Description

Medical Suction Apparatus

The present invention relates to a medical suction device, and to a medical suction device having a suction head connected to the tube.

In general, a suction line connected to a vacuum pump or the like is installed in a wall of a hospital room or an operating room of a hospital, and a medical suction device is provided in order to adjust the suction pressure or to process the suctioned object by opening and closing a valve in the suction line. Is installed.

The conventional medical suction device is composed of a lower container that is largely assembled with the upper case and the upper case, the upper case is formed with a nozzle connected to the suction line on one side, a suction tube for sucking the object on the other side is formed, On the upper side is formed a control valve for adjusting the suction pressure.

In addition, the lower container is formed in a concave cup shape of which the upper side is open to accommodate the object sucked through the suction pipe therein, and is assembled to be detachable from the upper case.

The assembly method of the conventional lower container and the upper case is a very simple configuration, and is formed in a torsional coupling method by forming a screw portion that is twisted to each other at the periphery of the lower case and the lower container of the upper case, or the upper portion of the upper case. Lever pull and release type were installed by installing the latch and the latch lever using the principle of the lever in the lower part of the case and the periphery of the lower container, respectively.

However, this torsional or lever pull / unlock method requires the user to hold the lower container with one hand, twist the lower container with the other hand, pull or release the lever with the other hand in the process of separating the lower container from the upper case. The user's two hands are necessarily required, and the twisting or pulling operation is cumbersome, making the user uncomfortable, and of course, spilling the object by mistake of operation.

Such inhalation devices are also used in surgery to treat underpressure for the purpose of promoting healing of wounds. In order to treat the wound using negative pressure, the procedure was performed through a porous pad made of a surgical drape and an open cell polymer to reduce infection and facilitate treatment of the skin around the incision. .

This negative pressure vacuum induction process was recently popularized by Kinetic Concepts, Inc. of San Antonio, Texas, and the commercially available Va.A.C. (Vacuum Assisted Closure) product line. Such vacuum induction treatment processes are disclosed in US Pat. No. 4,969,880, US Pat. No. 5,100,396, US Pat. No. 5,261,893 and US Pat. No. 5,527,293, respectively. Moreover, improvements and modifications of the vacuum induction treatment process are disclosed in US Pat. No. 5,636,643, US Pat. No. 5,645,081, and US Pat. No. 6,142,982.

The treatment process using this negative pressure is as follows. First, a porous pad attached to the wound is attached, and a surgical drape is attached to cover the wound and the porous pad together to seal the wound. When the wound is closed, one end of the drain tube is directly inserted into the porous pad and a vacuum generator connected to the other end of the drain tube is driven to generate a negative pressure inside the drape. The exudates discharged from the wound are absorbed by the porous pad and drained. The wound is closed by discharge into the tube. In this case, the porous pad maintains a predetermined gap between the wound surface and the drape to maintain a negative pressure inside the drape to help the exudates smoothly escape through the drain tube.

However, when the drain tube is directly inserted into the porous pad in this manner, exudates from the wound near the end of the drain tube are absorbed in a circular manner, while exudates remote from the end of the drain tube are smoothly sucked into the drain tube. As a result, the treatment for wound closure caused by negative pressure is slow.

In order to solve this problem, as disclosed in Korean Patent Registration No. 516,288, a suction head has been proposed to facilitate inhalation of exudate from the wound. The suction head has a flange portion compressed on the upper side of the porous pad and a connecting pipe for connecting the drain tube to the upper side thereof. In this case, at the bottom of the flange portion, several hemispherical protrusions are formed at intervals to define a flow channel for promoting fluid flow so as to smoothly guide the exudates absorbed by the porous pad to the connecting pipe. In this case, the suction head was used in combination with a surgical drape comprising a thin soluble adhesive coated plastic film to secure the assembly to the open side of the porous pad and the patient's skin.

However, in the conventional suction head, since several hemispherical protrusions are irregularly disposed at the center where the negative pressure is concentrated, the length of the flow path guided from the various parts of the porous pad to the connector is not constant and in some cases around the connector. Increasingly, the flow path is concentrated in one place, which acts as an obstacle to moving the exudate to the connecting pipe, and it is difficult to discharge the exudate to the drain tube smoothly.

In addition, the suction head of the conventional suction device is often easily separated when the patient moves after connecting the drain tube to the connection tube, which causes the wound to be exposed to indoor air and thus wounds on various bacteria contained in the air. There is a problem of contamination, in which case the medical staff has to replace the new suction head immediately.

In order to solve this problem, the suction head and the drain tube are completely fixed with adhesive, etc. In this case, when the suction head is fixed to the wound by the drape, the drain tube cannot be brought into close contact with the suction head. There is a problem that the negative pressure set in the inner side is not generated, so that the exudates are difficult to remove, thus delaying recovery of the wound.

