Description

[0001] SURGICAL DRAPE DISPENSER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical drape dispenser, and more particularly, to a surgical drape dispenser capable of easily attaching a surgical drape to a surgical site of a patient.

Surgical drape is used to attach to the incision site of the patient when performing incision surgery such as open surgery, denture surgery, or open thoracotomy.

The primary purpose of using a surgical drape is to facilitate the display of the incision site with a pen or the like during surgery, to prevent infection of the incision site, to prevent biological contaminants such as blood and body fluids flowing out of the incision site from propagating to other sites . The surgical drape is usually removed before the incision is closed after the operation is completed.

At present, a film-like surgical drape that does not allow the biological contaminants to pass through is used, and an adhesive surface is formed on one surface of the drape so that the adhesive drape can be attached to the skin of the patient.

However, since such a surgical drape is a flexible and stretchable film made of a material such as polyurethane or polyethylene, the drape is partially wrinkled during the process of removing the release paper adhered to the adhesive surface or attaching to the surgical site of the patient Or more frequently occurs.

In order to prevent this, there is a disadvantage that a large number of personnel hold the surgical drape and attach it to the surgical site of the patient with a uniform force, and care must be taken when removing the release paper.

In order to solve this problem, Korean Utility Model Registration No. 20-0451650 (hereinafter referred to as "Patent Document 1") discloses a method in which a reinforcement film is further attached to the other surface of an adhesive film having a release paper on one surface thereof, A surgical drape is provided.

Supporting protrusions 145, 146, 155 and 156 are formed on the outer circumferential surfaces of the rotating shafts 141, 142, 151 and 152.

The support protrusions 145, 146, 155 and 156 are arranged such that the pair of support frames 140 and 150 rotatably support the feed roller 110 and the collection roller 120, . This will be described with reference to FIG.

Fig. 3 is a view showing a part of a longitudinal section of the surgical drape dispenser 100 shown in Fig.

3, a hollow portion 111 into which the rotation shaft 141 is inserted is formed at one end of the supply roller 110, and a hollow portion (not shown) through which the rotation shaft 142 is inserted is also formed at one end of the recovery roller 120 121 are formed.

The inner circumferential surface of the hollow portion 111 is formed with a support groove 113 into which the support protrusion 145 is inserted and a support groove 123 through which the support protrusion 146 is inserted is formed on the inner circumferential surface of the hollow portion 121.

One end of the feeding roller 110 and one end of the collecting roller 120 can be arbitrarily selected from the rotating shafts 141 and 142 coupled to the respective ones by the engagement of the supporting grooves 113 and 123 and the supporting protrusions 145 and 146 It may not be separated.

The other end of the feed roller 110, the other end of the rotation shaft 151 and the recovery roller 120, and the rotation shaft 152 have the above-described coupling structure.

However, the structure in which the pair of support frames 140 and 150 described above supports the feed roller 110 and the collecting roller 120 in a rotatable manner, as one example, may be changed in various ways It is self-evident.

The guard ribs 143 and 153 are engaged with the gears 131, 131a, 132 and 132a from the outer periphery of the support frame 140 in order to prevent the user's hands, clothes, etc. from being caught in the gears 131, 131a, 132 and 132a As shown in Fig. Therefore, the protruded length of the guard ribs 143 and 153 may be longer than the width of the gears 131, 131a, 132 and 132a.

1 and 2, the surgical drape 160 is provided with an adhesive sheet 161 on which a pressure-sensitive adhesive is applied to one surface of a flexible film made of a material such as polyethylene or polyurethane to form an adhesive surface 162, (163).

The surgical drape 160 is kept wrapped around the feed roller 110 before use and has a shape that begins to be wound around the outer circumferential surface of the feed roller 110 from one end (not shown) of the surgical drape 160 .

More specifically, the other surface of the adhesive sheet 161 at one end of the surgical drape 160 is disposed on the outer circumferential surface of the feeding roller 110. At this time, in the outer circumferential surface of the feeding roller 110, As shown in Fig.

Next, the feeding roller 110 is rotated in the direction indicated by W1 in Fig. 2 so that the surgical drape 160 is wound on the outer peripheral surface of the feeding roller 110. [

Therefore, as shown in the drawing, the surgical drape 160 has a shape in which the portion of the surgical drape 160 that starts to be wound or unwound from the outer peripheral surface of the feeding roller 110 is disposed in the direction toward the collecting roller 120, The releasing paper 163 is disposed to face the collecting roller 120.

