Abstract
The utility model discloses a disposable safe liquid medicine filtering infusion apparatus, which comprises bottle stopper puncturing device, an air filter, a dropper, a drop bucket, a flow regulator, an outer cone joint, a disposable intravenous infusion needle and the like. The infusion apparatus is characterized in that a safe liquid medicine filter consisting of a liquid inlet tube, a safe liquid medicine filter shell and a liquid outlet tube is arranged between the drop bucket and the flow regulator; the peripheral sidewall of the liquid inlet tube is provided with a liquid inlet hole; the middle-upper part of the inner wall of the safe liquid medicine filter shell is provided with a supporting disk; a liquid medicine filtering membrane is placed on the supporting disk; and a cylindrical intercepting valve is placed in the safe liquid medicine filter shell. After liquid medicine enters the drop bucket and covers the liquid inlet hole on the sidewall of the liquid inlet tube of the safe liquid medicine filter, air mixed in the liquid medicine can be discharged upwards, so as to effectively prevent bubbles from flowing into the safe liquid medicine filter. The infusion apparatus has the advantages of sealing automatically after infusion is over, preventing the bubbles from entering, having safety and reliability and the like, and can be widely applied to clinic.
Description
Technical field
This utility model relates to aseptic medical equipment, especially relate to a kind of have prevent that bubble from entering the medical filtration transfusion device disposable safe in utilization with automatic sealing function.
Background technology
At present, the general infusion set that medical field is used always is by bottle plug puncture unit, dropping funnel, conduit, flow regulator, parts such as liquid medicine filter and venoclysis needle constitute, when general infusion set enters dropping funnel at medicinal liquid, liquid is discharged the formation gas-liquid mixed downwards with the gas in the dropping funnel and is entered downcomer, produce bubble, medical personnel must get rid of the bubble in the conduit fully and could infuse, and need the nursing staff in the infusion process, patient and family numbers of patients are observed liquid situation in the infusion bottle at any time, in order to avoid when transfusion finishes, cause blood to go back up in a whole set of transfusion organ pipe because of in time not pulling out infusion needle, or liquid level descended low and causes gas to enter human body causing adverse consequencess such as aeroembolism.About existing a lot of the patent design in safe transfusion system aspect, but up to the present, there also do not have a kind of safe transfusion system product to be widely used in to be clinical, and its reason mainly is that its design principle and material selection, manufacturing cost and processing technique aspect exist certain technical difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of can seal automatically after transfusion finishes, prevent that bubble from entering, simple in structure, safe and reliable medical filtration transfusion device disposable safe in utilization.
The purpose of this utility model is achieved in that this utility model comprises the bottle plug puncture unit protective sleeve; bottle plug puncture unit; the transfusion tubulature; the aerofluxus tubulature; air filter; dropper; dropping funnel; flow regulator; the transfusion long duct; outer cone joint and disposable use venoclysis needle; feature is that safe liquid medicine filter is installed between dropping funnel and flow regulator; safe liquid medicine filter is by the feed tube of top and top closure; the drain pipe of intermediary safe liquid medicine filter shell and below is formed; feed tube upwards stretches in the dropping funnel; drain pipe is enclosed within downwards in the feed liquor conduit of flow regulator; on sidewall around the feed tube of safety liquid medicine filter, have the inlet opening that connects the feed tube sidewall; inwall middle and upper part at safety liquid medicine filter shell is equipped with support disk; placement liquid medicine filtering membrane on support disk; on support disk, be processed with the circular hole that allows medicinal liquid flow through, in safety liquid medicine filter shell; the below of support disk is placed with the cylindrical shutoff valve that can block the drain pipe import and have buoyancy.
Sidewall has two or more inlet openings that connects the feed tube sidewalls around the feed tube of safety liquid medicine filter, inlet opening be shaped as a kind of in strip or ellipse or the circle.
This utility model is owing to set up safe liquid medicine filter on the basis of traditional disposable infusion set, so in use, after medicinal liquid enters in the dropping funnel inlet opening on the feed tube sidewall that covers safe liquid medicine filter, the air of sneaking in the medicinal liquid will upwards be discharged, thereby prevents that effectively bubble from flowing in the safe liquid medicine filter.Flow from top to bottom after when medicinal liquid flows into safe liquid medicine filter shell from inlet opening in, flow to below in the safe liquid medicine filter shell by liquid medicine filtering membrane, the medicinal liquid of below can upwards hold up shutoff valve in the safe liquid medicine filter shell, make the shutoff valve come-up, the drain pipe that medicinal liquid can waltz through safe liquid medicine filter enters flow regulator and transfusion long duct, gets final product normal infusion; Liquid is totally lost gradually in infusion bottle, and the medicinal liquid of shutoff valve below can reduce gradually, and shutoff valve also can descend gradually because of action of gravity, and the drain pipe of safe liquid medicine filter sealing is the most at last avoided because of after liquid is totally lost, and air enters human body by the transfusion long duct.This utility model can solve existing transfusion device and waste liquid medicine, shortage safety guarantee, healthcare givers or patient because of aerofluxus bubble and family members' mental burden heavily waits problem in infusion process, thereby effectively reduce medical personnel's working strength, reduce liquid waste, remove the patient and in infusion process, enter the worry that human body causes adverse consequencess such as aeroembolism because of gas.Therefore the utlity model has after transfusion finishes and can seal automatically, prevent that bubble from entering, the advantage of simple in structure, safe and reliable, easy processing, can extensive use clinical.
