Description

Improved Hemostasis Device

technical field

The utility model relates to an improved hemostasis device.

Background technique

In surgery, in order to reduce the patient’s blood loss, it is often necessary to bind the hemostatic device at the proximal end of the limb. In order to prevent the patient’s limb from bleeding for a long time, resulting in limb necrosis, the hemostatic device must be loosened after every 30 to 50 minutes. After 1 minute, the hemostatic device was tied for hemostasis. The upper extremity tourniquet pressure is 250-300mmhg (32.25-39.90Kpa), and the lower extremity tourniquet pressure is 400-500mmhg (53.20-66.50Kpa).

Current hemostatic devices usually include a tourniquet with an air bag connected to an inflatable ball through an inflatable tube. However, because the pressure of the tourniquet is affected by many factors, such as people's blood pressure, gender, and degree of obesity, it is difficult to control the pressure of the tourniquet. If the pressure is small, the effect of hemostasis will not be achieved. It can cause nerve damage, high incidence of thrombosis caused by deep vein injury, muscle and other soft tissue damage, and the effect of use is poor.

In order to solve the above problems, someone has improved the above-mentioned hemostatic device by adding pressure detection equipment, so that the inflatable tube communicates with the pressure gauge of the pressure detection equipment, thereby measuring the pressure of the tourniquet through the pressure gauge, and controlling the pressure of the tourniquet on the limbs. A better pressure value to minimize damage to nerve tissue and other soft tissues.

For example, a self-control tourniquet disclosed in Chinese patent document CN101156799 "self-control tourniquet", the self-control tourniquet includes an inflatable belt with an air bag, an inflatable tube is connected to the inflatable belt and communicated with it, and the inflatable tube is connected Doppler blood vessel detector and communicate with it, Doppler blood vessel detector has Doppler probe, Doppler blood vessel detector has pressure gauge, inflatable tube communicates with pressure gauge, Doppler blood vessel detection There is an inflatable device on the instrument, and the inflatable tube communicates with the inflatable device.

However, every 30 to 50 minutes, this solution must be manually operated by a person to let go of the air in the airbag, loosen the hemostatic device for about 1 minute, and then inflate the hemostatic device. These operations cannot be performed automatically, so it is still not enough Convenience, once the medical workers are too busy and delay the time of the above operations, it may cause the patient's limbs to lose blood for a long time, and even cause serious consequences of limb necrosis.

Contents of the invention

The purpose of this utility model is to improve the existing technology and provide an improved hemostatic device.

When the pressure of the air bag reaches a more appropriate value ( Pre-set pressure value), the control device will close the inflatable device, and the air bag will continue to press the tourniquet, so that the tourniquet maintains an appropriate pressure on the patient's limbs, so as to stop bleeding; after a period of time (30 ~ 50 minutes), the control device controls the inflation device to release the air in the air bag, and after releasing the hemostatic device for a while (about 1 minute), the control device controls the inflation device and then inflates the air bag, and the pressure detection device detects the pressure of the air bag ( It is also the pressure of the airbag on the tourniquet) and the pressure value signal is sent to the control device. When the pressure of the airbag reaches a more appropriate value (preset pressure value), the control device closes the inflation device, and the airbag continues to Compress the tourniquet so that the tourniquet maintains proper pressure on the patient's limb to stop bleeding.

The inflation device is an air pump.

The pressure detecting device is a Doppler blood vessel detector. Of course, other available pressure detection equipment such as a barometer may also be used.
