Abstract: The present invention provides a drainage tube introducer wherein while a drainage tube is fitted over an introducing end portion (42) protruding through a pin hole (32) and is introduced through an incision portion (4) into an infected portion (2) in cooperation with the introducing end portion (42), a stop block (52) is pressed by pushing a sleeve (70) frontward, which bends an operating lever (50) made of an elastic material to release the stop block (52) from a stop hole (38). Accordingly, a pin (40) is moved rearward by an elastic member (60) to withdraw the introducing end portion (42) protruding through the pin hole and to separate the drainage tube introduced into the infected portion (2) from the introducing end portion (42).

Abstract: An acoustic resonator is provided in which loss of acoustic waves in a transverse direction may be reduced through a cavity formed in an acoustic resonance unit including a first electrode, a piezoelectric layer, and a second electrode, and in which acoustic waves in a longitudinal direction may be reduced by forming an air gap between the acoustic resonance unit and a substrate. Whereby, a quality factor may be improved.

Abstract: Disclosed is a drainage tube that includes: a conduit member which has a first end, a second end, and a drainage passage disposed between the two ends. The first end is inserted into a diseased part of a Bartholin's duct abscess through an incision. A first wing member is provided on an outer circumference at a side of the first end and prevents the conduit member inserted into the diseased part from being separated. A second wing member is provided on the outer circumference at a side of the second end and restricts the depth to which the conduit member is inserted into the diseased part. Pus or the like may be smoothly drained from the diseased part while the incision heals.

Abstract: The present invention provides a medical fluid dispenser. Medical fluid to be additionally administered to an administration target such as a patient is supplied into a balloon, when a button is operated. As medical fluid is supplied into the balloon, the balloon inflates to store the medical fluid therein. The inflated balloon contracts using its own restoring force to discharge the medical fluid that has been stored therein. Thereby, an additional administration of medical fluid can be continued for a predetermined time period without the need for repeatedly operating the button.

Abstract: The present invention relates to a method of managing a history of the injection of a medicinal fluid. More particularly, the present invention relates to a method of managing a history of the injection of a medicinal fluid, which is capable of managing the history of the injection of a medicinal fluid in an apparatus for injecting a medicinal fluid that automatically injects a predetermined volume of medicinal fluid into a vein or epidural space of a patient in order to manage the pain of the patient.

Abstract: The present invention provides an apparatus for controlling an administration rate of medical fluid. The apparatus is configured such that medical fluid supplied into a single inlet tube is divided by a plurality of capillary tubes into several streams of medical fluid which have different flow rates, and the tubes through which the streams of medical fluid flow are switched by a multi-valve to select one of various flow pathways. Therefore, the flow rate of medical fluid can be quantitatively selected so that an appropriate amount of medical fluid is administered to an administration target, such as a patient, along the selected flow pathway.

The automatic locking valve comprises a valve housing defined with a space and formed with input and output ports for intaking and discharging the medication, a spool-shaped on/off member having a diameter smallest at the center thereof and being tapered to linearly increase toward upper and lower portions of the on/off member so that the on/off member moves up and down depending on a closed state of the door, and a membrane attached to the space of the valve housing such that the membrane expands toward a lower portion of the space due to an elasticity of the membrane when the tube is blocked. The medication can be safely and accurately administered under a condition of installation with the door closed above the tube.
