Description

Technical Field

[0001] This invention relates to a hemostatic device after puncture surgery, and more particularly to a puncture site hemostatic compression device using a balloon. Background Technology

[0002] Currently, after arterial and venous punctures (such as radial artery and femoral artery puncture and catheterization), pressure bandaging is required at the puncture site to prevent bleeding. Clinically, elastic bandages or mechanical compression devices are routinely used for varying durations, relying on regular rounds by medical staff or patient complaints to detect bleeding. At night, patients are asleep and it is inconvenient to frequently lift the blankets. The blankets also obscure the femoral artery and vein wounds, making it difficult to observe the bleeding point. This method results in delayed bleeding detection, and early oozing is not easily detected, presenting the following drawbacks:

[0003] It is easily absorbed by dressings, making it difficult to detect in appearance. Accumulated blood loss, hematoma formation, and even compression of nearby nerves and blood vessels may occur.

[0004] It requires a lot of manpower, and multiple check-ups are needed within 24 hours after the operation, which increases the workload of medical staff.

[0005] Traditional puncture compression therapy in clinical practice uses elastic bandages or disposable, spirally adjustable plastic compression methods to stop bleeding at arterial / venous puncture sites. However, this involves empirically controlling the pressure, which lacks intuitiveness; it also results in poor patient comfort and experience. In an effort to prevent bleeding, "over-compression" can occur, leading to complications such as limb pain, numbness, radial artery occlusion, venous compression, and blisters due to high skin tension.

[0006] In summary, the main problem at present is:

[0007] In the current technology, mechanical compression devices are used to perform puncture point compression operations, but the effect is not good, the patient's comfort is poor, and the compression is unstable and unreliable. Summary of the Invention

[0008] The purpose of this invention is to provide a puncture point hemostasis and compression device using an airbag pressurization system, which can perform stable and reliable puncture point compression operations.

[0009] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0013] Furthermore, the airbag has an air nozzle for inflating the airbag using an air pump.

[0014] Furthermore, the puncture point hemostasis and pressure device also includes a bleeding detection sensor, which is installed on the airbag.

[0015] Furthermore, the blood leakage detection sensor is a liquid sensing sensor or a blood sensing sensor.

[0016] Furthermore, the airbag is disposed on the skin-proximity side of the substrate, and its specific structural form is as follows: the puncture point hemostasis pressing device further includes a pressing adjustment mechanism, the pressing adjustment mechanism is mounted on the substrate, the airbag is mounted on the pressing adjustment mechanism and is located on the skin-proximity side of the substrate, and the pressing adjustment mechanism can press the airbag toward the human body based on the substrate.

[0017] Furthermore, the pressing adjustment mechanism includes a tightening bolt and a lower pressure plate. The lower pressure plate is disposed on the side of the substrate near the skin surface. The tightening bolt passes through the substrate, with the tightening end of the tightening bolt located on the side of the substrate near the skin surface and the head of the tightening bolt located on the top surface of the substrate. The threaded portion of the tightening bolt is threadedly fitted to the substrate. On the side of the substrate near the skin surface, the tightening end of the tightening bolt is rotatably connected to the lower pressure plate. The airbag is disposed on the lower pressure plate.

[0018] Furthermore, the airbag is disposed on the skin-friendly side of the substrate, and its specific structural form is: the airbag is directly disposed on the skin-friendly side of the substrate.

[0019] Furthermore, the limb binding mechanism is specifically implemented as follows: the puncture point hemostasis and pressure device further includes a binding strap, loops are provided on both sides of the base plate, the binding strap is mounted on one loop, and thus is set on one side of the base plate; the binding strap is provided with a pair of male and female Velcro fasteners, which can be used in conjunction with the loop on the other side of the base plate, so that the binding strap can be connected and tightened on the loop on the other side.

