Description

COMPRESSION STYPTIC BAND

Technical Field

[1] The present invention relates to a compression styptic band that can be attached to a minutely incised operation region after conducting a percutaneous angiography and a percutaneous angioplasty through a femoral part, a wrist, an armpit or the like and that can stop bleeding by compressing the incised operation region with a compression means. Background Art

[2] In general, blood stanching needs to be exercised to a minutely incised operation region after conducting a percutaneous angiography and a percutaneous angioplasty through a femoral part, a wrist, an armpit or the like. Conventionally, blood stanching to the operation region has been performed using a simple band or a swab. This method suffers from a reduced stanching effect and involves many difficulties in performing the stanching.

[3] In an effort to solve this problem and for the purpose of effectively compressing and stanching the minutely incised operation region, there have been proposed various kinds of stanching devices, including a compression styptic band using a balloon, a physical compression disc, an intravascular stanching device using an expensive collagen, an intravascular operation device using an operation suture, and a clip.

[4] Although the compression styptic band using a balloon is structurally simple and easy to use, it has no ability to apply a compression force great enough to perform intended stanching. The physical compression disc has a drawback in that a sand bag needs to be placed on the operation region for an extended period of time after stanching has been accomplished. The intravascular stanching device using an expensive collagen, the intravascular operation device using an operation suture and the clip have a shortcoming in that they are costly and complex to use, thus suffering from an increased failure-to-use rate.

[5] More specifically, as shown in Figs. 1 and 2, the conventional compression styptic band using a balloon consists of a balloon 3 having an air injection valve 2 and a band portion 5 surrounding the balloon 3.

[6] With this compression styptic band, the band portion 5 is bonded in place in a state that the lower end of the balloon 3 is exactly aligned with a minutely incised operation region. Then, the air is injected into the balloon 3, whereby the balloon 3 is inflated to compress and stanch the operation region.

[7] However, due to the fact that the operation region is compressed by inflating the balloon with an air pressure, the balloon-used compression styptic band poses a problem in that it is difficult to acquire a great enough compression force, which in turn leads to noticeable reduction in the blood stanching effect.

[8] Furthermore, since the balloon is designed to have a hemispherical compression portion when inflated, it is not easy to use the compression styptic band in such a way that the hemispherical compression portion is accurately placed on the operation region. This poses another problem in that the hemispherical compression portion fails to effectively compress the operation region. Disclosure of Invention Technical Problem

[9] In view of the above-noted and other problems inherent in the prior art, it is an object of the present invention to provide a compression styptic band that can provide a great enough compression force and can maximize a blood stanching effect by employing a hard compression member, in place of the conventionally used balloon, to compress a minutely incised operation region after conducting a percutaneous angiography and a percutaneous angioplasty through a femoral part, a wrist, an armpit or the like.

[10] Another object of the present invention is to provide a compression styptic band that can be easily used and can maximize a blood stanching effect by employing a compression member having a broad compression surface which can be accurately positioned on a minutely incised operation region to compress the same.

[11] A further object of the present invention is to provide a compression styptic band that can increase a compression effect and can maximize a blood stanching effect by employing a band portion which can be attached to an operation region or wrapped around a wrist, an ankle or other bodily parts. Technical Solution

[12] With these objects in view, the present invention provides a compression styptic band comprising:

[13] a compression means for compressing a minutely incised operation region of a bodily part after conducting a percutaneous angiography and a percutaneous angioplasty through a femoral part, a wrist, an armpit or other bodily parts; and

[14] a band portion formed around the compression means and removably attachable to the bodily part,

[15] wherein the compression means includes a main body having a central thread hole, a knob having a male thread portion threadedly engaged with the central thread hole of the main body, and a compression member having a compression surface, the compression member coupled to a tip end of the knob and adapted to move toward and away from the bodily part to compress the incised operation region. [16] With the compression styptic band as recited above, an annular insertion protrusion is formed at the tip end of the knob and an annular reception groove for rotatably receiving the insertion protrusion is formed on an inner side of the compression member, and wherein the insertion protrusion has a stopper bulge and the reception groove has a stopper recess that engages with the stopper bulge of the insertion protrusion to keep the compression member against removal.

[17] With the compression styptic band as recited above, the compression surface of the compression member is formed of a generally planar portion having an increased area.

[18] With the compression styptic band as recited above, the compression member has a circumferential recess.

[19] With the compression styptic band as recited above, the band portion has opposite end extensions each formed of a Velcro fastener and adapted to be wrapped around the bodily part. Advantageous Effects

[20] The compression styptic band of the present invention is designed to advance a compression member toward a minutely incised operation region by the threading action of a knob and therefore can provide a greater compressing force than is available in the conventional balloon-type styptic band. Furthermore, the present compression styptic band is extremely easy to use because it eliminates the need to inject an air into a balloon. Moreover, thanks to the fact that the compression member of the present compression styptic band has a wide and planar compression surface and further that the band portion thereof can be wrapped around a wrist, an ankle or other bodily parts, it is possible to attach the compression styptic band to an operation region more easily and accurately than in the conventional styptic band. This helps to increase a blood stanching effect and to maximize reliability in use. Brief Description of the Drawings

[30] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[31] Referring to Figs. 1 to 5, a compression styptic band of the present invention includes a compression mechanism 10 for compressing a minutely incised operation region after conducting a percutaneous angiography and a percutaneous angioplasty through a femoral part, a wrist, an armpit or the like, and a band portion 30 formed around the compression mechanism 10.

