DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small, portable suction liquid collecting apparatus utilizing negative pressure generated by the contraction force of a balloon member used for removing exudate from a body cavity by suction after an operation or the like. It is about a vessel.

[0002]

2. Description of the Related Art In general, it is known to use a suction collector as a means for removing exudate from a wound cavity of a human body. In this case, a tube for guiding the exudate to be discharged is inserted into the wound cavity and suction is performed. The exudate in the wound cavity is accumulated and stored in the suction liquid collector due to the negative pressure generated in the suction liquid collector, which is connected to the liquid collector. There are various mechanisms for generating a negative pressure in the suction liquid collector. Among them, a rigid container has a built-in inflatable and deflateable balloon member, and almost always utilizes the action of contracting the balloon member. The mechanism is clinically superior in maintaining a constant suction pressure, and this mechanism is roughly classified into two types of diametrically opposite methods of inflating the balloon member.

In the first type, as shown in FIG. 3, the balloon member is inflated by injecting air into the balloon member. When the balloon member is inflated, an operation for opening the outlet is always required. was there. Also, a one-way valve is installed at the connection of the bodily fluid guiding tube in order to prevent the balloon member from inflating by accidentally opening the outlet and positive pressure inside the container to prevent the exudate from flowing back into the wound cavity. Thus, there was a risk that coagulated matter such as fibrin contained in the exudate passing through would adhere to one valve and be blocked.

The second type expands the balloon member by evacuating the air around the balloon member. Since exudate is stored around the balloon member, when the container is turned sideways when carrying the patient. When the pumping operation is performed to cause the stored liquid to flow into the negative pressure generating mechanism and inflate the balloon member again, the stored liquid may be discharged to the outside air and the operator may be infected. There are drawbacks such as connecting the two containers for storing and placing the balloon member, or making the container large and bulky to carry.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and it is a type in which air around a balloon member is exhausted to inflate the balloon member. When carrying, the route to the negative pressure generation mechanism from the inside of the container can be shut off, so that even if the container falls down, there is a danger that the stored liquid will not flow into the negative pressure generation mechanism and the stored liquid will jump out to the outside air, There is no danger of such a re-inflation operation of the balloon member can be performed safely,
Another object of the present invention is to provide a medical suction liquid collector that can be carried by a patient without being bulky because it is a small container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is an external view showing an embodiment of a medical discharge device according to the present invention, and FIG. 2 is a sectional structural view of FIG. As shown in FIG. 1, the medical suction liquid collecting device of the present invention comprises a rigid transparent container (2) having three independent openings (3), (4), and (5) at the top. .

The container (2) is preferably formed of a transparent hard plastic or glass, and an opening (3) provided at one end of the upper portion of the container (2) is provided with a tube connecting device (8) to exude. A liquid guide tube (9) can be connected thereto. An opening (4) provided substantially at the center of the upper part of the container (2) has a balloon (28) built in the container (2) and a balloon (28). A rubber ball (21) provided with one-way valves (22) and (23) at the inlet and outlet for discharging air in the container (2) above the fixed member (24) to be held and the fixed member (24). ), And a switching member (25) for opening and closing a communication path between the inside of the container (2) and the negative pressure generating mechanism (20) is mounted on the fixing member (24). Is attached to the container (2), and an opening ( ) Has a structure that can be opened if necessary.

The shape of the container (2) may be square, cylindrical or water bottle, and it is preferable to make the shape convenient for carrying around a human body. The tube connecting device (8) is a tube-shaped molded product having a communicating lumen and is formed of soft plastic or rubber, and the extrudate guide tube (9) is inserted at the upper end so that the exudate guide tube (9) can be tightly fixed. It is designed to have an inner diameter slightly smaller than the outer diameter of the tube (9). A flange (7) is integrally formed with the tube connecting device (8), and the container (2) is formed.
Is fixed to the opening (3). A clamp (10) is mounted on the upper part of the flange (7), the purpose of which will be described later. The tube connection device (8) described here is an example according to the present invention, and can be appropriately designed to be simple. For example, the guide tube may be inserted linearly with the inner diameter of the container opening matched to the outer diameter of the exudate guide tube (9), and the clamp (10) may be attached to the guide tube (9).

In the opening (4) of the container (2), a balloon (28) is held by a fixing member (24) having an upper portion connected to a negative pressure generating mechanism (20) and is incorporated in the container (2). It is fixed in close contact. The fixing member (24) is provided with two routes, the first of which is a narrow path (30) through which the lumen of the balloon (28) and the atmosphere communicate with each other in a gas flow. At the time of expansion, the atmosphere becomes narrow (3
0) flows into the balloon lumen (29), and when the balloon (28) is deflated, the air in the balloon lumen (29) is discharged to the atmosphere via the narrow path (30). It is important that this air inlet / outlet path always communicates freely with the atmosphere, and no valve mechanism is provided in the middle path.

Further, the inlet of the exhaust path (31) in the container is installed so that the flow can be opened and closed by the switching member (25). The tip of the switching member (25), that is, the seal member (26) for sealing the inlet of the exhaust path (31) is not particularly limited as long as it is made of a material and a material such as rubber which can easily maintain airtightness. Absent.

Further, the switching member (25) includes a container (2)
The seal portion (27) that comes into contact with the container (2) for opening and closing operations from the outside is preferably made of a material that has the same airtightness as described above and also has a slidability by operation. It is also advantageous to apply an agent. The balloon (28) is formed of rubber having a small permanent distortion, and a negative pressure corresponding to the contraction force of the balloon is generated in the lumen of the container (2). The suction force of exudate required in the medical field is generally -1.
It is preferable to select a rubber material having an appropriate elastic modulus which is about 0 to -150 mmHg and generates these suction forces. The opening (5) of the container (2) is for discharging the exudate stored in the container (2) out of the container (2), and is sealed with a lid (32) during use. . Although the configuration of the medical suction / collection device of the present invention has been described above, the purpose of the present invention and a supplementary explanation will be given through the method of use.

As preparation for using the suction liquid collector (1) according to the present invention, first, the tube connecting device (8) is airtightly closed with the clamp (10), and then the switching member (25) is opened, and the rubber is opened. The air in the container lumen (6) is evacuated by pumping the ball (21). As the air is exhausted, the balloon (28) expands according to the pressure difference between the balloon lumen (29) and the vessel lumen (6) under atmospheric pressure as described above,
The switching member (25) is closed when the balloon (28) is almost completely inflated to the container lumen (6). At this point, the container lumen (6) maintains a negative pressure degree by a contraction force corresponding to the elasticity of the balloon (28). In sucking and discharging the exudate in the body cavity, the end of the exudate guide tube (9) placed in the body cavity is strongly inserted into the tube connecting device (8) as shown in FIG. ) To release the tightening. At this time, the suction liquid collector and the inside of the body cavity communicate with each other via the exudate guide tube (9), and the negative pressure applied in the container (2) propagates into the body cavity, and the exudate is transferred to the container (2). Induction discharge into). The stored amount of exudate can be read on the scale (33) displayed on the container (2), and the operation is performed until the balloon (28) is completely deflated as the stored amount increases.
