Automatic infusion switching device

Abstract

The invention relates to an automatic infusion switching device. The system comprises an infusion switching module and an automatic switching module, after the connecting pipeline is sleeved, the disposable connecting pipeline is connected to the infusion bag; when the infusion switching module is used, the fitting cover covers the infusion switching module body, and after the protrusion of the fitting cover is inserted into the step gap of the inner wall of the rotary fixing block, the protrusion and the step are rotated relatively, so that components are matched. The attaching cover rotates relative to the infusion switching module body in a one-way mode through the peak shifting sawteeth under the power effect of the automatic switching module, so that an infusion outlet in the attaching cover can be selectively aligned with the body and three through holes in the connecting pipeline base. Multi-bag infusion can be completed through one-time puncture. The number of times of pulling and inserting the puncture end of the infusion bag of the infusion apparatus is reduced, needle pricking injuries are reduced, the workload is reduced, the accumulative effect of adverse events is converted into the multiplicative effect, the implementation effect of all stages of the nursing procedure can be improved, and automation and intelligence of nursing work are facilitated.

Description

Technical field [0001] The present invention belongs to the field of medical device technology, relates to an automatic infusion switching device. Background [0002] At present, in clinical work, for a large number of infusion operations every day, the nurse's operation steps are: in the morning, each patient needs the infusion drugs to be corresponded to and claimed, the drugs are placed in the mobile nursing car, the first bag of infusion drugs of the day is connected to the patient, and the next bag of infusion drugs is removed from the nursing car after each bag of infusion drug instillation is completed, and the infusion bag is replaced in the ward, and the drug is continued with the infusion device. Usually, empirical statistics alone, the number of infusion drug bags per day can average 3 bags per patient, while each nurse can care for more than 10 patients in this day's shift. The total number of infusion medications that need to be changed each day can reach almost 50 b...

AI Technical Summary

Problems solved by technology

In the case of a low but non-zero occurrence probability of an adverse event such as check bias, there is an additive effect on the total occurrence probability of the independent check adverse event of the infusion bag

And if multiple infusion bags are connected for unified infusion, during the connection process, a single infusion bag connection error will make the entire verification process self-certifying, that is, any bag verification error will make the entire infusion bag connection system Cannot enter the patient's blood circulation
