Description

Drain pipe squeezing device {SQUEEZING DEVICE FOR DRAINAGE TUBE}

The present invention relates to a drain pipe squeezing device capable of automatically squeezing the drain pipe.

BACKGROUND OF THE INVENTION After a surgical operation, bodily fluid (hereinafter referred to as "drainage") that collects in tissues interferes with wound healing and causes complications. Therefore, after closing the surgical window so that the drainage does not accumulate in the tissue after surgery, a drainage tube is inserted into the surgical site to discharge the drainage accumulated inside the surgical window outside the body.

The drainage tube is used to remove drainage from the body after surgery and has a tube shape made of a flexible material. However, when hematoma, necrosis, blood clot, etc. are present in the drainage fluid delivered from the surgical site to the drainage tube, the viscosity of the drainage fluid increases. As a result, as the drain fluid is stored in the drain pipe, the drain pipe is clogged. Therefore, in a medical field, a medical person frequently squeezes or milks the drainage tube to perforate it.

Here, squeezing the drain pipe means squeezing the drain fluid stored in the drain pipe by pressing the drain pipe in the longitudinal direction. In addition, milking the drain pipe means to soften the drain fluid stored in the drain pipe by pressing the drain pipe.

Conventionally, squeezing or milking of the drainage tube was performed manually by medical personnel.

However, in a medical field, there is a problem in that squeezing or milking of the drainage tube is delayed or improperly performed as one medical person cares for several patients.

Advantages and features of the present invention, and methods of achieving them, will become clear with reference to the detailed description of the following embodiments taken in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, and only these embodiments are provided to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the present invention to which the present invention belongs, and the present invention is only defined by the scope of the claims.

Terminology used herein is for describing the embodiments and is not intended to limit the present invention. In this specification, singular forms also include plural forms unless specifically stated otherwise in a phrase. As used herein, "comprises" and/or "comprising" does not exclude the presence or addition of one or more other elements other than the recited elements. Like reference numerals throughout the specification refer to like elements, and “and/or” includes each and every combination of one or more of the recited elements. Although "first", "second", etc. are used to describe various components, these components are not limited by these terms, of course. These terms are only used to distinguish one component from another. Accordingly, it goes without saying that the first element mentioned below may also be the second element within the technical spirit of the present invention.

Unless otherwise defined, all terms (including technical and scientific terms) used in this specification may be used with meanings commonly understood by those skilled in the art to which the present invention belongs. In addition, terms defined in commonly used dictionaries are not interpreted ideally or excessively unless explicitly specifically defined.

Drainage tubes can be classified into pancreatobiliary drainage tubes, pleural fluid drainage tubes, nasogastric tubes, gastrostomy tubes, chest tubes, and surgical drainage tubes according to their material and diameter.

Since the pancreatobiliary drainage tube is made of an inflexible material, squeezing is impossible. When the tube is blocked by the drainage stored in the tube, physiological saline can be injected to remove the drainage stored in the tube.

The pleural fluid drainage tube maintains natural drainage and may not undergo any physical manipulation, including infusion of physiological saline.

The nasogastric tube and gastrostomy tube are inserted to discharge bleeding debris or foreign substances, and if the tube is blocked by the drainage stored in the tube without squeezing, the drainage stored in the tube can be removed by injecting physiological saline.

Squeezing of the chest tube can be attempted carefully if the drainage is bloody, but as negative pressure is generated in the chest tube, there is a risk of tissue damage or bleeding in the surgical site, so there is a trend to limit it, and squeezing is not performed if there are no noticeable foreign substances.

The surgical drainage tube can insert catheters of various inner diameters and lengths for each surgical site, and since it is made of a flexible material, when the tube is blocked by the drainage stored in the tube, the drainage stored in the tube can be removed through squeezing.

That is, the pancreaticobiliary drainage tube, pleural fluid drainage tube, nasogastric tube, gastrostomy tube, and chest tube cannot or have difficulty squeezing the drainage accumulated in the tube, but the surgical drainage tube can squeeze the drainage accumulated in the tube.