On the other hand, the pull-out bar 170 is engaged with the other end of the adhesive sheet 161 in the other end of the surgical drape 160. The drawing bar 170 can be formed by a method of joining the other end of the adhesive sheet 161 interposed between bars having a semicircular cross section of a pair of the pair of curled portions 170a and 170b as shown in Fig. have.

Alternatively, although not shown, the pull-out bar 170 may be fixedly coupled to the outer surface of the rod-shaped member by a method such as adhesion or fusing.

At this time, the pull-out bar 170 may be disposed in parallel with the feed roller 110 or the collecting roller 120 so that the surgical drape 160 is prevented from being wrinkled or partially stretched.

2, the rotating means 190 is shown.

The rotating means 190 is provided with a winding protrusion 191 and the rotating means 190 is formed so as to be inserted into the through hole 144.

2 and 3, the through hole 144 is formed so as to be in communication with the hollow portion 111 of the supply roller 110. In the hollow portion 111, a take-up rib 115 protrudes.

The take-up ribs 115 have a shape corresponding to that of the take-up protrusions 119. Therefore, when the rotating means 190 is inserted into the through hole 144 so that the winding projection 119 and the winding rib 115 are engaged with each other, the rotating means 190 is rotated in the direction of W1 shown in FIG. 2, The drape 160 is wound around the outer peripheral surface of the feeding roller 110, and the drawing bar 170 is moved in the direction indicated by A.

After the surgical drape 160 is sufficiently wound around the outer circumferential surface of the feeding roller 110, the rotating means 190 is pulled out of the through hole 144. That is, the rotating unit 190 is a kind of tool for easily winding the surgical drape 160 on the outer peripheral surface of the feeding roller 110.

Meanwhile, when the surgical drape 160 is completely wound on the surface of the feeding roller 110, the drawing-out bar 170 is also brought into close contact with the surface of the feeding roller 110, making it difficult to pull out the drawing-out bar 170 .

In order to prevent this, the length L2 of the withdrawal bar 170 may be formed to be equal to or longer than the distance L1 between the pair of support frames 140 and 150.

Thus, when the surgical drape 160 is sufficiently wound on the feeding roller 110, the both ends of the pull-out bar 170 are brought into contact with the outer circumferences of the pair of support frames 140 and 150, respectively, It becomes a figure.

FIG. 4 illustrates a state in which a surgical drape dispenser 100 according to an embodiment of the present invention is packaged in a package 101.

Referring to FIG. 4, the package 101 packaging the completed surgical drape dispenser 100 is a gamma-ray sterilization sealed package. Since the surgical drape dispenser 100 is used in the operating room, will be.

2 and 4 together, as the surgical drape 160 is wound around the outer circumferential surface of the feeding roller 110, the withdrawing bar 170 is moved in the A direction so that both ends of the withdrawing bar 170 are held in the supporting frame The back surface of the surface of the releasing paper 163 facing the adhesive surface 162 of both ends of the release paper 163 is bonded to the outer circumferential surface of the recovery roller 120 by a method such as adhesion or bonding.

At this time, a portion to which the back surface of the release paper 163 is coupled corresponds to a portion of the outer circumferential surface of the collection roller 120 that faces the supply roller 110, and after the coupling, the shape shown in FIG.

Meanwhile, the drape dispenser 100 may be shaken or impacted in the process of being accommodated in the package 101. When the pull-out bar 170 relatively moves relative to the pair of support frames 140 and 150 due to such shaking or impact, the surgical drape 160 wound on the feed roller 110 can be loosened.

In order to prevent this, the completed surgical drape dispenser 100 may allow the pull-out bar 170 to be seated at a predetermined position of the pair of support frames 140 and 150.

That is, both the end portions of the drawer bar 170 can be seated so that the seating grooves 148 and 158 are formed in the pair of the support frames 140 and 150, respectively. The seating grooves 148 and 158 may be formed in a shape corresponding to the outer circumferential surface of the draw bar 170 so that at least a portion of the draw bar 170 may be received in the seating grooves 148 and 158.

Alternatively, the surgical drape dispenser 100 may further include fixing means for detachably fixing both ends of the drawing bar 170 to the pair of supporting frames 140 and 150.

Examples of such fixing means include the permanent magnets 181 and 181a and the ferromagnetic bodies 182 and 182a shown in Fig.

Referring again to FIG. 1, permanent magnets 181 and 181a are respectively installed on the pair of support frames 140 and 150, and ferromagnetic members 182 and 182a are provided on both ends of the withdrawal bar 170.