[0020] The main advantages of the air-cushioned puncture point hemostasis compression device of the present invention compared with the prior art are as follows:

[0027] The following provides further details on specific embodiments of the present invention:

[0028] Implementation method 1:

[0029] This embodiment 1 provides a puncture point hemostasis and compression device using an airbag pressurization. This puncture point hemostasis and compression device is used to apply stable pressure to the puncture point after puncture surgery to prevent bleeding at the puncture point.

[0030] See Figure 1 , Figure 2 and Figure 3 The puncture point hemostasis and compression device of this embodiment 1 includes a base plate 1, a binding strap 2, and an air bladder 5.

[0031] The binding strap 2 is provided on one side of the substrate 1.

[0032] Specifically

[0033] The substrate 1 is rectangular in shape, and loops 11 are fixedly provided on both sides of the substrate 1. The binding strap 2 is assembled on one of the loops 11, thus being located on one side of the substrate 1. The binding strap 2 is provided with a pair of male and female hook and loop fasteners 21, which can be used with the loop 11 on the other side of the substrate 1, so that the binding strap 2 can be connected to and tightened on the loop 11 on the other side.

[0034] It should be noted that the male and female hook and loop fastener pair 21 is a commonly used hook and loop fastener structure. It essentially consists of two hook and loop fasteners, male and female, spaced apart (for easy tightening). Its main purpose is to wrap around the connecting loop 11 and also provides a tightening effect. This is a commonly used binding connection method; many blood pressure monitor cuffs currently use this structure, making it easy to tighten the cuff.

[0035] For ease of accurate description, the side of substrate 1 facing the human body is referred to as the "skin-facing side". Figure 3 The side of substrate 1 facing away from the human body (as shown in the diagram) is referred to as the "top surface" (the side facing away from the human body). Figure 1 (One side shown in the image).

[0036] The airbag 5 is fixedly disposed on the skin-like surface of the substrate 1, that is, the airbag 5 is fixedly disposed on the skin-like surface of the substrate 1.

[0037] The airbag 5 has a conventional air nozzle 51, through which the airbag 5 can be inflated to increase the air pressure inside the airbag 5. In this embodiment 1, the air nozzle 51 adopts a structure similar to an American tire valve, which is a conventional device. It can be inflated and deflated by pressing the valve core. A conventional air pump can be used to inflate the air nozzle 51.

[0038] In this embodiment 1, a hole is provided on the substrate 1 for the air nozzle 51 of the airbag 5. The air nozzle 51 passes through the hole and protrudes at the top surface of the substrate 1, which facilitates the inflation of the air nozzle 51.

[0039] A small pressure gauge 52 is also provided for the airbag 5. The pressure gauge 52 is located on the top surface of the substrate 1. The air inlet of the pressure gauge 52 passes through the substrate 1 and is connected to the airbag 5. In this way, the air pressure inside the airbag 5 can be observed through the pressure gauge 52.

[0040] In addition, a medical dressing 6 is provided on the airbag 5. The medical dressing 6 has soft and skin-friendly properties. When the airbag 5 applies pressure to the puncture point on the human body surface, the medical dressing 6 is directly attached to the puncture point. It can relieve the pain at the puncture point and keep the puncture wound dry and sterile.

[0041] The specific usage method and functional principle of the puncture point hemostasis compression device in Embodiment 1 are as follows:

[0042] The hemostatic pressure device is worn at the puncture point of the patient. The binding strap 2 is passed through the loop 11 on the other side of the base plate 1 and tightened. The male and female Velcro pairs 21 on the binding strap 2 are glued together, thereby positioning the base plate 1 at the puncture point of the patient. The air bladder 5 on the skin surface of the base plate 1 forms a pressing posture on the puncture point.

[0043] The airbag 5 is inflated using an existing air pump. The inflation process needs to be slow, and the pressure gauge 52 is observed while inflating. The air pressure inside the airbag 5 is controlled according to the required pressure. When the air pressure inside the airbag 5 reaches the target value, inflation is stopped. At this time, the airbag 5 applies a certain amount of pressure to the puncture site, thereby achieving the purpose of "pressing down the puncture site to prevent bleeding".

