Description

Medical Suction Unit

The present invention relates to a medical suction device, and more particularly, a negative pressure plate composed of an upper plate, an elastic member, and a lower plate in the order of an upper plate, an elastic member, and a lower plate is provided inside a suction bag provided in the shape of a closed bag made of a transparent and flexible material. The lower plate is fixed and the elastic member is compressed, and when the patient's secretions are drained, the coupling between the upper plate and the lower plate is released only by lightly folding the bends provided on one side of the upper plate and the lower plate, and the elastic force of the elastic member It relates to a medical aspirator that allows the upper and lower plates to be spaced apart from each other, and at the same time the inside of the suction bag expands to form a low vacuum negative pressure to suck the patient's secretions from the affected part into the suction bag.

In general, a medical aspirator is a device that forcibly suctions and discharges secretions from a surgical site of a patient or an airway of a critically ill patient by using a low vacuum pressure.

A medical aspirator consists of a suction container that provides suction and stores the body fluid to be sucked, a drain tube that is inserted into the human body to induce suction of the body fluid, and a connection tube that connects the suction container and the drain pipe.

In this case, as a method of sucking the body fluid, a manual vacuum forming method and a pre-vacuumed method are generally used.

Among them, the medical aspirator using a manual vacuum forming method sucks body fluid by forming a vacuum in the suction container by the return property of the elastic member when the air in the container is removed by pressing by hand.

However, in such a manual vacuum forming type medical aspirator, the suction pressure is determined according to the degree of pressing, and the suction pressure is rapidly reduced according to the suction of body fluid, and the prescribed amount of the suction container cannot be filled due to the sudden pressure decrease, etc. There is a problem of

In addition, it has to be pressed from the top to the bottom, and since a coil spring with high elasticity is used to generate negative pressure, it is difficult for nurses, mostly female, to use it. In particular, in a state where the upper pressure plate is pressed, that is, in a state where a continuous strong force is maintained, an additional operation of blocking the stopper must be made to close the discharge passage, which is more difficult for nurses to use.

On the other hand, medical aspirator using the pre-vacuum method is produced by pre-evacuating the suction container designed to withstand pressure during the manufacturing process. There are advantages such as filling the capacity of the suction container.

However, there was a problem that it was difficult to check the vacuum state inside the suction container with the naked eye from the outside before use, and it was difficult to grasp the degree of vacuum inside the suction container even during use.

In addition, in the suction system according to the prior art, a regulator is installed to control the amount sucked by the suction device, but since it is developed for a thin tube, when applied to a suction device using a thick tube, it is difficult to control and the elasticity of the tube There was a problem in that it was difficult to maintain a properly controlled state.

In addition, since the connection of the tube applied to the medical aspirator system according to the prior art is used by inserting a flexible tube into a connector, etc., there is a problem that the connection is released by an external force and is released.

As such, the prior art contains a common problem that not only requires a lot of force, but also has many difficulties in simple and quick operation.