4, attraction forces are applied to the ferromagnetic bodies 182 and 182a by the magnetic forces of the permanent magnets 181 and 181a when both ends of the withdrawing bar 170 are supported by the support frames 140 and 150, Both ends of the drawing bar 170 are detachably fixed to the pair of supporting frames 140 and 150.

As shown in the drawing, when the permanent magnets 181 and 181a and the ferromagnetic bodies 182 and 182a together with the seating grooves 148 and 158 are used together, the withdrawing bar 170 is supported by the pair of supporting frames 140 and 150 It is possible to maintain a stable seating state.

5 is a cross-sectional view taken along the line V-V shown in Fig.

Referring to FIGS. 4 and 5, the operation of the surgical drape dispenser 100 will be described below.

When attaching the adhesive sheet (see 161 in FIG. 1) included in the surgical drape 160 to the patient's skin in the operating room, the package 101 is opened and the surgical drape dispenser 100 is taken out.

After one person holds the pair of support frames 140 and 150 with both hands and the other holds both ends of the withdrawal bar 170, the pair of support frames 140, 150 to move the pull-out bar 170.

At this time, as the pull-out bar 170 moves, the feeding roller 110 is rotated in the direction indicated by W2, and the surgical drape 160 wound on the outer peripheral surface of the feeding roller 110 is released. At this time, the collection roller 120 is rotated in the opposite direction W3 to the feeding roller 110, so that the release paper 163 is separated from the adhesive sheet 161 and wound on the outer peripheral surface of the collection roller 120. [

Therefore, the adhesive sheet 161 and the release paper 163 can be automatically separated only by pulling out the withdrawing bar 170, and the pressure sensitive adhesive sheet 161 can be uniformly tensioned at its ends by the withdrawing bar 170 So that it is partially withdrawn without wrinkling or elongation.

After the adhesive sheet 161 has been drawn to a length suitable for adhering to the patient's skin, the person holding the both ends of the drawer bar 170 and the person holding the pair of supporting frames 140 and 150, The pulling bar 170 and the pair of support frames 140 and 150 are moved so that the adhesive sheet 161 is adhered to the skin portion of the desired patient.

After the adhesive sheet 161 is adhered, one side and the other side of the adhesive sheet 161 are cut with a cutting tool such as scissors to complete the attaching operation of the adhesive sheet 161. [

At this time, when a safety knife or the like capable of safely cutting the adhesive sheet 161 is attached by the magnetic forces of the permanent magnets 181 and 181a provided on the pair of support frames 140 and 150, the usability can be further improved have.

As described above, the surgical drape dispenser 100 according to an embodiment of the present invention can easily attach the adhesive sheet of the surgical drape 160 to the patient's skin even with a small force.

The number of manpower required is determined according to the distance between the pair of support frames 140 and 150 (L1 in FIG. 2) according to the width of the surgical drape 160 It can be different.

If the width of the surgical drape 160 is small, it is possible to perform the above work with a single human force.

When the length L2 of the withdrawing bar 170 is longer than the distance L1 between the pair of supporting frames 140 and 150 as described above, It becomes easy.

Although not shown, the pair of support frames 140 and 150 may be provided with handles that can be easily hand-held, or may be formed to protrude, so that the use of the surgical drape 160 may be facilitated.

Since many electronic equipments are used in the operating room at present, the magnetic forces of the permanent magnets 181 and 181a may cause malfunction of the equipments provided in the operating room. Therefore, other fixing means may be used instead of the permanent magnets 181 and 181a as fixing means in a place where the magnetic force generating material should be strictly restricted.

For example, although not shown, the arm barrel may be provided on one of the draw bar 170 and the pair of support frames 140 and 150, the male velcro may be provided on the other side, A fixing protrusion may be formed on one of the pair of support frames 140 and 150 and a fixing groove may be formed on the other of the support frames 140 and 150 to correspond to the fixing protrusion.

The pull bar 170 may be detachably coupled to the pair of support frames 140 and 150 by applying an adhesive to one of the pull bar 170 and the pair of support frames 140 and 150 .

The direction indicator 149 mentioned above indicates the direction of the adhesive surface 162 formed on the adhesive sheet 161. [

That is, when both sides of the adhesive sheet 161 are of the same color, it is possible to confuse which side of the adhesive sheet 161 is the adhesive surface 162. Therefore, any one of the pair of the support frames 140, The direction indicator 149 indicating the direction of the adhesive surface 162 as shown in FIG. 1 can be formed in all.

6 and 7 are exploded perspective views of a surgical drape dispenser 200 according to another embodiment of the present invention.

