The medical suction device illustrated in the drawing may include a receiving unit 130, a frame unit 110, a drain valve 118, and an elastic part 150.

The accommodation unit 130 may be provided with an accommodation space sealed from the outside. The accommodation space can accommodate body fluid sucked from the affected part of the patient. The volume of the accommodation space may be greater at the second time point than at the first time point so that a negative pressure for inhaling body fluid is formed. In this case, the second time point may be a time point later than the first time point. 1, a plate-shaped accommodating unit 130 is disclosed. The accommodating unit 130 may be folded and sealed at an edge thereof to have an accommodating space as shown in FIG. 4 or 5.

In addition, the accommodation unit 130 may include a flexible material to enable a volume change of the accommodation space. In addition, the accommodating unit 130 may include a transparent material in order to check the amount of the fluid contained therein, and together with the accommodating unit 130, a ruler 139 may be provided to grasp the amount of the fluid contained in the accommodating space. Can be.

On the other hand, the drainage valve 118 may be installed in the receiving unit 130 so that the body fluid flows into the sealed receiving space.

The drain valve 118 may be an inlet through which body fluid flows from the receiving space. The drain valve 118 may be connected to one end of a drain tube (not shown) inserted into the affected part of the patient. In addition, the drain valve 118 may be provided with a one-way valve such as a check valve 190 for allowing the body fluid to flow in only one direction so that body fluid in the accommodation space does not flow back toward the affected part of the patient. According to the one-way valve, the body fluid can flow only in one direction from the affected part of the patient toward the receiving space.

According to the accommodation unit 130 and the drain valve 118 described above, the body fluid introduced into the accommodation space is difficult to be discharged to the outside. In some cases, it may be necessary to drain body fluids from the receiving space to the outside. In this case, the discharge unit 119 may be provided in the accommodation unit 130. The discharge part 119 may be provided with a one-way valve to allow the fluid flow only in the direction from the receiving space to the outside. Alternatively, a stopper 181 for opening and closing the discharge part 119 may be provided in the discharge part 119 instead of the one-way valve.

According to the accommodating unit 130 of the flexible material, the accommodating space may be hardly deformed so that the volume at the second time is larger than the volume at the first time. The frame unit 110 may be used as a means for achieving a volume change of the accommodation space.

The frame unit 110 may be inserted into the accommodation unit 130, specifically, the accommodation space. The frame unit 110 may be configured to deform from the first shape to the second shape. According to this, the accommodation space may also be modified in accordance with the shape deformation of the frame unit 110. Therefore, when the shape of the frame unit 110 is deformed in the direction in which the accommodation space is expanded, the volume of the accommodation space is increased in this process, and a sound pressure for sucking the body fluid may be formed. In addition, the frame unit 110 may also include a transparent material in order to prevent the view of being blocked by the frame unit 110.

In addition, the drain valve 118 and the discharge part 119 may be installed in the frame unit 110 through the receiving unit 130. Since the frame unit 110 has a higher rigidity than the flexible receiving unit 130, deformation due to external force may hardly occur. When the drain valve 118 and the discharge part 119 are installed in the frame unit 110, the flow path of the body fluid provided in the drain valve 118 and the discharge part 119 may be effectively prevented from being deformed by an external force. .

The elastic part 150 may be used to automatically deform the shape of the frame unit 110. The elastic part 150 may be installed in the frame unit 110 and may deform the shape of the frame unit 110. For example, the elastic unit 150 may include an elastic body such as a spring and a rubber band, and may deform the shape of the frame unit 110 by an elastic force.

Depending on the structure or configuration of the frame unit 110 and the elastic portion 150, the ease of use, storage and manufacturing convenience of the medical suction device may vary.

In order to improve convenience of use / storage / manufacturing, the elastic part 150 may be configured such that two points of the receiving unit 130 rotate relative to each other.

For example, the frame unit 110 may be connected to the reference unit 115 on which the drain valve 118 is installed, the first wing 111 connected to one side of the reference unit 115, and the other side of the reference unit 115. The second wing 112 may be provided.

