Abstract
The invention provides medical apparatus and instruments, and in particular provides a device for preventing liquid medicine from reversely flowing during feeding liquid medicine into a liquid storing container in a medical apparatus. The invention aims to provide a medicine feeding device for preventing liquid medicine from reversely flowing during feeding medicine. The medicine feeding device comprises a T-shaped pedestal, wherein holes on the pedestal are three intercommunicated through holes; a medicine feeding cylinder body is vertical to cylinder bodies of other two through holes; a liquid resisting body is arranged on the medicine feeding cylinder body; the liquid resisting body is made of an elastic material, and is a hollow body with one end sealed; and the hollow body is formed by clinging at least two sheets; and the opening end of the liquid resisting block is fixed in the medicine feeding cylinder body, and separates an internal chamber of the medicine feeding cylinder body into two sections. The medicine feeding device has the characteristics of convenience in use, simplicity in operation, and low cost.
Description
Technical field
What the present invention relates to is a kind of medical device, especially gives the device of the anti-stream of anti-medicinal liquid when liquid storage container adds medicinal liquid in the medical apparatus and instruments.
Background technology
Present disposable infusion device or infusion device, like high pressure injector, disposable infusion pump etc. are stress-free before use; During use, because this infusion set is to be in sealing state, pipeline is provided with chemicals dosing plant; Medicinal liquid adds in it through chemicals dosing plant, and its inner meeting produces pressure, when amount of liquid medicine increases; Pressure can increase, and medicinal liquid can flow out to the outside from dosing mouth, makes dosing fail.
Summary of the invention
The chemicals dosing plant of the anti-stream of the anti-medicinal liquid that medicinal liquid can instead not flow when the objective of the invention is for the deficiency that solves above-mentioned technology a kind of dosing to be provided.
In order to achieve the above object; The chemicals dosing plant of the anti-stream of a kind of anti-medicinal liquid that the present invention designed; It comprises and is T type base, the through hole of the intercommunication of the Kong Weisan on the described base, and described band dosing cylinder is perpendicular to the cylinder of other two through holes; Described dosing cylinder is provided with bluff body; Described bluff body is elastomeric material and is at least two ducted bodies that fit tightly the sealing of formation one end that described bluff body opening is fixed on the dosing column body, is separated into two sections to the dosing cylinder intracavity.
It can be that the bluff body opening has outward extending edge that described bluff body opening is fixed on the fixing of dosing column body; The dosing cylinder has boss; The edge of bluff body contacts with boss; Contact for last half of the another side at bluff body edge and the dosing cylinder that matches, thereby realize the fixing of bluff body; Certainly, described bluff body opening can be to be bonded on the inwall of dosing cylinder, also can be welding.
It is best that described bluff body fits tightly the ducted body that constitutes end sealing by two, and sealing end shape can be duckbilled body, conically shaped body, sphenoid, prismatoid etc.; The profile of bluff body is a cylinder, and the one of which end is made symmetric inclined-plane, both sides, opens an edge of a knife seam at the top on inclined-plane, this no gap of edge of a knife seam.
The material of the chemicals dosing plant of the anti-stream of anti-medicinal liquid is a kind of in rubber, silica gel, the thermoplastic.
During dosing, medicinal liquid injects from dosing mouth, and the bluff body joint place receives medicinal liquid pressure and opens, and medicinal liquid passes through the orifice flow of base in liquid storage container; After adding the medicinal liquid completion, the bluff body of being made by elastomeric material returns to sealing state, although the cavity internal pressure of bluff body lower end increases, medicinal liquid can not instead flow out filling opening.Thereby, characteristics such as the chemicals dosing plant of the anti-stream of anti-medicinal liquid of the present invention has easy to use, simple to operate, and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Combine accompanying drawing that the present invention is done further description through embodiment below.
Embodiment 1:
In Fig. 1, the chemicals dosing plant of the anti-stream of anti-medicinal liquid of the present invention, it comprises and is T type base 1; The through hole of Kong Weisan intercommunication on the described base 1; Described dosing cylinder 2 is perpendicular to the cylinder 3,4 of other two through holes, and described dosing cylinder 2 is provided with bluff body 5, and described bluff body 5 is elastomeric material and is two ducted bodies that fit tightly the sealing of formation one end; Described bluff body 5 openings are fixed on dosing cylinder 2 inside, are separated into two sections to dosing cylinder 2 inner chambers; The profile of described bluff body 5 is a cylinder, and the one of which end is made symmetric inclined-plane, both sides, opens an edge of a knife seam at the top on inclined-plane, this no gap of edge of a knife seam; Its material is a thermoplastic elastomer (TPE).
