First Claim
Patent Images
1. A delivery apparatus for medical fluid fabricated in a box type with a syringe, the delivery apparatus comprising:
- a case including a body, an upper portion of which is open and in which a battery receptacle and a syringe receptacle are integrally formed;
a gear box driven by a motor and including a rotating shaft for rotatably engaging with a moveable shaft is introduced into and withdrawn from a syringe receptacle;
a cover with a recess;
a keypad for controlling an operation of the moveable shaft is installed in the recess of the cover and is fixed by a pressing part and a cover plate, and the cover and the body are screw-fastened in a state in which coupling protrusions and thereof are engaged with each other such that the cover is detachably coupled with the body;
a protruding rim having a flange formed at an edge of a rubber pad covering a substrate of the keypad received in the recess; and
a recess rim and a support surface formed on an outer peripheral surface of the recess such that the recess rim and support surface are engaged with the protruding rim, thereby increasing surface tension due to a double-engagement and enhancing a water-proof function,wherein the gear box has a supporting guide formed on the body making contact with the gear box to prevent vibration caused by a rotation of the motor from being transferred into the moveable shaft, and wherein a predetermined gap is formed between the gear box and the body to absorb vibration in a case where the gear box comes close to contacting the body.
