Problems solved by technology

2. It is easy to make the dripping funnel lose the function of continuously observing the dripping speed
Exhaust will cause the infusion water level in the drip funnel to rise, and the infusion water level will rise to a certain limit so that the drip funnel cannot observe the dripping speed
This will bring inconvenience to the treatment process, and it does not meet the national standards for infusion sets

Embodiment 1

[0023] Such as figure 1 Shown is an automatic exhaust and anti-blood infusion set, the cork piercer 1 is connected to the upper infusion tube 2, and the upper infusion tube 2 is connected to the drip funnel 5. The dripping funnel 5 top is provided with the dripping funnel cover 5B that hard plastics is made. An infusion drop-in tube 3 made of hard plastic is installed on the neck of the drip funnel cover 5B. The bottom of the infusion drip tube 3 is provided with one or more opening holes 3A or opening grooves 3A downwards. An exhaust pipe 4 is arranged in the drip funnel 5, and the central axis of the exhaust pipe 4 coincides with the central axis of the drip funnel 5. The top of the exhaust pipe 4 is located at 1 / 2 to 1 / 3rd of the pipe height of the drip funnel 5. One or more opening holes 4A or opening grooves 4A are formed laterally at the positions between the two. A circular plate 4C is installed on the top of the exhaust pipe 4, and the circular plate 4C is made of p...

Embodiment 2

[0032] Such as figure 2 In the shown automatic exhaust and blood return infusion set, the cork piercer 1 is connected to the upper infusion tube 2, and the upper infusion tube 2 is connected to the dripping funnel 5, and the lower part of the dripping funnel 5 is provided with a dripping funnel support 5A made of hard plastic, On the neck of the dripping funnel 5 upper ends, an infusion dripping tube 3 made of hard plastic is housed, and one or more nozzles 3A made of hard plastic are installed laterally on the transfusion dripping tube 3 . The anti-blood return filter membrane 6 is made of a thickened ordinary liquid medicine filter membrane, which connects with the drip funnel 5 through a ring extending from the drop bucket holder 5A, and the anti-blood return filter membrane 6 is made of ultrasonic or heat-sealed or glued The method makes it fit tightly on the ring body, and there is a gap cavity between the anti-blood return filter membrane 6 and the bottom plate of the d...

Embodiment 3

[0040] Such as image 3 Shown is an automatic exhaust and anti-blood infusion set, the cork piercer 1 is connected to the upper infusion tube 2, and the upper infusion tube 2 is connected to the drip funnel 5. The bottom of the dripping funnel 5 is provided with a dripping funnel holder 5A made of hard plastic. The neck at the upper end of the dropping funnel 5 is equipped with an infusion dripping tube 3 made of hard plastic. The bottom end of the infusion drip tube 3 is sealed, and one or more opening holes 3A or opening grooves 3A are arranged on the side. An exhaust pipe 4 made of hard plastic is provided in the dripping funnel 5, and its central axis coincides with the central axis of the dripping funnel 5. The top of the exhaust pipe 4 is sealed, and the upper side is provided with one or more opening holes 4A or opening grooves 4A. The opening holes 4A or opening grooves 4A are located at one-half to one-third of the pipe height of the dropping funnel between two.

Abstract

The invention discloses an automatic air exhaust and blood return preventing infusion apparatus. The infusion apparatus comprises a bottle stopper puncture outfit, an upper infusion tube, a dripping hopper, a lower infusion tube, a blood return preventing filter membrane, a flow regulator, a hollow sac tube, a liquor filter, an outer conical joint, a fine infusion tube and an intravenous injection needle, wherein the upper end of the dripping hopper is provided with an infusion dripping tube provided with a nozzle or an open hole or a groove; an exhaust tube of which the upper part is provided with an open hole or a groove is arranged in the dripping hopper; the blood return preventing filter membrane is arranged at a position between 2 / 3 of the tube height of the dripping hopper and the lower infusion tube and is prepared from a liquor filter membrane; and the hollow sac tube or the outer conical joint or the liquor filter is provided with a waterproof air filter or waterproof air filter membrane. The dripping hopper can quickly exhaust air, the blood return phenomenon after liquor is completely infused can be avoided, the phenomenon that the air can enter veins once the air enters the lower infusion tube can be avoided, and people can observe the dripping speed of the dripping hopper permanently.

Description

【Technical field】 [0001] The patent of the present invention relates to a disposable medical infusion set, especially suitable for an automatic exhaust and anti-blood infusion set. 【Background technique】 [0002] The current automatic exhaust solution for preventing blood return infusion sets is limited to opening an opening on the wall of the dripping funnel or on the lid of the dripping funnel, and then installing a waterproof air filter membrane or a waterproof air filter membrane and a sealing plug on the opening exhaust device. Although such a design can realize the automatic and very fast exhaust of the dropping funnel, it still has the following defects. 1. The operation is not simple enough. After the dripping funnel wall or the dripping funnel cover of the anti-blood infusion set is equipped with an exhaust device with a waterproof air filter membrane and a sealing plug, when a new infusion bottle is connected, the sealing plug needs to be opened every time when e...