In addition, since most of the vacuum generators of the suction device using the suction head use an electric type, the device is large and inconvenient to carry.

Accordingly, an object of the present invention is to facilitate the discharge of the exudates absorbed by the porous pad to the drain tube, and has a suction head that can secure the coupling of the drain tube and the connection of the suction head, easy to carry The present invention provides a medical inhalation apparatus that can be miniaturized to be easily used and easy to maintain a vacuum state by easily adjusting the pressure by a manual simple operation.

Hereinafter, with reference to the accompanying Figures 1 to 13 will be described in detail a preferred embodiment of the present invention.

1 is a perspective view of a state of use of the suction device according to an embodiment of the present invention.

Referring to FIG. 1, in the suction device of the present invention, the suction head 100 and the vacuum generator 300 are connected by a drain tube 200. The suction device according to the present invention guides a suction head 100 for sucking exudates, a discharge bin 500 for discharging the exudates from the suction head 100, and a path through which the exudates are discharged to the discharge bin 500. And a drain tube 200 for transmitting a negative pressure, connected to the suction head 100 and the drain tube 200, and a vacuum generator 300 generating negative pressure to the suction head 100. That is, the suction head 100 is connected to one side of the drain tube 200, and the vacuum generator 300 is connected to the other side. On the drain tube 200 may include a pressure gauge (G) indicating the current negative pressure. Usually, the gauge pressure is preferably 50 mmHg to 200 mmHg, most preferably 125 mmHg.

The vacuum generator 300 includes a frame 380 for supporting the device, a handle 350 for manual pumping on one side of the frame, a cylindrical cylinder 320 for piston movement by a pumping operation of the handle 350, The piston 320 includes a piston ring 340 and a spring 330. In addition, the end of the cylindrical cylinder 320 includes a tube connector 310 for connecting with the drain tube 200.

In the suction device of FIG. 1, the suction head 100 is fixed by the drape 30 so that exudates can be discharged, and then the frame is held by the user's finger on the handle 350 of the vacuum generating device 300. If the piston ring 340 moves forward and backward while pulling toward the 380, air is introduced and discharged into the cylindrical cylinder 320.

At this time, by appropriately pulling the piston handle 350 of the vacuum generating device 300 can not only regulate the discharge rate or discharge of the exudates from the suction head 100 by the air suction force sucked into the cylinder 320, but also suction Since the inside of the head from the head 100 to the tube connector 310 of the vacuum generator 300 is set to a vacuum state, discharge of the exudates is continuously made without the piston ring 340 moving forward and backward.

After the discharge of the exudate is completed in the above-described state, the user may open the exudate discharge container 500 to remove the exudate.

First, the suction head of the suction device of FIG. 1 will be described with reference to FIGS. 2 to 8.

FIG. 2 is a plan view of the suction head according to the suction device of FIG. 1, FIG. 3 is a sectional view taken along the line II-II shown in FIG. 2, FIG. 4 is a bottom view of the suction head according to the suction device of FIG. 1, and FIG. 5 is a schematic diagram showing a drain tube connected to a suction head according to the suction device of FIG. 1.

2 to 5, the medical suction head 100 is formed in a plane and has a first surface (ie, an upper surface) and a center in which a connecting tube 130 is connected to a drain tube 200 at a central portion thereof. A communication hole 113 formed in communication with the connection pipe 130, and a plurality of single flow paths formed in partial contact with the porous pad 20 (see FIG. 6) to prevent the exudates from mixing with each other. It includes a second surface (that is, lower surface) having a plurality of guide channels 111 to guide to.

The suction head 100 includes a flange portion 110 and the connection pipe 130 when divided into shapes. That is, the flange portion 110 having the first surface (ie, the upper surface) and the second surface (that is, the lower surface) is attached to the wound portion 11 of the skin 10 (see FIG. 6). 6 and 7) a plurality of guide channels on one side in contact with the porous pad 20 to guide the exudates absorbed by the porous pad 20 to be collected into the communication hole 113 in contact with the top surface of the filter. 111 is formed, and a communication hole 113 communicating with the connecting pipe 130 is formed in the center thereof.

The plurality of guide channels 111 collect the exudates into the communication holes 113 of the connection pipe 130, and form a plurality of single flow paths so that the exudates do not mix with each other. In order to form such a single flow path, the plurality of guide channels 111 are formed radially around the communication hole 113 and have a groove shape, for example, a groove structure having a trench, hemisphere, or triangle shape in cross section. In this case, the angle θ between the plurality of guide channels 111 may be set to, for example, about 30 degrees for smooth transfer of the exudates. However, the angle θ between the plurality of guide channels 111 may vary depending on the size of the wound 11 (see FIG. 6), that is, the size of the diameter of the flange 110 or the amount of exudates.