[0044] When the airbag 5 is pressed against the puncture site, the medical dressing 6 set on the airbag 5 is directly attached to the puncture site, relieving the wearer's pain and keeping the puncture wound sterile.

[0045] When a patient experiences discomfort at the puncture site, or limb pain, numbness, or abnormal skin color and temperature, the pressure applied can be reduced in two ways:

[0046] 1) Release the gas in the airbag 5 by releasing air through the air nozzle 51 until the air pressure displayed on the pressure gauge 52 reaches the target value;

[0047] 2) Adjust the binding force of the binding strap 2 until the air pressure displayed on the pressure gauge 52 reaches the target value.

[0048] It should be noted that the loop 11 mentioned earlier is fixedly mounted on two opposite sides of the substrate 1.

[0049] It should be noted that the structure in which the binding strap 2 and loop 11 cooperate is essentially a limb binding mechanism. In other embodiments, other forms of limb binding mechanisms can be used to replace the structure in which the binding strap 2 and loop 11 cooperate, such as using an elastic bandage. As long as it can achieve the goal of "the patient can wear the base plate 1 on the puncture point on the body, and the skin-proximal surface of the base plate 1 can stably press the airbag 5 against the puncture point, forming a pressing posture on the puncture point", it is acceptable.

[0050] The main advantage of the puncture point hemostasis compression device in Embodiment 1 is that:

[0051] 1) The puncture point hemostasis and pressure device of this embodiment 1 is equipped with an air bag 5. The air bag 5 is used to apply pressure to the puncture point of the patient. Compared with the traditional mechanical pressure device, the air bag 5 can increase the patient's comfort, reduce the occurrence of blisters on the skin, and has a closer fit with the patient's skin. Even if the patient changes his sleeping posture involuntarily at night, the pressure point will not easily shift, and the pressure is more stable.

[0052] In addition, the puncture point hemostasis compression device of Embodiment 1 has other advantages, as follows:

[0053] 2) The puncture point hemostasis and pressing device of Embodiment 1 is used to perform the puncture point pressing operation. The operation process is simple and convenient. The base plate 1 can be firmly positioned at the puncture point and is not easy to fall off. Based on the stable and reliable support of the base plate 1, the airbag 5 can apply stable and reliable pressing to the puncture point.

[0054] Implementation Method 2:

[0055] This embodiment 2 provides a puncture point hemostasis and compression device. The basic concept of this puncture point hemostasis and compression device is basically the same as that of the puncture point hemostasis and compression device provided in embodiment 1. It also uses an airbag 5 to perform compression operation on the puncture point. The main difference is that the puncture point hemostasis and compression device of this embodiment 2 is equipped with a bleeding alarm function.

[0056] Specifically, see Figure 4 ,

[0057] In the puncture point hemostasis and compression device of this embodiment 2, a bleeding detection sensor 71 is also provided in the middle of the airbag 5 (the part where compression is performed). The bleeding detection sensor 71 adopts the liquid sensing sensor of the prior art. A miniature audible and visual alarm 73 is also configured for the bleeding detection sensor 71. The audible and visual alarm 73 is connected to the bleeding detection sensor 71 through the communication cable 72 of the prior art.

[0058] The blood leakage sensor 71 can detect blood as a liquid. When using the puncture point hemostasis compression device of this embodiment 2 to perform puncture point compression, the blood leakage sensor 71 on the airbag 5 is attached to the puncture point. When there is bleeding at the puncture point, the blood leakage sensor 71 can detect the blood and transmit the sensing signal to the audible and visual alarm 73 through the communication cable 72. After receiving the signal, the audible and visual alarm 73 will emit an audible and visual alarm signal. The combination of the blood leakage sensor 71 and the audible and visual alarm 73 realizes the blood leakage alarm function, so that medical staff can be informed of the patient's abnormal condition at the first time and take timely measures to prevent the condition from deteriorating.

