Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical care, and more specifically, the present invention is a nursing component after cardiac intervention. Background Art
[0002] Cardiac intervention is a new type of technology for diagnosing and treating cardiovascular diseases. Without thoracotomy, under the guidance of imaging methods, through puncturing the surface blood vessels of the body, with the help of special instruments, the catheter is sent to the lesion site, and the heart disease is diagnosed and treated through specific cardiac catheter operation techniques. It is a relatively advanced method for diagnosing and treating heart diseases, and the progress is also very rapid. It is between medical treatment and surgical treatment and is an invasive diagnosis and treatment method. Among them, in the nursing after cardiac intervention, in order to prevent infection at the puncture site, medical dressings are usually used to compress, relieve pain and prevent infection at this site. In nursing, the dressings at the puncture site should be kept clean and dry, closely monitor the body temperature changes and whether there are redness, abnormal secretions and general conditions at the wound, etc., and strictly implement aseptic technique operations.
[0003] During the use of current medical dressings, medical tapes or straps are usually used to wrap and bind around the puncture site, and the dressing is pressed and fixed to the puncture site from top to bottom. Since the fixing direction of the dressing is relatively single, and the volume of the dressing pack is usually much larger than the area of the puncture site (in order to achieve the purposes of compression, infection prevention, etc., the volume of the dressing pack is usually relatively large), therefore, during use, with the patient's turning over, getting up and lying down and other movements, the dressing pack is prone to lateral displacement from the fixed part, resulting in the failure of compression. On the other hand, during the process of replacing the dressing pack, it is necessary to loosen the medical tape or strap to relieve the continuous compression of the dressing pack on the puncture site, and perform the steps of re-dressing and applying medicine. During this period, there is a certain gap in the compression effect on the puncture site, so that after the compression on the puncture site is removed, the pressure at the puncture site will change greatly in a short time. Improper operation will lead to complications such as congestion and hematoma at the puncture site of the puncture site, and the safety of the dressing use needs to be improved. Summary of the Invention
[0004] To overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a nursing component after cardiac intervention. By setting a fixed base, an arc-shaped elastic bracket, a pressing block, an arc surface A and an arc surface B, and through the mutual cooperation of them, when ensuring that the pressing block gradually presses the gauze pack in a vertical posture from top to bottom, the arc surfaces A and B at both ends of the pressing block will take the midline of the pressing seam as the base point and displace and deform horizontally towards the left and right sides along the Y-shaped form of the pressing seam. Thus, while the pressing block presses and fixes the gauze pack from top to bottom as a whole, the upper part of the gauze pack is pressed in two horizontally opposite directions by the arc surfaces A and B on both sides of it, so as to form a multi-dimensional pressing direction inside the gauze pack to solve the problems proposed in the above-mentioned background technology.
[0005] To achieve the above object, the present invention provides the following technical solution: A nursing component after cardiac intervention, including a base, a pair of fixed straps are fixedly inlaid on the side of the fixed base, a conical accommodating groove is opened inside the fixed base, an inclined surface is connected and arranged at the bottom end of the conical accommodating groove, a dressing port is opened at the bottom end of the fixed base and is connected to the inclined surface, and the side of the inclined surface close to the dressing port gradually ends with an arc track; On both sides of the inner wall of the conical accommodating groove, a pair of arc-shaped elastic brackets are symmetrically inlaid. On one side of the head end of each of the pair of arc-shaped elastic brackets, a limiting plate is integrally formed. A hook head is fixedly installed at one end of the limiting plate. The arc-shaped elastic bracket as a whole is in an arc-shaped bending structure, and the arc-shaped concave part thereof points to the upper oblique direction of the top end of the fixed base. The ends of the arc-shaped elastic bracket and the limiting plate are both designed with rounded corners. The limiting plate and the hook head as a whole form an L-shaped structure, and the included angle at the connection between the limiting plate and the hook head < 90°. The hook head as a whole is in an arc-shaped line, and the arc-shaped concave part of the hook head points to one side direction of the limiting plate; A pressing block is fixedly installed on the bottom surface of the arc-shaped elastic bracket and on the side of the limiting plate. On the left and right sides of the bottom end of the pressing block, an arc surface A and an arc surface B are respectively integrally formed. A pressing seam is formed at the connection between the arc surface A and the arc surface B. The shape of the side of the pressing block close to the arc-shaped elastic bracket is adapted to the outer shape of the arc-shaped elastic bracket. The overall track length of the arc surface A is greater than the track length of the arc surface B. The overall track of the arc surface A gradually distributes in a parabolic shape from the root side to the side close to the pressing seam and closes in a rounded corner shape at the joint with the pressing seam. The arc surface B as a whole is in a spherical convex shape. The pressing seam as a whole is distributed in a Y-shaped form, and one end of the pressing seam extends into the pressing block and is greater than half of the overall thickness of the pressing block. When the arc-shaped elastic bracket is bent to the working posture, the lowest points of the arc postures of the arc surface A and the arc surface B are located on the same horizontal line.