In addition, since the flange 110 is generally smaller than the porous pad 20 (see FIG. 6), the plurality of guide channels 111 may be flanged to effectively transport the exudates absorbed on the outer periphery of the porous pad 20. It is formed to extend from the outer circumferential end of the 110 to the communication hole 113, in this case the plurality of guide channels 111 are formed in a straight line so that the communication hole 113 is the shortest distance from the outer circumferential end of the flange portion 110 It is preferable to set as possible.

For example, the plurality of guide channels 111 are formed to have a straight line, but the present invention is not limited thereto. The guide channels 111 may be formed to have a curvature. The three guide channels 111 are preferably formed so as not to cross each other.

In addition, when the flange portion 110 is attached to the skin 10 in a state in which the drape 30 (see FIG. 7) is attached to the other side of the flange portion 110, the flange portion 110 is formed by the edge 112 of the flange portion 110. The drape 30 is rounded to prevent tearing. Accordingly, as the drape 30 is torn, the negative pressure formed between the skin and the drape 30 can be prevented from being destroyed.

Moreover, the flange portion 110 may be formed in a circular or oval shape, and may be manufactured in various sizes according to the size of the wound portion 11.

The connecting tube 130 is integrally formed and includes a first pipe part 131 communicating with the communication hole 113 and a second pipe part 133 connected to the drain tube 200.

The first pipe part 131 protrudes from the other side surface of the flange part 110 in a state where one end is in communication with the communication hole 113. The first pipe part 131 is formed to have a predetermined height in a direction substantially perpendicular to the flange part 110.

The second pipe part 133 is extended so that one end is bent at right angles to the other end of the first pipe part 131 so that the drain tube 200 is disposed adjacent to the body of the patient when the drain tube 200 is connected to the drain tube 200. The two pipe portions 133 are formed to be substantially parallel to the flange portion 110. As such, the second tube portion 133 is bent to prevent the drain tube 200 from interfering with the treatment.

In addition, the second pipe part 133 is provided with a fastening hole 135 into which one end of the drain tube 200 is connected. In this case, a female tooth portion 137 is formed at an inner circumference adjacent to the fastening hole 135 of the second tube portion 133, and a male tooth portion which is fastened and inserted into the female tooth portion 137 at one end of the drain tube 200. (210: see FIG. 5) are formed respectively. In this case, the female and male teeth 137 and 210 (see FIG. 7) are inclined in a reverse direction with respect to the direction in which the drain tube 200 is inserted into the fastening hole 135 of the second pipe portion 133. The inclined direction of the female and male teeth 137 and 210 is to prevent the drain tube 200 from being separated when the drain tube 200 is inserted into the fastening hole 135 of the second pipe 133. The female / female teeth 137 and 210 are preferably designed and manufactured to have a proper tolerance so that a negative pressure can be formed and maintained by a vacuum generator after the fastening.

In addition, the coupling structure between the second pipe part 133 and the drain tube 200 may be formed by a screw coupling method in addition to the female / male teeth parts 137 and 210, and a sealing packing may be added as necessary.

Meanwhile, the suction head 100 may be packaged or individually packaged together with the porous pad 20, the drape 30, and the drain tube 200, or may be sterilized by gamma rays. In addition, the material of the suction head 100 is preferably silicone rubber or PVC material to use a relatively transparent material having elasticity that does not seriously affect the strength even if it is not modified or denatured by gamma ray sterilization.

6 to 8 will be described with reference to the attached method for fixing to the wound portion 11 using the suction head 100 described above.

6 is a cross-sectional view showing a state in which the porous pad is attached to the wound of the patient, Figure 7 is a suction head of the suction device of Figure 1 fixed to the upper side of the porous pad, the drape is attached together to maintain airtight in this part Figure 8 is a side cross-sectional view showing a state, Figure 8 is a side cross-sectional view showing a state in which the drain tube is connected to the suction head of the suction device of FIG.

First, as shown in FIG. 6, a porous pad 20 made of an open cell polymer is attached to the wound 11 of the skin 10 so as to effectively suck the exudate.

Subsequently, the flange 110 of the suction head 100 is seated in an approximately center portion of the porous pad 20.

Thereafter, the connecting tube 130 is passed through the opening 31 of the surgical drape 30, and the protective film (not shown) of the drape 30 is removed to remove the protective film (not shown) of the drape 30 and the drape 30. ) Is completely in contact with each other, and as shown in FIG. 7, the outer periphery of the drape 30 is completely in contact with the wound 10 of the skin 10 so that no vacuum leaks around the skin 10 and the drape ( 30) Sealed so that a negative pressure can be formed between them.

