Technical Field
The utility model relates to an infusion pressure regulating constant voltage equipment belongs to medical instrument technical field.
Background
With the aging of society, the incidence of cardiovascular diseases is higher and higher, and the incidence of chronic occlusive diseases among patients with coronary heart disease is higher and higher. For such patients, rotational atherectomy may be used during the opening of the blood vessel, and medical aids that can continuously provide saline flush under pressure are needed during the operation; in addition, continuous pressure infusion is also very commonly used in various critical and critical patients. The method adopted clinically in the process of needing pressurized transfusion at present is as follows: the latex ball is held by hand to charge air into the pressurizing bag to reach corresponding pressure. This method has significant limitations: the use pressure of the pressurizing bag is 150Kpa and 300Kpa, the latex ball is normally held by a hand to be inflated, about 13 seconds are needed for inflating to 150Kpa, about 25 seconds are needed for inflating to 300Kpa, the pressurizing time is long, and the medical care personnel can easily feel operation fatigue in the operation process. Secondly, the pressure of the pressurizing bag acting on the infusion bag can be gradually reduced along with the reduction of the liquid medicine amount in the infusion process, so that the flow rate of the liquid medicine in the infusion process is unstable. And thirdly, in the process of pressurizing infusion, a medical worker needs to take care of the infusion, and when the pressure is not enough, the latex ball needs to be manually pressed again to keep the pressure, so that the stable outflow of the liquid medicine in the infusion process is ensured. Fourthly, in the process of pressurized infusion, medical care personnel need to manually hold the latex ball for many times to keep pressure, and the pressurizing bag is filled repeatedly, so that the serious consequence of venous air embolism is caused.
Disclosure of Invention
The utility model aims at solving the technical problems that the prior pressurized transfusion needs manual pressurization and the pressure is not constant. In order to solve the above problems, the utility model adopts the technical proposal that an infusion pressure-regulating constant-pressure device is provided, which is characterized in that: comprises a gas pressure regulator, a gas inlet pipe, a gas outlet pipe, a standard Ruhr joint and a pressurizing bag; one end of the air inlet pipe is connected with an oxygen connector, the other end of the air inlet pipe is connected with an air inlet of the air pressure regulator, an air outlet of the air pressure regulator is connected with an air outlet pipe, and the air outlet pipe is connected with the pressurizing bag through a standard Ruhr connector.
Preferably, the gas pressure regulator is provided with a pressure reducing valve, a pressure gauge and a gas pressure adjusting knob.
Preferably, the pressurizing bag is provided with a simple pressure gauge.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model is simple in operation, the pressure is not required to be confirmed many times by manpower in the process of infusion, and the working strength of medical personnel is reduced.
2. Because the oxygen device is the necessary medical equipment of hospital, the utility model discloses the air supply source of device is convenient.
3. The utility model discloses the device is simple and convenient, and is high-efficient reliable, convenient using widely.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings. As shown in figure 1, the utility model provides an infusion pressure regulating constant pressure device which is characterized in that: comprises a gas pressure regulator 1, a gas inlet pipe 2, a gas outlet pipe 5, a standard Ruhr joint 3 and a pressurizing bag 4; one end of the air inlet pipe 2 is connected with an oxygen connector which can be directly connected to an oxygen outlet port provided by a hospital at present, the other end of the air inlet pipe is connected with an air inlet of the air pressure regulator 1, an air outlet of the air pressure regulator 1 is connected with an air outlet pipe 5, the other end of the air outlet pipe 5 is connected with a standard luer connector 3, and then the standard luer connector 3 and the pressurizing bag 4 are connected through another hose. The gas pressure regulator 1 is provided with a pressure reducing valve, a pressure gauge and a gas pressure adjusting knob. The pressure adjusting knob is rotated according to the requirement, and the pressure is adjusted to the required pressure value through the pressure reducing valve and the pressure adjusting knob according to the display of the pressure gauge on the gas pressure regulator 1. The pressurizing bag 4 is also provided with a simple pressure gauge 6 for verifying the pressure.
The utility model relates to an infusion pressure regulating constant voltage equipment's use: this infusion pressure regulating constant voltage equipment initiating terminal uses the intake pipe 2 connection that a supporting oxygen connects on hospital's oxygen port, then connects into the gas regulator 1 of 2 access devices of intake pipe, through the pressure valve adjustment pressure of gas regulator 1 to required scope, connects on a standard luer connects 3 through outlet duct 5. And then another hose is connected to the pressurizing bag 4 through the luer 3. When the infusion bag is used, the oxygen end of a hospital is used as a pressure source, oxygen is filled into the pressurizing bag 4 after the constant pressure device for infusion is adjusted to 150Kpa within 5S, the pressurizing bag 4 is used as an infusion bag again, and the pressurizing infusion process is completed. In the whole infusion process, the pressure in the pressurizing bag is kept under the set pressure through the infusion pressure-regulating constant-pressure device, and when the pressure is reduced, the device can timely supplement gas to ensure the pressure in the pressurizing bag to be stable.
Medical personnel only need be connected to the oxygen port of hospital to the articulate of one end when operation infusion pressure regulating constant voltage equipment, and the other end is connected to the pressurization bag, just can realize constant voltage infusion control, simple operation behind the adjustment gear.
