TECHNICAL FIELD

[0001] The present application belongs to the field of medical equipment, in particular to a non-gravity self-pressure infusion device. BACKGROUND

[0002] In some more serious conditions, the patient needs to be treated by infusion, that is, a large dose of injection is input into the body by intravenous drip, and the dosage is more than 100ml, and generally a infusion bottle or bag is used.

[0003] Generally, the infusion bottle or bag needs to be hung on the infusion stand or a high place, and slowly input into the patient's vein under the action of gravity through the infusion tube. However, the infusion process is very long, and a large amount of injection is input into the body, so the patient is bound to go to the toilet or do other things during the infusion process, which makes the traditional infusion device very troublesome for the patient's activities, and the patient cannot move freely, and needs to pay attention to prevent the infusion stand from falling down during the movement, which is very inconvenient to use.

[0008] By this scheme, the infusion bag is placed in the containing cavity, and after the infusion tube is stretched out through the infusion channel, the pressing drive mechanism is started to apply pressure to the infusion bag by the pressing plate, so as to simulate gravity to complete infusion, and the device does not need to be hung at a high place for infusion.

[0009] Preferably, the fixed box comprises a base and a box cover, the base and the box cover jointly enclose the containing cavity, one end of the base and the box cover is hinged, and the other end is buckled.

[0013] Preferably, the extrusion driving mechanism comprises a driving motor, a screw rod and a driving plate, driving cavities are arranged on both sides of the accommodating cavity, the driving motor drives the screw rod to rotate in the driving cavity, one end of the driving plate is threadedly connected with the screw rod, and one end of the driving plate extends out of the driving cavity to connect the extrusion plate.

[0014] Through the scheme, when the driving motor drives the screw rod to rotate, the driving plate keeps a fixed angle under the limitation of the accommodating cavity, and thus moves up and down along the rotation of the screw rod, thereby driving the extrusion of the extrusion plate.

[0015] Preferably, the driving cavity is polygonal, one end of the driving plate is provided with a polygonal sliding block, and the sliding block is slidingly connected into the driving cavity and threadedly connected with the screw rod.

[0016] Through the scheme, the polygonal driving cavity can keep a fixed angle with the sliding block, avoiding the problem of reduced service life caused by stress at the connection with the driving plate.

[0017] Preferably, a pressure plate is arranged on the box cover, and the pressure plate is connected to the box cover through a pressure sensor.

[0019] Preferably, a controller is further included, the controller comprises a display, a processor and an input device, the processor is used for collecting data of the pressure sensor and controlling the extrusion driving mechanism.

[0020] Through the scheme, the pressure of the extrusion plate is adjusted by the controller, so that the speed of infusion is adjusted, and infusion in different environments for different people is suitable.
