Medical constant speed transfusion device

Abstract

The invention discloses a medical constant speed transfusion device, which comprises a pushing mechanism, a positioning device, a time controller, a transfusion device and a circuit system. The conventional mode of suspending-bottle transfusion and the conventional administration mode of the elastic retraction of liquid storage bags have the defect of poor accuracy of administration speed. An injector for the conventional micro-transfusion device has small capacity, and needs to be replaced repeatedly under the condition of long-time transfusion, so the continuous transfusion and curative effect are influenced due to transfusion interruption. In the medical constant speed transfusion device, the pushing mechanism is provided with a worm speed reducer, a single-phase controlled rectifying speed regulation circuit is adopted for realizing dual-control speed regulation, a mechanical wriggle device is provided to push the mechanical wriggle device stably at the constant speed to perform the continuous transfusion; the time controller realizes transfusion delay, transfusion intermittence and the programming of delayed transfusion through the regulation of halt and boot-up; and a high-capacity storage injection device is arranged to meet the requirement of one-time transfusion. The medical constant speed transfusion device is convenient to use and economic, relieves nursing workload, improves the life quality and curative effect of patients, and is suitable to be used for one-time transfusion and chemotherapy patients in clinic.

Description

technical field [0001] The invention relates to a medical uniform infusion device. Background technique [0002] The current traditional infusion method is inconvenient to use the height of the hanging bottle, and it is not suitable for patients to infuse for a long time. The infusion tube may fall off, causing pollution and interruption of infusion, increasing medical risks and nursing workload. Uncontrolled backflow device is easy to cause blood return and cause coagulation blockage. Vascular patients are tense and anxious, and the non-intermittent function of drug administration cannot meet clinical needs. The existing liquid storage capsule elastic retraction drug delivery method has the defect of poor drug delivery accuracy, and the existing micro-infusion device matches the syringe with small volume and long length. Time infusion requires repeated replacement of syringes, causing interruption of infusion and affecting continuous infusion and curative effect. It is not ...

[0002] The current traditional infusion method is inconvenient to use the height of the hanging bottle, and it is not suitable for patients to infuse for a long time. The infusion tube may fall off, causing pollution and interruption of infusion, increasing medical risks and nursing workload. Uncontrolled backflow device is easy to cause blood return and cause coagulation blockage. Vascular patients are tense and anxious, and the non-intermittent function of drug administration cannot meet clinical needs. The existing liquid storage capsule elastic retraction drug delivery method has the defect of poor drug delivery accuracy, and the existing micro-infusion device matches the syringe with small volume and long length. Time infusion requires repeated replacement of syringes, causing interruption of infusion and affecting continuous infusion and curative effect. It is not suitable for patients with large injection doses. Chemotherapy drugs for tumor patients need to be administered intravenously multiple times, intermittently, and multiple doses need to be set. Time increases the nursing workload, so the present invention designs an infusion device that integrates propulsion and infusion and can be set at one time to programmatically control continuous and uniform drug delivery, reduce the nursing workload, and meet the clinical needs of patients
