Embodiment Construction

[0025] Below in conjunction with accompanying drawing, technical scheme of the present invention will be further described:

[0026] The present invention mainly is made of transfusion medicine bottle and transfusion tube 2.

[0027] The infusion medicine bottle is a soft plastic bottle 4, which mainly has two shapes: round and flat, and its nominal volume is 100ml, 250ml, or 500ml. shaped bottle edge 5, as shown in Figure 1 (a) and Figure 1 (b).

[0028] The infusion tube 2 includes a piercer 3 without an air inlet tube at one end and a flow control valve 1 arranged on the tube body.

[0029] The flow control valve 1 includes a valve body 6, a pressure tube wheel 7 and a limit card 8. The tube pressure wheel 7 is slidably arranged in a sliding groove longitudinally provided on the valve body 6, and the limit card 8 is from top to bottom. The bottom is placed in the sliding groove, the inner concave arc at the front end of the limit card 8 is against the rear of the pressure...

Abstract

The invention discloses a flexible plastic high-position negative-pressure infusion apparatus which comprises an infusion medicine bottle hung upside down and an infusion tube with a flow control valve. A puncture device at one end of the infusion tube is inserted into a bottle opening of the infusion medicine bottle, the infusion medicine bottle is a flexible plastic bottle, the flexible plastic bottle is provided with wavy or zigzag bottle edges, a bottle body of the flexible plastic bottle can be axially contracted by the aid of the bottle edges, and the puncture device is free of air inlet tubes; the flow control valve comprises a valve, a tube pressing wheel and a limiting clamp, the tube pressing wheel is slidably arranged in a slide groove formed in the valve, the limiting clamp is arranged in the slide groove, a concave arc opening at the front end of the limiting clamp is abutted to the rear of the tube pressing wheel, and outer teeth on two sides of the limiting clamp are clamped with inner teeth on two sides of the slide groove. The flexible plastic high-position negative-pressure infusion apparatus has the advantages that the flexible plastic high-position negative-pressure infusion apparatus is a fully sealed infusion set, can effectively prevent cross infection, is free of blood return and is safe and reliable in use.

Description

(1) Technical field: [0001] The invention relates to a medical infusion device, in particular to a soft plastic high-position negative pressure infusion device. (2) Background technology: [0002] Intravenous fluids are a common treatment. [0003] The traditional infusion method is to place the infusion medicine bottle at a certain height, and use the gravity drop of the liquid to overcome the venous blood pressure of the human body, so that the medicine liquid enters the human vein through the needle; in order to balance the internal and external pressure difference of the infusion medicine bottle, a infusion tube. [0004] In order to avoid the contamination of the liquid medicine by bacteria, microorganisms and harmful substances in the infusion process (in the air), a sealed infusion device has been designed in the prior art, such as the invention of "A Fully Sealed Infusion Device" with the announcement number CN2194730Y The patent and application number is 200520104...
