するための医療用排出装置に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a medical evacuation device, which is used to eject gas and liquid from a body cavity such as the chest, collect liquid, measure the amount of the ejected amount, and calculate the total amount. The present invention relates to a medical evacuation device for monitoring recovery status.

Generally, 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 fluid.When attempting to inflate and recover the lungs, the tube connected to the catheter is There are two methods: one is to use a container that is sealed and has an air outlet near the top, and the other is to connect a flutter valve kit that serves as a check valve to the catheter, and then connect a bag or bottle-shaped container to collect fluid. It is being done.
前者の方法は、水封の水を容器内に収納してお
くため、水の供給及び流出防止、排液による水位
上昇に伴う水封管の上部への移動等多くの操作と
注意が必要であり、特に水封のための水を容器に
入れるおくことは携帯し持歩くのに不便である。 The former method stores the water in the water seal in a container, so it requires many operations and care, such as supplying water, preventing it from flowing out, and moving the water seal to the top of the pipe as the water level rises due to drainage. However, it is inconvenient to carry water, especially for water seals, in a container.
後者の方法は、逆止弁となるフラツターバルブ

肺の膨脹・回復及び外気による汚染と言う点では
問題が潜在している。 The latter method is complicated in that it requires connecting the flutter valve kit, which serves as a check valve, to the container, and the existing flutter valve kits are simply uneven tube-shaped sheets. However, the backflow prevention effect against discharged gas and liquid is not sufficient. This tendency is particularly noticeable under slightly negative pressure (5 to 30 cmH 2 O), which is commonly used.
There are potential problems with lung inflation and recovery and contamination with outside air.

点がある。 Furthermore, these methods have the disadvantage that they are not designed to be particularly designed to allow connection to necessary suction devices, etc., and are difficult to respond to quickly depending on the content of the process.

The present invention incorporates a reversal valve that is more reliable and highly effective, has a monitor valve that can sense the flow of discharged gas and observe the recovery status, and has a suction connection port. It is an object of the present invention to provide a medical evacuation device that can perform natural drainage of gas and liquid in a body cavity by itself, can monitor the state of lung expansion in pneumothorax, etc., and can also be connected to a suction device to perform suction drainage. This is the purpose.

That is, the present invention is a hard hollow container made of plastic, which has an inlet for gas and liquid from the body cavity in the upper part, and a soft flat tube in the lower part of the inlet, and both ends of the container have an inlet. A check valve that is sealed diagonally to prevent backflow of gas and liquid is connected, and a monitor valve that indicates the flow of gas is installed at the top of the container, and a connection port is installed at the top of the monitor valve. This is a medical evacuation device characterized by having:
以下図面により、本発明の一実施例となる医療

The hard hollow container 1 has an inlet 2 near the center of the upper part, and a flutter-shaped check valve 3 is connected to the lower part of the inlet to prevent backflow. The container 1 serves as a collection part for the discharged liquid, and by marking the wall with scales, the amount of liquid discharged can be measured.

良い。 The check valve 3 is a soft, flat tube as shown in FIG.
It is connected to the connection port 6 at the bottom of the. Connection port 6
The flow of gas and liquid can be discharged by pushing the inner surface of the end 4 of the flat tube as shown in Figure 2b, but the flow from the opposite direction can be discharged through the flat tube as shown in Figure 2c. Since the inner surface of the distal end 4 of the tube is tightly closed, no inflow is possible. This structure is basically the same as the conventional flutter type check valve, but the check valve 3 used in the present invention
In this case, both ends 7 of the distal end 4 of the flat tube are sealed diagonally as shown in Fig. 2a, and the width of the opening is narrowed, so that the inner surface of the distal end 4 can maintain tightness. It's summery. More preferably, the wall thickness of the end portion 4 of the flat tube is reduced, for example, from 0.3 to
A value of 0.6 mm is appropriate, and by implementing these measures, a better backflow prevention effect can be obtained. The flat tube may be a tube formed by extrusion molding or the like, or may be formed by stacking two sheets and joining both sides.
