Description

Technical Field

[0001] The present application relates to a radial artery compressor, which is mainly used for compressing the radial artery after radial artery-related surgery to prevent postoperative bleeding. Background Art

[0002] Cardiac intervention is a novel diagnostic and treatment technique for cardiovascular disease. It involves puncturing a superficial blood vessel to establish a channel. Using continuous digital subtraction angiography, a cardiac catheter is inserted through the channel. Using specialized catheterization techniques, the diagnosis and treatment of heart disease are confirmed. Currently, it is a relatively advanced and rapidly evolving approach to heart disease diagnosis and treatment, situated between medical and surgical treatments. It includes procedures such as coronary angiography, PTCA with stenting, interventional treatment for congenital heart disease, and intracoronary thrombolysis. Postoperatively, the radial artery puncture site requires decremental pressure to stop bleeding, requiring pressure for at least 30 minutes. Currently, radial artery compression hemostat devices are primarily available in balloon, spiral, and direct compression types. Currently, commonly used radial artery compression hemostats are single-use devices. Compression hemostasis is often performed blindly, with no intuitive or quantitative understanding of compression intensity. Pressure can only be estimated based on the physician's experience. Excessive pressure can cause limb ischemia and even cardiac arrest in patients with severe heart disease due to a cardiovagal reflex. Excessive pressure can cause hematoma at the puncture site, resulting in poor hemostasis and inability to achieve precise compression hemostasis. Furthermore, clinical staff have no reliable basis for recording initial and adjusted compression intensity and duration.

[0003] See patent publication number CN 211156035 U, titled "A Radial Artery Compressor for Instantly Absorbing Bleeding." The patented radial artery compressor can quickly absorb bleeding, allowing doctors to observe bleeding and provide appropriate treatment. However, the patented design has two drawbacks: 1. It cannot roughly determine the pressure range, requiring time to adjust; 2. When the radial artery compressor is removed after surgery, the pressure can easily fluctuate significantly, leading to bleeding.

[0004] CN 207855744 U discloses a radial artery compression hemostat capable of digitally displaying compression pressure, which has a complex structure and high cost, thus increasing the financial burden on patients and is rarely used in clinical work. Summary of the Invention

[0005] The technical problem solved by the present application is to overcome the above-mentioned deficiencies in the prior art and to provide a radial artery compressor that can roughly judge the pressure and record it, is safe after surgery, and is not prone to bleeding.

[0006] The technical solution adopted by the present application to solve the above-mentioned technical problems is: a radial artery compressor, comprising a mounting plate, a wristband, a pressure plate device, and a pressure-applying device. A pressure-applying device is provided on the front side of the mounting plate, and the pressure-applying device is connected to the pressure plate device provided on the rear side of the mounting plate. The invention is characterized in that a pressure marker is also provided, and the wristband has an elastic structure that can be stretched along the extension direction of the wristband. The pressure marker includes a pressure marker strip that is elastic and will not stretch. The pressure marker strip is installed on the mounting plate or on the wristband and extends along the outside of the wristband. The plane where the center line of the pressure marker strip is located is parallel to the upper and lower side planes of the wristband. A pressure marker scale is provided on the pressure marker strip, and the pressure marker scale corresponds to the degree of stretching of the wristband. The approximate range of compression of the patient's radial artery is indicated by the amount of stretching deformation of the wristband. On the one hand, it is convenient for doctors to quickly adjust the appropriate approximate range of compression of the patient's radial artery based on the relationship between the pressure marker and the amount of stretching of the wristband. On the other hand, the elastic structure of the wristband also helps to prevent the pressure from dropping to zero immediately when the radial artery compressor is released after the operation is completed, thereby preventing the pressure from dropping too quickly.

[0007] The inner side of the wristband in contact with the operator's arm is a smooth surface, which helps to improve measurement accuracy.

[0008] The pressure marker is installed on one side of the mounting plate, one end of the pressure marker strip is installed on the pressure marker mounting portion, the pressure marker strip is in an arc-shaped needle shape, and the other end of the pressure marker strip extends to the other side of the mounting plate.

[0009] The pressure marker consists of a pressure marking strip and an elastic band. The wristband consists of a fixed part at one end of the wristband, a middle part of the wristband, and a fixed part at the other end of the wristband. The middle part of the wristband is made of stretchable elastic material, and the fixed part at one end of the wristband, the middle part of the wristband, and the fixed part at the other end of the wristband are made of non-stretchable material. An initial position marking line is provided on the middle part of the wristband. One end of the pressure marking strip is fixed to the fixed part at one end of the wristband, and the other end of the pressure marking strip is connected to one end of the elastic band. The other end of the elastic band is fixed to the fixed part at the other end of the wristband or the wristband mounting part. The other end of the pressure marking strip is pulled by the elastic band to ensure that the pressure marking strip fits well with the outside of the wristband, making it convenient for the doctor to observe the position of the initial position marking line on the pressure marking strip.

