Description

一种股动脉压迫止血装置Femoral artery compression hemostasis device 技术领域Technical field
本发明涉及一种医疗止血器，具体涉及一种用于股动脉的一次性压迫止血器，属于医疗器械技术领域。The invention relates to a medical hemostat, in particular to a disposable compression hemostat for a femoral artery, belonging to the technical field of medical instruments.
背景技术Background technique
介入手术已经是心脏内科、神经内科等医疗科室的常规治疗手段，介入手术的优点在于医生可在不使用全身麻醉剂或不需要开刀手术的情况下进入患者身体内进行治疗。在通常情况下，介入诊断和治疗的手术，尤其是神经内外科的介入手术，是通过患者的股动脉通路来实现的，股动脉通路的介入手术具有成功率高，手术操作难度低等优点，但由于股动脉的血管较粗，血压高，因而术后的动脉完全止血是具有挑战性的。Interventional surgery is a routine treatment for medical departments such as cardiology and neurology. The advantage of interventional surgery is that the doctor can enter the patient's body without using general anesthesia or without surgery. Under normal circumstances, interventional diagnosis and treatment, especially neurosurgical interventional surgery, is achieved through the patient's femoral artery access. The interventional procedure of the femoral artery has the advantages of high success rate and low difficulty in operation. However, due to the thick blood vessels of the femoral artery and high blood pressure, it is challenging to completely stop bleeding after the operation of the artery.
通常介入手术完成，导管去除后，由医生或医疗专业人员在动脉导管穿刺点处施加压力以实现止血和动脉穿刺点的闭合，止血和动脉穿刺点闭合需要持续稳定的压力，一般初期给予的压力较高，经过一段时间后，需要逐渐降低压力，使血管下游组织得到丰富的血供。通常股动脉穿刺点止血主要通过医护人员手工按压或施加绷带加压止血，但极耗费医护人员体力和时间，而且在实施加压包扎时，国内医生使用的材料也不尽相同，如使用通用绷带需"十"字形缠绕夺权才能有效，而且绷带会勒紧皮肤，造成患者皮肉疼痛，也有用宽而长的医用胶布"十"字交叉粘贴，但较多的患者存在胶布过敏情况。同时医生限于无专用器材，只好自制"加压物"垫于穿刺点上，使加压压力能够集中于穿刺点。但问题在于，其一，自制的加压物大小质量不一，很难保证止血作用:其二，过大的加压物还会压迫相邻的股静脉，引起静脉回流障碍甚至血栓形成，材料的不统一和非专用器材的应用，使包扎止血的效果和质量无法保证，其三，绷带或胶布加压前均需要医护人员手工压迫10～30分钟，耗时耗力。Usually the interventional procedure is completed. After the catheter is removed, the doctor or medical professional applies pressure at the arterial catheter puncture point to achieve hemostasis and closure of the arterial puncture point. The hemostasis and arterial puncture point closure require a constant pressure, usually the initial pressure. Higher, after a period of time, it is necessary to gradually reduce the pressure, so that the blood vessels downstream tissue get rich blood supply. Usually, the hemostasis of the femoral artery puncture is mainly controlled by the medical staff by manual pressing or applying a bandage to stop bleeding, but it is very labor-intensive and time-consuming, and the materials used by domestic doctors are different when performing pressure dressing, such as the use of universal bandages. It is necessary to use the "ten" shape to win the power, and the bandage will tighten the skin, causing pain in the patient's skin. It also has a wide and long medical tape "10" cross-paste, but more patients have allergies of the tape. At the same time, the doctor is limited to no special equipment, and has to make a "pressure" pad on the puncture point so that the pressure can be concentrated at the puncture point. However, the problem is that, first, the quality of the self-made pressurized material is different, it is difficult to ensure the hemostasis: Second, the excessive pressure will also oppress the adjacent femoral vein, causing venous return disorder and even thrombosis, material The application of non-uniform and non-specialized equipment can not guarantee the effect and quality of dressing and hemostasis. Third, the bandage or tape needs to be manually pressed by the medical staff for 10 to 30 minutes before being pressurized, which is time-consuming and labor-intensive.
现有的机械加压设备一般通过气囊或者旋钮进行充气或者推进加压，可以减轻医护人员的体力，提高止血效率，但该类设备存在3个显著问题，一是止血效果较差，止血成功率没有手工按压高，渗血情况较多；二是只能压住皮肤穿刺点，无法压住血管穿刺口，撤除加压装置后，皮内血肿较多；三是加压力度不稳定，容易随着病人腿部的转动而产生位移，从而导致加压压力偏移穿刺点。The existing mechanical pressure equipment is generally inflated or pushed and pressurized by the airbag or the knob, which can reduce the physical strength of the medical staff and improve the hemostasis efficiency, but there are three significant problems in the equipment, one is that the hemostasis effect is poor, and the hemostasis success rate There is no manual pressure high, and there is more oozing; the second is that it can only press the skin puncture point, can not hold the vascular puncture mouth, remove the pressure device, the intradermal hematoma is more; the third is the unstable pressure, easy to follow The rotation of the patient's leg causes displacement, causing the compression pressure to shift the puncture point.

Adhesive dressing on the compression pad, the hemostatic dressing is a freeze-dried sponge containing hemostatic drugs, which has a good water absorption effect. When the pressure is applied, the hemostatic dressing directly contacts the puncture mouth, thereby blocking and stopping the puncture and puncture channel, reducing the probability of puncture point bleeding, thereby solving the problem that the puncture point is easy to ooze blood;
4、压迫垫为非对称结构，一边为止血敷料，一边为血管压迫垫，卡扣位于血管压迫垫和止血敷料接触面的上方，血管压迫垫施加的压迫力可直接压迫血管穿刺口，并且加压旋钮的加压力度可以主要集中在血管压迫垫，由于血管压迫垫高度不小于止血敷料的高度，从而使压力进一步集中在血管压迫垫，促使血管穿刺口封闭；4, the compression pad is an asymmetric structure, one side of the blood dressing, one side of the vascular compression pad, the buckle is located above the contact surface of the vascular compression pad and the hemostatic dressing, the compression force exerted by the vascular compression pad can directly compress the vascular puncture, and add The pressing force of the pressure knob can be mainly concentrated on the vascular compression pad, because the height of the vascular compression pad is not less than the height of the hemostatic dressing, so that the pressure is further concentrated on the vascular compression pad, and the vascular puncture port is closed;
5、支撑稳定杆、尾翼和腿部支撑板均与腿部的结构相吻合，使固定单元稳定固定在腿部并且不易与腿部产生相对位移；支撑稳定杆以使固定带的加压压力更好集中于前部加压旋钮；尾翼呈蝶形，与腿部有较大的接触面积，可以显著分散压迫力，从而减少止血装置对静脉的压迫，不影响血液回流，尾翼同时起稳定支撑稳定杆的作用。5. The support stabilizer bar, the tail wing and the leg support plate are all in conformity with the structure of the leg, so that the fixing unit is stably fixed on the leg and is not easy to be displaced relative to the leg; the stabilizer bar is supported to make the pressing pressure of the fixing band more It is concentrated on the front pressure knob; the tail has a butterfly shape and has a large contact area with the leg, which can significantly disperse the compression force, thereby reducing the compression of the vein by the hemostatic device, does not affect the blood return, and the tail is stable at the same time. The role of the pole.
