Description

Technical Field

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

[0002] Interventional therapy is a minimally invasive treatment performed using modern high-tech means - that is, under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body to diagnose and locally treat pathologies in the body. Commonly used interventional therapy techniques are divided into intravascular intervention and non-intravascular intervention. The commonly used surface puncture points for intravascular interventional surgery include the femoral artery and vein, radial artery, subclavian artery and vein, jugular artery and vein, brachial artery, etc. The brachial artery is located on the inner side of the middle section of the upper arm, very deep, and after the interventional surgery is completed, the puncture site needs to be compressed by a compression device to stop bleeding.

[0003] The existing compression hemostasis device usually uses a fixing belt to restrain the patient's upper arm during use, so that the puncture site is compressed and hemostatic through an adjustable compression plate. However, the fixing belt makes the patient's skin feel uncomfortable after restraining the upper arm for a long time, and the adjustment part of the compression hemostasis device is usually exposed to the outside without protection. The brachial artery is located in the middle of the upper arm. During the compression hemostasis process, the compression hemostasis device can easily contact the side of the patient's body close to the puncture site, thereby contacting the adjustment part of the compression hemostasis device, causing the position of the compression plate to change, resulting in poor compression effect and blood seepage. Therefore, a brachial artery compression hemostasis device is proposed to solve the above problems. Utility Model Content

It solves the problem that the existing compression hemostat usually uses a fixation belt to restrain the patient's upper arm position during use, so as to compress and stop bleeding at the puncture position through the adjustable compression plate, but the fixation belt makes the patient's skin feel uncomfortable after restraining the upper arm for a long time, and the adjustment part of the compression hemostat is usually exposed to the outside without protection, and the brachial artery is located in the middle of the upper arm. During the compression hemostasis process, the compression hemostat can easily come into contact with the side of the patient's body close to the puncture position, thereby coming into contact with the adjustment part of the compression hemostat, causing the position of the compression plate to change, resulting in poor compression effect and blood seepage.

The left and right sides of the support pad 2 are connected to the left and right sides of the mounting plate 1 by a connecting belt 3. The interior of the mounting plate 1 is connected with a threaded rod 4 through a threaded transmission. A compression plate 5 is fixedly installed at the bottom of the threaded rod 4. A knob 6 is fixedly installed at the top of the threaded rod 4. A mounting groove 7 is provided on the top of the mounting plate 1. A cover plate 8 movably connected to the inside of the mounting groove 7 is movably installed on the top of the mounting plate 1. Limiting grooves 9 symmetrically distributed frontward and backward are provided on the left and right sides of the cover plate 8. Four positioning grooves 10 distributed in a rectangular shape are provided inside the mounting plate 1. A limiting mechanism 11 is arranged inside the positioning groove 10. The limiting mechanism 11 is clamped with the cover plate 8, and the top of the knob 6 fits with the bottom of the inner wall of the cover plate 8.

[0029] The surface of the cover plate 8 is coated with a rubber coating to reduce discomfort when in contact with the patient's limbs, and a label can also be attached to the surface of the cover plate 8 to record and observe the time of compression and hemostasis at the patient's puncture site.

[0030] As a preferred embodiment of the present invention, the limiting mechanism 11 includes a spring 1101, a moving block 1102, a limiting block 1103 and a pushing rod 1104. The spring 1101 is fixedly connected to one end of the positioning slot 10 away from the cover plate 8, the other end of the spring 1101 is fixedly connected to one end of the moving block 1102 away from the cover plate 8, the moving block 1102 is slidably connected to the inside of the positioning slot 10, the end of the moving block 1102 close to the cover plate 8 is fixedly connected to the end of the limiting block 1103 away from the cover plate 8, the limiting block 1103 is slidably connected to the inside of the limiting slot 9, the top of the moving block 1102 is fixedly connected to the bottom of the pushing rod 1104, and the pushing rod 1104 extends to the top of the mounting plate 1.

[0031] The push rod 1104 can drive the moving block 1102 to move, so that the limiting block 1103 is removed from the limiting groove 9 , and the cover plate 8 can be taken out from the mounting plate 1 .

[0032] As a preferred embodiment of the present invention, a telescopic rod 12 is fixedly mounted on the bottom of the inner wall of the cover plate 8 and extends to the inside of the mounting plate 1 , and a sleeve 13 located outside the threaded rod 4 is fixedly mounted on the top of the mounting plate 1 .

[0033] The knob 6 is restricted so that the position of the compression plate 5 will not change during the process of compressing and stopping bleeding.

[0034] As a preferred embodiment of the present invention, connecting blocks 14 with a hollow interior are fixedly mounted on the left and right sides of the mounting plate 1 , and the connecting belt 3 passes through the connecting block 14 and is bonded to the supporting pad 2 .

[0035] As a preferred embodiment of this embodiment, the support pad 2 includes a skin-friendly layer 201 , a breathable layer 202 , and a wear-resistant layer 203 .

[0037] When the support pad 2 contacts the patient's upper arm, the patient's experience is better, and the support pad 2 is breathable and wear-resistant, thus extending the service life.

[0038] As a preference of this embodiment, there are several limiting grooves 9 which are evenly distributed on the outer side of the cover plate 8 .

[0039] According to the moving distance of the threaded rod 4 , the position of the limiting groove 9 can also be adjusted to better protect the knob 6 .

[0040] Working principle:

[0041] When in use, the support pad 2 is first brought into contact with the patient's upper arm, so that the connection belt 3 passes through the connection block 14 to connect the mounting plate 1, and can be bonded to the outer side of the support pad 2 to complete the initial fixation, and then the knob 6 is rotated to move the threaded rod 4 to drive the compression plate 5 to compress the puncture site. At the same time, under the action of the connection belts 3 on both sides, a supporting effect is formed, so that the compression plate 5 is more stable during the working process;

[0042] Then, pull the push rod 1104 outward to install the cover 8, and the telescopic rod 12 passes through the knob 6 and enters the interior of the mounting plate 1, thereby restricting the knob 6. Release the push rod 1104, and push the moving block 1102 to move under the action of the spring 1101, so that the limiting block 1103 enters the interior of the limiting groove 9, thereby restricting the cover 8 and ensuring that it is more stable during subsequent use.
