Problems solved by technology

Its structure is complex, the amount of medicine injected is not stable and accurate, and skilled technology is required for maintenance; after the medicine liquid is injected, the residual amount of medicine liquid in the medicine bag is large, the waste is serious, and the product price is relatively expensive
In the medicine bag, the inflow and outflow of the medicine solution are switched at the same position of the casing, so it is not possible to continuously inject the medicine solution into the patient's body while replenishing the medicine solution at the same time

Embodiment Construction

[0020] From figure 1 , figure 2 It can be seen from the figure that a precision analgesic infusion set of the present invention is provided with an injection needle joint 1, a filter 2, a clamp 3, a drip funnel 4, a catheter 5, a flow regulator 6, a protective shell 9, an elastic storage The medicine capsule 10 and the elastic medicine storage capsule 10 are located in the protective shell 9 . The protective shell 9 plays the role of protecting the capsule from being squeezed and scratched, preventing the medicine liquid from being splashed on the patient after the medicine storage capsule is broken. Under the action of the contraction force of the elastic medicine storage capsule 10, the medicine liquid stored in the elastic medicine storage capsule is output through the catheter and injected into the patient's body. The filter 2 is used to filter the liquid medicine; the clamp 3 is engaged outside the catheter to open or stop the circulation of the liquid medicine in the ...

Abstract

A precise transfusion apparatus for antalgic purpose is composed of a protective casing with a three-way supporter in it, an elastic medicine bag, flow regulator, dripping hopper, guide tube, filter, needle jointer and needle. Its advantages are simple structure, uniform transfusion speed, and high antalgic effect.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a precision analgesic infusion set. Background technique [0002] As we all know, in the clinical treatment of postoperative pain, advanced cancer pain and various intractable pain, intravenous injection of anesthesia and analgesics is a commonly used method, which can effectively relieve the patient's pain and make the patient comfortable and happy. Improve the sense of security. At present, methods such as continuous trace drug analgesia and patient-controlled drug analgesia are mostly used at home and abroad. The flow rate is mostly controlled by a restrictor placed in the pipeline. The continuous drug injection uses an elastic material (silica gel) drug capsule, which relies on the contraction force of the expanding capsule itself to compress the drug solution as a power source, and its effect on the drug solution The driving pressure is basically a quasi-constant pressure. For examp...
