Description

The technical field to which the utility model relates.

This utility model relates to a hemostatic device that is attached to the patient’s limb in that part of the limb where bleeding must be stopped, and which, by inflating the balloon, applies pressure to the area so as to stop the bleeding.

State of the art

When a procedure is carried out for medical treatment, research or diagnosis, including the transdermal introduction of an instrument such as a catheter into the blood vessel, it is necessary to stop bleeding in the puncture site after subsequent removal and removal of the catheter. The prior art already knows devices that are attached by wrapping around the part of the arm or leg where the puncture site is located, and compressing the puncture site in which bleeding must be stopped (for example, in US Pat. No. 7,494,477).

In such a hemostatic device, the tape wrapped around the puncture site of the arm or leg is secured by fixation means, thereby maintaining the pressure of the balloon pressing the puncture site. However, in order to prevent the likelihood of excessive load on neighboring nerves or the ulnar artery, it is recommended to loosely wrap the tape, loosening it by about 15 mm at the stage of wrapping before inflating the balloon.

“Loosen by approximately 15 mm” means that, compared with the condition that the tape wrapped around the arm or leg is in contact with the arm or leg around their circumference, the tape is wrapped so that its circumferential length is increased by approximately 15 mm

However, since there is no standard for a weakened state, if the tape is tightly wrapped, pain or stiffness occurs in the area around which the tape is wrapped. If the tape is too loose, the pressure created by the balloon is insufficient to stop the bleeding.

Utility Model Disclosure

One objective of this utility model is to provide a hemostatic device in which by providing an element that supports the interval and wrapping the tape around the limb, applying force to the puncture site to stop bleeding by inflating the balloon, you can set the appropriate compression ratio in a simple reproducible way.

Utility Model Implementation

Further, based on embodiments for a hemostatic device including an interval supporting member, embodiments are described in detail with reference to the drawings. The options below are exemplary products or ways to implement the technical idea of this utility model. The technical idea of this utility model is not limited to a hemostatic device, and can be applied to medical instruments in general. The types of materials and conditions for configurations, etc., are not limited to those described below. Various modifications of the technical idea of the present utility model can be added that are within the scope of the technique defined in the claims of the utility model.

Figure 1 is a depiction of an embodiment of a hemostatic device comprising an interval supporting member, bottom view; showing the side of the device that serves as the inner surface when the device is attached to the wrist of the patient. FIG. 2 is a sectional view of a hemostatic device including an interval supporting member, as shown in FIG. 1, during use to stop bleeding.

The hemostatic device 1 shown in FIG. 1 is used to stop bleeding at the puncture site 510 (where bleeding must be stopped) after removing a tool such as a catheter that was inserted percutaneously into the artery through an opening formed in the limb, which is like a wrist 500 (limb ), for a medical purpose, such as treatment, research, or diagnosis. This hemostatic device 1 has a tape 2 adapted to wrap around the wrist 500 and having a width of about 40 mm; an external fastener 3 made of breathable material as a means of attaching the tape in a wrapped state to the wrist 500; curved plate 4, cylinder 5, secondary cylinder 6, mark 7 and an element supporting interval 9.

Tape 2 is a flexible belt-shaped element. As shown in figure 2, the tape 2 is attached to the wrist 500, being wrapped one full revolution around the wrist 500 and out, and has parts of the tape 2 near the ends overlapping each other. The overlapping portions of the tape 2 are then fastened (or connected) by means of an external fastener 3 (which is described later), such as a hook and loop fastener (for example, a product commonly known in Japan as Magic Tape®).

The material of which tape 2 is made is not subject to any particular limitation, and is selected so that through it it is possible to see a piercing portion 510. Illustrative examples include polyvinyl chloride; polyolefins such as polyethylene, polypropylene, polybutadiene and ethylene vinyl acetate (EVA) copolymers; polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT); polyvinylidene chloride, silicones, polyurethanes; various thermoplastic elastomers, such as polyamide elastomers, polyurethane elastomers and polyester elastomers, and any combination of the above, for example, in the form of mixtures of resins, polymer alloys or laminates.

