Brief Patent Description - Full Patent Description - Patent Application Claims
TECHNICAL FIELD [0001] The present invention relates to a infusion device such as a syringe pump or a infusion pump for administering a drug to a patient, and more particularly to a infusion pump which presses a infusion tube to infuse a liquid drug. BACKGROUND ART [0002] For infusions conducted in medical institutions or medical care at home, problems sometimes occur in setting a infusion flow rate and a dose to be infused. Consequentially, safer infusion devices are required. In conventional infusion devices, an operation panel is used as an user interface that includes a setting input key for setting a flow rate, a volume to be infused or various warnings and a display unit for displaying them (Japanese Patent Laid-Open No. 9-154943 and Japanese Patent Laid-Open No. 2000-300667). DISCLOSURE OF THE INVENTION [0003] Conventional devices, however, have problems setting an input suitable for a field of use cannot be performed (for example, setting the input for many flow rates). The present invention is achieved to solve the conventional problems, and has an object to provide a infusion device that is easily usable by use with high safety, and more particularly, a infusion device including a user interface capable of providing a necessary alarm to a user (a healthcase worker) to eliminate the problems in setting a dose and flow rate before a infusion and allowing the user to set the alarm condition. [0004] The above described object is achieved by a infusion device including: a setting unit for setting a dose and a infusion flow rate, or the like; and a display unit for displaying the dose and the infusion flow rate, or the like, wherein when the infusion flow rate (mL/h) is input via the setting unit, the flow rate is increased or decreased step by step followed by a buzzer sound for each press of an input key. The above described object is also achieved by a infusion device including: a setting unit to set a dose and a infusion flow rate, or the like; and a display unit to display the dose and the infusion flow rate, or the like, wherein thresholds of the lengths of detected air is classified into two predetermined stages so that either thereof can be selected. The above described object is also achieved by a infusion device including in a door: a setting unit to set a dose and a infusion flow rate, or the like; and a display unit to display the dose and the infusion flow rate, or the like, wherein setting an input in the setting unit is prevented while the door is kept opened and/or during the start of a infusion (during a infusion operation). [0005] As described above, according to the present invention, a infusion device is provided that allows a user to set infusion conditions safely and reliably, and also the easy setup or adjustment or selection of a necessary alarm (warning) condition via a user interface including an operation panel. Further, detailed organization of the present invention will become more apparent from the following description of the best implementation of the invention and its accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0006] FIG. 1 is an overall appearance perspective view of a infusion device according to the present invention with its door being opened; [0007] FIG. 2 shows an operation switch panel according to the present invention; [0008] FIG. 3A is a perspective view of a door side sensor (a transmitting element) 31 facing a base side sensor (a receiving element) 30; [0009] FIG. 3B is a sectional view of a state where door 4 is closed to hold a infusion tube 2; [0010] FIG. 4 shows the flow of air detection according to the present invention; [0011] FIG. 5A shows the rear surface of the infusion device 1; [0012] FIG. 5B is a perspective view of the bottom surface of the infusion device 1; [0013] FIG. 6 is a block diagram of the infusion device according to the present invention; and [0014] FIG. 7 shows the flow of a subroutine for setting inputs according to the present invention. DESCRIPTION OF SYMBOLS [0015] 1 infusion device [0016] 2 infusion tube [0017] 4 door [0018] 6 operation indicator [0019] 8 the drip number setting switch [0020] 9 volume to be infused/volume infused setting switch [0021] 11 flow rate setting switch [0022] 13 check timing display unit BEST CONFIGURATION FOR CARRYING OUT THE INVENTION [0023] Now, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an appearance perspective view of a state where a peristaltic infusion device 1 as an example of a infusion device is secured to a infusion pole 90 with its door being opened, FIG. 5A is a rear perspective view, and FIG. 5B is a bottom perspective view. FIG. 6 is a block diagram. In the state in FIG. 1 a flexible infusion tube 2 (see FIG. 2) described later is set in the infusion device. The infusion device is used with the door 4 being closed. In this state of use, the outline dimension of a device body excluding handle 5 provided in the upper unit and the right and left protrusions 3a (the right one only is shown in FIG. 1) is about 19 cm wide, about 16 cm high, and about 16 cm deep. [0024] The infusion device 1 has securing fittings 91 on its a rear surface, into which a securing knob 92 is screwed so as to be secured to the infusion pole 90 as shown in FIG. 1. The infusion device 1 can be secured at any height of the infusion pole 90 as required for particular use. Further, the infusion device 1 has four rubber feet 93 secured to its bottom surface so that the infusion device 1 can also be used on a desk beside a patient after being removed from the infusion pole 90. [0025] Thus, the device is designed so that a user (an operator such as a healthcare worker, for example, a doctor or a nurse) presses each switch with his/her thumb with the remaining fingers resting on back sides of the right and left protrusions 3a for an easy pressing of the various switches in order to improve usability when setting (mounting) the infusion tube 2 (see FIG. 2). The right and left protrusions 3a (the right protrusion 3a only is shown in FIG. 1) are integrally molded with a body base 3 that is made of reinforced plastic or an aluminum die casting, resistant to impact and have vertically sufficient lengths as shown. With the right and left protrusions (projections) 3a, a body facing cover 12 of the infusion device 1 has a wider width than the door 4, and thus even if the infusion device 1 falls onto the floor, the body facing cover 12 hits the floor before the door 4 hits the floor because of the center of gravity of the infusion device 1, thereby protecting the infusion device 1 and the door 4 from strong impact when falling.
