Detailed Description
As shown in fig. 2, the conventional constant-pressure infusion device has an infusion bag 2 hung on one stand 100, and of course, if the device is blood, the infusion bag is a blood transfusion bag, and if the device is a drug solution, the infusion bag 2 is a drug solution, and in the present embodiment, such an infusion bag 2 can be used regardless of blood or drug solution, and hereinafter, the infusion bag 2 is collectively referred to as an infusion bag 2. The constant pressure bag 1 is sleeved outside the infusion bag 2, the constant pressure bag 4 is used for detecting the pressure intensity (pressure) in the constant pressure bag 1, the constant pressure bag 1 is also connected with a squeezer 3 through an air pipe, and the squeezer 3 is the same as the squeezer 3 used in the sphygmomanometer. In this embodiment, a pressure sensor 6 is disposed in the constant pressure bag 1, and a controller and a pressurizing device 5 are further disposed, the pressure sensor 6 is connected to the control device, the control device controls the pressurizing device 5 to increase the pressure in the constant pressure bag 1 when the pressure in the constant pressure bag 1 detected by the pressure sensor 6 is smaller than a set minimum pressure threshold, and to stop pressurizing when the pressure in the constant pressure bag 1 reaches the set maximum pressure threshold. In the embodiment, the pressurizing device 5 is an air pump which is directly connected with an air pipe of the extruder 3 communicated with the constant pressure bag 1, and the air pump pressurizes the constant pressure bag 1 from the same air pipe without changing the air inlet interface of the constant pressure bag 1, so that the full-automatic constant pressure infusion device keeps the maximum degree of identity with the original manually operated constant pressure infusion, and is convenient for medical staff to use. The air pump is a commercially available air pump, and at present, many products are available as long as the output pressure is slightly higher than the set maximum. In addition, as a fully automatic device, the infusion device in the embodiment further comprises an infusion ending alarm device, the infusion ending alarm device is connected with the control device, and the control device controls the infusion ending alarm device to give an alarm when the real-time pressure in the constant pressure bag 1 output by the pressure sensor 6 is kept constant within the set time.
In this embodiment, the constant pressure bag 1 may be a cuff in a sphygmomanometer, and the cuff wraps the infusion bag, so that the size of the bag can be adjusted according to the volume of liquid (liquid medicine/blood) in the infusion bag, and the bag is convenient to use.