In this regard, it is preferable that the tape 2 in the present embodiment be substantially transparent (transparent to visible light), so that the piercing portion 510 can be easily seen from the outside, and the mark 7 (described in detail below) can simply be positioned appropriately in the piercing portion 510.

The tape 2 may comprise, near its center, a holder of a curved plate 21 for holding the curved plate 4 described later. In the embodiment shown in FIG. 1, the holder of the curved plate 21 is constructed in part from a separate tape-shaped element connected to the outer (or inner) surface of the tape 2 a suitable method, such as welding (e.g., heat welding, high frequency welding, ultrasonic welding) or adhesion (such as using an adhesive or solvent), so as to form a two-layer structure uw. The curved plate 4 is inserted into the gap in a double layer and is thus held.

The means that can be used to secure the tape 2 in a wrap state of the wrist 500 are not limited to external fasteners 3. Other suitable means include latches, buttons, and elements such as buckles through which the ends of the tape 2 pass.

The curved plate 4 is inserted into the gap in the two-layer structure of the holder of the curved plate 21 on the tape 2, and thus is held on the tape 2.

The curved plate 4 is formed so that at least a portion of it is curved towards the inner side of the tape 2. This curved plate 4 is constructed from a material that is more rigid than the tape 2 and maintains a substantially fixed shape.

The curved plate 4 is provided with an air hole (not shown) in a position that does not overlap the balloon 5 (described below), so that the air hole in the curved plate 4 communicates with the air hole (not shown) in the belt 2.

In this embodiment, the curved plate 4 has a shape elongated in the longitudinal direction of the tape 2. As shown in FIG. 2, the curved plate 4 has a central portion 41 in its longitudinal direction that is not substantially curved, and thus forms a flat plate. The curved plate 4 also has, on either side of its central part 41, curved parts 42, curved towards the inner side of the tape 2 and in the longitudinal direction of the tape 2 (in the direction of the circumference of the wrist 500). The curved portions 42 have a radius of curvature R2 that is smaller than the radius of curvature R1 of the center portion 41 (in the illustrated embodiment, R1 is substantially 180 °).

The material of which the curved plate 4 is made does not have any particular limitation, and is selected so that a piercing portion can be seen through it. Examples of materials from which a curved can be made: plate 4 include acrylic resins, polyvinyl chloride (in particular rigid polyvinyl chloride), polyolefins such as polyethylene, polypropylene and polybutadiene, polystyrene, poly (4-methyl-1-pentene), polycarbonates , ABS plastics, polymethyl methacrylate (PMMA), polyacetals, polyarylates, polyacrylonitriles, polyvinylidene fluorides, ionomers, copolymers of acrylonitrile butadiene styrene, polyesters such as polyethylene terephthalate (PET) and polybutylene copolymers styrene butadiene, Panchromatic and aliphatic polyamides, and fluorocarbon resins such as polytetrafluoroethylene.

In this regard, the curved plate 4 in this embodiment is preferably substantially transparent (transparent to visible light) so that the piercing portion 510 can be easily seen from the outside and the mark 7 (described in detail below) can simply be positioned appropriately in the portion piercing 510.

In this regard, the curved plate 4 may have a non-curved part, such as the Central part 41, and thus, can be curved along its entire length.

The tape 2 is connected to the inside of the cylinder 5, made of flexible material. The balloon 5 is filled with liquid (gas, such as air, or liquid) introduced into it, and thus exerts pressure on the piercing portion 510 on the wrist 500.

The balloon 5 is located near one end of the curved plate 4 in its longitudinal direction. That is, in the arrangement shown in FIG. 1, the balloon 5 is in a position substantially overlapping the right half of the curved plate 4.

The material of which balloon 5 is made is not subject to any restriction of the material allowing the piercing section 510 to be seen. For example, a material similar to the material for making tape 2 can be used. In order to facilitate the attachment of balloon 5 to tape 2 by welding, and thus facilitate production of a hemostatic device 1, it is preferable that the balloon 5 be made of material of the same nature or type as the material for the manufacture of tape 2.