6 and 7, a surgical drape dispenser 200 according to another exemplary embodiment of the present invention includes a feeding roller 210, a collecting roller 220, a driving unit 230, support frames 240 and 250, A surgical drape 260, a withdrawal bar 270, and a pull handle 280.

A pair of support frames 240 and 250 are coupled to both ends of the supply roller 210 and the collecting roller 220, respectively. At this time, the pair of support frames 240 and 250 rotatably support both ends of the feed roller 210 and the collecting roller 220, respectively.

For this, a pair of rotation shafts 241, 242, 251 and 252 are protruded from the pair of support frames 240 and 250, respectively, as illustrated in the figure.

On the other hand, the feeding roller 210 and the collecting roller 220 are provided with the driving means 230 so that the feeding roller 210 and the collecting roller 220 are rotated in opposite directions to each other. Two pairs of gears 231, 231a, 232 and 232a provided at both ends of the feeding roller 210 and the collecting roller 220 may be used as the driving means 230. [

The transmission means 230 may be constituted only by a pair of gears 231 and 232 provided on one side of the feed roller 210 and the collecting roller 220 or by a pair of gears 231a and 232a ).

The gears 231 and 232 provided on one side of the feeding roller 210 and the collecting roller 220 and the gears 231a and 232a provided on the other side are connected to the pair of supporting frames 240 and 250 ), They are engaged with each other. Therefore, the feeding roller 210 and the collecting roller 220 are rotated in opposite directions to each other.

Guard ribs 243 and 253 and through holes 244 and 245 may be formed in the pair of support frames 240 and 250 in addition to the rotation shafts 241, 242, 251 and 252 described above.

The supply roller 210 is formed with a hollow portion 211 into which the rotating shafts 241 and 251 are inserted and a hollow portion 221 through which the rotating shafts 242 and 252 are inserted is formed in the collecting roller 220. The inner diameters of the hollow portions 211 and 221 are formed to be slightly larger than the outer diameters of the rotating shafts 241 and 242 and 251 and 252 so that the feeding roller 210 and the collecting roller 220 Can be smoothly rotated.

The structure in which the pair of support frames 240 and 250 support the feed roller 210 and the collection roller 220 in a rotatable manner can be changed in various ways as an example. It is self-evident.

For example, although not shown, a rotary shaft may be formed to protrude from both ends of the feed roller 210 and the collecting roller 220, May be formed.

Meanwhile, since the guard ribs 243 and 253 have the same function and effect as those of the guard ribs 143 and 153 described above, their overlapping descriptions are omitted.

The surgical drape 260 includes an adhesive sheet 261 and a release paper 263 having an adhesive surface 262 formed on one side of the flexible film like the surgical drape 160 described above. Here, the adhesive surface 262 may be formed by applying a pressure sensitive adhesive for human body to one surface of the adhesive sheet 261.

For reference, the pressure sensitive adhesive for the human body applied to the adhesive sheet 261 includes iodine, acrinol, silver nanoparticles, and the like in order to prevent infection at the surgical site and to have a sanitizing effect, May be included.

The surgical drape 260 is wound around the feeding roller 210 before use and has a shape in which one side of the surgical drape 260 is wound around the outer peripheral surface of the feeding roller 210.

More specifically, the other side of the adhesive sheet 261 in the one end of the surgical drape 260 is disposed in the direction toward the outer peripheral surface of the feeding roller 210, and then the portion of the surgical drape 260 except for the other end To be wound on the feed roller 210. [

As shown in the drawing, the surgical drape 260 allows the portion of the surgical drape 260 to start winding or unwinding from the outer peripheral surface of the feeding roller 210 to be disposed in the direction toward the collecting roller 220. That is, as shown in the drawing, the other side of the surgical drape 260 is disposed within the space formed between the feeding roller 210 and the collecting roller 220.

On the other hand, the other end of the surgical drape 260 separates the adhesive sheet 261 from the release sheet 263, and the outgoing bar 270 is coupled to the other end of the adhesive sheet 261.

The withdrawal bar 270 may have a straight bar shape and may consist of rods 271, 272 having a pair of semicircular cross-sections as shown. The other end of the adhesive sheet 261 is engaged with the outgoing bar 270 by engaging the other end of the adhesive sheet 261 between the two ends 271 and 272, can do.

Alternatively, although not shown, the pull-out bar 270 may be fixedly coupled to the outer surface of the rod-shaped member by an adhesive or fusion bonding method.

At this time, the pull-out bar 270 may be disposed in parallel with the feed roller 210 or the collecting roller 220 to prevent wrinkles or partial stretching of the surgical drape 260.

