まり違いはない。An example of the prior art will be explained with reference to FIGS. 1 and 2. The rotation of a motor 1 fixed to the substrate is transmitted to the roller holder 6 through a key 31 and a keyway 32. The roller holder 6 has
A plurality of rollers 3 are rotatably attached to a shaft 4.
The tube 7 is sandwiched between this and the guides B and k, and is compressed by the spring 5. The guide tube through which the volume 4 sandwiched between the two O-rollers 3 is transported by the rotation of the motor 1 is shown fixed to the substrate LHC with bolts 8, but the operation of fitting the tube 7 is an example. In order to overcome this drawback, if the guide B is mounted so as to be rotatable around the shaft, the tube 7 can be opened as shown by the chain double-dashed line, placed in the groove 17, and the setting pin drilled in the hole 11. It is thought that it will fit. If you pull knob 9, the setting pin will come off against the spring IOK, but there is not much difference in that attachment and removal are complicated and time consuming.

が賛点である。The present invention provides a pump structure in which complex infusion channels are arranged in a planar manner, and when a large number of roller pumps are attached to a single cup, the entire pump circuit is closed at once. For rounding, the roller that crushes the infusion channel should be pressed against a plane perpendicular to the drive shaft.
In other words, the advantage is that the structure has a pressing force in the direction of the drive shaft.

There is a pin U at the tip of the drive shaft 2, and the pin 4 engages with this to transmit rotation to the roller holder 6. The roller holder 6 has several rollers 3 rotatably supported on the shaft 4, and the roller holder 6 and the spring holder have a spring 5.
It is rotated by the drive shaft 2 through a bearing 21. Further, the bearing n is capable of sliding and rotating in the axial direction. The elastic infusion tube 7 on the substrate V is placed in a position where it is crushed by the roller 3, and when pressed to create an appropriate gap, the roller holder 6 rotates.
The infusion is divided into volumes of 27 using two rollers 3. The cover 29, which fixes the case 4 of the roller pump, can be opened as shown by the two-dot chain line centering on the transport column. In this state, setting the wheel fluid tube 7 is easy.

1どチューブのセントが繁雑で時間がかかる。To infuse blood, a roller pump is often used, which is a flexible plastic tube that is squeezed with rollers to prevent germs from infecting the body by disconnecting it from the outside air. Moreover, in order to avoid problems such as blood type incompatibility, the tubes need to be set carefully since they are disposable. It is also a complex device that requires multiple infusion pumps.
1st tube is complicated and time consuming.