In this regard, it is preferable that the balloon 5 in this embodiment is substantially transparent (transparent to visible light), so that the piercing portion 510 can be easily seen from the outside, and the mark 7 (described in detail below) can simply be positioned appropriately in the portion piercing 510.

The balloon 5 may have a structure in which the edges of sheets made of the above material are glued together by a suitable process, such as welding or adhesion, to form a bag variety. In the device shown in FIG. 1, the balloon 5 is substantially square in an unfilled state.

The balloon 5 is connected to the tape 2 by means of a flexible connector 11. In the embodiment shown, the balloon 5 is connected to the tape 2 by the connector 11 only on the side of one end of the curved plate 4; that is, only on the right side in FIG. The connector 11 has a relatively short length, thus keeping the balloon 5 tied in a position deflected to one end of the curved plate 4. The connector 11 is preferably made of the same material as the balloon 5.

As shown in FIG. 1, the hemostatic device 1 of this embodiment has a mark 7 provided on the inner surface of the balloon 5, that is, the surface in contact with the piercing section 510. Providing such a mark 7 on the balloon 5 facilitates the proper location of the balloon 5 in the piercing section 510 , which in turn prevents the loss of blood and the formation of a hematoma due to improper location of the balloon 5.

As shown in FIG. 1, it is preferable that the mark 7 is provided in the center of the balloon 5. Since this allows the center of the balloon 5 to be properly positioned in the piercing section 510 when the balloon 5 is inflated, the compressive force exerted by the balloon 5 reliably acts on the piercing section 510.

Mark 7 is not limited to any particular form. Examples of suitable shapes include round, triangular, and square. 1, mark 7 has an annular shape.

In this regard, it is possible to place a mark 7 on the outer surface of the cylinder 5, that is, on the side opposite to the surface of the cylinder 5, which is in direct contact with the piercing section 510 (the back side on the plane of FIG. 1).

Alternatively, instead of being placed on balloon 5, mark 7 can be placed on tape 2, on curved plate 4, or on secondary balloon 6 (which is described later). In such cases, it is preferable to place the mark 7 so that it can be placed on top of the center of the cylinder 5.

As shown in figure 1, the cylinder 5 is also connected to the pump 8 for introducing liquid into the cylinder 5. The pump 8 consists of a flexible tube 81 connected at the proximal end to the cylinder 5, having a cavity communicating with the inside of the cylinder 5, a bulb 82 provided at the distal end of the tube 81, and a tubular connector 83 connected to the bulb 82.

The balloon 5 is inflated by inserting a protruding syringe tip (not shown) into the connector 83 and pushing the syringe piston so that liquid is introduced from the syringe through the pump 8 into the cylinder 5. As soon as the liquid is introduced into the cylinder 5 and the protruding syringe tip is removed from the connector 83, the check valve inside the connector 83 is closed, preventing leakage of fluid from it, and keeping the balloon 5 inflated.

As shown in FIG. 2, a secondary balloon 6 constructed of a flexible material can be provided between the curved plate 4 and the above balloon 5 so that the entire balloon 6 or part thereof overlaps the balloon 5. This secondary balloon 6 acts as a pressure member for pressing the cylinder 5.

Under the pressure of the filling fluid, the secondary cylinder 6 exerts a compressive force on the cylinder 5 (shown by arrow f in FIG. 2), which is directed essentially to the center 520 of the wrist 500. Under the influence of this compressive force f from the secondary cylinder 6, the cylinder 5 in turn exerts a compressive force force to the puncture site 510 (arrow F in FIG. 2), which acts more in a beveled or inclined direction (to the center 520 of the wrist 500) than in the direction vertically downward (i.e., in the vertical direction with respect to the surface of the wrist 500) . This arrangement provides a better hemostatic effect, and thus is able to more reliably stop the bleeding than the compression applied to the piercing section 510 in a vertical downward direction.