Therefore, the drainage pipe squeezing device according to an embodiment of the present invention is preferably used for squeezing the drainage fluid stored in the surgical drainage pipe, but the present invention is not limited thereto.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view showing a drain pipe squeezing device according to an embodiment of the present invention, and FIG. 2 is a side view showing a drain pipe squeezing device according to an embodiment of the present invention.

As shown in FIGS. 1 and 2 , the drain pipe squeezing device according to an embodiment of the present invention includes a main body 100 , a squeezing member 200 and a driving unit 300 . Overall, the main body 100 includes a first holding member 110 on which one side of the drain pipe 10 is mounted, and a second holding member 120 disposed to be spaced apart from the first holding member 110 and holding the other side of the drain pipe 10. It is provided to be movable along the drain pipe 10 while pressing the drain pipe 10 while squeezing the drained fluid inside the drain pipe 10, and the driving unit 300 moves the squeezing member 200.

The main body 100 is a basic body of the present invention, and may include a first holding member 110, a second holding member 120, and a track 130.

The first holding member 110 and the second holding member 120 serve to hold both sides of the drain pipe 10, respectively, and the track 130 serves to guide the movement of the squeezing member 200.

The first mounting member 110 may be provided on one side of the main body 100 . For example, a first mounting groove 111 may be formed on a side surface of the first mounting member 110 along a transverse direction of the longitudinal direction of the drain pipe 10 . Therefore, one side of the drain pipe 10 can be easily inserted into and mounted in the first mounting groove 111 provided on the side surface of the first mounting member 110 .

Furthermore, a first protrusion 112 protruding toward the drain pipe 10 mounted in the first mounting groove 111 may be formed on an inner surface of the first mounting groove 111 . The first protrusion 112 serves to support the drain pipe 10 mounted in the first mounting groove 111 . For example, the first protrusions 112 may be configured as a pair, and the pair of first protrusions 112 may support both sides of the drain pipe 10 mounted in the first mounting groove 111 .

The second mounting member 120 may be provided on the other side of the main body 100 . For example, a second mounting groove 121 may be formed on a side surface of the second mounting member 120 along a transverse direction of the longitudinal direction of the drain pipe 10 . Therefore, the other side of the drain pipe 10 can be easily inserted into the second mounting groove 121 provided on the side surface of the second mounting member 120 and mounted thereon.

Furthermore, a second protrusion 122 protruding toward the drain pipe 10 mounted in the second mounting groove 121 may be formed on an inner surface of the second mounting groove 121 . The second protrusion 122 serves to support the drain pipe 10 mounted in the second mounting groove 121 . For example, the second protrusions 122 may be configured as a pair, and the pair of second protrusions 122 may support both sides of the drain pipe 10 mounted in the second mounting groove 121 .

The track 130 is provided between the first holding member 110 and the second holding member 120 and guides the movement of the squeezing member 200 . That is, the squeezing member 200 moves along the track 130 .

The track 130 may include a first track 131 provided to face one surface of the drain pipe 10 between the first holding member 110 and the second holding member 120, and a second track 132 provided to face the other surface of the drain pipe 10 between the first holding member 110 and the second holding member 120.

The first track 131 is disposed facing the second track 132 with the drain pipe 10 interposed between the first holding member 110 and the second holding member 120 . A first movable body 210 to be described later may move along the first track 131 . At this time, the first track 131 and the first movable body 210 may be dovetail coupled. For example, as the first track 131 has a male dovetail shape and the first movable body 210 has a female dovetail shape, the first track 131 and the first movable body 210 may be dovetail coupled.

The second track 132 is disposed facing the first track 131 with the drain pipe 10 interposed between the first holding member 110 and the second holding member 120 . A second movable body 220 to be described later may move along the second track 132 . At this time, the second track 132 and the second movable body 220 may be dovetail coupled. For example, as the second track 132 has a male dovetail shape and the second movable body 220 has a female dovetail shape, the first track 131 and the first movable body 210 may be dovetail coupled.

