Embodiment 1

[0014] Embodiment 1: a kind of system of changing infusion medicine bottle continuously automatically, as Figure 1-3 As shown, it includes a turntable 9, a hollow double-layer bottle, a needle device 10, a liquid drop monitoring system, and a controller. There are multiple hollow double-layer bottles, and each hollow double-layer bottle has an inner cavity for holding an infusion medicine bottle. The chamber is fixed and distributed on the circumference of the turntable 9 in such a way that the mouth of the bottle matches downwards. The center of the turntable 9 is connected to the rotating part of the steering gear, and the fixed part of the steering gear is connected to the support column below it. The needle tube device 10 includes a needle And the needle vertical adjustment device, the needle tube device 10 is installed on the support column, the needle is located below a stop position, the stop position is that the steering gear drives the turntable 9 to rotate and makes ...

Embodiment 2

[0054] This invention is an invention created by many teachers and students of Dalian University for Nationalities and Dalian University. It participates in the research and development of different technical topics. The system involved is to detect the liquid in the infusion bottle through the pressure strain gauge to detect whether a bottle has clear medicine Liquid, which monitors the remaining liquid in the infusion bottle with quality (corresponding to gravity, weight), so as to choose whether to change the bottle or end the infusion. Realize the intelligentization of infusion control.

[0055] In the case of unsupervised patients, and when nurses encounter emergency situations, they are too busy to monitor patients, causing many people to be impatient when changing infusion bottles and pulling out needles, which has caused certain losses to the hospital and patients. .

[0056] The concept of this work is to help nurses to monitor patients when they are busy. The work ...

Embodiment 3

[0120] For one infusion, it is necessary to input multiple bottles of medicinal liquid sequentially, which will lead to the need to pay more attention to the remaining amount of medicinal liquid during the infusion process, and special medical personnel are required to check the infusion bottle after a bottle of infusion is finished. Replacement, human care and service costs are more obvious.

[0121] In order to solve the above problems, the present invention proposes the following technical proposal: a system for continuously and automatically changing transfusion medicine bottles, including a turntable, a hollow double-layer bottle, a needle device, a drip monitoring system, and a controller. There are multiple layers of bottles, and each hollow double-layer bottle has an inner cavity to accommodate the infusion bottle, which is fixed and distributed on the circumference of the turntable with the mouth of the bottle facing downward. The center of the turntable is connected t...

Abstract

A needle tube device belongs to the medical care field, and can move up and down to complete the function of inserting and withdrawing a needle. One side of a fixing block is fixedly connected with one end of a horizontal rod, the other end of the horizontal rod is fixedly connected with the bottom end of a vertical rod, the fixing block, the vertical rod and the horizontal rod are fastened in a groove arranged in a support column in order to fix the needle tube device, the bottom surface of the fixing block is penetrated, the bottom end of a screw is limited in a through hole, the end surfaceof the bottom end of the screw is connected with a rotary motor, the screw rotates with the rotary motor and is fixed by the fixing block, the screw is in threaded connection with one end of a transverse needle rod, and the end is a nut end. The needle tube device can move up and down to complete the function of inserting and withdrawing the needle, and realizes automatic control and monitoring of the needle insertion and withdrawing in the process of automatic medicine changing of an infusion bottle.

Description

technical field [0001] The invention belongs to the field of medical care and relates to a needle tube device. Background technique [0002] The emergence of intelligent medical care provides information exchange functions for people's lives, optimizes people's lifestyles, and more importantly, enhances the safety of medical care and enhances more caring and humanistic features. Contents of the invention [0003] In order to solve the problem that the needle tube device can cooperate with the up and down movement to complete the insertion and withdrawal of the needle, the automatic dressing change can be realized by cooperating with the rotation. The present invention proposes the following technical scheme: the needle tube device includes a vertical screw, a fixed block, a rotating motor, a horizontal bar, a horizontal needle bar, and a vertical bar. One side of the fixed block is fixedly connected to one end of the horizontal bar, and the other end of the horizontal bar ...
