Abstract
The utility model relates to a medical instrument used in clinic for intravenous infusion, particularly to a precision liquid-medicine infusion apparatus with an exhaust valve, which includes a precision liquid-medicine filter. The precision liquid-medicine filter includes an upper casing and a lower casing, a liquid medicine filtration membrane is arranged between the upper casing and the lower casing, and an exhaust membrane is arranged on the lower casing. The medical instrument is characterized in that an exhaust valve is arranged on an exhaust port of the lower casing. When the exhaust valve of the utility model is closed, tissue air enters the lumen and the liquid-dropping phenomenon can be avoided during puncturing.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used for the clinical vein transfusion, is specifically related to a kind of precision filter infusion set with air bleeding valve.
Background technology
Precision infusion set is to give the device of human body by intravenous drip with the medicinal liquid infusion, but the particulate matter in the filtering medicinal liquid in the infusion process.As shown in Figure 1, typical precision filter infusion set is made up of bottle plug puncture unit 1-1, air filter 1-2, dropping funnel 1-3, flow regulator 1-4, injection member 1-5, precision liquid medicine filter 1-6, venoclysis needle 1-7, wherein liquid medicine filter 1-6 is the core component of filtering liquid medicine, and venoclysis needle 1-7 can directly puncture in human vein.As shown in Figure 2, the accurate filter of prior art comprises upper casing 2-1, lower casing 2-2, between upper casing 2-1 and the lower casing 2-2 liquid medicine filtering membrane 2-3 is set, and exhaust membrane 2-4 is set on the lower casing 2-2.
Mainly there is following problem in existing precision filter infusion set:
The operating procedure of precision infusion set is, the bottle plug puncture unit 1-1 medicine bottle that punctures, and medicinal liquid flows down, and utilizes gas in the emptying system of medicinal liquid elder generation, closes flow regulator 1-4 then, just can venipuncture.In this process, the exhaust membrane 2-4 on the liquid medicine filter 1-6 can serve as the effect of gas in the discharge system.Next when carrying out venipuncture, require venoclysis needle can not have fluid drips to fall on the patient skin, otherwise can influence venipuncture, make the venipuncture failure.Medicine liquid droplet is fallen on the patient skin and is commonly called as " dropping liquid " during puncture.
Summary of the invention
This utility model provides a kind of precision filter infusion set with air bleeding valve, increases by an air bleeding valve on liquid medicine filter, to prevent to produce " dropping liquid " phenomenon.
The following technical scheme of the concrete employing of this utility model:
A kind of precision liquid medicine transfusion device with air bleeding valve comprises precision liquid medicine filter, and described precision liquid medicine filter has upper casing, lower casing, be provided with liquid medicine filtering membrane between upper casing and the lower casing, on lower casing, be provided with exhaust membrane, it is characterized in that, on the lower casing air vent, also be provided with air bleeding valve.The agglutinating mode of preferred employing fixedly installs air bleeding valve.
The beneficial effect of this utility model patent is:
Do not have " dropping liquid " phenomenon during venipuncture and produce, be convenient to the nurse and carry out venipuncture.Air bleeding valve on the liquid medicine filter of the present utility model after closing, can stop air and in enter the inner chamber of liquid medicine filter.This moment, though inner chamber liquid can produce the trend that flows downward, because the effect of negative pressure can not flow down, thereby can not produce " dropping liquid " phenomenon.
Description of drawings
Fig. 1 is the structure chart of prior art precision filter infusion set;
Fig. 2 prior art accurate filter structural representation;
Fig. 3 this utility model accurate filter structural representation.
The specific embodiment
Embodiment
As shown in Figure 3, a kind of precision filter infusion set with air bleeding valve, comprise and meet venoclysis needle 3-6 under precision liquid medicine filter, the accurate filter, described precision liquid medicine filter has upper casing 3-1, lower casing 3-2, be provided with liquid medicine filtering membrane 3-3 between upper casing 3-1 and the lower casing 3-2, on lower casing 3-2, be provided with exhaust membrane 3-4, on lower casing 3-2 air vent, also be bonded with air bleeding valve 3-5.
After closing, air bleeding valve 3-5 of the present utility model can prevent " dropping liquid " phenomenon.
Claims (2)
