The present application claims priority from Japanese patent application No. 2018-211650, filed in Japan on 11/9/2018, and the contents thereof are incorporated herein.
Background
In order to suck and discharge body fluid (also referred to as drainage fluid) such as blood or exudate from a wound of a human body through a tube, a medical suction instrument is generally used which includes a storage container for storing the drainage fluid and a negative pressure container connected to the storage container and generating negative pressure for sucking the drainage fluid.
For example, patent document 1 discloses a medical suction instrument (described as a liquid discharge suction device in the document) including: a storage container (described as a liquid discharge container in this document) that stores liquid discharge; and a negative pressure container (described as a water seal in the document) that is connected to the storage container and the suction regulator, and that can check a negative pressure state while making the interior of the storage container negative in pressure.
The negative pressure container described in this document is connected to the storage container through a pipe. Water to be immersed in the tip end portion of the duct is contained in the negative pressure container, and air in the container is sucked through the duct by the negative pressure generated in the negative pressure container by the suction regulator. By this suction, a predetermined negative pressure corresponding to the internal pressure of the body cavity of the patient is generated in the storage container. The suction force generated in the storage container is monitored as the generation of bubbles released from the tip of the pipe into the water-sealing liquid (water) in the negative pressure container.

Detailed Description
Hereinafter, embodiments of the medical suction apparatus according to the present invention will be described with reference to the drawings.
The embodiments described below are merely examples for facilitating understanding of the present invention, and do not limit the present invention. That is, the shape, size, arrangement, and the like of the components described below can be modified or improved without departing from the gist of the present invention, and it is needless to say that the present invention includes equivalents thereof.
In all the drawings, the same constituent elements are denoted by the same reference numerals, and redundant description is omitted as appropriate. Hereinafter, the "vertical direction" refers to a vertical direction in a state where the medical suction apparatus 1 is set upright as shown in fig. 1.
< summary >
First, an outline of the medical suction apparatus 1 according to the present embodiment will be described mainly with reference to fig. 1 and 2. Fig. 1 is a perspective view showing a medical suction device 1 according to the present embodiment, and fig. 2 is a bottom view of a bottle cap 9.
The medical suction device 1 according to the present embodiment sucks and discharges liquid by the negative pressure generated in the negative pressure container 2. The medical suction device 1 includes: a negative pressure container 2; an air discharge unit (air discharge member 4) connected to the negative pressure container 2 and discharging air to the outside; and a storage container 3 connected to the negative pressure container 2 and having a storage section 3e for storing the discharged liquid.
A filter 10 is provided in a path of air from the inside of the storage container 3 to the inside of the negative pressure container 2, and the filter 10 prevents the passage of liquid and solid and allows the passage of air.
Since the filter 10 is provided on the path of the air from the inside of the container 3 to the inside of the negative pressure container 2, even when the container 3 is accidentally pushed down and brought into a state (collapsed state) different from the normal use state (standing state), the discharged liquid contained in the container 3 can be prevented from moving to the negative pressure container 2.
By suppressing the movement of the discharged liquid from the storage container 3 to the negative pressure container 2 in this manner, for example, the bag 5 can be prevented from being deteriorated by contact with the discharged liquid when the bag 5 is set in the negative pressure container 2, and the negative pressure container 2 can be kept clean. Further, the discharged liquid can be prevented from further leaking (jetting) to the outside via the negative pressure container 2.
< Structure of each part >
Next, the structure of each part of the medical suction apparatus 1 will be described with reference to fig. 3, in addition to fig. 1 and 2. Fig. 3 is a view showing a cross section around the bottle cap 9, and is a view showing a cross section III-III of fig. 2.
The negative pressure tank 2 is provided with a bladder 5 for confirming a pressure state or the like. A cap 2a that allows air in the negative pressure container 2 to communicate with the outside and allows air to be drawn out is attached to a lower portion of the negative pressure container 2. The capsule 5 is disposed inside the negative pressure container 2 via the cover 2 a.
The negative pressure container 2 and the storage container 3 are connected to each other through a connecting pipe 6.
The storage container 3 includes: a container body 3d having a housing portion 3 e; and a connection cap (bottle cap 9) that covers the opening of the container body 3d and has a connection portion (connection boss (boss)9a) for connecting to the negative pressure container 2 via the connection pipe 6.
As shown in fig. 1, the cap 9 has a liquid collection port 9b projecting upward. The storage container 3 is configured such that a tube, not shown, is connected to the liquid collection port 9b and the discharged liquid can be stored in the storage container 3. The clamp member 3b is attached to the liquid collection port 9b, and the flow path connected to the liquid collection port 9b is closed by the clamp member 3b, whereby the inflow of the liquid discharged from the human body into the storage container 3 is prevented.
