Problems solved by technology

During the operation of the motor, the control accuracy of the encoder is easy to lose steps and is easily disturbed by the magnetic field, which will cause the medicine to enter the patient's body at a uniform speed and accurately, which will affect the patient's health.
[0005] In addition, if a large motor is used, not only the volume of the entire infusion pump will become larger, but also its power consumption will be higher; if a small motor with a small volume is used, it will be more difficult to manufacture and the cost will be higher
Either way will result in increased cost

Embodiment Construction

[0021] The present invention will be further described below in combination with specific embodiments.

[0022] Such as figure 1 As shown, the present invention discloses a power device installed in an infusion pump. The power device includes a reset member 1 , an electrified deformable member 2 , a liquid storage chamber 3 , a first one-way valve 4 and a second one-way valve 5 .

[0023] The reset part 1 is connected to the energized deformable part 2. The connection is such that the energized deformable part 2 can drive the reset part 1 to generate torque when the energized deformable part 2 is de-energized and deformed. The reset part 1 is not affected by the energized deformable part 2. Restoring the original position is the basis, and the electrified deformable part 2 can be driven by the reset part 1 to restore the shape before electrification. In actual operation, the reset member 1 and the electrified deformable member 2 may be fixedly connected by pasting, or fixedl...

Abstract

The invention discloses a power device. The power device is used for an infusion pump. The power device comprises a reset piece, an electrification deformation piece, a liquid storage cavity, a firstone-way valve and a second one-way valve. The reset piece is connected with the electrification deformation piece. The liquid storage cavity is provided with a deformation part, a liquid inlet and a liquid outlet, the electrification deformation part is connected with a deformation part of the liquid storage cavity, one end of the first one-way valve is connected with the liquid inlet of the liquid storage cavity and transmits medicine into the liquid storage cavity in a one-way mode, one end of the second one-way valve is connected with the liquid outlet of the liquid storage cavity, and themedicine in the liquid storage cavity is transmitted to the second one-way valve. According to the power device, the reset piece, the electrification deformation piece and the one-way valve are ingeniously utilized to form the power device, a motor in the prior art is replaced, the structure is simple, and the manufacturing and using cost is low; and the use is safe, stable and reliable.

Description

technical field [0001] The invention belongs to the field of drug infusion devices, and more specifically relates to a power device. Background technique [0002] The infusion pump is a device that can accurately control the number of infusion drops or the flow rate of the infusion, so as to ensure that the drug can enter the patient's body safely and play a role at a uniform speed and accurate dosage. The existence of the infusion pump improves the efficiency and flexibility of clinical drug administration operations and reduces the workload of nursing. [0003] The clinical diagnosis of diabetes can be divided into type 1 diabetes and type 2 diabetes. Type 1 diabetes, also known as insulin-dependent diabetes, usually appears in childhood or adolescence, and is a disease that is inherited in families. Type 1 diabetes is an autoimmune disease in which the body's immune system attacks the beta cells in the body that produce insulin, eventually resulting in the body not bein...
