Example Embodiment

[0019] The technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0020] Such as figure 1 As shown, the specific implementation of the present invention is to construct an infusion pump based on piezoelectric drive, which is characterized by comprising: a liquid inlet 1, a liquid outlet 2, a cavity 3 for containing liquid, and a piezoelectric vibrator 4. At least one end surface of the cavity 3 is an elastic end surface, the piezoelectric vibrator 4 is disposed on the elastic end surface of the cavity 3, and the cavity 3 connects the liquid inlet 1 and the liquid outlet 2 , The vibration of the piezoelectric vibrator 4 controls the expansion and compression of the cavity 3 to complete the liquid inlet and outlet.

[0021] Such as figure 1 As shown, the specific implementation process of the present invention is: the piezoelectric vibrator 4 is bent and deformed under the action of alternating voltage to form a change ...

Abstract

The invention relates to a piezoelectric driving-based infusion pump and a piezoelectric driving-based infusion device. The piezoelectric driving-based infusion pump comprises a liquid inlet, a liquid outlet, a cavity for accommodating liquid, a piezoelectric vibrator, a piezoelectric driving module and a control unit; the piezoelectric vibrator is arranged on the elastic end face of the cavity; the control unit is connected with the piezoelectric driving module; the piezoelectric driving module is connected with the piezoelectric vibrator; the cavity is connected with the liquid inlet and the liquid outlet; the control unit controls the piezoelectric driving module to drive the piezoelectric vibrator to vibrate; and vibration of the piezoelectric vibrator controls extension and compression of the cavity, so that liquid in and liquid out are completed. Infusion is controlled accurately and intelligently by using the piezoelectric vibrator, the piezoelectric driving module and the control unit, so the anti-electromagnetic interference capability of the infusion device is greatly improved, the energy consumption of the infusion device is reduced, and the infusion control accuracy of the infusion device is further improved.

Description

technical field [0001] The invention relates to an infusion pump and an infusion device, in particular to an infusion pump and an infusion device that are easy to control accurately based on piezoelectric drive. Background technique [0002] Infusion pumps have been widely used in clinical treatment, and have been widely used in anesthesia, analgesia, antibiotic treatment, tumor chemotherapy, cardiovascular and cerebrovascular disease treatment, hypertension, and diabetes treatment in China. The application of the infusion pump reduces the treatment risk of the treated patients, reduces the workload of the nursing staff, and greatly reduces the risk of administration of traditional infusion methods during the treatment of seriously ill patients. [0003] The quality and safety of medical devices is the top priority of hospital management, so it is hoped to have a high-performance, intelligent automatic infusion device. The intelligent infusion pump has the incomparable adva...