[0006] In a preferred embodiment, the arc-shaped elastic bracket, the limiting plate, and the hook head are all made of elastic materials, and the pair of limiting plates are kept on the same horizontal line as a whole.
[0007] In a preferred embodiment, the included angle between the inclined surface and the bottom end of the conical accommodating groove is > 90°, the distance between the pair of hook heads is greater than the deformation allowance of the arc-shaped elastic bracket as a whole, and the pair of limiting plates are rotationally symmetrically arranged at 180°.
[0008] In a preferred embodiment, the extrusion block, the arc surface A, and the arc surface B are all made of elastic rubber materials.
[0009] In a preferred embodiment, the surfaces of the arc surface A and the arc surface B are provided in a matte shape as a whole.
[0010] In a preferred embodiment, the pair of limiting plates can be detachably adapted and fixed to each other through the hook heads that are rotationally symmetrically arranged at their own ends.
[0011] Technical effects and advantages of the present invention: By providing a fixed base, an arc-shaped elastic bracket, an extrusion block, an arc surface A, and an arc surface B, and using the cooperation of several of them, during the process of ensuring that the extrusion block gradually presses the gauze pack in a vertical posture from top to bottom, the arc surfaces A and B at both ends of the extrusion block will take the midline of the extrusion seam as the base point and displace and deform horizontally toward the left and right sides along the Y-shaped form of the extrusion seam. Thus, while the extrusion block presses and fixes the gauze pack from top to bottom as a whole, the arc surfaces A and B at both ends of it respectively press the upper part of the gauze pack in two horizontally opposite directions, so as to form a multi-dimensional pressing direction inside the gauze pack, preventing the dressing pack from laterally shifting from the fixed part with the patient's actions such as turning over and getting up and lying down after fixation, resulting in problems such as compression failure; At the same time, during the replacement of the gauze pack, the fixed base can be continuously used to compress and stop bleeding the periphery of the puncture site through the binding band, so that the compression pre-tightening force on the puncture site always exists, directly avoiding the problem of compression voids in the compression effect on the puncture site during dressing change, and greatly reducing the postoperative adverse conditions such as congestion and hematoma at the puncture site of the puncture site.

