DETAILED DESCRIPTION
[0027] Set forth below with reference to the accompanying drawings is a detailed description of embodiments of a hemostatic device representing examples of the inventive hemostatic device. Note that since embodiments described below are preferred specific examples of the present disclosure, although various technically preferable limitations are given, the scope of the present disclosure is not limited to the embodiments unless otherwise specified in the following descriptions. Moreover, in the drawings, the same reference signs are assigned to the same components, and detailed descriptions of the same reference signs assigned to the same components are appropriately omitted. In addition, dimensional ratios in the drawings are exaggerated for convenience of explanation, and may be different from the actual ratios.
First Embodiment
[0028]
[0029] For example, the hemostatic device 100 according to the present embodiment can be used to perform hemostasis on a puncture site t1 (hemostatic target site) formed on a radial artery (for example, a distal radial artery extending around a snuff box or to a fingertip side from the snuff box) of a palmar artery (deep palmar artery) extending to a dorsal side Hb of a hand H, for the purpose of inserting a treatment device such as a catheter performing a treatment, an inspection, or the like into a blood vessel of a subject, after removing an introducer indwelling in the puncture site t1. Note that a position where the puncture site t1 is formed may be any site such as a left hand, a right hand, a dorsal side of a hand, or a palm side of a hand. Moreover, the application of the hemostatic device 100 is not limited to only the hemostasis of the puncture site t1 formed on the hand H. For example, the hemostatic device 100 can be used to perform hemostasis on a puncture site formed in an arm of a subject for the purpose of inserting a medical device into a radial artery.
[0030] The hemostatic device 100 includes a hemostatic unit 10 and a securing unit 60, as described with reference to
[0031] Hemostatic Unit
[0032] As illustrated in
[0033] Hemostatic Member
[0034] As illustrated in
[0035] As illustrated in
[0036] The plate-shaped member 50 is attached to the securing unit 60. As illustrated in
[0037] Each of the shaft support members 30 and 40 is configured such that a position of each of the shaft support members 30 and 40 with respect to the plate-shaped member 50 can be secured in a state where the skin around the puncture site t1 is pinched between the first hemostatic member 20a and the second hemostatic member 20b. For example, a securing mechanism for securing each of the shaft support members 30 and 40 to the plate-shaped member 50 can be, for example, a structure using a frictional force, a fitting structure using a groove, a movement/secure structure using a screw, or the like.
Securing Unit
[0038] The securing unit 60 secures the first hemostatic member 20a and the second hemostatic member 20b to the hand H of the subject. As illustrated in
Use Example
[0039] Next, a use example of the hemostatic device 100 according to the present embodiment will be described.
[0040] An operator such as a doctor attaches the securing unit 60 to the hand H of the subject so that the securing unit 60 wraps the hand H in a state where the puncture site t1 is formed on the dorsal side Hb of the hand of the subject and an introducer sheath (not illustrated) is indwelled at the puncture site t1 (refer to
[0041] After the operator removes the introducer sheath, as illustrated in
[0042] The operator pinches the skin around the puncture site t1 between the hemostatic members 20a and 20b. Accordingly, the operator can close the puncture site t1 to locally perform the hemostasis on the puncture site t1 without applying a compressing force to the puncture site t1 as much as possible.
[0043] After the operator completes the hemostasis of the puncture site t1, the operator moves the hemostatic members 20a and 20b so that the hemostatic members 20a and 20b are relatively away from each other, and thus, releases the pinch of the skin around the puncture site t1.
[0044] As described above, the hemostatic device 100 according to the present embodiment includes the first hemostatic member 20a, and the second hemostatic member which can move relatively close to or away from the first hemostatic member 20a and pinches the skin around the puncture site t1 of the subject between the first hemostatic member 20a and the second hemostatic member 20b when the second hemostatic member 20b moves close to or toward the first hemostatic member 20a.
[0045] In the hemostatic device 100, the skin around the puncture site t1 of the subject is pinched between the first hemostatic member 20a and the second hemostatic member 20b, and thus, the hemostasis can be performed on the puncture site t1. Accordingly, the hemostatic device 100 can rather effectively perform the hemostasis on the puncture site t1 without generating over-pressurization compression. In a case where the hemostatic device 100 is used around a palmar artery, a skin of a distal radial artery rather easily stretches and a blood vessel extends at a relatively shallow position. Accordingly, hemostasis can be effectively performed on the site due to the pinch between the first hemostatic member 20a and the second hemostatic member 20b of the hemostatic device 100.
[0046] Moreover, each of the first hemostatic member 20a and the second hemostatic member 20b includes the rotatable roller. Accordingly, the skin around the puncture site t1 is pulled and pinched to be squeezed, and the hemostasis can be locally performed on the puncture site t1.
[0047] Moreover, the hemostatic device 100 includes the securing unit 60 which secures the first hemostatic member 20a and the second hemostatic member 20b to the hand H of the subject. Accordingly, it is possible to rather easily maintain a state where the hemostatic device 100 is secured to the hand H of the subject.
[0048] Moreover, the securing unit 60 is configured to include the band-shaped member which can be attached to the hand H of the subject. Accordingly, the hemostatic device 100 can be rather easily attached to the hand H.
