[0080] figure 1 A is an exploded view of the fluid delivery device 1 of the first embodiment, figure 1 B is an explanatory diagram of the pump unit 40. figure 2 It is a cross-sectional view of the fluid conveying device 1. For illustration, the side where the fluid transport device 1 is attached to the living body is the lower side, and the opposite side is the upper side.

[0081] Such as figure 1 As shown, the fluid delivery device 1 of the first embodiment includes a main body portion 10, a box 20, and a patch portion 30. The main body portion 10, the box 20, and the patch portion 30, such as figure 1 As shown in A, although it can be separated, it is assembled into a whole when in use. In addition, the lower surface of the patch portion 30 of the fluid transport device 1 is attached to a living body, and the cartridge 20 stores fluid, for example, for injecting a liquid medicine such as insulin into the living body. In addition, the fluid conveyed by the fluid co...

no. 2 approach

[0101] Figure 4 It is an explanatory diagram of the catheter 31(2) of the second embodiment. In the second embodiment, only the structure of the catheter is different from the first embodiment. The width of the electrode member 36(2) becomes shorter in the direction perpendicular to the axial direction of the catheter 31(2). The electrode member 36(2) is provided in a part of the outer peripheral surface of the) in the circumferential direction. Thereby, the outer peripheral surface of the duct 31(2) is exposed from the upper end to the lower end, and the range of the fluid flowing inside the duct 31(2) can be visually confirmed. Therefore, it is easier to confirm the state of the fluid in the duct 31(2). In addition, as in the first embodiment, in the catheter 31(2) of the second embodiment, the electrode member 36 is not provided at the lower end, and since the electrode member 36 extends in the axial direction, the catheter 31 can be determined more accurately. The except...

no. 3 approach

[0103] Figure 5 It is an explanatory diagram of the catheter 31(3) of the third embodiment. The third embodiment differs from the first embodiment only in the structure of the catheter, and the electrode member 36(3) is embedded in the catheter 31(3) so as not to contact the fluid flowing inside the catheter 31(3). In addition, in order to more reliably contact the electrode member 36(3) with the fluid and the living body, the electrode member 36(3) is exposed from the end surface 31a of the catheter 31(3) inserted into the living body side (lower side). At this time, as Figure 5 As shown, since the current from the connecting needle 26 flows through the fluid A and the biological body B to the electrode member 36(3), it can be determined that the catheter 31(3) is abnormal. In addition, since the outer peripheral surface (except the axial end surface) of the electrode member 36(3) is covered by the catheter 31(3), it is possible to suppress the occurrence of noise caused by ...

Abstract

A fluid transport apparatus (10) includes: a first electrode (36) provided on the insulating transporting tube which constitutes part of a flow channel in which conductive fluid is transported, and configured not to come into contact with the fluid in the flow channel a second electrode (26) configured to come into contact with fluid in the flow channel; and a determining unit connected to the first electrode and the second electrode, and configured to determine a trouble of the transporting tube. Accordingly, the trouble of the transporting tube is determined.

Description

Technical field [0001] The present invention relates to a fluid delivery device, a fluid injection device, and an abnormality determination method for a delivery pipe that delivers fluid. Background technique [0002] As a fluid conveying device, for example, as described in Patent Document 1, a known micropump is provided with a plurality of fingers between a tube for conveying fluid and a cam, and the plurality of fingers are sequentially pressed while rotating the cam. The tube is compressed by a number of fingers to convey the fluid in the tube. [0003] As in the fluid delivery device described above, for example, in order to inject fluids such as insulin into a living body, by placing a catheter in the living body, the fluid can be regularly injected into the living body. However, it is impossible to regularly inject fluid into the living body without noticing abnormalities such as falling off or clogging of the catheter or the fluid-conveying tube.
