Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for sucking and exuding body fluid such as exudate and drained blood (hereinafter referred to as "drainage") from a wound cavity of a human body, and for adhering tissue inside the wound cavity. The present invention relates to a portable medical suction liquid collector.

[0002]

2. Description of the Related Art It has been well known that a medical suction collector is used to suck and discharge body fluid (drainage) discharged from a human wound cavity such as an incision wound or a surgical wound. In this case, a tube for guiding the drainage of the drainage fluid is inserted into the wound cavity and connected to the suction collector, and the drainage fluid in the wound cavity is sucked by the negative pressure generated in the suction collector. Collected and stored in the collector.

The portable type suction collectors that have been known up to now have a mechanism for generating a negative pressure in the container.
It is roughly divided into the following three types. That is, the inside of a rigid closed container called a vacuum bottle is decompressed in advance, an elastic and expandable container is compressed in advance to reduce the internal volume, and the elastic recovery force of the container is used to make a container. A device that generates negative pressure inside, and a rigid container has a built-in elastic member (balloon, etc.) that is expandable and contractible. By expanding this elastic member, the inside of the rigid container is exhausted, and the container contracts due to the force of the elastic member. It is to generate a negative pressure inside. However, the first type has a fatal drawback that the suction force sharply decreases as the drainage is accumulated. In addition, such a medical suction device is generally used 2-3 times after the operation.
It is used continuously for up to 7 days a day. During this period, it is necessary to perform suction operation such as recompression or reexpansion several times, but in the second and third types, , It is necessary to discard the drainage collected so far. In addition, there are many problems such as the inability to measure the amount of drainage during suction, and the risk of drainage of drainage back into the wound cavity if an operation is mistaken.

As a means for solving such problems,
A first chamber for suctioning and storing exudate (body fluid) from the human wound, and a second chamber for generating suction force by the contracting force of a balloon member that is provided in a rigid container and is expandable and contractible. There has been proposed a medical suction liquid collector (Japanese Patent Laid-Open No. 61-131751) in which the second chamber and the second chamber are in fluid communication with each other. Although the storage part and the suction source are divided into two or more chambers in this way, they have some great advantages and advantages, but the biggest drawback is that the two chambers communicate with each other in a gas flow manner. In some cases, the stored body fluid may move to a chamber having a suction source. In addition, when the stored body fluid is discharged, the bottle is often turned upside down, and at that time, the body fluid flows into a place communicating with the gas flow and migrates. In this case, the transferred body fluid may cause an infection source such as hepatitis and AIDS for a person who manually operates the suction source, and may impair the suction function depending on the situation. In addition, the amount of stored fluid may not be accurately grasped due to the transfer of body fluid.

[0005]

SUMMARY OF THE INVENTION The present invention makes use of the function of the above-mentioned conventional product, and connects the first chamber for aspirating and storing body fluid from the human wound to the second chamber serving as a suction source in gas flow communication. It prevents the body fluid from migrating through the part where it is present, and the drainage volume can be read directly with high accuracy without consciously paying attention to the prevention of migration, and it is hygienic and easy to operate, especially when it is portable. A further object is to provide a body fluid suction and collector.

That is, the present invention is a tool for suctioning and collecting body fluid (drainage) such as drained blood from an incision wound or a surgical wound, and a suction tool is provided on an upper part of a container body. A suction port for connecting to the means, a drain port having an opening / closing means for introducing drainage into the reservoir, and an outlet having a cap for removing the collected drainage, A valve body, in which a one-way valve provided on the suction side and a core valve that seals by contact with the one-way valve and a flange-shaped valve that tightly seals inside the suction port are integrated into the suction port, is inserted and held in the holding portion. The body fluid suction and collector is characterized in that an opening / closing unit is provided.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram showing a structure of a body fluid suction and collector according to an embodiment of the present invention and a process of suctioning and collecting body fluid.