The material of which the secondary balloon 6 is made is not subject to any particular limitation, and is selected so that through it it is possible to see the piercing section 510. For example, materials similar to the above materials for manufacturing the tape 2 can be used. It is preferred that the balloon 6 was essentially transparent (transparent to visible light), so that the piercing portion 510 could be easily seen from the outside, and mark 7 could simply be positioned appropriately in the piercing portion 510.

In this embodiment of the utility model, the secondary balloon 6 has a smaller width in the longitudinal direction of the belt 2 than the balloon 5. Therefore, the balloon 6 is smaller than the balloon 5, and thus exerts pressure locally on the balloon 5. This more reliably allows direction the compressive force F applied by the cylinder 5 to the piercing portion 510, inclined.

In this embodiment, as mentioned above, the curved plate 4 has on the side where the cylinder 5 is located (the right side in FIG. 2), a curved part 42 with a smaller radius of curvature than the central part 41 of the curved plate 4. The secondary cylinder 6 is in contact , through the tape 2, with the curved part 42 of the curved plate 4 or part of its right side in figure 2. In this way, the direction of the force generated by the secondary cylinder 6 from the curved plate 4, i.e. the normal direction of the curved plate 4, where it contacts the secondary cylinder 6 through the tape 2, is inclined to the center 520 of the wrist 500. As a result of the direction of the compressive force f and the compressive force F can be more reliably made inclined.

In this embodiment, a portion of the balloon 5 and a portion of the secondary balloon 6 are joined together in any suitable manner, such as welding or adhesion. As a result of the connection, a connecting part 12 (at the hole) is formed as a means of communication between the inner part of the cylinder 5 and the inner part of the secondary cylinder 6. When the liquid is introduced into the cylinder 5 in the manner described above, some of the liquid passes through the communication port 12 to the secondary cylinder 6 so that the secondary balloon 6 is inflated as the balloon 5 is inflated. Thus, both cylinders can be inflated in a single operation, providing excellent ease of use and efficiency.

In this embodiment, the secondary balloon 6 is connected to the tape 2 via a connector 13 on the same side as the connector 11 with the balloon 5 (i.e., the right side in FIG. 2). Accordingly, the secondary cylinder 6 more easily and reliably reaches the indicated orientation. This more simply ensures that the compressive force f is applied to the balloon 5 to act in an oblique direction (i.e., in a direction that causes the balloon 5 to substantially affect the center 520 of the wrist 500), thereby achieving a better hemostatic effect.

In this regard, in this utility model, the compression element pressing on the cylinder 5 is not limited to the secondary cylinder 6. For this purpose, other compression elements can be used, including tampons made of spongy substance, elastomeric material, a group of fibers such as cotton, or combinations thereof.

As shown in FIG. 1, the element supporting the interval 9 is connected to the tape 2 by means of a flexible connector 91. Alternatively, instead of connecting to the tape 2 by the connector 91, the element supporting the interval 9 can be fixed in position by a part of the element supporting the interval 9 on tape 2 by clamping, etc.

A method of using a hemostatic device 1, including an interval supporting member, is described below.

[1] Before installing a hemostatic device 1, including an interval-supporting element, on wrist 500, balloon 5 and secondary balloon 6 are placed in an empty state. In the case of the wrist 500, the puncture site 510 on the artery is usually placed in a position inclined towards the thumb on the inside of the wrist 500 (where the tendons are located). In general, a stylet catheter is left at the piercing site 510. The tape 2 is wrapped around the wrist 500 in a state where the stylet catheter is left, following around the wrist 500 with the help of the element supporting the interval 9, without the use of tensile force. The balloon 5 (tape 2) is positioned so that the mark 7 provided on the balloon 5 lies on top of the piercing section 510. The parts near both ends of the ribbon 2 are fixed (connected) by applying the hook side of the outer fastener 31 to the looped side of the outer fastener 32.

[2] As soon as the hemostatic device 1 including the interval supporting element is attached to the wrist 500, the interval supporting element 9 is separated, a syringe (not shown) is inserted into the connector 83 on the pump 8, and liquid is introduced into the cylinder 5 and the secondary cylinder 6 as described above, in a predetermined amount, in accordance with the clinical case, thereby inflating balloon 5 and secondary balloon 6.

