An automatic infusion bottle changing device

Abstract

An infusion automatic bottle changing device belongs to the technical field of medical devices. The mounting bracket (14) is installed on the side of the inner gear (5) of the planetary gear train (6), and moves synchronously with the inner gear (5), and the puncture needle (3) can be mounted on the mounting bracket (14) in a liftable manner , the puncture needle (3) is connected with the planet carrier (15) of the planetary gear train (6) through the transmission mechanism, and rises and falls with the rotation of the planetary carrier (15). A lift lock is provided between the transmission mechanism and the planetary carrier (15). There is a locking mechanism (18), the inner gear (5) is connected with a rotation locking mechanism (19), and the power device is connected with the sun gear (17) and drives it to rotate. The automatic infusion bottle changing device has fast bottle changing speed, convenient and precise control of the position of the puncture needle, can ensure the alignment of the puncture needle and the infusion bottle, and ensure stable operation of the equipment.

Problems solved by technology

[0002] my country is a country with a large population, and the development of medical care is an important guarantee for the development of a country. However, most of the traditional infusion methods use manual bottle changing. The process of changing bottles is simple and highly repeatable.

[0003] The Chinese utility model patent with the application number 201620901644.2 discloses an automatic infusion needle changing device for medical care, which drives the needle up and down through a needle motor, and realizes the rotation of the infusion bottle through a stepping motor to realize automatic bottle change. Driven by two motors, there are the following problems: 1) The bottle change action is realized by two motors. In order to avoid the mutual interference of the two motors, after the conveying bottle is rotated in place, it needs to wait for a certain period of time before the needle can move, and the bottle change is completed. , resulting in slow bottle change; 2) The stepping motor drives the infusion bottle to rotate. Due to the heavy weight and high inertia of the infusion bottle, it is difficult to stop the infusion bottle immediately when the infusion bottle is delivered, which makes it difficult to align the needle with the infusion bottle. The work is very unstable; 3) In order to realize the precise control of the needle and the infusion bottle, two servo motors or stepping motors are required, resulting in high equipment costs
