Description

Technical Field

[0001] The utility model relates to the technical field of hemostatic sleeves, in particular to a hemostatic sleeve capable of quickly adjusting binding pressure. Background Art

[0002] A tourniquet cuff is a medical device used to temporarily stop bleeding. It is usually made of elastic material and can be adjusted in size and pressure. It is usually applied to limbs such as arms or legs to restrict blood flow and reduce bleeding. Tourniquet cuffs are often used in emergency situations, such as trauma or accidental injuries, to delay or prevent consequences such as shock caused by more serious bleeding. Before using a tourniquet cuff, the injured area should be cleaned and emergency medical treatment should be sought.

[0003] In the process of stopping bleeding on the patient's arm, a hemostatic cuff is needed to stop bleeding on the wound on the patient's arm. In the existing operation method, medical staff mostly place the cuff on the arm and wrap it around it, and fix it with Velcro. This wrapping method has great force and can easily cause poor blood circulation. Therefore, medical staff need to adjust the tightness of the hemostatic cuff at corresponding intervals. When adjusting the tightness of the hemostatic cuff, the Velcro needs to be completely separated from the surface of the hemostatic cuff and then re-attached. This adjustment method has a large amplitude of movement and can easily cause discomfort to the patient, and it is inconvenient to quickly adjust the binding pressure.

[0004] Therefore, a hemostatic cuff capable of quickly adjusting the binding pressure is proposed to solve the above problems. Utility Model Content

A buffer pad 22 is fixedly installed on the back of the transmission box 5. By providing the buffer pad 22, the friction between the transmission box 5 and the patient's skin can be increased to prevent the staff from accidentally touching the transmission box 5 during the bandaging process of the patient, causing the transmission box 5 to drive the hemostatic cuff body 1 to shake and cause secondary damage to the patient's wound. The interior of the transmission box 5 is fixedly connected to a gear rod 6 through a bearing seat;

[0035] Reference Figure 1-3The top of the gear rod 6 passes through the top of the transmission box 5. A ratchet 7 is provided on the top of the transmission box 5. The ratchet 7 is fixedly connected to the surface of the gear rod 6. A protective cover 18 is provided on the surface of the ratchet 7 and the check plate 8. The protective cover 18 is fixedly installed on the top of the transmission box 5. By providing the protective cover 18, the ratchet 7 and the check plate 8 can be protected to prevent damage caused by collision between foreign objects and the ratchet 7. The right side of the top of the transmission box 5 is hinged with a check plate 8 through a pin rod. The check plate 8 is engaged with the ratchet 7. A spring plate 9 is provided on the back of the check plate 8. A connecting plate 10 is fixedly installed on the back of the spring plate 9. , both sides of the back of the connecting plate 10 are fixedly connected with a triangular plate 19, and the bottom of the triangular plate 19 is fixedly connected to the top of the transmission box 5. By setting the triangular plate 19, the connection strength between the connecting plate 10 and the transmission box 5 can be increased to prevent the connecting plate 10 from breaking during the operation process.

[0036] Reference Figure 2 A protective component is provided on the surface of the ventilation hose 4, and the protective component includes a clamp 13. The clamp 13 is fixedly connected to the front of the hemostatic cuff body 1. The ventilation hose 4 is located inside the clamp 13. A threaded ring 14 is fixedly connected to the left side of the surface of the ventilation hose 4. The surface of the threaded ring 14 is threadedly connected to a threaded sleeve 15. With the mutual cooperation of the clamp 13, the threaded ring 14 and the threaded sleeve 15 structures, the ventilation hose 4 can be conveniently stored.

[0037] Reference Figure 2 A limiting assembly is provided inside the transmission box 5, and the limiting assembly includes a limiting wheel 16. The limiting wheel 16 is fixedly connected to the top and bottom of both sides of the transmission box 5. The top and bottom of the nylon toothed belt 3 are fixedly connected to the limiting guide rail 17. The limiting wheel 16 and the limiting guide rail 17 are used in conjunction with each other. By setting the limiting wheel 16 and the limiting guide rail 17, the hemostatic cuff body 1 can be limited to prevent the hemostatic cuff body 1 from shaking during work.

[0038] Working principle: When in use, first wrap the hemostatic cotton gauze 2 around the bleeding part of the patient, then press the transmission box 5 against the surface of the hemostatic cotton gauze 2, and at the same time, send the hemostatic cuff body 1 away from the end of the transmission box 5 into the interior of the transmission box 5, and the hemostatic cuff body 1 drives the nylon toothed belt 3 to enter the interior of the transmission box 5, and the nylon toothed belt 3 drives the gear rod 6 inside the transmission box 5 to rotate, and the gear rod 6 drives the ratchet 7 to rotate, and the ratchet 7 pushes the check plate 8 to move to the side close to the shrapnel 9, and at the same time the check plate 8 compresses the shrapnel 9, and after the hemostatic cuff body 1 moves to the appropriate position, the shrapnel 9 is pushed by its own elastic force The check plate 8 returns to its original position to clamp the ratchet 7. When the binding pressure of the hemostatic sleeve body 1 is too large and needs to be adjusted, the rotating rod 12 is pushed. The rotating rod 12 drives the eccentric wheel 11 to rotate around the pin rod. The eccentric wheel 11 pushes the check plate 8 to move to the side away from the ratchet 7 while compressing the shrapnel 9, and then moves the hemostatic sleeve body 1 in the opposite direction. After the hemostatic sleeve body 1 moves to the appropriate position, the rotating rod 12 is released. The shrapnel 9 pushes the check plate 8 to move by its own elastic force. The check plate 8 pushes the eccentric wheel 11 to return to its original position and clamps the ratchet 7, thereby facilitating and quickly adjusting the binding pressure of the hemostatic sleeve body 1.
