Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an emergency such as a fire and an earthquake and equipment trouble during treatment of extracorporeal fluid circulation such as hemodialysis and plasma exchange.
(EN) Provided is a detachable extracorporeal circulation circuit that enables reattachment to a patient when the patient's individual circumstances arise and the treatment is temporarily interrupted.

[Prior Art and Problems of Prior Art] In the treatment of extracorporeal fluid circulation such as hemodialysis and plasma exchange, the patient's blood vessel is punctured with an elastor needle, and the fluid is introduced into the extracorporeal circulation circuit and the fluid treatment device. Is going.

During such treatment, natural disasters, equipment troubles, and individual patient circumstances may occur, forcing the treatment to be interrupted.

For example, in the event of a natural disaster, it is an emergency, so the extracorporeal circulation circuit is cut to prevent the body fluid of the patient from leaking to the outside, but various medical devices must be prepared. In addition, there is a problem that it is impossible to reconnect and perform extracorporeal circulation.

Also, in the event of equipment problems and individual patient circumstances, with the elastor needle punctured in the patient, remove the elastor needle and the extracorporeal circulation circuit, connect the elastor needle to the syringe containing the anticoagulant, and then The patient had left the vessel. Also in this case, the operation was troublesome. Therefore, the present inventor has made intensive studies in order to solve the above problems, and as a result, arrived at the next inventor.

[Means for Solving the Problems] The present invention comprises an arterial circuit 2 and a venous circuit 3,
A male member 12a and a female member 1 are provided in the middle of the arterial circuit 2.
A connector 6 composed of 3a is arranged, and the connector 6
Stoppers 8 and 9 are attached to the front and rear of the connector, a connector 7 including a male member 13b and a female member 12b is arranged in the middle of the vein side circuit 3, and stoppers 10 and 11 are attached to the front and rear of the connector 7, 6 and the connector 7, the male member 12a (12b) and the female member 13a (13b), and the male member 12a and the female member 13
(EN) A detachable extracorporeal circulation circuit capable of mutually disconnecting and reconnecting a male member 12b and a female member 13a.

[Embodiment] FIG. 1 is a schematic view of a detachable extracorporeal circulation circuit 1, and FIG. 2 is a partially enlarged view of FIG.

The detachable extracorporeal circulation circuit 1 includes a vein side circuit 2 and a vein side circuit 3.
It consists of

A branch line 21, a rolling tube 22, and a drip chamber 23 are arranged in the middle of the arterial circuit 2, and a drip chamber 24 is arranged in the middle of the vein circuit 3.

The connectors 6 and 7 are arranged at positions of 20 to 100 cm from the shunt connectors 4 and 5 attached to the tips of the circuits 2 and 3, respectively.

The arrangement positions of the connectors 6 and 7 are not necessarily limited to the above range, and the connectors 6 and 7 can be attached anywhere as long as they can be detached and reattached quickly and easily.

Further, stoppers 8 and 9 are arranged before and after the connector 6, and stoppers 10 and 11 are arranged before and after the connector 7.

As shown in FIG. 2, the connector 6 is composed of a male member 12a and a female member 13a, the connector 7 is composed of a male member 12b and a female member 13b, and the male member 12a (12b) and the female member 13a (13b) are removable with one touch. Is formed in.

The male member 12a (12b) and the female member 13a (1
The inner diameter of the bodily fluid flow passage 3b) is formed to be substantially the same as the inner diameters of the artery side circuit 2 and the vein side circuit 3. This makes it possible to smooth the flow of body fluid, prevent turbulence, and prevent blood coagulation.

Next, an example of the method of use of the present invention when the above-mentioned emergency occurs during the extracorporeal circulation treatment will be described with reference to FIG.

The stoppers 8, 9, 10, 11 are clamped to completely cut off the body fluid passages of the vein side circuit 2 and the vein side circuit 3. Next, the connector 6 is separated into the male member 12a and the female member 13a, and the connector 7 is separated into the male member 12b and the female member 13a.
Separate into b. Then, the male member 12a and the female member 13
b, the male member 12b and the female member 13a are fitted together, the clamps of the stoppers 8, 9, 10, 11 are released to circulate body fluid. In the closed circuit 15 on the patient side, the body fluid circulates due to the arterial pressure, and in the closed circuit 16 on the body fluid treatment device 12 side, the body fluid is circulated by the body fluid pump to prevent the coagulation of the body fluid.

When restarting the extracorporeal circulation, the stoppers 8, 9, 10,
11, the male member 12a and the female member 13b,
The male member 12b and the female member 13a are removed, and the male member 12a and the female member 13a, and the male member 12b and the female member 1
It can be restarted by fitting 3b again.

In the invention of the present application, the mounting position of the connector, the shape, the structure, and the type of the clamp, the connector, etc. are not limited to those shown in the drawings, but may be any as long as the objects and effects of the invention of the present application can be achieved. It can be changed accordingly.

[Effects of the Invention] As described above, according to the present invention, when the circulation of the body fluid is temporarily interrupted, the male member 12a, the female member 13b, and the male member 1 forming the connectors 6 and 7 are provided.
2b and the female member 13a are fitted, and closed circuits 15 and 16 are formed on the patient side and the body fluid treatment device 12 side, respectively, so that circulation of body fluid can be continued. To resume the extracorporeal circulation, the male member 12a and the female member 13 constituting the connectors 6 and 7 are restarted.
a, the male member 12b and the female member 13b can be fitted again.

Even if the extracorporeal circulation is forced to be interrupted, the device and the patient can be detached and reattached safely without being solidified with body fluid.

The drip set can be connected cleanly even after the drip injection after the treatment.

It is an excellent device that has the effects of the above.
