Description

[Detailed description of the invention] The present invention relates to a device for squeezing a drench tube used when discharging material from a specific place to a predetermined place, and is particularly suitable for squeezing a drench tube for medical use. This invention relates to a drench tube squeezing device for thoroughly discharging waste materials.

Conventionally, with medical drench tubes, one end of the drench tube is inserted into the affected area in the body cavity of a patient who has undergone surgery, while the other end of the drench tube is connected to a vacuum pump to collect blood secreted from the affected area after surgery. This system uses a vacuum pump to suction body fluids such as the following through a drench tube and drain them out of the body. Blood and other discharges secreted from the affected area in the body cavity are seen intermittently for several days, and because they are secreted in small quantities, they tend to clot inside the drench tube, and when draining it, it is necessary to use a drain tube. The tube had to be squeezed and squeezed sequentially with a person's fingers from the patient side to the vacuum pump side, which not only caused hygiene problems but also relied on extremely inefficient work.

The present invention was devised in view of these points, and aims to provide a drench tube squeezing device that efficiently and reliably drains sticky waste such as blood, is easy to use, and does not cause hand fatigue. That is.

Next, drawings showing an embodiment of the present invention will be described. The substantially rectangular frame 1 has upper and lower side plates 3, 13, 3', and 13' divided into upper and lower halves, and stainless steel connecting plates 4 and 14 fixed to the upper and lower ends of the side plates, respectively. 2, 12 are formed. One side plate 3 of the upper and lower frame parts 2, 12 divided into upper and lower halves at approximately the center;
13 has each center end formed into a hinge shape and each connected to the shaft 2.
Pivot with 3. A set screw 11 that protrudes outward from the other side plate is provided in the center of the other side plate 3', 13' of the upper and lower frame parts 2, 12, which are divided vertically into two at approximately the center. The other side plate 1 of the lower frame part 12 is fixed to the other side plate 3' of the lower frame part 12 with screws.
A curved groove 18 is carved at a predetermined position of 3'. The set screw 11 is provided with a stopper 20 having a protrusion 19 that engages with the curved groove 18 of the other side plate 13' of the lower frame portion 12.
is rotatably mounted, and a handle 21 made of synthetic resin is provided which is screwed into the set screw 11. Rotatable mounting arms 8, 8' are pivotally supported by screws 9, 9' on both side plates 3, 3' forming the upper frame part 2 of the frame 1, respectively. A locking plate 10 made of stainless steel and having the same length as the longitudinal width of the upper frame portion 2 is provided on one side.
is fixed so that both mounting arms 8, 8' can only be rotated in the counterclockwise direction in FIG. A moving roller 5 made of synthetic resin and having annular step portions 7 and 7' at both ends is supported by a shaft 6 between both mounting arms 8 and 8'. Both side plates 13 forming the lower frame part 12 of the frame body 1,
Between 13' are stepped portions 7 at both ends of the moving roller 5,
7', and has a diameter large enough for the outer peripheral side to remain within the stepped portions 7, 7' at both ends.
Fixed rollers 15 made of synthetic resin each having a diameter 7' are supported by a shaft 16, and a predetermined gap 25 is formed between the movable roller 5 and the fixed roller 15.