A filter mounting portion 9d to which the filter 10 is mounted is provided in the storage container 3 (on the container body 3d side of the cap 9). The filter mounting portion 9d has a stepped portion to which the peripheral edge of the disc-shaped filter 10 is joined (or welded), is formed in a circular shape in a plan view, and is formed to protrude downward from the periphery.
As shown in fig. 3, a return projection 9e is formed on the surface of the cap 9 on the side of the housing portion 3e so as to protrude toward the housing portion 3e (toward the filter 10) at the periphery of the connection boss 9 a. The return projection 9e is used to suppress the inflow of the waste liquid into the connecting pipe 6 when the container 3 is pushed down and the waste liquid flows into the connecting pipe 6 side through a vent hole 10a described later than the filter 10. The return projection 9e is formed to have a circular (annular) cross section and to protrude from the periphery of the through hole penetrating the connection boss 9a toward the housing portion 3 e.
The use of the return projection 9e allows air to flow between the connection boss 9a and the vent hole 10a, and also suppresses the liquid discharged from the vent hole 10a from flowing through the connecting pipe 6.
A cylindrical inner boss 9c connected to the liquid trap port 9b is formed on the surface of the cap 9 on the side of the storage section 3e so as to protrude toward (below) the storage section 3 e.
The air discharge member 4 is for discharging air in the medical suction device 1 (negative pressure container 2) to the outside to bring the inside of the negative pressure container 2 into a negative pressure state, and includes an air discharge portion-side check valve 7 and a negative pressure container-side check valve (not shown) on the negative pressure container side and the air discharge port side. The exhaust member 4 is configured to have elasticity and be deformable between a natural state and a pressed state in which the exhaust member is pressed from the natural state.
< about Filter >
The filter 10 is attached to the filter attachment portion 9d and disposed on the container body 3d side of the bottle cap 9.
Since the filter 10 is attached to the cap 9, the filter 10 can be easily disposed in the storage container 3 by attaching the cap 9 to the container body 3 d. The filter 10 disposed in the storage container 3 is disposed so as to separate an internal space of the connecting pipe 6 and an internal space of the storage container 3, and the connecting pipe 6 connects the negative pressure container 2 and the storage container 3.
The filter according to the present invention is not limited to the filter 10 attached to the cap 9 as long as it is disposed on the path of air from the inside of the storage container 3 to the inside of the negative pressure container 2.
For example, the filter may be provided inside the connecting pipe 6, or may be provided inside a joint, not shown, which is provided between the connecting pipe 6 and the joint when the connecting pipe is divided to connect the divided members.
Further, in the case where the cap 9 is not provided, the filter may be attached to the container body 3d, or may be disposed in the negative pressure container 2 at a position that separates the connecting pipe 6 from the internal space of the negative pressure container 2.
A vent hole 10a having a diameter larger than the average pore size of the filter 10 is formed in the filter 10. The "average pore diameter of the filter 10" specifically means an average pore diameter of a plurality of pores provided in a porous material 10d described later, and is a value calculated by, for example, mercury intrusion measurement using a test piece obtained by cutting out a portion of the filter 10 where the vent hole 10a is not formed.
The filter 10 does not necessarily have to be formed with the ventilation holes 10 a. However, by forming the vent hole 10a in the filter 10, it is easy to avoid complete loss of the air permeability when a part of the filter 10 is clogged with the discharged liquid, and it is easy to continue the subsequent liquid discharging operation.
In the upright state of the housing container 3 shown in fig. 1, the vent hole 10a of the filter 10 is formed on a virtual line L passing through the center of the housing portion 3e and extending in the upward direction.
The "standing state of the storage container 3" includes, in addition to the state of automatic standing, for example, a state in which a part of the storage container 3 is suspended from a part of a shelf next to a bed and the bottom surface floats, and the state is in the same posture as the state of automatic standing.
By forming the vent hole 10a on the imaginary line L extending upward through the center of the housing portion 3e of the housing container 3 in this manner, it is possible to make it difficult for the discharged liquid to reach the vent hole 10a regardless of which direction the housing container 3 is pushed down.
That is, if the liquid is stored only from half of the storage container 3 to a height lower than the radius of the vent hole 10a, the liquid does not leak from the vent hole 10a even if the storage container 3 is pushed down and left as it is. Therefore, the liquid discharged from the storage container 3 can be prevented from flowing into the negative pressure container 2 through the connecting pipe 6 after passing through the vent hole 10 a.
In the present embodiment, the vent hole 10a is provided at the center of the circular filter 10 and is disposed on the virtual line L, but the present invention is not limited to such a configuration. That is, the vent hole 10a may be disposed on the imaginary line L even if it is disposed at a corner of the filter 10, not at the center of the filter 10.