Second Embodiment
[0049]
[0050] As illustrated in
[0051] The securing unit 60a is constituted by a holding member which pinches the hand H of the subject to secure the hemostatic device 100a to the hand H. In the present embodiment, the securing unit 60a has a clip structure which applies a securing force to the hand H by an elastic force, for example, of a material of the securing unit 60a.
[0052] As illustrated in
[0053] In the securing unit 60a, a projection portion 80 projecting in a convex shape toward a side of each of the hemostatic members 20a and 20b is disposed at a position facing the hemostatic members 20a and 20b.
[0054] While the hemostasis is performed on the dorsal side Hb of the hand by the hemostatic members 20a and 20b, the projection portion 80 applies a pressing force from a palm side. Accordingly, it is possible to prevent the hemostatic device 100a from being displaced in a state where the hemostatic device 100a is secured to the hand H.
[0055] The projection portion 80 can be configured to be attached to or detached from the securing unit 60a. For example, as illustrated in
[0056] Note that the projection portion 80 can be attached to the securing unit 60 (refer to
[0057] As described above, the hemostatic device 100a according to the present embodiment comprises the holding member in which the securing unit 60a pinches the hand H to secure the hemostatic device 100a. Accordingly, the hemostatic device 100a can be rather easily mounted on the hand H of the subject and secured to the hand H. Moreover, unlike the band-shaped member, the securing unit 60a is not disposed along the entire outer periphery of the hand H. Accordingly, a degree of freedom of the hand H of the subject increases while the hemostasis is performed. Moreover, unlike a glove, the hemostatic device 100a is not disposed so as to cover the entire hand H. Accordingly, it is possible to prevent the subject from feeling uncomfortable due to the hand H becoming hot and stuffy.
[0058] Moreover, the securing unit 60a is configured to include the projection portion 80 on the side opposite to the portions where the first hemostatic member 20a and the second hemostatic member 20b are disposed. Accordingly, it is possible to stably maintain the state where the hemostatic device 100a is secured to the hand H of the subject while the hemostasis is performed by the first hemostatic member 20a and the second hemostatic member 20b.
[0059]
[0060] As illustrated in
[0061] As illustrated in
Third Embodiment
[0062]
[0063] As illustrated in
[0064] The shaft support members 30 and 40 are movably attached to the plate-shaped member 50, and as illustrated in
[0065] The arm portion 90 pinches the skin around the hemostatic target site t1 from the outside of the first hemostatic member 20a and the second hemostatic member 20b. In the present embodiment, the arm portion 90 may be a curved flat plate member. Note that a specific shape, a material of the arm portion, or the like of the arm portion 90 is not limited.
[0066] As illustrated in
Fourth Embodiment
[0067]
[0068] In the hemostatic device according to the fourth embodiment, a convex portion 21 is formed on the first hemostatic member 20a by a roller. Further, the convex portion 21 is also formed on the second hemostatic member 20b composed of a roller. The convex portion 21 is formed in a portion of each of the hemostatic members 20a and 20b in a circumferential direction of the hemostatic members 20a and 20b, and projects outward of each of the hemostatic members 20a and 20b in a radial direction of the hemostatic members 20a and 20b.
[0069] The convex portion 21 is formed along the entire longitudinal direction of each of the hemostatic members 20a and 20b. Moreover, the convex portion 21 is integrally formed with each of the hemostatic members 20a and 20b.
[0070] As illustrated in
[0071]
Fifth Embodiment
[0072]
[0073] As illustrated in
[0074] The first hemostatic member 20g, the second hemostatic member 20h, and the third hemostatic member 20j are configured to be movable not in one direction but in a radial direction, as illustrated in
[0075] The support member 30a may be a bent plate-shaped member which supports the first hemostatic member 20g, the second hemostatic member 20h, and the third hemostatic member 20j.
[0076] Each of the hemostatic members 20g, 20h, and 20j is connected to the string-shaped operation member 40a. When the operation member 40a is operated to be gripped and pulled, the hemostatic members 20g, 20h, and 20j move relatively close to each other. Further, when the pulling is released, the operation member 40a moves the hemostatic members 20g, 20h, and 20j so that the hemostatic members 20g, 20h, and 20j are moved relatively away from each other. When the operator operates the operation member 40a so that the hemostatic members 20g, 20h, 20j are close to each other, a skin near a center position when the hemostatic members 20g, 20h, 20j are close to each other is pinched. Accordingly, it is possible to locally perform hemostasis on the puncture site.
[0077] Hereinbefore, as described in the present modification example, the number of hemostatic members provided in the hemostatic device is not limited to two. Further, a method of pinching the skin by the hemostatic members is not limited to the method using the roller.
Other Hemostatic Methods
[0078] In a hemostatic method using the hemostatic device according to the present disclosure, for example, an embolization material or the like can be used together with the hemostatic device. Hereinafter, an example of the hemostatic method will be described.
[0079] For example, as illustrated in
[0080] Moreover, for example, as illustrated in
[0081] In addition, for example, as illustrated in
[0082] The operator can rather effectively increase the hemostasis effect by applying the embolization material k according to each method described above and then performing the hemostasis using the hemostatic device. According to the method illustrated in
[0083] Hereinbefore, the hemostatic device according to the present disclosure is described through the embodiments. However, the present disclosure is not limited to each of the described configurations, and can be appropriately modified based on descriptions in claims.
