Abstract
The utility model relates to a continuous-injecting device, which is composed of a pressure pump, a middle pipe passage and an injecting needle. The middle pipe passage is composed of a pin 2, a core control membrane filter 3, a middle pipeline 13, a middle pipeline 4, a screwed nipple 5, a screwed nipple 7 and a current regulator 6. The utility model has the advantages of simple structure and adjustable flow, and is especially suitable for the chronic pain therapy and the required continuous-injecting occasion of the patients of after operated and cancer.
Description
This utility model is a kind of improved lasting infusion appliance, and it belongs to medical instruments field.
At present, external existing trace continues infusion appliance, and its flow is by placing the steel pipe reducer on the pipeline to control, and by the fabric filter on the pipeline medicinal liquid is filtered.But the shortcoming of this lasting infusion appliance is that flow is little and single, according to treatment various disease needs flow difference, therefore requires flow adjustable in clinical practice; In addition, the about 0.24mm of steel pipe reducer internal diameter, length is 1m nearly, and technology is very complicated, and inner-walls of duct cleans very difficult.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of low price, technology is simple, flow is adjustable novel lasting infusion appliance are provided.
In order to achieve the above object, this utility model now elaborates by the following technical solutions in conjunction with the accompanying drawings:
Fig. 1 is the structural representation that continues infusion appliance.
Fig. 2 is the structural representation of flow controller.
As shown in Figure 1, the utility model is made up of compression pump, intermediate duct part and injection needle three parts, with ordinary syringe soup is injected compression pump 12, rubber bile duct 1 in the pump expands, make it to produce elastic contractile force, make the soup intermediate duct of flowing through partly enter injection needle and enter then human body. Intermediate duct partly comprises, contact pin 2, nuclear control film filter 3, pipeline 4 and 13, nipple 5,7 and flow controller 6. Contact pin 2 one ends link to each other with the pump housing, and the other end and pipeline 4 join, and nuclear control film filter 3 places pipeline 4, and flow controller 6 two ends are connected with being connected with pipeline 4 respectively by nipple 5, and pipeline 13 other ends join with nipple 7 and injection needle 8. The internal diameter of flow controller adopts the special process manufacturing, only has tens microns, material selection medical plastic pipe or steel pipe, and its length reduces to about 20mm, designs simplification not only, and clean very convenient.
As shown in Figure 2, the structure of flow controller is, the flow controller of two different sizes is encapsulated in the housing, and two ends are connected with threeway 9 respectively, and two flow controllers 6 are controlled by switch 10 and 11 respectively, can realize like this adjusting of three kinds of flows.
In medical procedure, because the different state of an illness needs different injection flows, can turn on nipple 5, realize by reducer or the flow controller of changing different size.
This utility model is simple in structure, and is cheap, safe and reliable, and flow is adjustable, applied widely, and it is convenient to clean, and has obviously strengthened therapeutic effect.
