Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a distal radial artery compression hemostat. Background Art

[0002] In recent years, with the emergence of small-sized and thin-walled sheaths, people have begun to explore the puncture route of distal blood vessels. Domestic and foreign scholars have confirmed that the distal radial artery approach through the anatomical position of the snuffbox or Hegu acupoint is also safe and effective, and the patient is more comfortable during the operation. The distal radial artery is superficial and has more surrounding bony structures, which is conducive to puncture point positioning and postoperative compression hemostasis. It has become a hot spot for neurointerventional puncture approaches. The postoperative compression time and complication rate are significantly reduced, and it also adds an arterial approach option for patients undergoing coronary angiography and percutaneous coronary artery treatment.

[0003] More and more coronary artery diagnosis and treatment centers use the distal radial artery access during coronary angiography and percutaneous coronary therapy, while some domestic hospitals choose the distal radial artery access as the preferred approach for coronary angiography and percutaneous coronary therapy.

[0004] At present, the following methods are mainly used for compression hemostasis in China:

[0005] (1) Using elastic or sticky bandages to compress and stop bleeding, however, the bandage wrapping method requires folding a bandage in half several times, placing it on the puncture point, and then fixing it with the bandage. After the bandage is folded in half, the thickness increases. Although it can increase the pressure on the puncture point, the bandage is not hard enough, the pressure cannot be concentrated, and it needs to be wrapped multiple times. The method is cumbersome and the pressure on the puncture point cannot be adjusted again after completion.

[0006] (2) Use the Terumo radial artery hemostat without the plastic plate for compression hemostasis, or use a foreign distal radial artery hemostat for compression hemostasis. Although the above hemostasis methods are relatively simple to operate, due to the different original intentions of the radial artery hemostat in the initial design, its structure cannot fit well with the external tissue of the human body at the distal radial artery. The product has poor fixation and is not ergonomic. The reliability of the airbag structure is lower than that of the mechanical compression structure. Secondly, the product cannot directly check the pressure of the hemostat on the puncture point during the compression process. It only depends on the doctor's previous experience and cannot directly judge the degree of wound healing, which is easy to cause misjudgment and the wound is not closed.

[0007] Therefore, the current domestic hemostasis of the distal radial artery has shortcomings such as complex operation, inconvenient observation, and cumbersome use. Based on this, it is necessary to design a hemostat that can compress the puncture point of the distal radial artery, facilitate observation, and intuitively check the pressure value.

[0029] The utility model aims to provide a distal radial artery compression hemostat to solve the problems existing in the prior art, achieve compression hemostasis at the distal radial artery puncture point, facilitate observation, and intuitively check the pressure value.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1-Figure 5As shown, the utility model provides a distal radial artery compression hemostat, comprising a force-applying element, a force-transmitting element, a mounting element, a contact element and a connecting wristband 5, wherein the connecting wristband 5 is mounted on the mounting element, and the connecting wristband 5 is used to be put on the patient's hand and fix the mounting element on the patient's palm, thereby realizing the fixation of the contact element and the compression and hemostasis of the puncture point through the mounting element, the force-applying element is mounted on the end surface of the mounting element away from the patient's palm, so that medical staff can operate the force-applying element conveniently, the upper end of the force-transmitting element is mounted in the force-applying element, the lower end of the force-transmitting element passes through the mounting element and is connected to the contact element, the contact element is used to contact and compress the puncture point on the patient's palm, and then by operating the force-applying element, the force-transmitting element is driven to move, thereby realizing the movement of the contact element in a direction close to or away from the force-applying element, and finally realizing the adjustment of the contact pressure between the contact element and the patient's palm, the outer wall of the force-applying element is transparent and provided with scale lines, the scale lines are used to observe the position of the contact element, and then by observing the position of the scale lines aligned with the contact element, the contact pressure can be intuitively observed, and it is convenient to use.

[0032] Specifically, the mounting element is the main board 2, which is triangular in shape. Three mounting holes are arranged on the outer periphery of the main board 2, and the serial connecting lines between the three mounting holes form an isosceles triangle. The outer edge of the main board 2 corresponds to the positions on both sides of the vertex angle of the isosceles triangle, and both are concave arcs, and the central angle corresponding to the concave arc is 10° to 15°. The overall design is more adapted to the bone structure at the snuff box, and the concave arc design of the edge can effectively avoid the discomfort caused by stress concentration when the main board 2 contacts the human body.

