Negative pressure assist device for soft bag infusion

Abstract

The invention provides a negative pressure assist device for soft bag infusion, which comprises a bearing plate, a first angle aluminium, a second angle aluminium, a third angle aluminium, a press roll, a pressure regulator, a reel, a power supply, a switch, a potentiometer, a motor, a first gear and a second gear, wherein the first angle aluminium, the second angle aluminium, the third angle aluminium, the press roll and the pressure regulator are fixed on the bearing plate; the reel is arranged on the first angle aluminium and the second angle aluminium; the power supply, the switch, the potentiometer and the motor are connected in series; the motor and the first gear are arranged on the third angle aluminium; the second gear and the reel are arranged on the first angle aluminium and the second angle aluminium; the reel is provided with a clamping device; the press roll is positioned below the reel; both ends of the pressure regulator are fixed on the bearing plate and the middle part of the pressure regulator is arranged across the press roll and is pressed on the press roll. According to the invention, power for generating a negative pressure can be provided for an infusion soft bag, so that the infusion soft bag does not need to be suspended; the negative pressure assist device is convenient to use, is particularly suitable for the use requirement for long-time outdoor or field rescue and particularly rescue on patients suffering from injuries caused by war and natural disasters, is low in manufacturing cost and can be repeatedly used.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a negative pressure assistant for soft bag infusion. Background technique [0002] At present, during infusion, most of the infusion bottles or infusion bags need to be hung at a position higher than the patient, so as to increase the pressure of the liquid medicine, ensure that the liquid medicine flows into the patient's vein, and prevent blood return. And in poorly equipped outdoors or in the field, then do not have the condition of hanging infusion bottle or infusion bag, therefore need a kind of infusion device that does not need to hang people to be able to infuse normally. In recent years, through the efforts of technicians, corresponding products have been developed. For example, the utility model patent "negative pressure infusion device" whose notification number is CN202105252U. In this patent, the infusion bag is set in a U shape, and a telescopic device is arranged...

Problems solved by technology

Although this patent realizes the normal completion of the infusion without hanging the infusion bag, the U-shaped infusion bag is only placed on the patient's arm, which may easily cause discomfort to the patient and affect blood circulation.
