Description

arterial compression hemostatic device

technical field

The utility model relates to a medical instrument, in particular to a device for hemostasis at an artery puncture site.

Background technique

In recent years, with the continuous development of interventional technology, arterial puncture technology has been widely used clinically. In the puncture treatment of radial artery and femoral artery, if the hemostasis at the puncture site is not handled properly, it is easy to cause blood circulation disorder in the hand, and in severe cases, it may cause ischemic necrosis.

According to relevant literature reports, the local complication rate caused by the hemostatic treatment of puncture is as high as 37.5%. After radial artery puncture intervention, the traditional methods for local hemostasis include: compressing with hands to stop bleeding, wrapping with gauze to stop bleeding, and using elastic sticking fixed bandages to stop bleeding, etc. All the above methods of hemostasis have different disadvantages:

1. The operation is cumbersome, time-consuming and laborious; 2. The condition of the wound is not easy to observe; 3. The tightness of the dressing is not easy to control; 4. It is easy to affect the venous blood return, causing numbness, swelling, congestion, etc. of the extremities; Damage, etc.; 6. Increase the suffering of patients and the difficulty of nursing work.

In the prior art, there are elastic band pressurized hemostats and air bag pressurized hemostats, and the elastic band pressurized hemostat only adjusts the pressure by adjusting the tightness of the elastic band, which is inconvenient to operate and difficult to control; The air bag pressurized hemostat uses the air bag to pressurize the hemostatic site. The pressurized contact area is large, which is not conducive to hemostasis, affects the return of venous blood, and easily causes local skin allergic reactions; in addition, the elastic band pressurized hemostat and air bag add Compression-type hemostats are also more expensive.

In the prior art, there is also a tourniquet, which only uses screw rotation to pressurize the hemostatic site, and cannot intuitively judge the amount of pressurization, which may easily cause excessive pressurization and cause adverse effects on patients.

Detailed ways

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Figure 1, the arterial compression hemostasis device of the present invention includes a pinch plate 5, an indicating bag 9, a hemostatic bag 6, a screw cap 1, and a push rod 2. In the hollow space, the inner surface of the screw cap 1 is provided with internal threads, and the outer surface of the pinch plate 5 is provided with external threads. The cap 1 can rotate up and down along the buckle plate 5, and the push rod 2 abuts on the lower surface of the screw cap 1. Poisonous liquid, such as water, is also provided with the fixing belt 7 that is used for fixing the hemostatic position at the lower end of buckle plate 5.

Among them, a rubber plug 3 is sandwiched between the outer edge of the indicating bag 9, the push rod 2 and the screw cap 1, and the rubber plug 3 acts as a buffer; There is also a gland 4 between them, and the gland 4 is adapted to the push rod 2; a screw cap 8 is also sandwiched between the outer edge of the indicator bag 9, the rubber plug 3 and the screw cap 1, and the screw cap 8 plays a role. Fixation indicates the function of capsule 9 .

Preferably, the capsule wall of the indicating capsule 9 is thinner than the capsule wall of the hemostatic capsule 6, and the capsule wall of the indicating capsule 9 is white; the hemostatic capsule 6 is made of transparent silicone rubber material; the buckle plate 5 and the screw cap 1 are both made of transparent materials production.

The working principle of the utility model is: open the arterial compression hemostatic device, paste the inner surface of the hemostatic bag 6 above the artery puncture point, and fix the arterial compression hemostatic device by the fixing belt 7 . Rotate the screw cap 1 downward, and the screw cap 1 acts on the push rod 2, so that the push rod 2, the gland 4, and the buckle plate 5 press the hemostatic bag 6 and the indicator bag 9 toward the middle, because the hemostatic bag 6 and the indicator bag 9 are filled with With water, under the action of pressure, the hemostatic bag 6 will expand downward, and the indicating bag 9 will expand upward, and the hemostatic bag 6 will exert pressure on the arterial puncture point. Finally, because the pinch plate 5 and the hemostatic bag 6 are made of transparent materials, the bleeding situation at the puncture point can be directly observed, and the patient's feeling situation can be inquired at the same time, and the pressure can be adjusted appropriately by the screw cap 1. If there is no bleeding at the puncture point and the patient feels comfortable, then stop rotating the screw cap 1 .

Depending on the diameter of the puncture tube, the pressurization time is between 1 hour and 4 hours. If there is no abnormality after 4 hours, you can gradually turn the nut 1 upwards in the "back" direction to reduce the pressure on the puncture point, and release it after 12 hours. After applying pressure and confirming that there is no bleeding at the puncture point, remove the arterial compression hemostatic device, and protect the puncture point with sterile gauze or sterile dressing.

During the downward rotation of the screw cap 1, since the indicating capsule 9 expands upwards, and the capsule wall of the indicating capsule 9 is thinner than that of the hemostatic capsule 6, the capsule wall of the indicating capsule 9 is white, so during the expansion process , indicating that the color of the capsule wall of the capsule 9 gradually becomes lighter and more transparent, which is convenient for the medical staff to judge the size of the pressure, and avoid the risk of causing pain to the patient due to excessive pressure or too little pressure.

The utility model can flexibly adjust the pressure by rotating the screw cap 1, and can adapt to the individual differences of different patients and the differences of different puncture methods, so that the operation of postoperative compression and hemostasis is simple and practical.

The hemostatic sac of the utility model is made of soft and transparent silicon rubber material, and can accurately pressurize the puncture site without compressing the ulnar artery, without fixing the patient's limbs, thereby greatly reducing the pain of the patient.

What is disclosed above is only a specific embodiment of the utility model, but the utility model is not limited thereto, and any changes conceivable by those skilled in the art should fall within the protection scope of the utility model.