[32] The compression mechanism 10 includes a main body 15 having a central thread hole 16, a knob 20 having a male thread portion 22 threadedly engaged with the central thread hole 16 of the main body 15, and a compression member 25 having a compression surface 26, the compression member 25 being coupled to a tip end of the knob 20. By rotating the knob 20, the compression member 25 is moved back and forth to perform a compression operation.

[33] An annular insertion protrusion 23 is formed at the tip end of the knob 20 and an annular reception groove 27 for rotatably receiving the insertion protrusion 23 is formed on an inner side of the compression member 25. The insertion protrusion 23 has a stopper bulge 23a on its outer circumference and the reception groove 27 has a stopper recess 27a that engages with the stopper bulge 23a to keep the compression member 25 against removal.

[34] Preferably, the compression surface 26 of the compression member 25 is formed of a generally planar portion having an increased area. The compression surface 26 may be formed into a rectangular shape in view of the fact that the minutely incised operation region extends long.

[35] It is preferred that the band portion 30 be made of a non-elastic material in order to increase the compressing force of the compression mechanism 10. The band portion 30 has an adhesive layer and extends long from the main body 15 of the compression mechanism 10 in the opposite directions. Reference numeral 32 designates a release sheet removably bonded to the adhesive layer of the band portion 30.

[36] Next, description will be given on the operation of the novel compression styptic band configured as above.

[37] The release sheet 32 is first removed from the band portion 30 and then the band portion 30 is bonded to a bodily part in such a manner that the compression surface 26 of the compression member 25 is placed on a minutely incised operation region at the end of a percutaneous angiography and a percutaneous angioplasty conducted through a femoral part, a wrist, an armpit or the like. In this process, the task of placing the compression member 25 on the operation region can be performed with ease, thanks to the fact that the compression surface 26 of the compression member 25 is wide and planar.

[38] If the knob 20 is rotated in such a state, the male thread portion 22 of the knob 20 threadedly engaged with the central thread hole 16 of the main body 15 moves forward, thereby advancing the compression member 25 coupled to the tip end of the knob 20 as illustrated in Fig. 6.

[39] Owing to the fact that the insertion protrusion 23 of the knob 20 remains rotatably inserted into the reception groove 27 of the compression member 25, the compression member 25 makes only the advancing movement without any rotation as the knob 20 manually rotated. Along with this advancing movement, the compression surface 26 of the compression member 25 compresses and stanches the minutely incised operation region.

[40] Thanks to the fact that the compression member 25 is given a compressing force by the threading action between the knob 20 and the main body 15, it is possible for the compression member 25 to apply a greater compressing force than is available in the conventional balloon-type styptic band. Furthermore, the wide compression surface 26 of the compression member 25 is capable of effectively compressing the operation region and thus providing a superior blood stanching effect.

[41] If a user wishes to reduce the compressing force applied on the operation region by the compression member 25, the compression member 25 is caused to move backward by reversely rotating the knob 20. This means that the compression styptic band of the present invention allows the user to control the compressing force acting against the operation region.

[42] Shown in Figs. 7A and 7B are other examples of the compression member employed in the compression styptic band of the present invention. The compression members 25 shown in these figures have a "V"-shaped recess 28 formed on one side thereof, although they differ in overall contour from each other.

[43] The reason for forming the recess 28 is to ensure that a tube or sheath 50 inserted into a blood vessel can be drawn to the outside through the recess 28 as illustrated in Fig. 8. With this arrangement, the compressing and stanching operation is performed by positioning a bodily cutout for passage of the tube or sheath 50 in alignment with the recess 28. That is to say, the compressing and stanching operation is carried out in a state that the bodily cutout is surrounded by the recess 28 of each of the compression members 25. By drawing the tube or sheath 50 out of a blood vessel in this state, it is possible to perform the tube drawing task with minimized bleeding and pain.

[44] Fig. 9 shows a compression styptic band in accordance with another embodiment of the present invention. The compression styptic band of the present embodiment differs from that of the preceding embodiment in that the band portion 30 has opposite end extensions 35 each formed of a Velcro fastener 36 and adapted to be wrapped around a wrist, an ankle or other bodily parts. Use of the Velcro fastener 36 is to avoid any reduction in compressing force against the operation region that would be caused by a relatively weak bonding force of the adhesive layer in the band portion 30 of the preceding embodiment. By wrapping the opposite end extensions 35 of the band portion 30 around a wrist, an ankle or other bodily parts and attaching them to each other by use of the Velcro fastener 36, it becomes possible for the compression member 25 to firmly compress the operation region and to increase the blood stanching effect. Industrial Applicability

[45] As described above, the compression styptic band of the present invention is designed to advance a compression member toward a minutely incised operation region by the threading action of a knob and therefore can provide a greater compressing force than is available in the conventional balloon-type styptic band. Furthermore, the present compression styptic band is extremely easy to use because it eliminates the need to inject an air into a balloon. Moreover, thanks to the fact that the compression member of the present compression styptic band has a wide and planar compression surface and further that the band portion thereof can be wrapped around a wrist, an ankle or other bodily parts, it is possible to attach the compression styptic band to an operation region more easily and accurately than in the conventional styptic band. This helps to increase a blood stanching effect and to maximize reliability in use.