In use, the handle 21 is rotated in the opposite direction to loosen the screw engagement with the set screw 11, and as shown in FIG. The lower frame part 12 is disengaged from the lower frame part 12, and the lower frame part 12 opens downwardly relative to the upper frame part 2 about the axis 23 of the hinge part (see the state diagram shown by the dashed-dotted line in FIG. 1). Next, move the drench tube A to the roller 5 so that the center line of the drench tube A and the axes of both rollers 5 and 15 in the frame 1 are perpendicular to each other.
and both flanges 17,1 of the fixed roller 15 opened.
7', the lower frame part 12 is rotated upward about the shaft 23 until the other side plate 13' of the lower frame part 12 comes into contact with the setscrew 11 in a reverse operation to the above, and the lower frame The portion 12 is closed, and the protrusion 19 of the stopper 20 is rotated back into the curved groove 18, and the handle 21 is closed.
When the drench tube A is rotated forward to tighten the screw engagement with the set screw 11, the drench tube A is pressed into a flat shape between both rollers 5 and 15 in the frame body 1. When the handle 21 is gripped by hand and any finger is placed on the locking plate 10, the frame body 1 is moved forward in the direction of the solid arrow shown in FIG. The movable roller 5 rotates oppositely to the movable roller 5 which is pivotally supported between the mounting arms 8 and 8' in the upper frame portion 2, and the movable roller 5 rotates oppositely to the locking plate 1 of both the mounting arms 8 and 8'.
0, the drench tube A does not move in the backward direction when moving forward, and the drench tube A does not move in the backward direction when moving forward.
The waste material a in the drench tube A is discharged by the advancement of the portion pressed by the two rollers 5 and 15.
In addition, in the case of sticky discharge material such as blood, it may not be thoroughly discharged with one press and advance.
If a part of the frame 1 remains, replace the frame 1 with
When the rollers 5 and 15 are moved backward in the direction of the dotted chain arrow, both the rollers 5 and 15 rotate in the opposite direction, and the mounting arms 8 and 8' of the movable roller 5 are attached to the respective screws relative to the fixed roller 15 in the fixed position of the lower frame portion 12. 9 and 9', and the moving roller 5 rises (fourth
(Refer to the state diagram shown by the dashed dotted line in FIG. 1), and release the pressure on the drench tube A. After returning the frame 1 with the gap between the rollers 5 and 15 widened to the rear of the drench tube A, the locking plate 10 of the upper frame portion 2 is returned to its original position by hand.
The drench tube A is again pressed between both rollers 5 and 15, and by moving the frame 1 forward again, it becomes possible to squeeze the same position of the drench tube A, and by pressing it forward again, it becomes sticky. This makes it possible to reliably discharge waste material a that tends to coagulate.
The drench tube A is connected to both rollers 5 and 5 by collars 17 and 17' respectively installed on the fixed roller 15.
Even if the lateral movement range between the rollers 5 and 15 is restricted, and even if the drench tube A is pushed forward in a slightly oblique direction, the drench tube A will move forward with both rollers 5 and 1.
It will not fall off from between 5 and 5.

In addition, in order to change the gap 25 between both rollers 5 and 15 in accordance with the diameter of the drench tube A, it is necessary to change the mounting position of the fixed roller 15, or to change the mounting position of the fixed roller 15, or to change the gap 25 between the rollers 5 and 15 in accordance with the diameter of the drench tube A. Adjustment screws are provided in contact with both side plates 3, 3' of the upper frame part 2 and their tips, and by adjusting the length of the adjustment screws, the movable roller 5 is rotated diagonally upward.
The present invention is not limited to the above-described embodiment.

As described in detail above, the present invention separates both side plates of the frame body to form upper and lower frame parts, and pivots one side plate of the upper and lower frame parts in a hinge-like manner so that these two frame parts can be opened and closed. A stopper is provided on the other side plate of the upper and lower frame portions to prevent both the frame portions from opening and closing, and a moving roller is provided between a pair of mounting arms rotatably supported on any one of the frame portions, and the moving roller is A locking plate is provided on the mounting arm so that it can only be moved in one direction.
A stationary roller is provided between the other frame portion and has a collar that prevents the drench tube from falling off when it is squeezed between it and the movable roller, so that the discharged material in the drench tube is removed by the forward pressure of both rollers. It can be drained efficiently and reliably, and even if sticky waste cannot be discharged at once, if the frame is moved back, the movable roller will rise in one direction and the frame can be easily returned, allowing the drain to drain again. This type of waste can be reliably discharged by squeezing the tube in the same position. In addition, the stoppers fall off and both frames can be opened and closed by hand, making them easy to handle, and the stoppers prevent both frames from opening during use, requiring manual labor to squeeze and discharge them one after another. Compared to the conventional case, it does not cause fatigue in the hands and fingers. Furthermore,
By providing the flanges on the stationary rollers, the drench tube can always be positioned between the two flanges, and has features such as not falling off the rollers.
