Description

Hemostatic device {HEMOSTATIC APPARATUS}

The present invention relates to a hemostatic device, and more particularly, to a hemostatic device which is wound around the patient's body to hemostasis.

The hemostatic device is used for hemostasis when there is bleeding due to a wound or a medical procedure, and is used to directly block the bleeding area or press the artery.

If there is bleeding on the arm or leg, etc., the hemostatic device used is made of a band or the like and the hemostatic device is wound around the arm or leg. However, in such a hemostatic device, it is difficult to compress the bleeding site or the artery sufficiently because the elasticity of the band exerts pressure on the patient's body. In addition, tightly tightening the band for sufficient pressure may cause discomfort to the patient and may also cause necrosis by blocking the flow of blood.

In order to prevent this, a hemostatic device of various structures has been proposed, but such a hemostatic device has a problem in that the structure is complicated and the manufacturing cost is high and the productivity is low.

The present invention relates to a hemostatic device which can press the bleeding site effectively and safely and the manufacturing cost is reduced.

In the hemostatic device according to the present embodiment, the band portion may include the first and second portions composed of different materials to improve the hemostatic effect, to prevent damage to the patient's body, and to simplify manufacturing to improve the productivity. Can improve.

That is, the first portion is composed of a first material having elasticity to apply an elastic force to the pressing portion to improve the hemostatic effect. The second portion is formed so that it can be easily combined with the coupling portion while preventing damage to the patient's body in the portion not directly related to hemostasis. This simplifies the structure while protecting the patient's body.

In addition, the third portion may simplify the connection structure with the pressing portion, the guide portion, and the buffer portion. The patient's body can be protected by a buffer positioned between the band portion and the patient's body.

1 to 3, the hemostatic device 100 according to the present embodiment includes a pressing part 10 for pressing the patient's body, and a band part 20 extending long to fix the pressing part 10 to the patient's body. ) And a guide part 30 fixed to the first end 201 of the band part 20 so as to pass through the second end 202 of the band part 20. Along with the band portion 20 and the patient body may include a buffer 40 formed to be located. This will be described in more detail as follows.

The pressing unit 10 is a portion that contacts the patient's body and compresses the bleeding site or the artery when the arm or leg with the bleeding site is wrapped in the patient's body. The pressing unit 10 may be formed to be round to the part touching the patient's body. This makes it possible to transfer pressure to the patient's body well without damaging the patient's body. For example, the pressing unit 10 may have a cylindrical shape in which the longitudinal direction is parallel to the width direction of the band unit 20. Then, the patient's body can be pressurized at a constant pressure without damaging the patient's body even if the body touches the patient's body at any angle. However, the present invention is not limited thereto, and of course, the pressing unit 10 may have various shapes.

The pressing unit 10 may be formed adjacent to the guide unit 30, which will be described in more detail later.

The pressing unit 10 may be made of a material harmless to the patient's body. In one example, the pressing member 14 may include a foamed resin (eg, a foamed styrene resin (also called styrofoam)). However, the present invention is not limited thereto, and the pressing unit 10 may include various materials.

Band portion 20 is a portion extending long to fix the hemostatic device 100 to the patient body. In this embodiment, the band portion 20 includes portions including different materials so that the pressing portion 10 presses the patient's body more efficiently, but does not damage the patient's body.

The first end 201 of the band part 20 is positioned with a guide part 30 fixedly immovable. An opening is formed in the guide part 30 to allow the band part 20 to pass therethrough. A coupling portion 22 is formed at the second end 202 of the band portion 20, and the coupling portion 22 is coupled to the surface of the band portion 20 (more precisely, the surface of the second portion 220). To be fixed.

In the present embodiment, the coupling portion 22 and the band portion 20 may be coupled in a Velcro tape type. That is, the engaging portion 22 is formed so that the locking portion 222 is formed and the band portion 20 is formed of a material to take the locking portion 222 of the coupling portion 22. The material of the band portion 20 will be described in more detail later. In this way, when combined in a Velcro tape type, it is not necessary to form a separate coupling portion on the surface of the band portion 20. Accordingly, the manufacturing process of the hemostatic device 100 can be simplified and the manufacturing cost can be reduced. However, the present invention is not limited thereto, and the coupling structure may be modified in various ways, such as a tip type or a sticker type.

In the band part 20 of the present exemplary embodiment, the band part 20 includes a first part 210 formed of a first material having elasticity, and a second part having a second material having a lower elasticity or less elasticity than the first material ( 220). In this case, the first portion 210 may be located closer to the guide portion 30 than the second portion 220. In addition, the first part 210 and the guide part 30 of the band part 20 may include a third part 230 having a material having a lower elasticity or no elasticity than the first material.

