Problems solved by technology

[0003] Especially for the problem that during the infusion of sedimentary medicinal liquid containing large cell clusters, medical staff need to shake it manually from time to time and the problem that some medicinal liquids need to be temperature-limited during the infusion process
And because the state of manual shaking has a great relationship with the experience of medical staff, the macromolecular cell clusters in the drug that have effective therapeutic effects will be inactivated due to temperature abnormalities and manual errors, which will not only delay the patient's condition and cause high costs. The waste of cell preparations will increase the workload of medical staff and occupy their time in rescuing critically ill patients

Embodiment １

[0033] The swinging infusion return device has input and output terminals. Patient tissue cells enter the instrument through the input port, and add drugs for tissue culture. Different culture methods are used according to the addition of drugs. After high-efficiency automatic tissue culture, the cells are infused back to the patient through the output port. in vivo.

[0034] The swing-type infusion return device is mainly composed of a box support part, a swing shake part, a medicine heating part, an exhaustion alarm part, and a central controller part. The supporting part of the box includes a stage 8, a storage box 9, a box body 10, a support rod 16 and its supporting fixtures, the stage is fixed on the bottom of the box, and the box is fixed on the box. The box body is fixed on the support bar with bolts and nuts. The swinging and shaking part is fixed on the stage, and the rotation of the shaft 7 will drive the stage 8 to swing at a fixed angle; the drug heating part is ...

Embodiment ２

[0041] When in use, multiple swinging infusion return devices can be installed in each ward of the hospital, and a central display monitor can be added in the nurse station. Refer to the following steps for details.

[0042]Turn on the machine first, and start the infusion work after confirming that all functions of the instrument are normal.

[0043] The first step is to extract suitable tissue cells from the patient's body, and after taking a small amount of tissue cells and confirming that they are correct, import them into the storage box medicine bag of the swinging infusion return device through the input port of the instrument.

[0044] In the second step, according to the patient's condition and the way of seeing a doctor, an appropriate medicinal liquid is selected and input into the device, so that the patient's tissue cells and the medicinal liquid coexist in the medicine bag of the storage box.

[0045] The third step is to set the appropriate rocking frequency, te...

Abstract

The invention relates to a swing type preparation feedback device. The swing type preparation feedback device comprises a swing power part, a drug heating part, a drug exhausting warning part and a controller, wherein the swing power part comprises a stepping motor, swing rods, connecting rods, a crank, a shaft and an object carrying platform; the drug heating part comprises a heating membrane and a temperature sensor; and the drug exhausting warning part comprises a buzzer and a photoelectric sensor. According to the swing type preparation feedback device, an AT89C51 single chip microcomputer is taken as a core, the stepping motor is controlled by virtue of a motor driving chip L298, the motor works to drive double-swing rod mechanism to move, the shaft is driven to rotate by the swing rods so as to drive the object carrying platform to swing, and therefore, medicine liquid in a medicine bag in a storage box is uniformly shaken. The temperature sensor is used for receiving temperature information, and the medicine liquid is heated by virtue of the heating membrane. The swing type preparation feedback device is further provided with an infrared sensor, and the photoelectric sensor is used for carrying out detection in a culture process of CIK cells and warning when a drug is exhausted. Therefore, the activity of the drug can be greatly increased, and the labor intensity of a medical worker can be greatly reduced; and the production cost is low, and the practicability is strong.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a swinging preparation reinfusion device. Background technique [0002] At present, intravenous therapy is an invasive treatment, and negligence in any part of the operation may lead to adverse results. Due to the different professional levels of medical staff, medical disputes caused by infusions have often occurred in domestic hospitals in recent years. [0003] Especially for the problem that during the infusion of the depositing medicinal solution containing large cell clusters, medical staff need to shake it manually from time to time and the problem that some medicinal solutions need to be temperature-limited during the infusion process. And because the state of manual shaking has a great relationship with the experience of medical staff, the macromolecular cell clusters in the drug that have effective therapeutic effects will be inactivated due to temperature abnormalities ...
