MEDICAL ASPIRATOR

摘要

The present invention is related to a medical aspirator and, in particular, to a medical aspirator comprising: a floor plate; a pressure plate disposed a certain distance away from the floor plate, and defining a discharge hole opened and closed by an opening/closing means; a coil spring installed between the floor plate and the pressure plate; a sealing membrane connecting the edges of the floor plate and the pressure plate, and defining a receiving space capable of receiving bodily fluid between the floor plate and the pressure plate; and a drainage tube connected to the pressure plate, for guiding bodily fluid generated from the body to the receiving space, and including a check valve therein enabling the fluid to flow only in the direction from the body toward the receiving space, wherein the medical aspirator has the effect of preventing contamination from outside air of bodily fluid extracted from the body and stored in the receiving space.

1. A medical aspirator comprising:
a floor plate 100; a pressure plate 200 disposed apart from the floor plate 100 by a certain distance and has a discharge hole 210 being opened and closed by an opening/closing means 220; a coil spring 300 installed between the floor plate 100 and the pressure plate 200; a sealing membrane 400 which connects an edge of the floor plate 100 and an edge of the pressure plate 200 and forms the receiving space “R” the bodily fluids between the floor plate 100 and the pressure plate 200; and a drainage tube 500 which is connected to the pressure plate 200 and guides the bodily fluids to the receiving space “R” and has a check valve 500b formed therein allowing the fluids generated from a human body to flow only in a direction toward the receiving space “R” from the human body,
wherein the opening/closing means 220 includes:
a fixing part 221 which is fixed around the discharge hole 210 of the pressure plate 200;a first strap 222 which is integrally connected to the fixing part 221;a fitting tube 223 which is integrally connected to the first strap 222 and is inserted into the discharge hole 210;a check valve 224 which is inserted within the fitting tube 223 such that the fluids are flowed only in a direction toward the outside from the inside of the receiving space “R”;a second strap 225 which is integrally connected to the fitting tube 223; anda stopper 226 which is connected to the second strap 225 and seals a top of the fitting tube 223 to which the check valve 224 has been inserted.
