Description

Technical Field

[0001] This utility model relates to the technical field of radial artery pressure hemostasis equipment, and in particular to a radial artery pressure hemostasis device. Background Technology

[0002] Currently, various arterial or deep vein punctures and catheterizations are frequently required in clinical practice, especially for conditions such as aneurysms and arterial stenosis.

[0003] During interventional therapy, it is necessary to puncture an artery and place a catheter. There are two puncture approaches: the femoral artery and the radial artery. However, femoral artery puncture has many inconveniences and disadvantages.

[0004] However, the radial artery is better suited for obtaining arterial blood samples or performing cardiovascular interventional procedures. Sometimes it is also used for critically ill patients.

[0005] Arterial blood should be collected frequently, with radial artery sampling being the preferred method. In the absence of auxiliary compression devices, gauze is typically used after arterial puncture.

[0006] Apply pressure bandage.

[0007] Two people are needed: one person presses on the upper part of the artery, and the other person performs the compression. The person pressing on the upper part should continue to compress for 10 to 15 minutes.

[0008] A clockwork motion is used to enhance hemostasis. Manual pressure hemostasis typically requires continuous pressure from medical personnel, and controlling the pressure and duration is difficult.

[0009] There is often a shortage of medical staff, and the latter part of the chest compressions is mostly performed by the patients. However, some patients do not apply sufficient pressure.

[0010] If the pressure is applied too lightly, misaligned, or for too short a duration, or if some patients have poor coagulation function, the pressure may not be effective, leading to oozing or bleeding.

[0011] Swelling can cause bruising in the arm, requiring secondary pressure application, which is time-consuming, laborious, and adds extra burden to the patient; it can also damage the skin and blood vessels.

[0012] This will further complicate the next blood collection, so bleeding should be stopped immediately after the puncture, and appropriate pressure should be applied to reduce bleeding.

[0013] It promotes healing of the puncture site and reduces the risk of complications.

[0014] A search revealed that application number 202323132944.8, entitled "Radial Artery Pressure Hemostasis Device," states: "

[0030] In summary,

[0015] The radial artery pressure hemostasis device provided in this embodiment has a first support member 4 on the wristband 3, and the first support member 4 is perpendicular to the user's wrist.

[0016] The wristband 3 makes point contact with the user's wrist, avoiding large-area contact between the wristband 3 and the user's wrist, thus preventing the wristband 3 from making contact with the user's wrist.

[0017] Applying pressure around the entire wrist provides space for microcirculation, ensuring normal venous blood return and preventing pressure damage to the wrist.

[0018] "Injury." It did not take into account the differences in size resulting from variations in the circumference, body size, and fat layer at the puncture site among different patients. Furthermore, the movement...

[0019] A deviation in the pulse course (such as a reversed pulse) can cause a significant deviation between the pressure point and the support point on the lower side of the arm, resulting in a large deviation from the arm's central axis, which can easily lead to problems with pressure.

[0020] Improper pressure angle can lead to misalignment of the entire pressure surface. Furthermore, if the adjustability of the pressure applied is not considered, it can cause discomfort to the patient.

[0021] The ability to make fine adjustments can lead to a sudden drop in pressure during adjustments, which may affect the hemostatic effect.

[0022] Therefore, there is an urgent need to improve existing radial artery compression bandaging devices to ensure effective compression while increasing ease of clinical operation.

[0023] It improves speed and reliability, enhances patient comfort, and achieves reliable hemostasis. Utility Model Content

[0094] The height allows for different degrees and directions of curvature, enabling it to match the lower forearm dimensions of different patients and ensure the lower forearm surface...

[0095] Stability during the pressing process. Additionally, the upper ends of the inner and outer curvature adjustment components can be respectively fitted and connected to or sleeved onto the adjustable support.

[0096] When fitting the lower and higher sides of plate 4-1, a sleeve 4-6 or a collar 4-7 should be installed.

[0098] The lower surface has a hole through which the support screw 4-3 passes. The inner curvature adjustment component, the middle curvature adjustment component, and the outer curvature adjustment component may all contain...

[0099] The same structure. Its installation method can be as follows: the support rod 4-2 can be fixed or hinged to the upper end of the support screw 4-3, and the lower part can be hinged to it.

[0102] The clamping nut 4-4 and the lower clamping plate 1-3 have holes at the positions where the inner curvature adjustment component, the middle curvature adjustment component, and the outer curvature adjustment component are installed.

[0103] The support screw 4-3 is inserted into the corresponding hole in the lower clamping plate 1-3. A lower clamping device is then installed below the lower clamping plate 1-3, with the middle of the support screw 4-3 positioned below it.

[0104] With nuts 4 and 5 in place, the installation of the inner curvature adjustment component is complete. Next, install the outer curvature adjustment component, following the same process as the inner curvature adjustment component.

[0105] Then install the central curvature adjustment component, as shown in Example 1 below: place the support rod 4-2 of the central curvature adjustment component under the adjustable plate 4-1.

