Problems solved by technology

The intravenous infusion tube of this structure must pay attention to the height of the liquid level in the liquid level display tube when using it. When the end is approaching, it is also determined whether to terminate the infusion through the display of the liquid level display tube. If you do not pay attention, blood will appear.

Embodiment approach

[0016] In one embodiment, the strain gauge 4 is an aluminum foil or a light-weight stainless steel sheet.

[0017] In another embodiment, the strain gauge 4 is made of carbonaceous material. Considering that the infusion is an alkaline or acidic liquid, which is inevitably corrosive to metals, a preferred embodiment is to use a carbonaceous material with high stability. The material is made into strain gauge 4 .

[0018] Preferably, the strain gauge 4 is in a "Γ" shape.

[0019] Preferably, the angle between the strain gauge and the horizontal plane is 45°˜60°.

[0020] Preferably, the material of the joint 6 is a zinc-copper alloy.

[0021] Preferably, the microcomputer alarm 7 is provided with light-emitting diodes and buzzers.

Abstract

The invention discloses a vein infusion tube, and belongs to the field of medical instruments and apparatuses. The vein infusion tube comprises an infusion tube body. A liquid level display tube is communicated with the middle of the infusion tube body. A stretching-out strain gauge is arranged on the inner side of the tube wall of the liquid level display tube. A pressure sensing element is arranged between the strain gauge and the tube wall. The pressure sensing element penetrates through the tube wall, and the outer side of the tube wall is provided with a joint, and the joint is electrically connected with a microcomputer type alarm; the vein infusion tube has the advantages that due to the fact that the sensing element is arranged on the outer side of the liquid level display tube, when the liquid level is lowered to the certain degree, the pressure sensing element can give an alarm through the alarm, a patient is reminded to ask a medical worker to stop infusion, no special attention needs to be paid during infusion, and convenience is provided for a nurse and the patient in rest; meanwhile, the carbon strain gauge is adopted, so that the vein infusion tube is high in stability, safe and reliable.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intravenous infusion tube. Background technique [0002] The existing intravenous infusion tube includes an infusion tube body, a liquid level display tube is connected in the middle of the infusion tube body, the infusion tube body located above the liquid level display tube drips liquid into the liquid level display tube, and there is a certain amount of liquid in the liquid level display tube. The liquid is then injected into the body through the infusion tube body below the liquid level display tube. The liquid input can be observed through the liquid level display tube. When using the intravenous infusion tube of this structure, you must pay attention to the height of the liquid level in the liquid level display tube. When the end is approaching, it is also determined whether to terminate the infusion through the display of the liquid level display tube. If you are not car...