The squeezing member 200 is provided to be movable along the drain pipe 10 between the first holding member 110 and the second holding member 120, and compresses the drain pipe 10 while moving. It serves to squeeze the drainage inside the drain pipe 10. The squeezing member 200 may move along the track 130 provided between the first holding member 110 and the second holding member 120 .

On the other hand, the squeezing member 200 may be provided with a squeezing roll 240 that is rollable and pressurizes or non-pressurizes the drain pipe 10 .

When the squeezing member 200 moves, the squeezing roll 240 presses the drain pipe 10 while rolling along the drain pipe 10 to squeeze the drainage inside the drain pipe 10 . Furthermore, when the squeezing member 200 moves, as the squeezing roll 240 rolls along the drain pipe 10, the squeezing member 200 may move smoothly.

The squeezing roll 240 may be rotatably coupled to a support shaft 250 penetrating the squeezing member 200 . Furthermore, an accommodation space in which the squeezing roll 240 is partially accommodated may be formed in the squeezing member 200 .

The squeezing member 200 may include a first movable body 210 , a second movable body 220 and an elastic member 230 .

The first movable body 210 may move along the first track 131 and pressurize or non-pressurize one surface of the drain pipe 10 . A first movable groove 211 sliding along the first track 131 may be provided on the outer surface of the first movable body 210 . The first moving groove 211 may be formed in a shape corresponding to the first track 131 . In addition, a squeezing roll 240 may be provided on the inner surface of the first movable body 210 . (See Fig. 3)

The second movable body 220 may move along the second track 132 and pressurize or non-pressurize one surface of the drain pipe 10 . A second movable groove 221 sliding along the second track 132 may be provided on the outer surface of the second movable body 220 . The second movable groove 221 may be formed in a shape corresponding to the first track 131 . In addition, a squeezing roll 240 may be provided on the inner surface of the second movable body 220 . (See Fig. 3)

The elastic member 230 is provided between the first movable body 210 and the second movable body 220 to elastically support the first movable body 210 and the second movable body 220 . Therefore, by the elastic support of the elastic member 230, the first movable body 210 and the second movable body 220 can always maintain a predetermined distance. (See Fig. 3)

Meanwhile, the first track 131 and the second track 132 may include a non-pressurized path portion 133 and a pressurized path portion 134 .

The non-pressurized path portion 133 may be formed in one region of the first track 131 and the second track 132, and in the non-pressurized path portion 133, the first movable body 210 and the second movable body 220 may move together without pressurizing the drain pipe 10. Specifically, in the non-pressurized path portion 133, the distance between the first movable body 210 disposed on the first track 131 and the second movable body 220 disposed on the second track 132 may be larger than the diameter of the drain pipe 10. Therefore, when the first movable body 210 and the second movable body 220 are disposed in the non-pressurized path portion 133, the drain pipe 10 can be easily inserted between the first movable body 210 and the second movable body 220. Additionally, as the first movable body 210 and the second movable body 220 move while maintaining a distance greater than the diameter of the drain pipe 10 in the non-pressurized path portion 133, the first movable body 210 and the second movable body 220 can move together without pressurizing the drain pipe 10.

The pressurized path part 134 may extend from one area of the non-pressurized path part 133 or from an end of the non-pressurized path part 133, and the first movable body 210 and the second movable body 220 together pressurize the drain pipe 10 and move. Specifically, in the non-pressurized path portion 133, the distance between the first movable body 210 moving along the first track 131 and the second movable body 220 moving along the second track 132 may be smaller than the diameter of the drain pipe 10. Therefore, as the first movable body 210 and the second movable body 220 move while maintaining a distance smaller than the diameter of the drain pipe 10 in the pressurization path part 134, the first movable body 210 and the second movable body 220 can pressurize the drain pipe 10 and move together.

If the non-pressurized path portion 133 and the pressurized path portion 134 are described again based on the distance between the first track 131 and the second track 132, the distance between the first track 131 and the second track 132 in the non-pressurized path portion 133 may be formed larger than the distance between the first track 131 and the second track 132 in the pressure path portion 134.

Additionally, the first track 131 and the second track 132 may include an access path portion 135 .