[0033] Each mounting hole is provided with a connecting buckle 4, and each connecting buckle 4 is used to connect the end of the connecting wristband 5 to achieve a stable connection between the connecting wristband 5 and the mainboard 2. The above design enables the mainboard 2 to be more closely attached to the palm, making it more convenient to use.

[0034] The connecting wristband 5 includes a main wristband and an auxiliary wristband. The two ends of the main wristband are respectively connected to the connecting buckles 4 at the two bottom corners of the corresponding isosceles triangle, and the main wristband is used to be horizontally wrapped around the patient's palm to firmly fix the main board 2. One end of the auxiliary wristband is fixed to the middle of the main wristband by Velcro, and the other end is connected to the connecting buckle 4 at the top corner of the corresponding isosceles triangle, and the auxiliary wristband is applied to the depth of the palm where the patient's thumb and four fingers are separated.

[0035] The force-applying element is a knob 1, which is rotatably mounted on the mounting element, and an inner rod 6 is fixedly provided on the inner top surface of the knob 1. When the knob 1 is rotated, the inner rod 6 can be driven to rotate synchronously. The outer periphery of the inner rod 6 is cooperatively connected with the force-transmitting element, and the movement of the force-transmitting element can be realized through the rotation of the inner rod 6. The inner rod 6 is also made of transparent material.

[0036] The outer wall of the knob 1 is provided with a mark indicating the rotation direction, which can give the user a better warning during use and reduce the trial and error cost caused by incorrect rotation direction. As a preferred solution, the mark indicating the rotation direction is located on the upper end surface of the knob 1, which is clear and intuitive.

[0037] The force transmission element includes a spring 7 and a lock sleeve 8. The spring 7 is sleeved on the outer periphery of the inner rod 6, and the upper end of the spring 7 is installed on the limiting protrusion at the upper end of the outer wall of the inner rod 6. The lock sleeve 8 is sleeved on the outer periphery of the inner rod 6, and the lower end of the spring 7 is installed on the upper end of the lock sleeve 8. The lock sleeve 8 is provided with an external thread, and the upper end of the inner wall of the contact element is provided with an internal thread. The lock sleeve 8 is threadedly connected with the contact element, and the contact element is limited at the middle through hole of the main board 2, and can only move up and down but cannot rotate. When the knob 1 is turned, the knob 1 drives the inner rod 6 to rotate, the inner rod 6 drives the spring 7 to rotate, and the spring 7 drives the lock sleeve 8 to rotate. When the lock sleeve 8 rotates, it drives the contact element to move downward and increases the pressure between the contact element and the puncture point of the patient's palm. At the same time, the patient's palm gives the contact element an upward reaction force, so that the contact element drives the lock sleeve 8 to move upward again and compresses the spring 7.

[0038] The contact element includes a stud 9 and a silicone pad 3. A receiving groove is provided at the upper end of the stud 9. The upper end of the stud 9 extends into the knob 1, and the inner wall of the receiving groove is threadedly connected to the outer wall of the locking sleeve 8. A clamping ring is provided on the outer periphery of the lower end of the stud 9, and a clamping groove is provided at the upper end of the silicone pad 3. The clamping ring can be inserted into the clamping groove to realize the connection between the stud 9 and the silicone pad 3, and then the pressure between the silicone pad 3 and the puncture point on the palm of the patient is adjusted by raising and lowering the stud 9.

[0039] The stud 9 is made of non-transparent material and is combined with a knob 1 with a high-transparency design and scale lines, so that the height of the internal stud 9 can be clearly observed through the knob 1, and the corresponding pressure value on the knob 1 can be read according to the height of the stud 9. The bright color contrast makes it easy to observe during use. The height of the stud 9 corresponds to the pressure value, which is more intuitive and vivid.

[0040] The silicone pad 3 is made of highly transparent silicone to ensure transparency. During use, the real-time recovery of the wound can be clearly observed from the top, and the colored design of the stud 9 can form a sharp contrast with the blood color at the wound on both sides of the silicone pad 3, reducing the difficulty of observation. The Shore hardness of the silicone pad 3 is 40 to 50 degrees, and it is softer and more comfortable when fitting the human body.

[0041] The connection method between the various components of this embodiment and the pressure value display are all achieved by a simple mechanical matching structure. The clever gap design makes the rotation smoother without sticking or jerking, and can effectively ensure the pressure value display within the service life with high reliability.

[0042] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
