The pressure adjusting knob 22 is a cylindrical body rotatably mounted to the front surface of the housing 25. By turning the pressure adjusting knob 22, the pressure for sucking the waste liquid can be set to a predetermined negative pressure (-5, -10, -20, -30, -40, -50, -60 kPa). The pressure regulator main body 21 regulates the pressure of the sucked waste liquid to a predetermined negative pressure according to the setting of the pressure regulating knob 22. The switch lever 26 switches the suction ON and OFF (ON-OFF). The negative pressure (-5, -10, -20, -30, -40, -50, -60 kPa) for sucking the waste liquid is not limited to these negative pressures, and may be any set value.
In addition, the positions of the pressure adjusting knob 22, the switch lever 26, and the air discharge hose 6 are not limited as long as there is no obstruction when the aspirator 1 is used. The piping panel 11 is not limited to being provided on the wall surface of the ward, and may be provided on the wall surface of an operating room, for example, and the aspirator 1 is not limited to being mounted on the piping panel 11 but may be mounted on a support bracket (not shown).
The tank 3 is mounted below the pressure regulator 2. The tank 3 is a cylindrical body having an elliptical horizontal cross section and extending in the up-down direction, and has an elliptical long diameter in the direction perpendicular to the wall surface. The front side of the horizontal cross section of the tank 3 has a shorter minor diameter than the rear side. The short diameter of the front side is about 6.5cm, which is a size that can be easily grasped by a small person.
Further, the tank 3 includes: a tank body 51 in which a housing bag 5 is detachably housed in a horizontal direction, the housing bag 5 separating and housing the sucked waste liquid and the gas sucked together with the waste liquid; and a cover 52A provided in an opening 60 opened in the right side surface of the can 3, and openable and closable in the horizontal direction. The lid 52A is attached to the can 51 by a hinge, and is opened and closed in the horizontal direction. When the lid 52A is opened, the storage bag 5 stored in the can 3 can be taken out in the horizontal direction.
The can body 51 has a can mount 58, a ball plug 59, and a can exhaust member 53 provided on an upper surface of the can body 51. The ball plug 59 is composed of a tool coil spring 71 and a ball 72, the tool coil spring 71 is attached to the upper surface of the can body 51, and the ball 72 is rotatably attached to the upper end of the tool coil spring 71. On the other hand, the tank exhaust member 53 is hermetically connected to the connection port 24.
When the tank 3 is detached from the pressure regulator 2, the tool coil spring 71 of the ball plunger 59 is compressed and the ball 72 at the upper end is pressed down when the tank 3 is pulled in the forward direction (the direction opposite to the wall surface), and the tank 3 can be easily detached. In addition, the tank 3 can be detached in a state where the pressure regulator 2 is attached to the attachment 4, and the operation of attaching and detaching the tank 3 is not complicated. The tool coil spring 71 may be a plate spring, for example, as long as the ball 72 at the upper end of the tool coil spring 71 of the ball plunger 59 is biased to press the bottom surface of the housing 25, and is not limited to the tool coil spring 71.
In addition, when the tank 3 is assembled to the pressure regulator 2, the tank attachment 58 is inserted into the tank receiver 28 provided at the lower portion of the pressure regulator 2 by holding the tank 3 by hand, and when the tank attachment 58 is detached, it is necessary to pull out the tank attachment 28 from the tank receiver 28. Since the concave portion 56 recessed inward is provided in the upper portion of the outer side surface of each of the tank body 51 and the lid portion 52A, the tank 3 can be reliably held and attached by one hand when the concave portion 56 is held by a finger when the tank 3 is held by the hand.
The lid 52A closes the opening 60 on the left side surface of the tank body 51, thereby hermetically maintaining the negative pressure inside the tank 3. Since the interior of the can 3 is negative pressure, the can body 51 and the lid 52A may be rigid bodies having strength not to be deformed by the negative pressure, for example, resin. The lid 52A is provided with a pressure release hole 61 penetrating the lid 52A to release the negative pressure in the tank 3.
The can body 51 and the lid 52A have transparent or semi-transparent window members 55 at a part thereof, and the state of the storage bag 5 inside the can 3 can be visually checked from the window members 55. The can body 51 may be transparent or translucent as a whole. The cover 52A may be transparent or translucent as a whole. On the other hand, from the viewpoint of maintaining air tightness and reducing the number of parts, the respective window members 55 and portions other than the window members 55 of the tank body 51 and the lid 52A are preferably integrally molded.