In addition, at least one of the first wing 111 and the second wing 112 may be rotatably formed around the reference unit 115. At this time, the elastic portion 150 is provided over the first wing portion 111 and the second wing portion 112, the elastic force in the direction away from the first wing portion 111 and the second wing portion 112 to each other. Can provide.

According to this configuration, the frame unit 110 may be provided with a first wing portion 111 and the second wing portion 112 that is relatively rotated by the elastic portion 150.

Looking at the drawings, a flexible plate extending in the first direction (x-axis direction) may be provided. At this time, the flexible plate may be a receiving unit 130 having a receiving space for body fluids. In this case, the reference unit 115 may extend in a second direction (y-axis direction) perpendicular to the first direction. The first wing 111 and the second wing 112 may be disposed at different positions along the first direction with the reference portion 115 interposed therebetween. In this case, the first wing 111 may be rotated around the reference line i1 provided at one side of the reference unit 115 and extending in the second direction. The second wing 112 may be rotated around the reference line i2 provided on the other side of the reference unit 115 and extending in the second direction. When the reference part 115, the first wing part 111, and the second wing part 112 are integrally formed, the reference lines i1 and i2 may be portions formed in a thinner thickness compared to the reference part 115 and each wing part. have.

The elastic portion 150 preferably includes a torsion spring. This is because the torsion spring can provide an almost constant elastic force regardless of the rotation of the first wing portion and the second wing portion. According to this, the sound pressure generated by the receiving unit 130 may also be kept constant regardless of the shape deformation.

The torsion spring may have a shaft having a coil shape that is fitted to the rotation shaft 170 provided between the first wing 111 and the second wing 112. One end extending from the shaft may be installed on the first wing 111, and the other end extending from the shaft may be installed on the second wing 112.

One end and the other end of the torsion spring can be kept extending in the first direction as usual. The torsion spring may have an elastic force for rotating the first wing 111 and the second wing 112 in the reverse direction when the first wing 111 and the second wing 112 are rotated in the forward direction by an external force. Can provide.

The rotating shaft 170 to which the shaft of the torsion spring is fitted may be provided separately from the first wing 111, the second wing 112, and the reference unit 115, or may be provided in the reference unit 115. For example, FIG. 1 discloses a rotation shaft 170 integrally formed with the reference unit 115.

A locking jaw may be provided at the end of the rotation shaft 170 so that the torsion spring fitted to the rotation shaft 170 is not separated from the rotation shaft 170 by an external force.

In addition, the first wing 111 and the second wing 112 may be provided with a groove-shaped rib 113 into which one or the other end of the torsion spring is fitted. The rib 113 may extend along the first direction. According to this, one end or the other end of the torsion spring may be installed to be movable in the rib (113). If one end and the other end of the torsion spring are fixed to each wing, rotation of the first wing 111 and the second wing 112 may be limited. However, there is no such problem because one end and the other end of the torsion spring are installed to be movable along the rib 113 extending in the first direction. On the other hand, the torsion spring fitted to both ends of the rib may be limited in flow in the second direction by the rib. As a result, the ribs may limit some of the torsional screwing off the axis of rotation.

The accommodation unit 130 may include a transparent flexible material so that the state of the body fluid filled in the accommodation space or the amount of the body fluid can be checked from the outside. The frame unit 110 may be attached to the accommodating unit 130 through ultrasonic welding so as to reliably deform the accommodating space.

Therefore, if the frame unit 110 includes an opaque material, it may be difficult to check the body fluid filled in the accommodating space even though the transparent accommodating unit 130 is provided. In order to prevent the accommodation space from being blocked by the frame unit 110, a confirmation hole 117 may be formed in at least one of the first wing 111 and the second wing 112. According to the confirmation hole 117, a phenomenon in which the field of view is blocked by the frame unit 110 can be prevented.

In addition, the ruler 139 may be formed at a position facing the confirmation hole 117 in the accommodation unit 130 or around the confirmation hole 117 in the frame unit 110 as shown in FIG. 4 or 5. According to this configuration, it is possible to accurately grasp the amount of body fluid introduced into the accommodation space of the accommodation unit 130 using the confirmation hole 117 and the ruler 139.

