Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a hemostatic compression device for cardiology. Background Technology

[0002] Cardiology commonly uses hemostatic compression devices primarily for hemostasis at the puncture site after interventional procedures via the radial or femoral artery. The core objectives are rapid hemostasis, reduction of complications (such as radial artery occlusion RAO), and improvement of patient comfort.

[0003] Current hemostatic compression devices mainly consist of two parts: a Velcro strap and the compression device itself. When in use, the Velcro strap is used to fix the device to the patient's puncture site, and then the compression device is used to apply pressure to stop the bleeding. This fixation method results in high local pressure on the patient's limb, and the patient is not comfortable with prolonged compression. Moreover, the compression device is not stable and has low positioning efficiency when fixed with only Velcro strap. Therefore, this invention provides a hemostatic compression device for cardiology to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hemostatic compression device for cardiology. By setting a first positioning rod and a second positioning rod at both ends of the support rod, the stability of the overall structure of the compression device can be greatly improved. Compared with the prior art, it not only improves the comfort of the patient's limb, but also further ensures the positioning efficiency of medical staff for the compression device. The above settings can solve the problems of poor stability and low positioning efficiency of the current compression device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A cardiology hemostatic compression device includes a support rod with a first positioning rod and a second positioning rod fixedly connected to its two ends. A strap mounting plate is symmetrically installed on both sides of the middle position of the support rod, and a Velcro strap is installed on the strap mounting plate. A second limiting plate is installed at the bottom of the Velcro strap. A compression component is also included, used to assist medical personnel in applying pressure to the patient's puncture site for hemostasis. The compression component is connected to both the first and second positioning rods.

[0006] Optionally, the compression assembly includes a first limiting plate rotatably connected to the bottom of the first positioning rod, and the compression assembly also includes a rectangular rod slidably connected to the second positioning rod and a pressing rod inserted into the second positioning rod, with a pressing plate fixedly connected to the bottom of the pressing rod.

[0007] Optionally, a second connecting block is fixedly connected to the top of the first limiting plate, and a first connecting block is fixedly connected to the bottom of the first positioning rod. The first connecting block and the second connecting block are connected together by bolts and nuts for limited rotation. The first positioning rod and the first limiting plate are connected by the first connecting block and the second connecting block.

[0008] Optionally, the bottom of the second positioning rod is provided with a slot corresponding to the position of the rectangular rod. There are four rectangular rods in total, and the four rectangular rods are distributed on the four sides of the second positioning rod. A pressing rod is fixedly connected to the bottom of the rectangular rod. The connection position between the rectangular rod and the pressing rod is an outwardly flipped arc-shaped profile. A roller is rotatably connected to the outer wall of the pressing rod. The roller is made of metal.

[0009] Optionally, a limiting cylinder is fixedly connected to the top of the rectangular rod, a first insert is inserted into the limiting cylinder, a second insert is fixedly connected to the end of the first insert away from the limiting cylinder, and a push plate is fixedly connected to the end of the second insert away from the first insert.

[0010] Optionally, there is a gap between the first insert block and the inner wall of the limiting cylinder. A spring is fixedly connected to one end of the first insert block near the limiting cylinder. The spring is located in the gap between the first insert block and the limiting cylinder. One end of the spring is fixed to the first insert block and the other end is fixed to the inner wall of the limiting cylinder. The size of the first insert block is larger than the size of the second insert block.

[0011] Optionally, the second positioning rod is provided with an adjustment groove, which is composed of a large round hole and a small round hole. A plurality of the large round holes and the small round holes are arranged in a linear array to form the adjustment groove, wherein the size of the large round hole matches the size of the first insert block, and the size of the small round hole matches the size of the second insert block.

[0012] Optionally, the second positioning rod is provided with a placement groove, in which a first clamping plate and a second clamping plate are inserted and fixed. An adjusting ball is rotatably connected between the first clamping plate and the second clamping plate, and the pressing rod is screwed into the adjusting ball.

[0013] Optionally, the inner wall of the first clamping plate is in contact with the outer wall of the adjusting ball, a locking pad is slidably connected inside the second clamping plate, the inner wall of the locking pad is in contact with the outer wall of the adjusting ball, the locking pad is made of rubber, a second adjusting knob is rotatably connected to the outer wall of the locking pad, the second adjusting knob is screwed to the second positioning rod, and a first adjusting knob is fixedly connected to the top of the pressing rod.