The storage bag 5 is composed of a bag body 81 and a spout 82, wherein the bag body 81 contains a coagulant (not shown) for coagulating the waste liquid sucked together with air, and the spout 82 is hermetically joined to the upper portion of the bag body 81. The pipe portion 82 has: a nozzle 83, the nozzle 83 being connected to a suction hose (not shown) for sucking the waste liquid; and a bag body exhaust port 84, the bag body exhaust port 84 exhausting gas from the inside of the bag body 81. A hydrophobic filter (not shown) is disposed at the bag outlet 84. The hydrophobic filter (not shown) separates the waste liquid from the gas and prevents the waste liquid from flowing out of the storage bag 5, thereby allowing only the gas to be discharged from the tank 3.
A nozzle through hole 54 through which the nozzle 83 passes is provided at a position where the tank body 51 contacts the lid 52A in the upper part of the front surface of the tank 3, and a pressure release mechanism 101 for locking the lid 52A to the tank body 51 in an airtight manner is provided at a position approximately in the center where the tank body 51 contacts the lid 52A in the tank 3. A protruding positioning guide 57 is provided on the outer surface of the tank body 51 at a position close to the nozzle through hole 54. The positioning guide 57 is located at a position corresponding to the flange recess 86 of the flange 85 provided to the nozzle 83 to ensure the airtight seal of the inside of the can 3. By fitting the flange concave portion 86 into the positioning guide 57, the nozzle 83 is guided to a predetermined position, and the storage position of the storage bag 5 is determined, so that the airtight state of the inside of the can 3 is reliably maintained.
Fig. 7 is an enlarged cross-sectional view of the bottom of the tank 3 of the aspirator 1 according to the embodiment of the present invention according to the portion a' of fig. 5. The tank body 51 has a waste liquid reservoir 91 at the bottom thereof, and the central portion of the waste liquid reservoir 91 is recessed to store waste liquid. Even when the waste liquid leaks out of the tank 3, the waste liquid is stored in the waste liquid reservoir 91, and the waste liquid can be prevented from leaking out of the tank 3.
Fig. 4 (a) is a right side view showing a state where the pressure release mechanism 101 of the aspirator 1 according to the embodiment of the present invention is closed, and fig. 4 (B) is a right side view showing a state where the pressure release mechanism 101 of the aspirator 1 according to the embodiment of the present invention is open. Fig. 8 is an enlarged sectional view of the pressure release mechanism 101 in a closed state, as viewed in the direction of arrow E-E in fig. 4 (a), that is, as viewed from the bottom surface of the tank 3 upward, and fig. 9 is an enlarged sectional view of the pressure release mechanism 101 in an open state, as viewed in the direction of arrow F-F in fig. 4 (B).
The pressure release mechanism 101 has a lever 103 that rotates about a fulcrum 102 and an urging member 104. The fulcrum 102 is located at a substantially central portion in the longitudinal direction of the lever 103, and the lever 103 is rotatably attached to the cover 52A at the fulcrum 102.
A force application member 104 is disposed at one end 111 of the lever 103. The urging member 104 urges and presses the one end 111 of the lever 103 in the outward direction. The urging member 104 may be a tool coil spring or a leaf spring, for example, as long as it can urge the lever 103.
The other end 112 of the lever 103 has: a seal 107, the seal 107 pressure-tightly sealing a pressure release hole 61 provided in the tank body 51; and a protrusion 113, wherein the protrusion 113 is provided at the other end 112 and is fitted into the lever receiving portion 62 provided in the cover 52A. The seal 107 is biased by the biasing member 104 to be pressed against the pressure release hole 61, thereby sealing the pressure release hole 61 to hermetically maintain the negative pressure inside the tank 3. Further, if the seal 107 is an elastic body, for example, natural rubber, silicone rubber, or the like, the pressure release hole 61 can be reliably sealed to hermetically hold the inside of the tank 3, which is preferable.
Next, a method of using the aspirator 1 according to the embodiment will be described.
First, preparation for sucking and removing the waste liquid will be described. The storage bag 5 is stored in the can 4 and the lid 52A is closed. Then, the tank 3 is mounted to the pressure regulator 2 by inserting the tank mount 58 toward the wall surface into the tank receiver 28 on the lower surface of the housing 25 to be fitted with the tank receiver 28. When the can body attachment 58 is fitted into the can body receiver 28 on the lower surface of the housing 25, the ball 72 on the upper end of the ball plug 59 is biased by the tool coil spring 71 disposed below the ball 72 and pressed against the lower surface of the housing 25, and the housing 25 and the ceiling column 51 are assembled in an airtight manner.