The first part 210, the second part 220, and the third part 230 may be formed of a fabric material so that the patient's body may be worn without burden. The first part 210 and the second part 220, the second part 220, and the third part 230 may be connected to each other by sewing. In the drawings, these seams are not shown for the sake of clarity and simplicity. However, the present invention is not limited thereto, and the first part 210, the second part 220, and the third part 230 may be connected by other methods.

More specifically, the first portion 210 may have a stretchable first material that may be stretched in the longitudinal direction of the band portion 20. That is, the stretch rate in the longitudinal direction of the band portion 20 in the first portion 210 may be greater than the stretch rate in the width direction of the band portion 20. The first portion 210 is located closer to the guide portion 30 where the pressing portion 10 is located than the second portion 220. Applying a force to extend the band portion 20 in the longitudinal direction extends the first portion 210 having elasticity to generate an elastic force in the first portion 210 adjacent to the pressing portion 10. This elastic force can be transmitted to the patient's body through the pressing unit 10 to press the patient's body more effectively. For example, the first portion 210 may include a rubber band formed to stretch only in the length direction of the band portion 20.

The second portion 220 is a portion extending from the first portion 210 to be stably fixed to the patient's body. The second portion 220 may be made of a second material to which the coupling portion 22 in the form of Velcro tape having the locking portion 222 may be coupled with low or no elasticity. The second part 220 may prevent the patient's body from being damaged unnecessarily and hardly pressed by the patient's body that is not directly related to hemostasis due to low or no elasticity. In addition, a second portion 220 is formed of a material to which the coupling portion 22 formed on the second end 202 of the band portion 20 may be coupled in a velcro tape type, and thus separate from the second portion 220. It is not necessary to form the coupling portion. Accordingly, the structure of the hemostatic device 100 can be simplified to simplify the manufacturing process and reduce the manufacturing cost. Various materials may be used as the second material, and for example, may include a nonwoven fabric.

The second portion 220 may be provided with a plurality of perforations 224 to reduce the discomfort of the patient by allowing the ventilation to occur smoothly. Although the drawings illustrate that the plurality of perforations 224 are circular, the present invention is not limited thereto. Accordingly, the plurality of perforations 224 may have various polygonal shapes such as triangles, squares, hexagons, and the like.

In this case, the ratio of the total area of the plurality of perforations 224 to the total area of the second portion 220 may be 0.01 to 0.1. If the ratio is less than 0.01, ventilation may not occur smoothly, and if the ratio exceeds 0.1, the strength of the second portion 220 may be lowered.

The third portion 230 is a portion connecting the first portion 210 and the guide portion 30 of the band portion 20 and may have a material having a lower elasticity or no elasticity than the first material. As a result, the band part 20 can be stably fixed to the guide part 30. The third portion 230 may have the same second material as the first portion 210, and in this case, the manufacturing process may be simplified and the manufacturing cost may be reduced.

In this embodiment, the pressing portion 10, the band portion 20, the guide portion 30, and the buffer portion 40 can be firmly fixed using the third portion 230 as a simple structure. It will be described in more detail with reference to.

The third portion 230 includes a first end 232 adjacent to the first portion 210 and a second end 234 constituting the first end 201 of the band portion 20. First, the second end portion 234 of the third portion 230 is passed through the guide portion 30 so as to be caught by one side of the guide portion 30 and the first end portion 232 side portion and the second end portion ( 234) side portions overlap each other. The first end portion 232 side portion and the second end portion 234 side portion thus overlapped are fixed to each other by the first fixing portion 231. In this state, the portion of the second end portion 234 of the third portion 230 is wound around the outer surface of the pressing portion 10, and then the portion adjacent to the guide portion 30 in the third portion 230 is wound. The parts adjacent to the first end 201 side meet and are fixed to each other by the second fixing part 232. In this state, the third portion 230, the first end portion 232 side portion, and the loose portion 30 positioned between the second fixing portion 232 and the second end portion 234 of the third portion 230 are removed. The overlap is fixed to each other by the third fixing part 233. Then, the pressing unit 10, the band unit 20, the guide unit 30, and the buffer unit 40 can be fixed to each other by a simple structure and method, thereby improving the hemostatic effect of the hemostatic device 100 and improving the production productivity. Can improve.

The second portion 220 is formed longer than the first portion 210 and the third portion 230, the coupling portion 22 formed in the second end 202 of the band portion 20 even if the size of the patient's body changes To be coupled to the second portion 220.

At this time, the length of the first portion 210 relative to the length L2 of the second portion 220 (the first portion between the third portion 230 and the second portion 230, which can be actually stretched more accurately). A length L1 / L2 of 210 may be 0.05 to 0.25. If the ratio is less than 0.05, it may be difficult to effectively transmit the elastic force to the patient's body. If the ratio is greater than 0.25, the elastic first part 210 may be located on a part of the patient's body that is not related to hemostasis and may damage the part. When the patient's body wearing the hemostat device 100 is small, After coupling, the coupling portion 22 may be positioned near the first portion 210, and thus coupling may not be performed.

