Abstract

The invention discloses automatic medicine change equipment for disposable multi-bottle infusion sets. The equipment comprises a plurality of punctures and a drip cup; a direction change device is commonly connected between the drip cup and the plurality of punctures, and the direction change device is divided into a plurality of liquid inlet connecting pipes, a liquid cavity and a liquid outlet connecting pipe from the top to the bottom in sequence; and a porous partition plate is installed on the inner wall of the liquid cavity, a plurality of positioning pipes are installed on the porous partition plate, a piston rod is slidably installed in each positioning pipe, and a rubber plug is installed on the upper end of each piston rod. According to the equipment, pressure difference is formed in the punctures through the puncture sequence of a plurality of medicine bottles, pressure is converted into pressure in a communicating device through the rubber plugs and the piston rods, and theremaining rubber plugs block the liquid inlet connection pipe, so that the effect of automatically changing medicine bottles for infusion according to the pressure sequence can be realized, mixed useor disorder of medicines can be avoided, and the safety of infusion can be increased; and the piston rods can be locked by air pipes and internal expansion airbags to further increase the safety of infusion.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to an automatic dressing changing device for a disposable multi-bottle infusion set. Background technique

[0002] During the flu season, the number of patients in the infusion hall increased, so the medical staff did not have much energy to manage more patients. Often, patients could not arrive in time to seek nurses for water changes.

[0003] Existing disposable infusion sets usually consist of a puncture needle and an infusion needle, which can only be inserted into a bottle of liquid medicine for infusion, and a patient usually needs to infuse three bottles at a time, so the liquid medicine needs to be replaced twice, which increases the workload of nurses . Contents of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that only one bottle of liquid medicine can be inserted at one time, and multiple bottles of liquid medi...