The access path part 135 may be provided between the non-pressurized path part 133 and the pressurized path part 134, and in the access path part 135, the first movable body 210 and the second movable body 220 may move in a direction approaching the drain pipe 10 together. Specifically, in the access path part 135, the distance between the first movable body 210 moving along the first track 131 and the second movable body 220 moving along the second track 132 may be narrower as it approaches the pressure path part 134. Therefore, in the access path part 135, the first movable body 210 and the second movable body 220 may move in a direction approaching the drain pipe 10 together.

Meanwhile, in the first track 131 and the second track 132 in the above-described embodiment, the non-pressurized path portion 133, the access path portion 134, and the pressurized path portion 135 are sequentially arranged to form one path, but is not limited thereto.

3 is a perspective view showing a drive unit of a drain pipe squeezing device according to an embodiment of the present invention, and FIG. 4 is a perspective view showing a drive unit and a squeezing member of a drain pipe squeezing device according to an embodiment of the present invention.

As shown in FIGS. 1 to 4 , the driving unit 300 may include a screw shaft 310 , a driving motor 320 , and a moving nut 330 .

The screw shaft 310 may be provided along the moving direction of the squeezing member 200 in the main body 100 . Specifically, male threads are formed on the outer circumferential surface of the screw shaft 310 along the longitudinal direction, and a moving nut 330 to be described later is screwed to these threads.

The driving motor 320 serves to rotate the screw shaft 310 .

For example, the drive motor 320 may be disposed in line with the screw shaft 310, and the drive shaft of the drive motor 320 may be directly coupled to the screw shaft 310. Accordingly, when the driving shaft of the driving motor 320 is driven, the screw shaft 310 may be rotated.

As another example, referring to FIG. 4 , the drive motor 320 may be disposed perpendicularly to the screw shaft 310, the first bevel gear 350 is coupled to the drive shaft of the drive motor 320, and the screw shaft 310. As the second bevel gear 360 gear-coupled with the first bevel gear 350 is coupled, the drive motor 320 and the screw shaft 310 may be gear-coupled. Accordingly, when the driving shaft of the driving motor 320 is driven, the screw shaft 310 may be rotated. In this case, as the drive motor 320 is disposed perpendicularly to the screw shaft 310, the overall length may be reduced.

The moving nut 330 is screwed to the screw shaft 310, reciprocates along the screw shaft 310 when the screw shaft 310 rotates forward and backward, and is coupled to the squeezing member 200. Specifically, a female thread screwed into a male thread of the screw shaft 310 may be formed on an inner circumferential surface of the moving nut 330 .

Referring to FIG. 3 , the moving nut 330 and the squeezing member 200 may be coupled through a connecting member 340 .

One side of the connecting member 340 is connected to the movable nut 330, and the other side of the connecting member 340 has a sliding groove 341 coupled to allow the first movable body 210 and the second movable body 220 to approach or separate from each other. A sliding groove 341 may be formed. On one side of the sliding groove 341, the support shaft 250 passing through the first movable body 210 is slidably and rotatably coupled along the sliding groove 341, and on the other side of the sliding groove 341, the supporting shaft 250 passing through the second movable body 220 can be slidably and rotatably coupled along the sliding groove 341.

Accordingly, the first movable body 210 and the second movable body 220 may slide while approaching or spaced apart from each other along the sliding groove 341 .

In addition, as the support shaft 250 is rotatably coupled to the sliding groove 341, the first movable body 210 and the second movable body 220 passing through the support shaft 250 can also slide in a rotatable state.

Meanwhile, the drainage pipe squeezing device according to an embodiment of the present invention may further include a first coupling member 410, a second coupling member 420, a pressure measuring unit 500, a drainage detection sensor 600, and a control unit 700.

The first coupling member 410 may be provided on the main body 100 and detachably coupled to the drain pipe 10 . This first coupling member 410 may be formed in the shape of tongs.

The second coupling member 420 is provided on the main body 100 and can be detachably coupled to an external structure such as a bed handrail. This second coupling member 420 may be formed in the shape of tongs.

