Description
Technical field
This utility model relates to a kind of improved hemostasis device.
Background technology
In surgical operation,, often need tie up hemostasis device at the near-end of limbs in order to reduce losing blood of patient, for the limbs that prevent patient were lost blood of a specified duration, cause limb necrosis, after 30～50 minutes, also must unclamp hemostasis device and then tie up hemostasis device after about 1 minute again and stop blooding.The upper limb tourniquet pressure is: (32.25～39.90Kpa), the lower limb tourniquet pressure is 400～500mmhg (53.20～66.50Kpa) to 250～300mmhg.
Present hemostasis device generally includes the tourniquet that has air bag, and air bag connects inflatable ball by gas tube.But because the pressure of tourniquet is subjected to influence of various factors, influence as people's blood pressure, sex, fat or thin degree, the pressure control difficulty of tourniquet, pressure is little, will not have the hemostatic effect, and pressure is big, will cause nerve injury, dark venous injury hyperamization bolt incidence rate height, muscle and other soft tissue injury, the weak effect of use.
In order to address the above problem, someone improves above-mentioned hemostasis device, increased the pressure detecting devices, make gas tube communicate with the Pressure gauge of pressure detecting devices, thereby pressure by the gauge measurement tourniquet, the control tourniquet is in a preferable force value to the pressure of limbs, reduces the injury to nervous tissue and other soft tissue as much as possible.
As the disclosed a kind of self-control type tourniquet of Chinese patent literature CN101156799 " self-control type tourniquet ", this self-control type tourniquet comprises the aeration zone that has air bag, connecting a gas tube on the aeration zone also communicates with it, being connected with Doppler's blood vessel survey meter on the gas tube also communicates with it, have doppler transducer on Doppler's blood vessel survey meter, have Pressure gauge on Doppler's blood vessel survey meter, gas tube communicates with Pressure gauge, have aerating device on Doppler's blood vessel survey meter, gas tube communicates with aerating device.
But, this scheme also must manually be operated by the people every 30～50 minutes, and the gas in the air bag is bled off, unclamp hemostasis device after about 1 minute, follow inflating homeostasis again, these operations can't be carried out automatically, and it is still convenient inadequately therefore to use, in case the medical personnel is too busy, the time of having delayed aforesaid operations, it is of a specified duration just might to cause patient's limbs to be lost blood, even causes the serious consequence of limb necrosis.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of improved hemostasis device is provided, and behind the inflating homeostasis, unclamps hemostasis device automatically for a moment every one period that configures, and then follows inflating homeostasis, and the technical scheme of employing is as follows:
Improved hemostasis device of the present utility model, comprise tourniquet, gas flesh, gas tube, pressure detecting devices and aerating device, the gas flesh is installed on the tourniquet, the gas flesh connects aerating device by gas tube, the pressure detecting devices is communicated with gas tube, it is characterized in that: also comprise control device, the signal output part of described pressure detecting devices connects the signal input part of control device, and the control signal output ends of control device connects the control signal input of aerating device; The pressure detecting devices flows to control device with the force value that detects, and control device carries out carrying control signal to give aerating device after the analytical judgment to this force value, and the control aerating device is inflated or exitted.The medical worker opens hemostasis device, aerating device is inflated the gas flesh, the pressure detecting devices is surveyed the pressure (also being the pressure of air bag to tourniquet) of air bag and the force value signal is flowed to control device, when the pressure of air bag has arrived proper value (predefined force value), control device just cuts out aerating device, and the continual compression cord of air bag makes tourniquet keep suitable pressure to patient's limbs, thereby stops blooding; Spent a period of time (30～50 minutes), control device control aerating device bleeds off the gas in the air bag, unclamp hemostasis device for a moment after (about 1 minute), control device is controlled aerating device again and then the gas flesh is inflated, the pressure detecting devices is surveyed the pressure (also being the pressure of air bag to tourniquet) of air bag and the force value signal is flowed to control device, when the pressure of air bag has arrived proper value (predefined force value), control device just cuts out aerating device, and the continual compression cord of air bag, make tourniquet keep suitable pressure, thereby stop blooding patient's limbs.
Described aerating device is an air pump.
Described pressure detecting devices is Doppler's blood vessel survey meter.Can certainly adopt other available pressure detecting devices such as air gauge.
In order to change parameters such as predefined force value according to practical situation, described improved hemostasis device also comprises data input device, the data output end of data input device connects the data input pin of control device, and data input device flows to control device with data.
Described data input device is a keyboard.
This utility model beneficial effect against existing technologies is, owing to be provided with control device, therefore hemostasis device can bleed off the gas in the air bag at set intervals automatically, unclamps hemostasis device one after the meeting, then inflation again, stop blooding, very easy to use, the situation of having avoided patient's limbs to lose blood of a specified duration effectively occurs, more can not cause the serious consequence of limb necrosis, significantly alleviate medical personnel's burden simultaneously yet.