If the ruler 139 is provided at a position where the shape is easily deformed, the ruler 139 may not function reliably due to the deformation of the shape. However, according to the present embodiment, even if the receiving unit 130 is flexible, the flexible parts attached to the respective wing portions maintain a flat state that is difficult to deform. According to this, the portion of the receiving unit 130 facing the confirmation hole 117 formed in the wing can also maintain a flat state that is not easily deformed by external force. Therefore, since the position of the ruler 139 is not changed by an external force, the amount of the body fluid can be accurately determined using the ruler 139.

On the other hand, the reference portion 115 to which the wings are connected to both sides may be provided with a drain valve 118 and a discharge part 119 for discharging the body fluid contained in the accommodation space to the outside. For convenience of manufacture, the first wing part 111, the second wing part 112, the reference part 115, the drain valve 118, and the discharge part 119 may be a mold formed integrally using a mold. However, the drain valve 118 may be provided with a check valve 190 to allow the external body fluid to flow into the accommodation space and to prevent the body fluid of the accommodation space from being discharged through the drain valve 118. At this time, since the check valve 190 has a complex structure in itself, it may be difficult to manufacture through the mold integrally with the drain valve 118 and the like. Therefore, the check valve 190 may be provided separately from the drain valve 118 and may be fastened to the drain valve 118 if necessary.

The check valve 190 may be formed in various ways. For example, the check valve 190 may be formed of a duck bill type similar to the inlet shape of the flute.

The reference part 115, the first wing part 111, and the second wing part 112 may be attached to the first surface ① of the plate-shaped accommodation unit 130 through ultrasonic welding or the like. At this time, the drain valve 118 installed in the reference unit 115 may protrude from the first surface ①. In addition, the check valve 190 may be installed by fitting the check valve 190 to the protruding drain valve 118.

Meanwhile, the drain valve 118 and the discharge part 119 may protrude to the outside through the reference part 115 and the receiving unit 130. In other words, the drain valve 118 and the discharge part 119 may protrude from the second surface ② corresponding to the opposite surface of the first surface ② in the receiving unit 130.

Figure 3 is another perspective view of a medical suction device of the present invention. The medical suction device illustrated in FIG. 3 may be an inverted medical suction device of FIG. 2.

Looking at it, it can be seen that the drain valve 118 connected to the reference unit 115 protrudes through the first hole 131 provided in the accommodation unit 130. In addition, it can be seen that the discharge part 119 also protrudes through the second hole 132 provided in the accommodation unit 130. Thus, the drain valve 118 protruding from the second surface ② can be easily installed drain pipe connected to the affected part of the patient. In addition, a stopper 181 for closing the drain hole may be easily installed in the drain hole protruding from the second surface ②. That is, a pipe or stopper 181 through which body fluid flows may be easily fitted into the drain valve 118 or the discharge part 119 protruding from the receiving unit 130.

The medical suction device of the present invention is preferably installed on an external support (not shown) rather than being carried by hand. At this time, the external support may be a garment, a belt, etc. worn by the patient. Or it may include a carrier, a bag, etc. that the patient is carrying or dragging. In order to be installed on the external support, the medical suction device may be provided with a connection unit 180.

The connection unit 180 may be provided with a connection portion 183 such as a connector or a forceps to be installed on an external support. At this time, in order to expand the utilization range of the connection unit 180, the connection portion 183 may be provided with a connecting ring 185, extension 187, plug 181.

The connection ring 185 may be installed at the end of the connection unit 183 to connect the connection unit 183 to the accommodation unit 130. In this case, the connecting ring 185 may be fitted to the drain valve 118 or the discharge part 119 protruding from the second surface ② of the accommodation unit 130.

Extension portion 187 is an element extending to one side from the connection portion 183 may be provided with a stopper 181 at the end.

The stopper 181 may close the discharge part 119 or close the drain valve 118 in which the drain pipe is not connected.

According to the connection unit 180 having such a structure, the connection function of the external support, the plug function, and the connection function with the reference part can be realized with one member.