The pressure measuring unit 500 serves to measure the pressure inside the drain pipe 10 . The pressure measuring unit 500 is provided on the first protrusion 112 and can calculate the pressure inside the drain tube 10 by measuring the pressure applied from the drain tube 10 to the first protrusion 112 . For example, a pressure sensor may be used as the pressure measuring unit 500 .

The control unit 700 may adjust the number of operations of the driving unit 300 according to the data measured by the pressure measuring unit 500 . Here, the operating frequency of the driving unit 300 once may mean that the driving unit 300 completely moves the squeezing member 200 along the drain pipe 10 between the first holding member 110 and the second holding member 120.

The control unit 700 may increase the number of operations of the driving unit 300 as the data value measured by the pressure measurement unit 500 increases, and may decrease the number of operations of the driving unit 300 as the data value measured by the pressure measurement unit 500 decreases.

The drain detection sensor 600 is provided on the main body 100 to detect whether or not the drain remains inside the drain pipe 10 . The drainage detection sensor 600 is provided on the first protrusion 112, irradiates sensing light toward the drainage pipe 10, and detects whether or not drainage fluid remains inside the drainage pipe 10 according to a color change of the sensing light reflected from the drainage pipe 10. For example, an optical sensor may be used as the wastewater detection sensor 600 .

The control unit 700 may control operation or stop of the driving unit 300 according to data detected by the drainage detection sensor 600 . Specifically, the control unit 700 operates the driving unit 300 while the drainage liquid inside the drainage pipe 10 is detected by the drainage detection sensor 600 . In addition, the control unit 700 stops the driving unit 300 when drainage is not detected inside the drainage pipe 10 by the drainage detection sensor 600 .

Hereinafter, an operation example of squeezing the drain pipe 10 by the drain pipe squeezing device according to an embodiment of the present invention will be described.

5 to 7 are operational diagrams showing a drain pipe squeezing device according to an embodiment of the present invention.

First, as shown in FIG. 5 , the drive unit 300 moves the first movable body 210 and the second movable body 220 to the non-pressurized path part 133 . When the first movable body 210 and the second movable body 220 are disposed in the non-pressurized path portion 133, the drain pipe 10 can be inserted between the first movable body 210 and the second movable body 220.

Next, both sides of the drain pipe 10 are mounted on the first holding member 110 and the second holding member 120, respectively. In this case, one side of the drain pipe 10 can be easily inserted and mounted into the first mounting groove 111 provided on the side surface of the first mounting member 110 . In addition, the other side of the drain pipe 10 can be easily inserted into the second mounting groove 121 provided on the side surface of the second mounting member 120 and mounted thereon.

Next, the main body 100 is fixed to the drain pipe 10 using the first coupling member 410, and the main body 100 is fixed to an external structure such as a bed railing using the second coupling member 420.

Next, the driving unit 300 moves the first movable body 210 and the second movable body 220 . Then, as shown in FIG. 6 , when the first movable body 210 and the second movable body 220 move along the access path 135, they approach the drain pipe 10. After that, as shown in FIG. 7, when the first movable body 210 and the second movable body 220 move along the pressure path 134, both sides of the drain pipe 10 are pressed while draining the drain inside the drain pipe 10. The fluid is squeezed out.

Meanwhile, the number of operations of the drive unit 300 may be adjusted by the control unit, and the control unit 700 controls the number of operations of the drive unit 300 according to the pressure value inside the drain pipe 10 measured by the pressure measuring unit 500.

In addition, the operation or stop of the driving unit 300 may be determined by the control unit, and the control unit 700 operates the driving unit 300 while the drainage detection sensor 600 detects the drainage inside the drainage tube 10, and stops the driving unit 300 when the drainage detection sensor 600 does not detect the drainage inside the drainage tube 10.

According to the present invention, the drain pipe squeezing device according to an embodiment of the present invention has the advantage of being able to automatically squeeze the drain pipe and preventing the drain pipe from being clogged by the drain fluid stored in the drain pipe.

In the above, the embodiments of the present invention have been described with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains may be embodied in other specific forms without changing the technical spirit or essential features of the present invention.
