Problems solved by technology

In addition, since this clip has a simple structure with a vertical groove connected to a large-diameter hole, the infusion tube in the vertical groove can be easily moved by an external force such as the impact force when it is dropped, and the blocked state is easily released. Therefore, there is a problem in safety, and since there is no holding feeling obtained by applying an appropriate load when attaching and detaching the clip, the operability is poor.

Embodiment Construction

[0065] Next, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

[0066] In the following description, the infusion method proposed by the applicant of this patent and disclosed in Japanese Patent Application Laid-Open No. 9-151856 will be explained on the premise. This infusion method is a peristaltic finger-shaped member method, which makes the upstream and downstream sides of the infusion tube in a completely flattened occlusion state through each finger-shaped member, so that the part on the way to be occluded is not completely crushed, thereby eliminating the need for infusion. Influenced by tube wall thickness, infusion is performed with good precision.

[0067] Of course, it is not limited to this method, and the present invention can also be applied to infusion pumps such as peristaltic finger-shaped member-type infusion pumps or roller-type infusion pumps belonging to other types of infusion devices. Infusio...

Abstract

The invention provides an infusion device. The clip used on the infusion device has a main base, a sub-base, and a junction; the main base and the sub-base form two occlusions for occluding the infusion tube, and the sub-base is elastically The force of the support part can move toward the standby position; the engaging part can make the clip in the closed state by engaging the main base and the sub-base, and can return the clip to the position by pushing the pressing surface of the sub-base. standby position. The clip loading unit to which the above-mentioned clip is installed is arranged on the lower side of the infusion tube blocking unit. The infusion tube blocking unit closes the above-mentioned infusion tube with the opening and closing of the door. The sliding contact of the side surfaces of the subbase can generate a moderate frictional force, thereby applying a force to the subbase to move in the direction of the occluded state.

Description

technical field [0001] The invention relates to an infusion device and a clip used for the infusion device. The above-mentioned clip is installed in the infusion device. The clip is installed on a filling unit and can be freely assembled and disassembled. Occlusion is performed to allow infusion to proceed when the clip is returned to the standby position, disengaged. [0002] The present invention also relates to an infusion device with the following clips installed on the filling unit, the clips are special clips for special infusion tubes with ensured infusion accuracy, or universal clips for general infusion tubes. Although the infusion accuracy of the infusion tube cannot be guaranteed, it is connected to the drip measurement unit for use. Background technique [0003] In an infusion device, for example, a peristaltic infusion device works like this. After opening the door of the push plate that pushes the infusion tube, the infusion tube is set, and then the infusion...