In one embodiment, before the balloon 5 is inflated, the tapes 2 are wrapped around the wrist 500 by applying an element supporting the interval 9. In essence, when the element supporting the interval 9 is disconnected, the degree of attenuation of the tape 2 is kept constant at each rotation. Accordingly, the compressive force acting on the piercing portion 510 by inflating the balloon 5 when a predetermined amount of fluid is introduced is maintained almost constant at each revolution.

When the element supporting the interval 9 is disconnected, the attenuation of the tape 2 is preferably from 10 to 25 mm. If the attenuation is lower than 10 mm, the compressive force acting on the piercing portion 510 by inflating the balloon 5 becomes unnecessarily high. If the attenuation exceeds 25 mm, the compressive force acting on the piercing portion 510 by inflating the balloon 5 becomes insufficient, so that the piercing portion 510 extends beyond the balloon 5, or the tape 2 can be displaced from the wrist 500.

[3] When the balloon 5 and the secondary balloon 6 are inflated, the syringe is released from the connector 83. A stylet catheter is removed from the piercing section 510. The balloon 5 and the secondary balloon 6 are maintained inflated and the compression state is maintained by a predetermined compressive force acting on the piercing portion 510 (see FIG. 2). In this state, the balloon 5 exerts pressure locally on the piercing portion 510 (and its surroundings). Due to the inflation of the balloon 5 and the secondary balloon 6, the curved plate 4 moves away from the surface of the wrist 500, which makes it difficult to contact the curved plate 4 with the wrist 500. As a result, the compressive force intensively affects the piercing section 510 (and its surroundings). Before inflation of the balloon 5 after disconnecting the element supporting the interval 9, the tape 2 is wrapped around the wrist with a predetermined length of attenuation. As a result, a compressive force with a predetermined degree of pressure is set. Accordingly, the compressive force acting on the puncture site 510 by means of the balloon 5 does not cause excessive load on neighboring nerves or the ulnar artery.

[4] After removing the stylet catheter from the puncture site 510, if bleeding is stopped, the syringe is reconnected to the connector 83 so as to withdraw fluid from the balloon 5. Next, the hemostatic device including the interval supporting member is disconnected from the wrist 500 to complete the procedure stop bleeding.

The time for stopping bleeding from the beginning of the procedure for stopping bleeding to the end of the procedure for stopping bleeding can be only two or three hours instead of ten or more hours, in accordance with the size of the used catheter. However, if a tape 2 is used including an interval supporting member, overpressure or insufficient pressure on the piercing portion 510 can be prevented.

Examples

Example 1

FIG. 3 is a cross-sectional view showing an example 1 of a hemostatic device 1 including an interval supporting member.

In Example 1, by using a round rod 10 made of plastic with a diameter of ⌀ 10 mm as an element supporting the interval 9, a method for using a hemostatic device including an element supporting the interval from paragraphs [1] to [4] is carried out.

A round rod with a diameter of ⌀ 10 mm is attached, the tape 2 is wrapped around the wrist 500 without the application of tensile force. Further, when the round rod 10 is detached, the tape 2 has an attenuation length of about 15 mm.

An element supporting interval 9 is not limited to a cylindrical rod, and may have any shape that can be placed between the wrist 500 and the hemostatic device 1, such as a rectangular rod, including a cuboid and cubic shape, a round, and a triangular rod, including a truncated cone with a light bias.

Example 2

FIG. 4 is a cross-sectional view of Example 2 of a hemostatic device 1 including an interval supporting member.

In a state where the tape 2 is applied to an overlay length of 8 mm and clamped with a clamp 20, the tape 2 is wrapped around the wrist 500 without applying a pulling force. Then, when the clip 20 is disconnected, the tape has an attenuation length of 16 mm.

Even if the time to stop bleeding using a hemostatic device 1, including an element that supports the interval, exceeds ten hours, or if you use the element that supports the interval 10, from example 1, or the element that supports the interval 10, from example 2, there is no pain or numbness due to excessive pressure on the puncture site 510 or an increase in the time required to stop the bleeding, due to insufficient pressure.

