Description

Technical Field

[0001] The utility model relates to a hemostatic device for wounds, in particular to a rapid hemostatic device suitable for surgical puncture wounds of the distal radial artery of the wrist. Background Art

[0002] The distal radial artery procedure has been proposed, which is to use the distal radial artery at the radial fossa at the back of the wrist as a puncture entrance for treatment, which has the advantages of minimal invasion and few complications. The local hemostasis method generally used for the puncture entrance includes bandage binding, or compression hemostasis with an inflatable or spiral compression hemostat.

[0003] However, bandages, inflatable or spiral compression hemostats all require a certain amount of time to fully compress the wound, and cannot provide immediate and direct pressure to the wound to achieve hemostasis after surgery. Furthermore, these methods are not easy to fine-tune and reduce the applied pressure during the hemostasis and healing stage, which can easily cause forearm swelling and numbness in patients.

[0004] Therefore, there is a need for a hemostatic device suitable for surgical puncture wounds of the distal radial artery, which can be fixed on the patient's wrist to quickly compress and stop bleeding on the radial artery puncture wound, and can easily fine-tune the applied pressure to reduce patient discomfort.

[0022] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0023] Please refer to Figure 1 , Figure 1 The figure shows a cross-sectional view of a hemostatic device according to an embodiment of the present invention. Figure 1 As shown, in one embodiment of the utility model, a hemostatic device 100 is disclosed, which includes a pressurizing device 110 and a fixing belt 120. The pressurizing device 110 is used to correspond to the wound area 200. The pressurizing device 110 includes an annular base 111, a limiting sleeve 113 and a pressurizing element 114. The annular base 111 has a through hole 112. The limiting sleeve 113 is arranged in the through hole 112 of the annular base 111, and the inner wall of the limiting sleeve 113 has at least one elastic buckle 1131. The pressurizing element 114 includes a wound pad 1141, a one-way sliding screw 1142 and a pressing portion 1143. The wound pad 1141 is used to correspond to the wound area 200. The one-way sliding screw 1142 has a one-way thread 1142a and the one-way thread 1142a is arranged in the limiting sleeve 113. The one-way sliding screw 1142 is screwed with the elastic buckle 1131 by the one-way thread 1142a, and one end of the one-way sliding screw 1142 is connected to the wound pad 1141; the pressing portion 1143 is arranged at the other end of the one-way sliding screw 1142 relative to the wound pad 1141, and the pressing portion 1143 is used to apply pressure to control the pressure element 114 to move or rotate unidirectionally toward the wound area 200, and fine-tune the degree of pressure. The fixing belt 120 is connected to the annular base 111 of the pressure device 110 to fix the hemostasis device 100 at the wound area 200.

[0024] Please refer to Figure 2 , Figure 2 The figure shows a schematic diagram of a pressurizing element and a limiting sleeve of a hemostatic device according to an embodiment of the present invention and a partial enlarged diagram of a unidirectional thread. Figure 2As shown, in the hemostatic device 100 of one embodiment of the utility model, the unidirectional thread 1142a of the unidirectional sliding screw 1142 is a sawtooth thread, and the sawtooth thread has an inclined thread angle Ɵ on one side of the wound pad 1114. The thread angle Ɵ is between 15° and 50°. By means of the unilaterally inclined thread angle Ɵ, the pressure element 114 can move directly toward the wound area 200 after being pressed on the pressing portion 1143, and can be blocked by the elastic buckle 1131 of the limiting sleeve 113 without sliding in the reverse direction, thereby providing pressure to the wound area 200 to stop bleeding. When the wound enters the hemostatic healing stage, the pressure element 114 screwed to the elastic buckle 1131 can be moved away from the wound area 200 by rotating the pressing portion 1143, and the applied pressure can be finely adjusted to reduce the pressure, so that the patient will not feel uncomfortable due to excessive pressure time.

[0025] In the hemostatic device of one embodiment of the present invention, the wound pad 1141 is a rubber pad or a foam material pad, which can provide sufficient pressure to the wound area 200 without being easily deformed during the pressure application process, and will not cause discomfort to the wound area 200 due to excessive hardness.

[0026] Please refer to Figure 3 , Figure 3 The cross-sectional view of another embodiment of the hemostatic device of the present invention is shown. Figure 3 As shown, in another embodiment of the hemostatic device 300 of the present invention, it further comprises an absorption pad 1144. The absorption pad 1144 is disposed on a side of the wound pad 1141 for contacting the wound area 200 to absorb a small amount of blood or tissue fluid exuded from the wound.

[0027] In another embodiment of the hemostatic device of the present invention, the absorbent pad 1144 is permanently (i.e., non-detachably) connected to the wound pad 1141, or temporarily (i.e., detachably) connected to the wound pad 1141. For example, the wound pad 1141 and the absorbent pad 1144 are directly bonded with an adhesive, or the absorbent pad 1144 is temporarily fixed to the wound pad 1141 with an electrostatic adsorption layer, Velcro, etc., so that the absorbent pad 1144 can be directly replaced later. The absorbent pad 1144 includes, but is not limited to, gauze, hemostatic cotton, or foam dressing, and only needs to be soft and absorbent, and does not affect the pressure applied by the wound pad 1144 to the wound area 200.

[0028] Please refer to Figure 4 , Figure 4 The figure shows a cross-sectional view of a fixing belt of a hemostatic device according to an embodiment of the present invention. Figure 4As shown, in another embodiment of the hemostatic device of the present invention, the fixing belt 420 includes a base material 421 and an attachment layer 422. The attachment layer 422 is a Velcro or adhesive layer, so that the hemostatic device can be wrapped or attached to the wound of the wrist by the fixing belt 420. The base material 421 is preferably a flexible and non-extensible base material, such as a flexible paper fiber non-woven fabric or a polymer fiber non-woven fabric, so as to be adhered to and fixed to the irregular surface of the limb around the wound area 200, and has a low extensibility to avoid the pressure being gradually reduced or the pressurizing device 110 being loosened due to the extension of the base material 421 during the pressurization process.

[0029] The hemostatic device of the utility model includes a pressurizing device and a fixing belt. The pressurizing device includes an annular base, a limiting sleeve and a pressurizing element. In the pressurizing element, a unidirectional sliding screw is screwed with at least one elastic buckle by a unidirectional thread to fine-tune the pressurization degree and ensure stability. After the hemostatic device of the utility model is fixed to the patient's wrist, it can quickly compress and stop bleeding on the radial artery puncture wound, and it is easy to fine-tune the applied pressure to reduce the patient's discomfort.

[0030] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