The filter 10 is formed with a through hole 10b, and the through hole 10b is formed with a diameter equal to or slightly larger than the outer diameter of the inner boss 9c for allowing the inner boss 9c provided in the cap 9 to pass therethrough. The inner boss 9c and the through hole 10b through which the inner boss 9c passes can prevent the liquid discharged from the liquid collection port 9b from contacting the filter 10 in a normal state (standing state), and the liquid can be collected in the housing portion 3 e.
< materials for construction of Filter >
Next, the constituent materials of the filter 10 will be described mainly with reference to fig. 4. Fig. 4 is an enlarged cross-sectional view showing an enlarged cross-section of the filter 10 according to the present embodiment.
The filter 10 is a sheet-like filter including a nonwoven fabric 10c and having a hydrophobic property at least on the surface on the housing portion 3e side.
Specifically, the filter 10 according to the present embodiment includes, as a membrane, an open-cell type (open-cell type) resin porous material 10d containing an acrylic copolymer, and includes, as a support material, a nylon nonwoven fabric 10 c. In the filter 10 according to the present embodiment, the porous material 10d is positioned on both sides or inside the nonwoven fabric 10c and is not clearly separated as a layer, and there is no distinction between the front and back surfaces in the filter 10. The porous material 10d is a hydrophobic member, and whether or not the nonwoven fabric 10c is hydrophobic is arbitrary.
In this way, since the filter 10 is a sheet-like filter including the nonwoven fabric 10c and having the hydrophobic property at least on the surface on the housing portion 3e side, it is possible to prevent the liquid and the solid from passing therethrough and to stabilize the shape of the filter 10 in accordance with the characteristics of the nonwoven fabric 10c as the support material.
The filter 10 has been described as a filter having "hydrophobic property", but strictly speaking, it means "the entire surface on the housing portion 3e side has hydrophobic property", and may include a filter having hydrophilic property in a part other than the surface on the housing portion 3e side.
In particular, the porous material 10d of the filter 10 is preferably provided so as to face (be exposed) to the housing 3 e.
In this way, since the filter 10 includes the open-pore porous material 10d (for example, a resin film) made of resin facing the housing portion 3e, the discharged liquid can be appropriately captured while passing the air from the housing portion 3e through the porous material 10d, and the discharged liquid housed in the housing portion 3e can be appropriately prevented from being directed toward the negative pressure container 2.
The porous material 10d is impregnated into the gaps between the fibers constituting the nonwoven fabric 10c and bonded to the nonwoven fabric 10 c. Since the porous material 10d is impregnated into the nonwoven fabric 10c and bonded to the nonwoven fabric, the bonding force between the porous material 10d and the nonwoven fabric 10c is improved.
As described above, the porous material 10d is preferably provided on the housing portion 3e side, but is not limited to such a configuration. That is, which surface of the filter 10 is attached to the filter attachment portion 9d can be arbitrarily selected.
(modification)
Next, the constituent materials of the filter 10X according to the modification will be described mainly with reference to fig. 5. Fig. 5 is an enlarged cross-sectional view showing an enlarged cross-section of a filter 10X according to a modification.
The filter 10X according to the modification includes an open-cell type resin porous material 10f containing polyallyl sulfone (PAS) as a film, and a polyester nonwoven fabric 10e as a support material.
The filter 10X is configured to include: a 1 st layer 10g including a nonwoven fabric 10e and a 2 nd layer 10h different from the 1 st layer 10 g. The 1 st layer 10g is disposed on the filter mounting portion 9d side of the center of the filter 10X in the thickness direction. More specifically, the 1 st layer 10g is disposed so as to be exposed to the surface on the filter mounting portion 9d side.
In this way, since the 1 st layer 10g including the nonwoven fabric 10e is disposed on the filter mounting portion 9d side of the center in the thickness direction of the filter 10X, the shape of the filter 10X on the filter mounting portion 9d side can be stabilized by the 1 st layer 10 g. In other words, since the shape of the nonwoven fabric 10e portion of the 1 st layer 10g can be suppressed from changing, the filter 10X can be suppressed from being peeled off from the filter mounting portion 9 d.
Further, the 2 nd layer 10h containing a large amount of the porous material 10f can be widely secured in the thickness direction of the filter 10X, and the 2 nd layer 10h is a region where more discharged liquid is captured than the 1 st layer 10 g.
The filter 10X is not limited to a filter in which the 2 nd layer 10h does not contain the nonwoven fabric 10e at all. That is, even if the 1 st layer 10g and the 2 nd layer 10h are respectively composed of the porous material 10d and the nonwoven fabric 10e, the proportion of the nonwoven fabric 10e contained in the 1 st layer 10g may be higher than the proportion of the nonwoven fabric 10e contained in the 2 nd layer 10 h.
As described above, the 1 st layer 10g is preferably disposed on the filter attachment portion 9d side, but is not limited to such a configuration. That is, which surface of the filter 10X is attached to the filter attachment portion 9d can be arbitrarily selected.
