Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a trauma hemostatic device for emergency department. BACKGROUND

[0002] Femoral artery puncture is often used in emergency for rapid blood sampling or monitoring arterial blood pressure in emergency, and effective compression hemostasis should be performed on the puncture site after femoral artery puncture is completed to prevent complications such as hematoma and pseudoaneurysm. The femoral artery compression hemostat widely used in clinical practice at present is mostly based on mechanical pressure principle, which applies vertical pressure to the puncture site through rigid or semi-rigid compression plate combined with a bandage to prevent bleeding at the puncture site in the moment when the sheath is pulled out.

[0003] The compression hemostat currently used in the process usually needs to pull out the sheath a distance outward in advance, then install the hemostat on the patient's thigh, and make the hemostat apply extrusion force to the puncture site of the patient, and then remove the remaining sheath from the artery, but this will cause the muscle tissue near the puncture point to deform under pressure when the hemostat extrudes the puncture site, and the deformed muscle tissue will extrude the sheath in the blood vessel, increasing the resistance of the remaining sheath when being pulled out, causing the puncture catheter to drag the puncture site in a frictional manner, causing secondary injury to the wound of the puncture site.

Detailed Implementation

[0040] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] Example 1: A wound hemostasis device for use in the emergency department, such as... Figures 1-3 As shown, it includes: a bracket 1, with a support member 2 fixedly connected to one side of the bracket 1, a fixing member 3 provided in the middle of the bracket 1, and a storage cavity 4 provided on the other side of the bracket 1; a first threaded rod 5, threadedly connected to the side of the bracket 1 away from the support member 2; a connecting rod 6, rotatably connected to the first threaded rod 5, the connecting rod 6 passing through the bracket 1 and slidably connected to it; a first pressing block 7, rotatably connected to the lower side of the connecting rod 6, the first pressing block 7 being provided with a groove for assisting the removal of the puncture device; a connecting plate 8, fixedly connected to the upper part of the connecting rod 6, the connecting plate 8 sliding within the storage cavity 4; and an adjusting component, provided on the side of the connecting plate 8 away from the connecting rod 6, the adjusting component being used to change the tilt angle of the first pressing block 7 during the process of changing the position of the first pressing block 7.

[0042] In the above scheme, the support 2 and the fixing 3 are existing devices. The fixing 3 is used to fix the bracket 1 to the patient's leg, and the support 2 is used to provide a fulcrum for the first compression block 7. In this article, the installation process of the support 2 and the fixing 3 will not be described in detail. In this article, the support 2 is located on the right side of the bracket 1. When this device is used, the proximal end of the femoral artery is located on the left side of the device, and the distal end is located on the right side. The storage cavity 4 is located on the left side of the bracket 1. The first threaded rod 5 is located on the left side of the storage cavity 4. The first threaded rod 5 and the connecting rod 6 are used together to change the height of the left side of the first compression block 7 to compress the patient's femoral artery. A removable compression pad is installed on the lower side of the first compression block 7 (the compression pad is an existing device and is not shown in the figure).

[0043] like Figure 3 and Figure 4As shown, the adjusting assembly comprises a second threaded rod 9 threadedly connected to the connecting plate 8 at a side away from the connecting rod 6, the second threaded rod 9 penetrating through the bracket 1; a transmission rod 91 rotatably connected to a lower side of the second threaded rod 9; and a connecting seat 10 rotatably connected to the transmission rod 91, the connecting seat 10 being in limit sliding connection with the first extrusion block 7.

[0044] In the above scheme, the second threaded rod 9 is located at the right side of the connecting plate 8; the connecting seat 10 can only move leftward and rightward along the first extrusion block 7; and the second threaded rod 9, the transmission rod 91 and the connecting seat 10 are collectively used to change the height of the right side of the first extrusion block 7.

[0045] As shown in Figure 3 , the maximum distance of the movement of the connecting plate 8 on the bracket 1 is A, the length of the part of the second threaded rod 9 located outside the bracket 1 is B, A is not greater than B, so that when the connecting plate 8 drives the second threaded rod 9 to move downward to the limit position, the upper side of the second threaded rod 9 is still partly located outside the storage cavity 4, facilitating the rotation of the second threaded rod 9 by the staff.

[0046] As shown in Figure 3 and Figure 4 , when the first extrusion block 7 is in the horizontal position, the minimum distance between the central axis of the first threaded rod 5 and the center point of the first extrusion block 7 is equal to the minimum distance between the central axis of the second threaded rod 9 and the center point of the first extrusion block 7, so that the first extrusion block 7 can provide more uniform extrusion force to the patient's muscle.

