Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 In the present invention, when performing priming for cleaning and disinfecting a dialyzer and an arterial circuit and a venous circuit used for artificial dialysis, the arterial chamber and the venous chamber are inserted into the left and right holders with one touch, and these chambers are moved to the left and right. The present invention relates to a reversible chamber holder which is adapted to be reversed while being attached to the holder.

[0002]

[Prior art]

 When performing artificial dialysis, in order to avoid the patient from being contaminated with bacteria, the dialyzer, arterial circuit, and venous circuit should be filled with physiological saline (hereinafter referred to as "saline water") in advance to clean and disinfect these circuits. It is necessary to carry out priming that is designed to do.

This priming will be described with reference to FIGS. 23 and 24. The illustrated dialyzer 30, arterial circuit 31, and venous circuit 32 are sterilized in advance and sold in a bag.

In use, after opening the bag, the bag is taken out, and the dialyzer 30, the arterial circuit 31, and the venous circuit 32 are connected by respective circuit tubes, and priming in which saline is filled and circulated in these circuits. I do.

However, during the priming, when the air in the arterial circuit 31 is sent into the fine tube formed by the permeable membrane in the dialyzer 30, the air closes the tube or becomes small bubbles to form the tube. By adhering to the wall surface, it blocks the permeable membrane surface, restricts the flow of dialysate, and hinders the flow of blood to significantly reduce the dialysis efficiency.

Therefore, in priming, as shown in FIG. 23, the arterial circuit 31 is not connected to the arterial side connection port 34 of the dialyzer 30, the arterial chamber 35 is turned upside down 180 °, and the air outlet is released. And the blood pump 36 is driven, and by the liquid feeding operation of the pump 36, the saline fed down from the saline saline bag 37 is conducted into the circuit tube to fill the arterial chamber 35. At this time, the air pushed out in the tube on the upstream side of the arterial chamber 35 is driven to the downstream side of the arterial chamber 35 and is discharged into the air from the connection port 38 on the downstream side of the arterial chamber 35.

After confirming that the chamber and the circuit tube have no air tank, the connection port 38 of the circuit tube of the arterial circuit 31 is connected to the arterial side connection port 34 of the dialyzer 30, and the blood pump 36 is further connected. By driving the dialyzer 30 to circulate saline in the dialyzer 30 to circulate in the tube on the upstream side of the venous circuit 32 and to push out the air therein, while filling the venous chamber 39 with saline. By this, the saline solution is circulated in the tube on the downstream side of the vein circuit 32, and the saline solution is discharged from the outlet for a predetermined time, and the dialyzer 30, the arterial circuit 32, and the entire vein circuit 32 are washed and disinfected.

Then, the arterial chamber 35 and the venous chamber 39 are turned upside down from the state of FIG. 23 to the state of FIG. 24, and the normal dialysis treatment use state is set.

[0009]

[Problems to be solved by the device]

 As described above, in the above priming, it is necessary to turn the arterial chamber 35 and the venous chamber 39 upside down so as to return to the normal dialysis treatment use state.

By the way, as shown in FIG. 24, the air in the tube on the side of the venous circuit 32 is separated into gas and liquid in the venous chamber 39 due to the drop pressure, and is discharged or discharged from the connecting port of the tubing. Air in circuit 32 does not enter the blood passages of the dialyzer. Therefore, the air in the dialyzer 30 can be removed by only inverting the arterial chamber 35 without inverting the venous chamber 39. Therefore, in order to perform such priming, the arterial chamber 35 can be used. The purpose is achieved by reversing only.

In any case, conventionally, a holder for mounting these left and right chambers 35, 39 is of a fixed type with respect to a column, and when the respective chambers 35, 39 are turned upside down, This required a troublesome operation of removing the chambers 35 and 39 from the holder, turning them upside down, and reattaching them to the holder.

The object of the present invention has been made in view of the above circumstances, and the left and right chambers are provided as a means for filling the chamber and the circuit with a cleaning and disinfecting solution for priming in the blood circuit of the dialysis machine. It provides a holder that reverses 180 ° either integrally or independently. Instead of the operator removing, reversing or attaching the chamber itself, the left and right chambers must be attached to their respective holders. By reversing this holder, the left and right chambers were integrally or independently reversed by 180 °.

[0013]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the inversion type chamber holder of the present invention, in the chamber holder in the priming circuit of the dialysis device, detachably fits the arterial chamber and the venous chamber on both left and right sides of the support column and clamps them. The left and right holders having the chamber holding portions are formed, and the holding plate is provided such that these holders are reversibly attached to the columns, or the inverted state is locked in a fixed state.

Further, guide grooves for inserting the support columns are formed in the holding plate, the holders are integrally fixed to the left and right sides of the holding plate, and the holders are guided to substantially central portions on both side surfaces of the guide grooves. In addition to forming a long hole, a long window is formed substantially in the center of the bottom side surface of the holding plate, and pins are provided so as to project from the upper end of the support column to both side portions having an extra length so as to guide the holding plate. By making the holding plate movable along the support column within the range of the guide elongated hole, the upper end of the support column moves to a position where it is exposed to the long window of the holding plate. The left and right holders of the holding plate may be reversible around the pin, or the left and right holders may be fixed by moving the holding plate downward along the support column. .

Further, the holding plate is formed to have an L-shaped cross section and provided separately on the left and right sides of the column, and a guide elongated hole is formed along substantially the center of the side surface of each holding plate. While making incision slots at both ends of the side surface of each of the sides to make one side of each incision slot short, a headed pin is projected from both ends of the post having an extra length from the upper end. By locking it in the guide elongated hole of the holding plate, the holding plate can be freely moved along the supporting column in the guide elongated hole of the holding plate, and is separated downward from the mounting position of the headed pin. The lower end pins protruding from both sides of the supporting column are inserted into the cut-out long hole of the holding plate from the short side to lock the holding plate, while holding the holding plate upward. By moving the lower end pin out of the incised long hole and reversing the holding plate, The holder fixed to each of the holding plates may be turned upside down independently of each other, or the inverted state of each holder may be fixed.

Further, tube hooks for elastically sandwiching the circuit tube may be formed at both ends of the left and right holders.
