Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a hemostatic device. Background Art

[0002] After the transradial artery coronary intervention, controlling bleeding at the puncture site is a crucial step. Currently, the hemostatic devices used for radial artery interventional puncture points on the market are roughly divided into two types: knob-type hemostats and balloon-type hemostats. These devices try to reduce bleeding at the puncture point of the blood vessel by compressing the puncture point, and achieve hemostasis by sealing the puncture point through the body's own coagulation mechanism.

[0003] In clinical practice, the operator first wears a hemostat in the catheter room, pressurizes to confirm that there is no bleeding, and then moves the patient to the ward. Medical staff regularly check the bleeding at the compression point and adjust the hemostat to increase or reduce pressure. Since the puncture site is compressed for too long after surgery, the occlusion of the artery at the compression site increases, which can cause peripheral ischemia. At the same time, there are also postoperative complications such as inappropriate compression site causing subcutaneous bleeding and insufficient compression causing bleeding at the puncture site, which affects the patient's quality of life score after surgery and delays recovery, causing discomfort to the patient.

[0004] In order to reduce the inappropriate pressure caused by the hemostat, medical staff need to properly adjust the compression hemostat worn by the patient after surgery. The compression adjustment of the knob-type hemostat is that the medical staff operates the knob component on the hemostat to raise and lower the height of the silicone pad at the compression position to adjust the pressure on the patient's wrist. Because the compression position does not avoid blood vessels and nerves well, the pain caused by compression is high. For the airbag hemostat, medical staff need to use an external syringe to extract the air in the airbag to reduce the amount of air in the airbag to reduce the pressure. The process of adjusting the pressure in the airbag is cumbersome and requires an additional syringe. In addition, adjusting the pressure in the airbag to inject air may mistakenly connect other medical devices, inject air into the human body and cause air embolism. In addition, there is a possibility of airbag leakage, resulting in hemostasis failure or bleeding during hemostasis. Summary of the invention

[0005] In order to solve the above-mentioned problems existing in the prior art, an embodiment of the present invention provides a hemostatic device for radial artery compression, which has more concentrated compression on the puncture point, avoiding the abundant blood vessels and nerves in the wrist, making it more comfortable for patients to wear; the gas injection process is eliminated, avoiding the risk of air embolism caused by accidental injection of air into other medical devices, and at the same time avoiding the risk of hemostasis failure or mid-way bleeding due to airbag leakage.

[0007] Optionally, the angle of the pressing plate relative to the supporting plate is adjusted by adjusting the knob to adjust the pressure of the flexible compression component on the radial artery.

[0008] Optionally, the flexible compression assembly includes a first flexible compression component and a second flexible compression component located between the first flexible compression component and the pressure plate.

[0025] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present invention, and are not intended to limit the scope of the present invention. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0026] When used herein, the expressions “having”, “may have”, “including”, and “may include” indicate the presence of corresponding features (e.g., numbers, functions, operations, or constituent elements such as components), and do not exclude one or more additional features.

[0027] The expressions "first", "second", "the first", and "the second" used in various embodiments of the present invention may modify various components (regardless of their order and / or importance), but do not limit the corresponding components. For example, a first device and a second device indicate different devices, but they are both devices. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present invention.

[0028] It should be understood that when an element (e.g., a first element) is represented as being "connected" or "coupled" to another element (e.g., a second element) (operably or communicatively), it may be directly connected or coupled to the other element, or any other element (e.g., a third element) may be interposed therebetween. Conversely, it should be understood that when an element (e.g., a first element) is represented as being "directly connected" or "directly coupled" to another element (the second element), there is no intervening element (e.g., a third element) therebetween.

[0029] As described in the background technology, the advantage of the knob-type hemostat is that it is more convenient for doctors to operate. Its disadvantage is that the compression position does not avoid blood vessels and nerves well, and the pain caused by compression is high. The advantage of the balloon-type hemostat is that it has higher affinity, which is due to the material and design of the compression balloon, which makes the patient feel less pain during compression. Its disadvantage is that the convenience of doctors' operation is reduced. Therefore, there is an urgent need for a hemostatic device that can take into account both convenience and operability.

[0030] To this end, an embodiment of the present invention provides a hemostatic device. The hemostatic device includes: a wristband for wearing on a wrist; a support plate connected to the wristband; a pressure plate located on the inner side of the support plate, and a flexible compression component is provided on the inner side of the pressure plate; and an adjustment knob connected to the pressure plate through the support plate, and the position of the pressure plate is adjusted by the adjustment knob to adjust the pressure of the flexible compression component on the radial artery.