For reference, the length of the draw bar 270 may be equal to or longer than the distance between the pair of support frames 240 and 250. Accordingly, the drape dispenser 200 prior to use can be placed in contact with the outer circumferences of the pair of support frames 240, 250 at both ends of the drawer bar 270, have.

The releasing paper 263 separated from the pressure sensitive adhesive sheet 261 at the other end of the surgical drape 260 is joined to the outer circumferential surface of the collecting roller 220 as indicated by C in FIG. The back surface of the release paper 263 in the direction toward the adhesive surface 262 faces the outer peripheral surface of the recovery roller 220 and the peripheral surface of the release paper 263 and the recovery roller 220 are bonded to each other, To be fixedly coupled to each other.

The pull handle 280 may comprise a handle body 281, a pair of connecting ribs 282 and 283 and a pair of connecting protrusions 284 and 285.

The handle body 281 is formed into a bar shape as shown in the figure. One end of the connection ribs 282 and 283 is connected to both ends of the handle body 281 and the other end of the connection ribs 282 and 283 is connected to the pair of support frames 240 and 250 respectively.

At this time, as shown in the figure, the connecting protrusions 284 and 285 protrude from the other ends of the connecting ribs 282 and 283 in a direction facing each other. The pair of connecting protrusions 284 and 285 are formed by a pair of Are inserted into the through holes 245 (one of which is not shown) formed in the support frames 240 and 250, respectively.

For reference, the support frame 240 is formed with a through hole 244 passing through the rotation shaft 241. 2), which is in communication with the hollow portion 211 of the feed roller 210 and can rotate the feed roller 210 into the hollow portion 211 through the through hole 244, 190), so that the surgical drape 260 can be wound on the surface of the feeding roller 210.

The support frame 240 may have a through hole 245 passing through the rotation axis 242 for lightening the support frame 240.

Although not shown, a through hole is formed in the support frame 250 in the same manner as the through holes 244 and 245 described above.

The coupling protrusion 284 may be rotatably inserted into one of the through holes 244 and 245 of the support frame 240. The coupling protrusion 285 may also be inserted into the through hole formed in the support frame 250 As shown in Fig.

The traction handle 280 can thus be pivotally connected to the support frames 240 and 250 and spaced between the handle body 281 and the support frames 240 and 250 by the coupling ribs 282 and 283 So that the user can easily grip the knob body 281. [

The handle main body 281, the connecting ribs 282 and 283 and the connecting protrusions 284 and 285 constituting the pulling handle 280 can be integrally formed and made of a material having elasticity.

Therefore, when the pull handle 280 is resiliently deformed so that the distance between the pair of the coupling protrusions 284 and 285 is distanced, it is allowed to engage with the pair of the support frames 240 and 250, And 250 may be resiliently supported by the pull handle 280 so that the distance therebetween is not distanced.

The pair of support frames 240 and 250 can be prevented from being arbitrarily disengaged from the feed roller 210 and the collection roller 220 by the pull handle 280. [

The rotation shafts 241, 242, 251, and 252 formed on the support frames 240 and 250 of the surgical drape dispenser 200 according to another embodiment of the present invention include the rotation shafts The support frames 240 and 250 can be prevented from being arbitrarily disengaged without the support protrusions 145, 146, 155, and 156 formed in the protrusions 141, 142, 151,

Therefore, another embodiment 200 of the present invention can achieve an effect of simplifying manufacturing compared to the embodiment 100. [

On the other hand, although not shown, the pull handle 280 can be deformed into various shapes according to needs such as manufacturing convenience or allowing the user to grasp it more easily.

For example, the overall shape of the traction handle 280 may be arcuate or semicircular. Alternatively, a grip portion which can be easily held by hand in a direction opposite to the connecting ribs 282 and 283 may be formed in the middle portion of the pulling handle 280. [

The connection ribs 282 and 283 are fixedly coupled to the support frames 240 and 250 without the connection protrusions 284 and 285 being formed so that the user grips the handle body 281 with one hand The entire drape dispenser 200 can be easily moved in a desired direction.

FIG. 8 illustrates a state in which a surgical drape dispenser 200 according to another embodiment of the present invention is packaged in a package 201. FIG. 9 illustrates an operation state of the present embodiment 200, 10 is a cross-sectional view taken along the line X-X shown in Fig.

Referring to FIG. 8, the package 201 packaging the completed surgical drape dispenser 200 is a sealed package for gamma sterilization. Since the surgical drape dispenser 200 is used in the operating room, It is.