In the presented example, a hemostatic device 1 is described having one element supporting the interval. However, a plurality of interval supporting elements can be provided. As a result, the degree of pressure can be adjusted step by step.

Example 3

5 is a sectional view showing a hemostatic device 1 of Example 3, including an interval supporting member.

In Example 3, by using, as an element supporting the interval 9, cylindrical rods 10a, 10b and 10c made of plastic and having a diameter of ⌀8 mm each, a method for applying a hemostatic device 1 containing an element supporting the interval from the paragraphs [1 ]-[four].

Round rods 10a, 10b and 10c, each having a diameter of ⌀8 mm, are connected at equal intervals, as shown in the drawing. Tape 2 is wrapped around the wrist 500 without the application of tensile force. Further, when the round rods 10a, 10b and 10c are disconnected, if the interval between 10a, 10b and 10c is 8 mm, the tape 2 has an attenuation length of about 15 mm.

In the method of using the hemostatic device 1 containing the interval supporting member from paragraph [2] above, the three round rods 10a, 10b and 10c are not disconnected at the same time. For example, the round rod 10a is disconnected, and the balloon 5 is inflated. Some time after the start of the bleeding stop procedure, the round rod 10b is disconnected. Similarly, after some time, the round rod 10c is disconnected. According to this sequence, the degree of pressure can be adjusted step by step.

The diameter, quantity and arrangement of the round rods used as the element supporting the interval 9 is not limited. The diameters of the round rods 10a, 10b and 10c may be different.

An element supporting interval 9 is not limited to a cylindrical rod, and may have any shape that can be placed between the wrist 500 and the hemostatic device 1, such as a rectangular rod, including a cuboid and cubic shape, a round, and a triangular rod, including a truncated cone with a light bias, and other forms.

Example 4

6 is a cross-sectional view showing the hemostatic device of Example 4, including an interval supporting member.

The limiter may have a structure that allows the clamp length to be adjusted step by step.

In the state where the tape 2 is applied for an overlay length of 2.5 mm and fastened by means of the clips 20a, 20b and 20c, the tape 2 is wrapped around the wrist 500 without applying tensile force. Then, when the clips 20a, 20b and 20c are disconnected, the tape has a length of attenuation of about 15-16 mm.

In the method using the hemostatic device 1 containing the interval supporting member from paragraph [2] above, the three clips 20a, 20b and 20c are not disconnected at the same time. For example, the clip 20a is disconnected and the balloon 5 is inflated. After some time from the start of the procedure to stop bleeding, the clamp 20b is disconnected. Similarly, after some time, the clip 20c is disconnected. According to this sequence, the degree of pressure can be adjusted step by step.

The length, number and location of the clips used as the element supporting the interval 9 is not limited. The length of the clips 20a, 20b, and 20c may vary.

A hemostatic device containing an interval supporting member has been described based on the illustrated embodiments. However, it is not limited to these embodiments. Each of the parts that make up the hemostatic device containing the interval-supporting element can be replaced by any other part of the configuration that allows you to perform the same function as the part of the configuration of this utility model. In addition, any configuration items can be added.

A hemostatic device containing an interval supporting element is not limited to use only on the wrist, and can be used as a hemostatic device containing an interval supporting element for attachment and use on any part of a patient’s arm or leg (collectively referred to in this description as “limbs” ").

The illustrated embodiments of the utility model have been described above, although in the light of the above teachings many modifications and variations may be made. Thus, it is necessary to understand that the utility model can be implemented differently than specifically described, without separating from the volume of the claims of the utility model.

By pre-securing the interval supporting member by wrapping the tape around the limb, and detaching the interval supporting member so that the tape has a predetermined attenuation length, the hemostatic device containing the interval supporting member exerts compressive force on the piercing portion by inflating the balloon to stop bleeding, with the establishment of the proper degree of compression in a simple reproducible manner. Thus, the industrial applicability of the present utility model is significant.