Thereafter, as shown in FIG. 8, the male teeth 210 of the drain tube 200 are inserted into the fastening holes 135 of the second tube 133 to fasten the female / female teeth 137 and 210 to each other. As a result, the drain tube 200 is not separated from the connecting pipe 130 by the female / male teeth 137 and 210.

In this state, when the vacuum generator 300 connected to the other end of the drain tube 200 is operated, a negative pressure is formed between the skin 10 and the drape 30. Accordingly, the exudates of the wound 11 are absorbed into the porous pad 20 and then guided to the communication hole 113 through the plurality of guide channels 111 formed in the flange 110.

Thereafter, the exudates are introduced into the communication hole 113 and then transferred along the drain tube 200 via the connection pipe 130 and finally collected into the discharge container 500.

As such, when performing the negative pressure treatment of the wound site through the medical suction head 100 according to the embodiment of the present invention, the exudates absorbed by the porous pad are not mixed with each other through the plurality of guide channels 111 at the shortest distance. By guiding to the communication hole 113, smooth inhalation of the exudate can be induced.

Furthermore, when the connection tube 130 and the drain tube 200 are combined with each other by the female / female portions 137 and 210 once again, the drain tube 200 is separated during the treatment to separate the connection tube 130 into the connection tube 130. By blocking the inflow of air in advance, it is possible to fundamentally prevent the wound 11 from being exposed to bacteria contained in the air.

The vacuum generating apparatus 300 for operating the suction head 100 will be described in detail with reference to FIGS. 9 to 11 below.

FIG. 9 is a cross-sectional view of the vacuum generator according to the suction device of FIG. 1, and FIGS. 10A and 10B are enlarged cross-sectional views of part "A" of FIG. 9, and FIGS. 11A and 11B are part "B" of FIG. 9. It is an enlarged cross section.

Referring to FIG. 9, the vacuum generating device 300 includes a cylindrical cylinder 320 having a tube connector 310 at one end and a handle 350 at the other end. The cylinder 320 is coupled to the spring 330 is installed therein and the rubber piston ring 340 is slid in the cylinder 320 at one end thereof. One end of the cylinder 320 is fixedly coupled to the frame 380 by using a fixed capping 371. In addition, a suction valve 301 having a cutout 301a formed at the inlet side of the tube connector 310 inside the cylinder 320 is installed.

The front portion of the cylinder is configured to be coupled to the fixed cap 306 by installing an air discharge valve 302 operated up and down by the spring 305 elasticity in the coupling portion 304 is formed in the air hole 303. Here, FIG. 10A shows a state in which the air discharge valve 302 is lifted upward by the elastic force of the spring 305 to block the air hole inside the cylinder 320. In addition, FIG. 10B shows a state in which the air discharge valve 302 is pushed downward to open the air hole to allow air inside the cylinder 320 to escape to the outside.

11A is a cross-sectional view illustrating a state in which air is sucked into the cylinder 320 through a cutout of the intake valve 301, and FIG. 11B is a view of blocking the cutout of the intake valve 301 to the outside. This is a cross-sectional view showing a state that can not escape.

Looking at the operation of the vacuum generator 300 in detail with reference to each of these parts, in Figure 9, when the handle 350 is pulled toward the frame 380, the piston ring 340 is retreat and installed at the inlet of the tube connector 310 As the cutout 301a of the intake valve 301 opens, air flows into the cylinder 320. In addition, when the handle 350 is released, the piston ring 340 tries to return to its original position due to the spring force of the spring 330, but air is not discharged to the outside while the cutout 301a of the intake valve 301 is blocked. Since the piston ring 340 is not advanced.

At this time, when the air discharge valve 302 formed on the cylinder 320 is pushed downward, the piston ring 340 is advanced while the air in the cylinder 320 escapes. Then, when the air discharge valve 302 is released, the air discharge valve 302 is lifted upward by the elastic force of the spring 330 to block the air hole 303 of the cylinder 320 to the initial state. will be.

When the user repeatedly pulls and releases the handle 350, the piston ring 340 moves forward and backward and the exudates are sucked into the suction head 100 and stored in the discharge container 500.

At this time, by appropriately pulling the piston handle 350 of the vacuum generating device 300, the discharge rate or the discharge amount of the exudate can be adjusted by the air suction force sucked into the cylinder 320. In addition, as the cutout 301a of the intake valve 301 installed inside the cylinder 320 is blocked, the air inside the cylinder 320 does not move toward the suction head 100, so the inside is vacuumed, thereby continuously exuding the exudates. It is inhaled. At this time, the pressure gauge can also check the pressure.

In the suction apparatus according to the above-described embodiment, the exudant discharge container is disposed on one side of the drain tube connected to the vacuum generator, but the exudant discharge container may be integrally formed with the vacuum generator to perform the same operation from the suction head.
