Voice-activated myocardial protection perfusion system

Abstract

The invention discloses a voice-activated myocardial protection perfusion system, comprising a box body, a box cover and a sterile inner container, wherein the box body is internally provided with a control box, a first perfusion bottle, a second perfusion bottle, a first perfusion pump and a second perfusion pump, the control box is internally provided with a first microcontroller, a first powersupply module, a specific person voice recognition circuit, an information recognition module connected with a sound collection module, a first flow sensor and a second flow sensor, an output end of the first microcontroller is connected with a first driving module, a second driving module, a first valve drive and a second valve drive, and the sterile inner container is provided with a first sprayhead and a second spray head. The sterile inner container of the system can be taken out from the box body to be disinfected and sterilized, and a medical aseptic standard is met; the effect of voice-controlled myocardial perfusion is realized by the specific human voice recognition circuit, the sound collection module and the information recognition module, and the stable and safe internal environment is ensured when the myocardium is transferred in vitro, thus reducing the disinfection frequency during transfer.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a sound-activated myocardial protection perfusion system. Background technique [0002] Organ transplantation is a great achievement in the development of human medicine and has saved the lives of countless patients with terminal diseases. The prerequisite for the smooth implementation of organ transplantation is the availability of organs for transplantation. At present, clinical donor organ preservation mainly adopts the traditional static cold preservation technology. In general, 4-6 hours for the heart, 8-10 hours for the liver, and 24 hours for the kidneys. If the upper limit of cold ischemia time is exceeded, the incidence of complications such as primary transplanted liver nonfunction, delayed recovery of transplanted liver function, and biliary ischemic injury will increase significantly, and the postoperative survival rate of recipients will decrease...

AI Technical Summary

Problems solved by technology

Therefore, the disturbance of the internal environment is likely to cause the myocardium to be discarded due to the in vitro transport process.

[0007] If the organ is transplanted into the recipient without an effective evaluation of the organ by the transplant unit, the consequences will be even more disastrous, which will directly lead to the failure of the transplant and even the death of the patient

Detrimental impact on organ quality during organ transport not only leads to increased organ discard rates but also high post-transplant complications for patients

Of the more than 10,000 organs donated by citizens in my country every year, 15% have to be discarded due to complicated transfer procedures and low efficiency, which is a serious waste of organs

[0008] The existing myocardial transfer device often requires manual operation when perfusing extracellular fluid, and multiple disinfections are involved in the transfer process, which increases the risk of transfer
