that the blood flow is too smooth; the pipeline 1 is transparent to clearly see the liquid flow direction.

Two side connect 2 colours of piece different (for example one end red one end is blue), which connects the import, which connects the export, ensures the blood flow direction in the very convenient identification.

The technical means disclosed in the present invention is not limited to the technical means disclosed in the above embodiments, but also includes the technical solution formed by combining the above technical features at will.
