Abstract
The invention relates to a transfusion device capable of effectively preventing gas from entering into a pipeline at the beginning of transfusion and in the transfusion process, which belongs to the technical field of disposable medical devices. The transfusion device is characterized in that a hollow variable flow pipe with a closed top end and an opening on the lateral wall is additionally arranged inside an outlet end of a dropping funnel; when a stabber of the transfusion device is inserted in a transfusion bottle or a transfusion bag, the dropping funnel is reversed and extruded to be filled with liquor; when the dropping funnel stands positively, the liquor flowing out from the dropping funnel can not directly impact an outlet at the bottom of the dropping funnel due to the barrier of the top of the variable flow pipe and can flow into the pipeline of the transfusion device from the opening on the lateral surface of the variable flow pipe, so as to achieve the purpose for preventing liquor and gas from entering into the pipeline together.
Description
Affiliated technical field
The present invention relates to a kind ofly in transfusion beginning and infusion process, effectively avoid gas to enter the transfusion device of pipeline, belong to the disposable medical instrument technical field.
Background technology
Conventional transfusion device inserts infusion bottle or transfusion bag by perforator, stand upside down and extruding dropping funnel topping up, when dropping funnel just immediately, because flow stream velocity is very fast, the effusive medicinal liquid in dropper place directly impacts the dropping funnel outlet at bottom, causes medicinal liquid to enter pipeline together with gas, behind the flow speed stability, gas brings potential safety hazard with the form of the bubble tube wall attached to infusion pipeline to transfusion outpatient, also gets rid of bubble to the medical worker and brings inconvenience in the work.
Summary of the invention
For solving the air bubble problem in the conventional transfusion device pipeline, the present invention adopts the unsteady flow pipe that increases top closure, hollow, lateral opening in the inside of the dropping funnel port of export, perforator insertion infusion bottle or transfusion bag when transfusion device, stand upside down and extruding dropping funnel topping up, when dropping funnel just immediately, the effusive medicinal liquid in dropper place is because the obstruction at unsteady flow pipe top is no longer directly impacted the dropping funnel outlet at bottom, and flow into the transfusion device pipeline from the lateral opening part of unsteady flow pipe, reach the purpose of avoiding medicinal liquid to enter pipeline together with gas.
The present invention only needs to increase a unsteady flow pipe at conventional infusion unit titrimeter liquid outlet, product structure is simple, realize easily in the production process, owing to avoided the generation of the interior bubble of transfusion device pipeline in use, this invention had both guaranteed transfusion safety, brought facility in the work for the transfusion operation personnel again.
Description of drawings
Accompanying drawing has provided concrete structure of the present invention.
The specific embodiment
Below, accompanying drawings working condition of the present invention:
The present invention increases a unsteady flow pipe (3) at conventional infusion unit titrimeter liquid outlet, during operation, perforator insertion infusion bottle or transfusion bag when transfusion device, stand upside down and extruding dropping funnel (2) topping up, when dropping funnel (2) just immediately, effusive medicinal liquid located by dropper (1) because the obstruction at unsteady flow pipe (3) top is no longer directly impacted dropping funnel (2) outlet at bottom, and flow into transfusion device pipeline (4) from the lateral opening part of unsteady flow pipe (3), avoided medicinal liquid to impact and entered pipeline together with gas, thereby guaranteed transfusion safety, brought facility in the work for the transfusion operation personnel again.
Claims (2)
1. a transfusion device of effectively avoiding gas to enter pipeline is characterized in that it has unsteady flow pipe (3) in the increase of the inside of conventional infusion unit titrimeter (2) port of export.
2. the transfusion device of effectively avoiding gas to enter pipeline according to claim 1 is characterized in that: unsteady flow pipe (3) top closure, hollow, lateral opening.