Accordingly, in the case of using the surgical drape dispenser 200 in the operating room (not shown), the package 201 is cut and the surgical drape dispenser 200 is taken out. Then, The adhesive drape 260 is released from the feeding roller 210 by applying a force to move the handle 280 and the drawer bar 270 in a direction to move them away from each other so that the adhesive sheet 261 can be unfolded have.

9 and 10, when the adhesive sheet 261 included in the surgical drape 260 is to be attached to the patient's skin in the operating room as described above, the package 201 is opened, The dispenser 200 is taken out.

Thereafter, when the force is applied in a direction in which the support frames 240 and 250 and the withdrawing bar 270 are moved away from each other by holding the withdrawing bar 270 and the pulling handle 280, The sheet 261 is pulled out.

That is, when the pulling handle 281 is pulled in the direction indicated by D and the pulling bar 270 is pulled in the direction indicated by E, the pulling force of the pulling knob 281 causes the feed roller 210 to move to the support frames 240 and 250 So that the surgical drape 260 wound on the outer circumferential surface of the feeding roller 210 is loosened.

The release roller 220 is rotated in the opposite direction W5 to the feed roller 210 by the gears 231a and 232a included in the transmission means 230 so that the release paper 263 is pressed against the adhesive sheet 261, And is wound on the outer circumferential surface of the collection roller 220.

Therefore, the adhesive sheet 261 and the release paper 263 can be automatically separated only by pulling out the withdrawing bar 270, and the adhesive sheet 261 is prevented from being pulled out by the withdrawing bar 270 in a uniform tensile force So that it is partially withdrawn without wrinkling or elongation.

After the adhesive sheet 261 has been drawn out from the embodiment 200 to a length suitable for adhering to the skin of the patient, the adhesive sheet 262 is pulled out of the drawer bar 270 and the pulling handle 280 are moved so that the adhesive surface 262 of the adhesive sheet 261 is adhered to the skin of the patient.

After the adhesive sheet 261 is adhered, one side and the other side of the adhesive sheet 261 are cut with a cutting tool such as scissors to complete the attaching operation of the adhesive sheet 261.

As described above, the surgical drape dispenser 200 according to an embodiment of the present invention can easily attach the adhesive sheet of the surgical drape 260 to the patient's skin even with a small force.

When the length of the adhesive sheet 261 to be attached to the patient's skin is not excessively long, the user holds the pulling handle 280 with one hand and holds the pulling bar 270 with the other hand, The manpower required for the operation for attaching the surgical drape 260 can be minimized.

For reference, the direction denoted by D and the direction denoted by E may be changed in directions different from those shown as necessary.

When the traction handle 280 is pivotally connected to the pair of support frames 240 and 250 as described above, the traction handle 280 is supported by the support frames 240 and 250 according to the direction in which the pulling force acts. The direction indicated by D and the direction indicated by E can be opposite to each other.

There is a difference between the linear velocity LV1 at which the surgical drape 260 is released from the outer peripheral surface of the feeding roller 210 and the linear velocity LV2 at which the releasing sheet 263 is wound around the outer peripheral surface of the collecting roller 220 . As the lead-out length of the surgical drape 260 becomes longer due to this difference, the state in which the release sheet is wound around the collection roller 220 may become poor.

That is, the thickness of the surgical drape 260 and the thickness of the release paper 263 differ by the thickness of the adhesive sheet 261. Therefore, when the rotation speed of the supply roller 210 is equal to the rotation speed of the collection roller 220 and the diameters R1 and R2 of the two rollers are equal to each other, the surgical drape 260 is released from the supply roller 210 And the length of the release paper 263 wound around the recovery roller 220 is different.

The difference is further increased according to the amount of the surgical drape 260 wound around the feeding roller 210. [

The amount of the surgical drape 260 wound on the feeding roller 260 gradually decreases as the surgical drape 260 is released from the feeding roller 210 but the amount of the release paper 263 wound on the collecting roller 220 It gradually increases.

The difference between the two linear velocities LV1 and LV2 thus varies continuously as the surgical drape 260 is withdrawn from the present embodiment 200 resulting in the release roller 220 having a release paper 263 The winding condition also changes continuously.

If the release paper 263 is wound on the collection roller 220 at a significantly slower rate than the release rate of the surgical drape 260 from the supply roller 210, The point at which the release paper 263 is separated from the adhesive sheet 261 is gradually moved in the direction in which the surgical drape 260 is pulled.

