Abstract

The invention discloses a gravity-resistant infusion structure. The gravity-resistant infusion structure comprises a pressure valve and a connecting tube, wherein the pressure valve has a one-way conduction function and has a conduction critical value, the connecting tube is communicated with the pressure valve, and when the pressure in the tube is larger than the conduction critical value, the pressure valve performs conduction and conducts normal delivery; when the pressure in the tube is smaller than the conduction critical value, the pressure valve is closed, and medicine liquor is prevented from flowing down due to the action of gravity. The pressure valve can effectively prevent the occurrence of the situation that medicine liquor is prevented from flowing down due to the gravity of the medicine liquor, and thus guarantees security in infusion; meanwhile, when a medicine box is in a low position relative to the human body, the pressure valve can effectively prevent the possibility of the occurrence of blood return, and thus the safety in infusion is improved.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an anti-gravity infusion structure and its application method. Background technique [0002] Electronic infusion pumps currently on the market are used for analgesic (including postoperative, painless childbirth, cancer pain treatment, etc.) drug infusion, chemotherapy drug infusion, and emergency drug precision infusion. Infusion rates that are too high or unanticipated overdoses pose serious risks. This type of infusion pump usually consists of two parts, an infusion drive device and a medicine box. Taking analgesic treatment as an example, due to the use of narcotic drugs, the infusion rate is generally small (usually 0.5-5ml per hour), and the infusion rate is too high. Large or unexpected excessive infusion will lead to serious risks. Therefore, the structure of this type of product is designed to prevent gravity infusion. When the infusion drive device and the drug box are assemble...