[0032] like Figures 1 to 4 As shown in , the hemostatic device 100 includes a wristband 10, a support plate 20, a pressure plate 30 and an adjusting knob 40. The wristband 10 is used to be worn on the wrist, and the two ends of the support plate 20 are respectively connected to the two ends of the wristband 10 to form an annular structure, the pressure plate 30 is located on the inner side of the support plate 20, and a flexible compression component 31 is provided on the inner side of the pressure plate 30. The adjusting knob 40 passes through the support plate 20 and is connected to the pressure plate 30. The position of the pressure plate 30 is adjusted by adjusting the knob 40 to adjust the pressure of the flexible compression component 31 on the radial artery.

[0033] The flexible compression component 31 may be a component filled with soft material, or may be a component made of soft material. In some embodiments, the flexible compression component 31 may be a balloon component filled with gas or liquid.

[0034] The embodiment of the present invention uses a flexible compression component 31 to more concentratedly compress the puncture point, avoiding the abundant blood vessels and nerves in the wrist, making it more comfortable for the patient to wear; moreover, the embodiment of the present invention uses a flexible compression component 31 to cancel the gas injection process, avoiding the risk of air embolism caused by accidental injection of air into other medical devices, and at the same time avoiding the risk of hemostasis failure or mid-bleeding due to airbag leakage.

[0035] In some embodiments, the flexible compression assembly 31 includes a first flexible compression component 311 and a second flexible compression component 312 located between the first flexible compression component 311 and the pressing plate 30. The first flexible compression component 311 and the second flexible compression component 312 can be fixed to the inner side of the pressing plate 30 by bonding, binding or other means.

[0036] The first flexible compression component 311 and the second flexible compression component 312 may be components filled with soft materials or components made of soft materials. In some embodiments, the first flexible compression component 311 and the second flexible compression component 312 may be balloons filled with gas or liquid.

[0037] The puncture point is compressed by the first flexible compression component 311 , and the first flexible compression component 311 is squeezed by the second flexible compression component 312 , so as to achieve a better compression effect on the puncture point.

[0038] In some embodiments, the size of the first flexible pressing component 311 is larger than the size of the second flexible pressing component 312 . In other embodiments, the size of the first flexible pressing component 311 may be smaller than or equal to the size of the second flexible pressing component 312 .

[0039] In some embodiments, the first flexible pressing member 311 and / or the second flexible pressing member 312 are made of elastic material. In some embodiments, the first flexible pressing member 311 and / or the second flexible pressing member 312 are made of silicone.

[0040] In some embodiments, the outer surface of the first flexible compression component 311 and / or the second flexible compression component 312 is wrapped with a soft material to achieve fit to the compression object and good skin-friendliness.

[0041] In some embodiments, the first flexible compression component 311 and / or the second flexible compression component 312 are leaf-shaped. In other embodiments, the first flexible compression component 311 and / or the second flexible compression component 312 may also be rod-shaped, oblate spherical, or other shapes with thicker compression center and thinner edges, to achieve a pressure distribution effect with high pressure at the compression position and low pressure on the surrounding tissues.

[0042] In some embodiments, the hemostatic device is made of a material with high visibility. Specifically, the wristband 10, the support plate 20, the pressure plate 30 and / or the adjustment knob 40 are made of plastic with rigidity and transparency or a plastic material with equivalent characteristics.

[0043] During use, the height of the pressing plate 30 is adjusted by rotating the adjusting knob 40 and utilizing the threaded structure between the adjusting knob 40 and the supporting plate 20, and the pressure of the first flexible pressing component 311 and the second flexible pressing component 312 on the puncture point is then adjusted by the height of the pressing plate 30. The adjusting knob 40 according to the embodiment of the present invention facilitates operation and solves the problem of cumbersome operation when adjusting the pressure in the airbag in the existing products.

[0044] In some embodiments, the length of the wristband 10 is adjustable. For example, through holes 21 are respectively provided at both ends of the support plate 20, and the two ends of the wristband 10 pass through the through holes 21 and are then fixed by bonding, binding or other means, such as by Velcro or snap fasteners.

[0045] The hemostatic device according to the embodiment of the present invention replaces the existing air bag with a silicone balloon, and combines it with a knob-type pressure adjustment mechanism, so that the product maintains the high comfort advantage of the air bag-type hemostat while having the convenient adjustment advantage of the knob-type radial artery hemostat.

[0046] The flexible compression component according to the embodiment of the present invention exerts more concentrated pressure on the puncture point, avoiding the abundant blood vessels and nerves on the wrist, making it more comfortable for the patient to wear. This is not available in other radial artery hemostat with airbag structure or knob-type radial artery hemostat.

[0047] The flexible compression assembly according to the embodiment of the present invention eliminates the gas injection process, thereby avoiding the risk of air embolism caused by the accidental injection of air into other medical devices, and also avoiding the risk of hemostasis failure or mid-course bleeding due to airbag leakage.
