Abstract
The utility model provides an automatically exhausting medical intravenous infusion set. The infusion set comprises a liquid inlet component, a dropping funnel, a liquid outlet component and a disposal intravenous injection needle, wherein a precise filter is connected in series on a lower conduit below the dropping funnel; a precise filter membrane which can be passed by liquid rather than air is arranged in the cavity of the precise filter, and separates the cavity of the precise filter into a liquid inlet cavity and a liquid outlet cavity; and the liquid inlet cavity is provided with an exhaust hole and a breathable filter membrane which is arranged in the exhaust hole for exhausting air rather than liquid. According to the medicinal intravenous infusion set, due to a structure that an automatic exhaust component and the precise filter which are combined are integrally arranged on the lateral wall of the dropping funnel, so that the dropping funnel cover is effectively ensured to have the seal performance of an existing common intravenous infusion set, the operation difficulty of medical staff is reduced, the possibility that bubbles exist and are accumulated in the cavity of the dropping funnel is greatly reduced by utilizing the dual-exhaust structure on the automatic exhaust component and the precise filter, air in the dropping funnel can be removed quickly, reliably and completely, and the safety and reliability of infusion is sufficiently ensured.
Description
Technical field
This utility model relates to a kind of medical intravenous infusion set, particularly a kind of can self-bleeding medical intravenous infusion set, belong to medical instruments field.
Background technology
At present, the general infusion set that medical field is commonly used constitutes by parts such as bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, last dropper, dropping funnel, flow regulator, transfusion long duct, liquid medicine filter and disposable use venoclysis needles.When general infusion set had just begun in transfusion, medicinal liquid flowed out from dropper through pipeline, got into dropping funnel; Liquid is prone to that the gas in the dropping funnel is discharged the formation gas-liquid mixture downwards and gets in the long transfusion catheter, therefore produces bubble, simultaneously; Because of the surface tension effects of transfusion catheter inwall, the inwall of transfusion catheter is prone to a spot of bubble of absorption, and it is comparatively difficult, time-consuming and loaded down with trivial details to get rid of consequent bubble process; If the bubble that is produced gets in patient's body, be prone to cause harm such as aeroembolism.So medical personnel must artificial arrange the bubble in the catheter of transfusion system quiet before infusing as much as possible; Common artificial deflated method is: after bottle plug puncture unit is inserted transfusion bottle stopper, with the dropping funnel reversal of the natural order of things, squeeze dropping funnel with hands simultaneously earlier; Medicinal liquid is got in the dropping funnel, treat that certain amount of fluid is full of dropping funnel after, just maybe most bubble be got rid of; The process of this artificial aerofluxus bubble is not only loaded down with trivial details but also time-consuming, is unfavorable for promptly infusing and giving emergency treatment to a patient.To the problems referred to above; Chinese patent CN101337098A and CN101708349A disclose respectively a kind of can self-bleeding intravenous transfusion device; Both cover setting at dropping funnel can stretch into exhaustor or exhaust needle in the dropping funnel and combine with the air filtration film of the not discharge opeing of aerofluxus of device on exhaustor or exhaust needle opening and realize the automatic vent of dropping funnel; Exempt the operating process that loaded down with trivial details time-consuming again artificial aerofluxus is steeped; But these two patent applications are owing to be to cover exhaustor or the exhaust needle that setting can be stretched into the dropping funnel inner chamber at dropping funnel all; Because the dropping funnel cap surface is long-pending limited, covering at the dropping funnel with dropper and liquid injecting piece increases exhaustor or exhaust needle more on the one hand, has both influenced the sealing property and the service life of dropping funnel lid; Make grafting that medical personnel need carry out a plurality of pipelines at narrow and small dropping funnel lid again and be connected, increase its operation easier; On the other hand; The exhaustor or the exhaust needle that stretch in the dropping funnel have many blind spots for effective discharge of bubble in the dropper; The one, adsorb easily on the outer wall on exhaustor or the exhaust needle and have a bubble that is difficult to discharge; The 2nd, also form easily between exhaustor or exhaust needle and the dropping funnel medial wall and gather the bubble that is difficult to discharge, thereby the possibility that causes having bubble in a small amount to get into infusion set influences intravenous security reliability; Especially; Occur easily in the automatic vent assembly of this structure forming the globule that adheres on steam vent (or exhaust needle) and the air-permeative filter film because of the surface tension of liquid effect; Cause covering the situation of this steam vent (or exhaust needle), to the second time and later aerofluxus bringing operational inconvenience and influence its automatic vent function.Again on the one hand, the exhaustor or the exhaust needle that stretch in the dropping funnel can influence the instillation situation that medical personnel observe dropper, and then influences infusion pump dropper is dripped several detection judgements.
Summary of the invention
The purpose of this utility model is to above-mentioned existing problems and deficiency, provide a kind of make simple, easy to operate, aerofluxus more thoroughly, use the self-bleeding medical intravenous infusion set of safety and reliability.
