The bubble preventive infusion apparatus overcomes the defects that bubbles generated in an infusion catheter in an infusion process of a traditional infusion apparatus enter the body of a patient, and risks are brought to human body life health and life safety, the bubbles can all be discharged by regulating the two flow regulators and the drip chambers no matter where the bubbles appear in the infusion catheter, the bubbles are prevented, and meanwhile efficiency and safety of infusion are improved.
Description
Technical field
This utility model relates to the aseptic medical equipment for the clinical transfusion purposes, relates in particular to a kind of bubble-proof transfusion device.
Background technology
The traditional infusion device is in infusion process, and medicinal liquid flows out from dropper by transfusion catheter, enters dropping funnel, and liquid is easily discharged the gas in the dropping funnel downwards, forms gas-liquid mixture and enters in the transfusion catheter, therefore produces bubble.Simultaneously, because of the surface tension effects of transfusion catheter inwall, the inwall of transfusion catheter is a small amount of bubble of absorption easily.During transfusion, if bubble enters in the patient body, can bring very large potential safety hazard.At present, processing the bubble that enters in the transfusion catheter has dual mode: the one, pull up syringe needle, and again syringe needle is inserted the patient vessel; The 2nd, while twine constantly attack transfusion catheter with finger by rule of thumb by the professional health care personnel, bubble is discharged in the dropping funnel.The weak point of these two kinds of methods is: the former can make the patient again bear affliction; The latter is only applicable to the professional health care personnel, and such operating time is long and loaded down with trivial details, is unfavorable for urgent transfusion and rescue patient, brings great inconvenience for medical worker and patient.
In addition, most medicinal liquids that have more than two bottles in the venous transfusion process if in time do not change medicine bottle, enter air easily in the transfusion catheter, even long section air.Common way is to separate the joining place of infusion needle seat and transfusion catheter, infusion needle seat and transfusion catheter is connected behind the Exhaust Gas again.The drawback of this processing method is: medicinal liquid is contaminated easily, advances easily minute bubbles during linking in the transfusion catheter, if the processing time is long, the transfusion needle inner blood solidifies easily, needs again transfusion needle to be inserted blood vessel, increases the patient suffering.
Bubble-proof transfusion device technical scheme of the prior art is such: at the inner air catcher that increases a multilamellar narrow slit structural shape of the dropping funnel of transfusion device, the air catcher is to adopt transparent medical macromolecular materials production, utilize the bubble surface tension force of liquid-to-air formation by the air catcher, catch the bubble in the liquid, bubble is stoped in dropping funnel and allow liquid flow out.This scheme weak point be, can't discharge the bubble that occurs in the transfusion catheter of the below of dropping funnel in the infusion process.
The utility model content
Enter in the patient body danger that human life health and life security are brought in order to overcome the bubble that produces in the transfusion catheter in the traditional infusion device infusion process, this utility model provides a kind of bubble-proof transfusion device.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of bubble-proof transfusion device, comprise bottle plug puncture unit, described bottle plug puncture unit bottom is communicated with the first dropping funnel and transfusion long duct successively by the transfusion tubulature, described transfusion long duct is provided with the first flow actuator, transfusion long duct between described the first dropping funnel and the described first flow actuator is through with an arm, described arm afterbody communicates with air, be respectively equipped with the second dropping funnel and the second flow regulator on the described arm, described the second dropping funnel is connected with described arm, and described the second flow regulator is positioned at the top of described the second dropping funnel.
As preferably, described arm afterbody is provided with the second air filter.
As preferably, described bottle plug puncture unit side is provided with the aerofluxus tubulature, and aerofluxus tubulature upper end is connected with the first air filter.
As preferably, be communicated with liquid medicine filter and venoclysis needle on the described transfusion long duct.
As preferably, described arm is located at 1/2nd to 2/3rds places of the transfusion catheter between the first dropping funnel and the first flow actuator.
As preferably, described length of tube is 10 centimetres to 30 centimetres.
As preferably, be communicated with dropper between described transfusion tubulature and described the first dropping funnel, described dropper is positioned at described the first dropping funnel, and the length of described dropper is less than the length of described the first dropping funnel, and the length of dropper is 1 to 10 millimeter.
Compared with prior art, the utlity model has following advantage: this utility model adds the second flow regulator and the second dropping funnel on arm and the arm at the traditional infusion device, appear at the first dropping funnel when below when bubble in the infusion process, no longer need to pull up syringe needle syringe needle is reinserted blood vessel, need not to twine transfusion catheter aerofluxus bubble with hands, only need to regulate the second flow regulator and the second dropping funnel on the arm, bubble can be discharged in the second dropping funnel; When bubble appeared at the first dropping funnel top, the first flow actuator on the regulating transfusion long duct allowed medicinal liquid naturally stay, and bubble can be discharged in the first dropping funnel.Therefore, no matter bubble appears at any position of transfusion catheter, can bubble be discharged by regulating two flow regulators and dropping funnel, has improved efficient and the safety of transfusion in the time of Anti-bubble; Overcome the bubble that produces in the transfusion catheter in the traditional infusion device infusion process and entered in the patient body danger that human life health and life security are brought; Simplified the operating procedure of aerofluxus bubble, do not needed nurse's Whole-Process Company During Labor in patient's infusion process, family numbers of patients can be finished the operation of aerofluxus bubble; Simple, safe and reliable, the easy processing of product structure can be widely used in clinical.