Meanwhile, a stopper is provided at a portion protruding from the drain valve 118 and the discharge part 119 to the outside in order to prevent the connecting ring 185 fitted into the drain valve 118 or the discharge part 119 from being undesired. Can be. In addition, the connection ring 185 of the connection unit 180 may be fitted to the stopper.

1 to 3 may be folded so that one side and the other side of the first surface ① face each other with respect to the imaginary line o in the plate-shaped flexible plate material. Then, one side edge ⓐ of the first surface ① facing each other and the other side edge ⓐ of the first surface ① may be attached to each other to form a sealed accommodation space. In this case, the virtual line o may be the same as the rotation shaft 170 to which the elastic portion 150 is fitted.

The present invention is characterized in that the receiving space 130 is provided with a body fluid is accommodated, one side and the other side is formed to be relatively rotatable around the first hole 131 in which the body fluid is introduced. According to this, the receiving space can be deformed like an accordion or a bellows. In addition, if the connection unit 180 is installed at the side of the first hole 131, a phenomenon in which a feeling of wearing is deteriorated can be prevented even when the accommodation space is expanded compared to the cylindrical medical aspirator. For example, when one side provided with the first wing portion 111 is in contact with the patient, even if the receiving space is extended, the other side provided with the second wing portion 112 moves away from the first wing portion 111. There is no shape deformation. Therefore, the patient can feel comfortable wearing regardless of whether the accommodation space is expanded. In addition, if necessary, the operation of narrowing the gap between the ends of each wing without having to press the up and down of the accommodation unit 130 at the same time to overcome the elasticity of the elastic portion 150 and the first wing 111 and the second wing ( 112 may be in close contact with each other.

In addition, the present invention is characterized in that the frame unit 110 is installed in the accommodation space. In other words, the frame unit 110 may be installed on the inner surface of the accommodation unit 130. According to this, the portion exposed to the outside in the medical suction device may be limited to the receiving unit 130, the drain valve 118, the discharge portion 119. In the comparative embodiment in which the frame unit 110 is installed on the outer surface of the accommodating unit 130, clothing or the like is caught by the frame unit 110, or various foreign substances introduced from the outside are transferred to the frame unit 110 and the accommodating unit 130. ) Can be caught between. However, according to the present invention in which the frame unit 110 is installed in the accommodation space, such a problem can be prevented at the source.

However, in order for these features to appear as an advantage in the present invention, the problem of installing the frame unit 110 in the accommodation space should be solved. This is because it is difficult to install the frame unit 110 including the first wing 111 and the second wing 112 in a sealed space.

In order to solve this problem, the accommodation unit 130 of the present invention can be manufactured using a plate-shaped flexible plate.

For example, in the plate-shaped flexible plate, one side and the other side of the first surface ① may be folded to face each other with respect to the imaginary line o. Then, one side edge ⓐ of the first surface ① facing each other and the other side edge ⓐ of the first surface ① may be attached to each other to form a sealed accommodation space.

The frame unit 110 may be installed on the flexible plate before the first surface ① is folded and the edges ⓐ are attached to each other. Specifically, the first wing 111 and the second wing 112 may be installed on one side and the other side of the first surface facing each other. Accordingly, when forming the accommodation space, the first wing 111 and the second wing 112 may be naturally disposed in the accommodation space.

The elastic part 150 interposed between the first wing part 111 and the second wing part 112 may also be installed before the accommodation unit 130 is folded and the edge is attached.

The first wing 111 and the second wing 112 may rotate relative to the imaginary line o. Connecting the two between the first wing portion 111 and the second wing portion 112 so that the relative rotation of the first wing portion 111 and the second wing portion 112 centering on the pseudo line o The reference unit 115 may be used. In addition, the elastic part 150 may provide an elastic force in a direction away from the first wing 111 and the second wing 112.

According to this configuration, it is possible to install the frame unit 110 in the accommodation space and at the same time can be provided with a housing unit 130 that extends in a similar manner to the bellows on the basis of the virtual line o. When the drain valve 118 is installed in the reference unit 115 provided near the virtual line o, all of the above-described features of the present invention can be satisfied.

