Liquid Infusion Apparatus
First Claim
1. A liquid infusion apparatus, comprising:
- a main body having an opening;
a door installed on the main body so as to be openable, wherein when the door is closed, the door faces the opening with a liquid infusion tube interposed between the door and the opening and supports the liquid infusion tube;
a finger module comprising a plurality of fingers installed in the main body so as to be movable forward and backward relative to the opening, the fingers moving in conjunction with a cam shaft in a wiggling manner in which the fingers successively move forward to the opening and compress a portion of the liquid infusion tube through the opening;
an elastic member applying elastic force to the finger module and biasing the finger module forward so that the liquid infusion tube is elastically compressed by the fingers; and
cam shaft drive means rotating the cam shaft so that the fingers move in conjunction with the cam shaft in the wiggling manner.

Abstract
The present invention relates to a liquid infusion apparatus, including: a finger module provided in a main body such that the finger module can elastically move backward from a liquid delivery tube; a tube clamp, in which two clamp bodies spaced apart from each other approach each other by means of restoring force of an elastic member upon the opening of a door during infusion, so as to compress and block the liquid delivery tube; and a tube blockage detection device which detects whether the liquid delivery tube is blocked by a cause, for example, when the outlet-side portion of the liquid delivery tube, which delivers medicinal liquid pumped by a liquid pump during infusion, is bent.

7. A liquid infusion apparatus, comprising:
-
a door installed on a main body so as to be openable, wherein when the door is closed, the door faces the main body with a liquid infusion tube interposed between the door and the main body and supports the liquid infusion tube; a finger module comprising a plurality of fingers moving in conjunction with a cam in a wiggling manner, the fingers facing the door with the liquid infusion tube interposed between the door and the fingers, the finger module being mounted to the main body by elastic means such that the finger module is able to successively compress a portion of the liquid infusion tube using the fingers that move in the wiggling manner and be elastically retracted from the liquid infusion tube; and drive means for operating the cam so that the fingers move in conjunction with the cam in the wiggling manner.

8. A liquid infusion apparatus comprising:
- a main body in which a wiggling liquid infusion pump is installed, the liquid infusion pump compressing a liquid infusion tube to conduct liquid infusion;
a door installed on the main body so as to be openable, wherein when the door is closed, the door faces the liquid infusion pump with a liquid infusion tube interposed between the door and the liquid infusion pump and supports the liquid infusion tube that is compressed by the liquid infusion pump;
a tube clamp blocking the liquid infusion tube when the door opens and releasing the liquid infusion tube that has been blocked when the door is closed,wherein the clamp comprises;
a first clamp body disposed between the main body and the door that is closed, and facing the main body with the liquid infusion tube interposed between the tube clamp and the main body;
a second clamp body facing the first clamp body with the liquid infusion tube interposed between the first clamp body and the second clamp body; and
an elastic member applying elastic force to the first and second clamp bodies so that the first and second clamp bodies move toward each other and compress the liquid infusion tube,wherein the first clamp body comprises a leg protruding toward the second clamp body and coming into contact with the main body, and the second clamp body comprises a leg protruding toward the first clamp body so that when the door is closed, the leg of the second clamp body comes into contact with the door whereby the second clamp body moves away from the first clamp body, and the main body has a space-forming depression in a predetermined portion facing the second clamp body, the space-forming depression defining a space in which the second clamp body can move away from the first clamp body. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A liquid infusion apparatus, comprising:
-
a main body provided with a liquid infusion pump conducting a wiggling motion that successively compresses a portion of a flexible liquid infusion tube for transferring a medical liquid; a door installed on the main body so as to be openable, wherein when the door is closed, the door faces the liquid infusion pump with a liquid infusion tube interposed between the door and the liquid infusion pump and supports the liquid infusion tube that is compressed by the liquid infusion pump; a movable member facing the closed door with a portion of an outlet-side of the liquid infusion tube interposed between the movable member and the door and provided for transferring the medical liquid, the movable member installed in the main body so as to be movable forward and backward with respect to the portion of the outlet-side of the liquid infusion tube so that when the movable member moves forward, the movable member approaches the portion of the outlet-side of the liquid infusion tube; an elastic member applying elastic force to the movable member and biasing the movable member forward so that the movable member can approach the portion of the outlet-side of the liquid infusion tube; displacement detecting means detecting whether the movable member has been moved backward by expansion of the portion of the outlet-side of the liquid infusion tube which is caused by congestion of the medical liquid transferred by the liquid infusion pump; and a control unit determining whether the liquid infusion tube has been blocked depending on a result of the detection of the displacement detecting means. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