Detailed implementation manners
[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0015] As shown in the attached Figure 1 to the attached Figure 16A cardiac intervention postoperative care component shown in the figure includes a fixed base 1. A pair of fixed straps 2 are fixedly inlaid on the side of the fixed base 1. A conical accommodation groove 3 is opened inside the fixed base 1. The bottom end of the conical accommodation groove 3 is communicated with an inclined surface 4. A dressing port 5 is opened at the bottom end of the fixed base 1 and communicated with the inclined surface 4. The side of the inclined surface 4 close to the dressing port 5 gradually ends with an arc-shaped track. With the above settings, it is ensured that when the inclined surface 4 supports the gauze pack, there is no right-angle contact dead angle between it and the gauze pack, thus avoiding the dead angle of fitting and insufficient contact between the two, effectively improving the lifting and placing effect of the gauze pack, and ensuring that the overall compression fitting shape between the gauze pack and the puncture site is good when the gauze pack is in a fixed state; On both sides of the inner wall of the conical accommodation groove 3, a pair of arc-shaped elastic brackets 61 are symmetrically inlaid. On one side of the head ends of the pair of arc-shaped elastic brackets 61, a limiting plate 62 is integrally formed. A hook head 63 is fixedly installed at one end of the limiting plate 62. The arc-shaped elastic bracket 61 is integrally in an arc-shaped bending structure, and the arc-shaped depression of this points to the upper oblique direction of the top end of the fixed base 1. The ends of the arc-shaped elastic bracket 61 and the limiting plate 62 are both designed with rounded corners. The limiting plate 62 and the hook head 63 integrally form an L-shaped structure, and the included angle at the connection between the limiting plate 62 and the hook head 63 < 90°. The hook head 63 is integrally in an arc-shaped line, and the arc-shaped depression of the hook head 63 points to one side direction of the limiting plate 62. With the above settings, it can be ensured that during the relative sliding and fixing process of the pair of arc-shaped elastic brackets 61 and the limiting plate 62, the smoothness is relatively high, and problems such as mutual jamming are not likely to occur, further increasing the practicality of the device; On the bottom surface of the arc-shaped elastic support 61 and on one side of the limiting plate 62, an extrusion block 71 is fixedly installed. On the left and right sides of the bottom end of the extrusion block 71, an arc surface A72 and an arc surface B73 are integrally formed respectively. An extrusion seam 74 is formed at the connection of the arc surface A72 and the arc surface B73. The shape of the side of the extrusion block 71 close to the arc-shaped elastic support 61 is adapted to the outer shape of the arc-shaped elastic support 61. The overall track length of the arc surface A72 is greater than the track length of the arc surface B73. The arc surface A72 is gradually distributed in a parabolic shape as a whole from the root side to the side close to the extrusion seam 74, and is closed in a rounded corner form at the joint with the extrusion seam 74. The arc surface B73 is in a spherical convex shape as a whole. The extrusion seam 74 is distributed in a Y-shaped form as a whole, and one end of the extrusion seam 74 extends into the interior of the extrusion block 71 and is greater than half of the overall thickness of the extrusion block 71. When the arc-shaped elastic support 61 is bent to the working posture, the lowest points of the arc postures of the arc surface A72 and the arc surface B73 are located above the same horizontal line. With the above settings, it is ensured that during the process of the extrusion block 71 gradually pressing on the gauze pack, the arc surfaces A72 and B73 at both ends of the extrusion block 71 will take the midline of the extrusion seam 74 as the base point and perform lateral displacement deformation along the Y-shaped form of the extrusion seam 74 towards its left and right sides. Thus, while the extrusion block 71 presses on the gauze pack from top to bottom as a whole, the upper part of the gauze pack is pressed in two horizontally opposite directions by the arc surfaces A72 and B73 at both ends respectively, so as to complete the locking of the gauze pack in multiple directions, preventing the dressing pack from laterally shifting with the patient's turning over, getting up and lying down and other movements after being fixed, resulting in problems such as compression failure, and further improving its safety.
[0016] The arc-shaped elastic support 61, the limiting plate 62 and the hook head 63 are all made of elastic materials as a whole. The pair of limiting plates 62 are kept on the same horizontal line as a whole. The distance range between the pair of hook heads 63 is greater than the deformation allowance of the arc-shaped elastic support 61 as a whole. With the above settings, the two hook heads 63 can be clamped and fixed to each other before the arc-shaped elastic support 61 reaches the maximum deformation amount. The pair of limiting plates 62 are rotationally symmetrically arranged at 180°. The extrusion block 71, the arc surface A72 and the arc surface B73 are made of elastic rubber materials as a whole. With the above settings, the deformation degrees of the extrusion block 71, the arc surface A72 and the arc surface B73 are high, so that they can better make deformation contact with the top of the gauze pack, and thus perform pressing operations in multiple dimensional directions, further improving the use effect of the device.