In order to fold the receiving unit 130 of FIG. 2 as shown in FIG. 4, an external force that overcomes the elastic force of the elastic unit 150 may be applied. When the external force is released in the folded state of the accommodating unit 130 as illustrated in FIG. 4, the accommodating unit 130 may be expanded as illustrated in FIG. 5 by the elastic force of the elastic unit 150.

4 is a perspective view showing a completed state of the medical suction device of the present invention, Figure 5 is a schematic diagram showing the operation of the medical suction device of the present invention.

The accommodating unit 130 of the present invention may be folded such that one side and the other side of the first surface ① are faced with respect to the virtual line o. According to this, the first wing portion 111 attached to one side of the first surface ① and the second wing portion 112 attached to the other side of the first surface ① may also be stacked in a state facing each other. In this state, when the elastic force of the elastic unit 150 acts due to the release of the external force, as shown in FIG. 5, the accommodation unit 130 may be expanded and the accommodation space may be expanded. In order to surround the expanded accommodation space, the area of the flexible plate constituting the accommodation unit 130 may be larger than that of the frame unit 110. In particular, in consideration of the accommodation unit 130 or the frame unit 110 that rotates around the virtual line o, the flexible plate is preferably wider from the virtual line o toward one side or the other side of the first surface ①.

According to this, the area of the flexible plate may be larger than the first wing portion and the second wing portion. In addition, when the first wing and the second wing is provided within the range of the flexible plate so as not to leave the flexible plate, the edges of the flexible plate in the folded state face each other despite the presence of the first wing and the second wing. Can be contacted.

In addition, since the width of the flexible plate increases from the center toward both sides, a margin for ensuring the rotation of the first wing portion and the second wing portion may be provided.

5, the first wing 111 and the second wing 112 are rotated relative to each other by the elastic part 150. According to this, the accommodation space is expanded, and the body fluid of the affected part may be sucked into the accommodation space by the negative pressure generated through the accommodation space. In FIG. 5, when the bottom face is a face facing the patient, the first wing part 111 whose flow is restricted by the patient is fixed and the second wing part 112 rotates in a direction away from the first wing part 111. . According to this, since the portion facing the patient is maintained as the portion facing the first wing 111 can be provided with a constant fit regardless of the period of use.

Hereinafter, look at the process of manufacturing a medical suction device of the present invention. The following process may correspond to the medical suction device manufacturing method of this invention.

6 to 11 is a schematic view showing a process for producing a medical suction device of the present invention. The present manufacturing process may be performed by a person or a manufacturing apparatus.

First, as shown in FIG. 6, a flexible plate having a plate shape extending in a first direction and a frame unit 110 are provided.

The flexible plate may have a larger area than the frame unit 110, and in particular, may be formed to be wider from both sides of the imaginary line o toward both sides when the flexible plate is folded about the imaginary line o. A first hole 131 through which the drain valve 118 penetrates and a second hole 132 through which the discharge part 119 penetrate may be provided at a position facing the virtual line o in the flexible plate.

The frame unit 110 may include a reference part 115, a first wing part 111, and a second wing part 112 and may be manufactured as an integral mold in a mold. The first wing 111 and the second wing 112 are formed in a plate shape, and may be attached to different positions along the first direction within the range of the first surface ①. At this time, it is preferable that ultrasonic welding is applied to smoothly attach the frame unit 110 and the flexible plate.

Next, as shown in FIG. 7, an elastic part 150 connected to the first wing part 111 and the second wing part 112 may be installed. For example, the installation of the elastic unit 150 may be to install a torsion spring on the rotating shaft 170 connected to the frame unit 110. The rotating shaft 170 may be integrally formed with the reference unit 115 provided in the frame unit 110. Of course, the rotating shaft 170 may be installed on the reference unit 115 in a state provided separately from the frame unit 110.

Both ends of the torsion spring fitted to the rotation shaft 170 may extend along the first direction. According to this, the torsion spring can be easily installed on the rotating shaft 170 even without applying an external force that overcomes the elastic force of the torsion spring.

