Abstract
The utility model relates to a medicine supplying pump which belongs to a clinical therapeutic tool, mainly comprises a pump body and an output tube, wherein, the pump body is provided with a medicine storage chamber; the inner wall of the bottom part of the pump body is provided with a metal bottom plate for preventing a needle head from thrusting through the pump body into subcutaneous tissue when injecting medicine liquid; a one-way valve structure is arranged in the output tube, rear ends of two valve leaflets of the one-way valve are connected with the inner wall of the output tube, and the reducing front end is supported by an elastic body which is connected with the inner wall of the output tube. The utility model solves the problems existing in present medicine feeding pumps that medicine liquid and blood flows back to the pump body, and medicine liquid is injected into subcutaneous tissue.
Description
This utility model belongs to the clinical treatment apparatus, mainly proposes a kind of Medicine supplying pump.
Chemicals feed pump is imbedded at subcutaneous tissue in clinical, can be used for the hepatic artery catheterization dispensing, intraperitoneal chemotherapy dispensing etc., and pump housing outlet tube can link to each other with Hepatic artery or abdominal cavity, makes the medicinal liquid in the chemicals feed pump directly enter Hepatic artery, abdominal cavity.Be used for clinical Medicine supplying pump now, it is output as worn-out open channel does not have control structure, when hepatic artery catheterization, the Hepatic artery blood back flow often occurs and goes into pump chamber, and blood solidifies in pump chamber, uses thereby make tube chamber block influence; Be flexible structure around its pump in addition, syringe needle easily pierces through the pump housing when puncture injection, makes medicinal liquid be injected into subcutaneous tissue, causes overflow of drug fluid, necrosis of subcutaneous tissue.
The purpose of this utility model promptly is to propose a kind of Medicine supplying pump that improves structure, overcomes the problem that exists in the existing chemicals feed pump use.
This utility model is finished the technical measures that its invention task takes: mainly include the pump housing and outlet tube, in the pump housing of being made by nontoxic silica gel the drug storage chamber is arranged, the inwall of pump housing bottom is provided with a metal caul; The needle pierces pump housing when preventing liquid medicine injection.The two lobe leaf rear ends that one unidirectional flap valve structure one-way flap valve is set in outlet tube are connected on the outlet tube inwall, are supported by the elastomer that is connected on the outlet tube inwall behind the front end convergent; To Hepatic artery, when flow in the abdominal cavity, flap valve leaf front end opens medicinal liquid by pump housing drug storage chamber thus, elastomer contracts, and injection finishes, and flap valve leaf front end is automatic pinch confinement under the elastomer effect, prevents that medicinal liquid, blood from refluxing.
The chemicals feed pump that the utility model proposes improves structure, and syringe needle easily pierces through pump housing injecting liquid drug and goes into hypodermic problem in the time of can solving prior art herb liquid, blood preferably and easily pass back into pump chamber and injection, and has characteristics simple in structure, easy to implement.
Embodiment:
Accompanying drawing 1 is this utility model structural representation.
In conjunction with the accompanying drawings its structure is further specified:
As shown in drawings: it mainly includes the pump housing 1 and outlet tube 2, the pump housing is made by nontoxic silica gel, drug storage chamber 3 is arranged in the pump housing, above agent structure is identical with existing chemicals feed pump, the inwall of pump housing bottom is provided with a metal caul 4, and a unidirectional flap valve structure is set in outlet tube, and two lobe leaves, 5 rear ends of unidirectional flap valve are connected on the outlet tube inwall, support by the elastomer 6 that is connected on the outlet tube inwall behind its front end convergent, medicinal liquid, blood can not be refluxed.
