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] At present, the traditional infusion method is inconvenient to use the height of the hanging bottle for infusion, 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, which increases the medical risk and nursing workload. Without a controlled backflow device, it is easy to cause blood return and cause coagulation to block blood vessels. , causing tension and anxiety in patients, and the non-intermittent function of drug administration cannot meet clinical needs. The existing elastic retraction drug delivery method of the liquid storage bag has the defect of poor drug delivery speed accuracy, and the matching syringe of the existing micro-infusion device has a small capacity. , long-term infusion requires repeated replacement of the syringe, resulting in interruption of infusi...

[0002] At present, the traditional infusion method is inconvenient to use the height of the hanging bottle for infusion, 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, which increases the medical risk and nursing workload. Without a controlled backflow device, it is easy to cause blood return and cause coagulation to block blood vessels. , causing tension and anxiety in patients, and the non-intermittent function of drug administration cannot meet clinical needs. The existing elastic retraction drug delivery method of the liquid storage bag has the defect of poor drug delivery speed accuracy, and the matching syringe of the existing micro-infusion device has a small capacity. , long-term infusion requires repeated replacement of the syringe, resulting in 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 continuously intravenously for many times, and intermittently, and multiple settings are required. The administration time increases the nursing workload. For this reason, the present invention designs an infusion device that integrates propulsion and infusion, which can be set at one time and can be programmed to control continuous and uniform drug delivery, so as to reduce the nursing workload and meet the clinical needs of patients.