[0047] The specific working process of the above scheme is as follows:

[0048] When it is needed to use the device to compress and stop bleeding at the femoral artery puncture site of a patient, the staff first pulls out the sheath pipe by a distance, then fixes the bracket 1 on the patient's thigh through the support 2 and the fixing member 3, then rotates the first threaded rod 5 to drive the connecting rod 6 to move downward, and drives the first extrusion block 7 and the connecting plate 8 to move downward synchronously (in this process, the connecting plate 8 drives the second threaded rod 9 to move downward synchronously, the second threaded rod 9 drives the connecting seat 10 to move downward through the transmission rod 91, thereby driving the right side of the first extrusion block 7 to move downward synchronously), when the first extrusion block 7 moves downward to contact the skin on the side close to the heart end of the patient's puncture site, the staff stops rotating the first threaded rod 5 and rotates the second threaded rod 9 to drive the connecting seat 10 to move upward through the transmission rod 91, i.e., to drive the right side of the first extrusion block 7 to move upward.

[0049] In the process of upward movement of the connecting seat 10, the right side of the first extrusion block 7 is synchronously moved upward by the connecting seat 10, so that the first extrusion block 7 rotates around the connection between the first extrusion block 7 and the connecting rod 6, thereby changing the inclination angle of the first extrusion block 7. Meanwhile, in the process of transition of the first extrusion block 7 from the horizontal state to the inclined state, the first extrusion block 7 drives the connecting seat 10 to synchronously rotate relative to the transmission rod 91 (changing the included angle between the connecting seat 10 and the transmission rod 91), and the connecting seat 10 is moved rightward relative to the first extrusion block 7 under the extrusion of the first extrusion block 7. After the rotation angle of the first extrusion block 7 is adjusted to be appropriate, the worker stops rotating the second threaded rod 9, and continues to rotate the first threaded rod 5, so that the first threaded rod 5 drives the first extrusion block 7 in the inclined state to continue to move downward through the connecting rod 6 (in this process, the connecting rod 6 drives the second threaded rod 9 to move downward through the connecting plate 8, so as to synchronously move the right side of the first extrusion block 7 downward), so that the left side of the first extrusion block 7 mainly presses the left side (the side close to the heart end) of the puncture site of the patient, reduces the pressure in the femoral artery blood vessel close to the heart end of the patient, and simultaneously reduces the extrusion force on the puncture point of the patient, thereby reducing the extrusion force of the muscle of the patient on the sheath, reducing the resistance of the sheath in the process of pulling out, and reducing the discomfort of the patient in the process of pulling out the sheath.

[0050] After the first extrusion block 7 moves downward by a distance (i.e., after the extrusion force of the first extrusion block 7 on the heart end of the artery of the patient can achieve the purpose of hemostasis), the worker continues to pull out the sheath outward, and continues to rotate the first threaded rod 5 in the process of pulling out, so as to gradually increase the pressing force of the first extrusion block 7 on the left side of the puncture site of the patient, thereby reducing the impact force of the blood flow in the femoral artery on the puncture point, and reducing the risk of jet hemorrhage when the wound is exposed.

[0051] After the sheath is completely pulled out, the first threaded rod 5 moves downward to a specified position, and then the worker stops rotating the first threaded rod 5 and synchronously rotates the second threaded rod 9, so that the second threaded rod 9 drives the right side of the first extrusion block 7 to move downward through the transmission rod 91 and the connecting seat 10 (in this process, the first extrusion block 7 gradually resets from the inclined state to the horizontal state, and drives the connecting seat 10 to slide and reset relative to the first extrusion block 7), so as to increase the extrusion force of the first extrusion block 7 on the right side of the puncture site of the patient, thereby providing uniform extrusion force of the first extrusion block 7 on the surrounding of the puncture site of the patient, so as to improve the compression effect on the puncture site of the patient. In the process of downward movement of the right side of the first extrusion block 7 driven by the second threaded rod 9, the worker can flexibly adjust the extrusion force of the right side of the first extrusion block 7 on the heart end of the puncture site of the patient through the rotation number of the second threaded rod 9. After the position of the right side of the first extrusion block 7 is adjusted, the worker stops rotating the second threaded rod 9.

[0052] In the process of using the device to compress the puncture site of the patient, the staff rotates the first threaded rod 5 and the second threaded rod 9 according to the nursing needs, thereby driving the first extrusion block 7 to move upward, reducing the extrusion force on the puncture site of the patient, until the puncture site of the patient no longer needs compression, the staff removes the device from the patient's thigh, rotates the first threaded rod 5 and the second threaded rod 9 to reset the first extrusion block 7 to the initial position, then disassembles the parts in the device that are in direct contact with the patient's skin, and separates the parts in direct contact with the patient's skin from the remaining parts for processing.