[0106] Inside the sleeve 4-6 on the side, flip the support rod 4-2 so that the threaded hole faces downward, aligning it with the hole on the lower surface of the sleeve 4-6 for the support screw 4-3 to pass through.

[0107] Screw the support screw 4-3 into the support bracket 4-2, then install an upper clamping nut 4-4 in the middle of the support screw 4-3, and then tighten the support screw...

[0110] When the lower surface of the adjustable support plate 4-1 is provided with a collar 4-7, it is fitted with a support rod 4-2 from the central curvature adjustment component, and the collar 4-7...

[0111] The quantity is 1-4 pieces. The installation process of the middle curvature adjustment component in Embodiment 2 is as follows: The support rod 4-2 is fixed to the support screw 4-3.

[0113] 4-2 Insert the collar 4-7 into the lower side of the adjustable support plate 4-1, then use a tool to bend the collar 4-7 inwards to make it vertical, and screw the support screw 4-3 in.

[0114] Inside the support rod 4-2, first install an upper clamping nut 4-4 in the middle of its support screw 4-3, and then insert the support screw 4-3 into the lower...

[0115] In the corresponding holes of clamping plates 1-3, the middle of the support screw 4-3 is located below the lower clamping plate 1-3. Then, a lower clamping nut 4-5 is installed, completing the middle clamping process.

[0116] Installation of the curvature adjustment components. Next, install the outer and inner curvature adjustment components; the installation process and part of the middle curvature adjustment component...

[0117] The process is the same. Embodiment 1 of the U-shaped pressing device 1 includes a U-shaped pressure clamp and a pressure adjusting connector 2, wherein the pressure adjusting connector 2 includes pressure adjusting bolts 2-2.

[0118] The U-shaped pressure clamp has an adjusting bolt 2-2 running through its middle, and the adjusting bolt 2-2 extends out of the threaded side of the U-shaped pressure clamp and is connected to an adjusting nut 2-1.

[0119] Press nut 2-1. The U-shaped pressure clamp is an integral structure, with the two ends after bending in the middle set in parallel, serving as the upper clamping plate 1-2 and the lower clamping plate 1-3 respectively.

[0120] The opening of the U-shaped compression device 1 engages with the front end of the arm, and the radial artery 5 is compressed by the opposing compression protrusions 3-1 and the adjustable support plate 4-1.

[0121] The arm at the puncture site is clamped along the upper and lower sides, applying pressure to the puncture site for a certain period of time to achieve hemostasis. During the clamping process,

[0122] Adjusting the pressure adjusting nut 2-1, which, in conjunction with the pressure adjusting bolt 2-2, adjusts the degree of convergence of the upper clamping plate 1-2 and the lower clamping plate 1-3. This is achieved through the upper clamping...

[0123] The elastic deformation of plates 1-2 and lower clamping plates 1-3 allows for adjustable distance between the pressing protrusions 3-1 and the adjustable support plate 4-1 on their inner surfaces.

[0124] When applying pressure to the latter half of the hemostasis phase, if the patient feels the need to reduce the clamping force, the nursing staff can loosen the pressure adjusting nut 2-1 slightly.

[0125] The adjustment is relatively uniform, and sudden drops are not likely to occur.

[0126] Embodiment 2 of the U-shaped pressing device 1 includes an upper clamping plate 1-2, a lower clamping plate 1-3, a U-shaped elastic element 1-1, and a pressure adjusting connector 2, wherein...

[0127] The pressure adjusting connector 2 includes a pressure adjusting bolt 2-2 and a pressure adjusting nut 2-1. One end of the upper clamping plate 1-2 and the lower clamping plate 1-3 are respectively connected to the U-shaped elastic element 1-1.

[0128] One end is fixedly connected, and a pressure adjusting bolt 2-2 passes through the middle of the upper clamping plate 1-2 and the lower clamping plate 1-3. The pressure adjusting bolt 2-2 extends out of the upper clamping plate 1-2 and...

[0129] The threaded side of the lower clamping plate 1-3 is connected to an adjusting nut 2-1. Its bent portion can be replaced with a U-shaped elastic element 1-1.

[0130] After fixing the upper clamp 1-2 and the lower clamp 1-3, keep them in a state where the opening angle can be changed.

[0131] One embodiment of the pressing component 3 is as follows: The pressing component 3 includes a pressing protrusion 3-1, a positioning post 3-2, and an angle positioning rod 3-3.

[0132] 3-1 Angle positioning rod 3-3 is vertically connected via positioning post 3-2. The outer circumference of angle positioning rod 3-3 and upper clamping plate 1-2 are both equipped with interlocking features.

[0133] The annular toothed groove 3-4. The upper side is connected to the middle of the angle positioning rod 3-3 via the positioning pin 3-2, and the annular toothed groove 3-4 on the angle positioning rod 3-3.

