Description
Technical field
This utility model relates to a kind of supply formula infusion set.
Background technology
Existing infusion set is a simple syringe mostly, by the syringe needle on syringe, medicinal liquid is inputted in patient body, but in injection process, cannot supplement by the medicament of liquid dose to syringe inside needed for patient, therefore duplicate injection is on the skin of the patient needed, add the pain of patient, therefore comparatively impracticable.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of supply formula infusion set, this device can supplement the liquid dose of needle tubing inside in the process of injection, avoid repeating acupuncture treatment to patient, reduce patient suffering, bring conveniently to medical personnel simultaneously.
For solving the problem, this utility model adopts following technical scheme:
A kind of supply formula infusion set, comprise needle tubing, and be arranged on the syringe needle of needle tubing front end, and be arranged on needle tubing inside, and extend to the piston of syringe rear end outside, described needle tubing outer wall is provided with a projection near needle position place, described projection has tip, described tip is communicated with the inwall of described needle tubing, described protruding external screw-thread is connected with a medicinal liquid and supplements bottle, sealer is provided with inside the bottleneck that described medicinal liquid supplements bottle, described medicinal liquid supplements bottle backspin when going to extreme position, the tip of described projection punctures described sealer, described piston has an inclination angle near one end of described syringe needle, described needle interior wall is provided with the inclination angle of an equal angular near needle position place, described projection is relative with the incident angle place of needle interior wall.
As preferred technical scheme, described piston is connected with a piston rod, and the one side that described piston rod deviates from described piston is provided with press section.
As preferred technical scheme, described piston rod is cross.
As preferred technical scheme, the rear end of described needle tubing is provided with an oval force sheet.
As preferred technical scheme, the air pressure that described medicinal liquid supplements bottle inside is greater than atmospheric pressure.
The beneficial effects of the utility model are: supplement bottle by set medicinal liquid, when the liquid dose of needle tubing inside is inadequate, can supplement liquid dose, avoid to patient repeat acupuncture treatment, reduce patient suffering, bring conveniently to medical personnel, the structure of this device is comparatively simple simultaneously simultaneously, cost is comparatively cheap, is applicable to promoting the use of.
