Abstract
A portable gas-producing pressurization device for transfusion comprises a gear box (4), an inner case (5), an outer case (17), a drug sac tape (9), shaft needles (18), internal and external gas-guiding tubes (10), and a buffer case (14). The gear box and a gear shaft (12) are connected in the apparatus. And the drug sac tape is linked to the gear shaft by a shaft slot. Cylindrical drug sacs (8) filled with drug granules (30) are distributed evenly on the drug sac tape. The internal gas-guiding tube is linked to the inner case in which proper amount of reaction medium (20) is loaded. Shaft needles are fixed onto a loop shaft (19) and needle shafts (6) are respectively provided with rotatory loop shafts. The internal gas-guiding tube (10) communicates with the buffer case and the external case communicates with the external gas-guiding tube (11). The apparatus completes transfusion by pressurization based on the chemical reaction principle of quantitative gas-producing, which is characterized by easy operation, small-sized apparatus and continuous transfusion, etc. The apparatus can be applied to oxygen uptake or experiment oxygen supply and to various transfusion demands in clinical treatment such as in field rescuing, transporting process and in preventing cross-infection in the prevalence of infectious diseases.
Description
technical field [0001] The invention relates to a medical device, in particular to a portable gas-generating and pressurizing device that provides power for an infusion set Background technique [0002] At present, there are two types of infusion sets used for clinical intravenous drip: one is a gravity suspension type, and the other is a pressurized type. Gravity-suspended infusion sets are mainly used in hospitals. They have high requirements for diagnosis and treatment conditions, poor mobility, and high space height requirements. During clinical use, the care of accompanying personnel is required. The air introduced through the liquid is easy to contaminate the liquid or bring in germs. During use, various patients often gather in a small consultation room, especially during the epidemic period of infectious diseases such as respiratory tract, it is more likely to cause cross infection; at the same time, when the suspension height of the infusion bottle is insufficient, ...