[0059] It should be noted that the blood seepage detection sensor 71 can also be a blood sensing sensor of existing technology, which was developed by the Department of Electrical Engineering of Southern Taiwan University of Science and Technology. Its structure and technical characteristics have been published in a public journal.

[0060] Implementation Method 3:

[0061] This embodiment 3 provides a puncture point hemostasis compression device, the basic concept of which is basically the same as the puncture point hemostasis compression device provided in embodiment 1.

[0062] The main difference is:

[0063] 1) Airbag 5 no longer has an air valve; it is a completely sealed unit.

[0064] 2) A pressure adjustment mechanism is configured for the airbag 5. The pressure adjustment mechanism is set based on the base plate 1. The airbag 5 is installed based on the pressure adjustment mechanism. The pressure adjustment mechanism can press the airbag 5 towards the human body, thereby adjusting the pressure of the airbag 5 on the puncture point.

[0065] More specifically, see Figure 5 ,

[0066] In the puncture point hemostasis and pressure device of this embodiment 3, two tightening bolts 81 and a lower pressure plate 82 are provided. The lower pressure plate 82 is located on the skin side of the base plate 1. The two tightening bolts 81 are inserted into the base plate 1 and pass through the base plate 1. The tightening end of the tightening bolt 81 is located on the skin side of the base plate 1, and the head of the tightening bolt 81 is located on the top side of the base plate 1. The threaded part of the tightening bolt 81 is assembled with the base plate 1, and the two are threadedly engaged. On the skin side of the base plate 1, the tightening ends of the two tightening bolts 81 are both assembled and connected to the lower pressure plate 82, and the connection between the two is a rotatable connection. In this way, the lower pressure plate 82 can be controlled to be raised and lowered by rotating the two tightening bolts 81.

[0067] In this embodiment 3, the airbag 5 is no longer directly connected and assembled with the base plate 1, but is fixedly mounted on the lower pressure plate 82. In this way, based on the lifting and pressing action of the lower pressure plate 82, the pressing operation of the puncture point can be realized, and the pressing force can be adjusted.

[0068] The two tightening bolts 81, together with the lower pressure plate 82, constitute the pressing adjustment mechanism. In other embodiments, other forms of pressing adjustment mechanisms may also be used.

[0069] The biggest advantage of the puncture point hemostasis compression device in Implementation Method 3 is that:

[0070] When performing pressure on the puncture site, the airbag 5 can be used to press on the puncture site by adjusting the tightening bolt 81. The pressure can be adjusted at any time. Medical staff only need to instruct the patient to pay attention to the reading of the pressure gauge 52 and keep the pressure gauge value within a certain range. If the value is lower or abnormal, the medical staff should be notified to adjust the pressure so that the reading of the pressure gauge 52 meets the target value. The operation is simple and convenient, and there is no need for medical staff to use an air pump to inflate the airbag on site to adjust the pressure.

[0071] Regarding the puncture point hemostasis and pressure device in Implementation 1, the air pump pressurizes the balloon to solve the problem of immediate pressure hemostasis after the patient's operation; while the puncture point hemostasis and pressure device in Implementation 3 solves the problem of rapid handling of abnormal situations after the patient returns to the ward after the operation by manually applying pressure. Both methods are more suitable for different clinical scenarios and provide more comprehensive protection for the safety of the patient's puncture wound.

[0072] It should be noted that since the airbag 5 is movable relative to the base plate 1, the relative position between the pressure gauge 52 on the base plate 1 and the airbag 5 is also not fixed. In order to adapt to this situation, a gas guiding hose 53 is provided between the airbag 5 and the pressure gauge 52, and the two are connected together through the gas guiding hose 53. The pressure gauge 52 can then detect the air pressure inside the airbag 5 normally.

[0073] It should be noted that, based on the concept of this embodiment 3, an air nozzle can also be provided for the airbag 5. Combining the two aspects can complement each other.

[0074] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