[0010] The pressure marking scale includes pressure marking scale zero, a first pressure marking scale, a second pressure marking scale ... an i-th pressure marking scale, where i is a positive integer, and the pressure differences between adjacent gears (i.e., between pressure marking scale zero and the first pressure marking scale, between the first pressure marking scale and the second pressure marking scale, between the second pressure marking scale and the third pressure marking scale ...) are the same.

[0011] When the wristband is unstretched, the initial position indicator line corresponds to the zero pressure mark on the pressure indicator. When the wristband is stretched to the first level, the initial position indicator line corresponds to the first pressure mark on the pressure indicator. When the wristband is stretched to the second level, the initial position indicator line corresponds to the second pressure mark on the pressure indicator. When the wristband is stretched to the i-th level, the initial position indicator line corresponds to the i-th pressure mark on the pressure indicator. The pressure differences between adjacent levels are the same. Therefore, medical personnel can roughly determine the radial artery compression device's approximate pressure based on the position of the initial position indicator line on the installed radial artery compression device. If the pressure value is not appropriate, they can adjust the pressure applying device to move the pressure plate assembly back and forth to achieve a roughly appropriate pressure. The radial artery compression device does not require extremely precise pressure measurement on the patient's radial artery. The level design can be designed to have an error within one level based on the required accuracy. Since the visual error is usually less than half a level, the wristband pressure error only needs to be controlled to no more than half a level. The specific number of levels and the pressure level within each level can be determined based on actual needs. As a special example, i=4, with a pressure difference of 30 mmHg between each level.

[0012] The two ends of the wristband are respectively fixed to the pressure mark mounting part and the wristband mounting part of the mounting plate through Velcro.

[0013] Compared with the existing technology, the present application has the following advantages and effects: simple structure, easy to use, can quickly and roughly judge the pressure size, improves operating efficiency, and is not prone to bleeding after surgery.

DETAILED DESCRIPTION

[0018] The present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are intended to explain the present application but the present application is not limited to the following examples. Figure 1 The upper left center is the front, and the lower right center is the back.

[0019] See also Figure 1 、 Figure 2 The radial artery compressor of the present application embodiment comprises a mounting plate 1, a wristband 2, a pressure plate device 3, and a pressure device 4. The wristband 2 is mounted on both sides of the mounting plate 1. The pressure device 4 is provided on the front side of the mounting plate 1. The pressure device 4 is connected to the pressure plate device 3 provided on the rear side of the mounting plate 1. The structural feature of the present application is that a pressure marker 5 is further provided. The wristband 2 has a pressure mark extending along the wristband ( Figure 1 The pressure marker 51 is an elastic structure that is stretched in the direction of extension of the pressure marker 5. The pressure marker 5 indicates the approximate range of compression of the patient's radial artery through the amount of compression and stretching of the wristband 2. On the one hand, it is convenient for the doctor to quickly adjust the appropriate approximate range of compression of the patient's radial artery based on the relationship between the pressure marker 5 and the stretching deformation of the wristband 2. On the other hand, the elastic structure of the wristband 2 also helps to prevent the pressure from dropping to zero immediately when the radial artery compressor is released after the operation is completed, thereby preventing the pressure from dropping too quickly.

[0020] One way to install the pressure marker 5 is to install it on a certain side of the mounting plate 1. The pressure marker 5 includes a pressure marker strip 51 that is elastic and will not stretch. One end of the pressure marker strip 51 is installed on the pressure marker mounting portion 11 and is located outside the contact surface between the wristband 2 and the pressure marker. The pressure marker strip 51 has an arc-shaped needle-like structure. The other end of the pressure marker strip 51 extends to the right side of the mounting plate 1 and roughly fits the outside of the wristband 2. The plane where the center line of the pressure marker strip 51 is located is parallel to the upper and lower side planes of the wristband 2 (the wristband width is the same, so the upper side plane of the wristband is parallel to the lower side plane), ensuring that the extension direction of the pressure marker strip 51 is consistent with the extension direction of the wristband 2. Figure 1 As shown; Another installation method of the pressure marker 5 is to install it directly on the wristband 2. In this case, the wristband 2 can be composed of two parts, for example, the part close to the wristband fixing column 112 is made of non-stretchable material, and the rest is made of stretchable material; or three parts, the two ends of the wristband (the fixing portion 21 at one end of the wristband and the fixing portion 23 at the other end of the wristband) are made of non-stretchable material, and the middle part 22 of the wristband is made of stretchable material, see Figure 3 Because the travel of the pressure-applying device 4 cannot be too long, the stretchable portion of the wristband 2 should be minimal. Only the middle portion of the wristband 2 is stretchable, which helps reduce the movement of the pressure plate 3 caused by changes in the wristband's length. Furthermore, the inner side of the wristband 2, which contacts the operator's arm, is smooth, which helps improve measurement accuracy.