[0053] Example 2: Based on example 1, as shown in Figure 4 and Figure 5 , it also includes: two second extrusion blocks 11 are symmetrically distributed, and are both limitingly and slidingly connected to the first extrusion block 7; two telescopic rods 12 are symmetrically distributed, and are both slidingly connected to the connecting plate 8, the telescopic end of the telescopic rod 12 is rotationally connected with a moving seat 13, and the moving seat 13 is slidingly connected with the adjacent second extrusion block 11; two third threaded rods 14 are symmetrically distributed, and are both threadedly connected to the support 1, and the third threaded rod 14 is rotationally connected with the fixed part of the adjacent telescopic rod 12.

[0054] In the above scheme, the two second extrusion blocks 11 and the two telescopic rods 12 are symmetrically distributed; the lower side of each of the two second extrusion blocks 11 is provided with a detachable compression pad; the moving seat 13 slides left and right on the adjacent second extrusion block 11; at the initial time, the lower side of the second extrusion block 11 forms a complete arc surface with the lower side of the first extrusion block 7; the second extrusion block 11 can only move up and down along the first extrusion block 7.

[0055] As shown in Figures 4-6 , the first extrusion block 7 and the lower side of the two second extrusion blocks 11 are both provided with an arc surface, which is used to increase the contact area with the patient's skin when in contact with the patient's skin.

[0056] As shown in Figure 4 and Figure 5 , the fixed part of the telescopic rod 12 is threadedly connected with a fourth threaded rod 15, the fourth threaded rod 15 penetrates through the adjacent third threaded rod 14, and the fourth threaded rod 15 is used to limit the telescopic end of the adjacent telescopic rod 12 when the second extrusion block 11 is in contact with the patient.

[0057] In the above scheme, initially, the fourth threaded rod 15 is located at the uppermost side of the adjacent telescopic rod 12, and the fourth threaded rod 15 does not contact the telescopic end of the adjacent telescopic rod 12.

[0058] The specific working process of the above scheme is as follows:

[0059] In the process of the first pressing block 7 tilting, the first pressing block 7 drives the two second pressing blocks 11 to tilt synchronously, and in the process of the second pressing blocks 11 tilting, the second pressing blocks 11 drive the adjacent moving seats 13 to rotate along the joints between the moving seats 13 and the telescopic ends of the adjacent telescopic rods 12 (change the included angle between the horizontal planes of the moving seats 13), in this process, the moving seats 13 move rightward relative to the adjacent second pressing blocks 11, and at the same time, the two second pressing blocks 11 respectively extrude the telescopic ends of the adjacent telescopic rods 12 through the moving seats 13 on the second pressing blocks 11, so that the telescopic ends of the telescopic rods 12 move upward under the extrusion force.

[0060] In the process of the first pressing block 7 moving downward, the first pressing block 7 extrudes the muscles of the puncture part of the patient, and at the same time, the muscles of the puncture part of the patient react on the two second pressing blocks 11, so that the two second pressing blocks 11 move upward under the extrusion force, and in the process of the first pressing block 7 changing from the tilting state to the horizontal state, the first pressing block 7 drives the two second pressing blocks 11 to change to the horizontal state synchronously, and at the same time, the second pressing blocks 11 drive the adjacent moving seats 13 to reset to the non-rotated state, and make the second pressing blocks 11 be extruded by the muscles of the patient again in the process of resetting, so as to drive the telescopic ends of the adjacent telescopic rods 12 to move upward.

[0061] After the staff stops rotating the second threaded rod 9 for the second time (i.e. after the first pressing block 7 rotates to the horizontal state), the two second pressing blocks 11 move upward to the limit position under the extrusion of the muscles of the patient, and then the staff rotates the two fourth threaded rods 15, so that the two fourth threaded rods 15 respectively move downward along the fixed parts of the adjacent telescopic rods 12, and when the fourth threaded rods 15 move downward to contact the telescopic ends of the adjacent telescopic rods 12, the fourth threaded rods 15 continue to move downward to extrude the telescopic ends of the adjacent telescopic rods 12, so that the telescopic ends of the telescopic rods 12 drive the adjacent moving seats 13 and the adjacent second pressing blocks 11 to move downward synchronously, and the two second pressing blocks 11 press the muscles of the patient located in the first pressing block 7, so that the second pressing blocks 11 and the first pressing block 7 together provide uniform pressure on the muscles around the puncture part of the patient, and after the lower side of the second pressing blocks 11 and the lower side of the first pressing block 7 form a complete arc surface again (i.e. after the telescopic ends of the telescopic rods 12 move downward to the limit position), the staff stops rotating the two fourth threaded rods 15.