Next, the aspirator 1 is attached to the pipe panel 11 on the wall surface via the attachment 4, and the exhaust hose 6 is connected to a suction port (not shown) of the pipe panel 11. Then, a suction hose (not shown) is attached to the nozzle 83 of the storage bag 5 protruding from the front surface of the tank 3.
Then, a predetermined suction pressure is set by the pressure adjusting knob 22. Next, the switch lever 26 is set to the on position, and suction is started. Thus, the air in the tank 3 is discharged from the suction port (not shown) of the piping panel 11 through the tank air discharge member 53, the connection port 24, the pressure regulator main body 21, the air discharge port 23, and the air discharge hose 6, and the inside of the tank 3 is brought to a negative pressure. The air in the storage bag 5 is also discharged from the bag body exhaust port 84, and the inside of the storage bag 5 is also negative pressure.
In addition to the preparation for the suction and removal of the waste liquid, the tip of a suction hose (not shown) connected to the nozzle 83 is placed at a desired position, and suction and removal of the waste liquid from the patient is started. The sucked waste liquid is sucked together with air into the storage bag 5 through a suction hose (not shown) and the nozzle 83. Since the hydrophobic filter (not shown) disposed at the bag body air outlet 84 does not pass the waste liquid, the sucked waste liquid is stored in the storage bag 5. The waste liquid separated from the air reacts with the coagulant in the accommodating bag 5 and solidifies. On the other hand, the air passes through the hydrophobic filter (not shown) and is discharged by a suction pump (not shown) through the bag outlet 84, the tank outlet 53, the connection port 24, the pressure regulator main body 21, the outlet 23, the air discharge hose 6, and the suction port (not shown) of the piping panel 11. In addition, a hydrophobic filter (not shown) disposed at the bag body air outlet 84 prevents the liquid of the waste liquid from passing through the filter, and prevents the waste liquid from flowing out of the storage bag 5 and flowing into the suction pump (not shown) through the pressure regulator main body 21.
When a constant amount of waste liquid is sucked and a constant amount of waste liquid is stored in the storage bag 5, the suction is stopped and the storage bag 5 is replaced by setting the switch lever 26 to the off position.
Here, in a state where the pressure release mechanism 101 is closed, the lever 103 is biased by the biasing member 104, the projection 113 is fitted into the lever receiving portion 62 provided in the cover portion 52A, and the cover portion 52A is fixed without being opened. Further, the other end 112 presses the seal 112 against the pressure release hole 61 provided in the lid portion 52A to seal the inside of the can 3 in an airtight manner.
When the lid 52A is opened to remove the storage bag 5 from the can 3, if a force is applied to press the one end 111 of the lever 103, the lever 103 rotates counterclockwise on the drawing of fig. 8 about the fulcrum 102, and the seal 107 is separated from the pressure release hole 61 in accordance with the rotation of the lever 103. By separating the seal 107 from the relief hole 61, the relief hole 61 is opened (refer to fig. 9). By opening the pressure release hole 61, air is caused to flow into the interior of the tank 3 through the pressure release hole 61 to bring the interior of the tank 3 to the atmospheric pressure. On the other hand, the protruding portion 113 is disengaged from the lever receiving portion 62, and the lid portion 52A can be opened. The lid 52A is opened in the horizontal direction, the nozzle 83 of the storage bag 5 is detached from the nozzle through hole 54, and the storage bag 5 is removed in the horizontal direction, and then the storage bag 5 is discarded.
Then, the flange recess 86 of the flange 85 provided on the nozzle 83 of the new storage bag 5 is fitted in correspondence with the positioning guide 54 of the nozzle through hole 54, and the storage bag 5 is stored in the tank 3. Then, when the lid 52A is closed and the one end 111 of the lever 103 is released, the lever 103 is urged by the urging member 104 so that the one end 111 of the lever 103 is pushed back in the outward direction, and thereby the lever 103 rotates counterclockwise in the drawing of fig. 6 about the fulcrum 102, that is, the one end 111 of the lever 103 rotates in the outward direction (positive direction). The lever 103 is biased by the biasing member 104, so that the protrusion 113 is pressed to fit into the lever receiving portion 62 provided in the cover 52A, and the cover 52A is fixed without being opened (see fig. 8).
In addition, in the case where the tank 3 is contaminated, the tank 3 can be detached from the pressure regulator 2, and the tank 3 can be cleaned using a cleaner. When the tank 3 is pulled in the proximal-forward direction, the ball 72 at the upper end of the ball plunger 59 is pushed downward, and the tank mount 58 is disengaged from the tank receiver 28 at the lower surface of the housing 25, so that the tank 3 can be detached from the pressure regulator 2.
Next, a second embodiment of the present invention will be described.
