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 has just begun in transfusion, medicinal liquid flows out from dropper by pipeline, enter dropping funnel, liquid is easily discharged the gas in the dropping funnel downwards the formation gas-liquid mixture and is entered 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 a spot of bubble of absorption easily, 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 enters in patient's body, easily cause harm such as aeroembolism.So, medical personnel are before infusing, must manually the bubble in the catheter of transfusion system be arranged as much as possible quiet, common artificial deflated method is: after bottle plug puncture unit is inserted transfusion bottle stopper, earlier dropping funnel is hung upside down, squeeze dropping funnel with hands simultaneously, medicinal liquid is entered in the dropping funnel, treat that certain amount of fluid is full of dropping funnel after, just most bubble may 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.At 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 in the dropping funnel or exhaust needle 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, on the one hand 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 again, the sealing property and the service life of dropping funnel lid had both been influenced, 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, stretch into exhaustor in the dropping funnel or exhaust needle and 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 and gather the bubble that is difficult to discharge between exhaustor or exhaust needle and the dropping funnel medial wall easily, thereby the possibility that causes having bubble in a small amount to enter infusion set influences intravenous security reliability; 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 at above-mentioned existing problems and deficiency, provide a kind of make simple, easy to operate, aerofluxus is more thorough, use the self-bleeding medical intravenous infusion set of safety and reliability.
The technical solution of the utility model is achieved in that
Self-bleeding medical intravenous infusion set described in the utility model, comprise the feed liquor assembly that connects in regular turn, dropping funnel, fluid assembly and disposable vein entry needle, wherein said dropping funnel opening top cover labyrinth is equipped with the dropping funnel lid, and this dropping funnel covers and is provided with the liquid injecting piece that stretches into the dropper in the dropping funnel and be used to add medicinal liquid, described feed liquor assembly is connected with dropper top by the feed liquor tubulature, described fluid assembly is connected by the liquid outlet of fluid tubulature with the dropping funnel below, the disposable vein entry needle is connected with the outlet of fluid assembly, be characterized in being integrally formed with the automatic vent assembly on the described dropping funnel sidewall, this automatic vent assembly comprises and the integrated steam vent of dropping funnel sidewall, but port lid with block of folding, the air-permeative filter film of the not discharge opeing of aerofluxus between port lid and steam vent contact surface.
What wherein, above-mentioned steam vent was positioned at dropping funnel opening below accounts for dropping funnel sidewall total height
On the dropping funnel sidewall of position.
This utility model is owing to adopt the structure that is wholely set the automatic vent assembly at the dropper sidewall dexterously, both can ensure effectively that the dropping funnel lid had the sealing property of original common intravenous injector, and reduction operation of medical workers difficulty, significantly reduce the dropping funnel inner chamber again and had and gathered the probability of bubble, thereby high efficient and reliable the bubble in the dropping funnel is got rid of fully, fully guaranteed the security reliability of transfusion, and this utility model is simple in structure, easy to manufacture, practical.
Below in conjunction with accompanying drawing this utility model is further described.