[0062] In the process of continuously pressing the muscles of the puncture part of the patient, when the patient feels uncomfortable at the pressing site, the staff can selectively move the first pressing block 7 upward (rotate the first threaded rod 5) or move the two second pressing blocks 11 upward (rotate the two third threaded rods 14), so that the first pressing block 7 and the two second pressing blocks 11 alternately press the puncture part of the patient, thereby reducing the time of a certain part being pressed when the puncture part of the patient is pressed, and reducing the discomfort of the patient due to long-term pressure.

[0063] When the puncture site of the patient no longer needs compression, the staff removes the device from the patient's thigh and maintains and cleans the device.

[0064] Example 3: Based on Example 2, as shown in Figure 4 and Figure 6 , further comprising a connecting block 17 fixed between the two second pressing blocks 11, the connecting block 17 is provided with a groove, the groove of the connecting block 17 is located in the middle of the lower side, and the staff can set a certain amount of hemostatic dressing in the groove of the connecting block 17 to increase the healing speed of the puncture of the patient.

[0065] As shown in Figure 6 , the lower side of the connecting block 17 is curved with the same curvature as the upper arc surface of the first pressing block 7, and the connecting block 17 is made of an elastic deformable material, so that the connecting block 17 can be deformed under the extrusion of the hemostatic dressing, thereby providing the hemostatic dressing with extrusion force, but the extrusion force should not be too large to increase the discomfort of the patient.

[0066] In the above scheme, considering that in the process of compression hemostasis of the puncture site of the patient, if the patient is a high-risk patient (such as a coagulation disorder), a certain amount of hemostatic dressing is also needed to assist the compression hemostat in the process of compression hemostasis of the patient, so as to speed up the healing speed of the puncture site of the patient, thereby shortening the required compression time, the specific operation is as follows:

[0067] Before pulling out the sheath, the staff first adjusts the position of the device, moves the connecting block 17 to the upper side of the puncture site, then fixes the device on the thigh of the patient according to the above operation, and covers a certain amount of hemostatic dressing on the puncture site of the patient, then the staff pulls out the sheath completely, adjusts the positions of the first pressing block 7 and the two second pressing blocks 11 according to the above operation, and presses the puncture site of the patient by the first pressing block 7 and the two second pressing blocks 11, in this process, the hemostatic dressing is located in the groove on the lower side of the connecting block 17, at the same time, the hemostatic dressing can react on the connecting block 17, so that the connecting block 17 is extruded by the hemostatic dressing and deformed upward, increasing the volume of the groove on the connecting block 17, thereby covering the hemostatic dressing in the groove of the connecting block 17 to maintain the stability of the position of the hemostatic dressing, thereby reducing the distance of the movement of the dressing caused by the movement of the patient's leg, and improving the utilization rate of the hemostatic dressing.

[0068] Example 4: Based on Example 3, as shown in Figure 3 , Figure 4 and Figure 6As shown, further comprises: two mounting blocks 18 symmetrically distributed, the mounting block 18 is slidably connected to the first extrusion block 7, the mounting block 18 and the first extrusion block 7 are fixedly connected with the spring 19, and the mounting block 18 is provided with a limiting groove; two limiting rods 20 symmetrically distributed, each is slidably connected to the first extrusion block 7, and the limiting rod 20 is slidably connected in the limiting groove of the adjacent mounting block 18.

[0069] In the above scheme, the two mounting blocks 18 are symmetrically distributed, and the lower side of the two mounting blocks 18 is provided with an elastic air bag (existing device, not shown in the figure), thereby increasing the shielding effect of the mounting block 18 on the adjacent groove of the first extrusion block 7; the spring 19 is in a compressed state at the beginning.

[0070] The specific working process of the above scheme is as follows:

[0071] After adjusting the position of the first extrusion block 7, the worker pulls the two limiting rods 20 forward, so that the limiting rod 20 loses contact with the adjacent mounting block 18, then the mounting block 18 moves downward under the action of the adjacent spring 19, and the elastic air bag on the mounting block 18 moves downward synchronously, so that the elastic air bag contacts the skin of the patient, thereby shielding the adjacent groove of the first extrusion block 7 by the elastic air bag, reducing the proportion of pollutants in the external environment into the patient's puncture site, thereby reducing the area of the patient's puncture site contacting the external environment, and reducing the risk of infection of the patient's puncture site.

[0072] After the device is used, the worker dismounts the device from the patient's thigh, and resets the two mounting blocks 18 and the two limiting rods 20 to the initial position, so that the two springs 19 are in a compressed and stored state again, ready for subsequent use.

[0073] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