[0014] Optionally, a conical insert is fixedly connected to the outer wall of both the first clamping plate and the second clamping plate. The conical insert consists of a straight rod and a conical head. The second positioning rod has a groove that matches the size of the straight rod. The conical head has a conical structure and its size is larger than that of the straight rod.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a compression component, the first limiting plate, in conjunction with the second limiting plate, can support and limit the limb at the top and bottom of the patient's puncture point. Compared with existing technologies, this setting not only improves the comfort of the patient's limb but also further ensures the positioning efficiency of the compressor by medical personnel and improves the stability of the compressor. By setting a squeezing rod on the second positioning rod, when using this compressor, the squeezing rod is first used to stretch and compress the skin near the patient's puncture point, allowing the skin near the puncture point to be fully stretched, so that medical personnel can easily observe the puncture point. This improves the compression effect while enhancing the positioning of the puncture point by medical personnel. By setting a roller on the squeezing rod, not only can the patient's discomfort when the squeezing rod squeezes the patient's skin be reduced and the squeezing rod be prevented from excessively pulling the patient's skin and causing discomfort, but also the low temperature of the roller's metal material can be used to apply ice to the patient's skin surface, thereby reducing the patient's discomfort during the process of the squeezing rod pulling the patient's skin and improving the hemostatic effect of the compressor.

[0016] Furthermore, by setting an adjustable ball, medical staff can rotate the pressure rod to change the angle of the pressure plate, thereby making the pressure plate more accurately press against the patient's puncture point, improving the efficiency and accuracy of the pressure device's positioning. Medical staff can also rotate the pressure rod to move the pressure plate toward the patient's skin surface, thereby achieving the effect of pressure hemostasis at the puncture point. Combined with the traction effect of the squeezing rod on the patient's skin, the efficiency of pressure plate positioning and pressure hemostasis can be further improved.

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0022] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0023] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0024] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0025] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0026] like Figures 1 to 3As shown, an embodiment of the present invention provides a cardiology hemostatic compression device, including a support rod 1. A first positioning rod 2 and a second positioning rod 9 are fixedly connected to both ends of the support rod 1, respectively. A strap mounting plate 6 is symmetrically installed on both sides of the middle position of the support rod 1. A Velcro strap 7 is installed on the strap mounting plate 6, and a second limiting plate 8 is installed at the bottom of the Velcro strap 7. In this technical solution, by setting the first positioning rod 2 and the second positioning rod 9 at both ends of the support rod 1, the stability of the overall structure of the compression device can be greatly improved. Compared with the prior art, it not only improves the comfort of the patient's limb, but also further ensures the positioning efficiency of the compression device by medical personnel.

[0027] As one implementation method in this embodiment, such as Figures 1 to 4 As shown, the compression assembly is used to assist medical personnel in applying pressure to the puncture site of the patient to stop bleeding. The compression assembly is connected to the first positioning rod 2 and the second positioning rod 9 respectively. The compression assembly includes a first limiting plate 4 rotatably connected to the bottom of the first positioning rod 2. A second connecting block 5 is fixedly connected to the top of the first limiting plate 4. A first connecting block 3 is fixedly connected to the bottom of the first positioning rod 2. The first connecting block 3 and the second connecting block 5 are rotatably connected together by bolts and nuts. The first positioning rod 2 and the first limiting plate 4 are connected by the first connecting block 3 and the second connecting block 5.

[0028] Since the first connecting block 3 and the second connecting block 5 are connected together by bolts and nuts for limited rotation, the first limiting plate 4 and the first positioning rod 2 can rotate and adjust their angles relative to each other. This allows the first limiting plate 4 to provide well-adapted support and limitation for the contour of the patient's limb. The first limiting plate 4, together with the second limiting plate 8, can support and limit the limb at the top and bottom of the patient's puncture point. This design improves the stability of the compressor while enhancing the patient's limb comfort.

[0029] In this embodiment, as Figures 5 to 8As shown, the compression assembly also includes a rectangular rod 11 slidably connected to the second positioning rod 9 and a pressing rod 17 inserted into the second positioning rod 9. The bottom of the second positioning rod 9 has a slot 10 corresponding to the position of the rectangular rod 11. There are four rectangular rods 11 in total, distributed along the four sides of the second positioning rod 9. The bottom of the rectangular rod 11 is fixedly connected to the pressing rod 17. The connection point between the rectangular rod 11 and the pressing rod 17 is an outwardly folded arc shape. A roller 18, made of metal, is rotatably connected to the outer wall of the pressing rod 17. Because the rectangular rod 11 and... The connection point of the compression rod 17 has an outward-curving arc shape. Therefore, when medical personnel slide the compression rod 17 downward to compress the patient's skin, the compression rod 17 will bend outward along the patient's skin surface. This bending effect of the compression rod 17 stretches and compresses the patient's skin. This design allows the compression device to first stretch and compress the skin near the puncture point with the compression rod 17, making the skin near the puncture point fully stretched. This makes it easier for medical personnel to observe the puncture point, improving the compression effect while enhancing the ability of medical personnel to locate the puncture point.