And the length of the third portion 230 positioned between the first portion 210 and the guide portion 30 with respect to the length L1 of the first portion 210 (more precisely, from the first end 232). The ratio L3 / L1 of the distance between the first fixing parts 231 and L3 may be 0.1 to 1.5. If the ratio is less than 0.1, the connection with the guide unit 30 may not be smooth. When the ratio exceeds 1.5, the first portion 210 may be located far from the pressing portion 10 such that the elastic force formed by the elasticity of the first portion 210 may not be effectively transmitted to the pressing portion 10.

Then, the total length in the state where no force is applied to the band portion 20 is referred to as L, and the band portion 20 when the band portion 20 is pulled in the longitudinal direction (based on the force applied immediately before the elastic limit value). When the increased length is? L, the ratio of? L to L (? L / L) may be 0.05 to 0.5 (for example, 0.05 to 0.25). If the ratio is less than 0.05, the elasticity ratio is small, the elastic force formed by the elasticity of the first portion 210 may not be effectively transmitted to the pressing portion 10. If the ratio exceeds 0.5, the elastic first part 210 may be located on a part of the patient's body that is not related to hemostasis, and the part may be damaged, and when the patient's body wearing the hemostat device 100 is small After coupling, the coupling portion 22 may be positioned near the first portion 210, and thus coupling may not be performed. In addition, the ratio may be 0.05 ~ 0.5 to more effectively prevent the patient body damage.

The buffer unit 40 is positioned between the band unit 20 and the patient body. The buffer 40 serves to protect the patient's body by wrapping each part of the patient's body (for example, wrist, ankle, arm circumference, leg circumference, head, waist, neck, hip, etc.). In addition, the buffer 40 may smooth the flow of blood in a portion not related to hemostasis to mitigate necrosis.

The buffer part 40 may include a porous material (eg, a sponge) to effectively prevent damage to the patient's body. The porosity of the buffer portion 40 may be, for example, 1 to 30%. Such porosity is limited to a range that can have structural stability while giving warmth to the patient's body. However, the present invention is not limited thereto, and the buffer part 40 may have various porosities.

At this time, the thickness of the shock absorbing portion 40 is greater than the thickness of the band portion 20 can effectively prevent damage to the patient's body. For example, the thickness of the shock absorbing portion 40 may be 5 to 20 times the thickness of the band portion 20.

In the present embodiment, the buffer part 40 extends along the length direction of the band part 20, but is formed to be shorter than the band part 40 so as not to interfere with the pressing action of the pressing part 10, and the entire first part 210. The first portion 210 may not be in direct contact with the patient's body so as to overlap the. For example, the length ratio of the buffer unit 40 to the length of the band unit 20 may be 0.2 ~ 0.5. If the ratio is less than 0.2, the buffer part 40 may not completely cover the first part 210, and a part of the first part 210 may contact the patient's body to damage the patient's body. When the ratio exceeds 0.5, the hemostatic device 100 is wound around the body of the patient to be worn at least once, so that the buffer unit 40 is positioned between the pressing unit 10 and the patient body, whereby the pressing unit 10 It can interfere with the pressing action.

The method of mounting the above-described hemostatic device 100 on the patient's body will be described in more detail with reference to FIGS. 4A and 4B. 4A and 4B are perspective views illustrating a method of mounting the hemostatic device of FIG. 1.

First, as shown in FIG. 4A, a state in which the buffer part 40 is interposed between the pressing part 10 of the hemostatic device 100 is placed on a patient's body (for example, an arm or a leg) that requires hemostasis. The band 20 is wound around the patient's body. As shown in FIG. 4B, the second end 202 of the band portion 20 in which the coupling portion 22 is formed is inserted into the guide portion 30 and then pulled in the opposite direction to sufficiently extend the first portion 210. Pressing unit 10 to sufficiently press the patient body. In this state, the locking portion 222 of the engaging portion 22 of the second end 202 is fixed to the second portion 220. Then, the elastic force generated by extending the first portion 210 is applied to the pressing unit 10 to be mounted on the patient's body in a state of sufficiently pressing the patient's body that requires hemostasis so that hemostasis is continuously performed.

In the hemostatic device 100 according to the present embodiment, the band part 20 includes first and second parts 210 and 220 made of different materials. At this time, the first portion 210 is made of a first material having an elasticity to improve the hemostatic effect by the pressing unit 10. In addition, the second part 220 may be composed of a second material that may be combined with the coupling part 22 without discomfort to the patient in a part not directly related to hemostasis, thereby simplifying the structure. The third portion 230 is formed to simplify the structure of the pressing portion 10, the guide portion 30, and the buffer portion 30. In addition, the patient's body can be protected by the buffer unit 40 located between the band unit 10 and the patient's body.

As described above, the hemostatic device 100 according to the present embodiment can improve the hemostatic effect, prevent damage to the patient's body, and improve manufacturing productivity by simplifying the structure.
