DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical suction / discharge device for discharging a liquid and a gas from a body cavity such as a chest after an operation mainly in a surgical treatment.

[0002]

2. Description of the Related Art Medical suction and discharge devices are often used to maintain a constant internal pressure after a thoracotomy, and include a disposable type using a three-bottle method and an instrument with a built-in pump. Type and exists. The disposable type has a most common pressure regulating unit and a liquid collecting container integrally formed, and a separate pressure regulating unit as disclosed in JP-A-60-5162. There are containers that are used by connecting the containers and the containers can be exchanged.
The instrument type is such that the pressure adjusting section is constituted by an instrument pump, and the container is of the same form as in JP-A-60-5162.

[0003] The following advantages are recognized in the form in which the pressure regulating section and the container are separated and the container can be replaced. (1) Since only the container can be replaced, a small capacity of 500 cc or less for a child, a capacity of 1000 cc or more for an adult, or a capacity of about 100 cc to 500 cc for an adult can be handled depending on the purpose of treatment. (2) It is economical because only the container can be disposable. (3) Since the container is composed of a liquid collection chamber and a water sealing chamber,
Even if the container is separated from the pressure regulator, the collection chamber is through the water seal chamber, so there is no direct communication with the atmospheric pressure, providing excellent safety, especially as a natural drainage that does not apply suction to patients with mild pneumothorax etc. It is also possible to use.

In a mode in which the pressure regulating section and the container are separated and the container is replaceable, the container is often handled by hand at the time of the water injection operation of the water sealing and the discharge operation of the drainage liquid. Because the rooms are arranged with little space in the order of the room, the transition prevention room, the capillary tube and the water seal room, there is no part that can be held firmly by hand, and for nurses whose hands are relatively small and their grip strength is not large. It was difficult to hold, and it was difficult to perform operations such as water injection and drainage. Although rare in such cases, the container may be accidentally dropped and the drainage may splatter on the floor, putting the working nurse and surrounding patients at risk of hospital-acquired infection. there were.

DISCLOSURE OF THE INVENTION The present invention has been made as a result of studying to solve such a problem of the conventional medical suction / discharge device container, and is easy to hold, excellent in workability, and accidentally dropped. It is an object of the present invention to provide a container for a medical suction / discharge device which is less likely to be caused.

[0006]

That is, the present invention provides a connection port,
A transition prevention chamber, a container at least composed of a liquid collection chamber and a water sealing chamber, apart from a section having no lumen for separating each chamber, a section having no lumen wider than the section or A container for a medical suction / discharge device, characterized in that a portion having a lumen having a small depth is provided.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. 1 to 3 are schematic views showing one embodiment of a container for a medical suction / discharge device according to the present invention, and FIG. 4 shows an example of a conventional container for a medical suction / discharge device. Generally, as shown in FIG. 4, the container is composed of a collection chamber (5) composed of two or more chambers and sterile water used as a water seal when a super negative pressure occurs to the collection chamber (5). Transition prevention chamber (6) for preventing migration, vertically arranged thin tubes (4)
And a water sealing chamber (3), and a connection port (7b) for connecting a drain tube from a patient at the upper part of the liquid collection chamber (5).
However, a connection port (7a) for connecting a pressure regulator for adjusting the suction pressure is provided at the upper part of the water sealing chamber (3), and the rooms are usually arranged without gaps. In such a case, since there is no portion into which a finger can enter when holding the bottle, it is difficult to hold the container as described above, resulting in poor workability.

Therefore, as shown in the embodiment of FIGS. 1 to 3 of the present invention, FIG. 1A shows a bush having no lumen between the rooms or FIG. 3B shows a bush having a narrow depth.
b) Or, by providing a space (2) as shown in FIG. 2, a portion is provided for a finger to enter when holding the container by hand. FIG. 1 shows a bushing (1) without a lumen between the water sealing chamber (3) and the capillary (4).
a) is provided so that the water sealing chamber (3) can be gripped so that a finger can enter the squash (1a), and the water sealing chamber (3) plays a role of a handle.

FIG. 2 shows a case in which a space-less portion is provided between the water sealing chamber (3) and the thin tube (4). (3)
Is to be able to hold. This makes it easier to hold than the one provided with the crush (1a), but on the other hand, the stiffness of the whole container is inferior, the problem of burr treatment at the time of molding is considered, and the crush is performed in consideration of strength and manufacturing cost. It is desirable to determine whether to adopt (1a) or space (2).

The crush (1a) or the space (2) without a lumen may be provided between the liquid collecting chambers (5) as shown in FIG. 3, regardless of the position in FIGS. In this position, it is desirable to select a part that provides the best workability in consideration of the treatment of drainage and the operation of injecting sterile water into the water sealing chamber (3). When the drainage collected in the liquid collection chamber (5) is drained, the weight of the container is the largest and it is considered that the container must be firmly held. Alternatively, it is preferably provided in the portion shown in FIG.

[0011]

When the container for a medical suction / discharge device according to the present invention is used, the container is erroneously dropped and the drainage liquid is scattered to the floor by improving the ease of holding the container in the operation of handling the container. This improves the workability of water injection and drainage, and eliminates the risk of hospital infection.
