Description

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 integrator known up to now has 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. The one that generates negative pressure in the container, the elastic member (balloon, etc.) that can expand and contract freely is built in the rigid container, and by expanding this elastic member, the inside of the rigid container is exhausted, and the elastic member contracts. A negative pressure is generated in the container. 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, and it is necessary to perform suction operation such as recompression or reexpansion several times during this period, 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 sucking and storing the exuded portion (body fluid) from the human wound and a second chamber for generating a suction force by the contracting force of a balloon member which 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 pneumonia or 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.

They are connected via a switching mechanism (8) for opening / closing and switching the respective passages of the drainage port-reservoir section and the reservoir section-takeout port.

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. The material used is hard plastic, glass, etc., but it is transparent or at least semi-transparent in order to confirm the properties and amount of the collected drainage, the condition of the partition member (2), etc. Is desirable, and it is necessary to use a lightweight material that has a toughness that does not easily break during use such as when carrying a mobile phone.
It is suitable to use C resin or the like.

The partition member (2) that expands and contracts is not particularly limited, but it is a structure that can smoothly expand and contract with a bellows-like or rubber elastic material and can cope with suction and inflow of drainage, and drainage.
The suction port (4) communicates with the inner cavity of the partition member (2).
Further, the drainage port (6) and the outlet (7) are provided with a switching mechanism (8).
Although it is possible to switch the introduction and the extraction of the drainage at appropriate times, it does not matter if the drainage opening (6) and the drainage opening (7) are opened and closed separately. A method that is easy to handle may be selected as appropriate.

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, a retractable container having elasticity is compressed in advance to reduce the internal volume, and the elasticity of the container is recovered. A suction device that uses power to generate negative pressure,
As shown in FIG. 3, a rigid container (10) is provided with a flexible elastic member (11) (balloon or the like) which is freely expandable and contractible, and a rigid container (1) is formed by using rubber balls (12) having one-way valves at both upper and lower ends.
It is also possible to use a suction tool (9) or the like that evacuates the inside of 0) to expand the elastic member (11) 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.