[0017] For specific reference, see the attached Figure 3 - attached Figure 5, the overall surfaces of the arc surface A72 and the arc surface B73 are provided with a matte finish, and the included angle between the inclined surface 4 and the bottom end of the conical accommodating groove 3 > 90°.
[0018] The specific implementation method is as follows: By setting the included angle between the inclined surface 4 and the conical accommodating groove 3, during the process of placing the gauze pack, it can ensure that the gauze pack is placed in the conical accommodating groove 3 in a natural hanging state, which is convenient for subsequent fixing operations of the gauze pack and further increases its practicality.
[0019] Specifically refer to the attached Figure 10 , a pair of the limiting plates 62 can be detachably and adaptively fixed to each other through the hook heads 63 that are rotationally symmetrically arranged at their own ends.
[0020] The specific implementation method is as follows: The pair of hook heads 63 are hooked and fixed to each other, and the limiting plates 62 and the hook heads 63 as a whole form an L-shaped structure, enabling the pair of hook heads 63 to be adaptively hooked and tightened, and at the same time, they can slide and shift to unhook, which is convenient for the operator to flexibly fix and release them.
[0021] The working principle of the present invention: The first step: First, the operator normally assembles each component of the device, and then uses the device normally.
[0022] Step 2: First, the operator places the gauze pack inside the conical receiving groove 3, ensuring that the gauze pack is located above the inclined surface 4. Then, the operator presses and fixes the fixed base 1 to the upper part of the patient's puncture site through the fixing strap 2. At the same time, ensure that the dressing port 5 at the bottom end of the fixed base 1 is directly above the puncture position. At this time, the fixing process of the fixed base 1 is completed. Subsequently, the operator pinches a pair of arc-shaped elastic brackets 61 respectively and applies pressure to deform them towards one side of the conical receiving groove 3, making the whole gradually approach the top surface of the gauze pack. Finally, the ends of the pair of arc-shaped elastic brackets 61 are hooked and fixed together through the sliding fit of the two groups of hook heads 63 and the limiting plate 62. At this time, when the arc-shaped elastic brackets 61 are released, the detachable fixing operation of the arc-shaped elastic brackets 61 can be completed through the two groups of hook heads 63. At the same time, the extrusion block 71 contacts and presses the upper part of the gauze pack as a whole. During the process that the extrusion block 71 gradually contacts the top side of the gauze pack and applies pressure to it step by step, the arc-shaped surfaces A72 and B73 at both ends of the extrusion block 71 will take the midline of the extrusion seam 74 as the base point and displace horizontally to the left and right sides along the Y-shaped extrusion seam 74. Thus, while the extrusion block 71 presses the gauze pack from top to bottom as a whole, the upper part of the gauze pack is pressed in two horizontally opposite directions by the arc-shaped surfaces A72 and B73 at both ends respectively. Therefore, a multi-dimensional pressure application direction is formed inside the whole gauze pack, ensuring that while the gauze pack is vertically fixed, there is also a pre-tightening force horizontally. Further ensure that after the gauze pack undergoes flexible deformation, it fully contacts and presses against the upper part of the puncture site. Since the gauze pack is composed of external gauze and multiple internal dressings, it has good deformation ability as a whole. When the gauze pack needs to be replaced after it is fixed, the operator only needs to continue to twist the two limiting plates 62 as a whole, making the hook heads 63 slide and shift relatively, so that they become loose from each other. Then the old gauze pack can be directly taken out and a new gauze pack can be replaced. And during the replacement process, the whole fixed base 1 can continuously press and stop bleeding the periphery of the puncture site, ensuring that the pressing pre-tightening force on the puncture site always exists, directly avoiding the problem of the pressing effect on the puncture site having a gap during dressing change, and greatly reducing the probability of problems such as congestion and hematoma at the puncture site of the puncture part. Finally, the device completes the working process of dressing and nursing the puncture site, and that's it.
[0023] Step 3: First, the operator normally shuts down the device. Then, the operator checks whether the fixity between the various components of the device is normal. Then, the aging and severely worn parts inside the device are replaced and repaired.
