Embodiment 1

[0039] Embodiment one: infusion tube air bubble removal device, such as Figure 1-2 As shown, the bubble removal chamber 2 is included, and the lower end of the bubble removal chamber 2 is connected with a liquid inlet channel 1 and a liquid outlet channel 3. The liquid inlet channel 1 is arranged at a corner. Preferably, the liquid inlet channel 1 is arranged at a right angle, and the liquid inlet channel 1 is arranged at a right angle. The beginning of the channel 1 is connected to the upper infusion tube 7, the beginning of the liquid inlet channel 1 is arranged perpendicular to the installation direction of the air removal chamber 2, and the terminal of the liquid inlet passage 1 is arranged upward along the installation direction of the air removal chamber 2; 3 can be arranged in a corner or in a straight line, regardless of whether the liquid outlet channel 3 is arranged in a corner or in a straight line, but the terminal of the liquid outlet channel 3 is arranged downwar...

Embodiment 2

[0042] Embodiment two: infusion tube air bubble removal device, such as image 3 As shown, the difference between Embodiment 2 and Embodiment 1 is that the lower end of the debubble chamber 2 is detachably connected with a connecting seat 4 for connecting the liquid inlet channel 1 and the liquid outlet channel 3, and the debubble chamber 2 and the fixing part are integrated Molded setting, the connecting seat 4 and the liquid inlet channel 1 and the liquid outlet channel 3 are integrally formed and set.

[0043] The connecting seat 4 includes a connecting ring 41 and a connecting bottom wall 42. The connecting ring 41 is socketed with the air-removing chamber 2, wherein the connecting ring 41 is socketed at the lower end of the air-removing chamber 2, or the lower end of the air-removing chamber 2 is sleeved. Connected to the connecting ring 41, the selection of any of the above-mentioned technical solutions in the present invention has no effect on the realization of the pur...

Embodiment 3

[0046] Embodiment three: infusion tube debubble device, such as Figure 4-5 As shown, the difference between the third embodiment and the second embodiment is that the upper end of the debubbling chamber 2 is provided with an injection hole 21 communicating with the outside world, and the inner wall of the injection hole 21 is provided with a card slot 211, and a card slot 211 is installed in the card slot 211. The adapted flexible injection part 6 is engaged with the slot 211, wherein the flexible injection part 6 can be made of soft elastic materials such as rubber.

[0047] In the specific implementation process of the third embodiment, the infusion tube de-bubble device needs to be turned upside down to fill the de-bubble chamber 2 with liquid medicine, and the bubbles flow through the upper infusion tube 7 and the liquid inlet channel 1 and then float up to the de-bubble chamber 2 However, the medicinal liquid continues to flow through the liquid outlet channel 3 and ente...

Abstract

The invention relates to an air bubble removing device for an infusion tube. The air bubble removing device of the infusion tube comprises an air bubble removing chamber, wherein the lower end of theair bubble removing chamber is connected with a liquid inlet channel connected with an upper infusion tube and a liquid outlet channel connected with a lower infusion tube; the liquid inlet channel isarranged as a corner; the orientation of the tail end of the liquid inlet channel is opposite to the orientation of the tail end of the liquid outlet channel; and a fixing piece for maintaining the air bubble removing chamber to be always arranged in the direction of the infusion tube is arranged on the outer wall of the air bubble removing chamber. The invention further relates to an infusion device which comprises a bottle stopper puncture device, an air filter, the upper infusion tube, the lower infusion tube, a flow adjuster, a medicine filter and an intravenous infusion needle, and further comprises the air bubble removing device for the infusion tube. The air bubble removing device for the infusion tube has the advantages that air bubbles are removed in a continuous infusion process.

Description

technical field [0001] The invention relates to the technical field of aseptic medical instruments, in particular to an air-removing device for an infusion tube and an infusion set. Background technique [0002] Intravenous infusion is one of the most clinically used nursing activities. It is a small problem in the whole medical process. If it is ignored, it will bring unnecessary pain to patients. In clinical practice, when patients undergo infusion therapy, air bubbles often appear in the infusion tube. There are many reasons for the air bubbles, such as: environmental temperature difference, drug properties, pipeline defects, improper operation, etc. If air bubbles enter the patient's venous blood vessels through the infusion tube, it may cause air blockage and endanger life, so air is strictly prohibited from entering the vein from the intravenous infusion route. [0003] With the extensive use of infusion tubes and other products in clinical practice, the problem of ai...
