Description

[Detailed description of the invention] [Field of commercial application] The present invention is a medical evacuation device, which is used to eject gas and liquid from body cavities such as the chest, collect liquid, and measure the amount of the ejected amount. The present invention also relates to a medical evacuation device for monitoring the state of recovery.

[Prior art]

In medical procedures for the chest, such as pneumothorax, a catheter is placed in the thoracic cavity and connected to a container to drain gas and liquid, and when attempting to inflate and recover the lungs, a catheter is connected to the catheter. A method using a container that is sealed with water and has an air outlet near the top, and a flutter valve kit that serves as a check valve is connected to the catheter, and a bag or bottle-shaped container is also connected to collect the fluid. The method is being used.

The former method stores water in a water seal in a container,
Many operations and precautions are required, such as supplying water and preventing it from flowing out, and moving the water sealing pipe to the top as the water level rises due to drainage. It is inconvenient to walk.

The latter method is complicated in that it requires connecting a container with a 72 ivy pulp kit that serves as a check valve;
The existing 72 ivy pulp kit is simply a tube-shaped sheet of side wood, and does not have a sufficient anti-return effect. This tendency is particularly noticeable under slightly negative pressure (5 to 30
(7AH, 0th place) is remarkable, and there are potential problems in terms of lung expansion/recovery and contamination by outside air.

However, depending on the details of the treatment, it is difficult to respond quickly.

[Purpose of the invention]

The present invention has a built-in more effective check valve, a monitor valve that can sense the flow of discharged gas and observe the state of recovery, and has a suction connection port (secondly, this device can be used alone). The purpose of the present invention is to provide a medical evacuation device that can perform natural drainage of gas and liquid in body cavities, monitor the state of lung expansion in cases such as pneumothorax, and can also be connected to a suction device to perform suction drainage. That is.

[Structure of the invention]

That is, the present invention is a rigid hollow container made of plastic, which has an inlet for gas and liquid from the body cavity in the upper part, and a check valve in the lower part of the inlet to prevent backflow of the gas and liquid. This medical discharge device is characterized in that a monitor valve indicating the flow of gas is installed at the top of the container, and a connection port is provided at the top of the monitor valve.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A medical evacuation device according to an embodiment of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a schematic diagram of a discharge device according to an embodiment of the present invention. The hard hollow container (1) has an inlet (2) near the center of the top.
A seven-rattle check valve (3) is connected to the bottom of the inlet to prevent backflow.

The container (1) serves as a collection part for the discharged liquid,
By marking the wall with scales, the amount of liquid discharged can be measured.

The check valve (3) is a soft, flat tube as shown in Fig. 2, and its distal end (4) is in close contact with its inner surface, and its base (5) is pushed apart. Inlet (2), l
It is connected to the connection port (6) at the bottom of the. Connection port (6
) can be discharged by pushing the inner surface of the flat end (4) of the tube as shown in Figure 2 (b), but the flow from the opposite direction can be discharged as shown in Figure 2 (C). Since the inner surface of the flat end portion (4) of the tube is tightly closed, no inflow is possible. Although this structure is basically the same as the conventional 7-latch check valve, the check valve (3) used in the present invention has a flat tube at the tip of the distal end (4). Both ends (7) are diagonally sealed as shown in FIG. 2(a), so that the inner surface of the end part (4) can maintain tightness.

More preferably, the end portion (4) of the flat tube has a thick wall and a monitor valve (8) is provided for releasing suddenly generated positive pressure. Although the shape is not particularly limited, a spherical shape, a flat valve shape, etc. are suitable.A suction connection port (9) is provided at the upper part of the monitor valve (8).

The evacuation device according to the present invention is used by connecting a catheter (12) indwelled in a body cavity to the inlet (inflow port) via the tube (1) and the connection port (11).
The pressure regulating suction device (14) is connected to the suction connection port (9) via the connection tube (13), and suction drainage is being performed.

Further, FIG. 4 shows a state in which an exhaust mechanism (15) capable of suctioning and exhausting is connected to the suction connection port (9). The exhaust mechanism (15) may be in the shape of a bellows as shown in Fig. 4 or in the shape of an elastic ball. 16) and its recovery force generates a suction force to suck gas from inside the container (1) through the suction valve (16), and then discharge it from the exhaust valve (17).

Furthermore, when observing the healing of the chest wound and the recovery of lung expansion, for example, if the exhaust mechanism (15) remains contracted even after the force is removed, do not take any action. It shows that there is no gas leakage in the lungs, and is useful as a guideline for determining the state of recovery.

〔Effect of the invention〕

As described above, the evacuation device according to the present invention can be used for both the intermittent drainage of gas and liquid in the body cavity and the suction drainage performed by connecting with a suction device or an exhaust mechanism. You can observe the state of gas discharge from the body and know the progress of recovery. In addition, by applying a new design to the check valve, the effect of preventing backflow of discharged gas or liquid has been improved, making it useful as a medical discharge device.
