  The present invention relates to a medical device that is installed and used on a column of a portable gantry using an external power supply. More specifically, the present invention relates to a medical device such as an infusion pump for injecting a drug solution into a patient, a syringe pump, or a blood purification device used in extracorporeal circulation type blood purification treatment.

  When injecting a drug solution into a patient at a medical facility, usually, a constant flow pump such as an infusion pump or a syringe pump is mounted on a portable mount with casters using a fixing jig so as to have an appropriate height. Attach and further connect the drug solution bag and tube. Then, the above-described pump is used as a power source to inject a drug solution necessary for treatment into the patient in a fixed amount.

  In addition, in blood purification therapy in which extracorporeal circulation is performed, the blood of a patient is taken out of the body via a tube, passed through a blood processing module such as a hemofilter or a hemodialyzer to purify the blood, and then the processed blood is purified. Is returned to the patient's body again. At this time, a blood purification apparatus is used to control the filtration flow rate and the dialysate flow rate to a constant value in addition to the blood flow rate, and constitutes a part of the extracorporeal circulation system. In some cases, it is installed at an appropriate height on a portable gantry.

  An infusion stand as shown in FIG. 1 is generally used as a portable gantry in a medical facility (this may be referred to as an “IV (intravenous) pole” or an “Illigator cradle”). Usually, it is composed of 3 to 5 feet of about 25 cm in length, one upright support of about 2 m or less, and a hanger such as a drug solution bag. The total weight is relatively light, about 3 to 8 kg, and since each foot has a caster, it is highly portable. Therefore, the sick patient can move freely in the facility during the infusion.

  However, the weight of a constant flow pump such as an ordinary infusion pump or a syringe pump weighs 2 to 4 kg, and the weight of a blood purification device is about 5 kg. Is quite large. Therefore, when installing them on an infusion stand, it was necessary to determine the installation position (height) while considering the center of gravity in order to prevent problems such as falling down. ) Was left only to the operator's experience. Therefore, if the installation position is too high, the whole infusion stand becomes unstable, and there is a risk that the infusion stand may easily fall over due to unexpected contact or the like.

With this, the medical device can be installed at an appropriate position (height) of the portable gantry using the display means attached to the power cord as an index, so that the center of gravity of the portable gantry becomes unstable and may fall. The medical device can be used safely.

  It is preferable that the display means is a scale provided over a predetermined range of the power cord. Thereby, an arbitrary height with respect to the floor of the device can be indicated within a certain range.

  Further, it is preferable that the display means is a marker attached to a predetermined position of the power cord. In this case, the power cord is provided with the markers at a plurality of locations, and each of the plurality of markers corresponds to a height of the portable device of a type to which the device can be attached, with respect to a floor of an appropriate device. Is preferred. Further, it is preferable that the plurality of markers are distinguished by a color or pattern, or an added symbol or character. Thereby, the specific height can be simply and appropriately indicated.

  Further, the portable mount is an infusion stand. The invention can be used particularly advantageously in infusion stands.

  According to the present invention, the medical device can be installed at an appropriate position (height) of the portable gantry using the display means such as a scale or a marker provided on the medical device as an index, so that the center of gravity of the portable gantry can be adjusted. The risk of falling due to instability can be reduced, and the medical device can be used safely.