[0030] Furthermore, by rotating a roller 18 on the outer wall of the compression rod 17, the roller 18 rotates along the compression rod 17 when the compression rod 17 presses against the patient's skin. This arrangement not only reduces the patient's discomfort when the compression rod 17 presses against the patient's skin and prevents the compression rod 17 from excessively pulling on the patient's skin, but also, since the roller 18 is made of metal, the low temperature of the metal material allows the roller 18 to apply an ice pack to the patient's skin surface. This arrangement can reduce the patient's discomfort during the process of the compression rod 17 pulling on the patient's skin.

[0031] Optionally, the compressor provided in this application can be placed in a low-temperature storage box during routine storage to improve the cooling effect of the roller 18 on the patient's skin surface.

[0032] In this embodiment, as Figures 5 to 10As shown, a limiting cylinder 12 is fixedly connected to the top of the rectangular rod 11. A first insert 13 is inserted into the limiting cylinder 12. A second insert 15 is fixedly connected to the end of the first insert 13 away from the limiting cylinder 12. A push plate 16 is fixedly connected to the end of the second insert 15 away from the first insert 13. There is a gap between the first insert 13 and the inner wall of the limiting cylinder 12. A spring 14 is fixedly connected to the end of the first insert 13 near the limiting cylinder 12. The spring 14 is located in the gap between the first insert 13 and the limiting cylinder 12. Within the gap, one end of the spring 14 is fixed to the first insert 13 and the other end is fixed to the inner wall of the limiting cylinder 12. The size of the first insert 13 is larger than the size of the second insert 15. An adjustment groove 19 is provided on the second positioning rod 9. The adjustment groove 19 is composed of two parts: a large round hole and a small round hole. Several large round holes and small round holes are arranged in a linear array to form the adjustment groove 19. The size of the large round hole matches the size of the first insert 13, and the size of the small round hole matches the size of the second insert 15.

[0033] To facilitate medical staff in adjusting the pressure of the compression rod 17 on the patient's skin, a first insert 13 and a second insert 15 are provided on the rectangular rod 11, working in conjunction with an adjustment groove 19 to assist medical staff in adjusting the height of the compression rod 17. Specifically, under the elastic force of the spring 14, the first insert 13 is inserted into the large circular hole in the adjustment groove 19. When the height of the compression rod 17 needs to be adjusted, the medical staff first presses the push plate 16. During the pressing process, the first insert 13 moves towards the inner wall of the limiting cylinder 12, while the spring 14 deforms and contracts under force. When the first insert 13 is completely disengaged from the adjustment groove 19, the second insert 15 is located within the adjustment groove 19. Since the size of the second insert 15 is smaller than that of the first insert 13, the adjustment groove 19 cannot effectively limit the second insert 15. At this point, the medical staff can slide the push plate 16 to adjust the height of the compression rod 17. During the sliding of the push plate 16, the second insert 15 slides within the adjustment groove 19. The size of the small round hole on the groove 19 matches the size of the second insert 15. Therefore, the second insert 15 will not be blocked by the adjustment groove 19 during the sliding process. When the height of the compression rod 17 is appropriate, the medical staff stops pressing the push plate 16. Under the elastic force of the spring 14, the first insert 13 automatically resets and re-locks into the large round hole on the adjustment groove 19. The small round hole on the adjustment groove 19 blocks and limits the first insert 13, thereby achieving the fixing effect of the compression rod 17. The above structure can improve the efficiency of medical staff in adjusting the height of the compression rod 17. Moreover, the structure is simple and easy to operate. It is worth mentioning that the four rectangular rods 11 are distributed on the four sides of the second positioning rod 9. Therefore, medical staff can adjust the height of the four compression rods 17 to pull the patient's skin in all directions, so that the skin near the puncture point is fully pulled open, allowing the puncture point to be fully exposed, improving the efficiency and effect of subsequent compression positioning.

[0034] In this embodiment, as Figures 4 to 6 and Figures 11 to 13 As shown, a pressure plate 26 is fixedly connected to the bottom of the pressure rod 24. A placement groove 20 is provided on the second positioning rod 9, and a first clamping plate 21 and a second clamping plate 22 are inserted and fixed in the placement groove 20. Conical inserts 29 are fixedly connected to the outer walls of the first clamping plate 21 and the second clamping plate 22. The conical insert 29 consists of a straight rod and a conical head. A groove adapted to the size of the straight rod is provided on the second positioning rod 9. The conical head has a conical structure and its size is larger than that of the straight rod. An adjusting ball 23 is rotatably connected between the first clamping plate 21 and the second clamping plate 22. The pressure rod 24 is screwed into the adjusting ball 23. The inner wall of the first clamping plate 21 fits against the outer wall of the adjusting ball 23. A locking pad 27 is slidably connected inside the plate 22. The inner wall of the locking pad 27 fits against the outer wall of the adjusting ball 23. The locking pad 27 is made of rubber. A second adjusting knob 28 is rotatably connected to the outer wall of the locking pad 27. The second adjusting knob 28 is screwed to the second positioning rod 9. A first adjusting knob 25 is fixedly connected to the top of the pressure rod 24. The first clamping plate 21 and the second clamping plate 22 are both fixed in the placement groove 20 by the conical insert 29. Since the conical head has a conical structure and the size of the conical head is larger than the size of the straight rod, the size difference between the conical head and the straight rod can be used to achieve the fixing effect of the first clamping plate 21 and the second clamping plate 22. This fixing method is simple in structure and convenient to operate.