[0134] The annular toothed groove 3-4 on the upper clamping plate 1-2 is tightly fitted together, and the annular toothed groove 3-4 on the angle positioning rod 3-3 can be inserted from the upper clamping plate 1-2.

[0135] Pull it out from the tooth socket. The pressing protrusion 3-1 can be rotated along the circumferential surface of the arm during pressing to adapt to different patients. The radial artery 5 is distributed along the circumferential surface of the arm.

[0136] Different angles result in varying pressing inclinations. Furthermore, the curvature adjustment of the adjustable support plate 4-1 can also be coordinated with the pressing direction of the pressing protrusion 3-1.

[0137] The direction of the pressing protrusion 3-1 can be set to multiple directions, such as setting the direction of the pressing protrusion 3-1 perpendicular to the radial artery 5, or...

[0138] The volume of the pressing bump 3-1 can be increased, or it can be designed as multiple small volumes arranged side by side. The size of the pressing bump 3-1 can be adjusted to accommodate nearby objects.

[0139] The size and shape of an adult's thumb allow for complete coverage and pressure on the radial artery puncture site, easily covering the puncture site and skin penetration.

[0140] The distance difference d between the puncture sites is shown in Figure 13, which is a schematic diagram of the puncture site in the prior art.

[0141] A second embodiment of the pressing component 3 is as follows: the pressing component 3 includes a pressing protrusion 3-1 and a positioning post 3-2, the pressing protrusion 3-1 being positioned by the positioning post 3-2.

[0142] It is fixed to the end of the inner side of the U-shaped pressing device 1. The pressing protrusion 3-1, the positioning post 3-2, and the upper clamping plate 1-2 are an integral fixed structure.

[0143] Since the upper clamping nut 4-4 and the lower clamping nut 4-5 need to exert force on each other to rotate to the appropriate position, after rotation, they clamp the lower clamping plate 1-3 relative to each other.

[0144] The diameter of the lower clamping nut 4-5 is set to be larger than the diameter of the upper clamping nut 4-4. The lower clamping nut 4-5, located slightly below the center, is conveniently positioned as the final clamping nut.

[0145] The lever nut is easier to operate than the upper clamping nut 4-4 when rotating. The lower clamping nut 4-5, with its larger diameter, is easier to grip with fingers, facilitating the movement of the lever nut.

[0146] Its force exerted causes the clamping force of both the upper clamping nut 4-4 to reach its maximum.

[0147] The scenario upon which this application is based is as follows: During radial artery 5 puncture, the patient needs to clench their fist, palm facing upwards, because...

[0148] The radial artery 5 has different locations and orientations in the forearm among different patients, therefore the cross-section of the forearm being clamped during hemostasis will also differ among different patients.

[0149] If the lower support structure of the forearm is in a fixed position, it is easy for the puncture point on the upper side of the forearm to deviate significantly from the center of the lower support structure.

[0150] The phenomenon of the forearm centerline causes instability during compression. Therefore, an adjustable support plate with adjustable curvature 4-1 needs to be designed to support the radial artery.

[0151] 5. The pressure point at the puncture site and the optimal indentation point of the adjustable support plate 4-1 should be as close as possible to each other on a straight line, while ensuring that the pressure direction deviates little from the puncture direction. The patient's forearm should rest precisely within the arc formed by the adjustable support plate 4-1, with the lower support point located precisely within the adjustable support plate 4-1.

[0152] The optimal concave point of the formed arc surface is used to ensure that the pressure points on both the upper and lower sides are aligned as much as possible in a straight line.

[0153] The curvature of the lower arm at the clamping surface is also related to the individual's weight and whether the individual is an adult. Therefore, the adjustable tray 4-1 can be adjusted.

[0154] After adjusting the inner curvature adjustment component, the middle curvature adjustment component, and the outer curvature adjustment component, the lower support arc with different matching degrees can be changed.

[0155] In addition, the adjustable pressing angle and direction of the upper pressing protrusion 3-1 are used to simulate the final position of the radial artery 5 puncture based on the patient's estimated position.

[0156] Securely clamp the forearm from above and below, ensuring it doesn't slip out of the clamping area during movement, before proceeding with the puncture. After the puncture, quickly apply gauze...

[0157] Press the cloth against the bleeding point, and replace the pressing finger with the pressing protrusion 3-1. At this time, straighten the device and tighten the adjusting nut 2-1 to make the U-shaped...

[0158] The elastic element 1-1 provides appropriate clamping force, reducing the manpower and time required by caregivers. It can be adjusted according to the patient's discomfort during subsequent compression phases.

[0159] Feedback indicates that caregivers can calibrate the compression process to prevent a sudden drop in clamping force.

[0160] The above description is merely a preferred embodiment of this utility model. It should be noted that, for those skilled in the art, without departing from the preferred embodiment, the following will be readily apparent.

[0161] Without deviating from the principle of this utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered within the scope of protection of this utility model.
