Device and method for filling medical infusion bag with hydrogen in non-contact manner

Abstract

The invention relates to a technique of filling an infusion bag with hydrogen and discloses a device for filling a medical infusion bag with hydrogen in a non-contact manner. The device comprises a hydrogen generator (1), a gas and liquid mixer (2), a positive displacement pump (3), a vane pump (4), an open water tank (8), a pressure regulation valve (10), and a sealed water tank (7). By means of the hydrogen generator, the solubility of the hydrogen is improved while any characteristic of water is not changed. The positive displacement pump and the vane pump are used, so the hydrogen is processed into micro-nanometer bubbles, the solubility of the hydrogen in water is greatly improved, and the dissolving time of the hydrogen is shortened. The invention further discloses a method for filling the medical infusion bag with the hydrogen in a non-contact manner. The method comprises the steps of mixing gas and liquid, dissolving the gas under high pressure and releasing the micro-nanometer hydrogen bubbles under low pressure. The solubility of the hydrogen is high, the consumed time is short, the production cost is saved, the purity of the product is improved, the content of impurities is reduced, it is guaranteed that bacteria and heat sources are avoided in the operation process, and accordingly clinical requirements for injection are met.

Description

technical field [0001] The invention relates to a technology for filling hydrogen into an infusion bag, relates to a non-contact hydrogen filling device for a medical transfusion bag, and in particular to a non-contact hydrogen filling method for a medical transfusion bag. Background technique [0002] The hydrogen-containing infusion solution is a medical technology and method first introduced internationally by Professor Sun Xuejun of the Second Military Medical University in 2009. Professor Sun Xuejun has cooperated with more than 40 domestic units, and has carried out research on the treatment of various organ ischemia-reperfusion injury, inflammatory diseases, arteriosclerosis, hypertension, liver injury, diabetes and other diseases with hydrogen saline.

Problems solved by technology

[0003] The method of hydrogen-containing injection. This method obtains hydrogen-containing injection after four steps of degassing treatment, low-temperature pretreatment, injection of pure hydrogen, and pressurization to assist dissolution. However, this method is that hydrogen directly acts and dissolves in the injection Yes, because the clinical requirements for injections are very high, they must be sterile and non-pyrogenic. Improper use of this contact method may cause bacteria to enter, and this method is inefficient and limited in production capacity.

[0004] The Japanese MIZ company has also done the method of using electrolyzed water to produce hydrogen and then injecting hydrogen into the water, filling the infusion bag with hydrogen by soaking. The electrode metal ions fall off and distribute in the water, which will change the characteristics of the water and affect the purity of the water

However, it needs to be soaked for 72 hours, and the hydrogen concentration of the solution in the infusion bag can only reach 1.0PPM