[0021] As a special case, the wristband 2 adopts a three-part structure connected in sequence, see Figure 3The wristband's fixed portion 21 at one end and the wristband's fixed portion 23 at the other end are made of a non-stretchable material, while the wristband's middle portion 22 is made of a stretchable elastic material. An initial position identification line 221 is provided on the wristband's middle portion 22. The pressure marker 5 comprises a pressure identification strip 51 and an elastic band 52. One end of the pressure identification strip 51 is fixed to the wristband's fixed portion 21 at one end, while the other end is connected to one end of the elastic band 52. The other end of the elastic band 52 is fixed to the wristband's fixed portion 23 at the other end (or the wristband mounting portion 12). The elastic band 52 holds the other end of the pressure identification strip 51, ensuring that the pressure identification strip 51 is in contact with the back of the wristband 2, making it easier for the doctor to observe the position of the initial position identification line 221 on the pressure identification strip 51. When the wristband 2 is not stretched, the initial position marking line 221 corresponds to the pressure marking scale zero 510 on the pressure marker 5. When the wristband 2 is stretched to the first level, the initial position marking line 221 corresponds to the first pressure marking scale 511 on the pressure marker 5. When the wristband 2 is stretched to the second level, the initial position marking line 221 corresponds to the second pressure marking scale 512 on the pressure marker 5... When the wristband 2 is stretched to the i-th level, the initial position marking line 221 corresponds to the i-th pressure marking scale 51i on the pressure marker 5, where i is a positive integer. Therefore, medical personnel can roughly judge the approximate data of the radial artery compressor based on the position of the initial position marking line 221 on the installed radial artery compressor. When the pressure value is not appropriate, the pressure plate device 3 can be moved back and forth by adjusting the pressure-applying device 4 until the pressure is approximately appropriate. The radial artery compressor does not need to be particularly precise in the pressure on the patient's radial artery. The gear design can be designed to have an error within 1 gear according to the accuracy requirements. Since visual error is typically less than half a level, it's sufficient to control wristband 2's pressure error to no more than half a level (total error ≤ visual error + wristband pressure error). For example, if a patient's appropriate radial artery pressure is 1.75, the physician can simply fine-tune the pressure-applying device 4 so that the initial position marker 221 is approximately 3 / 4 of the way between the first and second levels. The specific number of levels and the pressure level within each level can be designed based on actual needs; typically, five levels (i=4) are used, with each level having a specific pressure of 30 mmHg.

[0022] The pressure plate assembly 3 and pressure-applying assembly 4 described herein can both utilize existing technology. Specific data for the radial artery compressor can be obtained through experimentation. For example, a hand model with a sensor can be designed and installed within the radial artery compressor. The sensor is aligned with the pressure plate assembly 3 and connected to a computer. The material and length of the wristband 2, as well as the pressure-applying assembly 4, can be adjusted so that the initial position marking line 221 corresponds to the pressure marking scale zero 510 when the wristband 2 is unstretched, the initial position marking line 221 corresponds to the first pressure marking scale 511 when the wristband 2 is stretched to the first pressure level, and the second pressure marking scale 512 when the wristband 2 is stretched to the second pressure level. [The following sentences appear unrelated and should likely be omitted.]

[0023] The two ends of the wristband 2 can also be fixed to the pressure indicator mounting portion 11 and the wristband mounting portion 12 of the mounting plate 1, respectively. The fixing method can adopt existing technologies, such as Velcro fixing or wrapping and perforating fixing similar to the elastic band of swimming goggles. For example, a Velcro side 61 is provided on the back of one end of the wristband 2, and the other end of the wristband 2 is fixedly sleeved on the wristband mounting portion 12. The wristband fixing column 112 is provided with a Velcro side 62. After the one end of the wristband 2 passes through the wristband perforation 111, the Velcro side 61 and the Velcro side 62 are affixed and fixed.

[0024] In specific applications, the appropriate radial artery compressor can be selected based on the patient's specific circumstances. After the procedure is completed, the puncture site is bandaged, and the radial artery compressor is installed and secured with the pressure plate aligned with the puncture site. Pressure is applied by the pressure-applying device 4 until the radial artery pressure exceeds the systolic pressure (generally, slightly above the systolic pressure is sufficient to minimize compression side effects and prevent bleeding at the puncture site). The time and pressure marker position (the position of the initial position marker line 221 relative to the pressure marker 5) are recorded. The compression pressure is then reduced over time, and the time and pressure marker position are recorded. When the compression pressure approaches zero and no new bleeding or hematoma has occurred, the compressor can be removed.

[0025] The wristband structure of the present application can be used as the elastic band part of a radial artery compression hemostat, such as an airbag compression type, a spiral compression type, or a direct compression type.
