Automatic recovery device of medical infusion apparatus

Abstract

The invention discloses an automatic recovery device of medical infusion apparatus. A magnet layer comprises magnetic conduction blocks and electromagnets, and each magnetic conduction block corresponds to one set of electromagnet, and the electromagnets are electrified to generate magnetism; through conduction, the corresponding magnetic conduction blocks also have magnetism due to the fact thatiron cores of the electromagnets are attached to the bottom surfaces of the corresponding magnetic conduction blocks, needle heads are attracted to adjacent positive pole pieces and negative pole pieces, and then the positive pole pieces and the negative pole pieces are conducted; the needle heads are heated after being electrified, and under the centrifugal action of needle tubes, the heated needle heads and the needle tubes are separated; the separated needle heads are subjected to action by the magnetic conduction blocks, so that the needle heads are not prone to be separated from a ceramiclayer corresponding to the magnetic conduction blocks during subsequent separation; according to the device, one magnetic conduction block corresponds with one end of a coil of the electromagnets andis connected with the positive pole of a power supply through thermistors, and the positive pole pieces arranged on the ceramic layer corresponding to the magnetic conduction blocks are also connected with the positive pole of the power supply through the same thermistors; and when the needle heads are attracted on the ceramic layer corresponding to the magnetic conduction blocks, the needle heads are heated, the heated needle heads are separated from the needle tubes under the centrifugal action of the needle tubes.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic recovery device for a medical infusion set, in particular to the safe recovery of a disposable infusion set. Background technique [0002] Disposable infusion set is a common medical consumable. After aseptic treatment, a channel between vein and medicinal liquid is established for intravenous infusion. Generally, it is composed of eight parts such as venous needle or injection needle, needle cap, infusion hose, liquid medicine filter, flow rate regulator, drip pot, cork puncturer, air filter, etc. Some infusion sets also have injection parts , dosing port, etc. In order to prevent infusion sets from being used for secondary use in the society, medical institutions basically recycle all used infusion sets for centralized treatment. However, after collection and recovery, the residual liquid medicine in the infusion set often flows on the ground, causing pol...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art. The purpose is to provide an automatic recovery device for medical infusion sets, which solves the problem that the residual medicinal liquid often flows and causes pollution during the recovery process of disposable infusion sets. The needles are easy to cause the risk of stabbing injuries to the recyclers. In addition, the needles are manually cut off for collection, and there is still a section of the infusion tube on the needle, which causes the subsequent needles to be recycled and disposed of separately, and this section of the infusion tube needs to be collected again Removal, time-consuming and labor-intensive, causing the problem of increased recycling costs