In this case, when the surgical drape 260 is pulled out by a required length from the embodiment 200, the release paper 263 is not yet separated in a part of the adhesive sheet 261, May occur.

To solve this problem, it is possible to adjust the outer diameter R1 of the feeding roller 210, the outer diameter R2 of the collecting roller 220, the gear ratio between the gears 231a and 232a, and the like.

For example, when the outer diameters R1 and R2 of the two rollers 210 and 220 are the same and the shapes of the gears 231a and 232a are the same, the diameter of the collection roller 220 is smaller than the outer diameter R1 of the supply roller 210, The outer diameter R2 of the outer circumferential surface can be made larger.

More specifically, when the shapes of the gears 231a and 232a are the same, the feeding roller 210 and the collecting roller 220 are rotated at the same angular velocity but opposite in direction.

When the two rollers 210 and 220 are rotated at the same angular velocity, the linear velocity LV1 at which the surgical drape 260 is released from the feeding roller 210 in which the surgical drape 260 is wound several times, Is smaller than the linear velocity LV2 at which the release paper 263 begins to be wound on the roller 220. [

If the outer diameter R2 of the collection roller 220 is formed to be larger than the outer diameter R1 of the supply roller 210 in consideration of the difference between the linear speeds LV1 and LV2, the two linear speeds LV1 and LV2 The state in which the release paper 263 is wound on the collection roller 220 can be made uniform.

If the outer diameters R1 and R2 of the two rollers 210 and 220 are the same, the gear ratio between the gears 231a and 232a can be adjusted.

For example, when the outer diameter of the gear 231a provided on the feeding roller 210 is larger than the outer diameter of the gear 232a provided on the collecting roller 220, that is, when the number of teeth of the gear 231a is equal to the number of teeth The difference between the two linear velocities LV1 and LV2 is reduced by increasing the rotation speed of the collection roller 220 relative to the feeding roller 210 so that the state in which the release paper 263 is wound on the collection roller 220 Can be improved.

Although not shown, if the friction wheels are used instead of the gears 231a and 232a, if the diameter of the friction wheels provided on the feed roller 210 is larger than the diameter of the friction wheels provided on the recovery roller 220, have.

Since the number of teeth of the gears 231a and 232a is an integer, it may be difficult to fine-tune the linear velocities LV1 and LV2 according to these differences. Therefore, the outer diameter of the gears 231a, 232a and the friction roller (not shown) provided on the supply roller 210 is made larger than the outer diameter of the gears provided on the collection roller 220 by combining the above- The outer diameter R2 of the collection roller 220 may be larger than or equal to the outer diameter R1 of the supply roller 210. [

Figs. 13 to 15 are views for explaining another example of the transmission means applied to the present embodiment 200. Fig.

13, another example of the transmission means includes an electric wheel 331 provided at the end of the supply roller 310, an electric wheel 332 provided at the end of the collection roller 320, and a motorized strap 337 .

The supply roller 310 has a hollow portion 311 corresponding to the rotation axis 241 of the support frame 240 and a hollow portion corresponding to the rotation axis 242 of the support frame 240 321 are formed.

Here, the feed roller 310 and the collecting roller 320 have the same construction as those of the feed roller 210 and the collecting roller 220 described above for the sake of convenience of description.

Although not shown, it is assumed that the above-described surgical drape 260 is coupled to the feeding roller 210 and the collecting roller 220 in the same manner as the feeding roller 210 and the collecting roller 220 .

The other end of the electric strap 337 is wound on the outer circumferential surface of the electric wheel 331 provided on the supply roller 310 and the other end of the electric strap 337 is wound around the electric wheel 332 As shown in Fig.

At this time, the direction in which the electric wheel 331 is wound around the outer peripheral surface of the electric strap 337 is the same as the direction in which the surgical drape 260 is wound around the feeding roller 310. The direction in which the other end of the electric strap 337 is attached to the electric wheel 332 is the same as the direction in which the other end of the middle release paper 263 of the surgical drape 260 is coupled to the collection roller 320.

14, after the feeding roller 310 and the collecting roller 320 are rotatably connected to the support frame 240, the surgical drape 260 is released from the supplying roller 310. As shown in FIG. The electric wheel 331 provided on the supply roller 310 is rotated in the direction indicated by W6.

At this time, the electric wheel 332 provided on the collecting roller 320 is rotated in the direction indicated by W7, which is opposite to the electric wheel 331 provided on the supplying roller 310. [

To this end, the outer periphery of the electric wheel 331 in a state in which the electric strap 337 is wound and the outer periphery of the electric wheel 332 in a state in which the electric strap 337 starts to be wound are arranged so as to be in contact with each other, The frictional force by the electric strap 337 can be applied.