In the body fluid suction collector according to the present invention, a suction port (2) for connecting to a suction means is provided at the upper part of the container body (1), and an opening / closing means (3) for introducing drainage into a reservoir. A drainage port (4) and a discharge port (6) having a cap (5) for removing the collected drainage liquid are provided, and the suction port (2) has one end on the suction side. The valve (8) is a core valve (9) whose head can be sealed by contact with the one-way valve (8) on the container body (1) side, and the lower part can be tightly sealed inside the suction port (7). Flange valve (1
0), and the opening / closing unit inserted and held in the holding portion (12) is provided.

The container body (1) is not particularly limited in shape such as cylindrical shape, cubic shape and spherical shape, but it is desirable to finish it compact so that it can be easily used for carrying. Further, as the material thereof, hard plastic, glass, etc. are used, but in order to confirm the property, amount, condition, etc. of the collected drainage liquid, it is desirable that it is transparent or at least translucent, such as mobile walking. It is necessary to use a lightweight material that has a toughness that does not easily break during use, and for example, a hard PVC resin or the like is suitable.

One-way valve (8) provided at the suction port (2)
The shape is not particularly limited, but the material is preferably a rubber-like substance or soft plastic having the flexibility to open and close. The core valve (9) capable of contacting and sealing with the one-way valve (8) is slightly harder than the one-way valve (8) in order to fit well with the one-way valve (8) and improve the sealing performance. Is preferred. In addition, the lower flanged valve (1
0) has such a shape and structure that the peripheral portion can contact and seal with the inside (7) of the suction port, and it is also appropriate to use a rubber-like substance or soft plastic if necessary.

Next, a method of using the body fluid suction collector according to the present invention will be described. First, the other end of the drainage tube connected to the drainage port (4) is left in the human wound, the outlet (6) is sealed with a cap (5), and the connection tube (14) is attached to the suction port (2). It is connected to the suction means P via. When suction is started, first, the opening / closing means (3) is opened to suck the drained liquid from the human wound and flow into the liquid collector.
As shown in (a), it is stored in the container body (1). The amount of liquid collected can be easily read by marking the wall surface of the container.

In order to discard the stored drainage, the suction is stopped, the opening / closing means (3) is closed, the cap (5) is removed and the outlet (6) is opened to drain the drainage. By the above procedure, repeated suction and liquid collection can be performed.

Regarding the operation of the opening / closing unit provided at the suction port (2), basically, there are three functions.
Firstly, when the container body (1) is moved (carried), it is possible to prevent the splash due to the ripples of the stored waste liquid from jumping into the inlet of the suction port (2). Secondly, as shown in FIG. 1 (b), when the stored drainage liquid is almost full, the liquid level pushes up the flanged valve (10) to bring it into close contact with the suction port inner side (7),
Prevent drainage from entering the suction port. Thirdly, the flange-shaped valve (10) is inside the suction port (7) when it is accidentally turned upside down when carrying or when draining the drainage liquid when it is discharged near the upside down.
The core valve (9) comes into contact with the one-way valve (8) to close and seal the valve. The drainage thus stored is prevented from moving to the suction means P.

Although the kind of the suction means P is not particularly limited, in addition to a suction pipe, a suction pump, etc. in a hospital, an elastic contractible container is compressed in advance to reduce the internal volume and recover the elasticity of the container. A suction device that uses power to generate negative pressure,
As shown in FIG. 3, a rigid container (16) is provided with an elastic member (17) (balloon or the like) that can expand and contract freely, and a rigid container (1) is formed by using rubber balls (18) having one-way valves at both upper and lower ends.
It is also possible to use a suction tool (15) or the like that evacuates the inside of 6) to expand the elastic member (17) and generate a suction force by the contraction. From the viewpoint of convenience in carrying and handling, it is preferable to use a suction tool like the latter two.

[0015]

EFFECTS OF THE INVENTION When the body fluid suction collector of the present invention is used, the drainage is stored in the bag-shaped material housed in the container. Therefore, the container should be turned upside down when moving or draining the drainage. However, there is no risk of drainage flowing out to the suction source, and the amount of collected liquid can always be measured accurately and easily during use, especially when used in combination with a small suction tool. It is convenient for
It is a body fluid suction collector that can promote healing, is easy to manage, and is easy to handle.