In addition, as shown in Figure 8, both ends of the torsion spring may be installed on the ribs 113 provided in each wing. 9, the check valve 190 may be installed on the reference unit 115 or the flexible plate that connects the first wing 111 and the second wing 112 to each other.

In this case, the check valve 190 may be installed in the drain valve 118 at any stage of the process of FIGS. 6 to 9. The check valve 190 is configured to allow the movement of the body fluid in the direction from the second surface ② to the first surface ① of the flexible plate, and restrict the movement of the body fluid in the direction from the first surface ① to the second surface ②. Can be.

Next, as shown in FIG. 10, the flexible plate may be folded such that the first wing 111 and the second wing 112 face each other. To this end, an external force that overcomes the elastic force of the elastic part 150 may be applied to the first wing part 111 or the second wing part 112. In addition, when the first wing 111 and the second wing 112 face each other, that is, the first wing 111 and the second wing 112 are stacked, the first surface ① of the flexible plate 1. One edge ⓐ and the other edge ⓐ of the may face each other.

The edges ⓐ of the first surface ① facing each other can be attached to each other. The attachment of the edge ⓐ forms a closed receiving space from the outside, so the attachment is strongly made. Therefore, the attachment is preferably made by thermal fusion instead of ultrasonic attachment.

When the process of FIG. 10 is completed, an accommodation unit 130 having a sealed accommodation space may be formed. And, as shown in Figure 11 by inserting the connecting ring 185 of the connection unit 180 to the drain valve 118 and the stopper of the discharge portion 119 protruding from the receiving unit 130, all the process can be completed. have. The medical suction device thus completed has a plate shape which occupies a small space as a whole, and thus is easily stored. In addition, the medical suction device may be inserted into the restraining

portions

161, 162, and 163 of FIG. 11, such as a band for maintaining the plate shape, and the sound pressure may be formed by the elastic portion only by removing the restraining portion.

The restraining part can suppress the elastic force of the elastic part in a state where the first wing part and the second wing part are in close contact. The elastic force provided from the elastic part moves the first wing part and the second wing part in a direction away from each other. According to the restraining part that suppresses the elastic force, the first wing part and the second wing part can maintain the state facing close to each other. have. When the restraint part is released in this state, the first wing part and the second wing part can be rotated in a direction away from each other by the elastic force. Each of the wing parts rotated relative to each other increases the volume of the accommodation space of the accommodation unit, thereby creating a negative pressure for sucking external body fluid.

The restraining

portions

161, 162, and 163 may include at least one of a clip 161 surrounding the one surface and the other surface of the receiving unit together, a band 162 including a rubber material, and a Velcro 163. It is preferable that the restraint portion surrounds the region 설치된 provided with each wing portion at one side and the other side of the receiving unit. This is because the receiving unit itself is flexible, so it is good to wrap the wing corresponding to the frame unit supporting the receiving unit.

In actual use, a drain pipe connected to the affected part may be connected to the drain valve 118 in a state in which the outlet 119 is blocked by a stopper 181 connected to the connection unit 180. Of course, before the first wing 111 and the second wing 112 will be kept in a superimposed state as shown in FIG. When the external force, for example, a band or the like, that overlaps the first wing 111 and the second wing 112 is removed while the drainage pipe is connected, the first wing 111 by the elastic force of the elastic unit 150 is removed. The second wing 112 may rotate relative to the virtual line o. Then, the accommodation space is expanded by the relative rotation at this time, the body fluid of the affected part can be sucked into the accommodation space by the sound pressure generated thereby.

When the body fluid is filled in the accommodation space more than the set amount, the user who recognizes the fact through the confirmation hole can remove the stopper 181 blocking the discharge unit 119 and discharge the body fluid through the discharge unit 119.

According to the method for manufacturing a medical suction device described above, the frame unit 110 is installed inside the accommodation space using the plate-shaped flexible plate and the plate-shaped frame unit 110, and rotates around the virtual line o. Medical suction device can be easily manufactured.