That is, the distance DO between the rotation center O3 of the electric wheel 331 provided on the supply roller 310 and the rotation center O4 of the electric wheel 332 installed on the collection roller 320 is larger than the distance Half of the outer diameter R3 including up to half the outer diameter R3 including the thickness of the electric strap 337 wound on the electric wheel 331 and the thickness of the electric strap 337 wrapped around the electric wheel 332 can do.

With this configuration, when the surgical drape 260 wound on the feeding roller 310 is released, the electric wheel 331 is rotated in the direction indicated by W6, so that the electric wheel 332 is rotated in the direction indicated by W7 So that the collecting roller 320 is rotated in the direction opposite to the feeding roller 310.

The surgical drape 260 wound on the feeding roller 310 is released and the draining paper 263 is wound from the feeding roller 310 to the surgical drape 260 The speed at which the release paper 263 is wound by the recovery roller 320 is gradually increased.

15, as the electric wheel 331 is rotated in the direction indicated by W6, the electric strap 337 is rotated by the electric wheel 332 rotated in the direction indicated by W7 from the outer peripheral surface of the electric wheel 331, As shown in Fig.

Therefore, the outer diameter including the thickness of the electric strap 337 wrapped around the electric wheel 331 is reduced from R 3 to R 5 shown in FIG. 15, while the outer diameter including the thickness of the electric strap 337 wrapped around the electric wheel 332 The outer diameter is increased from R4 shown in Fig. 14 to R6 shown in Fig.

The distance DO between the rotational center O3 of the electric wheel 331 and the rotational center O4 of the electric wheel 332 is kept constant.

Therefore, as the surgical drape 260 is released from the feeding roller 310, the speed at which the release paper sheet 263 is wound on the collection roller 320 and the speed at which the surgical drape 260 is relatively loosened from the feeding roller 310 The change between the outgoing speeds can be minimized as the motorized strap 337 is moved between the drive wheels 331 and 332 as described with reference to Figs. 14 and 15.

That is, in the process in which the surgical drape 260 is released from the feeding roller 310 by the above-described operation between the two driving wheels 331 and 332 and the motorized strap 337, 320 is minimized, so that the release paper 263 can be wound around the feed roller 310 in a uniform state.

For this purpose, the thickness of the electric strap 337 may be formed to correspond to the thickness of the surgical drape 260. In addition, the electric strap 337 may have flexibility, but may be manufactured to have low elasticity due to tensile force and low compressibility due to pressure. Examples of such material include synthetic resin used for manufacturing interior trim plates.

Meanwhile, the present embodiment 200 may further include a reverse rotation preventing means. Here, the reverse rotation preventing means refers to the means for preventing the feeding roller 210 from rotating in the direction in which the surgical drape 260 is unlocked with respect to the support frame 240, 250, and not rotating in the opposite direction .

In the process of pulling out the surgical drape 260 using the present embodiment 200, it may happen that the required length of the adhesive sheet 261 can not be drawn out at a time. That is, while drawing out the surgical drape 260 up to the length of the adhesive sheet 261 which is finally required, the withdrawal of a number of times may be stopped and then taken out again.

In this process, the tensile force applied to the surgical drape 260 may be released or re-applied, or the magnitude of the tensile force may be varied. Accordingly, when the feeding roller 210 is slightly rotated counterclockwise, the release paper 263 can be repeatedly adhered and separated to a part of the adhesive surface 262, and deformation of the adhesive sheet 261 Lt; / RTI >

Therefore, it is necessary to prevent the feed roller 210 from being reversely rotated regardless of the action of the pulling force by using the reverse rotation preventing means.

Various methods can be used as this reverse rotation preventing means.

For example, the supporting frame 250 may be formed with an inclined protrusion such that the rotation axis 251 of the supporting frame 250 protrudes in a specific direction, and a groove may be formed at a corresponding position of the gear 231a in contact therewith. Alternatively, a slope may be formed on the surface of the rotating shaft 251 so as to face a specific direction, and a groove having a shape corresponding to the inner circumferential surface of the feed roller 210 may be formed.

Figs. 11 and 12 show an example of the above-described reverse rotation preventing means applied to the present embodiment 200. Fig.

Referring to FIG. 11, the reverse rotation preventing means includes a latching piece 290 and a latching wheel 239.

The engaging wheel 239 is a gear having a toothed surface formed on one side and a vertical surface formed on the other side, and is protruded from the gear 231a as shown in the figure.