[0035] Furthermore, grooves adapted to the size of the adjusting ball 23 are formed on the inner walls of both the first clamping plate 21 and the second clamping plate 22. Therefore, the adjusting ball 23 can be enclosed and limited by the first clamping plate 21 and the second clamping plate 22, preventing misalignment and detachment during rotation. In addition, circular clearance grooves (such as...) are formed at both ends of the first clamping plate 21 and the second clamping plate 22. Figure 13 As shown, the clearance groove is designed to ensure that the compression rod 24 is not blocked or limited by the first clamping plate 21 and the second clamping plate 22 when it rotates. Since the compression rod 24 is screwed and fixed in the adjusting ball 23, medical personnel can rotate the compression rod 24 to change the angle of the compression plate 26, so that the compression plate 26 can more accurately press against the patient's puncture point, improving the efficiency and accuracy of the compression positioning. When the medical personnel rotate the compression rod 24, the compression plate 26 moves toward the patient's skin surface under the action of the thread drive, thereby achieving the effect of compression hemostasis at the puncture point. The above-mentioned positioning operation of the puncture point and the operation of compression hemostasis at the puncture point are simple. Combined with the pulling effect of the compression rod 17 on the patient's skin mentioned above, the positioning and compression hemostasis efficiency of the compression plate 26 can be further improved.

[0036] Furthermore, by setting a locking pad 27 on the inner wall of the second clamping plate 22, the adjusting ball 23 can be locked and fixed. Since the second adjusting knob 28 is screwed and fixed to the second positioning rod 9, when the medical staff rotates the second adjusting knob 28, the locking pad 27 will move toward the position of the adjusting ball 23 and squeeze the adjusting ball 23 under the action of the thread. Since the locking pad 27 is made of rubber, its surface friction is large, so the effect of squeezing and fixing the adjusting ball 23 can be achieved.

[0037] The working principle of the technical solution provided by this invention is as follows: In use, medical staff place the second positioning rod 9 directly above the puncture point according to the location of the puncture point on the patient's limb, and then use the Velcro strap 7 to fix the support rod 1 to the patient's limb. After the support rod 1 is fixed, the first limiting plate 4 and the second limiting plate 8 are located on the limb at the top and bottom of the puncture point of the patient, respectively, which can wrap and limit the patient's limb and improve stability.

[0038] After the support rod 1 is fixed, the medical staff presses the push plates 16 on both sides of the second positioning rod 9 simultaneously with their index finger and thumb. During the pressing process, the first insertion block 13 moves toward the inner wall of the limiting cylinder 12. At the same time, the spring 14 deforms and contracts under force. When the first insertion block 13 is completely disengaged from the adjusting groove 19, the second insertion block 15 is located in the adjusting groove 19. Since the size of the second insertion block 15 is smaller than that of the first insertion block 13, the adjusting groove 19 cannot block and limit the second insertion block 15. At this time, the medical staff can slide the push plate 16 to adjust the height of the squeezing rod 17, so that the squeezing rod 17 squeezes the patient's puncture point. When the squeezing rod 17 comes into contact with the patient's skin, it bends outward along the skin surface, thus stretching and squeezing the skin near the puncture point to facilitate observation of the puncture point by medical personnel. Once the squeezing rod 17 is at the appropriate height, the medical personnel stop pressing the push plate 16. Under the elastic force of the spring 14, the first insert 13 automatically resets and re-locks into the large round hole on the adjusting groove 19. The small round hole on the adjusting groove 19 then limits and separates the first insert 13, thereby fixing the squeezing rod 17.

[0039] After the skin near the patient's puncture point is stretched, the medical staff rotates the compression rod 24 to change the angle of the compression plate 26, so that the compression plate 26 can be pressed more accurately at the patient's puncture point. When the compression plate 26 is aligned with the patient's puncture point, the medical staff rotates the compression rod 24, and the compression plate 26 moves toward the patient's skin surface under the action of the thread, thereby achieving the effect of compression hemostasis at the puncture point.

[0041] The above description is only a preferred embodiment of the present invention.
