Description

[Detailed description of the invention] (Field of industrial application) The present invention is a body fluid treatment device that guides body fluids such as blood and ascites to artificial organs and returns the treated body fluids back into the body. The present invention relates to a body fluid treatment device that can be operated in a sanitary manner.

(Prior art) A body fluid treatment device consists of an artificial organ containing a membrane filter and an adsorbent in a housing, and an extracorporeal circulation circuit connected to the artificial organ. Can be assembled. For example, in a plasma separation and exchange device that uses a membrane filter as an artificial organ, as shown in FIG. and connect the blood lead-out circuit B to form an extracorporeal circulation blood circuit. Further, a plasma discharge circuit C is connected to the plasma outlet through a plasma pump 3, and then a fluid replacement circuit D from a fluid replacement bag 4 is connected to a mixer 5 through the fluid replacement pump 3.

(Problems to be Solved by the Invention) In the above device, the user must connect four types of circuits without error on site, and is required to be skilled. Furthermore, in recent years, due to the emphasis on safety, artificial organs that have been sterilized by autoclaving have come into widespread use. Since such artificial organs are filled with distilled water, care must be taken to prevent the body fluids filled inside from flowing out in artificial organs in which the outlet and inlet for body fluids are arranged separately at both ends. , requires a higher level of skill.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a body fluid treatment device that can be easily and reliably assembled during use, and that can be operated hygienically.

(Means for Solving the Problems) The device of the present invention includes a male (or female) connector having a plurality of connection ports, to which an end of a tube connected to at least a body fluid inlet and an outlet is connected to an artificial organ. A female (or male) connector unit having multiple connection ports to which at least the ends of the body fluid inlet circuit and the body fluid outlet circuit are connected to the body fluid inlet and body fluid inlet circuit of the artificial organ, and the body fluid of the artificial organ. This body fluid treatment device is characterized in that an extracorporeal circulation body fluid circuit is formed by connecting and integrating an outlet and a body fluid lead-out circuit so as to communicate with each other.

(Function) In the device of the present invention, at least the body fluid inlet and outlet of the artificial organ are connected in advance to the male (or female) connector unit formed integrally in the form of a block through a tube, so that at least the body fluid introduction circuit is connected in advance. Connection can be made reliably and without error simply by connecting the end of the body fluid lead-out circuit to the female (or male) connector unit to which it has been connected in advance.

(Example) Next, an example of the device of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart showing an example of the device of the present invention, in which the ends of tubes E, F, and G connected to the blood inlet, blood outlet, and plasma outlet of the plasma separator 1 are blocked by three connector members. It is connected to a male connector unit 10 integrally molded into a shape. The male connector female connector unit connects the blood introduction circuit A through the blood pump 2, the blood output circuit B, and the plasma discharge circuit C through the plasma pump 3.

The male connector unit 10 is usually equipped with a plasma separator 1.
A tube connected to at least a blood inlet and an outlet of the blood is aggregated. It is preferable to consolidate all of the circuits connecting the fluid inlets and outlets normally provided in a plasma separator into a male connector unit. For example, the first
As shown in the figure, a plasma outlet provided in a plasma separator 1 is connected to a male connector unit via a tube G.

Further, when detecting the plasma pressure in the space inside the housing, a pressure detection port provided in the plasma separator is connected to the male connector unit 10 via the tube H. In that case, plasma pressure can be measured by connecting tube I to which pressure detector 11 is connected to the female connector unit.

In the present invention, the plasma separator 1 is sterilized, shipped, and handed to the user in an integrated state with a male connector unit 10 connected through a tube as shown in FIG. The user can easily assemble the body fluid treatment device on site by connecting the male connector unit 10 to the female connector unit connected to the end of the blood circuit.

FIG. 3 is a perspective view showing the structure of the male connector unit. At the bottom of the unit are tubes E, F, G, and H connected to the blood inlet, outlet, plasma outlet, and pressure detection port of the plasma separator. are connected, and four connectors are provided protruding from the top to which tubes connected to each circuit and pressure detector are connected. Each circuit is connected to the four connectors mentioned above. Reference numeral 12 denotes an outer cylinder surrounding three connectors to which blood inlet/output circuits A and B and plasma discharge circuit C are connected. This prevents air from entering the circuit when the circuit is connected to a male connector unit that is connected to the male connector unit. Therefore, such an outer cylinder must be made to protrude from the upper end of the connector as shown in FIG.
The plasma separator and tube are filled with liquid to the point beyond the top of the connector. Therefore, the connector is always sealed with liquid, and there is no need to be careful about air intrusion when connecting a circuit to the connector. FIG. 4 shows an example of a female connector unit 17 that is fitted into the male connector unit 10 shown in FIG. has been done. Since each circuit is connected to the female connector unit 17 in advance, the connection between the circuit and the tube connected to the plasma separator can be completed in one operation, and erroneous operations such as incorrect connections can be eliminated. .

Note that the male connector unit and female connector unit described in the embodiments can be replaced with a female connector unit and a male connector unit, respectively.

(Effects of the invention) This invention does not require special skill when connecting artificial organs and extracorporeal circulation circuits, and even beginners can connect them reliably and efficiently without making mistakes. Moreover, it has become possible to minimize the risk of contamination from a sanitary perspective.
